STEAM Challenges using everyday household objects
Rocket straw
When students are stuck at home, it's good practice to extend their learning beyond the computer screen. The following 10 challenges are fun, hands-on and "unplugged" activities that help to reinforce students' knowledge and skills related to STEAM (Science, Technology, Engineering, Art and Maths):
 1. Create a paper "rocket" that will fly without being touched. (Clue: you will need a straw, paper and tape.)
 2. Grow a plant without soil. (Clue: you will need water, paper towels, a sponge, a clear plastic cup and quick-sprouting seeds such as grass or chia.)
 3. Move water from one cup to another without touching it. (Clue: you will need cups, water, paper towels and food colouring.)
 4. How do ducks and penguins stay dry in the water? Change a feather so it stays dry in the water. (Clue: you will need paper "feathers", crayons, oil, petroleum jelly, paintbrushes, and a spray bottle with water.)
 5. Build a bridge that is at least 30 cm long. It should be able to support at least 10 pennies in the middle. (Clue: you could use string, craft sticks, cardboard, tape, pennies.)
 6. Design several ramps to make a toy car travel slow, slower, and slowest. (Clue: you could use a toy car, cardboard ramps, string, play dough, sand paper, and rubbery shelf liner.)
 7. Make a car that moves without being touched. (Clue: you will need balloons, straws, paper & cardboard, craft sticks, dowels or skewers and magnets.)
 8. Use straws to create a device or vehicle that floats. (Clue: you will need straws, play dough, tape and a small tub of water.)
 9. Use only paper and tape to create a structure that will hold a heavy book. It must be able to stand on its own. (Clue: you will need paper, tape and heavy books.)
 10. Make a paper clip "float" in the air without touching it. (Clue: you will need magnets, paperclips, string, tape, craft sticks and lego blocks.

I have watched a part of TV show and the Muslim scholar was saying it is a must to let your beard grow and trim your mustache. I have always thought there is a kind of cultural influence and it is not a must to have it.
Is in a sin to shave your beard in Islam? is it a must to have a beard or else you will not be a good Muslim?

 I would typically discourage questions of a fiqhi nature because they're not suited for discussion on a forum of amateurs but I'm not flagging this one because the topic of the beard is of general interest and something that is highly visible, thereby inviting questions. – Ansari Jun 20 '12 at 16:01
 - -1 You didn't do your research. This is a well-established ruling. – ashes999 Jun 20 '12 at 16:54
Having a beard for a man (when it is possible) is wajib (obligatory) in Sunni Islam by consensus of almost all scholars and schools of thought. One of the many ahadith cited as evidence for this is the hadith from Abdullah b. Umar narrating from the Prophet (saws):
انْهَكُوا الشَّوَارِبَ، وَأَعْفُوا اللِّحَى
Trim the mustaches and leave the beard (to grow).
from Sahih al-Bukhari also in many other books
There is a difference of opinion within the Shafi'i school whether it's highly encouraged or obligatory.
For a Muslim, a hadith with a command from the Prophet (saws) is generally taken to describe an obligatory deed unless evidence suggests otherwise (from the principle "al-amru li al-wujoob").
Based on this hadith and many others like it, the scholars do say that it is a sin to shave the beard. As for whether or not you won't be a good Muslim without it, I don't see the connection. Being a good Muslim encompasses a number of things, from belief in the heart to kind actions to acts of worship. Not having a beard doesn't directly reflect on someone's character or the purity of their heart. But if not having a beard comes out of an arrogance or intentional disobedience of the Prophet (saws) then I guess that could have effects on others parts of one's Islam.

 Are you sure? Having bread is not Wajib, but shaving it is haraam. – user8749 Jun 20 '12 at 16:01

 Well if shaving it is haram, then having it (when possible) is wajib :) In any case, even aside from that argument, the standard position in Sunni fiqh at least is that it is wajib, with a caveat for a difference of opinion among some Shafi'is. – Ansari Jun 20 '12 at 16:03
 - Ah, you're quite right. They're the same thing! Please add the "Sunni fiqh" part to your answer. – user8749 Jun 20 '12 at 16:04

 Done - thanks for pointing that out. Curious now - what's the Shi'a fiqh on this? Ja'fari or Zaidi... – Ansari Jun 20 '12 at 16:07
 - A special shaving of beard is forbidden (haraam) in Shi'a Figh. One can use moser to shave beard to a level that you can't tell if he has from a fairly near distance. But I think there's not much of difference on this matter between n the two, only a slightly detailed one. – user8749 Jun 20 '12 at 16:24

Heritage Planning Program
The Heritage Planning Program of the Planning and Building Department is operated through the aegis of the Community Heritage Commission and Council. The program includes four ongoing initiatives:
- Heritage Conservation Projects
- Heritage Site Designations
- Burnaby Community Heritage Register
- Burnaby's Heritage: An Inventory of Buildings and Structures
Planning and Building Department is responsible for monitoring both privately-owned and civic heritage sites and ensuring their compliance with the City's bylaws, Heritage Revitalization Agreements and adopted heritage conservation standards. All properties identified in both the Heritage Register and Heritage Inventory qualify for incentive programs offered through the Heritage Planning Program.
Through the Heritage Planning Program the City of Burnaby has pursued offering incentives, including Heritage Revitalization Agreements for the protection of heritage buildings listed on the Community Heritage Register. The City's policy is to protect all buildings under municipal heritage site protection under the Heritage Conservation Act. The designation of municipal heritage sites provides for their legal protection. Under the legislation no building protected by a heritage designation bylaw can be altered or demolished. To date Burnaby has protected over 50 structures under Heritage Designation Bylaws or land title covenants.
The first Heritage Inventory of Burnaby, titled "Windows to Burnaby's Past", was completed by the Burnaby Historical Society in 1985. This inventory was adopted as a working document by the Heritage Commission in 1989. In 1992, Burnaby's centennial year, Burnaby Council implemented a Civic Heritage Policy and designated over 20 City-owned buildings as heritage sites.
A heritage building or site does not have to be over 100 years old to be listed on the Burnaby Heritage Register or the Burnaby Heritage Inventory. The oldest protected building in the City is the 1891 Wintemute House, while the newest heritage building is the 1965 Baldwin House, a modern masterpiece designed by Arthur Erickson.
There are over 170 resources listed on the Heritage Register and Heritage Inventory ranging from simple workers cottages to mansions and unique structures such as the 'Swinging Girl' neon sign. Burnaby Heritage buildings and structures form a valuable record of the development and change that has occurred in Burnaby's history. Approximately one-third of these sites are municipally designated and protected by municipal bylaw and listed on the Heritage Register.
The City of Burnaby maintains a Community Heritage Register under the provision of Section 954 of the Local Government Act which outlines that "A local government may, by resolution, establish a Community Heritage Register that identifies real property that is considered by the local government to be heritage property."
Protected Heritage Resources
There are over 50 heritage resources protected by City Council through Heritage Designation bylaws, Heritage Revitalization agreements and covenants. These individual resources are automatically updated and listed on the Canadian Register of Historic Places through the provincial government's participation in the program, as these properties form part of the British Columbia Register of Historic Places.
The Heritage Register – Protected Heritage Resources was adopted by Council in 2003. Detailed 'Statements of Significance' have been written and incorporated into the new Heritage Landmarks database on the Heritage Burnaby website.
The Council adopted Heritage Register - Protected Heritage Resources (updated to 2011), which includes over 50 heritage buildings and structures which are protected by individual bylaws, Heritage Revitalization agreements and Land Title covenants:
It is important to note that being listed on a Community Heritage Register in the Inventory category provides no formal protection for these individual buildings, but recognizes their heritage significance to the community and offers a management tool to be used by the City for future consideration of heritage protection through the implementation of available incentives through the Heritage Planning Program and the City's civic heritage stewardship program.
This category of the Heritage Register is under continual review and change. As heritage inventory properties in the City are identified for future heritage designation or a Heritage Revitalization Agreement, Council may by resolution add these properties to the Heritage Register - Inventory. When properties are protected through a heritage designation bylaw, they can be re-designated by Council resolution, and listed under the protected category of the Heritage Register. Similarly, if a heritage resource cannot be preserved by the City through offering available incentives, a property could be removed from the inventory through Council Resolution.
The Heritage Register - Heritage Resource Inventory was adopted by Council in 2003 and detailed 'Statements of Significance' have been written and incorporated into the new Heritage Landmarks Database on the Heritage Burnaby website.
The City has been using a heritage resource inventory since 1989 to track all of the City's significant public and privately-owned heritage buildings and resources that are not protected by heritage designation bylaws and not listed on the Burnaby Community Heritage Register. As inquiries are received for these properties the City's Heritage Planner will review the property's status and work with the property owner in order to facilitate any proposal for its conservation. Approval of any upgrade of an inventory property to become part of the Burnaby Heritage Register is undertaken with the review of the Community Heritage Commission and Council consideration and adoption.
In 2007 the Community Heritage Commission completed a new heritage inventory "Burnaby's Heritage: An Inventory of Buildings and Structures" which is the culmination of many years of effort to identify and evaluate the built heritage of the City. This new inventory includes both those heritage resources adopted by Council for the BCHR and properties eligible for inclusion.
It is important to note that listing a property on this inventory does not constitute heritage protection. There are no financial or redevelopment restrictions for private or public owners of heritage resources when a property is listed in a heritage inventory. Rather, the inventory is a heritage management tool which serves the stewardship of heritage resources by providing wider public awareness of heritage resources located throughout the City.
The inventory forms a cornerstone of the City's Heritage Program to identify and create public awareness of the rich history and architectural landmarks that contribute to the character of our city's unique neighbourhoods. The inventory was adopted by the Community Heritage Commission and has been incorporated with its historical and architectural information into the new Heritage Landmarks database on the Heritage Burnaby website.
To search for a property listed on the inventory you can search the Online Database located on the Heritage Burnaby Website or review the printed version of the document: Burnaby's Heritage: An Inventory of Buildings and Structures.

According to the Texas Probate Code, stepchildren have few rights to inherit from their stepparents if they die without valid wills. A person who dies without a will is an intestate. An intestate's heirs have a right of succession as determined by the Texas Probate Code. A stepchild does not have a right to either of his stepparent's intestate property under the Texas Probate Code because the state does not consider him a legal relative. This is true even when a stepparent has a very close relationship or bond with his stepchild. It also applies to a child of a single parent who later marries and the new husband or wife raises his spouse's natural child.
The limited exception to the general rule that stepchildren cannot inherit from their stepparents absent a valid will is when a stepparent legally adopts his stepchild or promises to adopt the child but later does not. In the latter situation, if the stepchild can prove the existence of a valid oral or written contract promising to adopt him, he may inherit from his stepparent who died without a will.

|Laude & IT|
In the era of communications and globalisation comprehensive academic formation is far from being sufficient, no matter how substantial this may be. The educational process has to be accompanied by the perfect command of at least one foreign language, and also be fully acquainted with all those tools currently being used in new technologies. In view of this and by means of its educational project, LAUDE El Altillo School ensures that once the students complete their Bachillerato studies they are able to communicate perfectly in the English language, and, on the other hand, by working with computers and specific software on a daily basis, they are fully conversant with all relevant computer applications.
The School is very conscious of how important it is to teach our students to be fully conversant in the use of computer tools, and for this reason all our students have fully equipped classrooms in which, in addition to the hours spent in acquiring knowledge on the specific objectives on the subject of new technology, also have the possibility of using this fantastic educational tool for other subjects such as English, Science, Mathematics, etc.

Children disappointed as teacher pulls down blinds to stop them being distracted by snow during lesson at Stalham Academy near Great Yarmouth
Children at Stalham Academy, near Great Yarmouth, were banned from looking at snow Photo: Andrew Crowley
By Agency
A primary school has been criticised by parents after pupils aged eight and nine were banned from watching snow outside their classroom window.
Children were left disappointed after their teacher pulled down blinds to stop them being distracted by snow during a lesson.
Parents also claimed that pupils were stopped from touching the snow when they arrived at Stalham Academy near Great Yarmouth, Norfolk.
Charlotte Marsters, 39, said her nine-year-old daughter had been excited by last Monday's snowfall and was very disappointed when the blinds were closed.
She said: "It was so dark they had to put the lights on. They were stuck in all day as they weren't allowed to play in the snow - and there was only about 1cm."
Ms Masters said children had been "marshalled" into classrooms as snow fell and were stopped from even bending to touch it.
She claimed one boy was told off after he took a small amount of snow from a wall with a gloved hand.
Mother-of-six Shelly Betts, whose eight-year-old daughter Bethany is a pupil, said: "When she told me they'd shut the blinds I couldn't believe it - I was very upset.
"They're only little, and they only stay children for a short time. They could have turned the snow it into a science lesson instead of banning them from seeing it. By the time they came out of school it was all gone.
"I don't want it to end up with my children only knowing about snow from Christmas cards."
Julie Hollins, 30, who has an eight-year-old son at the school, said: "Stopping them from even seeing it fall is like a slap in the face for little children."
Valerie Moore, chief executive of the Rightforsuccess Academy Trust which runs the school, did not respond to a request for comment.
However, a message posted on the Facebook page said: "We acknowledge that snow is an unusual and exciting occurrence for everyone, especially children.
"The academy's playgrounds were extremely icy so it was felt that in the interest of safety and in line with our risk assessment under health and safety, that children were brought inside at the start of the day.
"The phrase'marshalling' is not accurate to describe a notice board asking children to go inside, nor is it accurate in regards to the manner that children are brought into the Academy.
"Over the course of the day the ice had not cleared by break time on the Monday and sleet and snow showers prevented outdoor play at lunchtime.
"Having discussed the matter with the class teacher in question, she noted that the heavy snow fall was having an impact upon the learning of the children during one of her lessons so the blinds were closed to ensure that children focussed on their tasks in hand."
The school made headlines before Christmas when Stalham curate, the Rev Margaret McPhee, announced that father Christmas was not real during a school carol service, leaving some pupils upset. She later apologised.

Purdue researchers Presented at AAAI
C-BRIC researchers at Purdue University presented at the 37th AAAI Conference on Artificial Intelligence. Gobinda Saha and Kaushik Roy presented their work "Continual Learning with Scaled Gradient Projection" at the AAAI conference held in Washingto, DC February 7-14, 2023. AAAI is a research conference held to promote work in the area of Artificial Intelligence (AI). The conference is held to "foster scientific exchange between researchers, practitioners, scientists, students, and engineers across the entirety of AI and its affiliated disciplines" with the intent to create collaborations "within and beyond AI."
Saha and Roy presented "Continual Learning with Scaled Gradient Projection" which focuses on catastrophic forgetting during continual learning. They proposed the Scaled Gradient Projection (SGP) method in this work to "improve new learning while minimizing forgetting." SGP is an "efficient method for computing and accumulating importance... using the singular value decomposition of the
input representations for each task." The method results in better performance and less training overhead.
Gobinda Saha is currently a PhD student at Purdue University under the direction of Kaushik Roy. Roy is the C-BRIC Director and a faculty member at Purdue University.


The Government Wants To Have One Big File On You, Including Info From Your Taxes And Your Driving Offences
The government would need to pass legislation before it could pass on personal data from one department to another.
2. The government is considering passing legislation to allow departments to share information it has about citizens, including everything from criminal offences and qualifications to how much you spend on energy.
Politicians think compiling all this information in one area will allow the government to more effectively formulate policy based on evidence to "tackle social mobility, assist economic growth and prevent crime", according to the document. But it is believed ministers could pass legislation that would allow departments to pass on information about individual citizens without their consent, the Telegraph reports.
3. The remarks appear in a "initial discussion document" produced in April by the Cabinet Office Data Sharing Policy Team. BuzzFeed has obtained a copy of the document, which you can view here:
View this embed ›
The introductory paragraph sets out exactly why these discussions are taking place. It says: "People tend to assume that government can share data between departments to complete simple tasks, and are surprised to learn that it cannot."
4. Part of the problem, according to the document, is that government bodies can't currently share multiple data sets. But movement towards doing so could cause concerns among privacy advocates as this data would not be entirely anonymised.
In many cases, research on government and public body data is limited to the analysis of single data sets which, if the researchers are external to government, is almost always of anonymised or de-identified data. Consequently the possibility of undertaking deeper research using cross-linked but separate data sets is difficult or impossible. Bodies holding the data can be reluctant to undertake such shares and analysis because they lack the necessary powers to share information or are subject to a statutory bar. Those outside government can find it difficult to access data in the first place and then cross-link two or more de-identified sets of data.
To assist in overcoming these issues, the report by the Administrative Data Taskforce Improving Access for Research and Policy … recommended a model of data sharing that allowed for such cross-linked research on de-identified data to take place, whilst at the same time maximising privacy protection for data subjects by restricting access to and the use of identity data to the absolute minimum required to cross-link the datasets. There are two variants of the model … but the majority of structural elements are the same for both.
5. There might also be concerns that personal data would be shared with an "external data processor", which could be a public organisation.
"1. Proposals could provide all UK public bodies with a discretionary power to:
a. Disclose both personal data and other data to an accredited external data processor (who could be either a public or a private body but not one of the data owners who are the source of the information) for the purpose of indexing against another dataset (which has been provided on the same basis from another data owner). Data owners would be able to disclose whatever type of data is necessary in order for the indexer to be able to match records between the datasets. For example, in many cases an address will be a useful type of data to use as an identifier, but if the research focused on homeless people then it is unlikely to be useful; another data type might be used instead."
But before this happens, the government might need to allay public concerns over whether it can actually be trusted. In 2007, it misplaced the details of 25 million people (or 7 million families) after they went missing in the post. This included their dates of birth, addresses, bank accounts, and national insurance numbers, leaving many open to threats of fraud.
6. Draft legislation is likely to be published in the autumn and introduced in the next government if the Conservative party wins a majority.

Objectives: We investigated the quality of 162 variables, focusing on the contribution of genetic markers, used solely or in combination with other characteristics, when predicting mortality.
Methods: In 5974 participants from the Rotterdam Study, followed for a median of 15.1 years, 7 groups of factors including age and gender, genetics, socioeconomics, lifestyle, physiological characteristics, prevalent diseases, and indicators of general health were related to all-cause mortality. Genetic variables were identified from 8 genome-wide association scans (n = 19,033) and literature review.
Results: We observed 3174 deaths during follow-up. The fully adjusted model (C-statistic for 15-year follow-up [C15y] = 0.80; 95% confidence interval [CI] = 0.79, 0.81) predicted mortality well [corrected]. Most of the additional information apart from age and sex stemmed from physiological markers, prevalent diseases, and general health. Socioeconomic factors and lifestyle contributed meaningfully to mortality risk prediction with longer prediction horizon. Although specific genetic factors were independently associated with mortality, jointly they contributed little to mortality prediction (C(15y) = 0.56; 95% CI = 0.55, 0.57).
Conclusions: Mortality can be predicted reasonably well over a long period. Genetic factors independently predict mortality, but only modestly more than other risk indicators.


impala-shell Command Reference
Use the following commands within impala-shell to pass requests to the impalad daemon that the shell is connected to. You can enter a command interactively at the prompt, or pass it as the argument to the -q option of impala-shell. Most of these commands are passed to the Impala daemon as SQL statements; refer to the corresponding SQL language reference sections for full syntax details.
Command Explanation
Changes the underlying structure or settings of an Impala table, or a table shared between Impala and Hive. See ALTER TABLE Statement and ALTER VIEW Statement for details.
compute stats
Gathers important performance-related information for a table, used by Impala to optimize queries. See COMPUTE STATS Statement for details.
Connects to the specified instance of impalad. The default port of 21000 is assumed unless you provide another value. You can connect to any host in your cluster that is running impalad. If you connect to an instance of impalad that was started with an alternate port specified by the --fe_port flag, you must provide that alternate port. See Connecting to impalad through impala-shell for examples.
The SET statement has no effect until the impala-shell interpreter is connected to an Impala server. Once you are connected, any query options you set remain in effect as you issue a subsequent CONNECT command to connect to a different Impala host.
Shows the columns, column data types, and any column comments for a specified table. DESCRIBE FORMATTED shows additional information such as the HDFS data directory, partitions, and internal properties for the table. See DESCRIBE Statement for details about the basic DESCRIBE output and the DESCRIBE FORMATTED variant. You can use DESC as shorthand for the DESCRIBE command.
Removes a schema object, and in some cases its associated data files. See DROP TABLE Statement, DROP VIEW Statement, DROP DATABASE Statement, and DROP FUNCTION Statement for details.
Provides the execution plan for a query. EXPLAIN represents a query as a series of steps. For example, these steps might be map/reduce stages, metastore operations, or file system operations such as move or rename. See EXPLAIN Statement and Using the EXPLAIN Plan for Performance Tuning for details.
Help provides a list of all available commands and options.
Maintains an enumerated cross-session command history. This history is stored in the ~/.impalahistory file.
Writes the results of a query to a specified table. This either overwrites table data or appends data to the existing table content. See INSERT Statement for details.
invalidate metadata
Updates impalad metadata for table existence and structure. Use this command after creating, dropping, or altering databases, tables, or partitions in Hive. See INVALIDATE METADATA Statement for details.
Displays low-level information about the most recent query. Used for performance diagnosis and tuning. The report starts with the same information as produced by the EXPLAIN statement and the SUMMARY command. See Using the Query Profile for Performance Tuning for details.
Exits the shell. Remember to include the final semicolon so that the shell recognizes the end of the command.
Refreshes impalad metadata for the locations of HDFS blocks corresponding to Impala data files. Use this command after loading new data files into an Impala table through Hive or through HDFS commands. See REFRESH Statement for details.
rerun or @
Executes a previous impala-shell command again, from the list of commands displayed by the history command. These could be SQL statements, or commands specific to impala-shell such as quit or profile.
Specify an integer argument. A positive integer N represents the command labelled N in the output of the HISTORY command. A negative integer -N represents the Nth command from the end of the list, such as -1 for the most recent command. Commands that are executed again do not produce new entries in the HISTORY output list.
Specifies the data set on which to complete some action. All information returned from select can be sent to some output such as the console or a file or can be used to complete some other element of query. See SELECT Statement for details.
Manages query options for an impala-shell session. The available options are the ones listed in Query Options for the SET Statement. These options are used for query tuning and troubleshooting. Issue SET with no arguments to see the current query options, either based on the impalad defaults, as specified by you at impalad startup, or based on earlier SET statements in the same session. To modify option values, issue commands with the syntax set option=value. To restore an option to its default, use the unset command. Some options take Boolean values of true and false. Others take numeric arguments, or quoted string values.
In Impala 2.0 and later, SET is available as a SQL statement for any kind of application, not only through impala-shell. See SET Statement for details.
In Impala 2.5 and later, you can use SET to define your own substitution variables within an impala-shell session. Within a SQL statement, you substitute the value by using the notation ${var:variable_name}.
Executes the specified command in the operating system shell without exiting impala-shell. You can use the! character as shorthand for the shell command.
Displays metastore data for schema objects created and accessed through Impala, Hive, or both. show can be used to gather information about objects such as databases, tables, and functions. See SHOW Statement for details.
source or src
Executes one or more statements residing in a specified file from the local filesystem. Allows you to perform the same kinds of batch operations as with the -f option, but interactively within the interpreter. The file can contain SQL statements and other impala-shell commands, including additional SOURCE commands to perform a flexible sequence of actions. Each command or statement, except the last one in the file, must end with a semicolon. See Running Commands and SQL Statements in impala-shell for examples.
Summarizes the work performed in various stages of a query. It provides a higher-level view of the information displayed by the EXPLAIN command. Added in Impala 1.4.0. See Using the SUMMARY Report for Performance Tuning for details about the report format and how to interpret it.
The time, memory usage, and so on reported by SUMMARY only include the portions of the statement that read data, not when data is written. Therefore, the PROFILE command is better for checking the performance and scalability of INSERT statements.
In CDH 5.5 / Impala 2.3 and higher, you can see a continuously updated report of the summary information while a query is in progress. See LIVE_SUMMARY Query Option (CDH 5.5 or higher only) for details.
Removes any user-specified value for a query option and returns the option to its default value. See Query Options for the SET Statement for the available query options.
In CDH 5.7 / Impala 2.5 and higher, it can also remove user-specified substitution variables using the notation UNSET VAR:variable_name.
Indicates the database against which to execute subsequent commands. Lets you avoid using fully qualified names when referring to tables in databases other than default. See USE Statement for details. Not effective with the -q option, because that option only allows a single statement in the argument.
Returns Impala version information.


5 Ways to Clean a Wooden Cutting Board
The dishwasher may be a foe to most wooden cutting boards, but not to worry — getting the board extra clean doesn't require much beyond some products likely found in your home.
Make Ahead
2. Disinfect using 3 percent hydrogen peroxide. Pour it over the board and spread it around using a clean sponge. Let it stand for a few minutes as it fizzes and kills germs. Wipe off with the clean sponge and repeat as needed.
3. Remove stains with coarse salt or baking soda. Dry the board completely and sprinkle it with the salt or baking soda. Scrub out the stain using a sponge or a brush dipped into hot water and repeat as needed.

Question: Do Tomatoes Scream When You Cut Them?
Does a plant feel pain when you cut it?
Do tomatoes cry?
Drought-stressed tomato plants emitted about 35 ultrasonic squeals per hour, on average, while those with cut stems made about 25. Drought-stressed tobacco plants let out about 11 screams per hour, and cut crops made about 15 sounds in the same time.
Does grass scream when you cut it?
Scientists have discovered that grass blades scream when cut with a lawnmower. … While human ears can only hear sounds up to about 16,000 Hz, scientists have now measured vocalizations of 85,326 Hz emanating from grass blades cut by a power lawn mower.
Do cucumbers scream when you cut them?
Although not audible to the human ear, the secret voices of plants have revealed that cucumbers scream when they are sick, and flowers whine when their leaves are cut [source: Deutsche Welle]. There's also evidence that plants can hear themselves being eaten. … This network helps plants propagate, grow and survive.
Do trees have genders?
Lots of trees are hermaphroditic — that is, their flowers contain both male and female reproductive parts. Other species have male trees and female trees, which you can tell apart by looking at their flowers: The male reproductive parts are the pollen-laden stamen; the female parts their egg-holding pistils.
Do plants die if you yell at them?
Marini does admit that sound waves can have an effect on plants because they make them vibrate, and that vibration causes the plants to create ethylene, stunting their growth, but adds that sound would not cause them to wilt and certainly wouldn't kill them.
Do plants feel love?
Plants Really Do Respond to The Way We Touch Them, Scientists Reveal. It's something that plant lovers have long suspected, but now Australian scientists have found evidence that plants really can feel when we're touching them.
What happens if you never cut grass?
After long periods without mowing, the grass may go to seed, causing the blades to look more like weeds than grass. In addition to decreased curb appeal, excessively tall grass puts the homeowner at risk for complaints. Many cities require homeowners to keep the lawn mowed.
Why does grass smell when it's cut?
What's the secret behind the sweet smell of cut grass? … Chemically speaking, that classic lawn smell is an airborne mix of carbon-based compounds called green leaf volatiles, or GLVs. Plants often release these molecules when damaged by insects, infections or mechanical forces — like a lawn mower.


When the Computer Wore a Skirt: NASA's Human Computers
Human Computers exhibitThe NASA exhibit explores the history and personalities brought to light in the hit film and best-selling book "Hidden Figures." In 1935 a group of five women came to Langley to form a computer pool to process all the data coming in from wind tunnel and flight tests. It started as an experiment but became something much bigger. In the 1940s Langley began recruiting African-American women as human computers, but due to segregation laws these "West Area Computers" were kept separate from their white counterparts. This changed in the 1950s as NACA (later NASA) integrated and the "human computers" extended into the broader scientific community at NASA. By the 1960s they numbered in the hundreds. This exhibit features three of these pioneers: Dorothy Vaughn, Katherine Johnson and Mary Jackson.

I need to show specifically using transfinite induction that given two well-ordered sets $\left(A,<_{1}\right)$ and $\left(B,<_{2}\right)$ there is only one isomorphism between them. To do this I want to show by induction that there is only one way to define the mapping and that is: $$\forall\, x\in A: \varphi\left(x\right)=\min\left(B\backslash\varphi\left(\left\{ a\in A\,:\, a<_{1}x\right\} \right)\right)$$ Showing the base of the induction is no problem and the induction hypothesis would be that $$\forall\, y<_{1}x\,:\,\varphi\left(y\right)=\min\left(B\backslash\varphi\left(\left\{ a\in A\,:\, a<_{1}y\right\} \right)\right)$$ My problem is that I can't seem to manage to use the hypothesis in order to prove the step. I've found a couple of ways to show this definition of the mapping is indeed necessary but none of those used the induction hypothesis. My plan was to mark $$c_{0}=\min\left(B\backslash\varphi\left(\left\{ a\in A\,:\, a<_{1}x\right\} \right)\right)$$ Using the fact $\varphi$ is surjective take $y\in A$ such that $\varphi\left(y\right)=c_{0}$ and show that it can't be that $y<_{1}x$ or $x<_{1}y$ and thus necessarily $y=x$. If someone could give me a way to show either one of these are false using the induction hypothesis it would solve my problem.
Thanks a lot!

What you want to show is that if $f\colon A\to B$ is an isomorphism of the given well-orders then $f=\varphi$.
Suppose that for $x\in A$ we have that $f\upharpoonright\{a\in A\mid a<_1 x\}=\varphi\upharpoonright\{a\in A\mid a<_1 x\}$. If $f(x)=\varphi(x)$ then we may continue the induction; otherwise $\varphi(x)

Risk factors for cardiac dysfunction in children on treatment for cancer at Kenyatta National Hospital, Nairobi
Citation:
Shiroya-Wandabwa M, Yuko-Jowi C, R W Nduati, Githanga J, Wamalwa D. "Risk factors for cardiac dysfunction in children on treatment for cancer at Kenyatta National Hospital, Nairobi.". 2012.
Abstract:
To determine the point prevalence of abnormal cardiac function and to assess the risk factors for cardiac dysfunction in paediatric oncology patients on treatment at Kenyatta National Hospital. DESIGN: Descriptive cross-sectional study with a nested case control. SETTING: Kenyatta National Hospital between February and April 2006. MAIN OUTCOME MEASURES: Left ventricular dysfunction if ejection fraction (EF) <55% or fractional shortening (FS) <29% defined cases. Controls had EF >55% or FS >29%. RESULTS: One hundred and eleven patients were enrolled of whom 32 had abnormal cardiac function and were classified as cases while 79 had normal cardiac function. About a third, point prevalence 29% (95% CI 21.2-37.9), had cardiac dysfunction. Cumulative anthracycline dose was a risk factor for cardiac dysfunction in this population. Above 200 mg/m2 the attributable risk percentage of cardiac dysfunction was 77%. CONCLUSIONS: Serial echocardiography should be performed to identify patients at risk. Alternative treatment protocols should be used when the cumulative anthracycline dose exceeds 200 mg/m2 due to the high attributable risk. Studies to further assess the other associated risk factors and long term effects of anthracycline are recommended.

Microstructure profiles from the N/O Pourquoi Pas? are done! This instrument, operated by Francesco Falcieri coming from an Italian Institute based in Venice (CNR-ISMAR), will be moved onto the RV SOCIB during our port call in Almeria on April 3rd.
The profiler free-falls vertically through the water column to measure very small vibrations at scales of centimetres. Scientists used those measurements to infer turbulence activity in the ocean that mixes water irreversibly. But the profiler also measures other variables, such as temperature, conductivity, turbidity and fluorescence. We collected 43 profiles over this first week – with more to come from the RV SOCIB!

Future applications of miniaturized space systems will have special needs on MEMS components. This paper addresses
the needs, status and perspectives of the MEMS technology for miniaturized space system from the perspective of a
spacecraft developer. First, the needs of future space missions on MEMS components are discussed. Then, the state-of-the-
art MEMS technologies are reviewed based upon these needs. Finally, perspectives of space-based MEMS
technology will be addressed based on the analysis of both future mission needs and technological trends.


Basic definitions
Dewpoint temperature
The temperature to which the gas must be cooled in order that it should be saturated with water vapour (i.e. 100% relative humidity).
For practical reasons it is referred to water above 0 °C (+32 °F) and ice below 0 °C (+32 °F).
Dewpoint is expressed in degrees Celsius (°C) or degrees Farenheit (°F).
Water vapour pressure
The pressure exerted by the water vapour contained in any mixture of gases. The total pressure exerted by the gas mixture is the sum of the pressures exerted by its components – including the water vapour. Water vapour pressure varies in direct proportion to the total gas. Expressed in units of pressure such as pascals (Pa), millibar (mbar) or millimeters of mercury (mmHg).
Saturation water vapour pressure
The maximum pressure of water vapour that can exist in a gas at a given temperature. Expressed in units of pressure as partial water vapour pressure.
Parts per million by volume
The ratio of the water vapour pressure to the total gas pressure, expressed as ppm(v) or vpm.
Parts per million by weight
The figure is modified according to the ratio of the molecular weight of water vapour to the molecular weight of the carrier gas mixture, expressed as ppm(w).
Absolute humidity
The mass of water vapour in a unit volume of moist gas at a given temperature and pressure. Expressed as grams per cubic metre (g/m³), milligrams per litre (mg/L), milligrams per cubic metre (mg/m³) or pounds of water per million cubic feet of gas (lb/MMSCF).
Relative humidity
The ratio of actual water vapour pressure in the gas to the saturation water vapour pressure at the same temperature.

This interesting name has two possible origins, the first of which is Anglo-Saxon, and forms either a metonymic occupational surname for a grower or seller of pears, or a topographical name for someone who lived by a conspicuous pear tree or by a pear orchard. In this instance the name derives from the Old English pre 7th Century 'pere, peru', pear, itself derived from the Latin 'pirum', and which became 'pe(e)re' in Middle English. The second possible source for the modern surname, found as Pear, Peare, Pere, Peer and Peear, is from the Medieval English 'nickname' surname for a companion, peer, a'match', derived from the Middle English 'pere', developed from the Old French 'per, peer', a peer, paragon, from the Latin 'par', equal.The marriage of one John Peare and Agnes Ashe was recorded at St. Botolph's, Bishopsgate, London, on February 25th 1592. The first recorded spelling of the family name is shown to be that of Osbert Pere, which was dated 1230, The Berkshire Pipe Rolls, during the reign of King Henry 111, 'The Frenchman', _PHONE_. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.

Background: Beak Trimming and Feather Pecking in Laying Hens
Injurious feather pecking is a major welfare problem in laying hens which can occur in all types of rearing systems, including free-range systems that have a higher welfare potential. In the most severe cases it can lead to cannibalism. In order to reduce the risk of feather pecking and cannibalism, hens are usually beak trimmed. This consists of amputating one third to a half of the bird's beak using a red hot blade or infra-red beam. Beak trimming leads to tissue and nerve damage and is associated with acute pain, irrespective of the method used.
Insufficient opportunity to carry out foraging behaviour is widely accepted as a primary risk factor for feather pecking. However, the causes of this abnormal behaviour are multi-factorial with risk factors – including genetics, environment, health and management. It is therefore important to address them all in order to prevent injurious pecking and to successfully operate a laying hen rearing system without the need to beak trim.
The Rondeel system is a unique barn system, with many features in which the hens are not beak trimmed. This case study highlights the key features and management aspects of this system which make it possible to rear laying hens with beaks intact, without resulting in injurious feather pecking.
Overview of the Rondeel Barn System
Rondeel is an enriched barn system for laying hens, owned by the Dutch Venco Group. There are currently three Rondeel farms located in The Netherlands, and the system is also available for franchise. Rondeel eggs are mainly sold in Albert Heijn retail stores, at an intermediate price between free-range and organic.
A Rondeel barn accommodates 30,000 birds and has a characteristic circular design split into 10 sub-units, each housing 3,000 hens (see illustration on the left).
Each unit is divided into three distinct areas in order to better address the hens' behavioural and mental needs and give them the freedom to choose their environment.
The three distinct areas
1. Multi-tiered night quarters with three separate levels for feeding, nesting and egg laying, and perching (see picture on the left). The bottom tier is composed of a layer of litter for scratching and dust-bathing. The second tier incorporates nesting boxes while the third tier provides aerial perches, allowing birds to feel safe whilst resting. Feeding stations are provided on the first and third tiers.
2. Spacious day quarters (or veranda – see picture on the right) which provide more space than is required by EU regulation – 6.7 birds/m² vs. 9 birds/m² – and natural light (transparent ceiling). This area is covered in artificial grass and grain is scattered every morning to encourage foraging. Dust bathing areas are provided with open-sided screens.
3. An enclosed outdoor area (see picture on the left) enriched with wood trunks and access to soil for dust bathing. When open, this area reduces the indoor stocking density to 5.2 birds/m², providing a very generous space allowance. The area is covered with netting to prevent wild birds from entering the system and spreading disease. Tree trunks have been provided to create opportunities for perching and hiding.
Keys to success: How Rondeel has managed to stop beak trimming
Several features of the Rondeel barn design are key to preventing injurious pecking, including:
- A multi-tier system in the night quarters, which provides a more complex environment than a single-tier system, and is more similar to the chicken's natural woodland habitat.
- Aerial perches help prevent feather pecking as they create opportunities for resting and refuge by enabling resting birds to avoid being pecked by foraging birds. They also avoid mixing active and inactive birds by providing distinct resting areas.
- Ranging opportunities - the whole length of the house can be opened for the birds to go outside. Ranging is encouraged in the day quarters by scattering grain daily and providing natural light in a fully covered area – allowing the hens to range while being protected from adverse weather. The provision of wood trunks and wood shavings and the presence of a sandy surface and drainage system to avoid puddles also help to increase the use of the outdoor run. Finally, the presence of drinking points in the day quarters, encourage the birds to range in this area. Increased use of the range is strongly associated with a reduced risk of feather pecking.
- Plenty of environmental enrichment with the provision of nesting boxes and aerial perches in the night quarters, dust bathing areas, artificial grass in the day quarters, wood trunks and wood shavings in the outside run. This diverse and interesting environment is important to allow the expression of a range of natural behaviours such as foraging, perching and dust bathing, which helps prevent injurious pecking.
- A lower stocking density gives the birds more space; 9 birds/m² in the night quarters, reducing to 6.7 birds/m² when the day quarters are open and down to 5.2 birds/m² when the outdoor run is also open.
- Provision of adequate litter in the night quarters, which has been shown to reduce the incidence of feather pecking. The artificial grass in the day quarters is also a unique addition which encourages the hens to scratch, peck, rest and range.
- Climate control, with sensors placed on the rolling doors that separate the day and night quarters, controlling the opening of the doors according to the temperature and creating a uniform climate between the day and night quarters, helps encourage the hens into the day quarters to range and forage.
- Reducing group size within the barn which is divided into 10 sub-groups. The risk of feather pecking is generally lower in hens that are kept in smaller groups than in larger flocks as they are able to establish stable social interactions.
Feeding regime and opportunities for foraging
- Daily scattering of grain, which provides an opportunity for natural foraging behaviour. Increasing the length of time the birds spend foraging and feeding is likely to reduce the incidence of feather pecking.
Genetics and breeding
- The use of the Lohmann Brown Lite breed, which seems to have a lower propensity to feather peck.
Key Learnings and Take Home Messages
As successfully demonstrated in the Rondeel barn system, it is possible to stop beak trimming without resulting in injurious feather pecking. This can be achieved with a good housing and feeding system, a varied environment, appropriate choice of genetics, good flock management and climate control.
Key aspects to successfully stop beak trimming and reduce the risk of feather pecking in a cage-free rearing system include:
- Creating opportunities for resting and refuge and avoiding mixing active and inactive birds, especially through the provision of aerial perches
- Providing ranging opportunities and encouraging the use of the range, especially through the provision of environmental enrichment and outdoor tree cover
- Increasing the length of time the birds spend engaged in foraging and feeding especially through the daily scattering of grain or feeding a high fibre, low-energy diet of mash rather than pellets
- Choosing appropriate strains of hens, less prone to feather pecking, such as the Lohman Brown Lite breed.
Early experiences during the rearing period (before laying) should also be considered as they have a significant impact on the future tendency of the hens to feather peck. Housing, feeding and management conditions during the rearing and laying periods should be matched as closely as possible to reduce the risk of feather pecking later in life.

GraphicsJS Fill Settings
Fill settings define how a shape inner area is drawn. All Shapes and closed Paths have the fill() method.
Solid color
The most simple fill is a solid color fill. Color can be set as rgb, rgba, hex, hsl, hsla or web constant, just as you do in CSS Color.
Color opacity can be set in two ways:
 - RGBA, HSLA modificators;
 - Dedicated parameter:
 - Call function with the parameters fill(color, opacity);
 - Single value fill('color opacity') (one string value separated by space).
Linear Gradient
Gradient key
Gradient is a required parameter to set linear gradient, it consists of two or three values: gradient position, color and opacity as an option. If you have only one key the fill will be solid.
Gradient position is set by a number from 0 to 1, where 0 and 1 are gradient borders. If gradient position is not set manually, it will be calculated automatically depending on the number of keys.
Gradient key settings: 'position color opacity' or
 position:,
 color:,
Here is an example of two-step linear gradient:
.fill(['red', 'yellow'])
And here is an example of multiple-key linear gradient:
.fill(['0.1 red', '.3 yellow', '.6 white', '.9 orange'])
Additional values
 - opacity - sets an opacity value for gradient;
 - angle - sets gradient angle, depending on the mode;
 - fill mode - as described below.
Fill modes
ObjectBoundingBox without angle value preservation
In this mode, AnyChart charting framework calculates gradient vector with the preset angle, but the result gradient angle on the rendered page can be changed if the object proportion is not 1:1 in the browser. So visually the result gradient angle may not correspond to the original settings.
ObjectBoundingBox with angle value preservation
In this mode the result angle will visually correspond the original setting, non regarding browser scaling duplication (so, for objects that do not have 1:1 proportion with the original figure, the gradient angle will correspond to the initial value due to internal calculations).
Please see the following illustration of these modes:
// no angle preservation
.fill(['0.4 black', '.6 white'], 45)
// angle preservation
.fill(['0.4 black', '.6 white'], 45, true)
In this mode gradient settings are added by gradient size and borders/coordinates, and rendering is calculated within those borders. After that, the fill is executed on the element figure according to its coordinates.
This can be shown in the following way:
 keys: ['.1 red', '.5 green', '.9 blue'],
 angle: -45,
 mode: anychart.math.rect(150, 70, 100, 50),
 opacity: 1
Gradient settings are set by 'fill settings', and these gradient fills figures 1-3.
If the container size in gradient settings are larger than the filled element size, it will result in the following:
 angle: -45,
 mode: anychart.math.rect(5, 0, 395, 200),
 opacity: 1
Radial Gradient
Radial Gradient basic parameters are:
 1. Gradient keys, just like in linear gradient,
 2. Center location, which is set by a number from 0 to 1 as a percentage ratio from the container dimensions.
Radial gradient fill with center location (0.5, 0.5):
.fill(['black', 'white'],.5,.5)
Additional parameters:
 - opacity - sets an opacity value for gradient;
 - fill area - same as in (UserSpaceOnUse). If fill area is not set, whole container is filled in. If the resulting proportions ratio is not 1:1, the fill will stretch to fill all area (resulting in an ellipse).
 - focal spot location - sets a focal point location as a percentage ratio from container dimensions (0, 1). Focal spot location must not overrun the ellipse borders.
An example of focal spot shape. Focal spot must lay within ellipse borders.
.fill(['black', 'white'],.5,.5, null, 1, 0.23, 0.81)
An example of shape with defined fill area:
.fill(['black', 'white'],.5,.5, anychart.math.rect(0, 0, 400, 400), 1,.5,.7)
Image fill
To fill an element with an image you need to pass the following settings: object with the image source and fill mode. Available fill modes are listed in enum.
 src: '//',
 mode: acgraph.vector.ImageFillMode.TILE

Understanding Aging and Scavenging features in Windows 2000 DNS
- Prerequisites for Aging/Scavenging
- Aging/Scavenging Terminology
- When Scavenging Can Start
- Example of the Aging/Scavenging Process for a Sample Record
Learn about aging and scavenging features of Windows 2000 DNS servers and introduce you to a new terminology.
Windows 2000 DNS servers support aging and scavenging features. These features are provided as a mechanism for performing cleanup and removal of stale resource records (RRs), which can accumulate in zone data over time.
With dynamic update, RRs are automatically added to zones when computers start on the network. However, in some cases, they are not automatically removed when computers leave the network. For example, if a computer registers its own host (A) RR at startup and is later improperly disconnected from the network, its host (A) RR might not be deleted. If your network has mobile users and computers, this situation can occur frequently.
If left unmanaged, the presence of stale RRs in zone data might cause some problems. The following are examples:
If a large number of stale RRs remain in server zones, they can eventually take up server disk space and cause unnecessarily long zone transfers.
DNS servers loading zones with stale RRs might use outdated information to answer client queries, potentially causing the clients to experience name resolution problems on the network.
The accumulation of stale RRs at the DNS server can degrade its performance and responsiveness.
In some cases, the presence of a stale RR in a zone could prevent a DNS domain name from being used by another computer or host device.
To solve these problems, the DNS Server service has the following features:
Time stamping, based on the current date and time set at the server computer, for any RRs added dynamically to primary-type zones. In addition, time stamps are recorded in standard primary zones where aging/scavenging is enabled.
For RRs that you add manually, a time stamp value of zero is used, indicating that they are not affected by the aging process and can remain without limitation in zone data unless you otherwise change their time stamp or delete them.
Aging of RRs in local data, based on a specified refresh time period, for any eligible zones.
Only primary type zones that are loaded by the DNS Server service are eligible to participate in this process.
Scavenging for any RRs that persist beyond the specified refresh period.
When a Windows 2000 DNS server performs a scavenging operation, it can determine that RRs have aged to the point of becoming stale and remove them from zone data. Servers can be configured to perform recurring scavenging operations automatically, or you can initiate an immediate scavenging operation at the server.
By default, the aging and scavenging mechanism is disabled at Windows 2000 DNS servers. It should be enabled only when all parameters are fully understood. Otherwise, the server could be accidentally configured to delete records that should not be deleted. If a record is accidentally deleted, not only will users fail to resolve queries for that record, but any user can create the record and take ownership of it, even on zones configured for secure dynamic update.
The server uses the contents of each RR-specific time stamp, along with other aging/scavenging properties that you can adjust or configure, to determine when it scavenges records.
Before the aging and scavenging features of Windows 2000 DNS can be used, several conditions must be met:
Scavenging and aging must be enabled both at the DNS server and on the zone.
By default, aging and scavenging of resource records is disabled.
Resource records must either be dynamically added to zones or manually modified for use in aging and scavenging operations.
Typically, only those resource records added dynamically using the DNS dynamic update protocol are subject to aging and scavenging.
You can, however, enable scavenging for other resource records added through non-dynamic means. For records added to zones in this way, either by loading a text-based zone file from another DNS server or by manually adding them to a zone, a time stamp of zero is set. This makes these records ineligible for use in aging/scavenging operations.
In order to change this default, you can administer these records individually, to reset and permit them to use a current (non-zero) time stamp value. This enables these records to become aged and scavenged.
In the case of changing a zone from standard primary to Active Directory-integrated, you might want to enable scavenging of all existing resource records in the zone. To enable aging for all existing resource records in a zone, you can use the AgeAllRecords command, which is available through the dnscmd command-line tool.


Eliminate weapons of mass destruction: Speaker
RSTV Bureau
sumitra_mahajanOn the anniversary of Hiroshima and Nagasaki bombing, Lok Sabha remembered the victims on Wednesday, with Speaker Sumitra Mahajan saying everyone should strive for elimination of weapons of mass destruction.
Wreaking havoc, the United States used its atomic weapon against Hiroshima in Japan on August 6, 1945. Three days later, Nagasaki was bombed.
"Let us re-affirm our resolve to relentlessly strive for the elimination of weapons of mass destruction and to ensure the propagation of peace throughout the world," Mahajan said.
The House observed silence in memory of the victims.
"Even after the passage of nearly seven decades, residents of these cities continue to suffer from the horrendous after effects of nuclear radiations," she said.

Costoluto Genovese Tomato
From Thomas Jefferson Encyclopedia
Common Name: Costoluto Genovese Tomato
Scientific Name: Lycopersicon lycopersicum cv
Description: Tender garden vegetable; Flattened, deeply lobed and scalloped, bright rich red fruits; Soft in texture, juicy and slightly tart
Size: Indeterminate vines; space caged plants 24 to 36 inches apart
Cultural Information: Prefers rich, sweet garden loam and full sun
Historical Notes: The Costoluto Genovese tomato is an Italian heirloom tomato variety. Its heavily lobed and often convoluted shape is indicative of early nineteenth century tomato varieties, but makes an oddity in today's vegetable garden. The Costoluto Genovese's stellar flavor is intense and acidic. Because of its odd shape, this tomato is best for sauces and pastes where the skin is removed.

From a delegate's perspective: Queen's Conference on Philanthropy (QCOP)
Two days later, a dozen speakers and panelists broadened my view on apathy, passion and rage.
Speakers at the sixth annual Queen's Conference on Philanthropy (QCOP) ranged from Canadian Olympic team wrestler Ohenewa Akuffo to former child soldier Michel Chikwanine. Other speakers included Russ McLeod, chief operations director of Me to We, Adil Dhalla, director of culture at the Centre for Social Innovation, Shawn Cheung, founder of Raising the Village.
The conference opened with an odd metaphor: one of the co-chairs, Christie Park, Comm '14, described QCOP as her baby finally being born, after nine months of intensive planning and stressful nights, she added. It was a strangely heartwarming description that bespoke of the organizer's enthusiasm for the weekend.
QCOP, more than anything, appeared from the outset as a labour of love.
Principal Woolf followed with a story about Alfred Bader, a fitting example of a man from meager beginnings and generous heart that has contributed much to the Queen's community.
Social worker and founder of Blueprint for Life Steve Leafloor, ArtSci '83, better known as Bboy Buddha, spoke in an off-the-cuff manner that demanded attention. He was engaging in his raw truthful tone. Interspersed with moments of humour and music reminiscent of the 70s, his golden era of roller dancing, he provoked laughter from the audience.
On a more solemn note, he recalled how his own personal experience of bullying prompted his teenage delinquency and drug abuse.
At 16 years old, he stood at four foot seven. Bruises coloured the entirety of his arms, while taunts were thrown as he was stuffed into the depths of trashcans. Anger and rage quickly spiraled into robberies and drug usage. That was before he discovered dance.
Dance ultimately saved him, allowing him a way to express his frustrations.
While some in the audience were moved to tears, it was the travel stories up north to remote Inuit communities that were the most touching. In a span of five days, he flipped regular programming into a dance intensive from the hours of 9 to 5 p.m.
Dance becomes a new mode of uplifting spirits. Dance also became the universal language, transcending language barriers between English and Inuit. He explained that children he encountered had often faced traumatic experiences, whether it was a recent suicide in the community or family abuse.
With his overwhelming positivity and devotion to helping others, speakers like Leafloor represent life as an opportunity to effect change.
Speakers came from all walks of life, whether the corporate or non-profit sector, and emphasized an underlining message that money is not the only means of philanthropy. Striving to effect change can come in other forms beyond the typical donation.
Furthermore, speakers shared various other stories of the impact of storytelling, sometimes travel, but always personal transformation. It was an invigorating weekend that contrasted with the bleak and cold weather outside.
A conference wouldn't be complete without a challenge and this year saw the addition of a new way to engage delegates in a "pay it forward" experience. Divided into randomized team, we were asked to think of an impactful and positive way to spend 10 dollars in a hour and a half.
Teams showcased ingenuity by delivering free gifts on the streets: flowers, candy and hot chocolate with caring notes. Others left mittens with a note attached, encouraging the finder to do a good deed in return. The time constraint and the reluctance of some people to accept gifts from total strangers proved challenging for some. To the typical person, not used to a random kind act, polite rejection was the common response. Perseverance was key. One group mustered the strength to push a stuck car to safety – showing good deeds aren't based on money.
At just over one hundred dollars, the conference's registration fee is cheaper than most. QCOP offers an invigorating way to perceive the world from corporate to grassroot approaches, but more importantly emphasizes the importance of adding generosity and empathy to one's everyday life.

Rock attracts interest in Temora
21 March 2012
An outcrop of rocks in a farm paddock near the New South Wales town of Temora which provides the benchmark for geochronology investigations around the world will itself be the subject of analysis.
The rocks contain tiny zircon crystals, known as the TEMORA reference and are used by more than 100 geochemical and geochronology laboratories around the world, including in Geoscience Australia's Sensitive High Resolution Ion MicroProbe, or SHRIMP.
Now the University of Melbourne School of Earth Sciences is supporting an Honours thesis project to investigate the source of the TEMORA reference material in detail.
The researchers will consider whether the rock is as uniform as the analyses imply, why it is such a good source of the reference material for calibrating the age and geochemical composition of other rocks and if there is even better reference material nearby.
The project will include detailed geological mapping, petrographic studies and geochemical analysis of the original site and nearby granitic outcrops to assess the overall uniformity of the rock and consider what makes the rock so special.
Geoscience Australia is the custodian of the reference material extracted from the rock and its Geochronology Laboratory will support the investigation by assisting with field work and sampling and analytical work.
The Geochronology Section leader at Geoscience Australia, Dr Keith Sircombe, said the research is expected to result in further improvement in analytical processes and in the precision and accuracy of pre-competitive data provided to government agencies, resource exploration companies, researchers and the public.
"Despite its excellent international reputation, the source of the TEMORA reference material has never been examined in detail and the honours project investigation is expected to give new insights into its future applications," Dr Sircombe said.
"The original reference material is a great example of scientific serendipity. It was discovered completely by accident and was almost overlooked for sampling. It will be very exciting to see what other discoveries the team from Melbourne can make," he said.

cout< ctr++;
 Count(num);
 }
 }
 void main()
 {
 Count(ctr);
 return;
 }
 The static integer 'ctr' means that 'ctr' is declared once (the first time the function is called), but its value is used by subsequent calls to the function. It is like a global variable which only Count can see. As you can see, we only call Count once. It keeps on calling itself until a certain condition is met (in our case, when 'ctr' reaches the value of 'num'). So, when we, the programmer, call Count for the first time, we have to set it up. We give it a condition to meet, in our case the number 10. If we wanted it to count to 20, we would pass '20' to Count when we call it. Right, let's summarise that:
 The programmer only calls a recursive function once. The first call (made by the programmer) tends to 'initialise' the function, telling it what to do and what conditions are needed to stop calling itself.
 Well, I'm glad that's out the way. On with our code. Now, let's look at the function CreateNode. As the name suggests, this creates nodes. If only it were that simple :) As this function is recursive, not only does it 'create a node', but by calling itself, it creates the whole quadtree! We only need to call the function CreateNode once, and it does all the hard work. The format for CreateNode is as follows:
 void CreateNode(unsigned int Bounding[4],unsigned int ParentID,
 unsigned int NodeID)
 This function returns nothing. Nil. Void. If you want, you could make it return something like a BOOL for error checking, but for this tutorial, I know the code works, so we'll leave it as 'void' ;). CreateNode takes 3 parameters. The first is the bounding coordinate for the node. These bounding coordinates are index values for the grid/terrain. They are in the following order. Top-left, top-right, bottom-left, bottom-right. The next value is the ID (index) for the node's parent. Last, but by no means least, is the ID (index) for the node. As I said above, when we, the programmer, call CreateNode, we need to initialise it. As the first node is the 'root', we need to set the parameters for the root. The bounding coordinates for the root are that of the whole terrain. In our case, they would be as follows: (0,0,0) (16,0,0) (0,0,16) (16,0,16). The only problem with that is that we just blurted some vertex data. Bounding[4] uses vertex indexes, so we need to find the indexes for the terrain. Put that calculator away, as I have done the work for you:
 In a 2D array extending in the x/z plane with height values of '0' (i.e. our grid), to find the top left, we use the following equation:
 quadcode2.gif
 Wow, that'll get your head scratching. Don't get too cocky, as that was the easy bit. To find the top-right, we use the following equation:
 quadcode3.gif
 Easy, easy... Now let's try the bottom-left:
 quadcode4.gif
 And now the bottom-right:
 quadcode5.gif
 The mathematics isn't hard, but if you're having trouble understanding it, then just plot a grid on some paper (or better yet, squared paper), and step through it. Now we're ready to call CreateNode:
 unsigned int uiBoundingCoordinates[] =
 {0,GridWidth,(GridHeight*(GridWidth+1)),
 ((GridHeight)*(GridWidth+1))+GridWidth};
 CreateNode(uiBoundingCoordinates,0,0);
 What we have done is set up the root node. The root node has the bounding box described above, no parent (so a parent ID of 0), and its ID is 0, i.e. the first element in our quadtree array. We are now prepared to walk through the CreateNode code.
 void CreateNode(unsigned int Bounding[4],unsigned int ParentID,
 unsigned int NodeID)
 {
 static unsigned int TotalTreeID = 0;
 unsigned int uiNodeType;
 unsigned int uiWidth,uiHeight;
 Ok, the static unsigned int 'TotalTreeID' holds the current number of nodes. We use this later on to assign the nodes children their IDs. The unsigned int uiNodeType holds the node's type, either a leaf (LEAF_TYPE) or a node (NODE_TYPE). The unsigned ints uiWidth and uiHeight will hold the width and height of the node. As we are passed just bounding coordinates, we don't actually know the dimensions of the node. We use the uiWidth and uiHeight to tell whether the node is a leaf or node. Now we need to get the width and height from the bounding coordinates:
 uiWidth = fVerts[(Bounding[1]*3)] - fVerts[(Bounding[0]*3)];
 uiHeight = fVerts[(Bounding[2]*3)+2] - fVerts[(Bounding[0]*3)+2];
 This assumes fVerts is an array containing a list of vertices, which build up our grid. As a vertex contains 3 parts, x, y and z, each vertex in the array will occupy 3 elements. Normally, if we have an index of value 3, it would point to the third element. But... as each vertex occupies 3 elements, and index of 3 would point to the third element, i.e. Vertex 0's Z component.
 quadfig14.gif
 Figure 14
 As you can see, an index of 0 points to element[0]. Element [0] is Vertex 0's X component. Element 3 is Vertex 1's X component. This is all very nice, but our indices are wrong, right? Surely if Bounding[0] was '3', it wouldn't point to the third vertex, but the second vertex's X component? Well, we multiply the index by 3 for the vertex's X component, add 1 for the Y component, and add one more for the Z component. so, if we have an index of 3, it's supposed to point to vertex 3. Ok, 3*3 is 9, and the ninth element is vertex 3's x component. So, if we wanted index 3's z component, we would do (3*3)+2, which gives us element 11, vertex 3's Z component! To find the width of the node, we subtract the top-left vertex's X component (remember, x values in our grid go across, so they represent width) from the top-right vertex's X component. And to find the height, we subtract the top-left vertex's Z component (when we say 'height', we mean the depth, but we call it 'height' to make it easier to picture as a 2D grid) from the bottom-left vertex's Z component.
 Now, we said that our leaves are 4x4 triangles. This implies that leaves are 4 triangles wide. As we know the width of the node (stored in uiWidth), if we divide the width by 2 and get a result of 2, then the width is 4, and hence our node is a leaf.
 if(0.5*uiWidth==2)
 {
 uiNodeType = LEAF_TYPE;
 }
 else
 {
 uiNodeType = NODE_TYPE;
 }
 Notice that multiplying by 0.5 is the same as dividing by two. Next, we want a pointer to our node. The reason for this is to save me getting RSI from typing the same thing about 50 times. So, pNodeList contains all our nodes, we just need to select our node:
 NODE *pNode = &pNodeList[NodeID];
 All this means is that instead of doing stuff with our node like so:
 pNodeList[NodeID].uID = Whatever;We can simply do this:
 pNode->uiID = Whatever;The next bit just fills our node with values we have already discussed.
 pNode->uiID = NodeID;
 pNode->uiParentID = ParentID;
 pNode->vBoundingCoordinates[0].x = fVerts[(Bounding[0]*3)];
 pNode->vBoundingCoordinates[0].y = fVerts[(Bounding[0]*3)+1];
 pNode->vBoundingCoordinates[0].z = fVerts[(Bounding[0]

An accelerometer at rest relative to the Earth's surface will indicate approximately 1 g upwards (~9.81 m/s^2). This is because any point on the Earth's surface is accelerating upwards relative to the local inertial frame (the frame of a freely falling object near the surface).
Why isn't the accelerometer zero at rest?

Effect Of The Use Of Unprotected And Unprotected Soybeans Groats With Different Ratios On The Performance Of The Fat-Tailed Sheep Ewe. J Riyanto, R Dewanti1, and A K Wati
Animal Husbandry Department, Faculty of Agriculture, Universitas Sebelas Maret, Surakarta, Indonesia
This research aims to determine the appearance of fat-tailed sheep production by providing rations containing protected and unprotected soybean groats. Protection against soybeans groats using 37% formaldehyde solutions as much as 1% of the dry matter of soybeans groats. The use of protection and unprotected soybeans as much as 15% in rations is given for 30 days before and 70 days after birth. The research treatments were P1 = 25% soybean groats protected and 75% soybean groats unprotected, P2 = 50% soybean groats protected and 50% soybean groats unprotected, and P3 = 75% soybean groats protected and 25% soybean groats unprotected. The research variables include initial weight, weight gain, weight gain, feed intake, and feed efficiency of fat-tailed sheep ewe and birth weight of fat-tailed lamb. The results showed that the difference in the ratio of soybean groats protected and unprotected had a significant effect (P> 0.05) on the feed efficiency of the fat-tailed sheep feed and lambs birth weight and did not affect the performance variables of other production (P <0.05). From the results of the average difference test, it appears that the analysis of variance shows that the highest feed efficiency and birth weight results from the use of rations containing soybean protection and without protection with a ratio of 75%: 25%. The conclusion of the study was the use of rations containing 75% protection of soybeans groats and 25% without protection increased feed efficiency rations in fat-tailed sheep for 70 days after birth and increased the birth weight of their offspring.

3) What are the reproductive risks for men who father a child when receiving leflunomide therapy? In particular what is the risk of fathering a child with congenital malformations or other harmful effects on the fetus due to exposure to leflunomide, its active metabolite or 4-trifluoromethylaniline (TFMA)(Brent 1994, 1999)?
The review of the reproductive effects of mutagenic agents consistently indicates the low risk of these agents for reproductive effects in the F1 generation. Leflunomide and its main metabolic product interfere with pyrimidine synthesis but do not have the mutagenic potential that has been demonstrated for proven mutagenic agents. The reproductive risks for men taking leflunomide are related to the properties of the drug, which are primarily related to the interference with DNA synthesis. Even with the potential reduction in DNA synthesis the risks of infertility are remote, unless the individual already has an infertility problem before starting the medication. Since leflunomide does not have mutagenic potential and the minor metabolite, TFMA is in such low concentration, there should be no measurable increase in the risk of genetic disease in the offspring. TFMA, a minor metabolite of leflunomide, accounts for less than 5% of the metabolic products. In a large series of patients receiving leflunomide in therapeutic doses, 25% of the patients had undetectable levels of TFMA. In the remaining 202 patients, plasma concentrations were very low (8.1 +/- 3.0 ng/ml). While TFMA at high concentrations was mutagenic in the Ames test, the HGPRT and cytogenetics tests, it was not positive in an in vivo cytogenetics test, unscheduled DNA synthesis, and the mouse micronucleus test. Thus, the mutagenicity testing of leflunomide and the phamacokinetics would indicate that preconception exposures would represent no measurable genetic risk in exposed populations and a theoretical risk of reducing gonadal cell populations, but not to the extent of affecting fertility at therapeutic exposure levels in humans.

How fast can a Beagle run?
 Beagles have been used for hunting from centuries and the reason behind this is not else than their running speed.Later they were being used for gaming purposes like dog race.They have been developed by breeders to be smaller in size and faster in speed.Running speed of a dog varies dog to dog.It also depends upon the condition,previous training,health and the circumstances in which his running speed is being measured.Beagles are also thought to be bred with Greyhounds to improve their running abilities.Average running speed for a Beagle is considered to be around 25-30 mph or 40-48 km/h.

La Flaca, a weekly known for its scathing ridicule of political, military and church leaders, was one of the first Spanish periodicals to include double-page color lithographs. In "Pobre España" politicians and military figures are shown as scavenging birds that pick at the ravaged and limp personification of Spain. The insatiable vultures recall the eagle that persecuted Prometheus and pecked at his liver after Zeus bound him to a rock. The birds embody the power struggle and social unrest that characterized the decade following la gloriosa – the 1868 revolution that overthrew the Spanish monarch Isabella II and resulted in the Third Carlist War.

FORECASTS OF AIRCRAFT ACTIVITY BY ALTITUDE, WORLD REGION, AND AIRCRAFT TYPE
The level of international air traffic on a world-wide basis is analyzed for the base year of 1975 and forecast for the years of 1980, 1985, and 1990. An econometric model is used to forecast flight activity using regional economic and population data and data on fuel prices and other aircraft operating costs. Other models transform these forecasts into estimates of aircraft flight hours at various altitudes over areas of the globe. A special model was devised which probabilistically assigns flight-hour activity to specific aircraft types in future years as fleet composition changes. The evidence illustrates the prominence of U.S., European, and U.S.-European traffic in total activity. It also indicated the gradual transition to wide-body aircraft and the gradual phasing out of four-engine, narrow-body transports. (Author)

text: Small-molecule organic photovoltaic cells often employ a planar heterojunction (PHJ) geometry where the electron donor and acceptor materials are stacked one on top of the other. The thin-film growth scenario of such PHJs can be very different from the one of a single compound on a bare substrate. We have investigated the growth of PHJs, consisting of two different donor–acceptor pairs, namely, α-sexithiophene (6T)/C60 and 6T/diindenoperylene (DIP) using real-time in situ X-ray scattering. For both donor–acceptor material combinations, we observe that the coherent in-plane crystalline size of the second material strongly correlates with the one of the bottom one, and hence a strong templating effect of the 6T on the material deposited subsequently, indicating a strong interaction between the two materials in the PHJ. Furthermore, a change in the structure of the 6T film during the deposition of the second material was observed, which shows that the deposition of an additional material on top of a templating layer can partially change the crystal structure of the templating film itself.

The Civil Rights Division of the U.S. Department of Justice is committed to protecting the civil rights of all individuals. Asian Americans and Pacific Islanders (AAPIs) have made significant progress in expanding access to opportunity in recent decades. However, discrimination persists, and access to opportunity all too frequently remains elusive. As a result, the Civil Rights Division remains actively involved in the enforcement of civil rights laws in a variety of settings relevant to AAPI communities.
The Civil Rights Division continues to work to ensure that all students have access to equal educational opportunity. On December 2, 2011, the Departments of Justice and Education released two new guidance documents making clear that educators may consider race in carefully constructed plans to promote diversity or, in K-12 education, to reduce racial isolation. The guidance recognizes the learning benefits to students when campuses and schools include students of diverse backgrounds. On May 6, 2011, in conjunction with the Department of Education, the Division issued a letter clarifying school district obligations to enroll students regardless of their, or their parents' or guardians', actual or perceived citizenship or immigration status. The guidance was disseminated nationwide to ensure that undocumented students are able to enroll and participate in school.
The enforcement of the education provision of the Civil Rights Act of 1964 remains a top priority of the Division. In January 2010, the Division announced a settlement agreement with the School District of Philadelphia to resolve an investigation into a complaint of race, color and/or national origin-based harassment of Asian students at South Philadelphia High School, following the attack of 30 Asian students, approximately 13 of whom were sent to the emergency room. Schools have an obligation to ensure a safe learning environment for everyone and we will continue to use all of the tools in our law enforcement arsenal to ensure that all students can go to school without fearing harassment.
Language barriers continue to present challenges for AAPI communities in a variety of settings. Since January 2009, the Division has opened 22 new investigations to determine if school districts, and in some instances, entire states, were complying with their obligations to ensure educational opportunities for students with limited English skills. In the voting context, the Division has reached groundbreaking settlements to ensure that citizens get the language assistance they need to cast an informed vote. One example includes the consent decree that the Division has obtained to protect Chinese-speaking voters in Alameda County, California. The Department has also played a lead role in the enforcement of Executive Order 13166, which is designed to ensure that people with limited English skills can meaningfully access a wide array of critical programs and services administered by or funded by the federal government.
Expanding equal employment opportunity has also been an important focus of the Division. The Office of Special Counsel for Immigration Related Unfair Employment Practices (OSC) of the Civil Rights Division enforces the anti-discrimination provision of the Immigration and Nationality Act to ensure that individuals are not being discriminated against based on citizenship or immigration status and national origin with respect to hiring, firing, and recruitment or referral for a fee. Currently, Chinese and Filipino immigrants have one of the highest naturalization rates in the nation, and OSC's work ensures that individuals from these and other communities have equal employment opportunities. Over the past 18 months, OSC has initiated more proceedings and collected more civil monetary penalties than the entire preceding six years combined.
As the son of immigrants, I recognize that many of these challenges are both unique to certain groups but also cut across ethnic, racial, and socioeconomic lines. We continue to celebrate the accomplishment of AAPIs, while addressing emerging challenges in advancing civil rights. The Civil Rights Division is committed to continuing our work with AAPI communities and ensuring that everyone has the opportunity to exercise their civil and constitutional rights.
Thomas E. Perez is the Assistant Attorney General for the Civil Rights Division at the U.S. Department of Justice.
