steps/mm
Grbl needs to know how far each step will take the tool in reality. To calculate steps/mm for an axis of your machine you need to know:
在实际应用中 Grbl 需要知道每一步将会走多远，为了计算 步数/毫米 你需要知道您机器的轴的螺距：
 - The mm per revolution of the lead screw
 - The full steps per revolution of your steppers (typically 200)
 - The microsteps per step of your controller (typically 1, 2, 4, 8, or 16). Tip: Using high microstep values (e.g 16) can reduce your stepper motor torque, so use the lowest that gives you the desired axes resolution and comfortable running properties.
The steps/mm can then be calculated like this:
steps_per_mm = (steps_per_revolution*microsteps)/mm_per_rev
Compute this value for every axis and write these settings to Grbl.
然后 步数/毫米 可以这样计算：步数 = （360°/步距角） x 细分数 / 丝杠螺距
计算每个轴的数值并将这些设置写入 Grbl。
$3 – Step pulse, microseconds
Stepper drivers are rated for a certain minimum step pulse length. Check the data sheet or just try some numbers. You want as short pulses as the stepper drivers can reliably recognize. If the pulses are too long you might run into trouble running the system at high feed rates. Generally something between 5 and 50 microseconds works fine.
步进驱动器额定范围的最小步进脉冲长度。你想作为短脉冲同样能够被步进驱动器可靠地识别。请检查数据表或尝试一些数字。如果脉冲太长，在高进给率运行时您可能会遇到系统故障。一般介于 5 至 50 微秒工作正常。
$4 and $5 – 默认的进给和寻址率 ， 毫米/分钟
This setting sets the default seek(G0) and feed rates(G1,G2,G3) after Grbl powers on and initializes. The seek rate (aka rapids) is used for moving from point A to point B as quickly as possible, usually for traversing into position. The seek rate should be set at the maximum speed your machine can go in any axes movement. The default feed rate usually does not enter into the picture as feed rates will generally be specified in the g-code program, but if not, this default feed rate will be used.
这个设置是在 Grbl 加电并初始化后设置默认寻址（G0）和进给率（G1，G2。G3）。此寻址率（即急速）用于从 A 点尽可能快地移动到 B 点，通常为寻迹到的位置。在任何轴运动中，都应该以最大速度设置寻址率。默认的进给速率一般会在特定的 G 代码程序中通常不随着进给率进入图形。但如果没有，便将使用默认的进给速率。
NOTE: In future releases, the default feed rate will be removed. G-code standards do not have a default feed rate (G1,G2,G3), but error out if there has been no 'F' feed rate command specified. The seek rate (aka rapids) will be updated so users can specify the maximum speed each axes can move, rather than have just one speed that limits all of them.
注意：在未来的版本中，默认的进给速度将被移除。G 代码标准中没有默认进给速度（G1，G2，G3），如果没有"F"进给速度命令指定，则报错。寻址速度（即急速）将被更新，这样用户可以指定每个轴最大可移动速度。
$6 – Step port invert mask, int:binary
Some cnc-stepper controllers needs its high-low inputs inverted for both direction and steps. Signal lines are normally held high or low to signal direction or held high and goes low for a couple of microseconds to signal a step event. To achieve this, Grbl can invert the output bits to accomodate particular needs. The invert mask value is a byte that is xored with the step and direction data before it is sent down the stepping port. That way you can use this both to invert step pulses or to invert one or more of the directions of the axes. The bits in this byte corresponds to the pins assigned to stepping in config.h. Note that bits 0 and 1 are not used for inversion. Per default bits are assigned like this:
#define X_STEP_BIT 2
#define Y_STEP_BIT 3
#define Z_STEP_BIT 4
#define X_DIRECTION_BIT 5
#define Y_DIRECTION_BIT 6
#define Z_DIRECTION_BIT 7
If you wanted to invert the X and Y direction in this setup you would calculate a value by bitshifting like this (in your favorite calculating environment):
> (1<<X_DIRECTION_BIT)|(1<<Y_DIRECTION_BIT)
Which is equal to 96, so issuing this command would invert them:
$6=96
Now when you view the current settings, you should now see this in your invert mask line with the binary representation of the number (bits 5 and 6 should now show a 1 to indicate inversion.)
$6=96 (step port invert mask. int:_PHONE_)
$7 – 步空闲延迟，毫秒
Every time your steppers complete a motion and come to a stop, Grbl will disable the steppers by default. The stepper idle lock time is the time length Grbl will keep the steppers locked before disabling. Depending on the system, you can set this to zero and disable it. On others, you may need 25-50 milliseconds to make sure your axes come to complete stop before disabling. (My machine tends to drift just slightly if I don't have this enabled.) OR, you can always keep your axes enabled at all times by setting this value to the maximum 255 milliseconds. Again, just to repeat, you can keep all axes always enabled by setting $7=255.
每次你的步进电机完成一个动作，并停下来，Grbl 默认会被禁用步进电机。步进电机空闲锁定时间的时间长短 Grbl 会使步进电机保持锁定之前禁用（这段话逻辑有些乱，还没弄明白什么意思）。根据系统的不同，您可以将此项设置为零，并禁用它。在其他系统上，你可能需要 25-50 毫秒，以确保您的轴在完全停止之前禁用。 （如果我没有启用，我的机器就有可能稍微漂移。）或者，你可以通过将此值设置为最大 255 毫秒，来始终保持你的轴在任何时候为启用状态。再次，只要重复，通过设置 $7=255 你可以保持所有轴始终启用。
$8 – 加速度，mm/sec^2
This is the acceleration in mm/second/second. You don't have to understand what that means, suffice it to say that a lower value gives smooooother acceleration while a higher value yields tighter moves and reach the desired feedrates much quicker. In technical terms, this is the point to point acceleration of your machine, independent of axes. Set this acceleration value as high as your most limiting axes can let you without losing ANY steps. Usually you'd like to give yourself a little buffer, because if you lose steps, Grbl has no idea this has happened (steppers are open-loop control) and will keep going.
$9 – Junction deviation, mm
Cornering junction deviation is used by the acceleration manager to determine how fast it can move through a path. The math is a bit complicated but in general, higher values gives generally faster, possibly jerkier motion. Lower values makes the acceleration manager more careful and will lead to careful and slower cornering. So if you run into problems where your machine tries to take a corner too fast, decrease this value to make it slow down. If you want your machine to move faster through junctions, increase this value to speed it up. For technical people, hit this link to read about Grbl's cornering algorithm, which accounts for both velocity and junction angle with a very simple, efficient, and robust method.
$10 – 弧， mm/segment
Grbl renders circles and arcs by subdividing them into teeny tiny lines. You will probably never need to adjust this value – but

Topographic and hydrologic modelling applied to mineral exploration in Tasmania
thesisposted on 2023-05-27, 17:46 authored by Rice, Peter J
Recent developments in Geographic Information Systems (GIS) technology enable complex modelling of geoscientific data which would not have been practical using manual methods. New techniques have been developed in this study for the statistical analysis of the distribution of topographic lineaments and for hydrologic modelling of stream sediment geochemical data. Topographic lineaments interpreted from artificial illumination of a digital elevation model of Tasmania have be categorised into four types according to persistence, orientation and temporal relationships. Type 1&2 lineaments are the most persistent forming major features that can be traced across Tasmania. Type 3 do not form persistent patterns and Type 4 trend north-south cross cutting other lineaments. The spatial association between Tasmanian mineral occurrences (points) and topographic lineaments (lines) has been analysed using a number of methodologies. Existing methods for testing point line spatial association were found to be unsuitable due to the deleterious effects of mineral occurrence clustering. A new method of Monte Carlo analysis has been developed which, in part, overcomes the effects of clustering. Monte Carlo analysis has been used to test the spatial association of primary copper, gold and tin occurrences across the Tasmanian mainland. Primary copper and tin occurrences have a spatial association with Type 1&2 and Type 3 topographic lineaments and gold occurrences are only associated with Type 1&2 topographic lineaments. A spatial association may also be inferred between tin occurrences and a composite of Type 1,2&3 topographic lineaments inside a zone defined by the interpreted 2 km granite depth contour in northwest Tasmania. The value of stream sediment geochemistry to mineral exploration is significantly increased by accurate determination of lithological and dispersion residuals. Lithological background levels of stream sediment trace elements were determined for each rock type from a point in polygon overlay of sample locations in lithology polygons. The lithological background at each sample site was calculated from a flow accumulation model and subtracted from observed values to produce a lithological residual. The dispersion residual was calculated by subtracting the average lithological residual of all samples upstream from a sample site, weighted by sample watershed area. The lithological residual enhances definition of anomalies by removing gross lithological variation. Dispersion residuals, calculated from the lithological residual, highlight local effects and emphasise subtle variation down stream from major anomalies. Hydrologic modelling has been applied to a stream sediment geochemistry survey from the Natone district in northwest Tasmania. Analysis of the Natone geochemical data using the methodologies developed in this study defines anomalies which are coincident with known mineralisation and geophysical anomalies. The lithological residual extends copper and zinc anomalies from the Upper Stowport Prospect southeast across the Precambrian siltstone-Devonian granite contact indicating an enlarged geochemical anomaly which has not been identified by convent10nal data analysis techniques. In the Chasm Creek catchment previously undetected copper, lend and zinc dispersion residual anomalies are coincident with electromagnetic and magnetic anomalies that are untested by drilling.

The Question:
What is the water temperature at the Mariana Trench—the deepest part of the Pacific Ocean?
The Answer:
When dealing with ocean temperatures it's important to recognize that water temperature generally decreases as you move into deeper water.
The relatively warm surface water of oceans like the Pacific Ocean extends to depths of between 500 and 1,000 feet. Below the surface waters, the temperature drops rapidly, forming a layer called the thermocline.
The thermocline varies in thickness from about 1,000 feet to 3,000 feet. Below this point water cools more slowly. At areas like the Mariana Trench (or the Marianas Trench; both spellings are commonly found) the water temperature ranges from 34-39 degrees F (1-4 degrees C).

Global Tables
Overview and Key Concepts
Global Tables can store numbers, strings, pointers, arrays, FlexScript, bundles or tracked variables. This data can be accessed by any object in the model using the Table class interface. A model may have any number of Global Tables.
Global Tables are accessed from the Toolbox.
Getting and Setting Table Data
Here are some code examples of getting and setting table data.
 Table myTable = Table("GlobalTable1");
 myTable[1][1] = 5;
 myTable[2]["MyCol"] = "Test";
 item.LabelName = myTable[1][2];
 double value = Table("GlobalTable1")[1]["Col 3"];

For more information, see the Table FlexScript API.
Editing the Table
To edit a cell in the table, click the desired cell and begin typing to overwrite all data in the cell, or double click on the cell to select the cell's contents. You can also right-click a cell and select Explore As Table or Explore As Tree and edit the cell's data through there. If the cell has array or bundle data, double-clicking the cell will open a new table window for editing.
Use the arrow keys to navigate between cells. Cells hold number data by default. You can change a cell's data type by right-clicking on the cell and selecting an option under the Assign Data menu. The right-click menu also has options for insert/deleting rows and columns, clearing cell data, and sorting by column.
Other options, like resizing the table, can be found in Properties.
Bundle Data
If the "Use Bundles" checkbox is checked, your table will change internally to use the bundle data type. This means that your table will take significantly less memory. However, there are some limitations. All data in a column must be of one type (number, string, or node) and rows can no longer be named. The data type of a column can be changed by right-clicking in a cell in the column. All of the normal table functions will work with the bundle data type.
Using bundles for your table data is highly recommended for large tables with over 500 rows or columns.
Cell Data Types
Cells in a table can store a variety of different types of data. These include:
 - Numbers: Integer or floating point.
 - Strings: Text like names or sentences.
 - Pointers: References to other nodes or objects. The value displayed is the path to the node/object and will be purple.
 - Arrays: Arrays can have any number of elements. Each element can store a number, string, pointer or array.
 - FlexScript: FlexScript toggled nodes allow you to write code that can that be evaluated using the evaluate() method. For example, Table("GlobalTable1").cell(1, 1).evaluate()
 - Bundles: Data table that stores numbers and strings.
 - Tracked Variables: Tracked variables are often used for statistic collection.
Additionally, a cell can also store a table of data. This can be done regardless of the data stored on the cell. To create a table on a cell, right click on the desired cell and select Explore As Table. This will open a new table window where you can add rows and columns to the cell. If a cell has a table, a small gray triangle will be drawn in the upper right corner of the cell.
Tracked Variable cells will display with a small green triangle in the upper right corner.
If a cell has array or bundle data, double-clicking on the cell will open a table view that can be edited.
Properties Panels
The Global Table uses the following properties panels:

Communicate Through Social Networking
At the heart of Oracle WebCenter Portal is the concept of group participation and social networking, linking users and information together in useful ways. For example:
- Sales people can contribute to reports and planning documents linked to a CRM record.
- Managers can bring together data from enterprise systems with documents in Microsoft Office, and securely share the results with customers and colleagues.
- Users can manage documents and projects in a WebCenter Portal: Spaces, create and edit project documents in a wiki, and send related announcements to space members.
The services that support these group concepts are:
- Activity Graph: Enables users to quickly view the most recent documents, discussions, and announcements in one location. Enables tracking of any kind of activity that the user performs in order to influence results and recommendations from other services.
- Announcements: Offers an effective group communication mechanism for important activities and events.
- Blog: Provides the means for an individual or a community to share personal insights with online audiences. This service supports two types of blogs: personal blogs for individual users, and community blogs that enable members to share their views on a particular topic.
- Comments & Likes:.
- Discussions: Enables community discussions on a set of topics, facilitates quick resolution of issues, and provides a searchable knowledge base.
- Documents: Enables users to display and manage their documents and files in a content repository.
- Events: Provides group calendars to enable users to schedule meetings, appointments, and any other type of team event. Additionally, a dedicated Events page is available to every space where the moderator has enabled the Events service.
- Instant Messaging and Presence: Enables users
to see who in their community is online, and provides instant access
to interaction options, such as sending an instant message, writing a
mail message, and displaying a peer's profile.
- Links: Provides an easy way for users to share their knowledge with others. Often, there are many tasks that require users to remember the relationship between different items. For example, an employee might have to remember where to file their expense reports, and also have to remember where the document describing the rules has been stored. Using Links, users can connect seemingly unrelated items together. In this way, they do not have to rely on memory and new users receive the benefit of their work.
- Lists: Allows users to create and manage all types of lists. This is an extremely powerful capability for users to keep track of meeting action items, open issues, new product or project ideas, project status, and more.
- People Connections: Enables users to quickly assemble their business networks. The People Connections service includes task flows or portlets that show off a user's profile, visualize the user's connections list or network, display all the invitations pending and accepted from others, deliver a whiteboard (often called a wall) to project out relevant information about one's role or self, and provide a means to monitor and manage received and given kudos.
- Polls: Enables any user to take a poll of their constituents and users to gather consensus, get their feedback and make informed decisions. The Polls building environment is a wizard based approach at determining the list of questions with the different responses. At the end of taking a poll, users can be presented with a graph of the results as well so that they can understand the overall results as well.
- Tags: Provides a way for users to mark items that they use infrequently so that they can find them quickly when required. In addition, tagging allows for others to find items based on their own labels instead of a corporate taxonomy. The capability to tag items delivers a better organization of information based on how users really use and label the items, often called a folksonomy. Since tags are directly integrated with searching, users can immediately find what they need.
- Wiki: Provides a means of working simultaneously on documents and sharing ideas, either in the context of communities, or as individuals.

text: In this work, 10 processing type Hungarian tomato gene bank accessions were investigated in a 3-year open-field experiment together with three commercial varieties for quantifying the genotype × environment interaction for their total soluble solids, total acid, dry matter, lycopene, total polyphenol content and antioxidant activity. Results showed remarkable differences of accessions in phytonutrient content over the 3 years (environments). Genotype main effect plus genotype × environment interaction biplots were created for the visualization of the best performing samples and of their relation to a theoretical best variety. Obovate fruit-shaped accessions (especially RCAT031257 and RCAT060349) reached outstanding nutritional results in every environment. According to extremities in weather conditions, two landraces (RCAT060348 and RCAT060349) with higher drought tolerance, and two (RCAT031257 and RCAT029837) less prone to excessive rainfalls were identified. The results can contribute to the enrichment of tomato nutritional phenotypic data banks, facilitating the utilization of gene bank accessions in genomic studies.


Miles Guo: chicken prices in China will soar. China is facing food shortage crisis
China has reported at least two million pigs have died as a result of African swine fever in China. The pork prices are soaring in mainland China. As a result, many Chinese people are looking to buy other meats such as chicken, beef, and mutton. This led to another rise in the wholesale price of meat nationwide. The price of pork rose 11% to 51.21 RMB from 46.13 RMB per kilogram last week from October 14 to October 20, and the increase was another 2.4%, which was closer to the price of beef and mutton, which rose 1.2% and 1.7% to 65.81 RMB, 62.73 RMB per kilogram respectively.
Blue indicate: pork | Orange indicate: chicken | Graph: Ministry of Agriculture
According to the Ministry of Agriculture's national wholesale market price information system, the prices of pork, mutton, beef, eggs and chicken, which were monitored from October 18 to October 24, rose 144.8%, 19.0%, 16.2%, 23.1% and 30.7%, respectively, compared with the same period last year.
On top of that, Chinese grain producers have been hit by what can only be called a plague of a dangerous pest called "Fall Armyworms," that devastates rice and other grain crops. The combination hitting China as its leaders are in the midst of an escalating major trade war with the United State.
The food shortage, economic and financial pressures in China will pose a threat to communist party leaders and their regime. Because in the past Chinese history, when there was a shortage of food and the domestic economy was severely damaged, the Chinese people would stand up and overthrow the political party and start the so-called revolutionary movement. This is exactly what happened in 1911 when the Chinese people had a problem with food shortage, and immediately the South was in turmoil. This is why Beijing is now doing whatever it can to quell the Hong Kong issue, or their regime will be threatened.

text: The aim of this study was to investigate the cholesterol removal capacity of seven metal-organic frameworks (MOF) and to compare with active carbon as adsorbents, and with aqueous beta-cyclodextrine complexation removal technique. There were slight color differences in the oil samples after the treatments. The lowest free fatty acidities (0.13% and 0.13% linoleic acid) and peroxide values (21.07 and 23.50 meqO(2)/kg) were measured in aluminum-MOF (Al-MOF) and titanium-MOF (Ti-MOF) treated samples when compared to control sample (0.15%, and 27.62 meqO(2)/kg). Cholesterol reduction ratios of the Al-MOF treated sample (27.45%) and Ti-MOF treated sample (26.27%) were higher among all adsorbent treatments, but lower than that of the beta-cyclodextrine aqueous complexation technique (33.07%). Further experiments with Al-MOF and Ti-MOF showed that when adsorbent addition level increased to 3.0%, removed cholesterol content increased. Likewise, when treatment times extended to 180 min, more cholesterol was removed. But, the removed cholesterol contents at 100 degrees C and 30 degrees C treatment temperatures were lower than that of at 50 degrees C treatment temperature. Further experiments with butter and sheep tail tallow showed that Al-MOF was quite effective as an adsorbent to remove cholesterol. This study proves the great potential of MOF to remove cholesterol selectively from oil/fat by adsorption principle.

Although in the past great attention has been devoted to coastal stabilization, the effect of aquatic vegetation on wave characteristics (damping and retardance etc) is still not well known. In this context an experimental study was performed in an irregular wave flume to explore the effect of reeds (phragmites australis) on wave damping and retardance. Further for a given vegetated area the effect of wave characteristics (i.e. wave height, wave period and wave steepness) on wave damping and retardance were discussed. Real reeds (phragmites australis) with diameter less than 5 mm were employed throughout the experiments for the emergent case. A dimensionless number was introduced to characterize both the vegetated area magnitude and the effect of the vegetation on wave damping and retardance.

text: Optical interferometry enables highly accurate non-contact displacement measurement. The optical phase ambiguity needs to be resolved for absolute distance ranging. In controlled laboratory conditions and for short distances it is possible to track a non-interrupted displacement from a reference position to a remote target. With large distances covered in field applications this may not be feasible, e.g. in structure monitoring, large scale industrial manufacturing or aerospace navigation and attitude control. We use an optical frequency comb source to explore absolute distance measurement by means of a combined spectral and multi-wavelength homodyne interferometry. This relaxes the absolute distance ambiguity to a few tens of centimeters, covered by simpler electronic distance meters, while maintaining highly accurate optical phase measuring capability. A virtually imaged phased array spectrometer records a spatially dispersed interferogram in a single exposure and allows for resolving the modes of our near infrared comb source with 1 GHz mode separation. This enables measurements with direct traceability of the atomic clock referenced comb source. We observed agreement within 500 nm in comparison with a commercial displacement interferometer for target distances up to 50 m. Furthermore, we report on current work toward applicability in less controlled conditions. A filter cavity decimates the comb source to an increased mode separation larger than 20 GHz. A simple grating spectrometer then allows to record mode-resolved interferograms.

As part of a study on prevalence and cognitive effects of tobacco use, women with schizophrenia, bipolar disorder and depression were assessed for cognitive functioning using an information questionnaire derived from the Indian Post Graduate Institute Battery of Brain Dysfunction (PGIBBD) and the Trail Making Tests (TMT) A and B. The community dwelling women were clinically diagnosed and recruited from the outpatient department of a free tertiary care teaching hospital in India. The sample consisted of 321 women, 141 with schizophrenia (SZ), 80 with Bipolar Disorder (BD) and 100 with Recurrent Depressive Disorder (RDD). Tobacco users answered statistically significantly fewer questions on the PGIBBD Information Questionnaire. Users also took significantly more time to complete both TMT-A and TMT-B. Age, years of schooling and tobacco use were all significant co-variates for performance on cognitive tests. Tobacco users had lower motor speed and lesser visual scanning, poorer flexibility of thinking and working memory. Women with schizophrenia performed the worst. Tobacco use may exacerbate the cognitive dysfunction associated with major mental illnesses among women.Copyright © 2020 Elsevier B.V. All rights reserved.

In this video, a bird is plucking fur from sleeping Labrador Retriever, Maple.
The owners of the dog said that they had filmed at least three times that the bird flew down to pluck fur from their sleeping dog. It lasts only a few minutes, and then the bird flies back to pad her nest with the fur.
The dog occasionally wakes up, but doesn't seem to mind. This may not be a common practice for birds, but we hope it's somehow a symbiotic relationship.

The LEMON Parser Generator
The Lemon program is an LALR(1) parser generator. It takes a context free grammar and converts it into a subroutine that will parse a file using that grammar.
Lemon is similar to the much more famous programs "YACC" and "BISON". But lemon is not compatible with either yacc or bison. There are several important differences:
The complete source code to the lemon parser generator is contained in two files. The file lemon.c is the parser generator program itself. A separate file lempar.c is the template for the parser subroutine that lemon generates. Documentation on lemon is also available.
To see an example of how to use lemon, see the source code to the SQLite database engine. Lemon is maintained as part of the SQLite project.

European consumption experts today called for a new research policy on sustainable food consumption. Facing recent food crises around the globe, European food research should set new priorities, advocated researchers and policy makers from all over Europe. More than 100 experts have jointly developed a "Research Agenda for Sustainable Food Consumption in Europe", which sets the stage for pressing challenges to be addressed in coming years. Hot topics on the agenda include sustainable diets such as the reduction of meat consumption and animal-based products as well as sustainable food supply chains, e.g., strengthening local food systems. In light of the current hunger crisis in East Africa, reducing global food inequality gains a new and special significance.
"Going forward towards more sustainable food consumption requires a sound prioritisation of the relevant topics involved", states Gerd Scholl, scientist at the Berlin-based Institute for Ecological Economy Research (IÖW). "The new research agenda is the result of collaboration between food and consumption specialists from all over Europe. It offers a strategic and comprehensive approach for designing an innovative research policy in this domain."
The research agenda has been developed by the European consortium CORPUS, which connects researchers and policy makers from all over Europe, in order to work jointly on sustainable consumption policies. The agenda results from a series of three workshops addressing, amongst other topics, current food trends, policy instruments and future visions for sustainable food. "Such a close cooperation on this topic is unique", says Gerd Scholl. "The expertise of the different professionals involved gives weight to the topics listed in the common research agenda. We call on European research policy to further endorse strategic research on sustainable food consumption."
The consortium "CORPUS – Enhancing the connectivity between research and policy-making in sustainable consumption" is funded within the EU Seventh Framework programme. It aims to experiment with, and develop, new integrative modalities of knowledge brokerage on sustainable consumption policies. In addition to sustainable food, the consortium addresses the domains of sustainable mobility and sustainable housing. The website _URL_ has been established as a platform for knowledge exchange and professional networking. The documentation of the food workshop series is available at: _URL_

How to turn on vox function in analog and digital radio? You can turn on it by software, some radios can be turned on by the keyboard.
What is VOX, and how does it work?
VOX stands for "Voice Operated Exchange". To put it in simple terms, that just means voice-activated transmission. With this mode switched on, the two-way radio is always listening out for human speech. It does this by detecting tiny changes in the air pressure. It then automatically starts transmitting when someone starts talking. Once you stop, the handset will stop transmitting, so that you can hear the other person's reply.
How to turn on vox function in digital radio?
Taking RT3s as an example:
In Menu Item, please check the vox function to make sure it appears in the Utilities- Radio setting of walkie talkie.

Hydrogen Hustle: Report Exposes Dirty Energy Wish-List to Co-opt Hydrogen Funding
WASHINGTON – Today, Friends of the Earth released a report that details how dirty energy industries are seeking to manipulate the 45V hydrogen production tax credit for their own financial gain. Hydrogen Hustle provides a roadmap of key polluter demands to undermine hydrogen emissions requirements. The new report comes at the start of a three-day public hearing on the credit sponsored by the Treasury and IRS.
- Big Oil, major utilities companies and nuclear giants are undermining the Biden Administration's modest steps towards a "three pillars" approach to hydrogen.
- Fossil fuel companies are joining forces with factory farms and landfills to demand that dirty fossil hydrogen be allowed to claim the highest tier of the credit.
- Prominent Blue State governors, including Jay Inslee and Gavin Newson, are using their credentials as climate leaders to weaken the integrity of the 45V credit.
- Big Oil is attempting to "lock-in" the Department of Energy's low-ball estimate for methane leakage,
- Methane gas "certifiers" like Project Canary are siding with Big Oil to further weaken the Biden Administration's already flawed approach to emissions modeling.
"If Big Oil and other polluters get their way, then the hydrogen credit will become yet another fossil fuel cash grab," said Sarah Lutz, Climate Campaigner at Friends of the Earth and author of the report. "It is more important than ever for the Biden Administration to stand firm with a strong, science-driven approach."
Earlier this year, Friends of the Earth led over 75 environmental and justice-oriented groups in a letter to the Internal Revenue Service and Treasury Department, calling on them to ensure that dirty energy industries like fossil fuels, nuclear, wood, and methane biogas can't obscure their true emissions. In 2023, FoE first sounded the alarm on Big Oil's campaign to weaken the hydrogen tax credit. Now that the Biden Administration has released its draft guidance, the Hydrogen Hustle report provides a Cliff Notes guide to how polluters' lobbying has adapted and on the environmental cost of potential concessions.

Automation playbooks can be triggered by several events in the life cycle of an external alert:
- When an external alert is ingested
- When an external alert validation state changes
- When an external alert hasn't been correlated for 24 hours
These triggers enable powerful workflows that allow your team to best defend your organization.
What automation actions affect the state of external alerts?
A number of automation actions can affect the state of external alerts. These include:
- Comment on Alert in Source Platform
- Update State of Alert in Source Platform
You can find the complete list of actions in your Red Canary portal.
What are examples of automation that begins with external alerts?
Notifying your team when a high-severity alert is ingested from a network security product
You can use Red Canary to fulfill basic SIEM and SOAR use cases, such as notifying your team when any of your network security products identifies what it reports as a high-severity threat:
Notifying your team when an alert could not be correlated to endpoint and process data within 24 hours
You may want to notify your team if Red Canary has been unable to correlate certain alerts with endpoint or process activity within 24 hours so you can investigate that alert yourself.
Automatically closing low / informational severity alerts for certain noisy platforms
Many alert sources generate a high volume of alerts with low severities and do not provide the ability to automatically close or adjudicate those alerts. You can use Red Canary to better operationalize those platforms:
By triggering playbooks that:
- Add a comment on the alert (in the underlying platform) that "This alert is being automatically closed because it is high volume / low value" using the Comment on Alert in Source Platform action.
- Close the alert (in the underlying platform) using the Update State of Alert in Source Platform action.

New Capabilities are introduced in the AppFramework as a part of AppStudio 2.0. These capabilities are not provided natively by Qt. Following capabilities are currently in beta
These capabilities are currently in Beta. What does that mean?
What it means is that we are looking forward to your feedback, the use cases, what you like and what you want us to improve upon. It also means that if you choose to implement these plugins in Production App. Future changes may affect your app may require additional changes to support these functionalities in your app.
1. Local Notification - This is a new plugin added to the AppFramework. It provides developers the ability to implement in-app notification to end users such as an alert, message or geotification. When the Local Notification gets triggered on the client device the Notification icon appears in the Notification bar which is same as the application icon. The Notification icon cannot be customized or modified. Users may choose to have one or multiple notifications within the app. Every notification scheduled has a corresponding id available to distinguish between multiple Local Notifications.
Note:- An app running within Player or AppStudio Desktop (AppRun) will show the notification icon of Player or AppRun respectively when triggered.
How to implement Local Notification in an AppStudio App?
- Use the following import statement
import ArcGIS.AppFramework.Notifications.Local 1.0
- Enable the "Local Notification" capability within the AppSettings of the App
- Use the component "LocalNotification" which takes three input parameters to schedule a notification
- Title – The title of the message
- Message – The description of the message
- Time (in seconds)- Time after which the notification will be triggered on the end user device.
- bool supported (read only)- Returns a boolean if the device supports local notification.
Note: This property is supported on Android API 19+ versions.
- object schedule(string title, string message, int timeInSeconds) - returns a Variant object which is id of the scheduled notification
- Title - The title of the message as string value
- Message -The description of the message as string value
- Time (in seconds) -Time after which the notification will appear on the end user device as int
For e.g. 5 seconds means the notification will be triggered in 5 second
var id = notification.schedule(title, message, duration)
- bool clear(object id) -This method will clear the pending notification from the list of scheduled notifications
- object id - The id of the notification to be clear.
- Returns bool - Indicates whether the notification is cleared from the list of scheduled notifications.
bool success = notification.clear(id)
Note: It will return false for invalid inputs and for notifications which have already triggered.
- void clearAll() - This method clears all the pending (yet to be triggered) and active (already triggered) notifications along with badge numbers for iOS apps.
- triggered(object id) - This signal is emitted when the local notification is triggered.
- object id-It takes an id of the scheduled notification.
2. Vibration (Singleton) - New plugin added in AppFramework with AppStudio 2.0 version. This allows developers to enable vibration within an app. It is a non visual feedback or alert. Common use cases to provide vibration are to indicate an event such a message received or finished creating a model making a network request or just an alert etc.
Note: Currently, there is no way to provide number of seconds as an input for it to vibrate. On android device, it will vibrate for 1 second and on iOS it will use the system default.
How to implement Vibration in the AppStudio App?
- Use the following import statement
import ArcGIS.AppFramework.Notifications 1.0
- Enable the Vibration capability within the AppSettings of the App
- Call the Vibration.vibrate()
- bool supported - Returns a boolean value indicating whether your device supports vibration or not.
- void vibrate() - Method call to initiate a vibration on the client device from the app. The device will continue to vibrate for system default vibration settings (in seconds) or until the app is closed.
3. Background Location - New capability has been introduced to AppStudio 2.0 which allows the apps to use location data in background mode. Some of the common use cases using this capability are logging location data using position source, or trigger a notification, geo-fencing etc. This capability is currently available for mobile platforms only as this is already supported on desktop.
How to implement Background Location in the AppStudio App?
- Enable the Background Location capability in AppSettings of the App
You can monitor the state of the application using the following property
4. Promises - Often while creating your apps, you may want to make something happen after something else is done. You may want to want to make an asynchronous request and perform something on completion of the request. Or you may simply want to execute set of operations in a particular sequence. Promises can be used to manage such asynchronous computation, allowing for separate processes to continue in parallel.
Promises are a pattern that helps with one particular kind of asynchronous programming: a function (or method) that returns a single result asynchronously. One popular way of receiving such a result is via a callback. Promises provide a simpler alternative for executing, composing, and managing asynchronous operations when compared to traditional callback-based approaches. The Promise object represents the eventual completion (or failure) of an asynchronous operation, and its resulting value.
A promise can be in one of 3 states:
- Pending - the promise's outcome hasn't yet been determined, because the asynchronous operation that will produce its result hasn't completed yet.
- Fulfilled - the asynchronous operation has completed, and the promise has a value.
- Rejected - the asynchronous operation failed, and the promise will never be fulfilled. In the rejected state, a promise has a reason that indicates why the operation failed.
When a promise is pending, it can transition to the fulfilled or rejected state. Once a promise is fulfilled or rejected, however, it will never transition to any other state, and its value or failure reason will not change.


Edden Hammons
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Edden Hammons (born 28 Feb 1875[1] Webster County, West Virginia, died 7 September 1955[2] ) was an American fiddler from West Virginia. He was known for his idiosyncratic style, creativity, and the many (often exaggerated) folkloric tales about him.[3]
Edden Hammons was born to Jesse Hammons and Nancy Hicks on 28 February 1875 at Williams River in Webster County, West Virginia. He was the youngest in a family of seven. His three brothers (Paris, Peter, and Cornelius), as well as his father, played the fiddle. Edden took up the fiddle at an early age, playing on a fiddle made out of a gourd that his father made for him. His family was known for its musicians, woodsmen, and hunters.[3]
Edden progressed in his fiddle playing and soon obtained a store-bought fiddle. There are several different stories about this. In one, a friend of Edden's father asked Edden to play him a tune. Edden took out his gourd-fiddle and played for the man. Afterwards, the man was so impressed that he gave Edden his own fiddle. Another story refers to when a renowned fiddler named Bernard "Burn" Hamrick was playing for a local dance. After he finished playing, Edden's father asked Burn if Edden could play a few tunes on his fiddle. Burn agreed to let Edden play his fiddle, and was so discouraged afterwards by Edden's superior ability that he let him keep the fiddle. Whatever the story may have really been, it is sure that Edden received a nicer fiddle that his original one, and started to become well known as a fiddle player in his area.[3]
In his home, Edden was spoiled and spared from chores and work. These qualities would follow him into his adult life. A popular example among the Hammons family of Edden's distaste of work is shortly after his first marriage in 1892. His wife asked Edden to stop playing the fiddle, get a job, and support a family. Edden was quoted as saying "Pon [sic] my honor, I'll lay my fiddle down for no damn woman".[3] The two separated and were legally divorced in 1897. 10 days after the divorce, Edden married his second wife, Elizabeth Shaffer (despite pleas from Elizabeth's family members for her to not marry Edden). The two raised seven children and remained married until Elizabeth's death in 1954.[3]
Edden's family lived somewhat nomadically, moving from one place to another usually twice a year. Edden still rarely worked during these times. He supported his family through hunting, fishing, farming, moonshining and other odd jobs. His daughter, Emma Hammons, recalls that "[h]e whittled axe handles, he played for dances, different things. He picked up money that way. Ginseng, he'd get money that way. It was against the law but he would kill squirrels, turkeys and sell them, or fish - he always had a couple dollars in his pocket somehow".[3]
Edden continued his fiddle playing throughout his adult life. At this point he was regarded as one of the best fiddlers from West Virginia. He won many fiddle contests. People would visit at odd hours just to hear him play, and on some occasions, people would have him play music over the phone while the neighborhood listened in. Other anecdotes appear from this era, such as how Edden would show up somewhere to play music, and would carry his fiddle in a flour sack (with the flour still inside it). His nephew, Currence, recalls when "[Edden] just walked over to the corner and picked up the flour poke and they all got to looking to what he was getting. He pulled that old fiddle out and flour all over it. He dusted it off, blowed it off, you know. Some of them went to laughing and hollering about that flour. 'Upon my honor,' Edden said, 'that's just as good as the best cases every made,' he said, 'that flour makes her play good.'" [3]
On 7 September 1955, Hammons died of coronary thrombosis at Renick in Pocahontas County, West Virginia.[4] His death record cites his occupation as fiddler.[5]
To this day, Edden Hammons is still a very well respected fiddler. He has recorded many solo fiddle tunes on two compilations of his music.
Although occasionally accompanied by his son, James, Hammons typically played alone. Consequently, he was able to play some tunes in odd time signatures, play certain parts as many times as he found fit, and change the tempo at his will without having to worry about throwing off a band. He was also known for playing several variations of the same melody within a tune, adding a lot of ornamentation, and occasionally tagging on a few extra beats to some parts (such as "Big Fancy").
Edden is one of the few, if not the only, sources of many traditional songs that are popular today. These include "Shaking Off the Acorns", "Sandy Boys", "Big Fancy", and "Old Greasy Coat". His influence is still widespread among old-time fiddlers and other musicians within the old-time genre.
In August 1947, Louis Chappell recorded 52 tunes by Edden Hammons. These were released as two separate LPs. The first was "The Edden Hammons Collection, Volume One", which contained 15 of these recordings. Some of these tunes included "Washington's March", "Shaking Off the Acorns", and "Fine Times At Our House".[3] The second release was a two-disc set called "The Edden Hammons Collection, Volume Two", which contained more recorded songs from the same session. This release contained such tunes as "Birdy", "Jake's Got the Bellyache", and "Big Hoedown". Both of these LP's were released in 1984

Dryopteris clintoniana (Dryopteris cristata var. clintoniana)
Clinton's woodfern originated as a hybrid of Goldie's fern and crested woodfern, and its characteristics are mostly intermediate between the two parents. The fertile fronds of Clinton's woodfern are taller, narrower, and more upright than its sterile fronds, but the difference is less pronounced than it is in crested woodfern. Like crested woodfern, Clinton's woodfern's lowest leaflets are broadly triangular. The fronds are wider than crested woodfern fronds, but narrower than Goldie's fern fronds.

Measuring the gain in income from migration is complicated by non-random selection of migrants from the general population, making it hard to obtain an appropriate comparison group of non-migrants.
This paper uses a migrant lottery to overcome this problem, providing an experimental measure of the income gains from migration. New Zealand allows a quota of Tongans to immigrate each year with a lottery used to choose amongst the excess number of applicants. A unique survey conducted by the authors in these two countries allows experimental estimates of the income gains from migration to be obtained by comparing the incomes of migrants to those who applied to migrate, but whose names were not drawn in the lottery, after allowing for the effect of noncompliance among some of those whose names were drawn.
We also conducted a survey of individuals who did not apply for the lottery. Comparing this non-applicant group to the migrants enables assessment of the degree to which non-experimental methods can provide an unbiased estimate of the income gains from migration.
We find evidence of migrants being positively selected in terms of both observed and unobserved skills. As a result, non-experimental methods are found to overstate the gains from migration, by 9 to 82 percent. A good instrumental variable works best, while difference-in-differences and bias-adjusted propensity-score matching also perform comparatively well.

Now, odours can be rated on scale of pleasantness!Published On: Mon, Oct 3rd, 2011 | Neurobiology | By BioNews
A new research has claimed that odours can be rated on a scale of pleasantness, which turns out to be an organizing principle for the way humans experience smell.
According to the research conducted at the Weizmenn Institute of Science, researchers could tell by measuring the nerve responses whether a subject found a smell pleasant or unpleasant.
In the experiment headed by Prof. Noam Sobel, the researchers inserted electrodes into the nasal passages of volunteers and measured the nerves' responses to different smells in various sites with each measurement capturing the response of thousands of smell receptors.
They found that the strength of the nerve signal varied from place to place on the membrane and it appeared that the receptors are not evenly distributed, but rather are grouped into distinct sites, each engaging most strongly with a particular type of scent.
Further investigation showed that the intensity of a reaction was linked to the odour's place on the pleasantness scale as the site where the nerves reacted strongly to a certain agreeable scent also showed strong reactions to other pleasing smells and vice versa.
"We uncovered a clear correlation between the pattern of nerve reaction to various smells and the pleasantness of those smells. As in sight and hearing, the receptors for our sense of smell are spatially organized in a way that reflects the nature of the sensory experience," Prof. Sobel said.
The implication of the study is that a pleasantness scale is, indeed, an organizing principle for our smell organ.
The study has been published in Nature Neuroscience.

The parish church of the Nativity of St John the Baptist dominates the lake: built in the 17th century (around 1635), it has undergone numerous works
It consists of a square bell tower-porch (17th century) covered by an imperial roof opening onto a three-aisle vessel with two cross-vaulted bays and a choir with a flat chevet covered by a ribbed vault. The choir and the aisles are lit by 6 bays with figurative stained glass windows made by the master glass artist Alfred Georgeon (20th century). The building is reinforced on the outside by buttresses
This small church has interesting liturgical furniture made in the 18th century by carpenters who were most certainly local and integrated the particularities of the Doubs. The main altarpiece, made of painted and gilded carved wood, is a good example of the Haut-Doubs baroque style, combining the architectural vocabulary of antiquity with cherubs and scenes from the Bible.
We can also mention the pulpit (carved wood), a painting of the Virgin and Child (17th century) and the evangelists painted on the choir vaults (15th century).

Your plastic chopping board could be harbouring potentially deadly bacteria including salmonella and E.coli.
With their wipe clean services, many cooks mistakenly believe plastic chopping boards are the way forward to stop bacteria from raw meat contaminating their food.
However several shocking studies have revealed bacteria actually multiplies much quicker on plastic boards, which could leave you more likely to give yourself a bout of food poisoning - or worse.
A study by the University of Wisconsin found that bacteria including potentially deadly salmonella left overnight on a plastic chopping board "thrived and multiplied."
Perhaps surprisingly, the bacteria on a wooden chopping board did not survive overnight.
Many believe this is because plastic boards, which wear out quickly, are more likely to have dents and grooves caused by cutting.
These dents and grooves make them much harder to clean and provide the perfect environment for bacteria to thrive and multiply.
Researchers also raised concerns that mould can grow under the surface of plastic boards, leading to staining and potential health risks.
Salmonella infections, known as salmonellosis, can prove deadly to children, the elderly or those with a weakened immune systems.
However - the problem can be avoided if you have a dishwasher.
Dr Ben Chapman, an associate professor and food safety specialist at North Carolina State University says the high temperatures inside a dishwasher will kill bacteria on a plastic chopping board, while wooden boards are not suitable for dishwashers.
His advice is to use a plastic chopping board for raw meat, and wash it in a dishwasher. However, for ready prepared foods or vegetables, wooden boards are the preferred alternative.
Cooking website AllRecipes recommends the best way to prevent illness is to clean chopping boards with hot water and soap before and after each time they're used, as well as drying them with a towel as soon as they're washed.

invalidate-rectangle
Generic Function
Summary
Invalidates the rectangle associated with the object, which causes it to be redisplayed.
Package
graphics-ports
Signature
invalidate-rectangle object &optional x y width height => result
Arguments
object
An instance of a subclass of graphics-ports-mixin or a subclass of pinboard-object.
x
A real number.
y
A real number.
width
A real number.
height
A real number.
Values
result
A boolean.
Description
By default, the generic function invalidate-rectangle invalidates the whole rectangle, but this can be limited by passing the optional arguments.
The effect of invalidating an area is to cause the area to be redrawn. It has no effect on pixmap-port. When the pane has a supplied display-callback , this callback is called with an area containing the area specified by the argument to invalidate-rectangle. However, the call to display-callback is asynchronous, and the system coalesces areas from calls to invalidate-rectangle and actual expose events, so there is not a one-to-one relation between calls to invalidate-rectangle and invocations of display-callback .
In general, invalidate-rectangle should not be called inside the display-callback . If it is called, it must be conditional, otherwise this will cause repeated redisplay.
Notes
With drawing-mode :quality, drawings are done with anti-aliasing, which means that they affect pixels which are not obviously part of the drawing. For example, drawing a rectangle with x = 10 may affect the pixel at x = 9. This needs to be taken into account when computing the arguments to invalidate-rectangle.
For pinboard objects the recommended way of forcing redraw is redraw-pinboard-object, which takes anti-aliasing into account.

Some examples of the functionality of event PROCESS AFTER INPUT, also the statements MODULE, FIELD and CHAIN are covered.
 - checking entered field values (calling error messages, start calculations, search in the database whether the entered value does actually exist, ...)
 - catching menu actions, and starting related functions
 - processing data entered
The system variable SY-DATAR indicates whether something has been changed in the fields contents of the screen. This could be useful in the program, e.g. to determine if it's necessary to save the transaction data. Checking single fields can be done with the .. ON REQUEST option of FIELD .. MODULE ..
Example: An example of PAI implementation

 *-----------------------------------------------------------------------
 * MODULE: D1310_MENU_RESPONS
 *-----------------------------------------------------------------------
 * Responding to the end users menu-action
 *-----------------------------------------------------------------------
 MODULE D1310_MENU_RESPONS INPUT.
 OK-COPY = OK-CODE. "Good trick to prevent a ...

 CASE OK-COPY.
 WHEN SPACE. "Special actions on empty OK-CODE ?
 WHEN 'QUIT'. "Quit (connected to F12 in menu painter)
 LEAVE TO SCREEN 900. "Go to DYNPRO 900
 WHEN 'HNDL'. "Perform: HANDLE_IT
 PERFORM HANDLE_IT.
 ENDCASE.

 ENDMODULE.
Note: the OK-CODE should always be cleared to make sure the choosen action won't be repeated in the currently active screen, or initiate another function in a follow up-screen.

The MODULE statement
Modules are the ABAP routines that can be called in the DYNPRO flow logic. They are built like any other FORM-routine, except the use of USING and CHANGING (and TABLES) is not possible. Some guidelines:
 - A module starts with MODULE <name> OUTPUT or MODULE <name> INPUT. PBO modules are indicated with OUTPUT (before), PAI modules by INPUT(after).
 - The end of a module: ENDMODULE
 - All ABAP statements are valid for modules
 - (Thus) FORM routines can be called from modules.
Throwing an error MESSAGE from a MODULE
The flow logic can indicate that a certain field entry is not accepted. This is done from the ABAP that calls a MODULE. Method: The ABAP initiates an ERROR message with the MESSAGE statement, for example MESSAGE E999 WITH 'You did wrong, don''t do that again'. The DYNPRO's behaviour can be controlled with this statement.
The FIELD statement
An important part of the screen is a of course a field. When processing from ABAP it is possible to check a field's contents. If a MODULE is created to check the field, this MODULE can be linked to the field in the DYNPRO with the statement FIELDin the flow logic of a DYNPRO. Syntax:
FIELD TABNAME-FIELDNAME MODULE D1310_FIELDNAME.
If MODULE D1100_KUNNR initiates an E-message, the end-user can correct the contents so that the error is solved. But there's more to the FIELDstatement, check out the on-line help system for the other options.
An example of a field check, try it out and watch what happens with the screen when the value '123' is entered for TABNAME-FIELDNAME.
*-------------------------------------
* MODULE: D1310_FIELDNAME INPUT.
*-------------------------------------
* Check: the value of FIELDNAME from
* table TABNAME may not equal '123'.
*-------------------------------------
MODULE D1310_FIELDNAME INPUT.
 IF TABNAME-FIELDNAME EQ '123'.
 MESSAGE E999.
 ENDIF.
ENDMODULE.
The CHAIN statement
With the statements CHAIN and ENDCHAIN in the flow logic of a DYNPRO, fields can be grouped together. In practice is possible that not just one field but a combination of fields lead to an error. E.g. if a header and position are the input fields, the values entered could be a legal header and a legal position. But the combination could be wrong. If a MODULE within a CHAIN .. ENDCHAIN kicks off an E-message, the end-user can adjust all the fields within the CHAINto solve the problem.

(**) Gray codes.
An n-bit Gray code is a sequence of n-bit strings constructed according to certain rules. Find out the construction rules and write a predicate with the following specification:
% gray(N,C) :- C is the N-bit Gray code
gray :: Int -> [String] gray 0 = [""] gray n = let xs = gray (n-1) in map ('0':) xs ++ map ('1':) (reverse xs)
A similar solution using list comprehension to build the sub-lists:
gray :: Int -> [String] gray 0 = [""] gray n = [ '0' : x | x <- prev ] ++ [ '1' : x | x <- reverse prev ] where prev = gray (n-1)
The Gray code can be recursively defined in the way that for determining the gray code of n we take the Gray code of n-1, prepend a 0 to each word, take the Gray code for n-1 again, reverse it and prepend a 1 to each word. At last we have to append these two lists. For more see the Wikipedia article.
Another completely different solution (using folds) that is way more efficient, because it needs just the space which is occupied by the list itself:
gray :: Integral a => a -> [String] gray 0 = [""] gray n = foldr (\s acc -> ("0" ++ s):("1" ++ s):acc) $ gray (n-1)
The key is that the algorithm just crawls one time over the input-list and uses the (++) operator in a way that it just has a running time of O(1).

Delaware School Health Profiles
Roberta Gealt, Principal Investigator
Secondary School Survey--Center for Disease Control and Prevention, Division of Adolescent and School Health through the Delaware Department of Education;
Elementary School Survey— Center for Disease Control and Prevention, Division of Adolescent and School Health through the Delaware Department of Educationand Nemours Health Prevention Services.
The School Health Profiles (Profiles) is a system of surveys assessing school health policies and practices in states, large urban school districts, territories, and tribal governments. Profiles are completed biennially by middle and high school principals and lead health education teachers. The secondary school survey has been administered every other year in even-numbered years. The Center develops the Delaware version of the survey, based on a CDC survey, with input from state and community agencies. CDAS has conducted fieldwork for the surveys, scanned the surveys to provide a data set, and provided some analyses and report writing, and dissemination of findings. The study reports data which relates to other Center studies on substance abuse, and provides statewide data on health instruction, policies and practice in schools, as well as professional development for health instructors in specific areas relating to CDC priorities also addressed in the student survey, the Youth Risk Behavior Survey. The secondary school survey has been conducted since 2004and the elementary survey, which is administered to principals only, was administered for the first time in 2010. These surveys are now conducted electronically. The basic CDC elementary school survey has been enhanced with additional questions consistent with the goals of Nemours.

To do: Glue cotton balls around a paper bear cut out to mimic snow piling atop a cave.
Time: 15 minutes
Materials: Cotton balls, glue, black paper, bear cut-out
Working with glue is a whole lot of fun for young children. Try this activity to speak about hibernation and build fine motor control at the same time!
– A black or dark blue piece of construction paper.
– A handful of cotton balls, 10-20
– White glue
– A white cut-out of a bear, or a white crayon
First, paste or draw your white bear onto the dark paper, bottom center. If you'd like, draw a light circle around the bear to represent a cave.
Next, place some glue in a small dish. Let your child dip the cotton ball in glue, and press each one carefully around the bear to create a snow covering!
While your child glues, speak about how the snow covering actually helps to keep the bear warm! It creates a layer of insulation from the cold weather outside, just like we stay warm in our homes all winter.

How to use watchdog
Overview
When enabled, the watchdog is a peripheral monitor that will reboot the system if it is not refreshed during a certain time interval. In ESF, the WatchdogService can be used by critical applications. If the specified application is alive, the service notifies the watchdog; if the application is down, the service stops notifying the watchdog and a hardware reset occurs.
The WatchdogService notifies the kernel watchdog driver using the /dev/watchdog device file. You can verify that the watchdog driver is installed using the following command:
ls –l /dev/watchdog
Configuration
To configure the WatchdogService, select the WatchdogService option located in the Services area as shown in the screen capture below.
The WatchdogService provides the following configuration parameters:
 - enabled - sets whether or not this service is enabled or disabled. If enabled, you must set a pingInterval periodicity compatible with the watchdog driver.
 - pingInterval - specifies the time between two watchdog notifications. This time is hardware dependent. Generally, the maximum time between two notifications should be between 30 seconds and 1 minute. 10000 milliseconds for the pingInterval is typically a good choice.
Code Example
The WatchdogService references a list of Critical Components that correspond to the applications implementing the CriticalComponent interface.
CriticalComponent is an interface that can be used to denote a component that is crucial to system operations. If a component implements CriticalComponent, then it must state its name as well as its criticalComponentTimeout. The name is a unique identifier in the system. The timeout is the length of time in milliseconds that the CriticalComponent must "check in" with the WatchdogService. If the CriticalComponent extends beyond the period of time specified in this timeout, a system reboot will be performed based on the WatchdogService configuration.
If at least one of the registered CriticalComponents has not "checked in" during the pingInterval time, the WatchdogService stops notifying the watchdog driver. The system reboots when the time interval reaches the hardware time that is programmed for the watchdog. When the WatchdogService is enabled and no application is using it, the service runs silently in the background.
An example of the WatchdogService can be found here.
The following code snippets demonstrate how to implement the CriticalComponent interface:
public class ModbusManager implements ConfigurableComponent, CriticalComponent, CloudClientListener
Registration of the class in WatchdogService::
if(m_watchdogService!=null){
 m_watchdogService.registerCriticalComponent(this);
}
Periodic call to checkin method of WatchdogService in the main loop (keeps watchdog notification alive):
if(m_watchdogService!=null){
 m_watchdogService.checkin(this);
}

When designing integrated microfluidic systems of the type shown in Figure 18.1, some important objectives are to:
1. Increase the throughput.
2. Improve the homogeneity of the mixture.
3. Obtain higher separation efficiency.
4. Perform detection faster.
However, it may not be possible to attain all these objectives, and there
can be a trade-off leading to an optimized design. In this section, using the techniques discussed in Chapter 17, "easy-to-use" circuit and device models are presented, which can be used to explore the design space and select an optimal design for integrated microfluidic systems to perform various functions. The model development is illustrated using the example shown in Figure 18.1. The models are, however, general enough that they can be applied or extended to other microfluidic systems. The development of a compact/circuit model for fluid flow due to a combined pressure and electrical potential gradient is first discussed. The compact model is described in two parts, namely, the electrical model and the fluidic model.
18.1.1 Electrical Model
For microfluidic devices that rely on the electrokinetic force as the driving force, the electric field must be computed first. In the case of electroosmotic flow (see Chapter 7 for details; here we restate only the essential equations to derive the circuit models), the potential field due to an applied potential can be computed by solving the Laplace equation:
У2ф = 0, (18.1)
where ф is the electrical potential. Since equation (18.1) predicts a linear potential drop for simple straight channels, the potential variation can be represented by linear electrical resistances. In order to develop a complete circuit that takes into account the charge stored in the electrical double

Baron Carlo Marochetti (_PHONE_)
Bronze on a granite pedestal
George Square, Glasgow
James Oswald (_PHONE_) was a prominent Reformist, noted orator, and twice MP for Glasgow. Marochetti executed two other monuments in George Square, equestrian statues of the Queen and Prince Albert, and also the well-known one of the Duke of Wellington outside the former Royal Exchange (now the Glasgow Gallery of Modern Art). Compared to those, this statue seems unexceptional, but Oswald's frock coat and casual pose seemed quite startling in its day: "[t]he representation of a public figure in contemporary dress was unusual for this time and provoked some hostile criticism," writes Ray McKenzie (131). Stones used to be thrown into his hat, and perhaps still are. One of the passers-by who managed to get a stone into it was, apparently, Joseph Conrad (see McKenzie 132). Marochetti's Wellington has fared much worse, being rarely seen without a traffic cone on his head, and sometimes on his horse's head too.

Image Number 3 for United States Patent _TAG_.
The present invention discloses a spectral measurement method via continuous light source and discrete light source, and a measurement instrument for non-invasive detection of human body tissue components. Said instrument includes an incident unit, a probe, a receiving unit and a data processing unit. Said composite spectral measurement method improves or strengthens the output light intensity at the wavelength that carries information of the target component within human body. It enables the spectral detection in the whole wavelength range, and thus significantly enhances the SNR of the detecting system. In the non-invasive detection instrument, light from both the continuous light source and discrete light source can be firstly selectively light-split by AOTF, or AOTF conducts light-splitting for the continuous light source, while the discrete light source LD is controlled by a spatial chopper. When data of the spectral curves achieved from said continuous light source and discrete light source are processed, data acquired under different measuring modes can be compared.
