Municipal Waste Diversion in Ontario
By Linda Varangu
Over the past years we have seen a public awakening to the concerns of managing solid waste. With total waste
quantities generated across the province of Ontario at around 10 000 000 tonnes per year, the diversion of some of
this waste would be welcome. The public has been well served by local municipal waste diversion programs such
as recycling programs, household hazardous waste programs, backyard composting programs, reuse centres, and
education on less wasteful and toxic alternatives. Through these various programs, Ontario residents were able to
divert an estimated 900 000 tonnes from landfills in 1994, with approximately 500 000 tonnes coming from the blue
box program.
The blue box program has become an institution in households across Ontario. Many blue box programs now
include materials such as textiles, different types of plastics, and household fine paper in addition to metal cans,
glass bottles, newspaper, and plastic bottles. 3.2 million households in Ontario (or 85%), now have access to
recycling programs. In various municipalities, pilot programs have demonstrated that householders can achieve
solid waste diversion of over 75% using a combination of reduction, reuse, composting, and recycling. Considering
that only a few years ago, even 50% diversion was considered unattainable, these diversion rates are remarkable.
Several years ago, federal and provincial governments set diversion goals of 50% by the year 2000. How likely is it
that Ontario municipalities will achieve this? Not very. Lately, the diversion rate for municipalities has reached a
plateau at 25-35%. Significant changes in waste diversion programs must be offered that include attention to the
organic stream if we are to go beyond this plateau. Instead of expanding waste diversion programs, however,
funding cuts may see the erosion of support for some programs currently offered by municipalities.
Many municipalities are now concentrating on activities that will enable them to run their programs as efficiently and
cost effectively as possible. One of the key objectives is to keep recycling operations costs as low or lower than
garbage collection costs. The strategy includes reducing operational costs and services, and increasing revenues
from materials sold through recycling programs.

COMPOSTING is an effective recycling strategy for turning otherwise unrecyclable organic wastes into a valuable
resource. It is estimated that approximately 40 to 70 percent of the total municipal solid waste stream could be
composted. Some examples of organic material that can be composted include fruit and vegetable scraps, tea bags
and coffee grounds, leaves and yard wastes, agricultural crop residues, paper products, sewage sludge, and wood.
Composting is a natural biological decomposition process by which microorganisms (primarily bacteria) break down
organic material. There are two types of composting processes (performed by different types of bacteria): aerobic
and anaerobic. Aerobic composting requires oxygen, while anaerobic composting takes place in an oxygendepleted environment. The by-products of anaerobic composting include volatile amines (which smell like rotten
fish), hydrogen sulphide (which smells like rotten eggs), and methane. The anaerobic process is not recommended
for backyard composting.
In addition to oxygen, aerobic microbial activity requires food (carbon for energy and nitrogen for protein building),
and adequate moisture and temperature. During the aerobic composting process, bacteria break down the organic
waste, and the pile gives off heat. The compost temperature should not be allowed to exceed 70°C, because most
microorganisms involved in composting die or become inactive above this temperature. When the compost no
longer generates heat, it is generally ready to be used.
Composting is, of course, not a new idea, but centralized composting facilities have only recently appeared in
government, institutions, and various rural settings. There are presently 162 composting facilities in Canada, of
which 112 are municipal and 50 are private. These facilities processed almost 700 000 tonnes of organic waste in
1994. There are three basic types of centralized aerobic composting methods:
 - the windrow method consisting of long triangular rows known as windrows, which are turned mechanically;
 - the aerated static pile method, which involves forming windrows over perforated pipes, and supplying air to
 the micro-organisms through the pipes rather than turning the compost; and
 - the in-vessel method, where the organic material is composted inside a drum, silo, agitated bed, covered or
 open channels, batch container, or other structure. The process conditions are closely monitored and
 controlled. The material is aerated and mechanically turned or agitated.
Standardized testing methods are needed that would certify the maturity and stability of different compost batches.
The quality of compost is largely defined by its intended use. High quality compost is used in agriculture,
horticulture, landscaping, and home gardening. Medium and low quality compost is used in erosion control,
roadside landscaping, as a landfill cover, and in land reclamation projects.

How can animation blueprints be shared among different skeletons?
Using retargeted animations will copy animation resources and animation blueprints, which is not reliable because when I modify the source animation blueprint, the copied version will not be modified synchronously. It would be nice if the copied animation blueprint could use different skeletons and inherit the source animation blueprint, but I don't know how to do it.
Now I've learned how to do these things. The reply has some questions about what I mean. I mean, animbp parent class uses skeleton A, subclass uses skeleton B, A and B may be completely different skeletons, for example, A is a human, B is a spider. They use the same logic, but the animation resources played vary with the skeleton. In subclass, I just need to replace each animation resource. Editing animation logic in the parent class will be synchronized to the subclass. Now I've done it.
Parent AnimBPClass：
AnimBP Subclass：
However, when UE4 started to design, epic did not seem to expect us to do so, so the support for this design was not good.I gave feedback and hope that the official modification function can support us to do as shown in the figure below, so that I can modify the bone name of blend in subclass.
Do you mean the different skeletons have differently-named bones, or are they different instances of the same skeleton (e.g. the default unreal mannequin, like when you have several marketplace packs in your project).
If it is the latter, I delete the skeleton from one pack, and then the engine asks me to assign the animations to a new skeleton, and I assign it the skeleton of the other pack's animations.
I think OP is asking about how to use different skeletons without having to make new animBPs for each one.
I haven't gotten too into this myself but I think probably the thing you need to do is actually make sure you are using the same skeleton for every character you animate. But, let's say you have a male and female version of the character that share the same skeleton that need to use different animations, you would do all your logic in a parent animBP for, say, the male and then create a child animBP of this for your female and use animation blueprint overrides to change the animations you want to use the female set.
In short, as far as I know, you can only use one skeleton per animBP so make all your characters that need to share an animBP with the same skeleton.
The skeleton is assigned per UAnimInstance class. (which your blueprint is derived from) If you want to change the skeleton asset association, you need to create a new class. This means that you have to make a main animation blueprint and create a child blueprint from it. (right click animbp and Create child blueprint class) Then change the skeleton association in the child blueprint Class Settings. (close the blueprint and open it again after doing this)
You will run into a problem after doing this, which is that the animation overrides are bugged and it will not allow you to select animations from your new skeleton. The only way to get around this is to create sequence variables in your main blueprint for every playback node, then update your variable assignments in the child blueprint. The only downside here is that some nodes, like random sequence player, does not support variable inputs.
possibly the lack of fast track, and a few other issues as well.
Its probably easier to right click the animation bp and choose the re-target option.
It will create a copy of everything tied to the skeleton you choose.
You can also overwrite existing files with this process.
I agree, its not as nice as being able to change skeleton on the fly, but every animation needs to be tracked to the correct skeleton still.
I think there is/has been some work put in to remove this limitation, but the reality is unless you specifically tag things to a skeleton the engine doesn't know how to operate the tracks.
With identical skeletons, the proper way to create a copy has been explained (even above) there's a full topic within this section of the forum that details the step by step process.
Not sure if this supports all animation features, fast track, etc. But to make a duplicate in a pinch it has worked well enough for me in the past.
going forward I'd probably refrain from it and make hard copies :stuck_out_tongue:
Fast path have never been affected on our end when using pure variable inputs, which makes sense as it's just a copy of a value or ref/address. The child class is using the same anim graph as its parent class, so it seems far fetched for it to be affected at all.
I updated my post to explain more specifically. Now I have a general idea of how to implement it, but UE4 still limits our development.
I got a lot of done in child BPs when putting al sequences and blend spaces with pins into their player (expose to pin) and then change class defaults and skeleton in the child. But I do not get it done for Aim Offset. Even if I am able to expose the BlendSpace Pin of AimOffset to a variable and change it in the child, it seems AimOffset Node is hard-bound to skeleton. Someone has a solution for using AimOffset in child Anim BP with different skeletons?
Known solution is not working for me. UE4.26.2
EDIT: Sorry, seems to be simply a problem in the Aim Offset of my child Anim BP. Not sure what it was in detail, but Aim offset in child Anim bp was not ready, other value name, etc. When I changed child AimOffset that it has correct anims, and also same value as aimoffset of parent, all runs fine in child anim bp,

Tool Care and Sharpening Instructions
To Sharpen a Garden Hoe
- Position the tool with the blade pointed up.
- File the outside edge only of the blade to a sharp angle (as shown) using the coarse side of the file.
- Using the mild side of the sharpener file, lightly remove any nicks or burrs from the inside edge of the blade keeping the file fairly flat and parallel to the blade.
- Finish off the outside edge of the blade with the mild side of the sharpening file to an even, sharp edge.
- Clean soil from the handle after each use.
- Check the wedge occasionally during use and tap back into place if needed.
- Once or twice a year, re-oil the handle using a penetrating wood oil finish like Tung Oil or Danish Oil.
- Clean soil off the blade after each use.
- Keep the blade sharp using the Farmer's Own File.
- Before storing for winter, oil the blade to prevent rust.

Subject 3 * 1/3 = 0 ???
Author rogervellacott
I always thought this was true
(1/3)*3 = 1
But Interbase and Firebird (and probably all the other RDBMSs) say
this equals 0.
Try
SELECT (1/3)*3 FROM RDB$DATABASE
I know there was some discussion of this on this group some time ago,
and no doubt some convincing explanations were given, but I am a
simple soul, and the more I try to cope with it, the more obviously
wrong it is.
Did you know that
1/3.00 = 0.33
and
1.00/3 = 0.33
You might think this was a useful way of rounding. But no,
3.333333/1.00 = 3.33333300
so unless you have already determined how many decimal places there
are in every element of your formula, you cannot know how many
decimal places there will be in the answer.
In my view, this behaviour invites errors. Not only is it
unintuitive, it gives the wrong answers to simple calculations, and
unpredictable answers to complex calculations, and that is not a good
idea.
Any chance of changing it next version? If integer operations are
desired, how about a div? Please don't tell me that current
behaviour is good. It isn't.

Smartphones to help fight stress from noise
traffic on Melbourne freeway
Crowd sourcing data to identify urban noise hotspots could combat stress and improve productivity, say researchers (Source: Flagstaffotos)
Researchers from CSIRO and the University of New South Wales, built the program called Ear-Phone, using existing smartphone technology, to provide more detailed noise profile maps of cities, and help identify noise hotspots.
Noise pollution has been linked to stress in modern day life, with health effects including sleep disruption, hearing impairment, and psychological damage, impacting negatively on productivity
"This information is very important for town planning - if you want to build a school, and for real estate markets [and] buyers choosing the area they want to live in," says the study's lead author Dr Rajib Rana from CSIRO's Autonomous Systems Laboratory.
Rana says Australia does not actually measure ambient noise levels but in the United Kingdom noise maps are produced every five years.
However, he says, these don't measure noise levels directly but are based on models of traffic densities and the noise reflectivity off buildings. They also need to consider changes in levels throughout the day and night, and over small distances.
Rana says such existing methods of determining the noise distribution around a city is a very expensive process.
"Just think of the geographical extent of a city and covering every street," he says.
A better way
"We thought we could use samples from mobile phones as a crowd sourcing method of determining noise levels," says Rana, adding the modern smartphone already has sensors capable of collecting the data required.
"Just think of the built-in sensors [already] fitted to smartphones, such as accelerometers, gyroscopes, proximity sensors, light intensity monitors. Some even have temperature and humidity sensors," says Rana.
Smartphones also provide a location and time stamp to show exactly where and when the measurement was taken.
Rana and colleagues needed to develop an algorithm that records only useful measurements of ambient noise, and not other sounds like conversations, or keys jangling in bags, which could distort readings.
Initial tests were carried out on the streets of Brisbane, and readings were confirmed using commercially available sound meters.
Best results
The authors found the best results were obtained when people were outdoors, with the phone in their hand. Readings were far less accurate inside vehicles, or when the phones were in a bag or case.
"We only want to sample when the phone's in your hand, so the program determines if it's in a bag, pocket or case, by using its light monitor, accelerometer and proximity sensors, to determine its position and unwanted data can then be discarded," says Rana.
"GPS readings are used to determine movement below 6 kilometres per hour, which is the average the speed of the person walking, and a valid GPS signal means they're outdoors."
The research reported on the pre press website, indicates the program can detect the phone's position with an accuracy of 84 per cent.
The noise level and GPS co-ordinates are then sampled every minute and stored along with the location and time, before being uploaded to the database when a free Wi-Fi connection is detected.
According to Rana, the next challenge is to develop a sustainable incentive mechanism to get people motivated to participate.

Advocating for School Psychologists in Response to the APA's Proposed Model Act for State Licensure of Psychologists: 10 Things State Associations Can Do To Help
By Anastasia Kalamaros Skalski
NASP has created a roadmap for state associations to respond to the model act. This roadmap contains extensive information on the model act, checklists for assessing your state's risk for exposure to these proposals, and suggestions for working to combat them. The full roadmap is available at _URL_
Exhibt E in this roadmap details the top 10 essential advocacy activities for state associations. These activities include:
 1. Identify leaders and a clear set of procedures for monitoring and responding to the introduction of potentially harmful state legislation, regulations, or policies. Suggested leaders include: State Association President, NASP Delegate, State GPR/legislative chairperson, SPAN Coordinator, state lobbyist, etc.
 2. Conduct a needs assessment of the advocacy skills and knowledge of leaders and members. Prepare school psychologists as needed so that they clearly understand key advocacy messages and specific strategies that they can personally use in responding to this issue. Consult the NASP GPR Committee as needed in building this capacity.
 3. Conduct a 'risk' assessment of how vulnerable your state is to potential policies or legislation that would remove the right of nondoctoral school psychologists to use the 'psychologist' title and to engage in psychological practice in school settings.
 4. Complete the NASP Advocacy Roadmap for States: Profile of School Psychology Credentialing and Psychologist Licensing (Exhibit D).
 5. Respond to needs assessment, risk assessment, Profile of State Credentialing, and other NASP Advocacy Roadmap for States materials by developing a State Action Plan (Exhibit I). To be most useful, the state plan should have concrete recommendations of specific actions (e.g., advocacy training, developing a legislative alert system, setting up a phone tree for contacting legislators, etc.) to be taken to improve awareness, communication and message development, and advocacy skills.
 6. Set up an ongoing State Action Plan (Exhibit I) monitoring and evaluation system to ensure that all activities are completed on time and all pertinent information is communicated to state school psychology leaders and grassroots advocates.
 7. Establish communication methods with state school psychologists where regular updates are posted, questions answered, and time-sensitive action requests can be made. Suggestions include: website bulletin boards, blogs, brief e-mail announcements, and 'alert systems' that include e-mails, phone calls, or other types of announcements. Appoint specific leaders as responsible for managing all communications.
 8. Identify and reach out to key stakeholders and allies. Inform nonschool psychology colleagues and stakeholders about the model act issue and solicit their support in responding to any potential threatening legislation. Focus on the how disruptive potential legislation could be to services, policies, and procedures. Build coalitions that can be helpful in responding to this crisis while also building collaborative relationships and promoting shared missions regarding advocacy for essential student services.
 9. Prepare information packets or an 'issue kit' that can be accessed easily and quickly. Select key materials and information that succinctly explains the problem and how it can be resolved. Consult the NASP Advocacy Roadmap for States materials for ideas of key materials and resources.
 10. Work with state administrators, psychology licensing boards, state credentialing boards, and other public policy agencies and personnel to work out agreements that articulate why school psychologists are essential to the mission and purpose of schools. Be patient and never give up. Your colleagues and students are counting on you.
Several state associations have made a significant effort to inform their members about the impact that the model act could have on practices within their state and have also developed tools and strategies to help their members respond. Exhibit P in the Advocacy Roadmap provides examples of some of these products.

This paper presents Volumetric Velocimetry (VV) measurements for a jet in crossflow that is representative of film cooling. Volumetric velocimetry employs particle tracking to non-intrusively extract all three components of velocity in a three-dimensional volume. This is its first use in a film-cooling context. The primary research objective was to develop this novel measurement technique for turbomachinery applications, whilst collecting a high-quality data set that can improve the understanding of the flow structure of the cooling jet. A new facility was designed and manufactured for this study with emphasis on optical access and controlled boundary conditions. For a range of momentum flux ratios from 0.65 to 6.5 the measurements clearly show the penetration of the cooling jet into the freestream, the formation of kidney-shaped vortices and entrainment of main flow into the jet. The results are compared to published studies using different experimental techniques, with good agreement. Further quantitative analysis of the location of the kidney vortices demonstrates their lift off from the wall and increasing lateral separation with increasing momentum flux ratio. The lateral divergence correlates very well with the self-induced velocity created by the wall-vortex interaction. Circulation measurements quantify the initial roll up and decay of the kidney vortices and show that the point of maximum circulation moves downstream with increasing momentum flux ratio. The potential for non-intrusive volumetric velocimetry measurements in turbomachinery flow has been clearly demonstrated.

Two of the most enigmatic pieces of Irish sculpture can be found in a small cemetery on Boa Island in Co Fermanagh. The larger sculpture is a two-sided 'Janus' figure, with depictions of a bearded figure on both sides. Both of the depictions show an oval-faced man with large almond-shaped bulging eyes, and a straight nose. In Celtic culture, heads were very important because they were thought to contain a person's spirit after their death. Severed heads were taken in triumph after battles.
One side has the tongue partially sticking out, the other seems just to be an open mouth. The head just merges into the body without a clear neck, and the arms are crossed over what appears to be a belt. The base of the larger sculpture was found at a later time, and is now propped up against the figure. At the top of the heads there is a groove where people today leave coins as an offering. The smaller figure is called the 'Lustymore Man', and was found on the neighbouring Lustymore Island. It appears to be more weathered and more plainly carved. This figure is only one-sided, but has a lot of similarities with the larger figure. It seems to also depict a man with a straight nose and open mouth and its arms are crossed.
The reasons for creating these stone sculptures and the dates of their creation are not certain. They may have been part of pre-Christian religious sites, or they may have been made by early Christians who included older pagan beliefs in their grave sites. Boa Island's bilateral figure has been compared to another two-faced figure from Holzgerlingen, Germany and the Tandragee Idol, which is in a collection in St. Patrick's Cathedral, Armagh.

Have you ever wondered why Chicago is called the Windy City? It's a nickname that has intrigued people for decades. Is it because of the city's weather patterns or something else entirely? In this article, we'll explore the origins of this famous nickname and delve into the factors that contribute to Chicago's windy reputation. So, grab a cup of coffee, and let's uncover the story behind the Windy City!
Table of Contents
Why is Chicago Called the Windy City? The Origins of the Nickname
Chicago's journey as the Windy City began in the aftermath of the devastating Great Chicago Fire of 1871. After the fire, the city needed to rebuild itself, and word spread about its resilience and determination. However, it was a newspaper article published in The New York Sun that truly put Chicago on the map.

Bold Claims and Metaphors
In an editorial published on October 25, 1871, Charles Dana, the editor of The New York Sun, expressed his astonishment at Chicago's rapid recovery. He commended the city's spirit but also made a few bold claims that would forever link Chicago to the nickname.
The Blustery Politics
Dana's editorial praised Chicagoans for their resilience but also drew attention to the city's reputation for blustery politics. He used the metaphor of the wind to describe the politicians who were known for their grandiose speeches and empty promises. And thus, the nickname "Windy City" was born.

Weather Patterns and Windy Chicago
The Geographical Factors
Chicago's location, situated on the southwestern shore of Lake Michigan, plays a significant role in the city's windy reputation. The city's proximity to the Great Lakes creates a unique microclimate that often experiences strong winds.
The Lake Effect
The Great Lakes, particularly Lake Michigan, act as giant natural fans for Chicago. The temperature differences between the lake and the land create a phenomenon known as the lake effect. This effect leads to the formation of gusty winds, especially during the cooler months.
The Architecture Amplifier
Chicago's iconic skyline, adorned with towering skyscrapers, contributes to the city's windiness. The sheer height of these buildings creates a wind tunnel effect, intensifying the already blustery conditions.
The Engineering Marvel
The design of these skyscrapers takes into account the city's windy nature. Architects employ innovative techniques to ensure structural stability and mitigate the impact of strong winds on these towering structures.
The Windy City Culture
Embracing the Nickname
Over the years, Chicagoans have fully embraced the Windy City moniker. They wear it as a badge of honor, symbolizing their resilience, determination, and their ability to weather any storm that comes their way.
The Windy City Spirit
Chicago is a city that never sleeps, with an energy that matches its winds. From its bustling downtown to its vibrant neighborhoods, the Windy City is constantly buzzing with activity. It's a place where dreams are pursued, and opportunities are embraced.

Migrant Education Program
over 2 years ago
The Migrant Education Program
The migrant education program provides help with education and other needs for children ages 3-21 who move frequently because they, their parents, or guardians work in agriculture, fishing, or forestry. Since 1996, the United States government has offered this assistance to families who work in agriculture. The Program is available in every U.S. state and Puerto Rico.
Migrant Education Program Goals
The goal of the Program is to help children and young people overcome problems that result from repeated moves, so the children can be successful in school, graduate from high school and go onto college or employment after graduation. The additional support for children from highly mobile, agricultural families gives them the same change for success as other students. In addition, the Program offers some services for young people under the ages of 22 who are not attending school.
Migrant Education Program Services
In school, the Program offers extra help for the students who need it most. The Migrant Education Program at your school might offer:
- In-class assistance
- Help with homework before or after school
- Summer school
- Preschool for children ages 3-5
- Parent meetings
In the community, the program helps with support services. Some examples are:
- 24 hour accident insurance for all eligible children
- Helping parents learn about the community and where they can get help finding employment, child care, food, clothes, and health services
- GED or English classes for youth who are working
Who Qualifies for Migrant Education Program Services?
Children and young people ages 3 to 21 years old:
- Who have not yet graduated from high school;
- Who moved with their families across school district boundaries within the last 3 years;
- Who moved so they or their parents could look for work in agriculture, fishing, forestry, ranching, dairy, canneries or meat packing plants;
- And whose families depend on agriculture work to survive.
After You Join the Migrant Education Program:
- All information provided by parents if confidential by law.
- Oregon keeps the information on a computer system. Only Migrant Program personnel may use the system.
- The Migrant Education Program in your school district will decide which services each child will receive.
- All eligible children and youth are covered by accident insurance 24 hours a day. The insurance pays part of the medical costs when a child is injured in an accident, including in school sports.
- The children and youth are eligible for Migrant Education Program services for three years from the date of the qualifying move.
- The Program is voluntary and free to all eligible children.


COVID Face Shield
Introduction: COVID Face Shield
In the COVID age, you need to be able to protect yourself. I decided to make a face shield because people need to be able to protect themselves from COVID-19. In some places face masks and other face protections are required. In this Instructable, I will show you the supplies and tools needed to make your own homemade face shield, and the steps on how to build it.
 - Clear 2 Liter Bottle
 - Packaging Foam
 - Glue
 - Rubber Band
 - Box Cutter
 - Scissors
 - Hair Dryer
 - 2 Weights
Step 1: Gather the Supplies
Gather Supplies into your workspace, and keep everything spread out far enough so you have room to work.
Step 2: Prepare the Bottle
Take off the wrapper and mark lines on where to cut the bottle with the box cutter. Mark around where the neck of the bottle and the rest of the bottle flattens out, then mark at the bottom. Then one line going down the side. Next make two sets of lines on each side for a rubber band so it can go around your head. This will allow you to feed the rubber band in through one slit and back out of the second slit so you can tie the rubber band into a knot.
Step 3: Cut the Bottle
Cut the 2 liter bottle where you drew your lines. I recommend to cut at first using the box cutter until you have room to use the scissors to finish the cutting.
Step 4: Flatten the Plastic
In this step you will need to use a hair dryer to help flatten the plastic from the bottle that you cut out. You will need to have two heavy objects just to weigh down each side of the plastic so you can use the hair dryer. Then turn the hair dryer on high and put it close to the plastic so it will soften and form to the new position of being flat instead of curved.
Step 5: Headband for Shield
You will need some rubber bands for this step, you can use one big one or more than one by tying them together. When you have the desirable length of the band, then you would tie it through the holes that you cut out in the last step.
Step 6: Enjoy
You are now complete and now have a face shield to defend yourself from COVID.

Accenture Ireland has launched its new data science course specifically geared towards women working in STEM who want to explore this emerging field.
Many areas of STEM, data science included, suffer from talent shortages. It is a problem that many organisations hope to address with multi-pronged plans, employing different methods to find people with the skills they need.
Accenture Ireland hopes to address all this while better promoting diversity in one fell swoop with its new data science evening course, which it launched on 17 January.
The course, entitled the Women in Data Science Accelerator, will be held in evening sessions over six weeks. The programme hopes to provide a unique insight into the day-to-day life of a data scientist.
30 women who already hold applied data skills or otherwise applicable broad numerical experience will get the opportunity to develop their data science capabilities, network with other women building skills in the data science space and learn from exports in the field.
The course will be hosted at The Dock. Accenture's Medb Corcoran, who is the Ireland lead at Accenture Labs, will oversee the Leadership Stories segment of the programme and act as a judge.
"This course underlines Accenture's ongoing commitment to celebrating and fostering diversity, not only throughout the organisation but right across Ireland's technology sector," Corcoran said on the programme's launch day. "It is through programmes like our Women in Data Science Accelerator that we can bring together women who have a passion for data and analytics, and provide them with industry-led lectures, hands-on workshops and career guidance to help build a career in data science."

Cannot get rid of a link in a text view
Serious problem:
My application "Panel 1.0" uses a text view to hold the content. If you start the application and drag and drop a link from Safari into it directly, the link appears.
If you then delete the link and type some text, that text remains linked to the url the link had before and appears as linktext.
There is no way to get rid of it except restarting the application.
Most interesting: If you first type a space in the text view before pasting a link, you may type a space after the link followed by text and this text will not be linked.
Confusing!
Does anyone know (maybe by a call method) how to reset a text view to it's default state?
Thanks in advance!

Air Cooled vs Liquid Cooled Generator: How They Differ
Air Cooled vs Liquid Cooled Generator
Written by Jamie Masterson
The primary difference between an air-cooled generator and a liquid-cooled generator is the use of coolant. Air-cooled generators use surrounding air to cool the engine while liquid-cooled units use water, oils, or other coolants.
Let's dig deeper and see what differentiates them.
Air Cooled vs Liquid Cooled Generator: How They Differ
1. Use
Air-cooled generator
The air-cooling system is used by small to medium powered generators and they are the most widely available generators. The basic principle comes down to the heat dissipation technique. Air-cooled generators use the flow of air to cool the engine down.
Air cooling is the perfect system for any backup generator. They are mainly used in household, non-industrial, or smaller works (up to 22 kW). Most home appliances use air-cooled generators.
Use
Liquid-cooled generator
Unlike air-cooled generators, liquid-based cooling systems use a wide range of cooling liquids (just like your car) and can disperse heat much more efficiently. These generators feature enclosed radiator systems and are usually seen in higher-kilowatt units (above 22 kW).
Liquid-cooled generators are a bit more expensive, mainly because of the better heat dissipation technology. You'll find them in industrial and commercial settings.
2. Complexity
Air-cooled generator
The air-cooling system is simpler in design. The basic idea is to let the colder air pass through the hot parts of the engine. Engines produce a lot of heat, and the cooling system protects the engine from overheating. Modern engines achieve this feat by increasing the surface area.
Air-cooled generators are designed in such a way that cold air will enter the machine from one side and the hotter air will exhaust the system from another.
Air-cooled generator
Liquid-cooled generator
This might be true that the air cooling system is efficient, but it has its limitations. Air isn't a good heat conductor. As a result, the heating will be more difficult to handle as the engine runs for a long time.
Coolants like water, oil, or chemicals are much more efficient at heat dissipating. However, they are also more complex. The coolants require a closed system, a radiator, a thermostat, and many other additional components just to keep your generator going uninterrupted.
3. Maintenance
Air-cooled generator
Air-cooled generators are compact and lightweight by design. That's why they're much easier to maintain as well. Without all the complexities of a liquid-cooled engine, the maintenance of an air-cooled engine is pretty straightforward.
The general maintenance process includes checking oil levels, understanding safety precautions, and keeping an eye on the battery level.
Maintenance
Liquid-cooled generator
The more complex a system gets, the more sophisticated its maintenance becomes. You'll need more frequent and intricate maintenance tasks when it comes to taking care of the liquid-cooled generators.
Some of those tasks include inspecting the antifreeze level, lines, and connections for potential leaks; and making sure the liquid is working properly. Luckily, these complex machines have dedicated maintenance kits that need to be used regularly.
4. Requirements
Air-cooled generator
As mentioned above, air-cooled generators are mostly used in small power levels. The more steady output you need from your generator, the longer it has to run and the more sophisticated it needs to be.
A smaller and lighter air-cooled generator can provide you with around 8 – 22 kilowatts of power. That's why they're a good choice as an occasional backup power source. Air-cooled generators are mostly used in household tasks.
Air-cooled generator Requirements
Liquid-cooled generator
Designed for a more heavy and steady workload, liquid-cooled generators are the perfect solution for industrial or heavy-duty power supply tasks.
The greatest advantage of liquid-cooled generators is their longevity. They can provide a steady stream of power over an extended period of time. They are used in hospitals, databases, apartments, stadiums, malls, and other big infrastructures.
5. Noise
Air-cooled generator
Air-cooled generators produce a loud noise while working, mainly due to the combustion process happening inside. The intake or exhaust fan (if you have any) can also create noise that can be identified as loud.
In most cases, air-cooled generators produce a loud noise that can be irritating to many people.
Noise of generator
Liquid-cooled generator
Liquid-cooled generators are loud as well, but they are quieter than their air-cooled counterparts. The sound they produce can be easily contained using attenuated enclosures. Technically, liquid-cooled generators are more noisy than loud.
Pros & Cons of Air-Cooled and Liquid-Cooled Generators
Air-cooled
Pros
 - Portable and lightweight
 - Emergency backup solution
 - Perfect for smaller tasks
 - Less complex design
 - More affordable
 - Easy to use and maintain
Cons
 - Not good for heavy-duty jobs
 - Can't provide power over an extended period of time
 - They're loud
 - More prone to overheating
Liquid-cooled
Pros
 - They're more effective and powerful
 - Produces less noise
 - Perfect for long-term power supply
 - More durable and heavy-duty machine
 - Good in industrial/commercial environments
 - Perfect as a primary power source
Cons
 - More expensive
 - Less portable
 - Required more maintenance
Which one's best for you?
That greatly depends on how much power you need, for how long, and how much you are willing to invest. If you are looking for a backup power source for your home and household appliances, you won't need a large amount of power over a long time.
An Air-cooled generator will be your perfect choice in that case.
Air-cooled vs liquid-cooled generator - Which one's best for you
However, if you want more power over a long period of time, air-cooled generators won't cut it. You'll need more powerful liquid-cooled generators. They'll be perfect for powering your industrial or commercial appliances.
The heavier the load, the more powerful the generator should be. Liquid-cooled generators offer a viable solution to mid-high level power demands.
FAQs
Q. Do generators have to be maintained?
Yes, of course. Like most other machines, your generator will also require regular maintenance. The frequency and intensity of the maintenance will depend on the quality of your generator. Lightweight and smaller units will need less frequent maintenance.
Q. Can an air-cooled generator be installed indoors?
No. We don't recommend any kind of generators to be used indoors. It can cost you more and toxic fumes may build up indoors, leaving your lives at risk.
Q. Is a liquid-cooled generator worth it?
Yes. Not only do liquid-cooled generators provide a larger amount of power, but they also provide additional comfort by reducing fire hazards, and noise levels while increasing fuel efficiency.

Elytron currently supports aggregate security realms which are an aggregate of an authentication-realm and one or more authorization-realms. The authentication-realm is used to load the credentials of an identity or perform evidence verification and the authorization-realms are used to load the identity's attributes used for authorization. The principal undergoes a series of transformations before being used to load the authentication identity from the aggregate-realm.

The aggregate-realm now supports the attribute principal-transformer. This attribute is optional and allows the user to configure an additional transformation for the principal to undergo after the authentication identity is loaded but before the authorization identity is loaded.

The principal-transformer attribute references a transformer defined in the mappers configuration. This transformer can then be used when configuring an aggregate realm.

This blog post will be making use of:

elytron-examples/aggregate-realm-principal-transformer at master · wildfly-security-incubator/elytron-examples · GitHub

This example shows how to configure an aggregate-realm with a principal-transformer and how to secure a webapp using the aggregated realm for authentication and authorization.

Configuring the server

A WildFly CLI script that contains all of the commands that are used in this example can be found in the aggregate-realm-principal-transformer project in the elytron-examples repository.

Our first step will be to create our authentication and authorization realms, both of which will be filesystem realms.

The following command will create the authentication realm:

/subsystem=elytron/filesystem-realm=authenticationRealm:add(path=authenticationFS,relative-to=jboss.server.config.dir,encoded=false)

We will then add the identity with the name "guest" and password "guestPwd1!" to the authentication realm:

/subsystem=elytron/filesystem-realm=authenticationRealm:add-identity(identity="guest")

/subsystem=elytron/filesystem-realm=authenticationRealm:set-password(identity="guest", clear={password="guestPwd1!"})

Next, we create our authorization realm and add an identity with the name "guest-attributes" and the attribute 'Roles=Users':

/subsystem=elytron/filesystem-realm=authorizationRealm:add(path=authorizationFS,relative-to=jboss.server.config.dir,encoded=false)

/subsystem=elytron/filesystem-realm=authorizationRealm:add-identity(identity="guest-attributes")

/subsystem=elytron/filesystem-realm=authorizationRealm:add-identity-attribute(identity="guest-attributes",name=Roles,value=[Users])

We now have our two realms to be aggregated: authenticationRealm to load the credentials for the identity and authorizationRealm to load the attributes used for authorization. However, the principal for the identities is different for the two realms! To remedy this, we can add a constant principal transformer which will always return the principal "guest-attributes":

/subsystem=elytron/constant-principal-transformer=constantTransformer:add(constant="guest-attributes")

We can then configure our aggregate realm using our two new filesystem realms and principal transformer:

/subsystem=elytron/aggregate-realm=aggregateRealm:add(authentication-realm=authenticationRealm,authorization-realm=authorizationRealm,principal-transformer=constantTransformer)

Now our aggregate realm will use the principal "guest" to load the credentials from the authentication realm and then transform the principal to "guest-attributes" to load the attributes from the authorization realm.

We then add a security domain which makes use of our aggregate realm:

/subsystem=elytron/security-domain=simpleDomain:add(realms=[{realm=aggregateRealm}],default-realm=aggregateRealm,permission-mapper=default-permission-mapper)

We also configure a http-authentication-factory to secure our web application with our new domain:

/subsystem=elytron/http-authentication-factory=http-auth:add(http-server-mechanism-factory=global,security-domain=simpleDomain,mechanism-configurations=[{mechanism-name=BASIC,mechanism-realm-configurations=[{realm-name=other}]}])

/subsystem=undertow/application-security-domain=other:add(http-authentication-factory=http-auth)

Finally, we reload the server:

reload

Note: There is now the option to aggregate the attributes of an identity from multiple authorization realms. The principal used for all the authorization realms will be the same one (i.e. the transformed principal if a principal transformer is defined).

Deploying and accessing the application

We're going to make use of the simple-webapp project. This application allows you to access a secured servlet if your identity has the attribute Roles=Users. It can be deployed using the following commands:

cd $PATH_TO_ELYTRON_EXAMPLES/simple-webapp
mvn clean install wildfly:deploy

You can access the application at http://localhost:8080/simple-webapp/.
Try logging in with the username: "guest" and password: "guestPwd1!"
You are successfully authorized to access the secured application, which means our transformer worked and the attribute Roles=Users was successfully loaded from the authorization-realm using the principal that was transformed from 'guest' to 'guest-attributes'.

Summary
This blog post has shown how to use the new optional attribute principal-transformer in an aggregate-realm to transform the principal between the authentication-realm and authorization-realm.

For more information on aggregate realms checkout:

wildfly/Aggregate_Security_Realm.adoc at master · wildfly/wildfly · GitHub
The Elytron Client allows remote clients to authenticate using Elytron. The configurations for these clients can be specified in two ways: using an XML configuration file or using a programmatic approach.

With WildFly 18, it is now possible to specify masked passwords as credential passwords and key store passwords for client authentication.

This blog post will demonstrate how to generate a masked password using the WildFly PasswordFactory and how to use this masked password as a credential in the authentication client using the two configuration methods.

Generating a Masked Password

A masked password consists of the following attributes:

 - 'algorithm' The algorithm used to encrypt the password. If this attribute is not specified, the default value is "masked-MD5-DES".
 - 'key-material' The initial key material used to encrypt the password. If this attribute is not specified, the default value is "somearbitrarycrazystringthatdoesnotmatter".
 - 'iteration-count' The iteration count used to encrypt the password. This attribute is required.
 - 'salt' The salt used to encrypt the password. This attribute is required.
 - 'masked-password' The base64 encrypted password (without the "MASK-" prefix).
 - 'initialization-vector' The initialization vector used to encrypt the password. This attribute is optional.

A list of the supported algorithms can be found at Passwords.

For our example, we will be generating a masked-MD5-DES type password. We can generate this password as follows:

static final Provider ELYTRON_PROVIDER = new WildFlyElytronProvider();
public static void main(String[] args) throws Exception {
 String algorithm = "masked-MD5-DES";
 char[] keyMaterial = "somearbitrarycrazystringthatdoesnotmatter".toCharArray();
 byte[] salt = "_PHONE_".getBytes();
 int iterationCount = 100;
 String clearPassword = "password1!";
 byte[] initializationVector = null;
 PasswordFactory passwordFactory = PasswordFactory.getInstance(algorithm, ELYTRON_PROVIDER);
 MaskedPasswordAlgorithmSpec maskedAlgorithmSpec = new MaskedPasswordAlgorithmSpec(key, iterationCount, salt);
 EncryptablePasswordSpec encryptableSpec = new EncryptablePasswordSpec(clearPassword.toCharArray(), maskedAlgorithmSpec);
 MaskedPassword original = (MaskedPassword) passwordFactory.generatePassword(encryptableSpec);
 MaskedPasswordSpec maskedPasswordSpec = new MaskedPasswordSpec(keyMaterial, iterationCount, salt, masked);

 //Get the masked password as a string
 String maskedPassword = ByteIterator.ofBytes(maskedPasswordSpec.getMaskedPasswordBytes()).base64Encode().drainToString();
 System.out.println(String.format("Masked Password: " + maskedPassword));
 //Verify the masked password

Lower Plants Collections
The origins of the botanical collections in Cardiff began in 1867 when Cardiff Naturalists Society formed and influenced the development of Cardiff Free Library, Museum and Schools of Science and Art. The first noteworthy botanical purchase of the society was in 1870 with the Conway Collection.
An estimated 337,000 specimens in Amgueddfa Cymru — National Museum Wales herbarium are lower plants, mainly consisting of bryophytes (mosses, liverworts and hornworts) coming to around 280,000 specimens. However, there are also many specimens of lichens (45,000), fungi (6,700) and algae (5,000).
Keeping the collections safe and in good condition is part of the job of curators who work closely with the conservation department in the Museum.
Explore the collections online. We are gradually adding to these, so further catalogues will become available.

trailing slashes before matching ("/about/" -> "/about")
 2. always: always adds trailing slashes before matching ("/about" -> "/about/")
 3. preserve -> paths without a slash won't match paths with a slash ("/about" -> "/about", "/about/" -> "/about/")
If you need to match trailing slashes exactly, use the preserve value. In the following example, /about/ will not match /about and you will be sent to the NotFoundPage
<Router trailingSlashes={'preserve'}>
<Route path="/" page={HomePage} name="home" />
<Route path="/about" page={AboutPage} name="about" />
<Route notfound page={NotFoundPage} />
</Router>
useParams
Sometimes it's convenient to receive route parameters as the props to the Page, but in the case where a deeply nested component needs access to the route parameters, it quickly becomes tedious to pass those props through every intervening component. The router solves this with the useParams hook:
SomeDeeplyNestedComponent.js
import { useParams } from '@redwoodjs/router'
const SomeDeeplyNestedComponent = () => {
const { id } = useParams()
...
}
In the above example, we've pulled in the id route parameter without needing to have it passed in to us from anywhere.
useLocation
If you'd like to get access to the current URL, useLocation returns a read-only location object representing it. The location object has three properties, pathname, search, and hash, that update when the URL changes. This makes it easy to fire off navigation side effects or use the URL as if it were state:
import { useLocation } from '@redwoodjs/router'
const App = () => {
const { pathname, search, hash } = useLocation()
// log the URL when the pathname changes
React.useEffect(() => {
myLogger(pathname)
}, [pathname])
// initiate a query state with the search val
const [query, setQuery] = React.useState(search)
// conditionally render based on hash
if (hash === '#ping') {
return <Pong />
}
return <>...</>
}
If you'd like to programmatically navigate to a different page, you can simply use the navigate function:
SomePage.js
import { navigate, routes } from '@redwoodjs/router'
const SomePage = () => {
const onSomeAction = () => {
navigate(routes.home())
}
...
}
The browser keeps track of the browsing history in a stack. By default when you navigate to a new page a new item is pushed to the history stack. But sometimes you want to replace the top item on the stack instead of appending to the stack. This is how you do that in Redwood: navigate(routes.home(), { replace: true }). As you can see you need to pass an options object as the second parameter to navigate with the option replace set to true.
back
Going back is as easy as using the back() function that's exported from the router.
SomePage.js
import { back } from '@redwoodjs/router'
const SomePage = () => {
const onSomeAction = () => {
back()
}
...
}
Redirect
If you want to declaratively redirect to a different page, use the <Redirect> component.
In the example below, SomePage will redirect to the home page.
SomePage.js
import { Redirect, routes } from '@redwoodjs/router'
const SomePage = () => <Redirect to={routes.home()} />
In addition to the to prop, <Redirect /> also takes an options prop. This is the same as navigate()'s second argument: navigate(_, { replace: true }). We can use it to replace the top item of the browser history stack (instead of pushing a new one). This is how you use it to have this effect: <Redirect to={routes.home()} options={{ replace: true }}/>.
Code-splitting
By default, the router will code-split on every Page, creating a separate lazy-loaded webpack bundle for each. When navigating from page to page, the router will wait until the new Page module is loaded before re-rendering, thus preventing the "white-flash" effect.
Not code splitting
If you'd like to override the default lazy-loading behavior and include certain Pages in the main webpack bundle, you can simply add the import statement to the Routes.js file:
Routes.js
import HomePage from 'src/pages/HomePage'
Redwood will detect your explicit import and refrain from splitting that page into a separate bundle. Be careful with this feature, as you can easily bloat the size of your main bundle to the point where your initial page load time becomes unacceptable.
Page loaders & PageLoadingContext
Loader while page chunks load
Because lazily-loaded pages can take a non-negligible amount of time to load (depending on bundle size and network connection), you may want to show a loading indicator to signal to the user that something is happening after they click a link.
In order to show a loader as your page chunks are loading, you simply add the whileLoadingPage prop to your route, Set or Private component.
Routes.js
import SkeletonLoader from 'src/components/SkeletonLoader'
<Router>
<Set whileLoadingPage={SkeletonLoader}>
<Route path="/contact" page={ContactPage} name="contact" />
<Route path="/about" page={AboutPage} name="about" />
</Set>
</Router>
After adding this to your app you will probably not see it when navigating between pages. This is because having a loading indicator is nice, but can get annoying when it shows up every single time you navigate to a new page. In fact, this behavior makes it feel like your pages take even longer to load than they actually do! The router takes this into account and, by default, will only show the loader when it takes more than 1000 milliseconds for the page to load. You can change this to whatever you like with the pageLoadingDelay prop on Router:
Routes.js
<Router pageLoadingDelay={500}>...</Router>
Now the loader will show up after 500ms of load time. To see your loading indicator, you can set this value to 0 or, even better, change the network speed in developer tools to "Slow 3G" or another agonizingly slow connection speed.
Using PageLoadingContext
An alternative way to implement whileLoadingPage is to use usePageLoadingContext:
VIDEO: If you'd prefer to watch a video, there's one accompanying this section: _URL_
SomeLayout.js
import { usePageLoadingContext } from '@redwoodjs/router'
const SomeLayout = (props) => {
const { loading } = usePageLoadingContext()
return (

{loading &&
Loading...
}
{props.children}

)
}
When the lazy-loaded page is loading, PageLoadingContext.Consumer will pass { loading: true } to the render function, or false otherwise. You can use this context wherever you like in your application!
Loader while auth details are being retrieved
Let's say you have a dashboard area on your Redwood app, which can only be accessed after logging in. When Redwood Router renders your private page, it will first fetch the user's details, and only render the page if it determines the user is indeed logged in.
In order to display a loader while auth details are being retrieved you can add the whileLoadingAuth prop to your private <Route>, <Set private> or the <Private> component:
//Routes.js
<Router>
<Private
wrap={DashboardLayout}
unauthenticated="login"
whileLoadingAuth={SkeletonLoader} //<-- auth loader
whileLoadingPage={SkeletonLoader} // <-- page chunk loader
prerender
>
<Route path="/dashboard" page={DashboardHomePage} name="dashboard" />
{/* other routes */}
</Private>
</Router>
FatalErrorPage
Every Redwood project ships with a default FatalErrorPage located in web/src/pages/FatalErrorPage. This page gets rendered when an error makes its way all the way to the top of your app

The MFAH, The Rienzi Collection, bequest of Caroline A. Ross
An inscription on a slip of paper found behind J. T. Mitchell's sweet portrait of two young children identifies the sitters as the twins Elizabeth Mary and Augustus William Hillary.
As was typical for the time, the twins are depicted wearing almost identical clothing--long muslin dresses with blue ribbon sashes. In the eighteenth and nineteenth centuries, both boys and girls wore skirts until male children were "breeched," or given trousers to wear, at some point between the ages of 4 and 6. The artist has taken care to distinguish their genders: Elizabeth, her head covered by a lace bonnet, cradles a fluffy lapdog in her arms while Augustus gathers his sister in a protective embrace. The miniature's excellent state preserves the original coloration of the children's rosy cheeks and dramatic blue background.


Lease or a licence? The Court will decide
What's the difference and why does it matter?
Whether you are the landlord or the tenant, it is important to know whether your arrangement is a lease or a licence as the rights and responsibilities for both vary depending on which it is. If there is a dispute as to whether it is a lease or a licence, the Court will decide based on the realities of the situation.
In a recent case, there was an agreement described as a licence, but in fact, it was a lease.
What's the difference?
Licence: Does not give the tenant a legal interest in the property itself. It's just a contract giving the tenant permission to use the property.
Lease: Does give the tenant a legal interest in the property, giving the tenant exclusive possession. If you are the tenant, this means you can exclude anyone else from the premises, even the
The Court will consider the parties intentions to decide whether it is a licence or lease. It asks what a reasonable person would think once presented with the objective facts?
The Court also considers the power dynamic of the parties, and will try to help the tenants where possible.
In the case above, the court decided that the business was availing of a lease.
The case highlights the importance of getting legal advice if there is any doubt about whether an agreement is a lease or a licence.

Error: An unknown error has occurred loading this published map
After creating and publishing a Published Map File (PMF) package, users are unable to open the PMF file in ArcReader. The following error is returned:
"An unknown error has occurred loading this published map."
In other situations, when users attempt to access a published map on ArcReader, the following error message is returned, and nothing is loaded:
"An unknown error has occurred while loading document."
There are several causes of this issue:
- Compatibility issue. This issue occurs due to users using different version of ArcReader and Publisher in ArcMap. For example, ArcGIS 10.1 PMF files are not backwards compatible with ArcGIS 10.0. In addition, ArcReader 10.1 cannot be installed on the same machine as ArcGIS Desktop 10.0, so this explains the error message.
- The location of the PMF files is altered. The end user does not have access to both the PMF and the data. In theory, if users do not have at least read access to the data, users are unable to open the map. Granted, that also depends upon how the map is published.
- PMF files are corrupted.
Solution or Workaround
Follow the suggested solutions below to solve this issue:
Download the right version of ArcReader which is compatible with version of Publisher in ArcMap. The link for downloading different ArcReader releases can be found here.
Ensure the user of the second machine has permission on the PMF and folder.
Create a new map document and publish it using the Publisher extension. To do this, follow the steps below:
1. From the Publisher toolbar, select Publish Map. 2. Create a new folder. The new folder is used to house both the PMF file and the data package. The reason for this is to keep all the elements of the published map together for future distribution to users who have ArcReader. 3. Name the file, and click Save. 4. From the Publisher toolbar, select Create Data Package. 5. Select the PMF file generated in Steps 1 - 3. Click Open. 6. Specify the save location. Use the folder created in Step 2. 7. Ensure that the Data Format is set to File Geodatabase. 8. Ensure that the box under Options is unchecked. 9. Click the Extent tab. 10. Check the boxes next to include all features in the dataset. Click OK. 11. Once the Data Package is created, send the entire folder created in Step 2 to the end user, and they now can access to the PMF as well as all of the published data.

text: We investigated the effects of single electron charging energy in high temperature superconductors. Various phenomena originating from Coulomb blockade were observable in superconducting tunnel junctions. High quality tunneling junctions were fabricated from c-axis oriented NdBa2Cu3O7–delta/PrBa2Cu3O7–delta/NdBa2Cu3O7–delta thin film multilayers by the pulsed laser deposition method. The current-voltage characteristics (CVCs) show a Coulomb gap for Cooper pair tunneling when the charging energy exceeds the Josephson coupling energy. We found a regime in which the CVCs exhibit sharply defined Coulomb steps due to single electron dynamics and nonlinear tunneling rates. From the obtained Coulomb staircase, the tunneling resistance shows a quantum effect: It is modulated by the tunneling current in the form h/4e2RT~[sin(piI/I0)2/(piI/I0)]. We suggest an interpretation involving the quantum resistance h/e2 and the competition between the charging, Josephson, and thermal energies of the system. Our results give a perspective on a solid-state quantum system with considerable interest for direct application in quantum computing.

"I've got my ion you."
―Ion gunner
The ion cannon was a multi-scale weapon which could be fitted, in varying sizes and power levels, to just about any kind of starship, from small starfighters to the largest capital-class warships and space stations. Small-scale ion cannons were also used by various military organizations and/or criminals.
The principles behind ion cannon technology were too complex to explain to the average citizen of the galaxy, particularly . Suffice to say, such weapons allowed non Force-sensitive beings to harness the power of Force lightning. While ion cannons did little to no damage to organic beings, they were extremely effective in shutting down the electrical systems of any type of machine or mechanism that the beam came into contact with.
This article is called Ion cannon. Ion cannon has been written from a simple, Ric Olié point of view. A non-simple version of Ion cannon can be read on Darthipedia. Darthipedia is the Star Wars Humor Wiki.
Primitive ion cannons were used by Jawas as aids to the illegal procurement of technology, typically things such as droids or small vehicles, which they would then repair or rebuild and, as often as not, sell it back to whomever they had stolen it from. Pirates also prized ion cannons for the booty they yielded during raids.

COLOR BURST
A reference color subcarrier signal transmitted at the beginning of each scanning line (during the blanking period) of a composite video signal or the ''C'' component of a Y/C signal. It is used for color synchronization and to establish a reference for the color information following it. The color burst is an amplitude and phase reference for both color hue and color intensity. It is transmitted at the DC voltage level which is practically the black level of the signal. The luminance signal, which follows the color burst, should not fall below the color burst level. Black level clamping is usually performed in the color burst area.

Grammar Engineering Frequently Asked Questions
How do I constrain something to be not of a certain value?
The tdl formalism does not include any explicit negation operator. However, in most cases, you can use the logic of the type hierarchy to encode negative constraints.
For example, suppose your language has three cases, nominative, accusative, and dative, and that you want to constrain the value of CASE on some type to be not dative. Within this closed system, not dative is the same as nominative or accusative. Therefore, it suffices to define an intermediate supertype for nominative and accusative, which excludes dative:
case := *top*.
dat := case.
nom+acc := case.
nom := nom+acc.
acc := nom+acc.
Given this hierarchy, "The case is not dative" (equivalently, "The case is nominative or accusative") can be expressed thus:
[ CASE nom+acc ].

Title: Temperature-dependent phase-specific deformation mechanisms in a directionally solidified NiAl-Cr(Mo) lamellar composite
Phase-specific thermal expansion and mechanical deformation behaviors of a directionally solidified NiAl–Cr(Mo) lamellar in situ composite were investigated by using real-time in situ neutron diffraction during compression at elevated temperatures up to 800 °C. Tensile and compressive thermal residual stresses were found to exist in the NiAl phase and Crss (solid solution) phase, respectively. Then, based on the evolution of lattice spacings and phase stresses, the phase-specific deformation behavior was analyzed qualitatively and quantitatively. Moreover, estimates of phase stresses were derived by Hooke's law on the basis of a simple method for the determination of stress-free lattice spacing in in situ composites. During compressive loading, the NiAl phase yields earlier than the Crss phase. The Crss phase carries much higher stress than the NiAl phase, and displays consistent strain hardening at all temperatures. The NiAl phase exhibits strain hardening at relatively low temperatures and softening at high temperatures. During unloading, the NiAl phase yields in tension whereas the Crss phase unloads elastically. Additionally, post-test microstructural observations show phase-through cracks at room temperature, micro cracks along phase interfaces at 600 °C and intact lamellae kinks at 800 °C, which is due to the increasing deformability of both phases as temperature rises.

This Montgomery County farmstead was established by the locally prominent Earhart family. The property was among the holdings of George Earhart (born ca. 1773), and the complex was probably built around 1856 by Earhart for his son Henry (born ca. 1838) as he came of age. Land tax records show that the Earhart Farm tract acquired improvements valued at $2000 in that year. The frame, center-passage Earhart House has an element of sophistication with the use of a pilastered and paneled wall under the porch, a treatment similar to that at Solitude on the Virginia Polytechnic Institute campus. Purely vernacular, however, is the log kitchen nearby, an important example of a domestic outbuilding of the period. Perched on a slope, the kitchen at Earhart Farm has a limestone foundation forming a storage cellar. The exposed logs preserve early mud and wood chinking and traces of exterior whitewash.
The Earhart House was listed in the registers under the Prehistoric and Historic Resources of Montgomery County MPD.
Many properties listed in the registers are private dwellings and are not open to the public, however many are visible from the public right-of-way. Please be respectful of owner privacy.

Gamut mapping
What is color gamut?
Color Gamut is the range of colors a given color space can produce. Some color spaces (e.g. Lab, LCH, Jazbz, CAM16) are mathematical models that encompass all visible color and thus, do not have a fixed gamut. Others however cannot produce all visible color without values out of range. For example. all the RGB spaces (sRGB, P3, Adobe® RGB, ProPhoto, REC.2020) have a gamut that is smaller than all visible color. Therefore, there are visible colors that cannot be represented by certain color spaces. For example, the P3 lime (color(display-p3 0 1 0)) is outside of the gamut of sRGB. In addition, colors that are not visible to humans can sometimes be represented by some color spaces! Most notably, two of ProPhoto's three primaries (pure green, pure blue) are outside the gamut of human vision!
The process of transforming a color outside of a given gamut to a color that is as close as possible but is inside gamut is called gamut mapping and is the subject of entire books.
So how does Color.js handle all this?
Color.js does not do gamut mapping by default, as this is lossy: If you convert from a larger color space to a smaller one and then back, you need to be able to get your original color (possibly with some roundoff error due to the calculations).
You can call color.inGamut() to check if the current color is in gamut of its own color space, or you can pass a different color space to check against:
let lime = new Color("p3", [0, 1, 0]);
let sRGB_lime ="srgb");
Note that while the coordinates remain unchanged, the string representation of a Color object is, by default, after gamut mapping, unless you explicitly turn that off:
let lime = new Color("p3", [0, 1, 0]).to("srgb");
lime.toString({inGamut: false});
If you want gamut mapped coordinates, you can use color.toGamut(), which by default returns a new color that is within gamut (if you want to mutate your own color instead you can use {inPlace: true}). You can also pass a different color space whose gamut you are mapping to via the space parameter.
let sRGB_lime ="srgb");
lime.toGamut({space: "srgb"});
Perhaps most important is the method parameter, which controls the algorithm used for gamut mapping. You can pass "clip" to use simple clipping (not recommended), or any coordinate of any imported color space, which will make Color.js reduce that coordinate until the color is in gamut.
The default method is "lch.chroma" which means LCH hue and lightness remain constant while chroma is reduced until the color fits in gamut. Simply reducing chroma tends to produce good results for most colors, but most notably fails on yellows:
Here is P3 yellow, with LCH Chroma reduced to the neutral axis. The RGB values are linear-light P3. The color wedge shows sRGB values, if in gamut; salmon, if outside sRGB and red if outside P3. Notice the red curve goes up (so, out of gamut) before finally dropping again. The chroma of P3 yellow is 123, while the chroma of the gamut-mapped result is far to low, only 25!
Instead, the default algorithm reduces chroma (by binary search) and also, at each stage, calculates the deltaE2000 between the current estimate and a channel-clipped version of that color. If the deltaE is less than 2, the clipped color is displayed. Notice the red curve hugs the top edge now because clipping to sRGB also means it is inside P3 gamut. Notice how we get an in-gamut color much earlier. This method produces an in-gamut color with chroma 103.


Why Are the Barn Swallows & Dragonflies Swarming?
Why Are the Barn Swallows & Dragonflies Swarming?
-•• passion4nature/iStock/GettyImages
When you step out onto your lawn in the summertime, you're likely to notice the warm sunshine, the birds chirping and a dragonfly or two flitting through the sky. But occasionally, you might notice unusually large numbers of dragonflies swarming. So much so that you might ask yourself, 'Why are there so many dragonflies in my yard?' The same can also be said for the swift-flying barn swallows.
Both of these creatures move quickly on the wing, but that's about where their similarities seemingly end. However, you might be surprised to find that dragonflies and barn swallows often congregate in large numbers for the exact same reason!
Why Do Dragonflies Swarm?
Dragonflies have a voracious appetite and incredible skill in the air to match. These creatures are one of the most lethal hunters on the planet – if you're a small insect, that is! Adult dragonflies can skillfully capture a wide range of insect prey straight out of the sky, including butterflies, mosquitoes, flies and moths.
This prey preference helps answer the question 'Why do dragonflies swarm?' During warm, sunny days, dragonflies congregate in their preferred hunting grounds of meadows, open fields and areas close to the water to hunt their abundant insect prey. When food is aplenty, you'll find many dragonflies taking advantage of the feast.
Why Do Barn Swallows Swarm?
A graceful and agile barn swallow in flight is a sight to behold. These birds have skillful flying abilities similar to dragonflies because they feed on the same type of prey! Barn swallows readily hunt for mosquitoes, moths, bees and butterflies. Just like dragonflies, when insect prey is plentiful you're likely to find plenty of barn swallows flying in search of it above grassy fields and meadows.
When Do Dragonflies and Barn Swallows Swarm?
Whether you're watching a barn swallow flying along the tree line at your local park or a dragonfly zipping above your rhododendrons after mosquitoes, prey activity increases around the same time for both dragonflies and barn swallows. This means that both dragonflies and barn swallows can swarm around the same time when their insect prey is at its peak in population numbers.
For example, mosquito populations are highest during the warm, humid months of the summertime, particularly in regions with colder winter seasons. Mosquito populations also boom after periods of heavy rainfall, when humidity levels increase and standing water makes favorable breeding habitats plentiful. More mosquitoes mean more food for dragonflies and swallows!
A Bit of Friendly Fire
Because both of these creatures hunt the same type of prey, it might not surprise you to find that dragonflies and barn swallows can cross paths from time to time during their search for prey. Unfortunately for the dragonflies, barn swallows aren't particular about their meals and are more than happy to scoop up a dragonfly snack, fellow insect predator or not!
In the battle between dragonfly and barn swallow, the dragonfly still puts up a fair fight – or rather, flight. Though they might not have the ability to fend off the larger barn swallow, dragonflies can certainly hold their own in a flying contest. Their best bet for survival is outmaneuvering the barn swallow and hoping they have the upper hand (or wing) in their flight skills!
Do Barn Swallows Migrate?
Another important consideration in the swarming of barn swallows is their yearly migratory patterns. Not only do swallows migrate, but barn swallows travel across long distances to do so. As wintertime approaches and the weather cools, barn swallows in North America begin to congregate and fly south for warmer over-wintering grounds. They spend their winter in Central and South America before returning to North America in the spring.

Shutterbugs Wiggle and Stomp is a new free iPad app produced by the Smithsonian. The purpose of the game is to help children recognize the movements of animals. In the game children move through a virtual zoo with a zoo keeper. As they go through the virtual zoo the zoo keeper will ask students to take pictures of animals who are demonstrating running, jumping, stomping, and other movements.
Shutterbugs Wiggle and Stomp could be a fun little game for pre-K and Kindergarten students. The game reads the commands displayed on the screen to help students learn to read the words they're seeing. At the conclusion of the game students can print coloring pages of animals they took pictures of during the game.
