Platform: Java
Application code: Upload Your code
Before you upload your code you will need to export it as a JAR file. Go inside your application folder and type the following command:
./mvnw package -DskipTests
After it runs, upload the file hello-world-0.0.1-SNAPSHOT.jar under the target folder.
When the upload completes, click on the Create application button. AWS will start to create the environment, displaying the logs of what is happening in the process.
Once the environment is set up, AWS will redirect you to the Dashboard. Above the dashboard menu, you'll find the URL to access the application. Open it in a new tab, and it will load your web page.
Right now, you get a 502 error response, which is expected. By default, Elastic Beanstalk runs the application on port 5000, while Spring Boot executes on port 8080. Let's direct your app run on port 5000 to fix the issue.
Click on Configuration the dashboard menu. You will see the screen below:
You can change many variables and features in your environment: add a load balancer, increase the number of instances, or in this case add environment variables.
Go to the Software card and click on Modify. Look for Environment properties and add the following value to the list:
SERVER_PORT : 5000
After changing it, click on the Apply button and wait for AWS to apply the changes in the environment. When the message Environment update completed successfully. appears, open the URL again.
Now it worked! Type the username and password you defined in your code, john.doe and secret. It will then redirect you to the hello page, which will show you the same result as your local environment:
Hello, john.doe!
If you have problems, you can always check the logs.
 - In the menu, click on Logs, which will redirect you to the following page:
 - Go to Request Logs > Full Logs. This will generate a zip file with all your environment logs
 - Download and extract the file
 - Go to var/log/rotated
 - Over there you'll find another zip file from your app. Extract it, then open the extracted file to see the applications logs
Did everything work so far? Congratulations, you have your first Spring Boot application running in the cloud! Awesome, isn't it? But wait, you still have work to do before you can celebrate.
Make Your Application Security Production-Ready
Remember you created a user and put the credentials inside your code? This strategy might work for testing purposes, but it's a huge no-go for real applications.
Handling identity management is not a trivial task, and you'll want to use a service instead of "rolling your own".
Okta is an excellent identity management service, which provides an identity provider, authentication, authorization and user security out of the box. Let's configure your application to use it.
 - Select Web and click on the Next button.
 - Fill in the following options into the form:
Name: hello-world
Base URIs: http://localhost:8080/, ${BEANSTALK_URL}
Login redirect URLs: http://localhost:8080/login/oauth2/code/okta, ${BEANSTALK_URI}/login/oauth2/code/okta
Grant Type allowed: Client Credentials. Authorization Code
Change ${BEANSTALK_URL} to your AWS environment URL. For instance, my value is HelloWorld-env.t3z2mwuzhi.us-east-1.elasticbeanstalk.com.
Great! You whitelisted your local and production environments. If you make calls to your Okta application from them, it will permit the request.
Secure The Application With Okta and OAuth 2.0
With your application in Okta, you need to change the code to start using it. Okta handle the authentication for you from now on.
Replace the Spring Security dependency inside your pom.xml file with the okta dependency, which itself includes Spring Security. Put the following code inside the <dependencies> tag:
<dependency>
 <groupId>com.okta.spring</groupId>
 <artifactId>okta-spring-boot-starter</artifactId>
 <version>1.2.1</version>
</dependency>
The library will handle the communication between your application and Okta. All that you have to do is identify your Okta information. Set the following environment variables locally:
OKTA_OAUTH2_ISSUER={ORG_URL}/oauth2/default
OKTA_OAUTH2_CLIENT_ID={CLIENT_ID}
OKTA_OAUTH2_CLIENT_SECRET={CLIENT_SECRET}
Great! You whitelisted your local and production environments. If you make calls to your Okta application from those places, it will permit the request.
Your {ORG_URL} will be visible in your Okta dashboard, just click on Dashboard in the menu. You will see the Org URL in the right upper corner.
You can find {CLIENT_ID} and {CLIENT_SECRET} in your Okta application:
 - In your Okta's menu, go to Applications
 - Select the hello-world application
 - Click on the General tab
 - Scroll down to Client Credentials
There you'll see both the client id and secret.
With these changes, you now authenticate with OpenID Connect. When the user goes to the homepage, your application will redirect her to your Okta login page, then back to webpage.
OpenID Connect is a thin layer on top of the OAuth 2.0 authorization framework and is focused on identity and authentication.
With OpenID Connect, you need to change the way you receive the authenticated user. Go to the HelloWorldController class and update the code:
@Controller
public class HelloWorldController {
 @GetMapping({"/", "hello"})
 public String helloWorld(Model model, @AuthenticationPrincipal OidcUser user) {
 model.addAttribute("name", user.getGivenName());
 return "hello-world";
 }
}
This still passes authentication information to Thymeleaf using the model, but moves from using Principal to use OidcUser. This allows you to retrieve any attribute you want. In this example, we want the given_name attribute.
NOTE: Since you are using Okta to authenticate, you don't need your old configuration anymore. Go ahead and delete the SecurityConfiguration class.
Let's run the application! Start it again and go to http://localhost:8080/. Notice you're redirected to the Okta login page:
If you supply your username and password, you are redirected to the / endpoint. In my case, I'll see the following message:
Hello, Daniel!
Now you have a secure web application! The best part: you didn't have to worry about implementing authentication yourself.
Redeploy the Application on AWS Elastic Beanstalk
You have a production-ready application, so let's send it to your production environment! Log in to the AWS Console, and go to your Elastic Beanstalk environment.
 - Select the environment you created in the previous steps.
 - In the menu, click on Configuration
 - Press the Modify button inside the Software card.
Add the same environment variables you used in your local environment:
OKTA_OAUTH2_ISSUER={ORG_URL}/oauth2/default
OKTA_OAUTH2_CLIENT_ID={CLIENT_ID}
OKTA_OAUTH2_CLIENT_SECRET={CLIENT_SECRET}
After making the changes click Apply.
The last step is to update the application to the latest version. Go inside your project folder, and type:
./mvnw package -DskipTests
This command generates a JAR file with the current version of your application. Go to the AWS Elastic Beanstalk dashboard, and click on the Upload and deploy button. Select the file aven created (such as hello-word-0.0.1-SNAPSHOT.jar), and click on the Deploy button.
To make sure it is working, click on the AWS Elastic Beanstalk URL. It will redirect you to the Okta's login if you haven't logged in. When you enter valid credentials, it will redirect you to the Hello World page! In my case, the result will be:
Hello, Daniel!
Congratulations! You have deployed an application in the cloud and handled security the right way.

Adjaruli Khachapuri - Gastro Obscura
Prepared Foods
Adjaruli Khachapuri
Economists use this cheesy bread as a metric for cost of living between Georgian cities.
Georgians make khachapuri (pronounced "hatch-ah-POO-ree") all across the country. This cheese bread is so popular that economists at Tbilisi State University actually use the dish as a metric for inflation and cost of living between cities. They divide the average household income by the "Kh-index" (the cost of ingredients, as well as energy like gas or electricity, needed to produce one Imeretian-style khachapuri in a given city). This reveals how many servings the average family can afford to make in each city.
Despite the ubiquity of khachapuri, the details of this dish vary by region. It can be double-crusted, round, square, cheese-topped, or cheese-filled. Georgians incorporate a wide array of cheeses and doughs, and will cook it on a stovetop or in the oven. Some versions contain bitter greens or boiled potatoes, while others are filled with whole eggs.
Adjaruli khachapuri, hailing from the Adjara region on the coast of the Black Sea, has three distinct features: an open-faced boat shape, a raw egg, and a pat of butter on top. Adjarians fill their bread boats with sulguni, a brined cow cheese that's a little bit sour and salty, with the elasticity of mozzarella. Even better, the Kh-index indicates that Adjara is on the up and up. More boat-shaped cheese breads all around!
Need to Know
To properly eat Adjaruli khachapuri, mix the yolk and butter into the melted cheese, then rip off chunks of the bread boat to scoop up the insides. Think of it as an all-in-one fondue.

text: An epigram is a short, succinct poem, often with witty (or even vicious) content. Coleridge wrote an epigram to define an epigram: "What is an epigram? A dwarfish whole, / Its body brevity and wit its soul." It is worth noting that this is a stricter definition than epigrams seem to have had in classical Greece and Rome, where the form originates; it is probably the eighteenth-century fondness for a smart wit and the epigrams of Martial that tightened the definition thus. The preference in contemporary poetry for exploring an issue rather than summing it up means epigrams are not as popular as they were then, but Anne Stevenson's 'On Going Deaf', with its wit, rhyme and definite opinion, is probably the closest example within the Archive.

An Indigenous elder from far south-western Queensland says tourists love traditional stories about Aboriginal heritage in the Simpson Desert.
Don Rowlands from Birdsville has started taking visitors to a culturally significant site on the edge of town, known as 'Two Boys Dreaming'.
He says the site tells the story of how native wells were formed across the desert and it is important it is shared.
"I think what we tend to do as Aboriginal people is to not tell our story and I think that has been one of the mistakes we've made in the past is not telling our stories to the people but at the same time we expect them to understand us," he said.
"Now by telling the story, people get to understand why Aboriginal people want to protect places across the landscape."
He says tourists have appreciated visiting the site of two rocky outcrops on the edge of the town and hearing a story that has been handed down through generations.
"We have an area down here called Two Boys Dreaming - it's an Aboriginal site obviously which tells a story about how the country or the place was created," he said.
"The story is really about how the water wells were created in the Simpson Desert - two boys came across the desert and on their way they created these native wells so my ancestors could walk across the desert and have water."

A semiquantitative theory aimed to describe the adhesion kinetics between soft objects, such as living cells or vesicles, has been developed. When rigid bodies are considered, the adhesion kinetics is successfully described by the classical Derjaguin, Landau, Verwey, and Overbeek (DLVO) picture, where the energy profile of two approaching bodies is given by a two asymmetrical potential wells separated by a barrier. The transition probability from the long-distance to the short-distance minimum defines the adhesion rate. Conversely, soft bodies might follow a different pathway to reach the short-distance minimum: thermally excited fluctuations give rise to local protrusions connecting the approaching bodies. These transient adhesion sites are stabilized by short-range adhesion forces (e.g., ligand-receptor interactions between membranes brought at contact distance), while they are destabilized both by repulsive forces and by the elastic deformation energy. Above a critical area of the contact site, the adhesion forces prevail: the contact site grows in size until the complete adhesion of the two bodies inside a short-distance minimum is attained. This nucleation mechanism has been developed in the framework of a nonequilibrium Fokker-Planck picture by considering both the adhesive patch growth and dissolution processes. In addition, we also investigated the effect of the ligand-receptor pairing kinetics at the adhesion site in the time course of the patch expansion. The ratio between the ligand-receptor pairing kinetics and the expansion rate of the adhesion site is of paramount relevance in determining the overall nucleation rate. The theory enables one to self-consistently include both thermodynamics (energy barrier height) and dynamic (viscosity) parameters, giving rise in some limiting cases to simple analytical formulas. The model could be employed to rationalize fusion kinetics between vesicles, provided the short-range adhesion transition is the rate-limiting step to the whole adhesion process. Approximate relationships between the experimental fusion rates reported in the literature and parameters such as membrane elastic bending modulus, repulsion strength, temperature, osmotic forces, ligand-receptor binding energy, solvent and membrane viscosities are satisfactory explained by our model. The present results hint a possible role of the initial long-distance -> short-distance transition in determining the whole fusion kinetics.

What kind of mushroom did I find in Alabama?
If you spend time outside, you've probably asked this question at least once. Mushrooms are incredibly common in Alabama, and they come in all shapes, sizes, and colors.
Believe it or not, there are THOUSANDS of different types of mushrooms that live in Alabama. Since it would be nearly impossible to write about them all, I focused on the most common types that are seen.
IMPORTANT: You should NEVER eat a mushroom you find. There are many poisonous types, and some species will kill you. So stay safe, and don't eat any wild mushrooms unless you are with a mycologist (mushroom expert)!
15 COMMON MUSHROOMS in Alabama:
#1. Turkey-tail Mushroom
- Trametes versicolor
- Caps are up to 8 cm (3 in) long and 5 cm (2 in) wide.
- Rings of different colors decorate the tops, ranging from black to shades of brown and white.
- They often grow in a stacked pattern, which makes them look like roof tiles.
This species is one of the most common mushrooms in Alabama!
Turkey-tail typically grows on logs of deciduous trees. It's found in mature forests where dead trees on the forest floor make a perfect environment for this fungus.
This multicolored fungus is easy to spot thanks to the concentric rings of different colors on its caps. The growing pattern of Turkey-tail is also recognizable by the way it grows in a stacked pattern that looks like roofing tiles.
Like many mushrooms, Turkey-tail is used in Eastern medicine and as an herbal supplement. However, wild specimens should NOT be consumed or handled, and supplements containing this mushroom are not FDA-approved.
#2. Common Greenshield Lichen
- Flavoparmelia caperata
- This lichen grows in roughly circular patterns with wavy edges.
- The coloring is pale green to yellowish.
Common Greenshield Lichen is technically not a mushroom, but instead, it is a lichen. Lichens are complex organisms made up of both fungi and algae. The combination of these two types of organisms allows lichens to live in diverse climates, ranging from cool, dry areas to warmer regions with humid weather.
As a result, you can find Common Greenshield Lichen across Alabama. It most often grows on tree bark, although you might occasionally find it on rocks. Look for a rounded, pale-green growth with wavy edges.
#3. Splitgill Mushroom
- Schizophyllum commune
- The caps are 1–4 cm (0.3–1.6 in) wide.
- They are pale white or gray and grow in stacked clusters that resemble shelves.
- As its name suggests, the gills of this mushroom are spaced apart like individual threads.
Splitgill Mushrooms in Alabama thrive on decaying trees during rainy periods.
These tough, leathery mushrooms were once thought to be nonpoisonous. However, recent research shows they're often linked to fungal infections of the lungs. Symptoms can include breathing problems, prolonged cough, and other respiratory ailments.
Interestingly, this is one of the few mushrooms that grow abundantly in tropical weather. It thrives in heat and humidity thanks to its rubbery, tough structure. Fleshy, sponge-like mushrooms quickly rot, whereas this species lasts much longer.
Even though Splitgill Mushrooms are not poisonous, it's best not to consume any you find in the wild. The unprocessed fungus can cause lung infections, and this mushroom can be confused with more dangerous species.
#4. Crowded Parchment
- Stereum complicatum
- Individual caps are about 2 cm (0.8 in) across.
- This fungus grows in clusters of irregularly shaped semicircles, circles, and crescents.
- Its coloring is varying shades of brown and orange. It resembles crumpled pieces of paper.
Crowded Parchment is commonly found on dead oak trees. This inedible mushroom in Alabama helps with breaking down dead trees. It's easily recognized by the way it resembles crumpled paper.
However, despite being easy to find, this is one mushroom you'll want to leave alone. While it isn't considered poisonous, Crowded Parchment is often found near jelly fungus or algae, which can harm humans.
Instead of handling this mushroom, take photos to appreciate its complex structure.
#5. Pear-shaped Puffball
- Apioperdon pyriforme
- The cap portion is 1.5-4.5 cm (0.6-1.8 in) wide by 2-4.5 cm (0.8-1.8 in) tall.
- Their coloring is off-white with brown spots that are dense toward the middle of the cap and spread out at the edges.
- Most specimens are pear-shaped, but they are often spherical as well. They grow in clusters of 4-10 caps.
Look for these mushrooms in Alabama on rotting logs.
Pear-shaped Puffballs are commonly found during their long fruiting season, which lasts from July to November. They are nonpoisonous.
However, Pear-shaped Puffballs look similar to several dangerous species of poisonous mushrooms. For example, a lookalike called the Earthball mushroom can cause gastrointestinal distress, fever, and eye infections.
It's better to purchase Pear-shaped Puffballs from an expert or forage with someone who knows what they're doing. If not, you may end up sick.
#6. Violet-toothed Polypore
- Trichaptum biforme
- The caps are 1-7.5 cm (0.4-3 in) wide.
- Their shape is an irregular semicircle, similar to a seashell.
- The coloring of this fungus is shades of brown with violet, purple, or lavender rings near the edges.
If you spot a mushroom in Alabama that looks like a clamshell, it's likely a Violet-toothed Polypore! This species can be identified by its shell-like shape and striped purple coloring. It grows in stacked clusters on rotting logs.
Interestingly, Violet-toothed Polypore is known to only grow on decaying aspen and poplar trees. So, if you live near a forest with those species, you'll likely find this mushroom!
Keep pets away from this species, as it's particularly poisonous for dogs. It can cause stomach problems and dehydration. Violet-toothed Polypore is also inedible to humans.
#7. Green-spored Parasol
- Chlorophyllum molybdites
- The caps are 8-30 cm (3-12 in) in diameter.
- This mushroom is white or off-white with irregular brown spots and warts.
- The gills are visible around the edges of the top and very prominent on the underside.
This is the most frequently eaten poisonous mushroom in Alabama!
Green-spored Parasols bear an unfortunate resemblance to several edible fungi, which means it's often eaten by mistake. In addition, this fungus causes severe stomach symptoms such as vomiting, diarrhea, and colic.
Unfortunately, this mushroom is common on lawns and in pastures, which puts children and pets are at greater risk for poisoning. Please keep them away from these mushrooms!
Green-spored Parasols grow directly from the ground instead of from tree logs or other decaying wood. We recently had a cluster pop up after we had new mulch put down. The spores are often present in soil or mulch and can remain dormant until the next fruiting season.
#8. Oyster Mushrooms
- Pleurotus ostreatus
- The caps are 2–30 cm (0.8–12 in) wide.
- They are fan-shaped with thick stalks and grow in a stacked pattern or irregular clusters.
- Their coloring is often white or off-white, sometimes with a light purple or gray wash.
You can find Oyster Mushrooms in Alabama both in the wild and on farms.
These mushrooms are often used as food and are commercially farmed worldwide. In fact, they were first cultivated in Germany during World War I to mitigate hunger because of rationing. As a result, you can find these mushrooms in most grocery stores, so eat those instead of a wild variety!
Something most people don't know is that Oyster Mushrooms are carnivorous! This species eats nematodes that you might know as roundworms. They paralyze and consume the nematodes as a source of protein and nitrogen. Additionally, Oyster Mushrooms help to decay dead trees.
Pearl Oyster Mushrooms are also dried and used as a leather-like material or compressed into a wood substitute to make furniture. Mycelium, which is the fiber that gives Oyster Mushrooms their structure, is incredibly strong and resilient. Check out this page for more info!
#9. Ringless Honey Mushroom
- Desarmillaria caespitosa
- The caps are 2.5-10 cm (1–4 in) wide.
- Their coloring is light brown to pale yellow with white stalks.
- These mushrooms often grow in large clusters.
Ringless Honey Mushrooms in Alabama are often confused with other species.
For example, they look similar to Honey Mushrooms (Armillaria mellea), except they don't have a dark ring around the stalk. Unfortunately, they also imitate the Galerina Mushroom, which is deadly if ingested.
Ringless Honey Mushrooms are parasitic to the trees on which they grow. Eventually, the tree will stop producing leaves and die due to the fungal infection. They will infect various trees, from conifers to broad-leafed hardwood trees.
#10. Witch's Butter
- Tremella mesenterica
- Fruiting bodies can be up to 7.5 cm (3

Construction of the Qinghai-Tibet railway has not polluted the source of the Yangtze River, which is in the project area.
According to a water quality and environment survey by the Qinghai Provincial Environment Monitoring Center, the water quality at the source of the Yangtze, the longest river in China, has remained unchanged.
The center has regularly monitored and tested water quality in the area since the railway project began in June last year.
The Qinghai-Tibet railway, running for 1,142 km from Golmud in Qinghai Province to Lhasa in the Tibet Autonomous Region, is the longest and most elevated railway built on highlands in the world. It will be the first railway linking Tibet with the rest of China.
A total of 960 km of the railway will be laid in area with an elevation of more than 4,000 meters.
Workers with the Qinghai Provincial Environment Monitoring Center tested 15 items, including heavy metals, suspended substances and biochemical oxygen consumption in the water in the upper and lower reaches of the Yangtze River and its tributaries.
They also monitored the water quality of the Golmud, Sancha and Xueshui, snow water, rivers and found no visible changes.
Lu Chunfang, director of the project's headquarters, said they have worked out administrative measures for protecting the local environment during the construction of the railway, aiming to keep the effects on the local environment to a minimum.
In April, the Qinghai-Tibet railway construction headquarters and construction teams signed an agreement with Qinghai Provincial Environmental Protection Bureau for each of the involved work units to take its due responsibility in protecting the local environment.
The agreement is said to be the first of its kind in the railway construction history of China.
The construction team in charge of building a large bridge at the source of the Yangtze River handles various kinds of garbage carefully. Degradable garbage is buried deep underground and that which is not degradable is disposed of at Golmud more than 400 km away. Effective measures have been taken to prevent soil erosion and polluting water sources during construction.
Use of phosphorus-free scouring is encouraged both in the residential camps and at the construction site. The wastewater is disposed of timely and then used for watering trees and grass.

Vatican City, Jul 19, 2018 / 23:00 pm
After publishing a highly controversial essay in July 2017 alleging the existence of an "ecumenism of hate" between Catholics and Evangelicals in the U.S., close papal confidantes Fr. Antonio Spadaro SJ and Marcelo Figueroa in a new article issue a scathing critique of the "prosperity gospel," which they say is based on a reductionist view of the American Dream.
In the new essay, run July 18 in the Jesuit-run magazine "La Civilta Cattolica," which is directed by Spadaro, the authors argue that the prosperity gospel, rooted in late 19th century America, is closely tied to the Protestant Evangelical movement in the U.S., and sees power, wealth and success as the result of one's faith, while poverty and misfortune are signs of a lack of faith.
"The risk of this form of religious anthropocentrism, which puts humans and their well-being at the center, is that it transforms God into a power at our service, the Church into a supermarket of faith, and religion into a utilitarian phenomenon that is eminently sensationalist and pragmatic," they said.
Spadaro and Figueroa, a Protestant who heads the Argentine section of Vatican newspaper L'Osservatore Romano, said the prosperity gospel is "a reductive interpretation" of the American Dream.


Swiss Empa scientists and their colleagues have spent four years studying the potential of sodium hydroxide (NaOH) to store heat from the warmth of summer into the cold of winter.
The theory behind this kind of heat storage is fairly straightforward: if you pour water into a beaker containing solid or concentrated sodium hydroxide (NaOH), the mixture heats up. The dilution is exothermic where chemical energy is released in the form of heat. Moreover, the sodium hydroxide solution is highly hygroscopic and able to absorb water vapor. The condensation heat obtained as a result warms up the sodium hydroxide solution even more.
Heat exchangers from instant water heaters provided the solution: the sodium hydroxide solution. Spirals along a pipe, absorbs water vapor and emits heat. Image Credit: Empa. Click image for the largest view.
We are still far from a sustainable energy supply. In Switzerland during 2014, 71 percent of all privately-owned apartments and houses were heated with fossil fuels, and 60 percent of the hot water consumed in private households is generated in the same way. In other words, a considerable amount of fossil energy could be saved if we were able to store heat from sunny summer days until winter time and retrieve it at the flick of a switch.
Materials capable of storing heat include those such as bricks or concrete that slowly release the stored heat, and others such as water or ethylene glycol that take in heat when they transform from a solid to a liquid. However, none of these materials can store heat energy over a long period as they simply naturally release it slowly over time. A material that could store heat energy for a long time and release it at the exact timing desired would be a boon for the field of renewable energy.
Is there a way to do this? It certainly looks like the Swiss have it. Since autumn of 2016, following several years of research, Empa has a plant on a lab scale in operation that works reliably and is able to store heat for the long term. But the road to get there was long and winding.
When heat energy is fed into a dilute sodium hydroxide solution in the form of heat, the water evaporates, the sodium hydroxide solution will get more concentrated and thus stores the supplied energy. This solution can be kept for months and even years, or transported in tanks. If it comes into contact with water (vapor) again, the stored heat is re-released.
That's how the theory works. But could the beaker experiment be replicated on a scale capable of storing enough energy for a single-family household? The Empa researchers Robert Weber and Benjamin Fumey rolled up their sleeves and got down to work. They used an insulated sea container as an experimental laboratory on Empa's campus in Dübendorf – a safety precaution as concentrated sodium hydroxide solution is highly corrosive. If the system were to spring a leak, it would be preferable for the aggressive liquid to slosh through the container instead of Empa's laboratory building.
Unfortunately, the first prototype didn't work as anticipated. The researchers had opted for a falling film evaporator – a system used in the food industry to condense liquids, most commonly, orange juice into a concentrate. Instead of flowing correctly around the heat exchanger, however, the thick sodium hydroxide solution formed large drops. It absorbed too little water vapor and the amount of heat that was transferred remained too low.
Then Fumey had a brainstorm. The viscous storage medium should trickle along a pipe in a spiral, absorb water vapor on the way and transfer the generated heat to the pipe. The reverse – charging the medium – should also be possible using the same technique, only the other way round. The idea worked. And the best thing about it is the spiral-shaped heat exchangers are already available from existing inventory as the heat exchangers from flow water heaters.
Fumey then optimized the lab system further by asking which fluctuations in NaOH concentration are optimal for efficiency? Which temperatures should the inflowing and outflowing water have? Water vapor at a temperature of five to ten degrees C is required to drain the store. The water vapor can be produced with heat from a geothermal probe, for example.
During the heat recovery process a 50-percent sodium hydroxide solution runs down the outside of the spiral heat exchanger pipe and is thinned to 30 percent in the steam atmosphere. The water inside the pipe heats up to around 50º Celsius – which is just about right for radiant floor heating.
To recharge the heat inventory, the 30-percent, "discharged" sodium hydroxide solution again trickles down around the spiral heat exchanger pipe. But now inside the pipe flows 60º C hot water, which could be produced by a solar collector. Then the water from the sodium hydroxide solution evaporates; the water vapor is removed and condensed. The condensation heat is conducted back into a geothermal probe, where it is stored. The sodium hydroxide solution that leaves the heat exchanger after recharging is concentrated back to 50 percent again, i.e. "charged" with thermal energy.
Fumey said, "This method enables solar energy to be stored in the form of chemical energy from the summer until the wintertime, and that's not all. The stored heat can also be transported elsewhere in the form of concentrated sodium hydroxide solution, which makes it flexible to use."
The search for industrial partners to help build a compact household system on the basis of the Empa lab model has now begun. The next prototype of the sodium hydroxide storage system could then be used in Switzerland's NEST building innovation project.
There have been many attempts at heat storage over the years, most all too vulnerable in heat loss to justify the investment, Here the Swiss have a fully static storage. This concept might well get to market. There are many questions yet to ask and answer, but this looks very good indeed.

 Many people do not know that Bat Masterson – western sheriff and gunfighter – became a writer for Chicago Newspaper late in life. Your article reminded me of the unfinished editorial that Masterson was working on when he died.
 He wrote, "It has been my experience in life that everything evens out. Take Ice for instance. The Rich have Ice in the Summer and the Poor have Ice in the Winter. So, it all evens out."

 Hope scientists can find ways that can store heat from the warmth of summer into the cold of winter. That will be amazing!

Frequently in the course of carrying out their duties in law enforcement, it becomes necessary for police officers to stop a person and make an inquiry such as:
 - What is your name?
 - What is your address?
 - Do you have any identification?
The Frazeysburg Police Department strives to provide service to everyone in the community fairly and equally. Sometimes a very routine encounter may cause a person to feel intimidated or to respond in a manner which gives rise to conflict or suspicion. We hope that the information on this page will be helpful in explaining why an officer may have to stop and question a citizen and reduce elements of conflict when confronted by an officer. It will explain what to expect if a police officer stops you for questioning and also provide some guidelines on how to respond to the questioning process. You are cautioned, however, that this is not a legal advisory.
Why Question?
When law enforcement representatives question a person, there are underlying reasons. They may be checking on some complaint phoned into police by someone in the community. They may have received a report of some criminal activity which has just occurred in the area. Your presence might indicate that you are a potential witness who would be able to provide valuable information in an investigation. In some cases the officers' observations may lead them to think you are having trouble and need assistance.
Sometimes purely innocent behavior can be suspicious to police. For example, if you go for a night-time run, and you happen to run by a business that had an alarm go off in the past few minutes, you can see why police would be interested to know what you were doing. After a few questions and police being given the opportunity to examine the situation up front, the matter will be resolved.The best way for them to clarify the situation is to ask questions. With all due respect to citizens' rights, officers have a responsibility to properly investigate matters which may threaten public safety or involve breaking the law. Their questions are not necessarily an accusation, and your cooperative response can alleviate potential conflict. If officers just assumed everyone was obeying the law, crimes or violations of the law would never be stopped.
Police continually have to perform a balancing act - being conscious of your rights and your presumtion of innocence but also investigating crimes or possible crimes.
Using the example above, if you are a business owner who has been burglarized several times, and you bought an expensive alarm system to protect it, you would expect the police to check your business when it goes off. Certainly if it is night time, and you went to check on your business yourself, and you saw someone running away from it, you might think they just broke in and got scared by the alarm. You would probably call 9-1-1 and want that person stopped, especially if there was damage to your property.
If the Police Stop You on the Street
Sometimes problems arise when it seems as if a police officer has stopped to question you for what appears to be no reason at all. Rest assured, if the police are stopping you, there is a reason, allow the officer time to explain what is going on. Sometimes the time factor may be crucial in investigating a possible crime, police officers are trained to observe and evaluate a situation and to act if they have a reasonable suspicion that you may in some way be involved in an incident. We thank you in advance for your future cooperation to help us keep you and your property safe!

The Council for Scientific and Industrial Research (CSIR) has developed a lighter, cheaper and more compact version of its Otus surveillance camera, which is currently being used to detect poachers in the Kruger National Park.
The CSIR's new Tyto camera, which is a spinoff off Otus, is designed for wide area surveillance for applications like border security or asset protection. Whereas Otus has two channels of view, Tyto has one, making it lighter and cheaper – Tyto weights 20 kg compared to the 98 kg of Otus, and is 58 cm long compared to 80 cm.
Otus and Tyto are developed using commercial off the shelf optical components, enclosed in a custom housing. The system operates using software developed by the CSIR.
Tyto is able to operate during the day or at night with enhanced twilight performance. It has a high sensitivity monochrome main sensor and thermal detection sensor. The day camera has a 30 times optical zoom. Range is around 5 km, compared to approximately 10 for Otus.
Otus is the camera on the Meerkat wide area surveillance system that adds a Reutech radar. It has been used in the Kruger National Park to spot rhino poachers with considerable success. Like Otus, Tyto can also be integrated with a radar system.
At the moment the CSIR is doing feasibility testing of the camera system. While Otus is a mature product, Tyto is a niche market product still under development.
Aside from onsite laboratories and facilities used in the development of optronic products, the CSIR said it is geared to undertake pilot deployments in the field with mobile containerised control and evaluation units.
The CSIR said its cameras are ideally suited for day and night surveillance of high value assets, including for wildlife conservation, state-owned entities/infrastructure and border management.

Lost but Not Forgotten memorial plaque
A joint partnership between the Aboriginal community and Kempsey Shire Council has enabled dozens of unmarked graves to be acknowledged and remembered at the East Kempsey Cemetery. A special memorial plaque has been set in a large boulder at the cemetery and was unveiled on Tuesday, 19th December 2006.
The East Kempsey Cemetery was surveyed using non-destructive radar as part of the Council's action plan for reconciliation, and through consultation with the Dunghutti Aboriginal community the need for an appropriate memorial was established. Dozens of graves, some of which are up to 100 years old were detected through the survey. Due to the age of some of the graves, accurate marking of a precise site is near impossible, so a joint project between the community and Council has resulted in a fitting memorial boulder and plaque marking the area.
The boulder was chosen from Thurgood's Haulage at a quarry at Crescent Head through consultation with the Dunghutti Elders of the Booroongen Djugun Aboriginal Corporation, the Local Aboriginal Land Council, Council's Aboriginal Liaison Officer and Booroongen Djugun's community support officer. The NSW Department of Environment and Conservation assisted with funding of the plaque. Wording on the plaque was put together by the Elders and support officers.
This project marked a significant step forward in reconciliation in Kempsey and is seen as a fitting spiritual tribute to lost souls.

Stage 3 of this project, in consultation with the Dunghutti Aboriginal Community and particularly the Elders, the wording for the memorial Plaque.
Funding for the Memorial Plaque was contributed by the Department of Environment and Conservation Northern Aboriginal Heritage Region unit for site management and protection, through their Aboriginal Heritage and Conservation Project funding.
The memorial boulder was chosen through the consultation process and donated by David Thurgood of Thurgood Haulage Kempsey.
Debra Morris, Aboriginal Liaison Officer, Kempsey Shire Council and Amie McElroy, Aboriginal Community Support Officer, facilitated and supported the Dunghutti Aboriginal Community throughout this process.

This is an in depth article of how to identify Murray Grey cattle.
1Do a search on the Internet or in a cattle breeds book for "Murray Grey" cattle.
2Study the characteristics of the breed. Note the following:
- Coloration: Murray Grey cattle range from a light silvery grey to a dark grey, though the primary preferred coloration is silver grey. The skin should be heavily pigmented or dark colored as this keeps away problems such as sunburned udders and cancer eye. The genetic standpoint of the coloration of this breed is not well understood, since multiple gene effects make it difficult to get a true breeding condition. It is thought that in addition to the basic color genes that are involved, dilution or modifying genes also play a definite role in this color pattern inheritance.
- Body type and characteristics: They tend to be fine-boned but beefy, with the same muscling characteristics of a Shorthorn. They are a medium framed breed, similar in size to a medium-framed Angus, and do not get overly big like Continentals would.
- Head characteristics: They tend to have a small head in comparison to the rest of their body size. They are naturally polled as well, with head shape similar to that of an Angus.
Other characteristics: They are originated from New South Wales, Australia, where a roan Shorthorn cow was bred to a Black Angus bull and was found to produce only grey calves from this cross. Interest grew in this grey cattle, and they way they out-performed Angus and Shorthorns, and efforts continued to make this into a breed. Consequently, Murray Grey cattle excel in the feedlot as well as in the pasture on only grass, and butchers started paying a premium for Murray Grey beef. Popularity grew, and so did the breed. Today, they can be found not only in Australia, but also in the USA and Canada.
- They are also known for their small thrifty calves that grow like weeds once they hit the ground. Cows are great milkers as well, and this translates to great growths in the calves. They are highly adaptable, able to thrive and survive in a variety of climatic and environmental conditions, still keeping their condition and raising good calves. They are also very docile, which make them favorable in intensive grazing and feedlot conditions.
3Memorize the details and characteristics of this breed.
4Go on a field trip or road trip and see if you can find farms and ranches with Murray Grey cattle. Take pictures of what you thought were Murray Grey cattle, and compare them with pictures of Murray Greys in your cattle breeds book or on an Internet cattle breeds site.
- Try not to get Murray Grey confused with other composite cattle that can have the same grey coloration. F1 Charolais-Angus cross cattle can be grey in coloration too, since Charolais tend to also have a dilution gene when crossed with other breeds.
- Use the grey coloration as an indicator of this breed.


Kia Optima Hybrid: Air Conditioning System / Compressor Oil Repair procedures
Oil Specification
1.
The HFC-134a system requires synthetic (POE) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed.
2.
Compressor (POE) oil varies according to compressor model. Be sure to use oil specified for the model of compressor.
Since the electric compressor uses high-voltage, you should use POE oil which have high Volumetric Resistivity.
Do not use the same A/C recovery / charging station as conventional belt-driven compressors.

If the POE oil of the system gets mixed with PAG oil, then dielectric breakdown due to decreased volumetric Resistivity can occur and inoperative A/C compressor may result, A/C compressor may not work.
If the POE oil gets mixed with PAG oil, replace the compressor with new one and clean inside the A/C system (condenser, refrigerant line, evaporator and etc.)
Handling of Oil
1.
The oil should be free from moisture, dust, metal powder, etc.
2.
Do not mix with other oil.
3.
The water content in the oil increases when exposed to the air. After use, seal oil from air immediately. (HFC-134a Compressor Oil absorbs moisture very easily.)
4.
The compressor oil must be stored in steel containers, not in plastic containers.
Compressor Oil Check
The oil used to lubricate the compressor is circulating with the refrigerant.
Whenever replacing any component of the system or a large amount of gas leakage occurs, add oil to maintain the original amount of oil.
Oil total volume in system
POE OIL : 3.8 ~ 4.5 oz. (115 ~ 135cc)
Oil Return Operation
There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculation with the refrigerant in the system. When checking the amount of oil in the system, or replacing any component of the system, the compressor must be run in advance for oil return operation. The procedure is as follows:
1.
Open all the doors and the engine hood.
2.
Start the engine and air conditioning switch to "ON" and set the blower motor control knob at its highest position.
3.
Run the compressor for more than 20 minutes between 800 and 1,000 rpm in order to operate the system.
4.
Stop the engine.

(1) A term t is directly referential iff the semantic content of t is the designatum of t.
(2) The semantic content of a term t is X iff for every linguistic environment E, the semantic content that t contributes to E(t) is X [i.e Semantic Innocence].
(3) Thus, a term t is directly referential iff for every linguistic environment E, the semantic content that t contributes to E(t) is the designatum of t.
(4) In a bound environment (e.g. ∀xFx) a variable does not contribute its designatum (since 'Fx' must contribute a set of assignments).
(5) Thus, variables are not directly referential.
I'm interested in how people who advocate direct reference theory maneuver out of this argument. Denying either premise (1) or premise (2) are really the only options for not accepting the conclusion.
Premise (1) is an attempted definition of "direct reference". So perhaps I got the rough definition wrong. One alternative idea that would avoid the conclusion is this: a term t is "directly referential" iff the designatum of t is "directly" determined by the interpretation or assignment function, in the sense that its designatum is assigned independently of the world and time parameters. But to my ear this is a definition of rigidity de jure---it's a fact about a terms designatum across worlds/times and how it is built in by law that it be independent of worlds/times. Direct reference, however, is supposed to make a further claim about "semantic content". Kaplan defines it thusly: "When what is said in using an indexical in a context c is to be evaluated with respect to an arbitrary circumstance, the relevant object is always the referent of the indexical with respect to the context c." It's a familiar point that "direct reference" simply amounts to rigidity de jure, unless we construe it in terms of Russellian structured contents. But I'm not sure how one might want to tinker with the definition to avoid the conclusion.
In any case, I think the real action is with premise (2). And it seems that many will somehow want to deny it, and thus deny semantic innocence (e.g. see Salmon's "A theory of bondage", which develops a Fregean referential shift semantics for variable binding (although he doesn't exactly endorse the occurrence-based semantics he outlines)).
But if a term can be "directly referential" even though the value it contributes across all environments (i.e. its compositional semantic value) isn't its designatum, what is the significance of calling the term "directly referential"? For example, the direct reference theory of names is controversial precisely because of its commitments on embedded occurrences, e.g. names embedded in belief reports. (Perhaps this is where the distinction between Millianism and Direct Reference is important.) Can one accept that 'Hesperus' and 'Phosphorus' are directly referential (and thus have the same "semantic content" in some important sense) even though the semantic content of their occurrences in belief contexts are different? It's hard for me to get a grip on "semantic content", if it is detached from the semantic contribution an expression makes to the complex expressions of which it is a constituent.
I'm left wondering what "direct reference" is exactly and what important (and plausible) thesis about language it is committed to. Any ideas?

William Kelly, (born Aug. 21, 1811, Pittsburgh, Pa., U.S.—died Feb. 11, 1888, Louisville, Ky.), American ironmaster who invented the pneumatic process of steelmaking, in which air is blown through molten pig iron to oxidize and remove unwanted impurities. Also patented by Sir Henry Bessemer of Great Britain, this process produced the first inexpensive steel, which became the major construction material in the burgeoning industrial age.
In the early 1840s, while on a buying trip for McShane & Kelly, a Pittsburgh dry-goods and shipping company in which he was a partner, Kelly became interested in the iron industry around Eddyville, Ky., and later persuaded his brother to join him in forming an ironworks. They bought an iron furnace and 14,000 acres of timberland and ore deposits; the Eddyville Iron Works prospered.
With the gradual depletion of the timberland and the dwindling of carbon-free iron deposits, Kelly began searching for a more efficient means of refining pig iron. Aware that air drafts cause molten iron to glow white hot, he became convinced that air blown through molten iron not only would remove the carbon but also would cause the temperature of the molten mass to rise, making further heating unnecessary.
In 1855 Bessemer obtained an English patent, and the following year several American patents, on the pneumatic process. When Kelly heard of Bessemer's patents, he filed a priority claim and in 1857 received a U.S. patent superseding Bessemer's patents.
Further innovations in steelmaking, notably by Robert Mushet of England and Goran Goransson of Sweden, made the pneumatic process practical. Before he went bankrupt during the panic of 1857, Kelly sold his patent to his father. In 1859 he renewed his experiments at the Cambria Iron Works, Johnstown, Pa., and by 1862 managed to find enough financial aid to enable him to build a steel plant in Wyandotte, Mich. Within two years he produced the first commercial steel using the Kelly process. In 1863 the Kelly Pneumatic Process Company was organized, and the following year a rival company using Bessemer's patents was organized in Troy, N.Y. Unable to achieve more than minimal success with their respective patents and processes, the two companies pooled their resources in 1866, and thereafter steel production expanded rapidly.

Why do kissing gouramis kiss each other? Does this signify that I have a pair?
It seems most likely that this strange kissing ritual has actually
evolved as a way of settling disputes, without the fish having

Review: What Is Technic?
In this chapter, we sought to answer one simple question, "What is Technic?" You discovered that the answer really has two parts to it. First, you found out that Technic is a system within a system. It is a set of LEGO elements with unique and interesting features that can also work with the standard parts you've seen elsewhere in this book. Second, you saw that Technic is also a style of building with the specialized pieces that make up this class of parts. This could mean wheeled vehicles that have working steering or it could mean a small helicopter with rotor blades that turn when you give its tail a spin with your finger.
Defining Technic wasn't as easy as some of the other questions we've tackled in this text, but...

This paper presents a new acquisition method and the application of the technology for the acquisition of a person's foot. The sensor is designed to meet the requirements of measuring a variety of feet under various ambient optical conditions that can, in other circumstances, seriously affect the data measurements and reduce the reliability of the system. The most important distinction between this ranging method and other more classical approaches is the high tolerance of the method to external optical perturbations as well as reflections from other sensor heads. This allows its use in conventional "store" or "medical offices" that are usually bright places.

Oxalis triangularis, also called false shamrock, or love plant, has this last name particularly appropriate, as it is a uniquely beautiful plant that is especially striking when kept in optimal conditions. However, it is a somewhat climate-delicate plant and is not always easy to care for, especially if its needs are not known. Learn all about Oxalis triangularis care in this article.
In this article, we tell you everything you need to know about Oxalis triangularis plant care to keep your plant looking healthy, strong, and beautiful. Join us to learn more about the false shamrock!
Characteristics Of the Oxalis Triangularis Plant
This false shamrock has its origin in Brazil, particularly in cool areas of this huge South American country. It is a rhizomatous plant and its so-called bulbs keep the subway part of the plant alive in the cold months, leaving the aerial part to dry out and resprout again when conditions are optimal.
They are small in size, usually growing to about 8″ (20 cm) in height, and their most striking and identifying feature is their beautiful purple leaves, with stems so pale green that they seem almost white. These leaves look like butterflies resting when they are folded, but they have the ability to open or fold depending on the amount of light that reaches them, making this change in just a few hours, so they can adapt better and not receive more or less light than they need. Its pink or white flowers are small and drooping, and although they are pretty, they do not usually stand out more than the leaves.
While the plant is not dangerous on contact, planted in very large quantities it could be harmful to very young children. Likewise, if you have pets at home, make sure they do not eat it or rub against it too much, as it could be toxic to them.
Climate and Location to Care for Oxalis triangularis
One of the most important things when growing this plant is the climate it needs. Since it comes from cool areas of Brazil, where the thermal variation is small, it is a species that does not tolerate extreme temperatures, neither for heat nor cold and will react quite badly to any case of very high or very low temperature. Thus, the idea is to keep it always between 50°F (10 ºC) and 82°F (28 ºC), being able to withstand temperatures a little higher or lower, but always punctually. In winter, it will tolerate temperatures as low as 41°F (5ºC), but lower exposures will probably kill it.
With this in mind, it is normal that it tends to be grown as a potted houseplant, where it is much easier to control the environment to which it is exposed. If the climate suits its needs, it is also commonly grown as an outdoor potted plant, since planted in the soil it can act as an invasive plant.
In summer it can be taken out to terraces if the temperature is cool, in the same way, that in winter it can also be done if it is mild winters when the temperature does not drop below 41°F (5 ºC). In this way, the plant will enter in vegetative rest and will rest, to resprout in spring with recovered energies. If you have your butterfly plant indoors and you cannot give it vegetative rest, it is likely that the plant will weaken, although you can try to compensate with a little extra fertilizer.
- PRODUCT: Includes 20 bulbs per pack (Oxalis Triangularis). Please note that Oxalis bulbs are naturally smaller than a typical bulb.
- VERSATILE: As they're easy growers both in the ground and in containers, use this plentiful plant for edging, container gardens, or as indoor windowsill accents.
- FAST-GROWING: Expect the brilliant foliage to appear within 3-4 weeks of watering and delicate flowers in about 10 weeks.
Light to Care False Shamrock
Purple clover does well in semi-shade or direct sun if the sun is not too intense, although ideally it should receive plenty of light, always screened by a thin curtain or something similar. If it does not have enough light, the oxalis will have fewer leaves and its stems will be thinner, so it will be weaker and it will be easier for it to die from other deficiencies or from diseases or pests.
Watering False Shamrock
Except in its vegetative rest period, like all plants that do, the butterfly plant needs regular watering throughout the year.
The ideal frequency is to allow the top layer of the substrate to dry out between waterings so that the plant does not become thirsty but does not become waterlogged due to over-watering, which would rot its rhizomes. In the cold months, from the beginning of autumn, watering is suspended until spring, if rainwater is falling, although it is necessary to avoid too much.
Substrate and Fertilizer to Care for Oxalis triangularis
The Oxalis triangularis is not demanding in terms of its substrate, the only thing necessary being that it has good drainage. You can use a universal mixture with peat, coconut fiber, and worm humus in equal parts, to which you can then add vermiculite and perlite. This substrate is light, has ideal drainage and water retention properties, and is also very rich in nutrients and microorganisms beneficial to plants, so your Oxalis triangularis will develop perfectly.
Regarding the fertilizer, just add a little fertilizer monthly during the warm months, or a little organic matter such as compost or worm castings. I recommend you to read our article about clover fertilizer.
We hope this article on how to care for Oxalis triangularis will be useful and that you will enjoy this beautiful plant. We recommend our article about how to care for a wandering jew plant.

I've seen a lot of posts on ERP data migration, but they typically discuss what historical data should (or shouldn't) be loaded and the various tools for loading data. What seems to be missing is a simple explanation of the logic behind executing a financial cutover.
When you cutover from a legacy system, at a minimum you need to load the ending financial balances as well as the open transactions for each of the sub-ledgers.
The figure below illustrates how to manage a financial cutover.
The yellow box represents the trial balance from the legacy system and the blue boxes represent the open transactions for each of the sub-ledgers. Since the trial balance includes the sub-ledger balances, to avoid duplication you would typically point the sub-ledger balances from the trail balance to one or more clearing accounts. Then when you load the detailed open sub-ledger transactions, they offset the clearing account. At the end of the day, the clearing accounts should net to zero and the total of the detailed sub-ledger transactions should match the associated ledger account.
After executing all of the data loads, the business validates the data and confirms that the trail balance in Dynamics AX matches the ending trial balance from the legacy system.

The Silo Canal, or Silokanal in German, is a canal in the German state of Brandenburg. It provides a short cut for vessels navigating the River Havel, avoiding the winding and constricted navigation through the city of Brandenburg an der Havel.
The 5.26-kilometre (3.27 mi) long canal follows the route of the Silograben of 1782, and was constructed between 1907 and 1910. At its upstream end, the Vorstadtschleuse Brandenburg lock descends 1 metre (3 ft 3 in) into the lower level of the Havel, known as the Brandenburger Niederhavel, where a junction is also made with the Beetzsee. From here the canal proper skirts the northern edge of the city, eventually flowing into the Quenzsee, which links to the Plauer See and hence the River Havel and the Elbe–Havel Canal.
Whilst commercial shipping uses the Silo Canal, leisure traffic tends to use the older and smaller dimensioned Brandenburg City Canal, which diverges upstream of the Vorstadtschleuse Brandenburg and passes through the city centre, before descending through the Stadtschleuse Brandenburg lock. This traffic then follows the Brandenburger Niederhavel downstream into the Breitlingsee before rejoining the main route in the Plauer See.

For this feasibility study, silver/superconductor jelly-roll samples with a superconductor composition of Bi1.8Pb0.4Sr 2Ca2Cu3Ox (2223), were fabricated via a thick-film processing technique. It was found that the densification and alignment of 2223 grains along the Ag layers was crucial to achieving high critical current densities (Jc). The effects of cyclic mechanical working and heat treatment were investigated to develop a scheme to maximize Jc. The highest zero-field J0 value of 2650 A cm -2 (Ic=43 A) was obtained in a jelly roll heat treated at 815 degrees C, where the majority of the mechanical deformation was performed prior to the first heat treatment. Magnetic-field-dependence measurements made in a 50 G field showed a 23% reduction in Jc when the field was applied parallel to the current flow, and a 30% reduction when the field was applied perpendicular to the current flow. This was superior to the best comparable powder-in-tube samples.

The package "scala" has a number of classes named Product, Product1, Product2, and so on, up to Product22.
The descriptions of these classes are surely precise. For example:
Product4 is a cartesian product of 4 components
Precise, yes. Communicative? Not so much. I expect that this is the perfect wording for someone who already understands the sense of "cartesian product" being used here. For someone who doesn't, it sounds a bit circular. "Oh yes, well of course Product4 is the mumble product of 4 mumble-mumbles."
Please help me understand the correct functional-language viewpoint. What is the sense of "cartesian product" being used here? What do the Product classes' "projection" members indicate?

"The set of all possible pairs of elements whose components are members of two sets."
"Specifically, the Cartesian product of two sets X (for example the points on an x-axis) and Y (for example the points on a y-axis), denoted X × Y, is the set of all possible ordered pairs whose first component is a member of X and whose second component is a member of Y (e.g. the whole of the x-y plane)"
Perhaps better understanding can be gained by knowing who derives from it:
Direct Known Subclasses: Tuple4
Or by, knowing it "extends Product", know what other classes can make use of it, by virtue of extending Product itself. I won't quote that here, though, because it's rather long.
Anyway, if you have types A, B, C and D, then Product4[A,B,C,D] is a class whose instances are all possible elements of the cartesian product of A, B, C and D. Literally.
Except, of course, that Product4 is a Trait, not a class. It just provides a few useful methods for classes that are cartesian products of four different sets.

_USER_ Go here, click "known subclasses", have fun. – Daniel C. Sobral Dec 12 '11 at 22:28
Everyone else has gone for the maths so I'll go for the silly answer just in case! You have a simple car which has a gearbox, a steering wheel, an accelerator and a number of passengers. These can each vary: which gear are you in, which way are you steering, is your foot "on the floor" etc. The gearbox, steering, accelerator etc are therefore variables and each has its own set of possible values.
The cartesian product of each of these sets is basically all possible states that your car can be in. So a few possible values are:
(gear, steer, accel, pssngers)
(1st, left, foot down, none)
(neutral, straight, off, the kids)
the size of the cartesian product is of course the product (multiplication) of the possibilities of each set. hence if you car has 5 gears (+ reverse + neutral), steering is left/straight/right, accelerator is on/off and up to 4 passengers, then there are 7 x 3 x 2 x 4 or 168 possible states.
This last fact is the reason that the cartesian product (named after Rene Descartes by the way) has the multiplication symbol x

Personally I find the maths explanation a lot simpler! – oxbow_lakes Aug 19 '09 at 22:14
From this thread:
From mathematics, a Cartesian Product of two sets A, B is denoted as AxB and its elements are (a, b), where a in A and b in B.
For three sets, the elements of the (Cartesian) product are (a, b, c) and so on...
So, you have tuples of elements, and indeed you can see in the Scala library that all the tuples (like Tuple1) inherit the respective product trait (like Product1).
Think of product as the abstraction and the respective tuple a concrete representation.
The projection allows to get the instance of the 'n' class referenced by the Product.

A cartesian product is a product of sets. Given sets A and B, A x B ("A cross B") is the set of all tuples (x, y) such that x is in A and y is in B. A cartesian product may be analogously defined on types: given types A and B, A x B is the type of tuples (x, y) where x is of type A and y is of type B.
So Product4 is the type of tuples (w, x, y, z), where w, x, y, z are components.

SQL Server Torn Page Detection
_URL_
About SQL Server Checksum Page Verification
"when torn page detection is specified, a specific 2-bit pattern is saved and stored on the page header for each of the sixteen 512 byte sectors. This allows SQL Server to detect when a page was not successfully written to disk, but does not check for the correctness of the data stored on the 512 byte sectors."

Torn page detection
Disk drive manufacturers generally limit data transfer guarantees to sector boundaries of 512 bytes" !!
_URL_
"One of the most common problems is when a power failure occurs and a disk drive is in the middle of writing out a database page. If the drive cannot complete the write before it runs out of power (or write operations are cached and there isn't enough battery backup to flush the drive's cache) the result could be an incomplete page image on the disk. This can happen because an 8KB database page is actually comprised of 16 contiguous 512-byte disk sectors. An incomplete write could have written some of the sectors from the new page but leave some of the sectors from the previous page image. This situation is called a torn page. "

This paper proposes a scalable design for next-generation optical cross-connects (OXCs). We present a novel strategy for dimensioning the switching capability as a long term planning. Switching fabrics in OXCs have to be expanded according to traffic growth, which may incur a scalability problem due to the exponentially increasing cost in manufacturing and maintenance. The proposed scheme expands the switching capacity of OXCs with wavebandand fiber-switching components (or, equivalently, expands the network capacity with wavebandand fiber-switching tiers). To minimize the number of extra fibers for wavebandand fiber-switching tiers required to satisfy a given traffic matrix, we formulate the problem of routing and wavelength assignment (RWA) with tunnel allocation (RWAT) into a constraint programming (CP) process. The CP is simplified as two integer linear programming (ILP) processes that are performed sequentially. Experiments are conducted on four examples to compare the throughput and the number of switching points when different switching architectures are adopted under different traffic increase. The benefits of our approach are demonstrated. Finally, we conclude that the proposed optimization scheme can dimension the networks with expandability and scalability to the growing traffic demand.

The Orange Curtain is a term that refers to the border between Orange County and Los Angeles County in the U.S. state of California. It is a sometimes derogatory, sometimes lighthearted term, that is used to describe Orange County's more conservative and suburban population as compared to the more liberal and urban population of Los Angeles. The Orange Curtain is a word play on the infamous Iron Curtain which separated communist and capitalist Europe.
According to Colleen Cotter, "Because [Orange County] has a reputation for political conservatism, people from Northern California especially worry about what happens 'Behind the Orange Curtain'."
Karin Aguilar-San Juan describes the Orange Curtain as being between 1890 and 1950, as "the region's controlling elite also embraced a John Birch-style ideology of white supremacy and small government.
The song "Orange County Girl" by Gwen Stefani uses this term, stating "I guess behind the orange curtain it's not so bad."

The user interface for RheocalcT presents an enhanced range of choices for test method creation and data gathering/analysis. Loop functions allow performance of repetitive tasks on test samples that require viscosity measurement at multiple rotational speeds, different temperature set points, and discreet time intervals. Viscosity data averaging is now possible for individual tasks within a test step or over multiple steps in the total test program.
RheocalcT collects data from the instrument and allows it to be saved, viewed, printed, plotted and analyzed. QC limits for acceptable viscosity values can be displayed directly on the data graph so that pass/fail decisions can be made on visual inspection. Advanced data analysis to assess yield stress and pseudo plastic index can be performed with a choice of math models: Bingham, Casson, NCA/CMA Casson, Power Law, IPC Paste, and Herschel-Bulkley.
Data management options include export of data files to Excel or to read-only PDF formats. File extension for data managed within RheocalcT software is .vdt. Data files can be shared with other users who run RheocalcT on their PC so that analyses can be reviewed in group discussions.

This is a variation of a theme I've been exploring lately. I want to visualise the paths taken when sometimes opposing forces of attraction and repulsion act on point bodies. In this case, 4 points are paired up, and filled lines with a gold border are drawn between the members of the pairs. These pairs are attracted to each other and will move closer until they reach a certain threshold, whereupon the attractive force changes to repulsion. The pairs are thus constantly either drawn together, or pushed apart. In addition, hidden, non-moveable points are placed in the virtual world. These points also exert forces on the dynamic points according to the same rules of attraction and repulsion. Each dynamic point is given an initial velocity and over time, their paths are traced out. Although theoretically, given enough time it may settle into a static equilibrium, the complex interplay between the myriad of forces and the discrete time nature of computational simulations means that that time is a long way in coming if at all.
Here are some closeups of the tracks.
