Coupled cells with internal symmetry.1. Wreath products
UNSPECIFIED. (1996) Coupled cells with internal symmetry.1. Wreath products. NONLINEARITY, 9 (2). pp. 559-574. ISSN 0951-7715Full text not available from this repository.
In this paper and its sequel we study arrays of coupled identical cells that possess a 'global' symmetry group g, and in which the cells possess their own 'internal' symmetry group L. We focus on general existence conditions for symmetry-breaking steady-state and Hopf bifurcations. The global and internal symmetries can combine in two quite different ways, depending on how the internal symmetries affect the coupling. Algebraically, the symmetries either combine to give the wreath product L (sic) g of the two groups or the direct product L x g. Here we develop a theory for the wreath product: we analyse the direct product case in the accompanying paper (henceforth referred to as II).
The wreath product case occurs when the coupling is invariant under internal symmetries. The main objective of the paper is to relate the patterns of steady-state and Hopf bifurcation that occur in systems with the combined symmetry group L (sic) g to the corresponding bifurcations in systems with symmetry L or g. This organizes the problem by reducing it to simpler questions whose answers can often be read off from known results.
The basic existence theorem for steady-state bifurcation is the equivariant branching lemma, which states that under appropriate conditions there will be a symmetry-breaking branch of steady states for any isotropy subgroup with a one-dimensional fixed-point subspace, We call such an isotropy subgroup axial. The analogous result for equivariant Hopf bifurcation involves isotropy subgroups with a two-dimensional fixed-point subspace, which we call C-axial because of an analogy involving a natural complex structure. Our main results are classification theorems for axial and C-axial subgroups in wreath products.
We study some typical examples, rings of cells in which the internal symmetry group is O(2) and the global symmetry group is dihedral. As these examples illustrate, one striking consequence of our general results is that systems with wreath product coupling often have states in which some cells are performing nontrivial dynamics, while others remain quiescent. We also discuss the common occurrence of heteroclinic cycles in wreath product systems.

The Portsmouth Gaseous Diffusion Plant is located in south central Ohio, approximately 32 kilometers (20 miles) north of Portsmouth, Ohio, and 112 kilometers (70 miles) south of Columbus, Ohio. The site is situated on a 1,483-hectare (3,708-acre) federal reservation
approximately 6.5 kilometers (4 miles) south of the Village of Piketon. Construction of the Portsmouth Gaseous Diffusion Plant began in late 1952 to expand the Federal Government's gaseous diffusion program already in place at Oak Ridge, Tennessee and Paducah, Kentucky. The facility was built to increase the production of enriched uranium at rates substantially above the other two facilities because highly-enriched uranium was required for use in nuclear submarine reactors, and low-enriched uranium was needed for commercial nuclear power plants. The first process cell went online in September 1954. A gas centrifuge uranium enrichment program was initiated in the early 1980s at Portsmouth. However, full operation was never implemented for the centrifuge process. Since 1991, the plant has produced only low-enriched uranium for use as fuel in commercial nuclear power plants.

What Causes a Laptop to Short Circuit?
What Causes a Laptop to Short Circuit?
What Causes a Laptop to Short Circuit?
Technology is advancing day by day very fastly. Laptops are part of life for everybody either he is a student, teacher, doctor, engineer or writer. Everybody using laptops randomly and roughly. There are 2 to 3 laptops in every home nowadays because it is the need of everybody.
In this article, our editors have explained all the reasons which cause a laptop to short circuit. Along with this, we have added a detailed guide about fixing problems caused by the laptop short circuit.
As it is very important in our life so when its processor shows some problem many of work stuck down due to defect in laptop. People use laptop recklessly and it causes a laptop to short circuit.
First of all, we have to know what is a short circuit?
What is the short circuit?
It can be defined as low resistance of the connections in laptop. Low resistance between the circuit and power supply that are giving it to Electrical power. Due to low resistance high current will be passed and it causes a short circuit.
A short circuit can be an alternating current AC and also can be in direct current DC circuit. The short circuit in the laptop produces a high temperature that damage the whole circuit and battery can explode due to heat. You must always keep your laptop secure from a short circuit.
What Causes a Laptop to Short Circuit?
Any physical damage or any electrical damage can cause a short circuit in laptop. A short circuit will consume all the power and it causes your laptop not to turn on.
 If your adapter is working when you put up on the wall and then stop working when you connect it into your laptop then it means short circuit takes place in laptop. When two wires in the circuit that should not be connected, they get connected short circuit takes place.
Causes of Short Circuit in Laptops and how can we fix it
There are many causes of a short circuit in a laptop:
Spilling of liquid:
The electrical circuit of the laptop can be damaged by the spilling of water or liquid on it. A liquid can cause these types of damage:
 - A short circuit caused by wet liquid (problem removes after liquid cleaned and dried)
 - A short circuit caused by dried liquid residue
 - Corrosion (especially with Coke or Pepsi)
 - Electronic components damaged by above short circuits
During using a laptop if you spill water or any liquid on a laptop, it can cause a short circuit. It is very common that we keep eating and drinking during work on the laptop. So it can cause a short circuit.
Fix it:
if you spill liquid while using your laptop then these tips can give you fighting chance to salvage parts of your laptop.
 - Turn off your laptop immediately.
 - Unplug the laptop from its power cord. Press the power button for the 4 seconds that it turns off the power of a laptop or shut down the laptop.
 Remove the battery of the laptop. Disconnect the battery from the laptop.
 Clean the laptop with a highly absorbent cloth that it cleans visible liquid on a laptop so that it could not cause a short circuit.
Dry it with dryer and wait for 3 hours then you can use a laptop easily.
Issues in Laptop Power supply can cause a short circuit
Check power supply by plugging it into the wall of outlet to check the LED of the power supply lights up. The power adapter should not plug into the laptop, only the wall of the strip outlet.
Laptop adapters have LED light, which allows users to identify either current is passing from the adapter or not.
If the LED light is not turning on, check it in another outlet. If you still see no light, then the surge protector in the cable is burnt and the cable needs replacement.
Fix it:
 this can be resolved by buying a new adapter for the charging of laptop otherwise it would because of short circuit. Because burnt cable could not provide a sufficient amount of current to the laptop.
High Voltage:
Due to damage to the cable or power supply or any other cause of high voltage. Any problem with electricity that increases the voltage input can cause a short circuit of laptop.
High voltage effects on the circuit of the laptop that decrease the resistance of current and large amount of current pass from the circuit and short circuits happens. High voltage can also cause errors in the laptop processor.
Fix it:
Test the output voltages. Put a positive pin inside the cable power connector that inserts into a laptop. Put the negative pin on the outside of a cable connector. Check the digital display to see the reading.
Test that the output is correct by reading the recommended output levels. Replace the power cable if the voltage output has a large variability.
Low Voltage:
Due to an error in power supply, not proper current can pass from the power supply and it causes a short circuit in the laptop.
A laptop requires a sufficient amount of current for charging so when not proper current converts into the socket of power, it causes a short circuit to the laptop.
Fix it:
By replacing a power supply, one can secure its laptop from short circuit.
Hardware devices cause short circuit:
A short circuit can also be caused by any defective hardware devices like floppy, USB, DVD, CVD or CD player hardware. Because this hardware might contain any virus that affects the circuit and short circuit can take place.
Fix it:
Use millimeter or an ohmmeter for testing of short circuits in the laptop. Put the positive pin inside of the power connector of the laptop. Put a negative pin on the outer metal part of the connector. Check the millimeter digital display. If reading is less than 3 ohms, it is an indication of a short circuit.
Remove devices like CD, DVD, and ROM, battery, Floppy or any other connected device to see if it is the cause of the short circuit.
Turn on the laptop without these devices to see either laptop starts or not.
Dust and improper placing:
Laptops should be placed on a neat and clean surface. A person should use a protector for its screen and its body that it can be protected from the dust. Because dust particle form clog into the laptop which can affect the circuit and short circuit can take place. You should always maintain a clean laptop.
The irregular placing of laptop or placing a weight on the laptop can cause short circuit and damage of the laptop. A laptop should place on the plain surface to protecting from the damage.
Fix it:
This problem can be solved by drying out the dust from the circuit by the dryer. Blow dry moves out the dust particles from the circuit.
How to prevent a laptop to short circuit?
there is some safety precaution to prevent from the short circuit:
 - While using laptop avoid the use of liquid or water near the laptop.
 - Avoid taking the coffee or tea during using a laptop but if you don't work without these things then take them with special care.
 - You can also use motherboard protector that if something is spat on the motherboard it will not cause the short circuit.
 - The power supply should be placed at a safe place that it could not breakdown or damage.
 - A laptop should be placed in its bag and power supply with it.
 - The laptop should be used in room temperature because high temperature can cause a short circuit. You can use a laptop without a battery.
 - Make sure that electricity supply is in range, and then connect the power supply with laptop otherwise short circuit can take place due to insufficient or high voltage.
 - A laptop should be placed out of the reach of kids.
 - Hardware devices should be installed in the laptop after rechecking that they are free from virus, these drives interrupt the circuit and shirt circuit takes place.
 - A laptop should place in a dry and clean surface.
 - Any weight gaining thing should not place on the laptop it damages the laptop and short circuit might be possible.
Final Words about Electrical Short Circuit in a Laptop
As we are talking about the short circuit of a laptop so I am sharing my story of laptop. We all know that load shedding and electrical fluctuations is a common problem from the last few years.
so 6 months ago my laptop was on charging and suddenly load shedding happens and I forget to remove my laptop from charging. Now, when the light comes it comes with high voltage power and it damages many electronics in the area.
Fortunately, only the laptop was on charging other appliances was not switched on, so when checking my laptop its power supply was not working.
High voltage damages my laptop charger by not my laptop because the laptop power supply contains a protector. whenever high voltage or improper voltage passes from it, it acts as a fuse and destroy itself and protect the laptop from the damage. So in this way, my laptop remains safe from a short circuit.

Passion blogging: What is it and how does it improve students' writing skills?

How does passion blogging encourage student productivity? Source: Andrew Neel/ Unsplash
During university, writing assignments enable students to develop their communication and critical thinking skills.
But depending on the course, some students are subject to regular writing assignments more than others. When these regularly revolve around overused or niche topics, students may lose interest and lose out on the benefits of writing.
Passion blogging could be one solution, according to English and journalism teacher Allison Berryhill.
student productivity
How does this method motivate student productivity? Source: Brooke Cagle/ Unsplash
Writing in Edutopia, she explained that passion blogging is founded on what students know and care about.
By encouraging her students to set up an online blogging space, Berryhill's students are free to write about what they're passionate about.
"My students' passion blogs resulted in creative, voice-filled analyses on wide-ranging topics," she wrote.
This included topics such as the 19th Amendment, the best local hiking trails, why Austin Forkner is an amateur Kawasaki legend, a student's cataract surgery, (…) hunger strikes, a grandfather's escape from Iran, and the Best of Iowa competition at the county fair.
By allowing students to write about topics of interest, Berryhill finds learners to be more engaged with the writing assignments and excited to get started on their pieces.
"Our class blogs are intended as a practice space for developing skills, and I grade them accordingly."
Berryhill awards full credit to blogs that show attempts at passion (voice), authority (attribution and care with mechanics), structure (organisation and transitions), and ideas (supported with examples).
Through this frequent low-stakes practice, students are able to learn how to structure arguments, provide evidence and explain their thought process – all of which are skills they can apply when in subjects like literature.
Alternatively, a passion blog may also inspire a writing career.
For instance, SG Budget Babe financial blogger Dawn Cher always had a passion for writing since she was young.
"I never had a target audience, nor did I write to get recognised. In the beginning, it really was just a blog I started for fun and shared on my personal Facebook for my friends to read," says Cher.
But since she started the blog, she has received over four million visitors and has been ranked as a Top 60 Budget Blog by Feedspot.
Cher's story demonstrates where passion and productivity can take writers, while Berryhill's approach shows how passion blogging is enlivening her writing classes.
University lecturers may want to consider implementing it in their classes too – if they haven't already.

Support Local Art
art Buy local culture Support local tourism
From: Backpackers South Africa
Why it's important to support local art
Supporting local talent is a great opportunity for cultures to connect, and for communities to grow together. There are so many reasons why you should support local work, and apart from it driving tourism and rewarding innovative minds for their beautiful talents, art has the ability to share common values and beliefs between different groups of people. This type of communication is important for society.
No matter the place or origin of the piece, what matters is skills used to showcase that beautiful social structure.
 It fuels the economy
In such tight economic conditions, artists struggle to sell their work and individuals struggle to support them because of the cost. With local art, it's affordable and it's easier to support because you're supporting content that resonates with you.
The art is original and different
The beauty of local art is that there are so many African art styles to choose from. Be it landscapes, portraits or wildlife, local artists always offer something original and unique. Most pieces are designed without the latest technologies to assist or speed up the process, therefore these handmade pieces are one-of-a-kind. When you buy something that is carefully crafted and different, it brings a sense of exclusivity into your purchase.
It's affordable for society
When you support and buy from local artists, most of them aren't well-known for their work, which is why it tends to be affordable in the beginning. That piece of art then becomes a long-term investment, because as the artist becomes more recognisable, the piece of art will rise in value.
 It creates a sense of culture
Art is a common denominator in almost every country's history. Creativity is a beautiful experience that brings people and communities together, regardless of race, gender, age or religion. Take African art for example, artists always express their feelings towards a specific topic which resonates with many people. That feeling then brings cultures together to celebrate our heritage.
It drives tourism
As mentioned, art is a universal language that people appreciate and respect. Over the years, people have lost hope in African creativity, but slowly it's becoming a refreshed tourist attraction for many travelling to S.A
It inspires young minds
Younger generations are delving into creative careers where they've started using their talents to earn money. In order to keep the trend going, our existing communities need to support local art to show children just how important and special it is.
Final words
Beyond the creative benefits that art has on society, art has a measurable impact on our economy, health and well-being, society and education. It allows people the opportunity to communicate across barriers of language and culture, where words cannot be used to express the same thoughts.

What is INP? 5 Tips to Optimize Interaction to Next Paint for a Better User Experience
Interaction to Next Paint (INP) is a new performance metric for Core Web Vitals, launched by Google in March 2024. In the coming days, INP will replace the First Input Delay (FID). Let's understand, what is this INP, and why is it important.
inp
Here, we will discuss Interaction to Next Paint in detail and learn how to measure it for your website. We will dive into the tips to optimize INP for a better user experience (UX) as well as search Engine Optimization (SEO) rankings.
What is INP?
Interaction to Next Paint (INP) is a new Core Web Vital metric that focuses on measuring user interface responsiveness. In simple words, it measures how quickly a web page responds to a user interaction such as key presses or clicks.
INP Module
The goal of Interaction to Next Paint is to measure the length of time from when a user initiates an interaction to the next frame print, so the website can improve it, if needed. An interaction can be controlled by CSS stylesheets and JavaScript files.
The interactions involved in Interaction to Next Paint's calculations are:
 - Clicking a mouse
 - Pressing a key on a keyboard
 - Tapping a touchscreen device
The Factors that Affect INP
Interaction to Next Paint measures the time taken between your user input and the next updates. Several factors contribute to the interaction latency.
 1. User interaction
The measurement begins from the moment when a user interacts with a web page. As mentioned before, this interaction could be keypress, click, etc.
For example, when you visit RabbitLoader.com, put any website's URL and click the Analyze button.
 1. Input Delay
Input delay refers to the time taken before the web page starts processing an interaction. During this process, the web browser might be busy with some other tasks, which can delay the processing of a user's input.
Factors that Affect INP
 1. Processing Time
After receiving the input, the next phase is the processing time. It refers to the time required for the browser to analyze and interpret the request or insert data, perform any calculations, and generate the response or output.
 1. Presentation Delay
After generating the output or response, it takes some time to render the response to the user. It includes tasks such as executing any CSS changes, recalculating the page layout, and so on.
The total time taken by these 4 steps, would be known as Interaction to Next Paint.
The difference between INP and FID
Both the Interaction to Next Paint and First Input Delay (FID) are key performance metrics to measure user interaction and engagement on a webpage. However, there is a difference between these two performance metrics.
fid vs inp
While Interaction to Next Paint considers all user in-put events, the FID metric measures only the initial delay between a user's first interaction with a website
How Do We Measure INP?
Now you have a brief idea about Interaction to Next Paint. There are several tools available to check INP. Here we are explaining the process to check INP for your website.
Check INP issues using Chrome DevTools
Let's check the INP metric by using Chrome DevTools. Here we are mentioning the steps that you need to follow.
 - Step 1: Right-click on the web page and select Inspect or press F12.
inspect website
 - Step 2: Click on the Performance tab.
Click network tab performance
 - Step 3: Click the record button or press Ctrl+E, perform some interactions on the page, and then stop the recording.
Click ctrl+e
 - Step 4: After loading the profile, Click on Main Thread.

What is Considered a Good INP Score?
Similar to the other Core Web Vitals metrics, the website's INP score can be in one of the three thresholds. According to Google, a good Interaction to Next Paint value should be less than 200 milliseconds.
An INP of less than 200 ms means the web page has good responsiveness.
 An Interaction to Next Paint between 200 ms and 500 ms indicates the web page's responsiveness needs to be improved.
 An INP above 500 ms is considered that the web page has poor Interaction to Next Paint or responsiveness.
 5 Tips to Improve INP
 Optimizing Interaction to Next Paint is the key to enhancing a website's responsiveness as well as user experience (UX). Let's see the 5 easy ways, you can improve the INP of your website.
 Minimize CPU Processing on the Web Page to Improve INP
 To minimize the CPU process on the web page, you can follow these strategies.
 - Reduce JavaScript Execution: The execution of JavaScript files can significantly contribute to CPU usage.
 The most common way to minimize CPU processing is to use Vanilla Javascript. Using Vanilla JS means using pure JavaScript without using additional libraries like JQuery. Because every library has its in-build code, it will increase file size as well as CPU processing.
 /*This is demo of JavaScript syntax
 *Below you can change some editor options */
 function hello(arg) {
 var string= arg-join('');
 if (/^H\w{2}.o\s*$/i.test(string)) {
 return string;
 }

 }
 var result=hello(['H','e','l','l','o'])
 console.log(result);
 - Efficient Event Handling: Handling events efficiently is important for reducing CPU usage. To improve your INP, You can use event delegation on the parent elements rather than using event listeners for the multiple-child elements.
 - Cache Data: You need to implement a caching mechanism to temporarily store static resources ( HTML, CSS, JavaScript, Images). It will help to increase your website's pageSpeed.
 You can use the RabbitLoader plugin in wordPress to implement the cache functionality. If you need to implement this on other platforms such as Laravel, PHP, or even Shopify you can still use RabbitLoader, check out our platform page for more information.
 Reduce Input Delay to Improve INP
 When a user interacts with a web page, the first phase of that interaction is input delay. It happens due to activity occurring on the main thread, timer function, fetch handling, and others.
 inp
 To reduce input delay first you need to optimize event callbacks by following the below strategies.
 - Yield to the main thread: The best advice for optimizing callback events is to do as little work as possible. The next thing you can try is to break up a long task into separate tasks.
 setTimeout() method is the only way to break up the whole task. The commonly used syntax is setTimeout(function, milliseconds).
 For example,if you want to display the time every 10 seconds. For that first, you need to define a function to show the current time. Then by using the setTimeout() method, you need to break the function. So that it can execute every 10 seconds.
 The code:
 function showTime() {

 // return new date and time

 let dateTime= new Date();

 // returns the current local time

 let time = dateTime.toLocaleTimeString();

 console.log(time)

 // display the time after 10 seconds

 setTimeout(showTime, 10000);

 }

 // calling the function

 showTime();
 - Yield to allow rendering work to occur quicker: Yielding can help prioritize the rendering work to occur quicker by deferring the other tasks.
 Let us understand with a real-time example. You have a website with a rich text editor. Four things can happen on your website. 1) update the text box, 2) Update the UI part to display the word count. 3) execute the logic to check the spelling and finally, 4) save the changes.
 Here is the code for the above process.
 textBox.addEventListener

 ('input', (inputEvent) =>{

 'Marimo' is a Japanese word which means seaweed ball. Although it's called a moss, it's actually an algae which takes up a spherical form when it grows. From the center of the algae to the outermost layer, it is a solid algae. There is no kernel or a core of any sort which allow the algae to latch on. It grows at a tremendously slow speed; however, if ideal conditions are provided it can potentially grow between 8 to 12 inches a year! Marimo Moss Balls are one of the most popular kinds of moss among plant enthusiasts and fun...

Abstract
In this paper, we experimentally compare the efficiency of various database engines for the purposes of querying the Wikidata knowledge-base, which can be conceptualised as a directed edge-labelled graph where edges can be annotated with meta-information called quali- fiers. We take two popular SPARQL databases (Virtuoso, Blazegraph), a popular relational database (PostgreSQL), and a popular graph database (Neo4J) for comparison and discuss various options as to how Wikidata can be represented in the models of each engine. We design a set of experiments to test the relative query performance of these representa- tions in the context of their respective engines. We first execute a large set of atomic lookups to establish a baseline performance for each test setting, and subsequently perform experiments on instances of more com- plex graph patterns based on real-world examples. We conclude with a summary of the strengths and limitations of the engines observed.

Self-handicapping is a maladaptive behavior which undermines students' achievements, but the antecedents of self-handicapping are not well studied in physical education. The aim was to examine the relations of implicit theory of abilities and self-handicapping in physical education. 264 college students, whose mean age was 20.3 yr. (SD= 1.7), completed the Conceptions of the Nature of Athletic Ability Questionnaire-2 and Self-handicapping Scale for Sport. Analysis indicated entity beliefs positively predicted reduced effort and making excuses. Also, incremental beliefs negatively predicted reduced effort. Results are discussed in terms of implicit theory of ability and self-handicapping. Directions for research and implications are stated.

Installation of Water Level Gauge Stations
- Purpose: To grasp water level fluctuation of the wetland. The water level is very important and essential baseline information to manage all of conservation activities.
- Outcome: 4 stations were installed and started to monitor in 1.Nahang Roga, 2.Sorkhankol, 3.Sosar Roga and 4.Abkenar in October 2015. Remote monitoring can be available by mobile network.
- Future Plan: Monitoring should always be conducted to manage the wetland ecosystem.
- Topic: According to the result of water level monitoring, the water level at Sorkhankol Wildlife Refuge is almost the same as that in the Caspian Sea during dry season. It rises in conjunction with increasing rainfall and the water level at Sorkhankol keeps about 10 cm higher than in the Caspian Sea. Further accurate trend of water flow among Sorkhankol , West lagoon and Caspian Sea will be clarified after precise leveling which is now ongoing.

Anubis, Companion to Osiris (Cont)
By Lee McGiffen
Immortal and Mortal Stars
Let us be more specific about the distinction between these two types of stars. The Pyramid Texts distinguish between the circumpolar stars which are considered immortal or imperishable, because they do not descend below the horizon, and the non-polar stars which are considered mortal, because they set and enter the Underworld, the Land of the Dead.
The cycle of the mortal stars is a metaphor of the reincarnation of the soul. But as in Buddhism, the ultimate aim is to escape the cycle of incarnation and to become immortal like the never-setting stars.
The relationship between the immortal and the mortal stars is reflected in the relationship between Anubis and Osiris. Anubis is immortal because he represents Ursa Minor. Osiris is mortal because he represents Orion's Belt. Orion's Belt may have taken on even more significance in this context. Knowing of the precession of the pole, the priests would have known that Orion's Belt takes up a position on the celestial equator, precisely at that era when Polaris in the constellation of Anubis took up its position at the celestial pole.
The doctrine of the mortal and immortal twins is widespread. For example, it occurs in the Zoroastrian tradition as the pair Yima and Mithras. In Greek mythology, it is Castor and Pollux, who are constellated in the sky as the two brightest stars in Gemini. The myth of Castor and Pollux does not belong to Gemini. The myth of the mortal and immortal twins is about circumpolar and non-polar stars. The myth of Castor and Pollux shows how an ancient Egyptian myth of duality in the sky can be constellated into a single constellation in a seemingly unrelated part of the sky.

Naval Historian Describes U.S. 7th Fleet's Impact in Asia
By John Valceanu
American Forces Press Service
WASHINGTON, Sept. 28, 2012 The U.S. 7th Fleet has played a key role in American foreign policy and has had a major positive impact in Asia since being stood up during World War II, a historian told an audience of military service members and Defense Department civilian employees at the Pentagon.
Edward J. Marolda, author of "Ready Seapower: A History of the U.S. Seventh Fleet," outlined the contributions made by the fleet over the past half century. Marolda teaches at Georgetown University and is a former senior historian at the U.S. Naval History and Heritage command. He has authored, coauthored or edited 12 books on U.S. naval history.
"The U.S. 7th Fleet has had a dramatic and lasting influence promoting and protecting U.S. interests in the Far East," Marolda said. "It's been a major factor in bringing stability to the region, enabling countries relying on us to prosper economically. By the same token, it's helped our friends in the region to develop democratic governing systems and universal human rights ideas."
The historian described the fleet's trial by fire during its early years in World War II, mainly under the leadership of Vice Adm. Thomas C. Kinkaid. Marolda touched on Kinkaid's sometimes contentious relationship with Army Gen. Douglas MacArthur, who was the higher-level commander in the South West Pacific Area.
"The most stellar accomplishment of the fleet" in World War II was the Battle of Leyte Gulf, Marolda said, calling it "a key turning point" in the war. The battle took place from Oct. 20 to Dec. 31, 1944, and launched the Allied campaign to recapture the Philippine Archipelago and liberate it from the Japanese.
After World War II, the 7th Fleet became a permanent forward-deployed force based in Asia. Marolda said that presence became an important political presence in the Pacific region, helping to deter aggression among states.
"When all else is quiet, and there are no wars going on, deterrence is still a big part of the mission," Marolda said. As an example, he cited the China-Taiwan crises of 1954-55, 1958, 1963 and _PHONE_, in which China threatened military action against Taiwan.
"Our naval presence really did stop them from taking any action," Marolda said. "It gave them pause and cause for caution."
Marolda quoted Mao Zedong, who led the People's Republic of China from 1949 to 1976, as saying, "the 7th is the biggest fleet, and it surrounds us."
In addition to deterrence of aggression, Marolda said the 7th Fleet also helped maintain the freedom of the seas for trade and shipping by suppressing pirates. In doing so, it enabled economic prosperity to flourish.
Allied nations like Japan, South Korea, the Philippines, Australia and New Zealand all benefited from the 7th Fleet's efforts, he said, as did even the People's Republic of China, which took advantage of reduced piracy and free seas to expand its international trading activities. The results have been a much more stable region and a proliferation of more democratic governments.
"It has been one of the primary instruments of U.S. foreign policy in Asia," Marolda said. "Behind the shield of the U.S. Navy, economic and political prosperity were able to occur in the region. By protecting our maritime allies, the fleet was able to counter both Marxist-Leninist and radical Islamist movements."
Along with deterrence, Marolda said the 7th Fleet used "soft power" to show nations in the region that the U.S. wanted to do the right things and shared in their values. Examples include refugee evacuations, disaster relief and humanitarian operations.
The fleet helped in various ways over the years, including working with North Vietnamese refugees escaping by boat during the Vietnam War and providing disaster relief during the 1991 volcanic eruption of Mount Pinatubo in the Philippines and the 2004 earthquake and tsunami in the Indian Ocean, Marolda said.
Though these are missions for the fleet, the most important reason for its existence is the ability to fight wars, Marolda said, and the 7th is the only U.S. fleet to have been involved in every major conflict since World War II. During the Korean and Vietnam wars, the fleet's ability to control the sea was critical.
"Both in Korea and Vietnam, naval power was absolutely vital to whatever success we had," Marolda said, noting that the fleet was able to deny the use of the seas to adversaries, thereby preventing the movement of supplies and personnel.
"We could not have fought those wars the way we did without being able to control the seas," he said.
Marolda's book is available for download from the U.S. Navy's Naval History and Heritage Command site, and it may be purchased in book form through the U.S. Government Printing Office. The presentation was sponsored by the Historical Office of the Office of the Secretary of Defense as part of its History Speaker Series.

TenMarks teaches you how to use intermediate concepts of proportions to solve problems in indirect measurement.
Read the full transcript »
Learn Intermediate Concepts of Indirect Measurement In this lesson, let's learn about indirect measurements and how to measure things using properties of similarity. The problem states that a tree, as we can see in the diagram, casts a shadow that is 48 feet long. So we've done is drawn the shadow here at 48 feet long and that's the point PQ. A man, whose height is five feet, and that's the man here, I've tried to draw a diagram that says the man whose height is five feet which is illustrated by TS, casts a shadow that is eight feet long. How tall is the tree? This is what we need to determine. That's H. So what are we given? We are given two triangles, right. The triangle first one is, TPS. The second triangle is RPQ. All I did was just label them, okay. Since we got two triangles out of it, we just label them triangle TPS and triangle RPQ. Notice that I was careful to make sure that the angles were the same for the small and the big triangle. So P which is the angle is common between the two in the middle. Since these two triangles are similar, the ratio of their corresponding sides is the same, ratio of corresponding sides are equal. What does that mean? Well let's look at the corresponding sides for both triangles. There is one side that is the big one which is RP. The corresponding side to that in the smaller triangle is TP. So the ratios of this side on the big triangle and side on the little triangle should be the same as these two sides which is PQ on the big triangle and PS on the small triangle, which should be equal to the big height which is PQ or RQ, and the small height which is TS. Now let's substitute what we already know. What are we given? RP, are we given that? RP is not given. TP is not given. So this is useless. Let's look at PQ, P and Q, that's given as 48 feet. PS is given as eight feet equals RQ is what we need to determine so this is the height H and TS is the smaller triangle, and that we're given as five feet. So we've got a ratio that's equivalent to ratios that are equivalent. So the cross products must be equal. So let's look at the cross products, 48 × 5 = 8 × H. All units are in feet. So 48 × 5 = 8 × H, they're cross products which means 48 × 5 is 240 = 8 × H. Let's divide both sides by eight so that I can isolate H on one side. 240 by 8 is 30, 240 ÷ 8 = 30, 8 ÷ 8 = 1 or 8 = 30, since everything is in feet, the height of the tree, since everything is in feet, the height of the tree is 30 feet. That's what we were looking for. The way we got to it is we just look at this triangle and the big triangle, they were similar. That the triangles are similar than the ratio of their sides are equal. We took these four sides. The ratios give us 48/8 = H/5 which when solved gives us H = 30 or the height brings 30 feet.

1) In modern usage the PECL terminators would be tiny resistor networks.
1a) If the PECL signals are fairly static slow data these may not have to be terminated on a short on-board run. But that leads to the question, why did you convert them to PECL in the first place if they are slow unclocked data?
1b) If the PECL signals are clocks or latch enables etc. you probably want to terminate them.
1c) By Thevenin's Theorem most usual way to terminate PECL will end up being like figure 4 in _URL_
2) One terminator at far end. But it is unusual (see my note below 4) to fan out PECL. If necessary to split a signal multiple ways there are fanout buffers e.g. SY100EP11U, but this would be an unusual use of PECL.
3) Wrong. But note by Thevenin's theorem, a 50 ohm resistor to Vcc-2V, can be replaced by two resistors one to ground and one to Vcc. See 1c above.
Overall note: Today you are most likely to see PECL or LVDS used on board-to-board or assembly-to-assembly interconnect cables. It'll be translated to whatever's used on the board right at the terminator.

During the past two decades, many books, governmental reports and regu- lations on safety measures against chemieals, fire, microbiological and radioactive hazards in laboratories have been published from various coun- tries. These topics have also been briefly discussed in books on laboratory planning and management. The application ofvarious scientific instruments based on different ionizing and non-ionizing radiations have brought new safety problems to the laboratory workers of today, irrespective of their scientific disciplines, be they medicine, natural or life sciences. However, no comprehensive laboratory handbook dealing with aIl these hazards, some of which are recently introduced, had so far been available in a single volume. Therefore, it was thought worthwhile to publish this Handbook on safety and health measures for laboratories, with contributions from several experts on these subjects. As this second edition of the Handbook, like the first edition, is a multiauthor volume, some duplication in conte nt among chapters is unavoidable in order to maintain the context of a chapter as weIl as make each chapter complete. An attempt has also been made to maintain the central theme, which is how to work in a laboratory with maximum possible environmental safety.
From reviews of the first edition:
'... will surely become the standard reference for laboratory directors in all disciplines.'
Occupational Safety and Health
'... aimed at anyone working in a laboratory of any scientific discipline, scientists (basic and medical) and laboratory safety officers.'
Trends in Biochemical Science
'An excellent reference book which should be on the shelf of anyone with responsibility for laboratory health and safety measures.'

Acoustic tests on new Glonass-K satellite completed
MOSCOW, August 4 (RIA Novosti) - Acoustic tests on a new generation Glonass-K navigation satellite have been completed at a plant in southern Russia.
"These types of experimental tests were carried out to confirm the resilience of the Glonass-K satellite to the acoustic pressure which will be applied on it when it is orbited," a statement by the plant said. "The tests were successful."
The Glonass-K, a new generation satellite navigation system, is set for launch later this year.
The satellite is operable for 10 years.
Glonass - the Global Navigation Satellite System - is the Russian equivalent of the U.S. Global Positioning System, or GPS, and is designed for both military and civilian use. Both systems allow users to determine their positions to within a few meters.
Russia currently has a total of 22 Glonass-M satellites in orbit, but only 16 of them are operational. The system requires 18 operational satellites for continuous navigation services covering the entire territory of Russia and at least 24 satellites to provide navigation services worldwide.

Take the 2-minute tour ×
In my app I have the following structure:
Activity A calls activity B, and finishes, removing itself from the stack; Activity B receives an intent from activity A that specifies some action to perform, when these actions are performed, the user will see a message indicating it (still in activity B).If the user presses the home button the app will go to background, calling "onPause" and then "onStop". All works as expected.
The problem is that if the user leaves the app in background for a few hours, and tries to open the app again (after a few hours) the onCreate method in activity B will be called with the exact same intent as it received some hours ago from activity A.
(if the user goes back to the app a few minutes after, he will see activity B just like when he left)
What I wanted was that in this case my app would open activity A and not activity B or, activity B but with the message that was on screen when user left.
Looking at the activity life cycle it seems that the app is killing by the OS, all of this makes sense, what I really don't understand is why activity B opens with onCreate method and the same intent as before.

Use onSaveInstanceState() to record the state of ActivityB. Android will call this before it kills the process. When the user returns to the application, it will recreate the process and then recreate whatever activity was on the top of the activity stack (in your case, ActivityB). When it does that, it will pass the saved instance state to the activity as a parameter in the onCreate() call. You should be able to put something in there so that your ActivityB can tell that it is being recreated after a process kill/restart. In that case, ActivityB could just show the user the message again (which it would have to save in the onSaveInstanceState() method) or it could just redirect the user back to ActivityA so that he can start all over again.

thanks this was the solution i implemented and it worked just fine. – paulo Nov 26 '12 at 20:05
This is the expected behaviour described in the Activity lifecycle.
When an activity is started it always receives an Intent object. The intent that was used to start your activity B was preserved by the OS when your ativity was killed, and resend when the activity was returned to "live".
It's up tu your activity preserve the status and restore it as needed. Based on your problem description I would suggest to use onStop() so save to SharedPreferences the activity status and message, and onResume() to read it back. In onDestroy() you should clear the preferences to ensure a new clean cycle start.
share|improve this answer
I ran into same problem, I DO NOT know if its the way or its right to do so, but i just changed the Intent Extra when needed.
intent.putExtra(SEARCH_EXTRA, false);
So your activity does not perform the operation, since it didn't receive what it wants.

This is off topic and not understandable. – Ixx Nov 23 '12 at 22:06

Telestra uses the DIS gateway file to configure many of the DIS parameters for radios, as well as other networking configuration. This application note discusses using the DIS gateway to set up a variety of networking configurations. For more information about setting radio parameters see Application Note 93: Using the Waveform Mapping File to Set DIS Transmitter PDU Enumerations in Telestra.
In ACE Studio, select the Project and Layout. To add a DIS Gateway file select the "servers" folder in the ACE Studio Project Manager and select the DIS Gateway or add a new DIS gateway by right-clicking on the canvas. Click the "Edit File" button to edit the DIS Gateway file. See the examples below.
Warning!! Do Not click the "Wizard" button. Modifying anything in the DIS Gateway window and selecting "OK" will overwrite everything in the manually edited text file.
The [interfaces] section sets the DIS networking configuration includingport, interface, and IP scheme. The [interfaces] section also allows forflexible control of DIS networking on a per DIS exercise ID basis.Below is a typical example, which sets the DIS version, ethernetinterface, UDP Port, and broadcast address for all DIS traffic.
[interfaces] main_bcast = 10.2.255.255 port = 53124 if = eth0
Here is an enhanced example, where each PDU type is put their ownmulticast address:
[interfaces] signal_mcast = 18.104.22.168 receiver_mcast = 22.214.171.124 main_mcast = 126.96.36.199 entity_mcast = 188.8.131.52 port = 53124 if = eth0
Separate ports may also be used for transmit and receive. If noneare specified the default is 53000:
[interfaces] main_bcast = 10.2.255.255 port = 53124 tx_port = 53001 if = eth0
The [interfaces] section may be enhanced to apply different ruleson a per DIS exercise basis. The example below applies specialrules for a range of exercise IDs from 23 to 35, using a differentinterface, port, and multicast address.
[interfaces:23] end_exercise_range = 35 main_mcast = 184.108.40.206 port = 3334 if = eth2
Each exercise can have its own set of DIS network configsby using multiple [interfaces:##] sections. Multicast groupscan also be created based on adding the exercise ID to the lastoctet. A simple mcast by exercise example:
# Will use 220.127.116.11 thru .30 [interfaces:1] end_exercise_range = 30 main_xmcast = 18.104.22.168 port = 3334 if = eth0
# Will use 22.214.171.124 thru .255 [interfaces:31] end_exercise_range = 255 main_xmcast = 126.96.36.199 port = 3334 if = eth2
Below are two files that can be used as a quick reference on how to configure the DIS gateway.The first file is a "quick glance" DIS gateway, which includes nearly all of the relevant commands in a single, valid DIS gateway file. The second file is an exhaustive, fully commented file with descriptions of what each field does.

Uses and benefits of electric fencing
Animal control is perhaps the most widely recognized reason for power fencing. Not only does power fencing keep domestic animals and livestock contained, it has various other important uses, including:
- Keeping wild animals out
- Separating different groups of animals
- Allowing rationing of crops and pasture
- Fencing animals off from eroding areas, trees, rivers and roads
Power fencing has revolutionized pasture management techniques and better pasture management means better profitability for farmers. Permanent or portable power fences are used to subdivide pasture to ensure even distribution of manure over grazing areas. In this way, pastures are kept fresh, short and palatable which ultimately leads to increased milk and meat production. If you are interested in finding out more about pasture management techniques.
Other key benefits of power fencing:
- Easily constructed and maintained
- Durable, because of low physical contact
- Light weight and easily transported
- Easily modified
- Less animal hide and pelt damage
- Deterrent to trespassers and predators
For convenient, economical animal control, improved pasture management and more profitable farming, a Gallagher Power Fence System is the trusted solution.

Necessity is the mother of invention and there are moves afoot for long-time enemies cotton and wool to join forces.
And that would make sense since wool and cotton believe they both have the same eco-friendly credentials to challenge for better environmental ratings in European markets.
International Wool Textile Organisation secretary general Dalena White recently spoke at the panel for Responsible Fibre Production in Germany, chaired by Cotton Incorporated senior vice president Mark Messura.
Ms White said under the current European ratings systems, products made from wool and cotton are at risk of being rated poorly compared to synthetics.
The proposed rating rules for textiles (designed largely by the European Commission) result in all-natural fibres being rated as less sustainable than synthetic fibres.
- Renewable and biodegradable fibres do not receive any positive scoring
- Natural fibres are fully costed for the environmental impacts of growing the plants that lead to fibre formation (including use of the land, water and energy used, greenhouse gas emissions).
- Petroleum based fibres receive no penalties for being non-renewable and non-biodegradable.
- Microplastic pollution does not carry any negative scoring.
"All natural fibre industries, including plant and animal fibres are at risk of being harmed if the EU PEF labelling scheme proceeds without improvement" said Australian Wool Innovation program manager Angus Ireland.

Animal Species:Soldier Crab
The Soldier Crab lives in sandy estuaries and mangroves, and occurs in massive groups that seem to emerge from nowhere all at the same time.
The Soldier Crab is quite distinctive with its small, round, blue body on long jointed legs with purple stripes. As it marches around feeding, it moulds the sand into numerous pellets, sorting through it for organic matter. There is only one other species of soldier crab common in Sydney. This is the smaller Mictyris platycheles.
Soldier Crabs are found from Northern Queensland, New South Wales, to Wilsons Promontory in Victoria. Also, western Indian Ocean to French Polynesia.
Soldier Crabs live on intertidal mangroves, beaches and estuaries.
Other behaviours and adaptations
It is thought that the spontaneous arrival of Soldier Crabs is triggered by the falling tide. If disturbed, they burrow into the sand with a corkscrew motion, disappearing as quickly as they arrived.

Girls play on a trampoline near a home built into a rock at the Rockland Ranch community outside Moab, Utah, Nov. 2, 2012.
Jim Urquhart, Reuters — The "Rock," as it is referred to by the approximately 100 people living there in about 15 families, was founded about 35 years ago on a sandstone formation near Canyonlands National Park in Utah. Polygamy was a part of the teachings of The Church of Jesus Christ of Latter-day Saints and was brought to Utah by faithful Mormons in the late 1840s. The mainstream Mormon church abandoned the practice in 1890, but an estimated 37,000 Mormon fundamentalists continue the practice today and believe plural marriage brings exaltation in heaven.
EDITOR'S NOTE, Nov. 15: This post was originally headlined "Mormons practice faith from Utah cavern." It has been updated to more specifically reflect the small fundamentalist community depicted in these photographs.

What do you do with an area of woodland that doesn't like trees?
That was the conundrum facing Forestry Commission Wales after trees refused to grow on an area of Bwlch Cefn Llian woodland, just north of Rhayader in mid-Wales.
Attempts some time ago to re-stock about 3.5 hectares with mixed broadleaves and sitka spruce failed due to the wet conditions, so foresters came up with the perfect answer – create a wetland haven for endangered wildlife.
Forestry Commission Wales joined forces with Environment Agency Wales and Radnorshire Wildlife Trust to improve the biodiversity of the forest by blocking overgrown drainage ditches, encouraging surface water to spread across the area.
Wetlands are fast disappearing habitats but provide sanctuaries for rare insects, animals and birds such as dragonflies, otters, warblers, wagtails and snipe.
The woodland area proved the perfect location for a wetland as it could be converted with little work and lay within the River Marteg catchment area, where the Wildlife Trust is already working on several projects.
Nick Whythe, Forestry Commission Wales Local Area Manager, said, "The area was unsuitable for commercial tree planting but, through this partnership, we have been able to increase the environmental and biodiversity value of what would otherwise be an area of unproductive woodland.
"Wetlands and their associated fauna and flora are becoming rarer all the time in rural areas due to agricultural and forestry drainage, so creating this area has been immensely satisfying."
Conversion of the site to a wetland took about a week and involved blocking about 400 metres of drains.
The work will also reduce the risk of flooding in the River Marteg by slowing the flow of rainwater into the river, as well as slowing the release of carbon from the peat in the area by blocking off the air to the surface.
Catrin Grimstead, Biodiversity Officer for Environment Agency Wales, said, "Wetlands are very special. As well as providing habitats for some of our most threatened wildlife, they act as sponges, helping to reduce the impacts of flooding and drought, and promoting healthy environments downstream."
Darylle Hardy, Radnorshire Wildlife Trust Project Officer, said the habitat enhancement work was "an exciting new beginning" for the former wooded area that would not have been possible without this partnership.
She added, "We look forward to seeing more wildlife using the site. Already, snipe have found the newly-wetted hollows but we're expecting to see other wetland birds, more amphibians, dragonflies, signs of otters and maybe even water voles in the future."

Pursuing higher education often takes students beyond the borders of their home country. With its rich tapestry of culture and innovative academic environment, South Korea has emerged as a preferred destination for many. If you want to study in Korea, particularly at a revered institution, the Samsung Global Sungkyun Scholarship is one such beacon of opportunity.
The scholarship specifically targets remarkable freshmen. If you're among those chosen for nomination, prepare yourself, as an interview might be on the horizon. The aftermath of the nomination process? You will receive individual notification post the second qualification announcement.
Two notable scholarship options are available, Option A and Option B.
- Complete tuition coverage for four academic years (including the entrance fee). However, maintaining this scholarship requires diligence. Students must:
- Enroll in a minimum of 12 credits (with the exception of 9 credits in the 7th semester) and maintain a GPA of 3.7 or above without any failing grades. For the first and second semesters, a GPA of 3.5 is acceptable.
- Alternatively, an overall GPA of 3.7 across semesters without failing grades is also accepted.
- A stipend of KRW 570,000 monthly (totaling KRW 3,400,000 per semester) for living expenses.
- Priority in dormitory allocation and complete dormitory fee coverage.
- An invaluable 1:1 monitoring program that connects you with alumni, professors, or experts tailored to your field.
- An exclusive counseling program to further aid your academic journey.
It covers only trituration for four academic years and mirrors the academic requirements of Option A.
It's crucial to note that falling short of these academic requirements can have consequences. Failure to meet the required GPA will result in the forfeiture of the scholarship in the subsequent semester. Two such instances will lead to complete disqualification from the scholarship.
If you're keen on exploring study abroad programs, especially in Korea, this scholarship offers a robust stepping stone. Its stringent requirements echo the commitment to excellence and the holistic educational experience it promises. If learning in Korea inspires you, leap, and let the Samsung Global Sungkyun Scholarship pave your way to academic success.

The active cloud cluster from which Viola developed formed about 600 km to the northwest of Cocos Island on 7 December 1979. It was part of a semi-continuous line of convection extending eastward across Indonesia. A tropical depression had developed by 9 December 1979 and moved slowly to the southwest. Using the Dvorak intensity analysis technique Viola reached tropical cyclone intensity at about 0300 UTC 11 December 1979. The cyclone then began to move westward under the influence of an easterly middle level flow north of the sub-tropical ridge.
Viola attained its maximum intensity late on 16 December 1979 when the central pressure was estimated to be near 930 hPa giving a maximum mean wind speed of about 205 km/h. It maintained this intensity as it crossed into the Mauritius Region early on 18 December 1979.
Viola was renamed Claudette and passed close to Mauritius late on 22 December 1979 causing the loss of six lives and injuring 21 people. It was reported that the sugar cane crop on Mauritius was devastated and that buildings suffered considerable damage.
Severe tropical cyclone Viola was notable for its small size and long lifetime. Satellite pictures showed that nearly all of the intense convective activity was within 200 km of the centre. Including the pre-cyclone and post-cyclone stages the storm lasted about 18 days from 9 December 1979.

Lisa does London
Watch this video, then click on Exercise 1
Same video with Precise Subtitles
Lisa tells us that she and her friend Andrea actually wanted to go to Paris (not London) on their vacation, but their friends in New York told them that the French don't like Americans. This is why we titled this lesson 16b because it follows lesson 16 concerning the French.
Our filming team during this trip to the UK included a French woman, so the interviewer gets a direct French opinion on the matter, with Lisa, in the video.
This is Lisa's first trip outside of the USA. She's from Staten Island, one of the 5 boroughs of New York City, and has a typical New York City accent.
As you will see, she's really funny.
What does Lisa do back home in New York? She works in Andrea's nail shop.
The expression 'Fingernail art' is a way to explain the best work done in decorating mostly female finger nails as we see here.

Pronounced /əʊf/Help with IPA
An oaf is a stupid, boorish, or clumsy man.
There's an intimate connection between oafs and elves. In ancient legend, elves weren't the noble creatures portrayed in Tolkien's stories but powerful and dangerous supernatural beings who were more likely to harm humans than to help them. Their name says so: it comes from an ancient Germanic term for a nightmare, a close relative of the first element of the modern German Albdruck with the same sense. Among other nasty habits, elves were thought to bring humans bad dreams and to steal their children, leaving changelings in their place.
It's from that belief that oaf first appeared in English, in the seventeenth century. Originally an oaf was an elf's child, one that had been left in a poor exchange for a stolen human one. In popular superstition, such children were assumed to be ugly or stupid.
The first forms to appear were ouphe and auf, the former turning up several times in Shakespeare's plays, though he used it to mean an elf or goblin. Auf appears in 1621 in the Anatomy of Melancholy by Robert Burton: "A very monster, an aufe imperfect".
By the end of the seventeenth century it had settled to the modern spelling and oaf had moved to mean "idiot child" or "halfwit", then later took on the senses of a large, clumsy man or boy and a rude and boorish man.

Decision trees, a popular choice for classification, have their limitation in providing good quality probability estimates. Typically, smoothing methods such as Laplace or m-estimate are applied at the decision tree leaves to overcome the systematic bias introduced by the frequency-based estimates. An ensemble of decision trees has also been shown to help in reducing the bias and variance in the leaf estimates, resulting in better calibrated probabilistic predictions. In this work, we evaluate the calibration or quality of these estimates using various loss measures. We also examine the relationship between the quality of such estimates and resulting rank-ordering of test instances. Our results quantify the impact of smoothing in terms of the loss measures, and the coupled relationship with the AUC measure.

Galaxy Diamond Glitter Lamp
- Low stock - 2 items left
- Inventory on the way
About This Product
- Ages 12+ with adult supervision
- Size: 36 cm
- Keep upright
- Turn off regularly
- Some assembly is required
- Light bulb is included
- Voltage: 230-240V, 50Hz
- Wattage: Max 30W
WARNING: The glass lamp surface is hot when in use. For indoor use only. Keep out of reach of children.
The Lava lamp was invented by British accountant Edward Craven-Walker in 1963 after watching a homemade egg timer, which was made from a cocktail shaker filled with liquids, as it was bubbling on a stove top in a pub.
There are two liquids in the lamp that are insoluble together and have similar densities. The heat from the light bulb heats the heavier liquid at the bottom of the lamp. It absorbs the heat, expands and becomes less dense.
This change in density is small but enough for the once heavier liquid to float to the top of the lamp. As the blob of liquid moves away from the lamp it cools. This increases the density and it sinks back to the bottom of the lamp. This motion is repeated over and over again creating the continuous motion of the liquid in the lamp.
The interactions between wax and liquid are not an exact science. Your colouring may differ from the image depicted, and may change throughout use.

text: Closed-loop decoder adaptation (CLDA) is an emerging paradigm for achieving rapid performance improvements in online brain-machine interface (BMI) operation. Designing an effective CLDA algorithm requires making multiple important decisions, including choosing the timescale of adaptation, selecting which decoder parameters to adapt, crafting the corresponding update rules, and designing CLDA parameters. These design choices, combined with the specific settings of CLDA parameters, will directly affect the algorithm's ability to make decoder parameters converge to values that optimize performance. In this article, we present a general framework for the design and analysis of CLDA algorithms and support our results with experimental data of two monkeys performing a BMI task. First, we analyze and compare existing CLDA algorithms to highlight the importance of four critical design elements: the adaptation timescale, selective parameter adaptation, smooth decoder updates, and intuitive CLDA parameters. Second, we introduce mathematical convergence analysis using measures such as mean-squared error and KL divergence as a useful paradigm for evaluating the convergence properties of a prototype CLDA algorithm before experimental testing. By applying these measures to an existing CLDA algorithm, we demonstrate that our convergence analysis is an effective analytical tool that can ultimately inform and improve the design of CLDA algorithms.

Each article is divided into two parts—the head and the body. The
body can be divided into a signature part and a text part. The variable
that says what is to be considered a signature is
gnus-signature-separator. This is normally the standard
'^-- $' as mandated by son-of-RFC 1036. However, many people use
non-standard signature separators, so this variable can also be a list
of regular expressions to be tested, one by one. (Searches are done
from the end of the body towards the beginning.) One likely value is:
(setq gnus-signature-separator '("^-- $" ; The standard "^-- *$" ; A common mangling "^-------*$" ; Many people just use a looong ; line of dashes. Shame! "^ *--------*$" ; Double-shame! "^________*$" ; Underscores are also popular "^========*$")) ; Pervert!
The more permissive you are, the more likely it is that you'll get false positives.
gnus-signature-limit provides a limit to what is considered a
signature when displaying articles.
nil, there is no signature in the buffer.
This variable can also be a list where the elements may be of the types listed above. Here's an example:
(setq gnus-signature-limit '(200.0 "^---*Forwarded article"))
This means that if there are more than 200 lines after the signature separator, or the text after the signature separator is matched by the regular expression '^---*Forwarded article', then it isn't a signature after all.

The temperature class is one of the parameters to consider in order to choose electrical equipment to be installed in places with danger of explosion.
Very often this parameter is ignored or underestimated while it's one of the main features of the safety equipment. An electrical device, addressed to classified areas where there might be danger of explosion due to the presence of gases, vapors, mists or dusts, should be chosen considering that, its maximum surface temperature, must not reach, even in case of failure, the ignition temperature of the hazardous substances present in the atmosphere.
A standard method of classification defines the temperature classes of a gas. This standard, defined by IEC, but also acknowledged by CENELEC, is held in IEC 60079-4 Standard "Method of testing ignition temperatures". According to this method, all gases and vapors are divided into temperature classes. According to these classes, the equipment maximum surface temperature reached is always lower than the ignition temperature.
The Standard defines in detail the maximum values and the necessary safety net for these temperatures.
The standard IEC 31241-2-1 "Electrical apparatus for use in the presence of combustible dust - Part 2: Test methods - Section 1: Methods for Determining the minimum ignition temperatures of dust" defines the ignition temperatures of combustible dusts.
In this case, there're different temperatures depending on whether the dust is in the shape of static layer or in the shape of dynamic clouds.
dl = Layer of dust
dc= Cloud of dust
Often the concept of surface temperature is incorrectly interpreted. Many technicians believe that the maximum surface temperature is the temperature within a device can be used. So, absurdly, are convinced that higher is the temperature and better is the equipment. On the contrary, as we have seen, is exactly the opposite. The best devices are those that, in conditions of normal operation and during a fault, have the lowest possible temperature, which cannot ignite the explosive atmosphere.

Nearly all of Georgia's schools are out for the summer. While the students are gone, it doesn't mean that Georgia's educators have stopped working. I know several of my friends are setting up classrooms for next year and many are continuing their education this summer so they can be fresh and interesting when school starts again in the fall.
On that note, we'd like to tell you about a free webinar on June 7 at 1pm available through Discovery Education featuring Philippe Cousteau to kick-off The Big CleanUP, an exciting summer-long contest involving young people taking action to protect our world's oceans. The webinar is a partnership between EarthEcho, TerraCycle, and One World One Ocean with a simple mission: remove plastic from the waste stream and earn money for your school. Prizes include a school visit from Philippe Cousteau and others, film passes, and more.
During this webinar, you will also explore how plastic affects the oceans, how these issues relate to classroom learning, and how young people can take a lead in protecting our oceans. Speakers include Philippe Cousteau as well as guest speakers from TerraCycle, a national recycling system for previously non-recyclable or hard-to-recycle waste, and One World One Ocean, a multi-year campaign harnessing the power of film, television and new media to restore a healthy ocean.

Series GWL Guided Wave Radar Transmitter
Product Announcement from Dwyer Instruments, Inc.
The Series GWL Guided Wave Radar Transmitter for Liquids is a level transmitter providing continuous level indication of liquids. The sensor can output level indication as a continuous measurement reading through its 4 to 20 mA analog output, or it can alter that information into freely adjustable (NC) switching output signals. State-of-the-art Time Domain Reflectometry technology in this transmitter makes for excellent accuracy and stability. Suppression of disturbance signals allows the GWL to measure precisely even when operating close to interfering structures. This series is available with either a rigid or flexible probe depending on the application installation required, as well as a custom probe length. One of the GWL characteristics is virtually no installation restrictions making it ideal for small tanks, tall and narrow nozzles, and various other types of processing and storage applications. The guided wave radar transmitter for liquids features exceptional performance in liquids with low reflectivity such as oils and hydrocarbons, and factory settings can be configured via HART® Communication protocol.
METHOD OF OPERATION
The GWL senses low-energy, high-frequency electromagnetic impulses, produced by the sensor which are transmitted along the probe immersed in the fluid to be measured. When these impulses hit the surface of the liquid, part of the impulse energy is reflected back up the probe to the senor which then utilizes the time difference between the impulses sent and the impulses reflected to determine the fluid level.

The HALO detector is now in operation, since May 8, 2012.
The announcement from Clarence Virtue:
We are happy to share with you that, just in time for the grand opening of
SNOLAB, the Helium and Lead Observatory for Supernova Neutrinos (HALO) is
up and running. The concept of HALO dates back to 1996 when Cliff Hargrove
proposed the Lead Astronomical Neutrino Detector (LAND) as a long lifetime
supernova detector. In 2004 Charles Duba renamed the nascent detector to
HALO when we decided to use the 3He proportional counters from the SNO
experiment. The design and construction of HALO started in 2007.
The purpose of HALO is to observe the neutrinos from the next galactic
supernova. These particles stream out before the photons do, giving us an
opportunity to alert astronomers through the Supernova Early Warning
System (SNEWS) so that the light signal can be caught in real-time. Just
like we were able to look into the Sun with the SNO detector, HALO and
other supernova detectors, will give us a window into the mechanics of the
Although we still have much work to do to fully calibrate the detector, we
have all of the 128 proportional counters connected to 64 data acquisition
Supernova, we're ready for you!
