Can You Use A Paper Towel As A Coffee Filter Substitute?
This article answers an unusual question: Can you use a paper towel as a coffee filter substitute? We propose some ideas for improving the taste if you're out of options.

Paper towel is the closest coffee filter substitute you can find at home
You lazily walk into the kitchen with disheveled hair and eyes half-open to brew an aromatic pot of Java only to realize that you are out of coffee filters. OMG! What will you do?
This may spark feelings of anxiety and my true condolences are with you. But, you are not alone! Almost every coffee enthusiast or others faces this predicament when there is not enough time to rush to a store to get filters and you also don't want to go to the coffee shop.
So, what's the other alternative? A paper towel, because this is the closest substitute you can get for a filter. Just make sure you do not make it a habit to use paper towels frequently, and you will not have to worry about any health hazards.
Can You Use a Paper Towel As A Coffee Filter?
Yes, you can. When you have run out of coffee filters and you badly need your morning fix, you can try your old college roommate's method for a quick fix. As you put that paper towel in the filter cup, you may wonder if you are doing the right thing.
What about chemicals in the paper towel? Will they leach into your cuppa? Is this method harmful to your health? Let's find out.
Your coffee filter has a lot in common with paper towels. Other than the thickness and ability to absorb, they are few differences between the two. However, if you thought a paper is only made of wood pulp then you are mistaken.
You need to keep a few things in mind when using a paper towel as a substitute filter and I have mentioned them below:
Are The Papers Towels Bleached?
When the thought of using a paper towel in the place of filters crosses the mind, the first thing or concern is chemicals used for bleaching paper towels. Paper bleaching is certainly an issue and it can allow unwanted chemicals to leach into your cup.
However, in most cases, the contaminants are not severe and the health risks are negligible (unless you make it a habit to use paper towels every day).
When you pour hot water over the grounds placed inside the paper towel, water acts as an extracting agent for any industrial chemical used in the manufacturing process. As most paper towels are bleached using chlorine, the chlorinated dioxins present in the product may pose some health risks.

Surprisingly, a study in the '80s revealed that one in every ten thousand cases of cancer among coffee drinkers was due to dioxins leaching from the paper filters. While the chemicals leaching from coffee filters are low, the number of dioxins extracted from paper towels may certainly be harmful to your health in the long run.
While the recent improvements in the paper bleaching industry have reduced this risk to a large extent, some traces of dioxins may still be present in the bleached paper. If you wish to completely eliminate the risk of dioxin intake, switch to natural paper instead!
Are The Paper Towels Recycled?
Well, let's not forget that the paper towels were not designed to be used as a coffee filter. It is meant for wiping, but of course, you may use it as a makeshift paper filter when you badly need coffee and the box is empty. Everyone does. I have done it too.
However, the paper contains contaminants that it gets during the manufacturing process. These contaminants like strengthening agents, fillers, and dyes have rarely gone through toxicity testing. Some papers may even contain phthalates, Bisphenol-A (BPA), and other hormone imitating chemicals.
Food regulators approve these products because they believe that the papers will not come in contact with the food we consume. When the paper is recycled, contaminants also get recycled with the wood pulp, resulting in traces of chemicals in recycled paper towels.
That does not mean that you should not buy recycled paper towels because they have a myriad of environmental benefits. Just that using them for filtering your coffee is not the ideal way to start your mornings.
How To Use A Paper Towel As A Makeshift Coffee Filter？
Running out of coffee filters on a cold winter morning may feel like a big deal. You certainly don't want to go out of the house without something filling your grumpy stomach. This is when paper towels can come to your rescue.
Almost every household has paper towels so when you are in a situation like this, just grab a towel and make a temporary filter out of it. While your coffee may not taste as great, it is certainly better than no coffee at all!
Step 1: To make a temporary coffee filter, always use a full-sized paper towel and lay it flat over a table
Step 2: Now fold the paper towel vertically into half
Step 3: Again fold the paper towel into another half (you will now get an almost square shape)
Step 4: Now take the folded paper towel and use the open ends to create a pocket to put your coffee grinds and keep it back into the filter cup
Step 5: Put your favorite coffee grounds inside the pocket
Step 6: Remember to fold the outer edges to ensure that the pot lid closes completely
Step 7: Now add hot water (not boiling hot) slowly into the filter cup and let the coffee drip into the pot
Step 8: Now enjoy your morning coffee. This may not taste as great as the coffee flavor you are used to, but you can still manage to have coffee without any filters
What Are Other Alternatives To Paper Towel？
Many coffee enthusiasts may not approve of paper towels as the right substitute for paper filters. If you have similar feelings, here are some alternatives that you may try. Each method has its own set of pros and cons, but as I said these come in handy as a quick-fix solution when you suddenly run out of coffee filters.
Cheesecloth is a cotton cloth used in the making of cheese and it resembles a gauze used for separating liquids from solids. They come in different grades ranging from very fine to open ones. You may use a fine cheesecloth to brew when you have run out of coffee filters.
Use in the same method as mentioned for the paper towels. Fold or cut it into halves to fit your brewing equipment. The biggest advantage of using cheesecloth as a substitute is that the fabric is stronger than paper towels and it will not tear at the time of brewing.
On the downside, not many people have cheesecloth as easily available as paper towels. Even if you do, you will need to cut it and discard it after one use.
Cloth Napkin

Set a cloth napkin on the automatic drip or pour over the basket
If you have no paper towels at hand, you may use a dishtowel or a clean cloth napkin to brew your coffee. To use a cloth napkin as a filter, set it on the automatic drip or pour over the basket (you may use a rubber band to secure the cloth on the top while letting it slightly droop inside).
Now, put two tablespoons of freshly ground coffee inside the napkin and slowly pour hot water (again not boiling hot) into it. Carefully remove the cloth napkin from the mug to prevent the grounds from dropping into the mug and rinse the cloth.
The advantage of using this method is that almost everyone has a clean towel somewhere in the house and this is a reliable method. The cons include the probability of staining the cloth napkin, puddles on the sides of the mug, and your coffee tasting a lot like laundry detergent.
Mesh Sieve
Another way to save your mornings when you run out of coffee filters is using a mesh sieve. To use this option, put two tablespoons of coffee grounds in a measuring cup and pour not-very-hot water into the cup and stir it using a spoon. Let it sit for 5 minutes or more if you prefer a really strong coffee.
Now you can pour out the coffee into a mug using a fine mesh sieve.
The advantage of using this substitute is that it is extremely scalable and you may brew a whole pot of coffee using this method. You can also control how strong you want your coffee to be.
On the downside, a mesh sieve cannot hold the finest coffee grounds that drip into the mug and does not retain the oils that are usually absorbed by the filters. Your coffee may taste different using a mesh sieve, but this certainly better than no coffee!
Can You Use A Paper Towel As A Coffee Filter: The Final Word
Just because you ran out of coffee filters or you don't have access to one while traveling does not mean you have to give up the joy of treating yourself to a delicious cup of Joe. Using paper towels instead is a quick and reliable substitute that can save your mornings.
While coffee purists may disapprove of this method citing various reasons, I feel this is the most sustainable solution. After all, who doesn't have paper towels?
You may also try the other methods mentioned in this post to see what works best for you!

In the context of software or information modeling, a happy path is a default scenario featuring no exceptional or error conditions, and comprises the sequence of activities executed if everything goes as expected. For example, the "happy path" for a function validating credit card numbers would be where none of the validation rules raise an error, thus letting execution continue successfully to the end, generating a positive response.
Process steps for a happy path are also used in the context of a use case. In contrast to the happy path, process steps for alternate paths and exception paths may also be documented.
Happy path testing is a well-defined test case using known input, which executes without exception and produces an expected output.
Happy day scenario and Golden path are synonyms for happy path.

Where and when did Islam originate? Did Ishmael, son of Abraham start this religion?
I want to know from when or which nation the Muslim religion started. Is it from Ishmael son of Abraham?
Islam as a religion was established by Muhammad, a member of the Arabic Quraish tribe from the West-Central part of the Arabian Peninsula in the region of present-day Mecca. Muhammad is a real person who lived from AD 570-632. He claimed to receive a revelation from the archangel Gabriel in AD 610 to be a prophet to the Arabic peoples promoting monotheism and a belief in Allah. His movement started slowly, but when he moved to Medina, it began to gain momentum. Later, Muhammad returned and conquered Mecca. By his death, his troops had conquered much of the Arabian Peninsula. By physical force and persuasion Islam spread across North Africa and the Middle East, reaching India by about the 11th century.
The Old Testament claims that Ishmael, son of Abraham moved into the area we now call "Arabia." It claims that the Arab peoples are the direct descendant of Ishmael. Muslims agree that this is true. They believe that the promised son of Abraham in Genesis is actually Ishmael, not Isaac. They claim that Abraham traveled to Mecca with Ishmael and worshipped the one true God at the Kabba, a stone idol in Mecca. There is not external verification of this claim and no evidence that Abraham made this journey. What we can say for sure is that Ishmael definitely did not establish the religion Islam because he died over two thousand years before the religion was founded by Muhammad. Muhammad himself definitely did not claim that Ishmael founded Islam, but he did claim that he was a prophet in the spirit of Abraham, Ishmael and Moses.
I have a power point on Islam at the web site. Just go to the power point presentation section and click on the appropriate link. It may prove helpful to you in your study of this religion. I also suggest you read the Koran for yourself so that you can be prepared to answer your Mulsim friends as to why Jesus is indeed the Messiah prophesied in the Old Testament.
By the way our organization Apologetics Research Society just sponsored a debate between a Jew (Rabbi Shmuley Boteach) a Muslim (Imam Shabir Ally) and Douglas Jacoby. You might want to get a copy of the DVD. It is very educational and inspirational. It is available at _URL_

Why did the world's most famous airplane stop service?
After a fatal crash killing 113 people and that had many other flaws, airliners decided to cancel the first ever supersonic plane.
At one point of time, the world's first supersonic plane was the most famous plane in the world. Passengers that could pay the high ticket price (five times that of the cost of other flights) could fly across the Atlantic ocean in 3.5 hours in a groundbreaking and unique aircraft. But on June 25th, 2000 a tragic event occurred in Paris's Charles de Gaulle Airport which would ultimately hasten the end of the Concorde.
The Concorde was developed through a collaboration between British Aircraft Corporation and Aerospatiale of France. They gave Air France and British Airways the Concorde model for much less money. There were twenty Concordes built throughout its development and use, six of which were prototypes never used in service.
When it was in the process of being brought to service, the aircraft's test flights produced sonic booms that really bothered people on the ground so they could only fly it over the ocean.
Its first ever passenger flight was on September 26th, 1973 and it started with British Airways flying to Bahrain. Then Air France flew it from Paris to Rio De Janeiro, Brazil.
On July 25, 2000 Air France flight 4590 was scheduled to fly to New York from Paris and had 109 people on board including crew. Right upon take off the plane suffered an error which would, in a few minutes change airplane history.
Five minutes before it took off, another aircraft had taken off but lost a small strip of metal which would end up being fatal. When the Concorde was gaining speed, it ran over that piece from the previous plane that flew up and it hit the engine and it caused fuel to leak out and the engines on the left side couldn't function properly. At this point one of the most famous Concorde photos were created which showed the plane on fire. When the plane caught on fire it was too late to abort takeoff as it already reached the maximum speed allowed. The plane took off but was trying to divert to another airport immediately so it could land and prevent harming passengers but it was unable to.
After two minutes in the air, the plane couldn't stay up any longer and crashed into the Hôtelissimo Les Relais Bleus Hotel, killing 109 passengers and four employees of the hotel.
Air France and British Airways couldn't make money back anymore and a big factor of that was the crash. Tickets to fly on the Concorde were expensive and the ticket money could weight out the maintenance costs, but since passenger levels were going down it was extremely difficult to pay it off. Maintenance prices were also rising too so it made it even more difficult to keep the Concorde in service.
The two companies couldn't manage to keep the Concorde available anymore, so, in 2003 (three years after the crash in 2000), they announced the Concorde would stop service and the last flight ever would occur during June 2003.

Variable Names
Valid Names
A valid variable name starts with a letter, followed by letters, digits, or underscores. MATLAB® is case sensitive, so A and a are not the same variable. The maximum length of a variable name is the value that the namelengthmax command returns.
You cannot define variables with the same names as MATLAB keywords, such as if or end. For a complete list, run the iskeyword command.
Examples of valid names:Invalid names:
Conflicts with Function Names
Avoid creating variables with the same name as a function (such as i, j, mode, char, size, and path). In general, variable names take precedence over function names. If you create a variable that uses the name of a function, you sometimes get unexpected results.
Check whether a proposed name is already in use with the exist or which function. exist returns 0 if there are no existing variables, functions, or other artifacts with the proposed name. For example:
exist checkname
ans =
If you inadvertently create a variable with a name conflict, remove the variable from memory with the clear function.
Another potential source of name conflicts occurs when you define a function that calls load or eval (or similar functions) to add variables to the workspace. In some cases, load or eval add variables that have the same names as functions. Unless these variables are in the function workspace before the call to load or eval, the MATLAB parser interprets the variable names as function names. For more information, see:

Learning Outcomes & Learning Demonstration Statements
Since you will be given credit for the learning you have acquired through your experience, you will need to be able to measure this learning against a course or set of courses that UFV offers. How does this work?
Every course outline at UFV contains a section called Learning Outcomes. A learning outcome is a specific and measureable statement written to describe knowledge and skills that students will have achieved at the end of a course or program. It is the way we as teachers can be sure our students have learned what we intended they would learn in our course.
Learning Demonstration Statements
You have now looked at the learning outcomes for a course or program and have said to yourself, "I can do that!" Learning demonstration statements can help organize your learning in your request to be approved to pursue PLAR and to describe physical or electronic evidene of learning that relates to course or program learning outcomes.
You can see Tips on Learning Statements for more information.
Please use this list of verbs to develop learning statements that best reflect you skills, knowledge and abilities.

To be "stuck in ___" means that something is in a place and isn't coming out very easily. A person can be "stuck in" a room:
The door wouldn't open, and I was stuck in the bathroom for 20 minutes.
In this example:
Hey, um, you've got something stuck in your teeth.
...the speaker says "stuck in your teeth". Obviously, the food isn't inside of the actual teeth. Instead, this sentence means that the food is in between some of her teeth and isn't coming out.
Some other common places where things get stuck include:
I was stuck in traffic for over an hour.
There's something stuck in my throat.
Our car got stuck in the mud.

The production process of optical glass
The raw materials for the production of optical glass are some oxides, hydroxides, nitrates and carbonates, and phosphates or fluorides are introduced according to the requirements of the formulation. In order to ensure the transparency of glass, the content of colored impurities, such as iron, chromium, copper, manganese, cobalt, nickel, etc., must be strictly controlled. When ingredients are required, accurate weighing and uniform mixing are required. The main production processes are smelting, forming, annealing and inspection.
1. There are single crucible batch smelting method and tank kiln (see kiln) continuous smelting method for smelting. Single crucible smelting method can be divided into clay crucible smelting method and platinum crucible smelting method. No matter what kind of smelting method is used, it needs to be stirred with a stirrer, and the temperature and stirring are strictly controlled to make the glass liquid reach a high degree of uniformity. Clay crucible can smelt most crown glass and flint glass, with low cost, and is used when the melting temperature of the glass exceeds the service temperature of platinum. The platinum crucible can smelt high-quality glass that has a serious corrosive effect on the clay crucible, such as heavy crown, heavy barium flint, rare earth glass and fluorophosphorous glass. The platinum crucible is heated by electricity, generally a silicon-carbon rod or silicon-molybdenum rod electric furnace is used. However, high-frequency heating can be used to manufacture glass that has a high tendency to crystallize, requires rapid cooling, and has certain requirements on the atmosphere.
Since the 1960s, various countries have successively adopted platinum-lined continuous tank smelting to greatly increase the output and quality of optical glass. This is the main trend in the development of optical glass production technology.
2. The molding methods for molding optical glass include the classical crucible method, the rolling method and the pouring method. However, leakage molding (using a single crucible (Or continuous melt flow out of the material liquid), can directly draw rods or drop material to form large-size blanks, improve the utilization rate of gobs and the yield rate.
3. Annealing In order to eliminate the internal stress of the glass to the greatest extent and improve the optical uniformity, a strict annealing system must be formulated for precision annealing.
4. The indicators for inspection and measurement include: optical constants, optical uniformity, stress birefringence, fringes, bubbles, etc.
The raw material of optical glass is high-quality quartz sand as the main material, and auxiliary materials are appropriately added. Due to the high refractive index, low dispersion and good chemical stability of rare earths, optical glass can be produced, which can be used to make lenses for advanced cameras, video cameras, telescopes and other advanced optical instruments. For example, a kind of lanthanum glass with excellent optical properties containing lanthanum oxide lao360% and b2o340% oxide is an indispensable optical material for manufacturing high-end camera lenses and periscope lenses. In addition, using the radiation protection properties of some rare earth elements, radiation protection glass can be produced.

Dynamic Witness improves Windows 2012 Cluster High Availability
Posted by Alin D on February 21, 2013
Determined to make Windows Failover Clusters as resilient as possible, Microsoft has once again made significant improvements to its quorum mechanisms in Windows Server 2012. The Dynamic Quorum Management option allows the cluster to dynamically adjust the quorum (or majority) of votes required for the cluster to continue running. This prevents the loss of quorum when nodes fail or shut down sequentially, allowing the cluster to continue running with less than a majority of active nodes.
In addition to dynamic quorum, multisite geoclusters now benefit from the ability to specify which nodes receive votes and which ones don't. This allows you to bias a particular site (e.g., the primary site) to have the controlling votes, or nodes, to maintain quorum. This also prevents a split-brain scenario from occurring as the secondary site tries to update the cluster database when the primary site is down
Configuring Dynamic Quorum in Windows Server 2012
The principle behind quorum in a failover cluster environment is to ensure that only a majority of nodes can form and participate in a cluster. This prevents a second subset of nodes from forming a separate cluster that can access the same shared resources in an uncoordinated fashion, which can lead to corruption. When nodes are shut down or fail, there are fewer active nodes remaining to maintain the static quorum value of votes needed for the cluster to function. The new Dynamic Quorum Management dynamically adjusts the votes of remaining active nodes to ensure that quorum can be maintained in the event of yet another node failure or shutdown.
There are a few requirements that must be met before the Dynamic Quorum mechanism kicks in. First, Dynamic Quorum must be enabled, which it is, by default, in Windows Server 2012. The Failover Cluster Manager can be used to view or modify the Dynamic Quorum option by running the Configure Cluster Quorum Wizard. Start the wizard by highlighting the cluster in the left-hand pane, right-clicking on it, selecting More Actions and then choosing Configure Cluster Quorum Settings.
The Quorum Wizard prompts you to select from several different quorum configurations depending on your environment (Typical, Add/Change or Advanced). By default, the cluster will use the typical settings for your configuration to establish the quorum management options. You can also add or change the quorum witness if one was selected during the installation process.
To view or change the Dynamic Quorum Management option, use the Advanced quorum configuration option, as seen above. Stepping through the Quorum Wizard, it will prompt you to Configure Quorum Management. This is where you can view or change the Dynamic Quorum option.
You can also view or modify the cluster's Dynamic Quorum setting by using PowerShell cmdlets. The first cmdlet, Get-Cluster, as shown in below, reveals the current Dynamic Quorum setting (0=disabled, 1=enabled). You can then use PowerShell to enable Dynamic Quorum by establishing the variable $cluster with Get-Cluster and then set the property DynamicQuorum to a value of 1.
With Dynamic Quorum enabled, the next condition that must be met is that the cluster must be up and running and currently sustaining quorum based on the initial cluster configuration. The final condition for Dynamic Quorum to work is that any subsequent node failures or shutdowns must be experienced sequentially — not with multiple nodes going down at the same time. A lengthier cluster regroup operation would occur if multiple nodes exited the cluster simultaneously.
You can use PowerShell to view the number of votes and observe the inner workings of the Dynamic Quorum mechanism. By default, each server in the cluster gets a single vote, or NodeWeight. When Dynamic Quorum is enabled, an additional property called DynamicWeight is used to track a server's dynamic vote toward quorum. The cluster will adjust a node's dynamic weight to zero, if necessary, to avoid losing quorum, should another node exit the cluster. The PowerShell cmdlet reveals the NodeWeight and DynamicWeight for a two-node cluster.
Dynamic Quorum allows cluster nodes to be individually shut down or fail to the point where just a single node is left functioning ("last man standing"). Just as quorum is dynamically adjusted downward as nodes fail or are shut down in the cluster, quorum is adjusted upward as nodes are rebooted back into the cluster.
Using weighted votes to assign nodes
The other major enhancement to the quorum mechanism in Windows Server 2012 is the ability to specify which nodes in a cluster receive a vote. As mentioned, all nodes receive a vote that contributes toward quorum by default. In multisite geocluster configurations, it may be beneficial to give nodes in the primary site a vote to ensure they keep running in the event of a network failure between sites. Nodes in the secondary site can be configured with zero votes so they cannot form a cluster.
You can use the Quorum Wizard (Advanced Quorum Configurations) to configure whether a node receives a vote. The wizard also allows you to see how Node1 is given a vote and Node2 is not.
Alternatively, you can use PowerShell to specify whether a node receives a vote. Use the Get-ClusterNode cmdlet to set the NodeWeight for Node2 back to 1 so that it receives a vote.
Windows Server 2012 has made significant improvements to the quorum mechanism, resulting in more resilient Failover Clusters. Dynamic Quorum Management takes the worry out of whether enough servers are active to achieve or maintain quorum if systems should fail or shut down. Multisite geoclusters also use weighted votes to specify which primary site should continue running in the event of intersite network failures.

Partnership Against Wildlife Crime Scotland (PAWS)
Wildlife crime can involve anything from poisoning a golden eagle to cracking open freshwater pearl mussels. Rare species are put at risk, more familiar ones, like the badger or deer, suffer cruel torture and death.
In fact, wildlife crime threatens a far greater range of creatures and plants than you might imagine, even damaging the environment on which they depend. In short, it's the illegal destruction and theft of animals, plants and habitats, both in the countryside and urban areas.
It damages Scotland's environment and its reputation and we have a duty to the rest of the world to look after our internationally important species and habitats.
The Partnership for Action Against Wildlife Crime in Scotland - PAW Scotland - includes the police, land managers, conservationists and the Scottish Government. We have come together to fight this crime against Scotland.

Modulation of laser induced-cracks inside a LiF single crystal by fs laser irradiation at multiple points
Spotlight summary: One of the most attractive and unique capabilities in laser material processing is that of selectively modifying the optical and physical properties of materials through structural changes constrained to within the focal volume. Femtosecond (fs) laser processing in transparent materials has received special attention since the laser beam can be tightly focused, and therefore induce various nano and microscale structures such as cracks, dislocations, and voids inside the material without compromising the properties of other regions not so highly excited by the laser, including the material's surface. Such structural changes inside the material are extremely difficult to achieve through other processing technologies. To make use of this unique benefit of fs laser processing with a higher precision, the size and shape of the structures need to be well controlled, since they critically affect the volume and properties of the laser-processed region. Therefore, finding new ways for accurately controlling these structures and achieving a deeper understanding of the mechanisms that lead to structural changes following fs laser pulse irradiation is of great importance.
Recently, the authors of this article showed that thermal stress waves can be generated inside rock salt crystals following fs laser pulse irradiation. These waves then propagate away from the fs laser-excited region, and subsequently induce permanent dislocations in certain orientations of the crystal structure. Cleverly using their previous discoveries, the authors reveal in this Optics Express article how the fs laser-induced dislocations and thermal stress waves affect the formation of fs laser-induced cracks, and find a way to control the size and shape of these cracks in LiF by irradiating with three pulses, either sequentially or simultaneously. First, to understand the effects of dislocations on the formation of fs laser-induced cracks, two sequential pulses are applied inside the LiF crystal, producing dislocation bands in the crystal. A third pulse is then applied for which the dislocation bands can either affect or not the formation of cracks, showing that these bands, due to the higher mechanical strength, can prevent the formation of fs laser-induced cracks. Next, the authors use three simultaneous pulses instead, and control the interference of the fs laser-induced stress waves where the crack formation is expected. If compression waves are generated by the interference of the pulses and propagate from the tip to the center of a fs laser-induced crack in the time range of 2400-3000ps, the formation of fs laser-induced cracks is highly disturbed by the compression waves, and the length of the crack is shorter than the one without the waves. On the other hand, with a different distribution of the three simultaneous pulses, the authors generate tensile stress near the crack at 3500ps without strong compression waves, and find that this tensile stress helps the propagation of the crack, leading to the production of longer fs laser-induced crack.
In summary, the authors demonstrate sophisticated control of fs laser-induced cracks by using the permanent and transient change of mechanical properties in LiF: the dislocation bands and thermal stress waves, induced by fs laser pulse irradiation. The results reported in this article not only show control of fs laser-induced cracks but also potentially provide a new way of controlling many other types of fs laser-induced structures, possibly leading to the generation of new optical and physical properties in materials.

- This paper takes a financial market perspective in examining the relationship between oil prices, the US dollar and asset prices, and it exploits the heteroskedasticity for the identification of causality in a multifactor model. It finds a bidirectional causality between the US dollar and oil prices since the early 2000s. Moreover, both oil prices and the US dollar are significantly affected by changes in equity market returns and risk. By contrast, oil prices did not react to changes in these financial assets before 2001. The paper provides evidence that this may be explained by the increased use of oil as a financial asset over the past decade, which intensified the link between oil and other assets. The model can account well for the strong and rising negative correlation between oil prices and the US dollar since the early 2000s, with risk shocks and the financialisation process of oil prices explaining most of the strengthening of this correlation.

A protégé is a person who receives special protection and promotion from someone more established in a field. If your boss introduces you as his newest protégé, you're off to a good start in your career.
Essentially, a protégé is a teacher's pet, someone who is given special status or favors. Often, the word is used for someone who has special standout talent and is taken up as an upcoming star or powerhouse. The word's original associations, however, have nothing to do with talent and everything to do with how a person treats the protégé — the source of the word means "protection."

How to handle a hung flow
DavidBrickell 270001MT2R Visits (13274)
Sometimes when developing a flow we find that the flow becomes non-responsive. This can be caused by a few different reasons but one of the most common is that the flow is stuck in a logic loop.
This can be caused by poor code design or design of the flow itself. Even after identifying and fixing the logic within the flow, you are still stuck with the task of replacing the deployed flow within the Broker.
WebSphere Message Broker has built in recovery measures. This means, if the Broker detects that the EG has crashed or stopped unexpectedly, it will try to restart this process. To avoid the flow going back into its hung state, you should shut down the input source. For example, you can disable the input queue if using MQ as your input source. After this is done, you can kill the EG process. When the EG restarts you will see an error stating the message flow couldn't connect to the input source. From this point you can stop the message flow and then delete it.
This will allow you to redeploy the corrected flow to replace the old one.


How to Sell a Property Held in a Revocable Trust
by Fraser Sherman, Demand Media Google
 If you follow state law, selling property in a trust should be simple.
 Selling a house in a revocable trust isn't complicated. If you've set up a trust and appointed yourself as trustee, you can manage the real estate just as if the title were still in your name. If you're incapacitated and your successor trustee steps in to manage your assets, she can do the same. Most elements of the sale -- negotiating a price, getting a home inspection, attending the closing -- are no different from when you sell property as yourself, rather than as a trustee.
 Step 1
 Research deed law in your state. Every state requires a "grantor" or seller -- you, in your job as trustee -- to sign a deed conveying property to the "grantee" or buyer. Some states also require the grantee to sign the deed, and some want one or possibly two witnesses to sign the deed as well.
 Step 2
 Show a copy of the trust documents to the title company. The company's job is to research your property's ownership history and confirm nobody else has a claim on it. Reviewing the trust documents helps the title company establish that the trust has a clear title and the right to sell it.
 Step 3
 Sign the deed transferring ownership to the grantee. You do this at the closing, where you sign as, for example, Jane Smith, trustee of the Jane Smith Trust. If you and your spouse have a joint revocable trust, the bank will want both of you to sign. Even if you have the authority to sell the house, the bank will want the security of two signatures.
 Step 4
 Complete any other requirements state law requires, such as having the deed notarized or having someone witness your signature. File the deed with the appropriate county office, which if often called the "registry of deeds."
 - If you transfer your personal home to your revocable trust's control, the IRS still regards you as the owner for tax purposes. If you live in the house for two of the five years before you sell it, you can exempt some of the sale proceeds from capital gains tax, even though the trust technically holds title to the house.

The drag coefficient of a rigid spherical particle deviates from Stokes law when it is put into a near-critical fluid mixture in the homogeneous phase with the critical composition. The deviation is experimentally shown to depend approximately linearly on the correlation length of the composition fluctuation far from the particle, and is suggested to be caused by the preferential adsorption between one component and the particle surface. In contrast, the dependence was shown to be much steeper in the previous theoretical studies based on the Gaussian free-energy density. In the vicinity of the particle, especially when the adsorption of the preferred component makes the composition strongly off-critical, the correlation length becomes very small as compared with. This spatial inhomogeneity, not considered in the previous theoretical studies, can influence the dependence of on. To examine this possibility, we here apply a renormalized local functional theory, describing the preferential adsorption in terms of the surface field. This theory was previously proposed to explain the interaction of walls immersed in a (near-)critical binary fluid mixture. The free-energy density in this theory, coarse-grained up to the local correlation length, has a very complicated dependence on the order parameter, as compared with the Gaussian free-energy density. Still, a concise expression of the drag coefficient, which was derived in one of the previous theoretical studies, turns out to be valid in the present formulation. We show that, as becomes larger, the dependence of on becomes distinctly gradual and close to the linear dependence.

Key Opinion Leaders
A opinion leader is an active speaker, communicator or commentator who interprets often complex messages for other people. Oftentimes an opinion leader is held in high esteem, meaning that his / her messages are considered as reliable and factual. Key opinion leaders (KOL) are those people who are recognized and followed by a large number of other people. Good examples are:
- Industry analysts from Gartner, Forrester, IDC...or other market research organizations
- key journalists covering your field of activity working for large media (the national press, key websites)
- key politicians showing an active interest in your business
Whichever sector you are working in, keeping an eye on what your industry specific KOL are talking about can help you to identify strengths, weaknesses, opportunities and threats.
How to track what KOL are talking about
The first step is to create a list (or lists) of the KOL for your sector or area of interest.
Using this and a query you can create a bar chart that shows the number of articles citing them or written by them.
Here is an example based on KOL for diabetes.
If you want to go a step further, you can combine the KOL list with a list of key subjects that you would like to focus on.
You can then create Digimind analysis based on these two lists.
Here is one created using a list of diabetes KOL and important diabetic healthcare themes:
You can run this type of analysis on any type of Digimind graph that uses two lists (for more details please follow this link).

This book was not very helpful at all. Simply reviewing old test answers would have the same benefits. The authors clearly think very highly of themselves and find themselves amusing. In one answer they berated the answer author for missing an important point regarding whether both individuals in the hypothetical would be considered merchants. The answer author had addressed it, the book authors were just too busy listening to themselves talk to notice. Many of the points would be helpful, "it is important that the author give a definition for offer", if they followed it up with the definition for offer. I bought this book because I am poor, and working full time and don't have time or money for Barbri or Kaplan. When they are critiquing an answer, I want to know the right answer and the substance of what is missing, not simply that the answer author was wrong followed by some lame pun the book authors find hilarious.

The volume of a $d$ dimensional hypersphere of radius $r$ is given by:
$$V(r,d)=\frac{(\pi r^2)^{d/2}}{\Gamma\left(\frac{d}{2}+1\right)}$$
What intrigues me about this, is that $V\to 0$ as $d\to\infty$ for any fixed $r$. How can this be? For fixed $r$, I would have thought adding a dimension would make the volume bigger, but apparently it does not. Anyone got a good explanation?

Think about the square of side length $1/2$. What is its volume in $\mathbb{R}^d$? – JavaMan Sep 23 '11 at 18:53
Imagine a square of side length $\frac{1}{2}$: the area is $\frac{1}{4}$. A cube of edge length $\frac{1}{2}$ has volume $\frac{1}{8}$. A hypercube of edge length $\frac{1}{2}$ has hypervolume $\frac{1}{16}$; etc. For a cube, whether going to the "next dimension" increases the total hypervolume or decreases it (as a scalar) depends on whether the edge side was less than $1$ or more than $1$. That suggests to me that "adding a dimension" does not, in and of itself, necessarily mean "making the volume bigger"... – Arturo Magidin Sep 23 '11 at 18:55
What about a sphere of radius $10^{10}$? The volume eventually goes to zero :-) – probabilityislogic Sep 23 '11 at 19:03
_USER_: The point is that simply "adding a dimension makes things bigger" doesn't work: it's not just about the dimension, there are other factors at play. – Arturo Magidin Sep 23 '11 at 19:26

I suppose you could say that adding a dimension "makes the volume bigger" for the hypersphere, but it does so even more for the unit you measure the volume with, namely the unit cube. So the numerical value of the volume does go towards zero.
Really, of course, it is apples to oranges because volumes of different dimensions are not commensurable -- it makes no sense to compare the area of the unit disk with the volume of the unit sphere.
All we can say is that in higher dimensions, a hypersphere is a successively worse approximation to a hypercube (of side length twice the radius). They coincide in dimension one, and it goes downward from there.

The reason is because the length of the diagonal cube goes to infinity.
The cube in some sense does exactly what we expect. If it's side lengths are $1$, it will have the same volume in any dimension. So lets take a cube centered at the origin with side lengths $r$. Then what is the smallest sphere which contains this cube? It would need to have radius $r\sqrt{d}$, so that radius of the sphere required goes to infinity.
Perhaps this gives some intuition.

I'm not seeing why the bricks each have volume at most $\left(2\sqrt{\frac{2}{n}}\right)^{n/2}.$ Shouldn't this be multiplied by a factor of $2^{n/2}$ since the other coordinates have absolute value at most $1$? This doesn't change the limit obviously, but some enlightenment would be nice. – cats Feb 14 '13 at 8:30
Let $X_j$ be a sequence of independent random variables with uniform distribution in the interval $[-r,r]$ (i.e. you are picking an infinite sequence of random numbers from the interval). The probability that $(X_1, \ldots, X_d)$ lies in your hypersphere, i.e. that $R_d = X_1^2 + \ldots + X_d^2 \le r^2$, is $V(r,d)/(2r)^d$ (which by scaling doesn't depend on $r$, so let's call it $P(d)$). Of course $P(d) \to 0$ as $d \to \infty$, but the point is that it goes to 0 faster than an exponential in $d$. Indeed, by the theory of large deviations, for any $t > 0$ we should have $P(R_d \leq t d) \approx e^{-d I(t)}$ as $d \to \infty$ for some function $I(t)$, where $I(t) \to \infty$ as $t \to 0+$.

Consider the distance from the center of the sphere of radius $R$ in $\mathbb{R}^n$ to the corner of its enclosing cube: $R\sqrt{n}$. This is like covering the surface of the sphere with a layer of tall corners.
For $x=(x_1,x_2,\dots,x_n)\in\mathbb{R}^n$, define $$ Q(x)=x\frac{|x|}{\max_i|x_i|}\tag{1} $$ $Q$ maps a sphere to its enclosing cube. As described above, $\frac{|Q(x)|}{|x|}$ reaches a maximum of $\sqrt{n}$ in the corners. To be exact, $$ \frac{|Q(x)|^2}{|x|^2}=\sum_j\frac{|x_j|^2}{\max_i|x_i|^2}\tag{2} $$ By considering each $x_i$ to be normally distributed and using homogeneity of $(2)$, we get that the mean of $\frac{|Q(x)|^2}{|x|^2}$ over the sphere is $\frac{n+2}{3}$. Thus, the rms average of $\frac{|Q(x)|}{|x|}$ is $\sqrt{\frac{n+2}{3}}$. In this way, the volume of the cube should be approximated by $\sqrt{\frac{n+2}{3}}^{\;n}$ times the volume of the sphere. This grows faster than any $R^n$.

Let me develop on the idea presented by Christoph Pegel in the comments of this post.
The first thing is that the volume depends on the radius. $n$-ball or cube of radius $r$ has $r^n$ times bigger volume than that of radius $1$. One should expect then, that at least for big radii the volume of the ball will increase (as it is in the case of the unit cube $[-1,1]^n$ of volume $2^n$).
However, the thing is that somebody once decided (could they decide otherwise?) that Fubini theorem would be nice and $n$-dimensional volume of $[0,1]^n$ will be the same as $(n+1)$-dimensional volume $[0,1]^n\times [0,1]$ -- even though of course one is much smaller than the other!
That's the key point - volume is invariant under cartesian product with the unit interval - like it or not.
So, as Christoph Pegel says it is reasonable to compare volume of the ball $B^n$ with volume of the cylinder $B^n\times [-1,1]$. The second is of course $2$ times bigger but it is a matter of radius as already discussed.
Note that if we compare $B^{n+1}$ with $B^n\times [-1,1]$, we notice that only the zero section is the same. At level $t$ the ball is smaller with radius $\sqrt{1-t^2}$. That means that its volume is $(1-t^2)^{n/2}$ times smaller! This function converges to zero with $n$ (and so does its integral) and thus there's no wonder that it kills any geometric growth (where multiplicative factor $>1$ is constant).

Like many of America's house museums, Mount Clare, the 18th-century Baltimore plantation home of Charles Carroll, struggles to maintain relevance, sustain its mission and remain financially sound. More recently formed museums, such as the Tenement Museum of the Lower East Side of Manhattan, have begun to recognize their capacity as platforms for dialogue and social justice and the necessity of engaging their local communities, providing a useful model for Mount Clare Museum House. Engaging with its southwest Baltimore community would enable Mount Clare to fully support an educational mission that resonates with the local population, while preserving the role of the historic site. The purpose of this paper is to explore Mount Clare Museum House in terms of its relevance to various levels of community. This will be accomplished by examining Mount Clare's governing boards and mission statement, by considering its interpretation and outreach programming, by researching community opinion, and by comparing it to aspects of the Tenement Museum. The intention is to create a better understanding of why past attempts to broaden Mount Clare's interpretive scope have failed, to help the museum move forward in reaching out to the community, and to reflect on the public it seeks to educate.

Gaurab Aryal (The Australian National University) and Maria F. Gabrielli (CONICET, Universidad Nacional de Cuyo) are Testing for Collusion in Asymmetric First-Price Auctions.
ABSTRACT: This paper proposes fully nonparametric tests to detect possible collusion in first-price procurement (auctions). The aim of the tests is to detect possible collusion before knowing whether or not bidders are colluding. Thus we do not rely on data on anti-competitive hearing, and in that sense is 'ex-ante'. We propose a two steps (model selection) procedure: First, we use a reduced form test of independence and symmetry to shortlist bidders whose bidding behavior is at-odds with competitive bidding, and Second, the recovered (latent) cost for these bidders must be higher under collusion than under competition, because collusion dwarfs competition, hence detecting collusion boils down to testing if the estimated cost distribution under collusion first order stochastically dominates that under competition. We propose rank based and Kolmogorov-Smirnov (K-S) tests. We implement the tests for Highway Procurement data in California and conclude that there is no evidence of collusion even though the reduced form test supports collusion.

CloudMounter: Mounting cloud storages and web servers to Mac as local disks
By Team CR
With CloudMounter, a user gets access to various cloud storages and web servers elegantly and easily. It keeps the user's online data solidly protected. It gets the user the most out of DropBox encryption, Amazon S3 encryption, cloud encryptionFTP encryption as well as Google Drive, OneDrive and WebDAV servers.
CloudMounter helps encrypt user personal data stored on cloud disks and remote servers.This protects the data from any kind of unwanted access. CloudMounter uses the Advanced Encryption Standard (AES) when this feature is enabled by the user. It uses AES with a 256- bit key length in order to translate data into different forms so that the people who have access to the password can only read and manage it.
Encrypted data will be at the disposal if the user wants to restrict third-party users from gaining access of the private data, in case somehow they obtain access of one of the user's machines where the credentials of logging in were saved. The personal files would appear confusing and gibberish thus making them protection stronger.
A user's cloud and remote server files are absolutely protected with the CloudMounter encryption functionality. He can tune the data encryption and secure remote servers and cloud accounts so that they can only be accessed from the user's CloudMounter. The encryption works that way that if someone somehow obtains the access to the user's storages from a different device, they will only see confusing nonsense.
Not only the user's multiple DropBox, Google Drive and Microsoft OneDrive accounts are easy to access and work with, But also a user doesn't even have to leave the oh so familiar Finder to work with online and remote files.
A user can indicate a password and verify it and CloudMounter highly recommends setting a password hint to be able to recover it in the future. A user must also tick the optional boxes if he would like to add the password to the keychain. To mask the encrypted files on the user's local machine, he will need to lock the encrypted directory by using the "Lock" context menu. He will be able to unravel these files later by using the "Unlock" option from the same context menu. When the encryption is no longer needed, the user would like to decipher the directory, he has to simply select the "Decrypt" option from the context menu, enter the password and confirm actions.
The primary window in this application is a connections manager where each and every service supported has been assigned to single buttons. In order to mount a drive that is required, the user can choose any corresponding service.
CloudMounter works perfectly well with the macOS Keychain and the entire user's personal data is securely kept there. A user can connect to as many accounts of each supported service as the user may need. The increases the user disk space tremendously. All the user needs is to free lots of room on the hard drive and an internet connection access to your clouds and remote servers.

Has GST benefited healthcare sector?
India's healthcare sector has been a focus area during the Narendra Modi government's first three years. There have been several well-intended policies.
India's healthcare sector has been a focus area during the Narendra Modigovernment's first three years. There have been several well-intended policies. For example, the National Health Policy 2017, which has set several goals, including the progressive roll-out of the universal health coverage (UHC) that will bring in a significantly large population under the public healthcare system.
Further, finance minister Arun Jaitley's third Union Budget earlier this year proposed making drugs more affordable by making amendments to the Drugs and Cosmetics Act, and bringing wellness and preventive care to the forefront. The Union Budget also recommended making certain structural changes in medical education. Keeping healthcare costs under control is important. Towards that, the government did take a strong decision to drastically slash prices of medical devices.
Now, with the implementation of the goods and services tax (GST) across the country, the expectation was that healthcare services would overall become affordable for the masses. But has that happened? Well, the healthcare sector has been granted full exemption from GST. So, there are no taxes and hence, theoretically, it should be affordable. But what exactly is the impact of GST on the healthcare sector?
At the outset, "healthcare services" means any service by way of diagnosis or treatment or care for illness, injury, deformity, abnormality or pregnancy in any recognised system of medicines; it also includes services by way of transportation of the patient to and from a clinical establishment. And "clinical establishment" typically means a hospital, nursing home, clinic, sanatorium, etc.
Under the new indirect tax regime, many sectors have benefited from the increased credit due to minimal blockage of credit and enhanced fungibility of credit between goods and services.
However, this is not true for the healthcare sector. The reason is that because complete exemption has been granted to healthcare services, it thereby means that the input tax credits cannot be availed. Consequently, this leads to a lot of input tax cost, which has become a burden on healthcare services.
Therefore, there is an urgent need to grant benefits under GST due to the key reason that affordable medical care and healthcare should be accessible to every individual in India as a matter of right. Further, increase in tax cost for the healthcare sector would mean a basic necessity like healthcare becoming expensive for the common man. Increasing the tax burden would be hugely detrimental to the health of the masses.
In fact, the current stage of development of the healthcare industry in India cannot afford the burden of extra tax cost. The GST regime promotes seamless flow of credit across goods and services, and removes cascading effect of taxes. Considering the exemption on healthcare services (output side), GST paid on procurement (for example, medicines, consumables, etc) by such clinical establishments will be a huge sticking cost, making healthcare services expensive. Since the ultimate burden of GST is passed on to the end-consumers—patients in this case—it is prudent that the GST input tax cost on the healthcare sector be removed. The government should re-look at this area to ensure that the ultimate objective of providing affordable healthcare services to the vast population of India is achieved.

The majority of models developed to describe the actively mode-locked operation of diode lasers have been generated for diodes having one antireflection coated facet. The basic starting point of such models is the assumption that the residual facet reflectivity can be ignored. In the present paper, we employ a model developed specifically to deal with mode-locked operation for diodes with a significant facet reflectivity. Experimental observation of mode-locked operation for different facet reflectivities shows that the model provides a good description of this mode of operation. It is to be emphasized that the comparison between model predictions and experimental observations is basically exact; no fitting parameters are used, and the significant diode parameters are independently measured. This model, thus validated, is used to explore how low the residual facet reflectivity needs to be to be treated as negligible. It is shown that, even for very low values, this facet reflectivity has a strong influence on the dynamical behavior of the mode-locked diode laser.

Phonetic Alphabet - Memorizing Numbers
Quick Notes - Phonetic Alphabet:
 - Memorize the phonetic alphabet and you will use it to memorize numbers for the rest of your life.
Using the Phonetic Alphabet for remembering numbers is a simple memorization strategy that only takes a few minutes to learn and you will use it for the rest of your life.
The Phonetic Alphabet
To be able to remember a long number, you must first learn the phonetic alphabet. Each number in the phonetic alphabet (0-9) symbolizes a sound:
0 - has a Z, S or a soft C sound
1 - has a T or D sound
2 - has a N sound
3 - has a M sound
4 - has a R sound
5 - has a L sound
6 - has a sh or ch sound
7 - has a K, hard C, or hard G sound
8 - has a F, V, or ph sound
9 - has a B or P sound
Take some time to memorize the phonetic alphabet. You will want to be able to recite it easily before you can begin to use it. After you can recite the phonetic alphabet smoothly, it is time to start associating your numbers to words or images. Our article on memorizing numbers will teach you exactly how to do this. You will soon be able to remember a phone number or any long number the first time you hear it.

Preparing for the hearing
If you made a submission and indicated that you wished to speak to it, then make sure you reinforce your case by presenting to the hearing.
The hearing report
Before the hearing, Environment Southland compiled a hearing report – a 700-page document (called the section 42A report), which provides the Hearing Commissioners with a summary and analysis of submissions, and makes recommendations on possible amendments to the proposed plan.
The Hearing Commissioners don't have to agree with the recommendations contained in the s42A report, but it is still a useful tool to help understand how the submissions have affected council's thinking.
Can B+LNZ help me prepare for the hearing?
We ran eight workshops, to help farmers prepare. These covered:
- What you can expect at the hearing
- What makes a powerful farmer hearing statement
- How to gain traction with the decision makers
- A refresh on the key issues and a heads up on where council thinking is changing
- What to include in your hearing statement.
What if I missed the workshops?
The workshop resources included a booklet and videos, which you can download on this page. View the powerpoint presentation to pick up tips on how to be as effective as possible on the day.
Key areas to consider
We have created a summary of key areas you may which to address called "The Song Sheet". It covers:
- The policy/rule to consider
- What the notified plan said
- What B+LNZ submitted
- Environment Southland's recommendations to the hearing panel (s42A report)
- Some ideas for farmers to consider in their hearing statement
The eight key areas summarised in the song sheet are:
- Physiographic zones
- Pre-empting limit setting process
- Dairy conversion
- Intensive winter grazing
- Stock exclusion
- Cultivation setbacks
- Tile drains
- Farm Environment Plans

Research studying the brain can be slow, complex, and costly, often requiring the efforts of many scientists and institutions to advance progress. To meet the challenges posed—and promises offered—by brain science, representatives from Australia, Japan, Korea, and the US have declared an intent to create an International Brain Initiative. This initiative comes out of a meeting held recently at the Australian Academy of Science in Canberra, Australia.
In the declaration of intent, which scientists are calling the "Canberra Declaration," the signatories agreed to ally with one another to maximize efficiency and impact; combine perspectives from multiple stakeholders, including government, academia, and industry; and commit to sharing data when possible.
One particularly unique focus of the initiative is on the ethics of brain data research:
"The initiatives therefore commit to collaborate in the fields of neuro-ethics, agency, responsible data stewardship, and cerebral privacy protection. They also commit to engage in a meaningful dialogue with citizens, patients, and all relevant communities to understand their concerns and communicate transparently on the opportunities and challenges arising," reads the declaration.
The initial members of the International Brain Initiative are the Australian Brain Alliance, the Japan Brain/MINDS Project, the Korea Brain Initiative, the EU Human Brain Project, and the US Brain Initiative, according to the Kavli Foundation, which supports the US Brain Initiative.

Localités and Early Modern Britain
This article was originally published in the journal Research and Review Series, no. 7.
In early modem England local identity often was more important than national identity, and "country" as often meant one's native shire as one's nation state. In 1710, a young German gentleman visited London and kept a diary in which he noted unique British customs. He wrote at length about a cockfight he witnessed. He learned that "cocks from the same neighbourhood or county do not willingly attack each other." English cocks had a county identity or mentalite. While the sociobiological truth of this animal behavior might be doubted, the English believed it to be true. Cockfights took place mainly between the prize cocks of country squires from neighboring shires. A 1685 advertisement gave advance notice of "a great Match of Cocking, between Leicestershire and Oxfordshire Gentlemen..., in Leicester." In 1710, Surrey and Hampshire gentlemen fought a cock match after May horse races, while, after a Peterborough horse race in July,there were to be several days of cock-fighting pitting "the Gentlemen of the Counties of Northampton and Lincolnshire against the Gentlemen of the County of Huntington, and Isle of Ely and Cambridge." Cocking and horse racing were part of a gentry "theatre of honour" and of provincial reciprocity and exchange networks. And cocking, at least, reinforced county not national identity.

WHIDDEN GUNWORKS HYDRAULIC FORM DIE INSTRUCTIONS
Gather all parts of the Hydraulic Form Die Kit to include: the hydraulic form die body with lock ring, the piston, the appropriate shell holder (void of the fired primer discharge hole) and the bottle used to fill the case with either water or oil, your choice. Also, not included in the kit, you will need a few fired primers, case lube, a hammer and safety glasses.
- Install the shellholder into the press as normal.
- Install the hydraulic form die into the press just as you would with any other sizing die. With the ram of the press in the up position, install the hydraulic form die and allow the die to make contact with the top of the shell holder. This will set the headspace to the correct location with the die system. Secure the lock ring to the die body.
- Once contact is made between the shellholder and the hydraulic form die lower the ram.
- Insert a fired primer into the base of the brass to be formed.
- Lube the brass and insert the brass into the shellholder and raise the ram completely allowing the brass to enter the hydraulic form die.
- Using the liquid bottle, containing either water or oil, fill the case to about the top of the die body itself.
- Insert the piston into the top of the die.
- (CAUTION) If you haven't done so yet, put your safety glasses on.
- Ensure your safety glasses are on properly. (Obviously this is important)
- Pick up the hammer. We have found that a light to medium weight hammer works best and hitting the piston with several fast strikes (2 to 3) seems to yield the best results.
- Strike the piston.
- Lower the ram of the press and remove the case from the shell holder.
- Repeat steps 1-12 to form the next piece of brass.
Helpful tip: Water is much easier to cleanup and evaporates off the floor much more quickly.
Thanks for using the Whidden Gunworks Hydraulic Form Die System.

Aircon Servicing in Boon Lay
Boon lay – an epic neighborhood of Jurong West
There is some the neighborhood in Singapore and boon lay is the famous one. Jurong West town consist boon lay. It has roughly corresponded border to the subzone of URA. Besides this, many people confused boon lay with boon lay planning area. This planning area is situated in the South of this neighborhood.
Chew Boon Lay was a famous businessman, and he inspires the name of this subzone. From the nineteenth century to the twentieth century, he owned most of the land of this neighborhood. But later on, it was captured by the colonial government and later on used by them war department. Previously it was a village, and in the year 1940, it had a population of 420. In 1969, boon lay began to develop and after that various building, and GBF flats were built in 1974. Also, West Coast GRC had divided, and this subzone is the part of that divisions.
About neighboring areas
Taking about its neighboring areas then they are seven in numbers. These following neighbors surround Boon Lay:
- Hong Kah
- Kian Teck
- Chin Bee
- Taman Jurong
There are very few estates which are built by the private sector. Otherwise, government officials made rest of the buildings. Here are the streets of boon lay:
- Avenue of Boon Lay
- Boon Lay place and,
- Boon Lay Drive
About transportation facilities
Taking the main roads of boon lay then here are their names:
- Boon lay way
- Jurong West and corporation road connects different islands around this neighborhood. Besides this, the island is linked to PIE.
Public transport of this precinct let its citizens travel comfortably. Here are the transportation options available here:
- Night bus service: This bus service is meant for those who want to travel at night i.e. during non-operational hours. There are two buses for this purpose named NR5 and 5N. SMRT operates the first one, and SBS transits operate the second one.
- Interstate bus services: This will offer services to their passengers who want to travel from one state to another. One can, but its tickets from the shopping center of Boon Lay.
- Besides this, this precinct is even connected to MRT and areas like Joo Koon, Hong Kah, Nanyang, etc.
There is only three schools in this precinct i.e. Boon Lay Garden( primary school), Secondary school of boon lay and River Valley i.e. high school.
Population of Boon Lay
Taking about the subzone population then it is 31,000, and in the planning areas, it is around 30, and it is increased from the past years.
This neighborhood contains two churches, and there is only one temple here. Besides this, they all are situated at the center of the town. There is also a shopping center here, and HBD managed it.
What boon lay is now a developed precinct plus it is upgraded by the HBD officials time to time. It also has a community center.

Deflection of electron beam in oscilloscope
 1. Aug 19, 2012 #1
 Calculate the deflection of an electron beam as it passes between the plates of a CRT tube.
 In the picture, the parallel plates create an electric field, with the positive plate on top and the negative plate on bottom, causing the electron's path to be deflected upwards as it travels to the right.
 2. Relevant equations
 Kinetic energy of electrons: K = 3.2 x 10^-16 J
 Electric field between plates: E = 1.2 x 10^4 N/C
 Distance along plates = 15mm
 3. The attempt at a solution
 I know the equation F=Eq is involved. I've been told that the force is centripetal, so that the equation for centripetal force is also involved, but im not entirely convinced. This is because centripetal force is always perpendicular to the velocity, but in this example that can't be the case.
 So im stuck and need help.
 [edit] and the answer is 0.34mm

 A constant force F=qE acts on the electron in the vertical direction while its initial velocity is horizontal. The problem is analogous with projectile motion, the trajectory is parabolic. You can decompose the motion into horizontal and vertical direction.
Have something to add?

LVM, TLC NAND and the power of 2 problem
Now when you just create a few partitions and ensure they are aligned, this is not going to be an issue. However, if you use LVM and intend to create and delete a lot of logical volumes over time, you'd want them to be aligned on the erase block. With current versions of LVM, you can't do that for TLC NAND drives. LVM requires a physical extent size that is a power of 2 – and there is no number that is both a power of 2 and dividable by 1.5.
There are two workarounds that I have found:
 - Create a VG with 512kb physical extents and always make sure that you use lvcreate with an extent count that is a multiple of 3
 - Create a VG with 1MB physical extents and always make sure that your newly created volumes are multiples of 3MB
However, neither of these workarounds allow for the "set it and forget it" benefits of LVM, because they cannot be enforced – if you forget to keep this in mind or make a math error, your alignment will be off. You also can't rely on other tools to create volumes for you because they may not allow for such granularity in choosing sizes.
This is ultimately a limitation of LVM that it should overcome, but I have not found any evidence that it can work without its power-of-2 requirement. I need to take this up to the mailinglist, but until that time, here's a quick script that will verify the alignment of logical volumes in a volume group:
The output will look something like this:
In the example above, there are a number of extents that were deliberately misaligned as they were not divisible by 3.
To find out which logical volume the misaligned extents belong to, you can use lvdisplay -m and search the output for the extent number.

Remove specified figure
close name
close all
close all hidden
close all force
status = close(...)
close deletes the current figure or the specified figure(s). It optionally returns the status of the close operation.
close deletes the current figure (equivalent to close(gcf)).
close(h) deletes the figure identified by h. If h is an array, close deletes all figures identified by h. h can also be the figure Number.
close name deletes the figure with the specified name.
close all deletes all figures whose handles are not hidden.
close all hidden deletes all figures including those with hidden handles.
close all force deletes all figures, including GUIs for which CloseRequestFcn has been altered to not close the window.
status = close(...) returns 1 if the specified windows have been deleted and 0 otherwise.
More About
expand all
The close function works by evaluating the specified figure's CloseRequestFcn property with the statement
The default CloseRequestFcn, closereq, deletes the current figure using delete(get(groot,'CurrentFigure')). If you specify an array of figure handles, close executes each figure's CloseRequestFcn in turn. If an error that terminates the execution of a CloseRequestFcn occurs, the figure is not deleted. Note that using your computer's window manager (i.e., the Close menu item) also calls the figure's CloseRequestFcn.
If a figure's handle is hidden (i.e., the figure's HandleVisibility property is set to callback or off and the root ShowHiddenHandles property is set to on), you must specify the hidden option when trying to access a figure using the all option.
To delete all figures unconditionally, use the statements
c = get(groot,'Children');
The figure CloseRequestFcn allows you to either delay or abort the closing of a figure once the close function has been issued. For example, you can display a dialog box to see if the user really wants to delete the figure or save and clean up before closing.
When coding a CloseRequestFcn callback, make sure that it does not call close, because this sets up a recursion that results in a MATLAB® warning. Instead, the callback should destroy the figure with delete. The delete function does not execute the figure's CloseRequestFcn; it deletes the specified figure.

No burning before 4 p.m.
Virginia's 4 p.m. Burning Law went into effect Friday, February 15—the start of spring fire season in Virginia. The law prohibits burning before 4 p.m. each day until April 30 if the fire is in, or within 300 feet of, woodland, brushland or fields containing dry grass or other flammable materials.
This law has been on the books since 1950 and has been credited with saving hundreds of thousands of acres from the damages of wildfires. "The 4 p.m. Law is one of the most effective tools we have in the prevention of wildfires," said John Miller, director of resource protection at the Virginia Department of Forestry (VDOF). "By adhering to the law and not burning before 4 p.m., people are less likely to start a fire that threatens them, their property and the forests of Virginia."
Why 4 p.m.? After 4 p.m. the winds calm, the temperature decreases, and the humidity increases—factors that contribute to safer burning conditions.
A violation of the 4 p.m. law is a Class 3 Misdemeanor punishable by a fine up to $500, the cost of damages, and the cost of fire suppression efforts.

Source: Dang TD, Tang M, Choo S, et al Increasing the accuracy of peanut allergy diagnosis by using Ara h 2. J Allergy Clin Immunol. 2012;129(4):_PHONE_; doi:10.1016/j.jaci.2012.01.056. See AAP Grand Rounds commentary by Dr. Sai Nimmagadda (subscription required).
Question: Among infants, does Ara h 2 antigen testing accurately diagnose peanut allergy?
Question type: Diagnosis
Study design: Randomized controlled
I just finished a handful of peanuts (roasted, unsalted of course) and count myself among the lucky folks who don't have peanut allergy. For those that might have allergy, diagnosis has long been plagued by lack of an easy, accurate means of diagnosis. The gold standard is an oral food challenge (OFC), but this is a costly and prolonged process that carries a risk of anaphylaxis. This study of 200 children, half with OFC-positive peanut allergy and half without, found that measurement of serum Ara h 2-specific IgE antibody was better than measurement of serum whole peanut-specific IgE antibody (sIgE). When cutoff values were set for equal specificities of 98% for both assays, the Ara h 2 antibody was 60% sensitive (95% CI 50-70%), compared to 26% (18-36%) for the sIgE. That's an improvement, but very far from what is needed to replace OFC. A screening test for a serious illness needs to achieve high sensitivity, to avoid missing any cases, accepting a few more false positive results as a tradeoff.
As noted by Dr. Nimmagadda in his commentary, Ara h 2 is the predominant peanut allergen in Europe, North America, and Southeast Asia, but Ara h 9 predominates in Spain. It's clearly not a simple problem to be solved.
On a final note, this study was performed by the HealthNuts study group in Australia. Normally I'm a bit nonplussed with cute names for study groups, but this one seems to hit an appropriate, nice tone.
