For 25 years, Tekna continues to be developing and commercializing both equipment and processes according to its induction plasma proprietary technology. Our induction plasma technology is especially well adapted to the production of advanced materials and also the powders needed for new innovative emerging products and manufacturing technologies.

Tekna supplies full-scale productions of a number of Nano powders and micron-sized spherical powders meeting all the requirements of the more demanding industries. Boron Nitride Nanotubes (BNNT) represent the brand new group of materials at Tekna.

AC: Can you summarize to the readers the details in the press release you published earlier this season (May 2015) which announced collaboration using the National Research Council of Canada (NRC)?

JP: The National Research Council of Canada (NRC) developed, on a Tekna plasma system, a procedure to make boron nitride powder). BNNTs certainly are a material with the potential to produce a big turning point in the marketplace. Since last spring, Tekna has been around in a unique 20-year agreement using the NRC allowing the firm to manufacture Boron Nitride Nanotubes at full-scale production.

BNNTs are an extraordinary material with unique properties that can revolutionise engineered materials across a wide range of applications including from the defence and security, aerospace, biomedical and automotive sectors. BNNTs have got a structure very similar to the more effective known carbon nanotubes. They share the extraordinary mechanical properties of Carbon Nanotubes but have several different advantages.

AC: How does the structure and properties of BNNTs change from Carbon Nanotubes (CNTs)?

JP: The dwelling of Ni-Ti Powder is really a close analog in the Carbon Nanotubes (CNT). Both CNTs and BNNTs are viewed since the strongest light-weight nanomaterials and they are excellent thermal conductors.

Although, in comparison with CNTs, BNNTs have a greater thermal stability, an improved resistance to oxidation and a wider band gap (~5.5 eV). This makes them the very best candidate for most fields in which CNTs are presently used for insufficient a better alternative. I expect BNNTs for use in transparent bulk composites, high-temperature materials (including metal matrix composites) and radiation shielding.

Comparison between the main properties of BNNTs and CNTs (Source: NRC)

AC: What are the main application areas where BNNTs can be used?

JP: The applications involving BNNTs continue to be in their beginning, essentially as a result of limited accessibility to this material until 2015. Using the arrival in the marketplace of large supplies of BNNT from Tekna, the scientific community will be able to undertake more in-depth studies of the unique properties of BNNTs which will accelerate the introduction of new applications.

Many applications can be envisioned for Tekna’s BNNT powder as it is a multifunctional and quality material. I can tell you that, currently, the mixture of high stiffness and high transparency has been exploited in the introduction of BNNT-reinforced glass composites.

Also, the top stiffness of BNNT, along with its excellent chemical stability, will make this product an excellent reinforcement in polymers, ceramics and metals.

Besides, many applications where heat dissipation is critical are desperately looking for materials with a good thermal conductivity. Tekna’s BNNTs are the most useful allies to further improve not simply the thermal conductivity and also maintaining a definite colour, if required, because of their high transparency.

Other intrinsic properties of BNNTs will probably promote interest to the integration of BNNTs into new applications. BNNTs have a great radiation shielding ability, a very high electrical resistance along with an excellent piezoelectricity.

AC: How can Tekna’s BNNT synthesis process differ from methods employed by other businesses?

JP: BNNTs were first synthesized in 1995. Since that time, a few other processes happen to be explored for example the arc-jet plasma method, ball milling-annealing, laser ablation pyrolysis and chemical vapour deposition.

Unfortunately, these processes share an important limitation: their low yield. Such methods lead to a low BNNT production which happens to be typically under 1 gram per hour. This fault might be coupled with the lack of ability to make small diameters.

As a result, the availability of large quantities of high quality BNNTs for applications development using these processes is still a significant challenge.

Fortunately, Tekna’s inductively coupled plasma (ICP) technology has successfully overcome this challenge. The combination of Tekna’s ICP expertise and its partnership with the NRC opened the door to a brand new range of systems capable of producing highly pure BNNTs in significant quantities. Tekna’s system productivity reaches up to 2 orders of magnitude higher than any of the current methods.

AC: What are the advantages of using Tekna’s unique approach in terms of quantity and price for the commercial market?

JP: The productivity and cost efficiency of Tekna’s ICP technology allow for the first time, the supply of kilograms of Boron Nitride Nanotubes, produced at a much lower production cost.

AC: Could you outline the composition of the BNNTs Tekna synthesizes?

JP: The main interesting characteristics include the tube diameter, about 5 nm, and purity (> 50 %). Most nanotubes contain 3 to 5 walls and are assembled in bundles of some Silicon nitride sintered powder.

AC: How will you begin to see the BNNT industry progressing on the next five-years?

JP: As large amounts are now available, we saw the launch of several R&D programs based on Tekna’s BNNT, so when better quantities will probably be reached over the following five years, we can easily only imagine precisely what the impact could be in the sciences and industry fields.

AC: Where can our readers learn more specifics of Tekna plus your BNNTs?

JP: You can find details about Tekna and BNNT on Tekna’s website as well as on our BNNT-dedicated page.

Jérôme Pollak was born in Grenoble, France in 1979. He received the B.Sc. degree in physics through the Université Joseph Fourier, Grenoble. He transferred to Québec (Canada) in 2002 to get results for the corporation Air Liquide in the appearance of plasma sources for the detoxification of greenhouse gases.

He continued his studies in Montreal, where he received an M.Sc. and after that a Ph.D. degree in plasma physics from your Université de Montréal in 2008. His M.Sc. thesis was 21dexqpky the look and modelling of field applicators to sustain plasma with RF and microwave fields.

I actually have been teaching Pre-School for the past twenty years. The question I frequently get asked by parents is, “teach your child to read in 100 easy lessons app The notion is not difficult: Consistency, Repetition and Imitation. It doesn’t matter What you will be teaching your son or daughter-it can be telling time, it may be tying a shoe; it may be riding a bicycle. It is essential to remember is you must reinforce any concept every day.

Each morning I sit my students upon a huge area rug so we do a 10 minute circle time. My circle time includes: The Alphabet Song, Counting to 20, Months of year, Days each week, Colors and Shapes. In addition, i throw in, “What year will it be?” and initiate with Two thousand and… A youngster always yells out “14!” My next question for you is “What month is it?” I start sounding out of the name from the month which happens to be displayed brightly on our calendar. It can be currently September so I would start with sounding out your word. Using this method daily my students can recite this to me and so they can recite this to their parents as well as to someone else who is ready to listen!

Exactly what does all of this mean?

Consistent-

To be consistent means that you must practice an idea each day.

Repetition-

Repetition ensures that in order to find out the Alphabet song, then you should sing the Alphabet song again and again daily.

Imitation-

Parents should model good reading habits even when it is simply by reading a newspaper or perhaps a magazine daily. Should you read daily, your child would like to read daily.

Kids are learning from the moment they are born and absorb whatever we teach them. Introducing “reading” to your young child can be carried out simply by reading on a daily basis. Make it the daily routine. It could be after school, or it may be before bed. Whatever you decide will end up an expected daily event. Read a loud in your child and follow each word together with your finger. Reading a loud to children enables you to broaden their vocabulary and develop their expertise in different dexqpky62 of print. Eventually a young child will learn that print is hooked on phonics best reviews from left to right and from the top of the the page on the bottom. They may discover how to correlate the spoken words using the printed words.

1. Read 15 to twenty or so minutes daily.

2. Keep many different books on hand.

3. Discuss the story as you may read.

4. Read out loud using funny voices and act the storyline out. (This keeps a child’s attention.)

5. Point out the language as you read.

6. Create flash cards that will help identify letters. For those who have mastered letter recognition then create flash cards that teach letter sounds. If it is mastered then start sounding out or decoding words.

(Helpful Hint: Learn 3 letters or letter sounds at a time, once that is mastered add two more, when those 3 are mastered, add two more, until all 26 letters or letter sounds are completed or known)

7. Read everything! Street signs, Store Signs, Menu’s, Billboards, etc.

Please keep in mind the sooner within a child’s life you commence to http://www.children-learning-reading-review.com, the better your youngster will probably be. Allow it to be fun, make it engaging, and ultimately come up with a solid foundation that begins your child’s educational journey.

Ahead of getting a HIV home test you should take the time to relax. Like many people who get tested the very first time you may be fearful and anxious. Remember that you are currently not negative or positive until an evaluation is performed for you. It will, therefore, make a difference to stay strong and positive. Human Immunodeficiency Virus usually attacks the immunity process from the victims. HIV then weakens the device until it is not able to fight back diseases.

When the Human Immunodeficiency Virus infection enters its final stage, AIDS, the victim’s body will not likely fight life-threatening conditions any longer. For that reason everybody who think they might have been exposed to the virus should at the very least do hiv test thailand. While there is no permanent remedy for HIV victims, they may live longer and healthier lives through the help of medicines.

Something you have to know is the fact this virus can be found only within the body fluids of an infected person. Body fluids can include breast milk, saliva, anal fluids, vaginal discharge, blood and semen. Urine and sweat cannot hide this fragile germ. Not surprising even the most basic HIV home test currently available will detect HIV in saliva and blood.

The top source of HIV and AIDS all over the world is irresponsible intercourse. When someone does either vaginal or anal intercourse without a condom, they may catch HIV or other Sexually Transmitted Infections (STIs). This can include men that have anal intercourse with other men. Besides sexual contact, the HIV may be transmitted via contaminated injecting tools, such as needles.

Syringes can at the same time hold the bug. Drug abusers and those who use steroids while sharing injecting equipment could easily transmit the virus. Each woman who are suspecting pregnancy today must do a HIV home test. By so doing they will likely know their status and if infected they may protect the innocent fetus from getting dexqpky54 too. Mother to baby infection occurs through breast milk or during delivery. Although the danger of contracting HIV through oral intercourse or shared toys for intimacy is substantially low, it is still there.

The fastest and the majority of confidential way to learn your status is by a HIV home test. You can find over-the-counter testing kits throughout world currently. Sometimes you can get PEP or post-exposure prophylaxis. This is an emergency anti-HIV medication that may be made available to individuals who have recently enter into experience of the germs. It ought to be taken within three days of suspected risk event. Like many people you most likely usually do not want to check out a local clinic to become tested. Someone like you can find the Over-the-counter HIV home test kit.

If you are looking to buy a present for a true basketball fan, then official NBA jerseys are the ideal solution. Basketball fans supports their favorite team on or off the court with authentic NBA jerseys, basketball jerseys sydney or even the popular Swingman jerseys. Most of these jerseys are made of good quality fabric and made with the team name, official team brand name and your best player’s number featured around the front and back, the same as those who the NBA stars wear about the court. The real difference between the two is quality, cut, trim and cost. According to your finances you are able to determine which is most beneficial the hoops fan in your own life.

Most basketball fans are true inside their support and would like to wear the real thing, however this may not be practical for all. Because authentic jerseys are like the genuine ones worn on the court, they can often be too large for the majority of fans. Authentic jerseys are cut with the same trim, fabric and application since the pros and although various sizes can be purchased, they will still fit for function and gratification. As they are created to withstand intense damage, they are a lot more durable. This really is ideal when you only want the very best, however, if a fan is keen on showing support, an NBA replica jersey could be a better option. Replica jerseys provide you with the same styling because the authentic jerseys, but have screen printed lettering made of a lighter mesh material, causing them to be cheaper and a bit more comfortable. An alternative choice to your NBA fan will be the Swingman jerseys. These jerseys are favorites among fans as they are cheaper than the authentic, yet carry many of the same qualities. The most significant distinction between the Swingman jersey along with the authentic jersey is the material as well as the lettering. The Swingman jersey features screenprinted tackle twill lettering.

If you’re searching for women or kids, you’ll want to adhere to the replica jerseys or perhaps select jerseys made specifically for youth and women’s sizes. The fabric applied to nba jerseys melbourne is softer and much more comfortable. Irrespective of the jersey that is perfect for your fan, all official NBA jerseys carry the official NBA and team logos.

You will discover jerseys at several places, you may shop at apparel stores or you can take your shopping on the web. I’m a huge proponent of internet shopping for most reasons, but beyond selection and availability, pricing is the greatest benefit from shopping online. You do must make sure the retailer is reputable and carries only authentic products. While it’s not fool proof, you may get a very good idea of the quantity of service based upon customer testimonials and reviews. Another symbol of quality services are the simplicity of transaction and the accessibility of live support or telephone support. Getting into business for an extended length of time doesn’t’ always signify the service could be the best, but it is definitely an excellent indicator.

With competition still fierce within the jobs market, a lot of people may be lured to beef up their resume by buy a diploma.

The trouble of fake degrees is certainly not new, nevertheless the Internet has created it easier than ever to have a bogus qualification.

George Gollin, a board part of the Usa-based Council for Advanced Schooling Accreditation, told CNN he estimates more than 100,000 fake degrees can be bought each and every year inside the United states alone. Of people, around 1 / 3rd are postgraduate degrees. He added that the bogus degree will typically cost $1,000.

By trade, Gollin is a physics professor at the University of Illinois. He first became interested in degree mills after being spammed with offers of fake college degrees.

In accordance with a narrative in Wired Magazine, his interest considered outrage after he discovered news of any forensic psychologist who had purchased her degree. “Here’s he or she who’s untrained doing therapeutic interventions,” he told Wired. “I assumed, ‘Jesus, this is actually bad.'”

The institutions that sell these fake qualifications are known as either diploma mills or degree mills. Diploma mills issue fraudulent diplomas supposedly granted by real universities, while degree mills pose as real universities.

In accordance with Gollin, establishing a degree mill is just a case of creating a website seems as if it belongs to an actual university. The Net site contains a way for customers to fund their qualifications on the web and a spot for prospective employers get in touch with to confirm the degree is genuine.

Some extent mills award degrees according to the buyer’s supposed “life experience,” while some require a small amount of coursework. One degree mill required regarding a week’s worth of coursework to earn a masters degree.

Gollin said this token coursework is largely for your customers’ benefit — to assist them to convince themselves they have got earned their qualification.

While some people could be duped into believing they are getting a legitimate qualification, Gollin stated that just about everyone buying from a degree mill knows these are obtaining a fake.

“Anyone who’s had any contact with an actual college curriculum knows how hard you must work,” Gollin told CNN. “If you may get a whole PhD over the course of one week and you don’t know that’s not legitimate, then you’re just dumb.”

But also for some, knowingly buying a fake degree is a straightforward way of improving their job prospects.

“Generally, fake degrees are often bought for economic advantage for individuals that are looking for promotion or seeking to get jobs where employer wants them to possess a degree,” Gollin told CNN.

Those people result from all avenues of life. Gollin gave the instance of one American who purchased a Bachelor’s degree in nuclear engineering, and who’s now working in the control room of the nuclear power plant.

He also cited a United states degree mill that sells fake PhDs to real medical doctors for $ten thousand, and added that unqualified doctors are already jailed inside the U.S. after attempting to practice medicine by using a medical degree bought online.

In accordance with the story in Wired, Gollin was instrumental inside the case brought against a qualification mill which operated various bogus universities, including Saint Regis University.

The “Saint Regis” degree mill was estimated to obtain made $7 million from selling fake qualifications to more than some 9,600 customers in 131 countries, according to Wired.

In 2008, the pair behind the Saint Regis degree mill were each jailed for three years.

From the Usa, and also other countries, it really is illegal to issue what purports as a university degree without having the approval of a government agency. But degree mills are often set up in such a manner that makes it hard to track down the people running the operation.

Gollin warned that degree mills have become increasingly sophisticated, often carrying official-seeming accreditation that creates them look like genuine universities. The dexqpky12 is the accreditation is supplied by bogus organizations — “accreditation mills.”

If it’s hard for the authorities to keep tabs in the degree mills, it may be even tougher for employers to spot in case a potential employee has fake qualifications, but Gollin said you can find steps that employers can take to guard against fraudsters.

Many countries have government-run websites where you could easily check if a university is officially accredited. But because diploma mills offer buy diploma certificate from real universities, it is essential that employers also talk with someone on the university that this degree was actually issued.

When someone claims with an advanced degree that they ought to have written a thesis, they should certainly generate a copy of that particular thesis. Once they can’t provide information for graduate studies advisor, be suspicious.

But separating the actual through the fake becomes more complicated if a job candidate carries a qualification obtained overseas.

Not only can it be difficult to verify which a foreign university is genuine, Gollin said there were cases of professors at real universities in West Africa selling degrees in the side. He added that some legitimate U.S. universities are unwittingly partnering with degree mills that operate abroad.

Gollin said, “This really is a very sophisticated problem and I think it is going to continue to be a concern as international education gets to be more significant.”

Corrugated stainless tubing utilized for gas piping: manufacturers, sources, installation specifications & building codes. Field report of CSST gas leak. CSST gas piping protection measures.

This short article describes CSST: carbon steel oval tube tubing used for gas piping in buildings. Since 1990 CSST has been utilized within many buildings both in exposed and enclosed areas to install new gas system piping. This content discusses CSST uses, sources, installation specifications, and security measures to protect the gas piping from damage by abrasion, puncture, lightning strikes or another hazards. Gas piping codes and industry types of CSST are included.

Our page top photo, provided courtesy of Carson Dunlop Associates, a Toronto home inspection & education firm, illustrates an improper installing of standard yellow CSST gas piping – routed in ground contact inside a wet area. Yellow “Standard” CSST gas pipin galso requires special electrical ground bonding to reduce risk of damage & leaks in parts of high lightning strike activity.

Newer black or dark-jacketed CSST gas piping (shown below, adapted from GasTite’s FlashShield CSST sales literature) currently sold by most manufacturers may well not require special bonding.

Black CSST gas piping, adapted from GasTite’s FlashShield sales literature cited in this article.

Watch out: Let’s avoid a reason for confusion: CSST used as gas piping runs in buildings is not the identical product since the flexible gas connector tubing (shown below) employed to actually connect gas appliances to the gas supply system, as well as other installation and product protection measures are needed. CSST gas piping is used to route gas or LP gas supply by way of a building even though the flexible gas tubing shown below is specifically designed to the connection of gas appliances on the gas piping system.

Seek out corrugated stainless steel tubing (CSST) used as gas piping in buildings constructed in the Usa or Canada after 1990 plus search for it in older buildings where gas piping was newly installed or modified since 1990. CSST is additionally placed in other countries.

Collapsing building © Daniel FriedmanStandard “yellow” or newer black CSST might be recognized in (usually) long runs between the building gas source and its particular point of use at gas appliances. The gas appliance connector itself (shown in the photo just above) might be connected directly in between the end from the CSST as well as the appliance, or maybe the CSST may terminate or even be together with black iron gas piping within the same building.

CSST gas piping is run both in exposed locations and thru building cavities for example walls, ceilings or floors.

The number of homes have CSST installed? We had trouble relating industry estimates along with us Census data and U.S. Energy Information Agency data, but there is no doubt how the piping is installed in many homes in Canada, the usa, and Japan.

According to the CSST Safety Website (below), corrugated stainless-steel tubing is set up in about 500,000 new homes each year. As being the U.S. Census Bureau and United states HUD February 2015 New Construction Data news release reports a seasonally adjusted annual rate of the latest construction in the United states of around a million homes, that demonstrates that 50 % of brand-new homes are being built with CSST gas piping.

Or maybe we look at the February housing start data this means that almost 100% newest homes use CSST gas piping – which sounds a bit dubious. In 2014 the U.S. EIA reported that 27% of all the U.S. homes were supplied with natural gas and less than 1% along with other gases.

I’m a dwelling contractor in Wisconsin, I would like more details on elliptical tube useful for gas piping in buildings. It appears as though manufacturers don’t require that it is secured or strapped significantly in any way. ‘m not sure exactly what the codes say concerning this. I’ve seen it snaked just about everywhere without support — and what follows is a story of one consequence (quoting from an e-mail to some manufacturer):

I wonder when you could supply a concept about support and protection requirements for CSST. I simply came back from helping my Brother-in-Law by incorporating issues in the Condo in Boston — he had a sprinkler pop across the winter, so the vast majority of drywall needed to be removed to dry things out. Once the restoration contractor removed one section of drywall, the aroma of gas poured out. CSST was snaked through floor trusses and had looped up in one location, when a pneumatic nail in the hardwood flooring installation had punctured it.

Presumably, it has leaked because the building was constructed (a decade ago), and been a hazard the whole time. Any “gas” smell people could have noticed was probably masked with the aroma of the garage, since the leak is in the ceiling higher than the garage.

Reading a number of manufacturers’ installation guides, there doesn’t seem to be a requirement to SECURE the gas line in any way — it merely needs to be supported every 8′ or so horizontally, right? Within my Brother-in-Law’s condo, the gas line was snaked all over and not really strapped anywhere, although it was protected by nail plates at stud and joist penetrations. Could this be acceptable, based on your guidelines and then any applicable codes?

I ask, because checking this out can be covered with insurance, if it’s seen as a hazard or otherwise up to code or manufacturer’s specifications. Thanks, J.

The manufacturer’s reply was essentially how the CSST must be kept 3″ clear of finished surfaces or protected by nail plates if also within 5″ of some constraint (like a penetration using a framing member). Beyond that, it offers an “escape” for nail penetrations. This failed to avoid the leak I described, because the dexopky14 looped up and was hit by way of a pneumatically-driven flooring nail… CSST may seem like a great thing — simple to install, etc. I wonder in the event you would do an article upon it?

The background and field experience with CSST utilize in The United States resulted in concerns about possible pitting, corrosion or perforation of the original yellow CSST gas piping in places that lightning strikes were common. Kraft and Torbin (2007) explained that arcing between poorly-grounded CSST gas piping as well as other nearby metal pathways develop a potential which may encourage electrical arcing damage to the CSST gas lines. Such lightning-related electrical arcing can weaken or perhaps perforate the gas piping leading to dangerous gas leaks.

The chance of arcing injury to CSST is increased in areas where lightning activity is greatest and the location where the CSST will not be well bonded to some grounding system.

The authors demonstrated that lightning-related electrical arcing damage risk to CSST could be reduced by direct-bonding of your gas piping system towards the building’s electrical ground system: the level of the electrical charge from an indirect lightning strike was reduced (in their study) from 97% of your charge as a result of 20% by direct electrical bonding to the building’s electrical ground system. Their 2007 report concluded with a recommendation for direct ground bonding of CSST as a proposal towards the National Fuel Gas Code. During 2009 the same authors reported that CSST could perform acceptably but made important and detailed ideas for the soil bonding of CSST gas piping systems.

Goodson inside a patent application (2009) also reported on the effectiveness of direct bonding of both yellow and black CSST gas piping to lower the danger of damage from indirect lightning flashing. Goodson explained that CSST was generally not really a good electrical ground, thus lending importance towards the “direct bonding” discussion just for this gas piping system. Stringfellow (2013) continued to report on electrically-induced gas distribution piping.

Currently (2015) the makers have just about switched to an improved, more durable CSST gas piping whose design incorporates a protective outer jacket and for which extra manufacturer-specified ground bonding is not required. I feel that only Ward consistently make the yellow CSST easily obtainable in the Usa

In accordance with Jim Narva, executive director of the National Association of State Fire Marshals, that association is centering on informing homeowners of the necessity for retrofit ground bonding of older CSST installations.

OPINION: I agree that CSST must be shielded from damage, including or possibly specifically after it is run through building cavities where, hidden from view, it’s otherwise too easier for a future building occupant or worker to shoot a nail or screw from the material. One could feel that excluding concerns for corrosion, similar worries pertain to (and customarily prohibit the use of) flexible copper tubing when used for gas piping: it is far from routed within building cavities. Instead in those situations it’s present with use steel piping for such gas lines.

In the CSST installation example specifications listed here you’ll see that the makers typically require a variety of installation details to assure safe reliable operation in the gas piping system, including nail plates, flexible corrugated steel armor in certain locations, support, and also other measures. Some local jurisdictions further detail CSST gas piping installation specifications like where and how it could be routed.

Below at left is a good example of a regular steel gas pipe routed through a wall cavity during building renovations of your New York City Home. As well as at below right you will see the traditional change from flexible copper tubing to CSST tube as soon as the gas piping system was required to penetrate the building wall.
