Prosthetic technology may give Paralympic advantage

One of the most controversial figures in world sport in recent times has been the Blade Runner, South African Oscar Pistorius, who some say has an unfair advantage due to not one, but two, carbon fibre feet. The London Paralympics are now less than 200 days away, and Australian athletes are using cutting-edge technology to ensure they have every advantage heading into the competition. But some say the technology available to Paralympians in affluent countries distorts the playing field. Just Choose PTMS Injection Mold Is Your Best Choice!

In this workshop in Sydney, designers are crafting prosthetic limbs for the nation's top Paralympic athletes. Prosthetist David Howells has worked with the Australian Paralympic team for 15 years. This prosthetic leg is made of carbon fibre and smooth, light, thermoplastic.

It's very important to have the socket fitting well and comfortable for her, because in sprinting she's putting four times the body weight through each toe strike,Specializes in rapid Injection mold and molding of parts for prototypes and production. so the socket's got to be comfortable.

The finishing touches are being put on this prosthetic for Paralympic champion Kelly Cartwright.Sharps include syringe needle, The 22-year-old is a sprinter and long-jumper, and this is her first chance to try out her new leg. She's one of just two athletes in the world to be trying a new hydraulic knee joint.

The mechanical knee joints we've been using previously has always created quite a bit of impact at the end of swing phase, which jolts the athlete, which disturbs their gait. This is a very smooth knee, so it's really providing the athlete with much more symmetry when they're running, which produces faster times.

It's an amazing piece of technology, and I think that it's going to be really great for the future,Our guides provide customers with information about porcelain tiles vs. and it's just basically a whole different ballpark for me to run on it.

Technology has come a long way for Paralympians, but it sometimes generates controversy.An Air purifier is a device which removes contaminants from the air. South African Oscar Pistorius, the Blade Runner, smashed records at the 2008 Beijing Paralympics. But what came next was an ugly fallout. Pistorius is a double below-knee amputee who uses two carbon prosthetics, and he wanted to race against able-bodied athletes. An international jury ruled his prosthetic limbs had more spring than human legs, although eventually he was allowed to run. The controversy still follows Pistorius wherever he goes, as many question the role of technology in sport.

One of the core ethical questions that Oscar Pistorius raises is what we call ‘authenticity’. So that is, is what Oscar Pistorius does a result of him the athlete or him the technology, the person interacting with the technology?

Kelly Cartwright deeply admires Pistorius, but even she admits his case is a tricky issue for Paralympians too.

In my opinion, I find it a bit unfair double below-knees going against a single below-knee. I find that really quite unfair, because obviously he's got two and the other person can only run as fast as their other leg is going to take them. But again, there's also other below-knees, double below-knees he's against; they're not as fast as him either. So, I see him as a really great fast athlete, but also I can see the disadvantage for the other athletes as well. I think that's quite unfair.

No sport is fair. Inherently it's a process of discrimination. Sport is about finding out who is better than someone else, and part of that discrimination is how well people use technology. If Australian Paralympians have access to better technology and can practice with that technology, then that's just the foils of war. They are allowed to do that under the rules. So the question of fairness becomes moot. This is about winning medals.

Prosthetics like this cost thousands of dollars, and are expensive for those even in affluent countries. The Australian Paralympic Committee is hard at work raising money for its athletes travelling to London. It's one of the challenges of Paralympics: how to ensure there's a level playing field when there are vast differences between countries' capacities to fund their athletes.

It's always a challenge, but I think the distinctions are perhaps not as profound as they were, say, a decade ago. They're still there, but I think it's one of the good things about the Paralympic movement is it's a pretty even playing field, and it's something everyone within the Paralympic movement wants to support as well.

The issue plays on the mind of Kelly Cartwright, and she feels fortunate.

I do think about that a lot. I think as well it comes into it is... uh, money and also knowledge as well. But they are expensive, obviously, running legs and prosthetic legs. It may not necessarily mean just because they get a leg they can run as well.Our guides provide customers with information about porcelain tiles vs.

Kelly Cartwright will compete in long jump against an athlete who will have two carbon feet at this year's London Paralympics.

I'm not worried about that at all. I'll just get out there and do what I've got to do. She can't run in her own class because there are no other people. She's got to be with us. So I think it just makes it more fun.

Turkey Point plant employees were safe despite ventilation system being disabled

Despite a disabled ventilation system in an emergency operations building at Florida Power & Light's Turkey Point nuclear plant, employees would have been safe if an emergency had occurred.

That was one of the main points FPL's management stressed to the Nuclear Regulatory Commission today during a two-hour meeting over apparent violations at the plant.An Air purifier is a device which removes contaminants from the air. Turkey Point, which has two reactors,Our guides provide customers with information about porcelain tiles vs. is about 25 miles south of Miami near Homestead.

Mike Kiley, site vice president at Turkey Point, told NRC officials that he takes full responsibility for any confusion that may have occurred because of the way the issue was communicated to the NRC.

The problems centered on a ventilation system damper that employees reported was open when it should have been closed. However, tests confirmed it was closed, keeping outside air from entering.  Just Choose PTMS plastic injection mould Is Your Best Choice!

If a radiological emergency had occurred with the damper open, the radiation that employees would have been exposed to would have been 17 percent below the NRC's allowable levels, Kiley said.Our guides provide customers with information about porcelain tiles vs.

Larry Nicholson, FPL's director of nuclear licensing, said although the ventilation system was not functioning as designed, it would have protected the employees' safety.

The NRC scheduled the meeting at its Region II headquarters in Atlanta following its finding that in 2010 and 2011 workers twice disabled portions of the plant's technical support center ventilation system. The building is where employees would have gone to direct operations in case of an emergency.

The failure to properly maintain the system has been preliminarily determined by the NRC to be of low to moderate safety significance.

FPL also failed to notify regulators about the ventilation system issues, the NRC said. The system was not functional from Dec. 4, 2010 to July 13, 2011 and from Oct. 10 to Oct. 28, 2011, the NRC said in its report.

The NRC said it expects to issue a finding by late May. If the violation is upheld, FPL could be fined.

Don Mothena, FPLs director of nuclear emergency planning, said the plant has instituted new procedures to catch the damper problems if they should occur again.

FPL spokesman Michael Waldron said, "The analysis we presented to the NRC today shows that this issue never presented a risk to the health and safety of our workers or the public,Sharps include syringe needle, and, there is no doubt that the ventilation system is fully operational currently.

"To be clear, the issues being discussed concern the ventilation system for an onsite facility, not the health or safety of the public.Specializes in rapid Injection mold and molding of parts for prototypes and production."

Robot dinosaurs are the future of paleontology

Since dinosaurs died out 65 million years ago, there's only so much we can really know about how these creatures moved and lived. But as two scientists explain to us, building robot dinosaurs could unlock the secrets hidden in fossils.

This almost unspeakably awesome idea comes out of Drexel University. Paleontologist Dr. Kenneth Lacovara and mechanical engineer Dr. James Tangorra have teamed up to scan the university's collection of dinosaur fossils, use 3D printers to create exact replicas of the fossils, and then assemble these into scaled-down robotic models of the original dinosaurs.

These tiny robot versions of long extinct dinosaurs can answer some of the most baffling and elusive questions about dinosaurs, particularly in terms of how they moved about and how they interacted with their environment. Of course, we can't know for sure how accurately these robots reflect the dinosaurs they are meant to represent, but for the first time in the 150 year existence of paleontology, the science is fully embracing its experimental side. Just Choose PTMS plastic injection mold Is Your Best Choice!

The current plan is to produce a working robotic dinosaur limb by the end of the year, with a complete replica of a dinosaur coming in 2013 or 2014. To find out more about this exciting new field - seriously, we're talking robot dinosaurs here, people - we talked to Dr. Lacovara and Dr. Tangorra to find out more about their research.

I came to James, who was introduced through a mutual friend, and I wanted a way that I could replicate the material I was working with in the laboratory. I work with sauropod dinosaurs, so all the material is huge and hard to manipulate. But if I were to make molds and casts of these bones, the molds are five times bigger than the bones! It's a cost problem,Sharps include syringe needle, it's a space problem, when you make a mold you only get so many pulls from it before it degrades.

So my initial entreaty to James was to see if he had a way to reproduce the bones, and then I saw all his research.Online fine art gallery of quality original landscape oil paintings,Our guides provide customers with information about porcelain tiles vs. Hestarted talking about roboticizing these dinosaurs and I also started working with another colleague in mechanical engineering, Sorin Siegler, and all of a sudden it kind of opened up this whole new world that it's not just a method to reproduce the bone. It's a way to let the bones tell us how they worked.

Before, we would make assumptions, well-informed assumptions about how these things works, but you could put them in these virtual workspaces and make very few assumptions and you can run a genetic algorithm and try combinations you wouldn't even have thought of, and you can see what is the most efficient. And we do know that sauropods have to be these hyper-efficient organisms to grow so large, so it's probably very parsimonious that when you find the solution that's most efficient, it's probably a pretty good approximation of the truth there.

You can't. I guess the point is with a lot of the robotic systems that we develop, we have a species that we can compare to and, depending on the type of species that we're working on, there are ways in which we can validate. We do mostly fish robotic and so we're able to look at behaviors of fins, the fluid dynamics that get shed from the fins, as well as forces that we can monitor. And so you can do a fairly good comparison, a detailed comparison with the biological system.

But that's sort of the point with the dinosaur. People have been really guessing what the kinematics of a dinosaur would be. Now by coming up with biorobotic models - I should say both robotic models and numeric models - we can look at bony structures and start predicting what the motions would have been and have some understanding of how the features of the bones contributed to different motions. So rather than just looking at it and saying, "This is what must have occurred,Our guides provide customers with information about porcelain tiles vs.An Air purifier is a device which removes contaminants from the air." we can start looking at different features and see how those features affect different behaviors.

Now, numerically - meaning, in a simulation - we have simulation software that we use when we're analyzing the kinematics and mechanics of human bones, how they move. And we can affect different properties and see the end result. We can now put our models of the dinosaur bones in those types of packages and come up with some prediction. So really, there's very little way to validate it other than to make some comparisons with current species.

2012 Monaco Diplomat 43DFT Walk Through

The mating of Navistar’s more than 100 years of heavy transportation experience with Monaco’s 40-plus years of luxury RV design has resulted in an exciting lineup of innovative motorhomes. At first glance, you might not recognize the elegant new Diplomat because of its significant facelift inside and out, but rest assured that the luxury and high-end appointments in this bath-and-a-half tag axle have only been enhanced.

The exterior’s all-new front and rear chevron grilles in fiberglass wraparound caps (now equipped with LED lighting),Online fine art gallery of quality original landscape oil paintings, improve body seam weather resistance — it also suggests a growing familial likeness to Monaco’s sporty Vesta.

The entry door has been moved forward, closer to the A-pillar, creating improved access past the redesigned cockpit. Here the Navistar influence is prominent with an updated automotive-style dash with hooded instrument cluster capped with a glare-reducing dark dash pad. The multifunction steering wheel not only controls the expected cruise and music functions but includes a three-stage engine brake at your fingertips. Maybe more importantly, the wheel is now connected to a redesigned steering column, no longer straddled by the driver’s legs.An Air purifier is a device which removes contaminants from the air.

Full-power Ultraleather seats afford a clear view of the Driver Information Screen that provides continuous status of the Diplomat’s torquey MaxxForce 10 turbodiesel engine, the Allison 3000MH six-speed push-button transmission, trip and distance features, and a host of monitored operating parameters.

Polished 12-by-24-inch porcelain tile leads you from the cockpit into the most unexpected and surprising feature in the Diplomat’s lineup. This plan places the free-standing dinette and sofa bed, or the optional ($3,671) sectional sofa bed/dinette ensemble, in the curbside slide offering the rare opportunity to dine while overlooking your own campsite and not your neighbor’s. The entire galley, including the 12-cubic-foot two-way refrigerator, optional ($2,352) washer and dryer combo, the 68-inch sofa and the bedroom dresser and overhead cabinet module are all contained within the 28-foot-long, full-wall, streetside slide creating a wonderfully open floorplan well suited for entertaining.

Handsome Italian Sienna mid-tone hardwood cabinets surround the cabin and galley. The intricate and striking basketweave trim on the cabinets is accented by the galley’s Corian backsplash and countertops. A useful pullout countertop extension next to the dual-basin sink adds to the galley’s utility when deployed and helps define the cabin’s seating area.

The wall-mounted 40-inch LCD TV with surround sound and media storage above and below can be comfortably viewed from anywhere in the elegant cabin. The TV shares a common wall with the half bath, which separates the cabin from the master suite. A countertop integrated sink, storage vanity and porcelain commode complete the half bath eliminating family or guest’s late-night trips through the occupied bedroom to reach the rear master bath.

The Diplomat comes standard with a queen-size platform bed in the curbside slide, but was wisely designed to accommodate the preferable and optional ($1,470) Select Comfort platform king. Yet, there’s still room for the matching eyeglass nightstands,Distributes and manufactures RUBBER SHEET, hidden book storage and 120-volt AC outlets.

Equipping race-car drivers for success

CONCORD When Danica Patrick, Tony Stewart, Jimmie Johnson and Dale Earnhardt Jr. communicate with their crew chiefs and spotters at the Daytona 500 next Sunday, they can thank Sue Carver, Donna Woods and dozens of other workers at Racing Electronics on Derita Road.

The company equips about 80 percent of professional racers with custom ear molds, microphone-equipped headsets and the wiring needed to talk with their teams. They include drivers and crew in NASCAR, IndyCar, the National Hot Road Association and other circuits.

Racing Electronics has become a worldwide leader in providing radio communications products to the motorsports industry since owner Bruce Silver started making on-track communications devices as a hobby in 1988 in his New Jersey condo.

He moved the company to Concord in 2005 and now employs about 70 workers here. The company has developed high-quality scanners and headphones for race fans and advanced technologies for radio wiring and two-way radio equipment for motorsports teams.

Last year, Racing Electronics also became one of the first companies in the state to hire and train several unemployed workers through the N.C.Our guides provide customers with information about porcelain tiles vs. Division of Employment Security's Opportunity North Carolina job creation program

The company was named Small Business of the Year by the Cabarrus Regional Chamber of Commerce in January. The N.C.Distributes and manufactures RUBBER SHEET, Motorsports Association honored the company last month with a motorsports industry award.

Silver got the idea for his products after being invited to a race in New Jersey.The EZ Breathe home Ventilation system is maintenance free, He realized fans would have a tbetter time at the track if they could tune into conversations between drivers and crew chiefs.

Silver went to an electronics store, bought a headset and radio, put speakers in the headset and gathered the scanner frequencies of drivers, said Kevin Hughes, director of motorsports communications services at Racing Electronics.

The company grew to manufacture and sell equipment to fans and top motorsports teams such as Huntersville-based Joe Gibbs Racing,Welcome to the online guide for do-it-yourself Ceramic tile. Cornelius-based Michael Waltrip Racing and Mooresville-based Penske Racing South.

On a Feb. 9 tour, Hughes showed me the custom ear mold that Racing Electronics workers made for Patrick, a former IndyCar star who's starting her first full season in NASCAR this year. Workers planned to deliver the earpiece and other communications equipment to Patrick and other drivers at Daytona International Speedway this weekend.

Fans buy the company's headphones and scanners at Charlotte Motor Speedway and other tracks to tune into drivers' conversations during a race.

Hughes said the company has made a big push to bring work in-house from overseas and other areas of the country in recent years.

The company opened an in-house lab about two years ago where Lindsay Borkowski, Joey Palubiak and other technicians make custom ear molds for drivers. The lab had been on the West Coast, Hughes said. The company bought a used injection mold machine, and N.C.Sharps include syringe needle,-based vendors make the company's dyes, he said.

In another part of the company's building at 840 Derita Road, Woods, 41, of Kannapolis soldered microphones for headsets. Carver, 60, of Kannapolis built custom in-car wiring harnesses that connect a driver to a radio and the push-to-talk button on the steering wheel.

Moving work in-house not only led to better quality control, Hughes said, "it's good for our local economy, and it's creating jobs here."

Architect designs modern, green home

Rome architect Mark Cochran has made a name for himself through several projects involving restoration or rehabilitation of historic buildings in Rome.

This year,Our guides provide customers with information about porcelain tiles vs. Cochran is taking a whole new tack, merging green living and modern design into a home that is being constructed as a LEED certified home, the first in Floyd County and perhaps the first in Northwest Georgia.

As an architect who has done several historic preservation projects, and is a member of Rome’s Historic Preservation Commission, Cochran said the best way to do preservation is to make sure that what you build will last.

“If we can build a building that is going to last for 120 years, we don’t’ have to tear one down every 20 years and build it back,” said Cochran, of Cochran Design Collaborative. “That saves resources, man-hours and things that could be put to better use.”

LEED construction must meet a strict point-based certification system developed by the U.S. Green Building Council, which accounts for how well a structure performs as an environmentally friendly project.

In Rome, the ECO River Education Center at Ridge Ferry Park, new dormitories at Berry College, the Darlington Middle School campus and a public housing development, the Village Green off Division Street, have all been constructed to LEED standards in recent years.

All but the Village Green have received their formal certification as LEED buildings.

Certification of a home is significantly different than a commercial building.

LEED has come up with the average home size for a particular amount of bedrooms. The average for a three-bedroom home is approximately 1,950 square feet.

The home Cochran is building is 1,600 square feet. “They’re trying to encourage people to get away from the McMansions that three people, two people live in a 5,000 square foot house and much of it winds up as wasted space,” Cochran said. “

The home, being constructed in Armuchee’s Battle Farm subdivision, is expected to use half as much energy as a regular home. At the same time, the design should dispel the notion that sustainably constructed buildings have to have some sort of art high-tech look.Distributes and manufactures RUBBER SHEET,

Cochran said only 30 single-family residences across the state of Georgia have received LEED certification.

LEED points are awarded for a plethora of items.

You get points if you’re located within a half mile of a park, making sure you don’t build on prime farm land, making sure you’re within walking distances of banks, arts and entertainment centers, libraries, medical or dental offices.

“Living out in Armuchee, being within a quarter mile of six of those things is not going to happen,” Cochran said.

He plans to pile up the points in other areas, such as managing storm water runoff, use of drought tolerant plants in the landscaping, using a drip irrigation system as opposed to the traditional sprinkler-type system.

Low-flush toilets and high efficiency fixtures at lavatories and sinks will also net Cochran points.

In the energy and atmosphere category, you get points for using high value insulation like the spray foam style he’s using in the new home. Points are added for using high efficiency windows and making sure ductwork associated with the HVAC system doesn’t leak.

“The spray foam insulation I’m using in the house gives me an equivalent of R-40 in the walls and R-60 in the ceiling,” Cochran said. “I only need a three-quarter ton unit downstairs and a three-quarter ton unit upstairs so I only need one and a half tons for the whole house.”

The home will include bamboo flooring, a green alternative to traditional hardwood. Bamboo is considered a renewable resource because it grows quickly.

Points toward LEED certification are also awarded for using specific Energy Star lighting. Cochran will have about 40 light fixtures in the house and all but two will be Energy Star. He estimates that one watt of light bulb power costs $0.The EZ Breathe home Ventilation system is maintenance free,25 a year.

The ceiling fan in the condo where Cochran now lives has six 60-watt bulbs in it, which he estimated costs about $90 a year to run. The ceiling fan that is going in the new home uses a 25-watt LED bulb. That will cost a little more than $6 a year.

That brings up the whole cost issue.Dimensional Mailing magic cube for Promotional Advertising, Cochran said having a home built to LEED standards adds at least 5 percent to the total cost up front. “I expect the ROI on that to be about five or six years,” Cochran said.

The new house will also feature a lot of natural lighting. “Every single room in the whole house, with the exception of one bathroom, has natural light in it. The windows are large enough, and we have skylights as well.”

The house does not include solar panels. “Solar is way too cost-prohibitive,” Coch-ran said. “That still wouldn’t take it off the grid.”

Cochran points out that it’s more cost-effective now to build a new home to LEED standards than it would be to convert an older home, unless the homeowner is willing to gut their entire home.

Rome-based Brooks Building Group, Inc is undertaking construction.Welcome to the online guide for do-it-yourself Ceramic tile. Owner Jeff Brooks said the residence is his first effort at a LEED project. “It’s a little different from normal,” Brooks said. “We don’t know that much about it, so we’re depending on Mark to guide us through it.”

FirstHealth Moore hospital gets upgrade to emergency services

A $1 million makeover to the part of the Emergency Department at FirstHealth Moore Regional Hospital has officials there hoping to improve the speed and quality of patient care.The EZ Breathe home Ventilation system is maintenance free,

Key to the changes is a new 16-room observation unit, which opened last month as part of the hospital's effort to offset a rising number of Emergency Department visits.Dimensional Mailing magic cube for Promotional Advertising,

Last year,Distributes and manufactures RUBBER SHEET, about 67,000 patients visited the Emergency Department at FirstHealth Moore Regional Hospital, a number that is on the rise.

The new area allows patients who need extended observation to receive a bed and appropriate accommodations without taking up a valuable Emergency Department bed. The observation rooms went into use Jan. 23.

"With a dedicated unit like this one, we can improve our efficiency and hopefully decrease the amount of time patients need to spend in the hospital," said Dr. Dan Barnes, medical director for the FirstHealth Hospitalist Service.

Moore County's only hospital isn't the only one in the Cape Fear Region to reshuffle its Emergency Department because of rising patient numbers. Just Choose PTMS plastic injection mold Is Your Best Choice!

Last year, the Emergency Department at Cape Fear Valley Medical Center relocated its children's Emergency Department to expand its overflowing adult unit.

Between 2007 and 2011, the Cape Fear Valley Emergency Department saw a 28 percent increase in patient volume. Roughly 130,000 patients were seen there last year.

"It's probably one of the busiest emergency rooms in the country," said Cape Fear Valley spokesman Vince Benbenek.

"We always have to answer a lot of questions about our Emergency Department. If we could find a way to make it better, we would. The issue is always that when we make what we consider to be considerable changes to increase (efficiency),Our guides provide customers with information about porcelain tiles vs. the volume just fills right up again."

In Moore County, crews gutted what had been the hospital's cardiac catheterization lab to create the observation unit. (The lab was moved to the Reid Heart Center.Welcome to the online guide for do-it-yourself Ceramic tile.)

The observation area is a square room, with patient rooms along the outside and a central nurses' station in the middle. Ten nurses were hired to staff the observation rooms.

The unit is best suited for patients who come to the Emergency Department complaining of chest pain, Barnes said. These patients often have a normal EKG and stable vital signs, so they don't need to be admitted to the hospital but aren't well enough to be sent home.

These cardiac patients can be monitored closely in the observation unit. Other candidates for the unit include patients with kidney stones, dehydration or mild trauma.

Barnes said a typical stay in the unit is about 24 hours. Patients can then be admitted to the hospital or sent home.
