Importance of Trail Equipment

Thursday, November 27th, 2008

There are a lot of things you will need if you plan to watch a trail for any reason. It doesn’t matter if you are a hunter or a naturalist, you need to have good equipment if you want to see any results. The good news is that it isn’t hard to find the good stuff. The Internet has opened a number of a new ways to find the best gear from any number of specialty providers.

Let’s start with trail cameras. These are important for anyone who doesn’t want to sit in a tree stand for 8 hours a day. If you want to watch a trail, then you just buy a good trail camera and set it up. Then you just visit it as often as necessary to check on the pictures it is taking. It’s really that simple. Time-lapse photography and motion sensors do wonders. Throw in digital photography and you’re in a good place.

You will also really need to have predator calls if you want something that is a bit tougher. There are sets of predator calls available for just about anything imaginable. You can set your device up to play a raccoon call or a coyote call. If the predator exists, then a good caller will have the option available.

This of course, has to be thanked for because it has credited much to our society and the comfort that we already have in this modern time and era of ours.

Magnetic semiconductor breakthrough may pave way for smaller, faster gadgets

Wednesday, November 26th, 2008

For the first time, researchers at the National Institute of Standards and Technology (NIST) have demonstrated the existence of a key magnetic, and not electronic, property, called antiferromagnetic coupling, of specially built semiconductor devices.

Antiferromagnetic coupling is a property of semiconductor devices in which one layer spontaneously aligns its magnetic pole in the opposite direction as the next magnetic layer.

The discovery of the new property may pave the way for even smaller and faster gadgets that could result from magnetic data storage in a semiconductor material, which could then quickly process the data through built-in logic circuits controlled by electric fields.

Currently, magnetic data storage is successfully utilized in consumer products such as computer hard drives and MP3 players- storage devices based on metallic materials. These conventional hard drives can only hold data; they have to send the data to a semiconductor-based device to process the data, which can slow down performance.

Now, researchers from NIST, Korea University and the University of Notre Dame have supported theories that thin magnetic layers of semiconductor material could exhibit antiferromagnetic coupling.

The discovery of antiferromagnetic coupling in metals was the basis of the 2007 Nobel Prize in Physics.

It was only recently that the property was considered useful in semiconductor materials. Semiconductors with magnetic properties would not only be able to process data, but also store it.

The most widely studied magnetic semiconductor is gallium arsenide (GaAs) with magnetic atoms (manganese) taking the place of some of the gallium atoms. It was predicted that by creating thin films of this material separated by a nonmagnetic material of just the right thickness and electrical properties, one could engineer antiferromagnetic (AF) coupling.

With magnetic fields, one could then switch the magnetization of one of the layers back and forth to create “spintronic” logic circuits, ones that operate not only under the usual control of electric fields but also the influence of magnetic fields (manipulating a property known as spin, which could be imagined as tiny internal bar magnets in particles such as electrons).

The researchers studied these multilayer stacks using a technique known as polarized neutron reflectometry, in which a beam of neutrons is bounced off the stacks.

Since neutrons are magnetic, and are able to easily penetrate through the entire stack, the reflected neutrons provide information about the magnetic properties of the individual layers.

At low temperatures and small magnetic fields, the polarized neutron data unambiguously confirm the existence of an antiparallel magnetic alignment of neighboring layers. When the magnetic field was increased, the neutron data indicated a parallel alignment of all layers.

The results showed that AF coupling is achievable in GaMnAs-based multilayers, a seminal property that now opens up a multitude of device possibilities for this novel material.

As the phenomenon only occurs at very cold temperatures in the material (about 30 K), the researchers believe these results will help inform theorists who could then better understand how to create room-temperature devices with the same magnetic properties.

Too many rich U.S. farmers get subsidies: GAO

Wednesday, November 26th, 2008

Too many rich farmers continue to receive U.S. farm subsidies in spite of income caps designed to restrict their participation, and the Agriculture Department needs to do more to enforce the rules, the auditing arm of Congress said on Tuesday.

More than 2,700 people whose gross income topped $2.5 million — making many of them ineligible for farm programs — received more than $49 million in payments between 2003 and 2006, the Government Accountability Office said in a report.

“If this is true, it is a prime example of the kind of waste I intend to end as president,” President-Elect Barack Obama said in a news conference on Tuesday.

Obama has complained about subsidies to “millionaire farmers” during his campaign, and said he would like a “hard” cap of $250,000.

About 2 million farmers and farm entities receive about $16 billion per year in programs designed to help stabilize incomes when prices fall or to help protect sensitive land.

The farm programs have long been criticized for spurring overproduction and hurting world markets, as well as for giving money to people who don’t need it.

For example, the GAO previously rapped the USDA for paying $1.1 billion between 1999 and 2005 to more than 170,000 people who were no longer alive.

The GAO used tax filer data to see how well the USDA enforced the cap — giving the GAO a “distinct advantage” over the USDA, which lacks the power to access the same data, USDA official Teresa Lasseter said in a letter responding to the GAO report.

A USDA spokesman could not be reached for further comment.

The report recommended the USDA should work with the Internal Revenue System on a new verification system.

“The bottom line is if the department feels it needs more authority to access IRS data, it ought to come to Congress and ask me for more authority,” said Iowa Senator Chuck Grassley, the ranking Republican on the finance committee who asked for the GAO audit.

Grassley told reporters he was most troubled that the GAO found 87 people who received payments despite being flagged in the USDA’s own database as being ineligible.

Other potential infractions included a former insurance company executive who received more than $300,000, an owner of a professional sports team who received $200,000, and a top financial services executive who got $60,000, the GAO said.

The $49 million in potential overpayments is a small percentage of total farm payments, but “that’s a lot of money that can go for school lunch programs for low-income kids, or it could be a bottom-line on the deficit,” Grassley said.

Earlier this year, the new farm bill lowered the cap for farm subsidies, denying all payments to people grossing more than $500,000 and “direct” payments to people with more than $750,000 in farm income.

The GAO said the new caps increase the risk that the USDA would pay people who don’t qualify.

If the new rules had been in place in 2006, it’s likely the USDA would have paid as much as $90 million to 23,500 people who didn’t qualify for payments, the GAO said.

When Yuvi gets going he is the toughest: Dhoni

Wednesday, November 26th, 2008

Indian captain Mahendra Singh Dhoni said he always trusted Yuvraj Singh`s talent as cricketer while noting that the stylish middle over bat also bowled and fielded well when he struck form with the willow.

“Yuvraj is a very talented player. When he gets going he is one of the toughest batsmen to bowl to. He scores in every part of the ground. He is one of the players, when he gets going, he takes you through the series. You always believe that kind of player,” Dhoni said.

He added that when the Punjab batsman gets going his overall form also hits a golden patch.

“When he bats well, his overall cricket goes up. Not only just his batting, his bowling and fielding too goes up. It has been good to see him score loads of runs,” he added.

The captain also said the youngsters need to apply themselves and enjoy cricket without being desperate to be successful at this stage.

“They need to go out there and look to enjoy cricket. If they are too desperate then the chances of them being successful goes down. You should be relaxed, calm and cool.””You have nothing really to prove. At times, I personally feel when you want to perform and do things you end up putting pressure on yourself. So it`s better to be in a positive frame of mind,” he said.

Looking back at the year, Dhoni said they have been performing as a team which was their recipe for success.

“We have individual performers who have done splendidly but as a unit we have done well. When spinners are not in form there were fast bowlers taking wickets and complementing each other. At the same time, batsmen are doing their job. Even the lower order is contributing,” Dhoni said.

“It`s the execution of the plans which is helping. Spinners, seamers, even part-timers are doing well,” he added.

Asked whether he was aiming for a clean sweep which will help the side take the second spot in ICC ODI rankings, Dhoni said, “We are not looking whether to win the series 7-0 or have a 5-2 result. We are not thinking much on that.”

Indirectly taking a dig at the ICC-approved Duckworth and Lewis method to decide a rain-affected match, Dhoni said, “Frankly speaking I don`t understand Duckworth-Lewis. I just wait for the umpire`s decision.”

To some psychiatric patients, life seems like TV

Wednesday, November 26th, 2008

One man showed up at a federal building, asking for release from the reality show he was sure was being made of his life. Another was convinced his every move was secretly being filmed for a TV contest. A third believed everything — the news, his psychiatrists, the drugs they prescribed — was part of a phony, stage-set world with him as the involuntary star, like the 1998 movie “The Truman Show.”

Researchers have begun documenting what they dub the “Truman syndrome,” a delusion afflicting people who are convinced that their lives are secretly playing out on a reality TV show. Scientists say the disorder underscores the influence pop culture can have on mental conditions.

“The question is really: Is this just a new twist on an old paranoid or grandiose delusion … or is there sort of a perfect storm of the culture we’re in, in which fame holds such high value?” said Dr. Joel Gold, a psychiatrist affiliated with New York’s Bellevue Hospital.

Within a two-year period, Gold said he encountered five patients with delusions related to reality TV. Several of them specifically mentioned “The Truman Show.”

Gold and his brother, a psychologist, started presenting their observations at medical schools in 2006. After word spread beyond medical circles this summer, they learned of about 50 more people with similar symptoms. The brothers are now working on a scholarly paper.

Meanwhile, researchers in London described a “Truman syndrome” patient in the British Journal of Psychiatry in August. The 26-year-old postman “had a sense the world was slightly unreal, as if he was the eponymous hero in the film,” the researchers wrote.

The Oscar-nominated movie stars Jim Carrey as Truman Burbank. He leads a merrily uneventful life until he realizes his friends and family are actors, his seaside town is a TV soundstage and every moment of his life has been broadcast.

His struggle to sort out reality and illusion is heartwarming, but researchers say it’s often horrifying for “Truman syndrome” patients.

A few take pride in their imagined celebrity, but many are deeply upset at what feels like an Orwellian invasion of privacy. The man profiled in the British journal was diagnosed with schizophrenia and is unable to work. One of Gold’s patients planned to commit suicide if he couldn’t leave his supposed reality show.

Delusions can be a symptom of various psychiatric illnesses, as well as neurological conditions such as Parkinson’s and Alzheimer’s diseases. Some drugs also can make people delusional.

It’s not unusual for psychiatrists to see delusional patients who believe their relatives have been replaced by impostors or who think figures in their lives are taking on multiple disguises.

But “Truman” delusions are more sweeping, involving not just some associates but society at large, Gold said.

Delusions tend to be classified by broad categories, such as the belief that one is being persecuted, but research has shown culture and technology can also affect them. Several recent studies have chronicled delusions entwined with the Internet such as a patient in Austria who believed she had become a walking webcam.

Reality television may help such patients convince themselves their experiences are plausible, according to the Austrian woman’s psychiatrists, writing in the journal Psychopathology in 2004.

Ian Gold, a philosophy and psychology professor at McGill University in Montreal who has researched the matter with his brother, suggests reality TV and the Web, with their ability to make strangers into intimates, may compound psychological pressure on people who have underlying problems dealing with others.

That’s not to say reality shows make healthy people delusional, “but, at the very least, it seems possible to me that people who would become ill are becoming ill quicker or in a different way,” Ian Gold said.

Other researchers aren’t convinced, but still find the “Truman syndrome” an interesting example of the connection between culture and mental health.

Vaughan Bell, a psychologist who has researched Internet-related delusions, said one of his own former patients believed he was in the virtual-reality universe portrayed in the 1999 blockbuster “The Matrix.”

“I don’t think that popular culture causes delusions,” said Bell, who is affiliated with King’s College London and the Universidad de Antioquia in Medellin, Colombia. “But I do think that it is only possible to fully understand delusions and psychosis in light of our wider culture.”

Polymers ‘battered’ with nanoparticles may pave way for self-healing paints

Tuesday, November 25th, 2008

University of Warwick researchers say that they have developed a process whereby small particles of polymer can be easily and cheaply covered with a silica-based nanoparticles.

Lead researcher Stefan Bon, a chemist at the university, said that the final result from the new process would come in the shape of a highly versatile material that could be used to create a range of high performance materials-such as self healing paints, and clever packaging that can be tailored to let precise levels of water, air or both pass in a particular direction.

He describes this process as a “soap free emulsion polymerization process” that makes colloid particles of polymer dispersed in water, and in one simple step introduces nanometre sized silica based particles to the mix.

The silica-based nanoparticles, about 25 nanometre in size, then coats the polymer colloids with a layer “battering” it almost like a fish can be battered in bread crumbs.

Bon has revealed that the process results in the creation of a very versatile polymer latex product, which can be used to create scratch resistant paints in which the scratches heal themselves.

He says that the material can even be fine tuned to produce polymer-based packaging, which will allow water or air to pass through the packaging in tailored ways.

The resultant rough textured spherical shapes also lend themselves to the creation of sheets with polymer that present much more surface area than usual allowing more efficient interaction with other materials.

When the researchers exposed the material to a second simple step that deposited another polymer layer on top of the already silica based nanoparticles “battered” polymers, they were able to produce particles with an even greater range of properties and uses.

The team believe that industrialists will be interested not just in the versatility of the end product, but also in the ease and cost effectiveness of the process because it dramatically reduces the time needed to create materials that are currently used in industrial equipment.

James Bond computer technology may soon replace mouse with interactive gloves

Tuesday, November 25th, 2008

The computer technology shown in science fictions like Minority Report and James Bond flicks are drawing closer to reality, with a Los Angeles-based company designing a system that can consign the mouse to history.

John Underkoffler, chief scientist at Oblong Industries that has created the technology, says that the new technology called G-Speak may fundamentally change the way we interact with computers.

He says that rather than having to use one hand to control a mouse, a user can communicate with a PC intuitively by “slipping on special gloves” and “using both hands”.

“Human hands are the most sophisticated manipulating tools in the world,” Times Online quoted him as saying.

“The idea is to drop the mouse and let hands do what they’re fully capable of. That is to describe and push, poke and pull and manipulate the world,” he added.

G-Speak allows selection of objects on screen through pointing. When the user brings his hands closer to his body, the object seems to have come closer and appears larger. Pushing the hands to one side moves the object to a different screen.

Underkoffler reveals that things on screen are interacted with as if they were real.

Though some companies and universities are already using the technology, Oblong plans to develop it to be suitable for an elite police force

“It’s exactly like the interface from Minority Report, except that it’s better, because its in the real world and it works,” said Underkoffler.

The technology involves multiple screens allowing several people to control what they see at once, and can take up entire rooms. However, Oblong is working on smaller versions so that they can be used in the home and at work-stations.

G-Speak would run on the existing personal computers, and the company has plans to sell the technology for not much more than the cost of a high-quality mouse, that is 20-40 pounds.

Oblong believes that the technology will be available in the market in about two years.

Given that the system is very intuitive, UnderKoffler believes that it will replace the mouse.

“If you’ve had the experience of trying to teach your great uncle how to use a mouse, it’s frustrating. Most people who put on the gloves are up and running within 30 seconds, because everyone knows how to point,” he said.

The technology is being experimented with for uses such as air-traffic control or medical imaging, which could help surgeons.

“The idea is to invert the usual way of working. The ordinary way of working that we are still tethered to is that the human must go into the machine’s world. You have to imagine yourself in the cartoon world of the desktop, and put yourself down there. We want to break open the monitor, and let the pixels go everywhere in the room - to put the interaction with the computer in the real world,” Underkoffler said.

Hope for the best in 2009-10: Dr. Kurian

Tuesday, November 25th, 2008

Dun & Bradstreet, the world’s leading provider of global business information, knowledge and insight along with Deutsche Bank organized a panel discussion onDistribution – Challenges under the current market conditions.

Distribution of financial products is a challenge in today’s market with the entry of new players, rising competition and saturation of the urban markets. Companies are now targeting tier-II cities and identifying innovative distribution channels to widen the market base.

Intermediaries are also playing an important role in taking distribution of financial products to cities beyond the first twenty. The panel discussion focused on the above mentioned issues and provided perspectives on how to make the financial products available to a larger market, especially under the present market conditions.

Delivering the welcome address, Dr. Manoj Vaish, President & CEO – India, Dun & Bradstreet said, “India’s economy is expected to maintain its growth momentum, however, given the current global scenario, we can see some slowdown in growth for the time being. But we feel this situation won’t sustain for long, India’s position in the global financial markets will become more prominent and stronger.

A rise in beneficial investment planning would ensure long-term sustainability of economic growth and will also create incremental economic opportunities”

Speaking on Distribution-what more does the market need?, Mr. A.P Kurian Chairman Association of Mutual Funds of India said , “Financial products act as an investment avenue and provide the required financial security to the investors based on the risk return profile of the financial products.

In this context, Mutual funds is the fastest growing investment segment in the country. There has been a prominent growth of about 20-60% in the mutual funds segment in the last few years. But, nevertheless, though there has been a dramatic fall in the segment last October, the economic condition is expected to bounce back to normalcy by 2009-10 sustaining the safety of investing in mutual funds for a long term benefit”.

Highlighting on the current global turmoil, Mr. C.Jayaram, Executive Director, Kotak Mahindra Bank quoted, “it is important to form a regulatory body to monitor the distributors keeping in mind the significance of asset allocation for investments”.

Likewise, Mr. Indrajit Gupta, Managing Director, Peerless Securities Ltd opined that keeping in mind that the economic condition will tilt towards the positive side of growth in a couple of years, it is the right time for investments for gains in the long run.
