Portable Gps Device Guide

Getting lost is harder now that drivers can count on portable GPS devices to give them directions to new or unfamiliar destinations.

Prices on these global positioning system devices have dropped and are much more affordable to the average driver yet there are more and better features on these newer GPS receivers.
Here are some of the main features and functions available on portable vehicle GPS navigators.


Unlike the more expensive factory installed versions found in some vehicles, a portable GPS device can be removed from one vehicle and used in another. Power comes from an internal battery or the 12 volt outlet in a vehicle's interior.

Addresses or names of locations are entered on a touch screen which displays 3D maps that change as the vehicle heads toward its destination. Depending on the brand or model, maps for the United States, Canada and Europe are available. Satellites keep track of where the vehicle is at all times.

Some portable GPS devices give spoken turn-by-turn directions. Drivers can set the spoken directions to include street or road names. They can also chose between either hearing a male or female voice. A few brands or models can also translate to different languages.

When a route is selected by the GPS but the driver misses the turn or exit, the GPS will return directions to get the driver back on course. In urban areas, some GPS receivers will provide alternative routes if there is traffic congestion up ahead. The driver still has the choice of ignoring the suggestion and continuing on the same original route. Other GPS devices can show routes that avoid toll booths.

Portable GPS devices that are Bluetooth compatible can allow hands-free operation if the driver supplies a Bluetooth enabled cell phone. Drivers can give a voice command to the GPS for it to find a point of interest such as a restaurant and call to make a reservation.

Although a portable GPS receiver can do many things a traditional paper map can never do, it will not replace driver experience or common sense. GPS devices usually give accurate routes, but in a small handful of situations such as on hilly terrain, turn directions are sometimes questionable.

If you don't drive often to new places, then a portable GPS may not be necessary for you. However, if you like the security and convenience of arriving to a new and unfamiliar destination without getting lost or wasting time, then a portable vehicle GPS device will become an indispensable automotive accessory you won't want to drive away from home without. by jonchan

Natural Colon Cleanser Secrets - How To Choose The Best Herbal Colon Cleansers

As the popularity of colon cleansing grows, more and more people are searching for the best natural colon cleanser. As with anything else these days, some herbal colon cleansers are better than others -- and narrowing down the field can be a chore at best. In this brief article, I'm going to discuss a few key points to consider when it comes to choosing an herbal colon cleanser. Hopefully by the time you've finished reading, you'll have a better understanding of what to look for and be on your way to better internal health.
One of the first things that you should always look at when it comes to natural colon cleansers is the company making the supplement. Is the company a trustworthy outfit that has been around for some time, or is it a fly-by-night startup without much of a track record? Don't get me wrong -- there are certainly startups that have put out solid products, but I always feel most comfortable dealing with a company that has a history and strong track record.

Another thing to consider as you're evaluating herbal colon detox programs is ingredients. It's important that the ingredients are of the highest quality and don't produce unwanted negative side-effects.

Ultimately, the colon cleansing program that you choose will determine whether you obtain fantastic results, or none at all. The best colon cleansers have been proven to benefit people in a variety of ways, including relieving constipation, IBS (irritable bowel syndrome), colitis, fatigue, skin problems such as acne and eczema, and much more. Be sure to choose your program wisely.

Hopefully this short article has given you a few points to consider as you're trying to find the best natural colon cleanser. Just remember that while they all come in pretty packages with compelling sales pitches, not all herbal colon cleansing programs are created equal.

A partnership between UBC, government and the pulp and paper industry has resulted in the development of three high efficiency pulp screen rotors that produce high quality paper while reducing almost half the energy required.

“There are currently 300 pulp screens in British Columbia’s 20 pulp and paper mills,” says UBC Mechanical Engineering Assoc. Prof. James Olson. “The industry consumes almost 20 per cent of all the electricity produced in the province and pulp screening is an energy intensive operation in that process.”

Pulp screens work somewhat like the spin cycle in a household washing machine by rotating at high speeds and forcing pulp through narrow openings in the screen. Pulp screens in B.C. alone consume 300 Gigawatt Hours per year at an estimated cost of $16 million -- or enough energy to light up 15,000 homes.

Olson and fellow UBC engineers Carl Ollivier-Gooch and Mark Martinez, along with industrial partners at Montreal-based Advanced Fiber Technologies Inc., took inspiration from aerospace technology and designed a family of uniquely shaped, hydrodynamic rotors that significantly reduce drag and operate at much lower speeds and power, while increasing the capacity and efficiency of the screen.

The technology was patented and licensed to Advanced Fiber Technologies and 100 new rotors were installed in 30 mills across Canada.

“The trial results were beyond everyone’s expectations -- reducing electricity consumption by 52 per cent compared to current state-of-the-art rotors,” says Olson. “If all pulp screens used in B.C. mills were converted to the new rotor technology, an estimated $8 million could be saved each year. Adopted nation-wide, the industry could save $20 million a year.”

While the cost savings would increase the industry’s competitiveness against new paper producers such as China, the reduced energy usage also translates into lower greenhouse emissions. The new technology could also cement Canada’s leadership in pulp equipment manufacturing and further diversify a sector that currently logs $53 billion in sales and $44 billion in exports per year.

As a result of the success in the mill trials, the research team has won BC Hydro’s New Technology of the Year Award (2007), the Natural Sciences and Engineering Research Council of Canada (NSERC)’s Synergy Award for Partnership and Innovation (2007), and the British Columbia Innovations Council’s Lieutenant Governor’s Award (2008).

The work has also led to a $2.2 million investment from the Natural Sciences and Engineering Research Council of Canada and a partnership with 11 industry partners including BC Hydro and most of the paper mills in B.C.

“There’s a gap between electricity supply and demand in B.C. and we need to do more to conserve power,” says Lisa Coltart, BC Hydro’s director of Power Smart. “We’re excited to contribute to research that will provide substantial energy savings while making the province a world leader in the field.”

Supercomputer time allocation to boost simulations of exploding stars


The U.S. Department of Energy has allocated 70 million processor hours on the IBM Blue Gene/P supercomputer at Argonne National Laboratory to the University of Chicago's Center for Astrophysical Thermonuclear Flashes.

The Blue Gene/P supercomputer is the world's fastest open-science computer. Access to the Blue Gene/P was made possible by a time allocation from the DOE's Innovative and Novel Computation Impact on Theory and Experiment program (INCITE).

The INCITE award will permit Flash Center scientists to virtually incinerate white dwarf stars, which pack one-and-a-half times the mass of the sun into an object the size of Earth. When white dwarfs explode, they produce type Ia supernovas, which evidence indicates manufactures most of the iron in the universe.

A better understanding of type Ia supernovas could help solve the mystery of dark energy, one of the grandest challenges facing today's cosmologists. Dark energy is somehow causing the universe to expand at an accelerating rate. Gravity should have been causing the expansion, which followed the big bang, to become slower with time.

In the simulations at Argonne, the Flash team will analyze how burning occurs in four possible scenarios that lead to type Ia supernovas. The Flash Center's findings could potentially impact the design of the instruments, scientific observing strategy, and analysis and interpretation of data for the Joint Dark Energy Mission, a partnership between NASA and DOE.

The Flash Center was founded in 1997 with a contract from the Office of Advanced Simulation and Computing of DOE's National Nuclear Security Administration (NNSA). The NNSA's Academic Strategic Alliance Program has sustained the Flash Center with funding and computing resources throughout its history.
