AT&T launches portable cellular antennas

U.S. telecommunications company AT&T sells the first to market small portable cellular antennas that will enable corporate and government customers to provide their own wireless coverage in remote or disaster areas affected, the company said today.

Typically, mobile telecom operators restore services in areas affected by disasters (eg hurricanes), sending a space truck with mobile antennas (towers). The product of AT & T will allow first recall the scene as police, civil protection, emergency medical, fire protection, etc., suddenly acquire control over the areas over which they have coverage.

Antennas are transported in a special case of which are installed when necessary and then returned to him. One possibility for choice, which offer the units is an additional satellite dish.

Remote Mobility Zone may serve up to 14 simultaneous calls and provide data at a rate lower than that of broadband. Coverage is up to half a mile from the antenna. Portable antenna can be mounted on the car or truck.

Remote Mobility Zone can be used with any cellular phone on AT & T.

The price of mobile units is between $ 15,000 and $ 45,000, being paid and additional monthly fees.

How To Tie A Tie

BEFORE you put your tie should buckle your shirt and primed to pick up the collar after it tie, collar back down, as should stand. The bottom of the tie should reach to the middle or upper end of the belt buckle you. Furthermore, a node in the middle, there must be hollow, otherwise the tie is not well tied. This concavity is obtained by placing your index finger under the knot and keep it there until the clamp.

Now for the very tethering. Here's the easiest and most popular way to tie a tie in 8 steps:

1. Tossed the tie so that its wide end to hang around 25-30 cm over the narrow end. Who will end your left and who - does not matter right, do it to you as you see fit.
2. Tossed the wide end over the narrow.
3. Stick wide end under the narrow.
4. Again tossed wide end over the narrow.
5. Stick the point end in the back of the neck around your neck, so out front.
6. Put your pointer in the emerging unit, not to tighten. Stick the point end in this node, so that visne down - the connection is nearly tied.
7. Now you can remove your finger and pull yourself together knots.
8. Hold the narrow end of tie knots and slid to the collar.

Earth Day 2011

Earth Day was first proclaimed in 1970 in the U.S. and Canada, is celebrated internationally since 1990, holiday in Bulgaria noted the 1993 goal is to unite people on the planet in environmental protection.

On April 22, 1970 was first celebrated International Day of the Earth. And millions of Americans participate in the demonstration and urge politicians, statesmen, business circles to include in their priorities of environmental protection. The first celebration of Earth Day is organized by Gaylord Nelson - former governor and senator from Wisconsin who raised the cause of conservation and Dennis Heyes - a prominent student leader. In the events of the first Earth Day to include more than 20 million Americans from all over the country. As a result of this event formed a powerful movement to protect the environment and have adopted laws on clean air and clean water of the United States.

Earth Day - April 22, is the largest non-religious holiday celebrated the world over half a billion people. Each year the International Network for Earth Day coordinate more than 12,000 partners in 174 countries aimed at protecting the Earth and preserve life on it. Network aims to create a broad civil support for sustainable and effective environmental policies for development worldwide.

Bulgaria is one of the first countries that joined the international celebration of Earth Day, which began in 1990 in the International Organizing Committee for the celebration of Earth Day, Bulgaria is represented by Blagovest Sendov. He formed the National Committee for Earth Day. The call for the celebration of Earth Day to respond thousands of Bulgarians and the day is celebrated with various events devoted to environmental protection. On April 22, 1992 President of the Republic of Bulgaria Zhelev signed the oath in the name of Earth. Over 30,000 Bulgarian children are signed under the Declaration of authority for life on Earth. The declaration was presented to the UN Conference on Environment and Development held in Rio de Janeiro in June 1992 Every year thereafter, Bulgaria participated in the celebration of Earth Day and contributes to a cleaner and healthier environment for storing life on the planet.

Minoxidil: mechanisms of action on hair growth

For nearly 30 years is known that minoxidil stimulates hair growth, yet the mechanism of action of this agent is not fully understood. In animal studies it was found that minoxidil shortens telogen phase, causing premature transition of resting hair follicles into anagen. It is very likely in humans minoxidil have the same mechanism.

Administered orally, minoxidil lowers blood pressure by relaxing the smooth muscle, it is believed that this pharmacological effect is due to minoxidil sulfate - a metabolite of minoxidil, which leads to the opening-up of ATP-dependent sarkolemni potassium channels. There are several reports which suggest that the incentive effect of minoxidil on hair growth is due to the opening of potassium channels of that metabolite, but no evidence that such channels are expressed in the hair follicle. A number of in vivo effects of minoxidil are described in monocultures of several skin and follicular cell lines: stimulation of cell proliferation, inhibition of collagen synthesis, stimulation of the synthesis of vascular endothelial growth factor and prostaglandins. Some of the described effects may be important for hair growth, but it is unclear how these results could be applied in the complex biology of the hair follicle. This article will describe what information has medicine on the mode of action of minoxidil on hair growth.

Minoxidil enter service in 70 years of 20 century as a medicine for hypertension. Even then found that one of the most common side effects of taking minoxidil tablets hypertrichosis. In bald men were seen re growing in fallen hair. All this led to the creation of minoxidil topical form for treatment of androgenetic alopecia in men, and later in women. 2% howl product against hair loss occurs in the U.S. market in 1986 and in 1993 appeared and 5-percent solution.

Despite 20 years intensive research, medicine has limited data exactly how minoxidil stimulates hair growth. By contrast, the establishment of the exact mechanism of action of the preparation is of utmost importance - in terms of creating more effective therapeutic approaches to hair loss and in terms of clarifying the biology of the hair follicle.

There are several mechanisms by which the drug stimulates hair growth. Minoxidil accelerates hair growth, increases the diameter of the hair affect the hair cycle shortened telogen and prolonging anagen phase. Probably integrated action include all these mechanisms. Available data suggest that minoxidil acts mainly through the influence of the hair cycle, perhaps increasing the diameter of the hair.

Animal studies

Mori and Uno studied the effects of topical minoxidil on spontaneous hair cycle in rats. No effect was found for the length of the anagen phase, but at the expense of this telogen phase was shortened: its duration during the third cycle in untreated animals was 20 days and in treated follicles had entered anagen phase only after 1-2 telogen. The same shortening of the telogen phase was observed and the fourth cycle.

The effect of minoxidil has been studied thoroughly in macaques - mammals who develop alopecia like humans. Topical minoxidil prevented the development of skalpovo baldness and stimulate re-growth of hair in balding individuals. Histological studies found that minoxidil causes increase in the number of follicles into anagen phase and reducing those in the telogen phase. Been established and enlargement of the hair follicle.

Studies in humans

Extremely little is known about the effects of minoxidil on hair growth in humans, such studies are limited mainly to the observed response to androgenic alopecia applications topical minoxidil. In male pattern baldness (male androgenetic alopecia), a gradual reduction in the duration of anagen and longer latent period of the hair follicle (the period between the loss of telogen hair and the beginning of the next anagen). Hair follicles shrink.

Clinical trials with topical minoxidil in male and female hair loss show extremely rapid acceleration of hair growth, which becomes apparent within 6-8 months after starting therapy. The peak is usually reached in weeks 12-16. Most likely, minoxidil affects hair follicles in telogen and latency induced transition into anagen. Hypertrichosis observed in oral administration may affect the forehead and limbs. Extended hairs of these sites indicate that minoxidil also extended the duration of the anagen phase in man.

Histological studies in man are less definitive than in macaques. Abel and colleagues found a trend towards increasing otnoshtenieto anagen / telogen after 12 months of treatment with minoxidil in the bald men, but the biggest change was an increase in the average diameter of hair ". This change was most evident at 4 months, and at 12 months was observed reduction in mean diameter - probably due to the passage of small arms in the anagen hair follicle.

Minoxidil sulphate opens potassium channels

Minoxidil sulfate is one of a number of chemically unrelated drugs that cause opening plazmomembranni ATP-sensitive potassium channels. Relaxing effect of minoxidil on smooth muscle is due to precisely this mechanism. K ATP are located in many tissues and cell types - cardiomyocytes, pancreas, vascular galdka muscle, central nervous system. Several reports of clinical observations, animal studies and in vitro experiments suggest that the incentive effect of minoxidil on hair growth is related in some way with the opening K.atf effect of the preparation.

In vivo studies
Furthermore, minoxidil, opening potassium channels preparations diazoxide and pinacidil also cause hypertrichosis in humans. Bulgarian and colleagues studied the effect of topical minoxidil and three other preparation that open channels on K.atf skalpoviya hair "growing on bald monkeys. Minoxidil, cromakalin and P-1075 (analogue of pinacidil) stimulated hair growth within 20-week treatment course. Fourth oupanar of potassium channels - RP-49, 356, was not effective.

Regardless of the mechanism by which minoxidil modulate hair growth, there should be a primary effect on cellular function. Hair follicle is a complex structure consisting of epithelial, dermal, pigments and immune cells, as well as perifolikularna vascular and nervous system. Regulation of epithelial growth and differentiation and the hair cycle is based on the above structures. Many of these cells were used in studies with isolated monoxidil, but so far attempts to lokalizarane connections between minoxidil (and metabolites) and some of these cells were unsuccessful. Studies in mice have shown that minoxidil and minoxidil sulfate were concentrated in melanocytes and pigmented epithelial cells in suprapapilarniya region of the follicle. Most likely this is due to nonspecific binding to melanin.

Why minoxidil important? Although the benefits of androgenetic alopecia has been demonstrated in numerous clinical trials tend to disparage the preparation, which remains the only topical medication proven efficacy, and the only drug for hair loss in women approved. Minoxidil affects hair cycle, causing premature termination of the telogen and perhaps extend the anagen phase. Clarifying the mechanisms by which minoxidil has its effects will not only lead to more effective treatment of hair loss, but will also improve our knowledge on mechanisms controlling the hair cycle.

U.S. suspended its participation in military action in Libya

From today the U.S. began to withdraw from active combat operations against the regime of Moammar Gadhafi in Libya, announced in April The Pentagon hopes that the European allies of U.S., NATO will deal with the regime in Tripoli, the agency said.

From now on air strikes against sites in Libya will be involved U.S. aircraft. In direct military action would not participate and American warships and submarines in the Mediterranean, which caused massive udars first cruise missile sites in Libya two weeks ago.

American warplanes and ships pass on standby if NATO command finds that it can not deal only with other participants in the operation. Commander Operation United defender 'may require U.S. aircraft to strike at targets, but this will be
the express consent of Washington.

Air strikes against the sites of Libyan regime continued, but they will be involved aircraft other NATO countries. American planes tanks and aircraft equipped for electronic warfare, will support NATO fighters that patrol over Libya in order to implement the ban on flights by Libyan aircraft.

Muammar Gaddafi still has full authority in areas under its control, despite signs emerged that many of his associates abandoned him.

White House hopes that if the government Gaddafi is not completely disintegrate in the next few days, continued its strikes against tanks, and land batteries zenith parts will at least seriously undermine its ability to withstand the pressure of re-gaining momentum rebellion against the regime Points
April
"He's still killing people," said President of the Council of Chief staffs of the U.S. armed forces, Admiral Michael Mullen. This is in recognition that the mission of the Western coalition has not yet achieved its goals, but with his retirement from active fighting U.S. already carry the promise to pass on the burden of France, Britain and other allies in NATO.

The White House has not yet announced its final decision on whether the U.S. will deliver weapons of opposition to Gaddafi. Some supporters in Congress of the mission in Libya believe that this measure would be crucial to the overthrow of the Gaddafi and the limitation of victims of internal conflict.

iPhone 5 with Sony Camera?

In fact, rumors that Apple will use the 8-megapixel sensor for the iPhone, which will present in 2011 were released on the internet before it was confirmed 5-megapixel sensor in the iPhone 4.

Shares of OmniVision, which is the incumbent chamber sensors to Apple, fell sharply last summer, when you are hearing that Apple is considering using sensors from Sony for the next versions of the iPhone. Same thing happened yesterday with the shares of OmniVision, which further confirms this rumor. Backlit sensor of the iPhone OmniVision 4 makes a very good HD video, but on the pictures, there are many complaints about the yellow shades in the images of birds, and false representation of color images in the open - things that can not be corrected by the backlit sensor. Therefore, this rumor seems quite credible, given that Apple wants to use only the best for their gadgets.

Since Apple may have their sights on the new sensor Exmor R chamber of Sony, as a Sony Ericsson Xperia arc and Xperia neo. 8-megapixel sensor is backlit and contributes to better shooting in poorly lit areas, like 5-megapixel sensor in the iPhone OmniVision 4. See the video below which shows the capabilities of the sensor Exmor R from Sony.

Also, Sony has a 16-megapixel Exmor R sensor that is embedded in your phone Sony Ericsson CyberShot S006, intended for the Japanese market. With the development of two Tegra processors, TI OMAP4 and Snapdragon, will soon have the opportunity for hardware support for more than 18 megapixel sensors. The amount of 8-megapixel Exmor R sensor that can occur in the next version of iPhone e 1/3.2 ".

This is far from the largest chamber in the phone sensor - 1/1.8 "the 12-megapixel sensor Nokia N8, but Sony has created a new way of arranging the photo diodes, which are adapted to the finer pixel structure and It should create sharper images with less noise in low light conditions. In the photos below you can see the advantages of backlit Exmor R sensor of Sony, which makes more detailed and bright images in comparison with a conventional 5-megapixel camera phone.

BlackBerry Touch
