The Ring Eclipse

May 19, 2012 - Posted in Science

Diamond ring effect is a feature of a total solar eclipse. Just before the sun disappears or just after he emerged from behind the moon, rugged lunar limb topography allows beads of sunlight to shine. This effect is called the Baily beads, in honor of Francis Baily who first noted this phenomenon in 1836.

Disturbed by the smooth topography of the lunar mountains, craters, valleys, etc., and the lunar limb profile are known accurately from grazing occultation of stars, making it possible to make advance decisions are pretty good from the mountains and valleys that will cause the beads to appear. While Baily beads are visible for several seconds in the middle of the eclipse path, they were seen again near the edge of the path of totality.

Diamond ring effect is seen when only one of the remaining beads, arranged in a diamond shining bright ring around the silhouette of the moon.

Cosmas Damian Asam realistic painter might start to describe a total solar eclipse and a diamond ring of his paintings were completed in 1735.

It is not completely safe to view Baily beads or diamond ring effect without proper eye protection because in both cases are still visible photosphere.
According to NASA, the eclipse will begin at sunrise local time in southern China, then pass through Hong Kong; Taipei, Taiwan, and Tokyo before hitting the biggest so far in the Pacific Ocean near Alaska’s Aleutian Islands. After entering California, the shadow of the moon will block almost all sunlight from Reno, Nev., the Grand Canyon in Arizona, Albuquerque, NM, and Lubbock, Texas.

Zone where a partial eclipse can be seen much more extensive, stretching over most of eastern China, Korea, the Philippines, Siberia, Hawaii, Canada and Mexico. NASA has posted the calculation of the solar eclipse in the United States and abroad.

NASA has also set up an interactive Google map showing time eclipse – click on the map and it will show when the eclipse begins and ends at a certain point in the world. The time is set for “Coordinated Universal Time,” which is seven hours ahead of California.

Different annular eclipse total eclipse, in which there is no “ring of fire” look.

A word of warning: Never look directly into the sun during an eclipse! Experts say it is possible to cause permanent damage to vision. Here’s one way to make a simple pinhole projector to view the eclipse, and NASA also recommends using binoculars for eclipse project on a white card.

Untuk mengatasi kecanduan rokok memang sulitnya minta ampun ada saja godaan yang bisa membuat kita selalu lari ke rokok, sebuah metode baru ditemukan dengan cara merangsang bagian tertentu pada otak dapat memanipulasi keinginan untuk merokok. Temuan ini diyakini bisa menjadi metode pengobatan baru untuk membantu orang mengusir kebiasaan merokok tersebut.

Menggunakan teknologi scan otak, para peneliti dari Duke University Medical Center mengidentifikasi daerah otak yang menjadi aktif ketika mencandu rokok, yaitu korteks serebral dan sistem limbik yang berperan dalam pengaturan emosi. Berdasarkan penelitian ini, peneliti kemudian menggunakan stimulasi magnetik ke daerah-daerah otak untuk memanipulasi hasrat merokok. Readmore »

Treatment Flesh-Eating Disease

May 11, 2012 - Posted in Disease

Generally known as flesh eating disease or flesh-eating bacteria syndrome, is a rare infection of the deeper layers of skin and subcutaneous tissues, easily spreading in the plane fascia in the subcutaneous tissue.

Because more than 70% of cases recorded in patients with one of the following clinical situations: immunosuppression, diabetes, alcoholism / drug abuse, malignancy, and chronic systemic diseases. This sometimes occurs in people with apparently normal general condition.

The infection begins locally at sites of trauma, which may be severe (such as operating results), small, or even not clear. Patients usually complain of pain that may seem excessive given the outward appearance of the skin. With the progression of the disease, often within a few hours, tissue becomes swollen. Diarrhea and vomiting are also common symptoms. Necrotizing fasciitis is a rapidly progressing disease and severe abrupt onset and usually immediately treated with high doses of intravenous antibiotics.

Patients are usually brought into operation based on high index of suspicion, is determined by the patient’s signs and symptoms. In necrotizing fasciitis, aggressive debridement (removal of infected tissue) is always required in order not to spread and is the only treatment available. Diagnosis was confirmed by visual examination of the tissue and the tissue samples sent for microscopic evaluation.

Initial medical treatment is often alleged, therefore, antibiotics should be started immediately after the condition is suspected. Initial treatment often includes a combination of intravenous antibiotics, including penicillin, vancomycin, and clindamycin. Culture is taken to determine the scope of appropriate antibiotics, and antibiotics may be changed when the culture results obtained.

As in other diseases characterized by a large wound or damaged tissue, hyperbaric oxygen treatment can be a valuable adjunctive therapy but are not widely available Amputation of the affected organ may be required. Repeat explorations usually need to be done to remove additional necrotic tissue. Typically, this leaves a large open wound, which often require skin grafting. Associated systemic inflammatory response is usually deep, and most patients will require monitoring in the intensive care unit.

Treatment for necrotizing fasciitis may involve an interdisciplinary treatment team. For example, in cases of necrotizing fasciitis involving the head and neck, the team may include otolaryngologists, intensivists, microbiologists and plastic surgeons.
