Bald Eagle

On July 12, 1995, the bald eagle was reclassified from endangered to threatened in the lower 48 states. It is the first and only Montana threatened or endangered species to be downlisted since the 1973 Endangered Species Act became law.

Bald eagle numbers, estimated at a quarter of a million in the lower 48 states before 1800, declined steadily throughout the late 1800s and early 1900s. Raptors at this time were regarded as vermin and shot on sight.

The Bald Eagle Protection Act of 1940 increased public awareness and made indiscriminate shooting, poisoning, collecting, and trading of bald eagles illegal, stemming the decline for a time. Yet, the advent of DDT and related pesticides during World War II and their widespread post-war use soon caused eagle reproduction to plummet. In 1963, a National Audubon Society survey reported only 417 active nests in the lower 48 states.

Blood Cancer

Transplants of special cells in the blood stream may be more effective than bone marrow transplants in patients who receive high-dose chemotherapy for blood cancer, according to a large randomized trial reported in the New England Journal of Medicine on January 18, 2001.

Physicians use both kinds of transplants in blood cancers such as leukemia and lymphoma, primarily to restore bone marrow destroyed by high-dose chemotherapy. In this study, the transplanted cells from the blood stream - known as peripheral blood cells -- took effect more quickly than the marrow transplants, without increasing the risk of complications.

Led by William Bensinger, M.D., at the Fred Hutchinson Cancer Research Center in Seattle, Wash., the researchers compared the two kinds of transplants in 172 patients from between 12 and 55 years of age. Patients were randomly assigned to two groups, one to receive the marrow transplants and the other to received the peripheral blood cells. Both transplants were allogeneic -- came from relatives -- and were given after high doses of chemotherapy with or without radiation therapy.

The patients in the trial who received peripheral blood cells recovered from the effects of the high-dose chemotherapy more quickly than those who received bone marrow transplants. Their blood counts -- the numbers of white blood cells and platelets -- returned to normal levels five or six days faster and they required fewer transfusions of platelets.

Wooden ceiling fan

An innovative carpenter gifted with a technical bent of mind has developed a variety of ceiling fans made of wood.Carpenter-technician Suresh Sharma, 40, claims that all of the 104 models of fans have been designed and developed by him. These handmade fans are unique and different as none of the designs have been repeated or copied. The smallest fan in his collection is an 8-inch fan and the biggest one being 11 feet long!

The wooden body fans that run by electricity like normal ceiling fans, have earned him quite popularity here. These fans captivate attention, as one finds blades of ceiling fans made of wood. The users can enjoy cool air.

Gibraltar Airport

Gibraltar Airport is the civilian airport that serves the British Overseas Territory of Gibraltar on the Iberian Peninsula. It is owned by the Ministry of Defence for use by the Royal Air Force as RAF Gibraltar. Civilian operators use the airport; currently the only scheduled flights operate to the United Kingdom and Spain. Passengers depart and arrive through the civilian operated terminal.

The airport was constructed during World War II upon the colony's race course, when Gibraltar was an important naval base for the British. Originally opened in 1939, it was only an emergency airfield for the Royal Navy's Fleet Air Arm. However, the runway was later extended by reclaiming some land from the sea of the Bay of Gibraltar which Spain claims are their territorial waters, causing diplomatic tensions between Spain and Britain. This extension of the runway allowed larger aircraft to land at Gibraltar.

Whale Shark - Biggest fish in the world

Whale Shark Biggest fish in the world. Whale Shark the largest kind of sharks, and also largest of nowadays living fishes. Whale sharks often grow to 45 feet and 15 is not a “Whale” it is a “Shark”. Given its name because of its sheer size, Rhincodon typus was first identified off the coast of South Africa in 1828.

Despite the impressive sizes, the whale shark is absolutely safe for the humans, as eats like a whale, exclusively plankton and other small organisms which it filters, involving in itself water.

Whale Shark migrations are thought to be timed with blooms of these platonic organisms often governed by changes in water temperatures. Attracted to warm waters they are found most commonly in a global band around the equator between 30 - 40° latitude.

Kargil War

Kargil War was a war between Indian and Pakistani forces in Kargil in 1999. Pakistani Kashmiris sent its troops inside the disputed territory of Kashmir to occupy military posts vacated in the winter. India then sent its army to fight the intruders from Pakistan-administered Kashmir and retake Indian-held Kargil.

After two months of fighting, the Indian Army won the war after Pakistani forces were pushed back to their original positions behind the LoC. The whole world also supported India in this war as Pakistan was criticised. This was the fourth war between the two neighbours. The war was very important because both India and Pakistan had nuclear weapons. The USA and other countries played an important role in the diplomacy during the war. After the war ended, a military coup took place in Pakistan.

The war is one of the most recent examples of high altitude warfare in mountainous terrain, which posed significant logistical problems for the combating sides. This was only the second direct ground war between any two countries after they had developed nuclear weapons, after the Sino-Soviet border conflict of 1969; it is also the most recent.The conflict led to heightened tension between the two nations and increased defence spending by India. In Pakistan, the aftermath caused instability of the government and the economy, and, on October 12, 1999, a coup d'etat by the military placed army chief Pervez Musharraf in power.

Hand Brake

The hand brake is a latching brake usually used to keep the car stationary.Automobile e-brakes usually consist of a cable directly connected to the brake mechanism on one end and to some type of lever that can be actuated by the driver on the other end. The lever is traditionally and more commonly a hand-operated system, the most common configuration being a handle on the floor between the driver and front passenger, and less commonly being a handle bar located on the lower portion of the dashboard somewhere close to the steering wheel column or between the driver and his or her door. Alternatively, the lever can be on the floor between the driver and the door or foot-operated, in the form of a pedal in the foot well in front of the driver, located to the far left apart from the other pedals.

Although sometimes known as an emergency brake, using it in any emergency where the footbrake is still operational is likely to badly upset the brake balance of the car and vastly increase the likelihood of loss of control of the vehicle, for example by initiating a rear-wheel skid. Additionally, the stopping force provided by using the handbrake instead of or in addition to the footbrake is usually small and would not significantly aid in stopping the vehicle, again because it usually operates on the rear wheels which suffer reduced traction compared to the fronts while braking. The emergency brake is instead intended for use in case of mechanical failure where the regular footbrake is inoperable or compromised, hopefully with opportunity to apply the brake in a controlled manner to bring the vehicle to a safe, if gentle halt before seeking service assistance. Modern brake systems are typically very reliable and engineered with failsafe (e.g. dual-circuit hydraulics) and failure-warning (e.g. low brake fluid sensor) systems, meaning the handbrake is no longer often called on for its original purpose.
