ALZHEIMER DISEASE IS CALLED " SILENT KILLER "




Alzheimer's disease (AD), also called Alzheimer disease or simply Alzheimer's, is the most common cause of dementia. Alzheimer's is a degenerativeand terminal disease for which there is no known cure. In its most common form, it afflicts individuals over 65 years old.Alzheimer’s disease is a brain disorder named for German physician Alois Alzheimer who first described it in 1906. Scientists have learned a great deal about Alzheimer’s disease in the century since Dr. Alzheimer first drew attention to it.


WARNING SIGNS OF ALZHEIMER:-

1. Memory loss.

2. Difficulty performing familiar tasks.

3. Problems with language.

4. Disorientation to time and place.

5. Problems with abstract thinking.

6. Poor or decreased judgement.

7. Misplacing things.

8. Changes in mood or behavior.

9. Changes in personality.

10. Loss of initiative.



RISK FACTORS YOU MAY BE ABLE TO INFLUENCE:-


1. HEAD INJURY.

2. HEART-HEAD CONNECTION.

3. GENERAL HEALTHY AGING.

4. Deterministic genes directly cause a disease, guaranteeing that anyone who inherits them will develop the disorder.

5. Risk genes increase the likelihood of developing a disease, but do not guarantee it will happen.



DIAGNOSING ALZHEIMER'S :-


1. Time to make choices that maximize quality of life
2. Lessened anxieties about unknown problems
3. A better chance of benefiting from treatment
4. More time to plan for the future



TREATMENT OF ALZEIHMER'S :-


1. Cholinesterase drugs.

2. Memantine drugs.

3. Vitamin E may help because it is an antioxidant, a substance that may protect nerve cells from certain kinds of chemical wear and tear.

4. Phosphatidylserine lipids.

5. Omega 3-fatty acids.

6. Huperzine A.

7. Ginkgo biloba.

8. Coral calcium.

9. Co enzyme Q10.

MYSTERY OF BLACK HOLE IN SPACE


A black hole is a region of space into which matter has collapsed and out of which light may not escape. There are two main types-the Schwarzschild black hole that does not rotate and the Kerr black hole that does. Scientists today call such an object a black hole. Though the history of the term is interesting, the main reason is that no light can escape from inside a black hole: it has, in effect, disappeared from the visible universe.
A black hole is a simple object that has only a "center" and a "surface”. According to the general theory of relativity, distortions of space and time around the star become increasingly pronounced, and light rays emitted from the star's surface followed curved paths rather than straight lines. A non-rotating black hole has only two parts: a singularity, where all of the mass is located, and a surrounding event horizon. The distance from the singularity to the event horizon is called the Schwarzschild radius.
Inside the event horizon, the escape speed exceeds the speed of light, so the event horizon is a one-way surface. Things can fall in, but nothing can get out. A rotating black hole is surrounded by a region called the ergo sphere, where the dragging of space and time around the hole is so severe that nothing can remain at a fixed location. Because the ergo sphere is outside the event horizon, this bizarre region is accessible to us, and astronauts or asteroids could travel through it without disappearing into the black hole. The ejected object could leave the ergo sphere with more energy than it had initially, having extracted added energy from the hole's rotation. This is called the Penrose process.

INCREDIBLE MYSTERY OF BERMUDA TRIANGLE


No doubt you have wondered about the Bermuda Triangle. It is the greatest modern mystery of our supposedly wellunderstood world: a region of the Atlantic Ocean between Bermuda, Miami, Florida, and San Juan, Puerto Rico, where explanation.
Over the past century, hundreds of ships and planes have gone missing in a mysterious stretch of water in the Atlantic Ocean called the Bermuda Triangle. Is there a scientific explanation for these disappearances.The Bermuda Triangle, also known as the Devil's Triangle, is a region of the northwestern atlantic ocean in which a number of aircraft and surface vehicles have disappeared.The boundaries of the Triangle vary with the author; some stating its shape is akin to a trapezoid covering the straits of florida, the Bahamas, and the entire caribbeean island area east to the azores; others add to it the Gulf of Mexico. The more familiar, triangular boundary in most written works has as its points somewhere on the Atlantic coast of florida,Puerto rico; and the mid-Atlantic island of Bermuda, with most of the accidents concentrated along the southern boundary around the Bahamas and the Florida Straits.

Researchers and Scientistslink between methane gas blowouts and the Bermuda Triangle myth. He stated that massive landslides often occur along the North American continental shelf, which lies to the north of the Bermuda Triangle.


Such land slumps can occur over a large area bringing down huge boulders which rupture the layer of gas hydrate beneath the sea floor, freeing the gas that is trapped beneath the hydrate ‘cap’ and also liberating huge amounts of methane trapped within the hydrate itself. The moment a methane gas pocket ruptures a vast reservoir of gas suddenly surges from the seabed, rising up in a huge plume before erupting on the surface within seconds and without warning. A ship caught in such a blowout would be doomed; the water beneath it would suddenly become much less dense, sinking it in a matter of moments. The vessel would plunge into the depths, where it would be covered as sediment disturbed by the blow out settles back on the sea floor. In fact, planes too could fall prey to such a deadly fallout. Till today no one can find the mystery of bermuda triangle.Several theories and explanations and hypothesis are failed to explain this mischivious and incredible event. So, no ships can cross the bermuda triangle and no aircrafts can roaming and fly above the bermuda triangle.

If we dug the earth to about 8400 k.m. then you put ball into hole. The result is the ball oscillates and never comes in static positions.
