American Indians...

The findings, from the largest longitudinal, population-based study of cardiovascular disease and risk factors in American Indians showed that the stroke incidence rate was 679 per 100,000 person years for American Indians. Previous studies in persons of similar age found the stroke incidence rate 306 per 100,000 person years for whites and 607 per 100,000 person years for blacks. Moreover, first strokes appear to be more deadly in American Indians, said Ying Zhang, M.D., Ph.D., study lead author and assistant professor at the College of Public Health at the University of Oklahoma Sciences Center in Oklahoma City. The death rate was 18 percent within one month of stroke and 32 percent within one year of stroke.
Researchers cited high rates of hypertension, diabetes, and cigarette smoking in this population as a possible reason for the higher stroke incidence. They did not find an association between alcohol use and stroke incidence in this group. Each of these risk factors provides important avenues for intervention to reduce risk, researchers said. Researchers also found a strong association between stroke and protein in the urine which is a marker for kidney dysfunction that is often associated with diabetes. Researchers concluded further studies of the association between kidney function and stroke incidences are needed. Although the data indicate a higher stroke incidence among American Indians, the numbers were too small to compare stroke prevalence in this population with stroke prevalence in whites and blacks, she said. Incidence refers to the frequency of development of a new illness in a population in a certain period of time. Prevalence refers to the current number of people suffering from an illness in a given period of time, usually one year. Among American Indians age 18 and over, about 5.8 percent have had a stroke, compared to 3.4 percent of African-Americans and 2.3 percent among whites, according to the American Heart Association/American Stroke Association.Clinicians who care for American Indian patients can use the information to reduce their risk of stroke by providing appropriate treatment and by advising them to modify their lifestyle.

CURRY LEAF CHUTNEY

For this dish, called karivepaku pachchadi in Tamil, choose fresh, tender leaves for this blend of nutrition and flavour
INGREDIENTS
Curry leaves: 2 cups
Thick tamarind pulp:3 table spoon

Red chillies: 8-10; nicked at tail with stalks retained
Asafoetida powder or paste: 1 tsp
Turmeric powder:1/2 tsp
Coriander leaves: 1 cup; chopped roughly
2nd tempering
Split black gram (husked): 1/2 tsp
Mustard seeds:1/2
METHOD
Wash the curry leaves and pat dry. Heat 2 tbsp oil in a wok on a low flame and roast the curry leaves until crisp. Ensure they remain green. Set aside. In another wok, heat on-and-a-half tbsp oil for the first tempering. Add the gram; as it turns golden,add the mustard and then the cumin. Switch off the flame and add red chillies. As they turn bright red, stir in the remaining ingredients for the 1st tempering. Grind this along with curry leaves, tamarind pulp, jaggery and salt into a coarse paste. Do not add water while grinding. Heat the remaining oil for the second tempering. Garnish the chutney with this crunchy tempering. If you want to preserve for a longer period,avoid the coriander leaves.

coffee...

The coffee plant originates from the highland forests of Ethiopia. It is believed that the first plants were found growing wild in the region of Kaffa, where coffee derives its name. A popular legend tells of a goat herder named Kaldi. One day he noticed his goats behaving in a strange manner. They were full of energy, playfully chasing each other and bleating loudly. He noticed they were eating red berries from the bushes nearby. Feeling tired and slightly curious, Kaldi decided to try some of the berries. To his delight his fatigue quickly faded into a fresh burst of energy.
Kaldi was so impressed by the berries, that he filled his pockets with them and ran home to show his wife. "They are heaven-sent" she declared, "You must take them to the Monks in the monastery".
At the monastery, Kaldi told the Abbot how these berries had had a miraculous energizing affect on his goats. The Abbot hurled the berries into the fire and proclaimed them as the "Devil's work".Within minutes the berries started to smoke and the monastery was filled with the heavenly aroma of roasting beans. The other Monks quickly gathered to see what the commotion was. One Monk swiftly raked the beans from the fire and extinguished the embers by stamping on them. The rich smell of coffee obviously agreed with the Abbot's nose as he ordered the Monk to place the now crushed beans into a jug and cover it with hot water to preserve their divine goodness. He then took a sip from the jug and sampled the rich and fragrant brew that is coffee. From that day on the Monks vowed to drink coffee daily to keep them awake during the long, nocturnal devotions.

Earth's gravity!

Earth's gravity accelerates a falling object, whether it is a skydiver or a dropped glass, at a rate of nearly 10 meters per second. This means that aftr 10 seconds the object would be travelling at 100 metres per second or 360km/h.
Of cours, gravity is not the only force acting on a falling object. The faster an object goes through the air, the more the air resists it. Eventually the force of gravity and the air resistance balance each other out and the object stops accelerating. When this happens the object has reached its final speed, or terminal velocity. Terminal velocity depends on how much air resistance an object has-- for a skydiver it is around 190km/h.

JET START!! Newton’s third law says that for every action, there is an equal but opposite reaction. If you blow up a balloon and let it go, it shoots across the room. The action of the air blowing backwards out of the balloon produces the reaction that pushes the balloon forward. Whenever you push or pull an object it pushes or pulls you with equal force. A jet engine also works according to Newton’s third law. A powerful fan sucks air into the engine. The air is heated inside a combustion chamber, where fuel is burned. The heated air expands very rapidly and rushes from the back of the engine. This creates a reaction force or thrust on the engine that makes the aircraft fly forward.

HOW TO TAKE A GOOD PICTURE?

HOW TO TAKE A GOOD PICTURE? **Hold the camera steady. If you are taking a picture of, say, a child, try and take the shot from her eye level. It gives a clearer image of the subject. To be more adventurous, you can change angles to highlight certain features later. **Play around with light. Pictures are best taken in natural light. A sunny day is not the only time to shoot. Use your imagination to try other weather and light conditions. **Use artificial light or flash when needed. Most cameras are equipped with an automatic flash option and some even have fill-flash setting (to light up only those areas of the picture that require more illumination). You can even use flash on sunny day. Dont move beyond your flash range (usually between four and ten feet). **some helpful web addresses are: http://www. kodak.com/eknec http://www.airshowfan.com/guide-to-digital-ameras-3.htm http://www.bbc.co.uk/arts/apictureofbritain/how_to/ **Buy an expensive camera only after you have mastered the basics.
