Electrostatic

A thin, electrostatic ally charged diaphragm, is suspended between two perforated metal plates. The electrical sound signal is applied to the electrodes creating an electrical field; depending on the polarity of this field, the membrane is drawn towards one of the plates. Air is forced through the perforations; combined with a continuously changing electrical signal oscillating the membrane, a sound wave is generated.

Kinetic power

Some watches are powered by the movement of the wearer of the watch. Kinetic powered quartz watches make use of the movement of the wearer's arm turning a rotating weight, which in turn, turns a creator to supply power. The concept is similar to that of self-winding spring movements, except that electrical power are generated instead of mechanical motion alone.

Vegetable

Vegetable is a culinary term which usually refers to an edible part of a plant. The definition is traditional rather than scientific and is somewhat capricious and subjective. All parts of herbaceous plants eaten as food by humans, entire or in part are normally considered vegetables. Mushrooms, though belonging to the biological realm fungi, are also commonly considered vegetables. In general, vegetables are thought of as being savory, and not sweet, even though there are many exceptions. Nuts, grains, herbs, spices and culinary fruits (see below) are usually not considered vegetables.

Prevention

In medicine, prevention is any action which reduces the burden of mortality or morbidity from disease. This takes place at primary, secondary and tertiary prevention levels.Primary prevention avoids the development of a disease. Most population-based health support activities are primary preventive measures.Secondary prevention activities are aimed at early disease detection, thereby increasing opportunities for interventions to prevent progression of the disease and emergence of symptoms.Tertiary prevention reduces the negative impact of an already recognized disease by restoring function and reducing disease-related complications.

Malai

Malai is a South Asian term for clotted cream or Devonshire cream. It is made by heating non-homogenized whole milk to about 80ºC (180ºF) for about one hour and then allowing to cool. A thick yellowish layer of fat and coagulated proteins forms on the surface, which is skimmed off. The process is typically repeated to remove most of the fat. Malai has about 55% butterfat. Buffalo milk is thought to produce better malai because of its high fat content.Malai is used in such recipes as Malai Kofta dumplings and the sweet Malai Kulfi.
