Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the biological development of a cellular form of life or a virus. All known cellular life and some viruses have DNAs. DNA is a long polymer of nucleotides (a polynucleotide) that encodes the sequence of amino acid residues in proteins, using the genetic code.
Doppler shift-The "police siren" effect,when waves propagated by a moving body have their wavelength stretched as the body moves away.
Diurnal motion: The apparent daily rotation of the sky from east to west. It is due to the real rotation of the earth from west to east.
Dichotomy: The exact half-phase of Mercury, Venus or the Moon.
DiureticA diuretic (colloquially called a water pill) is any drug or herb that elevates the rate of bodily urine excretion (diuresis). Diuretics also decrease the extracellular fluid (ECF) volume, and are primarily used to produce a negative extracellular fluid balance. Caffeine, cranberry juice and alcohol are all weak diuretics. UsesIn medicine, diuretics are used to treat heart failure, liver cirrhosis, hypertension and certain kidney diseases. Diuretics alleviate the symptoms of these diseases by causing sodium and water loss through the urine. As urine is produced by the kidney, sodium and water – which cause edema related to the disease – move into the blood to replace the volume lost as urine, thereby reducing the pathological edema. Some diuretics, such as acetazolamide, help to make the urine more alkaline and are helpful in increasing excretion of substances such as aspirin in cases of overdose or poisoning.The antihypertensive actions of some diuretics (thiazides and loop diuretics in particular) are independent of their diuretic effect. That is, the reduction in blood pressure is not due to decreased blood volume resulting from increased urine production, but occurs through other mechanisms and at lower doses than that required to produce diuresis. Indapamide was specifically designed with this is mind, and has a larger therapeutic window for hypertension (without pronounced diuresis) than most other diuretics.

Delta-aminolaevulinic acid dehydratase http://pir.georgetown.edu/pirwww/images/pdb/1H7Nx500c.jpgLead poisoningLead has no known biological role in the body. The toxicity comes from its ability to mimic other biologically important metals, the most notable of which are calcium, iron and zinc. Lead is able to bind to and interact with the same proteins and molecules as these metals, but after displacement, those molecules function differently and fail to carry out the same reactions, such as in producing enzymes necessary for certain biological processes.Most lead poisoning symptoms are thought to occur by interfering with an essential enzyme Delta-aminolevulinic acid dehydratase, or ALAD. ALAD is a zinc-binding protein which is important in the biosynthesis of heme, the cofactor found in hemoglobin.Genetic mutations of ALAD cause the disease porphyria, a disease which was highlighted in the movie The Madness of King George.Lead poisoning is sometimes mistaken for porphyria but the distinction is that lead poisoning usually causes anemia while true porphyria does not.more from Wikipedia clicking here: http://en.wikipedia.org/wiki/Lead_poisoning

DendrochronologyDendrochronology or tree-ring dating is the method of scientific dating based on the analysis of tree-ring growth patterns. This technique was invented and developed during the 20th century originally by A. E. Douglass, the founder of the Laboratory of Tree-Ring Research at the University of Arizona. The technique can date wood to exact calendar years.OverviewMany trees in temperate zones grow one growth ring each year, the newest ring being under the bark. For the entire period of a tree's life, a year-by-year record or ring pattern is formed that reflects the climatic conditions in which the tree grew. Adequate moisture and a long growing season result in a wide ring. A drought year may result in a very narrow one. Trees from the same region will tend to develop the same patterns of ring widths for a given period. These patterns can be compared and matched ring for ring with trees growing in the same geographical zone and under similar climatic conditions. Following these tree-ring patterns from living trees back through time, chronologies can be built up, both for entire regions, and for sub-regions of the world. Thus wood from ancient structures can be matched to known chronologies (a technique called cross-dating) and the age of the wood determined precisely. Cross-dating was originally done by visual inspection. Nowadays, computers are used to do the statistical matching.To eliminate individual variations in tree ring growth, dendrochronologists take the smoothed average of the tree ring widths of multiple tree samples to build up a ring history. This process is termed replication. A tree ring history whose beginning and end dates are not known is called a floating chronology. It can be anchored by cross-matching either the beginning or the end section against the end sections of another chronology (tree ring history) whose dates are known. Fully anchored chronologies which extend back more than 10,000 years exist for river oak trees from South Germany (from the Main and Rhine rivers). A fully anchored chronology which extends back 8500 years exists for the bristlecone pine in the Southwest US (White Mountains of California).In areas where the climate is reasonably predictable, trees develop annual rings of different properties depending on weather, rain, temperature, etc. in different years. These variations may be used to infer past climate variations — [ Invalid Attachment ]

DialysisIn medicine, dialysis is a type of renal replacement therapy which is used to provide an artificial replacement for lost kidney function due to renal failure. It is a life support treatment and does not treat any kidney diseases. Dialysis may be used for very sick patients who have suddenly lost their kidney function (acute renal failure) or for quite stable patients who have permanently lost their kidney function (end stage renal failure). When healthy, the kidneys remove waste products (for example potassium, acid and urea) from the blood and also remove excess fluid in the form of urine. Dialysis treatments have to duplicate both of these functions as dialysis (waste removal) and ultrafiltration (fluid removal).
DiodeSemiconductor electronic component. Ideally, a diode conducts electricity in one direction and does not allow the current to flow in the opposite direction. Thanks to this property diodes are used to rectify alternating currents, i.e., to convert alternating current (AC) to direct current (DC).

History of the Depth ChargeThe depth charge or bomb is a waterproof weapon used by ships or aircraft to attack submerged submarines.First Depth ChargesThe first depth charges were developed by the British in World War I for use against German submarines or U-boats, beginning in late 1915. They were steel canisters, the size of an oil drum, filled with TNT explosives. They were dropped off the side or stern of a ship, on top of where the crew estimated the enemy submarines were. The canister sank and exploded at a depth that was preset by the use of a hydrostatic valve. The charges often did not hit the submarines but the shock of the explosions still damaged the submarines by loosening the submarine enough to create leaks and forcing the submarine to surface.The first depth charges were not effective weapons. Between 1915 and the end of 1917, depth charges destroyed only nine U-boats. They were improved in 1918 and that year were responsible for destroying twenty-two U-boats, when depth charges were propelled through the air over distances of 100 or more yards with special cannons, increasing the damage range of the naval ships.
