Welcome to the brave new world of high-tech dentistry. Here, teeth stained by coffee, tea and tobacco are bleached considerably white in a single sitting, and crowned and laminated in a single visit. Infected gum tissue can be vaporized bloodlessly in a few minutes with lasers. Even thou..

As a result of sustained research in agriculture, many high yielding varieties /hybrids have been released in our countries (India 2000). In rice, more than 600 high yielding, early maturing, dwarf disease resistant varieties have been evolve..

Density of population in many cities and urban centers is so high that their respiration has caused imbalance in air composition. Their constant intake of oxygen and release of carbon dioxide has the potentiality to change the composition of ai..

Halogens have very high electron affinity values and therefore, have very strong tendency to gain an electron. Thus halogens are very reactive elements due to their low dissociation energies and high electron affinity values. As clear from the values of bond dissociation energi..

High Yielding Varieties / Hybrids - As a result of sustained research in agriculture, many high yielding varieties /hybrids have been released in our countries (India 2000). In rice, more than 600 high yielding, early maturing, dwarf disease resistant varieties have be..

In this process, coal is heated in the absence of air to about 1273 - 1473 K. The major products of high temperature pyrolysis are, Coal..

Ionic compounds have high melting and boiling points. A large amount of energy is required to break the crystal lattice, because the ions are held together by strong electrostatic forces of attraction. The variation in melting point depends upon the charges on the ions and ionic radii. T..

Wave trains for laser light may be several hundred kilometers long. Interference fringes can be set up by combining two beams that have followed separate paths whose lengths differ by as much as this amount. The corresponding coherence length for light from a tungsten filament lamp or a gas discha..

A laser beam departs from strict parallelism only because of diffraction effects, determined by the wavelength and the diameter of the exit aperture. Light from other sources can be made into an approximately parallel beam by a lens or a mirror, but the beam divergence is much greater than for las..

The molecule should contain an atom of high electronegativity such as F, O or N bonded to hydrogen atom. The common examples are H 2 O and NH 3..
