The rapid growth of technology, upgradation of technical innovations and a high rate of obsolescence in the electronics industry have led to one of the fastest growing waste streams in the world which consist of end of life electrical and electronic equipment products. It comprises a whole range of electrical and electronic items such as … Read more
Nanotechnology relates to the technology of rearranging and processing of atoms and molecules to fabricate material to Nano specifications such as nano meters, the technology will enable scientist and engineers to see and manipulate matter at the molecular level atom by atom create new structure with fundamentally new molecular organic material and exploit the novel … Read more
Newton’s First Law of Motion states that a body continue to be in its state of rest or of uniform motion along a straight line, unless it is acted upon by some external force to change the state (1) If no net force acts on a body, then the velocity of the body cannot change i.e. … Read more
It is a deflecting force experienced due to rotation of earth. Because of Coriolis the air appears to turn towards its right in the northern hemisphere and towards its left in the southern hemisphere. The coriolis always acts in the perpendicular direction of the motion of air. It is zero at the equator and increases … Read more
(a)LED: Led is light emitting diode. It is a pn junction diode, which emits light when gets activated. When a suitable energy is applied , electron combines with the electron holes within the device releasing energy in the form of photons.LED lamps have a lifespan and electrical efficiency which are several times longer than incandescent … Read more
(a)Male and Female reproductive organ: The male reproductive organs include a pair of testes (singular, testis), two sperm ducts and a penis. The testes produce the male gametes called sperms. The female reproductive organs are a pair of ovaries, oviducts (fallopian tubes) and the uterus. Ovary produces female gametes called ova (eggs). (b)Asexual production: It is a … Read more
Gametogenesis : The gametogenesis is the formation of gametes i.e. sperm in males and ovum in females. It is also known as spermatogenesis and Oogenesis. Insemination: Insemination is the deliberate introduction of sperm into a female animal or plant for the purpose of impregnating or fertilizing the female for sexual reproduction. The sperm is introduced … Read more
Coal bed methane is found in the impermeable stone and is trapped in the coal seams. A significant portion of this gas remain as free gas in the joints and fractures of the coal seam. Large quantities of gas are adsorbed on the internal surfaces of the micropores within the coal itself Coal bed methane … Read more
Blood circulates in our body and it transport substance like digested food from the small intestine to the other parts of the body. It carries oxygen from lungs to the cells of the body. It also transport waste for removal from the body. Major components of Blood are as follows: Plasma: Plasma is the liquid … Read more
