Logic circuit for Digital system may be combinational or sequential. A combinational circuit consists of Logic Gates whose output at any time are determined from the present combination of input. A Boolean circuit perform an operation that can be specified logically by a set of Boolean function. Each input and […]

Introduction: Electro- electricity, phoresis- to carry across. Electrophoresis is the migration of charged molecules in solution in response to an electric field. It is a method of separation of macromolecules like nucleic acids, carbohydrates, proteins, etc on the basis of charge and mass. It is a simple yet highly sensitive […]

In nature orchid seeds grow just after contamination by mycorrhizal organisms that furnish the creating fetus with water, sugars, minerals, and vitamins. Orchid seeds were initially developed at the base of wild-gathered pruned orchids, yet germination was problematic and seedling death rates were high. In vitro germination strategies, which were […]

Nursery creation is turning out to be progressively subject to innovation. The aggregate zone of nurseries, including ornamentals, is expanding and shoppers are requesting higher quality produce. The nursery business is reacting to these difficulties through the reception of new nursery structures, progressed natural alteration advances and creative nursery administration […]

The resolving power of an instrument is a measure of how well it can distinguish between two (apparently) very close sources of light. To illustrate this we will consider an astronomical telescope. Even when using a telescope of high magnification, the image of a star should be a very small […]

An optical fiber (or optical fiber) is an adaptable, straightforward fiber made by drawing glass (silica) or plastic to a width somewhat thicker than that of a human hair.[1] Optical filaments are utilized frequently as a way to transmit light between the two finishes of the fiber and find wide […]

Vertical nursery is an option for the individuals who want to appreciate plants as a type of Green Lifestyle however is obliged by restricted space for planting. The idea of the recreation center was found in 1994 by the French botanist right now created with a scope of developments to […]

A transgenic crop plants are those which has a gene or genes been unnaturally introduced to the plant rather than acquiring them through pollination. The inserted gene sequence can be taken from dissimilar plant, or from an entirely diverse species: transgenic Bt cotton, for example, generates its own insecticide, as […]

The cytoplasmic hybrids, Where the nucleus is derived from only one parent and the cytoplasm is derived from both the parents are referred to as Cybrid or Cytoplast ( Cytoplasmic hybrids). The Phenomenon of formation of cybrids is regarded as Cybridization. Applications of Cybrids (i) Cybrids are important for the […]

Cell commits suicide by apoptosis. Cellular homicide is necrosis Apoptosis (from Ancient Greek word “falling off”) is a process of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death. Physiologic causes: 1)The programmed destruction of cell during embryogenesis. It is programmed […]
