What Is Mitosis? Mitosis is a cell division process whereby each parent cell divides into 2 daughter cells. The number of chromosomes in the mother cell is identical to each of the resulting daughter cell. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of … Read more
The process of converting the AC current into DC current is referred to as rectification. Rectification can be achieved by using a single diode or group of diodes. These diodes which convert the AC current into DC current are referred to as rectifiers. Rectifiers are generally classified into two types: Half wave rectifier Full wave … Read more
Monocot Root The tissue at the center of monocot roots consists of (vascular bundle) xylem and phloem and it is surrounded by the cortex which is made up of parenchyma cells. The outmost layer of the root is referred to as the epidermis followed by the endodermis or sclerenchyma. The endodermis is an inner layer … Read more
What Is Cohesion? Cohesive forces are the intermolecular forces such as those from hydrogen bonding and Van der Waals forces which cause a tendency in liquids to resist separation. These attractive forces exist between molecules of the same substance. For instance rain falls in droplets, rather than a fine mist, because water has strong cohesion … Read more
Nuclear Fission Nuclear fission of heavy elements was discovered in 1938 by German Otto Hahn and Fritz Strassmann. Nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei. This process usually produces free neutrons, gamma photons and releases a … Read more
What Is Fresnel Diffraction (Near-field Diffraction)? Fresnel diffraction also referred to as near-field diffraction is a form of diffraction which occurs when a wave passes through an aperture and diffracts in the near field, causing any diffraction pattern observed to differ in size and shape depending on the distance between the sources of the obstruction … Read more
Capstan and Turret lathe were first developed in the United States of America in 1960 by Whitney and Pratt. They are used for repetitive production of duplicate parts in the minimum time possible. The main parts of a capstan and turret lathe include: Bed Headstock Cross slide and saddle The turret saddle and auxiliary slide … Read more
What Is Lamina Flow? In fluid dynamics, laminar flow also referred to as streamline fluid flow, is a type of fluid flow in which the fluid travels smoothly or in regular paths. In laminar flow, the velocity, pressure and other flow properties at each point in the fluid remain constant. The motion of particles of … Read more
Scalar and vector quantities used to be a thorough subject of debate among physicists for many years. It took a lot of studies and papers for a clear difference between the two quantities to emerge. These days it is quite easy to make a distinction between a scalar and a vector quantity. Scalar Quantity … Read more
Polymerization describes the formation of large molecules (Polymers) with repeating structure from small molecules (monomers). There are two types of polymerization reactions, additional and condensation. Additional Polymerization Additional polymerization is a polymerization in which the growth of polymer chains proceeds by addition reactions between molecules of any size. It involves the linking of monomers with … Read more
