Amwoga KhalwaleWhat Is Nitrification? In this process, the ammonia is converted into nitrate by the presence of bacteria in the soil. Nitrites are formed by the oxidation of Ammonia with the help of Nitrosomonas bacterium species. Later, the produced nitrites are converted into nitrates by Nitrobacter. This conversion is very important as ammonia gas is toxic for plants. … Read more

What Is Plasticizer? Any substance added to a polymer material that can increase the plasticity of a polymer is referred to as a plasticizer. Plasticizers make plastics elastic, extensible, flexible and plastic at low temperatures. Plasticizers are produced by reaction of an alcohol with an acid such as adipic acid, phthalic anhydride and so forth. … Read more
Encoder In Digital Logic An Encoder is a combinational circuit that performs the reverse operation of Decoder. It has maximum of 2n input lines and ‘n’ output lines, hence it encodes the information from 2n inputs into an n-bit code. It will produce a binary code equivalent to the input, which is active high. Therefore, … Read more

What Is Star Connection? In star connection, one end of all the three wires are connected to a common point in the shape of Y, such that all the three ends of the three wires form the three phases and the common point forms the neutral. Star connection is preferred for long distance power transmission … Read more
What Is A Virtual Function? A virtual function is a member function within the base class that we redefine in a derived class. It is declared using the virtual keyword. When a class containing virtual function is inherited, the derived class redefines the virtual function to suit its own needs. Virtual function ensure that the … Read more
Grafting and budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant. Grafting and budding are the most widely used vegetative propagation methods. In grafting, the upper part (scion) of the plant grows on the root system (rootstock) of another plant whereas … Read more
