Polymorphism means ability to take more than one form. Polymorphism is considered as one of the important features of Object Oriented Programming. In C++ polymorphism is mainly categorized into two types, Compile time polymorphism (Static) or (Dynamic) Runtime polymorphism. In dynamic polymorphism, the response to a function is determined at the run-time whereas in static … Read more
What Is Amine? In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia, wherein one or more hydrogen atoms have been replaced by substituent such as an alkyl or aryl group. Sometimes amines in which both types of substituent are … Read more
What is Pollination? Pollination is the transfer of pollen from the male (anther) of a flower to the female part (stigma) of the same or different flower. Pollen grains contain the male gametes and are present in the anthers of the flower. Pollination is usually the first process of sexual reproduction in flowering plants. There … Read more
What Is A Travelling Wave Tube? A travelling wave tube (TWT) is a specialized vacuum tube that is used in electronics to amplify radio frequency (RF) signals in the microwave range. The TWT belongs to a category of ‘’linear beam’’ tubes, such as the Klystron, in which the radio wave is amplified by absorbing power … Read more
What Is Solar Eclipse? A solar eclipse occurs when the moon gets between Earth and the Sun and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the Sun and Earth and its shadows fall upon Earth’s surface. … Read more
PAN( Personal Area Network) PAN stands for Personal Area Network. It is sometimes referred to as Wireless personal Area Network (WPAN). It’s a network covering a very small area, typically a small room. It enables computer devices to communicate with other nearby computers and exchange information and data. Devices in one PAN network can establish … Read more
Transpiration is the process in which plants lose water in the form of moisture or water vapor. Parts of plant like stem, small pores on leaves and flowers evaporate the water to the atmosphere. 90% of the transpiration occurs through foliar surface or surface of leaves. Types of transpiration include: stomatal, lenticular and cuticular transpiration. … Read more
What Are Lenticels? Lenticels are one of the many raised pores in the stem of a woody plant that allows gas exchange between the atmosphere and the internal tissues. Usually, lenticels consist of large intercellular spaces in the periderm, especially in secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering … Read more
Batch Fermentation (Batch Culture) Batch fermentation is the simplest mode of fermentation; it is made up of a mechanically stirred vessel with other accessories such as a gas sparger and a heating/cooling jacket. It is also widely used in biological industry, including microbial fermentation, cell metabolism and production of products. In batch fermentation, substrate and … Read more
An image function f(x,y) must be digitized both spatially and in amplitude in order to become suitable for digital processing. Typically, a frame grabber or digitizer is used to sample and quantize the analogue video signal. Therefore, in order to create an image which is digital, we need to convert continuous data into digital form. … Read more
