What Is Transistor? A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Transistors are one of the basic building blocks of modern electronics. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one … Read more
What Is Stain? Staining is a technique used to enhance contrast in samples, generally at the microscopic level. Stains and dyes are frequently used in histology (the study of tissue under the microscope) and in the medical fields of histopathology, hematology, and cytopathology that focus on the study and diagnoses of disease at a microscopic level. Stains may be used to define biological tissues (highlighting, for example, muscle fibers or connective tissue), cell populations (classifying different blood cells), or organelles within individual … Read more
What Is Pipe Flow? The pipe flow is a type of flow that occurs within a closed conduit. There is no free surface in this type of flow and also does not exert direct atmospheric pressure like open channel flow, but exerts hydraulic pressure on the conduit. In other words, in closed pipes, the flow … Read more
Oxidation and reduction reactions occur simultaneously and they are termed REDOX reaction. REDOX can be described a type of chemical reaction in which the oxidation states of atoms are changed. REDOX reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation (lose electrons) while … Read more
What Is Acetal? Acetals are geminal-diether derivatives of aldehydes or ketones, formed by reaction with two equivalents (or an excess amount) of an alcohol and elimination of water. Ketone derivatives of this kind were once called ketals, but modern usage has dropped that term. It is important to note that a hemiacetal is formed as … Read more
Fluorescence and phosphorescence are two mechanisms that emit light or examples of photoluminescence. However, the two terms don’t mean the same thing and don’t the same thing and don’t occur the same way. In both fluorescence and phosphorescence, molecules absorb light and emit photons with less energy (longer wavelength), but fluorescence occurs much more quickly … Read more
Glucose Glucose is a simple sugar with the molecular formula C6H12O6. Glucose is the most abundant monosaccharide, a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight, where it is used to make cellulose in cell walls, the most abundant carbohydrate in the world. Though glucose is called a simple … Read more
What is Git? Git is an open-source version control system that is used to efficiently manage projects ranging in size from small to huge. During software development, this software keeps track of changes in a set of files and can help coordinate work between programmers working on source code together. Linus Torvalds founded it in … Read more
Stars Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Many stars occur in pairs, multiple systems, or star clusters. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night, but due to their immense distance from Earth they … Read more
What Is Diabetes mellitus? Diabetes mellitus commonly referred to as Diabetes is a group of metabolic disorders characterized by a high blood sugar level over a prolonged period of time. This type of diabetes is generally due to either the pancreas not producing enough insulin or the cells of the body not responding properly to … Read more
