Sols can be defined as colloidal systems with solid as dispersed phase and liquid as dispersion medium. Lyophobic sol and Lyophilic sol are the only types of sols. Lyophilic sols commonly described as liquid loving sols have a greater affinity for solvent. These sols are prepared easily by shaking or warming the dispersion phase in … Read more
A Proportionate counter is an instrument for detecting and measuring the intensity of ionizing radiation. It is similar to a Greiger Mueller counter but operates at a lower potential difference such that the magnitude of the discharge is directly proportional to the number of gas molecules ionized by the detected particle. This may permit the … Read more
Gas solid chromatography and Gas liquid chromatography are both the main types of Gas chromatography. In both methods, either liquid or solid is used as a stationary phase whereas gas is used a mobile phase. Gas solid chromatography entails passage of a mixture of volatile compounds with differential migration through a column containing solid stationary … Read more
What Is logical Address? A logical address also referred to as a virtual address, is an address of something generated by the central processing unit (CPU) while a program is running. Usually, the operating system or some other programs uses base addresses as a measure to find addresses. In this case the base address refers … Read more
A covalent bond also referred to as a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electrons are pairs are referred to as shared pairs or bonding pairs and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent … Read more
What Are Loops? Looping in programming language is a feature which facilitates the execution of a set of instructions/functions repeatedly while some condition evaluates to be true. A program executes the sequence of statements many times until the stated condition becomes false. A loop consists of two parts, a body of a loop and a … Read more
Pi Bond & Sigma Bond A Pi bond is a covalent bond which is formed by the side-to-side overlap of two atomic orbitals. Each of these atomic orbitals has zero electron density at a shared nodal plane, passing through the two bonded nuclei. The same plane is also a nodal plane for the molecular orbital … Read more
What Are ZooPlankton? Zooplankton are a type of heterotrophic plankton that range from microscopic to large species. They are found within large bodies of water, including oceans and freshwater systems. Zooplankton community is composed of both primary consumers which eat free-floating algae and secondary consumers which feed on other zooplankton. Zooplankton can also be described … Read more
Photoperiodism refers to the response of plants to the lengths of dark and light periods. Many flowering plants (Angiosperms) use a photoreceptor protein such as phytochrome or crytochrome to sense changes in their environment as far night or day length is concerned, which they take as signals a to flower. Vernalization is the artificial exposure … Read more
Urethra is the vessels responsible for transporting urine from the bladder to an external opening in the perineum. It is lined by stratified columnar epithelium which is protected from corrosive urine by mucus secreting glands. The male urethra is a narrow fibromuscular tube that conducts urine and semen from bladder and ejaculatory ducts respectively to … Read more
