Amwoga Khalwale A database server is the key to solving the problems of information management. In general, a server must reliably manage a large amount of data in a multi-user environment so that many users can concurrently access the same data. All this must be accomplished while delivering high performance. A database server must also prevent unauthorized … Read more
Homosporous Pteridophytes Hemosporous life occurs in nearly all bryophytes and in most pteridophytes (lower vascular plants). It is characterized by morphologically identical spores that germinate to produce bisexual (both male and female) gametophytes in pteridophytes but either bisexual or more usually, unisexual (either male or female) gametophytes in bryophytes. Each mature gametophyte bears gametangia (sex … Read more
The classification of organisms is the systematic grouping of living things based on characteristics, hierarchical, or phylogenetic relationships. It is one of the major aspects of taxonomy. Organisms are investigated in terms of their morphology, anatomy, physiology, evolution, behavior, development, and genetics in order to find out relationships between and among them. They are then classified … Read more
What Is Labor? Labor also referred to as childbirth is the process of the baby leaving the uterus (womb). Labor is characterized by regular contractions that cause your cervix to change. Contractions are when the muscles of the uterus get tight and then relax. Contractions help to push the baby out of the uterus via … Read more

Each pixel is actually a very small square that is assigned a color and then arranged in a pattern to form the image. A bitmap image is a grid made of rows and columns … Read more
Hydrocarbons are compounds that are made up of atoms of carbon and hydrogen exclusively. The unique nature of the carbon ensures that it shares a strong covalent bond with hydrogen. Since carbon atoms will make long chains with relative ease, hydrocarbons can be very big molecules linking even hundreds of atoms. Examples of hydrocarbons include … Read more
What Are Polarized Light? A light wave is an electromagnetic wave that travels through the vacuum of outer space. Light waves are produced by vibrating electric charges. More importantly, light waves are transverse, that is, the vibrating electric vector associated with each wave is perpendicular to the direction of propagation. Polarized light waves are light … Read more
Polar Covalent Bonds Polar covalent bonding is a type of chemical bonding where a pair of electrons is unequally shared between two atoms. In other words, the distribution of electrons around the molecule is no longer balanced. This is due to one of the elements having a higher electronegativity than the other. Atoms with high … Read more
Surveying is generally described as methodology of making scientific measurements on or above the surface of earth with the objective of determining points so as to produce a plan or map. Surveying is used widely in almost all civil engineering projects such as construction of building, bridges, reservoirs, dams, railways, roads, irrigation projects etc. Primarily, … Read more
