A cable tray is a subset of cable management systems. Cable trays are used to provide mechanical support and protection to electrical cables or wires that are used for power distribution and data communication within a building. They can support various types of wires — high-voltage power lines, power distribution cables, sensitive control wiring, telecommunication wiring, and optical cables. They are usually placed above false ceilings and in trenches. Cable trays are particularly useful in situations where changes to a wiring system are anticipated. New cables can be easily installed by laying them in the tray, instead of pulling them through a pipe.

The cable conduit systems form a subset of the cable management systems used for protection and routing of electrical wires/cables. These are tubular structures designed to carry wires and cables. The conduit system comprises tubing (conduit) and the required fitting components such as elbows, clamps, connectors, and others. It can be made up of metal, plastic, or fiber. It offers several competitive advantages over conventional wiring systems such as simpler and safer wirings, permits easier and frequent alterations in the wiring system, and provides protection even in damp and hazardous locations.

The past century has seen the dominance of fossil fuels as the chief source of energy for the sustenance of the global economic machinery. Among these fuels, the one commodity which has controlled almost all the aspects of the energy business is crude oil. Crude oil is defined as a mixture of compounds composed primarily of carbon and hydrogen in varying proportion, with the presence of inorganic compounds such as nitrogen, Sulphur, and metals such as vanadium, mercury. The crude oil, in the discussion, is found in specific rock formations, called reservoirs, in the earth's crust. The depth at which these reservoirs occur can vary significantly, from pools which flow up to the surface to almost 15,000 meters' underground. The method which is employed to get to these reservoirs of black gold is through drilling the surface till we reach the pre-defined depth.

Bromine is a halogen and a non-metallic chemical element. It is highly toxic and extremely reactive. It requires precautions and proper handling. At room temperature, bromine is a reddish-brown thick liquid. Elemental bromine is extracted from salt lakes, seawater, and underground brine wells. Bromine is used in many inorganic and organic compounds. It cannot be substituted by other materials, without the properties of the compound changed. However, few organic bromine compounds can be substituted by few products with completely different chemistries.

One of the aspects of modern life that is considered as an essential by men and women is appearance. The desire to look presentable has led to the notable growth in the cosmetology industry. Originally, cosmetic surgery evolved from the reconstructive procedures and as a result, some of its techniques are similar whether they are used for reconstructive or cosmetic purposes. For instance, in various reconstructive procedures, breast implant is a procedure used to gain normal appearance after mastectomy. However, it has a much wider application in cosmetic technique to streamline the body shape.
