The RNA viruses which are retroviruses enters CD4 cells by binding to a specialized site which is receptor on a body cell. Then, the virus loses its protective coat and releases RNA, its genetic material , and an enzyme known as reverse transcriptase . The enzyme reverse transcriptase contained inside the viral core to convert their RNA into a form that can enter the host cell’s nucleus and incorporated with the cell’s genetic material. Hence , it build DNA strands based on the RNA strand and it

Definition: Reverse osmosis (RO) is a membrane-technology filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective," this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components

Financial analysis 2. Reverse merger One of the key words in this case is “reverse merger”. According to historical statistics, it is shown that the reverse merger one time had been a boom in the market all over the world. But, here comes the question, what is a reverse merger? Generally speaking, a reverse merger, also known as a reverse takeover or reverse IPO, is a simpler and time-shorter method for private companies to go public than common IPO. In a reverse merger, investors of the

from seawater. Seawater has been strongly transformed to pure drinking water for personal drinking. Seawater properties are primarily salt. The eradication of the physical and chemical properties shift seawater into a current recyclable unit. Reverse osmosis and multi flash distillation are two approaches that a few countries are using to turn seawater into drinking water, but there are some risks and assets to this procedure that individuals should examine. Physical and Chemical Properties

water evaporates, and this steam flows into the tubes of the next stage, heating and evaporating more water. Each stage essentially reuses the energy from the previous stage), and multi-stage flash evaporation. Or membrane technologies which include: reverse osmosis, electrodeionisation, and electrodialysis.

practiced for more than seventy years. Although the consumption of energy and costs are generally higher than the reverse osmosis and the electrical processes, it currently provides most of the processed drinking and processed water. The most common method for desalination is reverse osmosis. The reverse osmosis membrane is designed only to allow water to pass through the dense layer. “Reverse osmosis is a process where pressure is used to push the water solution through a membrane, with the membrane

Reverse osmosis is nothing new as a water treatment method. In fact, it has been in use for more than 40 years. It was originally used as a less expensive method of desalinization. In many parts of the world, the lack of fresh water is a serious issue, so the invention of reverse osmosis has helped many people around the world. Now people in parts of the world that were dying for lack of clean water are able to get plenty of water for drinking and cleaning. It didn't take people long to realize

Class and Discrimination in Business In America, class is something that is not important, most of us are middle-class and we are continuously moving up the economic ladder, because we all have an equal opportunity to succeed. I would certainly object to these commonly held beliefs. . In “Class in America-2003,” first published in Race, Class, and Gender in the United States: An Integrated Study, Mantsios thoroughly persuades his readers that Americans avoid talking about class, because there
