Access control is really a system enabling authorities to manage usage of areas and resources in a very given physical facility or computer-based information system. Access control is, in reality, perhaps the most common, everyday phenomenon. For example, a lock over a car door is basically a sort of access control. The PIN with a bank's ATM method is another way of access control. Even nightclub bouncers, waiting in front of the door, are another instance of (perhaps) a more primitive mode of access control. Using an access control mechanism is important when persons seek to secure confidential, important, or sensitive information and equipment.
Some algae species are 50% or more lipid oil by weight. This oil may be pressed from the algae and refined into diesel. The process for extracting algal oil, at its simplest level, resembles pressing an olive. Up to 75% from the oil might be squeezed from algae using a simple mechanical press. Hexane might be used being a solvent to raise extraction up to 95%. Once extracted, the oil is refined through transesterification. A catalyst including sodium hydroxide is combined with alcohol to make biodiesel and glycerol.
