A referee makes recommendations to the judge or court that appoints the referee but generally does not issue enforceable orders. A referee generally cannot render judgment in a case. The referee's general duty is to provide a report to the appointing judge on the issues of fact or law that prompted the referee's appointment.
Autoclave Overview. Learn the purpose and limitations of autoclaves, types of cycles, and procedures for safe and effective autoclaving. Purpose. Autoclaving, sometimes called steam sterilization, is the use of pressurized steam to kill infectious agents and denature proteins. This kind of wet heat is considered the most dependable method of sterilizing laboratory equipment and decontaminating biohazardous waste.
The sand, inert when used in dense concrete, behaves as a pozzolan in the autoclave due to the high temperature and pressure. Autoclaved aerated concrete is cured in an autoclave-a large pressure vessel.In aircrete production the autoclave is normally a steel tube some 3 metres in diameter and 45 metres long. Steam is fed into the autoclave at high pressure, typically reaching a pressure of 800 kPa and a temperature of 180 AÂ°Ã¢. cutoclaved aerated concrete is easily cut to any required shape. Aerated concrete blocks also have good acoustic properties and it is durable, with good resistance to sulfate attack and to damage by fire and frost. The low density is achieved by the formation of air voids to produce a cellular structure.
