...Science and technology are the powerful engine to this century. Technology and sciences were designed by people to overcome problems and make life easier and more efficient. However efficiency and speed don’t always positively correlate with safety. In addition that they might result in destruction and damage. The damage of the scientific advancement in Oryx and Crake was demonstrated and portrayed in the pigoons, which are biological organ factories and as was mentioned in lecture they are made for xenotransplantation. This process grows an organ made of similar cells to humans and then transplant it in the patient. This view on animals makes us think of them unethically and ignore their great role in the ecosystem. Animals play an important...

...“Right step of Maintenance is the SOUL™ of efficiency” An ISO 900:2008 Certified Comp. BOILER-BASICS What is a Boiler? Boiler, also called STEAM GENERATOR, is an apparatus designed to convert a liquid to vapor. In a conventional steam power plant, a boiler consists of a furnace in which fuel is burned, surfaces to transmit heat from the combustion products to the water, and a space where steam can form and collect. A conventional boiler has a furnace that burns a fossil fuel or, in some installations, waste fuels. A nuclear reactor can also serve as a source of heat for generating steam under pressure. Boilers were built as early as the 1st century AD by Hero of Alexandria but were used only as toys. Not until the 17th century was serious consideration given to the potential of steam power for practical work. Denis Papin of France designed the first boiler with a safety valve in 1679; boilers were made of wrought iron; as the advantages of high pressure and temperature were realized, manufactures turned to steel. Modern boilers are made of alloy steel to withstand high pressures and extremely high temperatures. Most conventional steam boilers are classed as either fire-tube or water tube types. In the fire-tube type, the water surrounds the steel tubes through which hot gases from the furnace flow. The steam generated collects above the water level in a cylindrically shaped drum. A safety valve is set to allow escape of steam at pressures above normal operating pressure;...
