Betz law Albert Betz, was a German physicist who lived between 1885 and 1968 who raised a law that established wind use through kinetic energy delimiting the maximum point in which this could be taken advantage of. As we see we are...

chemical change in tissues. When hydrogen atoms begin to take their initial alignment, a process called ‘precession’ begins. This produces different energy emissions that vary depending on the type of tissue is being explored. The NMR captures these energy variations, and creates based on the information obtained, different images of the interior of the body. The protons return to their state of alignment in different speeds, depending on the type of body tissue, so the scanner can distinguish between several different types. The scanner can be adjusted depending on the type of tissue to be studied, through additional magnetic fields, obtaining three -dimensional images that can be seen from...

chemical waste, oil, plastics, organic remains, etc., are some of the main pollutants of this essential resource for life.

Developing Landing at the local level, drought in the southern region of the Dominican Republic has caused it to be necessary to store large amounts of the precious liquid in order to subsist. A wide range of diseases which are transmitted by water have been viable due to the mismanagement of water resources. The livestock sector, specifically the...
chemical treatment to water. When adding ozone, through an electric field, oxygen molecules of the water are transformed from O2. With this oxidizing effect, the action of viruses, bacteria and fungi is slowed down. It also manages to do a more rigorous work than that of chlorine, which disinfects to a lesser extent. It is mainly used in hospitals, food packaging plants where maximum hygiene and disinfection is required. Water purifier by ultraviolet light. conclusion Its great advantage is that they do not use any chemical, avoiding altering the molecular composition of the water. These purifiers use ultraviolet lamps. The UV ray frequency has great germicidal power, capable of disintegrating...
chemicals. Roofs Based on what indicates the rules, the ceilings have to comply with the same standards as on the walls, regarding the cleaning and disinfection class in the same way it has to be designed to facilitate sanitation. They must be built with a type of industrial thermal insulator called Sandwich panel, which are assembled with each other, they have a smooth surface. The finishing materials that are used can be metallic such as steel, pre -fold or stainless, galvanized, and other material such as resin and melanin. As filling, polystyre or polyurethane or rock wool can be used. The roofs for white rooms must also be inert to microorganisms and be resistant to the action of...
