A fire occurred in a transformer vault that supplied power to a pesticide storage warehouse. The warehouse also caught fire. The warehouse was located in a rural area. There was a river adjacent to the warehouse that was the source of drinking water for a town downstream of the warehouse. The chemical products that were used in the transformer and the chemicals that were stored in the warehouse were all industrial strength and were supposed to be handled with extreme caution. All of these chemicals

BCR : the importance of nitrogen . I suspect that your instructor had some elements that he/she explained were critical to "a Well Designed Investigation." If I were you‚ I would get those out to start with so that you can make sure that you include all in your answer. 1. Probably they include negatives and‚ if possible‚ positive controls. Is your negative control a test plant that is planted in a pot with no legume planted in the pot? Do you have any other negative controls? How about positive

n Class VI you learnt that food is essential for all living organisms. You also learnt that carbohydrates‚ proteins‚ fats‚ vitamins and minerals are components of food. These components of food are necessary for our body and are called nutrients nutrients. All living organisms require food. Plants can make their food themselves but animals including humans cannot. They get it from plants or animals that eat plants. Thus‚ humans and animals are directly or indirectly dependent on plants. I 1

The Gulf of Mexico Dead Zone The gulf of Mexico’s dead zone is only getting worse doing a great deal of damage to the U.S. economy. The issue in the Gulf of Mexico is the dead zone that has started occurring since 1972 and is only increasing in size. The Gulf of Mexico supplies the U.S. with 72% of their income shrimp 66% of oysters and 16% of fish (Philpott‚ 2013). If the dead zone does not decrease in size fisherman and costal workers will be largely impacted

H2O The feed of 90% Ethanol is kept in a storage tank with an air vent. Tank blanketing is used in the storage tank with Nitrogen gas. This is to prevent contamination of the feed. Nitrogen tank blanketing will reduce the oxygen level in the tank‚ and thus reduce the risk of fires and/or explosions posed by Ethanol‚ which is a volatile and combustible substance. The Nitrogen gas will exit from the air vent‚ preventing it from flowing into the process. The feed is pumped from a pressure of 1

They convert an estimated 90% of the hydrocarbons‚ carbon monoxide‚ and nitrogen oxides produced into less harmful compounds. However‚ catalytic converters are less efficient when used with diesel engines‚ which run colder than gasoline engines. Catalytic converters work best at higher temperatures. Catalytic converters are
