Background information Daphnia Magna is an arthropod that can grow up to 5 mm. It is a filter feeder meaning it feeds off of suspended particles in the water. Daphnia can consume particles that range from 1µ to 50µ. The heart of Daphnia is located dorsally meaning it’s located in the back. The heart rate of Daphnia can range due to many variables‚ one being temperature.

Fresh Water Cooling System Introduction Although there is an abundance of free sea water available‚ marine diesel engines do not use it directly to keep the hottest parts of the engine cool. This is because of the corrosion which would be caused in the cooling water spaces‚ and the salts which would be deposited on the cooling surfaces interfering with the heat flow. Instead‚ the water circulated around the engine is fresh water which is then itself cooled using sea water. This fresh water is

Once known as the number one agricultural county in the nation‚ Los Angeles County houses nearly 10 million residents. This means the demand for consumable water is high‚ and with this demand comes depletion. Many areas of the Central and West Coast Basins are experiencing ground water depletion‚ which has resulted in an intrusion of saltwater in coastal aquifers‚ “natural filters that trap sediment and other particles (like bacteria) and provide natural purification of the ground water flowing through
