Agricultural experts have recognized soils health problems like deficiency of micronutrients and organic matter‚ soil salinity and damage of soil structure. 4.

into a common [0-1] scale. The minimum 0 corresponds to the less desirable condition with regards to aquifer recharge with reclaimed water and 1 the most desirable condition. The cell values of all continuous numerical sub-criteria (e.g. slope‚ soil salinity and unsaturated zone depth) were rescaled using fuzzy linear membership functions. For categorical layers (e.g. soil texture‚ land use and geology) the categories were first grouped into classes according to their potential for aquifer recharge.

pushing the vehicle in the opposite direction. Although some working prototypes exist‚ MHD drives remain impractical. Ship propulsion An electric current is passed through seawater in the presence of an intense magnetic field‚ which interacts with the magnetic field of the current through the water. Functionally‚ the seawater is then the moving‚ conductive part of an electric motor. Pushing the water out the back accelerates the vehicle in the forward direction. The physics equation describing this

The Holocaust was one of the darkest times in history. During World War II the Nazi party was gaining power. Hitler believed that the Aryan race were superior. Hitler also believed the Jewish people were to blame for losing World War I. The Holocaust was a genocide of the Jewish. Jews were taken from their homes and taken to ghettos‚ which were crowded unsanitary housing. After living in uncomfortable conditions‚ they were moved to concentration camps. These camps weren’t made for people to survive

large amounts of the reefs systems being buried by sediment. Reefs are very delicate and need very precise conditions to live and grow‚ the amount of rain that is associated with intense low systems can flood the reef with fresh water and reduce the salinity levels. During the storms the turbidly of the water also increases so the sunlight cannot reach the coral reducing its ability to produce food. Tropical cyclone Larry (2006) showed that reefs could benefit from storms. The waves that were produced

epidermidis and E. coli were subjected to varying NaCl concentrations in order to test for the minimum and optimum salinities of individual bacterial species. Looking at the growth of E. coli under NaCl concentrations of 2‚ 5‚ 10‚ and 15%‚ the data collected showed optimal growth at lower concentrations‚ more specifically at 2%. Growth gradually decreased until no growth

proposals like iron fertilization tend to raise many uncertainties and risks. Phytoplankton‚ which includes microscopic marine plants and photosynthetic microbes‚ blooms naturally in the ocean. However‚ in seawater‚ there is only limited iron‚ an element these organisms need to grow‚ so by adding iron to seawater‚ it’s possible to make a man-made bloom. This bloom funnelled a significant amount of Earth-warming carbon down into the ocean’s depths‚ where it will remain sequestered for some time‚ unable to contribute

In the essays‚ he suggested the best way to distill seawater without the use of chemicals; this helped sailors in attaining proper drinking water at sea. He also explained the best methods to prevent tropical fevers‚ ways to get fresh water at sea‚ and other helpful dietary tips‚ which when adopted by the
