The science of the total environment

Physical Review B

There can be little doubt that the Monte Carlo method for semiconductor device simulation has enormous power as a research tool. It represents a detailed physical model of the semiconductor material(s), and provides a high degree of insight into the microscopic transport processes. However, if the authority ascribed to Monte Carlo models of devices at 1/spl mu/m feature size is to be maintained for devices below O.1/spl mu/m, modelling of the fundamental physics must be further improved. And if the Monte Carlo method is to be successful as a semiconductor device design tool, the device model must be made more realistic. Success in the industrial sector depends on this, but also on achieving fast run-times optimisation - where the scope and need for ingenuity is now greatest.

A machine for magnetic water treatment is designed and its application on the ions contained in water has been investigated to examine the effect of magnetic water on concrete parameters. Strength parameters of concrete have been studied for more than 104 concrete samples, including the non-magnetic samples (made by ordinary water) and magnetic samples (made by magnetic water), with slump and compressive strength experiments. Based on slump experiments, magnetic samples were 7 centimetres more than non-magnetic group and the average compressive strength of samples made by magnetic water was 23% more than that of samples made by ordinary water. The experimental results show the advantages of magnetic samples in concrete industry because of increase in plasticity, the efficiency and quality of concrete boosts in comparison with nonmagnetic samples.

The Effect of Magnetic Water on Strength Parameters of Concrete

4 Abstract: We have investigated the effect of magnetic water treatment on growth and quality improvement of poultry. Some of poultry characteristics have been studied for about 100 chicken samples, including the nonmagnetic samples (drinking by ordinary water) and magnetic samples (drinking by magnetic water). Based on the results of our experiments, magnetic samples have about 200 gr meat more than the nonmagnetic samples. The magnetic samples have also shown other advantages like, increasing in meat fat ratio, livability and European production efficiency, a decrease in mortality, sick case and feed reduction and a high quality of final product. Statistical calculations are in fair agreement with our experimental results.
