Are cell Phones a Health Hazard? With the increasing of mobile phones’ functions‚ people rely more and more on them. The lower price also enables the mobile phone to become people’s daily necessity. Now even many students have their own mobile phone. People began to worry about the cell phone which will do harm to our health. But why people become worried about that? There are some speculates that cell phone might potentially threaten human being’s health. Mobile phones can emit radiofrequency

warming is a natural cause. The Earth was heating long before humans were emitting large amounts of greenhouse gases and even before humans were on planet Earth. Since humans were not alive during the period after the ice age (known as the post-ice age era)‚ then the heating of the Earth to melt the ice does not put humans at fault. Global warming is naturally caused by natural emission of greenhouse gases‚ Earth’s heating and cooling system‚ and other planets heating without human life on them. The Earth

calculating the water of crystallization for the unknown hydrate salt. A hydrate salt is composed of anions (-) and cations (+) surrounded by a fixed number of water molecules‚ called water of crystallization. The hydrate decomposes upon heating and produces an anhydrous salt. After finding the formula mass of the hydrate by adding the amu ‚ we can calculate the percent of water in the hydrated salt by comparing the mass of the water of crystallization to the mass of the hydrate salt.

CHAPTER I 1. Fuzzy control Fuzzy control is a practical alternative for a variety of challenging control applicationssince it provides a convenient method for constructing nonlinear controllersvia the use of heuristic information. In a sense fuzzy systems can be “trained” and can “learn” how to perform throughout a control task and are considered as intelligent control system. Fuzzy control system design is based on empirical methods‚ basically a methodical approach to trail-and-error. The
