Violence and Mental Illness

General population. Swanson, et al.,5 noted that 3.7 percent of the general US population perpetrates one or more violent acts each year, and the lifetime prevalence of aggressive behavior in the community may be as high as 24 percent. According to the Centers for Disease Control (CDC), 17,357 homicides occurred in 2004, making it the 15th leading cause of death and yielding a death rate by

Corrosion of Steel Reinforcement in Concrete- Causes …

During the setting of concrete, cement begins to hydrate, this chemical reaction between cement and water in the concrete causes calcium hydroxide to be formed from the cement clinker. This ensures the concrete’s alkalinity, producing a pH value of more than 12.6 which renders the steel surface passive.

Calcium is denser than group 1 metals so sinks and …

Aluminum – expert written, user friendly element …

There is more aluminum in the Earth’s crust than any other metal. At about 8 percent, aluminum is the third most abundant element in our planet’s crust, behind oxygen and silicon. Despite its high abundance, in the 1850s aluminum was more valuable than gold. In 1852 aluminum was priced at $1200 per kg and gold was $664 per kg.
