Illicit Drug Use in Pregnancy COM 220 August 1st‚ 2010 Illicit Drug Use in Pregnancy Studies in 2008 have shown that the amount of babies born to drug addicted mothers has almost doubled since 2003. Pregnant mothers have been using drugs during pregnancy for thousands of years without knowing the effects they can have on their unborn baby. Even though some people claim that illicit drugs used by pregnant mothers cause no harm to the fetus‚ there have been studies that show otherwise. Cocaine

Chapter I THE PROBLEM Introduction Rubber is an elastic hydrocarbon polymer which occurs as a milky emulsion (known as latex) in the sap of a number of plants but can also be produced synthetically. The major commercial source of the latex used to create rubber is the Para rubber tree‚ Hevea brasiliensis (Euphorbiaceae). This is largely because it responds to wounding by producing more latex. Other plants containing latex include figs‚ euphorbias and the common dandelion

Structural Effects on Stability and Reactivity. Organic Chemstry Laboratory Structural Effects on Stability and Reactivity Introduction The concepts of stability and reactivity are fundamental to understanding chemistry. In this chapter we consider first the thermodynamic definition of chemical stability. We then consider chemical kinetics (Section 3.2) and how it can provide information about reactivity. We also explore how structure influences stability and reactivity. We want to learn how

The process of hydraulic fracturing involved hundreds and hundreds of other chemicals‚ with a handful of them being toxic to humans: including benzene‚ toluene‚ xylene and ethylbenzene. Since leaky may be an issue due to the research that was done on methane contamination of water sources‚ there is also the possibility that the number of other chemicals in the fracking process have the potential to make
