Oxidative stress plays a significant role in noise-induced hearing loss (NIHL), as it largely participates in the mechanisms that underlie cell death after noise exposure and lead to sensorineural hearing loss. Many antioxidant drugs have been tested to prevent NIHL. We present three molecules with antioxidant properties (vitamin E, idebenone, N-L-acetylcysteine) that have been studied in our laboratory, and compare their protective effects. We induced acoustic trauma in treated guinea pigs,...

Diversity of the engineering workforce begins with addressing the diversification issues in the education of engineers. The author describes some of the issues related to diversifying engineering education, which include not only the diversification of students and faculty but also the curriculum. She suggests that special attention be paid to the doubly underrepresented group—the female engineering student of color. She concludes that such diversification would benefit both female and male engineering students.

Over the next few decades the production has to be doubled to respond to the food demand of a growing population. On the other side the natural resource base for agricultural production is showing increasing signs of degradation. These problems are even more pronounced in Africa. In the past highly intensive agricultural production took a heavy toll on the environment, which was accepted as unavoidable collateral damage, while agriculture which was more respectful to the environment was less...
