  • Cognitive radio is a hot research area for future wireless communications in the recent years. In order to increase the spectrum utilization, cognitive radio makes it possible for unlicensed users to access the spectrum unoccupied by licensed users. Cognitive radio let the equipments more intelligent to communicate with each other in a spectrum-aware manner and provide a new approach for the co-existence of multiple wireless systems.

  • More recently, a QSAR (Quantitative Structure Activity Relantionship) investigation was carried out on a series of nostoclide analogues presenting the general structure (43) to correlate molecular descriptions with their in vitro biological activity (the ability to interfere with ligh-driven reduction of ferrycianide by isolated spinach chloroplasts thylakoid membranes). The results of this investigation suggested that the degree of inhibition efficiency of this class of compounds is intimately associated with their polarity (Teixeira et al, 2009).

  • Ground level ozone also interferes with the ability of plants to produce and store food. It damages the leaves of trees and other plants, and contributes to a reduction in crop productivity, because the plants are more vulnerable to disease, pests, and harsh weather. Carbon monoxide (CO) is also a threat to the air we breathe. CO is formed when the carbon in fuel is not burned properly. The largest factor of CO emissions is automobiles. Cars, trucks, and buses account for 56% of the Earth’s carbon monoxide emissions. CO is...
