This study investigates whether female and male full-time dental faculty members in U.S. dental schools differ in their workplace experiences and perceptions. A questionnaire was mailed to the 2,203 U.S. members of the American Dental Education Association (ADEA) in May 2001, and 870 faculty members responded (response rate: 40 percent). The data of the 738 full-time employed faculty members (f...
The prevalence of morbid obesity is increasing at an alarming rate worldwide and is becoming a major public health problem in the United States. Because of the failure of conventional weight loss therapies for morbid obesity, the National Heart, Lung, and Blood Institute of the National Institutes of Health (NIH) recommends surgical therapy as the only intervention associated with long-term suc...
low cereal and legumes yields and their rwp index are mainly due to poor distribution of rainfall and poor agronomic management practices. rainfed barley yield and rain water productivity (rwp, defined as rainfed grain yield divided by the total crop season annual rainfall water) in the dry farming are considerable by topography and latitude. yield data, rainfall, altitude and latitude of 182 p...

International commentators including the IMF and the ADB have commended our economic management. Four years of consecutive growth is a performance that was difficult to achieve in the past. Not only have we achieved growth, the growth rates have been generally higher. The average growth rate in four years is over 4 percent, compared to 3 percent average growth from 1987 to 1999. Moreover, we ha...
An efficient chiral squaramide-catalysed enantioselective Michael addition of pyrazolin-5-ones to nitroalkenes has been developed. This reaction afforded the chiral pyrazol-3-ol derivatives in high to excellent yields (up to >99%) with high enantioselectivities (up to 94% ee) for most substrates under very low catalyst loading (0.25 mol%). This catalytic asymmetric reaction provides valuable an...
BACKGROUND Substitution can be operationalized as the conscious choice to use one drug (legal or illicit) instead of, or in conjunction with, another due to issues such as: perceived safety; level of addiction potential; effectiveness in relieving symptoms; access and level of acceptance.
