Benz[a]acridine was considered by previous IARC Working Groups in 1983 and 1987 (IARC, 1983, 1987). Since that time, new data have become available; these have been incorporated into the Monograph, and taken into consideration in the present evaluation. Benz[c]acridine was considered by previous Working Groups in 1972, 1983, and 1987 (IARC, 1973a, 1983, 1987). Since that time, new data have bec...

As a developing country with large population, China is facing the problems of energy resource shortage and growing environmental pollution arising from the coal-dominated energy structure. Biomass energy, as a kind of renewable energy with the characteristics of being easy to store and friendly to environment, has become the focus of China's energy development in the future. Affected by the ad...

Introduction: Although the psychological aspects of rhinoplasty have been fully investigated in the medical literature, the religiosity of rhinoplasty candidates has not been taken into consideration. Materials and Methods: In this cross-sectional study, the religious attitudes of 157 rhinoplasty candidates were compared with those of 74 subjects who had not requested rhinoplasty. A domestic v...

The use of space by predators in relation to their prey is a poorly understood aspect of predator-prey interactions. Classic theory suggests that predators should focus their efforts on areas of abundant prey, that is, prey hotspots, whereas game-theoretical models of predator and prey movement suggest that the distribution of predators should match that of their prey's resources. If, however, ...

We study the level and severity of asset poverty, the characteristics of asset-poor households, the trends and persistence of asset poverty, and the role of major lifetime events affecting transitions in and out of asset poverty. We find that, contrary to a sharp decline in the official measure of poverty, which is based on income, the asset poverty rate barely changed over the 1984–99 period a...

Demain, A. L. (Merck Sharp & Dohme Research Laboratories, Rahway, N.J.), I. M. Miller, and D. Hendlin. Production of extracellular guanosine-5'-monophosphate by Bacillus subtilis. J. Bacteriol. 88:991-995. 1964.-Wild-type Bacillus subtilis colonies were found to feed purineless mutants. A strain with high feeding capacity was selected for study, with a guanineless mutant of B. subtilis used as ...

We report high resolution simultaneous measurements of electrical conductance and force gradient between two sharp gold tips as their separation is varied from the tunneling distance to atomic-size contact. The use of atomically sharp tips minimizes van der Waals interaction, making it possible to identify the short-range metallic adhesion contribution to the total force.

this research is to survey the relationship between foreign policy of i.r.r. and perspective document in reaching regional superior power. for the first time, in this document, regional approach has been put forwarded. the concept of regional superior power in the document has been taken from two aims: reaching to upper place of scientific, technology, economics, and an effective constructing i...

The surgical treatment of rectal cancer includes radical resection techniques and local excision procedures. Radical resection techniques are still the golden standard in the management of rectal cancer, but the increased postoperative morbidity and mortality led to the idea that less traumatizing procedures of local excision may have the same oncologic results, in selected cases. Yet, the sign...
