maize genotypes were screened for host resistance and seed treatment chemicals were evaluated in field to manage fusarium ear rot complex of maize at high- and mid-hill environments in nepal during 2003 and 2004. seven popular maize genotypes along with a susceptible check were used in the host resistance study. the maize genotypes adopted from exotic sources, manakamana-3 and deuti, performed ...

ti-6al-4v titanium alloy has great application in medicine and military industries due to its capabilities, namely high strength to weight ratio and corrosion resistance. in the current research, the effect of aging treatment on microstructure and wear behavior of ti-6al-4v titanium alloy was investigated. pin on disk wear test was applied to assess the wear behavior. specimens were first solut...

Deep cryogenic heat treatment is assumed as a supplementary heat treatment performed on steels before the final tempering treatment to enhance the wear resistance and hardness of the steels. In this study, the effects of the deep cryogenic heat treatment on the wear behavior and corrosion resistance of the 1.2080 tool steel were studied using the wear testing machine and polarization and impeda...

introduction: wastewater treatment plants are important hotspots for the spread of  antibiotic resistance genes to the environment.  the aim of this study identification of relevant antibiotic resistance genes  in raw  and final effluent of municipal wastewater treatment and also determination of effects of different wastewater treatment process on removal/reduction of these pollutants. materia...

Any pathogen population sufficiently large is expected to harbor spontaneous drug-resistant mutants, often responsible for disease relapse after antibiotic therapy. It is seldom appreciated, however, that while larger populations harbor more mutants, the abundance distribution of these mutants is expected to be markedly uneven. This is because a larger population size allows early mutants to ex...
