Electrical transport measurements were made on single-crystal Sn nanowires to understand the intrinsic dissipation mechanisms of a one-dimensional superconductor. While the resistance of wires of diameter larger than 70 nm drops precipitously to zero at Tc near 3.7 K, a residual resistive tail extending down to low temperature is found for wires with diameters of 20 and 40 nm. As a function of ...

DDT indoor residual sprayings in the Province of Central Java, Indonesia, for the past 28 years are reoieuied in terms ofAnopheles aconitus resistance to DDT and incidences of malaria. DDT resistance by An. aconitus has continued to increase and spread since its first detection in Central Java in 1962. In most areas malaria transmission is perennial, which appears to be not interrupted by DDT r...

Imatinib has revolutionized drug therapy of chronic myeloid leukemia (CML). Preclinical studies were promising but the results of clinical trials by far exceeded expectations. Responses in chronic phase are unprecedented, with rates of complete cytogenetic response (CCR) of more than 40% in patients after failure of interferon-alpha (IFN) and more than 80% in newly diagnosed patients, a level o...

The effect of SiBCN powder on properties phenolic resins and composites was analyzed. Compared with resins, the thermal stability modified (the resins) by characterization thermogravimetric analysis (TGA) improved clearly. It found X-ray photoelectron spectroscopy (XPS) that reactions between pyrolysis product were main factor increased residual weight. TGA static ablation a muffle furnace used...

background: obesity and overweight are accompanied with insulin resistance markers and diagnosed as a metabolic risk factor in prevalence and develop the asthma severity. regardless of biological role of inflammation markers in asthma, the effective mechanisms in relation to obesity and asthma are not fully understood. methods: this study investigates the relationship between insulin resistance...

using of microorganisms to remove industrial pollutions of environment is an efficient methodthat mimics natural process and decrease remediation cost. in this study, 450 actinomycete strains wereisolated from high metal content soils in iran. heavy metal salt solutions in different concentrations were usedto isolate the resistant strains. 40 resistant actinomycetes which they showed highly res...

introduction: retreatment is performed in teeth with unsuccessful root canal therapy or persistent apical lesion. the most important factor for achieving successful retreatment is thorough cleaning and reshaping. niti files and rotary instruments are widely used for the removal of obturatants. this study compared the ability of mtwo and d-race retreatment systems to remove residual gutta-percha...

Low temperature carburizing (LTC) treatment improves surface hardness and wear resistance of the austenitic stainless steels without reducing their corrosion resistance. Surface hardness over 1000 Vickers and compressive residual stresses whose modulus exceeds 1500 MPa are usually achieved in the carburized layer, thanks to the formation of the so-called “S-phase”, a carbonsupersaturated austen...

BACKGROUND We investigated virological response and the emergence of resistance in the Nevirapine or Abacavir (NORA) substudy of the Development of Antiretroviral Treatment in Africa (DART) trial. METHODS Six hundred symptomatic antiretroviral-naive human immunodeficiency virus (HIV)-infected adults (CD4 cell count, <200 cells/mm(3)) from 2 Ugandan centers were randomized to receive zidovudin...
