plastics, one of the most abundant materials in the world today, are one of the main sources of pollution. people’s perception of using and disposing plastic bags is primordial as they tend to be a major part of household solid waste. this study aims to determine community’s perception of usage and disposal of plastic bags in eastern ethiopia. a quantitative cross-sectional study has been condu...

background: a substantial part of the public’s natural radiation dose is due to the inhalation of radon gas. most of the exposure occurs indoors where the airborne concentration of radon and its decay products is usually higher than outdoors. materials and methods: radon activity concentration has been measured twice in 50 classrooms in 5 levels (10 each) during summer and winter using solid-st...

Aluminum alloys exhibit recrystallization kinetics that vary strongly with composition. The conventional understanding is that certain alloying elements, e.g. chromium, retard grain boundary motion due to the formation of fine dispersions of second phase particles, giving rise to particle drag of boundaries. There is countervailing evidence, however, that suggests that solute drag provides a st...

BACKGROUND Actually, there are 2 main methods to obtain stromal vascular fraction (SVF): enzymatic digestion and mechanical filtration; however, the available systems report heterogeneous and sometimes not univocal results. The aim of this study is to evaluate different procedures for SVF isolation and compare their clinical efficacy in the treatment of soft-tissue defects in plastic and recons...

Recently, 211At has received increasing attention as a potential radionuclide for cancer radioimmunotherapy. It is a α-particle emitter, which is extremely effective against malignant cells. We demonstrate a method to verify the efficiency of 211At-labeled trastuzumab antibodies (211At-trastuzumab) against HER2 antigens, which has not been determined for radioimmunotherapy. A CR-39 plastic nucl...
