extended-spectrum β-lactamase (esbl)-producing enterobacteria has become a considerable global concern because of their potential dissemination in humans, in domestic animals, wildlife and the environment. the present study aimed to explore the esbl producing  enterobacteria in aquatic sources of bangladesh as the water may be the potential source of dissemination of this alarming antimicrobial...

The calibration of a catheter-based system to be used for therapeutic radiation treatment to prevent restenosis following interventional coronary procedures is described. The primary dosimetry was performed ionometrically using an extrapolation chamber equipped with a 1-mm diameter collecting electrode to measure absorbed dose in tissue equivalent plastic at a depth of 2 mm. These results are c...

the activity concentration of gross alpha and gross beta particles in four samples of borehole drinking water consumed in ibrahim badamasi babangida university (ibbu), lapai, niger state-nigeria was measured, using a portable single channel gas free proportional counter (mpc2000b-dp) detector. this study focused on cancer related problems and the bio-data of the environment was discussed as wel...

Dose rates in air and at various depths in tissue produced by concentrations of natural isotopes in the ground are calcu lated for both beta and gamma radiation. Calculated gonadal "screening factors" are within k$ of the experimental values reported by the British Medical Research Council*

fungi release wide spectrum of volatile organic compounds (vocs) that belong to several chemical groups with different biochemical origins such as monoterpenes, sesquiterpenes, alcohols, aldehydes, aromatic compounds, esters, furans, ketones, sulfur and nitrogen compounds. trichoderma species are the most studied fungal biocontrol agents and are successfully used as biofungicides and biofertili...

In many applications, the radionuclidic purity of a radioactive substance is crucial property. It involves, for example, production radiopharmaceuticals or reference standards used in metrology. However, identification admixtures not straightforward certain nuclides. The paper presents technique determination radionuclide impurities mixtures pure beta-emitting proposed method based on compariso...
