Large acceptance magnetic spectrometers, such as PRISMA installed at Laboratori Nazionali di Legnaro, gave a further boost to the renewed interest for multinucleon transfer reactions in the last decade. The large solid angles of these devices and the high resolving powers of their detection systems allowed to investigate the transfer process around and well below the Coulomb barrier and to perf...
background: psychological and behavioral domains are important in coping with type ii diabetes. this study was conducted to assess supportive and coping obstacles in living with type ii diabetes among patients who visited hospitals affiliated to tehran university of medical sciences (tums). methods: this was a cross-sectional study with 600 subjects who participated in the study. data collectio...
Differential charging effects observed in the electron data of the University of California, San Diego, auroral particles experiment on Applied Technology Satellite 6 are described and analyzed. An electrostatic barrier around the environmental measurements experiment (EME) package on ATS 6 is shown to be the natural result of dielectrics around the spacecraft which are more negatively charged ...
Essential to the emergence of spin-based electronics is a source of highly polarized electron spins. Conventional ferromagnets have at best a spin polarization P~50%. Europium monoxide is a novel material capable of generating a highly spin-polarized current when used as a tunnel barrier. EuO is both a Heisenberg ferromagnet (Tc=69 K) and a semiconductor. Exchange splitting of the conduction ba...
Shortwave infrared (SWIR) photon detection has become an essential technology in the modern world. Sensitive SWIR detector arrays with high pixel density, low noise levels, and high signal-to-noise-ratios are highly desirable for a variety of applications including biophotonics, light detection and ranging, optical tomography, and astronomical imaging. As such many efforts in infrared detector ...
Abstract Several efforts to mitigate the spread of COVID-19 and use a minimum three layers masks, it is also necessary apply physical distancing in all work activities both indoors outdoors. This study describes one that researchers can do prevent COVID-19, namely, designing room capacity detection system equipped with temperature detector. The research method an experiment focusing on detector...
Background: This study consists of two parts. The first part deals with both qualitative and quantitative analysis of 226Ra using alpha spectrometry measurement method. In the second part, the percentage of radioactive equilibrium between 226 Ra and its daughter products were determined by alpha spectrometry and total alpha measurement system after elapsed time of 15 days from precipitation. Ma...

One of the most important instruments in gamma ray spectroscopy is HPGe detector. Concept of virtual point detector was considered for Ge(Li) detector. On the basis of this concept, there is a point inside a Ge detector that can be regarded as a fictitious point detector hosting all the interactions. If there is really a point whose response can be considered similar to that of the whole real b...
