Introduction: Brucellar epididymo-orchitis (BEO) is the most common variant of genitourinary brucellosis and is encountered in 2 to 20% of patients with brucellosis. This report details clinical and laboratory features, diagnostic evaluations, treatment modalities, and final outcomes for 14 patients with brucellar epididymo-orchitis. Material and Methods: In this retrospective study, we describ...

A finite element thermal analysis is performed for the various configurations of the ATLAS barrel SCT module. The design of the module are based on the recent proposal by RAL to reduce the overall radiation thickness of the module. Its several variations are also evaluated. The main goal of the present calculation is to estimate the safety margin for the thermal runaway. Eight different module ...

The electrical properties, the spontaneous polarization, and the piezoelectric response of ZnO can be tailored by alloying ZnO with BeO for applications such as electrodes in flat panel displays and solar cells, blue and ultraviolet (UV) light emitting devices, and highly sensitive UV detectors. We present here the results of a study that employs density-functional theory to analyze the crystal...

The present paper proposes an extension of the traditional evaluation of the MTF curves in the case in which the acquisition system is not available and the input is not well known, if a relatively low quality of the result is accepted. The method is at first applied when only the acquisition system is unknown, and then when also the input is not well known; in this case the face and the right ...
