Background. A stray bullet injury is defined as an accidental firearm injury occurring outdoors by an anonymous attacker. Stray bullet injuries are rare, but not uncommon in certain parts of the world. In Pakistan, 165 patients with stray bullet injuries were recorded between 2006 and 2010. Objectives. In Lebanon, gunshots may occur during politicians’ speeches, funerals and after exam results ...

background: the aim was to study the gastro-intestinal helminths of stray dogs of garmsar, sem­nan province, central iran, and its impacts on human health and animal production. methods : during 2006, the alimentary tracts of 50 stray dogs at necropsy, selected from villages around garmsar, were removed, and examined for helminth infections. subsequently helminths were collected from the conten...

A new class of silicon drift detectors (SDD), called “VortexTM”, with a large active area (~ 0.5 cm), high-energy resolution (<150 eV FWHM) and high-count rate capability (>1 Mcps) has been developed for X-ray diffraction (XRD) and X-ray fluorescence (XRF) applications. The VortexTM design allows for a relatively large active area while still maintaining a very low anode capacitance (~ 60 fF). ...

Accurate detection of quantum states is a vital step in the development computing. Image-charge electrons on liquid helium can potentially be used for readout single-electron qubit; however, low sensitivity due to added noise hinders its usage high-fidelity and high-bandwidth (BW) applications. One method improve accuracy bandwidth use cryogenic amplifications near signal source minimize effect...

Where T is transmittance, I0 is intensity of incident light, I is intensity of transmitted light and Is is intensity of stray light. Stray light has an increasing influence on spectroscopic measurements at low levels of intensity, that is, high absorbances. The result is that stray light causes a negative bias in instrument response and eventually becomes the limiting factor for absorbance and ...

Photodiode-array-based spectrometers are increasingly being used in a wide variety of applications. However, the signal measured by this type of instrument often is not what is anticipated by the user and is often subject to contamination from stray light. This paper describes an efficient and low-cost stray light correction approach based on a relatively simple system using a monochromator-bas...

This paper investigates the influence of power semiconductor parasitic components on ground leakage current in three-phase Current Source Inverter topology, literature called H7 or CSI7. topology allows reducing converter conduction losses with respect to classic CSI, but at same time makes more susceptible capacitances semiconductors devices. In present work, a grid-connected for photovoltaic ...

Aim: This serological survey was undertaken to estimate the prevalence of Toxoplasma gondii in two populations of dogs (stray and owned dogs) in Grenada. Dogs get infected with oocysts voided from cats, definitive hosts of T. gondii. In dogs, T. gondii causes subclinical to clinical disease. Earlier studies conducted in Grenada on a small population of owned dogs showed evidence of exposure to ...

A nonlinear LCR parallel circuit model of a single photon avalanche diode (SPAD) is derived from Lienard-type differential equation. The resistance and the inductance associated with multiplication (AM) are time-dependent governed by time constant due to impact ionization ratio. Time dependences current, voltage, resistance, in analyzed numerically solving During initial generation Geiger-mode ...

Parasitic capacitance has a considerable impact on conductive electromagnetic interference (EMI), especially the common mode (CM) noise. In vehicular applications, such as more electric aircraft and electrical vehicles, value of CM stray can vary during drive cycle, due to some change in environmental, operating conditions, resulting fluctuations EMI level. Designing filters according potential...
