horizontal transmission of an isolate of the etomopathogenic fungus, beauveria bassiana kcf102, was examined by allowing inoculated eurygaster integriceps put. adults to mate with non-inoculated ones. in case of susceptibility to b. bassiana, there was no significant difference between the males and females. however, there was significant difference among treatments for mortality of non-inocula...

objective(s) sildenafil citrate is a new drug and has special properties that bring about nitric oxide effects on vascular smooth muscle. the aim of this study was to assess the effects of ovarian stimulation and sildenafil citrate injection on pinopode expression in mice. materials and methods thirty adult female mice were randomly divided into three groups: control, hyperstimulated and hypers...

the diagnostic accuracy of single photon emission computed tomography (spect) is profoundly influenced by attenuation phenomenon. soft tissue attenuation degrades cardiac spect image quality, thereby decreasing the possibility of the detection of the lesions. a variety of correction techniques based on different assumptions have been used to reduce the impact of attenuation. several types of sy...

introduction: nowadays, imaging of the myocardial perfusion (mpi) using the single photon emission tomography (spet) in the diagnosis of coronary artery disease, especially myocardial ischemia, is of great importance. in contrast to the coronary artery angiography, mpi is non-invasive, less expensive and more physiological. unfortunately, this image is affected by the some artifacts. these arti...

as we know sol-gel is one of the most important techniques for thin film preparation. in this paper, high transmission silica thin films have been prepared by dip-coating process from a new silicon-alkoxide solution. the prepared sol was stable for 45 days which is very important to characterize the coating process. the optical properties as a function of aging time, withdrawal rate, and heat t...

conclusions applying a simple and brief scale that incorporates the different dimensions of hiv transmission risk may provide policymakers and harm reductionists with a better understanding of hiv transmission in this key group and may be advantageous for evaluating intervention programs. results we extracted 7 items based on first factor, which were accounted for 21% of the variations. the fin...

in this paper, a complete model of an electro hydraulic driven dry clutch along with its performance evaluation has elucidated. through precision modeling, a complete nonlinear physical and full order sketch of clutch has drawn. ultimate nonlinearities existent in the system prohibits it from being controlled by conventional linear control algorithms and to compensate the behavior of the system...

introduction: spirochetes of borrelia can be visualized directly in infected ticks by dark-field microscopy. inoculation of in phosphate buffered saline (pbs) suspension of ground argasid soft ticks to susceptible animals or allowing the ticks to feed on the same species followed by microscopic examination of the animals’ blood have also been practiced. with the advent of molecular methods and ...

the output error of the globoidal cam mechanism can be considered as a relevant indicator ofmechanism performance, because it determines kinematic and dynamical behavior of mechanicaltransmission. based on the differential geometry and the rigid body transformations, themathematical model of surface geometry of the globoidal cam is established. then we present theanalytical expression of the ou...
