Wind-farm blockage is investigated by means of an analytical model based on the linearized Reynolds-averaged Navier–Stokes equation. Despite simplifications, useful insight obtained about induction region upstream a single wind turbine and cluster turbines. Since linearized, superposition methods are allowed farm as linear all zones each present in farm, including mirrored ones due to presence ...

This study examined the relation of infant emotional responses of anger and sadness to cortisol response in 2 goal blockage situations. One goal blockage with 4-month-old infants (N = 56) involved a contingency learning procedure where infants' learned response was no longer effective in reinstating an event. The other goal blockage with 6-month-old infants (N = 84) involved the still face proc...

Background: Tubal pathology ranks among the most frequent causes of subfertility, next to ovulatory disorders and sperm defects .There fore , assessment of tubal patency is a fundamental part of infertility workup. Investigation for tubal disease can be divided into radiological tests: hysterosalpingography (HSG) , selective salpingography and hystero-contrast-sonography (HyCoSy) , microbiologi...

In this paper, a wave propagation model is developed to investigate the wave propagation in fluid-filled steel pipe. Based on the Kennard shell equations the investigation is achieved under the conditions of coupling between the shell elastic acoustic field and the interior fluid acoustic field. Tests are conducted on fluid-filled pipeline blockage detection. An active acoustic source is used t...

In response to certain environmental stresses, cells display a response characterized by the production of heat shock proteins. In this study we showed that blockage of cells of the yeast Saccharomyces cerevisiae at specific points in the mitotic cell cycle was not in itself a stress that induced the production of heat shock proteins. Nevertheless, cell cycle blockage did not preclude a normal ...
