OBJECTIVE This article aims to describe the characteristics of the binaural interaction component (BIC) of speech-evoked auditory brainstem response (ABR). MATERIALS AND METHODS All 15 subjects had normal peripheral hearing sensitivity. ABRs were elicited by speech stimulus /da/. RESULTS The first BIC (BIC-SP1) in the speech-evoked ABR occurred at around 6 ms in the region of peak V. The se...

background: these days, diabetes is deemed as one of the most important health and social-economic problems of the world. since parents play a major role in treatment of diabetes, the most important part of managing diabetes is in the hands of the parents of children affected by diabetes. this special responsibility will increase the stress and family challenges and impacts parents’ emotional r...

in the real world, risk and uncertainty are two natural properties in the implementation of mega projects. most projects fail to achieve the pre-determined objectives due to uncertainty. a linear integer programming optimization model was used in this work to solve a problem in order to choose the most appropriate risk responses for the project risks. a mathematical model, in which work structu...

background: toxoplasma gondii is an obligate intracellular parasite that infects all mammalian cells. several antigens such as excreted/secreted antigens have been identified as a potential vaccine candidate. objective: to determine how excreted/secreted antigens from peritoneal exudates of infected mice (mesa) stimulate cell-mediated immune responses and induce protective immunity against toxo...

this paper aims to assess the application of support vector machine (svm) regression in order to analysis flexible pavements. to this end, 10000 four-layer flexible pavement sections consisted of asphalt concrete layer, granular base layer, granular subbase layer, and subgrade soil were analyzed under the effect of standard axle loading using multi-layered elastic theory and pavement critical r...

background : necessity of evaluating heat stress in the workplace, require validation of indices and selection optimal index. the present study aimed to assess the precision and validity of some heat stress indices and select the optimum index for using in heavy work activities in hot and dry climates. methods: it carried out on 184 workers from 40 brick kilns workshops in the city of qom, cent...

abstract background: in recent years, there has been a rise in the number of premature births. mothers of these newborns experience a high degree of stress over time. since a more comprehensive understanding of this phenomenon can help the healthcare teams in detecting the deficiencies and needs of such newborns’ mothers for a better and more effective intervention, the present study was carrie...

zno nps (zinc oxide nanoparticles) has generated significant scientific interest as a novel antibacterial and anticancer agent. since oxidative stress is a critical determinant of zno nps-induced damage, it is necessary to characterize their underlying mode of action. different structural and physicochemical properties of zno nps such as particle surface, size, shape, crystal structure, chemica...

this paper reports on the findings of a study designed to investigate the cultural and social complexities governing the compliment responses among the persian native speakers. 200 persian respondents took a 24-item discourse completion task (dct) while 15 native field workers were also set responsible for collecting the examples of complimenting exchanges they either observed or participated i...
