In this paper some characteristics of age parameter(s) are studied on the basis of showers from Yakutsk array data [1] having energy ranging from 1018 eV to 1019 eV.
Genome Characterisation of Enteroviruses 117 and 118: A New Group within Human Enterovirus Species C
The more than 120 genotypes of human enteroviruses (HEVs) reflect a wide range of evolutionary divergence, and there are 23 currently classified as human enterovirus C species (HEV-C). Two new HEV-C (EV-C117 and EV-C118) were identified in the Community-Acquired Pneumonia Pediatric Research Initiative (CAP-PRI) study, and the present paper describes the characterisation of the complete genome o...
Previous findings of low levels of reverse transcriptase (RT) activity in chick cell-derived measles and mumps vaccines showed this activity to be associated with virus particles containing RNA of both subgroup E endogenous avian leukosis viruses (ALV-E) and endogenous avian viruses (EAV). These particles originate from chicken embryonic fibroblast (CEF) substrates used for propagating vaccine ...
ارزش کارکنان یکی از مفاهیم اصلی در مدیریت منابع انسانی است و اندازهگیری میزان آن نیز از اهمیت بالایی برخوردار است. تاکنون روشهای اندازهگیری ارزش کارکنان بهصورت کیفی بیان شدهاند؛ بهطوریکه برای ارزش کارکنان مؤلفههایی در نظر گرفته میشود و براساس تحلیل متغیرها، میزان ارزش کارکنان به دست میآید. البته در تحقیقات این حوزه حتی مؤلفههای یکپارچه و پرسشنامه منسجمی برای سنجش این مفهوم وجود...
BACKGROUND An outbreak of enterovirus D68 (EV-D68) caused severe respiratory illness in 2014. The disease spectrum of EV-D68 infections in children with underlying medical conditions other than asthma, the role of EV-D68 loads on clinical illness, and the variation of EV-D68 strains within the same institution over time have not been described. We sought to define the association between EV-D68...
Recently two new degree concepts have been defined in graph theory: ev-degree and ve-degree. Also the evdegree and ve-degree Zagreb and Randić indices have been defined very recently as parallel of the classical definitions of Zagreb and Randić indices. It was shown that ev-degree and ve-degree topological indices can be used as possible tools in QSPR researches . In this paper we d...
Introduction: Sexhormones are one of most important factors in difference of learning and memory between tow sexes (male & female). High concentration of estrogen and androgen receptors and mechanism of testosterone and estrogen production in learning and memory center, especially in hippocampus show the role of this receptors, sexhormons and P450 enzymes in spatial memory. Consequently, in thi...
