growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
Four species of the Hawaiian Drosophila ph i t ib ia subgroup which are homosequential in their polytene chromosomes are resident on the islands of Molokai, Maui and Hawaii. Comparisons of DNA sequence divergence in these four have been made by hybridization of total single-copy radiolabeled tracer DNA from each of the species with excess nonlabeled DNA from each of the species, and measurement...
Introduction: Correct interpretation of kidney images requires the knowledge of its normal size. This study aimed to establish normal values for kidney length and parenchymal thickness and identify the potential related factors in a group of Iranian adults. Methods: Renal dimensions, including length and parenchymal thickness were measured by sonography in 103 individuals with n...
The continuous culture of mosquitoes is a costly endeavor for vector biology laboratories. In addition to the resources that must be committed to colony maintenance, biological costs, including genetic drift and accidental colony loss, also can occur. Although alternatives do exist, their application to mosquitoes is limited. Mosquito cryopreservation remains elusive, and many important species...
Assessing freezing community response and whether freezing resistance is related to other functional traits is essential for understanding alpine community assemblages, particularly in Mediterranean environments where plants are exposed to freezing temperatures and summer droughts. Thus, we characterized the leaf freezing resistance of 42 plant species in 38 plots at Sierra de Guadarrama (Spain...
the purpose of this quantitative study was to investigate the relation between efl teachers’ self-efficacy beliefs and their success. moreover, the study was an analysis of the teacher age, gender and years of teaching experience, to examine the manner in which these factors relate to teacher self-efficacy as defined by bandura (1997) and teaching effectiveness as evaluated by their own student...
