background: despite some successful dynamic simulation of self-impact double pendulum (sidp)-as humanoid robots legs or arms- studies, there is limited information available about the control of one leg locomotion. objective : the main goal of this research is to improve the reliability of the mammalians leg locomotion and building more elaborated models close to the natural movements, by mod...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Background During a normal menstrual cycle, progesterone prepares the endometrium for pregnancy by stimulating proliferation in response to human chorionic Gnadotropin produced by the corpus luteum. Many questions were raised about the role of follicular fluid aspiration on the granuloma cells at the time of oocyte retrieving during the ART cycles. Authors believes that oocyte retrieval might d...
conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...
Objective: The purpose of this study was to determine the effect of cycling fatigue on co-activation of knee muscles during running in novice triathletes. Methods: Twelve novice male triathletes aged 23.7±2.1 years participated in this quasi experimental study. Surface electromyographic activity from gastrocnemius, rectus femoris, vastus medialis, vastus lateralis, biceps femoris and se...
Background & Aim: Postpartum depression (PPD) has negative effects on developmental and behavioral functions of newborn, mother-child relationship and mother's health. The etiology of postpartum depression is very complex. Social support is known as a risk factor for postpartum depression. Accordingly the aim of this study was to determine the relationship between social support and its compo...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
monometallic and bimetallic ni and co catalytic nanoparticles supported on titanium dioxide (rutile phase) substrate were prepared by wet impregnation method. these nanoparicles were used as catalysts for synthesis of multiwalled carbon nanotubes (mwcnts) from acetylene decomposition at 700°c by the catalytic chemical vapor deposition (ccvd) technique. the nanomaterials (catalyst and cnts) were...
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...
Objective: Obesity is associated with numerous health problems such as dyslipidemia, hypertension, type II diabetes, cerebrovascular diseases, and coronary heart diseases. Gait as an effective factor in controlling obesity is very important in human motor development. Thus, the purpose of this study was to examine the effects of obesity and slimming on the gait kinematics in children. Methods:...
