the pathophysiology of primary benign exertional headache (eh) is not still clearly defined. some researchers have suggested an impaired vascular response as the etiology of this disorder. in this study we investigated whether there are any differences in blood pressure (bp) and heart rate (hr) of the subjects in course of the static and dynamic exercises and the treadmill stress test between t...
the purpose of this study is to investigate the effect of physical activity onmemory and dynamic balance of elder people. subjects (n=15) were selected asvolunteers. the intervention was performed in an eighteen session period, threetimes a week (each session, 45 minutes). yoga training was performed for mentalrelaxation. wexler test was performed for memory evaluation. seat up test wasused to ...
the molecular dynamic technique was used to simulate the nano-indentation test on the thin films of silver, titanium, aluminum and copper which were coated on the silicone substrate. the mechanical properties of the selected thin films were studied in terms of the temperature. the temperature was changed from 193 k to 793 k with an increment of 100 k. to investigate the effect of temperature on...
Objective: Balancing is the most basic function of the neuromuscular system in performing all simple and complex activities that contribute to health-related physical fitness. Core stability may be a contributing factor to static and dynamic balance. The aim of this study was to investigate the relationship between core stability muscle endurance and static and dynamic balance in basketball pla...
High dynamic range (HDR) imaging seems to have developed to a level of soon being a standard feature in consumer cameras. This study was motivated by the need for evaluating tone mapping operators especially for consumer imaging applications. A no-reference method based on ISO 20462-2:2005 triplet comparison was created for evaluating tone mapping operators. Multiple HDR test images were photog...
Objective: Somatotype is a method to describe the human physique which can influence postural control. The aim of this study was the relationship between somatotype and static, semi-dynamic and dynamic postural control. Methods: 140 females 12-50-year-old(26.45±10.94) participated in this study who had no skeletal, vestibular and neurological abnormalities and no trauma or pain in lower extrem...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
Abstract Introduction: Coordination and balance is an indicator to determine the degree of independence of the elderly in performing daily activities. Method: In this quasi-experimental study, with a pre-test-post-test design, 30 elderly men referred to Arak nursing home with a mean age (68.03 ± 6.05 years), weight (62.20 ± 9.50 kg) height (163.77 ± 6.93 cm) was available as a sample and random...
Dynamic modulus characterizes the viscoelastic behavior of asphalt materials and is the most important input parameter for design and rehabilitation of flexible pavements using Mechanistic–Empirical Pavement Design Guide (MEPDG). Laboratory determination of dynamic modulus is very expensive and time consuming. To overcome this challenge, several predictive models were developed to determine dyn...
This study is conducted under the domain of Vygotskian Socio-cultural Theory (SCT) of mind and the notion of dynamic assessment to elevate the linguistic accuracy of EFL learners’ writing skill. 40 homogenous intermediate EFL learners from four intact classes were divided into two dynamic assessment (DA) and non-dynamic assessment (NDA) groups. As a pre-test, the participants were given writing...
