Background: Fear is an important emotion that can be adaptive to promote security and survival or to be negatively maladaptive with effect on the quality of life. The aim of the present study was extracting psychometrics features and factor structure of the Fear Survey Schedule for Children—revised in sample of Iranian children and adolescents. Methods: The present study included the ...
Background: Overweight and obesity, as physical disorders, can threaten health in different ways. Regular exercise (training) is defined as an improving factor for body composition and cardiorespiratory fitness in overweight and obese people. However, the intensity of exercise, as one of the training principles, for attaining the highest fat burning effect, is still challenged. This paper revie...
بررسی پارامترهای مکانیک شکست (ضریب شدت تنش و انتگرال j) در مخازن کامپوزیتی با آستری فلزی (مخازن cng)
چکیده ندارد.
pattern of feeding and reproduction of amblypharyngodon mola (hamilton, 1822) was studied in two floodplain lakes of north 24 parganas districts of west bengal in india during 2011. results indicated that the fish exhibited a predominantly herbivorous diet with algae as the main content of gut. a long, thin walled, coiled gut and closely packed filamentous gill racker suited this feeding habit...
The initial stage of fretting fatigue crack growth is significantly influenced by tangential force induced by fretting action along the contact surface where a mixed-mode crack growth is involved. Fretting crack behavior of aluminum alloy 2024 was studied, taking into account the problem of contact asperities. Finite element was used for the determination of the stress field near the contact su...
Present study deals with the prediction of crack initiation angle for mixed mode (I/II) fracture using finite element techniques and J-Integral based approach. The FE code ANSYS is used to estimate the stress intensity factor numerically. The estimated values of SIF were incorporated into six different crack initiation angle criteria to predict the crack initiation angle. Single edge crack spec...
In this research, energy data of the country from 1374 to 1397 are presented and econometric analysis and decomposition analysis methods (Laspeyres and Logarithmic mean Divisia index) are used to identify and determine the effect of activity, structure and energy intensity on energy consumption. The results of econometric method analysis show that the fitted function of energy consumption based...
Introduction: Cardiovascular problems and atrial fibrillation is one of the most prevalent secondary consequences in hemodialysis patients. This study aimed to examine the effect of high intensity interval training on the level of atrial fibrillation, fibroblast growth factor 23 and Klotho in male rats with chronic kidney disease. Methods: In this study, 30 male rats Wistar (7-8 weeks) were ra...
In this study, displacement field around v-notches of a poly methyl metha crylate (PMMA) specimen with tip cracks will be analyzed using digital image correlation technique. First intensity factor in combination with in-plane rigid body translations and rotation components will be determined by linear least squares fitting of the displacement field data to the corresponding relations among stre...
Now a days product development using prototype methods for actual usage is a growing concept in engineering. Present work deals with simulation of Compact Tension specimen to get fracture parameters J – integral and Stress intensity factors of product built by polyjet technology 3D printer additive manufacturing system. FEA simulation is carried out with the help of Abaqus software by simulatin...
