introduction: the proportion of older adults in the population continues to grow in the developing countries. in addition, persons at or over the age of 60 years have decreased quality of life in geriartrics because of several factors, such as low physical activity and impairment in mobility. this study was performed to assess the effect of group-based exercise program on physical functional in...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
هدف: تحقیقات بر روی tilt board که اختصاصاً جهت تمرینات تعادلی طراحی گشته بسیار محدود است. هدف ما در این مطالعه بررسی اثر تمرین با tilt board بر مولفه های استاتیک و دینامیک تعادل بعد سکته بود. روش: در این مطالعه ?? بیمار همی پلژی شرکت داشتند که بطور تصادفی به دو گروه مداخله و کنترل دسته بندی شدند. بیماران با استفاده از آزمون های کلینیکی، دستگاه force plate و biodex قبل و بعد درمان مورد ارزیابی ...
according to webster and wind (1972) and anderson et al (1987), “organizational buying is a complex process and involves many people from different functional areas, multiple goals and potentially conflicting decision criteria. moreover, the customers of today are also more knowledgeable and selective when making their purchasing decisions. since a key to organizational survival is the retentio...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
In this study, the response is derived, high-energy material 1-(4-nitrophenyl)-1H-Tetrazole (NPHT) with boron nitridenano-cages in different conditions of temperature, density functional theory methods were studied. for this purpose, the material on both sides were geometrically optimized, then the calculation of the thermodynamic parameters were performed on all of them. The amount of ΔH, ΔS a...
In this article, synthesis of the explosive synthesis of tetrazolo [1,5-b][1,2,4]triazine from the reaction of 1,5-diaminotetrazole with glyoxal in different conditions of temperature, with density functional theory method were studied. For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then the calculation of the thermodynamic paramet...
The present study aimed to investigate the role of adenylyl cyclase activator in preventing diabetic nephropathy via antioxidant activity in rats. Biochemical parameters were performed to confirm Streptozotocin induced nephropathy in rats. Male Wistar rats were used in the present study to reduce the effect of estrogen. Rats were subjected to high fat diet (HFD) for two weeks followed by low do...
TITLE : Using constraints on neuronal activity to reveal compensatory changes in neuronal parameters
In this study, we developed a general description of parameter combinations for which specified characteristics of neuronal or network activity are constant. Our approach is based on the implicit function theorem and is applicable to activity characteristics which smoothly depend on parameters. Such smoothness is often intrinsic to neuronal systems when they are in stable functional states. The...
Olypher AV, Calabrese RL. Using constraints on neuronal activity to reveal compensatory changes in neuronal parameters. J Neurophysiol 98: 3749 –3758, 2007. First published September 12, 2007; doi:10.1152/jn.00842.2007. In this study, we developed a general description of parameter combinations for which specified characteristics of neuronal or network activity are constant. Our approach is bas...
