With water immersion, gravity is partly eliminated, and the water exerts a pressure on the body surface. Consequently there is a blood volume shift from the periphery to the central circulation, resulting in marked volume loading of the thorax and heart. This paper presents a selection of published literature on water immersion, balneotherapy, aqua exercises, and swimming, in patients with left...
در این پایان نامه به طراحی شبکه های حسگر بی سیم در ساختمانهای هوشمند می پردازیم و در جهت مقایسه دو پروتکل معروف wi-fi و zigbee به اندازه گیری پارامترهای load و packet loss در این پروتکل پرداخته و با پیاده سازی طراحی در شبیه ساز پتولمی به انتخاب بهترین پروتکل با توجه به داده های حاصل از شبیه سازی اشاره می کنیم
BACKGROUND Defects in cardiomyocyte Ca(2+) cycling are a signature feature of heart failure (HF) that occurs in response to sustained hemodynamic overload, and they largely account for contractile dysfunction. Neuronal nitric oxide synthase (NOS1) influences myocyte excitation-contraction coupling through modulation of Ca(2+) cycling, but the potential relevance of this in HF is unknown. METH...
The failure of medium voltage (MV) cables in North Queensland has led Ergon Energy to consider the relative economics of refurbishment or replacement. In order to provide data to inform decision making, an accelerated ageing program has been designed to investigate the ageing of new, field aged, and refurbished cables. This paper describes the considerations affecting the design of the ageing e...
پیشزمینه: در این مطالعه روش تغییریافته تثبیت بهروش «جاگذاری در محفظه استخوانی» (inlay) در بازسازی رباط متقاطع پشتی زانو را معرفی و مشخصات ساختاری تثبیت بهروش «جاگذاری در محفظه استخوانی» با تثبیت به روش جدید و تغییریافته مقایسه گردید. در روش تغییر یافته از پیچ اینترفرانس استفاده شد و عمل جراحی در حالت خوابیده (supine) که قابلیت اجرایی بهتری دارد و از احتمال بروز عوارض عصبی و عروقی حین عمل می...
ObjectivesTo investigate the acute effects of graded hypoxia on external and internal loads during 60 min endurance cycling at a clamped heart rate.DesignRepeated measures.MethodsOn separate visits, 16 trained males cycled for rate corresponding to 80% their first ventilatory threshold sea-level, 2500 m, 3000 3500 m 4000 simulated altitude (inspired oxygen fractions 20.9%, 15.4%, 14.5%, 13.6% 1...
We examine the eect of 10 vol.% TiB whisker reinforcement on transformation superplasticity of Ti±6Al±4V, induced by thermal cycling about the a/b phase transformation range of the matrix under a uniaxial tensile stress. During superplastic deformation, the whiskers gradually align along the external loading axis, as measured by electron back-scattering diffraction of deformed specimens. The c...
Shape memory alloys exhibit a high damping capacity in the mktensite state. Results obtained from both DMA and cyclic tests under tension-compression load show that the martensite damping capacity in NiTi SMAs is a function of both strain amplitude and annealing temperature. Internal friction due to movements of martensite twin boundaries within both elastic (accommodation) and inelastic (reori...
We present a new implementation of MiniAMR, a miniapp for adaptive mesh refinement (AMR) that mimics commonly found workloads and communication patterns in AMR applications. We obtain significant performance improvements by using new data structures and algorithms. One of our important areas of focus in this work is the use of low-overhead distributed load balancing schemes for octree partition...
Interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. To protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. As main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. Ecologically, functional parameters such as stab...
