در آخرین گزارش (jnc)joint of national committee فشار خون سیستولیک بین 139-130 میلی متر جیوه و فشارخون دیاستولیک بین 89-85 متر جیوه بعنوان فشارخون high-normal معرفی شده است. در مطالعات مختلف نشان داده شده است که این مرز از فشار خون در طولانی مدت بر سلامت افراد تاثیر دارد و یکی از مهمترین پیش زمینه های ابتلا به هیپرتانسیون می باشد. مطالعه حاضر با هدف تعیین شیوع و مشخص کردن سایر پارامترهای...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Objective: The aim of this study was to investigate the effect of a short period of cryotherapy on strength and ankle position sense in professional wrestlers. Methods: In this semi experimental study, fourteen Professional wrestlers (age 24/2+3/5 years old, and weight 74/1+19/2 kg), all of whom had at least five years training experience with provincial and national championships participated...
Abstract Background: The measurement of hand grip strength has several clinical applications to evaluate chronic hand disability, response to treatment, and work capacity after hand injury. Methods: We measured hand grip strength of 41 adults and compared their maximum strength with radiographic indices. Results: There was a significant relationship between hand grip strength and carpal height...

In this paper experimentally, the friction-stir welding of the polypropylene sheets with 40% glass fiber has been investigated. Comparison to other welding methods, the strength of the joint is the most important feature in this process. Many parameters such as tool geometry, rotational speed, linear velocity, and tilt angle are very important as input parameters in this type of welding. Theref...
in this study, friction stir spot welding (fssw) is applied to join the tial6v4 titanium alloy with 1.5 mm thickness and then the effect of rotational speed and tool dwell time on microstructure and mechanical properties is investigated. in this regard, the speed of the tool rotation was considered as 800, 1000, and 1200 rpm, as well as the tool dwell time was set at 7 and 12s. microstructural ...
