Based on the univariate dimension-reduction method (UDRM), Edgeworth series, and sensitivity analysis, a new for reliability analysis of mechanical components is proposed. The applied to calculate response origin moments their with respect distribution parameters (e.g., mean standard deviation) fundamental input random variables. series used estimate failure probability by using first few centr...
PURPOSE The aim of this study was to map the sensitivity of the marginal and other conjunctival regions and to investigate changes in the sensitivity of these regions when determined in the morning and evening. METHODS Thirty-five healthy, noncontact lens wearers (20 female, 15 male; age 27.7 ± 7.3 years) were enrolled. Mechanical sensitivity was measured at 8 locations on the ocular surface ...
Thermobaric charge PBXIH-135 is an explosive with desirable mechanical and safety characteristics. In present research, this PBX charge is provided on scale of 2 kg and its physical, mechanical, sensitivity and performance parameters were investigated. Prepared sample has density of 1.64 g/cm3, hardness of 53 Shore A, tensional strength of 1.68 MPa and strain of 44%. Impact and friction sensiti...
PURPOSE To determine corneal sensitivity to selective mechanical, chemical, and thermal (heat and cold) stimulation in patients with a history of herpes simplex virus (HSV) keratitis. METHODS Corneal sensitivity to different modalities of stimulus was determined in both eyes of 16 patients with unilateral HSV keratitis diagnosed 1 to 12 months before the study. On slit lamp examination, 13 HS...
انسداد حاد سیستم ادراری یکی از علل شایع مراجعه بیماران به کلینیک ارولوژی می باشد. انسداد سیستم ادراری توسط اروگرافی ترشحی و سی تی اسکن (که دارای عوارض ناشی از اشعه یونیزا و عوارض مواد حاجب می باشند)، mri و مواد رادیونوکلئید (که دارای هزینه بالا و صرف وقت زیاد می باشند.) و نیز روشهای تهاجمی نظیر پیلوگرافی آنته گرید و رتروگرید بررسی می گردد. سونوگرافی روشی غیر تهاجمی در بررسی انسادا سیستم ادراری ...
Modulation of touch sensitivity in Caenorhabditis elegans Xiaoyin Chen Sensory perception adapts to diverse environment. Although studies in the last few decades have started to address the question of how sensory systems transduce signals, how these systems cross-modulated is largely unknown. In this thesis, I study mechanosensation in the C. elegans touch receptor neurons (TRNs) to understand...
The partial replacement of RDX with AP attention of many researchers. In this paper, Firstly reasons of replacing part of AP with RDX expressed and the influence of replacing part of AP with RDX on the mechanical, safety and ballistic properties of composite solid propellant have been studied. Using of nitramines in the propellant formulations cause to change in the mechanical properties such ...
