Parts produced by microforming are becoming ever smaller. Similarly, the foils required in micro-machines are becoming ever thinner. The asymmetric rolling technique is capable of producing foils that are thinner than those produced by the conventional rolling technique. The difference between asymmetric rolling and conventional rolling is the 'cross-shear' zone. However, the influence of the c...
Leukocyte recruitment during inflammation is achieved through a multistep paradigm that includes margination, selectin-mediated rolling, beta 2 integrin-mediated firm adhesion, emigration, and migration into the site of inflammation. We have used the mouse cremaster muscle as a model of trauma- and cytokine-induced inflammation to study the possible role of intercellular adhesion molecule (ICAM...
leaf rolling, especially in cereals, mechanisms for reducing the light receiving surface of the leaves to reduce transpiration rate in response to drought caused. to investigate the effect of drought stress on leaf rolling and leaf anatomical characteristics, yield and yield components in field experiment was conducted bahonar university . in this experiment, five varieties of wheat (shole, omi...
the effect of within-furrow soil compaction and sowing pattern on water use efficiency of sugar beet
this study was conducted in split plot design based on a randomized complete block design in naghadeh region, urmia, iran in 2009-10. two sowing patterns including a1) single row planting with 50 cm between-row spacing, and a2) two rows planting on the hill with 40 cm distance and 50 cm between-row spacing (40×50) were allocated to main plots and four furrow compactions including b1) control, b...
Twin-roll casting AZ31 Mg alloy sheets have been fabricated by normal unidirectional-rolling, head-to-tail rolling, and clock-rolling, respectively. It has been demonstrated that head-to-tail rolling is the most effective to refine the microstructure and weaken the basal texture among the three rolling routes. Excellent integrated tensile properties can be obtained by the head-to-tail rolling. ...
Leukocyte capture and rolling are mediated by selectins expressed on leukocytes (L-selectin) and the vascular endothelium (P- and E-selectin). To investigate the role of core 2 beta1-6-N-glucosaminyltransferase (C2GlcNAcT-I) for synthesis of functional selectin ligands in vivo, leukocyte rolling flux and velocity were studied in venules of untreated and tumor necrosis factor-alpha (TNFalpha)-pr...
Sphingosine-1-phosphate (S1P) participates in inflammation; however, its role in leukocyte rolling is still unclear. Here we use intravital microscopy in inflamed mouse cremaster muscle venules and human endothelial cells to show that S1P contributes to P-selectin-dependent leukocyte rolling through endothelial S1P receptor 3 (S1P3) and Gαq, PLCβ and Ca(2+). Intra-arterial S1P administration in...
سابقه و هدف: با توجه به وفور بالای کژدم mesobuthus eupeus در ایران و نقش چشمگیر این کژدم، به عنوان یکی از عوامل اصلی کژدم گزیدگی در کاشان و اهمیت، مطالعه روی جنبه های مختلف زیستی کژدم، چگونگی کنترل آن ها، این مطالعه به منظور تعیین پراکندگی کژدم مزبور با دو روش صید، rock-rolling و (black light (uv طی سال های 80-1379 در شهرستان کاشان انجام گرفت. مواد و روش ها: این مطالعه به روش توصیفی صورت پذیرفت...
multi frequency vibrations of a system of two isotropic circular plates interconnected by a rolling visco-elastic layer that has nonlinear characteristics are considered. the system with two circular plates and interconnecting discrete continually distributed rolling visco nonlinear elastic rheological elements presents the model of hybrid nonlinear system. the analytical solutions of first asy...
