In design, multiple disparate goals must be addressed simultaneously. It is the thesis of this work that problems in two-dimensional layout design can be solved by collaboration among single-goal, intelligent agents, each responsible for a class of objects and responsive to explicit metrics. In this model, each agent produces conflict-free designs for its own class of objects, and then, when ob...
When tissue is damaged one reaction is the initiation of the haemostatic mechanism. This involves initially platelet interaction with the damaged vessel walls, platelet aggregation and release at the sites of damage, and subsequent local fibrin formation due to the activation of the coagulation cascade after the 'release' of various factors from the activated platelets -namely, Ca++ ions and ph...
سابقه و هدف: شوری خاک و کمبود روی از مهم ترین عوامل محدود کننده رشد و عملکرد درختان پسته در بسیاری از مناطق پسته کاری ایران، از جمله منطقه رفسنجان می باشند. استفاده از باکتری های محرک رشد گیاه یکی از راهکارهای نوین برای افزایش فراهمی عناصرغذایی در خاک و در نتیجه افزایش رشد گیاهان در شرایط شور است. بنابراین، هدف از این پژوهش بررسی برهم کنش باکتری های سودوموناس فلوروسنت و روی بر تغییرات شکل های م...
Introduction: Type B1 CAIs are a major type of refractory inclusion in CV3 carbonaceous chondrites. An intriguing feature of fassaite in many Type B1 inclusions is complex zoning within single crystals. Seen in backscattered electron images (BEIs), the zoning reflects irregular, sometimes patchy, distributions of TiO2 and correlated and anticorrelated oxides; this zoning is not synonymous with ...
background and objectives: soil salinity and zn deficiency are among the most important limiting factors for growth and yields of pistachio trees in many regions of iran, especially in the rafsanjan area. the use of plant growth promoting rhizobacteria (pgpr) is new strategies to reduce destructive effects of salinity and improvement of nutrient availability. this study investigated the interac...
Protofibrils are transient structures observed during in vitro formation of mature amyloid fibrils and have been implicated as the toxic species responsible for cell dysfunction and neuronal loss in Alzheimer’s disease (AD) and other protein aggregation diseases. To better understand the roles of protofibrils in amyloid assembly and Alzheimer’s disease, we characterized secondary structural fea...
This document provides supplementary information for the publication ”Technical Note: Approximate Bayesian parameterization of a process-based tropical forest model” to appear in Biogeosciences. 1 FORMIND model details FORMIND is an individual-based, spatially semi-explicit, dynamic forest model. Spatially semi-explicit means that trees are assigned to a spatial 20x20m grid, but within grid cel...
