شناخت پارامترهای آب و هوایی و اثر آنها بر روی گیاهان زراعی یکی از مهم ترین عوامل موثر در افزایش عملکرد و به تبع آن بالا بردن تولید می باشد . نوسانات عناصر اقلیمی از همه مهمتر بارش تاثیر زیادی بر روی محصولات دیم می گذارد . این تحقیق با هدف بررسی نوسانات بارش در استان زنجان و شرایط آب و هوایی ایستگاه های منتخب و اثرات آن بر روی عملکرد گندم دیم صورت گرفته است . به این منظور از شاخص بارش استاندارد ...
Abstract Trials were conducted in two experimental runs at the Purdue University Horticulture Greenhouses, West Lafayette, IN, to determine ‘Redefined Murray Mitcham’ peppermint tolerance tiafenacil. Established 20-cm-diameter polyethylene pots was subjected a simulated harvest by removing aboveground biomass substrate surface; then, tiafenacil applied 0, 25, 50, 100, and 200 g ai ha −1 . Visib...
In the paper we present some methods of constructing cryptosystems utilising chaotic dynamical systems that has been extensively developed last years. We start with a brief review of algorithms based on both the theory of continuous and discrete systems. Then we show our approach where the essence of chaos (that is the sensitivity of the trajectories of discrete chaotic dynamical systems to the...
To assess the effect of micro-organisms on the reduction of wax appearance temperature (WAT) of waxy crude oil, some appropriate strains were obtained from contaminated samples exposed to hydrocarbon compounds for a long time. By conducting some screening tests, four strains were chosen and aerated in a bioreactor; they were then grown in some hydrocarbon environments in order to produce biolog...
Hairy Vetch Derived-N Uptake by Tomato Grown in a Pot Containing Fast- and Slow-release N Fertilizer
In order to improve the use efficiency of a cover crop, hairy vetch (Vicia villosa R., HV), and supplemental chemical N fertilizer, N release and uptake patterns from HV, fast-release N fertilizer (Fast), and slow-release N fertilizer (Slow) in fresh market tomato (Solanum lycopersicum L.) production were investigated using the 15N-labeling method. In the incubation of soil-added N at two mix r...
Surgical removal of body fat (lipectomy) triggers compensatory increases in nonexcised white adipose tissue (WAT), thus restoring adiposity levels in many species, including Siberian hamsters. In Siberian hamsters, when their lipectomized WAT is transplanted to another site (autologous grafts, no net change in body fat), healthy grafts result, but the lipectomy-induced compensatory increases in...
The origins of the sympathetic nervous system (SNS) innervation of white adipose tissue (WAT) have been defined using the transneuronal viral retrograde tract tracer, pseudorabies virus. Activation of this SNS innervation is acknowledged as the principal initiator of WAT lipolysis. The central control of WAT lipolysis may require neural feedback to a brain-SNS-WAT circuit via WAT afferents. Ind...
Obesity-induced inflammatory changes in white adipose tissue (WAT), which caused dysregulated expression of inflammation-related adipokines involving tumor necrosis factor-α and monocyte chemoattractant protein-1, contribute to the development of insulin resistance. Moreover, current literature reports state that WAT generates reactive oxygen species (ROS), and the enhanced production of ROS in...
Converging evidence indicates that white adipose tissue (WAT) is innervated by the sympathetic nervous system (SNS) based on immunohistochemical labeling of a SNS marker (tyrosine hydroxylase [TH]), tract tracing of WAT sympathetic postganglionic innervation, pseudorabies virus (PRV) transneuronal labeling of WAT SNS outflow neurons, and functional evidence from denervation studies. Recently, W...
White adipose tissue (WAT) is innervated by the sympathetic nervous system (SNS), and the central origins of this innervation have been demonstrated for inguinal and epididymal WAT (iWAT and eWAT, respectively) using a viral transneuronal tract tracer, the pseudorabies virus (PRV). Although the more established role of this sympathetic innervation of WAT is as a major stimulator of lipid mobili...
