emittance control in high power linacs
چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
Whitefly control potential of Eretmocerus parasitoids with different reproductive modes
A major component of the evaluation of biological control agents is the study and comparison of their biology, including the reproductive mode. In hymenopteran parasitoids, reproductive modes include thelytoky and arrhenotoky. Since a thelytokous population produces only females, it is assumed that they may be better suited for biological control than an arrhenotokous population. Here we compar...
متن کاملTYLCV-resistant Tomato Cultivar Trial and Whitefly Control Strategies
Tomato yellow leaf curl virus (TYLCV) and tomato spotted wilt virus (TSWV) are common diseases of tomato in Florida. TYLCV occurs in central and southern Florida whereas TSWV occurs in northern Florida and throughout all states of the southeastern USA. TYLCVresistant cultivars and advanced breeder’s varieties are available for commercial use, but vegetable producers don’t often use them. A vari...
متن کاملMitochondrial Biogenesis in Diverse Cauliflower
The early generative phase of cauliflower (Brassica oleracea var. botrytis) curd ripening is 21 sensitive to the water deficit. Mitochondrial responses under drought within Brassica genus are 22 poorly understood. The main goal of this study was to investigate the mitochondrial biogenesis of 23 three cauliflower cultivars varying with drought tolerance. Diverse quantitative changes 24 (down-reg...
متن کاملRNA Interference based Approach to Down Regulate Osmoregulators of Whitefly (Bemisia tabaci): Potential Technology for the Control of Whitefly
Over the past decade RNA interference (RNAi) technology has emerged as a successful tool not only for functional genomics, but in planta expression of short interfering RNAs (siRNAs) that could offer great potential for insect pest management. The diet of insects feeding exclusively on phloem sieves contains water and sugars as main components, and the uptake of the liquid food greatly depends ...
