We report on the realization of functional infrared light concentrators based on a thick layer of air-polymer metamaterial with controlled pore size gradients. The design features an optimum gradient index profile leading to light focusing in the Fresnel zone of the structures for two selected operating wavelength domains near 5.6 and 10.4 μm. The metamaterial which consists in a thick polymer ...
Centriolar satellites (CS) are small granular structures that cluster in the vicinity of centrosomes. CS are highly susceptible to stress stimuli, triggering abrupt displacement of key CS factors. Here we discover a linear p38-MK2-14-3-3 signalling pathway that specifically targets CEP131 to trigger CS remodelling after cell stress. We identify CEP131 as a substrate of the p38 effector kinase M...
Increasing population growth and decreasing land ratio made it difficult for rural people of Bangladesh to maintain their livelihood. Especially the small-scale farmers find it trickier using their scarce resources. One House One Farm approach(OHOF) is designed to utilize the house and farm resources of the small- scale farmers to improve their livelihood. The focus of the study was to determin...
THIS little book by Professor Rendle Short sets out to give an account of the structure and functions of the human body for the non-medical reader, and to present the student of physiology with accurate and up-to-date facts from a somewhat unusual angle. There is no doubt that the author succeeds in both these objects, and he gives a most interesting and instructive set of chapters ranging in s...
تهیه ترکیب فسفرتری کلرید بااستفاده از واکنش فسفر سفید(زرد) و گاز کلر در فاز محلول و درمقیاس آزمایشگاهی موردمطالعه قرارگرفت .پس از انتخاب مناسبتر روش و انتخاب بهترین شرایط کوشش درجهت طراحی واحد نیمه صنعتی انجام شد و توانستیم دراین راستا به تولید 10 کیلوگرم درساعت باخلوص 99/5 درصد برسیم . abstract the preparation of phosphorous trichloride by the reaction of white phosphorous and chlorine gas in ...
a fundamental study of scale formation of calcium carbonate (caco3) for producing oil wells hasbeen carried out. this article presents the study of the prediction of salt deposition in two differentsynthetic formation waters and investigates the effects of temperature and pressure on calciumcarbonate precipitation. the dependence of the induction period of the precipitation of calciumcarbonate ...
The Beef Information Nucleus is a series of large, well structured progeny test programs undertaken by Breed Societies with cofunding assistance from Meat & Livestock Australia (MLA). Young bulls of high genetic merit are joined by either AI or natural mating to a commercial cow base to produce progeny which are managed commercially as one cohort and measured for a range of economically traits....
educational researchers have provided evidence that teachers’ emotional intelligence has strong effects on various aspects of teaching and learning. yet, in the field of teaching english to speakers of other languages (tesol), inquiry into teachers’ emotional intelligence is nearly limited. given its documented powerful impact on teaching practices and student learning, it is critical to pursue...
در این مطالعه ژنومی متشکل از 10 کروموزوم هر یک به طول 200 سانتی¬مورگان شبیه¬سازی شد. نشانگرها بر روی ژنوم با فواصل 2/0 سانتی¬مورگان طراحی شدند و جایگاههای ژنی مؤثر بر صفات بر روی ژنوم با توزیع تصادفی و تعداد متغیر شبیه¬سازی شدند و تنها اثرات افزایشی ژنها در نظر گرفته ¬شد. در ابتدا جمعیت پایه¬ای از حیوانات با اندازه مؤثر 100 (50 نر و 50 ماده) شبیه¬سازی شد و این ساختار جمعیتی برای 50 نسل با آمیز...
