Background Our recent findings have shown that the rat testis is subjected to significant oxidative stress during the early phase of diabetes induced by Streptozotocin (STZ). In the present study, we have investigated whether oral supplementation of β-carotene (BC) to pubertal rats would provide protection against diabetes associated oxidative stress in testis and liver.

An experimental investigation was conducted to find the effect of spraying method of coating of Thermal Barrier Coatings (TBCs) on their oxidation behaviour and resistance to various thermal loading. Isothermal and thermal shock tests were performed in order to study oxidation behaviour of air plasma sprayed Bond Coat (BC) and assess its effect on TBCs lifetime under the stated loadings. Specim...
principle that most of us are linked by short chains of acquaintances — was first investigated as a question in sociology and is a feature of a range of networks arising in nature and technology. Experimental study of the phenomenon revealed that it has two fundamental components: first, such short chains are ubiquitous, and second, individuals operating with purely local information are very a...
شبکه های توزیع به علت سطح ولتاژ پایین و در نتیجه جریان بالا دارای تلفات توان بسیار زیاد و افت ولتاژ بالا می باشند. یکی از روش های مناسب و کم هزینه به منظور کاهش تلفات و بهبود مشخصه ولتاژ در شبکه های توزیع تغییر پیکربندی شبکه یا بازآرایی شبکه های توزیع می باشد. شبکه های توزیع برای دارا بودن قابلیت اطمینان بهتر معمولاً به صورت حلقوی یا غربالی طراحی می شوند. اما مشکلات حفاظتی مانند سطح اتصال کوتاه ...
