a modified model has been analytically developed to describe the induction time of an elliptic air bubble in contact with an elliptic hydrophobic oil droplet. the role of hydrophobicity was revealed in the slippage of liquid over the surfaces of bubble and droplet. in this condition, the analytical relationships for pressure distribution and consequently hydrodynamic resistance force through th...
the antioxidant activities of tbhq, bht and tocopherol mixtures at different concentrations (0, 100, 200, 400 mg/kg) have been evaluated by the application of differential scanning calorimetry (dsc) and rancimat apparatus. rancimat apparatus that measures the secondary oxidation products was set at 110 ⁰c with an air flow of 18-20 l/h to measure the induction period (ip) of the samples. the dsc...
as one of the most promising distributed generation (dg) sources, wind power technology has been widely developed in recent years. doubly fed induction generator (dfig) is currently employed as one of the most common topologies for wind turbine generators (wtgs). this generator operates as a synchronous/asynchronous hybrid generators. therefore, it is necessary to power engineers find understan...
This paper is concerned with alleviating the choice of learning biases via a two-step process: ? The set of all hypotheses that are consistent with the data and cover at least one training example, is given an implicit characterization of polynomial complexity. The only bias governing this induction phase is that of the language of hypotheses. ? Classiication of further examples is done via int...
چکیده روشهای جلوگیری ازتشکیل هیدرات یکی از مسایل مهم صنعت گازطبیعی می باشد. تحقیق حاضر با درک اهمیت بازدارنده های تشکیل هیدرات برای جلوگیری از مسدود شدن مسیر انتقال گاز طبیعی، دو ترکیب nacl و na2so4 را به عنوان بازدارنده تشکیل هیدرات متان، مورد مطالعه قرار می دهد تا به این سوال پاسخ دهد که تاثیر بازدارندگی ترمودینا میکی و سینتیکی ترکیبات الکترولیت کلریدسدیم nacl وسولفات سدیم na2so4 بر تشکیل هی...
Tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. On the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant E. coli, and consequently fed-batch culture have received less attention....

Background: Any time before labor that termination of pregnancy for mother and fe-tus is better than keeping pregnancy, this is indication of induction for labor. The condi-tion of cervix is the most important factor for labor induction. Cervical condition, In many cases that candidate for induction of labor before labor pain, is poor. As the cervical ripening is quite important for success of ...
The induction characteristic of halothane in nitrous oxide and oxygen were compared with halothane in oxygen alone and intravenous induction with thiopentum and succinylcholine.Materials and Methods: A vital capacity technique was used for the gaseous induction groups using a mapleson F system and a 1-litre reservoir bag. four end points of anesthesia were recorded: time to cessation of hand gr...
