یکی از جذاب ترین روش های ماشینکاری مدرن، تخلیه الکتریکی است که در اواخر دهه 1960 معرفی شد. با سیم کاربردهای مختلفی دارد، جمله دقت بالا تمام مواد رسانا مانند فلزات، آلیاژهای فلزی، گرافیت و سرامیک همچنین صنایع هوافضا، خودروسازی سایر صنایع. به منظور افزایش سرعت کاهش زبری سطح عرض شکاف، پارامترهای برش بهینه نقش مهمی انتخاب خروجی دارند. این مطالعه، ورودی (دبی، مدت پالس، فرکانس سیم، کشش جریان دی الکتر...

results mean operative time was shortest in group a (57.1 minutes) and longest in group b [63.4 (p = 0.131)]. mean hospital stay was shortest in group a (2.1 days) and longest in group c (5.7 days) (p = 0.003). hospital expenses were minimal in group a (p = 0.001). male sex, serum bilirubin level, white blood cell (wbc) count, duration of ercp/es procedure, contracted gall bladder and large cal...

Background: The glycoconjugate content of sperms indicates their physiological and fertility properties. Lectin reactivity is indicative of intact, capacitated, and acrosome-reacted sperms. In the epididymis, sperms experience maturation, glycoconjugate modification, and simultaneously, higher L-carnitine (LC) concentrations. The aim of this project was to evaluate the effects of LC and Pentoxi...

Introduction: Barrel cortex of rodents is responsible for sensory information processing from muzzle whiskers. Locus coeruleus (LC) as the main source of norepinephrine (NE) in the cortex, is effective on the sensory information processing. Methods: Rats were divided to 2 groups. One group underwent sensory deprivation (P4) and the other group served as control and did not undergo sensory d...

Onsager’s phenomenological equations successfully describe irreversible thermodynamic processes. They assume a symmetric coupling matrix between thermodynamic fluxes and forces. It is easily shown that the antisymmetric part of a coupling matrix does not contribute to dissipation. Therefore, entropy production is exclusively governed by the symmetric matrix even in the presence of antisymmetric...

Languages instantiate many different kinds of dependencies, holding between adjacent or nonadjacent elements. In the domain of phonotactics, while sensitivity to adjacent dependencies emerges between 6 and 10 months, it is unknown when sensitivity to nonadjacent dependencies emerges. The present study tests a perceptual equivalent of the Labial-Coronal (LC) bias, a dependency involving two non-...

In this paper, the main defects of LC-based Σ∆ modulators due to process variations are presented. Resonance frequency shift of LC tank circuit, which was discussed is some publications, is shown to be one among many other possible defects that are discussed in this paper. The effect of each defect on modulator output spectrum is shown and discussed. It is suggested that the information extract...
