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...

PURPOSE To assess effectiveness and durability of Solifenacin (SS) versus tibial nerve stimulation (PTNS) versus combination therapy (PTNS + SS) in women with overactive bladder syndrome (OAB). MATERIALS AND METHODS 105 women with OAB were divided randomly into three groups of 35 patients each. In group A women received SS, in group B women underwent PTNS, in group C women underwent combinati...

To understand the genetic basis of pathways involved in the control of breathing, a large scale, high-throughput study using chromosomal substitution strains of rats is underway. Eight new consomic rat stains (SS-2(BN), SS-4(BN), SS-6(BN), SS-7(BN), SS-8(BN), SS-11(BN), SS-12(BN), SS-14(BN), SS-Y(BN)), containing one homozygous BN/NHsdMcwi (BN) chromosome on a background of SS/JrHsdMcwi (SS), w...

We previously showed that the authentic 5' splice site (5'ss) of the first exon in the human beta-globin gene is intrinsically stronger than a cryptic 5'ss located 16 nucleotides upstream. Here we examined by mutational analysis the contribution of individual 5'ss nucleotides to discrimination between these two 5'ss. Based on the in vitro splicing efficiencies of a panel of 26 wild-type and mut...

BACKGROUND School participation in collecting and reporting syndromic surveillance (SS) data to public health officials and school nurses' attitudes regarding SS have not been assessed. METHODS An online survey was sent to Missouri Association of School Nurses members during the 2013/2014 school year to assess whether K-12 schools were collecting and reporting SS data. Z-scores were used to a...

In real environments, the recorded speech signal is much affected by unwanted noise. Therefore, it is necessary to reduce the unwanted noise from the recorded noisy signal. The spectral subtraction (SS) and the flooring processing-improved SS (F-SS) have been proposed to achieve that. The F-SS iteratively estimates the clean speech signal by utilizing the SS. However, the F-SS generates the dis...

Silk sericin (SS) can accelerate cell proliferation and attachment; however, SS can be extracted by various methods, which result in SS exhibiting different physical and biological properties. We found that SS produced from various extraction methods has different molecular weights, zeta potential, particle size and amino acid content. The MTT assay indicated that SS from all extraction methods...
