In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced wit...

In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the ...

Three strains of facultatively anaerobic thermotolerant and moderately halophilic bacteria were isolated from two Jordanian hot spring locations. The novel Bacillus strains were short rods, Gram-positive, motile and spore formers. The strains were capable of anaerobic (but not aerobic) growth at 63C, moderately halophilic, able to grow at NaCl concentration range of 12 15 % and at temperatures ...

Face recognition is important in human identification. The biological recognition technique acts as a good method and broad applications in security areas. This work presents a method to improve the face recognition accuracy using a combination of Principal Component Analysis (PCA), and Wavelet Transform. Wavelet Transform is used to decompose the input image with different levels and rearrange...

بخش اورژانس یکی از شلوغ‌ترین بخش‌های یک بیمارستان است و بهبود عملکرد این تأثیر بسیاری در کیفیت ارائه خدمات دارد. اخیراً پژوهشگران به­‌دلیل تمرکز مهندسی تاب‌آوری مدیریت ناب بر کارایی سیستم‌ها توجه بسیار زیادی به دو دیدگاه کنار یکدیگر داشته‌اند. هدف پژوهش، رویکردی یکپارچه برای ارزیابی مبتنی شاخص‌های با ارتقای رضایت شغلی کاهش هزینه‌های درمانی واحد خصوصی است. منظور، ابتدا شناسایی مؤثر، مدل مفهومی مس...

صخلملا Infertility affects 15% of couples seeking children worldwide and male factor is evident in about 30-50% of the cases. To assess the effect of sperm chromatin integrity on the outcomes of intracytoplasmic injection, sperm DNA compactness was evaluated by acridine orange staining in 40 fertile and 44 infertile men attending one infertility clinic. The results showed no significant differe...

صخلملا The search for novel anticancer drugs continues. This work includes a preliminary study of the effect of two crude extracts of Greek or Mediterranean sage (Salvia triloba L. f.) on three malignant human cell lines and one malignant murine cell line. A boiling water extract and a methanolic extract were prepared from dried leaves of S. triloba. Yields of extraction were 9.8 and 22.4%, res...
