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 ...
Background: Systemic lupus erythematosus (SLE) is a autoimmune disease that affects adolescents and young women of childbearing age. In spite the improvement in fetal maternal SLE pregnancy outcome last decades, they have increased risk adverse outcomes including flare, abortions, preeclampsia (PE) premature birth (PB). However, among with not been well explored. Objectives: To evaluate pregnan...
Graphene is a new material consisting of single layer of sp 2 – bonded carbon atoms. Since its discovery in 2004 [1] graphene has emerged as the “material of the future” due to its unique nanostructure and electrical, thermal and mechanical properties [2,3]. Graphene is now considered as a promising material for application in various technological fields such as transparent conductive films [4...
Due to its small size, large specific surface area and hydrophobicity, microplastics, the adsorbed contaminants may together cause potential negative effects on ecosystems human beings. In this study, kinetics size adsorption of Cu(II), Cr(III), Pb(II) onto PE, PP PET microplastic particles were explored. Results indicated that PE microplastics have higher capacity for than microplastic. The wa...
Abstract Background and Aims Chronic kidney disease (CKD) is a complex heterogeneous increasingly becoming global public health concern. It characterized by persistent inflammation state which appear to be caused cytokines, grown factors hormones. Peritoneal dialysis (PD) accounts for 9% of all replacement therapy (KRT) over time, some changes are expected occur in the peritoneal membrane mainl...

Using firm-level data from 46 countries, we investigate the relation between corruption – the misuse of public office for private gains – and international corporate values. Our analysis shows that firms from more (less) corrupt countries trade at significantly lower (higher) market multiples. This result is robust to the inclusion of many control variables suggested by valuation theory. On ave...
از گذشته، نسبت هایی همچون نسبت جاری و نسبت آنی برای ارزیابی قدرت نقدینگی و توانایی شرکت در بازپرداخت بدهی ها مورد استفاده تحلیل گران بوده است ولی به لحاظ نقص ها و کاستی هایی که این دو نسبت دارا می باشند، در چند سال اخیر نسبت هایی همچون شاخص نقدینگی، شاخص فراگیر نقدینگی، مانده نقدی خالص، دوره تبدیل نقد، لامباو را ارائه داده اند. در این مقاله علاوه بر معرفی این نسبتهای نوین از طریق محاسبه همبستگی...
