In this study, electroless Ni-B depositions were achieved on the St-37 steel substrates at different NaBH4 concentrations and 950 oC 1 hour. Electroless deposited samples had a cauliflower-like surface texture that makes lubricating naturally as concentration increased, grain size decreases in microstructure. XRD spectra of sample showed partial amorph region together with crystalline region. M...

Description The package handles pre-processing, normalization, filtering and analysis of Affymetrix GeneChip expression arrays, including exon arrays (Exon 1.0 ST: core, extended, full probesets), gene arrays (Gene 1.0 ST) and plate arrays on computers with 1 GB RAM only. It is an R wrapper to XPS (eXpression Profiling System), which is based on ROOT, an object-oriented framework developed at C...

a survey was carried out in the summer of 1972 in east azerbaijan, northwest iran, to determine the prevalence of cardiovascular disease. ecg tracings were prepared from 198 women and 178 men aged 40-60. only 45% of the tracings were completely normal. q/qs abnormalities were found in 4.7% of tracings, left axis deviation in 4% tall r wave in 37%, st depression in 3.9% of men and 14.1% of women...

Background Staphylococcus aureus ( S. ) is the most common causative agent of burn wound infection, that often leads to high morbidity and mortality. However, there not enough knowledge about molecular epidemiology antimicrobial susceptibility isolates from infections in Fujian, China. Methods Between 2016 2021, 90 were collected China, including 59 methicillin-resistant (MRSA) strains 31 methi...

OBJECTIVE To evaluate the results we obtained from 37 patients referred to our clinics with resorbable plate-screw systems which have been claimed as biodegradable fixation materials and used in craniofacial, maxillofacial and orthopedic reconstructive procedures owing to their advantages such as biocompatibility, adequate biomechanical resistance, longer dwelling time, elimination through phys...

Pemilihan arus pengelasan yang mempengaruhi hasil adalah parameter pengelasan, kualitas di pengaruhi oleh energi panas yaitu las. apabila pemilihan las kurang tepat maka tidak akan teratur, melebar dan rata. Penelitian ini bersifat eksperimen suatu cara untuk mencari hubungan sebab akibat antara dua faktor saling berpengaruh. Dengan melakukan pemeriksaan pengujian dengan terhadap sifat-sifat me...

In the present investigation, a novel focusing technique is proposed and demonstrated to enhance strength of synthetic jet array (SJ array). Here, for same geometric operating parameters, SJ achieved by providing non-linear phase delay (∅) between actuators. An open-source software, OpenFOAM, used study influence Strouhal number (St=0.028, 0.086, 0.13) ∅ s (range: 0°−180°) on behavior fixed Rey...
