در این پژوهش رفتار سایشی کامپوزیت های wc-feal-b در دماهای بالا بررسی گردیده است. بر این اساس کامپوزیت تجاری(wc-10wt%co (h10f ساخت شرکت سندویک سوئد با کامپوزیت های wc-40vol%co و wc-40vol%feal با مقادیر مختلف بور از صفر تا ppm1000 سنتز شده به روش زینترینگ فاز مایع از نظر خواص مکانیکی و رفتار سایش دما بالا مقایسه شدند. این کامپوزیت ها از نظر فازهای تشکیل دهنده، ریزساختاری، سختی، چقرمگی شکست و رفتا...
BACKGROUND For the elderly, the association between waist circumference (WC) and mortality considering body mass index (BMI) remains unclear, and thereby also the evidence base for using these anthropometric measures in clinical practice. This meta-analysis examined the association between WC categories and (cause-specific) mortality within BMI categories. Furthermore, the association of contin...
The transcription factors WHITE COLLAR-1 (WC-1) and WHITE COLLAR-2 (WC-2) interact to form a heterodimeric complex (WCC) that is essential for most of the light-mediated processes in Neurospora crassa. WCC also plays a distinct non-light-related role as the transcriptional activator in the FREQUENCY (FRQ)/WCC feedback loop that is central to the N. crassa circadian system. Although an activator...
How historical factors have affected the application of workers' compensation data to public health.
A recent meeting of leading workers' compensation (WC) researchers was held in Washington, DC to consider ways of improving the use of WC data for injury and illness prevention. Participants identified specific deficiencies that limit the application of WC data for research purposes. For example, commercial insurers are often reluctant to provide claims records to research organizations. Unlike...
Tungsten carbide has been proposed to be a potential inexpensive alternative to platinum for catalyzing hydrogenation reactions. Using density functional theory (DFT) calculations, we performed a systematic study on the geometries and electronic structures of small (WC)n (n 1⁄4 1–10) clusters. A cubic-like growth of WC clusters was found to be the preferred pathway. The interactions between the...
Background and Aim: Although several studies have been conducted about the effectiveness of general and central obesity anthropometric indices on lipid profile, a few surveys are available concerning their relationship. As the determination of the best anthropometric index for the prediction of lipid profile in any population is necessary, the current study was carried out to find out the best ...
OBJECTIVE Central adiposity is a component of the metabolic syndrome (MetS). Little is known about the impact of medical weight loss and decreased waist circumference (WC) on the MetS. Our objective was to assess the impact of changes in WC on blood pressure, lipids and glycemia. RESEARCH DESIGN AND METHODS We studied 430 obese patients enrolled in a 2-year, intensive, behavioral, weight mana...
Combustion synthesis has been used to produce Fe-(Ti,W)C composites. A simple reactor was designed which made it possible to ignite the samples under controlled atmosphere. Samples with different W/Ti ratio were ingnited under argon atmosphere by an electric arc and a self-propagating reaction was initiated in each sample. Different composites such as WC in Fe-Ti matrix, WC+(Ti,W)C in Fe matrix...
AIM This study aimed to explore the associations between abdominal obesity, inflammatory markers and subclinical organ damage in 740 middle-aged patients with type 2 diabetes. METHODS Waist circumference (WC) and sagittal abdominal diameter (SAD) were measured, and blood samples were analyzed for C-reactive protein (CRP) and IL-6. Carotid intima-media thickness (IMT) was evaluated by ultrason...
OBJECTIVE To validate the application of an automated neuronal spike classification algorithm, Wave_clus (WC), on interictal epileptiform discharges (IED) obtained from human intracranial EEG (icEEG) data. METHOD Five 10-min segments of icEEG recorded in 5 patients were used. WC and three expert EEG reviewers independently classified one hundred IED events into IED classes or non-IEDs. First,...
