BACKGROUND Static posture, repetitive movements and lack of physical variation are known risk factors for work-related musculoskeletal disorders, and thus needs to be properly assessed in occupational studies. The aims of this study were (i) to investigate the effectiveness of a conventional exposure variation analysis (EVA) in discriminating exposure time lines and (ii) to compare it with a ne...
با توجه به اینکه بهترین و ساده ترین روش برای بهبود غشاهای پلیمری، اصلاح ترکیب آنهاست، در پژوهش حاضر، غشاهای ترکیبی پلی اتیلن با چگالی زیاد (HDPE) به همراه اتیلن وینیل استات (EVA) به روش جدایی فاز با القای گرمایی تهیه شدند. اثروجود EVA بر دمای بلوری شدن HDPE در مجاورت رقیق کننده، به کمک گرماسنج پویشی تفاضلی (DSC) شناسایی شد. براساس نتایج DSC، وجودEVA اثر چندانی بر دمای بلوری شدن HDPE نداشت...
Pooled time-series, cross-sectional data on 110 Australian companies over the period 1992-1998 is employed to examine whether the trademarked variant of residual income known as economic value-added (EVA) is more highly associated with stock returns than more conventional accounting-based measures. These other measures of internal and external performance include earnings, net cash flow and res...
An extensive peel-test study was conducted to investigate the various factors that may affect the adhesion strength of photovoltaic module encapsulants, primarily ethylene-vinyl acetate (EVA), on glass substrates of various laminates based on a common configuration of glass/encapsulant/backfoil. The results show that "pure" or "absolute" adhesion strength of EVA-to-glass was very difficult to o...
EVA is an attack graph tool that allows an administrator to assess and analyze a network in a variety of fashions. Unlike other attack graph tools which just focus on visualizing the network or recommending a set of patches to secure the network, EVA goes beyond these modes to fully explore the power of attack graphs for a multitude of administrative and security tasks. EVA can be used to deriv...
EVA (http://cubic.bioc.columbia.edu/eva/) is a web server for evaluation of the accuracy of automated protein structure prediction methods. The evaluation is updated automatically each week, to cope with the large number of existing prediction servers and the constant changes in the prediction methods. EVA currently assesses servers for secondary structure prediction, contact prediction, compar...
Using pooled time-series, cross-sectional data on 110 Australian companies over the period 1992-1998 an examination is undertaken whether the trademarked variant of residual income known as economic value-added (or EVA) is more highly associated with stock returns than conventional accounting-based measures. The accountingbased measures of internal and external performance include earnings, net...
OBJECTIVE To compare visual acuity (VA) scores after autorefraction vs manual refraction in eyes of patients with diabetes mellitus and a wide range of VAs. METHODS The letter score from the Electronic Visual Acuity (EVA) test from the electronic Early Treatment Diabetic Retinopathy Study was measured after autorefraction (AR-EVA score) and after manual refraction (MR-EVA score), which is the...
IMPORTANCE Approximately one-half of all subjects with unilateral or bilateral hearing loss with enlargement of the vestibular aqueduct (EVA) will have SLC26A4 gene mutations. The number (0, 1, or 2) of mutant alleles of SLC26A4 detected in an individual subject with EVA is each associated with a distinct combination of diagnostic and prognostic information as well as probability of recurrence ...
In this study, polyvinyl alcohol- Nanofibrillated cellulose –Montmorillonite (PVA-NFC-MMT)and Ethylene-vinyl acetate- Nanofibrillated cellulose –Montmorillonite (EVA-NFC-MMT) nanocompositescontaining 2% weight of NFC and MMT were prepared by melt blending method. Then, the effect ofNFC and MMT as reinforcing materials on biodegradability, morphology, and mechanical, thermal an...
