بررسی تحلیلی اهمیت انحرافهای تورمی ارزش افزوده اقتصادی و تأثیر خصوصیات مالی شرکتها براین انحرافها
ارزیابی عملکرد بنگاههای اقتصادی بهمنظور اطمینان از تخصیص بهینه منابع محدود امری مهم و حیاتی بهشمار میآید و در صورتیکه از معیارهای مناسب برای اندازهگیری عملکرد و ارزش سهام شرکت استفاده نشود، ارزش شرکت به سمت ارزش واقعی آن سوق پیدا نمیکند و تخصیص سرمایه بهدرستی صورت نمیگیرد. این موضوع در شرایط تورمی از حساسیت بیشتری برخوردار است. هدف این پژوهش بررسی انحرافهای تورمی ارزش افزوده اقتصادی (...
The influences of barrier properties of packaging materials and storage conditions on selected quality attributes of carrot samples processed by pressure-assisted thermal processing (PATP) were investigated. Baby carrots were packaged in three different pouches made of multilayer films (Nylon/EVOH/EVA, Nylon/EVA and MetPET/PE) and processed at 600 MPa and 110 °C for 10 minutes. Processed pouche...
BACKGROUND Objective assessment methods to monitor residual limb volume following lower-limb amputation are required to enhance practitioner-led prosthetic fitting. Computer aided systems, including 3D scanners, present numerous advantages and the recent Artec Eva scanner, based on laser free technology, could potentially be an effective solution for monitoring residual limb volumes. PURPOSE ...
The release kinetics of dihydroetorphine (DHE) from pressure-sensitive adhesive (PSA) tape with an ethylene-vinyl acetate co-polymer (EVA) membrane as a diffusion-controlling membrane and its protective effect from an unpredictable increase in skin permeation of DHE caused by stratum corneum damage were investigated. The DHE flux through the EVA membrane was enhanced with the increase of vinyl ...
Many SLC26A4 mutations have been identified in patients with nonsyndromic enlarged vestibular aqueduct (EVA). However, the roles of SLC26A4 genotypes and phenotypes in hereditary deafness remain unexplained. This study aims to perform a meta-analysis based on the PRISMA statement to evaluate the diagnostic value of SLC26A4 mutant alleles and their correlations with multiethnic hearing phenotype...
Mouthguards (MGs) made from poly(ethylene-co-vinyl acetate) (EVA) are widely used in contact sports to prevent injuries such as breaking teeth and lip lacerations and to reduce brain concussion. However, the changes in morphology and the molecular mobility of EVA, which can affect its physical properties during practical usage, have not been precisely examined. Therefore, we attempted to determ...
Repeated oral administration of mexazolam, an anti-anxiety agent, may cause adverse effects such as gastric disturbance, drowsiness, and ataxia due to transiently high blood levels. Transdermal administration would avoid the systemic side effects and gastric disorders after oral administration. We have developed a matrix using ethylene-vinyl acetate (EVA), a heat-processible and flexible mat...
