Map-based methods for estimating glacier equilibrium-line altitudes
We examine the validity of two methods for estimating glacier equilibrium-line altitudes (ELAs) from topographic maps. The ELA determined by contour inflection (the kinematic ELA) and the mean elevation of the glacier correlate extremely well with the ELA determined from mass-balance data (observed ELA). However, the range in glacier elevations above sea level is much larger than the variation ...
متن کاملEarly life adversity is associated with a smaller hippocampus in male but not female depressed in-patients: a case–control study
BACKGROUND Three studies assessed the association of early life adversity (ELA) and hippocampal volumes in depressed patients, of which one was negative and the two others did not control for several potential confounding variables. Since the association of ELA and hippocampal volumes differ in male and female healthy volunteers, we investigated the association of ELA and hippocampal volumes in...
متن کاملEffects of early life adversity on cortisol/salivary alpha-amylase symmetry in free-ranging juvenile rhesus macaques.
Early life adversity (ELA) affects physiological and behavioral development. One key component is the relationship between the developing Hypothalamic-Pituitary-Adrenal (HPA) axis and the Sympathetic Nervous System (SNS). Recent studies suggest a relationship between early life adversity and asymmetry in cortisol (a measure of HPA activation) and salivary alpha-amylase (sAA: a correlate of SNS ...
متن کاملتعیین ارتفاع خط تعادل (ELA) در دره‌ی هراز در آخرین دوره‌ی یخچالی
گسترش و بسط نظریه‌ی یخبندان کواترنری به وسیله‌ی تجزیه و تحلیل داده‌ها و یافتن ارتباط میان جهت و ارتفاع ناهمواری و چگونگی پدید آمدن اشکال مورفولوژی یخچالی هدفی است که این تحقیق بنیادی در تلاش برای نیل به آن است. بر این اساس، اهداف فرعی زیر مطرح می‌شوند: الف) شناخت اشکال مورفولوژی یخچالی در دره‌ی هراز؛ و ب) تعیین مرزهای یخچالی کواترنری در البرز مرکزی. دره‌ی هراز، از دامنه‌ی آزادکوه تا دره‌ی اصلی ...
متن کاملThe feasibility and safety of thoracoscopic surgery under epidural and/or local anesthesia for spontaneous pneumothorax: a meta-analysis
The aim of this study was to compare thoracoscopic surgery for spontaneous pneumothorax under epidural and/or local anesthesia (ELA) with that under general anesthesia and prove the feasibility and safety of thoracoscopic surgery under ELA for spontaneous pneumothorax. Relevant studies were searched in five databases from their date of publication to June 2016. We collected and analyzed the dat...
متن کاملAn unparalleled scientific resource endangered.
N half a century ago, a unique resource for freshwater research was created. The Experimental Lakes Area (ELA) consists of 58 lakes and their drainage basins in Ontario, Canada. The ELA was designed to allow whole-lake manipulation experiments; in addition, unperturbed ELA lakes have been monitored for the past 44 years. There is no other facility in the world that allows for the study of physi...
