Sex-related differences in behavior are extensive, but their neuroanatomic substrate is unclear. Indirect perfusion data have suggested a higher percentage of gray matter (GM) in left hemisphere cortex and in women, but differences in volumes of the major cranial compartments have not been examined for the entire brain in association with cognitive performance. We used volumetric segmentation o...
هر ساله وقوع باران¬ های شدید باعث ایجاد شکست در تعداد زیادی از شیب های خاکی می¬شود .در طول این باران ها، سطح آب زیرزمینی بالا آمده و باعث افزایش فشار آب منفذی و کاهش پایداری شیب می¬گردد. استفاده از زهکش های افقی روشی موثر و کم هزینه جهت کنترل پایداری شیب در این حالت می باشد. با استفاده از این زهکش ها، آب پیوسته از محیط خاک جمع آوری شده و به تبع آن فشار آب منفذی کاهش و پایداری شیب افزایش می¬یابد...
Introduction: Slope streaks, commonly dark features in the high albedo, low thermal inertia, dust-rich equatorial regions of Mars, have been observed in images from all orbiting spacecraft since Mariner 9 [1-9] and are thought to fade or brighten over time due to mantling of dust [2,3,8]. Recent studies using images from the High Resolution Imaging Science Experiment (HiRISE) camera [10] have s...
Laver belongs to the genius of Porphyra and is the most valuable seaweed in the aqua-culture industry. It contains higher iron than many other plant foods. The bioavailability of iron from laver was evaluated in a rat hemoglobin regeneration assay. Reagent-grade ferrous sulfate was used as the reference standard, and the relative biological value (RBV) for laver was expressed as a percentage of...
This paper provides a description of the methodologies and processes used for the creation of a decision/support model for land acquisition decisions on a cooperative open space project between the City of Bakersfield and other local agencies. The model uses a cost/benefit approach using components of habitat ranking, developed through an independently prepared evaluation, and estimated per acr...
Echocardiographic measurements of the left ventricular dimensions and wall thicknesses at end diastole and end systole, aortic root and left atrial dimensions, mitral valve E-F slope, left ventricular ejection fraction, percent fractional shortening of the left ventricular internal dimension, estimated left ventricular mass and percentage systolic thickening of the ventricular septum and left v...
Because the less informed incorrectly estimate asset returns, they anticipate higher returns from their risky investments. They thus over-invest in risky securities. They are rewarded by higher total portfolio returns. Too high a proportion of less informed investors lowers the return on risky assets. Equilibrium requires that the less informed’s rate of return equal the informed’s. The less in...
The present work describes a comparison of the ability of multiple linear regression (MLR) and artificial neural networks (ANN) to predict fish spatial occupancy and abundance in a mesotrophic reservoir. Models were run and tested with 306 observations obtained by the sampling point abundance method using electrofishing. For each of the 306 samples, the relationships between physical parameters...
