Evaporation estimates are often used in water balance calculations to determine seepage rates from feedyard holding ponds and lagoons. These estimates have been made using empirical equations derived for clear water, Class A Pan evaporation measurements using clear water, and rule-of-thumb estimates. However, feedyard effluent has different physical and chemical characteristics than clear water...

Hepatorenal failure, a well-recognized complication of established liver disease, is characterized by early renal hemodynamic changes (vasoconstriction) before clinically recognized kidney disease. This renal vasoconstriction (increased renal vascular resistance) should be detectable noninvasively by Doppler ultrasonography. We studied whether renal Doppler ultrasonography detects abnormalities...

BACKGROUND Perioperative hypothermia is common during anesthesia and surgery and is accompanied by several complications. Forced-air warming is recognized as an effective procedure to prevent hypothermia. The aim of this study was to compare a resistive heating device with a forced-air warming device. METHODS Prospective randomized trial. SETTING heat transfer laboratory of a University hos...

A resistive control strategy to optimize pneumatic power for a floating OWC device is presented. This strategy utilizes a linear, frequency-domain performance model that links an oscillating structure to air-pressure fluctuations with a Wells Turbine in 3-dimensions. An array of field points defining the interior free surface allows hydrodynamic parameters relating to the fluctuating air-pressu...

© Appl. Rheol. 15 (2005) 390–397 Abstract: We report on the design and implementation of an evaporation blocker for cone-plate and plate-plate geometries. In addition to minimizing sample evaporation by trapping the saturated vapor inside a sample chamber, an important feature of the evaporation blocker is the suppression of solvent transport through condensation. Validation tests with DI-water...

Electromagnetic scattering is considered from finite and electrically large perfectly conducting rough surfaces. Three solution approaches are considered. The first two are based on a multi-level fast-multipole algorithm (MLFMA) formulation. In one MLFMA approach the rough surface resides in free space and is terminated by a resistive taper. In the second MLFMA approach the rough surface is ter...

the aim of this study was to prepare liposomes of acyclovir (acy) by thin layer evaporation (tle) and reverse phase evaporation (rev) methods. twenty-seven batches of liposomes from each method were prepared using technique of three variables at three levels (33) factorial design. drug/lipid (molar ratio), hydration volume and hydration time were considered three independent variables in tle me...

effect of seed priming on germination and seedling growth of sesame investigated under controlled conditions. the primed seeds with znso4 had the maximum germination percentage whereas the highest germination rate was observed in hydro-primed seeds. the treated seeds with peg showed the best growth of the seedlings and rootlet. the complementary field experiment was conducted to evaluate the ef...

A striking universality in the electric-field-driven resistive switching is shown in three prototypical narrow-gap Mott systems. This model, based on key theoretical features of the Mott phenomenon, reproduces the general behavior of this resistive switching and demonstrates that it can be associated with a dynamically directed avalanche. This model predicts non-trivial accumulation and relaxat...

Here, we propose an effective method for improving the resistive switching characteristics of solution-processed gallium-doped zinc oxide (GaZnO(x)) resistive random access memory (RRAM) devices using hydrogen peroxide. Our results imply that solution processed GaZnO(x) RRAM devices could be one of the candidates for the development of low cost RRAM.
