Abstract: Dissolution and recovery of Mn-Al compacts with and without a chloride flux was studied by taking samples from the melt after addition of the compact. Events occurring after the addition of the compacts into the melt were studied using water quenched specimens after holding them for a specified time in molten state. The cross sections of these specimens were characterized by SEM a...

There is a demand for reduced power consumption in the vapor compression refrigeration cycle. Coefficient of performance of window-air conditioners considerably decreases and power consumption increases under very hot conditions. These problems have encouragecl studies aimed at improving the performance of window-air-conditioners by enhancing the heat transfer rate in the condenser. In this ar...

This empirical study is mainly devoted to comparing four tree-based boosting algorithms: mart, abc-mart, robust logitboost, and abc-logitboost, for multi-class classification on a variety of publicly available datasets. Some of those datasets have been thoroughly tested in prior studies using a broad range of classification algorithms including SVM, neural nets, and deep learning. In terms of t...

dpph radical-scavenging activity of the bene hull oil (bho), sesame oil (seo), rice bran oil (rbo), the oils' methanolic (ch3oh/h2o, 80:20 v/v) or hexane extracts, and their unsaponifiable matters fraction were measured and compared with each other. as a radical-scavenger, seo was significantly stronger than rbo and bho, respectively. unlike bho and rbo, the unsaponifiable (usm) fraction of the...

Abstract The harmonic inversion (HI) problem in nuclear magnetic resonance spectroscopy (NMR) is conventionally considered by means of parameter estimations. It consists extracting the fundamental pairs complex frequencies and amplitudes from encoded time signals. This linear nonlinear that are entrenched damped exponentials (harmonics) within signal. Nonlinear problems usually solved approxima...

Single oral dose trimethoprim pharmacokinetics were determined in 18 children aged 3 months to 13 years. Trimethoprim suspension was rapidly absorbed and quickly and widely distributed. The mean clearance was considerably faster and the elimination half life considerably shorter than values reported in adults. Only one third of the administered drug dose was recovered from the urine within 24 h...
