glycerol mono-oleate (gmo) was produced by direct esterification reaction with amberlyst 16 resin catalysts with the efficiency of 86% and was used as a surfactant for synthesis of cofe2o4 nano-particles by surfactant-assisted microwave method. fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem) were used to consider the structural and...

Traditionally the machine-learning community has viewed the No Free Lunch (NFL) theorems for search and optimization as a limitation. We review, analyze, and unify the NFL theorem with the perspectives of ``blind"" search and meta-learning to arrive at necessary conditions for improving black-box optimization. We survey meta-learning literature to determine when and how meta-learning can benefi...

A growing body of research has focused on so-called 'utilitarian' judgments in moral dilemmas in which participants have to choose whether to sacrifice one person in order to save the lives of a greater number. However, the relation between such 'utilitarian' judgments and genuine utilitarian impartial concern for the greater good remains unclear. Across four studies, we investigated the relati...

In this analysis, the economics of MBI International’s three-phase surfactant washing system for the removal of polychlorinated biphenyls (PCBs) from sediment was optimized. The system, which consists of a screw washer, an oil/water separator, and a vacuum filter, transfers PCBs to a sacrificial oil layer through two individual two-phase partitioning steps. At the completion of the washing proc...

A salophen cobalt(II) complex enables water oxidation at neutral pH in photoactivated sacrificial cycles under visible light, thus confirming the high appeal of earth abundant single site catalysis for artificial photosynthesis.

Marine structures are one of the most important and susceptible facilities in Iran due to corrosion. The two methods of Cathodic Protection, namely, the cathodic protection with sacrificial anodes and cathodic protection using impressed current, are widely used for corrosion protection. According to the former, sacrificial anodes are installed at several points in the structure. Position of the...
