Application of agriculture residue especially in biochar form seems to be effective in the removal of contaminants such as nitrate pollution. The effectiveness of biochar produced from palm leaf residues (pyrolyzed at 600 ˚C) in the removal of nitrate from aqueous solution was studied at different pH. The pH value at the point of zero charges (pHpzc) and surface functional groups...

Lecture-based instructional models have been the mainstay of education for centuries. They excel primarily at delivering information from the one to the many. Educators refer to this model as "the sage on the stage". Clearly there are educators who relish this role and are strongly opposed to moving away from it. Yet, educational research and new innovative technologies are suggesting that lect...

There is a significant growth of behavior economics in the last decade. The goal of the behavior research is aimed at the deviations from rationality in order to improve the predictive power of economic models. In this paper, attached to the specific auditing process, I want to classify the neglecting relevant information due to judgment by representative which causes the bias, or the error of ...

Exposure to a patch of dots produces a repulsive shift in the perceived numerosity of subsequently viewed dot patches. Although a remarkably strong effect, in which the perceived numerosity can be shifted by up to 50% of the actual numerosity, very little is known about the temporal dynamics. Here we demonstrate a novel adaptation paradigm that allows numerosity adaptation to be rapidly induced...

An economic model of fertility choice is presented and discussed in which the utility level of agents depends upon their consumption, the number of children they have, and upon the consumption of their children. Parents are altruistic toward their children, but in a more limited sense than in the fertility model presented by Becker and Barro in 1988, in which the utility of parents depends upo...

OBJECTIVE Research on early life socioeconomic status (SES), education and mortality is less established in developing countries. This analysis aims to determine how SES and education are patterned across the life course and associated with adult mortality in Mexico. MATERIALS AND METHODS Data comes from 2001-2012 Mexican Health & Aging Study (Mexican adults age 50+, n= 11,222). Cox proportio...

This study examined the relationship between the similarity and accuracy of team mental models and compared the extent to which each predicted team performance. The relationship between team ability composition and team mental models was also investigated. Eighty-three dyadic teams worked on a complex skill task in a 2-week training protocol. Results indicated that although similarity and accur...
