1. The determination of the influence of temperature on the velocity of a photochemical reaction is always of importance. This is particularly true when the mechanism of the reaction is unknown, as in the present instance of the bleaching of visual purple. The usefulness of determining the temperature coefficient lles in this. Photochemical reactions have low temperature coefficients.near unity...

the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...

This paper introduces some of the research behind automatic scoring of the speaking part of the Arizona English Language Learner Assessment, a large-scale test now operational for students in Arizona. Approximately 70% of the students tested are in the range 4-11 years old. We cover the methods used to assess spoken responses automatically, considering both what the student says and the way in ...
Previous studies have shown that intraindividual variability (iV) in performance is an important indicator of individual’s cognitive functioning and neurological integrity. While most experiments have examined iV of performance using Reaction Time data (RTs), few studies have considered it with accuracy measures (e.g. number / percentage of correct responses). For these two types of measures, i...
Soil property mapping is commonly done in two dimensions, and variation by depth is ignored. The only way to consider the vertical variation is mapping in 3D. In this paper, we present a method based on polynomial depth functions. The objective is determining the effectiveness of a simple polynomial to predict cone-index data by depth over a field. In order to study the performances of the prop...
Transient and steady-state multiphysics numerical simulations are performed to investigate the thermal and electrical performances of a thermoelectric generator (TEG) module placed between hot and cold blocks. Effects of heat radiation, leg length and Seebeck coefficient on the TEG thermal and electrical performances are identified. A new correlation for the Seebeck coefficient with temperature...
