Kinetics and selected variables (temperature, particle size and time) for extraction of Terminalia Catappa L Kernel Oil (TCKO) were investigated using solvent extraction. Kinetic models studied were: parabolic diffusion, power law, hyperbolic, Elovich and pseudo-second-order. In ascending order, the best-fitted models at the optimum temperature and oil yield were Elovich’s model, hyperbolic...

According to prevailing theory and anecdotal evidence, the congruence between institutional attributes and students’ needs, interests, and preferences plays a key role in promoting college satisfaction and retention. However, this assertion has received little direct empirical attention, and the few available studies appear to have some key limitations. This study examined the factor structure ...

The temperature dependence of the complex dielectric function ϵ1+iϵ2 bulk Ge near direct bandgap was investigated with spectroscopic ellipsometry at temperatures between 10 and 710 K. Second derivatives respect to energy are obtained using a digital linear filter method. A model that incorporates excitonic effects Tanguy for Hulthén potential [C. Tanguy, Phys. Rev. B 60, 10660 (1999)] used fit ...

Objective: The aim of this study was to investigate the direct and indirect roles of psychiatric symptoms, social support, and meaning in life in predicting internet addiction among university students. Methods: The study was performed in a cross-sectional design by employing the path analysis to explore the model fitting. All the students at Kerman University of Medical Sciences constituted t...

papermill sludge (pms) is the waste product from the paper manufacturing industry and is produced in considerable quantities worldwide. this investigation characterised a pms from a papermill plant in south africa and investigated the potential for direct land application of the pms to soil. in a pot experiment, application of pms to three contrasting soils at equivalent rates of 0, 10, 20 and ...
