Providing a programming lab to a large group of students requires a lot of effort. Often in these cases additional staffing is required to provide students with enough feedback on their work. However, due to resource constraints this is not always possible. This paper presents Athena, a lab support tool that reduces the effort required for programming labs and provides students with adequate an...

This report is an evaluation of the selenium removal from agricultural drainage water and synthetic solutions contaminated with high amounts of selenium. Batch and kinetic studies were conducted on the removal of selenium and the effectiveness of various remediation materials was determined. The agricultural drainage water samples were obtained from San Joaquin Valley and provided by Department...

Lehnert R., Novák P., Macieira F., Kuřec M., Teixeira J.A., Branyik T. (2009): Optimisation of labscale continuous alcohol-free beer production. Czech J. Food Sci., 27: 267–275. In order to study the formation and conversion of the most important flavour compounds, the real wort used in alcohol-free beer fermentation was mimicked by a complex model medium containing glucose, yeast extract, and ...

homogenizer and ultrasonicator that we call as mechanical methods were used in the lab scale production of alcohol free reduced glutathione (alcohol free gsh) from baker’s yeast. the study was done to determine the effects of specific parameters of the methods and the ph of the medium on the production of the gsh. the cell disruptions were run at a wide range of those parameters at the suitable...

This study is focused on the removal of pentachlorophenol from its aqueous phase by electrochemically induced degradation with Pt electrodes. The objective of this study was to contrast the electrochemical removal of pentachlorophenol at the oxidative and the reductive potentials, and further to understand how to apply the electrochemical treatment on PCP degradation. Lab experiments were condu...

We describe interfaces and visualizations in the CRAIVE (Collaborative Research Augmented Immersive Virtual Environment) Lab, an interactive human scale immersive environment at Rensselaer Polytechnic Institute. We describe the physical infrastructure and software architecture of the CRAIVE-Lab, and present two immersive scenarios within it. The first is “person following”, which allows a perso...

coustic emission (AE) techniques have been used * of arrival-time differences (delta-T’s) for each mesh point. To in the study of crack location, cracking mecha‘ calculate the source position for a set of burst-type AE signisms, deformation of metals and leak detection. : nals, a straightforward “shift and a d d method was used. A In these techniques, AE sensors hit by transient . First, assumi...

Computers have assumed an increasingly important role in the educational process, and consequently, institutions of higher learning have sought to enhance the quality of computer access they provide on their campuses. Based on a study of student computer users at a large state university, this paper reports the purification of a psychometric scale designed to assess the service quality of campu...

BACKGROUND Wheat straw used for bioethanol production varies in enzymatic digestibility according to chemical structure and composition of cell walls and tissues. In this work, the two biologically different wheat straw organs, leaves and stems, are described together with the effects of hydrothermal pretreatment on chemical composition, tissue structure, enzyme adhesion and digestion. To highl...
