the photocatalytic decolorization of aqueous solutions brown ng, a commercial textile dye, was studied using titana degussa p-25 as a catalyst for the first time. the experiments were carried out in a batch reactor with the use of artificial light sources (uv-c). the effects of various process variables on decolorization performance of the process have been investigated. the photodegradation of...

An Instrumented task board has been developed at NASA Marshall Space Flight Center (MSFC). An overview of the task board design, and current development status is presented. The task board was originally developed to evaluate operator performance using the Protoflight Manipulator Arm (PFMA) at MSFC. The task board evaluates tasks for Orbital Replacement Unit (ORU), fluid connect and transfers, ...

This paper introduces a model for blu¢ng that is relevant when bets are sunk and only actions -not valuationsdetermine the winner. Predictions from poker are invalid in such nonzero-sum games. Blu¢ng (respectively Sandbagging) occurs when a weak (respectively strong) player seeks to deceive his opponent into thinking that he is strong (respectively weak). A player with a moderate valuation shou...
