Application Of Ozonated Water Technology For Improving Quality And Safety Of Peeled Shrimp Meat, Amrish Suresh Chawla Jan 2006

Application Of Ozonated Water Technology For Improving Quality And Safety Of Peeled Shrimp Meat, Amrish Suresh Chawla

LSU Master's Theses

Ozone is an effective sanitizing agent against a broad spectrum of pathogenic and spoilage organisms. Optimization of treatment applications of ozonated water is needed for increased use in the food industry. An experimental apparatus and process has been developed to digitally measure ozone concentrations in processing water at the point of product application. Two application methods were evaluated. Ozone concentrations were measured rapidly at the point of product application. Shrimp samples were either sprayed or soaked for 20, 40 or 60 seconds with similar volumes of water with dissolved ozone levels of 1, 2, or 3 ppm. Microbial destruction using …


Effect Of Speed Limit Increase On Crash Rate On Rural Two-Lane Highways In Louisiana, Athira Swarna Jayadevan Jan 2006

Effect Of Speed Limit Increase On Crash Rate On Rural Two-Lane Highways In Louisiana, Athira Swarna Jayadevan

LSU Master's Theses

Though the rural two lane roads are the low volume-less traveled roads, the majority of the crashes occur on these roads and the high speed of motor vehicles on these roads is suspected to be one of the main causes for this. This study focused on the development of a methodology to study the impact of a speed limit increase on the crash rate on the rural two lane roads in Louisiana. The Louisiana crash database obtained from the Louisiana Department of Transportation (LADOTD) was used to carry out the analysis. The analysis consisted of the comparison of crash rates …
