The use of dioxy MP 14 (stabilized aqueous chlorine dioxide) to control environmental airborne microorganisms

Mbamalu, Oluchi Nneka January 2009 (has links)
Magister Pharmaceuticae - MPharm / Dioxy MP 14 is a locally developed form of stabilized chlorine dioxide in an aqueous medium. It has all the sanitizing properties of chlorine dioxide gas, a neutral compound of chlorine in the +IV oxidation state, which has been used extensively as a non-toxic sterilizing agent with various applications. In this study, Dioxy MP14 was tested in a commercial chicken pen to determine its effectiveness as an environmental sanitizing agent. Control of environmental microbes in a chicken pen is important to ensure healthy birds and optimum egg production. The biocide was introduced via an overhead misting system with a variable dosing pump at various daily frequencies.The effectiveness of environmental microorganism control was determined with air settle plates. The health and performance of the chickens were evaluated and compared to chickens in a control pen.The results show a decrease in airborne microbial load in the treated pen. Better egg production and lower mortality of the chickens in the treated pen compared to the control pen, indicate effective environmental microbial control was achieved with a residual 7.46 ppm Dioxy MP 14 at a daily dose given for 5 minutes every 2 hours.This study was a pilot study, with encouraging results, for an extended study to investigate the feasibility of introducing Dioxy MP 14 through a misting system in a clinical environment (clinics and hospitals) to control airborne pathogens like Mycobacterium tuberculosis thereby reducing the infection risks for clinical workers and medical staff.

Automaticky ovládané akvárium pro simulaci klimatických podmínek v deštném pralese / Automatic control of aquarium dedicated to simulation of the conditions in rain forest

Petrucha, Martin January 2014 (has links)
This work deals with designing complete equipment of paludarium. Selection of individual components to simulate jungle conditions and automate the process of maintaining the forest conditions in a closed environment. All components of the project will be automatically controlled to maintain a user-set conditions inside paludariums. The measured data will be stored on the SD card.
