Comparative Microbiological Analysis of Water Stored in Different Storage Vessels
ثبت نشده
چکیده
Water is most essential for existence of life on earth. Water is the basic necessity of all living creatures and its important use are for drinking purpose. Water intended for human consumption must be safe and free from microbes. Therefore this investigation was taken with the objective to study the effect of storage of lake water in different vessels like plastic, clay, copper and stainless steel by comparing the number of coliforms present in the water before and after storage. The findings may have significant implications in the use of vessels made of copper and its alloys for household storage of drinking water.

Comparative Evaluation of Some Properties of Chicken and Japanese Quail Eggs Subjected to Different Storage Methods
This study investigated the potential effects of egg quality indices at 95% confidence level in order to minimize quality loss during different storage conditions. The chicken and quail eggs’ quality indices including weight, albumen index, yolk index, Haugh index in fresh eggs as well as after storing in moist sawdust, oil, and refrigerator were measured for six weeks. The results revealed tha...

متن کاملA Numerical Investigation into the Effect of Controllable Parameters on the Natural Gas Storage in a Weak Reservoir-type Aquifer
Natural gas storage process in aquifer, due to fluid flow behavior of gas and water in the porous medium and because of their contact with each other under reservoir conditions, faces several challenges. Therefore, there should be a clear understanding of the injected gas behavior before and after the injection into the reservoir. This research simulates the natural gas storage in aquifer by us...
متن کاملEffect of Benzyladenine and Gibberellic Acid on Dormancy Breaking, Growth and Yield of Gladiolus Corms over Different Storage Periods
A study was conducted to determine the optimum concentration of benzyladenie (BA) and gibberllic acid (GA3) to break the dormancy of gladiolus corms in relation to storage period and to find out the effect of BA and GA3 on growth and development of gladiolus corm and cormels. The effect of GA3 on dormancy breaking was most pronounced in the 100 ppm treatment being 26.93 days while in the water ...
