Displacement of oxygen by an inert gas is a method for attaining anaerobiosis which is preferred by many bacteriology laboratories because of the low cost of the process, and because of the small but real danger of explosion when the alternative, hydrogen with ignition, is used. Several cycles of evacuation and filling are necessary; usually, oxygen-free nitrogen is used with a final charge of ...

Several parameters on the oviposition site preference of Aedes albopictus were studied, including color, container type, salinity, and water type. Dark-colored glass jars, especially black, blue, and red ones were preferred over light-colored jars. The black-colored ovitrap with a paper strip performed better than other types of containers. Seasoned tap water had the highest egg count when comp...

On 31 July 2003 BfR provided information on the occurrence of semicarbazide (SEM) as a contaminant in various foods. This was based on information from the European Food Safety Authority (EFSA). The common feature of these foods was that they were packaged in glass jars or bottles. Initial study results indicated a semicarbazide content of up to 15 μg/kg food. One possible source given for semi...

We developed three types of covers that are easily fabricated from plastic screen locally manufactured in Thailand. The covers were designed to permit normal use of water jars for drinking, utility water uses, and water storage. Tests of the covers in the laboratory and field demonstrated that they could completely prevent successful development of Aedes aegypti (L.) in water jars. Initial expe...

The coinage of the Sasanian Empire (224-651 CE) is not only the most important primary source for its monetary and economic history, but also of greatest relevance for its history and art history.Coin hoards are of pivotal importance for studying Sasanian coinage. On August 29,2007,two jars were unearthed during the construction work for the new border sentry post of “Havār-Barxāh-loh” in the P...

It is approximated that there will be a considerable amount of increase in worlds energy needs. So, need high storing devices when the load low or moderate. Supercapacitors (SC) can competent options to serve this purpose. The paper recounts performance supercapacitors churned out from horizontal axis multi-jar ball milling machine based on variations material properties jars. To store ample en...
