In densely populated countries like Italy, cremation is promoted for the final disposition of dead. However, many families still choose inhumation or entombment. ordinary (traditional) tombs, bodies skeletonize slowly and partially, often need a second disposal after exhumation. The aim this study was to experimentally test functionality new type tomb, defined as “aerated”. Aerated tombs featur...
Production of penicillin with waste mycelium Penicillium chrysogenum as the sole source of nitrogen.
In a preliminary communication (Ghosh, 1959) it was reported that fresh and wet mycelium of Penicillium chrysogenum, as obtained from a rotary filter in a penicillin plant, could be well utilized as the sole source of nitrogen for penicillin production by the mold either in shaken flask or in aerated and agitated large fermentors. The waste mycelium did not need any pretreatment whatsoever and ...
Email: [email protected] Abstract: To evaluate the diurnal and seasonal Dissolved Oxygen (DO) variations and their effects on water quality, a comprehensive study was conducted in a eutrophic polymictic reservoir under artificially aerated and non-aerated conditions. The effect of aeration among sampling locations and along the water column of DO and DO saturation and diurnal variation...
Aerated lightweight concrete have many advantages when compared with conventional concrete such as advanced strength to weight ratio, lower coefficient of thermal expansion, and good sound insulation as a result of air voids within aerated concrete. This paper is attention to classified of aerated lightweight concrete into foamed concrete and autoclaved concrete. Also, it is exhibits the raw ma...
The uptake of Na(+) and K(+) by barley seedlings grown on aerated or non-aerated solutions was studied. Plants growing in culture solution took up K(+) with high selectivity whether the solution was aerated or not. Roots of plants grown on aerated CaSO(4) and transferred to a solution of KCl and NaCl had a lower preference for K(+) than roots of plants grown on non-aerated CaSO(4). Both kinds o...
purpose: this investigation was undertaken to evaluate the potency of metarhizium anisoplea as a biological alternative to the biological control of german cockroaches. materials & methods: the fungal spores were applied against the male and female german cockroach, using two bioassay methods, viz the submerge application and the injection. the data was analysed and the mean mortality was ...
Official guidelines for the on-site treatment of domestic sewage have recently been published by the Danish Ministry of Environment as a consequence of new treatment requirements for single houses and dwellings in rural areas. This paper summarises the guidelines for vertical constructed wetland systems (planted filter beds) that will fulfil demands of 95% removal of BOD and 90% nitrification. ...
