Water is life, and without water, there would be no civilizations a vacant Earth. considered an abundant natural resource on the earth. covers 3/4 of surface. However, 97% available water earth salty oceanic only tiny fraction (3%) freshwater. This small portion supplies needs humans animals. freshwater exists in underground, rivers, lakes insufficient to cover all world’s demands. Thus, saving...

An ODYSSEY autonomous underwater vehicle (AUV) was deployed in Massachusetts and Cape Cod Bays in September 1998 to collect chlorophyll fluorescence, optical backscattering (880 nm), and physical data. It sampled the region mainly in a sawtooth pattern with horizontal resolution between B120m at the middle of the water column and with vertical resolution of 0.1m. The data were used to quantify ...

The freezing of water to ice is a classic problem in applied mathematics, involving the solution of a diffusion equation with a moving boundary. However, when the water is salty, the transport of salt rejected by ice introduces some interesting twists to the tale. A number of analytic models for the freezing of water are briefly reviewed, ranging from the famous work by Neumann and Stefan in th...

SuperCritical Water Oxidation (SCWO) process is investigated at the Institut of Technical Chemistry, ITC-CPV. The objectives were to determine destruction efficiencies of model compounds and industrial waste effluents and to study the feasability of the SCWO process. Two continuous SCWO bench scale plants are operated: a pipe reactor and a transpiring wall reactor system (design data: T = 630 °...

Abstract Agulhas leakage, the warm and salty inflow of Indian Ocean water into Atlantic Ocean, is importance for climate-relevant Meridional Overturning Circulation. South Africa, eastward turning Current sheds rings, cyclones filaments order 100 km that carry Cape Basin further Atlantic. Here, we show resolution submesoscale flows 10 in an ocean model leads to 40 % more leakage realistic water...

In this work, we studied the distribution and group dynamics of Aedes species in region Biskra, which were essentially formed by three caspius, detritus, dorsalis, as well physicochemical characteristics their breeding sites. The results showed that caspius was most abundant all sites surveyed, with a rate 66.43% total fauna indicated. While remaining two mosquito have different rates during st...
