An example of InAsSbP quaternary quantum dots (QDs), pits and dots-pits cooperative structures' growth on InAs(100) substrates by liquid phase epitaxy (LPE) is reported. The interaction and surface morphology of the dots-pits combinations are investigated by the high-resolution scanning electron microscope. Bimodal growth mechanism for the both QDs and pits nucleation is observed. Cooperative s...

A biofilter inoculated with Arthrobacter sp. was applied to the simultaneous elimination of trimethylamine (TMA) and ammonia (NH3) from the exhaust air of swine waste storage pits. The results showed that the biofilter achieved average removal efficiencies of 96.8+/-2.5% and 97.2+/-2.3% for TMA and NH3, respectively. A near-neutral pH (7.3-7.4) was maintained due to the accumulation of acid met...

Experiments about single pit initiation and propagation were performed on 316L stainless steel with the aim to determine the pitting corrosion behaviour for nuclear waste containers. The experimental setup permits to control the pit development at will and to create reproducible single pits in three dimensions. Radial and deep evolutions of a disc shaped pit were studied for propagation times o...

the yield and quality features of raisin are affected by various factors especially har-vest date and dipping solutions. combinations of different harvest date (four harvest dates) and post harvest alkaline emulsion (three alkaline solutions) were tested in vitis vi-nifera l. cv ‘paycamy’ green raisin production in kashmar, khorasan province of iran. such raisin quantitative and qualitative cha...

background: in algeria the date wastes production is estimated at least 85.000 tones. date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced.objective: the aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. materials...
