The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...
this study aimed to examine the effectiveness of combined microwave-ultrasonic pasteurization system on escherichia coli and vitamin c content in sour cherry juice (scj). based on the findings, microwave output power, ultrasound power, and ultrasonic exposure time as well as the microwave-induced temperature were the most effective factors in reducing e. coli and vitamin c content. in addition,...
in the present study, aminoazines were prepared from the reaction of amidrazone hydroiodide with various aromatic aldehydes in the presence of a solid base under microwave irradiation with power level of 850 w for 2-7 min in high yields. the amidrazone hydroiodide can also be prepared by the reaction of s-methyl isothiobenzamide hydroiodide and hydrazine in methanol under nitrogen gas. all synt...
in this pepper fe2o3 nanoparticles were synthesized via a fast microwave method. then fe2o3-tio2 nanocomposites were synthesized by a sonochemical-assisted method. the prepared products were characterized by x-ray diffraction pattern, scanning electron microscopy and fourier transform infrared spectroscopy. the photocatalytic behaviour of fe2o3-tio2 nanocomposites was evaluated using the degrad...
In the Panegyrics of saint Gorgon, Bossuet uses topics eating and drinking, changes its meaning under paradigm catholic dogma : it doesn't help any more to express humiliation, but greatness christianism. This paradoxical construction christian sublime forms bedrock an approach language as digesting topical raises legendary aspect narrative martyrdom - a border case fiction -, which is itself c...
An endospore-forming thermophilic bacterium, which produced amylase and was identified as Bacillus stearothermophilus, was isolated from soil. The amylase had an optimum temperature of 70 degrees C and strongly degraded wheat starch granules (93%) and potato starch granules (80%) at 60 degrees C.
the cost of drying carpet which is done toward the end of the manufacturing process, is quite high. the carpet industry has been using convection drying for many years. little attention has been given to quantifying the effect of microwave power during the drying of carpet. an experimental system was developed whereby air was introduced into the cavity of a domestic microwave oven. the results ...
Alteromonas-like strains KMM 241(T) and KMM 642, isolated from marine invertebrate specimens, were investigated to clarify their taxonomic position. The novel isolates were aerobic, Gram-negative, motile, slightly halophilic and heterotrophic and hydrolysed polysaccharides. They did not hydrolyse urea, gelatin or casein and produced acid weakly from carbohydrates. The DNA G + C content ranged b...
