a method to quick detect concentration of lecithin in eggs, namely microwave digestion spectrophotometry, was established in this research. the homogenate of eggs was treated with absolute ethanol to eliminate phosphate protein in eggs which could possibly affect concentration of lecithin examined. a sample then received a new way of pre-treatment, called microwave digestion, before uv-vis spec...

The microwave absorbing characteristics of magnetic separation products (magnetic and non-magnetic) of reductive products of ilmenite concentrate were measured by the method of microwave cavity perturbation and the magnetic separation products were characterized by X-Ray Diffraction (XRD). It was demonstrated that metallic iron was a strong microwave absorbing material, while TiO2 was a weak mi...

Introduction: Recent increase of endocrine disorders may be correlated to the increased exposure to electromagnetic fields from various instruments. Radiation leakage from microwave oven may be harmful for users. Ladies have the highest levels of contact with microwave ovens. This study was carried out to evaluate the effect of radiation leakage from microwave oven on body weight, cortisol a...

Hyssopus of­ficinalis L. is one of the most important medicinal plants. Medicinal herbs are contaminated by microorganisms. Conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

Individual, living, tissue cells can be obtained in suspension by digesting with trypsin the clot of growing tissue cultures. Under these circumstances the living cells assume a spherical form. When washed and plated in fresh plasma they put out processes and proliferate. After growth in the new plates has occurred the digestion and plating can be repeated. The limits of the method have not yet...

The amounts of carboxymethyl cellulase present in the midguts and hindguts of two species of cockroaches were determined. Numbers of colonies from the guts which digested carboxymethyl cellulose, visualized by flooding plates with cetyltrimethylammonium bromide after incubation, were counted. The numbers indicated the presence of a resident, multiplying population of predominantly anaerobic car...

A heat-stable raw-starch-digesting amylase (RSDA) was generated through PCR-based site-directed mutagenesis. At 65 degrees C, the half-life of this mutant RSDA, which, compared with the wild-type RSDA, lacks amino acids R178 and G179, was increased 20-fold. While the wild type was inactivated completely at pH 3.0, the mutant RSDA still retained 41% of its enzymatic activity. The enhancement of ...

abstract during these protracted years, mankind’s main foods consist of grains-specially wheat, oats and rice. granary production and its storage have been one of the main concerns of a human being for a long time. microwave radiation as a safe insect control agent could secure high mortality rate of insect population by increasing the temperature of insects’ body and its niche. low temperature...
