The aims of this work were to develop a mathematical model for composting municipal solid waste (MSW), to verify the proposed model with independent experimental data and to determine the optimum values for the initial moisture content and airflow. Separated MSW (with the addition of poultry manure, mature compost and sawdust) was used as materials for laboratory simulation. The experiment was ...

The analysis and optimal design of a multi-layered microstrip sensor for measuring moisture content of ricegrain are described. The microstrip sensing structure consists of three layers: substrate, protective layer and semi-infinite grain medium. The effective dielectric constant, characteristic impedance and attenuation or insertion loss of this structure are calculated at various moisture con...

BACKGROUND The research aimed to assess the nutritional value of raw pork meat obtained from pigs on the feed containing different types of used fat. METHODS Meat was obtained from pigs fed in 4 experimental groups, from which groups A and B were given the mixture of rapeseed oil and linseed oil in the ratio of 1:2.5 or 2.3:1:0.2 (lard) as the source of fat. In group C, animals were given the...

Beekeeping products, including flower honey, are widely used in hotel and restaurant complexes. In this article, we provide data on the chemical composition of honey complexes Bilotserkiv region. Samples from different producers, which as a dessert Bilotserkivsk region, were selected for study. The first samples (№ 1) floral by located center city Bila Tserkva; 2nd served outskirts city; third ...

Reproducible flow properties for the thermoset molded resins are necessary to insure that the manufacturing conditions used, such as mold temperature, mold pressure and cure time, consistently yield a usable final product. Lot-to-lot variations in flow properties can result in material which does not mold properly and must be rejected. One quantity which can substantially influence thermoset fl...

the sorption isotherm and state diagram of sundried, golden and sultana raisins were constructed for investigation and comparison of the product stability. the isotherms were measured at 15, 25 and 35 °c using an isopiestic method and the data were modeled with gab model. glass transition temperatures of the products were measured by differential scanning calorimetery (dsc) and fitted to gordon...

sorption isotherm and thermal properties of powders were used for determining stability during storage. garlic slices with 2 mm thickness were dried, using two methods of freeze and cabinet drying. the results showed that, the density, loss of pyruvate and color changes of the freeze dried powder were less than those of the cabinet dried powder. sorption isotherm curves of the both garlic powde...

kermanshah province is the main producer of various chickpea cultivars in iran. in this study a laboratory peg-tooth thresher was employed for chickpea threshing. the effect of cylinder speed (9, 12, 15 m/s), concave clearance (12, 14, 16 mm), feed rate (80, 160, 240 kg/h) and material moisture content (5, 10, 15% w.b.) was studied on percentage of grain damage, threshing efficiency and percent...

Salmonellosis outbreaks related to consumption of raw almonds have encouraged the scientific community to study the inactivation kinetics of pathogens in this dry commodity. However, the low moisture content of the product presents a challenge for thermal control, because the time required to achieve the desired thermal inactivation of microorganisms increases sharply with reduced moisture con...
