Methods: The procedure consists of reducing any restorations, caries or debris. The clean and dry tooth, mostly dentin, is immediately grinded using a specially designed 'Smart Dentin Grinder'. The dentin particulate of 300-1200 um is sieved through a special sorting system. The sorted particulate dentin is immersed in basic alcohol cleanser in a sterile container to dissolve all organic debris...
Cellulase and xylanase production from rice straw using M.thermophila SH1 was assessed. The waste was dried, grinded to mesh size of 2.0mm and microwave pretreated. The powdered waste was than used as a substrate. Fermentation was carried out in flasks containing pretreated and untreated rice straw, vogel;s medium, cultured at 50C initially for 8 days to verify cellulase production and for 5 da...
Flavonoids are the biggest compound from phenolic group that has function of antioxidants. One plants with flavonoids is patat (Phrynium capitatum), which usually used as food wrapping material. This study aims to quantify total flavonoid content, antioxidant activity and identify leaves ethyl acetate extract. Patat sample cleaned, dried, grinded. Grinded were macerated gradually for 2 × 24 hou...
Recycled Concrete Aggregates (RCA) are not enough used in the construction sector due to their high porosity and water absorption capacity. Fine particles which composed of large amounts attached hardened cement paste even more difficult valorize, while they could be as mineral admixture mortar or concrete. The objective this work is find a recovery track for material addition. use porous powde...
Filtration drying of grinded sunflower stems as the unit operation technological line for solid biofuel production has been proposed. Theoretical aspects heat transfer processes during filtration have analyzed. The effect agent velocity increase from 0.68 to 2.05 m/s on intensity established. values coefficients calculated basis thin-layer experimental data and equation . Calculated correlated ...
A labour- and time-effective analytical procedure for determination of ivermectin in medicated feed at recommended level of 2.0 mg kg(-1) has been developed and validated. The analyte was extracted from grinded feed samples with acetonitrile and derivatisated with N-methylimidazole and trifluoracetic anhydride. The fluorescent derivatives were analysed by liquid chromatography method using C8 c...
We consider the problem of the automatic inspection of industrial metal pieces. The purpose of the work presented in this paper is to derive a method for defect detection. For the first time in this context we adapt level set method to distinguish hollow regions in the metal pieces from the grinded surface. We compare this method with Canny edge enhancement and with a thresholding method based ...
