The microflora of milk powder consists of a wide array of microorgan­ isms of which special attention is given to Bacillus endospores. Bacillus endospores survive pasteurization and spray drying and inhabit the final powder product in the dormant state indefinitely. Once the powder is re­ constituted, endospores may germinate, and through their enzymatic ac­ tivity become detrimental to quality...

I N A PREVIOUS PAPER,’ experiments on the application of erythrocyte powder in serologic laboratories were described. It was shown that erythrocyte powder may be successfully used for (1) absorption of useless and disturbing antibodies from test sera, (2) complement fixation test with strong group antibodies, and (3) preparation of “pure” antibodies by elution from the sensitized powder. The ai...

The Physicochemical characteristics of several kinds of toothpaste and natural powder samples and their antibacterial activity against Viridans streptococci bacteria have been studied in vitro. The Physicochemical analysis such as pH, conductivity, and moisture and fluoride concentration of the toothpaste and natural powder along with X-Ray Diffraction made in the consideration to indicating th...

The alumina used for the present study was purchased from Union Carbide Corp. as Linde Alumina Polishing Powder Type A. X-ray diffraction and chemical analysis of the powder shows the mineral to be a well-crystallized corundum of high purity(>~ AlzOJ). Morphologically, the powder is constituted of micrometer-sized aggregates composed of smaller particles (between 200 and 500 nm). Nitrogen adsor...

The nasal absorption of macromolecules from powder formulations and the effect of sodium carboxymethyl cellulose (CMC-Na) as a pharmaceutical excipient on their absorption were studied. Model macromolecules were fluorescein isothiocyanate-labeled dextran (average molecular weight of 4.4kDa, FD4) and insulin. The plasma concentration of FD4 after application of the powder containing 50% starch (...

The purpose of the present study was to evaluate the effects of red pepper seeds powder on lipid metabolism in rats fed high fatᆞhigh cholesterol diet. Rats were divided into five experimental groups: normal diet group, high fatᆞhigh cholesterol diet group, high fatᆞhigh cholesterol diet with 5% red pepper seeds powder supplemented group (SA group), high fatᆞhigh cholesterol diet with 10% red p...

mold powders used in the continuous casting of steel contain the harmful caf2 as a main substance developing toxic gases such as sif4 and hf at elevated temperatures. in this study, three samples of i1, i2 and i3, which contained gypsum free portland cement clinker with different percentages of fe2o3 (5.68, 6.83, 8.02 ) and f- (2.09, 1.06, 0), were prepared and their main characteristics were c...

Thermochemcial characteristics of powder fabricated using oxidation treatment of spent PWR fuel and SIMFUEL were evaluated for recycling of spent fuel such as DUPIC process. Especially, the influence of spent fuel burn-ups on the powder fabrication characteristics was experimentally evaluated, ranging from 27,300 to 65,000 MWd/tU. Densities of powder manufactured from an oxidation, OREOX and th...
