Bacteriocin producing Lactobacillus acidophilus and Pediococcus acidilactici were isolated from milk and meat samples, respectively. An attempt was made to produce bacteriocin in a Dairy Based (DB) medium using these organisms. Higher bacteriocin activity was shown by L. acidophilus in the DB medium. Bacteriocins of both the organisms were effective against food pathogens. The bacteriocins were...

20a-Hydroxy-A4-pregnen-3-one-20p-3H can be detected after incubation of progesterone and estradiol-17a-3H with slices of female rat liver and rat ovaries, which proves the transfer of hydrogen from estradiol to progesterone. While 20oc-hydroxy-A4-pregnen-3-one is found only in very small amounts after incubation of progesterone with female rat liver slices the reduction at CzO increases 20-fold...

This paper describes the design of a bandgap reference, implemented in 0.50 μm CMOS technology. The circuit generates a reference voltage of 1.2218V. It can operate between 20oC & 70o C. Total variation of reference voltage within the temperature range is 2.6mV which is 0.213% of the reference voltage. This circuit works in a current feedback mode, and it generates its own reference current, re...

Copper shows promising characteristics for applications in electrical sliding contacts. In this study, copper reinforced polylactic acid (PLA-copper) composites manufactured by fused deposition modeling (FDM). Wear behaviour of PLA-copper under dry conditions at three different temperature (20oC, 50oC, 70oC) was evaluated using pin-on-disc wear test equipment with attached heating module 5N loa...

The difference in temperature between the of basin water and glass cover is most important regulating factor for getting yield from a solar still. higher differential, more distillate still produces. This can be enhanced either by increasing decreasing or combining both strategies together. A strategy lowering to cool it with air flowing water. Cooling not only boosts production but also cleans...

AritraChatterjee The cholesterol oxidase enzyme breaks down cholesterol into an intermediate cholest-5-en-3-one, which is then converted to cholest-4-en-3one (Smith and Brooks 1997) . In the present study this mechanism was exploited. The current produced by the release of electrons from the above reaction was used to determine the amount of free cholesterol in the serum sample. The functioning...

Recent work suggests an influence of the mean body skin (Tsk) and deep body temperatures (Tb) on coldinduced vasodilatation (CIVD). For example, minimum finger temperature (Tfi,min)was lower, and the maximum finger temperature (Tfi,max) was greater during CIVD when Tb was elevated, and the onset time of the CIVD response was reduced at higher Tsk. Question remain, though, about the influence of...

Total protein describes the liver's ability to synthesize proteins and metabolize substances in blood. Bovine serum can be used as a control material because total analyte bovine blood is almost identical human serum. The researchers intend determine homogeneity stability of with addition 7,5% ethylene glycol preservative after being stored for 12 weeks at -20°C an alternative levels. This rese...

Dehydrofreezing is a food freezing method in which the foods are partially dehydrated before freezing. In this study, carrots were frozen with convective (-30, -35, -40oC and 2 m/s airflow) cryogenic methods after dehydrating them by different (osmotic dehydration, vacuum drying). The effects of dehydration method, conditions storage time on β-carotene amounts dehydrofrozen changes content duri...
