Maximum Limit

This study was aimed to test the level of mesophilic aerobic bacteria contamination on chicken shank in "soto" food from restaurants in three different locations, Inong Balee-Darussalam, Ulee Kareng, and Campus of Unsyiah. A purpossive sampling method was used in this study. The sample of chicken shank in soto were collected in the morning at 10.00 a.m. and in the afternoon at 14.00 p.m. Samples were collected for 3 consecutive days. For each sampling, a total of 25 grams of chicken shank was put into plastic bag and directly transfer to the Veterinary Public Health Laboratory, Faculty of Veterinary Medicine of Syiah Kuala University. The result showed that the chicken shank in the soto food from three locations of restaurant had been contaminated with mesofilic aerobic bacteria with contamination level exceeds the maximum limit of microbial contamination as allowed in SNI - 2000.Key words: soto, shank, restaurants

AbstractNinety-six specimens of intravenous fluid solutions (D5/025 NS) were inoculated with S. aureus, E. coli, P. aeruginosa, K. pneumoniae, E. agglomerans, or C. albicans in concentrations of .1, 1, 10, or 102 organisms/ml. They were cultured in tubes containing 5 ml of double enriched broth and after passage through a .45 μ pore membrane filter. After 24 hours of incubation, broth cultures were 68% as sensitive as the filter cultures (p<.001). At the lowest concentration (.1 organism/ml) broth cultures were only 45% as sensitive as the membrane filter technique after 24 hours of growth (p<.001). Membrane filters provide a rapid method to accurately detect and quantitate the presence of microbial contamination even at very low levels of concentration. The simplicity and accuracy of the filtration method offers the clinician a valuable adjunct in managing suspected cases of intravenous fluid related sepsis.

New System

Power consumption and metering accuracy of reaction-injection-molding (RIM) fluid-delivery systems are examined. Emphasis is on the use of simple models to understand the source of metering errors and to estimate the magnitudes of these errors. Typical examples are given. The basic understanding provided by these models is used to explain the advantages of a new type of RIM fluid-delivery system developed at M.I.T. The new system offers reduced machine size and cost by minimizing instantaneous power requirements, and the metering system can achieve higher accuracy than conventional equipment while using less-accurate components.
