Salmonella sp. and Escherichia coli became contaminator bacteria that influenced the microbiological quality of beef. Environmental conditions, facilities, slaughterhouse infrastructure cause contamination. This study aimed to determine presence contamination on slaughtered beef from Binjai City Tavip Market. used a descriptive purposive sampling technique 12 samples (6 six Market). was conduct...

This article is the second of a three-part series that investigates the application of the ventilation equations to designing and testing cleanrooms. This part is concerned with the decay equation. The recovery test, described in ISO 14644-3 (2005) is discussed, and improvements recommended. The application of the decay equation to the ‘clean up’ requirement given in the EU GGMP (2008) is also ...

The flow of transgenes into landraces and wild relatives is an important biosafety concern. The case of transgene flow into local maize varieties in Mexico (the center of origin of maize) has been intensively debated over the past 15 years, including legal, political, and environmental disputes fanned by the existence of a significant scientific controversy over the methods used for the detecti...

Introduction: Photon contamination is a restriction on treatment with electron that increase dose to healthy tissue below the tumor. The aim of this study is to reduce the photon contamination using a magnet system. Materials and Methods: A mini-applicator equipped with two neodymium boron permanent magnets was designed which make it possible to adjust the d...

This preparation would maintain good contrast and reduce the formation of lead carbonate in resin-embedded tissue sections. new method provides a shorter staining protocol fewer than 5 minutes, extended storage duration, improved contrast, higher broad differential range, prevents contamination from environment. Introducing 20% ethanol to citrate formula makes it be more stable nitrate formula.
