Recovery from the Flint Water Crisis has been hindered by uncertainty in both the water testing process and the causes of contamination. In this work, we develop an ensemble of predictive models to assess the risk of lead contamination in individual homes and neighborhoods. To train these models, we utilize a wide range of data sources, including voluntary residential water tests, historical re...
We report the MR imaging features of a pleomorphic adenoma of the nasal septum. To our knowledge, whereas the CT findings of pleomorphic adenomas of the nasal septum have been reported, the MR features of this rare entity have not been reported in the English-language literature.
Whole-rock major and trace element and O, Sr, Nd and Pb isotopic data are reported for 3.0–0.89 Ma lamproites from the Leucite Hills, Wyoming, USA. The two main groups of lamproites, madupitic lamproites and phlogopite lamproites, are geochemically distinct and cannot be related to one another by either fractional crystallization or crustal contamination. It seems likely that the geochemical di...
Background and aims: In Iran herbal water and dried herb are as traditional medicinal and are consumed widely. Therefore, microbial evaluation of these products in term of public health is important. The aim of the present study was to study the contamination of some dried medical plants and distillates in the groceries of Shahrekord city. Methods: In thi...
Digitalization is an umbrella term that refers to all the technologies needed to become fully datadriven. There’s no specific list of technologies under digitalization, but we usually include cloud, big data and analytics, IoT, intelligence, virtual reality, mixed reality, blockchain, drones, and more. Additionally, digitalization is fueling the further use of cloud computing as companies in al...
A bacterium capable of degrading herbicide, pendimethalin, was isolated from the contaminated soil by enrichment culture technique and identified as Bacillus circulans. The organism grew on pendimethalin (1 g/L) as the sole source of carbon and accumulated 6-aminopendimethalin and 3,4-dimethyl 2,6-dinitroaniline as metabolites in the culture medium. The cell-free extract of B. circulans grown o...
In a national study of births to farmers in Norway, grain farming was associated with short gestational age (21-24 weeks). An impact of selective fertility and maternal heterogeneity on the association was suspected but could not be assessed further in a traditional birth-based design. Thus, analyses based on the mother as the observational unit were performed. A total of 45,969 farmers with a ...
New regulatory and consumer demands highlight the importance of animal feed as a part of our national food safety system. Porcine epidemic diarrhea virus (PEDV) is the first viral pathogen confirmed to be widely transmissible in animal food. Because the potential for viral contamination in animal food is not well characterized, the objectives of this study were to 1) observe the magnitude of vi...
This paper summarizes parenteral drug contamination case studies presented at industry conferences and a Food and Drug Administration advisory committee meeting in the period of 2000-2004. CGMP deficiencies associated with each contamination event are discussed. The key role of a well-functioning quality system in contamination prevention is emphasized.
