Therefore, pellet samples were collected with care to avoid contamination from the exterior of the bags.
The challenge of maintaining infection control in an improvised ICU includes control of environmental contamination from the exterior as well as the risk of cross-contamination between patients in crowded conditions and when basic supplies are limited.
In 2012, Barack Obama signed legislation directing the DoE to monitor the groundwater beneath the dome, conduct a visual study of its exterior and submit reports determining whether contamination in the dome poses a health risk to the dri-Enewetak.
Methodologies for estimation of doses received through nine different pathways, including contamination of streets, roofs, exterior walls, and landscape, are established, and best estimates are given for each of the dose contributions.
Microspheres dispersed during drilling operations to constrain drilling induced contamination were observed on the exterior, but not in the interior of all core samples.
These results were interpreted to mean that the exterior of the feedbags had become contaminated with PEDV in the barn during the outbreak; however, since PEDV was detected in the interior of the unopened bags of the new supplier's pellets, PEDV contamination of this feed had to occur prior to delivery at the barn.
The system throughput was limited to a single chip per hybridization unit and the handling and purification was difficult due to small exterior buffer reservoirs and small buffer tubes, leading to contamination concerns.
In closed wounds, by contrast, the damaged tissues are not exposed to the exterior, and the process of repair can take place without the interference that contamination always brings, in greater or lesser degree.
However, post-harvest handling like the milking personnel and milk handling containers might generally be source of microbial contamination for raw milk, the three main sources of bacterial contamination; within the udder, exterior to the udder from the surface of teats, milk handling and storage equipments (Abate et al. 2015: Reta et al. 2016).
