Abstract:

Surface contaminations can critically affect the performance of optical surfaces, in particular with respect to light scattering, optical losses, and laser stability. Thus, avoiding contaminations and reducing contamination-induced effects is of particular interest in the manufacturing of optical systems. By combining a specific thin film design with a tailored structural design, contamination-resistant coatings with a high optical quality can be realized. Most important is the balance of self-cleaningand light scattering-relevant surface roughness components.

Abstract:

AbstractAccelerator mass spectrometry (AMS) measurements of the radiocarbon content in very old samples are often challenging and carry large relative uncertainties due to possible contaminations acquired during the preparation and storage steps. In case of such old samples, the natural surrounding levels of 14C from gases in the atmosphere, which may well be the source of contamination among others, are 2–3 orders of magnitude higher than the samples themselves. Hence, serious efforts are taken during the preparation steps to have the samples pristine until measurements are performed. As samp

<em>Food is regarded as hygienic and safe for consumption when it does not pose any threat or risk to the health and economy such as sales loss. Food contamination occurs when bacteria or other germs get into food, which can cause food-borne illness. While most food contaminations are accidental, there has been some evidence of intentional food contamination.  A major accident in food contamination can cost a company a massive recall that may be devastating to its reputation and profit because it has serious consequences for the health and wellbeing of people and the planet.

Salmonella Senftenberg was isolated in 573 (16.8%) samples, and no other serovar was detected. The contamination episodes extended for several months. Salmonella Senftenberg colonies from the first contamination events showed a rugose morphology on agar with a shiny crystalline layer and limited colony form

Abstract:

This paper describes commonly used processes to produce aviation fuel and alternative routes with potential production yields for sustainable aviation fuels (SAF) like HEFA and ATJ. It also presents the possible sources (crude oil, refinery processes), causes (filter clogging, engine failure), and forms of contamination in both conventional and alternatively produced aviation fuels. Special attention is focused on the threats of fuel contamination with solid particles/trace elements, water, microorganisms, and fatty acid methyl esters (FAME). This review also presents the standard and novel ad

Abstract:

One of the significant issues that the world has faced in recent decades has been the estimation of water quality and location where safe drinking water is available. Due to the unexpected nature of the mode of water contamination, it is not easy to analyze the quality and maintain it. Some machine-learning techniques are used for predicting contaminating factors but there is no technique that can predict the contamination using latitude, longitude, and elevation. The main aim of this paper is to put factors such as water body location and elevation, which are used as inputs, into the differen

Ready-to-eat (RTE) deli meats are considered a food at high risk for causing foodborne illness. Deli meats are listed as the highest risk RTE food vehicle for Listeria monocytogenes. Cross-contamination in the retail deli market may contribute to spread of pathogens to deli meats. Understanding potential cross-contamination pathways is essential for reducing the risk of contaminating various products. The objective of this study was to track cross-contamination pathways through a mock retail deli market using an abiotic surrogate, GloGerm, to visually represent how pathogens may spread through

The article identifies the effects of human activity on groundwater chemistry in the regional aquifer system located in the Wielkopolska region (western Poland). It was documented using statistical methods, that the main process influencing the groundwater chemistry is connected to contamination. The impact of contamination is evident in regions without sewers and where the aquitard is relative thin. Chloride and sulphatewere found most influenced by pollution from surface sources. Total hardness is also sensitive, but its behavior is controlled by geogenic processes as well. Factor analyses a

Worldwide, one of the biggest concerns for water quality is the contamination of water resources by water-borne pathogens and the diseases that result from it. An increasing number of recent publications attest to the need for studies that synthesize knowledge from multiple fields, covering comparative aspects of pathogen contamination and unify them in one place in order to present and address the problem as a whole. These publications also demonstrate the growing interest in controlling water-borne pathogens in water resources. Contamination arises from pathogens (bacteria, viruses, parasite

Furthermore, there were several studies of microorganism contamination in the air and surface at human operating theatre. However, studies in veterinary operating theatre related to the effectiveness of UV light on sterilization process is still limited, especially in Indonesia.

Abstract:

Whole-genome sequencing (WGS) of bacterial pathogens is currently widely used to support public-health investigations. The ability to assess WGS data quality is critical to underpin the reliability of downstream analyses. Sequence contamination is a quality issue that could potentially impact WGS-based findings; however, existing tools do not readily identify contamination from closely-related organisms. To address this gap, we have developed a computational pipeline, ConFindr, for detection of intraspecies contamination. ConFindr determines the presence of contaminating sequences based on the

Abstract:

Bacterial DNA contamination of rust fungal DNA can be a significant problem for sequencing the rust fungus. Sequence assembly is much more difficult if the sequence contigs are mixed with bacterial sequence. A quantitative real-time polymerase chain reaction (qPCR) assay was developed to quantify bacterial DNA within rust fungal DNA samples and the results were compared with those obtained from traditional CFU counts. Real-time PCR showed higher values of DNA contamination than CFU. However, the ranking of samples from low to high for bacterial contamination was consistent between the methods.

In environmental research, it is often the case that to cluster observations into environmentally polluted and natural groups is an important issue. The Bayesian contamination model which adopts a multivariate mixture regression model has been developed in that it aims to cluster observations and estimate the average amount of pollution. However, because the Bayesian contamination model does not take spatial correlations between observations into consideration, a Bayesian spatial contamination model is proposed. A simulation study was conducted showing that the proposed model has an advantage

There is sufficient evidence to show that mining and related activities were responsible for contaminating soil, water and vegetation. Smelting of ore caused higher degree of contamination.
