During the previous survey year (Year 2), a methodological issue arose which meant that our measures were no longer providing a reliable indication of how levels of contamination in chickens at retail were changing over time, or providing like for like comparisons between retailers. This methodological issue is explained in the January-March 16 report: www.food.gov.uk/sites/default/files/campy-...

Despite their potential use as pixel-switching elements in displays, the bias and light instability of mixed oxide semiconductor thin-film transistors (TFTs) still limit their application to commercial products. Lack of reproducible results due to the sensitivity of the mixed oxides to air exposure and chemical contamination during or after fabrication hinders any progress towards the achieveme...

background: iran is located within the dry and semi dry regions, thus almost 90% of the required water is secured via the use of groundwater. owing to the increasing pollution of water resources, this study was performed to evaluate water quality pollution indices for heavy metals (as, zn, pb and cu) contamination monitoring in toyserkan plain during spring and summer in 2012. methods: a total ...

Trimming procedures are an important part of the sequence analysis pipeline in an EST Sequencing Project. In general, trimming is done in several phases, each one detecting and removing some kind of undesirable artifact, such as low quality sequence, vectors or adapters sequence, and contamination. However, this strategy often results in a phase being unable to recognize its target because part...

It is well known that the bioavailability of artifical radionuclides such as Sr, Cs and Pu in contaminated soils depends on the source term origin of the contamination. Altough the behaviour of the mentioned radionuclides in the soil is also influenced by the time passed from the contamination event and the characteristics of the contamination receiving soils. The objective of the present work ...

In 1987, the curriculum of Environmental Sciences was introduced at Swiss Federal Institute of Technology Zurich ([Eidgenössische Technische Hochschule Zurich], ETHZ). The curriculum was motivated by demands and pressures that characterize our post-industrial age, particularly the necessity to understand complex environmental problems and assess their long term impacts from an interdisciplinary...

A 69-day experimental study was conducted to investigate the treatment process of municipal wastewater using submerged membrane bioreactor technology. The results show that the average removal rate of COD and BOD5 were over 90%. The removal rate of NH3-N was 99% and the concentration of effluent NH3-N was below 0.5mg/L; because of the high DO value in the denitration sect, the denitrobacteria w...

We inventoried non-surface water sources in the Leogane and Gressier region of Haiti (approximately 270 km(2)) in 2012 and 2013 and screened water from 345 sites for fecal coliforms and Vibrio cholerae. An international organization/non-governmental organization responsible for construction could be identified for only 56% of water points evaluated. Sixteen percent of water points were non-func...
