Direct detection of Mycobacterium avium in environmental water and scale samples by loop-mediated isothermal amplification

by IWA Publishing  (Jun. 18, 2014)

We previously demonstrated the colonization of Mycobacterium avium complex in bathrooms by the conventional culture method. In the present study, we aimed to directly detect M. avium organisms in the environment using loop-mediated isothermal amplification (LAMP), and to demonstrate the efficacy of LAMP by comparing the results with those ...

by Gasmet Technologies Oy  (May 13, 2014)

Antti Heikkilä from Gasmet Technologies highlights the challenges faced by mercury monitoring in cement kilns, and explains how a new continuous mercury monitoring system addresses these issues and provides process operators with an opportunity to improve environmental performance and demonstrate compliance with forthcoming legislation. ...

Biofuel - Energy Supplier of the Future?

by Fritsch GmbH - Milling and Sizing  (May 16, 2014)

Biofuel like biodiesel, plant oil, ethanol, bio methane or the synthetic biomass- to- liquid (BtL)- fuels everyone is talking about them. They are at present the only renewable alternative in the mobility sector and already today make up 6.1 % of the fuel consumption in Germany. However, in the past months and years biofuels had the reputation ...

C6-C10 Gasoline range Hydrocarbons in Soil case study

by Sitelab Corporation  (May 1, 2014)

These case studies illustrate the performance using Sitelab’s UVF-3100 analyzer testing gasoline range organic (GRO) hydrocarbons, also called volatile petroleum hydrocarbons (VPH). The analyzer has optical filters sensitive and selective to hydrocarbons in the C6-C10 carbon range, including benzene, xylene and other BTEX compounds abundant ...

Environmental impact of irrigation with greywater treated by recirculating vertical flow constructed wetlands in two climatic regions

by IWA Publishing  (Jun. 25, 2014)

Reuse of greywater (GW) has raised environmental and public health concerns. Specifically, these concerns relate to onsite treatment operated by non-professionals; systems must therefore be reliable, simple to use and also economically feasible if they are to be widely used. The aims of this study were to: (a) investigate GW treatment efficiency ...

A license to operate? An empirical examination of the influence of environmental and social performance on the financial performance of mining sector firms

by Inderscience Publishers  (Jun. 25, 2014)

The notion that firms owe a duty to the wider communities in which they operate is now widely accepted among practitioners and academics. If there is a link between corporate environmental and social responsibility (CESP) and corporate financial performance (CFP), no sector is likely to be more sensitive than the mining sector. I investigate the ...

Predicting the occurrence of stoneflies (Plecoptera) on the basis of water characteristics, river morphology and land use

by IWA Publishing  (Jul. 16, 2014)

Stoneflies are macro-invertebrates that are sensitive water quality indicators. Here, their occurrence was modelled based on physical–chemical water characteristics, river morphology and land use with five different modelling techniques. In a case-study in Flanders, stoneflies were found in 219 samples and two sets of absence data were ...

Improved derivatization protocol for simultaneous determination of alkylphenol ethoxylates and brominated flame retardants followed by gas chromatography-mass spectrometry analyses

by IWA Publishing  (Jun. 25, 2014)

An improved derivatization protocol for the simultaneous determination of alkylphenol ethoxylates and brominated flame retardants with heptafluorobutyric anhydride under triethylamine amine base was investigated. The derivatization reaction was completed in 30 min at 50 °C using hexane as solvent. Under these conditions, it was observed ...
