A metagenomic library of activated sludge was screened for bleomycin resistance genes. Two genes were identified that differed greatly from each other, from the genes of bleomycin-producing actinomycetes, and from those of clinical isolates. Therefore, the nonclinical environment is a rich reservoir of new resistance elements, and metagenomics can be used to sample the resistome rapidly.

Using Resistivity for Basalt Site Characterization - Case Study
Purpose A mining company in Turkey hoped to determine existing and new alternative basalt zones at an existing basalt mining site by using Electrical Resistivity Imaging (ERI). Process Our client,Ali Karan, used 84 electrodes spaced at 10 meters and two lines 5 meters apart inside the study area. The dipole-gradient array was used to collect the 2D electrical resistivity imaging data set. Results Resistivity imaging mapped the vertical and lateral limits of basalt zones successfully. The ground truth was...
2D Resistivity Imaging for Locating Concrete Pipe - Case Study
Background There are 8 wells thatsuply water to the communnity through about 2m diamter concrete aqueduct. Purpose The main subject of the field tes was to determine the geotechnical site characterization of the area to correlate the results obtained through the 2D resistivity imaging and the infromation of the concrete aqueduct. Process The determination of site characterization was performed by AGI SuperSting Wi-Fi R8/IP/SP instrument with 42 electrodes and 3 meters electrode spacing with a mixed array of...
A history of chemically resistant membranes
The use of polymeric membranes for filtration of non-aqueous solutions started around 1960 and has been developed significantly since then . Today, non-aqueous membrane filtration applications in chemical and pharmaceutical processing account for more than 25% of the global total polymeric membrane market .To put into perspective the potential significance of membrane filtration for non-aqueous solutions, one must realize that conventional separation processes still accounts for up to 70% of capital (CAPEX)...
Towards a research agenda for water, sanitation and antimicrobial resistance
Clinically relevant antimicrobial resistant bacteria, genetic resistance elements, and antibiotic residues (so-called AMR) from human and animal waste are abundantly present in environmental samples. This presence could lead to human exposure to AMR. In 2015, the World Health Organization (WHO) developed a Global Action Plan for Antimicrobial Resistance with one of its strategic objectives being to strengthen knowledge through surveillance and research. With respect to a strategic research agenda on water,...
Advantages of Corrosion Resistant Lighting in Offshore Helidecks
Advantages of Corrosion Resistant Lighting in Offshore Helidecks Corrosion resistant lighting must be installed in offshore helidecks due to the extreme nature of the hazardous location. The use of such luminaries can extend the lifespan of the location’s lighting system and provide safety for aircraft pilots and workers on the site. Read on to understand the benefits of corrosion resistant lighting, and specific requirements for offshore helideck fixtures. Corrosion Resistant Lighting Properties E...
