  • Roll along resistivity survey

    A roll-along survey is a method for operator to survey a long line. After the initial survey, the operator will leave one cable on the ground and move the instrument and cables forward. So there is always one cable overlap between two surveys. Alternatively, the operator can divide the cable in half and only overlap 16 electrode spacing. In this way, the opearator could complete the survey ...

  • Multidrug resistance in fungi

    One of the major advances serving to define the beginning of the era of modern medicine was the development of penicillin in the early 1940s as the first widely used antibiotic effective against microorganisms (reviewed in reference 111). In what has become an all-too-common trend, antibiotic-resistant isolates emerged soon after the large-scale use of penicillin to treat bacterial infections ...

  • The fundamental conductivity and resistivity of water

    Pure water has a very low. but not quite zero, electrical conductivity. This conductivity provides a probe into fundamental properties of water, including the electrochemical mobility of the hydrogen and hydroxide ions. Deviation from this value is a measure of trace ionic impurities. Ultrapure water (UPW). with impurities at or below the sub-parts-per-billion range, is used extensively in many ...

  • 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 [1]. Today, non-aqueous membrane filtration applications in chemical and pharmaceutical processing account for more than 25% of the global total polymeric membrane market [2]. ...

  • Flame Resistant Clothing

    Flame resistant (FR) clothing is designed as a means or protection against potentially fatal flash fire and arc flash environments.  The main source of fatal and serious burn injuries are usually due to the igniting of an individual’s clothing.  Flame resistant clothing allows precious time for the person wearing the clothes and also helps to prevent clothing ignition.  Keep in ...

  • HDPE - A Hydrocarbon Resistant Membrane?

    Most brownfield redevelopment and environmental protection applications require the use of a hydrocarbon resistant membrane.  However, each membrane material will vary in its ability to resist chemical attack and its effectiveness as a barrier to permeation.  It is essential that a barrier material prevents the migration of contaminants, thereby not harming the surrounding environment ...

  • Resistivity system voltage output

    One limit of FlashRES resistivity meter is its voltage output. It can output maximum voltage of 350v, this is because the multi-core cable of the FlashRES cannot withstand voltage over 350v. the multi-core cable contains 32 small wires, voltage higher than 350v will damage these wires and make the cable short circuit. We thus limit the maximum voltage output for safety reasons. Reference ...

  • Fiction EHC fluid resistivity

    Since the mid 1960's turbine hydraulic fluid systems have been using Fire Resistant Fluid (FRF) to control their turbine inlet valves. It is a known “FACT” that low fluid resistivity adversely affects the internal components of servo valves within the hydraulic fluid system. Root cause analysis studies conducted by numerous agencies have determined ...

  • Triclosan resistant bacteria in sewage effluent and cross-resistance to antibiotics

    The purpose of this study was to identify triclosan tolerant heterotrophic plate count (HPC) bacteria from sewage effluent and to determine cross-resistance to antibiotics. R2 agar supplemented with triclosan was utilised to isolate triclosan resistant bacteria and 16S rRNA gene sequencing was conducted to identify the isolates. Minimum inhibitory concentrations (MICs) of organisms were ...

  • 3D Resistivity survey case study

    The challenge with all 3D electrical resistivity surveys is that the sizable amount of information points needed. this can be to retain a high enough resolution despite the extra dimension. Conventional electrical resistivity meters with sub-units or switchers for 3D survey. The FlashRES electrical ...

  • What is 61-channel resistivity meter?

    FlashRES resistivity meter has 64 electrodes, it uses one common ground electrode, two electrodes as current injection electrodes. For each current injection between A and B, the FlashRES resistivity meter measures the potential on remaining electrodes against the common ground electrode. In this way, 61 MN voltages are measured and hence FlashRES is a 61 channal resistivity meter. ...

  • Identifying sources of resistance to change in healthcare

    The continuous introduction of new healthcare technologies, as well as the proliferation of new processes that guarantee better treatment and care of patients, suggests that the pace of the healthcare environment has been accelerating in recent years. Therefore, it is very important to identify and address sources of resistance to change before, during, and after change efforts are made in ...

  • Chlorine resistant membrane and the mechanism of membrane

    Polyamide reverse osmosis membrane used successfully for water desalination is made from the interfacial reaction of meta-phenylenediamine (MPD) with trimesoyl chloride. One problem with the membrane is that its performance is deteriorated upon prolonged exposure to chlorine often used for disinfecting feed water. ATR-FTIR and XPS analysis show chlorine reacts with the amide hydrogen and is ...

  • The water sector’s answer to antibiotic resistance

    Can you imagine a world in which antibiotics no longer work? Almost a century after Alexander Fleming’s discovery of penicillin in 1928, the era of life-saving, life-enhancing antibiotics may be coming to an end. Antibiotics, able to effectively treat bacterial infections in humans, animals and plants, have enabled some of the greatest advances in modern medicine. Now, however, the ...
