  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Proliferation resistance and the nuclear renaissance

    Currently, nuclear power provides 16% of the world's electricity, using 439 reactors in 30 states and in Taiwan, China. This paper explores how emphasising proliferation resistance can guide decisions allowing increasing use of nuclear power without challenging international security. It reviews the definition of proliferation resistance and describes how proliferation resistance for a given fuel ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • Ceramic membranes with higher abrasion resistance

    High flux rates, combined with a very high chemical and thermal resistance and the resulting operational reliability - these are the reasons why users worldwide opt for ceramic membranes. Up to now, the only parameter where ceramic membranes performed well but not excellent was abrasion resistance. Therefore, filtering of abrasive matter required pre-treatment stages such as prefiltration, ...
