  • How to choose detectors in the dangerous cargo warehouse

    The principle of choosing toxic gas and combustible gas detectors in dangerous cargo warehouse: 1.Dangerous cargo warehouse detection of gas mainly including combustible or toxic. Measurement of the type of gas characteristics, the first is to measure the explosion, second is the measurement of toxicity. The so-called measuring explosion is the detection of combustible gases, such as ...

  • Nitrogen Refrigerated Trucks a New Trend? An Alternative to Diesel Powered Refrigeration

    Nitrogen Refrigerated Trucks a New Trend? An Alternative to Diesel Powered Refrigeration Thanks to technological innovations, the food distribution industry has a greener way to protect refrigerated food during transit: Nitrogen refrigeration. The existing system relies on diesel-powdered mechanical refrigeration units.

  • Confined spaces are dangerous places

    Our safety focus in February is on working safely in confined spaces. Confined spaces present some unique and serious hazards that can result in severe injuries and even death. Each year, hundreds of workers die from accidents in confined spaces.  Confined space entry incidents are the leading cause of occupational fatalities in the U.S., primarily as a result of workers ...

  • Array gain and reduction of self-noise

    Abstract—Because an array is composed of many sensors, each making an independent measurement of the wavefield, intelligent combination of the sensor signals should lead to an overall increase in the signal-to-noise ratio. What we are trying to achieve is enhancing the signal with an array beyond what is possible with a single sensor. The array gain measures an array’s signal-to-noise ...

  • Keeping Healthcare/SPD Workers Safe from Exposure: 2 Very Different Options

    Continuous Monitoring vs. Badges Badges are designed to provide the Time Weighted Average (TWA) data for the total exposure period. They contain an absorption medium that reacts with or absorbs and holds the target chemical from the air to be analyzed later, which indicates the exposure after the fact. Badges, sample tubes, and wet chemical methods were the predominant technologies for monitoring ...

  • Synthesis and performance of antifouling and self-cleaning polyethersulfone/graphene oxide composite membrane functionalized with photoactive semiconductor catalyst

    This study was performed to synthesize membranes of polyethersulfone (PES) blended with graphene oxide (GO) and PES blended with GO functionalized with photoactive semiconductor catalyst (TiO2 and ZnO). The antifouling and self-cleaning properties of composite membranes were also investigated. The GO was prepared from natural graphite powder by oxidation method at low temperature. TiO2 ...

  • Prediction of scour depth around bridge piers using self-adaptive extreme learning machine

    Accurate prediction of pier scour can lead to economic design of bridge piers and prevent catastrophic incidents. This paper presents the application of self-adaptive evolutionary extreme learning machine (SAELM) to develop a new model for the prediction of local scour around bridge piers using 476 field pier scour measurements with four shapes of piers: sharp, round, cylindrical, and square. ...

  • Self-purification of marine environments for heavy metals: a study on removal of lead(II) and copper(II) by cuttlebone

    The aim of this study was to determine adsorption properties of cuttlebone, cuttlefish bone as dead biomass, for lead(II) and copper(II) from aqueous solutions. Adsorption kinetic, isotherm and effect of pH (in the range of 2.0–7.0) were investigated in a single component batch system at room temperature (25 ± 1 °C). The heavy metal adsorption by cuttlebone was relatively rapid ...

  • Carbon Monoxide (CO) and Carbon Dioxide (CO2) Safety

    Know the Gases, Know the Dangers and Protect Yourself Do you know the differences between carbon monoxide (CO) and carbon dioxide (CO2)? If you don’t then there are no guarantees your safety measures will be adequate. These two different gases are often mixed up with people becoming confused over which they need to protect against, when and how. ...

  • Alberta Sees an Alarming Rise in Suicide Rates Following Harsh Oilpatch Layoffs

    Following rising rates of layoffs in Alberta’s oil and gas industry in response to low oil prices, suicide rates in that province have increased by an alarming 30 percent this year. There were 327 suicides recorded between January and June 2015 and it is predicted that number could swell to 654 cases by year’s end. According to the Centre for Suicide Prevention, Alberta sees ...

  • Self-adjustment mechanism of bed structures under hydrology and sediment regimes

    Bed structures develop in many coarse gravel-bed rivers, and the distribution of bed structures is obviously impacted by the environment conditions, especially hydrology and sediment regimes. This study carried out field investigations in natural tributaries of the Yangtze River to study the sizes of bed structures, their distribution in the basin, as well as their connections with local ...

  • Classification of groundwater chemistry in Shimabara, using self-organizing maps

    Shimabara City in Nagasaki Prefecture, Japan, is located on a volcanic peninsula that has abundant groundwater. Almost all public water supplies use groundwater in this region. For this reason, understanding groundwater characteristics is a pre-requisite for proper water supply management. Thus, we investigated the groundwater chemistry characteristics in Shimabara by use of self-organizing ...

  • PureAire Universal Gas Detector Offers Protection Against Toxic Levels of Ammonia

    In March of 2016, an ammonia gas leak at a seafood processing plant in Boston left one worker dead. The fumes at the plant were so powerful that firefighters could not promptly enter the scene to mitigate the gas leak and try to save the staff member until much later. Reports show that 5,300 pounds of ammonia gas leaked out of the plant. If you work with ammonia at your facility, learn ...

  • Hydropolitical Self-Organization theory; system dynamics to analyse hydropolitics of Helmand transboundary river

    The paper is based on the hydropolitical driver concept and analyses non-technological drivers responsible for the depletion of water resources determining the hydropolitical situation over time. To tackle the complexity stemming from the heterogeneity of drivers, the paper adopts both theoretical hydropolitics (hydropolitical driver concept) and system dynamics (SD) (causal loop diagrams ...
