  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...

  • Exploring the link between handwashing proxy measures and child diarrhea in 25 countries in sub-Saharan Africa: a cross-sectional study

    Handwashing (HW) with soap is considered the most cost-effective intervention for reducing the risk of child diarrhea, but reliable measurement of HW behaviors is difficult. This study examined the association between proxy HW measures and child diarrhea by analyzing nationally representative household survey data from 25 countries in sub-Saharan Africa (n = 212,492). The main explanatory ...

  • How & Why We Measure Suspended Solids

    In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a wastewater or industrial system. Suspended Solids ...

  • Oxidative stress response of the aquatic macrophyte Hydrilla verticillata exposed to TiO2 nanoparticles

    The present study investigated the effects of titanium dioxide nanoparticles (TiO2‐NPs) on the oxidative stress response in Hydrilla verticillata. Macrophytes were exposed to different concentrations of TiO2‐NPs (0 mg/L, 0.01 mg/L, 0.1 mg/L, 1 mg/L, 10 mg/L) for 24 h, based on currently predicted levels of nano‐TiO2 in surface waters. Additionally, TiO2‐NPs with varying crystalline statuses ...

  • Materiality Assessment for Dummies

    When I started to work in the area of sustainability, I had no idea what a materiality assessment was, and what all the acronyms like GRI and SASB meant. It occurred to me I probably wasn’t the only one, and now that materiality assessment is such a hot topic, I thought it would benefit others to review. For this, I turned to our Corporate Sustainability Officer at PE International, ...
