Most industrial facilities already know that contamination causes premature bearing failures. The harder problem is stopping it at the dispensing point — reliably, every time, regardless of who is doing the job. Walk through most manufacturing plants and you will find the same scene at lubrication time: a technician lifts the lid off an open drum, dips a hand pump, fills a can, and carries ...
The National Park Rapid Plume Assessment showcases the efficiency of LiORA Trends real-time modeling, utilizing 8 sensors to deliver critical insights in a fraction of the time. Get insights on your plume immediately rather than years or ...

In battery recycling, XRT distinguishes metallic from non-metallic particles regardless of surface condition, color, or coating, making it insensitive to contamination and oxidation that can confound optical sensors. XRT sorting is effective for separating electrode foils from separators and casings, and for detecting dense metallic contamination within bulk ...
The Groundwater Modeling Problem Nobody Talks About There are roughly 60,000 leaking underground storage tank (LUST) releases in the EPA's active remediation backlog, and over 1,343 active Superfund sites on the National Priorities List.(1,2) The average remediation timeline for both exceeds 10 years.(3) Most of these sites share one thing: either no numerical groundwater model at all, or a ...

Stainless steel electrodes (e.g., 316L) are commonly used to prevent contamination. Sanitary Design Choose a model that meets CIP (Clean-in-Place) and SIP (Sterilize-in-Place) requirements. ...
Whether you’re a business looking to offer more environmentally-friendly packaging—or a consumer looking for an alternative to plastic products—the green landscape can be a difficult one to navigate. Vague and misleading claims are common in this space—and these various forms of “greenwashing” make it incredibly difficult to identify optimal product ...
Keeping pH measurements operational in pulp and paper processes can be a time-consuming challenge. For a multinational company, changing to a METTLER TOLEDO solution for wastewater monitoring has dramatically cut their maintenance time and costs. ...
Here we directly compared the susceptibility of ePTFE grafts and HAV to bacterial contamination in a preclinical model of infection Materials and methods: Sections (1 cm2 ) of ePTFE (n ¼ 42) or HAV (n ¼ 42) were inserted within bilateral subcutaneous pockets on the dorsum of rats and inoculated with Staphylococcus aureus (107 CFU/0.25 mL) or ...
One of the great benefits of RockWorks is the quick volume calculations available through the RockPlot3D viewer. As the user adjusts the isosurface or filter settings (for example, to isolate material above a contamination threshold), the program returns a volume in cubic meters or cubic feet, depending on the project units. Let’s say that you then want to calculate the mass of ...
Objective The objective of this study was to evaluate the efficacy of Feed Energy-R2 nutrients at reducing the risk of infection following consumption of feed contaminated with PRRSV, PEDV and SVA using a novel, highly robust challenge model, employing controlled field conditions and multiple metrics. ...
The assessment levels provide the foundation for risk assessment process, which entails the creation of a conceptual site model to identify potential contaminants, comparison with assessment levels, and evaluation of possible risks. ...
Similarly, it is often required in order to obtain planning permission and develop the site. Contaminated land projects for planning usually require an initial ground evaluation, followed by a human health risk assessment using an appropriate model e.g. ...
At the graduate level, I teach courses in water treatment, water chemistry and surface water quality modeling. My research focuses on water quality and the safety of drinking waters. I study water from source to tap: where do contaminants originate, what is their fate in the environment, how do we engineer treatment processes to protect public health? ...
The Regional Screening Levels (RSL) can be described as risk-based concentrations derived from standardized equations combining exposure information assumptions with EPA toxicity data (United States Environmental Protection Agency, 2020). Why are SLs used? The EPA Regional Screening Levels (RSL) are used for site screening and as initial cleanup goals. In site screening, the most crucial role ...
” Our latest update: For projects where the site investigation is further along and there are already multiple monitoring wells and groundwater samples EnviMetric can use this information to make more precise predictions of contaminant extent and it does this differently than traditional fate and transport modeling. Traditional fate and transport ...

Abstract : Ten bioassays were used for the evaluation of acute, (sub)chronic toxicity and genotoxicity of an unknown soil from a military base and six model soils that were contaminated at former military bases with the major pollutants : kerosene, petroleum and used motor oil. ...
STS have been working on the next evolution of our ionising radiation contamination simulators! Our customers love the basis of our simulation technology which allows artificial contamination to be applied to a surface, spread, transferred and cleaned up -all whilst being monitored with a simulated meter and probe behaving as you would expect surface radioactive contamination to behave. Our ...
Similarly, it is often required in order to obtain planning permission and develop the site. Contaminated land projects for planning usually require an initial ground evaluation, followed by a human health risk assessment using an appropriate model e.g. ...
The project, which was founded in 1991 to develop reliable information about water sources to support decisions on water quality management and policy at every governmental level, uses several different types of modeling and analysis tools to estimate nutrient fluxes, pesticide concentrations and even understand sources of contaminants. ...
