KG have closed the circle on their raw material cycle by utilising a briquetting press from RUF: cast chips produced during the machining of parts for water supply and sewage disposal are pressed to solid briquettes and then melted in the in-house foundry and ...

  • Integrating toxicity reduction strategies for materials and components into product design: A case study on utility meters

    Using RIO Tronics utility meter products as an industrial case study, the numeric Fraunhofer Toxic Potential Indicator (TPI) assessment tool is employed to determine high impact materials with the aim of reducing the content of inherently toxic substances in these products. However, because product re‐design with alternative materials affects entire components, overall component toxicity ...

  • New Developments in Thermal Dispersion Mass Flow Meters: In-The-Field Compensation for Changes in Natural Gas Composition

    Introduction The flow of natural gas in pipelines is often complicated by changes in the composition of the gas. The method described in this paper solves the problem of variable composition via a new four-temperature mass flow sensor. The new (low sensor feeds its measurements into the algorithms of an advanced mathematical model that includes gas properties in its calculations. The method ...

  • REDmeters - Blue Paper

    REDmeters: Abstract The process of controlling and the cost of monitoring slurries in many industries are normally accomplished using various continuous mass flow systems. These types of systems usually contain a magnetic flow meter and a line density meter. There is inherent cost associated to these systems due to the inaccurate nature of these meters. Some meters on the market boast up to ...

  • Measurement of glucose nanoparticles concentration in plasma and blood accurately using laser sheet interferometry

    Diabetes is one of the major diseases in Egypt and perhaps all over the world. Diabetic patients suffer from many acute and chronic symptoms and diseases which may lead to blindness, reduced blood circulation in extremities arising ulcers and gangrenes. In this paper, we present a new technique called the laser sheet interference technique developed by the first author, for measuring the optical ...

  • Modeling of radial well lateral screens using 1D finite elements

    A water supply system including radial wells (RWs) is usually large, extending several tens of kilometers horizontally and is dozens of meters deep. An RW is a vertical shaft with lateral screens, which radially penetrate the soil. A large and complex 3D finite element (FE) mesh also needs to include laterals with cross-sectional dimensions measured in centimeters. An adequate representation of ...

  • Effect of sodium azide on the metabolic activity of cultured fetal cells

    Sodium azide is a highly toxic substance. However, the mechanism of its toxicity has not been fully established. In the present study, we attempted to investigate the toxicity of sodium azide in various cultured fetal cells, using changes in cellular respiration as an indicator of metabolic inhibition to elucidate tissue-specificity. The human fetal cell lines used in this study included ...

  • Dewatering Crews Keep the Alameda Corridor Dry and Open for Business

    Griffin installed a multitude of deep wells along the alignment of the proposed railway to allow for construction. The discharge from the wells was pumped via large diameter high density polyethylene pipe (HDPE) to a below grade mixing vault, where a neutralizing agent was introduced to the groundwater as the quality of the groundwater was not allowed to discharge to the designated receiving ...

  • Influence of earthworm Eisenia fetida on Iris pseudacorus's photosynthetic characteristics, evapotranspiration losses and purifying capacity in constructed wetland systems

    Four constructed wetland systems were studied to investigate the effects of adding Eisenia fetida on the purifying capacity of constructed wetlands. Addition of E. fetida increased the photosynthetic rate (Pn), transpiration rate (Tr) and chlorophyll meter value of leaves of Iris pseudacorus L. in the ...

  • A simple numerical method for snowmelt simulation based on the equation of heat energy

    This paper presents one-dimensional numerical model for snowmelt/accumulation simulations, based on the equation of heat energy. It is assumed that the snow column is homogeneous at the current time step; however, its characteristics such as snow density and thermal conductivity are treated as functions of time. The equation of heat energy for snow column is solved using the implicit finite ...

  • Hulless barley seeding rate effects on grain yield and yield components

    Recent efforts to expand markets for winter barley (Hordeum vulgare L.) in the mid-Atlantic have focused on hulless types due to higher energy density. The exposed endosperm of hulless barley makes damage more likely than with hulled barley, and emergence is typically lower. Information to determine the optimum seeding rate for winter hulless barley is presently unavailable. Experiments were ...

  • Does Wind Turbine Blade Length Really Matter?

    Simply put: Longer wind turbine blade length means greater power production. Blades capture the wind which forces the rotation of the rotor; longer blades means more area for the wind to push against, which means greater force and rotational power. However, how much difference does blade length make overall, in comparison to other factors? There is a standard formula that can be used to apply the ...
