  • Evaluation of the Gamma and Neutron Radiation Scattering and Transmission Methods for Soil Density and Moisture Determination

    In order to warrant the accuracy of soil density and moisture data from measurements by means of the gamma and neutron radiation attenuation methods several influencing factors have to be taken into account, for example, the soil hydrogen content, the soil inhomogeneity, the resolution characteristics of the measuring device and the probe travel velocity. Some interpretation concepts, related to ...

  • 5 Key elements to look for in your etch process

    High wafer throughput Fast etch rates and low clean overheads mean higher tool uptime. Higher uptime means more wafers through your fab Profile control Vertical facets means higher device efficiency – more light out for power in Smooth surfaces Smooth surfaces means less light scattering – more usable ...

  • Verification of wind energy related measurements with a SODAR system

    Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...

  • Mathematical modelling of flue-gas desulphurisation using lime slurry in a turbulent contact absorber

    A mathematical model has been developed for absorption of SO2 from flue gases using lime slurry in Turbulent Contact Absorbers (TCA). In this model, the TCA was simulated by considering it as a falling film absorption system. Turbulent effects were taken into account by using eddy viscosity and eddy diffusivity. The system of partial differential equations of mass transfer with moving boundaries ...

  • CAS DataLoggers Helps You Get Ready for RICE NESHAP

    Manufacturers across the country are scrambling to prepare for RICE NESHAP, an incoming EPA regulation intended to reduce pollutants from several categories of new, existing and reconstructed stationary engines. The focus is on air toxics, and all applicable diesel and non-diesel engines must be retrofitted with an emission control product to meet the new requirements by 2013. Every diesel ...
