  • Evaluation of overland flow model for a hillslope using laboratory flume data

    Comprehensive modelling of overland flow requires models for both rill and interrill area overland flow. Evaluation of a physically based mathematical model for simulating overland flow generated on rill and interrill areas of hillslope was done using a data set gathered from a laboratory experimental setup. A rainfall simulator has been constructed together with a 6.50 m × 1.36 m erosion ...

  • Prediction of longitudinal dispersion coefficient using laboratory and field data: relationship comparisons

    Knowledge of dispersion of pollutants in streams is necessary for the determination of both the acceptable limits of effluent input and the concentration along the river course. In the far-field, the primary variation of concentration is in one direction and termed longitudinal dispersion; it is independent of the geometrical configuration and type of source. The longitudinal dispersion ...

  • The Five Factors of Smart Laboratory Success

    The Five Factors Research organizations are under pressure to cut costs while maintaining or increasing throughput. To improve their operations, many laboratories are considering investments in data management or support and automation systems like ELNs, LIMS or Robotics/HTS. Whatever the change that is introduced, there are many pitfalls on the way to delivery, roll-out and ...

  • Comparison of field and laboratory collected midwave and longwave infrared emissivity spectra / data reduction techniques

    Abstract Many targets that remote sensing scientists encounter when conducting their research experiments do not lend themselves to laboratory measurement of their surface optical properties. Removal of these targets from the field can change their biotic condition, disturb the surface composition, and change the moisture content of the sample. These parameters, as well as numerous others, ...

  • Method for outlier detection: a tool to assess the consistency between laboratory data and ultraviolet–visible absorbance spectra in wastewater samples

    Reliable estimations of the evolution of water quality parameters by using in situ technologies make it possible to follow the operation of a wastewater treatment plant (WWTP), as well as improving the understanding and control of the operation, especially in the detection of disturbances. However, ultraviolet (UV)–Vis sensors have to be calibrated by means of a local fingerprint ...

  • Testing WHAM‐FTOX with laboratory toxicity data for mixtures of metals (Cu, Zn, Cd, Ag, Pb)

    The WHAM‐FTOX model describes cation toxicity to aquatic organisms in terms of (a) accumulation by the organism of metabolically‐active protons and metals at reversible binding sites, and (b) differing toxic potencies of the bound cations. Cation accumulation (νi in mol g‐1) is estimated through calculations with the WHAM chemical speciation model by assuming that organism binding sites can be ...

  • Forward osmosis desalination from laboratory to market

    A two-step forward osmosis (FO) desalination process combining both FO and reverse osmosis (RO) systems has been developed by the Centre for Osmosis Research and Applications at the University of Surrey and commercialised by Modern Water plc. In the FO + RO process seawater was used as feed water (FW) and a concentrated aqueous solution was used as a draw solution (DS). By taking ...

  • Providing laboratory results to Risk Assessors from ESdat

    Risk Assessors often have very specific data layout preferences which is quite different to other staff.  Many will use ESdat themselves in order to filter for specific datasets; others prefer to be provided with only a spreadsheet. In either case it is critical that time now be wasted re-formatting data when that can be avoided.  Generally, Risk Assessors prefer one of the ...

  • The AIJ pilot phase as laboratory for CDM and JI

    The Activities Implemented Jointly (AIJ) program has developed about 150 greenhouse gas reduction and sequestration projects in many economic sectors in over 40 countries during the last six years. Most of these projects are rather small and many of them have only been partially implemented due to lack of finance. The lack of emissions credits is the main reason. Only half a dozen investor ...
