  • Measuring CO2 to Optimise the Bulk Storage of Food

    Meeting the food requirements of a growing global population is becoming increasingly difficult. Despite the need for additional food, it is estimated that 50-60% of grain is lost after harvesting, at a cost of about $1 trillion per year.1 One of the major reasons for lost grain is spoilage due to mould or insect infestation during storage.2 To provide a ...

  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • Studies on Geocell Reinforced Road Pavement Structures – Rajagopal, Veeragavan, Chamdramouli, 2012

    Too often, the scarcity or distance of natural resources, makes the strengthening of highway pavements a costly or lengthy exercise. Building on previous studies by Bathurst, Han, Pokharel and others, this study published in Geosynthetics Asia, provides academic proof that NPA Geocell reinforcement increases the stiffness and elastic modulus of pavements. Validation – Field ...

  • How conditions affect cookies and air pollution control solutions

    Chocolate chip cookies are one of my favorite treats. Butter, sugar, eggs, flour, vanilla, and, of course, chocolate chips. Combine the ingredients together and you get a delicious cookie. Somehow, using the same ingredients the cookies do not always turn out the same. Sometimes they are thinner and crispier. Other times, they are soft and chewy. After watching cooking shows, I have come to ...

  • Hydrocarbon in Water Monitors using Fluorescence

    Hydrocarbon in Water Monitors using Fluorescence are capable of detecting hydrocarbons as low as 5 Parts per Billion and as high as 10,000 Parts per Million depending on the application.  Because only the target hydrocarbons will fluoresce, these monitors have no significant affect due to water turbidity (rust, dirt, gas bubbles, soot, etc.).  Fluorescence monitors provide a measurement ...

  • Drinking water quality monitoring using trend analysis

    One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled ...

  • Water Quality Monitoring and Testing Using an Environmental Logger

    Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

  • Monitoring of regional lake water clarity using Landsat imagery

    The application of remote sensing technology to water quality monitoring has special significance for lake management at regional scale. Water clarity expressed in terms of Secchi disk transparency (SDT) is a highly useful indicator of trophic status and ecosystem health. In this study, we related Landsat TM and ETM+ data with ground observations to develop a model for the estimation of SDT ...

  • Water quality monitoring in wetland ecosystems using microbial model communities

    This study reviews the concept of model communities for water quality assessment in aquatic ecosystems. The feeding habits of protozoans were used to unite species into functional, trophic groups. Colonising communities were dominated by bacterivorous Flagellate Species (Sf). A new Index of Periphyton Flagellates (IPF) as an indicator of the trophic status of a water-body was developed. ...

  • A New Multilevel Ground Water Monitoring System Using Multichannel Tubing

    A new multilevel ground water monitoring system has been developed that uses custom-extruded flexible 1.6-inch (4.1 cm) outside-diameter (O.D.) multichannel HDPE tubing (referred to as Continuous Multichannel Tubing™ or CMT) to monitor as many as seven discrete zones within a single borehole in either unconsolidated sediments or bedrock. Prior to inserting the tubing in the borehole, ports are ...

  • A new monitoring method of CRVI in water using boron-doped diamond microelectrodes

    Boron doped diamond electrodes were used for the amperometric measurement of chromiumVI in water. A linear relationship of the current density as a function of the chromiumVI concentration was observed for concentrations comprised between 50 ppb and 4 ppm. Such results are particularly promising for the monitoring of chromiumVI in liquid effluents or process baths of several industries (stainless ...


  • Using PRTR database for the assessment of surface water risk and improvement of monitoring in Japan

    In April 2003, the first PRTR (Pollutant Release and Transfer Register) was published in Japan. It is shown how the PRTR can be used to improve environmental risk assessment with the objective of reducing risk to ecosystem integrity and human health. By examining the superposition of all chemical releases into rivers, high levels of several contaminants are uncovered. Most of these chemicals have ...

  • Heterogeneity of water quality in Huai River, China by using bio-monitoring data

    A new approach by combining bioindicators (BiI) and biotic indices (BIs) for evaluating water quality is presented in this paper. It is then applied to the Huai River Basin (HRB), China, which is well-known globally for its heavy anthropogenic influences. Results indicate that the spatial distribution of BI-indicated water quality has roughly the same pattern as that shown by BiI, but the ...
