Forest canopy moisture content is an important factor in determining forest fire risk and forest fire behaviour. In Dargon 2 project, to develop a suitable regional early warning technique to predict forest fire risk, a Normal Difference Water Index (NDWI), which has been calculated by using the reflectance of SWIR and NIR band of HJ-1B IRS, has been used to retrieve forest canopy moisture cont...
Contemporary engineering design practices in the United States require information on the strength of lumber for moisture contents as low as 4 percent. Efficient design of experimental studies on lumber properties at low moisture contents requires a better understanding of the basic mechanisms controlling moisture-property relationships. Studies were conducted on the effect of moisture content ...
Corn moisture content is the main factor of effecting corn safe transportation and storage, and is also an indispensable measurement part when it is used to feed, food and industry. Due to large particle size, corn will produce large gap during measuring moisture content. Because air has much influence on dielectric constant of the device, moisture content is not precision. In all kinds of corn...
In this study, we used a model bio drying reactor to optimize the of municipal solid waste (MSW). Two methods aeration were used: one involved controlling concentration oxygen (16–20%) and other temperature in upper part (temperature 42–45 °C, 16– 20%). terms moisture content, highest increase recorded was 0.94% decrease 27.54%. The lower calorific value 9.23% 41.12%. energy balance all trial r...
In this paper, the modelling and control of the moisture content of the particles in a batch Fluidised bed dryer are studied. First, a lumped mechanistic model is developed to describe the heat and mass transfer between solid, gas and bubble phases and experimental validation shows that the model can be used to predict the particle moisture content and temperature profiles during the drying pro...
Almost all properties of grains and seeds depend on moisture content. One of these properties is dielectric constant. Therefore capacitive sensor is used in precision agriculture widely. In this paper, a cylindrical capacitor was used to measure dielectric constant of seed. By measuring the dielectric constant, the moisture content of grains may be predicted. Change in dielectric constant of co...
Nineteen Mediterranean natural soils with a wide range of properties and the Organisation for Economic Co-operation and Development (OECD) artificial soil were used to assess the influence of soil properties on the results of avoidance and reproduction tests carried out with the soil collembolan species Folsomia candida. Compared to natural soils, the OECD soil was mostly rejected by individual...
