Abstract This study examined the influence of moisture content (MC) on NO 2 sorption ability cedar ( Cryptomeria japonica ) wood using specimens with different MCs. Four MC conditions were applied, namely 0%, 8.6%, 12.7% and 16.5%, based differences bonding condition water molecule in substances. As a result, volume increased drastically due to presence water, as increased, slightly. The genera...

The green lumber products tend towards a state of equilibrium with the surrounding environment. The final target is the equilibrium moisture content (EMC). Whether is natural convection in the lumberyard or forced convection in the kiln drier, the road towards the final EMC consumes time and energy. The air drying operations (natural convection) are not an easy task for the drying management. T...

For coal-fired power plants information of the moisture content in the coal is important to determine and control the dynamical behavior of the power plants. E.g. a high moisture content in the coal can result in a decreased maximum load gradient of the plant. In this paper a method for estimating the moisture content of the coal is proposed based on a simple dynamic energy model of a coal mill...

Real-time non-invasive moisture content sensing techniques are needed for online moisture measurement and control in food products. In this investigation, a dielectric spectroscopy based system is used for moisture determination in cookie dough. Experiments were conducted with a concentric ring dielectric sensor in the frequency range from 10 Hz to 10 kHz. The system is calibrated based on a li...

Cyanobacteria are able to produce several metabolites that have toxic effects on humans and animals. Among these cyanotoxins, the hepatotoxic microcystins (MC) occur frequently. The intracellular MC content produced by two strains of Microcystis aeruginosa, PCC7806 and PCC7820, and its production kinetics during the culture time were studied in order to elucidate the conditions that favour the ...

A technique is described for estimating moisture content of small samples of hard red winter wheat (10 to 30 kernels) by impedance measurements at 1 and 4.5 MHz on a parallel-plate capacitor holding the sample between the plates. The measurement system was calibrated by measurements on samples, ranging from 9 to 20% moisture content, wet basis, from three wheat cultivars grown in 1991 and 1992,...

water desorption isotherms of raw and osmotically dehydrated (at 25ºc, for 2 hours, with 10 and 26% nacl solutions) garlic slices at different temperatures (25, 40, 55, and 70ºc) were experimentally determined over a range of water activity of 0.05–0.90 using a static gravimetric method. desorption isotherms can be classified as type iii. the water desorption isotherms of raw garlic clearly sho...

The current paddy drying practice in the rice mill is heating and blowing air continuously to reduce moisture content a certain level (i.e., 12%–14%). stopping time of process determined via manual checking (MC) from time. Several problems inconsistent dried quality excess energy consumption) arise usual due human error. Hence, MC time-series data collected an actual can be related environment ...

Abstract Surface tension of solid wood surfaces affects the wettability and thus adhesion various adhesives coatings. By measuring contact angle wood, surface can be calculated based on Young-Dupré equation. Several publications have reported measured with different test liquids, under conditions. Results only compared if conditions are similar. While roles drop volume, image shooting time etc....
