To investigate the effects on moisture sorption behavior of wood caused by the removal of chemical components, Populus euramericana flour (40 to 60 mesh) was divided into four groups: untreated, extractives removed, hemicellulose removed, and matrix removed. The samples at the fiber saturation point and under oven-dried conditions were separately exposed to relative humidities of 11%, 45%, and ...

An NMR imaging technique published in literature was adapted to investigate the role of glass transition on Fickian and non-Fickian modes of moisture transport in pasta. The modified technique allowed measuring the moisture distribution in samples with initial moisture content from 10% to 50% or higher. A change in slope in the signal intensity versus moisture content curves indicated different...

A laboratory-scale fermentor designed for solid-substrate fermentation was constructed and tested. Its capacity to produce ochratoxin under varied conditions was determined with wheat as substrate. Ochratoxin yields of 2,000 to 2,500 mug/g of wheat were regularly obtained, and occasionally yields as high as 4,000 mug/g were obtained. The most critical factor in the fermentation was initial subs...

Different methods have been applied to recycle pistachio’s green hulls, the most important of which are siloing and drying pistachio hulls (using industrial dryers). In both methods, hulls should lose their initial moisture content, which constitutes a considerable portion of their weight. The high moisture content takes more time and energy during the drying process. The initial dewateringof h...

A dynamical forecast model is applied to study thlJ moisture variation in the planetary boundary layer under the chosen synoptic condition. The observed l2-hour moisture patterns are compa.red with the forecast patterns. Four numerical experiments, using the same initial data on 0600 CST, March 25, 1967, are made. However, in one case only the effects of evaporation from the Gulf of Mexico, and...

It has been proposed that the impact of moisture on atmospheric eddy circulations can be approximated using a reduced effective stratification defined in terms of a parameter λ, which quantifies the asymmetry between upward and downward motions. Here λ is analyzed for the midlatitude regime using baroclinic lifecycles computed with the Weather Research and Forecast model. Vertical velocities ar...

Soil moisture predictability and the associated predictability of continental climate are explored as an initialvalue problem, using a coupled land–atmosphere model with prescribed ocean surface temperatures. Ensemble simulations are designed to assess the extent to which initial soil moisture fields explain variance of future predictands (soil moisture, near-surface air temperature, and precip...

The effect of the initial moisture content (X(0)) of amaranth seeds on expansion volume after popping was examined in hot air and superheated steam (SHS), using a fluidized bed system (FBS). The moisturized seeds were prepared under various vapor pressures due to various saturated salt solutions. In hot air, the maximum expansion volume was shown by seeds having X(0) of 0.16 at 260 degrees C fo...

Drying data for individual rice kernels and bulk samples selected from various tillers of a plant and from different maturity groups were experimentally obtained. The data showed that over 93% of the drying occurred within 24 h of exposure to air at 40° C and 60% relative humidity. Differences in the equilibrium moisture content and drying rate constant among kernels were observed. Equilibrium ...

The adsorption study was conducted on three Japanese soils with different soil properties to characterize the adsorption pattern of Arsenic (As). Double tube method was used to find out the effect of soil moisture levels on As adsorption. For this study, besides double tube method, conventional batch method also was used. The As adsorption showed two phase kinetics. An initial and rapid adsorpt...
