Equilibrium moisture contents (EMCs) and diffusion coefficients of a high pressure laminate (HPL) overlay, a wood particleboard (PB) substrate, and an HPL backer (BCK) were measured at different levels of relative humidity (RH). The EMCs as a function of RH were fitted to the Nelson's sorption isotherm. It was found that Nelson's model reproduced accurately the experimental data of these differ...

Milled rice kernels have been shown to rapidly fissure and eventually break when exposed to certain air conditions (Stermer 1968, Kunze and Hall 1967, Siebenmorgen et al 1998). Milled kernels rapidly gain or lose moisture from the environment depending on the air temperature and relative humidity (RH) of the surrounding air, as well as the moisture content (MC) of the kernels (Kunze and Choudha...

Soil organic carbon (SOC) is an essential property for soil function, fertility and sustainability of agricultural systems. It can be measured with visible and near-infrared reflectance (VIS-NIR) spectroscopy efficiently based on empirical equations and spectra data for air/oven-dried samples. However, the spectral signal is interfered with by soil moisture content (MC) under in situ conditions...

The aim of this work was to determine the appropriate moisture regime, attained by leachate recycling, to achieve the highest municipal solid waste (MSW) biodegradation rate. To this end, leachate characteristics, methane production rate and changes in degraded refuse were studied. Twenty laboratory-scale bioreactors were loaded with MSW from the landfill of Pátzcuaro (Mexico), four were used a...

Native jackfruit seed starch (JFS) contains 30% w/w type II resistant starch (RS2) and can potentially be developed as a new commercial source of RS for food and pharmaceutical application. Heat-moisture treatment (HMT) was explored as a mean to increase RS content of native JFS. The effect of the conditions was tested at varied moisture contents (MC), temperatures, and times. Moisture levels o...

Moisture content (MC) of poultry manure or litter affects its ammonia (NH 3 ) emissions. Relating MC to ammonia emission of manure or litter is thus of importance to modeling and/or managing ammonia emissions from the manure sources. Development of such relationships would require the knowledge of ammonia emission and the concomitant MC of the manure or litter. This work was carried out to char...

In this study, Cynara scolymus L. leaves aqueous extract powder was produced using a novel spray drying approach by incorporation of ongoing ultrasonic atomization and vacuumed drying chamber. A Response Surface Methodology (RSM)-based central composite face-centered design was employed for optimization of the operating conditions of the ultrasonic vacuum spray dryer. The independent variab...

Kernel-to-kernel moisture content (MC) distributions on panicles were measured for rice cultivars Bengal, Cypress, and Drew. Rice panicles in Arkansas were harvested at different stages of maturity from foundation seed fields at two locations with widely varying soils during the autumns of 1998, 1999, and 2000. The objective was to quantify variability of individual rice kernel MCs as affected ...
