The wide range of optimal values reported for the physical parameters of compost mixtures suggest that their interactive relationships should be investigated. The objective of this study was to examine the microbial O(2) uptake rate (OUR) in 16 sludge waste recipes, offering a range of moisture content (MC), waste/bulking agent (W/BA) ratio and BA particle size levels determined using a central...

The effect of various combinations of temperature and relative humidity on dormancy alleviation of sunflower seeds during dry after-ripening was investigated. The rate of dormancy alleviation depended on both temperature and embryo moisture content (MC). Below an embryo MC of 0.1 g H(2)O g(-1) dw, dormancy release was faster at 15 °C than at higher temperatures. This suggests that dormancy rele...

Dielectric-based methods were used to determine nondestructively and simultaneously bulk density and moisture content in shelled peanuts from measurement of their relative complex permittivity at microwave frequencies (7–12 GHz) and 24 C. The first method is based on direct relationships between the two components of the relative complex permittivity (dielectric constant and dielectric loss fac...

agglomeration followed by pelleting is an efficient method to decrease transport costs and increase economic efficiency of composting municipal waste. the moisture content of compost is the most important parameter of the pellet making process for any type of manufacturing device. the experiments in this study were done at moisture contents of 35%, 45% and 50% at extruder shaft rotational speed...

T HE effects of oven drying temperature and drying time on whole-kernel, long-grain rough rice moisture content determination were investigated for different moisture content levels ranging from approximately 9 to 22% (w.b.). The results showed that a simplified oven method can be used for rapid moisture measurement with accuracy comparable to that of a standard Association of Official Analytic...

This experiment compared commercially available moisture meters (three capacitive metersand one resistance meter) and tested their predictive ability at different conditions on selected beech (Fagus sylvatica) spruce (Picea abies (L.) Karst.) wood samples. The measurements were carried out the samples specified intervals ranging from 5% to 30% content (MC). meter showed a close correlation grav...

Using the Monte Carlo (MC) method, this paper derives arithmetic and geometric means and associated variances of the net capillary drive parameter, G, that appears in the Parlange infiltration model, as a function of soil texture and antecedent soil moisture content. Approximate expressions for the arithmetic and geometric statistics of G are also obtained, which compare favourably with MC gene...

Papayas are one of the most consumed fruits in world. Enriching papayas with isomaltulose and calcium through osmotic dehydration (OD) is a noteworthy strategy for providing these substances to consumers. The present study evaluated influence application vacuum addition lactate an solution (35%) on OD papaya. Papaya cubes edge length 10 mm were immersed solutions, or without lactate, total time...

Twenty agroforestry systems consisting of different management practices (conventional and organic) shade types were set up for coffee plantations in 2,000 at the Tropical Agricultural Research Higher Education Center (CATIE), Turrialba, Costa Rica. The physical (density, bulk density, moisture content, roasting loss) chemical attributes (mineral, total lipid, fatty acids, caffeine, carbohydrat...

niture-grade plywood. The information is greatly needed for manufacturing, buyUltimate screw withdrawal loads (USWLs) from panel face and edge of furnitureing and selling plywood panels, and for grade southern pine (Pinus spp.) and sweetgum (Liquidambar styraeiflua L.) plywood better construction of ]plywood joints in were evaluated at five moisture contents (MCs).
