soil compaction and moisture content are two of the factors that greatly influence variations in crop yield. capacitance-based sensor is a sensitive device for estimating soil water content. in this method of soil moisture content measurement, soil acts as the dielectric of the capacitor. throughout this research work, a capacitance-based moisture sensor that can measure the soil moisture conte...

Conventional techniques for the determination of moisture content in grain often use small static samples to represent several tons of material, A more desirable alternative would be a method which utilizes continuous dynamic moisture measurement of the grain. The potential for making density-independent moisture content measurements in both static and flowing grain using microwave frequencies ...

Characterizing the moisture loss from felled trees is essential for determining weight-to-volume (W-V) relationships in softwood sawlogs. Several factors affect moisture loss, but research to quantify the effects of bole size and harvest method is limited. This study was designed to test whether bole size, harvest method, environmental factors, and the associated changes in stem moisture conten...

rice is usually harvested at a high moisture content therefore it must be subjected to drying till the moisture below 14% and for longer storing till 12%. in this project a fixed laboratory dryer was selected for drying three varieties with three range of temperature 40, 50 and 60 c and two range of final moisture content 12% and 10% as completely randomized design. correlation of crack kernel ...

Water sorption isotherms and effective moisture diffusivities were determined at 20 8C for sponge cakes at high water activity as a function of their initial porosity, in the range 86 and 52% (0 g/g dry basis fat content), and of their fat content, ranging between 0 and 0.30 g/g dry basis (67% initial porosity). The equilibrium moisture values were not affected by food structure and decreased w...

Supercritical CO2 extraction of carotenoids from tomato industrial wastes (mixture of skins and seeds) was carried out in a flow apparatus at the temperature of 60 oC and the pressure of 300 bar. The effect of the moisture content (4.6, 23 and 58%), particle size (0.15, 0.35 and 0.72 mm) and solvent flow-rate was studied. The carotenoids recovery (mass of extracted compounds by supercritical CO...

In this study, we determined using NIRS the heritability percentage of amylose, protein, and moisture content in polished and unpolished rice in a CNDH population derived from a cross between Cheongcheong and Nagdong rice varieties. The results revealed a higher heritability percentage for the amylose content and compromised heritability for protein and moisture contents. We also conducted QTL ...

The effects of variable moisture content, screw speed and barrel temperature on the physicochemical properties of red ginseng powder extrudates were investigated. The raw red ginseng powders were processed in a co-rotating intermeshing twin-screw extruder. Primary extrusion variables were feed moisture content (20 and 30%), screw speed (200 and 250 rpm) and barrel temperature (115 and 130°C). E...
