Increasing applications of ionic liquids and their analogues, namely Deep Eutectic Solvents (DESs), requires further investigation into the effect of moisture content on the physico-chemical characteristics of these fluids. Although it is common practice to synthesize these fluids in a moisture-controlled environment, as moisture is generally considered to have an impact on their properties, th...
Soil moisture is a key variable in dryland ecosystems since it determines the occurrence and duration of vegetation water stress and affects the development of weather patterns including rainfall. However, the lack of ground observations of soil moisture and rainfall dynamics in many drylands has long been a major obstacle in understanding ecohydrological processes in these ecosystems. It is al...
Performance of a tractor mounted solar-biomass hybrid dryer which utilise combined energy solar and biomass was investigated. Drying behaviour maize grains in the also investigated using 10 thin-layer mathematical models. The models were compared based on coefficient determination (R2) root mean square error (RMSE) values between experimental predicted moisture ratios. Moisture content (MC) red...
Soil-gas diffusivity and its variation with soil moisture plays a fundamental role in diffusion-controlled migration of climate-impact gases from different terrestrial agroecosystems including cultivated soils managed pasture systems. The wide contrast texture structure (e.g., density, aggregation) agriculture topsoils (0–10 cm) makes it challenging for soil-gas predictive models to make accura...
Wildland firefighters work in unfavourable environments involving both heat and moisture. Moisture in clothing systems worn by wildland firefighters may increase or decrease heat transfer, depending on its source and location in the clothing system, location on the body, timing of application and degree of sorption. In this experiment, 4 outerwear/underwear combinations were exposed to 1 of 5 d...
This research was carried out at the laboratories of Food Science Department, Faculty of Agriculture, Damascus University, to investigate the effect of high temperatures on accelerating the ripening of kachcaval cheese, through determining the chemical and sensory indicators of ripened cheese using three temperatures (16°C, 20°C for a week) then completing the ripening process up to 60 days at ...
We have examined some of the characteristics of moisture advection and its relation to precipitation over Australia. Seasonal extremes of moisture advection have changed considerably during the latter part of the 20th century. Analysis of its skewness reveals that the relative occurrence of these events has increased. A kurtosis analysis shows that there has been a geographical shift of where t...
Drying has been widely studied as a necessary process in biomass utilization. The steam diffusion law plays an important role drying kinetics. kinetics of single particle using Fick’s second was this paper. A parabolic relationship appeared between the critical moisture content and temperature. decreased with increase temperature initial content. had significant effect on effective diffusivity ...
