The water relations play a fundamental role in seed comprehension of biology. In order to describe the process of drying and the effect on water activity, which controls biological change in storage, a sound knowledge of the relationship between equilibrium moisture content (EMC) and water activity/equilibrium relative humidity (ERH) is essential. The relationship between the total moisture con...

Title of Document: AN EXPERIMENTAL ANALYSIS OF FIREFIGHTER PROTECTIVE CLOTHING: THE INFLUENCES OF MOISTURE AND A THERMALLY ACTIVATED EXPANDING AIR-GAP. James Patrick White, Master of Science, 2012 Directed By: Professor, Marino di Marzo, Department of Fire Protection Engineering Thermally protective clothing garments are necessary pieces of equipment that ensure the life safety of firefighters....

introduction: using oilseeds in the human food stuffs, employing their meal for animal feed and also their usage in pharmaceuticals, soap making and fuel has prompted great interest for farmers to plant them and for the government to promote their cultivation. among them, sunflower is one of the main oilseeds in the world which its cultivated area has expanded due to fair cultivation requiremen...

The simultaneous effect of weight, initial density (kg/m3, temperature and O2 concentration on rainbow trout body composition (fat, protein, moisture and ash) has been studied. In 3 successive experimental phases fish were kept in different lots of varying initial weight (178-372 g), initial density (7.2-38.8 kg/m3) and temperature (15-20 degrees C). Simple correlations were statistically signi...

Thermoplastic properties of extruded sugar beet pulp (SBP) are closely linked to water–polymer relationships. DSC analyses of water evaporation, water fusion and biopolymer relaxation according to SBP moisture content gave a more accurate estimation of SBP hydration steps than classical water adsorption isotherm. Three moisture contents (8%, 26%, 41% db) were then defined as limits of the diffe...

Semi-arid ecosystems with annual moisture inputs dominated by snowmelt cover much of the western United States, and a better understanding of their seasonal drivers of soil respiration is needed to predict consequences of climatic change on soil CO2 efflux. We assessed the relative importance of temperature, moisture, and plant phenology on soil respiration during seasonal shifts between cold, ...

In the present work, the effective moisture diffusivity and activation energy were calculated using an infinite series solution of Fick’s diffusion equation. The results showed that increasing drying temperature accelerated the drying process. All drying experiments had only falling rate period. The average effective moisture diffusivity values varied from 2.807x10 to 6.977x10m s over the tempe...

Efficient processing, handling, and storage of corn stover, a major crop‐based biomass, require an understanding of the moisture sorption thermodynamic properties of its fractions. Moisture sorption thermodynamic properties of the major corn stover fractions such as leaf, stalk skin, and stalk pith were determined, utilizing the static gravimetric sorption isotherms data in the temperature rang...

Characteristics of reflection spectrum, multi-spectral images and temperature of lettuce canopy were gained to judge the lettuce’s water stress condition which could lead to a precise, rapid & stable test of lettuce moisture and enlarged the models’ universality. By the extraction of lettuce’s multisensor characteristics in 4 different levels, quantitative analysis model of spectrum including 4...
