To investigate the mechanism of available energy partitioning to sensible and latent heat fluxes over semi-arid regions, data from the Semi-Arid Climate and Environment Observatory of Lanzhou University (SACOL) were analyzed to assess the effects of soil moisture, net radiation, and vapor pressure deficit (VPD) on available energy partitioning, as quantified by Bowen ratio. It was found that th...

The compression molding of dried fish floss is of great significance to the development of fish product. The compression ratio, relaxation ratio and shatter resistance are selected as the evaluation indicators, effects of particle size, moisture content, amount, and processing methods on the compression molding quality of fish floss are analyzed. The results show that: 1) the moisture content a...

Natural fibers are gaining the interest of scientist and engineering in packaging, low cost housing and other general applications. In the present study, adhesive tensile and moisture absorption properties of randomly distributed areca fibre and maize powder reinforced urea formaldehyde composites has been investigated. Composites were prepared by hydraulic hot press at 150C and 100 bar pressur...

Soil moisture predictability and the associated predictability of continental climate are explored as an initialvalue problem, using a coupled land–atmosphere model with prescribed ocean surface temperatures. Ensemble simulations are designed to assess the extent to which initial soil moisture fields explain variance of future predictands (soil moisture, near-surface air temperature, and precip...

The purpose of this study was to investigate the effect of process conditions on the properties of instant grain base. A blend of wheat, mungbean and groundnut was used in the study. The effects of feed moisture, barrel temperature and screw speed on product responses viz. specific mechanical energy (SME), expansion ratio (ER), density (D), water absorption index (WAI) and water solubility inde...

The condition of oil-paper insulation is closely related to the life expectancy of a transformer. The accurate results of oil-paper have not been obtained due to the impact of influencing factors. Therefore, in order to improve the evaluation accuracy of oil-paper insulation, in this paper, oil-paper samples which were prepared with different aging and moisture content were analyzed by frequenc...

The performance of an incinerator is affected markedly by the moisture content of the refuse. To maintain a satisfactory £ire and a high rate of operation under con� ditions of varying refuse moisture is difficult at best: As the flue gas reflects the refuse analysis, a meter is proposed that would report the ratio of CO, and H,O vapor in the furnace exit gas. The CO2/H20 ratio varies from 2.0 ...

BACKGROUND Excess moisture and visible mold are associated with increased risk of asthma. Only a few studies have performed detailed home visits to characterize the extent and location of moisture damage and mold growth. METHODS Structured home inspections were performed in a birth cohort study when the children were 5 months old (on average). Children (N = 398) were followed up to the age of...
