leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. determining drying characteristics of leather is vitally important so as to optimize the drying stage. this paper describes an analytical way for determination of the drying characteristics of leather. the model presented, is based on fundamental heat and mass transfe...

[1] The subtropical convective boundary layer (CBL) plays a critical role in climate by regulating the vertical exchange of moisture, energy, trace gases, and pollutants between the ocean surface and free troposphere. Yet bulk features of this exchange are poorly constrained in climate models. To improve our understanding of moisture transport between the boundary layer and free troposphere, pa...

Humic substances (HS) reportedly enhance moisture retention of soil. However, no information is available as to the effects of HS on sand-based golf course putting greens. HS have acidic functional groups (COOH) that are reaction sites on the molecule. An greenhouse experiment was conducted to evaluate the effect that the acidic functional groups in humic acid, tannic acid and citric acid have ...

Hazardous contaminants buried within vadose zones can accumulate in soil gas. The concentrations and spatial extent of these contaminants are measured to evaluate potential transport to groundwater for public risk evaluation. Tritium is an important contaminant found and monitored for in vadose zones across numerous sites within the US nuclear weapons complex, including Los Alamos National Labo...

Antecedent moisture conditions are essential in explaining differences the translation of flood-producing precipitation to floods. This study proposes an empirical residual-oriented antecedent index (RAPI) estimate and further link with flood predictive uncertainty. By developing a fully kernel-based residual error model without functional presumptions, proposed RAPI is calibrated as regressor ...

For the several decade years, organic light-emitting diodes (OLEDs) have been intensively studied because of their potential applicability to large-size flat panel displays, and more recently also solid-state lighting [1-4]. However, the lifetimes of the organic electronic devices are one of the most matters for the practical use of such devices, because of the ambient moisture and oxygen immed...

To develop biodegradable packaging that both acts as a moisture barrier and as antimicrobial activity, nisin and stearic acid were incorporated into a hydroxy propyl methyl cellulose (HPMC) based film. Fifteen percent (w/w HPMC) of stearic acid improved film moisture barrier. However, film mechanical resistance and film antimicrobial activity on Listeria monocytogenes and Staphylococcus aureus ...

s of papers 9 The objective of this experiment was to determine differences between 10 breed crosses with regards to eggshell properties and embryo metabolism. Eggs from the flocks (51 to 54 weeks of age) were incubated in a single machine, moisture loss measurements were recorded. Additionally, embryo weight with out yolk (EMB) and residual yolk weight (YLK) were determined at 15, 18 and 21 d....

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...
