Investigating Moisture Gradient-Induced Warpage of Veneers
… or warpage, of wood veneers caused by changes in moisture content affects the ability to press flat panels. To understand wood panel warpage, experimental methods are developed to create and measure moisture-induced deformation of wood veneers on five species of various thicknesses. Three moisture …

Moisture Gradient Measurement During Kiln Drying of Red Oak
… lies in understanding and controlling moisture movement during drying. As wood dries, strains and stresses develop as a result of restraints imposed by moisture gradients and differential shrinkage in wood. So accurately measuring the moisture gradient in wood during drying will be …

Soil and plant water stress in an Appalachian oak forest: its relationship to topography and forest site quality
… and slope position was used to investigate soil moisture and plant water stress relationships on the southeast face of Potts mountain in Craig County, Virginia. Topographical effects on available water are especially pronounced during low late season rainfall levels encountered in the Ridge and …

Measurement of wood moisture content above fiber saturation point by electrical resistance
… As most drying defects occur when the lumber moisture content is above fiber saturation point (FSP), measurement of moisture content (MC) above FSP is critically important. In this study, a technique was developed which permits use of an electrical resistance moisture meter RDX-1 (Delmhorst …

Animal-habitat relationships in the Knysna forest : discrimination between forest types by birds and invertebrates
… undisturbed forest types along a dry-wet soil moisture gradient. Using discriminant functions analysis, a 100% floristic and a 78% vegetation structural discrimination was obtained between the three forest types. However, the bird communities of these floristically and structurally different …

Development of a simulation model for drying deformation in radiata pine boards
… and knot types were illustrated. During drying, moisture desorption in timber results in deformation. In order to use an appropriate partial differential equation for moisture movement in timber, Fick's second law was expanded by further incorporating the effects of mass velocities and thermal …

Ecological studies of fungi growing on isolated wood
… influence of insolation on the temperature-and moisture ranges in wood was investigated. Temperatures up to 160C above ambient were recorded as a result of insolation and data is submitted on the diurnal temperature cycle in a block of wood undergoing insolation. It is recorded that colour had …

Ecological Studies of Fungi Growing on Insolated wood
… influence of insolation on the temperature and moisture ranges in wood was investigated. deere up to 16°C above ambient were recorded as a result of insolation and data is submitted on the diurnal temperature cycle in a block of wood undergoing insolation. It is recorded that colour had no …

Controls on terrestrial carbon and nutrient cycling in Arctic permafrost environments
… cover types exist across a naturally occurring moisture gradient, allowing us to investigate these relationships in wet and mesic tundra. Soil moisture, as opposed to soil temperature, was the main driver of inorganic nitrogen availability; ammonium was dominant under wetter conditions, while …

Radial growth patterns of jack pine in relation to climate, moisture availability, and dwarf mistletoe infection in the Boreal Plains Ecozone of Saskatchewan, Canada
… and uninfected stands, across the regional moisture gradient associated with the boundary of the boreal forest in southern Saskatchewan. I sampled across three study regions extending from remnant island forests in the drier Aspen Parkland Ecoregion, to the wetter interior of the mid-boreal …

Sapling growth and recruitment as affected by flooding and canopy gap formation in a river floodplain forest in southeast Texas
… varies primarily along a flooding/soil moisture gradient, and secondarily along a canopy-openness gradient. This confirms that both flooding and light influence local variation in species composition. Small sapling density increased by more than five times during the decade, while large …

Electrochemical Routes for Capture and Utilization of CO2
… the energy consumption of migration-assisted moisture-gradient (MAMG) capture by nearly 50%. Beyond transport enhancement, ILs were shown to play a previously unrecognized catalytic role in accelerating CO2 hydroxylation by locally pre-activating and bending CO2, thereby lowering activation …

Classifying and Mapping Native Grasslands of South Dakota's Northern Prairie Coteau and Characterizing Habitat for Dakota Skipper Conservation
… data found that axis one represented a moisture gradient (r = .55), while management regime influenced axis two (r = .22). Three plant communities, Upland Dry Prairie, Dry-Mesic Prairie and Mesic Prairie, were revealed using flexible beta (β = -.025) and Sørenson distance, and were …

Phytolith Analysis as a Palaeoecological Tool for Reconstructing Mid-to Late-Pleistocene Environments in the Olorgesailie Basin, Kenya
… vegetation components according to a moisture gradient while Cluster analysis identified unique morphotypes that were taxonomically affiliated to their parent plant species. However, the analyses were not able to distinguish plants along the altitudinal gradient. Fossil phytoliths …

Spatio-Temporal Analysis of Observed Soil Moisture from Nebraska
<p>Soil moisture is a measure of the water content in a soil that is dependent upon precipitation, evapotranspiration, runoff, drainage, and irrigation. Nebraska is one of the few states that measures soil moisture in an extensive network that records weather variables on a daily basis. Daily soil …

THE EFFECTS OF WHOLE TREE HARVESTING ON SITE HYDROLOGY AND SOIL STRUCTURE AT BEDDGELERT FOREST, N. WALES, UK
… tensiometer results were inconclusive. Downslope moisture gradient combined with high conductivity suggested that large quantities of water could be transmitted. Similarly, the well structured surface soil and marked horizon development also indicate lateral flow may be dominant. The study showed …
