Inhabiting Wetness
… might it mean instead to inhabit a gradient of wetness by exploring other possibilities for resilient living at the edge? Sited in the Bañado Sur, this project considers these questions in a zone of informal housing that experiences hazardous flooding from heavy rain and river surges. These …

Unsteady Wetness Effects in Low Pressure Steam Turbines
… turbines is crucial for the correct analysis of wetness losses and other two-phase effects. Measurements taken in the later stages of LP turbines have shown broader size distributions with larger average sizes than those predicted by numerical methods. One hypothesis is that the broad …

A smart diaper wetness detection sensor : concept, design and ethical considerations
… individuals, and hospital patients. Diaper wetness-based alerting can enhance care of this population by improving incontinence management, preventing rashes and infections, and avoiding embarrassment. A practical implementation of this consumer-oriented system will directly impact the user, …

Investigating the Illusion of Wetness: Cold Dry Stimuli in Sensory Perception
Humans lack specialized receptors for perceiving wetness and so it is a compound sensation based on changes in skin temperature and contact pressure that are sensed by thermoreceptors and mechanoreceptors in the skin. In addition to perceiving the wetness of damp fabrics in contact with the skin or …

Using Digital Methods to Reconstruct Original Topography and Landscape Wetness in the Judicial Ditch 66 Watershed, Polk County, Minnesota
… parts. First, drainage area and its potential wetness were estimated using the 10 meter U.S. Geological Survey Digital Elevation Model (DEM). The ln(a/tan β) potential wetness index is used, which is directly related to drainage area. Second, points representing ditches and berms were …

Tree Composition Along Edaphic and Hydrologic Gradients in Nonriverine Wet Hardwood Forests
… trends in plant species composition along a wetness gradient. Although quantitative vegetation analysis for this community has been published, broad drainage classes were used to represent a moisture gradient. We investigated trends along a finer-scaled wetness gradient utilizing a novel …

Carbon monoxide clean-up of reformate gas by preferential oxidation
… was tested. The first catalyst was prepared by wetness impregnation at a high pH and the second was prepared by incipient wetness impregnation. Catalytic activity was measured at varying temperatures, space velocities as well as O2/CO ratio. The Ru catalyst catalyst prepared using wetness …

Hydropedology of Problematic Interfluve Transported Soils in the Central Virginia Piedmont
Interpreting soil wetness in upland transported soils on flat broad summits in the central Piedmont of Virginia containing chroma ≥ 3 redoximorphic features (RMFs) can be difficult. It is imperative to understand their saturation regimes because onsite wastewater disposal systems, which are sited …

The contribution of manganese oxides to redox buffering in selected soils of the South African Highveld
… The use of redoximorphic features as a soil wetness indicator is widely practiced. The reduction of Fe3+ to Fe2+, resulting in the formation of these features, is particularly diagnostic for wetland soils. The problem arises when investigating a soil that shows visible wetness but lacks these …

Olive leaf spot: epidemiology and control
… of temperature, relative humidity (RR), leaf wetness and leaf age on conidium germination were investigated for Spilocaea oieagina, the causal organism of olive leaf spot. Detached leaves of five leaf ages (2, 4, 6, 8, and 10 weeks after emergence), six different temperatures (5, 10, 15, 20, …

Epidemiological Factors Affecting Bitter Rot Infection in Vitis vinifera L. in North Carolina
… and influence of temperature and duration of wetness on infection. Detached V. vinifera 'Chardonnay' fruit were inoculated with 10 isolates of G. uvicola obtained from fruit of V. vinifera, V. rotundifolia (muscadine grape), and a French-American hybrid. Isolates HCMD1 and HCMD5, obtained from …

Hydrologic and topographic analyses of bog turtle (Glyptemys muhlenbergii) wetlands
… their groundwater inputs which influences site wetness. To explore relationships between water level dynamics and wetland spatial features, we conducted regression analyses using water level metrics and water temperature regimes (indicators of groundwater seeps) as predictors of the extent of …

Effects of restoration on carbon storage in smelterimpacted industrial barrens
… shrubs, and trees in each plot. Measures of wetness index, plant species richness, soil metal concentrations, soil pH, distance from smelter, and elevation were then used to assess factors affecting total ecosystem C storage. In lowland valleys where no active tree planting occurred (only …
