in determining how a plant responds to moisture deficit stress. Moisture deficits can depress cotton (Gossypium hirsutum L.) lint Although there has been considerable research docuyield in all cotton production regions. However, most cotton physiomenting the growth and physiological response of cotton logical drought stress research has been conducted in arid production to moisture deficit stre...

Thermal imaging has been used in the past for remote detection of regions of canopy showing symptoms of stress, including water deficit stress. Stress indices derived from thermal images have been used as an indicator of canopy water status, but these depend on the choice of reference surfaces and environmental conditions and can be confounded by variations in complex canopy structure. Therefor...

[1] Due to the influence of evaporation on land-surface temperature, thermal remote sensing data provide valuable information regarding the surface moisture status. The Atmosphere-Land Exchange Inverse (ALEXI) model uses the morning surface temperature rise, as measured from a geostationary satellite platform, to deduce surface energy and water fluxes at 5–10 km resolution over the continental ...

A large number of bridges in the federal inventory are reaching the end of their design life due to aging and environmental degradation. The situation is aggravated by increased traffic needs that require existing structures to carry heavier loads at increasingly higher speeds. Project Summary: The issue of moisture diffusion in composite materials is important because of its associated problem...

Phase-change materials (PCM) can be used to reduce thermal stress and improve thermal comfort for workers wearing protective clothing. The aim of this study was to investigate the effect of PCM in protective clothing used in simulated work situations. We hypothesized that it would be possible to optimize cooling performance with a design that focuses on careful positioning of PCM, minimizing to...

Gentle in-store drying of popping corn may reduce the risk of stress fissures being generated, an effect which reduces popcorn expansion volume. In order to allow optimisation studies of in-store drying to be conducted, thermophysical properties of two current Australian popping corn varieties were measured in the range 30-50°C, at moisture contents from 12% to 20% wb. Models were developed for...

• Soil hydrologic parameters including field saturation, field capacity, initiation of plant water stress and plant extraction limits can be reliably determined from electronic soil moisture sensor records. • Soil profile wetting and drying occurs along a regular continuum of soil moisture following the advance of the wetting from to the effective base of the soil profile. • Frozen soil conditi...

The narrow genetic variation of bread wheat is one of the limitations to improve it for drought-tolerance. The research carried out to study the responses of different genotypes and traits to imposed moisture stress. The plant material comprised of 10 Aegilops tauschii accessions as well as a tolerant (BW2) and a susceptible (BW1) bread wheat cultivar. To assess the root and shoot-traits, two s...

STUDY DESIGN T2 mapping was used to quantify moisture content of the lumbar spinal disk nucleus pulposus (NP) and annulus fibrosus before and after exercise stress, and after rest, to evaluate the intervertebral disk function. OBJECTIVE To clarify water retention in intervertebral disks of the lumbar vertebrae by performing magnetic resonance imaging before and after exercise stress and quant...
