Changes in Membrane Lipids during Ice Encasement
The physical properties and chemical composition of microsomal membranes were examined during a 7 day period of ice encasement in crown tissue of winter wheat (Triicum aestivum L. cv Norstar). Membrane damage, detected as an increase in microviscosity and electrolyte leakage, began between 1 and 3 days of icing, and was associated with a reduction in the recovery of microsomal membranes from st...
متن کاملInteractions among Flooding, Freezing, and Ice Encasement in Winter Wheat.
Exposure of winter wheat (Triticum aestivum L.) to various combinations of flooding and freezing stresses induces much greater damage than the individual stresses. Cold-hardened plants flooded for 1 week or exposed to -6 degrees C for 1 week show 100% survival, while survival of plants exposed to both stresses simultaneously is reduced by 20 to 30%, and cold hardiness decreases by several degre...
متن کاملHigh density amorphous ice from cubic ice.
Supercooled water does not behave like a simple liquid, but instead shows a number of anomalous properties. These include the diffusion coefficient [2] or the kinematic viscosity [3] which show anomalous pressure dependencies on compression up to 200MPa, whereas beyond 200 MPa the expected behaviour is observed. To explain these anomalies the second critical point hypothesis has been put forwar...
متن کاملThe Status of BIM Adoption on Six Continents
This paper reports the worldwide status of building information modeling (BIM) adoption from the perspectives of the engagement level, the Hype Cycle model, the technology diffusion model, and BIM services. An online survey was distributed, and 156 experts from six continents responded. Overall, North America was the most advanced continent, followed by Oceania and Europe. Countries in Asia per...
متن کاملIsolated populations of a rare alpine plant show high genetic diversity and considerable population differentiation.
BACKGROUND AND AIMS Gene flow and genetic variability within and among alpine plant populations can be greatly influenced by the steep environmental gradients and heterogeneous topography of alpine landscapes. In this study, the effects are examined of natural isolation of alpine habitats on genetic diversity and geographic structure in populations of C. thyrsoides, a rare and isolated European...
