|
The final cover integrity inspection is designed to address desiccation of the barrier system. |
|
Usually, they are detected when the crowns of the ash trees start to thin as the leaves start falling off and dying due to desiccation. |
|
In wide areas, these shifts included episodic desiccation from 12,000 or 10,000 bp onward. |

Low risk of carbon monoxide formation due to good resistance of dry gas desiccation. |
|
If they are not controlled, fungal diseases may severely affect plant growth and cause severe leaf desiccation. |
|
The federal government says new restrictions for herbicide residues mean fewer desiccation products are available for dry bean growers. |
|
This project will restore the former conditions to stop further desiccation of the forests. |
|
Dr. Acker's group is working to better understand the effects of desiccation and drying on blood cell structure and function. |
|
|
In their search for food, subterranean termites construct mud tubes because they are susceptible to desiccation when exposed to air. |
|
Its distribution is also limited by salinity, wave exposure, temperature, desiccation, and general stress. |
|
Cultures were moistened with tap water to prevent desiccation and, in the last stages, to help antheridial opening and movement of antherozoids. |
|
These structures may be covered with natural tissue, meshed non-adherent material, or bioengineered tissue to help minimise risk of desiccation or injury. |
|
The great desiccation Days of terror All aboard the freedom train? |
|
Only a few days before Bear's desiccation, remember, some analysts embarrassingly pointed out that it had enough liquid assets and borrowing capacity to keep it going for almost two years. |
|
This led to severe desiccation of the wetlands. |
|
Sugars have been shown to be important stabilizers of membranes, proteins and other key cellular structures in natural systems that undergo extreme environmental stresses such as desiccation and freezing. |
|
For dry agents from sporulating organisms, the spores are separated from the growth medium, washed, dried by desiccation, and stored in sealed vials kept in the dark. |
|
Dramatic changes in flow downstream of works cause substantial problems for both fish and their habitat, Fish and fish eggs may become exposed to desiccation, extreme temperatures and predators. |
|
The available information suggests that while there is potential for desiccation and shrinkage, this can be mitigated by appropriate design and construction. |
|
However, at the concrete spill mentioned above dried desiccation cracks formed in concrete, which closely resemble those found in the fossil record. |
|
The importance of cuticular permeability, osmolyte production and body size for the desiccation resistance of nine species of Collembola. |
|
To prevent desiccation of plant tissues in a terrestrial environment, a waxy cuticle covering the soft tissue of the plant provides protection. |
|
Mussel shells carry out a variety of functions, including support for soft tissues, protection from predators and protection against desiccation. |
|
In the field the fourth-stage juvenile can withstand desiccation for many years, and although soil densities seem to decrease rapidly, the nematode can survive for years without a host plant. |
|
A species' ability to cope with desiccation determines its upper limit, while competition with other species sets its lower limit. |
|
Many mosses can survive desiccation, sometimes for months, returning to life within a few hours of rehydration. |
|
They suggested that microbes had adapted to desiccation, as N was found to be immobilised within 4 h after dry soil was rewet. |
|
Linear desiccation rates also have been observed for some tenebrionid beetles. |
|
|
Diaphysial shrinkage in skeletonised or mummified fetal bones is a direct result of loss of water and organic matrix, such as hyaline connective tissue through desiccation. |
|
Therefore, it is still unclear how the gametophytes, which appear as highly vacuolate, unprotected cells in a single layer, can survive without desiccation or even through it. |
|

|
Though the plant is strong in live, it has a low viability for seeds, and the seeds are in low survival ability too because of desiccation, burial and erosion. |
