The test results indicated that partially substitutions of oil palm shell with oil-palm-boiler clinker could significantly reduce long term drying shrinkage of concrete.
It seems likely that some combination of the BGC-LV and BGC-SW indices would be able to capture fire risk under both short and long term drying conditions, but this would doubtless require region-specific parameterization and is well beyond the scope of this initial exploratory study.
Recent rain and snow have pushed state precipitation totals above the average for December, but this appears to be "a short-term aberration in an overall long-term dry pattern," Victor Murphy, a southern regional official with the National Weather Service, said in an e-mail.
The study showed that the energy flux to net primry productivity was a small, long-term sink of energy but this sink was a virtue of high carbon accumulation in peat catchments: in catchments where there is no long-term dry matter accumulation, net primary productivity must be a small net source of energy.
I spoke to some people who experienced long-term dry spells about what it was like and how they eventually broke the seal.
The PDSI value is based on the soil water budget model and indicates cumulative long-term dry (negative) and wet (positive) weather conditions for a period spanning from 750 to 1990 (http://www.ncdc.noaa.gov/paleo/pdsidata.html) [52], [53].
The morphological ageing symptoms of the stored seeds resembled those observed after ageing under long-term dry storage conditions.
However, it still remains unknown about how and to which extent temperature can shape microbial communities during long-term dry anaerobic digestion.
This is the first study showing that short-term and long-term dry needling at distant MTrSs can induce suppression of SP levels in the proximal muscle and spinal cord dorsal horns.
Thus storage of lettuce seeds under EPPO conditions resulted in symptoms comparable to those observed with the lettuce seeds after long-term dry storage in a commercial warehouse: delay in radicle protrusion, reduction of total germination, smaller seedlings, abnormal seedlings with mid-vein necrosis and cell membrane leakage.
Hamilton said that cracks in the concrete were merely the result of long-term drying and shrinkage, but said the DoE was planning to carry out cosmetic repairs in order to restore public confidence.
