The aim of this study was to investigate and to quantify the effect of burial depth on seedling emergence of volunteer canola and wild mustard. Seeds were buried in 12 different depths (1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 30 cm) in 4 replications and seedling emergence was measured daily. Results indicated that emergence percentage of volunteer canola was around 98 % from 1 to 2.9 cm of burial...

Core body temperature cooling during avalanche burial results in hypothermia, and further core temperature cooling during extrication and evacuation of an avalanche burial victim may result in more severe hypothermia. We performed two studies measuring the rate of core body temperature cooling during snow burial and after extrication from snow burial. Subjects were completely buried in a large ...

Neoproterozoic carbon isotope excursions are commonly attributed to changes in the global fraction of organic burial associated with climate instability and/or oxygenation. Here we show that carbonate sediment deposited during ca. 661 – <651 Ma Cryogenian non-glacial interlude between Sturtian and Marinoan glaciations exhibit lateral offsets carbonate-carbon values from coeval units by as much ...

The hydrocarbon-bearing formation of Miano gas field belongs to the Early Cretaceous and it is bounded by two shale intervals, which are considered as maximum flooding surfaces (MFS). interval includes reservoir units: a tight its overlying conventional reservoir. Core samples, borehole logs, well production performance revealed that reservoirs present reversed trends in quality through without...

Abstract Palaeozoic stromatoporoids, throughout their 100-million + year history (Middle Ordovician to Late Devonian and rare Carboniferous), are better preserved than originally aragonite molluscs, but less well-preserved low magnesium-calcite brachiopods, bryozoans, trilobites corals. However, the original mineralogy of stromatoporoids remains unresolved, details diagenesis patchy. This study...

The red beds of the Buntsandstein (Early Triassic) in Campine Basin (NE Belgium) display porosities between 5.3–20.2% (average 13.7%) and permeabilities varying 0.02–296.4 mD 38.7 mD). Knowledge their reservoir controlling properties, which today are missing, is important view potential geological storage CO2 or natural gas geothermal within these sandstones. Therefore effects diagenesis were a...

Cretaceous shales from the emerging gas province of Rovuma basin are examined using well-log data two exploration wells. The P-wave acoustic impedance (AIp) were estimated, and then brittleness ductility assessed within framework Reuss–Voigt limits for impedance. We predicted shale consolidation a weighting function (Wc) which varies between 0 case grains in suspension (the Reuss limit) 1 conso...

The foot and mouth disease (FMD) outbreak that occurred in the United Kingdom in 2001 was of an unprecedented scale and severity and presented a massive logistical challenge to Government. Over 6.5 million animals were slaughtered and disposed of, over 4 million as a direct result of disease and a further 2.5 million on welfare grounds. On-farm burial and on-farm burning were the principal rout...

Many studies have investigated the individual effects of sedimentation or inundation on the performance of wetland plants, but few have examined the combined influence of these processes. Wetland plants might show greater morphological plasticity in response to inundation than to sedimentation when these processes occur simultaneously since inundation can negate the negative effects of burial o...
