摘要:Abstract(#br)The magnetic field of the Earth can exhibit considerable variations at short time scales, even as short as decades. The archaeomagnetic studies of Middle Eastern artefacts (mainly from Israel and Jordan) show evidence for an exceptionally high intensity period f...

摘要:Abstract(#br)Genome-wide association studies (GWAS) suggest that Alzheimer’s disease (AD) is partly explained by a burden of risk alleles (single nucleotide polymorphisms; SNPs) with relatively small effects. However, the mechanisms by which these loci cumulatively confer su...

摘要:Abstract(#br)Plants actively regulate excess absorbed energy to protect photosynthetic machinery through heat dissipation in a process known as non-photochemical quenching (NPQ), a process useful for quantifying plant health and productivity. NPQ can be indirectly measured i...

摘要:Abstract(#br)Ponds are among the most biodiverse freshwater ecosystems, yet face significant threats from removal, habitat degradation and a lack of legislative protection globally. Information regarding the habitat quality and biodiversity of ponds across a range of land uses is...

摘要:Abstract(#br)Management of grazing lands has been included in land-based mechanisms for reduction of greenhouse gas emissions. This paper describes a spatial system for scenario analysis of the effect of changes in grazing management on rangeland carbon balances. The system is ba...

摘要:Abstract(#br)Three commercial copolymers, two ethylene-butene and one ethylene-hexene, produced using metallocene catalysts, were each blended with a commercial linear polyethylene to form binary blends of various compositions. The three copolymers had quite similar molecula...

摘要:Abstract(#br)Although there is a great deal of information concerning the risk factors for colorectal cancer, progress has been slow in determining methods of chemoprevention. In part this is because colorectal cancer consists of a series of events over 10–15 years or more, ...

摘要:Abstract(#br)Blends of linear polyethylenes of differing molecular weights ( MW s) have been studied to try to determine whether there is any observable phase separation in the melt. Using four linear polyethylene fractions, of MW s between 2 × 10 6 and 2.5 × 10 3 , blends w...

摘要:Abstract(#br)In this study, spectral indices were calculated from single date HyMap (3 m; 126 bands), Hyperion (30 m; 242 bands), ASTER (15/30 m; 9 bands), and a time series of MODIS nadir BRDF-adjusted reflectance (NBAR; 1 km, 7 bands) for a study area surrounding the Tumba...
