The choice of glucose-lowering therapy (GLT) has expanded to include 11 different classes in addition to insulin. Since the 2008 Food and Drug Administration guidance for industry and mandate of demonstrating cardiovascular (CV) safety prior to any new drug approval, there were several trials primarily conducted to establish that goal. Some had neutral effects, while there were positively benef...
abstract decadal changes in land use/land cover for balachaur watershed in nawanshahar district, punjab, india were studied using black and white aerial photographs for march 1984 on approximately 1:20,000 scale and multidate geocoded false colour composites (fcc) of irs-1d liss-iii on 1:50,000 scale for march 2002, september 2002, and may 2003 and interpreted visually to prepare land use/land ...
We consider the generation of a non-perturbative superpotential in F-theory compactifications with flux. For models with a single volume modulus, we show that the volume modulus is never stabilized by either abelian instantons or gaugino condensation. We then comment on how our analysis extends to a larger class of compactifications. From our results, it appears that among large volume string c...
[1] Using internally consistent albedo, aerosol, cloud, and surface data from the Multiangle Imaging Spectroradiometer (MISR) instrument onboard the Terra satellite, top-of-atmosphere (TOA) spectral albedo change (da) in the presence of aerosols over land is estimated and its dependence on aerosol and surface properties is analyzed. Linear regressions between spectral TOA albedo and aerosol opt...
One of the detailed and useful ways to develop land use classification maps is use of geospatial techniques such as remote sensing and Geographic Information System (GIS). It vastly improves the selection of areas designated as agricultural, industrial and/or urban sector of a region. In Islamabad city and its surroundings, change in land use has been observed and new developments (agriculture,...
Tropical deforestation is of growing concern to the world community. Global effects associated with this process include loss of biodiversity and changes in the carbon cycle. Although the importance and present severity of these two externalities are subjects of intense controversy, few would deny the cata strophic nature of their potential impacts. Deforestation also poses local and regional ...
The image of the colonisation of the land by plants as a spectacular event, when barren wastes suddenly became verdant triggered by a change in some extrinsic environmental factor, is fading. It derived from the appearance and rapid diversification of vascular plants, unequivocal land colonisers, and, almost simultaneously, the earliest terrestrial arthropods, in the late Silurian and early Dev...
Soil erosion associated with non-point source pollution is viewed as a process of land degradation in many terrestrial environments. Careful monitoring and assessment of land use variations with different temporal and spatial scales would reveal a fluctuating interface, punctuated by changes in rainfall and runoff, movement of people, perturbation from environmental disasters, and shifts in agr...
It was shown in a recent study [De Jong IC, Prelle IT, Van de Burgwal JA, Lambooij E, Korte SM, Blokhuis HJ, Koolhaas JM. Effects of environmental enrichment on behavioral responses to novelty, learning and memory and the circadian rhythm in cortisol in growing pigs. Physiol Behav, in press.] that barren housed pigs (small pens, no substrate) have a blunted circadian rhythm of salivary cortisol...
