Paleoclimatic studies with multiple proxy data have increasingly improved our understanding of Holocene climate. A dry and warm climate in the early and middle Holocene has been documented by numerous studies in eastern North America (T. Webb et al., 1983, 1993; COHMAP Members, 1988; Baker et al., 1992; R. Webb et al., 1993). Recent studies show that the classic dry and warm prairie period in m...
evaluation growth analysis and grain yield of sunflower cultivars under sowing date in dry condition
sunflower is one of the most important edible oil that growth of annual crops, it is grown over a widely area and is considered a crop adapted to an every environmental conditions, in order to study growth analysis of sunflower under sowing date and cultivars in dry condition a farm experiment was conducted a split plot arranged in a complete randomized block design with three replications in t...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
Paleoclimate was reconstructed by the clay mineral assemblages of shale units of Pabdeh (PaleoceneOligocene), Gurpi (Upper Cretaceous), Kazhdumi (Albian-Cenomanian) and Gadvan (Aptian-Neocomian) formations in the Bangestan anticline. To compare with clay minerals assemblages in these formations, selected samples also taken from available formations in drilled wells in Ahvaz, Marun, Karanj, and ...
Rill erosion is considered to be the most important process affecting soils created by the concentrated flow of water. In this research to quantify sediment transport and runoff in natural rills, two rill experiments under dry and wet conditions were accomplished in November 2013 in the Golestan Dam. Filed experiments lead to a closer understanding of the dynamics and power of different soil er...
Aim: Tuberculosis has high mortality in the world and recently recurring. Nowadays TB incidence is increasing. Observation, follow-up and comparing disease's Incidence would be necessary for prevention, management and control them. The purpose of this study is TB incidence surveillance in different times and places of Iran by GIS. Methods: This study is a retrospective analysis on TB incidence...
The mid-latitudes of East Asia are characterized by the interaction between the Asian summer monsoon and the westerly winds. Understanding long-term climate change in the marginal regions of the Asian monsoon is critical for understanding the millennial-scale interactions between the Asian monsoon and the westerly winds. Abrupt climate events are always associated with changes in large-scale ci...
Earth’s storm tracks are instrumental for transporting heat, momentum, and moisture and thus strongly influence the surface climate. Climate models, supported by a growing body of observational data, have demonstrated that storm tracks shift poleward as the climate warms. But the dynamical mechanisms responsible for this shift remain unclear. To isolate what portion of the storm track shift may...
Climate projections for the future indicate that the United Kingdom will experience hotter, drier summers and warmer, wetter winters, bringing longer dry periods followed by rewetting. This will result in changes in phosphorus (P) mobilization patterns that will influence the transfer of P from land to water. We tested the hypothesis that changes in the future patterns of drying-rewetting will ...
