Abstract:
... A distributed-framework basin modeling system (DFBMS) was developed to simulate the runoff generation and movement on a basin scale. This study is part of a series of papers on DFBMS that focuses on the hydraulic calculation methods in runoff concentration on underlying surfaces and flow movement in river networks and lakes. This paper introduces the distributed-framework river modeling system (DF ...

Abstract:
... The morphological characteristics of yardangs are the direct evidence that reveals the wind and fluvial erosion for lacustrine sediments in arid areas. These features can be critical indicators in reconstructing local wind directions and environment conditions. Thus, the fast and accurate extraction of yardangs is key to studying their regional distribution and evolution process. However, the exis ...

Abstract:
... Production of bulky raw silk is preferred for weaving sarees in Indian context. It was thought to increase the speed of movement of cocoons by incorporating suitable device so that entanglement in filaments will take place resulting in different structure of bulky silk yarn. CSTRI has developed a mechanism to rotate the inner vessel keeping the outer vessel constant; thus, the water would not be s ...

Abstract:
... Local site effects can amplify seismic shaking and damage caused by earthquakes. Site factors (SF) are used in seismic design to account for these effects to modify ground motions from a reference rock site. Average shear wave velocity in the top 30 m of soil (Vₛ,₃₀) is typically used to predict SF. However, recent studies have shown that using Vₛ,₃₀ alone may be insufficient in quantifying SF und ...

Abstract:
... Under irradiation conditions, excess point defects interact strongly with the solute atoms in fusion reactor materials. The solutes can bind with point defects and form clusters such as solute–vacancy complexes. The evolution of these complexes at long timescale significantly influences the mechanical properties of the irradiated materials. In this study, we mainly use climbing image nudged elasti ...

The results demonstrate that the success rate is largely dependent on site-taphonomy, in particular the speed of covering of the site. Sites quickly covered by aeolian, alluvial or marine sediments yield ...

Abstract:
... Flow duration curves (FDCs) represent the percentage of time (or duration) during which a given streamflow is equaled or exceeded. Flow duration curves provide a rapid and direct response to the behavior of water resources in a basin. Thus, predicting FDCs is important in basins with little or no monitoring for both all-time and seasonal periods. The geostatistical approach for predicting FDCs at ...

Abstract:
... River floodplains and reservoirs interact throughout a basin drainage network, defining a coupled human-water system with multiple feedbacks. Recent modeling developments have aimed to improve the representation of such processes at regional to continental scales. However, most large-scale hydrological models adopt simplified lumped reservoir schemes, where an offline routine is run with inflows e ...

Abstract:
... The Congo Basin region is believed to be the site of the cross-species transmission event that yielded HIV-1 group M (HIV-1M). It is thus likely that the virus has been present and evolving in the region since that cross-species transmission. As HIV-1M was only discovered in the early 1980s, our directly observed record of the epidemic is largely limited to the past four decades. Nevertheless, by ...
