Environmental determinism is often used to explain past social collapses and predict the future of modern human societies. We assess availability natural resources resulting carrying capacity (a basic concept environmental determinism) through a toy model based on Hurst–Kolmogorov dynamics. also highlight role cohesion, we evaluate it from an entropic viewpoint. Furthermore, make case that, whe...

Progressive collapse is defined as the spread of an initial damage from one member to another, leading to extensive partial or total collapse of the structure. In this research, the potential of progressive collapse due to a sudden removal of vertical load-bearing elements in reinforced concrete buildings structures with different floor plans such as geometrical regular and irregular floor plan...

Estimation of collapse performance is primarily conducted through Collapse Fragility Curves (CFC’s). The EDP-based approach is the main scheme for attaining such curves and employs IDA. Obtaining CFC’s from IDA results is tremendously time consuming and computationally demanding. Introduction of more efficient methods of seismic analysis, can potentially improve this issue. The Endurance Time (...

in the first impounding of rockfill dams, additional settlements occur in upstream side in saturated rockfills due to collapse phenomenon even high rainy seasons can cause additional deformation in the dumped rockfills. unfortunately these displacements are not taken into account in the conventional numerical models which are currently used to predict embankment dam behavior during impounding. ...

The damming of a river causes dangerous consequences on structure of the environment downstream of the dam, modifying the sediment composition, which impose major adjustments in longitudinal distribution of benthic community. The construction of Engenheiro Sérgio Motta Dam in the Upper Paraná River has caused impacts on the aquatic communities, which are not yet fully known. This work aimed to ...

Non-leptonic D meson decays may provide a reliable testbed for the multiquark interpretation of light scalar mesons. In this letter we consider D s decay and show that a 4-quark f 0 (980) meson could induce a decay pattern, which is forbidden for a q ¯ q constituent structure. Experimental tests to probe such possibilities are within reach in the near future.

China's historiographical traditions tell of the successful control of a Great Flood leading to the establishment of the Xia dynasty and the beginning of civilization. However, the historicity of the flood and Xia remain controversial. Here, we reconstruct an earthquake-induced landslide dam outburst flood on the Yellow River about 1920 BCE that ranks as one of the largest freshwater floods of ...

We examine the charmless hadronic B decay modes in the context of R-parity violating (Rp / ) supersymmetry. We try to explain the large branching ratio (compared to the Standard Model (SM) prediction) of the decay B → ηK. There exist data for other observed η(′) modes and among these modes, the decay B0 → ηK∗0 is also found to be large compared to the SM prediction. We investigate all these mod...

Three qRules governing the collapse of a wave function are given in another paper. In most situations the predictions of this theory are identical with the predictions of other foundation theories. However, there is at least one experiment in which the qRules predict results that are characteristically different from other theories. These results are shown to be a function of temperature and pr...
