Investigation of the effect of using nanomaterials for improving and Stabilizing the gypseous soil was carried out using laboratory works. The gypseous soils were collected from a site of intake in Bahar Al-Najaf and mixed with two types of nanomaterials (Nano-silica and, Nano-clay) where the nanomaterials were added in small amounts as a percent of the dry weight of the soil sample. Tests to d...

in recent years, the trend in solving optimization problems has been directed toward using heuristic algorithms such as neural networks, genetic and ant colony algorithms. the main reason for this trend can be attributed to the fact that these algorithms can be efficiently adjusted to the specific search space to which they are applied and consequently they can be used for many optimization pro...

This study is devoted to seismic collapse safety analysis of performance based optimally seismic designed steel chevron braced frame structures. An efficient meta-heuristic algorithm namely, center of mass optimization is utilized to achieve the seismic optimization process. The seismic collapse performance of the optimally designed steel chevron braced frames is assessed by performing incremen...

Sepsis is a systemic inflammatory response triggered by microbial infection that can cause cardiovascular collapse, insufficient tissue perfusion and multi-organ failure. The cation channel transient receptor potential vanilloid 4 (TRPV4) is expressed in vascular endothelium and causes vasodilatation, but excessive TRPV4 activation leads to profound hypotension and circulatory collapse key feat...

plan irregularity causes local damages being concentrated in the irregular buildings. progressive collapse is also the collapse of a large portion or whole building due to the local damages in the structure. the effect of irregularity on the progressive collapse potential of the buildings is investigated in this study. this is carried out by progressive collapse evaluation of the asymmetric mid...

Partial or complete recurrent lung collapse after cardiac surgery is one cause of failure to wean from ventilator support, and frequently leads to multiple reintubations and prolonging intensive care unit and hospital stays. A 79-year-old female underwent uneventful coronary artery bypass surgery and was extubated on the first postoperative day (POD). On POD 2, a routine portable chest X-ray (C...

The integrated assessment model FUND 2.8n is applied in an analysis of the overall economic consequences in a scenario of a shutdown of the thermohaline circulation (THC). Monetized market and non-market impacts of changes in environmental conditions following a THC collapse are determined for 207 individual countries. Eight different response patterns can be identified. The dominant pattern is...

This study aims at quantifying the influence on the traversability of road network of road network caused by building collapse in earthquake. To this end, an analysis method on post-earthquake traversability of road network considering building collapse is proposed. First, the time-history analysis of seismic response based on the multi-degree of freedom (MDOF) model is performed for regional b...
