P1 Modeling sepsis using neural nets and biomarkers of organ dysfunction in patients, with links to animal models Background: Most clinical trials of sepsis treatment modalities fail at their primary objective of establishing superiority over placebo when added to background standard of care. While there is no definitive explanation for the high failure rate, it might be stated that our attempt...

Shock tolerance is desirable for ceramic particles-reinforced metal matrix composites in many applications, where the dislocation dynamics evolution under extreme load key but still elusive. Herein, we have investigated motion and interaction shock loading of SiC/Al nanocomposites using molecular simulations. We demonstrated that plastic deformation occurs at an impact velocity (0.5 km/s) lower...

conclusions this study suggests that obese patients in hs may have a higher risk of hemodynamic instability compared to their nonobese counterparts primarily due to obesity-induced increases in intra-abdominal pressure resulting in reduced venous return. results in hemorrhage simulation, moderate increases in bmi were found to produce greater decreases in map and co compared to the normal subje...

This paper studies a reliability modeling for $k$ -out-of- notation="LaTeX">$n$ : notation="LaTeX">$F$ load sharing system that operates in shock environment. Such consists of protective device and components with sharing. The base ha...

Typically, to study the effects of consecutive earthquakes, it is necessary to consider definite intensity levels of the first shock. Methods commonly used to define intensity involve scaling the first shock to a specified maximum interstorey drift. In this study the structure’s predefined elastic spectral acceleration caused by the first shock is also considered for scaling. This study aims to...

When the buried pipeline is subjected to external explosion load, stress and deformation will occur. value exceed a specific range, it affect normal use of pipeline. In this paper, multiphase coupled model pipeline, soil fluid within established. The penalty function coupling method used describe load between By specifying boundary conditions system, global solution variational principle soil-p...

The tunnel lining segments are assumed to be rigid, and the tensile, compression, shear, bending properties of joints considered. A simplified calculation method for dynamic response structure under ground shock is proposed, its correctness verified by comparing it with results from finite element method. Using this method, a subway calculated, change in joint force studied, influence angle bet...

results we performed rush on 77 patients. kappa index was 0.71 (p value = 0.000), reflecting acceptable general agreement between initial impression and final diagnosis. for hypovolemic, cardiogenic and obstructive shock, the protocol had an npv above 97% yet it had a lower ppv. for shock with distributive or mixed etiology, rush showed a ppv of 100% but it had low sensitivity. subgroup analysi...

conclusions hepatic shock is detected in ill patients, especially those with hemodynamic disorders. it can be prevented by early treatment of underlying disease. there is no definite treatment for hepatic shock and should be managed conservatively. hepatic shock in patients can increase the mortality rate. results different causes can lead to hepatic shock. most of these causes can be prevented...

Background: Heat-shock proteins are part of a strictly controlled biological system that allows organisms to respond to environmental stresses. Different proinflammatory cytokines are present in the synovial tissue of rheumatoid arthritis patients. Such tissues respond to stress and induce heat-shock proteins. In addition, synovial cells are exposed to mechanical stress caused by joint motion. ...
