Marine environment is a harsh and challenging for both operators analysers due to extreme weather conditions. As result of these conditions, marine structures are subjected and/or cyclic loadings. This will then lead various different damage modes including corrosion fatigue. Such major threats the reliability integrity which can cause risk on human environmental safety, yield financial losses....

Atmospheric dust loadings play a crucial role in the global climate system. Southern South America is a key dust source, however, dust deposition rates remain poorly quantified since the last glacial termination (~17 kyr ago), an important timeframe to anticipate future climate changes. Here we use isotope and element geochemistry in a peat archive from Tierra del Fuego, to reconstruct atmosphe...

Wind effects on tensile fabric structures (TFS) are not extensively investigated. Available studies consider simplified TFS support conditions and comparisons between static dynamic analyses lacking. The response of a double hypar under varying wind speed is carried out by using fluid-structure interaction (FSI). Realistic considered. geometry determined through form-finding. Computational flui...

background:  this  study  aimed  to  prospectively  analyze  the  effect  of  a  major  earthquake on the prevalence of psychological disorders such as acute stress disorder (asd), anxiety, depression,  mixed  anxiety  depression  disorder  (madd),  phobia,  aggressive  behavior, insomnia, psychosomatic disorders and also sociodemographic aspects among residents of rural community sample in eas...

The accumulation of phosphorus (P) and metals is a serious concern with the continuous application of manure to agricultural soils. Solid-liquid separation of swine slurry is a promising approach to reduce P and metal loadings through application of separated liquid (SL) as a nutrient source. However, little information is available on nutrient and metal loadings with the application of SL comp...

Arch dams are designed for the same loads as other dams with the exception of the temperature load, which has a significant influence in arch dam design as compared to gravity dam design. In concrete arch dams, because of the particular geometry, solar radiation shares of exposed surfaces vary spatially through downstream face. In this case, threedimensional temperature distribution analysis is...

We probe the reliability of monopile support structures designed to support industrial scale turbines along the coastal United States using stochastic models for the wind and wave loadings, and representations of the uncertainty associated with soil properties. The turbine support structure investigated is that promulgated by the National Renewable Energy Laboratory as typical of a monopile sup...

Dynamic soaring of a sailplane in the earth’s atmospheric boundary layer was computationally investigated over a range of conditions to explore the feasibility of flying over a large vertical extent over open fields. A point-mass sailplane model was studied as well as a full six degree-of-freedom (6-DOF) piloted sailplane model. For the point-mass model, parameter sweeps were performed around a...
