Crosswell attenuation tomography is used to image reservoir zones that were flooded by carbon dioxide. The swept zones contain mixtures of oil, water and carbon dioxide. Monitoring the saturation of these fluids is an important part of a enhanced oil recovery process. We estimate the changes in P-wave attenuation caused by the injection process. Laboratory data on flooded cores are analyzed in ...

This paper presents the algorithms that CERTH team deployed in order to tackle disaster recognition tasks and more specifically Disaster Image Retrieval from Social Media (DIRSM) and FloodDetection in Satellite images (FDSI). Visual and textual analysis, as well as late fusion of their similarity scores, were deployed in social media images, while color analysis in the RGB and nearinfrared chan...

Decomposition of red oak acorns (Quercus spp.; Section Erythrobalanus) could decrease forage biomass and gross energy (GE) available to wintering ducks from acorns. We estimated changes in mass and GE for 3 species of red oak acorns in flooded and non-flooded bottomland hardwood forests in Mississippi during winter 2009–2010. Mass loss of acorns was 8.1% and reduction in GE 0.03 kcal/g after ex...

Background/introduction Unilateral lung flooding replaces air with saline in lung parenchyma. It has been shown, that in flooded condition ultrasound guidance and HIFU ablation of central lung cancer tissue is feasible. The flooding process generates a saline-lung compound which is different than known parenchymal tissue. Complete understanding of the flooding process is essential for its imple...

population-based survey randomly selected the hamlet of Tunku. The survey team waded across flooded paddy fields, constantly asking for directions. Tunku turned out to be a cluster of five mud huts perched on a hill on the bank of the River Gambia. The team found two families and one blind old woman there. The villagers could only reach their homes from the river using dugout canoes, and they g...

This study presents an approach for modelling and mapping fluvial flooding, considering both land use/land cover (LULC) change climate change, applies it to the Brahmani River Basin in eastern India. Climate projections were obtained from Coupled Model Intercomparison Project Phase 6 (CMIP6), their impacts on hydrology of catchment investigated using HEC-HMS HEC-RAS software. Results reveal tha...

Availability of wetlands with low salinities during the breeding season can influence waterfowl reproductive success and population recruitment. Salinities as 2 ppt (3.6 mScm–1) impair duckling growth behavior, mortality occurring above 9 (14.8 mScm–1). We used satellite imagery to quantify amount available water, sampled surface water salinity at Grizzly Island, in brackish Suisun Marsh, three...

A model for the simulation of the steady-state impedance response of a polymer electrolyte membrane fuel cell ~PEMFC! cathode is presented. The catalyst layer of the electrode is assumed to consist of many flooded spherical agglomerate particles surrounded by a small volume fraction of gas pores. Stefan-Maxwell equations are used to describe the multicomponent gas-phase transport occurring in b...

The municipality of Minaçu, in the northern region state Goiás, differs from many Brazilian municipalities due to intense changes that have occurred its territory. is known as capital asbestos, an ore gave rise occupation region, whose extraction has lasted six decades. In addition large pits opened by mining, also two hydroelectric plants, part their respective reservoirs, which occupy a land....
