Coprecipitation of 14C and Sr with carbonate precipitates: The importance of reaction kinetics and recrystallization pathways
Abstract This study investigated the simultaneous removal of Sr2+ and 14CO3 2− from pH>12 Ca(OH)2 solution by the precipitation of calcium carbonate. Initial Ca2+:CO3 2− ratios ranged from 10:1 to 10:100...

Subsurface Drainage and Storage Properties in the Western Ghats – A Study in the Basin of Netravati
Abstract One of the reasons for the highly subdued response of the catchments, even to rainfalls of very high daily intensity, in the wet tropical areas of the Western Ghats in Karnataka is their soil mantle, which is very thick, well drained and...

Laboratory Measurements of Fluid Transport Properties on Tight Gas Sandstones and Applications
Abstract Deep gas reservoirs are of great interest for the E&P industry. Large areas of such reservoirs have permeabilities below 1 mD. The reservoir rocks in these areas show a strong stress sensitivity of the fluid transport properties and a...

Simulation of Asteroid Impact on Ocean Surfaces, Subsequent Wave Generation and the Effect on US Shorelines
Abstract As part of a larger effort involving members of several other organizations, we have conducted numerical simulations in support of emergency-response exercises of postulated asteroid ocean impacts. We have addressed the problem from source...

Seasonal and spatial patterns of SST in the northern Arabian Sea during 2001–2012
Abstract Ocean–atmosphere interactions have been increasingly acknowledged to play an important role in climate change. It is necessary to understand ocean behavior, including the sea surface temperature (SST) that is a basis for initiating...

Modelling Aeolian Erosion in Presence of Vegetation
Abstract Soil erosion by wind has many environmental, climatic and health implications. Dust storm represents one of the most dramatic events related to soil erosion. The possible increase of drought events due to climate change may accentuate the...

Detailed Petrophysical and Geophysical Characterization of Core Samples from the Potential Caprock-reservoir System in the Sulcis Coal Basin (Southwestern Sardinia – Italy)
Abstract In this work we present a methodology suitable to identify a caprock-reservoir system for the CO2 storage in the Sulcis Coal Basin (SW Sardinia – Italy). The petrophysical and geophysical characterizations indicate that the potential...

Process intensification and integration of solar heat generation in the Chinese condiment sector – A case study of a medium sized Beijing based factory
Abstract Over the last decade, energy prices in China have risen dramatically. At the same time, extensive use of coal fired energy provision systems in industry has led to serious environmental and economic problems translating to an economic...

Effects of land use and management on aggregate stability and hydraulic conductivity of soils within River Njoro Watershed in Kenya
Abstract There has been tremendous changes in land use and management in the River Njoro Watershed during the last three decades. Formerly large scale farms have been converted into smallholder farms and plantation forests have gradually been lost....

CFD modelling of a tidal stream turbine subjected to profiled flow and surface gravity waves
Abstract This study used computational fluid dynamics to investigate the effect of waves and a velocity profile on the performance of a tidal stream turbine (TST). A full scale TST was transiently modelled operating near its maximum power point, and ...

Injection and Monitoring at the Wallula Basalt Pilot Project
Abstract Continental flood basalts represent one of the largest geologic structures on earth but have received comparatively little attention for geologic storage of CO2. Flood basalt lava flows have flow tops that are porous, permeable, and have...
