Microfiltration (MF) and Ultrafiltration (UF) for Sewage and Surface Water Concentration for SARS‐CoV‐2 and Other Enveloped Viruses' Detection in Wastewater‐Based Epidemiology (WBE)

Biotechnology and Bioengineering, EarlyView.
ABSTRACT This study objective was to evaluate hollow fiber membranes for concentration of enveloped enteric viruses in sewage and surface water samples. Microfiltration (MF, 0.2 µm nominal pore size) and ultrafiltration (UF, 100 kDa molecular weight cut‐off) hollow fiber membranes were compared for the concentration of the bovine respiratory syncytial ...

Controls on fracturing in carbonate rocks

Proceedings of SPE Middle East Oil and Gas Show and Conference, 2005
Abstract Sedimentology (lithology, sedimentary structures, bed thick-ness, mechanical stratigraphy, the nature of bedding planes), structural geology (tectonic setting, palaeostresses, subsi-dence/uplift history, proximity to faults, position in a fold, timing of structural events, mineralisation, the angle between bedding and fractures)

Hydrogeology of carbonate rocks

1999
Carbonate rocks are sedimentary type of rocks containing more than 50% carbonate minerals which are mainly calcite, CaCO3, and dolomite, CaMg(CO3)2. The carbonate minerals could be a result of chemical precipitation, organic processes or may occur as detrital material.

Seismic velocities in carbonate rocks

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1991
Abstract Seismic velocities were measured in the laboratory vs pressure, temperature, and saturation on over 80 cores from various carbonate reservoirs in Alberta, using an ultrasonic pulse transmission method. Porosity, permeability, electrical properties, and capillary pressure were also measured in order to ...

Sequence stratigraphy of carbonate rocks

The Leading Edge, 1999
In the first contribution to TLE’s Geologic Column, J. M. Mulholland concluded that “sequence stratigraphy … is a tool that every explorationist must master.” I agree. In fact, sequence stratigraphy is more than a versatile tool in exploration and production geology. It is in many ways a role model for applied earth sciences.
