A new technique for identification of flow units of shaly sandstone reservoirs

Journal of Petroleum Exploration and Production Technology, 2017
The available techniques for identification of flow units of shaly sandstone reservoirs are based on different concepts, do not provide satisfactory results, and usually show discrepancy.

Systematic investigation of different formulations for drug delivery through the human nail plate "in vitro" [PDF]

, 2010
Human nails do not have only protective and decorative role, but can also be considered as an alternative pathway for drug delivery, especially in nail diseases such as onychomycosis or psoriasis.

Characteristics of Hydration Damage and Its Influence on Permeability of Lamellar Shale Oil Reservoirs in Ordos Basin

Geofluids, 2021
The continental shale oil reservoir has low permeability, high clay content, rich lamellar structure, and strong heterogeneity, which makes the reservoir vulnerable to hydration damage.

Construction of a carbonate reservoir model using transient pressure data

Petroleum Exploration and Development, 2009
A geological model is usually constructed using geophysical and petrophysical data by virtue of geological information. In this work, in order to achieving accurate model we built a carbonate reservoir model not only by seismic and well log data but also

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
