Modeling of Sand and Crude Oil Flow in Horizontal Pipes during Crude Oil Transportation
Journal of Engineering, 2015 Some oil and gas reservoirs are often weakly consolidated making them liable to sand intrusion. During upstream petroleum production operations, crude oil and sand eroded from formation zones are often transported as a mixture through horizontal pipes up

Structural constraints on the subduction of mass-transport deposits in convergent margins [PDF]
Geological Society, London, Special Publications, 2020 Abstract The subduction of large and heterogeneous mass-transport deposits (MTDs) is discussed to modify the structure and physical state of the plate boundary and therewith exert an influence on seismicity in convergent margins. Understanding which subduction-zone architectures and structural boundary conditions favour the subduction of MTDs,

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Meso-Scale Kinematic Indicators in Exhumed Mass Transport Deposits: Definitions and Implications [PDF]
, 2016 In this study we combine observations and analytical data from large-scale (10-100s of m-thick and 100 m(2)-extensive), siliciclastic and carbonate MTD/MTCs belonging to the Oligocene - Miocene foredeep and wedge-top successions of the Northern Apennines and the Paleocene - Eocene Friuli basin of the northwestern Dinarides (Italy and Slovenia), to ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

3D seismic evidence of internal structure within Tampen Slide deposits on the North Sea Fan : are chaotic deposits that chaotic? [PDF]
, 2010 The seismic character of slide deposits is typically described as structureless or chaotic. However, 3D seismic data from the northern flank of the North Sea Fan reveal recognizable internal, penetrative structures within the Tampen Slide deposits.
