A high temperature retarder HTR-300L applied in long cementing interval
Petroleum Exploration and Development, 2013 With regard to slow development or super retarding happening at the top of cement slurry in deep and ultra-deep wells with long cementing intervals, a new type of retarder HTR-300L was developed and its properties were evaluated.

Thinning and thickening in active microrheology
, 2014 When pulling a probe particle in a many-particle system with fixed velocity, the probe's effective friction, defined as average pulling force over its velocity, $\gamma_{eff}:=\langle F_{ex}\rangle/u$, first keeps constant (linear response), then ...

Degenerate Solutions of General Relativity from Topological Field Theory [PDF]
, 1997 Working in the Palatini formalism, we describe a procedure for constructing degenerate solutions of general relativity on 4-manifold M from certain solutions of 2-dimensional BF theory on any framed surface Sigma embedded in M.

Egyptian Journal of Chest Disease and Tuberculosis, 2013 Background: The discrimination of pleural thickening from minimal pleural effusion may be difficult as both lesions appear as anechoic on grayscale ultrasound, hence, free of “echoes” does not confirm the presence of pleural fluid.

Investigations of Mixing Technique on the Rheological Properties of Self-Compacting Concrete
Applied Sciences, 2020 Rheological properties are of significant importance in successful placement and performance of self-compacting concrete (SCC). In this work, the rheological properties of SCC, combined with a powder-viscosity modifying admixture, were investigated based

Journal of Biomechanical Science and Engineering, 2015 Cellular and animal experiments and computational fluid dynamics (CFD) have revealed that mechanisms of the initiation, growth and rupture of a cerebral aneurysm are related to hemodynamics. By direct observation of a cerebral aneurysm during craniotomy,
