Counterflow isotachophoresis in a monolithic column
Journal of Separation Science, 2014This study describes stationary counterflow isotachophoresis (ITP) in a poly(acrylamide‐co‐N,N′‐methylenebisacrylamide) monolithic column as a means for improving ITP processing capacity and reducing dispersion. The flow profile in the monolith was predicted using COMSOL's Brinkman Equation application mode, which revealed that the flow profile was ...

The counterflow pipeline processor architecture
IEEE Design & Test of Computers, 1994The counterflow pipeline processor architecture (CFPP) is a proposal for a family of microarchitectures for RISC processors. The architecture derives its name from its fundamental feature, namely that instructions and results flow in opposite directions within a pipeline and interact as they pass.

Counterflow of galactosides in Escherichia coli
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1970Abstract Counterflow of β-galactosides in metabolically poisoned cells of Escherichia coli was systematically examined. In one type of experiment (“entrance counterflow”), azide-treated cells were preloaded with a galactoside, cells separated from the medium and finally resuspended in thio[ 14 C]methyl-β- d -galactopyranoside ([ 14 C]TMG).

Development of a swirling double counterflow
Physical Review E, 2011This numerical study of an axisymmetric motion of a viscous incompressible fluid in an elongated cylindrical container explains how a swirling inflow develops the global meridional circulation and two U-shaped throughflows (TFs). For moderate values of the Reynolds (Re) number, there is a single U-shaped TF: The fluid moves from the peripheral annular ...

Non-stalling counterflow architecture
Proceedings 1998 Fourth International Symposium on High-Performance Computer Architecture, 1998The counterflow pipeline concept was originated by Sproull et al.(1994) to demonstrate the concept of asynchronous circuits. This architecture relies on distributed decision making and localized clocking and data movement. We have taken these ideas and reformulated them into a substantially faster more scalable architecture that has the same ...

Enrichment of Corticotropes by Counterflow Centrifugation*
Endocrinology, 1988Anterior pituitary corticotropes represent only 9-10% of the mixed pituitary cell population. However, their small size precludes their enrichment because they cannot be separated from the more abundant PRL and GH cells. They can be induced to enlarge by adrenalectomy, and this report describes the separation of larger CRH-responsive corticotropes from

Development of colliding swirling counterflows
Physical Review E, 2011This numerical study of the axisymmetric motion of a viscous incompressible fluid in an elongated cylindrical container explains how colliding counterflows develop. Two swirling flows enter the container through peripheral inlets and leave it through central exhausts symmetrically from both ends.

This book discusses the physical mechanisms that drive counterflows, examining how they emerge, develop, become double and multiple counterflows and comprise both global and local circulations. Counterflows play an important role in nature and technology. A natural example is the Gulf Stream and the opposite flow in the ocean depths.

The counterflow transport of sterols and PI4P
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2016Cholesterol levels in intracellular membranes are constantly adjusted to match with specific organelle functions. Cholesterol is kept high in the plasma membrane (PM) because it is essential for its barrier function, while low levels are found in the endoplasmic reticulum (ER) where cholesterol mediates feedback control of its own synthesis by sterol ...

Counterflow spray combustion modeling
Combustion and Flame, 1989A fuel spray planar counterflow flame has been modeled by means of a low-Mach-number boundary layer approach. The model considers density variations and full coupling between the two phases by means of a hybrid Eulerian-Lagrangian formulation, with droplet drag and vaporization.
