FLUID FLOW MODELLING WITH FREE SURFACE
Barekeng, 2022 Fluid is a substance that can flow in the form of a liquid or a gas. Based on the movement of the fluid is divided into static and dynamic fluids. This study discusses fluid dynamics, namely modelling fluid flow accompanied by a free surface and an ...

Free Flow Electrophoresis of Chloroplasts [PDF]
Plant Physiology, 1978 Highly purified intact chloroplasts were isolated from spinach (Spinacia oleracea L.) leaves by free flow electrophoresis. Morphological and biochemical studies showed that the fraction enriched in intact chloroplasts has a higher protein to chlorophyll ratio and a higher linolenic acid content than the broken organelles of the other fraction.

Nonlinear Free Surface Flow past a Wedge in Channel [PDF]
INCAS Bulletin, 2023 In this paper, the two-dimensional problem of irrotational flow past a wedge located in the center of the channel is considered. Assuming that the fluid is incompressible and non-viscous, the influence of gravity is ignored but the surface tension is ...

Pushdown control-flow analysis for free [PDF]
Proceedings of the 43rd Annual ACM SIGPLAN-SIGACT Symposium on Principles of Programming Languages, 2016 Traditional control-flow analysis (CFA) for higher-order languages introduces spurious connections between callers and callees, and different invocations of a function may pollute each other's return flows. Recently, three distinct approaches have been published that provide perfect call-stack precision in a computable manner: CFA2, PDCFA, and AAC ...

Operator‐free flow injection analyser [PDF]
Journal of Analytical Methods in Chemistry, 1991 A flow injection analyser has been constructed to allow an operator‐free determination of up to 40 samples. Besides the usual FIA apparatus, the analyser includes a home‐made sample introduction device made with three electromechanical three‐way valves and an auto‐sampler from Technicon which has been adapted to be commanded by an external digital ...
