The Measurement of Taxonomic Evenness in Zooarchaeology

open access: yesArchaeological and Anthropological Sciences, 2018
Zooarchaeologists frequently measure taxonomic evenness to document subsistence change and to understand the response of faunal communities to paleoenvironmental change.

Microchannel Plate Geometry Optimization for Even Flow Distribution at High Flow Rates

Chemical Engineering Research and Design, 2004
Microreactors generally consist of microstructured plates contg. a large no. of equal channels. The small diam. of the channels enables high heat and mass transfer rates. To exploit this feature and realize a high throughput within a small vol., it is necessary to use high flow rates.

Design of a mesh microreactor for even flow distribution and narrow residence time distribution

Chemical Engineering Journal, 2008
Abstract Flow and residence time distributions are analysed in a microreactor where the reactant fluid phases come into contact through the microfabricated pores of a mesh. An analytical resistance network method that is based on the analogy of viscous flow to networks of electrical resistances, initially developed to analyse flow distribution in ...

Experimental Study of Gas-Liquid Two-Phase Flow Even Distribution in Parallel-Flow Evaporator

Journal of Superconductivity and Novel Magnetism, 2010
An efficient parallel-flow evaporator has been applied to cryogenic equipment in recent years. The experiment studied the four different construction forms of parallel-flow evaporator in different conditions, the distribution of liquid flux in tubes, and observed the flow patterns.
