Mixture design of concrete using simplex centroid design ...

2018-5-1 · Obviously, the simplex centroid design method is a very powerful tool for the study of concrete. In this paper, an approach to optimize the mixture design of concrete based on rheological properties was proposed. To illustrate this method, the simplex centroid design method was first employed to analyze the effect of paste-fine aggregate-coarse ...

An Update of Wallace''s Zoogeographic Regions of the World

Biogeographic and bioclimatic regions are the fundamental units of comparison in many broad-scale ecological and evolutionary studies (1, 2) and provide an essential tool for conservation planning (3, 4) 1876, Alfred Russel Wallace published the first map of global terrestrial zoogeographic regions (), which later became the cornerstone of modern biogeography ().

Genesis Analysis of High-Gamma Ray Sandstone Reservoir …

In the Junggar basin, northwest China, many high gamma-ray (GR) sandstone reservoirs are found and routinely interpreted as mudstone non-reservoirs, with negative implications for the exploration and exploitation of oil and gas. Then, the high GR sandstone reservoirs'' recognition principles, genesis, and log evaluation techniques are systematically studied.

Determination of Tectonic Setting of Sandstone-Mudstone ...

2020-9-5 · Several previous studies have shown that sandstones from different tectonic settings possess characteristic chemistry, particularly content and ratio. Systematic variation of these variables with change in grain size in New Zealand greywackes shows that such discrimination can be extended to the finer-grained members (siltstones, mudstones) of sedimentary sequences.
