Effect of kaolin particle size and loading on the characteristics of kaolin ceramic support prepared via phase inversion technique

open access: yesJournal of Asian Ceramic Societies, 2016
In this study, low cost ceramic supports were prepared from kaolin via phase inversion technique with two kaolin particle sizes, which are 0.04–0.6 μm (denoted as type A) and 10–15 μm (denoted as type B), at different kaolin contents ranging from 14 to ...

Support sizes of triple systems

open access: yesJournal of Combinatorial Theory, Series A, 1992
The support size of a triple system \(\text{TS}(v,\lambda)\) of order \(v\) and index \(\lambda\) is the number of distinct triples. The set \(\text{SS}(v,\lambda)\) of possible support sizes in a \(\text{TS}(v,\lambda)\) is determined for all \(v\) and all \(\lambda\), except that it reamins undecided whether (1) \(s\in\text{SS}(14,6)\) for \(s=45,46 ...

Prediction of blasting mean fragment size using support vector regression combined with five optimization algorithms

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2021
The main purpose of blasting operation is to produce desired and optimum mean size rock fragments. Smaller or fine fragments cause the loss of ore during loading and transportation, whereas large or coarser fragments need to be further processed, which ...

Mass-mediated sex differences in climbing patterns support the gravity hypothesis of sexual size dimorphism [PDF]

open access: yesWeb Ecology, 2007
The gravity hypothesis of sexual size dimorphism can explain the patterns of extreme sexual size dimorphism in spiders (males smaller than females) because small males climb faster and therefore may be better at reaching females that live in high ...
