Recent developments in design criteria for granular and geotextile filters

Constriction Size of Geotextile Filters

Filtration performance of nonwoven geotextiles strongly depends on pore opening constriction size, i.e., the minimum opening size of flow channels across the geotextile. Currently available methods of pore opening characterizations do not provide accurate information about the constriction size. This paper presents the constriction size distributions of eleven nonwoven geotextiles commonly used...

Recent developments in configuration design and optimization of mineral separation circuits; A Review

The present research reviews two basic approaches for the separation circuit configuration analysis. The first approach is to optimize the circuit configuration. In this method, after a circuit modeling, a variety of search algorithms and mathematical optimization methods are used. Previous works show that this approach has more application in the flotation process. The second approach called t...

Mechanism Design: Recent Developments∗

Game theory provides methods to predict the outcome of a given game. Mechanism design concerns the reverse question: given some desirable outcome, can we design a game which produces it? Formally, the environment is hA,N,Θi , where A is a set of feasible and verifiable alternatives or outcomes, N = {1, ..., n} is a set of agents, and Θ is a set of possible states of the world. We focus on priva...

Phytoestrogens: recent developments

Phytoestrogens are polyphenolic non-steroidal plant compounds with estrogen like activity exerted through estrogen receptors. These receptors are distributed in several tissues such as male and female reproductive systems, bones, cardiovascular and central nervous systems. These natural phenolic compounds include isoflavonoids, flavonoids, lignans and stilbenes. Isoflavonoids are the most studi...
