This study investigated the combined effects of polyethylene terephthalate (PET) and crumb rubber (CR) as modifiers on some properties asphaltic concrete. Asphaltic concrete materials were obtained from a construction site. CR 9.5 mm size was by sieving, while PET bottles collected, sorted, washed, dried shredded mechanical means. The physical these determined following standard procedure. Bitu...

In order to effectively prevent and control the rutting problem of asphalt pavement in deep loess area Eastern Gansu reduce road diseases, diatomite was added into mixture for laboratory tests. Through Marshall test test, optimum mix proportion mixture, optimal amount this were determined. The performance activated SBS is compared analyzed through tests on-site paving. results show that under s...

Marshall sign and the doped t − J model Abstract Marshall sign as a sole source of sign problem hidden in an antiferromagnet is explored under doping. By tracking the Marshall sign, a zero spectral weight Z is revealed in the doped antiferromagnetic system. Z = 0 is caused by a phase string induced by the " bare " hole. By eliminating such a phase string through nonlocal transformations, a non-...

in petrochemical industry, the production of polyvinyl chloride (pvc) is accompanied by formation of heavy end wastes which consist of a mixture of di and multichloro compounds as kind of materials which are generated in ethylene dichloride (edc) purifcation. a high quantity of chloro compounds found in the heavy end waste allows it to be polymerized with alkaline polysulfdes to form polysulfde...

In this paper we discuss the problem on parametric and non parametric estimation of the distributions generated by the Marshall-Olkin copula. This copula comes from the Marshall-Olkin bivariate exponential distribution used in reliability analysis. Through this copula we can extend the Marshall-Olkin distribution in order to construct several bivariate survival functions. The cumulative distrib...

In this paper we consider the Marshall-Olkin bivariate Weibull distribution. The Marshall-Olkin bivariate Weibull distribution is a singular distribution, whose both the marginals are univariate Weibull distributions. This is a generalization of the Marshall-Olkin bivariate exponential distribution. The cumulative joint distribution of the Marshall-Olkin bivariate Weibull distribution is a mixt...

The new book, FLIES, tells us a lot about what gnats and their relatives have to tell us about nature, would we but listen attentively. The author, Stephen Marshall, began his biological interests in beetles and then somehow went to the dark side, FLIES. This reviewer began his career in beetles and stayed put; that is what qualifies him as a reviewer of this simply superb book Steve Marshall h...
