this paper describes the effects of reinforcement by randomly distributed nylon fibers and addition of nanoclay on some engineering properties of a typical asphalt concrete. the properties of asphalt concrete reinforced by different percentages of 25 mm nylon fibers have been compared with those of the mixtures containing different percentages of nanoclay and those in which both the fibers and ...

local anesthetic solutions are frequently mixed to take advantage of the useful properties of each drug but the medical literature is surprisingly deficient in well controlled studies about the onset and duration of action of these mixtures for epidural anesthesia. a total of 32 patients scheduled for elective operation were enrolled in this prospective randomized controlled study; in group i, ...

The static and dynamic properties of binary mixtures of hard spheres with a diameter ratio of sigma(B)/sigma(A)=0.1 and a mass ratio of m(B)/m(A)=0.001 are investigated using event driven molecular dynamics. The contact values of the pair correlation functions are found to compare favorably with recently proposed theoretical expressions. The transport coefficients of the mixture, determined fro...

in recent years, it has become increasingly important to incorporate explicit dynamics in economic analysis. these two tools that mathematicians have developed, differential equations and optimal control theory, are probably the most basic for economists to analyze dynamic problems. in this paper i will consider the linear differential equations on the plane (phase diagram) and elements of nonl...

social and political culture can be conceived as a trend consisting of ethical rules as its stractur, scientific thought as its process and dynamic knowledge of facts as its agenda elhical rules are intedecd to solve structural problems, scientific that is aimed at gaining knowledge corresponding with the facts, and the agenenda is not affaring truth but reliable and dynamic knowledge of the fa...

This paper concentrates on the reflection of plane waves in the mixture of generalized thermo elastic solid half-space. There exists quasi dilatational waves i.e. qP1, qP2, qT and two rotational waves S1, S2 in a two dimensional model of the solid. The boundary conditions are solved to obtain a system of five non-homogeneous equations for amplitude ratios. These amplitude ratios are found to de...
