Reliable accelerated simulation of asphalt aging is significant interest to researchers and pavement practitioners alike. However, current laboratory protocols are either based on binder rather than mixture or use dry ovens heat mixtures, omitting the important effects UV radiation. Binder cannot take into account interactions between aggregate phases during aging, while omission radiation igno...

Skid resistance and road condition are common indices of road safety; therefore providing adequate skidding resistance will reduce the incidence of road accidents. The surface macrotexture has a large effect on the characteristics of road surface skidding, which is the focus of this research. During the study, the mean texture depth of the road surface was measured, in order to determine the co...

The aim of this research work was to investigate on the ball filling estimation of Miduk semi-autogenous (SAG) Mill via an utilized method. Miduk copper concentrator is located in Kerman Province, Iran, and its size reduction stage includes one gyratory crusher which feeds one SAG mill (9.75 dia.(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). After SAG mill, a tromm...

Most cell growth media contain about 1 mg of choline per liter, consistent with concentrations usually employed for vitamins. One notable exception is the medium described by Waymouth (3) which contains 250 mg of choline per liter. For L cells growing in a chemically defined medium, I observed that increased choline permitted continuing growth of cells in the absence of medium replenishment ove...

Cold recycling of reclaimed asphalt (RA) is a promising technique to build or maintain roads, combining performance and environmental advantages. Although this has been extensively used worldwide, there no unique internationally-shared method characterize cold recycled mixtures. The previous work the RILEM TC 237-SIB TG6 successfully attempted different RA sources with both traditional paramete...

It is well known that the embryonic cells dissociated with the treatment of trypsin , when cultured on a gyratory shaker, tend to form a definite histoformative structure (Moscona 1961). The aggregation patterns, or the size, number, and shape of these cell aggregates, are characterized by the types and origins of the cells . These aggregates are formed through the cell-to-cell contacts which m...

Hearts from chick embryos aged 4,7, or 14 days were dissociated into their component cells, and the cells allowed to reassociate in the form of smooth-surfaced spheroidal aggregates on a gyratory shaker. Records from intracellular electrodes inserted into two widely spaced cells in a spontaneously beating aggregate indicated that the action potentials occurred virtually simultaneously. In aggre...
