Based on the analysis of the mechanism and hazards of asphalt fume, by adding two fume suppressant Mg(OH)2 and Al(OH)3 and two viscosity reducers Sasobit and ROADBIT-BPL, the paper optimized the mixture ratio for road use, and prepared the environment-friendly fume-suppression asphalt, and then conducted the performance tests to identify the optimum dosage. The results show that: the fume amoun...

Self-Compacting concrete (SCC) needs no external vibration and compacts fully under its self weight. This paper describes experimental work carried out to develop SCC and to study the effect of different sizes (i.e., 20mm; 16mm; 12.5mm and 10mm) of coarse aggregate (C.A) on the properties of SCC. Eight mixes were investigated for M30 grade concrete. The water-powder ratio was kept fixed through...

The Ashkenazi Jewish (AJ) population is important in genetics due to its high rate of Mendelian disorders. AJ appeared in Europe in the 10th century, and their ancestry is thought to comprise European (EU) and Middle-Eastern (ME) components. However, both the time and place of admixture are subject to debate. Here, we attempt to characterize the AJ admixture history using a careful application ...

A variety of estimators have been developed to use genetic marker information in inferring the admixture proportions (parental contributions) of a hybrid population. The majority of these estimators used allele frequency data, ignored molecular information that is available in markers such as microsatellites and DNA sequences, and assumed that mutations are absent since the admixture event. As ...

Recent human-machine interaction studies have suggested that movement augmented with negative viscosity can enhance performance and can even promote better motor learning. To test this, we investigated how negative viscosity influences motor adaptation to an environment where forces acted only in one axis of motion. Using a force-feedback device, subjects performed free exploratory movements wi...

Guar gum can be used to effectively improve stability and mobility of microscale zerovalent iron particles (MZVI) used in groundwater remediation. Guar gum is a food-grade, environment friendly natural polysaccharide, which is often used as thickening agent in a broad range of food, pharmaceutical and industrial applications. Guar gum solutions are non-Newtonian, shear thinning fluids, characte...

Oceanic uptake and long-term storage of atmospheric carbon dioxide (CO2) are strongly driven by the marine “biological pump,” i.e., sinking of biotically fixed inorganic carbon and nutrients from the surface into the deep ocean (Sarmiento and Bender, 1994; Volk and Hoffert, 1985). Sinking velocity of marine particles depends on seawater viscosity, which is strongly controlled by temperature (Sh...

Hispanics in the U.S. Southwest have genetic ancestry from Europeans and from American Indians, two groups with markedly different breast cancer incidence rates. Genetic admixture may therefore bias estimates of associations between candidate cancer susceptibility genes and breast cancer in Hispanics. We estimated genetic admixture using 15 ancestry-informative markers for 1,239 Hispanics and 2...
