since individuals spend the majority of their times indoors, fine particles generated in indoor combustion processes and by resuspension are important for health effects assessment. the nature and magnitude of indoor particle exposures can change rapidly because of the rapid changes in activities and sources. indoor pm 2.5 concentrations were measured in indoor office, café, and home where peop...

this study deals with bioleaching of the low grade uranium ore of saghand mine in iran using a mixed culture of mesophilic bacteria (acidithiobacillus ferrooxidans, acidithiobacillus thiooxidans and leptospirillum ferrooxidans). experiments were carried out in shaking flask examining the effect of temperature, initial ferrous ion concentration, pulp density and particle size. variations of ph, ...

The vast majority of current research on hydrocyclone field centrifugal separation focuses low concentration fluids having volume fraction less than 3%. For high-concentration fractions greater 10%, which are often encountered in engineering, the law governing particle motion and classification mechanism still unclear. In order to gain insights into interaction between fine particles high impro...

In this paper, we consider graphon particle systems with heterogeneous mean-field type interactions and the associated finite approximations. Under suitable growth (resp. convexity) assumptions, obtain uniform-in-time concentration estimates, over infinite) time horizon, for Wasserstein distance between empirical measure its limit, extending work of Bolley–Guillin–Villani (2007).

We sought to partition the genetic and environmental influences on lipoprotein subclasses and identify genomic regions that may harbor genetic variants that influence serum lipoprotein levels in a sample of Gullah-speaking African-Americans. We genotyped 5,974 SNPs in 979 subjects from 418 pedigrees and used the variance component approach to compute heritability estimates, genetic and environm...

a study of the kinetic analysis of total lead from spent car battery ash by hydrochloric acidleaching has been examined. the physico-chemical analysis of the ash powder was carried outby the inductively coupled plasma-mass spectrometry (icp-ms) and x–ray diffraction (xrd).the effects of the acid concentration, temperature and particle size on the rate of battery ashdissolution have been investi...
