an attempt has been made in this paper to investigate the effect of particle size distribution on coal flotation kinetics. the effect of particle size (ps) on kinetics constant (k) and maximum theoretical flotation recovery (ri) was investigated while other operational parameters were kept constant. the relationship between flotation kinetics constant and theoretical flotation recovery with par...

background: little is known about the influence of habitual participation in physical exercise and diet on upper-extremity physical function in older adults. to assess the relationship of general physical exercise and diet to upper-extremity physical function and pain intensity in older adults.   methods: a cohort of 111 patients 50 or older completed a sociodemographic survey, the rapid assess...
