The more/less concentrated designation is based on the ranking of the 1997 concentration ratio and choosing a break point that maximizes the marginal size of decreases in the concentration numbers in moving from more- to less-concentrated industries.
One of the unspoken issues in the United States is that we have more and more kids living in poverty (1 in 4 overall -- far more than any other industrialized country), and more and more schools catering to children in concentrated poverty (ratio of over 50% of children).
The raw sawdust was carbonized at 873 K in a nitrogen atmosphere, and concentrated H2SO4 was impregnated with carbonized materials in different concentrated H2SO4/sawdust ratios from 3 1 to 6 1 (w/w) at 575 K for 4 h.
The highly dispersed RuO2 nanoparticles can be obtained on carboxylated carbon nanotubes by preventing agglomeration among RuO2 nanoparticles through bond formation between the RuO2 and the surface carboxyl groups of the carbon nanotubes [92] or by treating the CNTs in a concentrated H2SO4/HNO3 (3:1 volume ratio) mixture at 70 °C [93].
As the particle volumetric concentration increases, the ratio of settling rates of concentrated slurry to a single particle settling decreases.
Moreover, the split ratio of concentrated stream has a deep effect on efficiency.
The orange attributes analyzed are total soluble solids, total titratable acidity, ratio, production, concentrated juice yield, and fruit size, which were performed in three periods (July, August and September).
The swirl flow microchannel heat sink showed promising cooling characteristics for applications such as thermal management of electronics or concentrated photovoltaics, with a ratio of pumping cost to heat rate of 0.02% for the base design studied.
Chloroauric acid solution was prepared by dissolving the Au wire (99.999 % in purity, Tanaka Kikinzoku Kogyo Co., Ltd). in a mixture of concentrated HNO3:HCl (volume ratio of 1 3).
Just before the experiment, the plate gold surface was purified by incubation in a mixture of "piranha" (a mixture of 30%H2O22 and concentrated H2SO4 in 1 3 ratio) for 2 min.
