"We started offering DC plan services to small businesses, recognizing that this segment of the market was underserved and overcharged," Crystal Hardie Langston, Vanguard principal and head of VRPA, said in a statement.
Almost all the plans VRPA administers have a designated default investment option, usually a target-date fund.
"As a result, nearly 80% of VRPA participants hold a balanced portfolio."
VRPA and boundary layer thickness presented above are design parameters of photoreactors and their calculations require a model of radiant field, which quantify LVRPA within the reactor.
The SFM parameters were calculated to the experimental conditions reported (<[I.sub.0]>) [approximately equal to] = 1.81 x [10.sup.-8] Einstein [cm.sup.-2] [s.sup.-1], catalyst Aldrich, <[sigma]> = 3.60 x [10.sup.4] [cm.sup.2] [g.sup.-1], and ([kappa]) = 3.28 x [10.sup.3] [cm.sup.2] [g.sup.-1]) with a local percent error of LVRPA lower than 12, and 2.4 for VRPA.
The catalyst Aldrich has a maximum VRPA 7% higher than the one presented by the catalyst Degussa.
For all catalysts and loadings lower than 0.1 g/l, the absorption of photons occurs in the entire thickness of the reactor (1 cm), but the VRPA has small values.
A point above this curve presents a dark layer inside reactor, while a point below it presents VRPA less than the maximum possible.
