Relative 235 U(n,γ) and (n,f) cross sections from 235 U(d,pγ) and (d,pf) The internal surrogate ratio method allows for the determination of an unknown cross section, such as (n,γ), relative to a better-known cross section, such as (n,f), by measuring the relative exit-channel probabilities of a surrogate reaction that proceeds through the same compound nucleus. The validity of the internal sur...

The positive correlation between real (PPP) investment rates and levels of PPP income across countries is one of the most robust findings of the empirical growth literature. We show that this relationship is almost entirely driven by differences in the price of investment relative to output, rather than by differences in nominal investment rates. When measured in nominal terms (i.e., at nationa...

Background: CD1d presents glycolipid antigens to invariant natural killer T (iNKT) cells. The role of CD1d in the development of peptic ulcer and gastric cancer has not been revealed, yet. Objective: To clarify the expression of alternatively spliced variants of CD1d in peptic ulcer and gastric cancer. Methods: Patients with dyspepsia were selected and divided into three groups of non-ulcer dys...

let f, g and h be all entire functions of several complex variables. in this paper we would like to establish some inequalities on the basis of relative order and relative lower order of f with respect to g when the relative orders and relative lower orders of both f and g with respect to h are given.

sulphide was determined spectrophotometrically at 628 nm and ph 6.7 based on its catalytic reduction of toluidine blue in the presence of se(iv) using a flow injection system. after optimization of the measuring conditions the calibration curve was found linear up to 25 mg/ml and the detection limit was 0.3 mg/ml (30 ml injections). the relative standard deviation for the determination of 10 mg...

MNDO semi-empirical SCF MO calculations are used to study the pyramidal nitrogen atom inversion and configurational equilibria in the title compounds.

the composite diazotization coupling reaction of sulfanilic acid and n, ndimethylaniline was used for the precise, accurate, and rapid determination of trace amounts of nitrite ion (0.02-3 µg/ml). the reaction was monitored spectrophotometrically by measuring the absorbance of the produced methyl orange at 510 nm by a fixed the method of 5.0 minutes. the relative standard deviation for the dete...
