Glutathion no sangue humano normal

1.) - Woodward-Fry's and Okuda-Hess technics were employed in the determination of blood glutathione in normal healthy adults of both sexes. 2.) - It was found more accurately results with the technic of Woodward and Fry than of any others for the dosage of G. S. H. of blood. 3.) - When the process of Okuda-Hess is modified by the use of an intern indicator (starch) the readings of the end-point are much more easy and therefore the results more exacts. 4.) - The averages of the data obtained for normal blood by the technic of Woodward and Fry were for men per hundred cubic cent. 27 mgrs (G.S.H); 6.6 mgrs. (G.S.S) and 33.6 mges. (G. T) and for women: 28.4 mgrs. (G.S.H), 7.8 mgrs. (G.S.S) and 36,2 mgrs. (G.T). 5.) - Autoxidation in the blood filtrate is only apreciated after 24 hs. In the first eight hours autoxidation is never observed. 6.) - The increase of glutathione in hyperglobulia is a function of the amount of red corpuscles. In acrocyanosis arterial blood is richest in these component than venous blood and this fact is in accordance with the observation of Blanchetière, Mélon and Binet for the experimental asphyxia of dogs.

Single period Markowitz portfolio selection, performance gauging and duality: a variation on Luenberger's shortage function

Markowitz portfolio theory (1952) has induced research into the efficiency of portfolio management. This paper studies existing nonparametric efficiency measurement approaches for single period portfolio selection from a theoretical perspective and generalises currently used efficiency measures into the full mean-variance space. Therefore, we introduce the efficiency improvement possibility function (a variation on the shortage function), study its axiomatic properties in the context of Markowitz efficient frontier, and establish a link to the indirect mean-variance utility function. This framework allows distinguishing between portfolio efficiency and allocative efficiency. Furthermore, it permits retrieving information about the revealed risk aversion of investors. The efficiency improvement possibility function thus provides a more general framework for gauging the efficiency of portfolio management using nonparametric frontier envelopment methods based on quadratic optimisation.

The third order Melnikov function of a quadratic center under quadratic perturbation

We study quadratic perturbations of the integrable system (1+x)dH; where H =(x²+y²)=2: We prove that the first three Melnikov functions associated to the perturbed system give rise at most to three limit cycles.
