Lvi. Opsonins and Diets Deficient

ALTHOUGH it is well known that animals fed on diets deficient in vitamins frequently die from intercurrent bacterial infections, the reason for this apparent failure in the protective mechanism of the body is at present unknown. Hektoen [1914] found that the serum reactions were quite normal in animals fed for considerable periods on artificial diets, while later, Zilva [1919] could not determi...

On the Extremal Rays of the Cone of Positive, Positive Definite Functions

The aim of this paper is to investigate the cone of non-negative, radial, positivedefinite functions in the set of continuous functions on R. Elements of this cone admit a Choquet integral representation in terms of the extremals. The main feature of this article is to characterize some large classes of such extremals. In particular, we show that there many other extremals than the gaussians, t...

Lvi. the Relation between the Activity of Urease

A new LVI assisted PSFB DC-DC converter

In this study, a new Phase Shifted Full Bridge (PSFB) Pulse Width Modulated (PWM) isolated dc-dc converter is proposed. In the proposed converter, resonant inductor is replaced with Linear Variable Inductor (LVI) that is controlled by output current. The soft switching operation range is increased and the dependency of ZVS operation on the load current is decreased. The required energy for ZVS ...

Galactic cosmic rays & gamma rays : a synthesis

We have developed a model which aims to reproduce observational data of many kinds related to cosmic-ray origin and propagation: direct measurements of nuclei, antiprotons, electrons and positrons, γ-rays, and synchrotron radiation. Our main results include evaluation of diffusion/convection and reacceleration models, estimates of the halo size, calculations of the interstellar positron and ant...
