1 We develop the framework of natural spaces to study isomorphic embeddings of Banach spaces. We then use it to show that a sufficient failure of the generalized continuum hypothesis implies that the universality number of Banach spaces of a given density under a certain kind of positive embeddings (very positive embeddings), is high. An example of a very positive embedding is a positive onto e...

Recent results obtained by the COSY – 11 collaboration concerning the production of η and η mesons in the pp → ppMeson reaction are presented. A comparison of the production amplitude for the π, η and η mesons at the same phase space volume allows to conclude that the proton η interaction is in the order of, or smaller than, the proton-π one. A total cross section determined in a preliminary an...

This article provides a brief review of the history of the identification and characterization of the renal V-ATPase, and a review of the physiology of renal bicarbonate reabsorption and H + transport.

An ins t rument for determining the shape and in tens i ty distribut ion of particle and X-ray beams has been developed using an image intensifier tube together wi th a bundle of filaments of scintillator. A description of the use of such a device in high energy, low intensity, secondary meson and proton beams is given. I t is shown t h a t the sensi t ivi ty of th is instrumen t represents a s...

The fundamental reaction pp-->{pp}_{s}gamma, where {pp}_{s} is a proton pair with low excitation energy, has been observed with the ANKE spectrometer at COSY-Jülich for proton beam energies of T_{p}=0.353, 0.500, and 0.550 GeV. This is equivalent to photodisintegration of a free 1S0 diproton for photon energies E_{gamma} approximately T_{p}/2. The differential cross sections measured for c.m. a...

An ion-counting nanodosemeter (ND) yielding the distribution of radiation-induced ions in a low-pressure gas within a millimetric, wall-less sensitive volume (SV) was equipped with a silicon microstrip telescope that tracks the primary particles, allowing correlation of nanodosimetric data with particle position relative to the SV. The performance of this tracking ND was tested with a broad 250...

After more than 15 years, the operation of the world’s unique electron-proton collider HERA ended in June 2007. The data collected by the H1 experiment correspond to a total integrated luminosity of about 0.5 fb. In 2007 dedicated runs were taken at lower proton beam energies to measure the longitudinal proton structure function FL. In this talk new results, many of them exploiting data taken a...

Monte Carlo simulations play a crucial role for in-vivo treatment monitoring based on PET and prompt gamma imaging in proton and carbon-ion therapies. The accuracy of the nuclear fragmentation models implemented in these codes might affect the quality of the treatment verification. In this paper, we investigate the nuclear models implemented in GATE/Geant4 and FLUKA by comparing the angular and...
