Further studies on the antigenic structure of paratyphoid bacilli with special reference to three new species of Salmonella

Three new species of Salmonella are described. 1. S. durban was obtained from an adult native woman suffering from dysentery. The antigenic formula allocated to it was IX-a, enx. 2. S. reading var. kaapstad was isolated from the cerebrospinal fluid of a child suffering from meningitis. Its antigenic structure was found to be IV-eh: 1, 7. 3. Two unrelated organisms were isolated from one of a group of pigs affected with paratyphoid. The one turned out to be S. heidelberg, factors IV, V-r: 1.2, while the other was found to be a new species with the following antigenic structure: XI- k: 1,2. The latter was named S. pretoria. 4. The biochemical reaction of these organisms are given in Table 1.The articles have been scanned in colour with a HP Scanjet 5590; 300dpi.

The barrel DIRC of PANDA

Cooled antiproton beams of unprecedented intensities in the momentum range of 1.5-15 GeV/c will be used for the PANDA experiment at FAIR to perform high precision experiments in the charmed quark sector. The PANDA detector will investigate antiproton annihilations with beams in the momentum range of 1.5 GeV/c to 15 GeV/c on a fixed target. An almost 4π acceptance double spectrometer is divided in a forward spectrometer and a target spectrometer. The charged particle identification in the latter is performed by ring imaging Cherenkov counters employing the DIRC principle

Experimental study of the Ni56(He3,d)Cu57 reaction in inverse kinematics

Measurements of (He3,d) reactions can provide information on the proton widths of states that play a role in astrophysically important (p,γ) reactions. We report on the first study of the (He3,d) reaction in inverse kinematics with a Ni56(T1/2=6.1 d) ion beam. The Q-value resolution of ~keV achieved in this experiment was sufficient to separate the transitions populating the ground state and the 1/2 - 5/2- doublet at Ex~1.1 MeV in Cu57. Prospects for similar (He3,d) experiments with improved energy resolution are also discussed

Ground-state band and deformation of the Z=102 isotope 254No

The ground-state band of the Z=102 isotope 254No has been identified up to spin 14, indicating that the nucleus is deformed. The deduced quadrupole deformation, β=0.27, is in agreement with theoretical predictions. These observations confirm that the shell-correction energy responsible for the stability of transfermium nuclei is partly derived from deformation. The survival of 254No up to spin 14 means that its fission barrier persists at least up to that spin

Orientation dependence in molecular dynamics simulations of shocked single crystals

The entry distribution in angular momentum and excitation energy for the formation of 254No has been measured after the 208Pb$48Ca,2n$ reaction at 215 and 219 MeV. This nucleus is populated up to spin 22h and excitation energy >˜6 MeV above the yrast line, with the half-maximum points of the energy distributions at ˜5 MeV for spins between 12h and 22h. This suggests that the fission barrier is >˜5 MeV and that the shell-correction energy persists to high spin
