We investigate the acceleration and simultaneous radiative losses of electrons in the vicinity of relativistic shocks. Particles undergo pitch angle diffusion, gaining energy as they cross the shock by the Fermi mechanism and also emitting synchrotron radiation in the ambient magnetic field. A semi-analytic approach is developed which allows us to consider the behaviour of the shape of the spec...

Background. Superior cut-out of a lag screw remains a serious complication in the treatment of trochanteric or subtrochanteric fractures and it is related to many factors: the type of fracture, osteoporosis and the stability of fracture reduction. Little is known about the outcome after revision surgery for complications of the gamma nail. We assessed the outcome in patients who had revision su...

Optic morphology (Om) mutations in Drosophila ananassae map to at least 22 loci scattered throughout the genome. They are semidominant, neomorphic, nonpleiotropic, and are associated with the insertion of a retrotransposon, tom. The Om(1A) gene, which is cytogenetically linked to the cut locus, was cloned using a DNA fragment of the cut locus of Drosophila melanogaster as a probe. Three of the ...

The reaction $\gamma p \rightarrow \pi^0 \eta$ has been studied with the CBELSA/TAPS detector at electron stretcher accelerator ELSA in Bonn for incident photon energies from threshold up to 3.1 GeV. This paper motivated by recently claimed observation of a narrow structure M$_{N\eta}$ invariant mass distribution 1678 MeV/$c^2$. existence this cannot be confirmed present work. Instead, E$_{\gam...

Determining if the SM-like Higgs is part of an extended sector most important question to be asked after discovery. A light charged boson with mass smaller than sum top and bottom quarks naturally allowed in Type-I two doublet model can produced association neutral scalars for large parts parameter space at LHC. Such low typically have dominant decays fermionic modes viz. $\tau\nu$ $c s$. Howev...

OBJECTIVE In vitro interferon-gamma (IFN-gamma) assays have emerged as novel alternatives to the tuberculin skin test (TST) for the diagnosis of latent tuberculosis (TB) infection. These assays have been evaluated in low incidence countries, mainly in adults, and have been shown to be more specific than TST. Because few studies have been done in high incidence countries, and because paediatric ...
