Reinforced concrete (RC) box girders are a common structural member for road bridges in modern construction. The hollow cross-section of a box girder is ideal in carrying eccentric loads or torques introduced by skew supports. This study employed acoustic emission (AE) monitoring on multicell RC box girder specimens subjected to laboratory-based torsion loading. Three multicell box girder speci...

Balanced regional cross sections based on surface, seismic, and subsurface data show that the thin-skinned fold-and-thrust belt in Rocky Mountain Foothills of Kakwa area central Canadian Rockies consists a lower buried thrust developed Paleozoic Triassic strata an upper exposed faulted fold Jurassic to Cretaceous strata. Changes wavelength, amplitude, geometry with stratigraphic level indicate ...

Photolysis is shown to be a major sink for isoprene-derived carbonyl nitrates, which constitute an important component of the total organic nitrate pool over vegetated areas. Empirical evidence from published laboratory studies on the absorption cross sections and photolysis rates of α-nitrooxy ketones suggests that the presence of the nitrate group (i) greatly enhances the absorption cross sec...

AIMS To determine whether alpha smooth muscle actin (alpha-SMA), a marker for myofibroblastic cells, is present in lens epithelial cells (LECs) in rabbit aphakic eyes. METHODS Phacoemulsification was performed in rabbit eyes, which were enucleated after surgery. Immunohistochemical methods were used to detect alpha-SMA in LECs. RESULTS Five days after surgery, the presence of alpha-SMA posi...

Different fields and disciplines in Science and Technology are imposing more stringent and accurate measurements of the proton and neutron total and differential cross-sections in the intermediate-energy range, from a few dozens of MeV up to a few GeV. Such measurements could be performed in facilities disposing of proton or light ion beams (namely facilities to produce Radioactive Nuclear Beam...

Background/Aim. C-shaped canals are a complex morphological variation of the tooth root canal system that, if present, could greatly affect outcome endodontic therapy. The prevalence these configurations varies between populations different ethnic and geographical origins. Therefore, goal this study was to analyze morphology mandibular second molar in population Central Serbia. Methods. include...

The problem of classifying dynamical systems (flows) with global cross-sections in terms of the associated diffeomorphisms of the crosssections is considered. Suppose that, for i = 1,2, ty is a C flow (r > 0) on the Cr manifold M¡ that admits a global cross-section 5, Q M¡ with associated diffeomorphism ('first return map') d¡. If rank (HX(MX ;Z)) = 1, then (Mx,<j)X) is Cs equivalent (s < r) to...

We treat hadron-hadron collisions where the final state is kinematically of the kind associated with double-pomeron-exchange (DPE) and has large transverse momentum jets. We show that in addition to the conventional factorized (FDPE) contribution, there is a non-factorized (NDPE) contribution which has no pomeron beam jet. Within a simple model we compute DPE-two-jet total and differential cros...
