In order to study the stability of tunnels under static-dynamic load, a new large-scale model test system was developed. The composed static loading unit, dynamic data acquisition unit and bench, which were specially designed overcome technical problems test, such as control, high-rate strain measurement easy operation. used 3600 × 2500 mm in size larger load disturbance area than tests. It can...

BACKGROUND Retroviral-mediated gene transfer stably introduces exogenous genes into normal and neoplastic cells of the hematopoietic system. METHODS We used two retroviral vectors [the first, FLac, expresses a chimeric protein (Sh-ble::LacZ) between the product of the phleomycin resistance gene (Sh-ble) and the bacterial beta-galactosidase encoded by the LacZ gene; the second, NuNL vector, co...

Abstract In this essay, the progressive collapse resistance of reinforced concrete wall-frame structures was evaluated with and without considering soil–structure interaction. The vulnerability frames against investigated middle column removal scenario from first story, based on sensitivity index. To evaluate effects interaction, along soil (hard soil) foundation were simultaneously modeled in ...

In spite of the fact that the effect of earthquake on earth dams has been widely studied during the past decades, the complicated behavior of such earth structures against different seismological characteristics is still unknown. Such ambiguities necessitate more accurate studies using more comprehensive computation tools to achieve new results describing the behavior of such structures subject...

Back swing connections during gymnastics acrobatic series considerably influence technical performance and difficulties, particularly in the back somersault. The aim of this study was to compare the take-off's kinetic and kinematic variables between two acrobatic series leading to perform the backward stretched somersault (also called salto): round-off, flic-flac to stretched salto versus round...
