The pullout resistance of reinforcement is an important parameter in the design reinforced retaining structures. At incipient failure, kinematics failure a structure shows that sliding mass soil pulls obliquely along slip surface. response to oblique pull can be considered made up equivalent axial and transverse components pull. Accordingly, tests were conducted on geostrip, metal strip (both s...

Rapidly-flowing ice streams are an important mechanism through which ice sheets lose mass, and much work has been focussed on elucidating the processes that increase or decrease their velocity. Recent work using standard inverse methods has inferred previously-unrecognised regular patterns of high basal shear stress (‘sticky spots’ >200 kPa) beneath a number of ice streams in Antarctica and Gre...

To characterize the histomorphologic effects of cadmium on adult newt testes, male Iberian ribbed newts (6 months post-hatching) were intraperitoneally exposed to a single dose of 50 mg/kg of cadmium, with histologic analysis of the testes at 24, 48, 72, and 96 h. Beginning 24 h after cadmium exposure, apoptosis of spermatogonia and spermatocytes was observed, and congestion was observed in the...

The present paper reports on the application of Principal Component Analysis (PCA) on the flow and thermal fields generated by the large-eddy simulation (LES) of a square ribbed duct heated by a constant heat flux applied over the bottom surface of the duct. PCA allows to understand the complexity of the resulting turbulent heat transfer process, identifying the flow and thermal quantities whic...

Abstract Laser Doppler anemometry (LDA) measurements in the fully developed turbulent flow through a one-sided rib-roughened square channel with rib-height-to-channel-height ratio of $$k/H = 0.0667$$ k / H = 0.0667 and ...

Stein, W.E. and Beck, C.B., 1992. New information on Bostonia pepTh'xa a n unusual member of the Calamopityaceae from North America. Rev. Palaeobot. Palynol., 72:73 102. A calamopityacean axis exhibiting multiple segments of primary xylem surrounded by secondary vascular tissue is analyzed here for its morphological and systematic significance. The plant is fundamentally protostelic with a deep...

The local structure, turbulence, and heat transfer in a flat ribbed duct during the evaporation of water droplets gas flow were studied numerically using Eulerian approach. structure turbulent two-phase underwent significant changes comparison with without ribs. maximum value gas-phase turbulence was obtained region downstream rib, it almost twice as high kinetic energy between Finely dispersed...
