The main problem of reinforced flexible structures made cellular concrete is a rather low specific adhesion at the border reinforcement with concrete. This negatively affects pulling out from porous mass and leads to premature loss bearing capacity structure as whole. underestimation significant potential unused when using traditional provides for need improve approaches structures. Efficient p...

In June 1998, the Alpha magnetic spectrometer AMS [1] had a test flight on board space shuttle and recorded some 108 events. The AMS proton and leptons spectrum [2, 3] have a magnetic latitude dependence. The spectral shape of primary cosmic rays can be explained by the geomagnetic rigidity cutoff. However, below the rigidity cutoff, a second spectrum was clearly seen. The energy of this second...

Low back pain is a pain felt in the lumbar region of the spine. Among a large series of care strategies, lumbar belt might be used to treat this pathology. Several clinical trials have shown the efficiency of lumbar belts [1]. Despite the high quantity of affected patients each year (about 80 % of the French population have /will suffer back pain in their life), few authors investigated the mec...

Zonal centrifugation, based either on sediInentation rate or on isopycnic banding in liquid density gradients, is useful for high-resolution separation of subcellular particles. However, the amoun t of material which may be separated is extremely limited when conventional centrifuges are employed. To increase the capacity and, in certain instances, the resolution of the method, the possibility ...

Sufficient amounts of influenza virus (density, 1.185; size, 722S) can be highly purified (22,000 chicken cell agglutinating units per milligram of protein) with a zonal ultracentrifuge, used first in a rate process followed by isopycnic banding, to permit its detailed biological and physical-chemical evaluation.

Zonal flows are of keen interest in efforts to understand transport in magnetically confined plasma. Of the well-developed diagnostics, the Heavy Ion Beam Probe, HIBP, is most suited to measure the radial electric field, Er, associated with the flows in present medium to large devices. This paper discusses why the HIBP is capable of measuring Er and how to design an HIBP to optimize zonal flow ...

[1] Recent eddy-permitting simulations of the North Pacific Ocean have revealed robust patterns of multiple zonal jets that visually resemble the zonal jets on giant planets. We argue that this resemblance is more than just visual because the energy spectrum of the oceanic jets obeys a power law that fits spectra of zonal flows on the outer planets. Remarkably, even the non-dimensional proporti...

CO RR EC TE D PR OO Abstract The aim of this study is to classify the circulation patterns in the Atlantic-European sector and to reveal linkages between anomalies in the pressure field over the North Atlantic (e.g. North Atlantic Oscillation (NAO)) and its respective circulation pattern occurrence over continents on the one hand and rain fields on the other hand. Changes in atmospheric circula...

[1] We present an experimental and numerical study of a rotating fluid with a zonal flow produced from small-scale eddies, a common feature of many planetary systems. The apparatus consists of a water-filled annular tank with a sloped bottom. Flow is forced mechanically at small, nonaxisymmetric scales. Potential vorticity is materially conserved and well-mixed. This implies the existence of no...
