The purpose of toroidal flow, i.e., strike-slip motion and plate spin, in the plate-tectonic style of mantle convection is enigmatic. It is a purely horizontal, dissipative flow field that makes no apparent contribution to the release of heat. However, when plate-like toroidal motion is allowed to arise as a phenomenon of non-Newtonian mantle dynamics, it in fact acts to reduce the net amount o...

Introduction. Waveguides have been successfully used to generate magnetic resonance images at 7 Tesla for whole-body systems [1]. From these results, it has been established that waveguides are only suitable for 7T systems with wide bores of al least 60 cm. This is mainly due to the cut-off frequency of the cylindrical waveguides used. To overcome this limitation a parallel-plate waveguide was ...

The nonlinear interaction of waves in a driven medium may lead to wave turbulence, a state such that energy is transferred from large to small length scales. Here, wave turbulence is observed in experiments on a vibrating plate. The frequency power spectra of the normal velocity of the plate may be rescaled on a single curve, with power-law behaviors that are incompatible with the weak turbulen...

Introduction Leaf of areca tree (Areca catechu L.) is a hard material (good tensile strength), slow in biodegradation and has low calorific value. About 1000 million leaf sheaths (2,33,000 tonnes) are available annually in India alone. Areca leaf sheath (cellulose, 43%) by digestion using sulphite process at 162°C for 3.5 h gives a pulp (yield, 36-40%), which in admixture with other pulp can be...

drop plate technique has a priority and preference compared with the spread plate procedure, because of less time, quantity of media, effort requirement, little incubator space, and less labor intensive. the objective of this research was to compare the accuracy and fidelity of drop plate method vs. spread plate method by parametric and nonparametric statistical tests. for bacterial enumeration...

[1] We analyze the role of slab pull acting on the Pacific plate during its early Tertiary change in motion. Slab pull forces are estimated by integrating the negative buoyancy of a 700 km long slab along a revised subduction boundary model adopting the Müller et al. (2008) seafloor age reconstructions. Our results indicate that torques predicted from a simple slab pull model match the Pacific ...

Long-term use of glucocorticoids (GC) can cause growth retardation in children due to their actions on growth plate chondrocytes. AL-438, a non-steroidal anti-inflammatory agent that acts through the glucocorticoid receptor (GR) retains full anti-inflammatory efficacy but has reduced negative effects on osteoblasts compared to those elicited by prednisolone (Pred) or dexamethasone (Dex). We hav...
