effective elastic properties for carbon nanotube reinforced composites are obtained through a variety of micromechanics techniques. an embedded carbon nanotube  in  a  polymer  matrix  and  its surrounding  interphase  is  replaced with an equivalent fiber for  predicting  the  mechanical  properties of  the  carbon  nanotube/polymer composite. the effects of an interphase layer between the nan...

We present experimental and simulation results for focused ion beam (FIB) milling of microchannels in lithium niobate in this paper. We investigate two different cuts of lithium niobate, Y- and Z-cuts, and observe that the experimental material removal rate in the FIB for both Y-cut and Z-cut samples was 0.3 μm(3)/nC, roughly two times greater than the material removal rate previously reported ...

The aspect ratio (Γ) dependence of the heat transfer (Nusselt number Nu in dimensionless form) in turbulent (two-dimensional) Rayleigh-Bénard convection is numerically studied in the regime 0.4≤Γ≤1.25 for Rayleigh numbers 10(7)≤Ra≤Ra(9) and Prandtl numbers Pr=0.7 (gas) and 4.3 (water). Nu(Γ) shows a very rich structure with sudden jumps and sharp transitions. We connect these structures to the ...

UNLABELLED We used DOG ellipses and outlined ellipses that contained, respectively, only low-frequency and only high-frequency information about aspect ratio. Cross-adaptation (i.e., adapt DOG/test outline and adapt outline/test DOG) produced aspect ratio aftereffects. CONCLUSION Spatial information encoded in terms of the body of the stimulus and in terms of the boundary of the stimulus have...

Flow past a disk was investigated experimentally in a low-velocity water channel in the range of intermediate Reynolds numbers. Systematic experiments with flow visualization and particle image velocimetry measurements are presented. Different disks with the aspect ratio χ = d/h varying from 1 to 24 were investigated. The measurements were made in the range of Reynolds numbers from 0 to 500, wh...

Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...

background: patients with graves’ disease exhibit a considerable rate of relapse after treatment with antithyroid drugs and require ablative therapy.   objective: the purpose of this study was to evaluate variables which can be used as prognostic factors in predicting the outcome of graves’ disease after treatment with antithyroid drugs.   methods: age, sex, duration of antithyroid drug therapy...
