In the present research, the laminar forced convective heat transfer and fluid flow characteristics for Al2O3-water nanofluid flowing in different bend (i.e., 180o and 90o) pipes have been investigated numerically in a three-dimensional computational domain using the finite volume technique. The effects of different pertinent parameters, such as the Reynolds number of the duct, volume fraction ...

Abstract We study universal sets of slopes for computing upward planar drawings st -graphs. first consider a subfamily -graphs, called bitonic prove that every set $$\mathcal {S}$$ S $$\varDelta $$ Δ containing the horizontal slope is 1-bend -graphs with maximum vertex degree , i.e., such dig...

Different flow-altering methods, such as W−Weirs, have been developed to reduce erosion. For this study, we performed two experiments: (1) installing a W−Weir in various positions determine the best angle for placement, and (2) investigating variation of flow patterns bed shear stress distribution 90-degree sharp bend by measuring 3D components velocities, with without where greatest scour dept...

We show that every graph of maximum degree three can be drawn without crossings in three dimensions with at most two bends per edge, and with 120◦ angles between all pairs of edge segments that meet at a vertex or a bend. We show that every graph of maximum degree four can be drawn in three dimensions with at most three bends per edge, and with 109.5◦ angles, i. e., the angular resolution of th...

Optical phased arrays (OPAs), the optical counterpart of at radio frequencies, can electronically steer an beam without any moving parts. To achieve a 180° field view (FOV), array emitters should be spaced half-wavelength apart or less. However, conventional OPA based on waveguide grating suffers from strong cross talk between adjacent waveguides when pitch is Here, we theoretically describe an...

We have used a circular permutation gel shift assay to show that the 5S gene transcription factor, TFIIIA, induces a bend at the internal promoter of the Xenopus oocyte-type 5S gene. The degree of bending is comparable to what we have previously observed for TFIIIA induced bending of the Xenopus somatic-type gene [Schroth, G.P. et al. (1989) Nature 340, 487-488]. In addition, we show that TFIII...
