in the present work an attempt has been made to study the effect of the twisted tapes as bed internals, on the performance of the gas-solid fluidized beds. experimental investigation has been carried out in cylindrical column with and without twisted tapes. twelve numbers of twisted tapes of three different widths with four values of the twist ratios for each width were studied at different sta...

background: the aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age. materials and methods : twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angels were estimated by this algor...

We investigate the convergence rate of optimal entropic cost $$v_\varepsilon $$ to transport as noise parameter $$\varepsilon \downarrow 0$$ . show that for a large class functions c on $${\mathbb {R}}^d\times {\mathbb {R}}^d$$ (for which plans are not necessarily unique or induced by map) and compactly supported $$L^{\infty }$$ marginals, one has -v_0= \frac{d}{2} \varepsilon \log (1/\varepsil...

We investigate the low-lying zeros in families of L-functions attached to quadratic and cubic twists elliptic curves defined over Fq(T). In particular, we present precise expressions for expected values traces high powers Frobenius class these with a focus on lower order behavior. As an application obtain results one-level densities verify that curve have orthogonal symmetry type. twist our ref...

conclusions lv twist, torsion and untwist and also rate of them are significantly impaired in dcm and this impairment is well-related to lv global systolic and diastolic dysfunction. vvi is a new noninvasive technique that can be used to evaluate lv torsional parameters. results lv twist value (5.54 ± 1.94° in dcm vs. 11.5 ± 2.45° in control group) and also lv torsion (0.71 ± 0.28°/cm in dcm vs...

Abstract Estimation of the traditional transverse electric (TE) and magnetic (TM) impedances magnetotelluric tensor for two-dimensional structures can be decoupled from estimation strike direction with significant implications when dealing galvanic distortions. Distortion-free data are obtainable by combining a quadratic equation phase tensor. In terminology Groom–Bailey, provides amplitudes ph...

The transcription factor Twist plays vital roles during embryonic development through regulating/controlling cell migration. However, postnatally, in normal physiological settings, Twist is either not expressed or inactivated. Increasing evidence shows a strong correlation between Twist reactivation and both cancer progression and malignancy, where the transcriptional activities of Twist suppor...

Wnt1, initially identified as a mammary oncogene, can activate transcription via beta-catenin/TCF complexes. Twist, a transcription factor of the basic helix-loop-helix class, has also been suggested to have oncogenic properties. The aim of this study was to determine whether Twist is regulated by Wnt1 and might thus be a novel mediator of Wnt signaling. We found that Twist was up-regulated in ...
