A novel control of jet impingement heat transfer in cross-flow by a vortex generator pair

Jet impingement is an effective heat transfer method while the favorable performance is usually degraded by the cross-flow. In this article, a novel control of the impinging jet in cross-flow has been proposed. A delta winglet vortex generator pair (VGP) is installed in the cross-flow channel upstream of the jet nozzle. The jet and the cross-flow Reynolds numbers are 15,000 and 40,000, respectivel

The Tenseless Copula in Temporal Predication

In this paper I explore how the tenseless copula is to be interpreted in sentences of the form “a is F at t”, where “a” denotes a persisting, changeable object, “F” stands for a prima facie intrinsic property and “t” for a B-time. I argue that the interpretation of the copula depends on the logical role assigned to the time clause. Having rejected the idea that the time clause is to be treated as

Rearrangements of chromosome bands 15q12-q21 are secondary to HMGA2 deregulation in conventional lipoma.

Rearrangements of chromosome arm 15q are rare but recurrent in conventional lipomas, a tumor type often showing deregulated expression of the HMGA2 gene. In order to assess whether 15q rearrangements could constitute a distinct pathogenetic mechanism, we studied seven cases of conventional lipoma that at G-banding analysis had various rearrangements of 15q12-q21. The breakpoints in 15q were mapped

Lim Domain Binding 2: A Key Driver of Transendothelial Migration of Leukocytes and Atherosclerosis.

Using a multitissue, genome-wide gene expression approach, we recently identified a gene module linked to the extent of human atherosclerosis. This atherosclerosis module was enriched with inherited risk for coronary and carotid artery disease (CAD) and overlapped with genes in the transendothelial migration of leukocyte (TEML) pathway. Among the atherosclerosis module genes, the transcription cof

DNMT3A moderates cognitive decline in subjects with mild cognitive impairment: replicated evidence from two mild cognitive impairment cohorts.

Epigenetic dysregulation has been associated with cognitive decline and Alzheimer's disease. The present study investigated associations between common SNPs in genes regulating DNA methylation and age-related changes in cognitive decline in two independent prospective cohorts of patients suffering from mild cognitive impairment. An association between the rs1187120 SNP in DNMT3A and annual decline

Interaction between an incompressible flow and elastic cantilevers of circular cross-section

The purpose of this work is to study the deformation of elastic cantilevers due to hydrodynamic forces by coupled fluid-structure interaction simulations. The cantilever is placed in a rectangular duct and the Reynolds number based on bulk velocity and cantilever diameter is 400. Reduced velocities in the range pi/4 to 2 pi are studied, which covers both un-synchronised motion and the initial bran

When the Butcher Calls the Hunter Foul, and the Muddied Politics which Follow: Speciesism and the EU Opposition to the Wolf Hunt

Rarely does the death of animals cause conflict between governments. However, the killing of some animals, such as seals, wolves, and other exotic wildlife, can cause heated conflict over whether the act of killing is itself justifiable.This paper provides an overview of a recent disagreement along these lines – between the EU and Sweden over the management of wolves. It juxtaposes the recent poli

Fitting-Attitude Analyses: The Dual-Reason Analysis Revisited

Classical fitting-attitude analyses understand value in terms of its being fitting, or more generally, there being a reason to favour the bearer of value. Recently such analyses have been interpreted as referring to two reason-notions rather than to only one. The idea is that the properties of the object provide reason not only for a certain kind of favouring(s) vis-à-vis the object, but the very

High-energy breakfast with low-energy dinner decreases overall daily hyperglycaemia in type 2 diabetic patients: a randomised clinical trial

Aims/hypothesis High-energy breakfast and reduced-energy dinner (Bdiet) significantly reduces postprandial glycaemia in obese non-diabetic individuals. Our objective was to test whether this meal schedule reduces postprandial hyperglycaemia (PPHG) in patients with type 2 diabetes by enhancing incretin and insulin levels when compared with high-energy dinner and reduced-energy breakfast (Ddiet). Me

Order-Disorder Transition of Nonionic Onions under Shear Flow

We have investigated the shear-induced ordering of multilamellar vesicles (onions) in a nonionic surfactant (C12E4) system using a small-angle light scattering (shear-SALS) and a small-angle X-ray scattering (shear-SAXS) technique. In a narrow shear rate-temperature space, the onions form a two-dimensional (2D) hexagonally close-packed structure that shows characteristic hexagonal scattering patte

A re-examination of the Fisher effect using an alternative approach

The Fisher Effect (FE) is of fundamental importance in financial markets. The majority of previous studies have not managed to obtain the expected one-for-one reaction of the nominal interest rate to the inflation rate. The aim of this article is to reinvestigate the FE for the USA and the UK using a case-wise bootstrap approach developed by Hatemi-J and Hacker (2005). This method is robust to non

Anchored LH2 Complexes in 2D Polarization Imaging.

Protein is a soft material with inherently large structural disorder. Consequently, the bulk spectroscopies of photosynthetic pigment protein complexes provide averaged information where many details are lost. Here we report spectroscopy of single light-harvesting complexes where fluorescence excitation and detection polarizations are both independently rotated. Two samples of peripheral antenna (

Identification of signal bias in the variable flip angle method by linear display of the algebraic Ernst equation

A novel linear parameterization for the variable flip angle method for longitudinal relaxation time T1 quantification from spoiled steady state MRI is derived from the half angle tangent transform, t, of the flip angle. Plotting the signal S at coordinates x=St and y=S/t, respectively, establishes a line that renders signal amplitude and relaxation term separately as y-intercept and slope. This re
