Turbulent flow and heat transfer in outward transverse and helically corrugated tubes are performed with large eddy simulation by the ANSYS Fluent software. The prediction accuracy is validated by comparison with experimental data and empirical correlations for a wavy surface wall and smooth tube, respectively. The turbulent flow patterns, local heat transfer, and friction factor are discussed. Th

The compound Y 3 R u2−x was synthesized from the elements and the structure was solved from single crystal synchrotron data. The high quality of the data allowed the determination of the incommensurate ordering of the compound, previously reported as disordered, with respect to the second subsystem. The compound crystallizes in the super space group X-3(00γ)0 with the q-vector axial along c*, q

I ett intensivt relationsdrama blandas fakta med fiktion lika lättvindigt som nutida referenser blandas med historiska. Moraliska och existentiella frågor ställs kring, nation, krig, tro, idealism och pragmatism.

We report the dynamics of coflowing immiscible liquid streams exposed to an acoustic standing wave in a microchannel. Relocation of the liquid streams is experimentally demonstrated and a theoretical model that explains the underlying phenomena is presented. Our experiments and theoretical model suggest that the relocation phenomena are governed by the interplay between the primary acoustic radiat

Det är inte fråga om hur det kommer sluta. Vi vet redan hur det kommer sluta, vi känner till det slutet, "det våldsamma slutet, då hjärnan rinner ut efter upprepat våld mot skallbenet och likstelheten inträder". Det handlar inte om hur det slutar, har slutat, kommer sluta. Det är redan känt, det är redan skrivet, att "när de voro ute på marken överföll Kain sin broder Abel och dödade honom".

Background: The risk of dementia is increased in patients with atrial fibrillation (AF). Objective: To study relevant co-morbidities and incident dementia (vascular dementia, Alzheimers disease, other dementia and all dementia) in AF patients. Methods: All adults (n = 537,513) ≥45 years diagnosed with AF in hospitals in Sweden 1998–2012 were included. Cox regression was used to estimate hazard rat

AbstractPURPOSE: To assess the relative influence of genetic and environmental factors on optic disc size and cup/disc ratio in healthy eyes. METHODS: A sample of 55 monozygotic and 50 dizygotic healthy twin pairs aged 20-46, all having the same sex within pairs (47 pairs were male) had optic discs measured from colour fundus photographs according to the Wisconsin Protocol. Structural equation mod

In order to comprehensively understand the specific noise generation process inside pressure reducing valves (PRV) and its existing research outcomes, the generation of noise in PRV with its research methods in China and abroad was summarized. Then, the current research status of noise reduction technologies was reviewed from two aspects: source and propagation. Based on analysis and summarization

Konvergens är ett möte mellan en dramatiker och en kompositör i ett försök att bejaka likhet och skillnad i jakt på en (omöjlig) samstämmighet. Det är ett elektroakustiskt verk för en musiker, en sopran och två skådespelare. Det är ett försök att skapa platser för möte och krock. Mellan människor och mänskliga viljor, och mellan konstarter och dessas egna logiker. Frågor uppstår om ägande, känsla

The extent to which a favorable lifestyle may lower cancer risk in subjects with a family history of cancer is unknown. We conducted a prospective study in two Swedish cohorts, the Malmö Diet and Cancer Study (MDCS; n = 25,604) and the Malmö Preventive Project (MPP; n = 16,216). The association between a favorable lifestyle (based on nonsmoking, normal weight, absence of excessive drinking, regula

Several concurrent developments are shaping the future of plastics. A transition to a sustainable plastics system requires not only a shift to fossil-free feedstock and energy to produce the carbon-neutral building blocks for polymers used in plastics, but also a rational design of the polymers with both desired material properties for functionality and features facilitating their recyclability. B

The script we are presenting below is one of four different scenarios from Violence & Learning by Henrik Bromander and John Hanse, which was performed at the International Brecht Society’s Symposium in Oxford in June 2016. The learning play Violence & Learning has been developed and performed in the context of left-wing activism in Sweden. The different variants of the play have partly bee

Restricted numbers of substance P-like-immuno-reactive (SPL-IR) neurons were demonstrated in the photosensory pineal organ of the rainbow trout. The small parapineal organ of this teleost species receives a distinct SPL-IR innervation via the habenular nuclei, but displays no intrinsic SPL-IR neurons. Intrapineal SPL-IR neurons were located in the rostral portion of the pineal end-vesicle. Neurona

5-hydroxytryptamine (5-HT, serotonin)- and opsin-immunoreactive sites were studied in the developing pineal complex of the stickleback, Gasterosteus aculeatus L., by use of light-microscopic indirect immunoperoxidase techniques. 5-HT immunoreactivity first occurs in the pineal organ at the age of 80 h after fertilization and appears to be localized in cells of the photoreceptor type. The outer seg

The ontogenetic developments of the pineal organ, parapineal organ, and retina were studied by the use of light and electron microscopy in embryos and fry of the teleost, Gasterosteus aculeatus, from 60 to 168 h after fertilization. Sixty to 66 h after fertilization, the primordium of the pineal complex is discernible in the diencephalic roofplate; the parapineal anlage is located rostral to the p
