Measurement of endwall heat transfer around a circular cylinder with a vortex generator pair has been investigated. Steady state liquid crystal thermography is adopted. Cylinders having two different height to diameter ratios have been employed. In one case, the cylinder has one end free in the flow and in the other case it has both ends attached on the walls. Local Nusselt numbers both upstream a
Previous research has proved Double-layer Microchannel Heat Sinks (MHSs) to be efficient ways to improve the cooling performance of electronic devices. However, the cooling potential of the upper working liquid cannot be fully utilized to cool down the substrate with the heated elements. In this sense, a concept of staggered double-layer MHS is proposed and designed. The parallel and counter flow
In most industrial product development projects, computer-based design analysis, or simply design analysis, is frequently utilized. Several design analysis process models exist in the literature for the planning, execution and follow-up of such design analysis tasks. Most of these process models deal explicitly with design analysis tasks within two specific contexts: the context of design evaluati
Thermal uniformity in the flow field plate of proton exchange membrane fuel cells (PEMFCs) is crucial for their power generating efficiency and reliability and therefore, has attracted much attention. The present numerical study is an attempt to optimize the flow channels via replacement of convectional zigzag continuous channels by tree-like bifurcated channels radially outwards. The numerical mo
Aim: To report basic epidemiological data concerning surgically treated childhood cataract in Sweden and Denmark. Methods: Data were derived from the Paediatric Cataract Register (PECARE), a binational, web-based surgical register representing Sweden and Denmark. All children operated before 8 years of age between 1 January 2007 and 31 December 2013 were included. Age-specific prevalence per 100 0
The rock-cut chamber tombs form a very small percentage of the rockcut tombs in Labraunda. The majority of these tombs, situated next to the sanctuary, were studied by Paul Åström in 1950 together with the sarcophagi; two improved from natural caves further from the sanctuary in both directions were found in a topographic survey conducted by Lars Karlsson in 2005, and finally one tomb at some dist
Background. Lowe syndrome (LS) and Dent-2 disease (DD2) are disorders associated with mutations in the OCRL gene and characterized by progressive chronic kidney disease (CKD). Here, we aimed to investigate the long-term renal outcome and identify potential determinants of CKD and its progression in children with these tubulopathies. Methods. Retrospective analyses were conducted of clinical and ge
Acute myeloid leukemia (AML) remains the most common form of acute leukemia among adults and accounts for a large number of leukemia-related deaths. Mutations in FMS-like tyrosine kinase 3 (FLT3) is one of the most prevalent findings in this heterogeneous disease. The major types of mutations in FLT3 can be categorized as internal tandem duplications (ITD) and point mutations. Recent studies sugge
Delayed-return foraging strategies connected with a sedentary lifestyle are known from Late Mesolithic Scandinavian settlements. However, recent evidence from the archaeological site of Norje Sunnansund, in south-eastern Sweden, indicates the presence of sedentism from the Early Mesolithic. By analyzing the faunal assemblage from Norje Sunnansund, patterns of delayed-return strategies were examine
Den österrikiske författaren och essäisten Robert Musil förser sociologin med väsentliga reflektioner och problemställningar. Musil för fram diskussioner som överskrider konventionella förståelser av moderniteten – sociologins generella analysobjekt. Artikeln fokuserar på två grundläggande kluster av frågor och begrepp i Musils arbete: människans gestaltlöshet och förhållandet mellan förnuft och kThe writings of the Austrian novelist and essayist Robert Musil provide sociology with vital problems and reflections. Indeed, Musil introduces discussions that extend conventional understanding of modernity – sociology’s general object of analysis. The article focuses on two major sets of questions in Musil’s work: the shapelessness of man and the relation between reason and sentiments. Both prob
Purpose To describe a large cohort of femtosecond laser–assisted cataract surgeries in terms of baseline characteristics and the related outcomes. Setting Eighteen cataract surgery clinics in 9 European countries and Australia. Design Prospective multicenter case series. Methods Data on consecutive eyes having femtosecond laser–assisted cataract surgery in the participating clinics were entered in
The parasitoid wasp Nasonia vitripennis is an emerging genetic model for functional analysis of DNA methylation. Here, we characterize genome-wide methylation at a base-pair resolution, and compare these results to gene expression across five developmental stages and to methylation patterns reported in other insects. An accurate assessment of DNA methylation across the genome is accomplished using
This paper explores the potential success of the so called sharing economy, focusing on power relations and social practices, emotions and cultural meanings of lending and borrowing as a way of stretching existing urban ecologies.
