Heat transfer correlations for jet impingement boiling over micro-pin-finned surface

Heat transfer performance of submerged jet impingement boiling over staggered micro-pin-finned surfaces was investigated using air-dissolved FC-72. The dimension of the silicon chips is 10 × 10 × 0.5 mm3 (length × width × thickness) on staggered micro-pin-fins with four dimensions of 30 × 30 × 60 μm3, 50 × 50 × 60 μm3, 30 × 30 × 120 μm3 and 50 × 50 × 120 μm3 (width × thickness × height, named S-PF

Smoking, disease characteristics and serum cytokine levels in patients with primary Sjögren's syndrome

Smoking affects several disease processes. Epidemiological studies have previously found a negative association between primary Sjögren's syndrome (pSS) and smoking. The aim of this study was to examine whether markers of disease activity and cytokine expression in pSS patients differ between ever and never smokers. Fifty-one consecutive pSS patients and 33 population controls were included in the

Brandskyddsvärdering av flerbostadshus BSV-FB : Utveckling av metod för säkerhetsindex

A fire safety assessment method for multi-family buildings has been developed. The method is a scoring method and 19 parameters are assessed in order to determine the building fire safety level. Each parameter has its own weight for the total fire safety and the parameter weights are determined based on judgement in two expert groups. The expert groups have performed the weighting assessment indep

Prevalence of G6PD deficiency and associated haematological parameters in children from Botswana

Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is commonly seen in malaria endemic areas as it is known to confer a selective advantage against malaria. Recently, we reported a high proportion of asymptomatic reservoir of Plasmodium vivax in Botswana, that calls for intervention with primaquine to achieve radical cure of vivax malaria. Considering that individuals with this enzyme deficiency

Localized carbon deposition in solid oxide electrolysis cells studied by multiphysics modeling

Solid oxide electrochemical cells (SOCs) can store electrical energy in the form of chemical fuels with high efficiency by electrolysis of CO2 and H2O. However, achieving commercially relevant lifetime is hindered by degradation mechanisms such as carbon deposition, which can even destroy the cell especially during electrolysis where carbon formation is electrochemically driven at the electrode-el

Is familial risk for depression confounded by individual and familial socioeconomic factors and neighborhood environmental factors? A 7-year follow-up study in Sweden

Family history of depression is an important risk factor for depression. The aim of this study was to examine whether the effect of family history of depression is confounded by individual and familial socioeconomic factors (i.e., country of origin, educational attainment, family income and mobility) and neighborhood environmental factors (i.e., neighborhood deprivation and neighborhood social cap

Formation of NO and NH in NH3-doped CH4 + N2 + O2 flame : Experiments and modelling

Co-combustion of 5200 ppm NH3 with a stoichiometric, atmospheric pressure, CH4 + N2 + O2 flame has been investigated with experiments and kinetic modelling. Profiles of the amidogen (NH) radical and nitric oxide (NO) have been measured using laser-induced fluorescence, the latter being quantitatively determined. Temperature profiles were measured using Rayleigh scattering and thermocouple, the non

Binge eating and other eating-related problems in adolescents undergoing gastric bypass : results from a Swedish nationwide study (AMOS)

Bariatric surgery is established as a treatment option for adolescents with severe obesity. Little is known about binge eating (BE) and other eating-related problems in adolescents undergoing bariatric surgery. BE, emotional eating, uncontrolled eating, and cognitive restraint were assessed at baseline, and one and two years after gastric bypass using questionnaires in 82 adolescents (mean age 16.

Developing defined substrates for stem cell culture and differentiation

Over the past few decades, a variety of different reagents for stem cell maintenance and differentiation have been commercialized. These reagents share a common goal in facilitating the manufacture of products suitable for cell therapy while reducing the amount of non-defined components. Lessons from developmental biology have identified signalling molecules that can guide the differentiation proc

Mortality and causes of death among people who inject amphetamine : A long-term follow-up cohort study from a needle exchange program in Sweden

Background: Abuse of amphetamines is a worldwide problem with around 34 million users, and amphetamine is commonly used by people who inject drugs (PWID). Despite this, there is relatively little research on mortality and cause of death among people who use amphetamines primarily. The present study aimed to examine mortality and causes of death among people who inject amphetamine, and compare thes

Dabigatran, rivaroxaban and apixaban vs. high TTR warfarin in atrial fibrillation

Introduction: New oral anticoagulants are non-inferior compared with warfarin regarding stroke prevention in atrial fibrillation, with similar or decreased risk of bleeding. However, it is unclear whether high TTR warfarin is as effective and safe as NOACs. Our objective was to investigate efficacy and safety of apixaban, dabigatran or rivaroxaban compared with warfarin in clinical practice. Mater

Chernobyl as the Beginning of the End of the Soviet Union

The belief in technology was fundamental in Soviet culture. When the nuclear reactor exploded and harvested souls and spread illness throughout a vast area, over the course of many years, an image of the collapse of the Soviet Union was thereby created. Chernobyl became an image of the apocalypse of communism

Self-reported nonsuicidal self-injury (NSSI) and sex as self-injury (SASI) : Relationship to abuse, risk behaviors, trauma symptoms, self-esteem and attachment

This study focuses on a conceptually unexplored behavior among adolescents who report deliberately using sex as a means of self-injury. In a large high school-based sample (n = 5743), adolescents who engaged in sex as self-injury (SASI, n = 43) were compared to adolescents who reported direct nonsuicidal self-injury (NSSI, n = 933) and those who reported both NSSI and SASI (n = 82). Results showed

A Western dietary pattern is prospectively associated with cardio-metabolic traits and incidence of the metabolic syndrome

The aim of this study was to derive dietary patterns associated with cardio-metabolic traits and to examine whether these predict prospective changes in these traits and incidence of the metabolic syndrome (iMetS). Subjects from the Malmö Diet and Cancer Study cardiovascular cohort without cardio-metabolic disease and related drug treatments at baseline (n 4071; aged 45-67 years, 40 % men) were in

The combined effects of FADS gene variation and dietary fats in obesity-related traits in a population from the far north of Sweden : the GLACIER Study

Background: Recent analyses in Greenlandic Inuit identified six genetic polymorphisms (rs74771917, rs3168072, rs12577276, rs7115739, rs174602 and rs174570) in the fatty acid desaturase gene cluster (FADS1-FADS2-FADS3) that are associated with multiple metabolic and anthropometric traits. Our objectives were to systematically assess whether dietary polyunsaturated fatty acid (PUFA) intake modifies

Acute inflammatory biomarker responses to diffuse traumatic brain injury in the rat monitored by a novel microdialysis technique

Neuroinflammation is a major contributor to the progressive brain injury process induced by traumatic brain injury (TBI), and may play an important role in the pathophysiology of axonal injury. The immediate neuroinflammatory cascade cannot be characterized in the human setting. Therefore, we used the midline fluid percussion injury model of diffuse TBI in rats and a novel microdialysis (MD) metho

Constructing Authority in Times of Crisis : A Genre Analysis of Government Crisis Communication in China

Purpose: This study investigates how the Chinese government generates authority during a crisis through discursive practices expressed in social media. Design/methodology/approach: Using the theoretical framework of authority and the method of genre analysis, this study examined the top 100 forwarded posts on Weibo about a highprofile murder to determine the mechanisms involved in generating autho
