Computational analysis of span-wise hole locations on fluid flow and film cooling of internal channels with crescent ribs

Purpose: This study aims to clarify the mechanism of film hole location at the span-wise direction of an internal cooling channel with crescent ribs on the adiabatic film cooling performance, three configurations are designed to observe the effects of the distance between the center of the ellipse and the side wall(Case 1, l = w/2, Case 2, l = w/3 and for Case 3, l = w/4). Design/methodology/appro

Magnetotransport properties of graphene layers decorated with colloid quantum dots

The hybrid graphene-quantum dot devices can potentially be used to tailor the electronic, optical, and chemical properties of graphene. Here, the low temperature electronic transport properties of bilayer graphene decorated with PbS colloid quantum dots (CQDs) have been investigated in the weak or strong magnetic fields. The presence of the CQDs introduces additional scattering potentials that alt

Resistance Through Acting : Ambivalent Practices of the No Border Musical

I ett Europa där gränskontroller intensifieras och deportationer ökar ställer denna avhandling frågor om möjligheter till motstånd och aktivism genom teater. Den tar sin utgångspunkt i en deltagande etnografisk undersökning av No Border Musical. No Border Musical skapades och sattes upp i Malmö under 2011–2013. Initiativet togs av personer kopplade till den lokala flyktingrättsrörelsen. Ungefär häIn a context of deportability and bordering practices, this thesis asks questions regarding possibilities and limitations of resistance through community theatre. It sets out from a participatory ethnographic exploration of the working process and performance of the No Border Musical. The No Border Musical was created in 2011–2013 in the city of Malmö in southern Sweden. It was initiated by people

Hospital differences in mortality rates after hip fracture surgery in Denmark

Background: Thirty-day mortality after hip fracture is widely used when ranking hospital performance, but the reliability of such hospital ranking is seldom calculated. We aimed to quantify the variation in 30-day mortality across hospitals and to determine the hospital general contextual effect for understanding patient differences in 30-day mortality risk. Methods: Patients aged ≥65 years with a

Reflecting a crisis reaction : Narratives from patients with oesophageal cancer about the first 6 months after diagnosis and surgery

Aim: The aim of the study was to describe patients' experiences of emotional adaption following treatment for oesophageal cancer from diagnosis to 6 months after surgery. Design: A qualitative interview study using an inductive approach was carried out. Methods: Participants were recruited from two university hospitals in Sweden. Ten patients who had been operated for oesophageal cancer with curat

Contribution of QCD condensates to the OPE of Green functions of chiral currents

A framework of operator product expansion (OPE) allows us to study high-energy behaviour of Green functions. A calculation of such Green functions within chiral perturbation theory (PT) or resonance chiral theory (RT) and subsequent matching of the result to the OPE enables us to determine constraints for unknown parameters of the effective theories. We present such procedure for Green functions i

Cardiac rehabilitation after acute myocardial infarction in Sweden – evaluation of programme characteristics and adherence to European guidelines : The Perfect Cardiac Rehabilitation (Perfect-CR) study

Background: While patient performance after participating in cardiac rehabilitation programmes after acute myocardial infarction is regularly reported through registry and survey data, information on cardiac rehabilitation programme characteristics is less well described. Aim: The aim of this study was to evaluate Swedish cardiac rehabilitation programme characteristics and adherence to European G

Power, efficiency and fluctuations in a quantum point contact as steady-state thermoelectric heat engine

The trade-off between large power output, high efficiency and small fluctuations in the operation of heat engines has recently received interest in the context of thermodynamic uncertainty relations (TURs). Here we provide a concrete illustration of this trade-off by theoretically investigating the operation of a quantum point contact (QPC) with an energy-dependent transmission function as a stead

Direct Electron-Transfer Anisotropy of a Site-Specifically Immobilized Cellobiose Dehydrogenase

To study the direct electron transfer (DET) of the multicofactor enzyme cellobiose dehydrogenase (CDH) in regard to its orientation on an electrode surface, a recently published, maleimide-based immobilization method was used in combination with site-directed mutagenesis to establish different orientations on an electrode surface. CDH from Myriococcum thermophilum was chosen for this study because

M&As in Africa – effects of law and governance

Purpose: The cultural and legal differences between foreign acquirers and African target firms can be substantial. There is also a large variation in cultures and legal systems within Africa. However, there is limited research on merger and acquisition (M&A) performance by foreign firms in Africa. The purpose of this paper is to fill this gap by exploring the “spillover by law” hypothesis (Mar

Hypotheses and tracking results about the longest migration : The case of the arctic tern

The arctic tern Sterna paradisaea completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack-ice zone. Salomonsen (1967, Biologiske Meddelelser, Copenhagen Danske Videnskabernes Selskab, 24, 1) put forward a hypothetical comprehensive interpretation of this global migratio

Establishing strong imputation performance of a denoising autoencoder in a wide range of missing data problems

Dealing with missing data in data analysis is inevitable. Although powerful imputation methods that address this problem exist, there is still much room for improvement. In this study, we examined single imputation based on deep autoencoders, motivated by the apparent success of deep learning to efficiently extract useful dataset features. We have developed a consistent framework for both training

Unexpected positive patch test reactions to sesquiterpene lactones in patients sensitized to the glucose sensor FreeStyle Libre

Background: Most diabetic patients sensitized to FreeStyle Libre react to isobornyl acrylate (IBOA), with a considerable number of them also showing unexpected positive patch test reactions to sesquiterpene lactone (SL) mix (SLM) tested in the baseline series. Objectives: To compile patch test results of subjects affected, and provide potential explanations for this association. Patients and Metho

Patient registries for home oxygen research and evaluation

Randomized clinical trials are the preferred study design to address key research questions about the benefits or harms of interventions. However, randomized trials of oxygen therapy are difficult to conduct and have limitations. The purpose of this article is to offer our view on the potential use of patient registries in the field of home oxygen in COPD as an alternative to randomized trials by

A Recommender System for User-Specific Vulnerability Scoring

With the inclusion of external software components in their software, vendors also need to identify and evaluate vulnerabilities in the components they use. A growing number of external components makes this process more time-consuming, as vendors need to evaluate the severity and applicability of published vulnerabilities. The CVSS score is used to rank the severity of a vulnerability, but in its

Women in Stem Cell Science: Part I

Female scientists play important leadership roles in the field and with the International Society for Stem Cell Research. We asked a number of these top researchers to share their personal stories and reflect on their career paths. Part II of this series will run in the October 2018 issue of Stem Cell Reports.

Burden of Atopic Dermatitis in Swedish Adults : A Population-based Study

The burden of atopic dermatitis (AD) was assessed. A population-based, cross-sectional questionnaire study was performed among 34,313 Swedish adults in 2017. The prevalence of AD was 14%. Adults with mild AD had an increased relative risk ratio (RRR) of severe depression (aRRR 1.78, 95% confidence interval (95% CI) 1.50–2.12) and anxiety (aRRR 1.97, 95% CI 1.69–2.30), which was higher for severe A
