On the improvement of film cooling performance using tree-shaped network holes : A comparative study

For modern high-efficiency gas turbines, film cooling is an essential method to protect the turbine blade from the hot gas, and the issue about how to improve the film cooling performance has attracted much attention. This study presents a new design concept used for film cooling in gas turbine to improve the overall cooling effectiveness and better decrease the metal temperature of the blade at t

Brett samhällsfokus krävs för att förstå hälsoojämlikheter - Hälso- och sjukvården bara ett av många områden som inverkar för att uppnå målet om jämlik hälsa

The understanding of health inequalities requires further development of epidemiological capacity and must have a broad focus on social determinants of health The article by Agardh et al (1) in this issue of Läkartidningen compares the trend of population health in Stockholm county versus the rest of the country. The article represents an important attempt to monitor and understand the driving for

Demographic factors in the choice of coronal restoration after root canal treatment in the Swedish adult population

Background: After root canal treatment, a choice is made between different coronal restorations which in the long run could affect the survival of the tooth. Objective: To compare demographic characteristics between individuals choosing an indirect coronal restoration (crown, inlay/onlay) and individuals choosing other restorations after completion of a root filling. Methods: The cohort consisted

Hospitalization rate of paroxysmal supraventricular tachycardia in Sweden

Introduction: The hospitalization rate of paroxysmal supraventricular tachycardia (PSVT) in a nationwide study is not established. We determined age- and sex-specific hospitalization rates and time trends for hospitalized PSVT in the Swedish population between 1987 and 2010. Methods: This nationwide study is based on the Swedish Hospital Discharge Register. The patients with first PSVT diagnoses b

"Rädsla snedvrider politisk debatt"

Personer som bryr sig om vad andra tycker om dem håller sig borta från diskussioner om politik i sociala medier, trots att de är intresserade av politik. Politiska diskussioner i sociala medier och webbaserade paneler kan därför vara en snedvriden avbild av vad människor i allmänhet egentligen tycker och tänker, skriver forskare med utgångspunkt i en ny studie.

3D printing technology in musical instrument research : reviewing the potential

Purpose: This paper aims to discuss additive manufacturing (AM) in the context of applications for musical instruments. It examines the main AM technologies used in musical instruments, goes through a history of musical applications of AM and raises the questions about the application of AM to create completely new wind instruments that would be impossible to produce with conventional manufacturin

ICU-recovery in Scandinavia : a comparative study of intensive care follow-up in Denmark, Norway and Sweden

OBJECTIVES: The aim of our study was to describe and compare models of intensive care follow-up in Denmark, Norway and Sweden to help inform clinicians regarding the establishment and continuation of ICU aftercare programmes.METHODS: Our study had a multi-centre comparative qualitative design with triangulation of sources, methods and investigators. We combined prospective data from semi-structure

Refinancing Risk and Debt Maturity Choice during a Financial Crisis

This paper explores whether refinancing risk is an important determinant of maturity decisions by investigating how firms with refinancing risk choose the maturity of new loans they obtain during the 2007-2009 financial crisis. The firms' refinancing risk is measured by the maturing portion of outstanding long-term debt. The result shows that firms with a high refinancing risk choose longer maturi

Prediction of Acute Postoperative Pain from Assessment of Pain Associated With Venous Cannulation

Background: It has previously been reported that venous cannulation-induced pain (VCP) can be used to predict acute postoperative pain after laparoscopic cholecystectomy. Patients rating VCP at ≥2.0 VAS units had 3.4 times higher risk for moderate or severe pain. The purpose of this study was to evaluate if VCP scores of ≥2.0 VAS units are associated with higher risk for acute postoperative pain a

Problems with reliability of speech variables for use in quality registries for cleft lip and palate—experiences from the swedish cleft lip and palate registry

Objective: To test the reliability of the speech data in the Swedish quality registry for cleft lip and palate. Design: Retrospective study. Setting: Primary care university hospital. Participants: Ninety-four children born with cleft palate with or without cleft lip between 2005 and 2009 who had been assessed and registered in the quality registry at the age of 5 years. Main Outcome Measures: Dat

Challenging the heterogeneity of disease presentation in malignant melanoma—impact on patient treatment

There is an increasing global interest to support research areas that can assist in understanding disease and improving patient care. The National Cancer Institute (NIH) has identified precision medicine-based approaches as key research strategies to expedite advances in cancer research. The Cancer Moonshot program (https://www.cancer.gov/research/key-initiatives/moonshot-cancer-initiative) is the

Structure and burning velocity of turbulent premixed methane/air jet flames in thin-reaction zone and distributed reaction zone regimes

A series of turbulent premixed methane/air jet flames are studied using simultaneous planar lase diagnostic imaging of OH/CH/temperature and CH/OH/CH2O. The Karlovitz number of the flames ranges from 25 to 1500, and the turbulence intensity ranges from 16 to 200. These flames can be classified as highly turbulent flames in the thin reactions zone (TRZ) regime and distributed reaction zone (DRZ) re

Rearrangements to vinyl substituted hetero- and carbocycles : Total synthesis of siphonazole B and otherapplications in oxazole and saturated ringsynthesis

The aim of this thesis is to explore and develop new reactions for rapid generation of molecular complexity. Byenabling access to important molecules in a less wasteful and more cost-efficient manner such developmentbenefits the whole modern society, where increasingly complex molecules are needed to solve problems withinfields ranging from medicine, to materials sciences and the perfume industry.

Identification of lignin oligomers in Kraft lignin using ultra-high-performance liquid chromatography/high-resolution multiple-stage tandem mass spectrometry (UHPLC/HRMSn)

Kraft lignin is the main source of technically produced lignin. For the development of valuable products based on Kraft lignin, its molecular structure is important. However, the chemical composition of Kraft lignin is still not well known. So far, the analysis of Kraft lignin by mass spectrometry (MS) has been mainly focused on monomeric compounds. Previous MS studies on lignin oligomers (LOs) co

Behavior change - a key aspect of injury preventive training in youth sport

Injury preventive exercise programs in community sport are of great importance to increase the well-being and engagement of youth in regular physical activity, exercise and sport from a lifespan perspective. In addition, effective Injury preventive exercise programs will indirectly contribute to enhanced sports performance; however research is needed to better understand the strategies to successf
