Partially premixed combustion (PPC) is an advanced combustion strategy that has been proposed to provide higher efficiency and lower emissions than conventional compression ignition, as well as greater controllability than homogeneous charge compression ignition (HCCI). Stratification of the fuel-air mixture is the key to achieving these benefits. The injection strategy, injector-piston geometry d
Det är hundra år sedan Georg Simmel gick bort. Ett porträtt av den kanske mest infalls- och perspektivrika sociologen – biografiskt, intellektuellt, kulturellt.
The ontogeny of the pelturine olenid trilobite Leptoplastides salteri (Callaway, 1877) from the Shineton Shales, Shropshire, England, was first described in 1925 by Frank Raw. Since that time, scanning electron microscopy and other new technologies have revealed many more details of structure, of early developmental stages in particular, than were available to Raw. Whereas protaspides are not pres
Representing an international, multi-institutional research team, the panel presents a theoretical framework for understanding what prompts academic staff/faculty to change towards sustained use of pedagogies that make a meaningful difference in student learning. The theory grows out of a synthesis of literature on: the role of leadership and resources in emerging changes to teaching practices (Gi
Aim: The aim of this review was to develop a deeper knowledge of the physiology of coronary blood flow and coronary flow reserve in young patients with congenital heart disease and inflammatory diseases. Methods: We searched for papers published in English on coronary blood flow and coronary flow reserve using the PubMed and Google search databases. This identified 42 papers extending back to 1976
OBJECTIVES: To compare 6 minute walking distance (6MWD) in a population-based osteoarthritis (OA) cohort with matched peers from the general population, and to explore the associations between walking ability and CVD risk (arterial stiffness) in the OA cohort.DESIGN: This cross-sectional study included participants (40-80 years) who self-reported OA (n=500) in a population-based study and age- and
INTRODUCTION: We have limited knowledge about the underlying disease mechanisms and causes of pain in hand osteoarthritis (OA). Consequently, no disease-modifying drug exists, and more knowledge about the pathogenesis of hand OA is needed, as well as a validation of different outcome measures. Our first aim of this study is to explore the validity of various imaging modalities for the assessment o
En diskussion om hantverkets natur och särskilt dess möjlighet och begränsningar i en samtid kännetecknad av globalisering, acceleration, automatisering, virtualisering, flexibilitet, anpassning. Även en diskussion om hantverkets möjligheter bortom traditionella sammanhang: hantverk och arbetet med människor, hantverk och respekt, hantverk och empati.
OBJECTIVES: To explore whether smoking and alcohol use are associated with hand osteoarthritis (OA) features in two different OA cohorts.METHOD: We studied 530 people with radiographic hand OA from the Musculoskeletal pain in Ullensaker STudy (MUST) and 187 people from the Oslo hand OA cohort [mean (sd) age 65 (8.0) and 62 (5.7) years, 71% and 91% women, respectively]. Smoking, alcohol use and han
OBJECTIVE: To compare the prevalence of synovitis, pain and radiographic progression in non-erosive and erosive hand osteoarthritis (HOA), and to explore whether the different rate of disease progression is explained by different levels of synovitis and structural damage.DESIGN: We included 31 and 34 participants with non-erosive and erosive HOA at baseline, respectively. Using Generalized Estimat
OBJECTIVES: Few longitudinal studies have studied the association between body mass index (BMI) and hand osteoarthritis (OA). We aimed to explore the association between BMI and progressive hand OA in a longitudinal study of the Oslo hand OA cohort.METHOD: Participants with existing hand OA had hand radiographs and BMI data taken at baseline and 7-year follow-up (n = 103). The radiographs were rea
OBJECTIVES: The aim of this population-based case-control study was to investigate whether a high body mass index (BMI) is a risk factor for clinical hand osteoarthritis (OA).METHOD: Persons living in Ullensaker municipality in Norway who were aged 20-52 years in 1990 reported height and weight in 1990, 1994, 2004, and 2010 (n = 1276). Cases (clinical hand OA in 2010, n = 59) were compared to cont
BACKGROUND: Multisite pain and obesity are cross-sectionally related and are common conditions that may influence each other through socio-demographic, lifestyle and/or health-related factors. The aim of the present study was to examine the cross-sectional and prospective associations between overweight/obesity and multisite pain in a general population.METHODS: In a 20-year population-based prosp
Background: Obesity is a well-known risk factor for osteoarthritis (OA). The majority of obesity research in OA is performed using self-reported BMI-data, however, its validity in persons with OA is unknown. The aim of this study was to compare the validity of self-reported body mass index (BMI) in persons with and without clinical osteoarthritis (OA) in a population-based survey. Methods: Height
The objective of the study was to examine the hand-, knee- and hip osteoarthritis (OA) distribution, risk factor profiles and health-related quality of life (HRQoL) in a population-based OA cohort. Persons with self-reported OA responded to questionnaires and attended a clinical examination (N = 606). We analyzed cross-sectional associations to risk factor profiles and HRQoL dimensions (Short Form
This article analyses the transnational production processes of foreign correspondence in the Cold War. It examines the double role of foreign correspondents as reporters and Cold War political agents. Recent scholarship has explored the activities of Western correspondents reporting from the Communist world. Little is known, however, about Eastern bloc correspondents in the West. Drawing on the r
The last several decades of research on avian cognition have revealed surprising parallels between the abilities of birds — most notably corvids — and great apes. Parrots, albeit far less studied, are cited alongside corvids as “feathered apes”, but are these two taxa really that similar cognitively? In this review we aim to take a step back and present the broader picture, focusing on areas where
Uneasy citizens: constructions of political cynicism among young satire audiencesYoung adult citizens are a mixed group – in both research and media, they’re seen as engaged and disengaged, as well as politically idealistic and cynical (cf. Amnå & Ekman 2014). This paper seeks to further understand this contradiction, by studying the Swedish young adult audience of news satire, a group that ha
In research and media, young Swedes are hailed as engaged and disengaged; politically idealistic and pessimistic (cf. Amnå & Ekman 2015). One of the main resources for young citizens are various forms of political media. Different types and genres are considered more or less relevant, valuable, or in some cases, harmful, to developing a well-rounded, healthy citizenship (cf. Bennett 2008; Dahl
The freedom to express oneself as a citizen is paramount to contemporary democracy. However, this freedom is often questioned in relation to humour and the offence it might cause, especially in cases where humour is referred to as an excuse, as a defence to avoid criticism (Smith 2009). This article uses the concept of cultural citizenship (cf. Hermes 2005) to conceptualise citizen rights and resp
