Background: Brief screening instruments focusing on autism spectrum disorder (ASD) that can be administered in primary care are scarce; there is a need for shorter and more precise instruments. The Autism-Tics, AD/HD and other Comorbidities inventory (A-TAC) has previously been validated for ASD reporting excellent validity. This study aims to determine the psychometric properties of each item in

Background: Meniscus injury and meniscectomy both entail increased risk of knee osteoarthritis (OA). Thigh muscle weakness is a suggested mediator of OA but there is little evidence of its importance for knee OA development after meniscectomy. This study aimed to examine the association between thigh muscle strength after partial meniscectomy in middle-aged subjects with a non-traumatic meniscal t

Introduction Fever is an integral part of the inflammatory response and has therefore likely a physiological role in fighting infections. Nevertheless, whether fever in itself is beneficial or harmful in adults is unknown. This protocol for a systematic review aims at identifying the beneficial and harmful effects of fever control interventions in adults. Methods and analysis This protocol for a s

Avhandlingsarbetet studerar hur turbulent flödesstruktur sammverkar med förbränning av högoktaniga bränslen i partiellt förblandade förhållanden genom numeriska tredimensionella flödessimuleringar. Förbränningsmoder och antändningsprocesser studeras för två olika typfall där ett flertal metoder testas med ändamålet att korrekt återge hur icke upplöst rörelsemängd växelverkar med de kemiska processThis work treats the modelling of PPC engine combustion through 3D computational fluid dynamics. In order to develop a cost-effective CFD model for the design and performance analysis of PPC engines it is important to first understand the multiple modes of combustion in PPC engines, e.g., the onset of the first ignition kernels, the propagation of the ignition/flame fronts, and the effect of charg

En ökning av andelen kollektivtrafik är en viktig del av omställningen mot lägre utsläpp av växthusgaser och mer energieffektiva transporter. I Sverige har antalet resor med kollektivtrafiken ökat med 18% mellan åren 2009 och 2015. Det finns dock en stor skillnad mellan olika regioner där ökningen varit över 20% i flera regioner medan utvecklingen av resandet har stagnerat, eller till och med mins

Context. In the advent of new infrared high-resolution spectrometers, accurate and precise atomic data in the infrared are urgently needed. Identifications, wavelengths, strengths, broadening, and hyper-fine splitting parameters of stellar lines in the near-infrared are in many cases not accurate enough to model observed spectra, and in other cases, these parameters do not even exist. Some stellar

This thesis deals with the addition of upconversion detection to non-linear mid-infrared laser spectroscopy techniques. The techniques investigated here are degenerate four wave mixing (DFWM) and infrared polarization spectroscopy (IRPS). These techniques are useful for detecting many of the key species in combustion, such as CH4, C2H6, HCl, and HCN. These species can be probed using ro-vibrationa

This paper examines the response of five prominent Swedish economists, David Davidson, Gustav Cassel, Eli Heckscher, Knut Wicksell and Bertil Ohlin, to John Maynard Keynes’s "The Economic Consequences of the Peace" and to the German reparations in the 1920s. When Keynes’s book appeared, Davidson and Cassel strongly endorsed it. Heckscher also agreed with Keynes – “a bright spot in a time of darkne

Många vill nu överge överskottsmålet i det finanspolitiska ramverket. Men det är riskfyllt. Efter den internationella finanskrisen 2008 saknade många länder med hög statsskuld utrymme för en tillräckligt expansiv finanspolitik och tvingades till den hårda åtstramningspolitik som ligger bakom de populistiska strömningarna i Europa, skriver Fredrik N G Andersson och Lars Jonung.

Capacity-building in international cooperation projects is typically founded on a conceptualisation of transmission or transfer, and thus also typically contributes to the international diffusion of certain models, systems or technologies. In European policy, this approach has been part of the strategy to strengthen the position of European HE by making HE structures in other parts of the world co

Mer förnybar energi och elektrifiering av transportsektorn är viktiga sätt att minska vår klimatpåverkan. Det ökade intresset för elbilar har också väckt en diskussion om de geopolitiska konsekvenserna av övergången från bensin till batterier. Vilka blir de nya vinnarna och förlorarna i elektrifieringens spår? Vilken typ av naturresurser används i dessa tekniker? Finns det tillräckligt av dessa re

The aim of this work is the development of a thermodynamically consistent fully coupled finite-strain thermo-viscoplastic material model for metals. The model is based on a split of the free energy into a thermo-elastic, a thermo-plastic and a purely thermal part and covers nonlinear cold-work hardening and thermal softening. Nonlinear temperature dependent effects are accounted for the elastic mo
