The essay argues that between the world we aim to study and the realities we describe there is no straight, neutral relation. Instead, through our scientific practices we simplify that world as well as contribute to shape it. Methods are not mere procedures to mirror the world; rather, methods mediate between the world and our descriptions of it, and in the process they contribute to both simplify

In type 1 diabetes, pancreatic beta cells are destroyed by chronic autoimmune responses. The disease develops in genetically susceptible individuals, but a role for environmental factors has been postulated. Viral infections have long been considered as candidates for environmental triggers but, given the lack of evidence for an acute, widespread, cytopathic effect in the pancreas in type 1 diabet

We considered nonlinear solvers inside implicit time integration schemes for the time dependent compressible Navier-Stokes equations. The existing solvers turn out to be adequate, but amenable to significant improvements. Regarding multigrid schemes, we demonstrated that reoptimizing a multigrid scheme for the case of a time dependent equation leads to significant improvements in convergence speed

OBJECTIVE: To present findings that suggest steroid treatment within 24 hours of onset of vestibular neuronitis results in better restitution of vestibular function than treatment between 25 and 72 hours. PATIENTS: Thirty-three consecutive patients (17 men, 16 women, mean age 57 yr, range 17-85 yr) with acute vestibular neuronitis and treated with steroids within 72 hours after symptom onset. Pati

Phased array antennas are cornerstones in many proposed antenna solutions concerning the next generation of both airborne radar systems and wireless communication systems (5G). Additionally, millimeter wave (mm-wave) frequencies are expected to play an integral role in 5G, and are deemed well-suited for inspecting structural components used in the aerospace industry.This dissertation consists of a

Aims. We aim to measure lifetimes of levels belonging to the 3d 3 ( 4 F)4d subconfiguration in Va II, and derive a

Different virtual reality (VR) experimental tools and equipment are available for evacuation research, ranging from highly immersive systems such as cave automatic virtual environments (CAVEs) to head-mounted displays (HMDs). In particular, mobile-powered HMDs are an extremely cost-efficient solution, for which the research potential for evacuation studies needs to be assessed. This study compares

Some theoretical approaches are reviewed to analyze crystallographic and optical properties of phosphors for white light emitting diodes. Stresses are placed on 1) local electro-neutrality for the structural stability of hosts, and 2) dielectric property and coordination of anion ligands around rare-earth luminescent centre for the tuning of emission colour. First-principles calculation results ar

In this chapter, we discuss the need for deeper knowledge about the relation between people’s daily activities and their electricity use and how to increase our knowledge through time use surveys and the visualization of aggregate activity patterns. To understand people’s energy consumption and how to improve energy efficiency or reduce demand during certain peak hours requires an understanding of

Regional climate and energy planning in Sweden has long been fairly weak. Starting in 2008, however, the regional administrative level was strengthened, when the County Administrative Boards (CABs) were commissioned to develop regional climate and energy strategies. Coordinating and involving various stakeholders in the strategy work was essential to the assignment. The process of developing these

The study of quantum thermal machines, and more generally of open quantum systems, often relies on master equations. Two approaches are mainly followed. On the one hand, there is the widely used, but often criticized, local approach, where machine sub-systems locally couple to thermal baths. On the other hand, in the more established global approach, thermal baths couple to global degrees of freed

Background: Recent studies have identified several single-nucleotide polymorphisms (SNPs) associated with the risk of breast cancer and parity and age at first childbirth are well established and important risk factors for breast cancer. The aim of the present study was to examine the interaction between these environmental factors and genetic variants on breast cancer risk. Methods: The Malmö Die

Dysfunction of the gastrointestinal tract has now been recognized to affect all stages of Parkinson's disease (PD). The consequences lead to problems with absorption of oral medication, erratic treatment response, as well as silent aspiration, which is one of the key risk factors in developing pneumonia. The issue is further complicated by other gut abnormalities, such as small intestinal bacteria

Detta är en kort rapport inom projektet ”Mätsystem för förändringsarbete”, utfört vid Institutionen för teknisk ekonomi och logistik vid Lunds Tekniska Högskola. Rapporten skall ses som ett komplement till slutrapporten ”Mätning av förändringsarbete: Utveckling och implementering av ett mätsystem för att mäta förändringstemperatur”.Projektet syftade till att ta fram ett ramverk för förändringsarbe

Emboldened by the aesthetic,- emotional-, and corporeal turns in the study of world politics, International Relations (IR) scholars are increasingly paying attention to the political dimension of affects and emotions. Yet while, so far, affect and emotions have been studied as (micro-political) forces that circulate between bodies in the context of the everyday, little attention has been given to
