Previously the effect of atmospheric dispersion on telescope performance has attracted only relatively little attention. This may be due to the fact that the dispersion effects have been evaluated in relation to the size of the diffraction limited resolution angle of current telescopes, or to seeing limited telescopes. However, since the resolution angle is inversely proportional to telescope diam
Popular Abstract in Swedish I december 1990 antog riksdagen i Sverige ett miljötillägg i skollagens s k portalparagraf: "Var och en som verkar inom skolan skall främja? respekt för vår gemensamma miljö." Alltså: Alla som verkar i skolan ska nu ta sig an den nya miljötematiken i samhället. Strax därefter tillsatte regeringen en ny läroplanskommitté med ett tydligt miljöuppdrag. I juni 1992, vid FNThis thesis explores the various influence processes that take place in connection with the dawn of a new theme - the environment - in today's society. Society has declared that schools, a place designed for the intentional influence of children and youths, shall utilise the new environmental theme in its practice. It focuses on the initiation process of the environmental theme in schools from the
The Paris Agreement requests a substantial reduction of greenhouse gas (GHG) emissions. These emissions are currently mainly estimated from bottom-up inventories and process-based models of land and ocean fluxes. Another, complementary approach is based on measurements of the atmospheric GHG concentration in combination with atmospheric inverse modelling to provide the GHG fluxes. For the latter a
The sharing of digital information between phases in the planning and building process still have shortcomings. Ourstudy is performed as a test case on a construction project in a municipality and focuses on two aspects of how the sharing of building information could be improved: 1) to get a more process oriented approach to the information flow. Here we will test if the ISO-standard Product Life
Abstract Body:Starting out from a joint Nordic collaboration initiative in 2008 resulting in the development of a Nordic Master Program in Gerontology (NordMaG), followed by the establishment of graduate schools integrated with two national excellence centers for aging research in Sweden, in 2014 the Swedish National Graduate School for Competitive Science on Aging and Health (SWEAH) was establish
We have investigated the photoionization and photofragmentation yields of gas-phase multiply protonated melittin cations for photon energies at the K-shell absorption edges of carbon, nitrogen, and oxygen. Two similar experimental approaches were employed. In both experiments, mass selected [melittin+qH]q+ (q=2–4) ions were accumulated in radiofrequency ion traps. The trap content was exposed to i
Background: Admission lactate and lactate clearance are implemented for risk stratification in sepsis and trauma. In out-of-hospital cardiac arrest, results regarding outcome and lactate are conflicting. Methods: This is a post-hoc analysis of the Target Temperature Management trial in which 950 unconscious patents after out-of-hospital cardiac arrest were randomized to a temperature intervention
INTRODUCTION: Our main aims were to establish criteria for early distinction between meningococcal disease and other conditions with similar clinical features, and to identify other causes of haemorrhagic rashes accompanied by fever.MATERIALS AND METHODS: This prospective study comprised 264 infants and children hospitalised with fever and skin haemorrhages.RESULTS: We identified an aetiological a
Attosecond pulses allow for imaging of very fast processes, like electron dynamics. Stockman et al. suggested to use these pulses in connection with a Photoemission electron microscope (PEEM) to study the ultrafast dynamics of plasmons (Stockman et al. Nat Photonics 1:539–544, 2007). For efficient plasmon studies, the repetition rate of the attosecond pulses used needs to be higher than a few kHz
Aim: Childhood cancer patients are subjected to recurring painful medical procedures. In low- and middle-income countries (LMIC), where the majority of the world's childhood cancer patients live, pain management is often unsatisfactory due to limited resources. This study aimed to evaluate the possibility of conducting a preprocedural preparation for lumbar punctures (LPs) at a pediatric oncology
Cloud Storage Providers (CSPs) offer solutions to relieve users from locally storing vast amounts of data, including personal and sensitive ones. While users may desire to retain some privacy on the data they outsource, CSPs are interested in reducing the total storage space by employing compression techniques such as deduplication. We propose a new cryptographic primitive that simultaneously real
Purpose: Onyx® embolization causes severe artifacts on subsequent CT-examinations, thereby seriously limiting the diagnostic quality. The purpose of this work was to compare the diagnostic quality of the tailored metal artifact reducing algorithms iMAR to standard reconstructions of CTA in patients treated with Onyx® embolization. Method: Twelve consecutive patients examined with Dual Energy CTA a
Purpose: Neurofilament light (NfL) is a biomarker reflecting neurodegeneration and acute neuronal injury, and an increase is found following hypoxic brain damage. We assessed the ability of plasma NfL to predict outcome in comatose patients after out-of-hospital cardiac arrest (OHCA). We also compared plasma NfL concentrations between patients treated with two different targets of arterial carbon
In this study we used a large previously built database of 2,892 mammograms and 31,650 single mammogram radiologists' assessments to simulate the impact of replacing one radiologist by an AI system in a double reading setting. The double human reading scenario and the double hybrid reading scenario (second reader replaced by an AI system) were simulated via bootstrapping using different combinatio
Outcome prognostication after cardiac arrest (CA) is challenging. Current multimodal prediction approaches would benefit from new biomarkers. MicroRNAs constitute a novel class of disease markers and circulating levels of brain-enriched ones have been associated with outcome after CA. To determine whether these levels reflect the extent of brain damage in CA patients, we assessed their correlation
Popular Abstract in Swedish Robust konstruktion handlar om hur produkter skall konstrueras för att bli okänsliga mot oväntade störningar och variationer i t.ex. omgivningen under drift. Normalt har detta problem angripits med den sk. Taguchi-metoden, i vilken experiment utförs efter en viss metodik på en prototyp, varefter produktens beteende kartläggs och konstruktionsvariablerna väljs så att ettThe activity of robust design of mechanical products and how it can be accomplished in pre-prototype design phases, is discussed in this thesis. It is advocated that to be fully efficient and effective optimization of product robustness should commence already in the conceptual design phase. Moreover, since product optimization is a process, robust design should be perceived and implemented as a p
Alltsedan det kalla kriget slutade har försvarssektorn, framförallt militär logistik och försvarsmaterielanskaffning, genomgått en genomgripande transformation. Flera faktorer har bidragit till transformationen: förändringar i länders och organisationers försvars- och säkerhetspolitik; reducerade försvarsbudgetar; deltagande i fredsbevarande och fredsframtvingande operationer; erfarenheter från deSince the ending of the Cold War, the defence sector, particularly the areas of military logistics and defence acquisition, has been undergoing a comprehensive transformation. There are several factors that explain this transformation: changes in defence and security policies for nations and organisations; reductions in defence expenditure; participation in Peace Support Operations; Lessons Learne
This thesis is a compilation thesis with the title Young persons at homes for care or residence. On legal security, legitimacy and trust with respect to decisions on young persons in care. The thesis is the result of two research projects within the scope of my research studies at the Faculty of Law, University of Lund, Sweden. The two separate studies share the common theme of the influence of le
