Ljus kan användas till många saker, allt från att sända radiosignaler och skicka information i optiska fibrer, till att lysa upp hem och utvinna energi via solceller. Det ljus vi är mest vana vid som människor är ett intervall av våglängder mellan 400 och 700 nanometer (en nanometer är en miljarddels meter), som svarar mot alla synliga färger mellan rött och violett. Ett sätt att undersöka sammansIn this thesis we discuss a theoretical description of ultrafast and non-linear spectroscopy. Due to the high intensities and ultrashort pulse durations involved in such experiments, it is necessary to use an explicitly time-dependent formalism. In addition, many of the systems we have considered exhibit strong interactions between the constituent particles, such as electron-electron, electron-nuc

Objective: To describe the prevalence, baseline characteristics and factors associated with survival in out-of-hospital cardiac arrest (OHCA) with initial non-shockable rhythm sub-grouped into pulseless electrical activity (PEA) and asystole as presenting rhythm. Methods: The Swedish Registry of Cardiopulmonary Resuscitation is a prospectively recorded nationwide registry of modified Utstein param

Försäkringsrätten är till sin karaktär väldigt speciell eftersom avtalsförhållan-det rör de två primära avtalsparterna, men också övriga premiebetalare. Både genom utfallet men också genom bedömningen som sedermera blir vägle-dande för övriga försäkringstagare. En variant på försäkring är den allomfat-tande allriskförsäkringen, som till sin karaktär ska vara mer heltäckande än en reguljär egendomsInsurance law is inherently unique because the contractual relationship primar-ily involves two main parties but also impacts other premium payers. This occurs both through the outcome of disputes and through the interpretative precedents established, which subsequently guide other insurance holders. One form of insurance is the comprehensive "all-risk" insurance, designed to be more inc

In this thesis I examine the view on nature and the view of man in relation to nature, from the two perspectives of the bishops of the Church of Sweden and the Pope of the Roman Catholic Church. I do this based on Cecilie Rubow's theory of three ecologies. This theory, which is also my method, criticizes Christian anthropocentrism in light of the climate crisis. Rubow argues that western theol

Human trafficking is an exploitative crime occurring worldwide. According to the International Organization on Migration (IOM), research on human trafficking’s underlying causes is lacking; particularly the role of climate change and natural disasters. Environmentally displaced persons (EDPs) are vulnerable to human trafficking, but this connection is not widely understood. In order to contribute

This thesis investigates the climate impact of a newly constructed residential complex in Oceanhamnen, Helsingborg, through an extended life cycle assessment (LCA) covering both building and non-building elements such as road infrastructure, inner courtyards, external installations, that area often overlooked in conventional assessments. The aim is to develop a replicable method to quantify the gl

I september 2017 fick nazistiska Nordiska Motståndsrörelsen demonstrationstillstånd i Göteborg, vilket orsakade en stor debatt i Sverige. En liknande debatt väcktes i USA 1977 när en nazistisk grupp ansökte om att demonstrera. Händelserna väcker frågor; bör demonstrationsfriheten innefatta nazistiska demonstrationer? Vad är statens förhållningssätt till våldsamma motdemonstranter? Syftet med uppsaIn September 2017, the Nordic Resistance Movement received a permit to march through Gothenburg, which ignited a big debate in Sweden. A similar debate was had in 1977 in the United States (U.S.), when a neo-Nazi group applied for a permit to demonstrate. These events provoke questions; should the right to demonstrate include neo-Nazi groups? What should the state’s approach be to violent counter-

In this paper, we propose a design framework for distributed embedded control systems that ensures reliable execution and high quality of control even if some computation nodes fail. When a node fails, the configuration of the underlying distributed system changes and the system must adapt to this new situation by activating tasks at operational nodes. The task mapping as well as schedules and con

In this essay I have examined the factors that may be underlying the fact that the co-operation between the Trade Union Confederation, LO, and the Social Democratic Workers Party, SAP, in Sweden is still strong. In Norway and Denmark this collaboration broke a few years ago and so I made an account of various factors that may have contributed to this break in Norway and Denmark, which I then compa

In this work we present the quasi-steady state simulation of a regenerative organic Rankine cycle (ORC) integrated in a passenger vessel, over a standard round trip. The study case is the M/S Birka Stockholm cruise ship, which covers a daily route between Stockholm (Sweden) and Mariehamn (Finland). Experimental data of the exhaust gas temperatures, engine loads, and electricity demand on board wer

Coastal erosion in Mozambique: Governing processes and remedial measures. Mozambique's 2800-km-long coastline comes with associated vulnerability to coastal erosion, their processes, and resulting evolution. In fact, coastal erosion has been identified as a dominant phenomenon in the Mozambican coastal system. It is driven by a combination of natural processes and anthropogenic actions. Despite th

In our homes we enjoy daylight reaching the rooms through the windows, and artificial lighting when there is not enough daylight available. Electrical lighting has been used in Western homes since the late 1910s. We have experienced the technical development from warm incandescent light bulbs to energy-efficient light emitting diods (LED). In Sweden we lack daylight in winter and have a lot of day

The relationship between local labour market conditions and regional migration has been widely discussed within research. In Sweden, where interregional migration reached a peak in the 1960s but decreased substantially in the 1970s, the role of economic policy has been especially contended in light of the Swedish model and its official stress on regional mobility. By collecting and creating a new

Substantial evidence now supports the hypothesis that the common ancestor of bats was nocturnal and capable of both powered flight and laryngeal echolocation. This scenario entails a parallel sensory and biomechanical transition from a nonvolant, vision-reliant mammal to one capable of sonar and flight. Here we consider anatomical constraints and opportunities that led to a sonar rather than visio

Objectives: We aimed to identify and evaluate: (1) treatment-emergent adverse events (TEAE (worse or new since baseline)) and the subgroup of severe TEAEs in a placebo-controlled 7-day randomised trial of regular, low-dose, sustained-release oral morphine for chronic breathlessness and (2) clinical characteristics associated with TEAE. Methods: Safety analysis of trial data. Adults with chronic br

Personal cooling garments (PCGs) can represent an adaptation solution to counteract heat strain and to improve worker's health and productivity (especially for some outdoor work activities as in agriculture and in the construction industry). The cooling effect of a ventilation jacket was preliminarily investigated carrying out “dry” tests in a climatic chamber on a thermal manikin. A standardized

How can anthropologists negotiate access in high-profile, bureaucratic apparatuses, such as a UN human rights monitoring mechanism – and what can a detailed account of these negotiations tell us of such apparatuses, their operational dynamics and the processes through which they exert an impact, broadly construed? This article addresses these questions through the notion of tactical subjectivity b

An acoustofluidic device, consisting of a polymer chip with a long straight channel, coupled to a piezoelectric transducer is modeled numerically in three dimensions and compared to experimental results in terms of the electric admittance as well as the ability to focus particles. In our experiments we obtain good acoustic particle focusing at a frequency of f = 1.14 MHz with an actuation voltage

I sitt tidiga verk Om empatins problem (Zum Problem der Einfühlung) försöker Edith Stein ”specificera empatins speciellt intentionella karaktär” (Zahavi 2001,158). Ett övergripande mål för Stein är att finna de element som konstituerar en individ som en ”annan” för oss. Ett liknande syfte återfinns i skrifter som koncipierades delvis under samma tid på ett annat kunskapsområde, skådespelarkonstensIn her early work On the problem of empathy, (Zum Problem der Einfühlung), Edith Stein attempts to ´specify the particular intentional character of empathy´ (Zahavi 2001, 158). An overall aim for Stein is to find out the elements of what constitutes an individual as an ´other´ for us. A similar aim is present in writings that were conceived partly at the same time within another field of knowledge
