Kiralitet (från grekiskans cheiʹr ’hand’) är en symmetriegenskap som är viktig bland annat inom kemin. En kemisk förening kallas kiral om den skiljer sig från sin spegelbild. De två spegelbildsformerna (även kallade enantiomerer) förhåller sig till varandra som en högerhand till en vänsterhand – hur du än vrider och vänder på den ena kan du inte få den att överlappa med den andra. Två enantiomererTwo novel pseudo-Cs-symmetric heterobimetallic bissalen complexes have been synthesized, one containing chromium and cobalt and the other containing chromium and manganese. The design is based on a previously unexploited method; breaking the symmetry of an achiral meso-ligand by insertion of two different metal ions. The synthesized complexes are expected to catalyze the asymmetric ring-opening of

This report covers the process of a project that resulted in a future concept for an autonomous bike-sharing system. It started with a desire to do transportation design and to explore the future of public transit and the role of the bicycle in it. The research phase started with trying to form an understanding of the current public transportation situation for cyclists and also looking into futur

Pupil dilation is a reliable measure of cognitive load, and many studies have shown this effect in relation to various memory tasks. Interference from irrelevant memory traces encoded in the past lead to difficulty retrieving recent, sought after memory traces, and increased cognitive load. This investigation showed a significant decline in performance during buildup of interference and a signific

The aim of this study has been to highlight individuals own experiences of the recovery process from exhaustion disorder. By taking part of their experiences advancement and obstructive, internal plus external factors that has been decisive for their recovery could be identified. To answer the aim a selection of six autobiographies about recovery from exhaustion disorder was made. A text analysis

Syftet med studien är att ta reda på vilka kunskaper som socialarbetare har när det gäller nära relationer med våld mot kvinnor med funktionshinder. Jag har gjort en kvalitativ studie med intervjuer, och jag har gjort fem intervjuer med socialarbetare från fyra kommuner i västra Sverige. När det gäller relationer med våld mot kvinnor med funktionshinder, har jag funnit olika typer av kunskap, somThe purpose of the study is to find out what experience the social workers have of violent relationships involving women with physical disabilities. I have done a qualitative study with interviews, and I have done five interviews with social workers from four municipalities in Western Sweden. I have tried to find out what the different types of knowledge are, and to what degree this knowledge is

Översvämningsmodellering Idag används matematiska modeller, i form av datorprogram, för att simulera konsekvenser av framtida översvämningar. Det finns en stor uppsjö av modeller med olika möjligheter och begränsningar, så hur går vi egentligen till väga för att välja modell? Översvämningar hör till de naturliga katastrofer som gör störst skada. Mellan 1998 och 2009 krävde de 216 största översväHydraulic models can be used to predict the consequences of flooding events. In this project, three hydraulic models were constructed using the software HEC-RAS, and compared through a case study on Höje river catchment. The models include (i) a 1-dimensional (1D) model, where river and floodplain flow is modeled in 1D, (ii) a coupled 1D-2D model, where river flow is modeled in 1D and floodplain f

Trollsländor i stafett över säsongen En härlig vårpromenad, citronfjärilen fladdrar förbi längs stigen och i himlen flyger tranorna trumpetande norrut. Två månader senare, samma stig. Nu är det inte citronfjärilar och tranor som möter dig, istället ser du en blågrön mosaikslända disciplinerat patrullera fram och tillbaka längs med stigen. Vad är det som gör att vi får så olika upplevelser beroeA species phenology is central to its ecology. Phenology is linked to development time and in extension size. Phenological differences can be found in both inter- and intraspecific comparisons. Sexual dimorphisms in phenology (protandry and protogyny) has been linked to sexual size dimorphism (SSD). In this study I use odonates, popular model organisms for studies of development and sexual dimorph

In this essay I have tried to study and examine how users of illegal narcotic substances reach out for help and support on Drogakuten, a sub forum on the message board Flashback forum instead of turning to the health care system. I have tried to look at the interaction between the members to see if there is a harm reduction philosophy present on the board. I have also tried to analyze Drogakuten a

Children’s participation could seem to be an obvious ingredient in social services child protection investigations. Children’s rights to make their voice and opinion heard and to affect the decisions that involve them is stated in law, conventions and other regulations. Despite this, a lot of previous studies show that children’s rights often are forgotten or non-prioritized in social services. Th

Previous studies within the field of prejudic

Uppsatsen kretsar kring diskussionen om dementa personers rättsliga ställning i deras kontakt med vård och omsorg. Det allmänna har en skyldighet att skydda utsatta individer och ge dem möjlighet att leva ett värdigt liv. Samtidigt är ett centralt värde att vård och omsorg ska bedrivas med respekt för människors självbestämmande och integritet.

För många innebär datorspel att kliva in i den fiktiva värld som spelet skapar och på så vis undgå verkligenheten. I forskningssammanhang är det precis tvärtom, då är datorspel eller mikrovärldar som det också kallas ett sätt att simulera verkligheten. I detta examensarbete har möjligheten att använda datorspel för studier inom riskhanteringsområdet undersökts. Då det tidigare inte fanns någon miIt has been shown that it can be difficult to study decision making in a risk management context when traditional methods are used. An alternative to traditional methods is to use micro worlds. A certain type of decision making in the risk management context is about investments in capability which has been studied in this thesis. The aim of the project is divided into two parts, where the first p
