A thorough understanding of the longitudinal phase space (LPS) of the electron beam is of great advantage to any modern linear accelerator (linac), and of critical importance for operating a free electron laser (FEL). While a transverse deflecting structure (TDS) allows full characterization of a beam’s LPS, measurements with a TDS system are often destructive and operationally complex.

Mozambique, situated in south-east Africa, has sub-tropical and tropical climate and plenty of natural resources for energy production. The country is however poor, and only about 25% of the population has access to electricity from the grid. A very large part of the energy used in the country is used in the residential sector, and there is a general lack of knowledge, regulations and tools concer

Background: Prescription sedatives are efficient in the treatment of anxiety and sleeping disorders, but are associated with a risk of misuse and dependence, as well as an increased risk of accidents, injuries and overdoses, both in the general population and especially in individuals with other substance misuse. The present thesis aims to investigate prescription sedative use and misuse in two ki

Popular Abstract in Swedish Bakgrund Kroppen har många olika försvarsmekanismer för att skydda sig mot angrepp av olika slag. Bland försvarsmekanismerna i immunförsvaret finns förmågan att bilda antikroppar. Antikroppar, eller immunglobulin, är lösliga protein och består av fyra polypeptidkedjor som hålls samman av svavelbindningar. Dessa kedjor har en variabel ände som ger upphov till molekylensAntibodies are important protein structures in the immunological defence. Occasionally the regulation of the production of these antibodies fails and antibodies directed against self structures are produced in large scale. Antibody production can also complicate or make transfusions and transplantations impossible. Purified protein A from Staphylococcus aureus immobilised to beaded agarose can ads

Popular Abstract in Swedish Systemisk lupus erythematosus (SLE) är en autoimmun reumatisk systemsjukdom som drabbar flera av kroppens olika organsystem, såsom rörelseapparat, hud och inre organ. Vidare ses en mångfald störningar i kroppens immunsystem. Sjukdomen drabbar oftast kvinnor. Vad som orsakar SLE är ännu så länge ofullständigt klarlagt, men man vet att yttre faktorer (miljöfaktorer) samveSystemic lupus erythematosus (SLE) is a complex autoimmune disease in which environmental factors interact with genetic factors in the development of the disease process and evolution of clinical manifestations. In this thesis both exogenous factors and host factors were investigated, as well as important immunopathological aspects including involvement of immune complex (IC), the complement syste

Popular Abstract in Swedish Patienter med kroniskt obstruktiv lungsjukdom, KOL, har en försämrad lungfunktion och lider av bronkit och andnöd. Dessa symptom beror troligtvis på en ständigt pågående inflammation i lungan som dels leder till ökad slemproduktion och förträngning av luftrören, dels till emfysem dvs. nedbrytning av lungvävnaden vilket försämrar gasutbytet i lungan. Cigarrettrökning är Chronic obstructive pulmonary disease, COPD, is manifested by chronic airflow limitation due to inflammation and tissue destruction in the lungs. COPD is caused primarily by smoking and with increasing cigarette consumption in the world, the prevalence for COPD will most probably increase in the future. The chronic inflammation in the lungs of these patients is thought to drive the pathogenesis fo

Popular Abstract in Swedish Under de senaste decennierna har förhoppningar om en ökad andel manlig personal i förskolans verksamhet uttryckts från samhällets sida. Förhoppningarna har dock inte infriats och antalet yrkesverksamma manliga förskollärare var cirka två procent i slutet av 1990-talet. Denna könsmässigt underrepresenterade grupp, som i sin yrkesutövning befinner sig i en kraftigt könsmäThe aim of this study is to describe and analyse the situation of male teachers in the day-to-day work of pre-school, taking into account the fact that men are underrepresented in this profession. The methodic field is qualitative. Video recordings and interviews have been carried out with the fourteen male pre-school teachers who have participated in the project. Some of these men work together w

Popular AbstractWhen society first perceived the environmental condition as problematic, focus was on local emissions with local consequences. Subsequently, the center of attention partly moved beyond local effect research to a broader interest in, for instance, ecocycle processes of energy, and the whole lifecycle of materials. However, technological and natural scientific analyses of these phenoThe book has two interrelated objectives. One objective is meta-theoretical and concerns the exploration of theoretical debates connected to issues of studying society and environmental problems; another objective is empirical/analytical, referring to the analysis of "green" public participation in the electricity and waste sectors in Sweden, and partly in the Netherlands as well as the UK. The me

Popular Abstract in Swedish Människans immunsystem utgörs av en komplex sammansättning av celler och molekyler, som interagerar med varandra men även med kroppens övriga vävnader. Dess huvudsakliga uppgift är att förse sin värd med ett försvar mot yttre och inre förhållanden, som kan orsaka denna skada, t.ex. bakterie- och virusinfektioner eller betingelser för utveckling av cancer. Denna försvarsThis thesis is based upon four original papers in which human dendritic cells (DCs) and B cells have been analyzed in terms of how they influence the character of adaptive immune responses. DCs isolated from human tonsils were found to possess a capacity to directly regulate proliferation, isotype switching, and antibody production in B cells. DC-produced cytokines, including IL-13, were identifie

Förorenaren betalar är en ekonomisk princip som internaliserar externa kostnader. Principen är således en metod genom vilken kostnader för förorening kan bli fördelade. Principen kan också beskrivas genom att använda ett rättviseargument, eftersom det kan anses rättvist att förorenaren ska betala för den förorening som han bidragit till. Förorenaren betalar har använts i internationell rätt och anThe polluter pays principle is an economic principle through which external costs can be internalised. The principle is thus a way of allocating costs for pollution. The principle can also be described using a fairness argument, where it would seem fair that the polluter pays the costs for the pollution which he has contributed to. It has been extensively used in international law, and has been re

The no-supply rule provided for in Article 19 and 29 of the Directive constitutes a deviation from the system of VAT. It enables Member States to consider that no supply of goods or services has taken place in the event of a transfer of a totality of assets or part thereof. Although the practice of the Court of Justice sheds light on some issues relating to the transfer of business (what exactly t

The purpose with this work has been to develop and construct a Niobium target for the production of [18F]fluoride with a MC 16 Scanditronix cyclotron. The future demand larger amounts of [18F]fluoride and to satisfy the forthcoming needs an enhanced target needs to be installed on the cyclotron. The old target could have provided the forthcoming needs but to obtain good margins it is important wit

Popular Abstract in Swedish Evangelium Cyrillicum Gothoburgense, ECG, ett tetraevangelium som förvaras i Göteborgs universitets-bibliotek, har studerats i flera avseenden. Den kodikologiska studien visar att handskriften har restaurerats tidigare och att några sidor fattas i början och i slutet. Vattenmärket är ett vildsvin, vilket daterar ECG till 1605-1625 med stöd av ett identiskt vattenmärke iEvangelium Cyrillicum Gothoburgense, ECG, a tetraevangel treasured in Göteborg University Library, has been studied from several aspects. A codicological study showed that the MS bears signs of earlier restoration and that some leaves are missing at the beginning and at the end. The watermark is a "boar", and the date of ECG is believed to be 1605-1625 on the basis of an identical watermark in ano

Popular Abstract in Swedish Ett stort problem med samhällsvetenskapliga studier som på ett eller annat sätt behandlar informationsteknologins följder är att det är svårt, ibland helt omöjligt, att jämföra resultat och slutsatser. Detta beror delvis på att man behandlar ”informationsteknologi” eller ”IT” på så olika vis. Någon kanske konceptualiserar ”IT” som att vara en viss typ av hemsidor, andraThis work has two main ambitions. First, we will develop a generic framework which, properly used, can drastically reduce the intrinsic complexity of the continually evolving IT-environment, making it less unwieldy. That should prove advantageous for anyone trying to analyse social aspects of the moving target that is classified as "IT". Using (and at the same time demonstrating) his framework, w

I den här uppsatsen behandlas preferensaktier och fokus ligger på emittenter som är börsnoterade bolag. Utgångspunkten i svensk rätt är den så kallade likhetsprincipen som innebär att alla aktier ska ha samma rätt i bolaget. Undantag från detta kan göras om det finns lagstöd för och om det förs in i bolagsordningen att olika aktieslag får förekomma i bolaget – exempelvis preferensaktier. PreferensThis essay is about preferred stocks and focus is on issuers that are companies listed on regulated markets. The main rule in Sweden is the so-called principle of equality, which states that all stocks shall have the same right in the company. Exceptions to this may be made if there are legal grounds for it and if it is entered in the Articles of Association that different classes of stocks may ex

In any given industry, fragmentation, namely the state of a disintegrated landscape of market participants’ offerings, can have detrimental effects on firms and customers in the likes of inefficiencies or inconvenient offerings, respectively. Despite recent first steps towards consolidation of offerings through, for example, platform ecosystems, the German mobility industry is still largely fragme

År 2018 införlivades Europeiska Unionens dataskyddsförordning i svensk rätt och dataskydd som ämne fick en allt större uppmärksamhet i media och i debatt. Dataskyddets framväxt började dock tidigare än så och är en viktig fråga för både enskild individ som för stat och företag. Tack vare en snabb teknisk utveckling och smarta algoritmer är personlig information en allt mer värdefull tillgång hos In 2018, the European Union's General Data Protection Regulation (the GDPR) was incorporated into Swedish law, and data protection as such was increasingly noticed and given attention in the media. However, the emergence of data protection began a lot earlier than 2018 and is an important matter as for both individuals such as the state and companies. Through rapid technological development a

This project is a collaboration with Electrolux, KTH Royal Institute of Technology and the School of Industrial Design (Lund University). The goal of the project was to investigate new ways of cooling an individual, to ultimately result in a product proposal. We have all experienced heat waves in the summer, which can affect us even in our homes. In addition, typical home activities such as cleani
