LDMX is a fixed target experiment designed to search for light dark matter. The experiment will search for dark matter signatures using missing momentum and energy in events with electrons scattering in the target. Part of the experimental setup in this search is a high granularity electromagnetic calorimeter to accurately measure the energies of recoil electrons. In this thesis artificial neura
The transfer of 210Po and 210Pb between various compartments in the terrestrial environment has been analysed by using various published data. The average activity concentration of 210Po in soil is 61 ± 14 Bq.kg-1 d.w. with a median (50%) value of 44 Bq.kg-1 d.w. Ground water concentrations of 210Po in drilled wells might be as high as 6.5 Bq/l. But in regular drinking water it is just about 3-5
This study concerns an arctic marine environment that was contaminated by actinide elements after a nuclear accident in 1968, the so-called Thule accident. In this study we have analyzed five isolated hot particles as well as sediment samples containing particles from the weapon material for the determination of the nuclear fingerprint of the accident. We report that the fissile material in the hy
This thesis is based on four projects with the overall aim to investigate vitamin K-dependent protein S functions in relation to its structure. The anticoagulant functions of protein S can be divided in three: 1) cofactor for activated protein C (APC), 2) cofactor for tissue factor pathway inhibitor (TFPI) and 3) APC and TFPI-independent anticoagulant functions. Microparticles might be shed from
Popular Abstract in Swedish Utvecklingen av laserpulser med extremt hög intensitet har försett forskare med ett verktyg som gör det möjligt att studera vad som händer då dessa pulser växelverkar med olika slags materia. Då växelverkan sker med en gas kan till exempel ultrakorta pulser från ultraviolett till röntgenområdet genereras som övertoner till laserpulsen. Dessa övertoner kan göras kortare The availability of short-pulse, high-intensity lasers has opened doors to new areas in atomic and plasma physics. The short pulses (a few femtoseconds), that are available today, enable unprecedented temporal measurements, while the high peak power accessible (several terawatts) allows physicists to study the interaction between light and relativistic plasmas. The aim of this work was twofold: i)
Popular Abstract in Swedish Många av alla kemiska processer som pågår i våra kroppar utförs av proteiner. När de inte fungerar blir vi sjuka. I vissa fall, till exempel vid Alzheimers sjukdom eller Creutzfeld Jacobs sjukdom, beror det på att ett visst protein har fel form. Att förstå hur proteiner antar sin slutliga form och vad det har för inverkan på proteinets funktion är således viktigt. ÅVery little is known about a considerable part of all proteins and it is time consuming and expensive to study each individual protein to determine its function, structure and cellular role. Proteins retain structural, functional and sequential characteristics from ancestral proteins and hence two proteins that share a common ancestor, i.e. are homologs, will to some extent have similar sequen
1. To investigate further the release, localization and identity of a non-nitrergic mediator of smooth muscle relaxation in the female pig urethra, we studied the effects of drugs acting at alpha 2-adrenoceptors or K+ channels, the effects of capsaicin and chemical sympathectomy, and the actions of several transmitter candidates. 2. Electrical field stimulation (EFS; frequencies above 12 Hz) of sp
The GAIA astrometric mission has recently been approved as one of thenext two ``cornerstones'' of ESA's science programme, with a launch datetarget of not later than mid-2012. GAIA will provide positional andradial velocity measurements with the accuracies needed to produce astereoscopic and kinematic census of about one billion stars throughoutour Galaxy (and into the Local Group), amounting to a
Popular Abstract in Swedish Laser Doppler metoder avsedda för mätning av blodflöde baserar sig på det faktum att fotoner skiftar i våglängd när de träffar blodkroppar i rörelse. Den förändrade våglängden registreras och signalen bearbetas varefter resultatet uttrycks i en godtycklig enhet och anses utgöra ett mått på blodflöde. Laser Doppler Perfusion Monitoring (LDPM) är en metod med vilken blodThe operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. Laser Doppler perfusion
A detailed study of ultraviolet spectra of the symbiotic star AG Peg has been undertaken to derive the atomic excitation mechanisms and origin of formation for the lines common in symbiotic systems. More than 600 emission lines are observed in spectra from IUE, HST and FUSE of which 585 are identified. Population mechanisms and origin of formation are given for a majority of those lines. Based on
The purpose of this study was to illustrate how adolescens from different ethnic groups look at their future. My questions at issues was: What is the adolescens life look like in twenty year considering: education, the worksituation, familysituation and connection with their country of origin? What's the meaning of the conception future for the adolescens? How do the dreamfuture fore the adole
This thesis answers the question whether opt-outs cause Danish political actors to lose Political Capital at the EU-level. In order to do this, Political Capital Theory is developed to fit a European Union context. The theory is then applied to data gathered from Danish political actors and other actors with great experience from the EU. From this, within the premises set by this thesis, it is pos
We wanted to use this paper to something important, something real that someone needs and wants to read. After having sent a request to all social services in the City of Malmö, we had contact with a section that had an idea that we would look at their collaboration. This study concerns how collaboration may look like and how it might change to achieve results. Social Services exist to help the c
The purpose of the essay is to examine explanations offered by both police and social workers for street robbery committed by juveniles. Our conclusions are based on the findings from a series of semi structured qualative interwievs conducted with social workers and police from Landskrona and Malmö. These findings have been analyzed using hypotheses suggested by Merton´s anomie/strain theory and H
Title: Configuring the storage and return flow processes of reusable packaging for battery cells: A design science study of a global battery cell manufacturer Author: Linnea Sjöberg Supervisor: Joakim Kembro, Division of Engineering Logistics, Faculty of Engineering, Lund University. Problem Description: As reusable packaging is becoming increasingly popular, the already existing warehouses need t
Uppsatsen analyserar kollektivavtalstäckningen och arbetsvillkoren inom ridsporten i Sverige, en sektor där arbetsförhållanden ofta präglas av långa arbetsdagar, obetald övertid och osäkra anställningar. Sverige har generellt en hög kollektivavtalstäckning, men hästnäringen utgör ett tydligt undantag. Enligt undersökningen är kollektivavtalstäckningen hög bland ridskolor, där ca 91 % av verksamhetThis thesis analyzes collective agreement coverage and working conditions in the Swedish equestrian sector, a field often characterized by long working hours, unpaid overtime, and insecure employment arrangements. While Sweden generally has high levels of collective agreement coverage, the equestrian industry stands out as a notable exception. According to the study, collective agreement coverage
This study aims to investigate how girls within SiS special residential homes for youths are constructed in Swedish news media. The study is based on the social constructivist perspective and Yvonne Hirdman's gender theory. The theory choices have been made to make visible how words in news media construct both gender and the overall image of girls within SiS special residential homes for yout
This bachelor thesis explores the intersection of Christian identity and postmodern critique through the concept of profilicity and related concepts. By examining the perspectives of theologians and philosophers, particularly with the help of the works of Medi Ann Volpe and her sources and synthesizing them with the works of Hans-Georg Moeller and Paul J. D’Ambrosio and their sources, various conc
