Drell-Yan process in pA collisions : Path-integral treatment of coherence effects

In this work, we investigate production of Drell-Yan (DY) pairs in proton-nucleus collisions in kinematic regions where the corresponding coherence length does not exceed the nuclear radius, RA, and the quantum coherence effects should be treated with special care. The results for the nucleus-to-nucleon production ratio available in the literature so far are usually based on the assumption of a ve

A Meta-Analysis of Bottom-Up Ex-Ante Energy Efficiency Policy Evaluation Studies

Energy efficiency ex-ante policy evaluation is commonly, but not exclusively, concerned with the simulation and modelling of policy instruments and resulting technological change. Using the residential sector as case study, the paper provides a meta-analysis of models and modelling exercises and scrutinise their relevance for the field of energy efficiency policy evaluation. The methodology of stu

Skönlitteratur som folkbibliotekets instrument : förväntade effekter på samhället omkring år 1905-1911

Which expectations did leading debaters place on fiction as an instrument in achieving societal changes hoped for by introducing the Public library? How can the value of fiction be described in relation to the mission of the Public library, according to these moulders of public opinion? Place and timeframe for this thesis is Sweden around the years 1905-1912 (period of formation of the Public libr

Arbetsgivares möjlighet att avsluta en anställning som konsekvens av uttalanden på sociala medier

Den här uppsatsen har syftet att utreda en arbetsgivares möjlighet att säga upp en anställd om denne beter sig olämpligt på privata sociala medier. I Sverige finns ett långtgående skydd för anställningen, och en ännu starkare yttrandefrihet. I kontrast har anställda en lojalitetsplikt mot sin arbetsgivare, och är skyldiga att inte skada arbetsgivaren ens på sin fritid. I uppsatsen undersöks om detThis essay aims to investigate an employer's ability to terminate an employment if the employee is behaving inappropriate on private social media. Sweden has a strong protection of the employment, and an even stronger protection of the freedom of speech. On the other hand, employees have a duty to be loyal to their employer, and are obliged not to harm the employer even in their spare time. Th

Evaluation of enhanced absorption of carbon dioxide using carbonic anhydrase in aqueous solutions of 2-amino-2-methyl-1-propanol

The use of carbonic anhydrase (CA) as a catalyst for bicarbonate formation in amine solutions has shown the potential to increase the absorption rate of CO2, thus potentially reducing capital cost of a CO2 capture plant, as the size of equipment can be reduced. On another approach, it could replace part of the amine to offer lower environmental impact. In this work, the catalytic effect of CA on t

Uncertainty quantification for nonlinear solid mechanics using reduced order models with Gaussian process regression

Uncertainty quantification (UQ) tasks, such as sensitivity analysis and parameter estimation, entail a huge computational complexity when dealing with input-output maps involving the solution of nonlinear differential problems, because of the need to query expensive numerical solvers repeatedly. Projection-based reduced order models (ROMs), such as the Galerkin-reduced basis (RB) method, have been

Solidified water at room temperature hosting tailored fluidic channels by using highly anisotropic cellulose nanofibrils

Highly anisotropic cellulose nanofibrils can solidify liquid water, creating self-supporting structures by incorporating a tiny number of fibrils. These fibrillar hydrogels can contain as much as 99.99 wt% water. The structure and mechanical properties of fibrillar networks have so far not been completely understood, nor how they solidify the bulk water at such low particle concentrations. In this

‘Why not make films for New York?’ : The interaction between cultural, political and commercial perspectives in Swedish Film Policy 1963-2013

During the last two decades or so, film support, film policy and the public financing of audiovisual production in Scandinavia and particularly Sweden have undergone extensive transformation. In diverse ways, these changes can be seen as responses to globalization, to increased sub-national regional independence as well as to the emerging idea of nurturing ‘creative industries’ taking hold. They m

Optical Imaging for Nanowire Mechanics

In this work, we present a stroboscopic detection technique for the study of oscillating nanoscale objects. This optical read-out gives a position accuracy better than 1 nm which is a fraction of both the diffraction limit and the pixel size. The advantage of this stroboscopic method compared to conventional time-averaging techniques, is the time-resolution it provides as well as being non-invasiv

Fluorine in the Solar Neighborhood : The Need for Several Cosmic Sources

The cosmic origin of fluorine is still not well constrained. Several nucleosynthetic channels at different phases of stellar evolution have been suggested, but these must be constrained by observations. For this, the fluorine abundance trend with metallicity spanning a wide range is required. Our aim is to determine stellar abundances of fluorine for. We determine the abundances from HF lines in i

The use of routine ultrasound in pregnancy : with special reference to normal and abnormal foetal growth, information and informed choice and the womens' experiences of the prenatal diagnostic aspects

The development of real-time ultrasound in the 1970's made indelible inpact on antenatal care. Assessing foetal growth and detecting deviations from normal in both growth and foetal anatomy became fesible. Expectant parents could also 'see' their foetus. Normal foetal growth parameters at term were consituted and selected parameters from the second trimester were evaluated in the detection of chro

Immunocytochemical localisation of neuronal nitric oxide synthase in developing and transplanted rabbit retinas

Nitric oxide (NO) acts as a modulator of neuronal transmission in mature neuronal systems, including the retina. Recently, NO has also been suggested to have a trophic function during development. We examined immunocytochemically the distribution of NO-producing cells in developing and transplanted rabbit retinas. An antibody detecting the neuronal isoform of its biosynthetic enzyme, nitric oxide

Heritable responses to combined effects of heat stress and ivermectin in the yellow dung fly

In current times of global change, several sources of stress such as contaminants and high temperatures may act synergistically. The extent to which organisms persist in stressful conditions will depend on the fitness consequences of multiple simultaneously acting stressors and the genetic basis of compensatory genetic responses. Ivermectin is an antiparasitic drug used in livestock that is excret

Product design and development of a movable and removable plate

This project was performed in collaboration with ArjoHuntleigh’s Innovation Centre in Malmö, Sweden, from January 2014 to June 2014. The objective of the thesis was to design and develop a movable or removable plate/shelf. The Project has been carried out by using the methodology described in the book “Product development and Design” by Ulrich and Eppinger. The methodology has been modified to fi

Bestämning av kvartshalt i sandprov : metodutveckling med OSL-, SEM- och EDS- analys

Kvarts är ett av de vanligaste mineralen i jordskorpan, både i sediment och i bergarter. Halten kvarts i sediment är intressant vid bedömning av bl.a. mognadsgraden. Ett sediments mognadsgrad kan användas vid tolkning av dess historia, vilket är till nytta vid t.ex. rekonstruktion av paleomiljöer. Geologiska institutionen vid Lunds universitet, har efterfrågat metoder för bedömning av kvartshaltenQuartz is one of the most common minerals on Earth and is found in both lose sediment, sedimentary rock and bedrock. The maturity grade of sediments can be determined by the amount of quartz it contains. This is used when interpreting the sediments’ geological history and reconstructing paleoenvironments. The purpose of this thesis is to analyze and develop methods for determining the quartz conte

Leder Lean till Green?

In this thesis, a qualitative comparative case study has been conducted in five production companies. This has been made to get an understanding of how companies work with Lean and environmental management. Four interviews were conducted and two survey responses were received and there were eight open-ended questions where respondents were relatively free to talk about their experiences. The quest

Light interaction with nano-materials

"There is a crack in everything. That's how light gets in." With two simple sentences the famous poet Leonard Cohen describes his perception on how light interacts with matter. This thesis work will try to give a more precise and detailed description of the interaction between light and nano-materials that maybe is going to lose some of the magic that poetry has but this will be com

Otukt mot naturen, vems natur? Om avkriminaliseringen av homosexualiteten

Svensk sammanfattning I och med inträdandet av en avkriminalisering beträffande homosexualiteten i juli 1944 kom homosexuella handlingar att inte längre ses som något brottsligt. Kampen mot jämställdhet slutade inte där, det skulle dröja fram till 1979 innan homosexualiteten ströks ur Socialstyrelsens listor över sjukdomsbegrepp. Idag har homosexuella bland annat rätt att ingå äktenskap och adoptEngelsk sammanfattning Due to the entry into force for a decriminalization regarding homosexuality in July 1944, homosexual activities were not considered as something criminal anymore. The struggle towards a more equal society did not end there. It took until 1979 before homosexuality was removed from the National Board of Health and Welfare (Socialstyrelsens) register of illnesses. Today, homos

Barn som bevittnar våld i nära relationer,tillkomst, ansvar och tillämpning

Det svenska samhället har under längre tid sett ut så att skyddet för familjelivet, den privata sfären, vägt tyngre än ett offentligrättsligt styrande. Den rättsliga utvecklingen har dock under tid varit föränderlig och lagstiftaren har vägt in parametrar som att barn kan vara utsatta i familjelivet där de som skall ta hand om dem är de som utsätter barnen för skadliga handlingar. Enligt FN:s barnSwedish society has for some time looked to the protection of family life, private life, weighed heavier than a public ruling. The legal development, however, has been changing over time, and the legislature has weighed in parameters that children can be exposed in family life where those who must care for them are those who expose children to harmful acts. According to the UNCRC, the child's

Giftfri förskola i Hässleholms kommun. Inventering av fyra förskolor – nuläge och åtgärder

Material och produkter som kan innehålla hälsofarliga ämnen förekommer på förskolor i Hässleholms kommun. Bristande kunskap och rutiner bidrar även till barns exponering för dessa ämnen. Det är av vikt att man arbetar långsiktigt för giftfria förskolor. Åtgärder finns, och en hel del kan göras omgående för att minimera problemet. Användningen av kemikalier har ökat markant de senaste decennierna.During the last decades the production and consumption of chemicals has increased dramatically. We know that some chemicals are hazardous for humans and the environment but for most of them our knowledge is limited. Children are very sensitive to hazardous substances compared to adults because of their undeveloped bodies and different behavior. Due to lacking knowledge and regulation of chemicals
