Quality is one of the most important factors when it comes to consumers’ purchase decisions. Food products are expected to fulfill certain expectations and their quality must stay stable and consistent throughout the shelf life. To constantly sustain and improve the quality of their products is thus the ambition of the food industry and was the concern of this project. The influence of a changed h

Studies of the Milky Way including how it formed and evolved through time are the key to understanding how other galaxies behave. The Milky Way is the most convenient galaxy to study, because the close proximity of stars means astronomers can collect precise spectral and dynamical data from individual stars. By combining the chemical and dynamical aspects, it is possible to pinpoint stars which ha

När Tycho Brahe på 1500-talet stod i sin Stjärneborg på ön Ven utanför Landskrona och kartlagde stjärnhimlens rörelser utövade han vad vi i dag kallar för astrometri: att mäta himlakropparnas positioner och rörelser. I ett historiskt skede skulle precisionen i Tychos mätningar komma att knyta ihop astronomin med fysik för första gången. Johannes Kepler, Tychos medhjälpare och efterträdare, kunde mThe all-sky survey of Gaia will generate vast amounts of astrometric data, in which there are expected to be thousands of planets found. Finding a system of $n_\textup{p}$ planets requires fitting of a total $5+7n_\textup{p}$ parameters: five astrometric and seven Keplerian parameters for every planet. The problem is thus highly non-linear and computationally prohibitive. After exploiting the line

Mängden kostnadsfria kartor som finns tillgängliga genom nedladdningstjänster på internet kommer enligt trenden i samhället att öka. I och med det kommer även antalet nedladdningstjänster öka. Att fler kan tillgå kostnadsfria kartor kommer troligtvis leda till nya produkter och tjänster som kan öka effektiviteten för både privat och offentlig sektor. Nya tjänster kan även leda till bättre service,There are currently numerous web services that provide the user with the opportunity to download geodata. These services are often different regarding what type of data they provide and the way they distribute the data. Another aspect that differs between these services is if the download of geodata is free of charge (open) or subject to a fee. There is currently a trend in the society striving to

This research project provides insights in how knowledge workers make sense of their context of job insecurity in terms of motivation and aims to develop a theoretical understanding on motivation from a more conceptual point of view. There are several universally acknowledged motivation theories that claim to explain what motivates people. According to these theories, the job-threatening situation

Byggbranschen kritiseras för sitt konservativa tänkande och ineffektivitet. Generellt sett har branschen låg lönsamhet med små marginaler. För att uppnå lönsamhet i ett byggprojekt krävs styrning mot uppsatta projektmål. Mål och vinstmarginaler nås genom ekonomisk styrning. Begreppet ekonomistyrning omfattar alla aktiviteter från planering till uppföljning och avstämning som görs för att upptäcka The construction industry is criticized for its conservative orientation and inefficiency. The industry has a low profitability with small margins. To make a construction project profitable it requires steering towards established project goals. Goals and profit margins are achieved through cost control. The concept of cost control covers all activities from planning to monitoring and reconciliati

This thesis is a combined critical, biographical, and bibliographical study of American poet Frank Stanford (1948-1978). A prodigious, prolific poet's poet, Stanford is a long-underappreciated artist whose unwavering legacy, in recent years, has grown to be an undeniable force in contemporary American poetry. Stanford was an adoptee, and this study investigates his preoccupation with his loss

Molecular imaging techniques have become an essential tool for cancer diagnosis. They have the potential to detect cancer at early stages and thus, they can change the outcome of the disease and patient prognosis. Magnetic resonance imaging (MRI) has arisen as one of the most promising imaging methods used for the screening of soft tumor tissues such as breast cancer. However, the specificity of M

Förevarande uppsats behandlar de argument och ställningstaganden som ligger bakom lagstiftarens beslut beträffande assisterad befruktning i allmänhet, och surrogatmoderskap i synnerhet. Den alternativa familjebildningen och den assisterade befruktningens historia går långt tillbaka i tiden, men började på allvar regleras på 1980-talet, då inseminationsutredningen grundligt utredde frågan. VariatThe thesis at hand deals with the arguments and positions underlying the legislators decisions concerning Assisted Reproductive Technology (ART) in general, and surrogate motherhood in particular. The history of alternative ways to start a family, and ART goes far back. However, it only really began to be the subject of regulation in the 1980s, when the government issued an investigation, to thoro

När man tar en medicin är det viktigt att man tar rätt dos. Tar man för liten dos uteblir den önskade terapeutiska effekten och tar man för stor dos kan bieffekterna bli allvarliga. Skillnaden mellan terapeutisk och giftig dos kallas terapeutiskt fönster. Om det terapeutiska fönstret är snävt kan man behöva ta små doser ofta för att en säker och effektiv koncentration av läkemedlet i kroppen underThe purpose of this project was to develop and test lipase-based in vitro release (IVR) assays for model and active pharmaceutical ingredients (API) entrapped in lipid formulations based on mixtures of phosphatidylcholine (PC) and glycerol dioleate (GDO). Two dyes, Fluorescein disodium salt and Patent Blue V sodium salt, functioning as model drug compounds, were investigated separately in the PC/G

Vindkraftens utbyggnad kommer leda till att det i framtiden kommer ställas högre krav på nedstyrning av den aktiva effekten i vindkraftsanläggningar. Denna rapport tar upp hur elproduktionen påverkas vid nedstyrning. Det är inte alltid självklart hur en anläggning påverkas då det är faktorer som turbinlayout, vindriktning och vindhastighet som spelar in. För att kunna modellera nedreglering av deThe expansion of wind power will lead to higher demands on downward regulation of active power in wind power plants. This report treats how the production of electricity is affected by downward regulation. It is not trivial how a wind power plant reacts since factors like turbine layout, wind direction and wind speed have an impact. To be able to model downward regulation of the active power the w

Syftet med studien är att få en inblick i varför väderskydd inte används i den utsträckning som rekommenderas med tanke på fuktsäkerheten. Att intervjua personer i projekt med väderskydd och även elementskyddade väderskydd av olika karaktär görs för att undersöka varför dessa beslut tas samt hur väderskyddet hanteras i ett upphandlingsskede. Genom att undersöka fallprojekt som platschefer är iblan

The process of evaluating early stage start-ups is often considered a great challenge from the perspective of a business angel. The main concern of this study is to investigate the methods that business angels use to evaluate early stage start-ups and which, if any, methods are used for the final valuation. The lack of previous theoretical research on the valuation methods of business angels and e

The thesis serves to understand how women create gender identities and constructions of the world within the Swedish blogosphere. The research is based on a Qualitative Critical Multimodal Discourse Analysis of the language and imagery used in the Swedish blogosphere.The study of the Swedish blogosphere reveals how “The new woman” is internally conflicted due to old gender stereotypes and her purs

Wearable electronics is the technology on everybody’s lips as of 2015. Different companies release smartwatches almost once a month. One of Jayway Syd AB’s clients is the trading bank Nordnet and together they saw an opportunity with trading in combination with smartwatches. This master’s thesis describes the process in which the possibilities around smartwatches and trading were explored with the

Today there are still single family houses with direct electric heating systems, even though this is an expensive and inefficient way of heating a house. It is common to install an air-to-air heat pump that requires less electricity to produce the same amount of heat as a direct electricity heating system. These heat pumps do not produce any energy for domestic hot water since the water is heated

Psykiskt störda lagöverträdare har särbehandlats sedan antikens dagar. I de flesta länder i världen finns det än idag ett krav på att en person ska vara tillräknelig för att kunna dömas till ansvar för brott. Om man är tillräknelig betyder det att man vet vad man gör och att man har förmåga att kontrollera sina gärningar, det vill säga att man har ansvarsförmåga. I Sverige finns det inget krav på Mentally disordered offenders have always been treated differently by the criminal justice system. In most countries the law requires that the accused is sane to be considered accountable for his or her actions. Accountability, in this context, means that you know what you are doing and that you are able to control your actions. In Sweden there is no requirement that the accused is sane to be cons
