Context. NGC 1851 is one of several globular clusters for which multiple stellar populations of the subgiant branch have been clearly identified and a difference in metallicity detected. A crucial piece of information on the formation history of this cluster can be provided by the sum of A(C+N+O) abundances. However, these values have lacked a general consensus thus far. The separation of the subg

Rubber materials, preferably referred to as elastomers, are used in a wide variety of engineering applications, thanks to their unique properties and characteristics. Fluid channels between the plates of Alfa Laval’s heat exchangers are sealed with different types of elastomers, called gaskets. Gaskets are exposed to both chemical, physical and mechanical stresses during their lifetime, affecting

Information and Communication Technology (ICT) is one of the fastest growing sectors in the world in business sales, energy consumption as well as waste streams. It is pressured for conflict minerals, unsustainable raw material use and hazardous substances, and must quickly respond to these challenges. One way to drive this change is sustainable procurement, with environmental and social minimum a

The rapid development of digitization in recent years has meant enormous opportunities for improvement and efficiency of various activities within a company. Furthermore, the digital era has meant that digital tools are becoming more common for additional sectors and businesses. Yet, the construction industry seems to lack in this development. There is a general consensus that the construction ind

Plaster som används för dagligt bruk består till stor del av fossila ämnen. Med ökad efterfrågan och produktion för varje år, är en hållbar utveckling för plaster en växande utmaning. Ett av de stora problemen är förbrukningen av de icke förnyelsebara fossila källorna, vilket medför att förr eller senare behövs alternativ till de konventionella plasterna. Med detta problem i åtanke, så fokuserar dPlastics for everyday use are made from fossile resources. With the demand for plastics increasing every year, a sustainable development for plastic products is a growing challenge. A major issue is the depletion of the non-renewable fossile resources, which means that sooner or later alternatives to the conventional plastics are needed. With this problem in mind, this work focuses on the developm

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease with neither a known cause nor an available cure. With disease progression, toxic protein aggregates form in the brain, leading to the loss of the upper and lower motor neurons. While circulating bone marrow-derived inflammatory cells have not been shown to cross the blood brain barrier, changes in their number and comp

Abstract Author: Ella-Kari Meyrell Title: Strategy for welfare - a discourse analytical study of culture in health, social care and school organizations Supervisor: Håkan Jönson Assessor: Torbjörn Hjort The aim of this study was to examine how culture (as “the arts”) is constructed as a strategy in welfare work. The empirical material was based upon 160 articles from Swedish printed and web base

Within the Renewable Energy Directive, the European Union has embedded sustainability criteria, addressing sustainable biofuels. Due to criticism, the sustainability criteria have been re-examined by the EU in the light of Indirect Land Use Change (ILUC). This thesis focuses on the sustainability understanding of the EU on biofuels, through assessing the sustainability criteria in the realms of su

Drönare är obemannade luftfartyg som vanligtvis fjärrstyrs från marken. Från att ursprungligen ha brukats i militär verksamhet har drönare de senaste åren börjat spridas till civila näringsverksamheter, t.ex. inspektion av fastigheter. Genom HFD 2016 ref. 71 I fastställde Högsta förvaltningsdomstolen att kameror monterade på drönare är övervakningskameror, och därför är tillståndspliktiga enligt kDrones are unmanned aerial vehicles that are controlled from the ground. From having been used at first solely for military purposes, they have spread to civil businesses over the last few years, for example to help at property inspections. Through HFD 2016 ref. 71 I it was decided that cameras mounted on drones are considered as surveillance cameras and require permits according to the camera sur

Pharmacokinetics is the study of how drugs are absorbed and distributed in the body and is used by pharmacists to ensure that they prescribe the appropriate dosage of medicine. The process used to determine the drug concentration in the body when medicine is prescribed is ADME; absorption, distribution, metabolism and excretion. The body is viewed as consisting of compartments between which a drug

Med ett politiskt parti anklagat för fascism i riksdagen, och nynazister marscherande på gatorna är frågor om demokrati och frihet viktigare än någonsin. Var bör yttrandefrihetens gränser dras? Bör den överhuvudtaget begränsas? Syftet med den här uppsatsen är att utforska en möjlig lösning till de problem som dagens demokrati står inför. Det här åstadkoms genom en konstruktion av ett konceptuellt With a political party accused of fascism in the Swedish parliament and neo-nazis marching in the streets, questions of democracy and freedom of expression are as important as ever. Where to draw the boundaries of the freedom of expression? Why have, or limit, such freedoms in the first place? The purpose of this thesis is to investigate a possible solution to the problems facing contemporary demo

Denna studie undersöker om maskininlärning kan användas för att förbättra bedömningen av rehabiliteringsövningar. Resultatet visade att metoden har potential, men att det krävs ytterligare studier för att utveckla en användbar lösning. Rehabiliteringsövningar är en viktig del av återhämtningen från skador och för att den ska bli korrekt krävs hjälp från en fysioterapeut. Fysioterapeuten guidar pa

Purpose – The road freight industry is becoming more and more complex. An increasing number of actors participating in the transport process has been highlighted. Simultaneously, transport constellations become more fragmented. With transport as feature of the product-offer, sending companies face new challenges. While transport has as part of the product offer influence on the customer satisfacti

Syftet med denna uppsats är att analysera Fackföreningslagen och dess potentiella konsekvenser för fackföreningars föreningsfrihet i den kambodjanska textilindustrin. Utöver detta analyseras lagen i förhållande till redan befintlig nationell lagstiftning samt i relation till internationell rätt rörande föreningsfrihet. Majoriteten av Fackföreningslagens regleringar är oförenliga med internationeThe aim of the thesis is to elaborately analyse the Trade Union Law and its possible implications for trade unions’ right to freedom of association in the Cambodian garment industry. In addition, the law is evaluated in relation to already existing domestic law and in relation to international law regarding freedom of association. The majority of the Trade Union Law’s provisions are incompatible

It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. In this study the de

Minimizing changeover times are considered critical by manufacturing industries to decrease non value adding processes, while at the same time being able to respond to changing customer requirements quickly. It is a hard task to manage but in this case a critical part was identified within a package manufacturing machine. The goal was then to find out if this specific part could be redesigned to s

Genom att använda koldioxidinfångning som drivs av överskottsvärme på ett massabruk i sydvästra Sverige så kan mer än en tredjedel av de fossila utsläppen från hela pappers- och massaindustrin fångas in genom så kallade negativa utsläpp. Detta visar på hur snabbt Sveriges fossila utsläpp kan minska genom användning av koldioxidinfångning. På ett massabruk används trä som den huvudsakliga råvaranAs the atmospheric carbon dioxide keeps increasing, bioenergy with carbon capture and storage (BECCS) is getting increased attention as a measure to reduce the emissions of carbon dioxide. It is especially interesting in Sweden where the extensive paper and pulp industry constitutes point sources of biogenic carbon dioxide. As carbon capture requires energy, it is important to investigate the oppo

In this study, we modeled the aerosol particle formation along air mass trajectories arriving at the remote Arctic research stations Gruvebadet (67 m a.s.l.) and Zeppelin (474 m a.s.l.), Ny-Ålesund, during May 2018. The aim of this study was to improve our understanding of processes governing secondary aerosol formation in remote Arctic marine environments. We run the Lagrangian chemistry transpor

Inkludera biodiversitet i livscykelanalyser - Hur fungerar det? Biodiversitet är ett begrepp som innefattar mångfalden av arter, ekosystem och gener. Ju större mångfald desto bättre. Hur kan man koppla mångfald i naturen till produktion av olika biodrivmedel och varför är detta viktigt? Att världens befolkning står för en stor utmaning att minska utsläppen av växthusgaser för att dämpa den globaAnalysing the environmental impact connected to biofuels has lately become more important due to the European Commission’s energy and climate target for 2020. These targets includes among others, 20 % reduction of greenhouse emissions and 20 % energy efficiency. One important solution for achieving this climate target is to increase the renewable fuel sector. In order to decide which biofuels that
