We present multiple-epoch radial-velocity observations for 104 stars in a field of the intermediate-age open cluster IC 4651 to . Only 13 stars (13%) of the full sample are field stars. From the 44 single member stars we find a mean radial velocity of , and the 12 single red-giant members yield a true radial-velocity dispersion of . Of the 19 giant members, 7 (37%) are spectroscopic binaries with
Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. Treatment alternatives have therefore been developed since the early 1980s to reduce the environmental impacts of peat mining. New, efficient methods suc
Popular Abstract in Swedish Sammanfattning Teknik är alltid skapad för en förväntad brukare i ett antaget sammanhang. Inom kommersiell luftfart är dessa antaganden när det gäller design tydliga. Såväl besättning som utrustning är certifierad för en viss typ av operationer i enlighet med flygplanets drifthandbok. Trots denna genomtänkta definition av användare i sitt sammanhang händer det ändå attAbstract Technology is always designed for an assumed user in an assumed context. In commercial aviation, these design assumptions are clearly spelt out in that both crew and equipment are certificated for a specific operation as stated in the aircraft flight manual. Despite this well defined user context, the designed-for and the real contexts often differ enough so that adaptations of working p
This thesis deals with students' constructions of mathematical knowledge in the case of fractions from a radical constructivist perspective. Fractions are the first more abstracted mathematics met by students. Even if they have a rich experience of sharing and partitioning things in their everyday life dealing with fractions often give rise to difficulties in school. The thesis consists of two p
The first essay examines the outcome in a competitive private pension market characterised by adverse selection. In addition to using the private pension market, the consumers can save in a bequeathable asset. Assuming two types of agents and using the Coalition Proof Equilibrium with Private Information we show that the outcome in the private pension market may be separating or pooling. A separat
Popular Abstract in Swedish Avhandlingen kretsar kring centralbankens möjligheter att kontrollera inflationstakten. Under senare tid har mycket forskning ägnats åt att analysera och utvärdera de institutionella förutsättningarna för centralbanker, såväl avseende graden av oberoende som vilka mål penningpolitiken bör inriktas mot; exempelvis direkta inflationsmål versus användandet av indirekta målAfter an introductory chapter, the hypothesis is made in chapter two: that central bank power to control the rate of inflation rests on the bank’s ability to achieve a role as a focal point for inflation. Inflation is a measure of changes in the general price level, the price level is an index of individual prices, and to predict future price levels is thus to predict future prices on individual i
Synovial sarcoma is an aggressive soft-tissue tumor that accounts for up to 10% of soft-tissue sarcomas. Cytogenetically, synovial sarcoma is characterized by the t(X;18)(p11;q11), found in more than 95% of the tumors. This translocation results in rearrangements of the SYT gene in 18q11 and one of the SSX1, SSX2, or SSX4 genes in Xp11, creating a SYT/SSX1, SYT/SSX2, or SYT/SSX4 chimeric gene. It
The social sciences have many different understandings of ‘normative power’, but in European Union (EU) studies normative power has three particular meanings. The first meaning of normative power is its emphasis on normative theory, that is, how we judge and justify truth claims in social science. The second meaning of normative power is as a form of power that is ideational rather than material o
Innan ett aktiebolag går i konkurs är det inte ovanligt att en större överföring görs, exempelvis till aktieägare. Aktiebolagslagen innehåller regler som kan användas mot bolag som företar illojala transaktioner mot borgenärer. En återbäringstalan av olovlig värdeöverföring är ofta komplex och ekonomiskt tung då omfattande utredningar av bolaget krävs. Konkurslagens återvinningsregler, framföralltBefore a public company goes bankrupt, it is not uncommon that a large transfer is made, for example, to the shareholders. The Limited Company Act i.a. Company Act contains rules that can be used against companies who undertake unlawful transactions from their creditors. A repayment claim of an unlawful transfer is often complex and economically heavy, because major investigations of the company n
Uppsatsen syftar att undersöka förlikningsavtal vid hantverkstjänster och småhusentreprenad samt undersöka felbestämmelserna i 9 – 14 §§ konsu-menttjänstlagen (1985:716) (KtjL) och jämföra bestämmelserna om fel för hantverkstjänster med specialbestämmelserna om småhusentreprenad i 51 – 61 §§ KtjL. Den traditionella rättsdogmatiska metoden har använts för att uppfylla syftet med arbetet samt ge svaThe purpose of the thesis is to study conciliation agreements within repair and remodeling activities and constructions considering family dwellings as well as research the regulations of faults in the consumers services act 9 – 14 §§ and compare the rules applied on repair and remodeling activities with the special rules applied on family dwellings found in the consumers services act 51 – 61 §§.
Increasing CO₂ emission is considered as the main reason for global warming in the world. One of the reasons for producing CO₂ is using of fossil-based materials in the construction projects. This study intends to assess the using bio-based materials instead of fossil-based materials for the thermal insulation layer of the external walls and roofs. Another focus of this project is using green conc
Internationella adoptioner började att ske efter andra världskriget för att hjälpa föräldralösa barn i krigsdrabbade länder och ökade senare i antal i samband med Vietnamkriget och Koreakriget. Det handlade främst om barnlösa par i Europa och USA som genom adoption ville rädda ett barn från hemländernas fattigdom. Det har dock framkommit att barn blivit illegalt adopterade, det vill säga adoptioneInternational adoption developed after the Second World War as an aid for orphaned children in war-torn countries and later on increased in numbers following the Vietnam War and the Korean War. The majority of adoptions concerned childless couples in Europe and the United States who through adoption wanted to save the child from poverty in its home country. International adoptions have however bee
In Sweden the Sami people is a national minority of indigenous people. Traditionally they are living in northern Sweden but can be found all over the country. The Church of Sweden has a long tradition of giving church services using the native Sami language in the Swedish part of Sapmi, the Sami people name of their land. The problem of recruiting Sami speaking clergy has always been great and dif
Background Today’s healthcare faces a transformation, driven by an ageing population and an over encumbered care and welfare sector. Self-care solutions based on emerging information and communication technologies make it possible for patients to monitor their medical conditions from home, without the direct assistance of healthcare professionals. Thereby time and resources within the healthc
In the last couple of decades in Sweden, there has been an adoption of “workfare”-oriented policy approaches to unemployment (as opposed to the former, less conditioned welfare-oriented ones). Consequently, labour market policies more and more have started to encompass the Social Services Department (in Swedish; “socialtjänsten”). In Scandinavia, active labour market policies are commonly referred
Molnens roll i klimatsystemet har studerats och deras påverkan på solens inverkan på jordens energibalans. Jordens albedo påverkar energibalansen genom att den påverkar hur mycket av solens instrålning som reflekteras eller absorberas. Moln påverkar jordens albedo och spelar därför en viktig roll i denna balans. Molnbildning sker till nära 100% i troposfären och där finns allt det vi kallar väder.The role of clouds in the climate system has been studied and their impact on the Sun's impact on the Earth's energy balance. The Earth's albedo affects the energy balance by influencing how much of the Sun’s radiation is reflected or absorbed. Clouds affect the Earth's albedo and therefore play an important role in this balance. Cloud formation occurs almost 100% in the tropospher

The thesis is carried out at Scania’s production unit Engine Assembly where engines are assembled, tested and painted. All engines proceed through a standard test procedure while some of the engines also proceed through special test procedures carried out in the ”Audit Area”. The
Wetlands are valuable ecosystems, and assets for human life, that must be regularly monitored, starting with accurately mapping their location and extent. However, an updated national inventory of wetlands is needed. The availability of multi-source data, and advanced machine learning algorithms in Google Earth Engine (GEE) offers excellent opportunities to map wetlands on a country-wide scale. Th
The aim of this project was to examine if it is feasible to develop and apply a reuse concept regarding clean in place (CIP) processes. The concept is based on different topics such as lim-itation, structure, future and reliability. Three CIP processes were chosen to represent the wide variety of cleaning processes available to the food and pharmaceutical industries, Single use Food, Recovery Food
