Popular Abstract in Swedish Resultaten som presenteras i denna doktorsavhandling visar att det går att spara stora mängder energi genom att använda samma typ av värmeväxlare, som normalt används i bilar och lastbilar, i livsmedelsbutikernas kyldiskar. För att hålla maten kall när den ligger ute i butiken cirkuleras en kyld luftström runt i kyldiskarna. Denna kyls i en så kallad värmeväxlare som Provisions are stored and displayed in supermarkets and grocery stores, at a temperature lower than the ambient, in display cabinets, which are responsible for a significant amount of the energy use in this sector. During the 1990s, major changes in the regulations governing the use of synthetic refrigerants took place in Sweden. This resulted in many refrigeration systems being converted to syste

Att investera i aktier på värdepappersmarknaden blir alltmer vanligt förekommande vilket resulterar i ett ökat behov av information för marknadens aktörer. Reglerna om prospekt syftar huvudsakligen till att skydda en investerare från felaktig information avseende ett investeringsobjekt. När ett bolag erbjuder överlåtbara värdepapper till allmänheten eller ansöker om upptagande till handel på en reInvesting in shares on the securities market is increasingly common occurring resulting in an enlarged need of information for the market participants. The Prospectus Rules essentially seek to protect an investor from misinformation regarding an investment object. When a company offers transferable securities to the public or admission to trading on a regulated market, this company is namely oblig

Popular Abstract in Swedish Denna avhandling behandlar epitaxiell växt av nanotrådar i III-V halvledarmaterial, i vilken guldpartiklar använts som frö, samt design av tredimensionella mer avancerade förgrenade strukturer baserade på dessa trådar. Växten utfördes via så kallad ?MetallOrganic Vapour Phase Epitaxy? (MOVPE), i vilken prekursormolekylerna till halvledarmaterialens komponenter tillförs This thesis describes the epitaxial growth of III-V semiconductor nanowires using Au seed particles, and the design of more complex three-dimensional branched structures from these wires. Growth was performed by metallorganic vapour phase epitaxy, in which precursor molecules for the semiconductor material components are introduced in a low-pressure vapour. Nanowires grow epitaxially (with control

Det finns ett samhällsintresse att verksamheter i offentlig regi drivs så kostnadseffektivt som möjligt. När verksamheten har ett minimikrav på bemanning som krävs för att driva verksamheten, kan arbetsuppgifter inte överföras på andra anställda vid någons frånvaro. Den frånvarande måste ersättas. Detta innebär att många verksamheter drivs med viss ”övertalighet”. Syftet med denna fallstudie var aThere is a public interest that activities operated by the public sector are run as cost effectively as possible. When an organization has a minimum requirement of staffing required to run its activity, work cannot just be transferred to other employees at someone's absence. The absentee must be replaced. This means that many organizations are run with some "redundancy". The purpose

Fault detection systems come in a variety of formats and are used in many different types of machines and industries. They can be used to perform fast and accurate detection, classification and analysis. The need for user interaction can be decreased and by that the general level of automation can be increased. This project has been conducted together with B\&R Automation and Imogo. B&R

The bond strength between concrete and corroded steel reinforcement bar is one of the main responsible factors that affect the ultimate load-carrying capacity of reinforced concrete (RC) structures. Therefore, the prediction of accurate bond strength has become an important parameter for the safety measurements of RC structures. However, the analytical models are not enough to estimate the bond st

Historiska bosättningar är av stort intresse eftersom de kan hjälpa oss att nå en förståelse om vårt förflutna och våra kulturella rötter. Tack vare den teknologiska utvecklingen är det nu enklare att lokalisera vissa av de historiska bosättningar som blivit översvämmade genom att kartlägga havsbotten. Forskning om översvämmade mesolitiska boplatser har lett till att det finns utvecklade hypoteserHistoric settlements are of great interest since they play a role in understanding our past and our cultural roots. The development of technology now makes it easier to map the seafloor and locate submerged settlements. Finding submerged Mesolithic settlements has led to hypotheses being made on what characteristics to look out for which could suggest Mesolithic settlement locations. This study fo

Standardmodellen är det teoretiska ramverk som beskriver partikelväxelverkningar på subatomär nivå. För att bekräfta teorins förutsägelser behöver experimentella data samlas in. I partikelfysik kan information om hur partiklar produceras och växelverkar med varandra erhållas genom att accelerara partiklar till höga energier och sedan låta dem kollidera. Detta är skälet att partikelkolliderar

Problem: There are strong forces from for instance politicians, who want to allow third party access to the district heating market, as has already been done in the electricity and gas markets. But what would be the consequences of a third party access to the district heating market? Will it create a competitive market, and will it be able to put any pressure on the prices? What will be the conseq

The purpose of our essay was to examine what treatment women have had, who in their teenage years had eating disorders, how they have experienced this treatment and how they live today. Our central questions were; what was their experience of the treatment, how are their lives today, has the eating disorder and the treatment affected how the women live today and what kind of treatments are there?

Osteoarthritis (OA) is the most common arthritic disease in the world, leading to debilitating pain and destruction of joint tissues. While pain is the hallmark symptom of osteoarthritis, clear associations between pain and disease processes involved in joint deterioration are lacking. OA pain is multifactorial and may arise from multiple distinct or concurrent mechanisms, and may thus present as

IntroductionWithin the concept of waste water treatment the opportunity of integrating pervaporation has been widely recognised. Applying pervaporation, generally two different process designs can be applied – vacuum and sweep gas pervaporation. Previous research focused primarily exclusive on one of this process designs. In this study the benchmarks of vacuum and sweep gas pervaporation are defin

This thesis concerns early medieval dress brooches from urban and rural sites in South West Scania. The purpose is to investigate similarities and differences between urban and rural sites as well as between the rural places in particular. The main research questions concern the reasons for the similarities and differences, what connections and contact areas are observable according to the dress b
