The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.

Background: Home health care means that patients receive care in their home. Äldrevårdsenheten in Uppsala County treats people, over 65 years, in the patient's home and because of the fact that the quality of care from the patient´s perspective not have been studied previously, this study as part of the quality control of the business.Aim: The aim of this study was to investigate how patients, and family members, who receive care within the Äldrevårdsenheten in Uppsala County experiencing the care provided in the home.Method: Interview study with qualitative analysis.Results: Patients who are cared for within the Elderly Care Unit in Uppsala County Council has a positive experience of home care. Being cared for in the home creates a sense of security and calm in the patients rather than the stress and fear of long waits in the emergency department and planning advice from medical appointments . In contrast, perceived lack of physicians in home care and accessibility to health care staff.Conclusion: In general, patients in the Elderly Care Unit in Uppsala County Council very pleased with the opportunity to the treatment they received at home. However, there are some weaknesses that need improvement. .

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

AbstractThe purpose of this study was to describe the post-operative care during the three first days for patients who have undergone colorectal surgery according to ERAS care programs with a focus on the variables nutrition, elimination, activity, type of analgesia and the number of hospital days documented in the patient record and patient log books. ERAS means "Early Recovery After Surgery" and the purpose of the health care program is to accelerate recovery after colorectal surgery. The study had a descriptive design and a quantitative approach, in which 51 patient records were included. Log books and patient records were reviewed postoperatively. According to the log books estimated most of the patients, who had documented, that they ate and drank very good or good.

Kommunikation förutsätter att vi har förmågan att förmedla ett budskap och förmågan att uppfatta ett budskap från andra och därmed får språket en stor betydelse för utveckling och lärande i skolan. Barn med språkstörning har svårt att göra sig förstådda via språklig kommunikation och på motsvarande sätt har de svårt att förstå. I tidigare studier görs jämförelser mellan olika förskolor och specialförskolor för barn med språkstörning. Denna studie fokuserar på skoltid för barn med språkstörning.Syftet med studien är att beskriva några stödpersoners syn på faktorer som styr placering av barn med språkstörning i olika undervisningsformer. Empirin består av fem semistrukturerade intervjuer.

The advancements of Internet have contributed to the expansion of social networks and new communities online where people are given an opportunity to get help and support. An important reason why people join these groups and organizations is to share their experiences, meet people in a similar situation and get support. Social media is nowadays an important part of our society. In this study, we will focus on investigating the interaction in closed communities online and blogs. The study aims to investigate whether social media and social networks online can be a support for young adults with cancer in the same way as physical meeting places.

The aim of the study was to do an analysis about the conceptions of units and unit con-version. Investigating the students´ attitudes towards their own mathematical ability and the students´ understanding of the conception of units..

As IT service departments in organisations are becoming more complex and customised, the indirect costs are increasing in relation to the total costs. The difficulty of fully estimating and identifying the spread of the cost in the IT service department is increasing. As a result, firms tend to budget the business unit as a total cost rather than as a spread of defined costs. In order to deal with this challenge an ABC calculation will be applied. The Time Driven ABC model will be conducted in OMX´s Servicedesk unit within the IT services.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Background: The district nurses profession has traditionally been health promotion. In order to find patients with excessive alcohol intake, district nurses use AUDIT. Research shows that health professionals find it difficult to face alcohol abusers in primary care. AIM: The aim is to describe how district nurses work with AUDIT. Method: Semi-structured interviews with six informants were carried out.

Våren 2011 beslutade Röda Korset i Sverige att sluta skicka skänkta kläder som bistånd till katastrofområden. Röda Korset ställdes nu inför frågan vad de ska göra med de skänkta klä-derna för att omvandla dem till en resurs.Uppdraget var att i samarbete med Zäntrumprojektet och Röda Korsets secondhandbutik Ku-pan förädla de skänkta kläderna på ett miljövänligt sätt. Tanken är att Zäntrumprojektet ska sy om de skänkta kläderna till nya produkter som sedan ska säljas i secondhandbutiken Kupan.Syftet med den här uppsatsen är att finna ett sätt att förädla de skänkta kläderna och skapa nya produkter av dem. Vidare ska de skänkta kläderna skapa bättre resurser till Röda Korset som de kan tillgodogöra sig i sitt välgörenhetsarbete. Produkterna ska vara skapade på ett sådant sätt att de avger minsta möjliga avfallsmängd, främjar hållbar utveckling samt är attraktiva för Röda Korsets secondhandbutiks kunder.

The main objective of this research was to study how increased arterial oxygenation by the use of Pulsed Inhaled Nitric-Oxide (PiNO) influenced the metabolic and cardiovascular parameters on horses undergoing acute abdominal surgery because of colic. The parameters blood lactate, blood glucose, pH and heart rate were evaluated before and during anesthesia and closely after recovery. The study showed that blood lactate concentrations decreased significantly during anaesthesia in horses treated with PiNO compared to non-treated horses. It was also seen that the lactate concentration decreased most in horses with the highest levels before PiNO treatment. Since enhanced oxygen extraction ratio was evident in the PiNO group, improved oxygen delivery to the tissue may be a possible explanation for the improved situation.

The purpose of this paper was to examine how clients on the unit for adults at Södemalms district administration (Stockholm, Sweden) with severe mental illness and substance abuse differs from other clients with substance abuse at the baseline and at follow-up one year later. We have used a quantitative method and analyzed material from ASI-interviews performed at the adult drug abuse unit at Södermalm during the time period 2002-2010. At the baseline the clients with substance abuse and co-occurring severe mental illness have more problems than other clients, primarily in the area of mental health. They spend more time alone and are more likely to engage in illegal activities. Interviewers assess their situation as more serious and that they need more help in all of ASI's areas of life than other clients.

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.
