Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus
The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.
Distriktssköterskans möte med föräldrar som ställer sig tveksamma till MPR-vaccination
Vaccination as a part of the preventative public health project has for many years been one of the important tasks of the children's health care. The vaccination program has been adjusted to current research and the health situation in the country. Having their children vaccinated is not something obvious for all parents, though. Especially the vaccination against measles, whooping cough and German measles have been questioned. The purpose of this literature study was to investigate the reasons for the resistance to vaccinate and to illuminate the security creating advice of the nurse at the public health centre.

This study seeks to evaluate wastewater as an energy resource and to examine treatment plants potential to become sustainable energy producers. The study is based upon the internal processes of Himmerfja?rdsverket.
Resurseffektiv livsmedelsproduktion : Tillämpning av industriell symbios för ökad resurseffektivitet inom den svenska tomatodlingsbranschen
Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.
Peritonealdialysens inverkan på dagligt liv bland personer med kronisk njursvikt.
Antalet personer med kronisk njursvikt ökar i Sverige, orsakat av att diabetesnefropati ökar, som en följd av att allt fler får diabetes mellitus typ 2. Peritonealdialys är en behandling för personer med kronisk njursvikt och kan skötas i hemmet. Syftet med studien är att beskriva hur peritonealdialys inverkar på dagligt liv bland personer med kronisk njursvikt. Studien genomfördes som en allmän litteraturstudie och vetenskapliga artiklar har sökts via elektroniska databaser och manuella sökningar. Femton artiklar granskades och analyserades med hjälp av innehållsanalys.
En studie av den svenska människohandelslagstiftningens effektivitet
This paper aims to give a comprehensive view in which extent Swedish legislation concerning trafficking in human beings (Brottsbalken 4 kap. 1a §) is efficient. Qualitative interviews have been carried out with professionals within the judicial system in order to comprehend various aspects of efficiency relating to legislative validation of trafficking regarded human beings. Consent, coercion and control brings up miscellaneous issues. Personal observations by authorized people within the area was therefore viewed and found to be highly essential.
Anonymitetens implementeringsproblem - En studie om Kortedalas försök av avidentifierade jobbansökningar
Anonymous job applications as a method to further diversity on the labour market is widely discussed. The method aims to promote an equal selection procedure, where the employer can only judge on merits and experience. We are with this study on the other hand interested in seeing how this specific method of employment has been implemented. We have chosen to perform a small qualitative case study, of a limited attempt of this method in the government administration of Kortedala, a district in Gothenburg.Our intrests are to see whether we can, while studying a specific implementation procedure, show that any implementation problems have occurred. Furthermore explaining it by applying our implementation theory, that consists of Lennart Lundquists three criterias for explaining implementation problems experienced from the appliers' standpoint.
Luftfuktighetens påverkan på konstruktion och klimat i en berghangar
Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.
Kulturpolitikers syn på folkbiblioteket ? en studie i Västerbottens inland.
The main purpose of this Master thesis is to illuminate the understanding of local politicians regarding the public libraries and the librarians. We argue that the local politicians´ opinions regarding public libraries and librarians influence the way they act and react in their roles as politicians.In order to achieve the aim of this thesis we focused on following questions:What are the opinions of the politicians:- regarding themselves in relation to the public library?- concerning public libraries in general and its functions especially in the municipalities of their own?- concerning the librarians and their work in a public function?What are the conclusions to be drawn regarding the politicians´ interest and commitment to public libraries in the politic daily-life of the municipalities? Our empiric material consists of qualitative interviews with six politicians elected in two municipalities in the interior of Västerbotten, a northern sparsely populated district. In order to distinguish the various opinions that emerge from the material, we apply a phenomenographic approach. The analysis result we present in three conceivable categories in order to express the different opinions.In general our study points at a positive and favourable attitude to the public library, and all the respondents assume that the municipality ought to offer this service.

Det skånska svärdet från 800 till 1300 e.Kr. : Fallstudie av 8 svärd
This essay discusses the development of swords in the southern region of Sweden, Skåne. It attempts to locate the areas in Europe where the swords were first made and, in doing so, trace the communication routes by which people traveled. The essay deals with aperiod of a few hundred years, from the late eighth century to sometime around 1300. In that sense, it is therefore also a time study tracing the cultural changes and developments in Skåne during the era of Christianization. Does the development of swords follow the overall changes in society, from an isolated pagan district to a Catholic European community, or not? In answering this question, eight swords were selected and put under closer observation.
Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion
Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.
