Life Cycle Cost : Studie om LCC som verktyg att utva?rdera geoenergianla?ggningar

Life Cycle Cost, often abbreviated as LCC, is a common tool for comparing the total cost of different alternatives, such as heating and cooling methods. Common heating and cooling methods in Sweden are geothermal energy, district heating and district cooling. This report aims to evaluate how different heating and cooling methods differ from each other while being applied on three different types of buildings, using selected LCC-models. Information about the selected LCC-models wasretrieved from each separate model and its website. Reports and agencies were used as sources for information about the heating and cooling methods.

Projektering av ett småhus samt ekonomisk jämförelse av värmesystem

Design of a house requires knowledge of both technology and economics. Heating and ventilation shall be designed, costs are calculated and estimated and requirements must be fulfilled. Which heating system is to be elected is also a difficult choice, especially with rising energy prices as a factor.The choice of energy system is not always given, because it depends on several factors. Below is a comparison between district heating, geothermal heat pump and electric boiler from an economic standpoint. In a previous report appears district heating and geothermal heat pump as the best options.

Kyrka, teologi och samhälle En studie av Stanley Hauerwas och Max L. Stackhouse

The discussion concerning what role the church and theology should have in a modern, western society is a question that is ongoing in Sweden as well as in other countries. The present; American theologians Stanley Hauerwas and Max L. Stackhouse have different ideas concerning the identity of the church and theology as well as their relation to the society they are in. This essay surveys their views on the church and the theology and how they should relate to the society. Hauerwas focuses his theology on the church, and the first part of the essay deals with his view on what makes a church, how it differs from the rest of the world and what the church?s calling is.

Ants and termites in small-scale plantain farms in Uganda : a comparison between agroforestry and non-agroforestry farms

This study was conducted in Kkingo district, west of Masaka, Uganda. It compared soil macrofauna abundance in non-agroforestry farms with that of agroforestry farms. The agroforestry farms had participated in the Vi Agroforestry´s program between 1995 and 2006, and continued on their own after 2006, when Vi Agroforestry left the area. The soil macrofauna is important for soil structure and processes that are contributing to soil organ-ic matter decomposition and nutrient mineralization. They are also predators of potential pests.

Sälja eller låna ut, är det skillnad? - En experimentell komparativ studie av återvinningseffektivitet i bibliografiska databaser.

The aim of this thesis is to answer whether a group of databases dedicated to selling books or a group of databases dedicated to lending books is more efficient. The measurements used to determine the efficiency of the two kinds of databases are Cumulated Gain and precision in modified versions. The inquiry has been conducted thus that the same 18 queries have been put forth to six databases and these results have consequently been judged according to relevance on a 4-graded scale by five respondents. The rankinglevels have then been merged to one average value per respondent and ranking. These values have then been used to determine CG/iCG/nCG and P@n per query, rank 1-10, per database and per group (the groups being STORE (BUTIK) and LIBRARY (BIBLIOTEK).

Intresset för fysisk aktivitet - en jämförelse mellan elever i årskurs fem på två skolor med olika inriktningar. The interest of physical exercise - a comparison between students in 5th grade at two schools with different concentrations

Det främsta syftet med denna uppsats var att prova en hypotes och se om elever i årskurs fem på en skola med hälsoprofil påverkas till en mer fysisk aktiv fritid än de elever som går på en skola utan hälsoinriktning. Ett undersyfte var även att se om det finns någon skillnad på idrottsintresset hos flickorna och pojkarna. Huvudfrågan är ?Hur ser elevers motionsvanor ut på fritiden på en hälsoinriktad skola jämfört med skola utan inriktning mot hälsa?? För att få svar på frågeställningen gjordes en enkätundersökning på 70 elever i årskurs fem på två olika skolor. Därefter gjordes intervjuer på sju slumpvist utvalda elever på hälsoskolan för att lite tydligare få fram vad som motiverar dem till fysisk aktivitet. Genom litteraturundersökning tog jag reda på tidigare forskningsresultat och även vad skollagen har för krav och mål vad gäller ämnet idrott och hälsa.

Comparison between different freezing and thawing methods for human spermatozoa

Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.

Med Barnkonventionen i bagaget: En komparativ studie av irländska och svenska barnbibliotekariers synsätt.

The aim of this Masters thesis is to examine how five childrens librarians in Ireland and five in Sweden interpret and implement the United Nations Convention on the Rights of the Child in public libraries. This study is hermeneutic. Using a qualitative method consisting of ten interviews with childrens librarians and structural factors such as; library policies and laws; together with an insight into Irelands political, social and economical history and the historical development of childrens public libraries in Sweden and Ireland, has enabled us to create an understanding for the interviewees statements. Anthony Giddens structuration theory has been used for the analysis, helping us to determine how the duality between the structure, the actors and their action effect the interpretation and implementation of the Convention in librarian work. The result of the analysis clearly shows that in comparison to Irish librarians, the Swedish interviewees are more aware and have a better understanding of the Convention and how to put it into practice.

Kvinnors roller i vikingatiden : utifrån exemplet Birka och skriftliga källor

This essay discusses the issue of the role of women and also whether they could obtain a strong social position during the Viking Age. Moreover, it does discuss the question of how frequent women were present in Viking Age scriptures, art and archaeological artefacts in comparison to our view of women and her position in the modern society. The archaeological material used is in majority that found in Birka, such as burial and habitational findings. These objects, as well as other comparable and similar findings from other places, when put together with written sources, show that women had different roles in the society. She was able to have a strong social role during the Viking Age not only becauseof the status her family had but also because of her own merit depending of her skills and ability.The archaeological findings found in female graves and other findings in the area, suggest a specializing within both textile production and trade for the women.

Observiaire och film som analysmetod för cykeltrafik : En fallstudie på Götgatan i Stockholm där omställningen till supercykelbana utreds

The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

Effektivisering av urvalsprocesser vid analysering av björnspillning : Ett förslag till den svenska förvaltningen av brunbjörn Ursus arctos

The aim with this report is to formulate a strategic method to optimize selection processes of DNA-samples from a faeces inventory to identify as many individuals in as few analyzes as possible, and by that keep down the costs of brown bear management. Brown bear management in Sweden founds today on results from faeces inventory and is substantially led by the county administration boards. Data from the years of 2004 and 2009´s inventories in Västerbotten was used to test and evaluate different methods in selection processes of which faeces that should be sampled. Comparison were made between making selection by chance, by spatial distribution and by calculating variations in logistic regressions coefficient b, in other words bear density and probability in finding same individual in several faeces. We can show making selection by chance is the most uncertain method.

Från läsesällskap till stadsbibliotek: Skövdes bibliotekshistoria 1830-1940

The purpose of this Master?s thesis is to describe the development of the most important libraries in Skövde, starting from 1830. We conclude our examination about 1940, when the municipal library has been active for almost ten years, and the libraries started by the temperance and working-class movements have been deposited at the municipal library. In order to explain this process we describe the development of the Swedish public library and its predecessors, such as reading societies and the popular national movements? libraries, as a background and comparison to the early libraries in Skövde.

Stor blandning - lika behandling. En bra metod för jämställdhetsarbete : en utvärderingsstudie av Svenska innebandyförbundets likabehandlingsprojekt

The aim of this study is to evaluate whether the working model, presented by The Swedish Floorball Federation, has been a good method to work with gender equality within Swedish floorball associations. The purpose of the The Swedish Floorball Federation?sproject was for its associations to develop a plan of action for how to act to be an equal treatment association pursuing an equal treatment sport. 13 associations answered the questionnaire study. The result show that the great majority clearly found a need of change to become more equally treating and most of those associations have somewhat of an idea how to realize those changes.

SL.se från användarens perspektiv : En granskning av Storstockholms Lokaltrafiks hemsida

This study is a thorough comparison between what people think about the website www.sl.se, which is a Swedish web-based travel planner for Stockholm metropolitan public transport (such as subways, busses and suburban trains), and how these views compares to the design of the actual website itself. The travel planner offers a wide range of functions and services for their targeted audience to find the fastest route between their current location and their destination. These functions are for example real time information on hold ups and malfunctions on different travel routes, and an interactive map of specific destinations so that the user can get a clear view of the area and nearby traffic stops. But how much does the average user care for these functions, and how often are they used on an average visit? What are the users? motivations when they visit the site? Earlier research suggested that there are services and functions on this website that are useful and well crafted, but that some people may not be aware of.
