Försäkringsbolags kostnader för reparation av fuktskadade badrum
The purpose of this report is to compile and examine the cost of renovation of moisture-damaged bathrooms, to derive a target price. The target price can then be used by insurance companies to estimate the ultimate cost of future bathroom renovations. The method is based on the compilation and comparison of the cost of repairs of previous water damage in bathrooms. The calculations compiled based on repair estimates for different insurance losses from one of the leading insurance companies in Sweden. The result shows the average price per square meter of floor area for different sizes of bathrooms. The average price is the basis for the estimate of future renovation costs of bathrooms. The results further show that the bathroom finishes, area and the distance between the entrepreneur and the location of the renovation have great impact on the final repairing cost.
Word of Nextopia - en djupare förståelse av Nextopia och hur det påverkar Word of mouth
The purpose of this study is to further develop the understanding of Nextopia, the belief that the next product will always be better, and the effects it has on Word of mouth, both oral (WOM) and electronic (eWOM), and investigate possible causes of this effect. This has been made through an experimental study of responses to two mineral water ads, with a manipulated time frame. First, this thesis supports the fact that there is a general Nextopia-effect on customers being exposed to a future product, which makes them evaluating the product higher in terms of feelings, attitude and intention. Further this study shows that there is also a Nextopia-effect on WOM and eWOM, by customers being more likely to recommend a future product rather than a current one. This propensity to recommend the product also has a relationship with responsibility, which correlates much stronger with WOM than eWOM.
Profylaktiska åtgärder för kaniner
Rabbits, Oryctolagos cuniculus, rapidly increases as pets. During the right circumstances, rabbits are friendly, social and playful. A rabbit who shows an abnormal behavior should always be examined by a veterinary, though there is almost always a medical problem.
This essay is a result of a literature studie with the aim to find the prophylactic measures that may give pet rabbits a more healthy life. Rabbits have got a lot of common health problems, including dental, skin and gastrointestinal problems.
Biogas på Wapnö : Analys av framtida energisystem
Considering that the price and demand for energy gradually has risen over the past decade and a wider discussion about the human impact on the environment has become increasingly more important and given a clearer role in modern society. This has contributed to increased incentives to reduce the use of fossil fuels and increase the use of renewable energy.The agriculture currently accounts for 20 % of Sweden's total greenhouse gas emissions. A way for an agricultural company like Wapnö AB to reduce their emissions could be to utilize existing renewable energy sources within their own premises.The report's aim is to create an energy audit of Wapnö?s existing energy system and how it changes with a future biogas plant in operation. The energy audit is used to illustrate how the company?s climate footprint could change.
Lönsamhetsanalys av tekniker för utökad elproduktion i kraftvärme : Med hänsyn till elprisets variationer
This thesis aims to examine the viability of various techniques for increased electricity generation in CHP plants and the effect of electricity price fluctuations on the profitability.The techniques examined are fuel dryer, pellet production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated.What affects the price of electricity is a combination of economic and technological development, energy prices, economic structure, population changes and weather. Different scenarios for the electricity price were therefore examined. In the base case, the electricity price was given by the Nord Pool electricity price statistics of area three in 2011. Thereafter, WiMo was used to design the electricity scenarios for 2030, which was then applied to the data to obtain the viability of various scenarios. The techniques examined were found to give greater profits to the CHP plant by increasing and optimizing the production of electricity.
Ekologisk gestaltning : en utvärdering av hur landskapsarkitektur påverkas av ett ekologiskt förhållningssätt
This paper examines and compares several different sites in Sweden in addition to one in Mexico regarding whether the ecological requirements theses sites have had during planning and construction has affected the design in any way. Is it possible that, for different reasons, one thinks ?like nature? when one thinks of ecology and, if true, how does this reflect on the spatial and structural design? This paper tries to identify if some sort of general design expression is used in projects with requirements on ecological sustainability. In total, five projects have been compared in different areas such as choice of materials and their composition.
These projects have an ecologically sustainable processing of water in common, although most also have ecological consideration in other areas as well.
Energi - och ekonomipotential för solceller i Hållbara Järva
One of the city of Stockholm?s main objectives is to have a society completely free from fossil fuels. To achieve this, several investments regarding improvements in energy efficiency and renewable energy are currently being planned or implemented. One of these investments is a project called Hallbara Jarva which is located in the suburbs of Stockholm. The purpose of this thesis is to examine the prospects of an investment in photovoltaic cells from an energy-saving and economical point of view. The analysis is limited to three buildings within Hallbara Jarva and is intended for the property owner. Solar energy is a type of renewable energy source and is commonly divided into solar heating and solar power.
Kan gullstånds hålla stånd?- återinventering av Senecio paludosus i Kristianstad Vattenrike 2012
Botanist Kjell-Arne Olsson inventoried the plant fen ragwort Senecio paludosus 1983 in Scania andfound a big number of locations within Biosphere Reserve Kristianstad Vattenrike. In 2012, a reinventoryof the 1983 survey was carried out to study whether there has been any change in the fenragwort population in Kristianstad Vattenrike since the last inventory. The results show that therehas been no overall change in the number of fen ragwort in Kristianstad Vattenrike, on certainpremises they have increased in number while in others they have fallen. However, the inventoryshows that almost half of the locations with fen ragwort have disappeared during the same period.The main reason for this is that fen ragwort did not manage to competitive with other vegetation,taking in consideration this has been smaller premises with young plants. In addition to competitionother factors such as prolonged high water, grazing and caterpillars from Tyria jacobaeaecontributed to the decrease.
Ha?llbarhetsredovisning i bostadsfo?retag : En rekommendation
This project was conducted on behalf of the organization SABO (Swedish Association of Public Housing Companies). The aim of this project was to investigate which relevant environmental aspects and indicators there are for housing companies to present in their sustainability report. The project consists of three main goals: to decide if there is a need for common guidelines when conducting a sustainability report, determine appropriate environmental indicators and to create a simple model of how the companies can present them. This was done by a literature study, analysis of 13 sustainability reports and interviews with seven housing companies. The result of the project suggests that there is a need for common guidelines to, among other things, make it easier to make a comparison with other companies.
Elevers föreställningar om vattnets kretslopp och växtens liv : Har eleverna tillräcklig kunskap inom dessa områden för att diskutera hur miljöförstörning påverkar vatten och växter?
The purpose of this investigation is mainly to study if pupils have enough knowledge concerning the water cycle and the life of the plants?, and what kinds of household word they have, to discuss pollution within these areas. I also studied how the pupils? knowledge are holding up against what the course-plans says, since it have come to light by other investigations that knowledge are insufficient within the nature-oriented (No) subject in school.The survey has carried out on 28 pupils in a 5th grade, with help of a questionnaire survey. Their teacher has been interviewed and I have studied their local course-plans and also the pupils? schoolbooks in No.The result of the questionnaire survey indicates that the pupils had insufficient knowledge within the areas of plants? life and pollution, something their teacher had a presentiment about.The conclusion is that they need to go out more often in the nature and see how the plants and the environment are affected by different factors.
VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor
Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.
EAS-tagg med fuktsensor : Design och utvärdering av EAS-alarmteknologi för fuktdetektering
Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.

The town I have picked for this study is Kalmar situated on the east coast of Sweden. This study is a micro historic case study. The specific case is a strike at the city?s water and gas plants for higher salary.
GRÖN FLAGG : Miljöarbete i förskolan
The aim with my work is to get a deeper knowledge about the preschool's views of environmental work. I also want to examine how the preschool teachers along with the children work with the project Green Flag in the preschool. I have used structured interview with two teachers in a preschool that works with Green Flag. Green Flag is an environment certification and is an evidence on that one works daily with a document aimed environmental work along with the children. I have found out that each year they work with different themes within Green Flag.
Ekonomi i Passivhus : En studie av två verkliga byggnader
The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.
