The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

The purpose of this study was to describe and analyse the living situation of children who practiced Muay thai at two different Muay thai schools in Thailand. The metod I chose was participation studies with the compliment of open interviews. My main questions were to see if and how the children were affected physically and mentally by the training and possible matches. I also wanted to see if Muay thai practiced by children could be considered child labour, reasons why the children did Muay thai and what opportunities Muay thai gave the children in other parts of their lives.My conclusions were that the training gave the children an overall god physical status, and did not affect the children in any direct negative physical way. Mentally the main affect on the children in training were the stress of not being allowed to eat before matches.

In this essay I have summarized important factors for an effective, but also successful, way to raise and house heifers. This study can be used for other dairy farms to use as guidelines in their process to raise heifers. To let outside heifer growers house, feed and have the heifers pregnant before return, can save a lot of work. But also moneywise, when the care and individual programs makes them strong and increases the growth.The result is a faster breeding and an earlier time for their first calving.In Sweden the heifers tend to be older if you compare with Denmark or United States where the custom heifer raising is well known and growing. One reason can be the Swedish laws regarding outside grassing for all cows during the summer months.

The wind power increase of Gotland as well as other parts of Sweden during the last ten year period has meant that this renewable energy source has increased its share over other fossil sources. The year of 2011 became the first when the wind power produced more energy than an average nuclear reactor. Now that wind power is in an expansive phase, the land issue will be of great interest. Land with good wind resources will be of interest to wind energy developers. The problems that this essay is based on are; how can landowners altering the economic conditions at a wind power establishment? What opportunities and obstacles exist for landowners who choose to set up wind power on their land? The purpose of this essay is to highlight the economic conditions that exist for landowners for the establishment of wind farms, with regard to compensation for the leasing and return on invested capital.

The aim of this master?s study is to examine the function of the public library in the local community at present. I have searched for the answers to the following questions: Which position has the public library in the local cultural policy? What characterizes each library and which are the priorities? What is the local profile of the public library? What cooperation partners does the public library have and what do they mean to the library? Does the public library intensify the local community in any way? To answer this, I have made three qualitative case studies. Interviews and collection of documents were carried out in three different communities.

This master of science thesis intends to examine how the established innovation theoriesinteracts with the social and cultural phenomena arising from the reduction in communicationcosts as a result of the development of the internet.The aim is to present a knowledge inventory of attitudes to and experiences of an openapproach, with emphasis on collaborative innovation, in product and service developmentdriven companies in different fields. The studied theories and the empirical results forms thebasis for an analysis of how companies can benefit from the diversified knowledge that existsoutside their borders as well as an exploration of the potential for this kind of knowledgeexchange to act as a catalyst for innovation.The theoretical part of the study is based essentially on two tracks: (1) innovation theories witha focus onopen innovation and user innovation, and (2) a broad review of how theories ofdiversified knowledgeand collective intelligence has become possible to apply in an innovationcontext. The empirical part of the study is based on material obtained from semi-structuredinterviews with respondents from six companies.The results show that companies have implemented unstructured innovation initiatives withoutany formal links to the structured product development processes, which are part of thecompanies core activities. The main conclusions include the following insights: There is a needfor structured links between the unstructured initiatives and the core activities, which makes itpossible to take promising ideas to market. The companies also have to lose some control of theunstructured initiatives; consequently it is impossible to pinpoint what the outcome will be.

This essay presents an investigation of the ruins of an assembly of crofts in a rural area in the south of Sweden, outside the town Falk?ping. Using literary sources and intangible sources, and then combine them with the information found by investigation of the physical remains of the crofts, the essay attempts to capture the life and the living conditions of the crofters. The investigation is focusing on the period between the nighteenth century and the first decades of the twentieth century, and looks into the the living conditions according to, for example, the buildings, the orientation in the landscape, demografical changes, the transformation of the area over years and how the crofters were affected by powerty. The investigation shows that the crofters in many ways were in vulnerable and exposed positions, powerty summarized as a lack of freedom ? concerning economical, political and social dimensions.

The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand. The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted. The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages. The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent). Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated. Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same. However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time. If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..

This report shows the process of the development of a sensor module for the seed drills of Väderstad Verken AB. The module is supposed to replace existing solutions, provided that it is better from both a constructional- and an economical aspect. The purpose of the sensor is to continuously give the driver information about the level of height of the front- and drilling tools and the main purpose of the sensor is to allow the seeds to be placed at the desired depth. The sensors which have been taken into consideration have all been of an analogue type and have a protection class of minimum IP67.The methods applied have been taken from the book ?The Mechanical Design Process? by David G.

The Swedish potential of electricity production from roof mounted solar panels has been determined in three steps: accessing the existing roof top areas, simulating the amount of electricity solar panels can produce on these areas and finally analyzing how large the necessary economical change is to make the solar cells profitable.The total existing amount of roof top areas are 319 square kilometers and the area distribution follows the distribution of people. This leads to an installed power of 47,9 GW which are expected to produce 49,0 TWh electricity per year. If the quality of the electricity is prioritized the highest the power is reduced to 3,7 GW, generating 3,8 TWh yearly, but if the hosting capacity is calculated from Sweden?s total electricity need, the capacity is 42 TWh per year.Today, solar panels are not profitable in Sweden for houses, even though there is a subsidy of 35 % of the investment costs, discounted in 25 years. The profitability is calculated with a cost of capital of 5 %, a price on electricity of 1 SEK/kWh and an investment cost of 20 SEK/Wp.

Many studies have shown that unethical acting can affect the share price of the company negatively. However, this is not always the case. The aim of this thesis is therefore to examine what it is that can cause the share price to be affected negatively by unethical acting exposed in media. This qualitative study is primarily based on interviews with institutional investors, but also with economic journalists and investor relations managers. Our conclusion is that there are three main reasons why the share price can be affected by unethical acting, namely economic consequences, the management's behaviour and psychological factors.

The forgotten group: A study of support for relatives of incarcerated individuals. The daily lives of relatives of an incarcerated individual are affected and changed by the fact that their kin has become incarcerated. This made us want to research what kind of support these individuals are in need of and what kind of support the society is offering them today. Because of their kins behaviour, these individuals are also often exposed to feelings of shame and stigma. Therefore we have, with Goffmans theory of stigma in mind, looked into how this affects the relatives daily lives.

This Degree project is a study about the Mortgage Cap, introduced in October of 2010, and its impact on the demand for rented apartments. The mortgage cap was introduced to decrease the households? loan-to-value ratio and thereby increase their economical resistance during times of financial instability.The past ten years Swedish households have continuously increased their average loan-to-value ratio. In an attempt prevent this negative development Finansinspektionen introduced a mortgage cap stating that banks should no longer grant mortgages corresponding to more than 85 percent of the property?s market value.In order to answer the main question two methods were used both a survey and two interviews.

The purpose of this thesis is to examine a selection of ideological publishing houses in Sweden today. We want to examine where they are situated in the literary society, their terms and prerequisites. This is achieved through interviews with informants from each of the publishing houses, which we analyze with concepts from the culture sociologist Pierre Bourdieu. The publishing houses are also put in context through information from other actors in the literary field, together with previous research and other material about the Swedish book market. The main research problem in the thesis is to examine the relations between the selected publishing houses ? which profile themselves as ideological ? and the literary field where they exist.

ABSTRACT Tobacco Rattle Virus (TRV) is a soilborne plant virus. It is an important pathogen in potatoes where it causes spraing disease. This disease can lead to significant economical loss for the farmer, so it is imperative to get the proper diagnose before planting. TRV is spread naturally by free-living nematodes (Trichodorus and Paratrichodorus). Transference of TRV to a plant occurs when the virus-carrying nematodes feed on plant roots. The relationship between virus, nematodes and plants is complicated, and has to these days not been fully characterized. The diagnostic methods available today do not work sufficiently.
