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.

One problem in today?s indoor air quality lies within insufficient ventilation. Dynamic ventilation can be obtained by implementing a Demand-Controlled ventilation (DCV) system. DCV systems adjust the ventilation in a building by calculating the impact made by its? occupants.

The purpose with this research is to examine how the green marketing in retail trade can be developed in order to promote the eco-labeled products closer to the consumer.The method for the survey includes interviews with managers of a few retailers and their customers in the industrial sector. The purpose with the interviews was to produce the retailer and the customer?s perspective of products with eco-label on.The research is limited to the region of Västra Götaland.The results from this research indicate that there is a lack of communication between the retailer and the consumer. The consumers don?t think that the product is available.

Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.

Syftet med föreliggande uppsats var undersöka sambanden mellan motivationsklimat, målinriktning och självkänsla inom CrossFit jämfört med konditionsbaserad gruppträning. Vidare undersöktes om Modellen för sambandet mellan motivationsklimat, individuella skillnader, och känsla och motivation kunde appliceras inom CrossFit. I studien deltog sammanlagt 95 deltagare, både CrossFitutövare (N=45) och deltagare inom konditionsbaserad gruppträning (N=50) från sydvästra Sverige. I studien användes Perceived Motivational Climate in Sports Questionnaire-2 (PMCSQ-2), Achievement Goals Questionnaire for Sports (AGQ-S) samt Physical Self Perception Profile-R (PSPP-R). Resultatet visade en signifikant skillnad i uppgiftsorienterat klimat och självkänsla mellan CrossFitutövare och deltagare i konditionsbaserad gruppträning.

The purpose of this essay is to illustrate the ideas that have influenced parents' choice of a Christian private school and how parents justify their choices. The essay also aims to examine the expectations that parents have in the schools, as well as the pros and cons as they consider private school compared to other schools.My study is based on qualitative data collected through interviews with parents who have chosen to place one or more of their children in a specific Christian private school. Using a qualitative approach has made it possible for me to get a deeper understanding of this investigation. I have also used the previous research on this field and theoretical starting points to explain and connect to my inquiry as Maslow's hierarchy of needs and the school Weber document types and identity in a multicultural society.The study shows that parents seek to or from the public school due to various reasons. To seek out a Christian private school depends on different reasons.

High housing- and construction costs is a fact in Sweden today. Prices on building materials more rapidly than producer price index for industrial goods. Prices tend to rise during market boom but does not adapt during diminishing demand. The effects of fading demand can rather be deduced through discounts and quotations. During 1992-1998 when the Swedish construction sector found it self in severe crisis the prices of construction materials kept rising more rapidly than PPI for industrial merchandise.

The world has become a globalized place in constant development and much of which is now taken for granted did not even exist 30-40 years ago, such as smartphones or Internet in common households. As new tourist destinations is continuously being created, it becomes increasingly important with effective place marketing to compete in the global market. Developing a good and interesting profile is thus a way for places to become more attractive for tourists. The main theory in the paper is "post-industrialization and the entrepreneurial city" which describes how cities in the global north have moved away from industry towards becoming post-industrial cities ? very often with a strong focus on tourism.

Problem areaAlfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an increased demand of heat exchanger in the future. This increased demand is not something that existing lines will manage. To build new lines cost a lot of money and take time so it is essential that new lines are correct from the start and not need to be rebuilt or a lot of time spent to trim it.GoalThe goal is to achieve 100% theoretical utilization of the press (the press shall press the amount of plates it is designed for).

The Internet protocol of today has been used for over 20 years. A new version of the protocol has been developed to replace the old one. This is a direct result due to the explosive growth of the usage of the Internet. This follows by new demands which needs new solutions. This report brings up the old protocol IPv4, the new protocol IPv6 and shows what kind of changes that has been developed to meet the users demand.The report brings up two important aspects; internet security and mobility.

Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.

Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.

The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas. The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.

STRIX är Banverkets mest moderna mätvagn. Med denna utförs bland annat mätningar av rälsprofilen med ett optiskt system som är monterat under vagnen. I detta examensarbete jämförs mätningar från STRIX och mätningar från det handhållna systemet MiniProf. Målet med jämförelsen är att visa om nya metoder som har utvecklats under examensarbetet leder till förbättringar av mätningar utförda med STRIX. En tänkbar förbättring av de mätningar som utförs med STRIX är att byta den referenspunkt som används vid matchning mot en referensprofil.

In the master thesis the focus of the study has been on the special library of the Goethe-institute in Stockholm. A survey was made among the visitors coming to the library, to find out how they used the library and how they would judge the quality of service. To find out how the needs and the opinions of the users were meet by the library I also made an interview with the staff one librarian and the chief librarian. In the analysis I used the theory about service quality of Christian Grönroos as a framework. The theory distinguishes the service quality into technical resp.
