The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

Social enterprises are increasingly gaining ground as an organisational form in Sweden, however the institutional structures for financing these types of organisations are yet to be established. With its usual origin within the civic society, social enterprises prioritise a higher goal than to maximise economic profit, which often causes these organisations to be dependent upon resources from external constituents within its institutional environment. The aim of this study was to examine how a social enterprise, which derives from the civic society, acts to mobilise resources from constituents in its institutional environment. This was executed through a case study of Jordbro Världsorkester (JVO) - a typical organisation in the civic society which takes the form of a social enterprise - by identifying how assets were used to gain resources in strategic responses to institutional processes and examining how institutional processes affects how JVO acts. Throughout the study, qualitative interviews were conducted with JVO and constituents in its institutional environment and a theoretical framework was developed which explains how capital is used to gain more capital in an emergent strategy of strategic responses as the organisation gets in contact with institutional processes from its institutional environment.

It is very important to get the work environment into the daily work, not least in the construction industry. The purpose of this report is to identify how the process with work environment works. It will identify and clarify the problems that exist.In my work, I have studied how the NCC Östergötland is working with these issues. The focus of the report is on my interview and survey questions. My conclusion and discussion is therefore based on the answers I collected and compared.

Dancewalks är ett platsspecifikt danskonstverk skapat och uppfört i olika semioffentliga rum. Den här kvalitativa studien undersöker resultatet och effekterna av en Dancewalks i Malmö där 30 arkitekter och stadsplanerare deltog. Dancewalks är i sig själv ett performance vilket påverkar studien och därför också undersökningsprocessen. Det teoretiska ramverket utgår från Non representative theory och teorier om hur människor interagerar i rum. Tillvägagångssättet för studien är en triangulering av observation, fokusgrupp och semistrukturerade intervjuer.

Employers are becoming more and more aware of that the internal communication between employees is the reason why organizations are being held alive and also what impact the office environment has on employees work performances and their communication. The aim of our study was to gain an understanding of what significance an office's spatial design has for the communication between employees and managers in the workplace. We have through qualitative interviews with managers and employees from different business cases gotten a perception of their ways of communicating with each other. The results showed that employees and leaders thought that they shared the same picture of what their communication was like in reality, how they thought their ways of marking their territory in the office was understood and respected and what their opinions and expectations of how the communication between them and their leaders should be like. These results were then analyzed in consideration with relevant theory and previous research in the disciplines of office environment and communication studies.The main conclusions that have been drawn from the analysis are that the work environment's design can be both positive and negative at the same time and that what should be focused on is the leaders' communication. The leaders and their employees have to communicate more about their communication between them so thart misunderstandings can be avoided in the office environment - and therefore become more effective..

It's not a secret that most companies strive to get such a high economic return as possible. To successfully engage in a profitable enterprise, there are many elements that come into play. An important element is the motivation of the employees and their work performance. Work motivation is a key factor for the employees to improve their performance and therefore determinant for the successes of the company.This work is a case study in the production at Fresenius Kabi, Uppsala. The work is based on an employee survey that they fill out once a year and the aim is to develop a deeper understanding for these questions and how the employees see on leadership, communication and goal-setting as motivators and how these factors works in the company today.To get this deeper understanding I have used a qualitative approach.

This study deals with the complex phenomenon of occupational health. There is knowledge of how a good work environment should look like, but despite this, many employees experiences ill health in the workplace mainly in the form of neck and back pain. This study is a case study conducted in a high-risk workplace. The overall purpose was to describe and analyze the health situation of a specific company with neck and back problems. Mainly, eight interviews had been used as the data collection method, but additional observations had also been implemented.

In this thesis, input data for energy performance calculations on commercialpremises have been studied. In energy performance calculations, where internal heat gain parameters are unknown, template values that, in a reasonable way represent the activity in the room, are necessary. These values can be used as input data for whole-year calculations, or for calculations on shorter periods of time.The purpose of the Sveby project is to create standardized work practice in energy issues for the construction industry. The work in this thesis is conducted to correlate with the purpose of the Sveby project, with aims of contributing with information and guidelines for the continuing work with commercial premises.In this report, suggestions for template values for internal gains parameters, based on research and calculations in the field are presented. Suggestions on how these can be implemented in a user-friendly way for two energy performance calculation software are also given, VIP Energy and IDA ICE.

It is not uncommon for math difficulties and reading difficulties to occur simultaneously. Despite this, math and reading difficulties are thought to have different cognitive profiles where math difficulties are linked to number sense; an innate ability to understand, approximate and manipulate both quantities and numerical information, whereas reading difficulties are linked to phonological ability; an innate ability to understand, create representations of and manipulate phonological information. A possible link between the difficulties is that phonological abilities also could affect mathematical ability. Support for this comes from studies where comorbid math and reading difficulties are associated with more severe difficulties in arithmetic ability compared to those with isolated math difficulties. The purpose of this study is to examine whether isolated math difficulties, isolated reading difficulties and comorbid math and reading difficulties can be linked to deficits in number sense, phonological ability or both of these, and whether comorbid math and reading difficulties differ in performance in mathematical tasks compared to isolated math difficulties for children in second grade.

Manystudies have investigated the effects on different carbohydrate intakes on training performance. Thescientific researchers have met a consensus in the fact that a higher intake of carbohydratescompared to a lower carbohydrate intake improves athletic performance. Lately, the increasedinterest in low carbohydrate diets has despite these recommendations gained followers globally.ObjectiveTo determine if a higher carbohydrate intake results in a better endurance performance, comparedto a lower carbohydrate intake, for adult males and females, measured as time to exhaustion, totaldistance covered and power output/cadence. To be able to give nutrition recommendations toendurance athletes based on the current scientific evidence and identify if there is need for furtherresearch in this area.Search strategyThe databases used for the literature search were PubMed and Scopus.

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.

Background: Today, the trademark is the heart of the company and the management of brandimage and identity require certain attention and care. In an increasingly tough business climatewhere the brand today has a central and important role, it is understandable that the companieswant to take maximum advantage of it. In the company the brand is a great resource with analready known identity and established values that can help new products to enter the market. Toextend the brand is a popular growth strategy but it is important to do it properly in order not tofail. J Lindeberg and Peak Performance are two Swedish fashion companies which both havemade brand extensions.

The heterosis effect and breed group effect of crossbreds between Swedish Holstein (SH) and Swedish Red (SRB) was estimated in this study. Observations on cows born between 1990 and 2012 were used to estimate the heterosis effect and breed group effect for several traits included in the Nordic breeding goals: production, fertility, udder health, calving performance, survival and other diseases. Breeding within the Holstein dairy breed has earlier been focused on increased milk production and conformation. This, combined with an intensive use of individual animals, has resulted in a radical increase of milk yield in the Holstein dairy cow population all over the world. However, this breeding strategy has resulted in increased inbreeding and several functional traits have impaired.
