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.

Volvo Group Truck Operations i Umeå arbetar med arbetsmiljö och säkerhet på arbetsplatsen genom en så kallad säkerhetspyramid. Säkerhetspyramiden baseras bland annat på medarbetarnas rapportering av osäkert agerande och osäkert förhållande. Syftet med pyramiden är att identifiera risker och förhindra arbetsplatsolyckor. Baserat på rapporteringsstatistik och teoretiska antagandena i säkerhetspyramiden finns en anledning att tro att det förekommer en underrapportering. Syftet med studien var att undersöka om det fanns en underrapportering av osäkert agerande och osäkert förhållande bland kollektivanställda på presshallen och kaross.

Syfte och frågeställningarMitt syfte var att finna eventuella skillnader i träningseffekt mellan ren koncentrisk och excentrisk styrketräning. Jag har därmed utgått ifrån följande frågeställningar:? Skiljer sig tung excentrisk och koncentrisk styrketräning åt i effekterna på styrkeprestationer i form av hopptest och styrketest?? Skiljer sig effekterna av träningen åt mellan män och kvinnor?MetodUtifrån syftet och frågeställningarna gjorde jag en studie med ett antal testpersoner där de fick genomgå ett antal tester innan en träningsperiod och samma tester efter träningsperioden, som pågick i tio veckor. Hälften var kvinnor och hälften var män. Den ena gruppen tränade bara koncentriskt (KON) och den andra gruppen bara excentriskt (ECC).Testerna som utfördes före och efter träningsperioden var: isometrisk styrketest, omkretsmätning av lårmuskulaturen, squat jump, counter movment jump, drop jump och benpress i släde.ResultatDet fanns en tendens att den excentriska träningsgruppen hade en ökning av sin omkrets efter träningen, medan den koncentriska inte visade en sådan tendens.

Patients who undergo surgery receive general anaesthesia or any form of conduction anaesthesia during the operation. For most people it is strange, unexpected and for many something completely new to be a patient and undergo surgery. Awake conduction anaesthetic patients? experiences from the intraoperative period were little studied. The purpose of this study was to examine awake conduction anaesthesia patients? experiences.

This paper concerns the freedom of speech in our democracy and the principles underlying the restrictions. The study is aimed at using a descriptive theory to provide a useful basis for analyzing a justification of the role behind freedom of speech and its limitations. The analysis is made on the basis of the Swedish parliament debate in the form of motions and the non-governmental organization Swedish Helsinki Committee's report. The study has a focus on the law of hate speech and will be done with an idea centred analysis. On the basis of democratic theory, the central role of freedom of speech was clarified on the basis of a clear need for a reliable communication.

The first aim of this thesis is to descriptively identify and chart the activities of the strategic intelligence and environmental scanning that take place at the regional collaboration network Regionförbundet Örebro. This identification is essential in reaching the comprehensive and primary aim of the thesis: to discuss, through normative discourse, what the options of improvement are and in which ways systematic operations can be integrating parts in the organization. In order to offer guidance of development from the perspectives of environmental scanning, the question at issue has emanated from activities concerning the present methods of working at Regionförbundet Örebro.During the creation of this thesis, several interviews have been made with people who are regarded to be key roles within the regional collaboration network. An analysis has been made, based on governing documents and answers from the interviews, where possible improvements of the business have been identified. The inferences become parts of a greater potential of amelioration since they are presented as active solutions and proposals that can be directly adaptable to the organization.Our proposals of improvements/ameliorations are constituted by a number of concrete/explicit points such as: a wider public information supply and an introduction of several annual routines and methods..

The aim of the study was to investigate how a community motivates and ensures the implementation of its values and how this document affected personnel of meaning, vision and daily operations. The study was based on semi-structured interviews, in which nine respondents were interviewed in a city in southern Sweden. Interviews dealt with three different themes, all concerned organization or set of values. The analysis was based partly on how organizations and institutions build up and maintain their legitimacy. The analysis was also explained by the new institutional theory and its concepts isomorphism.

This thesis is carried out at Portsystem 2000 AB who manufactures and markets industrial doors and docking systems. The background to this thesis is that the company?s management considers that their follow-up process of cost accounts is not fully functioning.The aim with this report is to investigate and describe the present procedure of the follow-up process concerning the time of operations and come up with suggestions for improvements. This thesis is performed within the range of the following areas: Information systems, quality, processes and cost calculation. The main method we used were semi structured interviews with a fairly opened framework.

The aim of this study is to investigate into the use of discussions in the classroom to help the pupils develop a deeper understanding of mathematical concepts and operations. The empirical data contain interviews with two teachers and observations from their lessons. The purpose of the interviews was to find out what importance the teachers ascribed to the ability of their pupils to talk about mathematics, and how they organised their classes to encourage mathematical discussions. With the observations, I was able to see the interaction in the classroom and hear discussions between the teacher and the pupils, as well as between the pupils themselves.The interviewed teachers proved to share my own belief in the results of researchers like Malmer (1999) and Löwing (2006) about the importance of verbal discussion, argumentation and reflection during mathematics classes. But convictions derived from the research of others are one thing, the practical application of the wisdom in the classroom another.

For organizations that handle sensitive information, IT governance and information security are necessities in order to maintain credibility and to conduct its business efficiently. There are several known processes to increase security governance ? which is a fusion of information security and IT governance.This master thesis examines if organizations use recognized processes and if it in that case would lead to higher security. The study is qualitative and conducted in the financial sector and based on Best Practice frameworks of the security governance in Swedish banks. Data collection was done through interviews and surveys that were triangulated to get a gathered picture of the quality of the security governance activities.

This thesis investigates lacks in today?s use of the ERP-system Mapaz Affärssystem inthe production planning at Solna Pressgjuteri, and possible improvements. Today thedates calculated by the program to plan the orders are inaccurate and the ordersequence is not optimal, and therefore continuous manual corrections are needed.The approach was to study the program Mapaz to understand how it works, andidentify available parameters for input and output in the different tools offered in theprogram. By studying old lists of planned orders and relevant parameters in Mapaz forindividual orders, production groups, products and operations, the connectionbetween input and output parameters could be understood.Participating in planning meetings and discussions with the company behind theERP-system identified the current usage, desideratum and possibilities with theavailable tools. These were then matched to describe the reasons to the insufficientplanning and form possible actions for improvement.The work has showed poor understanding for the ERP-system and its functions, assome tools intended to assist the planning were not used, and some even usedincorrectly.

Begreppen upprorsbekämpning eller counterinsurgency (COIN) ochstabiliseringsoperationer utgör ett debatterat ämne i den dagsaktuella militärteorin. Bådabegreppen förefaller användas för en och samma typ av operation. Erfarenheter från Irakoch Afghanistan har inneburit att USA utvecklat en specifik doktrin för counterinsurgency(FM 3-24) respektive stability operations (FM 3-07). Detta indikerar att det föreligger enskillnad i de två begreppen.Syftet med uppsatsen är att undersöka och definiera skillnader i begreppen COIN(upprorsbekämpning) och stabiliseringsoperationer. Medlet för att nå syftet utgörs av enjämförande studie av amerikanska doktriner.

Mathematics is a central topic in today?s society. There are many different approaches each teacher has their own way. In this essay, I compare four teachers? mathematics teaching in two different countries with regard to ways of learning, particularly in the four operations.

Among those who graduate from the various schools of Social work in Sweden are a great majority women. At the same time men are sought after in the work field.  But not just to level up the equality between the sexes, but also to fill a gender specific niche to counter up a need for male role models. But a closer look at this need and the types of functions set to cater for it shows that male role models as a concept vary between contexts. In this study we examine the concepts and the practices of male role models in three different settings: a municipal social care center offering young boys male bonding activities; a non-profit organization warding young people from drug abuse and criminal behavior; and last, a long term residential home for young boys between the ages 13 and 19. Our research shows that the concept of the male role model vary between the organizations and less so within.
