Ekonomisk styrning och kostnadskontroll vid IT-outsourcing
Background: Many companies have outsourced their IT-operations and their expectations of what this IT-outsourcing will contribute to the business are high. Cost cuts are not always a natural outcome of IT-outsourcing. Many companies that have outsourced their IT-operations consider it to be problematic and complex to exercise management control and reach cost control which was the purpose of the IT-outsourcing. Purpose: To describe and analyze what affect IT-outsourcing has on a company?s management control system and a company?s possibility to exercise cost control.
Finansiering av små tillverkande företags tillväxtmöjligheter i revitaliseringsfasen : Finansieringsprocessen
In 2014-2015 a large-scale Ebola epidemic occurred in West Africa. The Swedish Civil Contingencies Agency was given the order to conduct the Swedish response. The purpose of this case study was to investigate the impact on project planning of the three factors: the nature of the crisis, political initiative and developing countries. In this case study the crisis was an epidemic, and the project was initiated by the Swedish Government and conducted in two developing countries. The results were intended to contribute to developed understanding and recommendations for future project managers in similar projects.
Integrerad arbetsprocess mellan projektör och konstruktör, För effektiv och kvalitetssäker projektering med Tekla Structures och SAP2000
The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
Utformning & placering av vädringskanaler i ett passivhus, drivet av naturliga krafter
A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.
Psykosocial arbetsmiljö bland chefer vid kommunala vård - och omsorgsboenden : - en intervjustudie
Introduction: First line managers in the public sector, are under a great pressure from both senior management, leadership, politicians and often from a large group of employees. Few studies have been made on the first-linemanagers psychosocial work environment, even though in the studies found that the manager affects their employees work environment.Aim: How first line managers in municipal elderly describes the psychosocial work environment on the basis of demand-control - support model.Methods: The study was conducted through individual interviews with six first line managers. Respondents were recruited through a strategic selection in a medium-sized municipality in Västernorrland. The interviews were conducted using an interview guide. Qualitative content analysis with an deductive approach was used as a method of interpretation of the results.Results: First line managers point out the difficulty in balancing the requirements and several managers also mentioned the importance of having clear role descriptions and objectives.

Quality is the key to a well executed product or service. The construction industry hasn?t highlighted the quality in recent times which have contributed to the construction industry receiving much criticism in the field. The public sees it as an offhanded industry where errors and delays are common.The reason for this is considered to be primarily the lack of time, constant pressure to reduce costs and skills and the ability to communicate between the parties about what the correct quality really means. The industry has begun to realize that it must start setting clearer standards and that there are great opportunities for improvement.This report will give Peab an opportunity to develop their quality work.
Development of Liquid Cooling for PCs
In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.
Sjuksköterskans trycksårspreventiva omvårdnadsåtgärder - En litteraturstudie
Syfte: Syftet med föreliggande litteraturstudie var att beskriva vilka omvårdnadsåtgärder sjuksköterskan kan använda sig av i det trycksårspreventiva arbetet. Syftet var även att granska urvalsmetoden som de inkluderade artiklarna har använt sig av.Metod: Artiklar publicerade mellan 2007 och 2013 söktes i databaserna CINAHL och PubMed. Resultatet baserades på tretton artiklar.Resultat: Resultatet utmynnade i fyra kategorier: 1) Riskbedömning; med användandet av ett riskbedömningsinstrument i det dagliga omvårdnadsarbetet minskade förekomsten av trycksår. Det framkom att sjuksköterskans kliniska blick var viktig för att upptäcka patienter med risk för att utveckla trycksår. 2) Tryckavlastande underlag; användande av tryckavlastande underlag var en viktig åtgärd för att förebygga uppkomst av trycksår.

The purpose was also to investigate whether there were any differences in action between the emergency room nurses who had worked longer or shorter period than two years with this.Method:The design was quantitative, comparative and descriptive. Surveys were distributed to 30 nurses who worked in the emergency room at a Swedish hospital.
"Konflikter bidrar till en levande verksamhet" : En kvalitativ studie om ledarskapets inverkan vid konflikthantering i privat och offentlig äldreomsorg
This study is based on interviews with four managers in public elderly care and four managers in private elderly care. The aim of this paper is to examine how these managers are experiencing their leadership in relation to conflict management, and if the managers leadership differs depending on private or public elderly care. Leadership and conflict management are theories that have been used in order to analyze the empirical findings. Previous research that has been used in the study concerns ?leadership/leadership styles?, ?conflict management?, ?to be active in the private/public elderly care?.

The nurse's role is to support and help the family to find meaning in the difficult situation and to provide realistic hope. Balancing between the patient's and the family's needs is difficult. Knowledge about how nurses experience difficulties in the interaction with family is required in order to grant good care too critically ill patients and their family-members.Aim:To describe nurses' perceived difficulties in the interaction with family-members of critically ill patients.Method:The study is a qualitative literature-based study based on qualitative research. Results: The analysis resulted in four main themes; difficult disunion, environmental constraints, interpersonal difficulties and communicative difficulties.
Oljefilmens tjocklek mellan kolvring och cylinderlopp
Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremostwithin applications in the industry. These motors have several sliding contacts, one of these, isthe contact between piston ring and cylinder bore. The radial piston hydraulic motors advantageis to produce high torque in very low rotation velocity, this result in that the maximum slidingvelocity between piston ring and cylinder bore, during the whole stroke, is very low. Theconsequence of this low sliding velocity is that the contact between piston ring and cylinderbore, during the whole stroke, is bound to the boundary lubrication regime. This result in, thatthe piston ring is exposed to wear, thus affect the service life of the complete hydraulic motor.To minimize wear of piston ring, it is essential to determine the oil film thickness between thepiston ring and cylinder bore.
