matematikämnets egna språk : En kvalitativ studie av förståelse för och missförstånd kring geometriska begrepp

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?.

Direct-EGR tillämpat på HCCI

The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

Att leva med högkänslighet

Högkänsliga personer sägs registrera fler nyanser i sin omgivning än andra människor och även bearbeta och reflektera kring intrycken på ett djupare sätt. Därför kan de också ibland bli överstimulerade av alla sinnesintryck. Syftet med denna studie var att undersöka vad det kan innebära att leva som högkänslig. Med hjälp av kvalitativa intervjuer som hölls via chattprogrammet Skype samlades information in från elva högkänsliga personer. Samtliga deltagare var medlemmar i SFH, Sveriges Förening för Högkänsliga.

Att vårda en närstående i hemmet vidlivets slut : En livsberikande erfarenhet?

Background: Peripheral arterial disease (PAD), as a consequence of atherosclerosis in the arteria of the limbs, affects one of ten Swedes older than 65. PAD can develop slowly and silently, and involves an increased risk for cardiac infarction and stroke. Measurement of the patient´s ankle blood pressure and calculation of the ankle-brachial index is an evidence-based method to discover PAD. Objective: To investigate how district nurses and general practitioners perceive this method of examination and experience possible obstacles to why it is not more commonly applied at primary health care centres. Method: Data collected by semi-structured interviews have been processed by qualitative content analysis with a manifest onset.

Girls just wanna have fun - Tjejers rätt till tjejgrupper

The purpose of this essay is to examine how girls groups, particularly in school, can help girls with feelings of stress and pressure they can experience in their everyday life. We also want to examine how girls groups can be used, and explain why they should be held in school and not only in other organizations. The information we?ve gathered comes from books and websites that cover the subject. In addition to this, we?ve also handed out surveys and implemented interviews with both younger girls with girls groups experience, a teacher and a youth recreation leader. The theoretical aspect of this essay stems from two different theories: Labeling theory and Strain theory.

En del av spelet : En studie av fotbollsdomarnas tillvaro i Gästrikland

There is a clear difference between the way football players and leaders regard the role of the referee, compared to the way the refereeing body looks at it. The refereeing body regard themselves as fundamental for the existence of the sport, while the other mentioned parties merely see them as functional justice makers. This view places the referees outside the field of football. This establishes a football culture, which is conflicted when it comes to the role of the referees on the field. The conflict comes to its edge in youth football, where the referees are under severe pressure.

The effect of hoof trimming on dairy cows´ behaviour, locomotion and production

The Swedish dairy production today consists of big farms and different housing systems are in use. These systems put demands on the cows? ability to cope with the environment and one challenge is the claw health in the herds. Some claw lesions that are frequently observed are foot rot, hemorrhages, digital dermatitis and sole ulcers, which can be caused by, for example, the claws? environment and the flooring type used.

Hänsyn till mark och vatten vid slutavverkning : en fältstudie på känsliga marker

The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines. This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments. The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done. The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..

Karaktärisering av hårdmetallpulvrets råvaror och dess påverkan på pulvrets flödesegenskaper

This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.

Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

Valberedning och tillsättning av styrelse enligt Svensk kod för bolagsstyrning: En studie av könsfördelning ur ett institutionellt perspektiv

Since July 2005 the major companies listed on the Swedish stock exchanges are required to apply the Swedish Code of Corporate Governance. The code states that companies shall have a nomination committee responsible for nominating new board candidates and seek to obtain gender equality in the Board of Directors. This paper examines the trend of board as well as nomination committee composition among Sweden's 60 largest publicly traded companies between 2005 and 2008. Our overall finding is that neither the board nor the nomination committee composition has changed to a notable extent during the period and that the share of newly appointed female board members has actually decreased. However, the trends vary between different sectors.

Turbinkretspump system - Kraftvärmeverket i Borås

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.
