There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.

The interest for functional strength training in golf has grown the last decade and scientists are always trying to find training stategies to improve the biomechanical aspects of the swing. Kinematic sequence contains a proximal-to-distal sequence order towards impact, and an effective kinematic sequence in the down swing begins with a rotation in the pelvis and follows by an activation in thorax, arms and club in the respective order. The rotational torques in the proximal segments wanders through the body and to the more distal segments to create an effective energy ? and power transfer at impact. The x-factor stretch is the seperation between the rotation in the pelvis and the thorax at the top of the back swing and at the beginning of the down swing.

This thesis explores and compares the former armed opposition groups; Mozambique National Resistance (RENAMO), Front for the Liberation of Mozambique (FRELIMO) and South West Africa People's Organization (SWAPO) transformation processes into political parties. The first question addressed is; What factors determines the ability of these armed opposition groups to transform into political parties after armed conflict? The question is addressed through four structural and organizational factors; international involvement, the organizations ideology and identity, their ability to change inter-elite relationships and their ability to change collective incentive strategies. The second question addressed is if the transformations process can affect the parties? degree of institutionalization? The degree of institutionalization is examined through the party's adaptility, complexity, autonomy and coherence.

The purpose of this bachelor degree thesis is to analyze technical issues associated with an implementation of a low sloping trash rack with narrow spacing. A hydropower plant in Umea?lven was used as a case study. The basis for the study was a model where trash racks were dimensioned for inclinations between 25 and 45 degrees. Corresponding head loss, durability and water speed through the rack were then determined for each inclination.

In published studies it is found that the fuel consumption on a forwarder is relatively constant, on time basis. A certain variation between different sizes of forwarders occurs as well as between different working elements. The aim of the study was to establish a forwarders comparatively fuel consumption when driving on road and in the terrain, loaded and unloaded, with high and low gear and with high and low speed as well as with hydrostatic and hydrodynamic transmission. A hypothesis was that low rpm gives lower fuel consumption on distance basic, at all trials. The test driving was made with a Hemek 750 which is a three geared hydrostatic machine and with a Hemek 700 which is a hydrodynamic machine with six gears.

Aren?t you tired of never finding stuff? Take a bits as example, do you store these lose in your toolbox or carpenter belt? What if you could have it all accessible and assembled in a tool, always at arm?s reach?Today bits are used together with electric screwdrivers and handheld screwdrivers in a greater spread. For these different types of storage, from pure storage boxes to complex tools with storage built in, exist. The professional craftsmen commonly use some kind of box where the bits can be stored. Even so they tend to store their bits loose in a carpenter belt or toolbox, since they want the speed and accessibility of carpenter belt over the storage box?s tidiness.The project was started in the fall of 2010 and a referents group was early put together to ensure that the developed product became as user-friendly and attractive as possible.

Syftet med denna uppsats var att försöka förstå och tolka hur lärare i grundskolans tidiga årskurser tycker att mediepedagogik fungerar i praktiken. Jag ville föra fram lärarnas röster kring mediepedagogikens innebörd, olika arbetssätt och varför mediepedagogiken behövs i dagen samhälle och därmed i skolan. För att förmedla lärarnas tankar och erfarenheter valde jag att arbeta utifrån en kvalitativ metod och empirin har samlats in genom intervjuer. Resultaten analyserades utifrån tidigare forskning kring ämnet samt Zygmunt Baumans samhällsteori med fokus på flytande moderniteter, sociala gemenskaper och det tertiära lärandet. Resultatet visade att det är svårt att definiera vad mediepedagogik är och eftersom begreppet har olika betydelse för olika personer är det svårt att beskriva varför det är viktigt.

Entreprenöriell self-efficacy är en viktig faktor inom entreprenörskap som kan antas ha ett samband med stress. Den aktuella studien syftade till att undersöka sambandet mellan prediktorerna rollstress (role ambiguity, role conflict och role overload), generell stressupplevelse, ålder, stöd från omgivningen och kön samt den beroende variabeln entreprenöriell self-efficacy. Även könsskillnader undersöktes. Fyrtiotre nyblivna företagare besvarade enkäterna som skickades ut via e-post. Multipel regressionsanalys visade att ålder, kön, role ambiguity och generell stressupplevelse kunde predicera entreprenöriell self-efficacy.

Today?s companies offer their products and services through multiple distribution channels in an increasing extent, in order to reach bigger markets and more customers. Multiple channels result in an increased risk for channel conflict.This essay is an exploratory and descriptive study with the purpose to explore some companies? channel conflicts on the basis of sales commission and price differences. A case study has been made at two different companies and the empirical material has been collected with qualitative interviews.We found more channel conflicts in the company that uses sales commissions than in the company that doesn?t.

ADHD (attention deficit hyperactivity disorder) is a phenomena that is much talked about in both schools and in communities. Today, there is a conflict surrounding the diagnosis ADHD. A part of the conflict takes part between the sociologist Eva Kärfve and Christopher Gillberg, professor in child- and teenage psychology. The roots of this conflict surrounds the much debated line of what is seen as normal and ?too? different, basically how many children that actually should have the diagnosis.

Logistik är mer än transporter mellan olika platser. Stor del av ett företag och dess logistik kretsar kring de interna logistikfunktioner och hur de som företag ständigt jobbar för att förebygga flaskhalsar. En lagervariant som används för att skapa ett högre värde i en kedja är ett så kallat cross-dockinglager. I ett sådant förs ständigt ett arbete med att effektivisera processer med hjälp av olika tekniker och strategier. En teknik för att öka omsättningshastigheten i ett lager genom snabbare identifiering och spårning av gods som hanteras är Radio Frequency Identification (RFID).Syftet med studien är att belysa de ständigt återkommande problemområden som uppstår i ett cross-dockinglager samt hur en RFID-lösning skulle kunna stödja dess verksamhet.

This essay is a study of the Swedish author Amanda Svensson?s novel Hey Dolly (2008). The aim of the study is to investigate the conflict that occurs in the storytelling because of the untruthful narrator Dolly. Using the terms story and discourse, from a method of narratology by Maria Nikolajeva, the purpose is to analyze how the narrator manipulates the reader?s comprehension of what is real and not in the text.

Människan är en social varelse som har behov av andra människor men eftersom vi är olika uppstår det ibland konflikter. Måste konflikter vara negativa? Kan det komma något bra ur en konflikt? Studien vill lyfta fram konflikter som något som kan ge motivation och kreativitet till att skapa förändringar. Studien vill se om det finns något samband mellan konflikter och innovationer. Studien vänder sig till medarbetare, företagsledare, och studenter.

In this study we try to focus on the costs for wear parts on different type of soil tillage machines and at Väderstad Rapid drilling machine. We have studied some of the leading types of cultivators and disk harrows. Among the cultivators we have investigated Väderstad Cultus, Dalbo Dinkomax, Horsch Tiger and Terrano. At disk harrow we have looked at Amazone Catros and Väderstad Carrier. We have made more detailed study on costs for wear parts, working depth, driving speed and diesel consumption.

Konflikter finns överallt i det dagliga livet. De existerar inom individer, mellan människor, inom organisationer, mellan olika grupper och länder. Denna uppsats fokuserade på interpersonella konflikter och de olika sätt individer väljer att hantera dessa konflikter. Huvudsyftet var att undersöka konflikthanteringsstilar hos svenska studenter samt att se på skillnader mellan kvinnor och män. Ett instrument kallat Thomas-Kilmann Conflict Mode Instrument har använts i studien för att mäta i vilken utsträckning studenter använder sig av olika konflikthanteringsstilar.
