This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

Syftet med denna uppsats är att undersöka med vilka grunder det direkta flygunderstödetunder ?Operation OVERLORD? genomfördes. Min undersökning studerar USAAF (UnitedStates Army Air Force) och dess flygunderstöd i den europeiska delen av andra världskriget.Detta innebär att uppsatsen avgränsas till det direkta amerikanska flygunderstödet på deneuropeiska arenan.Mitt intresse för ämnet väcktes i somras när det var exakt sextio år sedan landstigningen vidNormandie genomfördes. Detta uppmärksammades stort med olika evenemang. Som flygareär det av naturliga skäl särskilt intressant vilken roll flygstridskrafterna spelat i olika insatser.När landstigningen genomfördes under sommaren 1944 var andra världskriget inne på sittfemte år.

AbstractThis paper is a study in press reception with the intent to examine how twelve female actionheroes have been portrayed in Swedish media between 1974 ? 2006. The purpose is to discern patterns and differences in how the female movie character is received by their contemporary journalists and to relate their views to social and gender related theories. The female actionhero is an independent and brutal character, often alone and without a mother or a child. This separates her from typical female roles, which historically been characterized by passivity, fear and dependency on the male characters in the movie. The female actionhero as a character opens up for complex reception. One perspective in the research identifies the independent woman as a feministic icon.

In today's society it has become increasingly important for organizations to take into account non-financial values. Sustainability reporting involves reporting the economic, social and environmental aspects of an organization's operations. The trend has been towards an all the more scrutinizing society with an increasing demand for transparency and translucency. A greater focus on environmental issues has also contributed to sustainability?s increasing importance as a topic.

As competing organizations struggle to become more effective, one field stands out as one of the vital keys to success; internal communication. Even small errors in information handling can end up into obstacles that seem impossible to overcome. Managers constantly need to adjust the internal communication to fit variables that mirror the structure of the organization. This thesis is a study about how and in what magnitude structure affects organization?s internal communication.We have done qualitative interviews with McDonald?s and Diesel, two different global organizations within the branch of service business.

Using interviews conducted within the municipality of Nam Dich, Vietnam, this qualitative study explores how ethnic minority parents and children navigate around the state's supervision in order to preserve their traditional practices of child marriages. Moreover, the research explores the roles and expectations between individuals within an ethnic minority family as a collective unit. Using governmentality supported by the concept of state evasion, culture bearers and empowerment, I argue that understanding child marriage as a phenomenon requires analysis of cultural context. The paper starts with an introduction of the ongoing relation between the Vietnamese state and ethnic minority traditions related to child marriage. While the Vietnamese state ?s modernization projects aim to empower individuals by creating more freedom within the process of marriage and increasing the opportunity for education and work, certain ethnic minority groups want to uphold their cultural ways of marriage when parental arrangement occurs from an early age.

AbstractA European identityA study of Manuel Castells criteria?s to create a European identityC-Essay in Political Science, by Helena Saagpakk, August 2007Supervisor: Björn ÅkerbergPhilosophers and visionaries dreamt early on the idea about a united Europe. This dream was destroyed by the two world wars during the first half of the 20th century. The first community was established in 1950 after the Second World War. This was the beginning of a peaceful cooperation between the member states, and the community later developed into the European Union.

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

Background: In the past 10 years private label has increased significantly in the Swedish grocery market. This is an important strategic event, which is a great challenge to suppliers as it causes stiff competition. To handle this situation an increasing number of suppliers have to make the decision whether to produce private label or not.Purpose: The purpose of this study is to find and analyse factors that influence suppliers in the Swedish grocery market to produce private label. On this basis we intend to confirm or develop existing theories within the field of study.Research method: The study has a qualitative approach where empirical data has been gathered through interviews with suppliers and retailers in the Swedish grocery market.Results: This study has identified factors that underlie suppliers? decision to produce private label.

With an estimated 250 ethnic groups, Nigeria, no doubt, has been grappling with the problem of pluralism of ethnic nationalities. It is not news in Nigeria that extreme ethnic consciousness of its citizens has led to the victimization of one ethnic group by another. This victimization has come in the form of exclusions in the distribution of both wealth and power in the country.Amidst all the exclusions, the unity of the country has been ironically regarded as sacrosanct, and should not be negotiated. It is often said that fate brought all the ethnic nationalities in order to form one great country. I subscribe to this belief that fate brought us together for the above purpose, especially now that several countries around the world are merging in one way or the other to form a formidable force to reckon with both politically and economically.

In the western world, strokes are the third most common cause of death, hitting mainly the elderly population. Smoking, high blood pressure, diabetes and overweight are known risk factors for causing strokes. Previous studies show that an increased level of particulate matter, PM, is also related to an increased number of strokes. The population in this study consists of patients over 65 years old who live in Malmö. Levels of particulate matter were measured from October 2004 to April 2005 at a central outdoor monitoring site in Malmö.

Introduktion: Sekretorisk media otit (SOM) är den vanligaste öronsjukdomen och uppkommer oftast i efterförloppet till akut media otit (AOM). Om barnet får SOM leder det till hörselnedsättning som kan påverka språklig utveckling och ge beteendeproblem. Etiologin bakom SOM anses vara multifaktoriell. Barnets tryck i mellanörat kan påverkas vid flaskmatning. Allergier, bakteriella/virus infektioner och inflammationer har också betydelse för utvecklandet av SOM.

Svenska Lantchips is a Swedish SME sized snack manufacturer. Being a small, medium sized, family-owned business with branches throughout the world, they make an interesting company for a case study. The case study I have conducted focuses on the internationalisation process of this family owned company ? how they, despite their size, find ways to keep up an unique business structure, designed for internationalisation.The aim of this essay is to compare Svenska Lantchips? internationalisation process with traditional internationalisation theories and see if these are compatible with this company. The theories used are The Uppsala Model, The Network Model, and The Born Global Theory, with The Born Global Theory representing the younger generation of models.After undertaking an in-depth interview with Michael Hansen, business developer at Svenska Lantchips, I collated a substantial amount of material, which I have used as the basis of this essay.

Rapid Granulator is one of the world's largest producers of granulators, which is a kind of grinderwho grinds discarded plastics to granules which later can be reused when pressure molding plastics.The company wanted help in developing a new, or alternatively extending their previous,measurement equipment. The old equipment was hard to use, required changes in the code fordifferent measurement scenarios and had a limited array of measuring quantities. Rapid had an ideaof a similar concept only with a greater number of input ports, better range of applicable sensors andan advanced yet easy to use interface. The system is supposed to be placed at Rapid's test departmentwhere it will be used as a tool for finding faults and provide data which can be used for furtherdevelopment of the granulators.The project's members accepted the task and immediately began searching for suitable componentsfor the system. After the search was completed a list of costs, limitations, sensors, I/O's anddevelopment environment was presented to Rapid's staff.

Background Atelectasis is a commun respiratory complication related to general anesthesia and may contribute to pneumonia and acute respiratory failure. Atelectasis apear within 10 minutes after anesthetization and occur in 90% or more anesthezied patients regardless of age and gender. The aim of this study was to indentify if there are any evidence for which methods are ultimate or are most efficacious to reduce and prevent the formation of atelectasis.                                                                                                          Methods This study is a descriptive litterature study where 28 scientific studies have been indentified for review and analysis.                                                                                                               ResultsThe use of 100% oxygen during the induction of anesthesia favors the developement of atelectasis. This can be prevented by preoxygenation with oxygen content of 100% combined with a PEEP of 6-10 cmH2O. When free airway is secured, oxygenation with 100% was found to be unnecessary.
