Introduktion/Syfte. Intresset för och användandet av adhesiv cementering av keramiska material har ökat under de senaste åren. Detta har lett till ett ökat intresse att kunna jämföra olika studiers resultat med varandra och därmed har även intresset för att utveckla internationella standarder inom forskning ökat. Syftet med denna studie var att jämföra den adhesiva bindningsstyrkan mellan ett laboratorieframställt material innehållande kvartsmjölsförstärkt epoxyresin (Sipoxy), med emalj och dentin. Detta för att avgöra om Sipoxy kan användas som en standardiserad ersättning istället för tänder i in vitro studier som utvärderar bondade keramiska rekonstruktioner. Material & metod.

When Vladimir Putin in the year 2000 came to power in Russia many believed that the Russian civil society were weak and had very little influence and with Putin people say that the situation have deteriorated. The purpose of this paper is to establish what kind of relationship exists between the Russian state and the civil society and to analyze this from a top-down perspective. We are looking at Russia during Putins first term in office from the year 2000 until 2004. In order to establish the relationship we have used John S. Dryzeks theory of inclusive and exclusive state and whether it?s active or passive in this process.

The aim of this study was to examine the aspect of power in the relationship between the personal assistant and the disabled person he or she works with (the user). The study was based on interviews with five personal assistants who worked for private companies that provided personal assistance. Seven themes were identified and discussed. These were: the users amount of control over the assistance given, the workplace environment, the working conditions, the organization of personal assistance by private companies, the assistants recourses and usage of power and the users participation in chores. To analyze these themes I used Foucault's theory of power and the perspective of Human Resource.

The main theory and method used is critical discourseanalysis signed Norman Fairclough.

Civil-military relations ? conditions for cooperationAbstract: Civil-military cooperation is a branch of current interest, both in studies and research. The importance has also increased after the government´s demands in a more developed and efficient coordination of national contribution to international peace support operations. Several studies show that there is a lack of ability to cooperate between different levels of command and other actors. The Swedish tradition of state administration is strong and the responsibility to cooperate lies within the hands of the different authorities.

SammanfattningSyfte och frågeställningar. Syftet med denna studie var att på äldre personer studera olika fysiologiska parametrar före och efter en period på åtta veckor med styrketräning som utförs tre gånger i veckan. Frågeställningarna var: Hur påverkas statisk och dynamisk maximal styrka i främre lårmuskulaturen av styrketräning? Är det någon skillnad i resultat mellan koncentrisk och excentrisk styrka i lårmuskulaturen före och efter styrketräningsperioden? Är det någon skillnad i förändring mellan benstyrka uppmätt med isokinetisk teknik jämfört med uthållighetsstyrka och ett kort funktionellt benstyrketest? Hur påverkas maximal syreupptagningsförmåga registrerad via submaximalt cykeltest respektive vid pyramidtestet av träningsperioden?Metod. I studien deltog 20 generellt ej påtagligt aktiva män och kvinnor i åldrarna 66-79 år.

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.

This essay will focus on drug addicts and the world as they see it. The essay is based on intervjues with three men and one woman and participant observation of the three men´s social life in the surroundings of Stockholm. The informants? opinions and experiences are central as well as the observations made of them during an intensive fieldwork. The study which was of an exploring character has revealed a complex relationship between the informants and society.

This study is made in cooperation with Setragroup AB. Setra is Sweden?s biggest sawmilling company with a turnover of almost 6 billion SEK. 45% of the produced volume goes to the Swedish market where the customers are the DIY-sector and industrial customers. Setra as well as the other Swedish sawmilling companies operate in a very competitive environment.

ABSTRACT Background: Health and ill-health are multifaceted concepts. Previous research has shown that physical activity and the level of cardio respiratory are important parts of leading a healthy lifestyle. Possibly, it?s so important that the Occupational Health Service should focus even more on this.Aim: The aim was to investigate if there was a relationship between the level of cardio respiratory fitness and self-rated health, and between the level of cardio respiratory fitness and physical and mental ill-health.Method: The study was conducted using a quantitative method in the form of a cross sectional study. Data was collected from an Occupational Health Service, containing answers to a questionnaire on work environment and health and test values ??from completed cycle fitness tests.

The invisible entrepreneurship is a study of owners of businesses with foreign heritage. It describes the unexplored relationship between ethnicity and class within this group of entrepreneurs.The result of the study is a model which I have found to be suitable to use when depicting the relationship between the ethnic profile and class. The model indicates that the importance of ethnicity decreases as both the owner of, and the business reach a more prominent class. The method of collecting data has been interviews with owners of businesses and Grounded theory has been used to analyse this data. Theories on ethnicity, owners of businesses with foreign heritage, and class in relation to ethnicity have been discussed on the basis of social constructivism.

The globalisation of the world is believed by some to homogenise individuals from different national cultures. However, the values and norms of an individual are deeply rooted in their national culture and are therefore difficult to change. Since birth these values and norms are learnt through interaction with others within a specific national culture. The differences in values of a national culture are shown in the cornerstones of the nation. These cornerstones are language, aesthetics, religion and social institutions.

Fifty employees at a local industrial company answered a questionnaire about coping strategies and personality traits. One purpose of the study was to investigate if officials and public employees used different coping strategies in stressful work situations. Another purpose of the study was to investigate if there was a relationship between the personality traits of the officials and the public employees and their chosen coping strategies. Ten Item Personality Inventory and Brief COPE were used to examine personality traits and coping strategies respectively. The results showed a difference in exhibited personality traits where conscientiousness was higher among the official employees than the public employees.

This study was conducted on a property with a thinning machine team. The purpose was to investigate in which machine, the harvester or the forwarder, that caused most damage to the trees in six different stands. Different factors, related to the damage frequency in the stands, were checked out. For example: basal area per hectare, thinning strength, tree diameter and the rate of production. The harvester drivers were also interviewed about how, when and why stem damages occur and how to minimize them. The study stated that 4.3 percent of the trees were damaged. Out of these 88 percent was caused by the harvester and the rest, 12 percent, by the forwarder..

Det här arbetet studerar med hjälp av en attitydundersökning förhållandet mellan anställdasoldater och Försvarsmakten i syfte att utveckla förståelsen för soldaters commitment till sinarbetsgivare. Frågeställningen lyder Hur ser soldaters relationer ut till arbetsgivarenFörsvarsmakten? Arbetets teoretiska grund hämtas i begreppet relationship commitment och närmare bestämtden del som benämns attitudinal commitment. Den begreppsdefinition som nyttjas bygger ihuvudsak på Meyer och Allens (1991) tre komponenter av relationship commitment, det villsäga affective commitment (känslomässig), continuance commitment (kalkylativ) ochnormative commitment (normativ). Begreppsdefinitionen inkluderar även åtta påverkansfaktorer som var och en ges en tydlig knytning till respektive komponent avrelationship commitment.
