The purpose of this work is to find out if the suctionvalve to the salivaejector for dental equipment in a simple way can be improved or if a new design is needed. The result of the examination of the suctionvalve shows that the friction between the piston and the seal is high and that this causes the valve in a few cases sheaves. The study concluded that only small changes in material or detail, improve the component..

Business incubation is an important force of economic development but relatively unheard of in organization theory. This is partly due to the fact that in organization theory, meta-organization or the organization of organizations has been neglected or left lagging as much theorization has been focused on organizing individuals. With the growing number of business incubators, and meta-organizations in general, the need for understanding a relatively new type of organization is prevalent.This case study of the business incubator Global Business Labs Botswana (GBL) aims to clarify the organizational differences among meta-organizations and traditional organizations on a case level, as well as explain the underlying factors for these dissimilarities. With respect to the nature of this case study no general conclusions are drawn from the results. The inference, however, is that the organization of GBL and its incubated companies differs from the traditional organization in five elementary aspects: the weak hierarchical structure, the operational autonomy of its members, the strong focus on recruitment processes, the member identity and the lack of formal sanctions.

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

The area around the stream Orsundaan, which runs trough the valley Harsbacksdalen, is famous for its beautiful landscape. The upper area of Orsundaan and Harsbacksdalen is situated just south of Heby in Uppland, Sweden. Even though the area is protected by different nature conservation acts, it is difficult to find any information about the geodiversity in the area. Geodiversity, or geological and geomorphological diversity, includes the concepts of geoprocesses and geoelements. Very high geodiversity could be seen at an inventory of the geomorphology in the upper area of Orsundaan and Harsbacksdalen.

Swedish pre-school teachers are in the middle of a debate regarding a form of general school competence that today is criticized by mass media. The training and skill development that is used today is an important tool in the development of the organization as well as the people that work in them. This study aims to explain how this training actually is performed and the opinions of the pre-school teachers that actually finish the training. Previous research in this area has primarily been focused at the types of methods that exists from an executive standpoint. This study, instead, aims to shift that focus to the individual worker.

The purpose of this paper is for the reader to realise how national innovation systems are deeply intertwined with the legal background of a country and to understand the processes that involves national innovation systems specifically regarding the stem cell / genetics research and how the need for specific community law must be considered targeting the stem cell patents. The legal part will try to answer: Why is it important given the actual state of the European stem cell national innovation systems for the European Commission to take a stand and tackle issues regarding the patenting of the human stem cell innovations? This is done from a country industry analysis (business approach) and then linking it with competition law from a community stand point of view (that tackles biotechnology issues). In order to achieve this the paper is divided into three separate analyses beginning with a theoretical background of general biotechnology / genetic terms that will enable the reader to have a general understanding of the importance of this kind or research ( genetics / stem cell research). The chosen countries case studies exemplify very diverse economies and development perspective from the traditionally R&D intensive to the least and from the biggest countries in Europe to one of the smallest, thus giving cultural, legal, economic and scientific variety..

Stress uppstår när det sker en obalans mellan vad som krävs av individen och de resurser som hon har tillgång till. Arbetsrelaterad stress är något som allt oftare förekommer bland lärare idag. Denna stress kan bland annat vara orsakad av ökat ansvar samt tillgänglighet för eleverna. Socialt stöd från omgivningen är en viktig faktor för att reducera stress. Denna studie syftar till att undersöka betydelsen av socialt stöd och skolrelaterad kontext (stökig och ostökig) för kvinnliga och manliga lärares upplevda stress.

Syftet med detta examensarbete var att undersöka vad som motiverar de som volontärarbetar inom fritid och hälsa samt att se om motivationerna skiljer sig beroende på tid som volontär. En webbenkät med frågor tagna från Volunteer functions inventory (VFI) och Basic need satisfaction at work scale (BNS) skickades ut till 220 volontärarbetare för att få svar på frågorna: Vilka motivationsfaktorer är bäst uppfyllda hos volontärarbetarna och förändras dessa över tid? Resultatet visade enligt VFI att Värderingar, det osjälviska hos människan, Förståelse, viljan att söka nya kunskaper, och Förstärkning, egenutveckling, har högst värden hos volontärerna. Vad gäller BNS så visade resultatet att Kompetens, förståelse för och delaktighet i sin omgivning, var bäst uppfyllt följt av Samhörighet, upplevelsen att tillhöra en viss social miljö. Enligt VFI har tiden som volontärarbetare inget samband med motivationsfaktorerna medan BNS visade att alla faktorer minskade men motivationsfaktorn Samhörighet sjönk mest.

Background: Pressure ulcer is a complication that arises often due to a lowered general condition. Pressure ulcer arise because of long term compressive load application. That?s why it?s of utmost importance as a nurse to work in preventive ways, as the pressure ulcer lead to physical, psychological and social consequences for the patient. Purpose: The purpose was to describe the patients experiences of living with pressure ulcer.

This study examined some contradictive results in a report from the Swedish board of Integration. The contradiction was concerning the Swedish populations dismissive judgments of experience a shared ground of values between the Swedish society and those witch are generally held within Islam. These dismissive judgments were given at the same time as the population reported to have a lacking knowledge of Islam in general. To test for psychological aspects of these contradictions, the analysis was based on the theoretical ground of Social Identity Theory and Theory of Attributions. The study used an existing survey that examines people´s estimations of their own and other members of society´s fulfilling of democratic values.

Stress and burnout are two words that are commonly occurring in many contexts today. More and more people experience that they are stressed and that they does not feel well. The long term sick -leave increases as a consequence of people being burned out. These phenomena prolong over all ages, sexes, classes and professional categories, which probably means that the construction industry would not be spared.  In the construction industry, stress and bad health are no new phenomenon, already during the 1970s and big parts of the 1990 s, the construction sector were exposed to the phenomena.A sector that has a large turnover annually cannot presumably be faultless.

The subject of this master level thesis in historical osteology, is a study of waste management in the medieval town of Lund. The aims of the study is achieved through looking at the taphonomic aspects of bonefragments from the quarter Blekhagen. The study is divided in two separate sections, one that is a litterature study of what is known about waste management, and another one that contains a taphonomic and spatial analysis. Through examination of the taphonomic variables weathering, average weight and trampling and a spatial analysis, I am able to deduce that there are signs of controlled waste management in the material. It is not possible to draw any general conclusions about waste management in the medieval town however.

Vattendirektivets (2000/60/EG) krav på skydd och bevarande av vattenkvalitet i vattenförekomster har kraftigt ökat medvetenheten om vattenhänsyn och vattenvård i det svenska skogsbruket. Världsnaturfonden lanserade hösten 2011 tillsammans med skogsägarföreningarna (Södra skogsägarna, Mellanskog, Norrskog och Norra skogsägarna) vattenhänsynsverktygen NPK+ (Naturvärde, Påverkan, Känslighet och Plusvärde) och blå målklassning som hjälpmedel till skogsägare för att ta och synliggöra vattenhänsynen. Relevansen hos verktygen NPK+ och blå målklassning att identifiera och klassificera vattendrag efter vattenkvalitet undersöktes med antalet fiskarter som indikator på vattenkvaliteten. 55 vattendrag i Krycklanåns avrinningsområde strax utanför Vindeln i Västerbottens inland inventerades med NPK+ och blå målklassning i mitten av september 2011. Fältinventeringsdata analyserades statistiskt med fiskartsförekomst från en tidigare elfiskeinventering i vattendragen.

The purpose of this essay is to find out what experiences three preschool teachers, two preschool directors and a social worker (BSc) from the social service have of reporting suspicion of child abuse done by preschools. What perceptions do these individuals have of each other, what experiences do they have regarding cooperation and how do they perceive their responsibilities regarding filing reports on suspicion of child abuse? This investigation is based on qualitative interviews with open ended questions on the basis of an interview guide. The theoretical approach of the essay lies in the phenomenology philosophy, which revolves around the individual?s experiences and perceptions of a phenomenon.

AbstractThe aim of this present study was to investigate whether there is a relationship between birth order and the personality trait narcissism using 181 individuals from Finnveden High School in Värnamo (115 females, 60 males, mean age 17, sd=0,94), in the context of the proposal of Sulloway (1996) that personality is influenced by the specialized nich-es siblings adopt in the quest for access to parental resources. A questionnaire which in-cludes Narcissistic Personality Inventory test, Birth order test and also Rosenberg?s self-esteem test in order to investigate if it might has an impact on narcissistic personality trait, was used. Results showed that there was no significant relationship between birth order and narcissism, however, a significant relationship between narcissism and self-esteem was found. Furthermore, there was a significant relationship between narcissism and the individual?s relationship with the mother.
