Igensättning av övre spalten i centrifugalpump
This report focuses on the upper slit. The upper slit is located between the impeller andthe drive unit. The slit design depends on pump type and application. However it isuncertain why the design varies, The purpose of this report is to clarify why the designvaries and to recommend an improved slit design.A research has been done; information was gathered from interviews, but also fromsearching of databases and studies of drawings, reports and documents. The originalpurpose of the slit was to prevent twining around the driveshaft, and prevent dirt fromentering the cooling system.
Sommargården - Hållbara uppvärmningsalternativ för stugbyn Sommargården, Finnhamn
Finnhamn is a group of islands that are located in the middle north part of Stockholm?s archipelagos. On the main island Stora Jolpan there is a camp called Sommargården, which consists of eleven different buildings in various sizes. The assignment given by the Archipelago foundation (Skärgårdsstiftelsen) is to analyze if it?s benefited to replace Sommargårdens current heating system that consists of electricity radiators, with a more energy efficient heating system. This research is done with help of the literature review and a visit to Finnhamn in order to map Sommargården?s current state and its energy usage.
Indelning av trakter inför gallring på Holmen Skog : en utvärdering av svårigheter och möjligheter
A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.
Centrala begrepp i socialtjänstens LVU-utredningar : en dokumentanalys
The main purpose of this essay was to study how the social service and the lawcourt have implemented the UN Convention on the Right of the Child, particularly incorporating the childs best interest in social services, child welfare investigations and the lawcourts judgement. We considered how the needs of the child, and the will and view of the child was documented. Also how the parents capacity and the environment factors, were documented in the social services investigations and the lawcourts judgement. The study was based both as a literature study and a document analysis. We analysed ten child welfare investigations from a social service office and their belonging lawcourt judgements.Our conclusion of the study is that the child is in focus both in the investigations and in judgement.
Digitaliserade möjligheter för skolan : En studie av två spels pedagogiska potential för historieundervisning i grundskolan
This essay examines computer and video games and their capacity of being useful in teaching sessions. Focus is being put at a possible pedagogical potential and how it is being expressed in games mechanics.

Ytstridsfartygs ballistiska skydd mot finkalibriga projektiler
This paper is about the extent to which simplified penetration calculations ofsmall-caliber projectiles is a useful tool for assessing the physical protectioncapability. The work should be seen as an attempt to create an accessible tool inthe form of a simplified equation that allows for a better and safer use of thenaval vessels. The tool will also be used at different levels so that decisions andinstructions could be clearer.Performed calculations show a very limited capacity of a ship's basic design interms of physical protection against the use of small-caliber projectiles.How do we know that the calculations correct? By verifying the calculations withpractical shooting tests, a substantial condition to answer the question will becreated. To shoot against a material with two different thicknesses estimated toproduce perforation and non-perforation is a good approximation of the equationusability in the context..
När livets pump förlorar kraft : en litteraturstudie om hjärtsviktssjukas upplevelser i det palliativa skedet
Bakgrund: När hjärtat förlorar pumpkraft eller förmågan att fylla kamrarna tillräckligt med blod uppstår hjärtsvikt. Tillståndet är allvarligt och frekvensen av insjuknanden förväntas öka. I många fall är prognosen sämre än vid flera cancersjukdomar. Den palliativa vården är idag främst koncentrerad på avancerad cancer. Forskning visar på att patienter med svår hjärtsvikt har jämförbara upplevelser med de som insjuknat i avancerad cancer, men erhåller inte den vård som svårt cancersjuka får i ett palliativt skede.Syfte: Syftet var att belysa hjärtsviktssjuka patienters upplevelser av att vara sjuk i det palliativa skedet, för att med detta som grund utveckla god vårdkvalitet för denna patientgrupp.Metod: Systematisk litteraturstudie med kvalitativ ansats.
Delaktighet i vardagsysslor : En kvalitativ studie om personer med lindrig utvecklingsstörning på ett gruppboende
The purpose was to describe the significance of participation concerning leisure time and household duties for persons with mild intellectual disability living in a group home with some support from caretakers. Interviews were performed with five persons, two men and three women, living in such a group home. The questions in the interview guide had an open character and were divided into four different areas, leisure time, economy, cooking, cleaning and laundry. The results indicate that all informants felt they participated in all four areas. Further on, the results show there was participation of three different kinds.
Motorikens betydelse för inlärning
AbstractMy purpose with this study is to find out if it helps children who have diffuculties with their concentration if they get to practise their motor behaviour knowledge during their day at the school to promote their learning capacity. My purpose is also to find out how schools works with motor behaviour training. To get answers to my questions have I done interviews with four educationalists and I have also used books and internet sites. Motor behaviour is of importance to how children learn things in the school, without a well working motor children gets difficulties to sit still and to concentrate. The children may put their energy at the wrong things in the classroom, when the energy instead should be need to learning things.
Lägesbild : Problemområden vid skapandet
Within the framework of the concept of Network Based Defence (NBF) services should be available in the network, in order to increase the aggregate capacity. A common situation picture is one of these services.The aim of this paper is to answer the problem "What are the main problem areas in the creation of a situation picture in the land arena, with the help of the technical sensors that exist today?" and to develop a basis for continued research in the field situation in the concept Networking Enabled Command, Control and Collaboration (NEC3) at JCDEC (Joint Concept Development and Experimentation Centre). To answer the problem, a descriptive method is to be used in descriptions of the land arena, the information arena and the sensors and a deductive method is used when analyzing the asensors in the land arena.The problems that exist in the creation of a common situation picture, is that different types of obstacles makes it difficult for the sensors, the large number of people who are not combatants and that it is difficult to judge if a civilian vehicle is a threat, then it could be driven by civilians or by combatants..
Gynnar eller motverkar kommunerna kostnadseffektiv miljöstyrning : en studie av kommunala taxor och avgifter
Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals.
The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.
Utvärdering av förbättrad metod för objektiv kvalitetsbedömning av spermiemotilitet hos hingst :
In this trial we used QualispermTM as an objective method of measuring stallion semen.
Samples of semen were analyzed before and after centrifugation. Motility and concentration
were statistically analyzed. During the trial all the objective mesaurments were compared to a
subjective method.
The advantages of QualispermTM compared to older CASA- systems is it´s ability of
measuring a greater amount of spermatozoa while it also grades them into different
subpopulations. These subpopulations have different qualities that decides their capacity of
fertilization.
The results showed that this objective method might be used practically. Although, there are
still some disadvantages, such as high costs and the necessarity of accurat training of the
handler.
If it´s possible to prove further relevant results that also are statistically correct, this could
prove the usefulness of QualispermTM as an objective measurment method in the daily work
at gestuts and stallion stations, thus giving the staff a reliable instrument in assisting the work
for an improved horse breeding in Sweden, improving both in quality and economically..

Vem de vill att du ska vara : Enhetschefer om brukares önskemål gällande kön och etnicitet hos hemtjänstpersonal
The purpose of this study was to assess which basic principles collide when home care service users have requests about how their help is going to be performed. The requests involve gender and ethnicity of the personnel. The study is based on the experiences and reflections of the managers regarding this issue.As the study is focused on the reflections of the managers, I have used a qualitative research method based on interviews. I have also used two case examples as a compliment (vignettes).I was interested to explore how the managers reasoned and argued about gender and ethnicity of the personnel, and their importance in home care situations. I have investigated whether it is considered to be appropriate that the service users chose if a man or a woman helps them in intimate situations (such as showers), and if they are entitled to refuse to receive home care services from people with a different ethnic background.
