Förbättring av väggfäste för flatscreens
The project was carried out in cooperation with the department of product development IOS at IKEA. The work included improvements of a new existing product that Ikea soon will release on the market, Observatör, a wall bracket for flat screens. The product is supposed to fulfil the needs within this market for IKEA. However, since Ikea was not satisfied with it, our work was to carry out the improvements that were specified in the beginning of the project. Another task in the project was to develop a side-product that is supposed to be used together with Obeservatör for storage of DVD/decoders.The project included labour as problem definition to final technical drawings and a prototype.
Reglering av turbins ledskenor i vattenkraftverkmed hjälp av elektriska ställdon
Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.
Val av överlastskydd för elektriska ventilmanöverdon på kärnkraftverket i Forsmark
At nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..
Det Omedvetnas återkomst : En tvärvetenskaplig litteraturstudie i fältet mellan psykoanalys och neurobiologi
There are differences today amongst psychoanalysts regarding if psychoanalysis should limit itself to being exclusively a hermeneutic discipline or if psychoanalysis should find points of contact with neurobiology. The purpose of this essay is to touch upon the larger issue that creates the different points of view: Can psychoanalysis become enriched by finding points of contact with neurobiology, and should psychoanalysis be regarded as belonging to a broader scientific field than being exclusively a human science? The question at issue is: Can modern neurobiology contribute to a development of the psychoanalytic concepts; compulsion to repeat, transference/countertransference and talking cure? The method used is a literature study. The result shows that: Freud?s theories regarding traumatic compulsion to repeat can be linked with LeDoux?s theory of "emotional memory".

Preventiva trycksårsåtgärder. En litteraturstudie
Trycksår kan förekomma på alla typer av vårdavdelningar och tar lång tid att läka samt är en stor kostnad för samhället.
Syftet med litteraturstudien var att undersöka åtgärder för trycksårsprevention.
Metoden är baserad på en modifierad version av Forsberg & Wengströms modell för en systematisk litteraturstudie. Sökning i databaser PubMed och CINAHL utfördes och resultatet i litteraturstudien grundades på nio kvantitativa vetenskapliga artiklar. Författarna kunde identifiera olika preventionsåtgärder där framför allt evidensbaserade bedömningsinstrument som Modifierad Nortonskala och MNA-SF är viktiga att använda i trycksårsprevention, men även temperaturmätning, ?Continental anal plug? (CAP), god nutrition, aktivitet samt tryckreducerande underlag som fårskinn..

I fokus står improvisationernas musikaliska ?språk? ifråga om musikaliska byggstenar eller strukturer.
ST-läkares identitetsarbete: En studie av läkare under specialiseringstjänstgöring
The results from 13 interviews and one opinion poll answered by resident physicians were interpreted as stories about identity as primary material for this thesis. The resident physicians stress the importance of considering whether their work primarily concerns curing people from diseases or if the process of working with sick people also includes how to handle the pressure of work, either by adapting to it or changing it, and the search for balance between work and private life. Residents separate themselves from older physicians by saying that younger physicians accentuate empathy to a greater extent while older physicians emphasise a high work load. Identity seems to effect how the residents perceive and relate to their work, themselves as residents and different types of patients..
Studenters förhållningssätt till valet av framtida bank
Since the middle of the 1980´s the Swedish bank market has experienced a change concerning structure and pressure of competition. Before the year 1985, the market was characterized as a market with few operators but have changed to a market with many operators and seen as one of the most intense in Europe where the four major banks; Nordea, Handelsbanken, SEB and Föreningssparbanken together have a strong position. Their market share has recently decreased, mostly for the benefit of foreign banks and niche banks. The Swedish market has experienced difficulties in generating profits which mostly depends on new establishments that have increased the pressure on competition, a low growth as well as weakened customer relations. The development has resulted in a growing importance of market segmentation, mainly by the fact that costumers have become more disloyal as a result of the increased competition.Students are a market segment of interest for the financial market, mainly because of the expectations of their positive financial situation in the future.
The effect of hoof trimming on dairy cows´ behaviour, locomotion and production
The Swedish dairy production today consists of big farms and different housing systems are in use. These systems put demands on the cows? ability to cope with the environment and one challenge is the claw health in the herds. Some claw lesions that are frequently observed are foot rot, hemorrhages, digital dermatitis and sole ulcers, which can be caused by, for example, the claws? environment and the flooring type used.
JB-TOTALSONDERING : Jämförande sonderingar och utvärdering av egenskaper i isälvsavlagringar kring Igelstaviken
The main purpose of this thesis has been to find a way to evaluate the soil parameters for the Total sounding method (TS), such as the inner friction angles and settlement modules. This study only includes an analysis of soil profiles from the Stockholm region. The chosen location for the study is a proposed residential area east of Igelstaviken in Södertälje. Presently, the subject plot is located in a residential area and is also adjacent to a school area.Total sounding is originally a Norwegian soil testing method. The differences between the sounding methods (weight-, ram-, CPT-sounding) are for instance how the sound is driven into the ground and what kind of parameters that are registered.
Elevers känslor och tankar om betyg i år 9
Marks do not only work as an acknowledge of the effort that has been made under a long period of time, but also as a receipt for eligibility to further studies. Within the political debate, marks have often caused a big discussion among the political parties. That is due to the obvious difference between the political parties on the left, and their counterparts on the right. However, there is one thing that they all have in common. Everyone of them have plans of measure within their political agenda, regarding the use of marks.The aim of this study has been to try to understand the way pupils think about marks.
