Förutsättningar att utforma stationsbatterier i vattenkraftverk med Li-jonteknik
In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.
Trygghet och trygghetsskapande i arbetslivet
In this paper we examine what security is to the individual and how the individual creates and maintains security in their work. The purpose of this paper is to study how the creating of security in working life is performed. We conduct six semi-structured qualitative interviews with permanent employees in the private sector and we encode our material using thematic analysis. We analyze our material and illustrate our problem area on the basis of Anthony Giddens's theory of ontological security and give examples of how security and creating of security is performed at the empirical field with previous studies in the research area. Our survey shows that security for the individual at work seems to be about having continuity in everyday life, financial stability, a permanent employment, a challenging and fun job and a family in good health and good living.

Utformning av förfrågningsunderlag vid totalentreprenader
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
Hur naturfilm berättas : Narrativa strukturer och verklighetsbeskrivning i naturfilm
In our attempts to understand the world, wildlife films play a significant role. Wildlife films help us to see new places and learn about animals in remote locations, that we otherwise wouldn?t be able to do. Yet wildlife films have throughout history been criticized, mainly for the ambivalent relationship between science and storytelling. While the films give us a scientific impression and say something about the ?reality?, they clearly have the intension to amuse, capture and entertain their audience.
Golfbollstvätt
During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

Arbetsmotivera mera! : En kvantitativ studie om arbetsmotivation på Norstedts Juridik
Syftet med denna studie var att utvärdera arbetsmotivation på företaget Norstedts Juridik och att ge underlag för förbättringsarbete. Utvärderingen gjordes med hjälp av en modell för arbetsmotivation, som konstruerades med grund i teori och tidigare forskning. Modellen innefattade åtta dimensioner som tillsammans antogs utgöra arbetsmotivation. Dessa dimensioner var variation, autonomi, signifikans, feedback, utvecklingsmöjligheter, tillhörighet och lojalitet, lön och belöningssystem samt work- life balance. Dimensionerna analyserades i förhållande till de tre bakgrundsvariablerna kön, anställningstid och arbetsenhet och resultaten behandlades i statistikprogrammet SPSS.

Vision Nollenergihus : Energiförsörjning av passivhus med sol- och vindenergi
Climate change is the modern society?s common issue. The developed countries areconsuming more than what is sustainable, and the climate change due to the use offossil fuels can be seen clearly. EU has specified goals, in order to stop furtherdamage, which demand that every member state have to reduce its energyconsumption by 20 % before 2020 and 50 % before 2050, relative to 1995.The Swedish government uses a number of instruments to encourage reduction in theusage of energy, but every individual has to contribute to reach the goals.With increasing energy price the cost of living is going up. A lot of people are lookingfor ways to save energy and not be affected as much by the increasing price.Investments for insulation, replacement of windows and replacing old heating systemfor a new efficient heat pump is getting more and more common.This thesis is about investigating the possibilities in becoming independent from buyingenergy for households.
Utveckling av instyrningsfunktionen hos ett dockningsinterface
In this project the task has been to develop a product that will facilitate an operation for personnel working in a sterilization center. The operation is to steer the front of a loading trolley into the chamber of an autoclave, a so-called docking. The moment is complicated because the margins to deviate from ideal docking position and still succeed, is very small.The principal Getinge's desire was that the product could be retrofitted at the customers on their existing systems. One of the demands was that the product should fit two types of trolleys, one with a adjustable working height and one with a fixed working height. Getinge is supposed to purchase the system from a subcontractor who shall manufacture it and the requirement from Getinge is that the cost of purchase mustn't exceed SEK 500Initially principles, solving the problem was developed.
Vi-kan-ju-banken - Hälsorelaterat förändringsarbete i arbetslivet
With starting point in the increasing ill-health in Swedish working life today, in form of for example absence due to sickness and early retirement pension, and the knowledge that the working environment effects peoples health in a big extent, I found it very interesting to inquire into how people within the working life experience health promotion and how this can be developed. A qualitative method was used to receive a deeper understanding for the employees? experiences and data was collected through semi structured interviews with employees on a bank called Ikanobanken, in Älmhult. The result shows, among other things, that respondents find responsibility and the opportunity to influence the learning processes and development important. It also became clear that the respondents find participation, motivation, communication and safety essential factors when related to changes in health behaviours.

Isaac Newton och den matematiska naturfilosofin
In several scientific and technical educations today we meet mathematical studies in differential- and integral calculus. The classic mechanics is a foundation for the physics and it has made it possible for today's technical developments that we in our everyday life meet and make use of. The intention for this essay is to give a picture of the person behind this discoveries that changed the science and the world. Besides the purpose to bring the reader on a journey through Isaac Newton's life the main intention is to give an understanding of the way he discovered the binomial theorem, the differential- and integral calculus, the numerical methods Newton-Raphson's and Newton's interpolation-polynomial, Newtons identities and his classification of third-degree curves and elliptic curves. A derivation of Kepler's first law is also included..
