Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

Studiens syfte var att, med utgångspunkt i ett designteoretiskt multimodalt perspektiv, beskriva, analysera och tolka hur tre förskolepedagoger designar lärandesammanhang, kring ämnet matematik. Förutom detta var också syftet att få insikt om hur lärandesammanhangets design kunde förstås och tolkas i termer av lärande och meningsskapande. Den metod jag valde var uppbyggd kring en icke-deltagande videoobservation med ett kvalitativt upplägg där målet var att försöka förstå det som ägde rum genom relevanta tolkningar. I resultat och slutsatser framkom det till exempel att förskolepedagogerna använder en mängd semiotiska resurser och teckensystem i form av fysiska redskap tillsammans med ansiktsuttryck, tal och handrörelser i kommunikationen med barnen. Dessutom framkom det att barnen också använde sig av ett antal olika semiotiska resurser och teckensystem i arbetet med att skapa mening kring de olika lärandesituationerna.

Envirotainer builds containers that are specialized in transporting of temperaturesensitive products these containers are customized for airplanes. The containers arethen leased to other companies, most often to pharmaceutical companies.Envirotainer are based in Lagga, Knivsta. It is also here where the production of thecontainers is held. The container RAP T2 was designed in the early 80ies. The RAPT2 contains a fleet of about 1220 containers spread all over the world.

Syftet med litteratur studien var att beskriva vilka studier som har gjorts med fokus på ?grön omsorg? /utemiljö i vården av personer med demens, samt att beskriva personalens upplevelse av dessa omvårdnadsåtgärder och eventuella effekter på de boende. Litteratursökningar gjordes i databaserna Medline och Chinal, och resulterade i nio inkluderade studier. Resultatet visade att flertalet av studierna hade som syfte att studera utemiljö och boendes välbefinnande och beteende. Sex studier hade en icke-experimentell design, två studier hade en kvasiexperimentell design och en studie var uppdelad i två delar varav den ena delen hade en icke-experimentell design och den andra delen hade en kvasiexperimentell design.

The present study investigates the relationship between narcissism, using identified facets in the five-factor model for the grandiose and vulnerable narcissistic personality, and job performance. The results, based on analyses of correlations from previous studies, meta-analyses and norm-data, show general differences regarding the grandiose and vulnerable narcissistic facet profile and their respective relationship to job performance. The results confirm previous study implications of the facet level data?s ability to capture aspects of the personality that a broader measure misses. Similarly, the results demonstrated that facets could differentially predict job performance in both a negative and positive direction.

My questions at issue for this report has it´s beginning in the growing problems of thenegative effects of burning fossile fuels and the rapidly growing energyprices.1. Is it possible to design a micro scale powerplant?2. Is it economically interesting for a potential customer to by such a product?The aim with this report is therefor, with the help of design work and calculations, to answerthese questions and to create a platform for building a fully functional micro scale powerplant.The material used in the report is mostly product catalogs from various industries but alsostudy course littrature about steam engines.The result of the report is that it is fully possible to design a fully functional micro scalepower plant.

In the summer of 2009 the High Line opened in New York, a park built on an out-of use elevated rail viaduct. The park meanders its way through the buildings and allows the visitor to see the city from a totally different perspecive than we are used to.I have made a Design proposal in Eriksdalslunden, Stockholm, with inspiration from the High Line. The proposal is based on design ideas of a park I logically call the Low Line, as the place isn't elevated as in New York, but lowered. The two places have some similarities, mainly the strong urban identity and the tracks crossing both areas. They also have very obvious differences, above all the fact that Eriksdalslunden is situated in a swale and is defined in a third dimension by the high bridges that crosses the area.The High Line is designed by James Corner Field Operations, and they have been working using their motto 'Keep it Simple, Keep it Wild, Keep it Quiet and Keep it Slow' during the whole process, words that normally aren't associated to Manhattan.

This thesis is about sustainability within chemistry, the so-called, green chemistry. With this work  I seek to combine green chemistry with sustainable  development  and find methods for teaching green chemistry in a laboratory environement.  I have designed  and tested two labs with ingredients of green  chemistry and sustainable development in my study. I wanted to determine if my design model  leads to conception for the students. The students have through forms and interviews declared their perspective on the education and their conception. In a laboratory environment the pros of a laboratory way of work should be recognized.

Companies of today are facing a development where it is more significant to focus on existing customers since the approach constitute a more cost reducing way, compared to finding new customers. During the last decades the marketing has therefore moved towards a relationship based marketing. Companies emphasize creating long-term relationships with customers, instead of consider the sale as a non-recurrent phenomenon. To engender customer loyalty has been an essential objective in the creation of long-term relationships.In this essay the authors have chosen to do a study which enlighten how companies in the ready-made apparel business produce added value to their brand and through this generate customer loyalty. Through a case study we analyze how Filippa K, Tiger of Sweden and Gant do to maintain value in their brand, in both a business- and customer perspective.

Inom hållbar design har man under senare år börjat härma naturen för att hitta nya lösningar på människans problem. Naturens ekosystem fungerar som praktiska modeller för kretsloppsfungerande miljöer där energi och material tas om hand ? precis som visionen för den hållbara staden. Genom att dels förstå ekosystemets uppbyggnad, dels övergången från ekologi till design, kan man efterlikna ekosystem i den urbana miljön. Designstrategin biomimik är en tillämpning av detta förhållningssätt, där man efterliknar naturens processer i arkitektur.

Mängden elavfall ökar och kommer att fortsätta att öka en tid framöver. Elektriska och elektroniska produkter innehåller en mängd olika ämnen, i vissa fall upp till 60 olika grundämnen. En del av ämnena är giftiga eller farliga och en del är väldigt värdefulla. I t.ex. mobiltelefoner står ädelmetallerna för 93 % av värdet.

Resultatet visar även att en designprocess är olik från gång till gång men att det finns vissa riktlinjer som kan hjälpa en designer genom processen på ett kontrollerat sätt..

Officially, the EU gender policy since 2000 has been guided by the strategy of Gender Mainstreaming. This strategy aims to promote gender equality and is informed by a feminist ontology which stipulates that women are structurally subordinated.In this essay, I examine whether the European Commission has adequately adhered to this gender policy in its free trade negotiations with the ACP (African, Caribbean, and Pacific) countries as part of the Cotonou Agreement. As a result of my text analysis of documents related to the negotiations, opinion pieces by interested actors and policy papers of the EU, I find that the Commission does not act in accordance to its stated gender policy.To explain this discrepancy between policy intent and actions, I employ postliberal feminist theory and Robert Putnam's Two-Level Game Theory Model. By analyzing statistics and published research, I explore how gender issues are being represented politically on a domestic and international level.My findings show that a key cause of this discrepancy lies in the low levels of female participation in the political institutions of the EU and ACP; a lack of participation that is especially pronounced in the area of international economics. In explaining the constraints on female participation and the prospects of full implementation of the EU's gender policy in the international political economy, I emphasize the role of culturally and historically gendered institutions..

This essay studies the practice of both the political and the administrative leadership at the municipal level from the point of view of the politicians and the chief officers leadership role, and the relationship between politicians and administrators. I discuss and analyse how politicians and senior officials practice leadership, differences or similarities and if their practice of leadership raises any challenges in a democratic framework at the municipal level. I conducted interviews with the municipal political leader and the head of administration at the municipal level in Karlshamn and Sölvesborg. In the analysis I discuss communication as a leadership process which highlights ?enabling elements? and potentials of the leadership process.

This study is based on the public eldercare assistances administrators and unit managers perspective. The purpose of this study is to describe and understand how the assistance administrator and unit manager approach elderly needs, who can be harder to accommodate as well as alternative providers that also can meet the needs of the elderly. It is important to gain more knowledge about how assistance administrators and unit managers look at these aspects, what their attitude and approach is towards them. This is important to learn more about because the assistance administrators and unit managers have discretion in their work and the power to change and affect the elderlys situation in a significant way. They decide on actions and design implementation to meet the needs of the elderly and enable them a reasonable standard of living.The choice of method used in this study was qualitative through semi-structured interviews, conducted with assistance officers and unit managers.
