Energianalys av tryckluftsystem : så kan Billerud Skärblacka AB spara energi på tryckluft

Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

?Män är från Mars och kvinnor är från Venus? : Könsroller, kroppsuppfattning och självkänsla hos ungdomar

Syftet med föreliggande studie var att undersöka om det fanns könsrollsskillnader i kroppsuppfattning och självkänsla utifrån könsrollerna maskulinitet, femininitet ochandrogynitet, om det fanns samband mellan kroppsuppfattning och självkänsla och även omdet fanns skillnad mellan könen gällande de två variablerna hos gymnasieelever (n = 79). Könsroller mättes enligt formuläret Bem Sex-Role Inventory SE ? BSRI-SE,kroppsuppfattning i enlighet med skalan Body-Esteem Scale for Adults and Adolescents ?BESAA och självkänsla enligt Rosenberg Self-Esteem Scale ? RSE. Resultatet visade attmaskulinitet korrelerade positivt med kroppsuppfattning och självkänsla. Vidare fanns ettnegativt samband mellan femininitet och kroppsuppfattning och självkänsla och gällandeandrogynitet fanns ett positivt samband med självkänsla.

Utredning om en ökad biologisk behandling av matavfall i Halmstads kommun

Environment and sustainable development are very current topics in today's society, bothnational and international. The government's bill 2004/05:150 ?Swedish environment objectives - a common commission? contains several environmental quality objectives, that in turn is divided up in smaller secondary objectives. One of the secondary objectives says: ?Latest year 2010 shall at least 35% of the food waste from households, restaurants, largescale kitchens and shops be recycled through biological treatment.

Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

Skyltar i verkstadsmiljö : Informationsdesign och Rumslig Gestaltning i ett förslag på utformning och placering av ett representativt skyltsystem

Under våren 2008 utförde jag mitt examensarbete på Utvecklingsverkstaden, inom Volvo Construction Equipment i Eskilstuna. Uppdraget bestod i att presentera förslag på ett skyltsystem som skulle vara modernt, professionellt utformat och ha ett enhetligt utseende. Den befintliga skyltparken var kraftigt eftersatt och föråldrad.  Syftet formulerades till att utforma förslag på ett tydligt skyltsystem som skulle representera aktuell avdelning och dess verksamhet. Syftet innefattade även att ta fram övergripande riktlinjer om placering, för varje kategori av skyltar.

Rättvisemärkning av snittblommor på den svenska marknaden :

Trade is the driving force for economic development. A greater equity in international trade can improve the livelihoods and the well being of producers in developing countries. The small-scale farmers have limited resources and have difficulties to get access to the international market. As a result of this, the Fair Trade movement has been developed and has now formed a trading partnership between the producer and the consumer. This study analyses if the Fair Trade movement can be a way for the workers in developing countries to achieve more justice in their production manner in the international trade of cut flowers and continue to be an important competitor of these products, but with better livelihood conditions. My method has been to do a comprehensive literature study of the Fair Trade movement, in which I describe the certification process, and the market of Fair Trade in Sweden.

Påverkas mosippa (Pulsatilla vernalis) negativt av igenväxning?

Pulsatilla vernalis is one of several endangered plant species that benefit from wildfires and small scale disturbance events that repel competing vegetation and create open patches in the vegetation cover. Previous studies argue that Pulsatilla vernalis is decreasing in numbers due to vegetation changes associated with the decrease in wildfires, forest grazing and changes in forest management. In this study, 17 populations of P. vernalis were inventoried in order to examine if soil and/or vegetation structures affect the population structure of P. vernalis (i.e.

Kroppsuppfattning hos unga kvinnor: en jämförelse mellan gymnasieelever i Luleå och Jokkmokk

Det perfekta kroppsidealet gör sig ofta påmind i samhälls- och mediadebatten. Dagens västerländska kroppsideal domineras av en smal och fettfri kvinnokropp. Under tonåren är fokuseringen på kroppen mer påtaglig än under någon annan del i livet. Strävan efter det slanka idealet är svårt att uppnå och kan medföra att individen inte förmår att acceptera sin kropp. Syftet med denna studie var att få en bild av och jämföra kroppsuppfattningen hos unga kvinnor som går på gymnasiet i Luleå respektive Jokkmokk.

Undersökning av elektroniska scorekort på golfmarknaden : Var ligger problemet för fortsatt utveckling?

This is a Master´s Thesis based on my own idea instead of that of a company. It is a survey that focuses on finding out more about which part of the development process that is blocking the establishment of electronic scorecards on the golf market. Why has it not been introduced on the market in a larger scale yet, considering the technology we possess today? This question is investigated through interviews with the Swedish Golf association, and three companies that have chosen different paths to implement an electronic scorecard. The interviews focuses on finding out what developers and the association believe to be the main problem, before taking the next step in releasing electronic scorecards on a larger scale.

Jämförande studie av LEM2 och Dynamiska Redukter

This thesis presents the results of the implementation and evaluation of two machine learning algorithms [Baz98, GB97]based on notions from Rough Set theory [Paw82]. Both algorithms were implemented and tested using the Weka [WF00]software framework. The main purpose for doing this was to investigate whether the experimental results obtained in [Baz98]could be reproduced, by implementing both algorithms in a framework that provided common functionalities needed by both. As a result of this thesis, a Rough Set framework accompanying the Weka system was designed and implemented, as well as three methods for discretization and three classi cation methods. The results of the evaluation did not match those obtained by the original authors.

Skapande av organisationskunskap i små, unga forskningsintensiva företag : En studie av tre företag i Uppsala

Because of among other things the globalization and a focus on core competencies knowledge has become very important for the companies of today, especially for research-intensive companies. The problem is that the companies become more sensitive to how knowledge is created and spread, that is, how organizational knowledge is created. Especially sensitive are companies who are small, young and research-intensive. The purpose with this thesis is to explore how organizational knowledge is created in small, young and research intensive companies.The theory is based on a five-phase model of organizational knowledge creation and four modes of knowledge conversion described by Nonaka and Takeuchi (1995). These concepts constitute the foundation of the analytical model used in the thesis.The study is carried out by qualitative, highly structured interviews with low standardization.

Högskolestudenters akademiska self-efficacy : Hur relaterar kön, KASAM och socialt stöd till studenternas upplevelse av studieframgång?

 Tidigare forskning inom studentliv och studenternas framgång är ett väl undersökt område. Könsskillnader, känsla av sammanhang (KASAM) och socialt stöd är några av de faktorer som har visats påverka studenternas akademiska self-efficacy. Studiens syfte var att undersöka relationen mellan kön, KASAM, socialt stöd och studenternas akademiska self-efficacy. 124 högskolestudenter i Mellansverige deltog genom att svara på en enkät bestående av College Academic Self-efficacy Scale, Social Support Questionnaire 6 (SSQ6) samt Sense of Coherence scale (SOC-13). Materialet analyserades med Pearsonkorrelation, regressionsanalys och t-test.

Inneklimatundersökning : Hur fungerar ventilationssystemen i två större lokaler och hur ser kommunikationen kring detta ut mellan hyresgäster, hyresvärd och projektör?

This examination paper is a study of the indoor climate in a theatre and a practice room for orchestras placed in Sickla in Stockholm. The designer of the ventilation system wondered if he had managed too make a good environment for the users and he also wondered which of the rooms that had the most desirable climate. The project includes polls for visitors, interviews of people connected to the rooms and measurements of the physical environment. The results show a small dissatisfaction about the thermal indoor climate, it?s a little bit to cold and the air draws.
