Hållbar utveckling i förskolan, med fokus på återanvändning
Syftet med examensarbetet var att undersöka hur förskolor arbetar med hållbar utveckling i förskolan. Studien har utförts med strävansmålen inom området naturvetenskap och lärande från förskolans läroplan (Lpfö 98, rev. 2010) som bakgrund. Genom intervjuer med pedagoger har vi studerat hur olika förskolor arbetar med hållbar utveckling. Genom observationer med barn, där vi har varit deltagande genom att utföra två olika experiment, har vi tagit del av barnens kunskaper och tankar kring återvinning och återanvändning.
Produktion av Pyrolysolja från kvistrejekt
Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting. Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.
Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure
A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.
Kassaflödesanalys i mindre aktiebolag: En flerfallstudie inom träindustrin i norra Sverige
Alla aktiebolag är skyldiga att upprätta en årsredovisning. Beroende på bolagens storlek ställs olika krav på redovisning av kassaflödesanalys i den externa redovisningen. Kassaflödesanalys är en sammanställning av ett bolags kassaflöden indelat i olika kategorier. Den visar intjänade likvida medel, men även hur dessa har tillförts. Kassaflödesanalys är något som också kan användas i den interna styrningen av bolag för att få kontroll över kassaflöden och kunna prognostisera samt följa upp utfall.
Automatiserad mätning av kvalité : Varför är inte all mätningautomatiserad?
AbstractThis bachelor?s thesis at the Department of Production Engineering at the Royal Institute of Technology in Stockholm deals with the subject of automated metrology. The degree of automation of tasks within production has been a growing trend but the measurement of quality has not followed the same trend. The main thesis follows:What incentives are there to automate the measurement of quality in production?What factors are crucial and why are not all metrology automated?The thesis comes along with a number of sub-queries and delimitations.The working method includes both theoretical and empirical studies.
Bibliotekariens nya arbetsmarknad
The purpose of this thesis is to examine why graduates in librarian- and information science are employed by private companies. An initial explanation could be the influence of information technology and its impact on the librarian. A second factor relates to how employers regard the librarian outside the confines of the traditional labour market. The study is primarily based upon qualitative interviews with representatives of Swedish companies who have employed librarians since 1993, the year that the education achieved third level academic recognition. Theoretically we relied upon Manuel Castells discussion on the rise of the information society and its influence on companies and the labour market.

Unified Flow Sensor
Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.
Utökade tillämpningsmöjligheter för turbinlösning i våtpartiet hos tissuemaskiner : Konceptförslag som möjliggör tillämpning av turbinlösning för maskiner vars banbredd är bredare än 2,9 meter
AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.

En studie i hur järnvägens möjligheter kan appliceras inom AB Volvo : med hänsyn tagen till företagets logistikkrav
In the year of 2011, the new CEO of AB Volvo announced a major reorganization. This reorganization was a contributing factor to the start-up of this thesis.Volvo Group Logistics Services (VGLS) is Volvo Group?s global logistics partner, which designs, manages and optimizes all of the group's incoming and outgoing logistics flows. With the reorganization, VGLS started a project regarding responsibilities around railway flows. Within the project a demand to collect logistics requirements occurred.
Unesco, Malraux och ombildningens museum : Estetik och kosmopolitik i efterkrigstid
An inquiry into the post-war European aesthetic and political landscape should take the international organization Unesco?s colour reproductions and travelling exhibitions of paintings into consideration. In these, the organization implements André Malraux? idea of the ?imaginary museum? as a framework for a future cosmopolitical, aesthetic (and utopian) community. During the late 1940?s, the Swedish government also discusses the need for raising an ?aesthetic awareness? amongst their citizens as a consequence to a poor knowledge in the fine arts.
?Killar skriver inte puttinuttigt? : En experimentell studie av genusföreställningar i textbedömningar
This thesis examines conceptions of gender revealed by people when assessing texts. The research questions are: What associations can be discerned between gender conceptions and ideas about the quality of texts? What features of content and style are perceived as female or male? The study seeks to develop a method for comparing different people?s assessments of the same text. The material was collected by means of questionnaires in which 114 informants were asked to assess three anonymous student texts and then guess the sex of the writer. The material has been analysed quantitatively by correlating the assessments of the texts with the guesses about the sex of the author, and qualitatively, as the informants? freely worded assessments of the texts were analysed for content and form with the support of assumptions about how assessments are expressed in text.
Fosforavskiljning i reaktiva filter vid småskalig avloppsrening
An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.
Småvatten då och nu : en förändringsstudie av småvatten i Skåne och deras kväveretentionsförmåga
Wetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas.The number of wetlands in Scania have, due to the intensified agriculture been reduced to maximize the area suitable for crops.However since the mid 80th the consequences of this has been acknowledged, and many wetlands have been restored.This master?s thesis aim to see what impact this development have had on wetlands in Scania over the last 60 years. And also look at some of those factors important for the efficiency of nitrogen removal in wetlands. During the process a detailed manual for inventories of this sort was created.The material used to execute the inventory of wetlands where aerial photographs over Scania from the 1940th, 1980th and 2000.
