Hur miljövänlig är dagens optikerbutik, och hur miljövänlig kan den bli?
SUMMARYEnvironmental issues are currently a hot topic of debate. Studies within the optics branch have not specifically been conducted previously, so the aim of this study was to determine the extent of environmental-awareness specifically within this branch.A survey, consisting of questions relating to environmental issues, was distributed to 100 randomly-selected opticians in Sweden. Of these 100 surveys, 64 were returned and showed a varied branch-engagement for environmental issues.Results of this survey showed that opticians were best in sorting newspapers, magazines, other paper and hazardous waste. Metal and rigid plastic were not sorted to any larger extent.Choosing environmentally-safe products was not so popular and only six stores always do this. 25 shops turn off electrical machines and equipment over night; while the majority of the remaining stores leave the machines on during the night.27 stores did not know if their electrical company provided ?green electricity?.Results showed that there is a lot of work to be done in making the stores more environmentally friendly.
?ÄNTLIGEN!?- En lysrörsarmatur för det egna hemmet
The aim of our study is to ascertain whether a hanging suspension fluorescentlamp for a private home environment is going to be attractive for a largeaudience. We want to open up for new uses of fluorescent lamps as lightsources.The main approach in this work is how to design a fixture with fluorescentlamps as a light source that will meet the requirements and requests of thehome environment could look like. At the same time we want to make a newimpression of how a fluorescent light source.Primarily we used a quantitative method, but this was rejected after a pilotstudy. Instead we used a qualitatively based method in the sense that weconducted a group interview as well as individual interviews.Based on data from the interviews and our preliminary work a prototype wasbuilt. This prototype is a fluorescent fixture equipped with 2x14W T5fluorescent lamps, dimmed separately.
Mobile Ajax
This report describes a master thesis performed at SICS (Swedish Institute of Computer Science) and KTH (The Royal Institute of Technology) in Stockholm.Ajax stands for "Asynchronous JavaScript and XML" and it's not a programming language, but a suite of technologies used to develop web applications with more interactivity than the traditional web pages.Ajax applications can be adapted for mobile and constrained devices. This has been called Mobile Ajax. While the technique is the same, Mobile Ajax generally is considered to be a special case of Ajax, because it deals with problems specific to the mobile market.The purpose of this thesis has been to examine which possibilities and disadvantages has the Mobile Ajax from developers and users perspective. In addition we compare Mobile Ajax with Java Micro Edition (Java ME) and Flash Lite.This has been done through literature studies and development of a databased chat client (MAIM -Mobile Ajax Instant Messenger). The application sends and receives direct messages in real time between differently mobile devices.
Modeller för utvärdering av set-up för återvinning av lastlister inom IKEA
Reverse logistics is getting more and more attention both from companies and the public. It is an area with the possibility for companies to do good in the eyes of the public. This work focus on the return system of a one-way handling material called the loading ledge. The loading ledge is developed by IKEA as a substitute for the EUR-pallet in transports from suppliers with a long distance and even flow and in transports from suppliers with short distance and uneven flow. The loading ledge is made out of 100 % recyclable plastic.The purpose of this work is to find the most efficient set-up for recycling of loading ledges within IKEA on a European level from a transport and handling point of view considering aspects like cost, environment, time and, from an administrative point of view, user-friendliness.Who will the participants of the set-up be, where will they be located, which transports are needed and which income and costs does the set-up generate, are questions that will be answered.
Emballage för väggelement i trä : Paketering, hantering, lager och transport
As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.
Biogasprocessen : Bestämning av verkningsgrad
Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.
Etiken och rummet : - om det sociala arbetets etik i rumsliga sammanhang
In Sweden there is an integration policy and a policy for national minorities. The integration policy aims to integrate newly arrived immigrants (nyanlända invandrare), whereas the minority policy aims to maintain and strengthen the rights of the national minorities. The national minorities are though, at times, included into the integration policy, even though they hold a minority status in Sweden. This paper aims to, through discourse analysis, investigate the research question: ?how is the content of integration referred to, when it is related to immigrants, contra when it is related to national minorities?.

Tools and Techniques for Project RiskManagement: Perspective of Micro toSmall Scale Construction Firms in Ghana
Detta examensarbete gick ut på att enligt utvecklingsprocessen på Motion Control utveckla en prototyp av en kabelersättare för en produkt på företaget; USB I/O. USB I/O är en mät- och styrenhet och datainsamlingsenhet för USB-porten med flera in- och utkanaler som i flera applikationer har som nackdel att den är kabelbunden. Tanken var att göra en enhet som man ansluter USB I/O till och som kan kommunicera direkt med konventionella ?Bluetooth-dongles? som är vanligt förekommande på konsumentmarknaden.Tre undersökningar gjordes. Den första var en marknadsundersökning för att se lämpliga systemkoncept samt vilka konkurrenter som kan finnas.
Perspektiv på fostran : En begreppsanalytisk studie av fostran i Lgr-11
Syftet med denna uppsats är att göra en begreppsanalys av begreppet fostran för att undersöka vad begreppet innebär, hur begreppet används i den senaste svenska läroplanen, samt undersöka vem som tillskrivs ansvaret för elevens fostran då begreppet förekommer i grundskolans läroplan utan vägledning för tolkningen av begreppet.Begreppsanalysen gjordes i två delar. Den första delen gjordes genom att studera och sammanställa fostrans betydelse i ordböcker, -listor och lexikon, samt hur begreppet används för att belysa vem som tillskrivs ansvaret för elevens fostran. Resultatet av begreppsanalysens första del visar att det är en innehållsmässig, och inte bara grammatisk, skillnad mellan begreppen fostra och fostran, där fostra handlar om att överföra kunskaper medan fostran mer handlar om att påverka beteende.Begreppsanalysens andra del gjordes genom att studera hur begreppet fostran används i läroplanen. Resultatet visar att det i läroplanen talas om två olika sorters fostransarbeten. Det första handlar om specifika värden som skolan ska förmedla och gestalta och det andra fostransarbetet är det elevens föräldrar som har ansvar för, det innefattar bl.a.
Barnens förskola : Ett arbete om barns inflytande utifrån ett normkritiskt perspektiv
Barns inflytande i förskolan är ett aktuellt ämne som dessutom anses vara otroligt komplext, både att förstå begreppet och att arbeta med. Vårt syfte är att synliggöra de normer som kännetecknar en verksamhet där barn får möjlighet till inflytande och vilka konsekvenser det får för verksamheten. Arbetet tar avstamp i kulturanalytisk teori och utifrån ett normkritiskt perspektiv diskuteras sedan resultatet. Vi har utfört en mikroetnografisk studie och data har samlats in med hjälp av semistrukturerade intervjuer och observationer. Empirin har samlats in på två avdelningar på två olika förskolor.
Nya sensorsystem för kombinationseffekter av antibiotika
Idag är antibiotikaresistens ett allvarligt problem. En tillfällig lösning på problemet är att utnyttja synergieffekter som kan uppstå mellan olika typer av antibiotika. Det innebär att antibiotika skulle kunna ha effekt mot bakterier som har utvecklat resistens.I denna rapport har flera olika metoder, för att mäta bakterietillväxt, utvärderats. Dessa metoder indikerar om antibiotikakombinationerna har en effekt. Däribland har både kommersiella och nyligen publicerade metoder undersökts.
Vem ska integreras och hur? En diskursanalys kring hur integration konstrueras då den kopplas till invandrare kontra då den kopplas till nationella minoritetsgrupper

Minkvalpars beteende i större berikade burar vid olika gruppstorlek :
Farmed mink often perform stereotypic behaviours which is considered to be a sign of reduced welfare. Previous studies have shown that enriched cages can reduce the frequency of performed stereotypies. Most studies on mink in Sweden have been done on adults. The aim of this study was to investigate if larger enriched cages with two or four mink kits reduce stereotypies in mink kits during their growth period in comparison to traditional cages.
In the present study the behaviours of mink kits that were kept in four different treatments at a private mink farm were recorded. Traditional cages with two mink kits were used as a reference and the other treatments consisted of larger cages with shelves with two kits, larger cages with shelves and a plastic cylinder with two kits, and larger cages with shelves with four kits.
