Vinster med återvinning, Stena Recycling

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

ANALYS AV FLERBOSTADSHUS : Med inriktning på ytfördelningen över tiden

Currently, there are no clear statistics on how the floor plan and room size in apartment buildings has changed over time since the postwar period. The statistics available is average area per apartment which can be found on Statistics Sweden's website. This report has the aim to increase knowledge about how the Swedish home have changed over time.The questions that the report will answer are:For apartment buildings, how has the living area been distributed since the postwar period?Why has the area distribution changed over time?A survey of the houses built during 1950-2014 was made before questions could be answered. A case study was also made which a total of 90 apartments were analyzed and divided into three eras, the people´s home, the million programme and the neomodernism.

Barn gör inte som du säger, de gör som du gör

Sammanfattning och förord Studien fokuserar på lärarstudenters syn på fritidspedagogens roll för fostran av barn på fritidshem. Den franske sociologen Bourdieu och hans tankar om socialisation är studiens huvudsakliga teoretiska perspektiv. Bourdieu talar om fält, kapital, praktiskt sinne och habitus. I min studie jämför jag Bourdiues tankar med några pedagoger såsom Dewey och Säljö vilkas arbete är mer sociokulturell inriktat. För att tydliggöra hur fostran av barn på fritidshem sker har jag intervjuat tio blivande lärarstudenter vilka studerar med inriktning mot fritidshemmets pedagogik.

Analys av åldersstrukturen hos sik (Coregonus lavaretus) i sjöar utan gädda (Esox lucius)

Development of morphs within European whitefish (Coregonus lavaretus), might be considered as a beginning of a sympatric speciation process. Unpublished data suggests that presence of the keystone piscivore northern pike (Esox lucius) is the main driver of sympatric divergence in European whitefish (Coregonus lavaretus). Using introduced whitefish populations as controlled experiments, it is possible to determine when different characters diverge in the speciation process. In this study, I analysed age and growth within European whitefish populations of different age to assess if these characters change over time in absence of pike. With using otoliths from whitefish populations of different age, I was possible to determine individual age, and by measuring the length of the fish, growth was calculated.

Resurseffektiv livsmedelsproduktion : Tillämpning av industriell symbios för ökad resurseffektivitet inom den svenska tomatodlingsbranschen

Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.

"Man är liksom mittemellan". En kvalitativ studie om 10-åringars perspektiv på sin livssituation

The purpose of this essay was to, by the ecology of human development theory, examine 10-year old childrens own experience of their lifesituation outside the time of school. The study was based on qualitative interviews with six 10-year old children from a smaller community in Sweden. The main guestions was:1. What is the experience of being 10 year?2.

Variabilitet i voice onset time : En studie av svenska femåringars initiala klusilproduktioner

Voice onset time (VOT) är en akustisk tidsparameter som återspeglar den talmotoriska samordningen. VOT betraktas även vara det mest tillförlitliga sättet att särskilja mellan tonande och tonlösa klusiler.VOT hos barn har tidigare studerats i logopediuppsatser vid Linköpings universitet (Lundeborg et al., 2012; Larsson & Wiman, 2011). I dessa arbeten har dock inga upprepade mätningar gjorts, varför det föreligger behov att fastställa hur konsistent barns VOT är. Denna studie syftar till att undersöka hur konsistent klusilproduktionen är hos svenska barn i femårsåldern, samt utreda förekomsten av eventuella könskillnader.I studien medverkade 31 barn, 13 flickor och 18 pojkar där medelåldern var 5:6 år. Barnen fick benämna bilder av minimala par med klusilord tre gånger.

En invändning mot McTaggarts argument för tidens overklighet

Inom den teoretiska filosofin så finns det ett antal klassiska texter och argument som de flesta förr eller senare kommer i kontakt med. En av dessa texter är den uppsats medtiteln Time som John McTaggart Ellis McTaggart fick publicerad 1908. Uppsatsen är ett försök att övertyga läsaren om tidens beskaffenhet, för att senare konstatera att det ärsjälvmotsägande att påstå att någonting skulle ha egenskapen att finnas i tiden. McTaggarts egen slutsats, att tiden inte existerar, är en ståndpunkt som är som gjord för att skapa debatt och debatt kring texten har det blivit..

Kartläggning av kapacitetsutnyttjandet och ställtider på Stålöv AB : Survey of the use of capacity and set up times at Stålöv AB

The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.

Optimering och validering av PCR-metod för diagnostik av svampinfektioner i nagel

Nuvarande metoder för att diagnostisera svampinfektioner i nagel är långsamma och troligen ganska okänsliga. Diagnostik görs vanligen genom direktmikroskopi och odling på svampsubstrat. I ett försök att minska analystiden och att öka känsligheten användes i denna studie realtids-PCR (Polymerase Chain Reaction) för att påvisa dermatofyter. Optimering och validering gjordes av en PCR som var generell för dermatofyter och en PCR som var specifik för Trichophyton rubrum. Optimeringen innefattade annealingtemperatur, Mg2+-koncentration och primerkoncentration.

Methods for Locating Distinct Features in Fingerprint Images

With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.

Wilde ? Mannen som föll offer för den hegemoniska maskuliniteten : En begreppshistorisk analys av fem författares framställning av Wildes homosexualitet 

The aim of this study has been to examine six books about Oscar Wilde?s homosexuality during the years 1906 ? 2003. I have been analyzing their descriptions about his sexual orientation and compared them to each other to see the changes through time. In order to see some clear changes the main focus was to choose time differences between the books. It was clear that the earlier writers had negative opinions and thoughts about his sexual deviation the way they described it.

Äldres erfarenheter av aktiviteter i ett socialt sammanhang. En narrativ studie om den åldrande människan

There is no general aging process therefore should health efforts directed at elderly population based on each individual as a unique person with specific needs. When aging becomes a fact not generally decrease the lust and the desire to be active but it is perhaps more about the body's ability to keep up on what the head wants. Therefore the range of activities towards the elderly population requires some adjustment that can partly be achieved by taking some of the older people?s experiences. The purpose of this study was that by the older people?s experiences of organized activities in a social context to illustrate how they perceive their participation.

Uppfyller BIM förväntningarna som arbetsmetod för broprojekt?

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.
