Tilläggsisolering - lönsamt enligt en livscykelkostnadsmodell?
It is found that the properties of the record years of 1965-1975 is leaking a lot of energy andthese properties are facing a major energy efficiency. From the energy aspect, the facade isafflicted with poor thermal insulation which is a big problem. To address this problem addinginsulation is a good alternative to reduce overall energy consumption of a building. Thewindows on these buildings are also a problem from the energy point of view. Therefore,there are many reasons considered for energy upgrading.
Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
EFFEKTIVISERING AV DELMOMENT I PROCESSKARTLÄGGNING
Den här C-uppsatsen har gått ut på att göra en processkartläggning på återuppbyggnaden av Vivallaskolans bollhall som har brunnit ner under slutet av oktober 2010. Utifrån processkartläggningen har det gjorts analyser och observationer på aktivitetsflödet. Där framgår det vad som har gått bra och mindre bra. Till det som har gått mindre bra har förslag till lösningar tagits fram. I dessa lösningar ingår metoderna: PDCA (s.21), BIM (s.21) och Ishikawadiagram (s.21), som tydligt visar förbättringsåtgärder.Processkartläggningen och lösningsförslagen har tagits fram utifrån observationer i form av besök på arbetsplatsen samt läsning av litteratur och elektroniska källor.
UN Guiding Principles on Business and Human Rights utveckling som norm: En analys av Sveriges regering, Volvo och G?teborgs Stad
Since the 1990s, when the number of transnational companies increased, it has created challenges regarding the responsibility of human rights. As a response to these challenges the United Nations Human Rights Council (UNHRC) unanimously endorsed the new policy UN Guiding Principles on Business and Human Rights (UNGP) in 2011. UNGP does not have the status av international law, yet simply as guidelines and its implementation is based on good will and voluntary efforts. Now, 10 years later, this study aims to get understanding regarding if UNGP is considered as norm by the Swedish Government, Volvo and Gothenburg Municipality. The material of the study consists of sustainability reports, annual reports and governmental documents with focus on human rights in relation to business published between the year of 2011, when UNGP was endorsed, until 2020.
Att planera för ett hållbart transportmedel : en studie av dokumentet Cycle Policy 2002-2012 som en del av planeringsprocessen bakom Köpenhamns cykelvägnät
Köpenhamns cykelvägnät har anor så långt som 100 år tillbaka i tiden och på 1980-talet genomförde stadens cyklister stora demonstrationer för att få politikers och planerares uppmärksamhet, som man ansåg hade förlorat fokus på cykeln i planeringen (Jensen, muntligen, 2011-05-02). I detta arbete presenteras siffror som visar att det idag är fler än en tredjedel av Köpenhamns invånare som cyklar till och från sitt dagliga arbete. Köpenhamns kommun vill öka det antalet och målet idag är att bli världens bästa cykelstad år 2015 (Köpenhamns kommun 2007). För snart tio år sedan upprättade man på Köpenhamns kommun ett dokument, Cycle Policy 2002-2012, innehållandes mål för att förbättra förhållanden för stadens cyklister till år 2012. Detta dokument har studerats närmre i denna uppsats.Som blivande landskapsarkitekt blir jag nyfiken på hur de gått till väga.
Synchronizing migration with birth: an exploration of migratory tactics in female moose
Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.
Ett tält för sju dagar : Festivaltält i papper
SummaryAt the summer festivals and it?s campsites there are each year thousands of tents left behind. Last year, at the Peace and Love festival in Borlänge, 220 tons of garbage was left behind at the festival area, much of which is tents. 69% of festival goers have at some point left behind a tent on a festival campsite. Many of these tents is purchased very cheaply, for a single festival.
De traditionella filmuthyrningsbutikernas skapande av lojala kunder på en mättad marknad
This essay is about the market of traditional rental movie stores, which today are on a mature stage of the marketing cycle. The technique is constantly accelerating and contributes to evaluation of new ways to watch movie. New competitors are such as bigger chain of stores that can offer, in addition to their wide range of other goods, rental movies as a secondary selling. The substitute is of most part Internet based services from where you can watch movie online or download film legally as well as illegally.These different sorts of new competitors or substitutes become a big threat on the traditional rental movie stores as these substitutes can offer the same prices or even lower.With these new ways of watching film this will on turn change the behaviours of the customers that likes to watch movies. The problem for the traditional rental movie stores is trying to keep their existing customers and try keeping them loyal to their store, so that they won?t loose them to the competitors and substitutes.

The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.
Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements
The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive.
The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of
association analyses.
Brunstvisningsförmåga hos mjölkkor- en beteendenstudie
Oestrus in dairy cattle has changed over the last decades; the intensity of oestrus has declined and the duration decreased. Several studies have shown that not all dairy cows stand to be mounted, and that oestrus expression in many cases may be characterized by other behaviours. The aim of this study was to investigate oestrus behaviour in a herd of todays? high producing dairy cattle. The study was carried out at Jälla naturbruksgymnasium in Uppsala during one week in January 2011.
Verktyg för värdering av miljöpåverkan vid investeringar i det svenska elstamnätet
During the period 2009-2013, investments in the Swedish national grid increase by a factor of ten compared to previous years. In order to fulfil their mission to manage the national grid in a safe, efficient and environmentally sound way, Svenska Kraftnät (Swedish National Grid) needs to take all these perspectives into account while planning new investments. To compare and relate perspectives of technology, economy and environment the same yard stick must be used. That yard stick is commonly money. A problem arises however as environmental issues are difficult to price.The purpose of this master?s degree project was to develop a tool for evaluation of environmental impact related to investments in the Swedish national grid.
Reducering av ställtider
För att vara konkurrenskraftig i dagens globaliserade företagsklimat krävs kostnadseffektiva lösningar som gör det möjligt för företag att möta kundernas krav gällande såväl kvalitet som pris och förmåga att leverera enligt överrenskommelse. Gevalia, ett producerande företag i Gävle, har problem med långa ställtider som markant drar ner deras effektivitet. En universell vedertagen metod för att minska ställtider är SMED, Single minute exchange of die, som anses kunna göras kompatibel i alla typer av industrier. Syftet med detta examensarbete var således att undersöka orsakerna bakom de långa ställtiderna samt hur dessa kan minskas. Vidare skulle en analysstruktur för ställtidsreduktion skapas. För att uppnå syftet har intervjuer och observationer gjorts på Gevalia, samt en litteraturstudie kring berörda områden. Analysstrukturen som skapades är inspirerad av SMED och PDCA-cykeln. Strukturen innefattar även andra metoder som bland annat 5 Why och 5S, samt tar hänsyn till det mänskliga beteendet.
