Ny konsumtion av gamla kläder : ? En studie om konsumenters miljömedvetenhet och motiv till att köpa second hand kläder på Myrorna

The world?s consumption is increasing at an accelerating rate and it´s produced and consumed more goods and services than ever before. A large part of people's consumption consists of clothing that is bought and discarded increasingly leading to a number of environmental problems such as global warming, pollution, loss of biodiversity and the depletion of natural assets. One way to save the earth's resources is to buy used clothing, so called second hand, instead of new ones. The store chain ?The Ants? (in Swedish ?Myrorna?) has specializing in second-hand goods and sells, among other things, clothes.

Identifiering av 13 nya mjölksyrabakterier med DHPLC

Mjölksyrabakterier tillhörande släkten Lactobacillus och Bifidobacterium har nyligen upptäckts hos bin och i honungen de producerar och innefattar 13 nya arter[1]. Forskarna arbetar med att ta fram nya snabba och mer pålitliga identifierings metoder för att karakterisera dessa bakterier. I detta projekt undersöktes möjligheten att identifiera dessa bakterier med en ny metod som heter denaturing high performance liquid chromatography (DHPLC). Metoden bygger på separation av PCR (polymerase chain reaction) amplifierade 16S rDNA fragment i DHPLC [8]. Vid identifiering av bakterier amplifierades olika variabla regioner från 16S rRNA genen, som påvisade efter sekvensering störst genetisk variation mellan dessa bakterier [1]. Separationen utfördes med ion-pair reverse-phase high presure liquid chromatoghaphy (IP RP HPLC) med delvis denaturering av DNA molekylen.

Animal welfare in Ethiopia : transport to and handling of cattle at markets in Addis Abeba and Ambo

Stressful routines for animal handling can reduce immune function and productivity of animals. If stakeholders are handling animals aversively, animals will show increased expressions of fear for humans and higher stress levels which lead to the compromise of animals? welfare. In Ethiopia, there are no legislations to protect animals from suffering or discomfort. The main objective of this study was therefore to analyse welfare of cattle on animal markets in Ethiopia and map out supply chains of animals to these markets.

Effekter av högt kaliumintag på magnesiumbalansen hos mjölkkor :

Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms. The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.

Laborationer och vetenskaplighet : Utgångspunkter och validitet vid bedömning av laborationsrapporter

Livsformerna på jorden delas systematiskt in i de tre domänerna bakterier, arkéer och eukaryoter. Arkéer är de mikroorganismer som lever i extrema miljöer såsom hetvattenkällor, sjöar med hög salthalt och i miljöer med extrema pH-värden. De kan existera i miljöer där inga andra organismer överlever men förekommer även rikligt överallt runtomkring oss, exempelvis i människans mage och som normalflora i munnen.Vissa bakterier och arkéer har genen för enzymet ammoniak monooxygenas (AMO). Detta enzym spelar en viktig roll vid rening av avloppsvatten genom att oxidera ammonium till nitrit.Syftet med detta examensarbete har varit att detektera arkéer i prover av aktivt slam vilket gjordes genom att optimera en Polymerase Chain Reaction (PCR) baserad metod. Först pelleterades slamproverna via centrifugering för att kunna preparera DNA.

Supply Chain for Local Vendors : En fallstudie av en ny lösning för att hantera inköp

Att hantera kunskapen inom organisationer blir allt viktigare för att kunna förbättra den organisatoriska konkurrenskraften. Detta kan bland annat uppnås genom ett ökat utnyttjande av kunskapskapitalet. Kunskapskapitalet brukar vanligtvis handla om att utforska tacit kunskap, det vill säga den kunskapen som finns i de anställdas sinnen.Från år 2010 och fyra år framåt förväntas en stor utmarsch av 40-talister från den svenska arbetsmarknaden. Detta kommer att få konsekvenser på arbetsplatserna. Konsekvenserna kommer bland annat att bli i form av underskott i kunskapskapitalet.Syftet med uppsatsen är ta fram en modell som illustrerar hur kunskap kan identifieras och överföras.

Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?

Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

Logistik

The construction industry develops at a high pace today. Because of this the construction companies has to rethink and try to develop at the same pace. One of the biggest challenges in the construction industry today is to improve the logistics since improved logistics leads to lower costs. This is something that the construction companies have started to realize and they are beginning to invest more money in order to improve the logistics. It is especially important to have good logistics when the conjuncture turns for the worse.

PR i det dolda : en studie om Redaktionell PR

The fashion industry is a line of business which is characterised by tough competition. Often the consumer target groups exposed to advertisements identify them as attempts by the fashion industry to persuade them. When this happens, the consumer disregards the information due to selective attention. Faced with these conditions, companies need to find new, creative ways to market their product lines. This essay is about Public Relations, in particular Public Relations that appear in editorial spaces.

The problems around and the planning of wood flow is some of the most complex issues in the forest-sector. The experience and overview of the single employees is crucial for the possibility of correct tactical and economical decision-making. The increasing demand of savings and shorter reaction-times with greater flexibility in the wood-supply-chain, makes solutions and aids for improved effectiveness in the work and processes according to wood-flow urgent. Holmen Skog is starting to develop a new forest-road-management-system. The system will facilitate the work according to construction, improvements and updating the standard of roads.

Improvement of positive strand assay used in detecting positive and negative RNA of hepatitis E virus

Background: Hepatitis E (HEV) is a small, non-enveloped virus that belongs to the viral genus Hepevirus. HEV is a positive sense single-stranded RNA virus and there is insufficient information regarding its replication. This is mainly because the virus has low capacity to grow in normally used cell cultures. Many specific strand assay detection studies have been done in order to understand more about HEV replication. Unfortunately, these assays have the disadvantage of giving false positive results.Aim: The aim of this project was to improve the positive strand assay to increase specificity and eliminate false positivity which is due to high sensitivity of the polymerase chain reaction (PCR).

Produktivitet i robotcell

The report describes the process of identifying the interference that exists in a newly installed automated robotic cell and suggest improvements to increase productivity. The cell is used for lifting up extruded aluminum sections onto a conveyor which deliver the material to a anodising line at a company that manufactures aluminum extrusions.To find the areas with the best possibility for improvements in the cell we used a variety of job measurements e.g. measure of standard times for each operation in the cell. The core of the report is a study of the robots.One reason for this study is that the robots do not reach the productivity they were purchased to. The main cause not reaching the productivity is the visionsystem.

Rätt klädd? : En studie om klädföretags arbete och kommunikation av CSR

The number of firms adapting the concept of Corporate Social Responsibility is constantly growing. It is no longer enough only to supply your customers with demanded products and services since todays? customers have an increased awareness and are demanding more transparence when it comes to the manufacturing and responsibility for society.Along with a growing interest in social, ethical and environmental matters, many firms have received critique, consequently forcing them to start taking more responsibility for their activities. The clothing industry was among the first to get critized and therefore early in starting their work with CSR.The purpose of this paper is to investigate how firms in the clothing industry work with CSR today, and also how they choose to communicate this work, both internally and externally. The methodology of the paper is qualitative and aims to deeply investigate four different firms, along with an additional interview with a CSR-consult from one of the leading communication-firms in Sweden.The theoretical foundation includes a frame of reference around CSR and the communication thereof, and also a few relevant theories around CSR and business ethics.After analyzing the empirical material the paper have reached a few conclusions.

Att upprätta ett konsignationslager ? en best practice

I en mer global och konkurrensutsatt marknad krävs, i allt större utsträckning, att företag väljer att differentiera sig med specifika kundlösningar istället för den enskilda produkten. Genom att, tillsammans med kunden, skapa värde knyter man denna närmare till sig. Ett konsignationslager är en strategisk lagerlösning för att minska avstånden mellan kund och leverantör samt att minska kedjans totala lagerkostnad. SCA Timber har begränsad erfarenhet kring konsignationslager. Av den anledningen har det funnits oklarheter kring hur arbetet bör organiseras. Syftet med studien är att ta fram en best practice för hur SCA Timber ska arbeta med upprättandet av framtida konsignationslager. Studien är en multipel fallstudie av fyra verksamheter inom SCA och baseras på kvalitativa, semistrukturerade intervjuer med respondenter som varit inblandade i upprättandet av konsignationslager. Det empiriska materialet består av fjorton intervjuer. Studien utgår ifrån ett teoretiskt ramverk bestående av teorier kring projekt, kritiska framgångsfaktorer i projekt och skapandet av nyttjandevärde.

Ansvarsfull produktion ? vägen till kundens hjärta?

Responsible production is a subject of increasing importance for companies toadopt and communicate to their environment and many companies choose to implementenvironmental ? and ethic considerations into their brand strategy. There is, however, adividing line between companies according to what extent they choose to implementresponsible production into their brand strategy and to which extent they choose tocommunicate it to their stakeholders and surroundings. It is the hypothesis about a dividingline that is the foundation for this essay and something we believed could be interesting forfurther analysis.The purpose of our essay is to find out how the brand strategy of a company is affected by theresponsible production and in what extent they communicate it to their environment. Byanswering those questions we hope to find out why some companies communicateresponsible production more actively than others.We have conducted in-depth interviews with the Swedish clothing companies; MariaWesterlind, Zion and Dem Collective and we have through our analysis reached interestingconclusions.
