When several production units provide a district heating network, water is pumped from different directions. When the flows from the plants finally meet in the network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may cause wear on the pipes, a phenomenon called low cycle fatigue.For this reason it is important to examine where and when zero flow zones that cause temperature changes occur.

Dåliga arbetsförhållanden, bristande säkerhet och omänskliga situationer är rubriker som cirkulerar allt oftare i media. Globaliseringen har lett till att företag i allt större utsträckning sourcar sin produktion till aktörer i utvecklingsländer där arbetsförhållanden enligt västerländsk standard är oacceptabla. Skandaler inom mänskliga rättigheter och miljöutsläpp är skadliga för företagens rykte. Detta är något de aktivt måste jobba med för att motverka och i detta avseende är kinesiska textilfabriker en stor riskgrupp. Syftet med rapporten är att utreda hur företag kan arbeta för att skydda sig mot ordrägliga arbetsförhållandne i sina fabriker samt hur de kan förbättra arbetsförhållanden i dessa.

In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the Supply Chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.

Title: Food companies' work with CSR and its impact on consumer purchases of organic productsLevel: Final assignment for Bachelor Degree in Business AdministrationAuthor: Maria Nilsson and Mikaela JaredalSupervisor: Agneta SundströmDate: June 2015Aim: The study aims to understand and describe how food chains affect consumer choice to buy organic food and how it affects their buying behaviour.Method: Firstly a qualitative study was conducted. It consisted of six semi-structured interviews with store managers and employees on Willys and Coop in Sala and in Nyköping. Secondly a quantitative study was performed in the form of a questionnaire with 80 consumers in Willys and Coop stores located in Sala and Nyköping.Result & Conclusions: We have seen that price is important when consumers decide whether to buy organic food or not. This has been noticed by the food chains who work actively with being able to offer organic food at lower prices. Other factors that affect the consumers choice to buy organic products are offers, displaying and advertising.

Bakgrund och problemformulering:I takt med ökad globalisering och en större press på att minska kostnader så blir företagens inköpsfunktion en allt mer viktig konkurrensfaktor. När inköp går från att vara en administrativ funktion till att få en alltmer strategisk roll så ökar betydelsen av att värdera hur denna funktion bidrar till företagets resultat och konkurrensförmåga. Eftersom andelen inköpta varor och tjänster ofta utgör en betydande andel av företagets kostnader så kan inköpsfunktionen få en avgörande strategisk roll. Vår studie tar avstamp i denna debatten och avser att studera och analysera fyra bolags inköpsprocesser för att se hur dessa är unika och skapar konkurrensfördelar.Syfte:Syftet med studien är att beskriva och analysera olika möjligheter att skapa konkurrensfördelar genom inköpsstrategiska val.Metod:För att besvara vårt syfte valde vi att intervjua och studera fyra företag i olika branscher för att få en bred bild av inköpsprocessen och hur den integreras i företagets värdekedja. Uppsatsens angreppssätt kan betraktas som abduktivt då vi har pendlat mellan teori och empiri för att nå till vår slutsats.Teori:Vi har studerat ett antal olika böcker och artiklar som behandlar inköpsprocessen, vilka metoder det finns för att värdera och mäta denna samt inköpsfunktionen ur ett strategiskt perspektiv.

The main drivers of luxury consumption is to obtain prestige and status, therefore the possibility of visible consumption of products is a key dimension of the product. Typical examples of luxury goods include cars, handbags and watches. These are consumed in the public arena where the possibility to show off the product and the brand is the greatest. When examining luxury products and what drives men and women to pay premium prices for a brand and for a logo, a fascinating finding is that there are products that fundamentally lacks these attributes, but which are considered to be classic luxury products. An example of this is perfume.

In the profession of architects there is an element called architectural competitions, where several architects compete in submitting the best solution for a certain task. In this master?s thesis I am studying the competitor?s perspective of an international architectural competition, while at the same time gaining experiences for my future career as a landscape architect. The aim of this thesis is to through an introspection of my own process examine a competitors view of the international architectural competition and how to approach the difficulties concerning international competitions. Through that I hope obtain experience about the international competition as part of the profession of landscape architects and other involved professions. To examine a competitor?s reflection of an international competition, I entered and competed in LE:NOTRE Student Competition, a competition for students where the task was to develop 25 kilometers of complex urban periphery along a chain of natural and artificial lakes in Bucharest, Romania.

This degree project was conducted in collaboration with Husqvarna AB, the headquartersof which are located in Jönköping. The aim was to further develop the filler cap found onmore or less the whole of the company?s range of chain saws, in order to make it moreuser friendly.The present filler cap is not easy to open and close, especially when wearing gloves, andunder difficult conditions, which creates problems and prolongs filling time.On the basis of market surveys, different prototypes and tests, we have created anergonomically improved cap of a new shape, which can be moved in the axial direction,thus making filling easier..

Divisionen Underground Rock Excavation på Atlas Copco tillverkar kundanpassade gruvmaskiner i världsklass till kunder i mer än 170 länder. Från inköpsperspektivet är majoriteten av leverantörerna svenska men de dyraste komponenterna köps in från utlandet. Detta gör att stora krav ställs på både logistiken och produktionssystemet. De senaste årens ökande efterfrågan har lett till att materialförsörjningen har svårt att hantera de volymer som krävs och till följd uppstår störningar. En effektivisering och kapacitetsökning är nödvändig och därför kommer detta examensarbete att handla om kartläggning av material- och informationsflöde samt bristidentifiering av störningar i materialflödet.

Background: Insufficient nutritional support is associated with prolonged hospitalisation, impaired wound healing and impaired survival for patients in intensive care. In severe sepsis and septic chock, calculation of nutritional need is complicated since the metabolism is affected by decease. Aim: The aim of the study was to investigate nutritional support and to examine the quality of nursing documentation of nutritional status and nutritional support in patient records in severe sepsis and septic chock.  Method: The study was conducted as a retrospective investigation where 64 patient records were studied. The quality of documentation was examined in 10 patient records using an examinational model.Findings: Calculation of average nutritional support showed insufficient supply particularly in the two first days of intensive care. During the next five days nutritional supply was higher but individual variation was seen, why a clear picture of nutritional support is hard to detect.

To regularly remove woody vegetation along the roadside of forest roads is an important part of the road maintenance, since the vegetation binds moisture in the road side and, thus, the removal makes the road drying faster with results in improved bearing capacity. Vegetation removal also makes it easier to upgrade the road by material recycling from the ditch and, moreover, the visibility along the road is maintained.The aim of the study was to evaluate what type of chain flail is the best and most cost-effective for removal of different kind of woody vegetation along forest roadsides.Time studies were made on two chain flails when removing woody vegetation in three different classes; easy-, middle- and heavy shrub removal. The studied flails were one light and rather simple flail named Optimal M160 and a heavier and more advanced flail named Slagkraft H210. The removal was made according to Holmen Skogs? specification and the quality of the cleaning was measured by objective belt inventory.The productivity was higher with the heavy flail within all cleaning classes.
