Stadskyrkogårdar : socialt hållbar stadsutveckling

This master thesis is a study of how city cemeteries can be used and contributes to a socially sustainable urban development. Today sustainable development and sustainable urban development is something that more or less every organization is working with. Therefore it is also relevant to integrate our cemeteries in this work so that they can become a part of the sustainable urban development process.The thesis gives a basic understanding of sustainability as a concept and also defines socially sustainable (urban) development. The work then immerse itself in various types of park structures and how the relationship between the human individual and the public space work, to satisfy the needs that different people have.The literature study that has been made is also the base for the design of the walking interview that has been made for the two city cemeteries. The cemeteries that where studied where the Assistens cemetery in Copenhagen and the Eastern cemetery in Gothenburg.

Grön logistik vid globala logistikföretag : En undersökning av godstransporters hållbarhet

På senare år med den fortsatta globaliseringen har miljöfrågor blivit allt viktigare. Eftersom transportsektorn står för en stor del av den totala miljöpåverkan är det viktigt att logistikföretagen tar ett miljömässigt ansvar och arbetar med så kallad grön logistik. På grund avde ökade avstånden vid global handel och ökade bränslepriser är det viktigt med miljövänliga alternativ. Syftet med denna studie är att undersöka hur de globala logistikföretagen bedriver sitt miljöarbete, främst kring transporterna. Detta sker genom en studie av vetenskapliga artiklar och intervjuer med miljöansvariga hos Schenker, DHL och Green Cargo.

Vägval: kortast, snabbasteller hälsosammast : En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter

Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.

Utveckling av takra?cken fo?r sla?pvagnar

This report is a bachelor thesis work in the field of product development and design. The assignment has been to develop a solution for roof racks, normally used for cars, to fit on the open trailer models FS1425 and Alugance. The project was implemented by Johan Andersson and Victor Karlsson, students at the Mechanical Engineering program with a focus on product development and design at Jo?nko?ping?s school of Engineering, in spring 2012.The client wants to use transport solutions in the same way as roof racks on cars. The user of such a product is assumed to desire simplicity, safety and an attractive design with an appealing price, which has been a challenge during the thesis work.Pre-studies have been conducted to examine the potential competitors and gain knowledge in the research area.

Trygghet kring hållplatser. Ett framtaget verktyg vid trygghetsanalysering i samband med hållplatser och dess närmaste omgivning

Att människor idag avstår från att delta i sociala aktiviteter i samhället på grund av att de känner sig otrygga i kollektivtrafiken, och då särskilt på hållplatser och vägarna till och från, går inte ihop med Göteborgsregionens mål om en ökad användning av kollektivtrafiken. För att få fler att välja kollektivtrafiken som färdmedel måste tryggheten kring hållplatserna öka, vilket skulle innebära fördelar för både hälsa, miljö och välfärd. Det är speciellt kvinnor som anger att de, särskilt kvällstid, avstår från vissa aktiviteter för att de inte känner sig trygga på hållplatsen eller väljer att gå långa omvägar hem för att de känner sig otrygga. Olika fysiska åtgärder, i det offentliga rummet, påverkar den upplevda tryggheten hos människor och med enkla medel tryggheten öka avsevärt på en plats.Syftet med detta arbete är att belysa trygghetsfrågor i samband med hållplatser i Göteborg för att bidra till den debatt som finns angående trygghet i kollektivtrafiken.För att göra detta har en analysmetod tagits fram och ett verktyg har utformats för att undersöka tryggheten på en hållplats och dess närmaste omgivning. Detta kommer att underlätta prioriteringar och utveckling av platsen ur en trygghetssynpunkt.En omfattande litteraturstudie har genomförts för att få en uppfattning av begreppet trygghet och vad det innebär.

Perspektiv på avreglering av svensk järnvägspersontrafik

This thesis examines the deregulation reform of the Swedish railroad industry, focusing on passenger transport between 1988 and 2005. The purpose of the thesis is to examine the effects from the deregulation reform on prices, market concentration and to determine whether SJ (the state owned incumbent) has been conducting strategic behaviour in order to prevent new entrants to the market. The chosen method consists of interviews with the MD at SJ between 1988 - 1998 Mr Karl-Erik Strand, the transportation researcher at SSE Mr Gunnar Alexandersson. Statistical sources and companies financial reports have also been used. The results that I have found were besides the fact that the market concentration is still significant high and the profitability among the operators low, is that the prices has increased more than CPI during the period but the competitive tendering has resulted in lower government subsidies after the deregulation.

Shooting Target - Design : Product Development

The project has involved the development of two kinds of shooting targets in partnership with Marcus Bergkvist and Christopher Åkerblom. The project from the client was divided into two parts. This thesis discusses solutions for hands-on transport, development of tripods and an overall design. The second thesis affect resetting systems for the products.The work was done with a process and methodology based on design perspectives. This process has involved the search of relevant data which has provided the platform and opportunity for appropriate and purposeful design work.Concept development has been done using hand sketches and Photoshop, where a simple visualization of different concepts for the tripods has been produced.

Controlled traffic for grass silage production : an economic evaluation for dairy farmers

The farm management system controlled traffic farming (CTF) aims to reduce soil compaction by restricting the field traffic from agricultural machinery to permanent traffic lanes. Literature and empirical findings show that soil compaction and field traffic from heavy machinery may affect crop growth negatively, reducing crop yields. If grass-clover leys are subject to heavy field traffic the botanic composition might be altered, providing a lower clover content in the forage. Clover as a silage feed is rich in protein providing good conditions for high yielding dairy cows. Grass-clover silage production is generally associated with intensive field traffic.

Effekten av uteblivna miljöersättningar för anläggning av våtmarker

Environmental subsidies are used as incitements to farmers for development of sustainable land use. In 2014, applications for funding constructed wetlands were not available. This paper examines the environmental consequences of this lack of funding in one intensively cultivated region Skåne län, southern Sweden.A review of wetland applications between year 2007-2013 show that the average rate of applications has been 31 projects per year with a wetland size of 4,48 ± 1,61ha per project (mean±95% CI). Based on interviews, the result suggests that the lack of funding in one year leads to between 102 and 140 ha of constructed wetlands that is not built. This correspond to a total loss of increased nitrogen retention capacity between 6,0 and 91,7 tons/year and a loss of increased phosphorus retention capacity between 0,17and 2,1 tons/year in the drainage basins of Skåne.Further the interviews show that continuity of environmental regulations and funding is important for the farmers? interest in environmental measures.It is concluded that the total loss of increased retention capacity is small compared to the annual transport of nitrogen and phosphorus in the drainage basins.

They deliver door frames for indoor use for project oriented buildingsites, for these types of building sites the doorpost comes pre-assembled. DooriaAB wants to minimize transport to reduce impact on environment and thetransportation costs of pre-assembled doorframes, this thru simplifying themethod of assembly.The main purpose of this thesis has been to develop a prototype solution thatbrings the three parts of the doorframe together with the same properties regardingstability and tightness of joints as the current method of assembly. A profile ofdemands and wishes were created in collaboration with Mårten Dragstedt, DeputyDirector of Dooria Sverige ABBy following the chosen method the authors have been able to produce a fullyfunctional prototype that meet the demands that were put on the product. Catia V5R20 has been used as an aid during prototype construction and virtual tests.

Mögel på Textil -vid import av textila varor

Under lagring och transport av textila varor från Asien kan risken för mögelangrepp vara stor, något som sedan vid uppackning kan vara skadligt för hälsan. Situationen så som det ser ut idag kan medföra stora problem och kostnader hos textilföretag och att hitta möjliga åtgärder för att förebygga skador är därför av stort intresse. För att kartlägga problemen med mögelangrepp på textila material har både informationssökning och praktiskt arbete genomförts. Mögeltillväxt sker då det är gynnsamma betingelser med hänsyn till klimat, näring och syretillgång. För att mögeltillväxt inte ska angripa textila varor finns en rad förebyggande åtgärder som kan vidtas, åtgärder som alla handlar om att göra förutsättningarna på ett eller annat sätt ogynnsamma.
