AbstractThis bachelor thesis has been assigned by the company ACG Nyström, Borås. ACG Nyström is working in cooperation with a Swiss company named Jentschmann AG. Jentschmann is a manufacturer of ultra sonic welding machines which ACG Nyström is marketing in Scandinavia and the Baltic States. On behalf of Jentschmann AG the company has the aim to introduce the ultra sonic welding technique to new companies.The aim of this thesis is to compare traditional sewing machines with ultra sonic welding machines within two textile areas, protective clothing and outdoor living.Two investigative questions have been formulated for this purpose: what are the differences between a sewing machine and an ultra sonic welding machine? Is it possible to replace the sewing technology with ultra sonic welding? These stand as guidance for this paper.To gather knowledge interviews, literature studies, and tests on two different ultra sonic welding machines were performed.

Rapporten behandlar den designprocess som genomförts under utvecklingsarbetet av en flytväst ämnad för de aktiva sjöräddarna i Svenska sjöräddningssällskapet. Målet med projektet har varit att undersöka sjöräddarnas behov och sedan uppfylla dessa med en ny optimerad flytväst. Den ska innehålla funktioner som förenklar räddningsarbete utan att minska den enskildas säkerhet, den ska ha en identitetsstärkande och för målgruppen tilltalande funktion och design.Projektet syftar till att utveckla befintliga kompetenser inom produktutveckling och komplettera med kunskaper inom sjöräddning och textildesign. Initialt medverkade gruppen i sjöräddningskurser för ökad förståelse och möjlighet att studera fördelar och brister med dagens utrustning. Under arbetet genomfördes intervjuer för att ta del av målgruppens åsikter och önskemål.Omväxlande kreativa metoder tillsammans med kontinuerliga funktionstester hjälpte till att utveckla en väl genomarbetad och fungerande flytväst.

The official statistics on communication and transports in Sweden is administered by Statens Institut för kommunikationsanalys (SIKA). SIKA?s commission includes production of statistics on the Swedish vehicle fleet. These statistics provide important information tofinancial institutes, ministries, industry and mass media among others. Furthermore, the vehicle statistics include measures of comparison between different counties and municipalities.

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

Kransalger är en viktig nyckelart i Östersjön. De förökar sig med hjälp av oosporer och denna studie har syftat till att urskilja morfologisk differentiering mellan oosporer inom och mellan individer och populationer. Främst ställde jag mig frågan huruvida skillnader och likheter i morfologi kan associeras med skillnader mellan olika geografiska avstånd och habitat samt i vilken mån oosporer kan återföras till korrekt population och individ. Kransalger av arten Chara aspera har insamlats på lokaler i östra Svealand och elliptiska Fouriertransformationer har använts för att med hjälp av vågfunktioner beskriva oosporernas konturer. Parametrarna i vågfunktioner har sedan använts för statistiska analyser.

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

Many invasive species propose a big threat against the native fauna in the area that they colonise. Today the raccoon dog (Nyctereutes procyonoides) is speeding from Finland over the border in to northern Sweden. A project to stop the spread and eliminate the individuals that already have established was initiated in the autumn of 2008. To investigate areas that might be interesting for raccoon dogs and to confirm sightings, cameras with auto triggering mechanisms are used. To get the raccoon dog in front of the camera some kind of lure is used. In this study three kinds of different lures was tested against each other?s.

The company Pilotfish has developed the system MIVEO which is used by car-sharing to wirelessly monitor, book or otherwise manage a fleet of cars. In a car pool the system has three different types of users with varying degrees of eligibility. These are end users, administrative and service personnel. We have chosen to focus on opportunities to streamline the administrator and service personnel work with a mobile service, as these users of MIVEO often are movable and mobile. From this position we have in the study attempted to answer the following question: How can mobile services used to streamline administrative tasks? This study is about developing a mobile application that will contain the same features as the existing system, but must be mobile suit.

AbstractThis bachelor thesis was performed at the Royal Institute of Technology in Stockholm on behalf of the Land Survey Authority. The thesis is about fish conservation and division of fishing water at official duty. It is the Land Survey Authority that examines division of fisheries, but before a case can be implemented, certain requirements must be achieved such as FBL 3:8, which prevent divisions that are deleterious for fish conservation. The purpose of this thesis is: to obtain a clearer view how FBL 3:8 should be applied in practice, how the application differs between the offices in central Sweden, and how fish care is regulated at both international and national levels.At an international level, in EU the commercial fishery is regulated through the common fisheries policy (CFP). The fisheries policy consists of a reform that will last for 10 years.

Boberg at Scania CV AB. The purpose was to investigate the technical and customer oriented possibilities for the development of a transport security measure against cargo crime, which is a growing problem in Europe. The main goal was to develop a concept that is possible to implement in the Scania CV AB Fleet Management System. Another goal was to develop a security model that will be used as a tool during Scania CV AB?s future development projects of transport security concepts.The work was divided into three main parts: a background study, handling cargo crime, transport security Scania CV AB trucks and market analysis, a stakeholder investigation including a questionnaire and interviews, and a concept development session.

The ambition of this project is to make an overview of the Swedish upholstery industry and to make a suitable complement to the Carl Malmsten upholstery collection.The Swedish furniture industry employs about 20 000 people in 815 companies. Totally the branch had a turnover of 17,5 billion Swedish krona in the year 2000. Of these 815 companies most of them are small family driven companies with low-tech industry. 10 % of the 815 companies stand for 60% of the production. These are large-scale companies and have a hi-tech industry, even compared with other types of industries.

The Nord Stream natural gas pipeline has been a controversial project. The debate was primarily escalated by Poland's strong negative reaction to the project in the spring of 2006 over safety and security and then alternated back and forth in Europe until the approval by the nations most concerned in the Baltic region during the autumn of 2009.In the case study an approach is used that primarily maps out the media image of the various viewpoints that deal with the pipeline and how these viewpoints position themselves, primarily through political and environmental dimensions. Simultaneously there?s an attempt to map out the spatial spread of the media image views as to the proximity and distance to the pipeline in Sweden, Poland and Germany. A key question is whether distance or proximity to a large facility can affect people's attitudes.A parallel focus of the study is to explore the role of the Nord Stream natural gas pipeline in the cross-border hinterland region of Szczecin-?winouj?cie.

Ovine black coat colour is determined by the MC1R (Melanocortin 1 receptor) and ASIP (Agouti signalling peptide) genes at the Agouti and Extension loci. The black phenotype is caused by production of eumelanin by melanocytes, whereas yellow-tan or light phenotype is the result of phaeomelanin synthesis. The ovine MC1R gene has two known alleles: the wildtype (E+) and the dominant black (ED) alleles. Two missense mutations (c.218T>A and c.361G>A) constitute ED. The presence of a third allele, the e allele, is proposed and believed to give rise to phaeomelanic phenotype.

The Swedish Textile industry has since the beginning of the 70-ties moved their production to countries with cheap labour further and further away. The production in the Baltic countries and Asia has become reality for many Swedish manufacturing companies. With today?s technology the communication with remote countries has ceased to be a problem. The difficulties have instead turned out to be more focused on transportation of goods and just in time deliveries to Sweden.

Förbättring av kvävereduktionsprocessen på avloppsreningsverket Lucerna under WTOS-styrningJonas WenströmÖvergödning av sjöar och hav är idag ett stort miljöproblem vilket samhället bidrar till genom sitt utsläpp av bland annat kväve. Därför har Sverige genom Baltic Sea Action Plan åtagit sig att minska sin belastning på Östersjön från reningsverk med 3000 ton kväve årligen fram till 2021. Om- och utbyggnader av reningsverk kommer att krävas, men en viss förbättring av reningen kan uppnås genom optimering av befintliga processer.Avloppsreningsverket Lucerna i Västervik hade tidigare problem att uppnå tillräcklig kväverening, men sedan processtyrningssystemet WTOS implementerades 2010 klaras kraven. Efter att WTOS implementerats sker luftningen intermittent i verkets aktivslamsteg, i vilken en biologisk rening sker. För att utreda om kvävereningen ytterligare kunde förbättras utfördes denna studie med huvudmålet att lämna förslag på hur kvävereningen kunde förbättras i verkets aktivslamprocess.
