Our Bachelor´s Thesis has been performed in co-operation with Bors Automation & Tool AB.Our task was to develop a servomotor powered tube cutting-machine with initial point fromtoday's hydraulic driven tube cutting machine Bors HYD 23. The purpose with the newconstruction was to achieve a more power-efficient tube cutting machine which could lowerthe power consumption, and also meet the market continued growing demand forenvironmental-conscious production.Bors Automation & Tool gave us relatively free hands in order to enable new thinking ideaswithout following their traditional constructional solutions.Our solution resulted in a construction based on a power source existing of a servomotordrivenrollerscrew, witch provides a more rational use of energy compared with the currentmethod.Bors Automation & Tool AB has decided to fabricate a prototype of Bors E 23 during theautumn of 2007, which they are planning to revile at the Tube 2008 exhibition in Düsseldorf,Germany.NOTE:Due to an agreement signed by the authors in the beginning of this project, no appendix is published at this time.If you want to wiew these documents, please contact the authors..

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.

The Swedish prehospital/ambulance organization has the last decades evolved from a transport organization to a an organization that focus on alleviate and treating acute medical conditions in the field as well as transporting patient to the emergency ward. The ambulance service is developing continually and offers today a high-tech and highly specialized nursing/care. Which in turn demand a higher standard and competence on the care provider. Ambulance mission can vary in priority and magnitude. This in turn demand a high medical competence our capacity.

Commissioned for this report is Ramboll, Bridge and Tunnel Unit in Stockholm. Theidea throughout the work has been to primarily help bridge designers compilingadvice and instructions on how fatigue verification for railway bridges in reinforcedconcrete shall be performed under the new rules, the Eurocodes.After the introduction of the Eurocodes in 2011 has major problems emerged amongdesigners around Sweden. In some areas, it differs in the calculation rules comparedwith rules from the Swedish Transport Administration and the National Board ofHousing, Building and Planning calculation. Fatigue verification is one area where thenew calculation rules are different from the past.A large part of the report has been to interpret and find the relevant information inthe Eurocodes concerning fatigue. When questions or doubts have surfaced, this hasbeen discussed with Elisabeth Helsing at the Swedish Transport Administration andbridge designers at Ramboll.The result is a report where the structure is organized in the way that the bridgedesigners can move from cover to cover and realize that fatigue verification in realityfollows the same order as the report's sections.

Jag har i detta examensarbete analyserat behovet av väg- och trafikinformation i samband med skogstransporter och jämfört behovet med den information som Vägverket tillhandahåller. Arbetet har utförts på uppdrag av Vägverkets ITS-sektion, den avdelning som ansvarar för Vägverkets uppdrag att öka användningen av IT i trafiken. Målet med arbetet har varit att undersöka hur väg- och trafikinformation kan bidra till bättre skogstransporter och bättre trafik. Syftet har varit att ta reda på hur en perspektivväxling mellan trafik och transport påverkar tjänsteutvecklingen när det gäller väg- och trafikinformation. De metoder jag har använt har varit kvalitativa intervjuer, litteratur- och dokumentstudier samt komponenterna problem- och målanalys i metoden Förändringsanalys enligt FA/SIMM.

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Background: Myocardial infarction is the most common individual disease among people in the west world. In Sweden there are over 50 000 women and men who get myocardial infarction every year and about 40 % of them dies. Exercise training is one part of cardiac rehabilitation and since 1980 Sweden use the guidelines from that time. Aim: The aim was to review exercise-training modalities in cardiac rehabilitation after myocardial infarction and the physiologic- and psychological effects. Method: Facts were obtained by searching through the database PubMed for articles published from 1994 and ten years forward.

AimThe aim of this study has been survey the possibilities for short-term stays in the Stockholm Archipelago for people without their own means of transport, own equipment and/or experience of outdoor life.To fulfil this aim, the following questions were formulated:? What communications are available to chalet parks in the Stockholm Archipelago?? What overnight accommodation is available in the chalet parks in the Stockholm Archipelago?? What activities can be pursued in the Stockholm Archipelago?? What is the financial cost of travelling to and staying in the Stockholm Archipelago for a week?MethodWe chose to use six interviews and three observations in order to gain as much insight as possible. Interviews were conducted with Claes Petterson at Waxholmsbolaget, a company that provides transport services in the Archipelago, and with managers for five chalet parks: Rolf Andersson for Finnhamn, Per Englund for Grinda, Arne Johansson for Rånö, Pär Hjärtström and Peter Hösöyen for Gålö and Anders Bedinger for Gålö and Nåttarö. The interviews were recorded in writing and on tape. Observations were carried out at three chalet parks, i.e.

AbstractThe tests work is about the subject "synergism of steel and concrete."The construction sector is in a strong competition and the different companies in the PrefabMarket has ever tried to develop new design solutions that are efficient and environmentallyfriendly.The purpose of this report is to highlight different aspects of interaction and size up a columndimension and to examine its efficiency and load capacity as Eurocode 3 and Eurocode 4. A sizing chart that describes the relationship between the torque and normal force shouldalso be made of the interaction . .

Purpose ? The purpose of this thesis is to develop a total cost model for container transports and create a tool that calculates a suitable transport quantity from an economic view, which fulfills the demands on delivery service. To achieve this purpose the following questions will be answered:Which costs are affected by the decision between the two transport alternatives LCL and FCL?   How does the decision of sending product LCL or FCL influence the delivery service?  How can a tool be constructed to simplify the decision-making process regarding the choice of sending products LCL or FCL?  Method ? A total cost model was developed. This model is supported from existing literature.

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Denna rapport är resultatet av en analys som gjorts vid Vest-Woods fabrik i Forserum under våren 2007 i syfte att reducera interna transporter. Vest-Wood AB i Forserum tillverkar dörrar för den svenska marknaden men förser också en annan fabrik (SdrFelding i Danmark) i samma koncern med dörrstommar. Materialhantering för att förse Sdr Felding fabriken med dörrstommar medför i dagsläget mycket interna transporter i Forserumsfabriken. För att klara ojämn efterfrågan från Sdr Felding fabriken samt för att kunna jämna ut sin egen produktion har Forserumsfabriken valtatt lagerföra de tolv artiklar som beställs mest frekvent från Sdr Felding fabriken. Buffertlagret vid Forserumsfabriken där artiklarna lagerförs är placerat ca 200 m från produktionen vilket medför mycket intern transport för hantering av dessa.

The initiative for this project was taken by Benteler Engineering Services, as a result of having identified areas of improvement, in designated accessible areas like the wheelchair spot onboard buses. Depending on a wheelchair to be able to move around can understandably be challenging.Public transport is a common good in today`s society, however despite the measures taken towards adjusting to accessible needs, the majority of those being disabled chose different alternatives of transportation. This is due to reasons such as the drivers' poor attitude, furthermore the limitations of the space allocated to accessible needs, as people with strollers also use these spots onboard. Also, some wheelchair users find the rides unsafe, as they could easily fall over during without the appropriate space for them onboard the buses etc. These are only a few reasons why other options are sought out, i.e.

This study was made as a part of a feasibility study on a polishing wetland at Rimbo wastewater plant (wwp) in Norrtälje municipality. The wwp had to decrease the nitrogen discharge to reach the limit 15 mg tot-N/l. The nitrogen in the outlet was mainly in the form of nitrate, hence the wetland mainly ought to support denitrification. The proposed area for the wetland was situated right next to the wwp and was already in the municipalitys posession. One aim of this study was to examine what spieces of plants needed to achieve highest possible denitrification.
