Bachelor thesis Re : bottle
There is a new beverage container on the market, a bottle made out of pure aluminum as a replacement for the traditional container made out of glass. This new container has the potential to reduce both cost and pollution during transportation, the lighter and stronger construction has every advantage compared to the old one in glass. The new container has every possibility to make it on the market. Some of the biggest brands within the soft drink market already use these bottles in countries without any recycling demands like: Coca-Cola, Heineken and Pepsi. The only thing stopping these brands from the Swedish market is the lack of a functional return system, there is only one company that uses the bottle in Sweden today and they take care of their own used bottles.
Automatic Trimmerhead
Automatic trimmerhead is an examination project for making an automatic trimmerhead for grass trimmers with the user and functionality in focus. Our perception is that a happy user is a user who can pick up his or her trimmer, use it and put it back to its place when the job is done. It should not be necessary to interrupt work and perform maintenance on the machine just to make it work as promised.The project has been made in collaboration with the company Husqvarna, which is one of the biggest actors dealing with garden machinery on the market. Together we determined the project goal, ?To invent, construct and test a brand new concept for how an automatic trimmerhead can look and function?.At this day there are several different automatic trimmerheads on the market, both semi and fully automatic.
Larynxmask eller endotrachealtub prehospitalt ? styrkor och svagheter : Litteraturstudie
ABSTRACTBackgroundWhen faced with an unexpected cardiac arrest the ambulance nurse is in responsible for taking advanced actions to create a clear airway. Two accepted methods for this is endotracheal intubation and application of laryngeal mask.AimThe purpose of this study was to examine the use of endotracheal intubation compared to application of the laryngeal mask in unexpected cardiac arrest.MethodLiterature study with quantitative approach. A systematic search of 21 articles comparing the laryngeal mask with the endotracheal intubation has been made using Pub-Med and CINAHL. A quality review according to Forsberg and Wengström has been made.ResultsLaryngeal mask had a higher rate of successful applications compared with endotracheal intubation. Time for applying the laryngeal mask was shorter in seven out of ten of the studied articles.
Utveckling och konstruktion av dämpare och låssystem för vågkraftverk
The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.
Nya uppgifter-nya uppdrag
The underlying purpose of this study is to see whether a library focused solely on providing literature in other languages than Swedish serves as a unifying, integrating force, or as an agent for division and exclusion. The study focuses on the International Library in Stockholm. The authors have created a profile of the visitors of the selected library, concerning their characteristics, their library habits and their perceptions of the International library. This profile has then been compared with the staff?s perception of the visitors as a group.
Dubbelprövningsförbudet avseende skattetillägg och skattebrott : - en utredning av införandet av regeringens förslag gällande en spärreglering samt ett samlat sanktionsförfarande ur ett rättssäkerhetsperspektiv
A tax penalty is an administrative penalty and is levied when the tax obligated provides false information for the guidance of their own taxation. Further can the taxpayer also be punished for tax evasion for the same false reporting. However, this is contrary to the European Convention that we should not be tried or punished twice for the same crime. The Supreme Court has through practice from 2013 ruled that the right not to be punished twice for the same offense shall include the system in force concerning tax and tax offenses. The Supreme Court has by this judgment determined that the system of penalty and tax evasion is not compatible with the dual test ban.In the light of the judgment the Government submitted in November 2014 a draft to the council regarding double test ban regarding penalty and tax evasion.
Utformning & placering av vädringskanaler i ett passivhus, drivet av naturliga krafter
A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.
Beräkning av värmeförluster och energieffektivisering av elbussar
The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå. The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.

The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.
Det kan vara farligt att ligga lågt - om stadsplanering inför stigande vattennivåer : Exempel från Göteborg, Kristianstad och Arvika
In this study is being examined how cities can be planned in the face of rising water levels and extreme weather, due to the changing climate. The starting point has been to investigate how the problems can be tackled and how the positive sides of water in the city can be strengthened, and synergy effects and greater sustainability be achieved thereby. The method has been literature studies and case studies containing interviews and visits. Göteborg, Kristianstad and Arvika have been studied for discussions and ideas about adaptation. Today, building near water is very popular which brings both advantages and disadvantages.
Ändrad användning av stationshus : fallet Ormaryds station ? ett stationshus med betydande kulturvärden
Acquiring a former station building can mean that the property owners must familiarize themselves with a lot of planning and building regulations. After the new Planning and Building Act code into force in 2011, the responsibility lie on the developer to ensure laws and regulations. Based on the regulatory framework that is available occurs sometimes balance issues, between care requirements and building codes. The station building in Ormaryd was acquired in 2009 by two individuals who intended to accommodate office and retail space in the building. In doing so a new local plan of the area was established, including regulations on how the building could be used. By including road safety and noise, the risk was not considered appropriate to use the station building for housing.
Konstruktion av infästning till dysa
The goal of this thesis is to design an attachment between a duct and a pod. A pod is what could be compared to an outboard engine for larger vessels. The pod is placed on the outside of the ship?s hull and can rotate 360 ?. A duct is a large steel ring that can be placed around the propeller on the pod to increasethe propulsion force of the ship in lower velocities.
?Det här var dagen då anonyma tonåringar via sociala medier startade ett upplopp i Göteborg? En studie över gestaltningen i fyra svenska tidningar av gatuoroligheterna vid ?Instagram-händelserna? i Göteborg år 2012.
On subsequent days, the 18th and 19th of December 2012, large groups of young people gathered to protest in the centre of Gothenburg. The gatherings mainly occurred outside two high schools: Plusgymnasiet and Framtidsgymnasiet. The reason behind the gathering has often been explained by the young people?s reaction to an Instagram account, on which offensive pictures and comments of and about young boys and girls had been published. As a reaction to the protest, police force including helicopters and mounted police, was sent to the streets.
Nordiskt försvarssamarbete i åtstramningens tidevarv : En studie av förutsättningar för det norsk-svenska försvarssamarbetet
This study uses European researcher Tomas Valasek?s hypothesis about factors required for defence cooperation in order to achieve conditions which can be successfully applied to the Nordic defence cooperation NORDEFCO. The study uses only Norway and Sweden on the grounds that they are the original actors and the Driving forces behind the defence cooperation. The factors studied are; the countries' strategic culture, solidarity and trust between countries, similarity in military forces, if similar conditions prevail in the defence industry and if the intentions of cooperation have been clarified.Mainly government documents in the form of propositions, orientations and defence documents are studied, together with previous research in this area and, especially, interviews with representatives of NORDEFCO at military level and policy level as well as outside perspectives from the military attachés in each country. With the intention of studying the extent to which the factors Valasek features may prove to be significant in assessing the conditions for enhanced cooperation in NORDEFCO, the study raises the question of how it is possible to find expressions for the factors.
GPS- & GIS-användning i drivningsprocessen hos Stora Enso SKog AB :
GPS (Global Positioning system) and GIS (Geographical information system) has been used for planning and inventory in the forest sector for more than ten years. The last years the development has come to equip harvesters and forwarders with GPS and GIS (GIT).
The goal with this study was to reach a basis for decision, how Stora Enso Skog should continue its investment in GPS and GIS in harvesters and forwarders. To reach this basis for decision, possible advantages and benefits, disadvantages and problems in the harvesting process was evaluated. The study was made as an interview study with four harvesting managers and ten machine teams. To secure the quality of the results an interview questionnaire was made before the interviews were done.
The results showed that GIT will make the harvesting managers work easier.
