Konstruktion av steghållare till brandbilar

High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.

Vindfällning i naturliga och skapade bryn och kanter :

The aim of this work was to study if the edge of the forest is more resistant to heavy winds than the trees located further in from the edge, and how this edge effect changes between different types of tree species and site types. The data was collected from an electric power line going from the north to the south of Sweden. The mean value of the clearcutted area around the power line was 120 meters. The main direction of the storm in January 2005 was west-southwest and thus the power line was a perfect place for gathering a large data set. The main parameter studied was the damage frequency at the edge of the forest compared to the trees located further in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated. The results showed a distinct edge effect. The edge of the forest had clearly lower damage frequency for all tree species. A marked difference was observed between tree species and damage frequency.

Tycho Hedéns Väg : trafikrum blir stadsrum

Tycho Hedéns Väg in Uppsala has evolved from being a through fare passage and highwayto the oversized road frame running through the city it is today. At the present time, dueto the relocation of the E4 highway east of Uppsala, Tycho Hedéns road creates a barrierbetween the north eastern area of Uppsala and the remaining parts of the city centre. Theroad is designed to endure heavy traffic and high speed limits, generating a surrounding urbanarea were inhabitants are complied to follow the standards set for a high traffic-accessibleenvironment. Furthermore, the heavy traffic has led to the turning of both urban roadsidesaway from the actual road. The aim of this project and proposal is to show the possibilities ofhow the innate features of Tycho Hedéns road can be used more advantageously to mend thecity area of Uppsala.

Positiv särbehandling och kvotering

The purpose of the essay is to investigate SVT: s (Swedish Television) attitude to allocation of quotes and preferential treatment. In Sweden there is only one law, which allows preferential treatment ? the law of equal opportunities. This law prohibits discrimination between women and men. The profession of camera operator and editor have been viewed as masculine in accordance to heavy lifting and high technology, this considering being hindrance to women.

Detection of mutations in dihydropteroate synthase (dhps) and dihydrofolate reductase (dhfr) in Plasmodium falciparum in eastern Sudan

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

Röjningsbenägenheten bland privata skogsägare : en enkätundersökning bland medlemmar i SÖDRA

The intensity of cleaning declined dramatically in the early 1990?s in the Swedish forests. Recession, an economic depressed forestry and the new law of silviculture from 1993, where the duty of cleaning was removed have been considered as sources to the decline. This has led to a situation where huge areas of forests are untouched, which can lead to negative effects for those stands in the future. The purpose of this thesis was to find out how the individual landowner acts and feel when it concerns cleaning activities. Has the landowner noticed Södra?s campaigns about cleaning and what sort of measure should Södra implement to increase the members? cleaning activity? The thesis is based on a opinion poll made through a random draw among all Södra?s members.

Utformningen av ett förstärkt skruvförband på en differentialväxel i bandvagnen BvS10 : Analys av olika förband med hjälp av CATIA och MATLAB

This is a thesis presents a differential gear which is found in a tracked vehicle called BvS10. The tracked vehicle is manufactured by BAE Systems Hägglunds AB in Örnsköldsvik, Sweden. The differential gear has a bolted house. The differential meets the requirement specifications, but the problem is that the bolts are sheared off because of the extreme torque that the differential is exposed to resist.Previous report on the differential show pictures of bolts which have been sheared off at the threads. This report is also includes three lists that explain seven different proposals which some are approved and some are not, and the report also presents the force, tensile, and shear stress.In a bolted connection there is both axial tension stress and radial shear stress, which can lead to wear out and broken bolts.

Doby?ins fokus : Detaljerna och debatten om Gud i ?urkina rodnja

Nathan Söderblom, Swedish archbishop 1914 - 1931, understands his role as bishop from an integrated theological conception that episcopacy is a gift to the church and the apostolic succession a heritage of utmost value. Episcopacy is an important tool to make the churches come together. in his work for peace during the Great War it was through his position without any power that he could approach the politicians. His calling was not only for Sweden; he had a responsibility for the whole world. In the Ecumenical Cope for the 1925 Stockholm meeting Söderblom expressed his views on the importance of the Uppsala see.

Insatser och åtgärder för främjandet av laddelbilar i Sverige

To achieve the goal of fossil independency in the Swedish vehicle fleet in 2030, it would be important to substantially increase the proportion of electric vehicles, both BEV:s (Battery Electric Vehicles) and PHEV:s (Plug-in Hybrid Electric Vehicles). The Swedish Energy Agency has funded numerous research and development projects about electric vehicles in recent years. An important task for the Swedish Energy Agency is to allocate state funds to those projects with the greatest potential to contribute to increased establishment of electric vehicles in society. The purpose of this work is mainly to understand the efforts and measures that can make the market for electric vehicles to grow. The report can contribute to a better understanding of how far the research on electric vehicles has come and what has to be done in the future to promote the establishment of electric vehicles. Another aim for this report is that it should serve as a basis for future decisions by the Swedish Energy Agency on which projects that will be funded with state funds.

Band eller hjul? : Lämpligt fordon för EOD-specifika behov i Afghanistan.

The background to this paper is the events that have taken place in the Swedish area of responsibility in Afghanistan where Swedish troops have been ambushed by the insurgents. Although the troops primarily where riding in Toyota Land Cruisers they had no casualties. I think that the Swedish force needs other vehicles that can be armed and are armoured.When I compared three different types of armoured vehicles, I found that PTGB 6 is the vehicle of choice, according to the special needs that a Swedish EOD-squad, their task and their equipment have. .

Fria Ventiler : Olika ventilstrategiers effekt på cylinderströmning, emissioner och prestanda i en heavy duty dieselmotor

En del fjällvandrare tycker att det är för tungt att gå med en stor ryggsäck, ett problem som har givit upphov till en idé om ett avlastande hjälpmedel. Företaget Prodelox AB har sedan tidigare påbörjat utvecklingen av detta hjälpmedel. Under detta examensarbete har ett koncept utvecklats med den initiala studien som utgångspunkt. Produktens grundidé är i dagsläget sekretessbelagd och kommer tyvärr inte att redovisas i denna rapport.En användarstudie genomfördes vilket resulterade i en kravspecifikation, produktens definition, samt en djupare bild av fjällvandring och andra friluftsaktiviteter. Denna djupa inblick möjliggjordes med hjälp av context mapping-metoden.
