In Sweden the most common type of road traffic accidents involving passenger cars are single accidents (where only one vehicle is involved). The aim of this thesis is to analyse how these accidents occur, and present recommendations on how to reduce the number of deaths. Data has been collected from the Swedish Transport Administration?s in-depth studies of fatal accidents. Road traffic accidents with fatal outcome that happened on public roads during the years 2007 to 2009 have been studied.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

PSI-N is one of the subunits in eukaryotic Photosystem I (PSI) and is located on the lumenal side of the thylakoid membrane. It is known to interact in the electron transport chain between plastocyanin and PSI, but the mechanism behind the interaction is still unclear. To achieve a better understanding of PSI-N´s role in the photosynthesis it is necessary to develop a method for purification of PSI-N. The goal with this project was to design a plasmid that encodes a fusion protein containing PSI-N. With use of proteases the fusion protein can be cleaved into purified PSI-N.

This paper will discuss the proposed reintroducing of a final degree in upper secondary school. In a public government inquiry that was released in March 2008 a proposal about reintroducing a final degree in upper secondary school was presented. A final degree has not been a part of the upper secondary school science 1968. Why was the system with a final degree abounded and why do the government want to reintroduce it?Research in pedagogy has through the years presented numbers of theories about assessment.

This report is a result of a degree thesis at Luleå University of Technology together with Stram AB in Växjö. The project aimed to develop a size reducible bed, that gets small when folded and has a new slim design. The development of the new folding bed had the purpose to give Stram AB new ideas of how guest beds can look like and be used in the future. Information about Stram´s products and also information of other similar products on the market was gathered. A visit at a store, internet and interviews gave grater insight of the market, and of customer needs.

Nature conservation on certified small private forest owners- a comparison between the two certification systems FSC and PEFC in southern Sweden Today two different certification systems are used in Sweden to certify forest, FSC (Forest Stewardship Council) and PEFC (Pan European Forest Certification). During the last years certification of forests in general and different certification systems have frequently been debated. FSC is a globally widespread system and about 10 million ha out of 23 million ha Swedish forest is FSC-certified. The FSC-standard is mainly used by major forest companies and to some extent also by smaller private forest owners. PEFC is a European system and about 2 million ha Swedish forests is PEFC-certified today.

Syfte: Att ur ett intensivvårds- och röntgensjuksköterskeperspektivbeskriva och jämföra upplevelser och erfarenheter av att utföra CT-hjärna på enneurointensivvårdsavdelning. Metod: En deskriptiv intervjustudie medkvalitativ design användes, där åtta sjuksköterskor inom professionernaröntgen- och intensivvård deltog. Resultat:Intensivvårdssjuksköterskorna såg fram emot att apparaten skulle börja användaspå avdelningen, medan röntgensjuksköterskorna upplevde en frustration över attför lite tid och resurser avsatts för att kunna utföra undersökningen påavdelningen på ett bra sätt.  Intensivvårdssjuksköterskornaupplevde en tidsbesparing att kunna utföra undersökningen på avdelningen medanröntgensjuksköterskornas uppfattning var att man hann undersöka färre patientertotalt under samma tid. Resultatet visar också att sjuksköterskorna i bådagrupperna är medvetna om riskerna med intrahospitala transporter och ansermöjligheterna att utföra CT-hjärna på avdelningen som fördelaktigt förpatienten ur säkerhetssynpunkt.

This thesis is about making a support for barcode readers and RFID readers on a computermounted in heavy vehicles. The computer has several applications designed for heavyvehicles such as an order handling application. The goal was to suggest an architecture toimplement a support for the readers. The architecture should be independent of whichmanufacturer who has made the reader hardware that was connected to the computer.At first a theoretically study was made around RFID technology and standards for thetransport and supply sector. Then the architecture was developed and a demo implementationwas made.The conclusion of this thesis is to implement support for barcode readers with a wedgeapplication.

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Undersökningar visar att det är mycket problem att tillgodose djurens välfärd vid konventionell slakt gällande transport, uppstallning och hantering (Broom, 1993). Därför är det intressant att ta reda på vilka alternativ det finns till konventionell slakt. Ett exempel är mobila slakterier. Det här arbetet tar upp dess för- och nackdelar ur djurvälfärdssynpunkt. Det finns idag många rapporter, som tar upp mobil slakt ur en ekonomisk synvinkel (Helgesson & Pettersson 2000) och den praktiska hanteringen (Benfalk et al., 2002) efter avlivningsmomentet men mindre om hur djurens välfärd påverkas. Det finns olika utformningar på mobila slakterier.

I denna studie intervjuades fem gymnasielärare i naturvetenskapliga ämnen kring att undervisa och lära utanför klassrummet. Frågeställningarna i detta arbete är; Varför skall man undervisa och lära utanför klassrummet? Vad finns det för hinder eller nackdelar med att undervisa utanför klassrummet? Alla lärare var positiva till att använda sig av undervisning utanför klassrummet men de framförde alla att de inte tyckte att de gjorde det tillräckligt mycket. Fördelar som dessa lärare kunde se med att välja att ha undervisning på en annan plats än klassrummet var att det gav en bättre verklighetsanknytning, var lättare att arbeta ämnesövergripande, gav en god variation i undervisningen, platsen har positiv betydelse för minnet, det kunde öka motivationen och intresset hos eleverna att lära, och slutligen att det förbättrar sociala interaktioner mellan såväl elever som mellan elever och lärare. De hinder eller nackdelar lärarna kunde se med att använda sig av undervisning på en annan plats än i klassrummet hade hos de flesta sin grund i tidsmässiga och schemamässiga problem men de var även en tveksamhet kring den pedagogiska vinningen, karaktären på de naturvetenskapliga ämnena och deras kursplaner, att eleverna var ovana och att lärarna inte kände sig trygga och bekväma i att ha undervisning utanför klassrummet. Skolans geografiska läge, väder, transport, riskbedömningar, saknat lärarsamarbete och saknad av lämpliga läromiljöer utanför klassrummet uttrycktes också vara hinder för att ha undervisning utanför klassrummet..

ABSTRACTDuring the last decades, environmental impacts have increased significantly, much due to the great traffic flows within cities. Therefore, to reduce these impacts and encourage a healthy way of living, it has in recent years become vital to generate safer and more sustainable and flexible modes of transportation. In order to do so, authorities and physical planners must work together to find viable solutions to incorporate in the infrastructure and offer alternative transport modes ? such as walking, cycling and public transportation. The purpose of this thesis is to examine the development of the cycling infrastructure in the city of Västerås and whether it is possible to expand bicycle commuting alongside public transportation. The thesis consequently aims to study how different physical planners within Västerås municipality work with traffic related questions.

The debate about women and equality is a very burning issue in the Swedish society today. There are a lot of articles, TV-programs, books and web sites treating the position of female leaders today. There are also a lot of myths strongly attached to our minds hindering the equalization process between men and women.The main purpose of our study was to look at women as leaders and identify potential tendencies in businesses sectors dominated by mainly men or women. We also wanted to find out whether leadership behavior is more or less oriented towards relations- or task in any of the chosen sectors. It was even in our interest to see if our chosen respondents supported the myths in our society about male and female qualities.We interviewed 20 women in four different sectors, two dominated by men (Computer/It, Transport) and two dominated by women (School, Healthcare).
