Utmattning av järnvägsbroar i armerad betong : Enligt eurokoder

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.

Locally produced pork ? Västra Götaland

The interest for locally produced food has increased the last couple of years, and some consumers have a willingness to pay a premium for niche products like locally produced food. At the same time it seems like the Swedish pig production are in a negative development period. This study tries to see if locally produced pork could be a possible factor which might affect producers in the county of Västra Götaland views on different aspects regarding their production. Consumers of pork and their point of view regarding locally produced pork were also studied. Surveys to consumers and producers were constructed. Although previous studies claim the opposite, in the two locations (Högsäter and Uddevalla) where the consumer survey were performed, there were more men than women that always bought locally produced pork.

Tidsupplösning vid miljövärdering av fjärrvärme : Kontorsbyggnad med solvärmeproduktion - en fallstudie

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

Hörselnedsättning hos barn och ungdomar till följd av platinabaserad kemoterapi - en beskrivande litteraturstudie

Success in treatment with platinum-based chemotherapy against different types of cancer tumors is limited by side-effects such as hearing loss which can have a large impact on the individual`s quality of life. It is of great importance to continue with studies that address this complex of problems.Objective: The aim of this literature review is to investigate the impact of platinum-based chemotherapy on hearing in children and adolescents treated for different types of cancer.Method: A descriptive review of literature was made based on sources from 15 different studies on the impact of platinum-based chemotherapy on hearing in the target group.Results: The survey of the studies shows that platinum-based chemotherapy causes incidence of hearing loss by differing degree in the target group. Dosage of a platinum-based substance appeared to be the most significant factor. Treatment with both cisplatin and carboplatin was more ototoxic than treatment with only one of these. Greater risk for hearing loss was to a higher degree observed in younger children.


Miljöcertifiering av hotellverksamheter : varför miljöcertifiera?

The awareness regarding environmental issues is increasing and as a result a large number of products are eco-labeled. This enables the consumers to make enlightened environmental decisions when purchasing products. Eco-labeling is no longer for products only, but also for services like hotels. It?s difficult to determine what it actually means to eco-label a hotel and what kind of benefits it includes.

To reach the goal of the study, several qualitative interviews were made with the following questions as base:? Which factors does the student consider to be of importance for their self-esteem and self-confidence in the interaction with teachers?? How does the student feel that these factors were affected concerning their self-esteem and self-confidence?During the analysis and systematization of the transcribed interviews, five factors emerged that effects self-esteem and self-confidence.

Flygplansavisningens miljöpåverkan vid svenska flygplatser

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

Stress test methods : a potential approach to hurry up shelf-life tests on oat products

Motiverande faktorer i det dagliga arbetet hos undersköterskor

AbstractThe aim of the present study was to investigate what kind of factors contributed to motivate a group of nurses at a nursing home in western Sweden to to perform their work. Furthermore, the authors wanted to investigate whether the staff nurses felt that the leader helped to increase or reduce the perceived motivation to perform such work, and the way in which staff nurses perceived their relationship to the leader. The study is based on Herzberg's (1959) two-factor theory, Hackman and Oldham's (1980) work designs theory and Leader-member exchange (LMX) theory, and those theories are the basis of the study's structure. The study was of a qualitative property, interviews were conducted with seven nurses and was structured, the questions concerned their subjective experience of motivating factors in their everyday work. The results of this study demonstrated that respondents experienced confirmation, the meaningfulness of the work, work colleagues, beneficiaries of care and residents' families as contributing factors to motivate them in their daily work.

Inventering av värmelager för kraftvärmesystem

When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

?Vilka faktorer kan påverka försäljningsmålet inom kartong- och pappersindustrin? : ? En fallstudie på Korsnäs AB

AbstractCompanies in the Swedish process industry has for a long time spent a lot of capital in high-tech development, which have given them increased ability to compete with high quality and excellent technical knowledge, which has given them greater opportunities to grow on the market. But it?s not enough to achieve success with new products and service; it must also be consistent what market wants and preferably something exceptional. The purpose of this study was to determine the factors that are predominantly success factors and how they may affect the sales target of a new product, in this case Frövi White. Another objective of the study was to examine how Korsnäs Frövi communicates and transforms information as requests and demands from customers into refined material. To obtain relevant information to the study several interviews with respondents from most of the value chain in Korsnäs Frövi has been carry out.

Användardriven design : Utveckling av interaktiv karriärhemsida för Ericsson

Hemsidan är den enskilt största kommunikationskanalen mellan Ericsson och potentiellt framtida anställda. Företaget har idag problem med att den globala karriärhemsidan inte uppfattas som användarvänlig av särskilt studenter, och detta examensarbete syftar till att definiera krav för hur en global karriärhemsida bör utformas för att vara användarvänlig och välkomnande för studenter.Med en användarcentrerad designstrategi och en teoretisk bas inom interaktionsdesign och human factor syftar avhandlingen till att förstå vad studenterna efterfrågar och hur Ericsson kan möta och överträffa dessa förväntningar. Tester, workshops, utvärderingar och intervjuer har använts för att iterativt utveckla en prototyp och kravspecifikation.Studien visar att det finns två huvudsakliga typer av användare att designa för: de med ett tydligt mål att hitta ett jobb och de som försöker ta reda på om företaget är av intresse. Vanliga känslor hos användarna att ta hänsyn till ärångest, ensamhet, beslutsamhet, spänning och glädje. Några av slutsatserna kring den befintliga karriärhemsidan är att den vänstra menyn inte är organiserad på ett sätt som hjälper användaren att hitta vad han/hon letar efter, innehållet i mitten är för allmän och tråkig för många användare och högerspalten används sällan, trots att den innehåller vissa användbara funktioner.

Vidareutveckling och utvärdering av operatörsplatser på svenska stridsfartyg

The ability to handle potentially dangerous and hostile situations on a military vesselrequires that the equipment works effectively with the personnel that use it. It is importantthat this equipment can be used by different people. An operator on a military vesselshall be able to handle information about hostile threats, navigation and the steering ofunmanned vehicles. A operator console should therefore be constructed in such a waythat the operator can handle a large flow of information. And the information given bythe technical system should be displayed correctly to facilitate the operators ability tohandle and interpret the information correctly, in order for the operator to make thecorrect decision at any given moment.
