Utformning av sidoområden med hänsyn till vägens livscykelkostnad

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Från vaggan till grinden, en livscykelinventering på ett par bomullsbyxor

Our common future involves many important challenges. People and nature need to improve the relationship in order to reach an ecologically sustainable development. In a society where consumption of products steadily increases, the consumer awareness about social and environmental issues connected to the products becomes an importent factor. More and more companies choose to work more actively with these issues and more and more products get labelled by some of the eco labelling organisations. From the cradle to the gate means that a study has been done on a part of a products life cycle.

Smärtskattning med validerade smärtskattningsinstrument - en interventionsstudie

AbstractPain among patients in their final stage of life is a commonly occurring problem. Results fromthe Swedish Register of Palliative Care (SRPC) indicate that validated instruments forassessing pain are rarely used. Nurses' insufficient knowledge of pain and pain treatmentmethods may be a cause of maltreatment of patients who suffer from pain.The goal of this study was to determine whether training within the area of pain, painassessment and pain assessment instruments increases the use of validated pain assessmentinstruments utilized by nurses working in care homes for patients in the final stage of life inthe city of Uppsala.Method: A quantitative and quasi-experimental design was selected to perform the study.The intervention study that was used consisted of one training session where onequestionnaire was given before and one after the time of training. Register data were collectedfrom the SRPC given the question of pain assessment before and after the intervention.Results: The study showed that nurses more often used pain assessment instruments after thetraining session. The results also showed that nurses to a greater extent than before alternatedbetween the two validated pain assessment instruments that were introduced at the trainingsession.Conclusion: The results showed that when nurses at care homes are given training in the areaof pain and pain assessment they absorb and use the newly acquired knowledge in theirclinical work..

Om New Economy Firms strukturella utveckling längs med livscykeln och dess implikationer på organisationernas entreprenörskap - En fallstudie av tre svenska New Economy Firms

New Economy Firms (NEFs) are considered being important drivers of economic development and growth in Sweden. Also, entrepreneurship is a widely discussed topic that is considered being essential for firms that are making business in a fast moving landscape. Usually, the growth of companies is put in context of the life cycle. The life cycle further implies that as a company moves from the startup-stage along the curve, the organizational structure increases. Further, increased structure is claimed to impede the entrepreneurial culture within the firm.

Upprustningsmetoder för en bankropp : En jämförelse ur ett LCC-perspektiv

In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.

Hållbar Textil Produktutveckling : med växtfärgning

Författarna har haft ett samarbete med Panduro Hobby i samband med deras årliga miljökampanj. Syftet med examensarbetet har varit att med hjälp av befintliga produktutvecklingsprocesser och livscykelanalyser (LCA) ta fram en hållbar textil produkt med växtfärgning. Tanken var att konsumenter sedan själva skall kunna ta fram och växtfärga denna hållbara textilprodukt. Miljömedvetenhet och hållbarhet inom textilindustrin är ett aktuellt ämne. Trots det saknar dagens konsumenter förståelse för textilindustrins påverkan på miljön och har bristande kunskap om textila material för att kunna göra miljövänliga val ute i handeln.

En vidareutveckling av förvaltningsmodellen vid systemförvaltningsprocessen

Detta arbete behandlar problemområdet systemförvaltning och är en vidareutveckling av förvaltningsmodellen vid systemförvaltningsprocessen. Vid systemförvaltningsarbetet finns det olika förvaltningsmodeller som kan vara ett stöd vid taktisk och operativ styrning samt administrativ kontroll.Systemförvaltningsmodellen består generellt av sju olika rekommenderade delmodeller där bland annat systemförvaltningsprocessen ingår. Modeller för systemförvaltningsprocessen bör förenkla, effektivisera och ge stöd när systemförfrågningar samt systemkrav inkommer från verksamhetsledningen eller systemanvändaren. Undersökningen i detta examensarbete fokuserar på en vidareutveckling av modellen Application Maintenace Cycle (AM/Cycle) som utvecklats av Peder Brandt.Vidareutvecklingen i detta arbete resulterar i en modell för systemförvaltningsprocessen, vilken benämns Application Maintenace Schedule Cycle (AMS/Cycle). Litteraturstudier och intervjuer har påvisat vissa svagheter med modellen AM/Cycle, vilket tagits i beaktande vid vidareutvecklingen av AMS/Cycle.

Delaktig eller inte, det är frågan : En intervjustudie kring elevens delaktighet i bedömning i svenska utifrån bedömningsstöden »Läsutvecklingsschema» och »Nya språket lyfter!»

Assessment of the level of the pupils´ knowledge and understanding are important parts of teaching. There are diverse ways to do this and many different tools to use.The purpose of this study is to explore, through qualitative interviews, how five teachers work with assessment. The focus lies on both how they work with assessment in general and how they use the assessment tools called »LUS» and »Nya språket lyfter!». The pupils´ participation in their own education is an important part of the Swedish curriculum, which is why the study also focuses on how the informants work to enable the pupils´ participation in the assessment and in their education.The informants all think that both assessment and the pupils´ participation in the assessment are important, since teaching is easier when the pupils are aware of what they need to know and learn. Many of the informants express that time is an issue when it comes to making the assessment trustworthy.

Spårtaxisystem i Uppsala

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.
