Kartläggning av faktorer som kan minska antalet återinkopplingar i elnätet
Vattenfall Eldistribution AB distribuerar el till ca 900 000 kunder i Sverige. Det handlar om både privatkunder och företagskunder. Enheten Nätdrift vars driftcentral är placerad i Trollhättan har till uppgift att se till att elnätet är spänningssatt och att man skall minimera avbrottstiderna.Då dagens samhälle är allt mer beroende av störningsfri leverans av el är det viktigt att kartlägga faktorer som orsakar korta avbrott på nätet. Ett kort avbrott definieras som ett avbrott som varar allt från 100 millisekunder till 3 min. I myndigheternas föreskrifter finns inga krav angående hur frekvent korta avbrott får förekomma i elnätet, då dessa avbrott oftast är orsakade av åska och därmed omöjliga att förutse.
Hållbar avfallshantering : Ur ett ekonomiskt- och miljöperspektiv
Economy and environment has for a long time been studied separately and seen as incompatible. With a growing society and increasing pressure on environmental issues the need of a new economy with the environment included is necessary. This study examine if European Union´s picture of the waste hierarchy match the reality. Since the purpose with the waste hierarchy is to benefit environmental and economy. A survey was made over Käppalaförbundets waste from 2013, to see where the waste falls in the waste hierarchy.
Plackindex, gingivalindex och erhållna munhygienåtgärder hos patienter i åldern 20-26 år som har behandlats vid tandhygienistprogrammet i Kristianstad-journalstudie
The aim of the study was to examine plaqueindex, gingivalindex and oral hygiene measure among patients between 20-26 years of age, who were treated at the Dental Hygienist Programme at the University of Kristianstad. The study was performed as a dental record. All 126 subjects with records in this age were including in the study. Sixteen records (13 %) were excluded because the criteria were not fulfilled. Plauqeindex, gingivalindex and oral hygiene measures were registered from 110 records.
Rödluvan och vargen : En kvalitativ textanalys av debatter och adaptationer i barnlitteraturen
This two years master?s thesis is a review and exploration of the Swedish debate concerning children?s literature from the 19th century to the present, as well as the evaluation and analysis of four adaptations of the tale Red Riding Hood. The aims are to identify how ideas and values regarding the role of children?s literature in society have developed over time and to contribute with a knowledge base for continued reflection and discussion on the subject of children?s reading and mediation of children?s literature in public libraries.The theory and method used in the thesis, is primarily based on the discourse analysis of Michel Foucault. I have identified four main discourses: the educational discourse, the liberation discourse, the politicized dis- course and the popular discourse.
Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.
Grundvattenskydd och markanvändning i tre olika länder- effekter för miljö och samhälle
AbstractDrinking water is an important resource on Earth both for humans and animals. Although most of the surface is covered by water only a small quantity is available as drinking water. Our manner of living creates a lot of pollution which has an environmental impact. Groundwater has a protracted turnover time in the soil and it can take many years before the effects of human impact are detected. The Swedish environmental object is ?Good groundwater quality? which aims to provide a safe and sustainable supply of drinking water today and in the future.
Seroprevalence and risk factors for bovine brucellosis, salmonellosis and bovine viral diarrhea in urban and peri-urban areas of Kampala, Uganda
Africa is expected to go through a rapid urbanization over the next four decades and the demand for food is increasing in the rapidly growing urban and peri-urban (UPU) areas. Keeping livestock in urban areas is in particular associated with health hazards. This is due to close interaction between humans and animals, and it has been shown that zoonotic diseases are increasing in urban areas. The benefits of urban and peri-urban agriculture (UPA) are related to improved food security, in particular among low-income groups. Apart from the negative public health impact of zoonotic diseases, animal disease could have a devastating impact on the economy and food security of many households in these areas.
In the present study, three important endemic diseases, including brucellosis, salmonellosis and Bovine viral diarrhea (BVD), were analyzed in regard to seroprevalence and risk factors.
Sverigedemokraternas kriminalpolitik - På stämplingsteoretisk grund
The purpose of this study is to analyze what criminological theory explanations the Sweden Democrats use in their criminal politics. The three main questions from which we assume are: How do the Sweden Democrats approach crime? On which criminological theory is the Sweden Democrat?s policy of crime based upon? And which measures and preventive methods do the Sweden Democrats find appropriate to fight criminality? Our hypothesis is that the Sweden Democrat?s reuse/reproduce the Labeling Theory and that the party with its standpoints in this area and the rhetoric used, create a risk for individuals and/or groups of people to be labeled. The labeling can then contribute to increasing crime, in the form of the self-fulfilling prophecy. Our study is a qualitative study, based on literature studies.
Diamonds from Sierra Leone: Hur diamanter påverkar konflikter
The civil war in Sierra Leone was a very complicated conflict, both in its origin as well as in its realization. Many actors, along with the diamond trade, played vital parts in making the war carry on for a decade. In this paper I will try to clarify the relations between the actors and the diamonds, first and foremost the part the diamonds played in the conflicts start and continuation. I will also show what has happened in the country and in the diamond industry after the wars conclusion. What I find is that diamonds did not play the only part in the origin of the conflict but that the poor economic state the country was in had its part.
Utvärdering av röstträning på logopedprogrammet i Göteborg
The purpose of this study was to examine if there were anychanges in quality in the voices of speech and language pathology studentsafter four years of study at the University of Gothenburg. Recordings oftwenty student voices from the first and eight semesters were evaluatedperceptually by six speech-language pathologists. The parameters judgedwere: vocal fry, glottal attacks, strain, breathiness and resonant voice, usinga scale from 0 to 10. Acoustical measures were made of F0 mean andmedian to detect possible differences between the two recordings. Theresults show a significant decrease in vocal fry, glottal attacks and strain aswell as an increase in resonant voice and a significant decrease in F0 meanand median.

Tillämpning och utvärdering av kriterier för eTjänstetydlighet och handlingsbarhet : Actability, eTjänstetydlighet, MA/SIMM
A sequence of actions in the world have influenced the information science, one of these actions is the lateral movement in how companies use their IT-systems. IT-systems today, in comparison to before, are used by companies to improve their relationship with their customers. Every year a big amount of money is spent on developing and improving IT-systems. That is why it is important to develop and create IT-systems that are clear, and which encourage, enable and simplify a user?s action.
Lakvattenrening och kontroll vid deponier : granskning och sammanställning
If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden there is a difference in discharges between the installations for landfill. If no comprehensive legal provisions is produced guidance must improve.Treatment of leachate and self monitoring system at fifteen installations in Sweden has been studied and compared. A study of literature about different treatment solutions has also been performed.
