Balansering av en storskalig vindkraftsutbyggnad i Sverige med hjälp av den svenska vattenkraften

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

Effekter av bearbetningsdjup i plöjningsfri odling

In Sweden, reduced tillage usually means non-inversion tillage, where primary tillage is carried out using chisel ploughs or disc implements. Primary tillage method is mainly determined by the desired soil loosening and the handling of soil residues. The effect of tillage depth was studied in field experiments in Skåne, Väderstad, Uppsala, Örebro och Västerås in different crops; spring oilseed rape, spring wheat, winter wheat and spring barley.The experiments generally had a randomized block design with the treatments mouldboard ploughing, deep chisel ploughing and shallow chisel ploughing, in some cases also shallow discing and no-tillage. In the experiments the following parameters were determined: seedbed properties, saturated hydraulic conductivity, penetration resistance, number of emerged plants and crop yield (all parameters were not determined in all experiments. Root growth and draught requirement were determined in two separate studies. There were no significant differences between tillage depths in non-inversion tillage in seedbed properties, plant emergence or root development.

Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie

Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.

We live in an exciting society, characterized by continuous changes and challenges. The effects of the globalization are widespread. The continuous flow of people, capital and goods follows in the wake of advances in communications, transport and information technology, resulting in a changed situation for different stakeholders in the society. This situation leads to increased cooperation and exchange, but also increased competition. The primary means of collecting empirical data for this study was interviews and a document study.

Effektiva återkopplingsverktyg för elanvändning : En studie som syftar till att identifiera utvecklingsmöjligheter för att uppnå ett mer hållbart energisystem år 2030

Feedback tools support electricity users within the Swedish residential sector to increase their knowledge of electricity and the electricity market as well as to become more aware of their electricity consumption, which in turn encourages a reduction and an increased flexibility of electricity use. The primary aim of this study is to identify and analyse how existing feedback tools can be improved, to ensure that they contribute efficiently to the achievement of the EU objectives congruent with a more sustainable energy system in 2030, emphasizing: greenhouse gas reduction, increased energy efficiency and an increased share of renewable energy. In order to reach the primary aim of this study, existing feedback tools have been identified and mapped and interviews with feedback tools providers have been conducted. The study is limited to three research areas: the practical functions of feedback tools, available technology and the use of feedback tools.The use of more efficient feedback tools will provide an increased success rate for energy management, which includes both behavioural changes and energy efficiency. According to the results from the interviews conducted for this study, an increased use and user frequency is important to utilise the energy management potential.

Användarorienterad förarsituation för bergavläsning vid fjärrstyrt skrotningsarbete

Mechanical scaling is one of the most complex operations of all in the mining process. The operators are using both hearing, sight and feel to read the rock and to know where to scale and where to leave. They say they go on gut feeling in great extent, something that comes with experience. The scaling machine is placed into the edge of unsecured and newly blasted rock to hammer off the blocks that has become loose after the blast, but not enough to fall down. It goes without sayingthat it is a risky job.

Evaluation of a selective media for the detection of gram-positive bacteria in leg ulcers and pressure wounds

Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens.    The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.

Kunskaper om karies och gingivit hos barni årskurs 3-5 - en enkätstudieKnowledge of caries and gingivitis among third to fifth grade school children

The aim of this study was to investigate the knowledge of caries and gingivitis among third to fifth grade school children. A questionnaire was distributed to 117 children of a primary school in the south of Sweden. The result of the study indicate that the children had good knowledge regarding development and prevention of caries and gingivitis. However, the children did not know the meaning of the words caries and gingivitis. The children also appeared to lack important information about dietary measures to achieve good dental health.

Skolperspektiv på jämställdhet : En studie av grundskollärarens sätt att tala om jämställdhet i relation till flickor och pojkars resultat.

AbstractThe school today has an assignment to offset traditional gender patterns as well as to create opportunities for all pupils to achieve the same good results in school regardless of sex, ethnicity and conditions. The educator?s assignment is determined by governing documents, and the educator plays a role in helping the pupil find their equal role in society. This means that the educator needs to work in a way that offsets traditional gender patterns and require approaches that would benefit equal opportunities for both boys and girls to achieve good results.The purpose of the study was, through interviews, to get an idea of how primary school teachers from a gender equal perspective perceive how they see them relate to boys and girls in their teachings. The study is based on the presumptions that the pupils have but focusing on the relationship between school achievements and equality.The study brings up concepts like gender theories, equality, the biological sexes, the history of the schools development and changes in acceptance of boys and girls and the role of the governing documents to reach acceptable achievements.

Vårdcentralschefers perspektiv på distriktssköterskors förskrivningsrätt

Background: In 1994 came the general prescription law in force for the district nurses with specific training in pharmacology and pathology in Sweden. According to The National Board of Health and Welfare from 2004 follow-up of the use of the prescription law revealed that nearly half of the district nurses used their prescription once a week. According to previous research the district nurses and patients were positive to the district nurses administration of prescriptions. Doctors, contrariwise, were not as favorable to the district nurses administration of prescriptions. The responsibility of the heads of the health centers is to promote the district nurses to prescribe and make sure that it works in a satisfactory manner.

Att beskriva och jämföra en expertgrupp och intensivvårdssjuksköterskors överensstämmelse i att detektera delirium hos intuberade, respiratorbehandlade patienter med sedering/analgesi, före och efter en utbildningsintervention : En kvasiexperimentell stud

The aim: was to describe and compare a group of experts and critical care nurses' agreement in detecting delirium in intubated, ventilator treated patients with sedation / analgesia, before and after an in house training intervention with the instrument Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).Method: A quasi-experimental study, one group pretest - posttest design. A convenience sample of 17 critical care nurses in a general intensive care unit included. To detect delirium the instrument CAM-ICU was used, 21 paired tests before and 22 after an educational intervention.Main Results: The results showed that after an in house training intervention sensitivity and kappa coefficient improved of the characteristic 1 "acute onset and fluctuating course," an improvement that was significant. In other features, and overall values were signs of numerical improvement and deterioration in sensitivity, specificity and kappa coefficient but no significant change.Conclusion: Implementing a new instrument for detecting delirium in clinical practice requires education and follow-up. A small sample of critical care nurses with varying ability to use the new instrument and the fact that patients' status may change rapidly making it difficult to draw any conclusions from this study.

Ytbearbetning av ersättningssten för kulturhistoriska byggnader

The study investigates questions and considerations emerging when stone in historic buildings needs to be replaced. The focus is on the surface treatment of stone in sandstone façades in pre-industrial buildings. That means buildings constructed by traditional methods and craftsmanship without the use of modern technology.The research issue originates from the extensive stonework that is planned for the façades of the Stockholm Palace. The project includes the replacement of large quantities of damaged stone to newly cut stone. This raises the questions about the use of modern and rational methods for surface treatment on the replacement stone.

Under extrem press En kvantitativ studie av hur svensk dagspress förhåller sig till politisk extremism

Authors: Martin Mederyd Hårdh, Frida Nygren, Daniel PaulssonTitle: Under Extreme PressureLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishMethod: Quantitative content analysisPages: 38Politically motivated extremism is a common topic in the Swedish public debate ? and hence in Swedish media. The purpose of our study is to get an idea of how the media relates to the extremist groupings. On a traditional political scale, ranging from left to right, our study focuses on the Swedish extremists who figure on the outskirts of this scale; The ones who denounce the current system and opt for violence to change it.Violence is often an instrument used to get extreme political ideals in the public eye, and is seen as a threat to the Swedish democracy and the public in general. Both sides argue that the Swedish press is tendentious and treat the various extremist groups differently, airing their distrust for the media as a propaganda tool for these groups to establish themselves in the public debate.Our study consists of a quantitative content analysis where we study articles published in print by seven major Swedish newspapers.

Utveckling av analysmodul till Zenicor Medical Systems EKG-system

The mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition..
