With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

Syftet med undersökningen är att genom en jämförande modellstudie ta fram ett eller flera sätt att nedkämpa en motståndare utrustad med tungt reaktivt pansar. Reaktivt pansar har tidigare endast använts för att hindra RSV-strålar att penetrera pansar. Men teknikutvecklingen har nu medfört att dagens reaktiva pansar utöver skydd mot RSV-strålar också klarar av att reducera pilprojektilens förmåga till penetration. Amerikanarna som tidigt upptäckte att Ryssland hade tillgång till tekniken började direkt utveckla ny ammunition för att möta detta. Men vad har vi gjort i Sverige, sen detta uppdagades? Kan vår Stridsvagn 122 fortfarande lösa sin huvuduppgift: att slå ut andra stridsvagnar?I studien gör författaren antagandet att spårljuspansarprojektil 95 inte får genomslag på en stridsvagn utrustad med tungt reaktivt pansar, typ Kontakt-5.

Based on laboratory studies with lysimeters, the concentrations of dissolved Reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.

In studies of serum, in the early 1930s, from patients with pneumonia, a factor was found. It could agglutinate certain pneumococcal species. This factor, which later became known as C-Reactive protein (CRP), increased sharply during the early and middle stages of the disease. CRP was identified as an acute phase protein and found especially in bacterial infections. CRP is synthesized in the liver by stimulation of interleukin 6 (IL-6), which is produced by the monocytes, and consists of five non-covalently bound subunits.The aim of this study was to compare two different analytical instruments (Vitros 5.1 FS Ortho-Clinical Diagnostics and QuikRead CRP Orion Diagnostica) for CRP analysis.

Förgiftningar hos däggdjur som druckit vatten kontaminerat med cyanotoxiner har observerats världen över, och riskerar att öka i takt med tilltagande övergödning och klimatförändringar. Denna litteraturstudie inriktar sig på mikrocystin (MC) som är det vanligaste och mest studerade cyanotoxinet. Studien avgränsar sig till akut intoxikation hos däggdjur och fokuserar på grundläggande mekanismer hos toxinet, såsom absorption, distribution, metabolism och elimination. Vidare beskrivs de toxiska mekanismerna och de akuta toxiska effekterna. MC orsakar utbredda nekroser och blödningar i levern. Den specifika distributionen till levern anses bero på det höga uttrycket av organiska anjontransportörer (OATP).

When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.

In this two years master's thesis a regional project, Futurum.kom, is studied through the experiences of eight librarians from two of the participating libraries. The interviewees have all attended local and regional seminars where questions about core values, target groups and the role of the public library were discussed, among others. The seminars resulted in a number of core values and target groups. During the project, a number of advertising campaigns are to be conducted. The first one of these had recently been implemented at the time of the present study. The aim of the thesis is to investigate the interviewees organizational self-perception in relation to the project.

Bakgrund: Gingivit kännetecknas av svullet/lättblödande och ibland ömt tandkött. Gingivit är en inflammatoriskt orsakad reaktion som uppkommer i samband med närvaro av bakterier. För att motverka utvecklingen av gingivit rekommenderas munhygienvård regelbundet. Gingivit kan utvecklas till parodontit med skador på upphängningsapparaten och benstödet, orsaken till detta är idag dock ej helt klarlagd. Kliniska variabler (blödning vid sondering) är vedertagna diagnostiska metoderna för diagnostisk av gingivit idag.

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

The term CSR (Corporate Social Responsibility) is frequently discussed today. Many large companies work actively with CSR related questions. However, few empirical studies exist on what this work entails and why it is undertaken. Instead, most of the academic research focuses on what the term itself should mean. To bridge this gap this study centers on the employees? perceptions of CSR.

This essay compares the public debate in Sweden 1992 caused by the reforms introduced by the then government giving parents a free choice of schools for their children with the current debate in France about proposals for a similar law there. The study concentrates on the positions taken by the teachers trade unions, in Sweden Lärarförbundet and Lärarnas Riksförbund (LR) and in France SGEN-CFDT. To do so it is necessary also to study the arguments given for and against the proposals by the political parties.Some of the differences between the debates can be attributed to different circumstances. The Swedish reform was related to the opening up of possibilities to run private schools, which previously had been rare in Sweden. The French debate has no such connections.

The voltage level in the power grid varies due to variations in load and production. Normally these variations are manageable, but they may be excessively large during a disturbance. If the voltage is too high it may damage the equipment in the grid and too low voltages may cause problems like voltage instability. The magnitude of the voltage variation depends on the short circuit power capacity of the point of interest.This problem may become lore prominent due to automatic voltage regulation that acts on shunt reactors and shunt capacitors. When the shunt reactor is connected or disconnected to the grid it may cause such large changes in the voltage that the shunt reactor starts hunting.

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

The perspective on health among school pupils needs to be extended. School is animportant arena for the promoting of health among youth, primarily from a healthpromoting perspective and a proactive perspective. A holistic approach has gatheredsome ground in the policy documents for the nine year compulsory school in Sweden, butin what way, and what effect does it have on the governing authorities and on schoollevel?The aim of the study is to investigate the coherence between national, municipal andlocal levels regarding the view on health among pupils. In order to do this, the guidelinesfor pupil health in the municipality of Örebro and operational plans for seven F9 schoolsin the municipality of Örebro will be studied and compared to the government bill?Health, learning and sense of security?.
