Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Syfte: Studera sju portföljer och notera den bästa typen av portfölj med högst avkastning till lägst risk.Metod: Sekundärdata är grunden för uträkning av samtliga portföljers avkastningar, risker och korrelation. Studien är deduktiv med kvantitativa inslag av kända teorier av nobelpristagare i ekonomisk vetenskap. Slutsats: Studien visar att stora bolag i olika branscher är ett vinnande portföljinnehåll för denna studie. Stora bolags aktier har visat högre avkastning till lägre risk jämfört med små bolag under studiens tid då ekonomiska kriser drabbade marknaden. Den mest presterande portföljen var därför storbolagsportföljen.Vidare forskning: Längre tidsperspektiv och nya teorier som Jensens alfa samt Treynorkvot är av intresse för vidare forskning för att styrka vår slutsats..

A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a Correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.

This thesis aims to further study the interpersonal risk taking within groups and thereby the importance of a climate promoting a reflective behavior. The increased demand in complexity and exposure towards teamwork leads to increased call for knowledge integration, which can be explained as the ability to integrate the collective knowledge within the group. We have therefor identified a need for better understanding what makes a group more effective. Key factors for self-estimated effective collaboration have been shown to be a group's reflective behavior and ability to coordinate the skills that each individual possesses. These factors are greatly affected by the psychological safety within the team.

The function of traditional leaders in the modern states of Africa has been under debate for decades. The dominant research discourse suggests that these institutions should be integrated into the state in order to minimize the amount of parallel political spheres, since the latters are considered to affect state legitimacy negatively. But are the states in a situation where they need to compete with the traditional institutions in order to gain more legitimacy? If so, is the struggle for legitimacy a zero-sum game where there can only be one winner? Or is it possible for these institutions to co-exist or even benefit from each other? The aim of this bachelor?s thesis is to research if, and to what extent, African citizens? confidence in traditional institutions has an effect on state legitimacy. This has been done by statistically analyzing the data from the latest completed round of the Afrobarometer survey, a study that has been conducted in 20 different countries across West- and Northeast Africa.

The purpose of this study was to investigate patients self-rated ADL-function after a periprosthetic fracture, to view the demographics of the patient group and investigate any gender differences in ADL-function. Whether patients managed to return to previous housing after the fracture and reasons for this was also studied.This is a register-based retrospective and prospective cohort study with a quantitative approach. Demographic and anamnestic patient data was collected from the electronic health records. The participants were called for an interview where Katz ADL-index and EQ5D was used to describe the participants´ ADL functioning together with physical and mental functioning.The result shows that the majority of the participants rated themselves as independent in their ADL-function. No gender differences were noted in ADL-functioning.

The purpose of this study is to examine whether personality traits, self-esteem, performance-based self-esteem and demographic data relate to, and can explain the variation in psychological ill-health among students at Lund University. A questionnaire was distributed to students attending the Psychology program, Bio-technology program, Theologian program and Law program. There were 247 respondents to the questionnaire, mainly attending their second or third semester. General Health Questionnaire (GHQ-12), Rosenberg's Self- Esteem scale, Hallstens scale measuring performance-based self-esteem, questions relating to demographic data and a short version of the personality inventory scale Big Five were included in the questionnaire. Positive Correlations were found between psychological ill-health and the variables neuroticism and performance-based self-esteem.

Det finns olika teorier som beskriver faktorer föratt skapa organisatoriskt lärande. I denna studie har det undersökts hur faktorer, för lärande organisationer, samvarierar inom två stora, svenska företag. De två företagen har definierat var sitt problem som är relaterade till organisatoriskt lärande. Studien har även undersökt om dessa samvariationer kan användas för att bidra till en lösning på de problem företagen har. Empiri från de två företagen har samlats in genom enkäter och svaren har sedan analyserats med hjälp av analysverktyget IBM SPSS Statistics.

This Master?s thesis is the first to quantitatively study the prevalence of library anxiety at a Swedish university. Library anxiety is a concept describing the negative feelings students can experience when using the library. The study was conducted using web questionnaires sent out to 512 students at Växjö university. 38 % responded and the results were analysed with the help of, amongst other methods, Correlation studies.

The relationship between employer and employee is, from a judicial point of view, governed primarily by economic and employment contracts. However, a significant part of the dynamic is also dictated by tacit expectations and promises (so called psychological contracts). The aim of this study was to investigate the relationship between perceived organizational support (POS) and psychological contract violation. Primary hypothesis assumed that there was a Correlation between higher perceived organizational support and a reduction of feelings of violation from psychological contract breach. It was also assumed that employment time, sex and past breach experiences correlated with feelings of violation.

Although Sweden has democracy implemented in its Constitution, because of being a monarchy, it has a non-elected Head of State. The purpose of this thesis is on the one hand to show if it is possible to normatively legitimate the Swedish monarchy and on the other hand to display if and how the three biggest Swedish newspapers Aftonbladet, Dagens Nyheter and Expressen justify monarchy by making a content-oriented analysis of their coverage of King Carl XVI Gustaf's political statement during his state visit in Brunei 2004.By using consequentialism and deontology as perspectives I will show that it overall is not possible to normatively justify the Swedish monarchy compared to a Swedish republic with an elected Head of State. This is mainly because democracy is implemented in the Swedish Constitution. In all three newspapers there is only little debate on the Constitution. Most commonly journalists criticize the King's statement but not monarchy as an institution.

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

Background: Postoperative infections are a serious patient safety problem and affects about 3 % of all patients undergoing surgery. The consequences are prolonged hospital stays, high social costs, increased use of antibiotics and impaired quality of life for the patient. It has been shown that postoperative infections may be caused by contamination already in the operating room. Today we know that there is growth of microorganisms on the instrument table´s top, but there is a research gap about the instrument table's edges.Aim: To examine if the sterile drape on the instrument table´s edges are sterile after finished surgery.Method: Contact plates are printed on strategically selected areas on the sterile drapes top and edges. In the pilot study, a total of 51 cultures were taken at the end of three operations which lasted over three hours.Results: Growth on the top surface and the edges of the sterile drape were detected.
