Beslut om investering i alternativ energi : en studie om hur lantbrukare fattar beslut vid investering i halmpanna

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

Itrakonazol till häst : en farmakokinetisk möjlighet?

Itraconazole is a third generation azol, a fungicide which acts by inhibiting ergerosterol synthesis in the fungal cell membrane, and thereby disturbing fungal regeneration. It has proven to be less toxic, to have a broader spectrum of activity and to be more potent than its predecessor ketoconazole. Itraconazole is only available in therapheutics approved for human use. Pharmacokinetic studies has been performed in humans, dogs, cats and laboratory animals. Although itraconazole has been used tentatively with good effect against fungal infections in horses, no pharmacokinetic studies have yet been done.

Implementering av en PSS i Trängslets kraftstation

The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

En studie om elevers självkänsla : Elevers utsagor om uppmuntran och stöd i en sjätteklass

 Abstract Study: Degree project in teacher education, Advanced level, 15hpUniversity of SkövdeTitle: A study on students' self-esteem Students' statements on the encouragement and support in a sixth gradeNumber of pages: 26 pagesAuthor: Marie Agapuu & Ingrid SvenssonTutor: Anna-Stina AhlrikDate: January 2009 Keywords: Self-esteem, encouragement, support  A good self-esteem of students will often coincide with good academic performance, but it has also shown that students do not have low self-esteem due to low academic performance. Students' self-esteem is both a complex topic and concepts. We want this study to draw attention and to discuss teachers' efforts to enhance students' self-esteem in school. Encouragement and support of the school adopted in the study contribute to strengthening students' self-esteem. The study examines whether and how nine pupils in a sixth class is that they get encouragement and support of / from their teachers in school subjects and in learning situations.

MEMS baserad referensoscillator

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.

Känsla av sammanhang : En studie kring äldre ensamboendes välmående

ABSTRACT Introduction: This study is based on Aantonovskys SOC-theory; Sense of Coherence. SOC can be described as a theory which describes how a person experience her existence and the theory is based on three key expressions; comprehensibility, manageability and meaningfulness. Aim: The aim of the study is to examine a group of elderly (>80 years) men and women who live alone to investigate how many percent of the group that estimate a high value of SOC. The study aims to investigate which factors contribute to the fact that a person achieve a high value of SOC and increase the understanding about how these factors concretely can appear in a persons life. Methods: Questionnaire (SOC scale) and Interviews.

Business Intelligence i SharePoint

The goal for this thesis work was to develop Business Intelligence (BI) for an IT consultant company.LexiConsult is an IT consultant company in the Lexicon-group which offers expertise within Office (templates, database, spreadsheets, Outlook etc.) but also SharePoint development and services like support, documentation etcetera.We have investigated the functionality in SharePoint and MS SQL Server and have also evaluated which possibilities these platforms offer in terms of creating a BI-solution for LexiConsults needs. SharePoint offers a variety of different tools and services for BI but none of these where available in the Office365-version which LexiConsult uses. Another solution was therefore suggested where the reports should be published on a web hosting company.We have also studied critical success factors when implementing BI in an IT consulting company.The result is a set of BI-reports developed for SQL Server Reporting Services (SSRS), which the staff of LexiConsult can access via their SharePoint site.The reports are designed for monitoring and analysis of the economy with e.g. key performance indicators, drill-down of the revenue in different aspects such as by time period, per employee, per customer etcetera. The reports provides vital knowledge that can be used for decision support, e.g.

Ekonomisk frihet och nationers välstånd

This bachelor thesis examines the relation between countries? degree of economic freedom and their economic performance. Economic freedom as a concept is defined as the degree of market economy within a nation.The variable of measure that is used is the Frasier institute Economic freedom of the world index (EFI). The paper is built upon the Solow growth model and is extended by incorporation of additional variables; among which of course economic freedom. The study is performed through regression analysis, based on the neoclassical model both on rich countries, poor countries and on all investigated countries.Two investigations are performed: i) the impact from economic freedom on countries level of GDP per capita and ii) the impact from economic freedom on the growth rate in GDP per capita.The finding is that economic freedom can be seen as a relevant determinant of differences in GDP per capita growth rates between nations.

Optimization of immunoassay parameters in multiplex in the high throughput protein detection technique Proximity Extension Assay

The ability to detect protein-based biomarkers, which are linked to different diseases like colorectal cancer, is very important as a diagnostic tool. Usually complex biological samples like blood are studied which will contribute to different technical issues when performing an assay. The aim with the project is to optimize and develop the high throughput protein detection technique Proximity Extension Assay, PEA, into a 96-plex panel, in hopes of discovering an expression profile for colorectal cancer. PEA was developed by Olink Bioscience and allows specific proteins in a sample to be quantitatively transformed into nucleic acid sequences that are subsequently detected and quantified with real-time PCR. Two proximity probes containing oligonucleotide sequences bind pairwise to target protein and when brought in proximity, a DNA polymerase will extend a hybridization arm from one probe over to the second forming a double-stranded DNA sequence that can serve as a template in real-time PCR.
