Population and management models for the Swedish wild boar (Sus scrofa)

The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.

En komplex historia : Elevers övergång från grundskola till gymnsium inom det samtida skolväsendet

Being a student in the educational system is in itself a challenging exercise, considering the various parts that may matter in different extent for the students. There is a syllabus, there are different backgrounds and contexts for each student and there is also the knowledge in the subject to consider. This study sets out to explore to which extent teachers and students reflect about the transition from public school to upper secondary school/high school, specifically in the context of History as subject. What do they think about it and how do they work with it?By interviewing five teachers and letting 94 students in upper secondary school completing a survey about this subject (the transition), I can conclude that the matter is complex, both for students and teachers, however still a significant and important issue to discuss.

Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.

Övergången från SAB till Dewey i forskningsbibliotekssverige: En organisationsförändring ur de anställdas perspektiv

In November 2008 the National Library of Sweden decidedto switch classification system from SAB to Dewey decimalclassification. SAB had then been the main classificationsystem in the whole of the Swedish library field for 87 years.Included into the decision was not just the nationalbibliography but also the research libraries of Sweden. Thisdecision was in alignment with a West European tendency tochange in favor of the internationally well-spreadclassification system Dewey in order to co-operate more inthe cataloguing process. The purpose of this study takenplace in the autumn and winter of 2013 is to examine howlibrarians involved in the transition feel about what differentways the implementation has affected the research libraryorganizations. We also aim to study the librarians? view onthe involvement of the research libraries into the decision ofthe changeover.

Islandshästar med hosta och/eller prestationsnedsättning : skiljer de sig åt jämfört med andra raser?

The purpose of the study was to investigate whether or not Icelandic horses are less severely affected in clinical symptoms of cough or decreased performance than other breeds of horses. A breed variation in chronic respiratory disease severity was suspected based on clinical experience at the Institution for surgery & medicine, large animal, SLU Uppsala. A retrospective journal study of 17 Icelandic horses and 17 Swedish Standardbred horses with chronic problems with cough and/or decreased performance compared several measurements of disease severity. The clinical signs, physical examination and laboratory testing results compared were respiratory rate, abdominal breathing, lung auscultation, endoscopy results, broncho-alveolar lavage (BAL) results and the blood gases pO2 and pCO2. All parameters were available for all 34 individuals except for the blood gases, which were analysed, in only four Icelandic horses and four Swedish Standardbred horses. The only parameters that appeared different between the two groups were respiratory rate and pO2. The four Icelandic horses, which had blood gases analysed, had more severe hypoxemia.

I en värld av makroekonomisk osäkerhet - En scenarioanalys kring ränte- och inflationsförändringars inverkan på ett fastighetsbolags fria kassaflöde

Title: Valuing Real Estate FCFE and interest coverage under macroeconomic uncertainty with scenario analysisAuthors: Marcus Ewerstrand, Jakob MattssonAdvisor: Gert SandahlBackground and problem: After the collapse in the Swedish economy in the beginning of the 1990-ties, the company Secerum was launched. Securums objective was to handle unsecured credits from Nordbanken by transferring a large portfolio of properties and to setup a number of companies who would be in charge for the prospects of these assets. One company that was established during this remarkable period was Castellum, in the year of 1994. After a successful process of raising capital to its development of corporate strategies and formation of several affiliated companies which operates locally, Castellum was publish on the Stockholm stock exchange 1997/1998. Now, thirteen years later after its establishment, the credit crunch in the US.

Vad gör Danmark som inte Sverige gör? ? En komparativ studie av arbetslöshet, investeringar och arbetsmarknadsinstitutioner i Sverige och Danmark (1976-2005).

The aim of this investigation is to explain present and historical differences in the Swedish and Danish unemployment rates between 1976 and 2005 with a broad framework, making use of neoclassical and post-keynesian economic theory. The influence of the rate of investment to GDP, and various institutional factors are assessed in quantitative analysis. It is suggested that the crude answer of the question asked in the title, ?What is it that Denmark does that Sweden does not??, is that Denmark invests. This investigation suggests accordingly that the main reason of the relative labour market success during the 90?s in Denmark was a rising, and rapidly recovering, rate of investment to GDP, and perhaps not primarily its flexible labour market institutions.

Dimensionering av grundläggning med hjälp av Eurokod

AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards  between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes.  The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.

Karaktärisering av hårdmetallpulvrets råvaror och dess påverkan på pulvrets flödesegenskaper

This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.

Hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiskt mått på mental stress hos hästar

SAMMANFATTNING Denna litteraturstudie syftar till att utvärdera hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiska mått på mental stress hos häst. För att utvärdera detta har olika artiklar studerats. Artiklarna redovisar studier där hästar utsätts för framför allt mentala stressmoment. Under stressmomenten har antingen hjärtfrekvens (HR) eller hjärtfrekvens och hjärtfrekvensvariabilitet (HRV) registrerats. Hjärtfrekvensvariabiliteten kan omvandlas till ett antal parametrar, bland annat lågfrekvensband (LF) och högfrekvensband (HF).

Återvinning av dryckeskartonger : En studie som syftar till att öka återvinningsgraden av Tetra Paks förpackningar i Indonesien

People of the modern world consume more than they ever used to do. Because of the close correlation between consumption and the amount of waste, the waste volume is also expected to increase. The purpose of this study is to examine if some measures in the recycling process from Sweden could be implemented in Indonesia. In fact, Indonesia is one of the countries in which the waste management system is struggling. Tetra Pak, one of the world leading producer of food packaging, is studied in this report.

Sociala medier inom klimatrörelsen : hur moderna sociala rörelser använder internet för kommunikation

De senaste åren har sociala medier fått allt större betydelse i människors liv. Det diskuteras om det till och med har varit en del av förutsättningarna för omvälvande sociala förändringar i olika länder. Det mesta av det som skrivits om sociala medier och hur de används rör dock vinstdrivande företag eller uppseendeväckande protester. Mycket lite har skrivits om hur ideella organisationer och sociala rörelser med en mer låg profil använder dem. Detta examensarbete syftar därför till att undersöka hur moderna sociala rörelser använder sociala medier i sitt arbete.

Dygnsvariation av metanemission från en anlagd våtmark

The aim of the study was to investigate if methane emission in a constructed wetland changed in a diurnal pattern correlating to temperature, humidity or light conditions. The gas measurements were carried out with a static chamber technique. The wetland (in Nykvarn outside of Linköping, Sweden) takes care of wastewater to reduce the nitrogen loads. Measurements were carried out at three different occasions in the summer of 1998 on two sites in the wetland. One site was close to the inflow, inhabited by Lemnaceae, and another site was located further downstream inhabited by the emergent macrophyte Typha latifolia.
