Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.

We have in this essay studied the Swedish Hedge Fund Market available for the average Swedish private investor. We have closely looked at the risk measurements that are applicable on the evaluation of Hedge Funds today, and furthermore studied how they are communicated and what they actually contribute with in terms of risk and yield. Our survey attempts to clarify the shortcomings in the communication between the Hedge Fund Managers and their smaller investors. Do they really know where they put their money? The market is rapidly expanding and our goal was to find improved ways to inform about the Hedge Funds risks and opportunities.

The purpose of this paper was to examine the potential presence of a relationship between the quality of corporate financial disclosure and the volatility in stock price in the Swedish market. This was carried out by investigating the hypothesis that an accurate annual report with high information quality results in a decrease in volatility. Previous studies have been done with this approach and in some cases the above stated hypothesis was found to be true. Thus, in the absence of a perfect efficient market the level of information quality may to some extent explain the volatility in stock price. However, the result of our study gave no evidence in support of this hypothesis.

Background: The devolopment in the exchange market has attract a large number of investors. The information flow is extensive and it might be hard to follow the dynamic market. Some investors therefore choose to place their capital in a stock portfolio which is manged by a professional firm with no influence from the capital owner, this management is called discretionary managing. Purpose: the purpose of the thesis is to examine the working methods and the rationality regarding the management of the discretionary portfolios. The purpose is also to try to examine whether there is a relation between the selected risk, return and fees.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

Datainsamling av empirisk primärdata har skett genom semi-strukturerade intervjuer. Teoretisk referensram: Det teoretiska kapitlet tar upp grundläggande teorier kring asymmetrisk information, ?moral hazard?, ?agency costs? och riskhantering.

Inledning Postoperativt illamående och kräkning är ett välkänt problem efter sövning medgenerell anestesi och drabbar mellan 20 % och 30 % av alla patienter som blir sövda. För attminska de obehag och lidande som illamående och kräkning kan ge den postoperativapatienten vore det optimala att profylaktiskt behandla de patienter som löper en stor risk attdrabbas av postoperativt illamående och kräkning. För att avgöra hur hög risk patienten har attdrabbas av postoperativt illamående och kräkning beskrivs i litteraturen ett flertalriskbedömningsmodeller som sjuksköterskan kan använda sig av. Syfte att granska omanvändandet av en riskbedömningsmodell kan minska frekvensen av postoperativt illamåendeoch kräkning hos patienter som erhållit generell anestesi. Metod Litteraturstudie.

The background to this final thesis is that our mandator, A-hus, was interested to examine which roof system that would be most appropriate to their types of houses. To investigate this, we first conducted an evaluation of the most commonly used roof systems in Sweden today: decking, board, roof cloth and prefabricated roof cassettes.To gather information about the different systems we have conducted interviews with several professionals within the construction industry, done an extensive literature study, and gathered information from the Internet.Based on the evaluation of roof systems and the literature, we analyzed advantages and disadvantages of the roof systems from three main perspectives: system characteristics, economics and other characteristics. We found these perspectives to be the most relevant when selecting a roof system.The main perspectives comprise three categories which are graded. These grades are then added together for a score for each main perspective and a total score for the three main perspectives. Then we compared the systems and, based on the scores, suggested one roof system as the most suitable for A-hus.Our result suggests that the prefabricated roof cassettes probably is the best solution for A-hus, but only if it is possible to standardize the cassettes and still maintain the flexibility to match A-hus? house types.

SammanfattningDet har tidigare visats att överviktiga patienter riskerar att bli förbisedda i screening för undernäring och att vårdpersonal har negativa uppfattningar om överviktiga individer. Det har även visats att överviktiga själva upplever att de behandlas sämre än andra. Men trots hög förekomst av undernäring bland sjukhusvårdade patienter har få studier utforskat om patienter med risk för undernäring får olika vårdinsatser beroende på deras BMI. Således är syftet med denna uppsats att undersöka om vårdinsatser vid identifierad risk för undernäring i någon utsträckning är beroende av patientens BMI.Datamaterialet kommer från en retrospektiv tvärsnittsstudie baserad på genomgång av 56 journaler för vuxna patienter med risk för undernäring, inlagda på somatisk vårdavdelning på tre svenska sjukhus. Denna studie undersöker möjliga skillnader beroende på patients BMI för förekomsten av 1) bedömning av mun och sväljförmåga, 2) kostregistrering, 3) dietistkonsultation, samt 4) kostanpassning.I detta begränsade urval finns inga sådana skillnader som uppfyller kraven på statistisk signifikans, men analysen påvisar några tendenser i datamaterialet som antyder att patienter kanske behandlas olika med avseende på BMI.

The purposes of this study were to estimate genetic and phenotypic parameters for conformation traits in Swedish Ardenner, a heavy draught horse, and to investigate the inbreeding status of the population. Additionally, a breeding scheme proposal was created, based on the results achieved in the study. The data studied were obtained from the Swedish Horse Board and from the Swedish Ardenner Association. The data included 1632 three-year-old horses, mainly mares, and 356 stallions, judged between 1986 and 2005 at conformation shows. The traits studied were type, head-neck-body, legs, walk and trot at hand, total score and height at withers.

Background: A company?s choice of capital structure is influenced by the access to internal and external capital but also by the opportunities and threats that the management perceives in the environment and the management?s attitude towards risk. How an individual perceives and interpret the environment depends on the cognitive structures, which are shaped by personality, background and earlier experiences. Accordingly cognitive structures can be expected to influence the choice of capital structure. Purpose: Out of a cognitive perspective we intend to study the relationship between the way a company views it?s environment and what capital structure it chooses to have, in order to contribute to an increased understanding about what lies behind a company?s capital structure policy.

Abstract  The development and onset of diseases such as cardiovascular disease (CVD) and Type 2 diabetes are closely linked to genetics and lifestyle factors including physical activity and diet. A cluster of metabolic disorders called the metabolic syndrome (MetS) is a high-risk factor in developing these diseases. Acording to the International diabetes institute, one fourth of the worlds adult population has MetS. These individuals are twice as likely to die from CVDs compared to individuals without MetS. Physical activity (PA) and exercise has been shown to provide a number of positive effects that are considered to reduce the risk of developing sickness and premature mortality among both men and women of all ages, independent of other risk factors.

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.
