The acid deposition of sulphur- and nitrogenoxides from combustion of coal and oil cause acidification that lowers pH and gives increased contents of metals and altered aquatic biodiversity in the stream. The liming of lakes and streams, which was introduced to resist the acidification, demand large economic resourses despite of the decreased deposition of the acidifyng substances. Some of the streams are influenced by the acid deposition, while others are naturally acidic. It is therefore importaint to separate the anthropogenically acidified waters from the naturally acidic, in order to optimize the use of governmental fundings for liming. This thesis aims to estimate the acidity status and impact of acidification on 24 catchments upstream liming dispensers, which is part of the liming activities at the County of Dalarna.The acidity status of the streams was classified according to the Swedish Environmental Protection Agency old classification system (Naturvårdsverket 1999) as very acid to acid, with small ability to withstand a pH-change (alkalinity) due to acid deposition.

Bakgrund: Alzheimers sjukdom är den tredje vanligaste dödsorsaken i västvärlden idag. Det är en progressiv sjukdom som drabbar hjärnan och därmed påverkar personens kognitiva förmågor. De alzheimersdrabbade blir ofta vårdade i hemmet av sina anhöriga, vilket kan innebära en stor påfrestning för dessa. För att vårdpersonal skall kunna stödja de anhöriga på bästa sätt krävs en förståelse för hur de upplever sin situation. Syfte: Syftet var att belysa anhörigas upplevelser av att leva tillsammans med en person med Alzheimers sjukdom.

This two years master's thesis in Library and Information science, examines how the implementation of new technical equipment can affect how staff in public libraries organize their work and activities in the library. One Swedish public library in specific is the subject of research in this thesis, which has been anonymized as Kvarntuna city library. The study takes place in the beginning of the implementation of RFID-technology in the library. RFID, which stands for Radio Frequency Identification, is supposed to make the handling with different types of media in the library more efficient and in connection with the implementation one wants to reorganize work and activities in the library to make it even more efficient and also create a modern library.The thesis' method is qualitative interviews with six members of the staff. The theoretical framework of the thesis is a sociocultural perspective, especially inspiered by Roger Säljö, a Swedish professor in pedagogical psychology.

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

The target group of the study was employees (eleven), their managers (seven) as well as co-ordinators (two) of a maintenance department at a nuclear power plant. The training program lasted from December 2009 to May 2010. The study was in progress as of September 2009 when a decision was made at the maintenance department?s training board to carry out the evaluation.

The insurance industryis challengedby major changesthrough internationalizationand thusgrowingcompetitionwithmore optionsand greater availabilityfor customers.Solvency II, a new regulatoryframework and anew standard forinsurance companies,is therefore implemented in a steptowardsa more competitive Europeaninsurancemarket. Solvency II will result in extensive structural changes for many insurance companies. Newstandards andinternal models must also be implemented by the companies. Solvency IIhasa tightening effect on thesolvency capital requirements forinsurance companies. At the same time it also leads tomajor changesandincreased demandon risk management andinternal control, alongside with demands fordisclosure of informationto the market.

Time of harvest affects nutritional value and digestibility of haylage since plants are in different developmental stages. The aim of this study was to examine the effect of plant maturity of haylage cut in June, July and August on digestibility and faecal particle size in horses.Forage and faecal samples used for the analysis of apparent dry matter digestibility (DMd) and particle size distribution in faeces were from a feed-study performed in the autumn of 2009. Twelve horses were used in the study, divided into three groups in a change-over experiment. Each group was fed haylage harvested in June, July or August during three periods. Faecal grab samples were taken from each horse and pooled so that one sample represented one horse during one period.

This master?s paper first presents some of the principal theories and concepts developed by the poverty researchers Rowntree, Titmuss, Townsend, Sen and Lister. These theoretical frameworks are then related to two documents from the EU and Sweden concerning combating poverty and social exclusion, bearing on the establishment of the ?Year 2010 against Poverty?. Finally, I discuss the value in practice of these theories and policy documents, as regards reducing poverty in Europe.It has become clear in this investigation that the theories and concepts from earlier research are still relevant to the formulation of contemporary policy programmes, and that earlier research helps us to avoid old traps in fighting poverty.

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.

Den här studien gjordes för att undersöka om lärare uppfattar ett samband mellan elevers koncentrationsförmåga och fysisk aktivitet i skolan. Den baseras på en enkätundersökning som gjorts i årskurserna 1-5 på sju olika skolor i närområdet. Studien visar ett positivt samband mellan all fysisk aktivitet i skolan och lärarnas uppfattning av elevernas koncentrationsförmåga, vilket även kopplats samman med tidigare forskning inom närliggande områden. Nyckelord: physical education AND concentration, physcial activity AND concentration ability, physcial acitivty AND effect in school, excercise AND brain, physical education AND brain..

The effect of moderate incongruency between a celebrity endorser and an advertised brand is considered in an experiment with celebrities, both congruent and moderately incongruent with the investigated brands. In addition, the influence of possible moderator variables was examined, as well as the potential impact of the celebrities? gender. It was found that an ad exposing a moderately incongruent combination of celebrity and brand generated a more positive result on attitude towards the ad, brand attitude and word of mouth. Furthermore, under some conditions certain moderator variables influenced the relationship between moderate incongruency and responses evoked by the ad..

The purpose of this Bachelor?s thesis is twofold. Firstly it aims to make a contribution to the understanding of how five Swedish Diocesan libraries have carried out the digitizing of their rare book and manuscript collections. Problem areas related to this activity are also investigated. Secondly, it aims to examine the relative guidelines and standardization norms, which have been formulated on a national basis.

This thesis examines the relationship between the marginalization of ornamentation during functionalist modernism and the effect it had on female graphic design practice. By examining the historiography from a gender and feminist theory of history I present a different way of interpreting, not only the history of graphic design but also the concept of graphic design. This thesis does not reach a conclusive result, instead it sets the foundation for further research and illustrates the opportunities that we as graphic designers have to benefit contemporary graphic design by critically reviewing and redefining our history through a diverse historiography..

The aim of this thesis is to examine the Swedish model with attention to core values over time, as well as, explain recent changes. It examines changes of the social insurance system, with focus on political reforms in the unemployment insurance, health insurance and family policy, during the last two decades. The thesis is empirical but although a discourse amount political theories and normative conceptions.Conclusions are that the normative basis in the Swedish model contains general equally and uni-versally designed rights and consensus on growth and development as well as a strict focus on an employment oriented society. Important values have also been dialogue between actors as well as accountability, even if these facts appear to have declined in recent years.Relating to three leading theories in political philosophy - utilitarianism, Rawlsian communitarian-ism - explores the directions in later year political reforms. The results show that later years changes seem to go in relative strongly utilitarian direction.
