Giardia är en protozo, ett encelligt urdjur. Parasiten har en direkt livscykel med fekal-oral spridning. Få cystor krävs för att ge upphov till sjukdom och cystorna är mycket resistenta i miljön. Giardia delas in i 6 arter varav Giardia duodenalis (syn. G.

The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.

About a quarter of the Swedish land area is covered with shallow or thick peat. There is a potential to increase forest production in Sweden with almost 2 million m3/year in selected peatlands with low conservation values. This increase can be accomplished by drainage, complementary drainage, ditch maintenance operations and fertilization. The purpose of this study was to determine the level of knowledge regarding the management of forests on peatlands and was restricted to selected forest companies in Västerbotten County, with offices in Umeå. Three companies were chosen, SCA, Holmen and Norra Skogsägarna.

The purpose of this thesis is to make a comparative literary study of ten laboratory experiments with different kind of sources for query expansion terms. The experiments are grouped according to categories of term sources, which are: search results, collection dependent knowledge structures, collection independent knowledge structures and one that combines the two last mentioned sources into one. To enable a comparison all other variables were held as constant as possible. There is the improvement measured in mean average precision, which is used to measure the various sources potential. The result from the study shows a strong connection between the kind of source for the expansion term and improvement of the result.

Hylocomium splendens (Glittering wood-moss) is a common species in the Nordic countries and can be found in many different types of boreal forests. It usually forms dense moss carpets on the forest floor. The shoots grow in segments and new segments form annually on the previous years growth. The size of the segments is probably regulated in a high extent by local micro environmental conditions. Previous experiments suggest increased growth of H.

At SLU, Divison of Reproduction, Dept of Clinical Science, there is an ongoing project on the development and evaluation of new methods for the assessment of stallion semen quality. This EEF-study, which is a part of that larger project, has focused on the effects on motility and fertility of stallion semen of two different extenders and selection. Both an objective method and a subjective method for analysis have been used and compared in the study. The increase in the use of artificial insemination with cooled semen in Swedish horse breeding over the last decade is thought to play a part in declining foaling rates (Kareskoski et al, 2006, Kuisma et al, 2006). This calls for better evaluation methods of semen quality since cooling and transportation put higher demands on semen quality in order to maintain fertility (Aurich, 2005).

This paper aims to describe and elaborate on a recent discursive change within the new-age movement. Since the seventies and the publishing of speculative popular science books like The Tao of Physics by Fritjof Capra and The self-aware Universe by Amit Goswami, the idea that quantum physics resonates with spirituality has become the topic of hundreds of books and movies.The quantum-spiritual discourse has three distinct ways to approach quantum physics in its discussion on spirituality: The parallelistic approach which emphasizes the similarities between eastern philosophies and modern physics, the monistic-idealistic approach which tells us that mind is the foundation of matter and the scientific spiritual approach which tries to explain spiritual claims scientifically. In the quantum-spiritual discourse, quantum physical phenomena (e.g. non-locality and entanglement) are being called upon to validate metaphysical statements. The primary assumption of the discourse is that the shift of paradigm due to the establishment of modern physics also is a shift of paradigm of spirituality.With the object to examine the common claims made in the discourse, cross-references between spiritual arguments and facts of quantum physics are being made.

This essay is about democracy and how a democracy index can be used as a tool to illustratethe gap between reality and ideal. The purpose of this study can be expressed by two researchquestions: Does the Economist Intelligence Unit's (EIU) democracy index illustrate thedistance between reality and the ideal of democracy presented by Dahl? and Can the EIU'sdemocracy index be modified by a) internal adjustments and b) using the variables includedin World Economic Forum?s (WEF) equality index?By using a combination of theories (Dahl?s theory of democracy, Rawls theory of justice andchosen theories critical to liberal democracy) as an analytical framework the following twoquestions have been answered:1) Which of the variables included in the EIU's democracy index have the potential to capturethe level of political equality?2) Which of the variables included in the WEF?s equality index have the potential to capturethe degree of political equality?By using a quantitative method the study?s third and last question has been answered:3) How strong is the rank correlation between the EIU?s democracy index and the WEF?sequality index, that is; how strong is the rank correlation coefficient (rho)?The data presented by the WEF?s equality index indicate that women are systematicallydiscriminated against as a group. From a democratic perspective the EIU may need tomeasure inequalities at a group level in order to capture the lack of political equality betweenindividuals. By reformulating some of the EIU?s variables, by revising the EIU?s point systemand by using the variables included in the WEF's equality index to extend EIU?s democracyindex, the chances of capturing the gap between reality and the ideal of democracy presentedby Dahl would likely increase..

En omfattande miljöpåverkan till följd av användandet av fossila bränslen har letttill ett behov av alternativa energikällor som inte bidrar till en ökad växthuseffekt.Biogas har potential att produceras som ett koldioxidneutralt bränsle. Det energibesparande ämnet i biogas är metan och kandidatarbetets syfte är att framställametan under katalytiska processer.Metan kan skapas genom den sa kallade Sabatier-reaktionen där koldioxid ochvätgas reagerar till just metan och biprodukten vatten. Denna reaktion har studeratsur ett praktiskt, miljömässigt och ekonomiskt perspektiv. En Sabatier-reaktori laborativ skala har designats och konstruerats. Flertalet försök har gjorts för attutvärdera effekten av olika parametrar såsom temperatur, volymsflöde och gassammansättning.

The feed is a major cost in the dairy production and there is a constant interest in findingalternative cost-effective feedstuffs. Competitive dairy producers have to seek ways todecrease their production costs and the pursuit of cost-effective feed rations contributesto lower costs of production. An interesting group of protein concentrates are rapeseedproducts like ExPro (heat treated rapeseed) which have during the autumn 2008 andspring 2009 been very favourable compared to other protein feeds.This study focuses on the feedstuff products ExPro and Raps-Drank 60/40 (rapeseeddistillersgrain). The potential use of ExPro in dairy cow feed rations are also explored.ExPro is a well known feedstuff but Raps-Drank 60/40 is a relatively new product andnot known for many farmers.A field study on the use of rapeseed products was made on a limited number of dairyfarms. The main purpose was to study the management of the feedstuffs on the farms.The Farms were selected in cooperation with two local extension services.

The gender theory of Judith Butler is based on both philosophical and psychoanalytic notions of the self. Although greatly inspired by both early and contemporary psychoanalytic thinking, Butler has also questioned some of its core notions such as the meaning of gender complementarity and conceptions of desire. In a dialogue in Studies in Gender and Sexuality she discusses these and other theoretical and ethical issues with the influential psychoanalyst and gender theorist Jessica Benjamin. The exchange is a unique example of an attempt at dialogue and theoretical reflection between a prominent contemporary gender theorist and psychoanalyst. It reveals disagreements and theoretical difficulties I will show to be directly attributable to radical differences between Butler's and Benjamin's conceptions of the self.

African Swine Fever (ASF) is one of the most serious transboundary swine diseases because of its high lethality for pigs, socioeconomic consequences, rapid and international spread and the absence of either treatment or vaccine. This Sida Minor Field Study (MFS) was carried out during fall 2010, as part of a larger collaborative research project called ASFUganda, focusing on the epidemiology of the disease in Uganda. The aim with this study was to get more knowledge about the pathology in cases of ASF in Uganda, by studying macroscopic and microscopic lesions in pigs with acute and chronic ASF and to detect the ASF virus (ASFV) in tissues by immunohistochemistry. The pigs were selected from the two different geographical locations in Uganda, Mityana and Gulu district, both with on going confirmed outbreaks of ASF. Necropsies were performed in the field, and the laboratory procedures at the JICA (Japan International Cooperation Agency) Veterinary Pathology Laboratory, Entebbe, Uganda, and at the Department of BVF, SLU, Uppsala, Sweden. Three pigs from an outbreak of ASF in Mityana district showed both the history and the clinical symptoms typical for ASF.

This study departs from the observation that since the late 1980´s educational programmes for curators have been established and since then expanded greatly. The programmes are part of a process of institutionalization and professionalization of the role of the curator within the international contemporary art field where the role as such has gained much power. Even though many statements have been made about this relatively new phenomenon of curatorial studies, there is a lack of sufficient research. The intention of this study is therefore to examine the educational programmes as such. The selection of 15 programmes has been made with the purpose to include early as well as newly established and to cover a wide geographic area.
