Occurence of mould and mycotoxins in Swedish maize silage - a pilot study
During the last ten years the cultivation of maize in Sweden has increased and is expected to grow further. Most of the maize in Sweden becomes silage which is used to feed animals at farms. Maize has in other countries been shown to be a substrate for growth of mould and especially Aspergillus spp., Fusarium spp. and Pencillium spp. has been reported.
Pedagogens perspektiv på målsman : En kvalitativ studie av två förskoleverksamheters syn på samarbetets betydelse mellan förskola och hem
Preschools are nowadays a big part of almost every childhood in Swedish society and the relationships that are built there are important for the child and the child?s future integration in the world of knowledge and education. The preschool teachers are therefore the first persons the child links to beyond the parent. That?s why the relations between the parent and the preschool teacher are an important and interesting aspect in the cooperation between them.
Vedrötor i stadsträd : biologi, detektionsmetoder och förebyggande åtgärder
Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.
Polyfarmaci hos äldre : ? ett världsomfattande hälsoproblem
Antalet äldre har ökat i hela världen och fortsätter att öka. I takt med stigande ålder ökar risken för sjukdomar och därmed även läkemedelsanvändningen. Personer över 80 år konsumerar i genomsnitt 5,8 läkemedel per person och äldre på sjukhem tio läkemedel per person vilket är en ökning med 60 % sedan slutet av 1980-talet. Anledningen till denna ökning är att det idag finns stora möjligheter att förebygga och behandla många sjukdomar eftersom det hela tiden utvecklas nya läkemedel och behandlingsmetoder. Polyfarmaci och olämplig förskrivning av läkemedel till äldre över 65 år enligt Beers kriterier (se bilaga I) är ett växande och världsomspännande hälsoproblem.
Chefen som normsändare : En kvalitativ studie ur chefs - och personalperspektiv
The aim of our study is to explore which norms that exists in the home care service, who is sending those norms, how are they maintained and how do they affect the interactions between staff and manager? We want to deep en our knowledge about home care service as an organization and increase our understanding for the psychosocial work environment and also the importance of leadership. We mean to read the organizational culture that exists which allows us to deal with the values that influence the behavior in the organization.The study is based on a qualitative method. The data consists of two focus group interviews, one with managers from the home care service - organization and one with staff from the same organization. T he interview with the managers consisted of five participants and the corresponding figure for the second interview with the staff was eight participants.The theoretical viewpoints have been communication - theory, organizational theory and Foucault´s th eory of power.Our result indicate that norms are something that unconsciously controls us and that we have learned that there are consequences when you step out of what is normative for the group.
Holy cows and dirty dogs : the influence of culture and religion on animal welfare in India
India is home to every sixth person in the world, some 30 million dogs and a quarter of the total world cattle population. A vast majority of Indians are Hindus, and even though the Hindu religion proclaims love, nurturing and worshipping of animals, sometimes the same religion constitutes an obstacle for animal welfare in practice. This paper investigates the significance of historic and religious symbols to the way animals are perceived in modern Indian society, as well as the different social factors which underlie attitudes to animals. The concept of karma, as well as that of good versus bad deaths, is probably the foundation of the general Hindu reluctance to euthanasia in any form. Although in theory all species are generally regarded as equal in Hinduism, in practice there seems to be a differentiation; for cultural, religious, medical and financial reasons.
Naturlig förekomst av arsenik och avskiljning av arsenik från grundvatten : test av olika filtertekniker avsedda för enskilda brunnar
During the last few years the presence of high arsenic (As) concentrations in ground water has been of major concern both internationally and in Sweden. Much evidence has been reported about toxic effects caused by arsenic. The carcinogenic effects and the possibility to measure the toxic impacts at low concentrations made the World Health Organisation (WHO) to reduce the guideline value from 50 to 10 ?g l-1 in 1993. In Sweden the corresponding reduction was implemented in 2003.
Several surveys in Sweden have shown that high arsenic concentrations may occur in ground water.
Har kronisk gastrit ett samband med främmande kroppar i mag-och tarmsystemet hos hund?
This master thesis was conducted in order to investigate the effects of the browsing
species Yeheb on animal tissues in Swedish landrace goats and to make a literature
review in order to increase the knowledge of the importance of this plant for livestock
production in Somalia. The evergreen Yeheb bush is a very important feeding source for
grazing and browsing animals in Somalia during the dry period. Yeheb contains
cordeauxiaquinone that stains the bones of the animals red/pink, which has been an
increasing problem when exporting meat to foreign countries. In an experiment, two
goats were fed dry and fresh leaves from the Yeheb bush for one and two months,
respectively. The goats did not feed the intended amount of dry leaves, since the supply
and palatability was not as high as estimated.
Skötselförslag på utvalda nyckelbiotoper i Kalmar och Kronobergs län.
The objective of this study was to contribute with suggestions of nature preservation managements of selected forest objects of high nature values managed by the Swedish state-owned forest company Sveaskog. Many forests with high natural potential are relatively rare today due to modern forestry, where wood production is the main purpose. Sveaskog?s policy is to consider and to priority nature conservation on valuable objects. This assessment includes objects that in the future may develop into nature reserves.
Fokus på folkbibliotekarien ett arbetslivsperspektiv
The purpose of this Master thesis is to illustrate the public librarian. People in general, including library users and leading personalities in the field of culture in the communities do not know the tasks of the public librarian. We presume that the vague picture of duties of the public librarian might cause problems. In this dissertation we mean to examine only public librarians, hereby we exclude for example, university- and company librarians. The sentences of this thesis are: How are the public librarians viewed, in meaning of, tasks, role/-s, comptetence/-s, status and image? And can we call it a "profession" in the classical sense? We answer these questions by using relevant literature, interviews and conference paper.
Tillväxt, överlevnad och skador för provenienser av Banksianatall (Pinus banksiana, Lamb.) i norra Sverige
Främmande trädslag har i modern tid intresserat skogsbruket i sin jakt på ökad produktion, minskad känslighet för skador, förbättrad anpassning med mera. Ett tidigare oprövat trädslag var banksianatallen (Pinus banksiana, Lamb.), en nordlig, välspridd, pionjär från Kanadas inland med en utpräglad etableringsstrategi för torra, nybrända sandjordar.
Studiens övergripande syfte var att utvärdera utfallet från 22 år gamla försök av banksianatall och analysera banksianatallens odlingsvärde i norra Sverige genom att på fem lokaler jämföra överlevnad, tillväxt och skador med tall (Pinus sylvestris L.), contortatall (Pinus contorta var. latifolia Engelmann) och hybriden mellan contortatall och banksianatall. Ett ytterligare syfte var att utreda eventuella effekter av odlingslokalens temperatursumma och trädens latitudförflyttning från ursprungslatituden.
I metoden har fältförsök använts där varje enskilt träd mätts och bedömts. Materialet var insamlat i naturbestånd i nordvästra Kanada från 12 provenienser med en latitudinell spridning av cirka fem breddgrader.
Metodutveckling för analys av serglycinuttrycket i blodet hos hundar :
The development of quantitative, real-time PCR (qPCR) combined with the mapping of the canine genome opens new possibilities in veterinary medicine. This method provides a quick and accurate quantification of the expression of a specific gene at a given point in time and thereby also information of how the gene expression for a certain protein is influenced by various conditions and diseases. One possible area of application is identifying bio markers for cancer. Recently the protein serglycin (the core protein of an intracellular proteoglycan) was found to act as a selective marker for the disease acute myeloid leukemia in humans (Niemann et al, 2007). Serglycin is produced by most hematopoietic cells, although mast cells account for the largest amount of serglycin.
The effects of Gotland pony grazing on forest composition and structure in Lojsta hed, south eastern Sweden
Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.
Skånska trähägnader : en studie i konstruktion och historisk utbredning
The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.
"En gång till!" : en kommunikationsetnografisk studie om andraspråksinlärares deltagande i förskolan
The aim of the thesis was to better understand how second language learners becomes lingual participants in a Swedish preschool. Using the following research questions: In what situations are SLLs lingual participants at the preschool? What does their emerging language look like? Are the participation any different considering children's time in the new L2 context? What kind of support does SLLs receive at the preschool?Two focal children at the same preschool was studied with ethnography of communication as method. The focal children chosen were one girl (Mandarin L1, 4.0 yrs) who arrived to Sweden and started the preschool two months ago at the time of the study, the other a boy (Serbian L1, 3.9 yrs) who started preschool and learning the L2 one year and two months before the study. Situations where the focal children interacted with other children or adults were analyzed. Results showed that the focal children in interaction with each other understands some of the others intentions before being able to speak about them in the L2.
