Naturvärdesbedömning av Utanåfladen; En inventering av vårlekande fisk, bottenfauna och vegetation
There are several thousands shallow bays along the Swedish east coast. Most of them are disturbed by different human activities, and undisturbed bays can be considered as quite unique. In the sheltered shallow bays water warms up more rapidly than adjacent water favoring the growth of vegetation, which in turns is beneficial to spring spawning fish species like perch and pike. It is nowadays more common that coastal habitats are inventoried to facilitate future preservation and planning. The aim of this study was to investigate the shallow bay Utanåfladen (59° 53`31.38 N 19°00`44.90 E) in the north Stockholm archipelago and evaluate its habitat value.
Undersökning av potentiella probiotiska organismer i tarmmikroflora hos häst med speciell hänsyn till Lactobacillus spp. :
The aim of this study was to isolate and identify Lactobacillus species indigenous to the gastrointestinal microflora of Swedish horses. These lactobacilli are to be used as probiotic candidates in research concerning antibiotic-associated diarrhoea in horses.
Eight horses, age 6-10 years, were selected from a riding school for collection of faeces samples. Man Rogosa Sharp medium and gram staining were used for the selection of supposed lactobacilli. We could identify 33 isolates of supposed lactobacilli. With the use of API tests 22 of these 33 isolates could be identified.
Bestämdhet eller inte : En textanalys av andraspråkselevers muntliga och skriftliga berättelser. Utvecklingen av bestämdhet inom nominalfrasen
I denna uppsats kommer muntliga och skriftliga berättelser av andraspråkselever på Komvux att analyseras med hjälp av performansanalys. Syftet med studien är att se på utvecklingen av bestämdhet inom nominalfrasen och i fall det sker i enlighet med processbarhetsteorin. Det kommer även att ske en analys mellan den muntliga och skriftliga produktionen för att åskådliggöra eventuella skillnader i utvecklingen av bestämdhet.Resultatet visar att det finns belägg för processbarhetsteorin och att detta kan tillämpas på nominalfraserna och dess bestämdhet. Resultatet visar dock inga generella skillnader mellan utvecklingen av bestämdhet när det kommer till skillnaden mellan muntlig och skriftlig framställning. Däremot kan man uttala sig om individuella skillnader hos informanterna..
Om behovet av ett avrinningsområdesanpassat skogsbruk
The Swedish forest have about 100 000 km of watercourses and it?s an important structure in Swedish landscapes and catchments. In some of the watercourses lives spieces like the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) which both are sensitive for inteference from the forestry. The new EU water framework directive has a goal that all surface water will have high or good ecological- and good chemical status at latest by the 22nd December of 2015.
The study has been made in the catchment of Håltjärnsbäcken and it is from a national perspective one of the most valuable streams in Sweden and which also have been included in a LIFE-project. The catchment is situated within the Eco-park of Malingsbo-Kloten and managed by Sveaskog AB.
Vatten som säkerhetsfråga : Med FN:s konstruktion av vattenfrågan som utgångspunkt
ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..
De talar av erfarenhet : uppfattningar om begreppen demokrati och diktatur hos vuxenelever med utländsk bakgrund
I have in this study examined, through qualitative interviews, how adults with foreign background that are pupils in adult education in Sweden, understand the concepts democracy and dictatorship. Their expressed understandings have been compared with their former life experiences as well as with the aim of the social studies to create a qualitative understanding of essential social concepts. My starting point is theories about the adult in leaning processes. It has been assumed that the adult interprets the world much through former life experiences. I have also relied on the idea that having a qualitative, more scientific, understanding of essential subjects is important for the adult as a member of society and participator in the on-going political debate.
Djurskyddskontroll av reptiler och sällskapsfåglar. Kan djurskyddsinspektören göra en bra bedömning?
Reptiles and birds are animals that many people don?t have much experience of, so it can be difficult to do a proper animal protection assessment of these animals. It?s hard to determine if these animals is skinny, fat or in good shape, to do that it demands handling of the animal and not many inspectors that works with animal protection have experience of handling reptiles and birds. To see if a reptile or a bird is ill is difficult, when the bird or reptile looking sick it?s often too late to do something.

Yeast in forage crops and silage aerobic stability at 15 Swedish dairy farms
This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos.
Chemical analyses and yeast counts were performed for fresh crop and silage.
"Den stora stygga vargen?" : En argumentationsanalys om vargens moraliska värde i vargdebatten
The purpose of this paper is to see which ethical content arguments have in the debate about wolfhunting, particularly with regard to the Svensk Jakt respective Tidningen Djurens Rätt's arguments. The method used in this paper is the analysis of arguments in which I investigate the pro and contra arguments of the four authors of the articles that I have chosen to study. I will avail myself of theories from Carruthers and Franklin. Analysis shows that the authors of the Swedish hunting above all have a ecocentric view of the wolf where it is an instrumental value for the ecosystem, and the authors of Djurens Rätt's has especially a biocentric view of the wolf where it may be an absolute value, but they can also extend to the that the wolf has instrumental value in the ecocentric perspective. The discussion has shown that Djurens Rätt's and Svensk Jakt has a common position that is an ecocentric perspective where the wolf has instrumental value, even though they believe that different actions are different law to protect the species and the ecosystem..
Stora och mäktiga sanningar : En studie av några populärvetenskapliga framställningar av Charles Darwins idéer i Sverige 1859-1909
Uppsatsen undersöker några svenska populärvetenskapliga framställningar av Darwins idéer under halvseklet efter publiceringen av On the origin of species. De publikationer som studeras mest ingående är Ny illustrerad tidning och Verdandis småskrifter. Med hjälp av Ludwik Flecks vetenskapssociologiska tankar, jämte ett antal andra perspektiv på polulärvetenskapens form och funktion, resonerar jag om populariseringarnas folkbildande och stundtals politiska syften och sätt att presentera en omstridd teori som ovedersägligen sann. Uppsatsen innehåller också en översikt över populärvetenskapens historia i Europa och Sverige..
Järnåldersgården som försvann : En studie av produktion, tafonomi och brända ben från möddingen vid gården Långåker från romersk järnålder
This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).
Så långt inuti, näst intill borta
Through wing pattern, posture and movement, a harmless moth of the family Brenthia imitates an eight-eyed jumping spider. When an octopus of the species Thaumoctopus mimicus sense danger it can alter its appearance to that of a venomous sea snake. They are both drawing attention to themselves. Nevertheless, and because of this, they are protected. The mechanism is called mimicry.
Spaljerade frukttr?d, en outnyttjad resurs f?r hemtr?dg?rden? En intervjustudie av tr?dg?rdsm?stares erfarenheter och syn p? hantverket spaljering.
This bachelor's thesis is a study of operative approach and attitude to espaliered
fruit trees in home gardens. Through qualitative interviews the informants give their view of
problems which might arise, and to some extent how the problems can be solved. In
addition, which benefit can be obtained from growing these different types of trained trees
and for whom they might be suitable. Thematic analyses were used to find themes and
patterns for deeper understanding. The conclusion was that these kinds of trees would be
beneficial to use to a greater extent than is done today you can use more species and
varieties, fit more trees in a small garden, and enhance the trees esthetical appearance.
Evaluation of a method for determinationof glutathionereductase activity inerythrocytes
Glutathione (GSH) is a molecule that consists of three amino acids: glutamic acid, cysteine and glycine. GSH has several important functions: to protect cells from free radicals, reactive oxygen species and oxidative stress. GSH exists in a reduced form, GSH, and in an oxidized dimeric form, glutationdisulfid, GSSG. The enzymes glutathionereductase (GR) catalyses the reduction of GSSG back to GSH. Nicotinamide adenine dinucleotide phosphate (NADPH) is required as a coenzyme in the reaction.
Modeller för brösthöjdsålder för tall och gran :
The purpose of this study was to develop two types of prediction models for Scots Pine
and Norway Spruce. The first type for calculation of the stump diameter under bark the
year the tree reached breast height (Dstubh130). The second type for calculation of the
annual difference, e.g. the number of growth years between stump height (0.2 m) and
breast height (1.3 meters above ground level). The primary thought with these prediction
models is to obtain the breast height age in the trees on basis of the number of annual
rings at stump.
