Effekter av bearbetningsdjup i plöjningsfri odling

In Sweden, reduced tillage usually means non-inversion tillage, where primary tillage is carried out using chisel ploughs or disc implements. Primary tillage method is mainly determined by the desired soil loosening and the handling of soil residues. The effect of tillage depth was studied in field experiments in Skåne, Väderstad, Uppsala, Örebro och Västerås in different crops; spring oilseed rape, spring wheat, winter wheat and spring barley.The experiments generally had a randomized block design with the treatments mouldboard ploughing, deep chisel ploughing and shallow chisel ploughing, in some cases also shallow discing and no-tillage. In the experiments the following parameters were determined: seedbed properties, saturated hydraulic conductivity, penetration resistance, number of emerged plants and crop yield (all parameters were not determined in all experiments. Root growth and draught requirement were determined in two separate studies. There were no significant differences between tillage depths in non-inversion tillage in seedbed properties, plant emergence or root development.

Prevalence of subclinical mastitis in dairy farms in urban and peri-urban areas of Kampala, Uganda

En operation framkallar en icke önskvärd fysiologisk reaktion hos patienten som benämns som kroppens stressvar. Stressvaret innebär att sympatiska nervsystemet aktiveras och att endokrina ändringar erhålls, bland annat minskning i sekretionen av TSH och insulin samt ökning i sekretionen av ACTH, kortisol och ADH. En viktig uppgift för en veterinär är att välja premedicineringsläkemedel innan en operation. Premedicineringsläkemedel har som främsta uppgifter att motverka det perioperativa stressvaret hos djuret, minska smärta och förstärka anestesimedlens effekt. Syftet med det här arbetet är att beskriva vad som händer i kroppen vid ett perioperativt stressvar och hur svaret kan motverkas med hjälp av premedicineringsläkemedel. Premedicineringsläkemedel väljs och kombineras från klasserna sedativa, analgetika och antikolinergika. De vanligaste använda sederande läkemedlen på svenska veterinärkliniker är dopaminantagonisten acepromazin och alfa2-agonisten medetomidin.

Ambulanssjuksköterskors upplevelser av Boussignac CPAP inom prehospital vård

Method: A qualitative study with a descriptive and exploratory approach. Data was collected through ten semi-structured interviews with ambulance nurses, seven men and three women. The analysis was conducted using Lundman and Graneheim?s content analysis.

En välsignelse på jorden : Det goda äktenskapet som normaltillstånd och mål i tre romaner från 1860-talet

The aim of this study is to examine marriage as something both desirable and normal in three popular novels from the 1860s about marriage: Rosa Carlén?s Agnes Tell: en äktenskapshistoria (1860), Marie Sophie Schwartz?s Alma eller De moderna äktenskapen (1860) and Sara Pfeiffer?s Aurora Trampe (1867). Using a theoretical perspective from Michel Foucault and Judith Butler, I have analysed the novels as being producers of, and resistance against, norms.The good marriage is partly depicted as a utopian vision in the novels, which therefore functions as fantasies for the readers. But it is also depicted as a realistic possibility. Though difficult to achieve, the main characters reach the goal through individual improvement towards correct behaviour.The question for the main characters is not whether they are going to marry or not, but how to make their marriages good ones.

Textil halksula

De senaste årens långa och kalla vintrar har lett till ett ökat antal halkolyckor. Genom att undersöka halkolyckors utsträckning samt halkskydd som fanns tillgängliga konstaterades det att ett behov av nya halkskydd fanns. Enkäter för att ge svar på användning av halkskydd togs fram och svar från personer i åldrarna 20-65 visade att man överlag inte använde halkskydd. I stor utsträckning berodde det på halkskyddens dåliga kvalité och den negativa stämpeln som fanns på dem . Textila material undersöktes för att finna lämpliga egenskaper.

Importance of epigenetics in animal breeding : genomic imprinting

ABSTRACTThe aim of this study was to give an overview of the evidence for genomic imprinting in livestock and other mammals as well as outline the potential use of gene imprinting in livestock breeding. Epigenetics is the mitotical and meiotical partial hereditary variation in genomic activity without any alterations of the DNA sequence. An example of epigenetic regulation is genomic imprinting where one allele?s expression differs depending on which parent it was inherited from. These parent-of-origin effects are currently overlooked in livestock production.

Testbänk för motorbåtsdrev

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

Hållbar utveckling och CSR : En begreppsutredande studie

Bakgrund: I Sverige drabbas cirka 30000 personer av stroke varje år varav 20000 är förstagångsinsjuknade och cirka 10000 dör varje år. Cirka 85 % får hjärninfarkt och 15% får hjärnblödning. Nedsatt gångförmåga är vanligt bland personer med stroke och styrketräning och gångträning är två metoder som kan användas i syfte för att förbättra gångförmågan Syfte: Syftet med studien var att sammanställa litteratur kring uppgiftsorienterad träning och styrketräning som behandlingsmetod för att förbättra gångförmågan för strokepatienter. Metod: Litteratursökning på databaserna PEDro och PubMed med sökorden stroke AND gait i kombination med training, resistance training och strength resistance training samt task-oriented training. Efter att ha gjort sökningarna och sållat hittades 12 artiklar som ansågs relevanta för studien.

Genetic variation of ASIP and MC1R in past and present sheep of Gotland

Ovine black coat colour is determined by the MC1R (Melanocortin 1 receptor) and ASIP (Agouti signalling peptide) genes at the Agouti and Extension loci. The black phenotype is caused by production of eumelanin by melanocytes, whereas yellow-tan or light phenotype is the result of phaeomelanin synthesis. The ovine MC1R gene has two known alleles: the wildtype (E+) and the dominant black (ED) alleles. Two missense mutations (c.218T>A and c.361G>A) constitute ED. The presence of a third allele, the e allele, is proposed and believed to give rise to phaeomelanic phenotype.

Implementering av International Baccalureate Diploma Programme vid fyra skolor i Sverige : En utvärdering av motstånd och möjligheter

The aim of this essay is to analyze the implementation process of the International Baccalaureate?s Diploma Programme in four of the approximately 30 schools currently offering the IB at upper secondary level in Sweden. The starting point is a comparison between definitions in fundamental documents in the national programmes for Natural Science (NV) and Social Science (SP) on the one hand, and the IBDP on the other. The evaluation, based on Program theory, focuses in particular on the consistencies in the Organizational plans of each system.  The basic assumption is that the IB due to a deviating organizational system, different structures, aims and objectives makes a challenge for the dominating educational discourse, to use a concept by Michel Foucault, and that resistance against the IB therefore is to be expected.As a second part of the evaluation five people who either play, or have played the role of coordinators of the IB, and who thereby are responsible for the implementation, have been interviewed. The questions have been focused around in what sense the informants can confirm resistance in their implementation work due to the differences found in the first part of the evaluation, and in what ways it manifests itself.Finally, Michel Foucault?s power structures in connection to discourse analysis have been applied on the results of the two previous parts of the essay.

Dräktighetsdiabetes hos hund :

This article presents a retrospective case study combined with a review of the current literature concerning canine gestational diabetes. A total of 14 cases have been collected from six different clinics in Sweden. There are few previously published reports on canine gestational diabetes. Gestational diabetes is a disease that rarely occurs in pregnant bitches. The condition is due to the rise of progesterone that occurs during the estrus cycle.

Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

Från paradox till dilemma : Frantz Fanon om det språkliga våldet och den rasistiska retoriken

This paper aims to explore those yet relatively unexplored dimensions of Frantz Fanons (1925-1961) authorship. Fanon, known to the world as a theorist of violence and revolution, was one of the first to ever map the language of the colonizer. The language of the colonizer was, as Fanon would have it, imbued with different notions of time, constructions of historicity and ideological principles of individuality that would dehumanize the colonial subjects. In line with that the colonizer would also speak of the colonized people in what Fanon called zoological terms. From within those different notions emerged a racist rhetoric consistent of, to quote Richard Delgado, words that wounded.

Immunoglobulin VH gen analys in human B-cell

Malt lymphoma is a malignant disease that can arise in a variety of extra nodal sites. Previous studies indicate that tumour arise from more mature B-cells.Our purpose was to examine the presence of clonality and somatic hypermutation of immunoglobulin (IgV?) of MALT lymphomas.Paraffin-embedded tumour samples from13 MALT lymphoma were subjected to rearrangement analysis, by using PCR, heteroduplex gels and sequence analysis.Successful amplification was seen in 10/13 cases and sequences of IgV? genes were obtained in 6/13, all of them were mutated. The percentage of mutation compared to germline sequences was 1,1% to 8,6% monoclonal rearrangemang. It was demonstrated that 5 of 7 clones were derived from the V?3 family, 2 from V?1 and 1 from the V? 4 family..

Radikala ändringar av marknadsförhållanden och strategiska förändringar

There is much literature covering strategic change under different circumstances but very little concerning how companies act strategically under sudden and radical changes to market conditions. Based on three different events (the terrorist attack in the USA September 11th 2001, the Tjernobyl accident April 26th 1986 and the Islamic revolution in Iran 1979) with such radical changes as a result we chose three companies that were affected (SAS, Asea Atom and Atlas Copco). The result of the events that were studied in this thesis is extremely unusual to their character. The events themselves were sudden and of a temporary nature but the results were long term changes of market conditions. Through personal interviews the authors have tried to establish how the companies have perceived the events and how the top management has strategically handled the situation.
