Effekt av överlast på förstärkt jord : FEM- analys för att visa överlastens verkningsgrad på krypsättningar i kalkcementpelarförstärkt lös jord
Applicering av överlast på kalkcementförstärkta jordar är ofta förekommande idag, forskning indikerar dock på att överlasten här, inte ger samma effekt som på oförstärkta jordar. Med grund i uppmätta värden i fält, visas i denna rapport, sättningsdifferenser mellan att använda överlast jämfört med att endast applicera brukslast. Resultat av analyserna visar på sättningsbeteende observerat i fält. Om erforderlig liggtid för brukslast finns, uppstår endast små sättningsdifferenser mellan att använda överlast eller inte.Genom att utföra sensitivitetsanalys i FEM- programvaran PLAXIS studeras kryputvecklingen i den förstärkta jorden. Effekten av att applicera en överlast visas för krypsättningar över lång tid.Inget resultat från de numeriska FEM- analyserna visade att märkbart gynnsam effekt uppstår på grund av överlastens applicering, med avseende på krypsättningar.De numeriska analyserna utförs i 2 och 3 dimensioner för att belysa effekt av förenkling av ett lastfall som inte uppfyller krav för oförstärkta jordar i plant töjningstillstånd.Utöver detta ges efter en litteraturstudie, förslag på hur vissa indataparametrar kan utvärderas från empiriska relationer.
Olika typer av täckning och samodling och dess påverkan på antalet skadegörare i en Pak choi odling :
The purpose of this report is to examine the possibilities to decrease the number of insects and other pathogens in a crop of pak choi (Brassica rapa), grown with different types of cover and living mulches. Included in the report is a study of literature where amongst others, a summary on the vegetable pak choi and theories of living mulches and different kind of covers are to be found. To examine the amount of predators in the field, traps were used.
During the autumn 2002 the tests were conducted in Alnarp. The pak choi and the living mulches were planted/sawn at the same time, the different covers were also applied at this time. The total experiment was divided into six different treatments (plus control) of which three were with covers and three were with living mulches.
Once a week the number of leaves, the height and damages were read on ten of the plants from each parcel.
Tre metoder för diagnos av mastit i fält :
The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings.
DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations.
Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.
The Never Ending Story : En läroplansteoretisk studie om GY11-reformens påverkan ur ett lärarperspektiv
New national curriculums are issued in order to change the present state of the educational system in a nation. In 2011 the old curriculum, the Läroplanen för de frivilliga skolformerna (LPF94) was replaced by the Läroplan, examensmål och gymnasiegemensamma ämnen för gymnasieskola 2011 (GY11). As future teachers we are interested in how a new curriculum affects the work of teachers concerning planning, teaching and examination from the teacher?s point of view.We conducted interviews with five teachers working at upper secondary schools (16-19 year olds) in Kalmar county. Our theoretical framework is based on curriculum theory and concepts of Leonard Bernstein: framing and classification.
Fosforförluster från lantbruket och dess bidrag till övergödning av sjöar och vattendrag i Växjö kommun
The possibility for plants to utilize phosphorus in soil is a prerequisite for conducting agricultural production, both small scale and professional. Spreading of phosphorus fertilizers and manure is therefore seen as a necessity in today's agriculture in order to achieve high yield. Manure management, livestock farming and manure storage could contribute to the eutrophication of lakes and rivers. For instance, when the ground becomes saturated, phosphorus leakage could be seen in surface runoff or in point sources resulting from inadequate manure storage management.In the municipality of Växjö there is still many bodies of water that do not reach the Swedish environmental water quality standard of "good ecological status". This thesis has therefore analyzed the manure management and storage on agricultural farms which may have contributed to eutrophication in the municipality.The method for this thesis was a literature study, a questionnaire survey with 820 receivers and a summary of issued inspection reports from 2013.The results highlight the ways in which agriculture may have contributed to the eutrophication of lakes and streams in the municipality of Växjö.
Fallstudie av 10 skånska gårdar för en lönsam stutproduktion :
During the summer of 2005 a number of steer producers in Skåne, Sweden, found that their animals graded less favourable according to the EUROP carcass grading system when slaughtered, than ordinary. The aim with this project was to determine factors that affects the production result in steer production and to find the reason to the lower classification. The project was initiated by Anita Persson, LRF, Skåne and was preformed with supervision from Ingemar Olsson, SLU, and Jens Fjelkner, Skånesemin. Ten producers of dairy steers located in Skåne was chosen for this study. The producers were interviewed to collect information about their steer production with respect to their planning and results.
It´s a way of understanding the universe while leaving the universe unexplained : Sökandet efter det autofiktiva jaget i Jeanette Wintersons Oranges Are Not the Only Fruit
In this essay I examine the auto fictive self in Jeanette Wintersons Oranges Are Not the Only Fruit. I do this through a close reading of the novel using Mieke Bals narratological terms;narrator, story, fabula, time and order. These narratological terms have been merged together with central themes of the book. I look at the readers understanding of the novel, the relation between fairytale and realism, symbols, intertextuality, the mother-daughter relationship and silences and I analyze these themes in their relation to autofiction and the auto fictive self. Gemma Lopez Seductions and Narratives has been a key reference, mainly her theories on self-creation in narratives, and the construction of the self, trough language. The narrative is the place where the self can transgress and reshape, which gives the narrative a subversive power. I analyze this presumed power, and look at how the story shapes an opportunity for the subject to see itself.
En studie av olika ekonomiska modeller för mångbruk baserad på vindkraft
Today produces the wind power 2,5 TWh (TWh = terawatt hours) of Sweden?s total energy input of around 620 TWh. The Parliament has adopted a national planning objective where the wind-based electricity production will increase to 30 TWh in 2020. This requires that landowners will leas there land for wind power to wind energy companies. Such land leasing means that the landowner's business is considered to be a multiple-use.
Application of Design for Safer Urban Roads and Junctions: Selected Countermeasures
Road design with focus to safety has been extensively developed in last decades in Nordic and some other EU countries with the main aim to achieve a decrease in a number of accidents and fatalities on the roads. These countries gained many valuable experiences, but they had to sacrifice great effort, expenses, and time to reach the present art-of-state. The purpose of the Master?s Thesis is to review some design approaches with focus to safety and discuss the general way that they may be applied. The Master?s Thesis studies safety in three levels: (i) general - design standards, national safety policies and road hierarchy; (ii) local authority and road administrator; and (iii) three specific safety countermeasures - junctions, pedestrian crossings and traffic calming.

Dopning vid hästbesiktning
The aim of the project was to investigate if Swedish rodents, brown rat (Rattus norvegicus), house mouse (Mus musculus), wood mouse (Apodemus spp) and water vole (Arvicola terrestris) captured in pig herds and in urban areas, constitute a reservoir for pathogenic Leptospira spp. Under Swedish conditions leptospirosis gives rise to reproductive disorders in pigs and symptoms of flu in humans. It has long been established that rodents are chronic carriers of pathogenic leptospires in their kidneys, and can spread the bacteria with urine. The old nomenclature of serovoars is still in use, but a new system of genetic classification has developed and today the genus Leptospira contains 17 species. There are several diagnostic test developed for leptospirosis.
Do retention trees affect the composition of ectomycorrhizal fungi? : a comparison between clear-cuts areas with and without retention trees in pine forests
Under det senaste årshundradet har de svenska skogarna genomgått en omfattande förvandling, från mer eller mindre naturligt dynamiska till hårt brukade skogar bestående av monokulturer av tall eller gran. Denna förändring har lett till en minskning av den biologiska mångfalden, att många arter som är beroende av skog har minskat radikalt och hotas av utrotning. Som ett försök att främja variation, biologisk mångfald i allmänhet och förhindra minskningen av rödlistade skogsarter introducerades i början av 90-talet en viss naturvårdshänsyn i brukade skogar. I den här studien utvärderas den påverkan som kalavverkning har och den betydelse hänsynsträd har på artsammansättningen och förekomsten av ektomykorrhizasvampar (EMF) under de första 20 åren efter kalavverkning. Studien utfördes genom extrahering och identifiering av svamp-DNA från jordprover tagna på kalavverkade ytor, nära hänsynsträd och i gammal skog i ett begränsat geografiskt område i norra Sverige.
Verksamhetsanalys Jämförelse mellan IAEA och OKG AB inom E.ON-koncernen
The safety and safety work on OKG, Oskarshamns Kraftgrupp, is supervised by SKI, Swedish nuclear power inspectorate. The task of SKI is to inspect that the nuclear power plants of Sweden runs in a safe way. The proprietor of the permit who runs nuclear power plants has the responsibility to maintain the required safety to run a plant. SKI publishes a number of statue books that OKG has to meet to be able to run the plants. SKI recommends in SKIFS 2 004:1, that OKG work with the safety requirements of IAEA.
The effect of vegetable fat on cheese yield and cheese properties
The production of cheese is in continuous development with objectives to in-crease productivity, achieve changes in shelf life and functional properties of the products. One concept in the development is to substitute milk fat with vegetable fats and oils in the manufacture of cheese.
The objective of this study was to investigate effects on cheese yield and cheese quality of 4 different semi-hard analogue cheese products produced by substituting milk fat with vegetable fat, each analogue cheese with a specific mixture of vegeta-ble fat. As reference a cheese produced with anhydrous milk fat was used.
The yield and recovery of fat and protein were determined by recording the weights of each cheese direct after press and after 20±2 days of storage and analysis of the composition of the cheeses after 20±2 days of storage. The cheese was fur-ther subjected for texture profile analysis in a TA-XT Plus Texture Analyser and analysed with Differential Scanning Calorimetry (DSC) to examine whether the fat behaves similar in the cheese as in pure form in respect to its thermal properties.
The cheese yield was not significantly different when using different fats. Differ-ent amounts of water were absorbed during the water cooling.
