Inverkan av betessläpp på celltal och mjölkkvalitet hos mjölkkor :

In Sweden regulations stipulates that dairy cows are kept on pasture, or given the opportunity to spend time outside during a coherent period of between two to four months, depending on region. The transition out to pasture is a big change from the winter period in the stable, especially for the modern high yielding dairy cows. The let out to pasture includes a change in feed, environment, and new routines. There are indications that the milk somatic cell count (SCC) rises in a peak shortly after the let out. The purpose of this study was to see if peaks in the SCC could be observed after the let out, and to study the contribution of inflammatory cells (neutrophils) and if the milk composition are affected. The study included 35 cows that were kept in stable during the winter.

Försämrad korrelation mellan storleken av Kebnekaises sydtoppsglaciär och andra klimatindikatorer

Intergovernmental Panel on Climate Change (IPCC) recognizes glaciers as the best land-indicator of climate change. A variety of studies have concluded, using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the summit-glacier constituting Kebnekaise's south summit (called the Southern-summit henceforth), Sweden's highest point, is studied to see how it is affected by winter precipitation and summer temperature during the period 1968?2013.

Osäkerhet i energisimuleringar av flerbostadshus : Analys av fem nybyggnationer

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.

In the light of this, the purpose of this candidate thesis is to investigate healthcare social workers understanding of practical- and theoretical knowledge in the working process as well as their respective influence and importance. This candidate thesis is based on three interviews with social workers from different departments in Norrlands Universitetssjukhus in Umeå, Sweden. To provide range to the thesis, the interviewees were chosen from a purposeful sampling.

Quantification of Tripeptidyl-peptidase II : Optimisation and evaluation of 3 assays

Abstract Tripeptidyl-peptidase II (TPPII), is present in most eukaryotic cells. It cuts tripeptides from the N-terminus of peptides and is especially important for degrading peptides longer than 15 amino acids. TPPII also tailors long peptides into suitable substrates for the enzymes which transport and produce the peptides that MHC I present. Increased levels of TPPII have also been found in certain cancer cells, thus it is of interest to determine if TPPII could be used as a tumour marker.The aim of this study was to optimise and evaluate 3 different methods for quantifying TPPII. Western blot, enzyme-linked immunosorbent assay (ELISA) and fluorophore-linked immunosorbent assay (FLISA) protocols were optimised regarding incubation times and antibody dilutions.

Interdependence between seed age and aerated steam treatment intensities

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

Avel och fruktsamhet hos nordsvenska hästen : en enkätundersökning

The fertility of the North Swedish horse was investigated using a questionnaire. Data concerning altogether 73 North Swedish stallions and 213 mares used for breeding during the season 2005 were collected and analysed. The survey also included the analyses of 305 breeding case books, especially distributed for this study, from 27 stallions. The aim was to collect information on how the breeding was carried out in the North Swedish horse, and to learn what categories of mares that were covered and what routines were used in these farms. Breeding statistics from 1999 to 2004 was also analysed to complete the questionnaire.

Gymnasieflickor & idrott och hälsa : Faktorer som påverkar flickors motivation till att delta fysiskt i undervisningen

The aim of this piece of work is to highlight and investigate young female?s motivation in participation of P.E classes and the degree to which the content of classes affect their motivation. To support this piece of work two theories have been utilized, the Self-determination Theory and a gender related perspective theory. The research consists of six qualitative interviews of young females who are perceived to be less motivated. These interviews focus on their views and attitudes in relation to P.E within the Swedish high school setting.

 Solenergi En del i ett långsiktigt, hållbart byggande

The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.

Svampar associerade med raps : betydelse för uppkomst och grödetablering

Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems. This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens. The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.

Närproducerat : Attityder och definitioner bland Uppsalastudenter

From an environmental and climate perspective we are becoming more and more aware of what we eat. Consumers want to know how their food is produced and where it is coming from. A term commonly used in this discussion is local produce. At this time, there is no clear definition of the term and a wide range of definitions can be found. However, despite this lack of definition, the term is often being used by producers, traders and consumers..

Layers of land : the palimpsest concept in relation to landscape architecture

This paper researches how the palimpsest concept is used in relation to landscape, and how it can function as a tool within landscape architecture. Palimpsest originally refers to old parchment handwritings, where new text has been applied on top of effaced, but still discernable, earlier writing. Superimposition of information is the core of the palimpsest concept, used within a range of scientific as well as cultural fields. The purpose of this paper is to find how a landscape palimpsest can be distinguished among the many different layers of landscape, such as historical or cultural, and to examine the potential use of the concept in theory and practice of the landscape architecture field. The study is conducted as a literature survey, examining the use of the palimpsest concept within academic works related to landscape.

Solenergi och värmelagring i kvarteret Lagern

Humanity stands before a huge challenge to lower its emissions of carbon dioxide and its use of energy at the same time as the global population is rising and the developing countries are being industrialized. A lot of newly built buildings are due to this challenge, designed to be more energy efficient but also use renewable energy resources instead of pollutant fossil fuels .Solar energy is one of the purest forms of energy that exists in abundant amounts, which is why it is most likely that it could come to play a major part in the future energy market. The main purpose of this report is to investigate the possibility to implement a sustainable energy system with solar thermal heat and  heat storage as main sources of energy in the neighborhood ?kvarteret Lagern?, which is the area where the old football stadium ?Rasunda Stadion? was located. New developments within different heat storage techniques have opened up new approaches to enable buildings an all year round heat supply from solar energy. This report will focus on heat storage in boreholes. At the present here is only a preliminary plan of how the neighborhood is supposed to be designed.
