Fortsatt gran eller självföryngrad björk efter stormfällning? : en ekonomisk analys

The southern part of Sweden, Skåne, is frequently exposed to storms causing great damage to Norway spruce (Picea abies L. Karst.) stands. A storm during the winter 1999/2000 raised the attention of the problem. A lot of forest owners got large areas of spruce stands wind thrown during this storm. Can naturally regenerated birch (Betula sp.) be an alternative on these wind-exposed sites? This was the main question I was facing when discussilig the problems with Esben Möller Madsen, Söderåsens forest district. The aim of this master thesis was to present an economic analysis of Norway spruce versus birch.

Inverkan av utfodringsnivå och miljö på reproduktion och hållbarhet hos rekryteringskvigor :

This study is based on an earlier interdisciplinary study made by Redbo et al., (2000), Extensive cattle production systems ? out wintering, which lasted over two winters, 97/98 and 98/99, with two groups of heifers indoors and two groups of heifers outdoors raised in different environments, indoors or outdoors during their second winter. Both indoor and outdoor heifer groups were fed grass silage ad libitum throughout the experimental period that lasted from October until May. The objective of this study was to evaluate the long term effects of being raised in these two environments. This study includes data collected during the period lasting from the start of the experiment of Redbo et al., (2000) until the heifers had calved a second time and the results mainly deal with the performance of the animals after the experiment during their first two calvings and their first lactation.

Expansionsmaskiner istället för strypventiler - en effektivisering

In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.

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.

Majs till mogen skörd :

Corn is an important food and feed crop in the world, in Sweden it?s up till now grown on limited acreages mainly for silage. But I think it can get more important if you can grow it also for grain, because it?s a good animal feed for example, for life stock-, pigsand poultry. On of corns advantage is that it can produce the same amount of dry matter as for example wheat, barley and rise but with 25% less water. I will examine if it possible to grow corn for grain production in the south of Sweden.

Riskhantering av kritiska infrastrukturtjänster : En studie av Apotekens Service ur ett HRO-perspektiv

Risk management has become a key ingredient for businesses all over the world. High Reliability Organizations (HRO) has distinguished themselves as experts in this area. By continuously focusing on improving their ability to manage risks they?ve been able to successfully avoid catastrophes in environments where normal accidents can be expected due to complexity and risk factors.The aim of the thesis is to improve the risk management at Apotekens Service by applying theories from HRO and safety culture. In July 2009, following the re-regulation of the Swedish pharmacy market, Apotekens Service AB was appointed national pharmacy infrastructure supplier for the Swedish health care system.

Ett steg närmare Just-in-Time : En studie av JIT-försörjning vid GGP Sweden AB

This study looks into the possibility, and profitability, of expanding a pilot project that has been put into action at GGP Sweden AB in Tranås, a manufacturing company that produces front mowers. The pilot project is meant to give GGP Sweden AB a more precise control of the flow of goods from their suppliers, and its essence has proven to be quite similar to the Japanese Just-in-Time philosophy.The study has been divided into four separate areas; mapping, supplier selection, supplier evaluation and cost analysis. These areas represent a holistic perspective on the expansion of the pilot project and cover topics varying from methods of finding suitable JIT-suppliers, constructing Key Performance Indicators (KPI) to reviewing costs and assessing profitabilities.In this report, the reader will initially take part in the works of mapping GGP?s manufacturing unit, pilot project and supplier base, which results in a list containing the most suitable suppliers for a Just-in-Time based collaboration. Afterwards, the reader will be led into the area of supplier evaluation, where five KPI?s are created with the purpose of ensuring that GGP will be able to evaluate their suppliers and pilot project in an effective way.

Objectives: The aim in this thesis has been to generate information relevant for strategic positioning and future evaluations within the scientific field of sport and exercise psychology. This has been done by request, and in collaboration with The Group of Sport and Exercise Psychology at the Institution of Psychology at the University of Umeå.Research questions:  (1) How does the cognitive structure within the field of sport and exercise psychology take shape with respect to research topics in current sport-psychological research, i.e. the research front? (2) How does the social structure within the field of sport and exercise psychology take shape with respect to formal scientific collaboration?Data: 879 articles published between 2008-2011 were used in this study. The population of articles were collected from a set of 5 core journals: International Journal of Sport Psychology, Journal of Applied Sport Psychology, Journal of Sport and Exercise Psychology, The Sport Psychologist, Psychology of Sport and Exercise.

Riskhantering : Hur applicerar svenska fondbolag teoretiska riskhanteringsmodeller i praktiken?

There are different types of risk, examples include credit risk, liquidity risk and financial risk. In DeMarzo & Berk (2011, s. 293) is a study presented which is based on the yield of different types of financial assets between 1925 and 2009, the study show that a high risk gave substantially higher reward. With the study as a background, it is interesting to study practical risk management within participants of the financial markets of Sweden. In risk management there are several theories about whether risk can be calculated and analyzed with scientific methods in practice.

Effekten av mjölkkors rang på ?antistresshormonet? oxytocin, mjölkavkastning, mjölkflöden och besökstider i mjölkningsenheten i ett automatiskt mjölkningssystem :

The study was carried out at the Kungsängen Research Centre, Department of Animal Nutrition and Management, Swedish University of Agriculture Sciences, Uppsala. The technical development in dairy production has resulted in a housing system where feeding and milking is done automatically without human contact, a so called automatic milking system. The motives for utilising an automatic milking system, is to increase the animal welfare and to decrease the need for manual labour. However, the system does involve a change for the animals, among the effects is the deprival or the diminishment of a chance for synchronous behaviour and the animals have to agree among themselves in which order they use the feeding stations and the milking unit itself. How and if this affects the animals well-being and production is yet to be solved. A possible way to form an opinion on this, is to study the animals ranking order along with hormone profiles and production. The purpose of this work was to study the effect of low- vs.

Central Peripheries: speculation and strategy for a land less mentioned

As the contemporary discourse surrounding urbanism is almost exclusively focusing on aspects of density and traditional urban qualities, it entrenches notions of what constitutes a proper city and countryside. But beyond this urban-rural dichotomy is another highly contemporary landscape. A territory usually mentioned as sprawl, peri-urban, wasteland, edge city, etc. Although its existence is due to mobilization, telecommunications, globalization and other phenomena of modern life, it is a landscape without an own name or place in public awareness.This thesis provides a case study of how to map and intervene in such a landscape, specifically along the border between Malmö and Burlöv municipalities in southern Sweden. Its structure is composed of a sequence of three parts:1 Spatial Conditions:Divided up in the sections Network, Fringe and Void.

Riskfaktorer för Staphylococcus aureus i mjölk och på has hos mjölkkor :

Mastitis is the most common disease of dairy cows. Mastitis can be painful for the dairy cow and causes economical losses for the farmer. These losses are due to decreased milk production, more working hours for the farmer, treatment costs and possible costs due to culling of the cow. The udder inflammation, mastitis, is often caused by bacteria infection. One of the most common bacteria found to cause mastitis in Sweden is Staphylococcus aureus (S.

Översvämningsrisker längs Funboån

Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.

Framgångsfaktorer och hinder med Lean produktion i Kina

AbstractLean production has become one common concept within industries to make the work more effective and to meet today?s hard competition. A challenge for Chinese production is the threat from new low cost countries. It will become very difficult to succeed to produce to a lower cost than these countries; this led to that Chinese companies must develop new strategies, according to Lee and Zhou (2000). This will put China in front of new challenges and new strategies can be needed to retain their strong competitive advantages.
