The use of combi-drilling during spring tillage has become very common in southern Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and seed coulters, which means that the draught requirement is relatively high. It thus requires large, heavy tractors, which compact the soil and are comparatively expensive to buy and run. A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish market.

At Forsmark nuclear power plant a new course called "education in everyday safety" has been started in an attempt to improve the safety culture. The goal is to spread the of expectations and approach the maintenance management has set, to all employees working at the plants. During the course, theory is mixed with practical tasks to reach a common view how work should be done to achieve safety for the plant and the people that work there.The practical tasks are done inside "maintenance simulators". They are built inside 20 ft containers which contains two dummy pipe systems. On the pipe systems some valves, a flow meter and a pump has been installed.

This diploma work covers an investigation over the heat - and hot water systems of thetenant-owner's association, Bogården. The heat - and hot water needs of Bogården aresatisfied by both district heating as well as three heat pumps. Implemented investigationshows that the heat pumps are not used in a profitable way. Apart from that, the reservepossibilities are small. There is also a risk of the growth of Legionella bacterium in thehot water system.Since the heat pumps are already installed, HSB-Gävleborg (responsible for Bogården)has a wish to investigate possible proposed actions for optimization of existing plant.After completed investigation, a new proposed action is presented.

Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.

The aim of this thesis is to analyze children?s picture books regarding whether and in what form gender stereotypes can be seen in these. The purpose is also to evaluate whether the findings correlate to the different regulatory documents libraries have to abide to.       The study comprises five books, who are part of a selection of books especially chosen by Uppsala City Library to be used by primary school children aged 6-9. The method used is the study of text as well as illustrations, as the theory of this thesis is that the two cannot be separated, but has to be seen a unit. Other theories used in the analysis include Nikolajeva?s schedule of male/female properties and theories on gender.      The result of the study shows that gender stereotypes are in majority regarding the characters in the books, but that the opposite also exists.

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

This candidate thesis contains the possibility of expand the Swedish photovoltaic market through photovoltaic cooperatives and a photovoltaic exchange. In the current situation there is a lot of problems with production of electricity from photovoltaic, that?s why we show some possibilities how to avoid these. To understand the problem with photovoltaic produced electricity we first give you a background.We show how to expand the Swedish photovoltaic market by describing how a photovoltaic cooperative and photovoltaic exchange could work in Sweden. It have been confirmed from our market research that the interest of photovoltaic cooperative and exchange is high.To find out how profitable photovoltaic is in Sweden, have three projections been made.

SummaryHerbal remedies have been used for many years to alleviate various symptoms. They were used in ritual acts to reassure the Gods and as medication. Plants as rhubarb and ginseng were used in China long time ago. The Egyptians had knowledge of herbal medicine such as aloe, myrrh and henbane, 1550 BC. The father of medicine Hippocrates used a large number of herbal medicines, and had many theories on the subject.Different parts of the plant can be used to extract the active ingredients.

The thesis of this essay is how literary texts are selected in the teaching of Swedish in upper secondary school, and how teachers reflect upon gender in these selections. To answer the thesis question three methods have been used. Firstly interviews were held with five teachers of Swedish, which have been the primary source for the essay. In addition to the interviews, I have examined two literary anthologies used as teaching aid in the teaching of Swedish and lastly I analyzed the literature and authors that the teachers explicitly express that they use in their tutoring. The secondary sources of this thesis contain research on selections of fictional texts, literary canon and students? re-production of gender.

This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed. For further notification, I am not   responsible for the programming of the devices in LabVIEW   which I have only used as a tool in my work. The plant   for production of biogas consists of four reactors   of which the third reactor (Lakbädden)   is connected to another reactor (UASB)   where they cooperate with each other.   The reactors are used for producing   biogas in the form of methane gas.The reactors I and II are   connected to, various electrical devices as, flow meters, temperature   sensors, frequency converter and   more.

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

Globally, coastal ecosystems like mangrove forests, sea grass meadows and salt marshes are well known for their ability to capture and store atmospheric carbon effectively. In Sweden, there is still limited knowledge about local coastal ecosystems with similar functions, with alder swamp forests being an interesting example. Therefore, this study aimed to increase knowledge of the factors that can contribute to the potential carbon sequestering ability of alder swamps. Vegetation data and sediment samples were collected from a total of 37 sampling plots across four alder swamps in Bohusl?n on the Swedish west coast.

Kalvningssvårigheter och dödföddhet är problem som finns hos svenska mjölkkor och som ökat under de senaste åren, speciellt bland förstagångskalvare. Problemen försämrar kornas välfärd och kostar pengar för bonden. Flera studier har gjorts för att kartlägga så kallade quantitative trait loci (QTL) kopplade till kalvningsegenskaper och många kromosomregioner har hittats som kan innehålla gener som påverkar dessa egenskaper. En viss oenighet finns i resultaten från studierna, men flera studier har hittat QTL kopplat till kalvningsegenskaper på kromosom 4, 6, 7, 10 och 18. Sverige har inkluderat kalvningssvårigheter i det traditionella avelsprogrammet sedan 1995 men inga större genetiska framsteg har gjorts.

Hög sjukfrånvaro är en ständigt aktuell fråga i Sverige. Förutom problemet med hög sjukfrånvaro i absoluta tal finns i Sverige även stora regionala skillnader i sjukfrånvaro som inte kan förklaras med skillnader i hälsostatus mellan olika regioner. För att sjukförsäkringen ska få mer karaktär av försäkring med mindre godtycklighet i ersättningsbedömning krävs en tydligare koppling mellan risken som ska försäkras bort och försäkringens användande. Frågan som behandlas i denna uppsats är huruvida sjukförsäkringens uppgift att hantera risk för inkomstbortfall på grund av ohälsa samt att omfördela resurser mellan högrisk ? och lågriskindivider kan utföras mer effektivt och försäkringsmässigt på en konkurrensmarknad än med en enhetlig sjukförsäkring.
