Large amounts of phosphorus (P) are lost from the arable land due to water erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses. In this study, soils from 50 fields were analysed with respect to aggregate stability as measured by dispersion of clay together with the content of total phosphorus (TotP), particulate phosphorus (PP) and phosphate phosphorus (PO4P) in the water phase. All soils were clay soils with clay content varying between 21 and 54%.

Orust Kretsloppsakademi is a nonprofit organisation, with a goal of annually generate the same amount of electrical energy that is consumed. Orust is an island on the west coast of Sweden, north of Gothenburg. The population of 15 000 reaches 40 000 during summer, due to the large amount of vacationer. The total electricity demand is 174 GWh a year with a maximum power need of 32 MW. This report presents an analysis for the plausibility of their plan and from a power system stability perspective, the effects on the electrical grid.The conclusion is that the restraints for development of power generation from wind, solar and wave generation, are the power systems capability to transfer power, primarily in the transformers of the grid.

The aim of this thesis is to evaluate a Swedish subject headings list for childrens and young adults fiction, from the perspective of consistency, and to analyze this concept's importance as a tool for measuring indexing quality. Another aim is to examine how librarians view the subject headings list as an aid for indexing fiction. The main questions are: How does the degree of consistency change when using a subject headings list for indexing fiction compared to free indexing? How does indexing change according to the facets Form/Genre, Time, Space, Matter and Person when using the list? What do consistency calculations reveal about indexing quality? How do the participants look upon the list as an aid for indexing? The empirical material consists of results from two different indexings of fiction, conducted by librarians. Consistency is calculated using Hoopers and Rollings algorithms.

This report will point out the income for a scania plant production farm, this has been estimated through a case study. The outcome of this report will later be used to calculate a reasonable leasehold charge. This case study is solitary based upon this particular studied farm, at this very point, and can therefore not be used as a general guide. The reason why this particular scania plant production farm has been selected, is because the author is born and raised at the farm and has the intention to run the farm in the future. The chosen farm for this report is based in the southwest of scania and cover 300 hectare of plant production. The crop rotation consists of autumn wheat, sugar beats, spring wheat, spring barely, winter rape and fallow. The farm owns all machinery required.

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

System based models of plants rely on descriptions and assigned functions of genes, and currently 50% of the genes in Arabidopsis thaliana has either no assigned function or a function based on homology only. Mitogen activated protein kinases (MAPK's) are key players in cell signalling and are conserved among eukaryotes, though their targets are highly diverse. A recent study has described a small Arabidopsis protein (80), without homology to any described protein, as a phosphorylation target of the MAPK's MPK3/6. Further work established ?-glucan phosphorylase (PHS) as interacting with 80 and described a delayed senescence phenotype for 80 knock-out plants.

The vertical electronic excitation energies for the narrow-bandgap polymers LBPF, EP37 and EP62 have been calculated using Density Functional Theory (DFT). Also the vertical excitation energies for the acceptor unit of LBPF have been calculated using the Hartree-Fock (HF), DFT and Coupled Cluster (CC) methods. The calculations cover the visible and infrared wave length region and two strong transitions are obtained, one corresponding to the pi to pi* transition and one corresponding to the pi to Acceptor transition. The excitation energies obtained from DFT are below the corresponding experimental results and attempts have therefore been made to perform bench-marking calculations using a hierarchy of CC methods..

This study treats the possibility of breeding mallards and pheasants on our own farm, Björnslund. From the beginning I considered to breed them from eggs to adults but after visiting several breeders I changed my mind. It seemed to be a lot of work with no economic profit in comparison with buying already hatched birds and then feed them to adults. If the business shall be profitable I have to be soll the hunting for the birds and then sell the dead birds to game purchasers. There are also calculations that show which price you have to charge for the hunting that will give a positive result. Another possibility is to own a slaughterhouse and sell the meat to restaurants and supermarkets.

The avowed aim in this project was to see how the Swedish egg production is today. My first question was if the Swedish egg producers egg production turn a profit. I have done five after calculation at five different egg producers with different systems from case to case. The difference has been the living system, the fodder and the egg price. They made a report in Uppsala, Sweden (Hoffman & Andersson, 1996), where the look forward to a Swedish cage ban and made calculations after that coming ban. After that they lift the Swedish ban of cages and the egg producers could invest in new cages who called the decorated cage.

The regulatory framework for constructional calculations in Sweden did expire In January the 1.st, 2011.Since then the constructional regulatory that originally were composed by Boverket (BKR) has been replaced by new common range (Eurocodes) for the entire European Union. This transition has led to changes in existing rules and standards regarding dimensioning area in Grids and has forced a need for updating to structural Engineers.The new calculation system has caused time-consuming studies of the new rules and a proper understanding of all the advice and regulations for the entire profession.This study has been carried out in cooperation with the firm "Knut Jönson Ingenjörs AB i Stockholm?, that has been affected by this transition as all other consulting firms. The firm has requested for a calculation method of wall beams according to Eurocodes. The study's focus is therefore to clarify the rules and guidelines regarding the design of wall beams according to the new regulation.

This thesis aims at determining the heat losses in a property vent stack and its roof valve. Upon request of a company, the vent stack is analysed for possible heat recovering solutions to be implemented, while relining of the drain system is executed and with a suitable payback time for the economic investments. The heat loss calculations are based on data for properties that are located in the Stockholm region, but also easy to change depending on the situation. The calculations are done on pipes made out of cast iron, which still is the most common type of drain pipe in Sweden, and these are the pipes that relining is usually made on. The calculations that needed to take several variables into account have been done in MatlabR2014a and the thermos dynamical properties that were used in those calculations have been extracted from EES.Three different types of heat losses in the vent stack have been taken into consideration in this thesis.

At Volvo Cars Torslanda's paint shop there is a requirement to in a fast and effective way get an overview of the plants capacity. Therefore a capacity template was constructed as a tool for the engineers at Volvo several years ago. This template has during the years become complicated and outdated. Thus this thesis work will resort as a new capacity template, built from scratch. The new template has been built up based on requirements from Volvo and the concept of OEE (Overall Equipment Effectiveness).

Our employer Camatec Industriteknik AB gave us the assignments to increase theirs range of versions on Camcoil that is their own patent product. Camcoil is a capstan system that is used when steel band fabricated. Exist for example in production lines their steel band should be annealed. Our goal with this work is to come up with a completed production basis on a Camcoil for heavy industry. The basis should contain calculations, 3D-constructions, drawings and cost proposal on manufacturing and detail purchase.Demands on this project:1.

This project was conducted on behalf of the organization SABO (Swedish Association of Public Housing Companies). The aim of this project was to investigate which relevant environmental aspects and indicators there are for housing companies to present in their sustainability report. The project consists of three main goals: to decide if there is a need for common guidelines when conducting a sustainability report, determine appropriate environmental indicators and to create a simple model of how the companies can present them. This was done by a literature study, analysis of 13 sustainability reports and interviews with seven housing companies. The result of the project suggests that there is a need for common guidelines to, among other things, make it easier to make a comparison with other companies.

This thesis is about Christmas tree plantations in Sweden, and if its profitable to produce Christmas trees in Sweden. Sweden has 4,3 million households, 3 million of these households buys Christmas trees. 80 % of these Christmas trees are Norway Spruce (Picea abies), which is the most common Spruce in Sweden. Every year over 170 000 Christmas trees are imported to Sweden. The main import comes from Denmark.
