Towards sustainable rye cultivation : soil carbon and yield modelling for crop rotations with rye

Using the Introductory Carbon Balance Model, ICBM, five different crop rotations with rye 1. Rye-Ley-Ley-Rye-Beans-Rye 2. Rye-Rye-Rapeseed-Rapeseed 3. Rye-Ley-Ley-Rye-Potatoes-Rye 4. Rye-Rye-Potatoes-Wheat 5. Rye-Rye-Potatoes-Beans-Wheat-Rye-Potatoes-Rapeseed were tested theoretically in four different cultivation scenarios ? Straw left on the field, biogas digestate added as fertilizer. Labelled ?+straw+BD?. ? Straw left on the field, only synthetic fertilizer. Labelled ?+straw-BD?. ? Straw harvested, biogas digestate added as fertilizer.

Dragbrotschning av invändiga profiler

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

IKT - 2000-talets mentor? : En jämförande studie mellan manliga och kvinnliga pedagogers uppfattning om IKT i undervisningen

During the past decade Information Technology (IT) and Information and Communication Technology (ICT) have become the main tools in teaching. Authors and early educators who are treated in the study talks about how technology has come to change the school's approach to teaching and didactic tools. The technology has also affected students´ and teachers´ ways to work because the technology's versatility makes demands on the user's expertise and competence. The technical skills have long been associated as a male domain, where men are expected to master the technology´s versatility. These expectations are not the same for women.

Uppföljning och analys av Stockholms stads solcellsanläggningar

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

Redovisningskonsekvenser vid förändringen av pensionsredovisningen

AbstractAuthors:Stefan Harrå and Magnus BjörkAdvisor: Markku PenttinenTitle: Accounting Consequences of the change in pension accounting Background to problem: When the revised IAS 19 comes into force January 1, 2013, it means that two of the three accounting principles for defined benefit pension plans are disappearing, including the corridor method. The corridor method has made it possible for companies to defer its actuarial gains and losses. Now that the corridor approach abolished then the unrecognized actuarial gains and losses immediately be covered by equity, which involves very large amounts of some companies. Why the amounts have grown so big is much because of the discount rate. The discount rate is a controversial parameter, and there is disagreement on how it should be fixed.Purpose: The purpose of this thesis is to examine the accounting implications this will have for the company applied the corridor method, and if there is some parameters in the actuarial assumption that is more important than others.Methodology: The thesis has mainly been based on a qualitative research through qualitative interviews with a small sample that is affected by this change.

Konfigurationshanteringsverktyg (CM-verktyg) och CM-kriterier, dess tillämpning för presentation av migreringsdata

The purpose of this thesis is to present and describe which criteria, according to the systemfamily Configuration Management, should be met when developing a CM-tool to handlemigration data.ACT is a tool developed by Microsoft to gather information about, analyze, test and mitigateapplications in a network when migrating the IT-infrastructure of an organization to a newoperating system. The organization that is being studied wants to present the data about theanalyzed applications in such a way, that a customer can choose what to mitigate and migrate.The goal is therefore to develop a prototype (CM-tool) that will present this data.The study has shown that ACT lacks certain requirements stated by the organization when itcomes to presentation. But when it comes to the rest of the functions, ACT performs as expected.The investigation resulted in specifications and technical solution for the new CM-tool. CMcriteriafor migration data was put forth and parts of the prototype were also developed..

Betavärdet som mått på systematisk risk inom aktievärdering

The beta value is frequently described in theory and is a well known factor to quantify the systematic risk in shares through the CAPM model. Initially, this study describes the advantages and difficulties with the estimating process and the problematic nature of the assumptions and descisons included in published beta values.An alternative method, Bottom-up beta, to estimate the beta value that probably has not been tested under Swedish circumstances is applied. The problems and decisions that have to be made to derive an alternative value are studied in detail through six separate steps. I have chosen nine companies at the Stockholm Stock Exchange where this method is used. The result showed that the systematic risk were higher at five shares and lower at four, compared to the published values.Finally there is a discussion about the practise, usefulness and opinions concerning how to estimate and interpret the beta value to determine the expected return..

Gränsdragningsproblemet i luck egalitarianism

The purpose of my study is to investigate whether luck egalitarianism can be savedfrom its inability to draw a line between risks which can reasonably be expected to beavoided, and risk which can not. Such a demarcation is of particular importance forthis influential theory of distributive justice, since it serves to judge whether a personis entitled to compensation for a bad outcome of a taken risk, or not. Testing theintuitiveness and coherence of various contending principles for how to separateavoidable risks from unavoidable ones, I conclude that luck egalitarianism seemsunable to draw a clear line between the two kinds of risks. Instead the theory appearsto be dependent on conceptions of a 'normal life', making it remarkably vague.Furthermore, I argue that luck egalitarianism seems unable to manage without takingsufficientarian and utilitarian concerns into account, for the purpose of decidingwhich risks are avoidable, and which are not..

Analysmodellen - en variation i tillämpningen?

The purpose of our essay is to examine if variation exists in the way that auditors try their independence, this so called analysis-model. We will suggest some factors that influence the way auditors practise the analysis-model. The institutional theory predicts no differencies since the normative pressure could be expected to be severe. But we found that among other things people?s qualifications, personalities and audit firm?s size and age influence the way auditors try their independence.

Konstruktion av upprätningssystem för CICLoPE

Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.

Gymnasieskolan i förändring - hur väl anpassade är skolbiblioteken?

The general view of learning has dramatically changed during the last two decades. Today we talk about learning for life and educate to meet the demands of the information society. This new view forces us to constantly relearn and develop new knowledge ? something which has resulted in large restructuring within the upper secondary school. New forms of teaching, where the pupils are given the opportunity to a more active search for knowledge, is developing.

Methane production from dairy cows : relations between enteric production and production from faeces and urine

Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.

Lyckans land? : En ekonometrisk studie över nationshemvistens påverkan på upplevd lycka.

Does the country people live in affect the probability of them experiencing happiness? Can a country variable in an ordinal regression model be affected when microeconomic and macroeconomic factors are added to the model? The possible outcomes are either that the country variable affects less when the additional predictors are added to the model, or that they stay the same. The micro data is collected from the European Social Survey database, the macro data is collected from the World Bank. The country variable becomes less substantial when additional variables are added to the model. The variable with the most influence over expected happiness apart from the country variable is whether the individual often socializes with friends or not.

Kollektiv kollaps i ett handbollslag på elitnivå: en studie med fokus på emotionell smitta

Collective collapse occurs when a majority of players in a team suddenly perform below expected level in a match of great, often decisive, importance in spite of a normal or good start of the match or when a team underperforms right from the start of the match. The aim of this study is to investigate collective collapse, focusing on emotional contagion. The study is a qualitative study based on semistructured interviews with nine handball players in an elite team. The results show six factors presented as themes. These are Preparations, The coach and leadership, Emotional contagion, Communication, Role Acceptance and Incongurence.
