Antinutritionella substanser iåkerböna, ärter och blålupin vidutfodring till mjölkkor

There is a shortage of locally produced high quality protein concentrates in Europe andSweden. Local production would decrease the dependency on imported soybean and meet thedemand for organically grown feedstuff from ecological dairy farmers. Field bean (Viciafaba), peas (Pisum sativum) and sweet lupin (Lupinus angustifolius) are good alternatives tosoybean, but contain anti-nutritional substances (ANS) that could reduce their use as proteinconcentrates in dairy cow diets. The aim of this literature study was to review which ANSfield bean, peas and sweet lupin contain and whether they affect dairy cows negatively.Trypsin inhibitors and Chymotrypsin inhibitors (TI) were present in all three crops. TI couldbecome inactivated and degraded in the rumen, but due to the high passage speed of thedigesta, most TI left the rumen in an active state.

Koll på kollokationer : Om det bortglömda begreppet kollokationer i engelskundervisningen i den svenska skolan

The background to this study is that the field within language education known as collocations is being lost to students. The overall aim of this study was to examine what view foreign language teachers had on the field and how they taught it to their students. This study therefore conducted a survey to compare sentences consisting of wrongly used collocations with other common mistakes that students make. It also conducted interviews on how collocations was seen and taught in school by language teachers. 34 informants answered the survey and four teachers were interviewed to further investigate how collocations were presented to the students.

Luftprovtagning samt analys av mono- och diisocyanater

When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.

Riskbilder och kontroll av ungas IKT-användning: En fallstudie

The use of Internet by children and teenagers has become a special field of interest. Certain risks are associated with young peoples use of this media and national and international measures have been taken to assess and counter these risks.Library and informationscience have approached the subject of risks by looking at different software´s, so called Internet filters, that is used to control and censor the access to Internet based resources. In the USA, where public services and institutions that provide Internet resources to children and youth have started to require censorship of the Internet, a debate has arisen concerning the use of so called Internet filters.The theoretical basis of this master´s thesis is related to the conception of risk, gender and childhood. The focus of the paper lies on young peoples use of information and communication technology (ICT) and how risks associated with young peoples use of the Internet is constructed by different parties involved in supplying Internet resources. By means of a case study at a primary school in Skåne and at the company Netscan in Malmö.

Hur påverkar byggnadsmaterial av stål en induktiv hörslingas fältstyrka samt frekvensgång?

This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..

Hänsyn till mark och vatten vid slutavverkning : en fältstudie på känsliga marker

The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines. This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments. The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done. The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..

Meritpoäng eller skoj? : en undersökning om meritpoängens konsekvenser för ämnet moderna språk och framtiden

The main purpose of this C-essay is to answer the question: What have been the consequences and effects of the merit point system on language studies and the parties concerned (teachers, students and principals) during the school year of 2010/11?The merit point system is the result of a political decision and was implicated for the first time in the Swedish upper secondary school during the school year 2010/2011. Being a completely new phenomenon it is of great interest and importance to study its effects.The study in this essay also aims to verify, falsify or nullify two hypotheses very often referred to in the political discussions regarding the merit point system:The merit point system will replace affection and interest as main reasons for language studies in upper secondary school and cause a rectification amongst the students choices of additional courses.The merit point system will have a segregating effect upon society and make it harder for people to rise in society through education in the future.A verification of these hypotheses would imply the appearance of an increased rectification amongst students as well as an orientation towards an in the future more segregated society.The empiric material has been collected and examined with qualitative as well as quantitative methods (questionnaires and interviews) and belongs epistemologically to the phenomenological and hermeneutical traditions..

Svensk Kod för Bolagsstyrning : En förtroendeskapande åtgärd?

After a series of corporate scandals around the world the trust in the business world was damaged, probably most in the United States but also in Sweden. Voices were raised for an increase in the openness and insight into the affairs of the company whereupon different corporate governance codes were developed in a majority of countries. A Swedish corporate governance code was issued in December 2004 with the purpose to re-establish the damaged trust for the companies and the business world. The Swedish code was accepted by the Stockholm Stock Exchange as an exchange rule for A-listed and larger O-listed companies as of July 2005. The purpose of this essay is to study how the Swedish corporate governance code in fact leads to an increase in trust in the stock market and to study the companies? attitudes towards this code.To fulfil the purpose of this essay, the authors have carried out a survey among the concerned companies where the companies? attitudes towards the Swedish code were collected.

Reflekteras det nya insatsförsvaret i utbildningen till officer? : En komparativ studie av det militärhistoriska ämnets kursplaner och inriktning i krigsvetenskap på Försvarshögskolan och West Point

This paper examines whether the American officer?s education at West Point and the Swedish officer?s education at the Military Academy Karlberg have adapted their history of the military art education in accordance to the new requirements of the Armed Forces and its focus on the operational defense. Sweden is evolving towards an operational defense and so is the United States. This in turn requires that training and education keep up with the changes. The National Defense College in Sweden do not focus the teaching of advanced history, which happened beforet he invention of the engine, in the officer?s training program, while the American education is rather advanced, with special focus on events taken place in the 19th century up to the Cold War.

Utveckling av styrning till solföljande MaReCo-hybrid i Hammarby Sjöstad

Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

Interkommunal IT-samverkan. Faktorer och effekter av ett framgångsrikt samarbete

Today more and more municipalities interact across a wide range of sectors. The reasons tostart interacting are varying and for those who succeed with this form of work, there arebenefits in terms of efficiency and knowledge exchanges. But are the reasons that interactalways obvious? Sweden currently has 290 municipalities of varying size and allmunicipalities have basically the same mission, to deliver services to its residents.Information technology allows municipalities to digitize much of the workload, but theintroduction of the technique is not without problems. For small municipalities, there are greatdemands to deliver reliability and support for their internal and external services.

Sönderdelning av plogtilta med skärknivar :

During the last couple of years it has been more important to reduce the driving on the field to prepair the soil after ploughing. The machine costs are high so it is necessary to be effective. To reach a pleasant soilbed directly after ploughing is sometimes possible on easier soils but heavier clay soils always need more tillages. There is a lot of equipment mounted on the ploughs on the market, for example Furrow Cracker and Furrow presses, which makes a pleasant soilbed on easier soils. The last year Överum and Kverneland have presented knives which are mounted on the wing or moulboard.

Ekot från djupaste Afrika : En kritisk diskursanalys av nyhetsprogrammet Ekots gestaltning av konflikten i Goma, Demokratiska Republiken Kongo.

This is a critical discourse analysis of the conformation of the conflict in Goma, Democratic Republic of the Congo, as constructed by Ekot, a news-show on Radio Sweden. The ambition of this bachelor thesis is to examine the production of a Congolese conflict for a Swedish audience and to find out how the construction differences with and without a reporter in the field. To obtain this purpose the narrative is studied as well as the use of voices that define the conflict. The construction of proximity between Swedish audience and the Congolese event and the meaning of sound to stabilize the formation of discourse within foreign news is examined as well. To conform and explain foreign news it must be put in relation to a starting point.

Evaluation of transgenic lines of field pepperweed (Lepidium campestre L.)

The worldwide industrial demand of energy, often in form of fossil fuel, is continuously growing and at the same time these resources are coming to an end (Hamamre, 2013). The interest and focus in renewable sources are then more important than ever and plants are suggested to be a good alternative for production of raw material for industrial purposes (Nilsson et al., 1998). But the world is also facing an increasing world population which also increase the nutritional needs, plants therefore need to be suitable for both industrial and nutritional purposes. To achieve this, common plants need to be improved but it also need new potential crops to be developed and introduced (Carlsson et al., 2009). Modern technology like gene engineering is an important tool to achieve these challenges (Carlsson et al., 2011). This work focused on analyzes and evaluation of different transgenic lines of field pepperweed (Lepidium campestre L.).
