Cultivable land is a limited resource and agriculture contributes to some of the most serious environmental problems facing the planet like, global warming, eutrophication and loss of biodiversity. The specialized, industrial agriculture with monoculture and extensive input of external energy, commercial fertilizer, and chemical pesticides are all essentially unsustainable. An adaptation to other methods of production is necessary to preserve the environment for future generations. The aim of this study is to describe the factors that distinguish sustainable from unsustainable agriculture. The results will be used to examine if and how the European Union (EU) works in order to create a more sustainable agricultural industry and to analyze the preconditions for such development.

This thesis is based upon the work done at Westinghouse electric company (WEC)inVästerås during the spring semester of 2015 and describes the development of a quickcoupler with associated blade changing tool. These are meant to be used togetherwith a sawing tool that the company uses for the dismantling of nuclear reactors,which is performed under water.The aim of the thesis was to develop a complete manufacturing documentation withdrawings and related CAD models which Westinghouse later can use to manufacturethe tool and the quick coupler. It was also included in the assignment to, if necessary,modify parts of the saw tool to adapt these to the intended blade changing tool.A number of visits to the company's workshop was made during the time to study thesaw that the thesis is based upon. The purpose of these visits was to get a better ideaof the dimensions, construction and the field of use of the saw. On three of thoseoccasions various engineers and consultants accompanied us to discuss possibleproblems with different ideas.This was interspersed with information in the form of literature studies on quickcouplers to create a clearer picture of the nature of the task.When enough information had been gathered a functional analysis was made to dividethe main problem into subthis phase the idea and concept generating process took place.The methods used for this was mainly brain writing and brainstorming.

Barn med Down syndrom (DS) har problem med hypotonus och hyposensitivitet som begränsar rörligheten i ansiktets och munnens muskulatur, vilket därmed försvårar tal och sväljning. Målet med en intra- och extraoralsensorisk behandling är att öka medvetenheten och kontrollen av munnens muskulatur, dess rörelser, spänning och känsel.  Syfte med föreliggande studie var att undersöka effekten av en intra- och extraoralsensorisk intensivbehandling med eltandborste hos en grupp barn med DS och hypotonus. Effekten valdes att studeras utifrån områdena orofacial funktion, läppslutning, talproduktion och oralsensorik. Nio barn i åldrarna 6 till 12 år genomgick behandlingen med fyra behandlingstillfällen i veckan under fyra veckor.

During year 2004 Ålö AB made significant change in their production process. The production of front loaders is nowadays highly automated with short operation times. To be able to control their process in a better way Ålö recently decided that they needed a tool for simulation of their production and to shift patterns. This final thesis started with a pilot study in Ålö?s factory in Brännland.

The European Union has been working to promote equality between women and men for a long time. Despite this, Sweden still have a gender segregated labor market where men generally has the leading positions. According to European law the member states shall promote gender equality and to take all appropriate measures. Statutory gender quotas for company boards is one such measure that some of the European member states have implemented in national law. The Swedish law has no provisions governing gender quotas and therefore the purpose of this study is to explain how gender quotas for company boards relate to current law, both of European law and national legislation.

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

It is about the patriarchal power structure which we are living under and so have done in hundreds of years. And about to (dare) see, because it can take fairly subtle expressions which is rather difficult to discover if you are not aware about them. This paper is about these power strutures seen from the daily round of four girls which study nurse´s training in upper secondary school and four girls which study construction´s training in upper secondary school..

Vilken strategi ett tillverkande företag arbetar efter kan variera och bero på en mängd olika faktorer. En effektiv tillverkning kan bli komplicerad när marknaden efterfrågar allt mer skräddarsydda produkter med varierande egenskaper. För att bemöta denna typ av komplexitet finns en rad strategier och modeller som har fått global spridning. En av dessa strategier är lean production, ett begrepp som vuxit fram utifrån studier genomförda på den japanska tillverkningsindustrin.I denna studie undersöktes varför lean production valdes som styrningsfilosofi i ett svenskt tillverkande företag, vilka förändringar detta inneburit samt vilka åsikter som fanns kring förändringsarbetet. Insamling av empiri har skett genom att genomföra en fallstudie på företaget Trioplast Sifab.

The purpose of this study is to investigate how the legal protection against sexual harassment at work functions, and where to draw the line. The study is limited to focus on the sexual harassment directed at women from men, because it usually occurs that way even though only a few report the incidents. The results are discussed from a gender perspective on how the distribution of power is between men and women as a way to explain sexual harassment.Sexual harassment is currently protected by the discrimination law and the EU principle of equal treatment for men and women. For a behavior to be considered as sexual harassment it has to be unwanted by the receiving party and the person practicing the harassments must be aware that the behavior is perceived as offensive. The behavior shall be of a sexual nature and contribute to a disadvantage for the victim in the form of a violation of that persons integrity.It is the victim that determines whether the behavior is perceived as sexual harassment or not, what one person believes is a friendly behavior may be perceived as offensive by another.

The French historian Marc Bloch is considered to be one of the masters of medieval history, particularly his creation Feudal Society has been an essential piece of work for everyone who desires a deeper understanding of the general feudal society. Bloch gives his readers a vivid and living picture of a society so far beyond our present that it is sometimes hard to keep in mind that this society is part of our legacy. At the same time Bloch endows his readers with the special historical outlook he and his successors has developed, the history of the mentalities. By reaching further back in time, to the Roman and Germanic cultures and the manorial system, he proves his point that the feudal society was build on the legacy of older structures and institutions.In the coming study I will disentangle the early feudal structure of power as Bloch has described it in his Feudal Society. The essence of this power structure is to find in the very characteristic tie between two men, the vassalage.

The purpose of this master thesis is to investigate how nearby forests affect the energy production in wind turbines. To reach the purpose a case study is performed on three wind turbines sited on a field in a north-south line at Andersfält in the municipality of Halmstad, Sweden. Approximately 100 meters south of the southern wind turbine a forest is situated. The case study is divided into three sub studies where the difference in energy production, the affect of the forest and a wind meteorology model, WAsP, is studied. The result show that the forest have a significant influence and that the WAsP-model gives an incorrect result of the energy production in wind turbines sited near a forest..

The purpose of this essay is to analyse how medial representations in a specific cultural debate expresses thoughts about gender, power and speech. The debate in question took place in Sweden 2010 and was about an inspection of sexual harassments in the Swedish acting area, made by Sveriges Radio, Ekot. This essay examines the made representations of the debate, with a feministic point of view and concludes that a male gaze shapes the form of speech and gives the debate a discourse sort of reasoning about gender. The special discourse formatted in the examined area contains a certain conception of power and the structure of power, which is also explained by the male gaze and the meaning of post-feminism..

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

Our purpose in this paper is to examine if there is any profitability for a company with a factory in the timber industry to invest in a combined heat and power, CHP. Based on analysis and the results that the paper generates, we will give Derome AB a suggestion on how it is a profitable investment or not to installing in a CHP.By investing in a CHP plant, you can get a high efficiency, which means that companies can use their resources more effectively. The Swedish wood industry has by-products of production that can be used for combustion in their boiler which is an advantage.The essay is a qualitative study where we have a case company, Derome AB. In this company, we interviewed two employees who have knowledge in the study. They have helped us to provide information and data about their business.We chose to use the pay-off- and the net present value method, NPV, to see if there are profitable advantages for the investment.

During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.
