Tankar om plöjningsfri odling :
The margin in crop production is more and more less and it forces the producer to check
out how to reduce the cost of establishment of new crop. One way to reduce the cost in
establishment is to begin with plough less farming. It saves money and time compares to
conventional soil preparation with plough and harrow.
Not all soil types are god for plough less farming and should be continued with
ploughing (mainly light soil), but other soil types working very well with plough free
farming.
If you want to success with plough less farming you have to think in new lanes. One of
the things you have to think about is to not grow too much cereal after cereal. Low
stubble is important when you harvest the crop and also to spread and chop the straw
well.
I have in this work interviewed some farmers and farm advisers in Östergötland to see
which thoughts they have about plough less farming.
A resource based view of productivity, firm growth and technical management tools : a case study of Swedish large-scale farms
The past and ongoing structural change in Swedish agriculture has led to an increasing
number of large-scale farms. The biological factors associated with large-scale farming
operations may cause increasing variability, risk and reduced yields due to sub-optimal timing
and management of field operations. The theory of economies of scale suggests that largescale
production may benefit from lower costs due to scale efficiencies. Thus, large-scale
farms may face cost reductions in terms of long term inputs factors, e.g. agricultural
machinery.
Snabbhet och precision hos det visuella korttidsminnet för randmönster och ovaler
Den här uppsatsen handlar om korttidsminnet (arbetsminnet) och dess kapacitet att lagra och processa information. Ett perceptionsexperiment som utfördes ger en inblick i hur korttidsminnet fungerar i praktiken och innefattar randmönster och ovaler som stimuli. Responstid och precision mäts och jämförs med avseende på betingelser som position och orientering. Uppsatsens hypotes är att samma respektive olika position på stimuli har betydelse för både snabbhet och precision. Resultatet bekräftade denna hypotes.
Avskogningen av Amazonas
Organic agriculture is financially promoted in Sweden by special environmental support and as consumers we are all encouraged to buy organic food. At the same time scholars at the Swedish University of Agricultural Sciences claim that organic farming does not provide any environmental benefits. The main criticism is that organic farming has lower yields than conventional, which means that more land is needed to produce the same amount of food as in conventional farming, leading to deforestation and loss of biodiversity. As for climate change, the critics claim that the significantly higher productivity in conventional crop production compared to organic, releases surplus land, which could be used for bio-fuel production and thereby replace the fossil fuels. The critics also claim that organic farming causes higher nutrient leaching than conventional.
Ask.com, Web Wombat och Yahoo: En studie av två globala och en lokal sökmotor.
This thesis is focusing on how global and local search engines retrieve information from the local domain. The three search engines tested are the global search engines Yahoo, Ask.com and the local search engine Web Wombat. The questions we examined were: which search engine has the best retrieval effectiveness? Could there be other reasons than retrieval effectiveness, to choosing a local search engine?For our test we constructed 20 questions related to Australia.We chose to divide the questions into topics like nature, sports and culture. For all questions we evaluated the relevance of the first 20 hits.
Inga miljövinster med ekologisk produktion? : Lägesrapport över den svenska jordbruksdebatten

Eu:s jordbrukspolitik sett ur perspektivet ekologisk hållbar utveckling i Sverige
The aim of this essay is to give the reader an idea of how the European agricultural policies have developed, in regard of sustainable development, since Sweden became a member in the union 1995. The main aspect that?s been investigated is the issues regarding sustainable development and how the issues regarding the ecological farming methods have been dealt with. My research questions are:- How has the European environment- and agricultural politics changed since Swedenjoined the union in 1995?- What consequences have the changes had for ecological farming?The answers to the stated questions are that there have been several treaties in the field of environmental development of the agricultural policy, starting with the Maastricht treaty and ends up with the European Action Plan for Organic Food and Farming.
Vad bidrar till valet av precision i produktkalkylen?: En fallstudie om diskrepansen mellan teori och praktik inom produktkalkylering
Studies show that activity based costing (ABC) is not widespread in practice even though it has been present in the academic world since the 80's. This thesis examines the reasons for the discrepancy between theory and practice through a case study of a Swedish manufacturing company. The intension is to answer the question of what contributes to the choice of precision in product costing.We found arguments for increasing precision in product costing but not to the extent of a full-scale ABC implementation. The company's estimation of the value of increased precision. In the study three company unique factors were isolated that affected the company's estimation of value; drifting purpose of product costing, historical use of product costing and knowledge about product costing..
The economic consequences of Striga hermonthica in maize production in Western Kenya
Kenya is a country of 35 million people and is situated in Eastern Africa. 70% of thepopulation works within the agricultural sector and for many of them food insecurity is amajor problem. Maize and beans are today the staple food for many households. Goodfarming conditions enable two harvests per year and a potential maize yield of 4-5 tons perhectare.A major problem for many farmers in this area is the increase of the weed striga. The weedcauses severe yield losses, and has a major economic impact on smallholders.
Evaluering av återvinningseffektiviteten i Svensk Medicin och Google Scholar med medicinska frågor ur Fråga doktorn.
The purpose of this thesis is to evaluate and compare the retrieval effectiveness of two search engines on the Internet: Svensk Medicin and Google Scholar. Svensk Medicin is a medicine-specific search engine and Google Scholar specialises in indexing scholarly material. A set of 20 questions in four categories were used to conduct the searches with the search engines. Genuine medical information needs were selected from a question collection provided by the television program Fråga doktorn. The relevance of the first 10 retrieved documents was judged by using a binary scale and the measure used was precision.
Google, Yahoo! och Live Search: en evaluering av tre webbsöktjänster
The purpose of this Master?s thesis is to evaluate three general query-based web search engines. The search engines chosen are Google, Yahoo! and Live Search. The topics, which where transformed into twenty queries, are based on real users? information needs, taken from an ask-a-question service.
En precisionsstudie av förstärkt verklighet som positioneringsverktyg
This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.
Är GPS-styrning lönsamt :
GPS is perhaps the future in agriculture. The next years will show it but the precision becomes only better and better and the number of users becomes only more and more. This work shows experiences from today's users and how the profitability can be improved on a farm with normal plant cultivation. The aim is to show how big the actual advantage can be to have a GPS and how good precision there is with the equipment. John Deere and Trimble are the big producers of GPS equipment to the agriculture.
Barriers to convert to organic farming and the role of risk : an empirical application on Swedish data
To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.
Förbättrad precision vid ankomstkontroll
Examensarbetet utfördes på Balco AB i Växjö, som tillverkar och erbjuder balkongsystem påtotalentreprenad. Eftersom Balcos ökade omsättning har lett till att ankomstrollen inte längre kan utföras medtillräckligt hög precision, så har produktionsplaneringen blivit lidande. Syftet med projektet var därför att Balcoska kunna ankomstrapportera inkomna aluminiumprofiler från underleverantörer på ett smidigt sätt, samt medhög precision.För att lösa Balcos problem vid ankomstkontrollen, så att de enkelt kan rapportera in och få en god översiktav ankommit gods, har projektgruppen kommit fram till tre olika alternativa lösningar. Dessa lösningar ärstreckkodssystem, RFID-system och manuell identifiering. För bästa resultat, och användning avidentifikationssystemen, är det troligtvis nödvändigt att ett MPS-system implementeras.Slutsatsen och rekommendationerna innefattas främst av en lösning med ett streckkodssystem, men där denprimära nyckeln till ökad precision och kontroll av ankommande gods ligger i att införa ett väl fungerandedatasystem..
