Controlled traffic for grass silage production : an economic evaluation for dairy farmers

The farm management system controlled traffic farming (CTF) aims to reduce soil compaction by restricting the field traffic from agricultural machinery to permanent traffic lanes. Literature and empirical findings show that soil compaction and field traffic from heavy machinery may affect crop growth negatively, reducing crop yields. If grass-clover leys are subject to heavy field traffic the botanic composition might be altered, providing a lower clover content in the forage. Clover as a silage feed is rich in protein providing good conditions for high yielding dairy cows. Grass-clover silage production is generally associated with intensive field traffic.

Praktisk tillämpning av Lean Production : En möjlig väg till minskat slöseri

Utländsk arbetskraft konkurrerar allt mer om arbetstillfällen i form av lägre löner och produktionskostnader. Detta gäller inte minst inom bygg- och anläggningsbranschen. Ett sätt att effektivt minska kostnader är att undersöka hur eventuellt slöseri kan undvikas. En filosofi som fokuserar på detta är Lean Production som allt fler företag i bygg- och anläggnings-branschen försöker arbeta enligt. Svensk Markentreprenad AB är ett ungt, växande företag som strävar efter att arbeta effektivare.

Från ?hög och fin? till ?se upp på Gerrard? : En kvalitativ textanalys med fokus på förändring i TV-fotbollsgenren

Abstract Our intent with this study was to find out what changes have been made during the last 30 years in the way that the media reports from certain events. We choose to study the world of football and specially the Swedish national team and it?s relationship to the Swedish television medium in the World Cup of 1974 and the World Cup of 2006. The study mainly focuses on the differences in commentary and in the production from both of the championships. We used Keith Selby and Ron Cowdery?s book How to study television and Mats Ekström and Lars-Åke Larsson?s book Metoder i kommunikationsvetenskap as tools to analyze the games we watched. The result showed that there?s been a lot of changes media wise between the two championships.

BNP och hushållsproduktion : En jämförande fallstudie av Sverige, Tyskland, Estland och Finland baserad på satelliträkenskaper för hushållsproduktion

This document presents calculations of adjusted GDP based on satellite household accounts for the year 2001 with the purpose to compare adjusted and official GDP for Sweden, Germany, Estonia and Finland. Household production in each country is estimated using time use survey data from Eurostat and a monetary value is estimated using average wage (after taxes) for each country. The results indicate that the value of household production using this methodology increases GDP with between 42% (Finland) and 55% (Germany) compared to official GDP statistics. A comparison of GDP/capita between the countries included in the study shows that the GDP/capita in Germany increases more that the other countries due to the relatively high proportion of time used for household production (mainly German women) combined with a high average wage. In fact, the results show that Germany has higher adjusted GDP/capita than both Finland and Sweden (but Germany has lower GDP per capita when official statistics is used for the comparison).

Liquid diesel biofuel production in Sweden : a study of producers using forestry- or agricultural sector feedstock

The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

Tidsupplösning vid miljövärdering av fjärrvärme : Kontorsbyggnad med solvärmeproduktion - en fallstudie

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

En exakt konst: : (Re)produktion och gestaltning av makt och normalitet genom mat och måltider i Virginia Woolfs Mot fyren

The aim of this essay is to analyze how food and meals produce and reproduce values and power relations and how these processes are portrayed in Virginia Woolf?s To the Lighthouse. Using sociological writings in the field of food consumption and production I study the structures that affect our relation to food and eating. This perspective is combined with a phenomenological view, aiming to examine how food is perceived, which is also inspired by queer theories. Using the method of close reading, the theories are applied to Woolf?s work.

Lönsam produktion av stärkelsepotatis : timing och skördeanpassade åtgärder

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.

Simuleringsmodell över Ålö AB

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.

Förändringsarbete mot en resurssnål tillverkning : Lean production i ett svenskt tillverkande företag

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.

Skogs påverkan på vindkraftsproduktion - en fallstudie av vindkraftverk vid Andersfält.

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..

Livscykelanalys av sex olika fiskodlingssystem : Fiskens miljöpåverkan för konsumtion i Stockholm

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.
