Skydd mot yterosion i slänter av finmorän
Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.
Brikettillverkning på gårdsnivå :
In my work I have chosen to examine the profitability for small scale production of hemp briquettes. My study also includes a review of which briquette technique that is the most common one among small scale producers. The reason that I have chosen this subject is because of the discussions about climate and energy that we face almost every day. I also think the subject is extra interesting in these days when the Grain prizes are at a historic high level.
In order for me to achieve a reliable report, a hemp and briquette producer has given me the actual data from his farm. In that way I have been able to make my calculations from a concrete perspective.
Utdragshållfasthet hos limmade och olimmade gängstänger i limträ
This essay examines pull-out strength of threaded rods fixed into glulam timber. The technology is intended to be used in hidden joints between glulam components. The work began with a study of literature focusing on current research within the topic, mainly to create a base of knowledge before the testing was initiated. Studies of scientific articles reveals a lack of research within this area, which makes it difficult to develop standards and calculation models for these joints. The drill holes in the tests have a diameter of 7 mm.
Geotermi i Ungern : Undersökning av Ungerns energisituation inriktat på geotermi samt kapacitetsfaktorn för det största geotermiska värmeverket i Mellaneuropa.
Hungary?s share of renewable energy in 2010 was 7.9 %, and their renewable energy goal for 2020 is 14.65 %. Geothermal energy is one option that could help to achieve the goal, since Hungary has favorable bedrock, the temperature gradient is above average and thepermeability is high. Today Hungary is importing just over half of its primary energy supply. Because of political conflicts between nations Hungary wants to expand its own production of energy.
Etablering av höstvete med reducerad jordbearbetning :
The payment for produced Grain is constantly going down in price. It is important for farmers to become more effective in cultivating more land in a shorter time perspective. At the same time we have to calculate with the risk of getting lowered subsidies from the EU. This is why I would like to find out the possibilities for establishing winter wheat without ploughing.
I hope to find a difference in the number of plants due to different soil preparations. With this experiment I expect to find out whether I can establish winter wheat at a lower cost, with the same numbers of plants per square meter.
Propionsyratillsats vid gastät lagring av spannmål
Kostnader för lagring av spannmål till djurfoder är en viktig parameter för lantbrukare som lagrar sin hemmaproducerade foderspannmål. Därför är det viktigt att hitta ett smidigt system med god säkerhet gällande hygienisk kvalitet och lagringsduglighet. I Sverige har vi ofta förhållande med spannmål som håller vattenhalter över 17% efter skörd, vilket i många fall leder till att spannmålen måste torkas. Torkningen är en dyr men säker metod. Med hjälp av Grain Bagger Mainero 2230 kan man lägga in spannmål snabbt och effektivt i en syretät slang.
Produktionskalkyler för biobränslen :
This study is one of five that has been done based on Lunds Energi?s planned investment
in bioenergy. The plan is to build two large burners, at Örtofta, that?s going to be
supplied with biofuels.
In this study I take a closer look on the profitability when you choose to sell your cereal as bioenergy. I?ve been calculating with selling the straw from the Grain crops and winter rape, selling the rye weat as whole crop and fertilize the hemp with sewage
sludge.
Villa Furulid : gamla anor möter dagens behov
The last years? financial situation has contributed to an increased willingness from the banks to handle risks. The most important risk to cope with is a risk that is related to a customer?s ability to repay loans. Forecasts indicate that in the future, Swedish farmers will be facing profitability challenges, which points to a need to reconsider the banks procedures considering risk management in credit granting for agricultural businesses.Today?s risk management will be given two complements in this study.

Tillämpning av prissäkring i spannmålsodlingen : en jämförelse mellan svenska lantbrukare
The Grain market is facing substantial changes. Tradionally, cereal has been a supply-led market i.e. supply conditions have had a major impact on price level or indirectly, through market interventions implemented through the Common Agriculture Policy (CAP). Just a few years ago, Sweden and the EU were not affected so strongly by world market prices for cereals. EU was a surplus-area and to a substantial degree a local market.
Hästen ? en medgörlig kompanjon eller en överexploaterad resurs?
The horse was domesticated about 6000 years ago. Since then humans have used the horse for different purposes, such as work force and in sports. Horses are social, group living animals that spend around 16-17 hours a day on grazing. Horses are often kept stabled in single boxes with a limited feeding time. The forage usually contains Grain-based concentrates and roughage.
Försäljning av närvärme :
To provide our company a new business opportunity I have in this essay examined the economical possibilities to sell energy.
I have chosen to do a case study on my own farm in this essay. The farm is focused to cropping and also have some properties for hire. The farm is situated in the village of Fjelie and that?s where the opportunity for selling heat are. Fjelie has about forty houses.
The idea is to build a plant where straw is being used as fuel.
Utvärdering av kalkstens egenskaper med laboratorie- och fältmetoder.
A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.
Olika uppvärmningssystem : en fallstudie i mellansverige
The purpose with this project is to compare different fuels when investing in a central combustion station at a case study farm. I have chosen to write about biofuel from an economical perspective. This because the heating costs are steadily increasing. Also because the farm in this case study has several different heating systems, which are neither profitable nor easy to work with. I have made calculations regarding usage of splinter, wood and Grain for the heating system.
Gyllene snittet och Fibonaccis talföljd
The purpose of this investigation was to find out more about students? spontaneous ideas about properties and transformations of matter. Examples of matter chosen are such which students know about from everyday life and focus is mainly on the questions if students know that all matter has weight and that matter is preserved in transformations.The method used is semi structured qualitative interviews with individual students. Different experiments were carried out together with the students who afterwards were interviewed. However, the students show varying answers and no generalizations can be done.
