Miljö- och hälsorisker med konstgräsplaner
In Sweden today many municipalities and sport clubs chooses to build artificial turfs becauseof the increased period of using the turfs during the year and less maintenance requirementsthan for natural grass fields. What could be problematic with artificial turfs is the rubbergranules used as infill material in the turf matt. The rubber granules are often made fromrecycled tires, which may contain for the human health and the environment, harmful substances.This was the reason why the Swedish Chemicals Agency commissioned a statusreport in 2006 which, among other things, concluded that the environmental and health risksassociated with granules made from recycled tiers in artificial turf fields were small, but thatthere could be a local environmental hazard. The purpose and objective of the risk assessmentwas to identify how artificial turf plans granules can affect recipients in the area closeto the pitches and provide input to reduce the spread of metals and substances harmful forboth human health and the surrounding environment. The work was divided into three parts:(1) the construction of artificial turf pitches and their material content, the spread of granulatesoutside the fields and disposal of artificial turf pitches.
Alternativa stråbränslen i växtföljden :
The purpose of this report is to find out which crops, that are good for strawfuel, and can be grown i the area around the city of Lund. The background of this report it that Lunds energy is planning to bild a biofuelheated thermal power station in Örtofta outside of Lund.
I have in the report limited me to the crops hemp, whole crop (triticale), reed canary
grass, elephant grass and jerusalem artichoke. I have through a documentary research
checked the crops, cultivabillity in the south of Sweden, and how they should fit, in the
Scanian crop sequence.
Hemp is an annual crop which probably could manage in the Scanian crop sequence.
Whole crop often triticale because of it´s high yield and low rate of shed seed. Could
also fit into the crop sequence of crop in Scanian. Triticale is annual, and could be
grown at the same kind of fields as used to wheat, whith is why it would be possible to
grow it in Scania.
Reed canary grass is a reedlike grass that is easy grown at most soils.
Pneumatiska artificiella muskler : med hjälp av en robotarm
According to the study [1] several firefighters are killed in action each year. This happens naturally in various ways. One of the major factors is that firefighters often do not know how the environment looks like, for example that a building in an industrial area contains hazardous gas cylinders. Without a solution, fire-fighters will continue to die in duty. It is therefore important to solve this problem so that we can minimize the risks and save lives.The goal of this project was a control system for pneumatic artificial muscles.
Strängluftning av vallfoder : Inverkan på ensilagets torkningförlopp, spill och smörsyratillväxt
When harvesting ley you hope to get a fast drying and a faster harvest. If there is a
system with round bales, you need to have a dry matter close to 45 %. To make this as
fast as possible, there is made a machine which pick up the grass with an pick-up. It
turn the grass over and put it behind the machine (figure 2 and 4). There are few tests
to prove the efficiency of this machine.
En jämförelse mellan får- och nötkreatursbetade hagmarker med avseende på populationsstorlek samt artsammansättning hos dagfjärilar och örter
Many of Europe?s day-living butterflies have shown decreasing populations during the last decades and many species are threatened. Many butterflies are dependent on managed semi-natural grasslands because of their richness in nectar sources and host plants for the butterfly larva. Swedish pastures are mostly managed through grazing. The number of cattle in Sweden have been decreasing while the number of sheep in the country increased by 30%.
Analys av artificiella marktyper vid vatten med hjälp av GIS, Värmlands län 2007
On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).
Vad orsakar höga ammoniumvärden i ensilage? :
High levels of ammonia in grass silage have been up for discussion by Swedish advisers. One
reason is that it is more difficult for the rumen-microbes to utilise high levels of ammonia. A
low level of ammonia is also good because if the cattle can use more of the protein in the
silage, they don?t need so much protein concentrate. That is very good for the economy at the
farm, and it is also good for the environmental problems caused by high levels of ammonia.
In this project, 24 samples of silage have been taken at 20 different farms in the south west of
Sweden.
Drankgivans och vallfoderkvaliténs effekt på konsumtion och produktion hos mjölkkor :
The coproduct, dried distillers grains + solubles (DDGS) from ethanol production based on wheat contains much rumen degradable protein and fiber with low digestibility. To compliment this quality in an effective way a grass silage low in protein and much digestible fiber is needed.
The aim of the study was to investigate the effects of adjusting the crude-protein concentration and fiber quality of the silage when feeding DDGS and of varying the
inclusion level of DDGS, when feeding the adjusted grass silage, on intake, milk yield and composition, faecal traits and feed efficiency.
Four different total mixed rations were compared. The normal grass-clover silage had a crude protein content of 17,8 % and an NDF content of 46,2 % of dry matter. The adapted grass silage had a crude protein content of 14,6 % and an NDF content of 52,9 % of dry matter. The diets were formulated to have similar nutritional content except for A + 4 which had a higher content of rumen degradable crude protein and a lower concentration of NDF.
Nedskrivningsprövning av goodwill ? ett verktyg för att jämna ut resultat?
År 2005 implementerades IFRS 3 och IAS 36 inom EU. Införandet innebär att företag årligen ska nedskrivningspröva goodwillvärdet istället för att linjärt skriva av posten under dess beräknade nyttjandeperiod. Nedskrivningsprövningen baseras på företagsledningens bedömningar om framtiden och flertalet studier har belyst att det nya regelverket lett till att goodwillposten utnyttjas opportunistiskt för att manipulera det rapporterade resultatet. I denna uppsats undersöks om det i en svensk kontext finns indikationer på att goodwillposten utnyttjas för artificial smoothing. Vi gör det genom att undersöka sambandet mellan goodwillintensitet och resultatvolatilitet och sambandet mellan onormalt stora vinster och goodwillnedskrivningar.Undersökningen visar att det föreligger ett signifikant negativt samband mellan goodwillintensitet och resultatvolatilitet och att det därmed finns indikationer på att goodwillposten utnyttjas för artificial smoothing.
Grazemore DSS för att optimera utnyttjandet av bete i mjölkproduktionen :
The aim of the study was to investigate if the Grazemore Decision Support System (DSS) is able to provide a grazing management strategy that gives a high utilisation of grazed grass in milk production in the north of Scandinavia. To do this, a grazing experiment was planed and performed during the summer 2005. Simulations in the DSS were run to get a suggestion of how the cows should graze, grazing calendar 1. Deviations and updates during the season resulted in the simulated grazing calendar 2.
During the experiment, the actual milk yield was recorded twice weekly. The difference between actual and predicted milk yield by Grazemore DSS was analysed statistically with regression analysis and the mean square prediction error (MSPE) was estimated.
Grovfodermajs : från odling till utfodring av växande nötkreatur
The use of forage maize has increased over the last years. The aim of this litterateur review was to summarize a part of the research that has been conducted on forage maize for growing cattle, including cultivation and conservation of the maize. The forage maize is planted in April or the beginning of May when the temperature in the soil is between 6 and 10°C. Maize needs high temperatures and much water. Maize is harvested in the autumn when the dry matter (DM) is more then 30% or the plants have been exposed to the first frost in the autumn.
Artificiell Insemination (AI) hos hund : en sammanställning över användandet av seminering inom hundaveln i Sverige under åren 1995-2004
The use of artificial insemination (A.I.) as an alternative to normal mating in dog breeding in Sweden are controlled by regulations from the Swedish Board of Agriculture and by ethical rules assigned by the Swedish Kennel Club. Only veterinarians, who have a specific certificate and are specially trained and educated, are allowed to perform inseminations in dogs. Each artificial insemination must be documented and reported to the Swedish Kennel Club (SKK) which, on the behalf of the Swedish Board of Agriculture, yearly presents statistics concerning the use of A.I. in Sweden. The objective of this study was to illustrate the use of artificial insemination in dog breeding in Sweden for the last decade, using the yearly reports from the Kennel Club during the period of 1995 to 2004.
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.
Methane production from dairy cows : relations between enteric production and production from faeces and urine
Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.
Biobränsle från det jämtländska jordbruket : en studie om lantbrukarnas alternativkostnader vid odling av rörflen
The use of fossil fuels such as coal and gas are a contributor to the global warming. The climate change is a worldwide problem with far reaching consequences that is believed to be very expensive. The United Nations has been introducing a framework convention on climate change. One component of the convention is the Kyoto protocol. The protocol is obligating the developed countries to decrease their emissions of greenhouse gases by 5.2 percent during the time period 2008-2012.
