Vad påverkas odlarna av i den svenska morotsodlingen? :

In this degree project I write about how the farmers who grows carrots in Sweden get influenced by different rules, investments and demands. The Swedish agriculture are heading towards a harder time, and then you have to find new things to do. Now its hardly no profit to grow grain so you have find other crops. This paper is not a comparison between the contract cultivation to Findus and the cultivation where the farmer maked his products by a own company on the farm. If you have a small processing company on the farm, you have to increase the standard with different certificate. The farmer binds a lot of capital in machines, both field and in the process.

Ljudinstallationer i Sveriges utemiljö

When visiting Scaniaparken in Malmö you have the possibility of listening to music streaming out of grass-covered hills. In Helsingborg children can compose their own music and play for their friends on the playground. On a square in Nacka Strand you can hear birds singing in the quiet intervals of traf?c. What the places have in common are that they all contain sound installations.

Underlag för en pedagogisk turled i permakulturekobyn Suderbyn

Permaculture is a design system that aims at developing sustainable human settlements and self-maintained agriculture; it may also be used for community planning. The design system of permaculture aims at mimicking a natural ecosystem; this gives the advantage to make use of all the connections and mechanisms that exist in such a system.The purpose of this bachelor thesis was to compile and spread scientific information regarding five different themes within the areas of ecology, environmental science and permaculture. This was achieved through cooperation with the permaculture inspired Ecovillage Suberbyn in southern Gotland. Information about the central parts of a permaculture ecovillage was used as material for a series of signposts that will be located around the ecovillage Suderbyn. The five selected themes were: An overview of permaculture, The forest garden, The pond, Composting and The use of human excrement and urine..

Varför är det kvinnliga könet underrepresenterat vid Skogsmästarprogrammet? :

The purpose of this work is to find out what female students think about Skogsmästarprogrammet (Forest Management ? Bachelor?s Programme) at the Swedish University of Agriculture. The programme has existed since 1945 and in total over the years 1974 - 2007 about 10 % females have been studying at the programme. Today 15 % of the students are women, and the goal is to reach at least 30 %. The central question in the present work is to investigate how it is possible to increase the proportion of women.

Spenarnas kondition i automatiska mjölkningssystem : en studie av två spensprayer

Two post milkning teat dips (PMTD´s) were compared in an automatic milking system at Kungsängen Research Farm, owned by SLU (Swedish University of Agriculture) in Uppsala. In the experiment an evaluation system was used where teat condition regarding skin and teat ends was graded according to a scale where 1 was the best score and 5 the worst. The evaluation period was almost six months in total devided into four minor experimental periods. The technician scoring the teats did not know which PMTD that was currently used. Statistical analysis showed a significant difference between the two PMTD´s regarding teat skin condition, but not regarding teat ends.

Kväveläckage inom Tolångaåns dräneringsområde : modellering och åtgärdssimulering

Under de senaste 300 åren har jordbrukslandskapet i Sverige genomgått stora förändringar. I början av 1900-talet introducerades konstgödslet och efter andra världskriget ökade gödslingen dramatiskt i syfte att maximera produktionen. Detta har lett till att överskottet av kväve har spolats ut i vattendragen. I detta arbete har stor vikt lagts vid att skapa en egen kvävemodell i syfte att simulera kväveläckaget från jordbruksmarken i Tolångaåns dräneringsområde..

En ekonomisk utvärdering av framtida biobränslebaserade processkoncept inom energisektorn

The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

Maskinskydd på rullriktverk

ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.

Regressionsmodellering av dynamiska råemissioner från statiska mätningar

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

Batterilyft för telekom basstationer

The purpose with this thesis work was to design and build a technical aid for installingbatteries in telecom base stations. Today that job is done manually, since there is noequipment on the market for that purpose. Installing batteries in base stations manually isa very tough job.To get ideas for possible solutions a preliminary study on existing lift aids was done.From the preliminary study the conclusion that some kind of overhead crane would besuitable for the task was drawn. After that a lift for installing batteries in base stationswas designed, built and tested. The tests show that it is possible to minimize heavy liftingwhen installing batteries in telecom base stations, at a relatively low cost.ii.

Trädgård - en angelägen fråga : Carl Adam von Nolcken, Jordberga gods och trädgårdskulturens främjande i Skåne 1834-1857

Baron Carl Adam von Nolcken was born in 1811. In 1834 he took over Jordberga Estate in the South of Skåne from his father. The estate remained in his possession until his death in 1857. von Nolcken was interested in agriculture and horticulture from an early age and attended the newly started Institute of Agriculture, Degeberg in Västergötland in the early 1830:s. At Degeberg, von Nolcken learnt all about modern farming methods, which he put into practice on his own estate. von Nolcken was one of the persons who during the mid 19th century worked intensely to develop horticulture and the art of gardening in Skåne.

Jordbearbetningsstrategier på hösten inför vårsådd på tyngre lerjordar :

It is important for today?s farmers to minimize the costs for crop establishment, because of decreased prices and support from the EU. Farmers, who plow in autumn on heavy clay soil, often do some kind of tillage in autumn to get better soil structure before spring seeding. This is especially important when growing small seed crop, e.g. sugar beet and oil plants.
