Fairtrade coffee, fair enough? : a study comparing Fairtrade certified coffee producers and uncertified coffee producers in Aceh Tengah, Indonesia
This study compare if there is any differences between Fairtrade certified and uncertified coffee producers in Aceh Tengah, Indonesia. The aim was to compare the way the two groups of farmers produces their coffee and see if there were any differences between them, income, post harvest, production etc. During a visit in the district of Aceh Tengah, producers from both groups were given a questionnaire with questions about their farm and their production. The results of the questionnaires showed that the certified producers felt they had benefits being a part of a certified cooperative. Even with the experienced benefits the certified cooperatives gave the connected producers, like agronomy consultation and workshops the uncertified producers had a higher income from the coffee per hectare.
This study also indicated that introduction and presence of Fairtrade and the connection to the world market Fairtrade brings with it, has gained the entire area, for example with more stabile coffee prices..

Användning av CAD-data vid NC-programmering
The degree project is performed at Metso Kamfab. The production is aimed on machines everything from handling of fiber to paper pulp. Metso Fiber and Kamfab are using Pro/Engineer for design and blueprint production. The processing department types the NC-programs in notepad on the basis of the blueprints, the CAD-dates that already is there are not used. The aim with the work is to study if Kamfab can use CAM-system for processing and production of programs for their NC-machines.
3D-modell av torkcyklon - Examensarbete på Metso Panelboard AB i Sundsvall
This Bachelor of Science thesis was carried out at Metso Panelboard AB, located in
Sundsvall, Sweden. The work lasted for 10 weeks and began at the end of February 2007.
Metso Panelboard is one of the leading suppliers of complete lines, single machines,
engineering knowledge and after-market services to the fibreboard industries.
The task involved building a 3D-model of a dryer cyclone in the CAD-program
Pro/ENGINEER. A dryer cyclone is the part where the tree fibres are dried in the process of
manufacturing fibreboards. Currently, it takes about two weeks to draw a dryer cyclone. By
creating a 3D-model of it, which should have the functionality to be generated to different
sizes, the goal is to decrease the drawing time to about 20 hours and to increase the quality of
the work.
This report includes the fundamental theories behind the manufacturing of fibreboards with
focus on the dryer cyclone.
LAN-Uppgradering
The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.
Granskning av kvalitetssäkringsarbetet vid en ICC-profilbaserad trycksaksproduktion
To make your company change from a conventional workflow to an ICC-based workflow you need tomake investments in time and money. On the other hand you get your reward in terms of a stable andquality safe production. To choose this way of adjusting your company to new routines requires accuracyas well as a great deal of commitment. It is not only about having the right equipment. There area lot of factors that affect the quality of production.Our ambition with this report is to bring out the importance of general thinking when it comes toICC-profiling and to discuss on which basis printing profiles should be created.
Design och konstruktion av laborationsutrustning till en kraftelektronikkurs
The purpose of this degree project was to build laboratory equipment for a new course in power electronics that starts this autumn 2010 at Uppsala University. The equipment is intended for student labs and it covers the most important areas of the course including rectifying, buck-/boost-converters and PWM-modulation. It is built as one sealed unit where all the electronics are built-in but visible and it has a connection board where students safely can connect the different circuits. The project has advanced from theoretical studies of circuit design, choosing of components and simulations to drawing the printed circuit board (PCB), soldering, case building, final testing and troubleshooting - basically most steps from an early idea to a final product. Measurements on the final product gave about the same results as the earlier simulations of the circuits and the result is overall satisfying..
Metoder att förhindra nedisning av vindkraftverksblad
ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.
Verktyg för värdering av miljöpåverkan vid investeringar i det svenska elstamnätet
During the period 2009-2013, investments in the Swedish national grid increase by a factor of ten compared to previous years. In order to fulfil their mission to manage the national grid in a safe, efficient and environmentally sound way, Svenska Kraftnät (Swedish National Grid) needs to take all these perspectives into account while planning new investments. To compare and relate perspectives of technology, economy and environment the same yard stick must be used. That yard stick is commonly money. A problem arises however as environmental issues are difficult to price.The purpose of this master?s degree project was to develop a tool for evaluation of environmental impact related to investments in the Swedish national grid.
Koncerninterna vinstöverföringar - finns det någon strategi?
The purpose of our essay is to find out if there are any strategies for profit transactions in a group. To realise our purpose we conducted two case studies with interviews. But we can not draw any general conclusions.To conduct the research we had to build a theory. In this theory we found motives to do profit transactions and how to do it. We also thought that there had to be some conflicts between the motives and the manager´s interests.In our analysis we found that financing the dividend was a strong reason to make profit transactions between companies in the group.
Kan befattningen påverka inre arbetsmotivation och psykiskt välbefinnande? : En studie med tjänstemän med olika grad av individuella krav och kontroll på arbetet
The aim of this study was to examine differences in the experience of intrinsic work-motivation and to examine changes depending on profession, where the purchasers experienced a higher level of individual demands and control than the production leaders. Another purpose was to see how the intrinsic motivation needs predicted mental well-being in the professions. The study was carried out using an internet survey that was distributed by e-mail, there were 98 participants. Two questionnaires were used; Basic Need at Work scale (W-BNS) measured intrinsic motivation and GHQ12 measured mental well-being. The result showed that the staff overall had high intrinsic motivation with highest scores on relatedness followed by competence and lastly autonomy.
Small scale pig production in Takeo province ina rural area of Cambodia
Cambodia, in Southeast Asia, has tropical monsoonal climate with distinct dry and rain seasons. Many people are poor and live in rural areas. Farmers mainly culture rice, and raise pigs, cattle and poultry as well. During two months, a minor field study was performed in Cambodia. The main purpose was to evaluate the impact of contributions done by projects that started in 2005 and were managed by the local organization CelAgrid.
Klöver i ensilage till suggor - effekter på reproduktion och produktivitet
The weather has been extremely rainy the last summers in Sweden. Because of the rain, a lot of harvested straw has been lost since it was too wet to store. When the pig producers couldn?t get enough straw to use as bedding, an alternative was requested. Silage is a realistic alternative to straw but since silage often contains clover, it may not be suitable to use in pig production since clover is rich in phytoestrogens.
Tusen motstridiga röster : Tvära kast, djupa tröstlösa lidanden, och extrema sinnestillstånd i noveller av Ulla Bjerne
This study examines four short stories- ?Gudarnes like?, ?Vänner?, ?Lolo? and ?Kvinnor? - in a novel called Upptäckter written by Ulla Bjerne in 1918. My aim has been to study whether Bjerne in these stories writes from a New Woman- position. The New Woman novel as a genre flourished around the end of the 19th and the beginning of the 20th century. I have also studied whether Bjerne in these short stories uses a melodramatic style.
