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..

Population and management models for the Swedish wild boar (Sus scrofa)

The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.

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.

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.

Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud? : Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator

Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.

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.
