Examensarbetet har utförts på Sandvik Coromant i Gimo, GH. Produktionsenheten tillverkar hårdmetallskär för borrning, svarvning och fräsning. Arbetet syftar till att undersöka metoder för att minska material i arbete samt förkorta ledtiderna på enheten. För att uppnå en resurssnålare produktion undersöks möjligheterna för Lean Production och andra arbetssätt som anses ge förbättringar av flödet. Som grund till arbetet ligger intervjuer av personal på enheten i Gimo, litteraturstudier samt ett besök på ett företag inom Sandvik koncernen som lyckats med att minska material i arbete samt förkortat sina ledtider.
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.
Gestaltning av vägar i Skåne - kopplat till sju regionalt viktiga stråk :
This work derives from the question ?What is a beautiful road??. The question is being discussed in interviews with two employees at the Swedish National Road Administration and two former members of the ?Council of environment and beauty? at the Swedish National Road Administration. The interviews are summarized in my own discussion about the concept of ?Beautiful roads?.
Kväve i Östra Mälaren : hur kunskap förvaltas och används i tillståndsprocesser
The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.
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

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.

Inhysning av struts :
The Swedish ostrich production started about thirteen years ago and still there are no Swedish recommendations regarding ostriches? space requirements. The European Council give recommendations and the Swedish Board of Agriculture (SJV) has a proposal, but so far the producers follow Danish regulations regarding space requirements. The Swedish Animal Welfare Agency are about to set standards for the ostriches? space requirements, and therefore the Swedish ostrich producers, together with The Federation of Swedish Farmers (LRF) ask for a scientific background to these decisions.
This thesis is a preliminary study at the prospect of a future experiment on which factors important for ostriches? space requirements and welfare will be examined more thouroughly.
