This report is a B.Sc. Forestry thesis work at the school for Forest Management, SLU. The work was an assignment from the forest owners? association Mellanskog. The aim of the work where to investigate the economical result of removing undergrowth trees before first thinning, and a follow-up of the contractors and their compliance with Mellanskog standards. This thesis work was divided in three parts: The first was to find a relation between the net volume from the first thinning and the cost of cleaning undergrowth trees. Secondly there was a follow-up in the field, to investigate whether the contractors have done the undergrowth cleaning according to Mellanskog?s directives.

Följande rapport är resultatet av det examensarbete som utförts våren 2011 inom innovativ produktion/logistik vid Mälardalens Högskola. Examensarbete behandlar ämnet Green Production med fokus på skillnader mellan ett produktionssystem som bygger på Lean Production och ett som bygger på Green Production. Områden som berörs i rapporten är de verktyg som används i de olika produktionssystemen, hur arbetet med miljöförbättrande åtgärder kan se ut i praktiken samt vilka svårigheter som finns vid arbete med miljöförbättrande åtgärder i ett företag. Examensarbetet består av en litteraturstudie där aktuell litteratur studerats inom området samt en intervjustudie som genomförts med insatta inom miljöfrågor kopplat till produktion samt operatörer.Bakgrunden till examensarbetet grundar sig i att världen står inför en framtid där många utav de råmaterial som används idag vid produktion inte kommer att kunna nyttjas i framtiden. Detta i kombination med de miljöproblem som människan åsamkat, har bidragit till att många företag insett att miljöaspekter måste vara i åtanke genom hela produktionsprocessen.Den uppfattning som erhållits genom intervjustudierna är att det är viktigt för ett företag att visa att de arbetar med miljöförbättrande åtgärder.

This thesis on the sustainable urban development has the intent to discuss the conservator?s position in alteration of the built environment. An essential component of the thesis consists of a case study in the form of an entry in an open architectural competition for the development of Furuset, an urban residential area in Norway. The thesis? discussion is based on two approaches to change and socio-economic transformations, considered being dominant within the heritage theory and practice: the production of ideas and great narratives and conservation as an instrumental tool.

There are various arguments for using total mixed rations (TMR) or not. Cows can easily become fat and thus poorly utilize the feed while it can be stated that TMR also has a positive effect on cows? health and wellbeing as the rumen environment is more constant than when separate feeding is applied. Studies do show that that especially low yielding cows kept in groups get fatter when fed TMR. The overfeeding implicates higher feeding costs. This study included 10 herds where 5 had TMR and 5 hade separate feeding of forage and concentrates.

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

This master thesis is about the collaboration between the custom dairy heifer grower and thedairy producer.The custom dairy heifer grower is a rather unusual strategy of reproductive management inSweden compared to other countries like U.S. and Denmark where the specialization withindairy production gone much further. In these countries the research also has reached muchfurther within this type of industry. However in Sweden there has been research made in thearea of collaboration, but then only within collaborations in the industries of crop production,dairy production and pork meat.The down going trend of profitability within dairy production together with poor profitabilityin the beef industry could partly remedy if more collaborations around heifer contractingwould arise. But since the industry still is of a rare kind in Sweden the knowledge about howthese types of collaborative arrangements works and their contracts are put together is poor.By that the aim of this master thesis is formulated as follows: "how is usually thecollaborative arrangement between the dairy producer and custom dairy heifer growerdesigned".

To invent an optimized product is a complicated process. This process is only half of the work. It is equally important to develop a production system that can produce the product in an  efficient and ergonomic way.After several evaluations of conceptual and detailed drawings a final idea has come to light.The idea intends, to the maximum extent, utilize the facility in a more efficient way through moving assembly lines and stations closer to the flock section and the stock for complete products. To make the production better, stations are placed in more logical places given the assignment they are supposed to accomplish. This improves the material flow radically.

The effects from a planned wind farm on the grid utility Gävle Energis electrical grid have been studied. The wind farm is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power between 46 MW and 57.5 MW. The grid connection will be made at 70 kV. The aim of the analysis was to determine what effects the wind farm would have on the power grid in the form of electrical disturbances (flicker etc.), need for new investment and raised operational cost. To allow the connection of the wind farm technical solutions (new lines, power stations and grid reinforcements) have been constructed.

Syftet med denna uppsats är att skapa en förståelse för vilka bakomliggande krafterna som gör att människor använder Blocket och se vilka strategier som kan användas för att bryta dessa krafter..

Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Quality was earlier only an issue for the company?s quality departments but today is the entire organization involved in quality- and improvements work. With the customers in focus, both external and internal, quality and improvement work should be integrated in the daily activities. The management shall state goals and visions together with a policy. Through participation the correct requirements for a successful work are created.With SPC, statistics process control, there is an opportunity to perceive variations in the process and with the correct tools make it stable.

The agriculture is today in a development that leads to bigger and bigger units in the primary production. To be able to follow this development many companies chooses to cooperate in different ways. The most radical change is when farmers fuses with other farmers and merge into to a big collectively owned operation firm. The reason behind this idea is that the firms achieve the big companies advantages by being complement to each other. The purpose of this essay is to make an economic analysis of two crop production companies who works together in an operation firm.

Idag är det inte många textilföretag som har möjlighet att ha strumpproduktion i ett land som Sverige på grund av lönsamhetsskäl. Det är billigare att producera i låglöneländer i Europa eller Asien, men det tär istället på våra naturresurser och vår miljö att transportera produkter fram och tillbaka. På grund av de höjda lönerna i Kina och valutakursen för euron som höjts drastiskt i Europa har Sverige dock kommit till ett läge då det blir ekonomiskt lönsamt att flytta tillbaka en del av produktionen till Sverige. Dessutom ökar trenden med ekologiska och närproducerade varor, vilket ökar efterfrågan på svensktillverkade produkter. Studien syftar till att ge privatpersoner och företag ett underlag till att undersöka sina möjligheter för produktion av strumpor på den svenska marknaden.Utvecklingen av strumpproduktionen i Sverige pågår hela tiden och företagen uppdaterar sina maskinparker och utbildar sina anställda, vilket leder till en utveckling av marknaden.

The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.
