Ekonomisk värdering av användandet av underbett på timmerbilar
Holmen Skog has in some places in their operation area access to timber trucks with centre mounted scrapers. They make transportation more flexible and reduce reliance on contractors for road maintenance. The trucks with centre mounted scrapers have a higher tare weight, making them less productive and therefore they receive compensation with a 0.75 % increase on transportation price.
The purpose of this study was to investigate what actions a timber truck with centre mounted scraper can perform with acceptable quality in winter, and to examine if it is an economically profitable solution for the truck operator and charterer.
The study was done in three stages; interviews, performance analysis of the transportations carried out and an economic analysis with the help of Sven Erik Gilles spreadsheet tool. The study included the districts Delsbo and Hudiksvall.

Biogas till kraftvärme på Wapnö : en projektanalys utifrån ett företagsekonomiskt perspektiv
Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure.
The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.
Internationell jordbruksmark till salu - Nationell suveränitet, fattigdomsbekämpning & visionen om en hållbar utveckling
During 2008 we experienced an expansion of large scale investments in foreign farmland. This increasing trend has become a political hot-spot, but there is not much research available within the field. Due to a lack of research it remains a vital task to outline the potential effects of this trend. Drawing on existing ideas from some of the main actors within the field, The Food and Agriculture Organization of the United Nations (FAO), The World Bank, International Food Policy Research Institute (IFPRI) and the latest G8 summit on agriculture, four main purposes are set out for this paper. First, to outline some of the underlying mechanisms behind the trend is considered crucial for the understanding of the nature of these investments.
Value Stream Mapping över brevets väg i Uppsamlingsprocessen : En fallstudie på Postens brevterminal i Alvesta
Background: The demand for sending letters, in the traditional aspect, has decreased because of electronic sources which have replaced a big part of letter communication. The Postal Service constantly strives for lowering costs and due to the changeable demand, a greater awareness is required regarding recourses and their usage. The previously mentioned measures in combination with commonly occurring quality issues during the collective process at the letter terminal in Alvesta would be improved by applying a lean-perspective to the process. A first step towards saving of time is to apply the ?value stream mapping?-method on the collective process for small and large letters.Purpose: To map the process of collection for small and large letters to be able to identify waste of recourses and furthermore give suggestions on how the Postal Service would be able to reduce the waste of recourses identified.

Framtagning av en utvecklingsprocess för automation - baserat på konceptet Lean Automation
Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.
Kolbalansen vid olika skötselstrategier för skogen på Tagels fastighet.
Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.
Kostnader vid gallring med flerträdshanterande aggregat, från skog till industri
Profit in first commercial thinnings of today is hard to achieve. This is because of prevailing pulpwood prices and because of high costs of logging and transport. To reduce these costs higher productivity is advocated. One way to increase the productivity is the use of multi-tree handling harvester heads. The aim of this study was to calculate logging and transport costs in first thinnings, where multi-tree handling has been used.

Patienters upplevelse av att vårdas i isolering : en litteraturöversikt
Background: Isolation care may be necessary when a patient is carrying infection or is being inflicted with disease that causes deficit immune system. Being isolated means that the patient is in a confined space and may stay only there. Even in ancient times, people discovered the importance of isolating people carrying an infection from the rest of society. According to the Infectious Diseases Act, patients should be isolated in order to reduce the spread of infection both from the patient to the surroundings as well as the opposite. Isolation care can be psychologically stressful for some patients.
Studie av Karlskogas fjärrvärmenät för att sänka returtemperaturen
A district heating plant has the advantage that it can take advantage of the waste heat from industries and use of cheap fuels to produce heat. But for the long term is competitive requires that energy is also saved in district heating plants. One way to save energy in a district heating system is to increasing cooling to the return temperature. This leads to less power needed to drive the distribution pumps, and that more energy could be extracted from the same amount of fuel by an improved flue gas condensation.In Karlskoga the return temperature into the district heating plant is high. They would therefore reduce the return temperature in order to extract more energy from the flue gases.
Metod för att mäta förändring av city logistik : - En casestudie på Sandvikens kommun
To distribute goods to customers in urban areas is necessary to support the economic and social development in the cities, but has consequences that affect both residents of cities as well as the environment. The environmental effects of these types of transport involves not only the emissions of various pollutants, but also an increased noise level inside the cities. Many companies and organizations are working hard to change the distribution pattern to streamline transport in the urban area, while environmental impact is reduced. This is in line with what is called the City Logistics. The purpose of this thesis is to create a method for describing and measuring a given transport solution in order to compare it with an altered transport solution to achieve a more sustainable development.
