In this thesis an energy analysis of ethanol production at the ethanol plant of Lantmännen Agroetanol in Norrköping has been performed. The ethanol plant has been studied in combination with Händelöverket, the combined heat and power plant which provides the ethanol process with steam. The purpose of this study was to determine the energy consumption for the whole production chain from grain to ethanol. The analysis has included the energy consumption for cultivation of grain, production of chemicals, the production chain for wood chips, the steam production and the ethanol plant. The grain and wood chips are both considered raw materials there for the energy content in these are not included as energy input in the system.

Lean Production har sedan länge enbart varit förknippad med tillverkningsindustrin och främst Toyota genom Toyota Production System(TPS). På senare år har Lean Production i allt högre grad introducerats och integrerats i tjänsteföretag under beteckningen Lean Service. Bankbranschen är en bransch där aktörer globalt anammat de bakomliggande filosofierna av Lean Production och Lean Service. I det här arbetet har en undersökning gjorts kring huruvida Lean Production existerar inom svenska banker och om så är fallet hur filosofierna inom Lean Production präglar bankerna. De tre bankerna som valts för undersökningen är de svenska storbanker Nordea, SEB och Handelsbanken.

KRAV-certified organic dairy herds generally have a lower milk yield than conventional dairy herds. A high-level of milk yield requires a feeding regime with high amounts of concentrates, a factor known to contribute to the development of claw lesions (Bergsten, C. 2003). The aim of this study was to compare claw health between organic and conventional dairy herds in free and tie stall systems. The number of herds from different domestic animal health associations was chosen in proportion to the association´s total portion of Swedish dairy producing herds of each type, respectively.

One of the most distinguishing features of contemporary globalisation is production fragmentation, a splitting up of the manufacturing of a good into several different stages. Production fragmentation creates new opportunities through vertical specialization; a country incapable of mastering the entire production process may specialize in the manufacturing of one separate part. The aim of this thesis is to examine to what extent international integration affects a country?s ability to engage in vertical specialization in an industry characterized by production fragmentation. The analysis focuses on the european integration process over the last decade, where countries in eastern Europe with relatively low labour costs have been integrated with more capital abundant western economies.

Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden. This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation. The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.

The aim of this study was to detect antibodies in swine serum against proteins in soy beans, wheat, oat and barley. Two methods were used: agar gel immunodiffusion test (AGID), and SDS-PAGE followed by immunoblotting. The sera examined originated (I) from piglets younger than one week (negative control), (II) pigs from a feed trial with soy bean in a herd with PMWS, and (III) pigs inoculated with Brachyspira hyodysenteriae and Escherichia coli after being fed with soy. The AGID-test was negative concerning all examined sera which were analysed against proteins in soy bean, wheat, oat and barley. In the experiment based on immunoblot antibodies were demonstrated within all three groups of examined pigs.

Many companies do not register all the stops that occur in a production plant, it often takes longer to report than to fix the problem. If no problems are registered, you cannot trace where the problems arise.This master thesis was performed at AcobiaFLUX and they have noticed an increased demand from their customers to trace problems raised in their processes. The aim of the thesis was to find out how a tool to monitor a process best could be developed. Then the most essential from the theoretical base was developed into a useful tool for operators. For the operators to know if the process utilizes the full capacity of a process, the tool presents a measure of the Overall Equipment Efficiency, OEE.

Green roofs have seen a revival in the society of today. They provide many functions of which both society as a whole and the individual can take part. In particular extensive green roofs, that requires little or even zero maintenance, provides very valuable functions. Green roofs affect our environment and our economy in a positive manner as well as the physical expression of buildings. In this bachelor thesis the impact of green roofs on society has been examined throughout literature studies. The result as a compilation of contemporary research in this field is presented together with a discussion about the use of green roofs in general. The two major arguments for an extended use of green roofs are, the high stormwater retention capacity and the cost-benefits seen over time compared to a conventional roof.

Drinking water from drilled wells has a high content of iron and other minerals in many places in Sweden. Questions about the association between the quality of drinking water and the health of dairy cows are regulary asked both by advisers and dairy farmers. There are so far not many studies published about the relevance for high iron content in water and dairy cow health and production. Therefore, the aim of this study was to investigate if there is a connection between the iron content in water and the health of dairy cows. Initially a literature study was made about iron and it´s function in ruminants.

Dairy cows transform grass to milk with help from ruminal microorganisms that can digest indigestible fiber in their feed. The digestive system of the cow is adapted to a diet consisting of forage and disorders like acidosis, laminitis and abomasal displacement can occur if the feed contains too much starch. To achieve the highest production possible the cow has to be given a high amount of concentrate or grain as the difference in milk yield is significant, approximately 1000 kg energy corrected milk per cow and year between conventional and organic cows that are fed a lower versus a higher share of forage. If the cow shall be able to eat the same amount of energy from forage as from grain or concentrate the eating- and rumination time gets longer and she might not be able to eat enough, which will result in a lower milk yield and will make it harder for the cow to recover from the negative energy balance that originate from the beginning of the lactation. Fat and in a sense protein content differs also depending on if the cow is given a high or low share of forage..

This paper is about the new methods and metrics used in industry and business today striving for better revenues and larger market shares. It investigates the relations between the old fordistic and tayloristic way of manufacturing and compares it to the models used in industry today for being competitive, seeking to please customers and becoming more flexible. More specific the paper is about if Six Sigma and lean production are the key for succeeding these days. SKF:s factory in Gothenburg and other companies will make an example for how these methods are used in practice.The aim is to try to answer if these systems with inherited tools and methods are the right way to get the flexibility that is needed for being able to deliver the right goods to customers and market. For a company to be flexible decisions must be made fast and needed changes must be able to be done easy and without too large costs and investments.

Stands where pre commercial thinning has been ignored or inadequate often tend to have high stem density and low average diameter when they reach heights of thinning. In such stands, it can often be expensive to do a conventional pulpwood harvest as a first thinning. This study investigates the development of the stands and the economic outcome of forest fuel extraction, or a combined harvest as alternatives to the ordinary pulpwood harvest. Simulations in Heureka StandWise were performed for two thin and dense stands, which were constructed by data from the Swedish National Forest Inventory. The simulations show that the extraction of forest fuel in first thinning at an early stage can provide higher net revenue compared to conventional pulpwood harvest at the same time or later.

The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.
