Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for machine operators.The education about deposits for machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.

This paper is a case study on Bradley E. Manning, famous for leaking classified intelligence to media, or in the charge sheet?s words: ?knowingly give intelligence to the enemy, through indirect means.? My opinion is that this sort of dilemma is a question of values, how you view the world and, most important of all, human rights and the philosophy of rights. Therefore I decided to sort out the arguments regarding the issue of freedom of speech versus the state?s need for protection.

Hallstaviks papermill is an industry plant within Holmen Paper. Hallstavik is a mechanical mill and produce newspaper and journal paper. During year 2000, Hallstavik used approximate 1.200 m3f spruce, either as logs or chips from sawmills. Due to that the production is running continuously the mill also needs raw material at the same rate. At some periods the supply of raw material cannot keep up pace.

Today's society is facing major challenges. In order to reduce the climate impact fossil fuels should be replaced with fuels that do not contribute to the greenhouse effect. The growing population generates organic waste originating from industry and households so called organic fraction of municipal solid waste (OFMSW). Through anaerobic digestion, waste can be utilized to produce energy-rich methane gas. In this way, waste can be a resource instead of a burden on society.

This thesis analyses the prerequisites, profitability and competitiveness of eucalyptus plantation on the Iberian Peninsula and in Brazil. The thesis has a macro perspective and analyses a typical hectare of eucalyptus in each studied region. A survey methodology was used as a strategy to cover a broad perspective using expert respondents. The regions studied on the Iberian Peninsula were the ones found suitable for eucalyptus plantations from an economic point of view. The studied regions were Huelva in the South West of Spain, Galicia in the North West of Spain and Portugal.

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Målet med detta examensarbete har varit att utföra en energikartläggning på Nymölla Bruk med utgångspunkt i företagets be?ntliga energiaspektregister. Syftet har varit att tydliggöra hur energianvändningen på Nymölla Bruk ser ut. Bakgrunden till detta arbete är företagets deltagande i programmet för energieffektivisering i energiintensiv industri (PFE).I examensarbetet har en energikartläggning på Nymölla Bruk för år 2010 utförts. Fallstudien delades in i två steg där första steget i studien var att kartlägga energi?ödena in och ut från bruket.Andra delen av studien innefattade att kartlägga de interna processerna och deras energi?öden.

Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged. The milling process creates a wide range of particle sizes.

In the process of making carton boards into Skoghall Mill, are great quantities of water being contaminated. This water has to be treated before it is possible to release into the recipient, Kattfjorden. One of the contaminations that is important to extract from the wastewater, is organic carbon (measured as TOC-total organic carbon) because microbiological breakdown can lead to the bottom becomig free of oxygen.The wastewater treatment at Skoghall Mill is done through an external wastewater treatment that is located at the factory. The biological treatment (aerated lagoon) is a 140 000 m3 water pool with surface aerator, which is give oxygen to the water. In the lagoon live microorganisms who performs the biggest part of the TOC-reduction.One problem with the lagoon is that the treatment of TOC is considerably worse during wintertime than during summertime.

Södra Cell Mörrum is one of the five paper pulp plants that are included in Södra Cell, and the paper pulp that is produced here is not only sold to Swedish paper mills. Most of the paper pulp is exported to different countries in Europe. In the manufacturing process the plant needs different kind of process water and there are guideline values for how much copper, iron and sodium this water is allowed to contain. Analyzes of this water is in the current situation done with an atomic absorption spectrometric instrument (AAS-instrument) with a flame. Measurements done with flame-AAS of samples that have concentrations near the guideline values for copper, iron and sodium, are not reliable. The reason for not being reliable is that the quantitation limits of these metals are higher than the limit values.

Benchmarking is an established method of working which is often used in order to develop the quality of the organization. However, almost 70% of the organizations with benchmarking fail due to the lack of planning and structuring of the benchmarking exercise. Maintenance sections in the paper and pulp industry are one of those who have decided to conduct benchmarking. Therefore, the purpose of this study is to gain knowledge of how the maintenance sections in the paper and pulp industry deliberately structure and plan to use benchmarking as a driving force for quality development in the maintenance sections.The study is a hermeneutic case study. Telephone interviews and document analysis have been used as data acquisition methods.The results show that there is a lack of both planning and structuring in the benchmarking process, and lack of management commitment for quality improvements within industrial maintenance.

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.

A new curriculum, Lgr11, was introduced in Sweden during the Autumn Semester 2011. My aim in this paper is to investigate whether an integrated and interdisciplinary approach is possible within this new Swedish curriculum.Firstly, I will describe the approach to integration and interdisciplinary work used in the new Swedish curriculum. Secondly, I will analyze whether the curriculum allows for an integrated and interdisciplinary work.The method used in this paper is a qualitative textual analysis and analyzing the new curriculum´s approach to integration and interdisciplinary education has been the focus. The analysis has been based on the explicit and implicit basics of integration and interdisciplinary work in the curriculum.I assume theories of subject integration and curricula to come up with my results in the paper.To conclude, the results of my analysis of the curriculum show that an integrated and interdisciplinary approach is not only possible, but it is also each school Principal's responsibility as well as part of each teacher`s objective. The Principal's responsibility is to ensure that the integration and interdisciplinary approach is undertaken in school. The curriculum is clear that teachers should let their students work interdisciplinary as well as vary their methods of teaching.
