Arkitekturstudie : Arkitekturhypotes för ett trådlöst processnät på Hylte Mill
Det här arbetet omfattar en arkitekturstudie av ett framtida processnät för Hylte Mill. Arkitekturstudien innefattar en mall för hur den framtida miljön kan se ut. Arkitekturhypotesen skall användas som en modell för företaget och visualisera ett trådlöst nätverkssystem vilket skall hjälpa operatörer att hämta information från SCADA-systemen via pekplattor. Metoden som använts för att ta fram arkitekturen grundar sig på utformningen av så kallade vypunkter. Vypunkter är vyer som skapas för att identifiera relationen mellan olika användare och systemet.
Lämpliga främmande trädslag för Kalmar och Mönsterås kommuner
This report concerns the for Sweden foreign tree species hybrid larch, hybrid aspen and poplar, and focuses on the area Kalmar and Mönsterås municipalities. The report shows that there are not only advantages with these species. The larch, the most common of the alien tree species has the greatest problems due to that its timber is difficult to sell in the area but also the Larch´s poor pulp quality and is more likely to be damaged by wildlife than the spruce is. Hybrid Aspen is much easier to sell and is used like regular aspen for match wood and textile pulp. Its disadvantage is the high cost for plants and to prevent damage from wildlife.
Optimering av indunstningsprocess
The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.
Reducering av produktionstryck i A-linan : Förflyttning av produkt
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.

Att samverka med hjälp av Gemensamma Individuella Vårdplaner : en undersökning av ett samverkansprojekt i Sollentuna kommun hösten/vintern 2007
The purpose of this paper is to provide an overview of how cooperation functions between the health services and social services within Sollentuna County Municipal area regarding clients and simultaneous or double diagnoses. Focusing more specifically; the paper also aims to provide additionally, an inquiry as to how the implementation of the Gemensam Individuell Vårdplan (GIVP) (The Integrated Individual Service Care Programme or (GIVP) functions within the Sollentuna Municipal County Area. The questions asked in the paper are: How do the Municipal and County Council personnel experience how the (GIVP) system functions in Sollentuna? How do the Municipal Council and County Council personnel respectively describe their own and their cooperative sister services rolls in terms of the implementation of the GIVP system in practice? The projection activates a hypothesis and tries to explain how the cooperation functions and provides an assessment as to how it functions or not as may be the case in practise. The authors attempt to achieve this using a combination of methodologies.
Ekonomiska konsekvenser av förändrad röttolerans vid Bravikens Pappersbruk :
The competition for Norway spruce pulp wood in Central Sweden increases, forcing the supply-structure of Holmen to face two important challenges. Firstly, it is of the outmost strategically importance to secure the long-term supply of Norway spruce pulp wood to the industries. Secondly, Holmen desires to increase the obtainable volume of Norway spruce pulp wood. This would enable the company to choose volumes in the lower price-segments and thereby decrease the dependency of costly marginal volumes.
As this work shows, one part in managing these challenges could be to lower the quality standards concerning root rot (Heterobasidium annosum).
Facts presented in the work shows that:
1. Technically, the TMP-industry of Braviken can handle a much more rotted pulp wood than that used today, although the cost of refinement increases.
Identifiering av designriktlinjer lämpade för integrerade videouppladdningstjänster
There is a lack of published material regarding designing graphical user interfaces of so called integrated video uploading services. The term integrated video uploading services refers to homepages that do not have video uploading as its primary purpose but which still offers that service to its visitors. The aim of this thesis was to improve the amount of published material about designing graphical user interfaces for integrated video uploading services. This was done by performing a literature study to find general design guidelines which can be applied to design of integrated video uploading services. Thereafter the functionality and design of dedicated video uploading services was analyzed.
Bibliotekariers yrkesroll på integrerade bibliotek: undersökning av bibliotekariers uppfattningar inom integrerade folk- och skolbibliotek
This master thesis deals with the problem of integrated libraries. The number of integrated public and school libraries has significantly increased over time. These libraries are integrated for different reasons, most often because of economic considerations. The goal of the thesis is to investigate librarians´ understanding and perceptions of the professional role in this type of integrated libraries. I have investigated how librarians see and interpret their own professional role, and what factors influence their perceptions in an integrated library.The three main questions are: How do the librarians explain their professional role in an integrated library? How does their professional role change because of the fact that they work in an integrated environment? What factors, according to the librarians, influence and/or change the professional role mostly? The data has been collected through interviews with eight librarians at integrated libraries.
BAMBUVISKOS ? En hållbar fiber för framtiden?
Naturskyddsföreningen gav författarna uppgiften att undersöka förekommande viskosprocesser och alternativa regenereringsprocesser, detta för att identifiera hur hållbara de är ur ett miljöperspektiv och vilka processer som går att applicera på bambu. Detta för att se möjligheten att märka bambuviskos med Bra Miljöval och för att klargöra frekvent uppkommande frågor angående bambuviskos. Syftet är att se på de olika processernas kemiska innehåll samt vilka utsläpp de orsakar till luft och vatten. Ett delmål med rapporten är att den ska kunna användas som material vid vidareutveckling av kriterierna för Bra Miljöval Textil. Resultat som erhållits vid jämförelser av studerad litteratur är att de betydande faktorerna för miljöpåverkan från massaframställningen samt viskos- och lyocellprocessen beror av: använda kemikalier i processen, energianvändningen och vilken typ av energi, möjligheten till rening av utsläpp till luft och vatten samt återvinning av energi och kemikalier.
Patent och företags storlek - finns det en tröskel till inträde?
Several studies have investigated the relationship between different measures of innovative activity, such as patent statistics and R&D expenditures and some have looked deeper into the differences between large and small firms regarding number of patents issued per employee or per R&D dollar. In this paper, the objective is to find out if there are any indications of a barrier to entry (due to economical factors, lack of knowledge etc) for small firms to get into the field of patent handling. The approach is to first set up a hypothesis based on some simple assumptions about how firms would make decisions about whether to apply for a patent or not and thereafter use econometric methods in an empirical investigation. The data used for this study are figures on number of employees, number of patents granted and R&D expenditures for the Swedish firms in the pulp and paper industry. The main conclusion is that, based on the analysis of the data from this rather limited group of firms, no such barrier can be seen..
Återvinning av dryckeskartonger : En studie som syftar till att öka återvinningsgraden av Tetra Paks förpackningar i Indonesien
People of the modern world consume more than they ever used to do. Because of the close correlation between consumption and the amount of waste, the waste volume is also expected to increase. The purpose of this study is to examine if some measures in the recycling process from Sweden could be implemented in Indonesia. In fact, Indonesia is one of the countries in which the waste management system is struggling. Tetra Pak, one of the world leading producer of food packaging, is studied in this report.
Yttrandefrihetens gränser : En prövning utifrån tre fall och tre teoretiker
Freedom of speech has been a well discussed subject. Great philosophers and theoretics like Plato, Voltaire, Locke and Mill have again and again showed the importance of freedom of speech. Since the world have become bystanders to a series of events that can only classify as crimes aganst freedom of speech, it has become more important to study the phenomenon and analyse it. By finding cases where the freedom of speech has been compromised and analyse them in frames of three different theories, the argument of truth, the argument of democracy and the argument of tolerance, this paper makes the boundaries of freedom of speech a little clearer, and also makes a discussion about how reasonable the boundaries are possible. Everything according to the three theories.
Analys och organisering av ö-drift för en samförbränningsstation vid Åmotsfors bruk
Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the
manufacturing of paper. Unpredictable energy prices and modernisation of the current
equipment has been the underlying factors to invest in a thermal power plant, mainly
driven by garbage. This facility will not only use the steam for paper production, it will
also generate electricity through a steam turbine. Today, when a fault on the supplying
line occurs which leads to disconnection of the external grid, all the support of electricity
to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper
production, which will cause severe economical losses.
Habiliteringspersonalens mångfacetterade yrkesroll - En studie hur personal arbetar med LSS intentioner inom integrerat boende
This essay is about the staff in integrated homes very complex profession and this is illustrated through twelve interviews in five integrated homes for disabled people. The profession changed when the institution closed and especially when the Law of Support and Service (LSS) was introduced in 1994.The purpose of this survey is to study how staff works with LSS intentions in integrated homes for disabled people and to increase the awareness about the structure of power and how this affects the daily life for those who live there.The main objective in this survey is to find out which the differences that lie between LSS intentions and the work that take place in integrated homes for disabled people. This survey tries to illustrate when and why these differences occur. This survey has a multidisciplinary perspective, where three models of disability and theories from Foucault, Sibley and Wendell have been included. The result shows that the staffs work is difficult, full of responsibility and has many facets.
