Kappa Control with Online Analyzer Using Samples from the Digester's Mid-phase

In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.

Förebyggande förbättringsarbete med Design for Six Sigma

Design for Six Sigma (DFSS) is a further development of the Six Sigma draft to carry through preventing quality measures in developing and designing of new products and processes. With increasing demands on enterprises development processes to be more safety and faster the need of DFSS arise as a product, process and service development concept in the organisations. Design for Six Sigma aims to improve and structure the development process of an organisation and consider the application of the innovation problem solving. The concept aims to leave the structure of the traditional Six Sigma concept and instead, from an innovative perspective, search for new solutions to existing problems. The concept constitute of a toolbox with a lot of quality tools that are divided into phases in a development model.

Döden är livsviktig : fem kuratorers bemötande av obotligt sjuka och deras bild av de sjukas upplevelser

The aim of this undergraduate thesis was to explore how the welfare officers at palliative units in Stockholm respond to the patients? thoughts and experiences during the last phase of life, as well as exploring their picture of the patients experiences. The research questions of the study were:? How do the welfare officers relate to the patients? experience of their death? ? In what way do the welfare officers respond to the dying patient and his or her experiences?? What knowledge/experience do the welfare officers have and what knowledge/experience do they consider is needed in their profession?To answer the research questions a qualitative method was used where five welfare officers in three different palliative units were interviewed. The empirical material was analysed through meaning concentration and are presented using exact quotations.

Evaluation of a behaviour protocol for use in recording the behaviour of horses following administration of methadone

There is a need for correct and adequate pain assessment in horses. Methadone is used in pain management in horses but the full pharmacokinetic picture of methadone is not yet known. The aim of this pilot study was to develop a behaviour protocol and suggest a reliable recording method for use in a larger research project with an aim to potentially correlate behaviours to concentration of methadone in blood. In this study two coldblooded trotters were given methadone intravenously with doses of 0.1 mg/kg for horse 1 and 0.2 mg/kg for horse 2. The horses were videotaped pre and post methadone administration.

Användarundervisning och uppsatsarbete: Några ekonomistudenters uppfattningar av undervisningens betydelse för informationssökning och -användning

The purpose of this Master?s thesis is to investigate a few economy students? perceptions of user education connected to essay work, focusing on aspects of information literacy of importance to the studies and the role of the user education in this context. The study was conducted with a qualitative approach. Five economy students were interviewed regarding their experiences of working with information, their perceptions of user education and its impact on their essay work. The interviews were transcribed and analysed with Bruce?s (1997) relational model of information literacy.

Fodder to ruminants within agroforestry systems in Rwanda - species and management

Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.

Matematisk generering och realtidsrendering av vegetation i Gizmo3D

To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

Vad är meningen med värdegrunden? : Om svårigheten i att förena teori med praktik i värdegrundsarbetet i skolan

The topic of this essay is core value issues, how they are mediated in school and how they are practiced. I am investigating a problem concerning the existential worth of the core values-content for children, or in other words, the difficulty of reconciling the theory of the core values and their practice. This problem is portrayed by two stories. The aim of this work is to investigate how to combine the core values theory with its practice, in other words, make it meaningful. In my essay, I turn to recent research in the field to provide a background to my issue, and hereby further point to my problem.

Optimisation of a method for isolation of Clostridium difficile from faeces

Clostridium difficile is a pathogen for both humans and animals and is often associated with antibiotic-associated diarrhea. Recently, several human cases of C. difficile-infection with increased mortality and morbidity have been reported. In studies performed in different countries C. difficile has been found in meat.

En sjuksköterskas följsamhet till basala hygienrutiner : En studie utifrån Theory of Planned Behaviour

Background: Nosocomial infections pose a big threat to patient safety and increased costs for society. An effective way of preventing cross-infections is to apply hygiene routines. Studies show that compliance to hygiene routines is low while there's a lack of knowledge about the best way of improving it. Aim: To investigate whether a conversation based on the Theory of Planned Behaviour (TPB) could influence a nurse's compliance to hygiene routines and whether it could benefit the understanding of a nurse's compliance. Method: A quantitative and qualitative method was used in the study and included one nurse.

Användning av smärtskala på marsvin ? experimentell studie i klinikmiljö

Assessing and measuring post-operative pain in all animals is a challenge, but doing it in small mammals, for example guinea pigs, presents an even larger difficulty. Validated pain scales developed for use in dogs in clinical practice are currently available, but no such scale has been widely accepted for use in guinea pigs in the veterinary setting. In this experimental study, six guinea pigs that had undergone surgery and anaesthesia were observed for behavioural changes that could be associated with pain. The six guinea pigs were also given pain scores with the use of Colorado State University Feline Acute Pain Scale (CSU-APSF), a scale which uses both behaviour when not handled, body tension and response to palpation to evaluate pain intensity. The six guinea pigs showed a number of different behaviours, for example rigid posture, fixed stare and ?wet dog response? (the body is vigourosly shaken), that could be associated with pain.

En jämförande studie av fluiddynamiken för olika fluidiseringsmedium i en kallmodell av en 100 kW-anläggning för kemcyklisk förbränning

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
