This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

Background: Pain can be a constant problem in many older people's daily life, associated with particular physical and social disability, depression and poor quality of life. Dementia diseases are often associated with old age. Communication difficulties are one of the consequences of the disease, which clarifies the role of nursing staff in detecting and assessing pain. Objective: The aim was to compile knowledge about how nursing staff can identify pain in people with dementia. Method: A systematic literature review, where data were collected through manual and database searches.

This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..

Abstract Aim: Since there is a lack of research based educational interventions concerning the relationship between coaches and young athletes, the aim of this study was to implement and examine the effects of sport psychology intervention for coaches in a track and field club. The research questions were: What are the effects of an educational intervention for coaches, with focus on a motivational climate, on: A) the coaches´ coaching approach B) their athletes´ goal orientation and C) their athletes´ perceived competitive anxiety?Method: The coach education stretched over two months and consisted of four two-hour lessons with focus on motivational climate, goal orientation and sport anxiety. Six coaches (three females, three males), aged 38-52 (M=44.33 years, SD=4.84) and their 59 athletes (27 males and 32 females) aged 12-14 (M=13.10 years, SD=0.82), participated in the study. A control group of 35 athletes (10 males and 25 females), of the same age (M=13.46 years, SD=0.70) and with similar demographic data, was also recruited.

Heat and power stations are often in need of optimizations. A simulation model is a tool for findingways to optimize the plant. The scope of this diploma work is to develop a simulation model ofBoiler 5 at Mälarenergi AB. Boiler 5 is a circulated fluidized bed boiler that was taken into service inyear 2001. Among the included parts in the boiler are cyclone, convection part andINTREX-chambers.

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

Sömnen är livsviktig för alla människor eftersom det är den tid då kroppen återhämtar sig och behovet av sömn blir därför speciellt viktigt vid sjukdom. Forskning har visat att sjukhusmiljön inte alltid är optimal för att främja sömn, något som vi själva också upplevt under kliniska studier. Syftet med studien var att klargöra vilken betydelse sömn har och hur sömnen kan förstås i relation till hälsa och välbefinnande för patienten i sjukhusmiljön. Studien är en begreppsanalys där sömn har sökts och analyserats i lexikon, vetenskapliga artiklar och facklitteratur. Resultatet visar att sömnen är den tid då kroppen samlar kraft och immunförsvaret byggs upp.

The number of persons with problems of abuse or addiction seeking care has increased during the last years in Sweden. Recent international studies show stigmatizing attitudes among nursing staff, which affect the treatment and care negatively. The purpose of this study was to describe experiences among nursing staff of treating persons with problems of abuse or addiction at an emergency department. The participants were six nurses and one assistant nurse who worked at an emergency department. The interviews were analyzed through qualitative content analysis.

Diabetes typ 2 är en kronisk sjukdom som ständigt ökar. Syftet med denna litteraturstudie var att beskriva patienters upplevelser av att leva med diabetes typ 2.

Resultat som framkom i studien var svårigheter med att ändra livsstil beträffande kostvanor, hantering av medicinering och fysisk aktivitet.

The purpose of this two years master thesis is to examine the potential benefits of using bibliotherapy on elderly Finnish immigrants residing in Sweden and living in geriatric care. The basis of the study is a four week long bibliotherapeutic project implemented at a nursing home for Finnish-speaking people in Stockholm County.Participants were men and women spanning in age from 70 to 90 years old. Common for all the participants was that they had lived their entire adult life in Sweden, their only language was Finnish, and they had the diagnosis of dementia. The study examines the bibliotherapeutic model of Arleen McCarty Hynes and Mary Hynes-Berry, as well as Inger Eriksson?s approach for the use of bibliotherapy in nursing homes and hospices.The empirical analysis is based on field notes from the bibliotherapeutic sessions and from interviews with librarians and nurses involved in the project.

Background: Encounters between patient and health care have been shortened and fragmented. Times when the patient is in the continuum of care is related to how well the patient feels confirmed in the meeting with his/her carers. Aim : The aim of this study is to highlight skills that nurses use to provide good care relationships with patients in the ambulance and emergency room. Method: A literature review was done. Search for articles was conducted in the databases Cinahl and Pubmed.
