Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas. The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.

To reach health and wellbeing, despite a disease as rheumatoid arthritis, the patient needs help to manage and cope with his situation. The caregiver?s task is to give this support. The aim of this study was to illuminate how patients with rheumatoid arthritis experienced the relationship to the caregivers in the ?rheumatic-team?, and the participation in this team.

Hot och våld förekommer inom ambulanssjukvården. Ambulanspersonalen befinner sig ofta först på plats vid olyckor eller brottsplatser för att ta hand om sjuka och skadade människor. Vanligtvis är ambulanspersonalen ensamma och vid en del situationer förekommer missbruk eller andra sjukdomstillstånd, vilket kan göra patienterna aggressiva. Syftet med studien var att undersöka förekomsten av hot och våld mot ambulanspersonal i Sverige och hur samspelet mellan vårdare och patient påverkas, samt hur ambulanspersonalen påverkas av hot och våld på sikt. Med hjälp av enkäter samlades data in.

The purpose of this litterature review is to illustrate the nursing care to patient with chronic pain. As a theoretic frame for this study we choose Aron Antonowsky. The results of this study are based on 8 scientific articles. The findings are presented in main categories and ideas. The findings show that chronic pain is a multidimensional phenomenon that influences peoples quality of life in a physical, psychological as well as social way.

Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.

The prehospital management of patients with acute myocardial infarction (AMI)now includes 12-lead electrocardiogram transmission directly from the ambulance to hospital.If the ECG shows ST-elevated myocardial infarction the patient should be transported directlyto a hospital with capability for percutaneous coronary intervention (PCI).                                               Aim: The aim of this study was to describe how ambulance nurses experienced the prehospital management of patients with AMI who are transported by ambulance directly to hospital for PCI.                                                Method: Semi structured interviews were conducted with eight ambulance nurses. Data were analysed using qualitative content analysis. The categories that emerged were: Use ofcompetence, Responsibility and Insufficiency. Result: The result showed that the ambulance nurses felt secure when they cared for patients transported directly to PCI. The nurses assessed the patient and decided how he or she should be cared for.

Det är sedan länge känt att sömn på sjukhus är ett viktigt grundläggande behov för tillfrisknad. Det finns en bristande uppmärksamhet från sjukvårdpersonal om sömnproblematiken som finns på sjukhus, och miljöfaktorer som kan påverka patienters sömn negativt. Dessa faktorer kan förbättras om problemen identifieras och åtgärder vidtas för att förbättra sömnmiljön. Syftet med studien var att belysa miljöfaktorer som kan påverka patienters sömn på sjukhus. Studien är genomförd som en litteraturstudie där 21 vetenskapliga artiklar samlades in och granskades.

This paper aims to explore the possibility of reading the Temple cleansing stories of John and Mark through Bruce J Malina?s honor/shame model, as E. Randolph Richards do. The analysis searches in John?s and Mark?s Temple cleansings for the presence of the notions of honor and shame, as Malina uses those concepts in his model.

Inom palliativ vård är en professionell interaktion väsentlig såväl för sjuksköterskan som för patienten och dennes närstående. Interaktionen utgör grunden i omvårdnaden och medför att patienten upplever trygghet. Syftet med studien var att belysa interaktionen i mötet mellan sjuksköterskan, patienten samt dennes närstående inom palliativ vård. Metoden som användes var litteraturstudie. Resultatet visar, att förutom att interaktionen mellan sjuksköterska, patient och dennes närstående ansågs utgöra basen i omvårdnaden så var det väsentligt att sjuksköterskan med hjälp av interaktionen förmedlade stöd, bekräftelse och respekt.

Abstract The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment. In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.

 IAS 40 allows two methods of valuation for investment properties, fair value model and cost model. The purpose of this paper is to investigate what drive property companies to disclose their investment properties at fair value. In order to understand their choice, we use accounting choice theory and the three factors this theory describes, information asymmetry, allowing opportunism and agency costs. To answer our purpose, we have from a qualitative approach performed semi-structured interviews with respondents from five of the largest listed property companies in Sweden. The results suggest that firms have chosen the method that is most effective in the valuation of investment properties.

Purpose: We will understand and explain Dell?s value gap through an extended intellectual capital theory. This will be done by deriving the value to the different parts of the intellectual capital value scheme. We will also use value scheme to describe the ongoing strategy shift. Methodology: The qualitative method and an abductive reasoning have been employed during the progress.

The following study explores the relation between psychosocial work environment and individual health. The purpose is to examine how female employees in the occupational health sector experience their own psychosocial work environment, focusing on different influencing factors in both the workplace and their private life regarding the employees own health. The study applies a hermeneutic approach in which qualitative interviews constitute the empirical data. Previous research on this particular subject has focused on the following themes: the combination of work-family life, demand/control model and flexibility in the workplace in relation to health and stress. The theoretical framework used in this study integrates relevant concepts, specifically SOC, poor leadership and flexibility.
