IBS ischaracterized by abdominal pain/discomfort in combination with diarrhoea, constipation, or acombination of these. The etiology is unknown but it is believed that there are several factors thatcome into play. The disease cannot be cured, but there are ways to alleviate the symptomsthrough a variety of medicinal preparations and dietary treatment.

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

This paper deals with evaluating 3D-bootstrap for the mining company New Boliden in an attempt to revise their current method of calculating average gold riches in different areas. The purpose is to find one-sided 3D-bootstrap confidence bound of the average gold riches. There lacks well-defined theory behind using 3D-bootstrap, in this paper the variogram is used as an estimate of dependencies between the observations, and the block length is chosen to be higher than this estimate. In aid of this, a simulated data material is conducted to check the validity of 3D-bootstrap in a controlled area where the theoretical value is known. The results are inconclusive, and further studies are needed..

The Uppsala based company Q-linea develops procedures, instruments and systems for protein and nucleic acid analysis. The components in such an instrument are controlled by microcontrollers. Microcontrollers are computers in one singular chip that can be used in a wide range of applications such as cars, toys or in this case an analysis instrument. When developing a new instrument for biochemical analysis, Q-linea needed new software for controlling and communicating between the components in the instrument. The process of developing this software is the subject of this thesis.The project included research of microcontrollers and the components in the instrument.

This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink.

This report is written for a consultant networking company with the purpose to review the development ofthe company's remote connections from a user friendly and security perspective.This includes an investigation of the possibilities to consolidate existing authentication methods foraccessing customers. The problem lies in the amount of methods being used. Through case study wefound that smart cards, SMS-service, software and hardware tokens exist.The only method feasible from a security perspective is smart cards. Since the method is not commonlyused by the company's customers a standardization of it would be counterproductive.Also, the purpose of this report is to investigate how the ongoing internal development of the remoteconnection will affect the company's clients. Within this framework we have also verified a designsuggestion.We interpret, after the completion of the case study, that the internal development of the remoteconnection is marginally affected by legal perspectives.

Denna uppsats är skriven inom ämnet Företagsekonomi och omfattar 15 högskolepoäng på C-nivå på Institutionen för ekonomi vid Sveriges lantbruksuniversitet. Tanken bakom vår uppsats är att ge en bild av vad controlled traffic farming (hädanefter förkortat CTF) är, samt om odlingstekniken kan ge bättre lönsamhet i svenskt lantbruk. Förhoppningen är därmed att uppsatsen skall ge en grundförståelse inom ämnet. CTF innebär att permanenta körspår anläggs och att all fälttrafik sker i dessa körspår. Följderna av detta blir således att åkermarken mellan körspåren övergår till att vara mer lucker, eftersom lantbruksmaskinernas markpackning koncentreras till körspåren. Markpackning är ett av de stora problemen i dagens jordbruk och målet med CTF är att öka lönsamheten genom högre fältavkastning till följd av bättre markförhållanden för grödan. Studien utgörs av en jämförelse mellan konventionell plöjningsfri växtodling och odling med systemet CTF.

In this final thesis a rough description of aluminium extrusion is made, the importance of temperature of both the raw material and the extruded profile for a good profile quality. The difficulty in controlling these temperatures are discussed and attempts to increase the control are described. The attempts are basically made by controlling the furnace that is heating the raw material. This is done in a manner that the raw material reaches its final temperature shortly before it is extruded. An IR-camera at the press can be used for profile temperature measurements.

Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.

Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.

Our purpose was to research the new reform amendment" Lag om etableringsinsatser för vissa nyanlända invandrare", and whether the establishment of the reform is good and if it was a necessary amendment. For that reason, we have chosen to answer our purpose in these issues with this question formulation; how can the change of the law establishing operations influence the newcomers in the labour market, the problems the law intends to address, how the new change in the law is different from when the municipality "kommun" was responsible, and how the law can be discussed based on theories of social capital and weak ties. The method used in this study is from a adductive approach where the research is based on both empirical evidence and existing theory that interact between these two. The results that emerged in our work was that the newcomers within the labour market has been remote, the way the municipality?s addressed the problem did not work and the result of this was a new reform amendment, where a new participant established.

Today we can create digital 3D models which can be realised almost instantly through production methods such as 3D printing and computer controlled milling.What if this same technology could be applied to the development and construction of terrain parks?With snow as the material tools could be developed using similar principles to design and sculpt the surface, only on a larger scale.How would terrain park designers adapt their process to use this new technology? In this Industrial design thesis I explore how the ideas of the terrain park designer can be expressed through such a system with focus on the designers knowledge and skill without the need to learn complicated 3D programs.Sketch, create, ride. .

This report is based upon an experimental study of exit sign luminescence in different environments. The purpose is to evaluate the lowest luminescence of an exit sign, based upon Swedish regulations. Scientific experiments have been conducted in a controlled environment, where exit sign luminescence was graded by an evaluation group. The results of these have been verified by similar experiments that took place in two department stores. The final result of the study is guidelines for appropriate exit sign luminescence in different environments..

Telefonrådgivning kräver ett kvalificerat handläggande där sjuksköterskan på kort tid ska kunna etablera en god vårdrelation med patienten trots att den visuella kontakten saknas. Förutom kunskaper inom medicin krävs det att telefonsjuksköterskan har en god förmåga till kommunikation och visar respekt och empati för patienten. Efterfrågan på telefonrådgivning ökar och detta ställer krav på specifik kompetens hos sjuksköterskan. Vi har därför valt att beskriva vad som kännetecknar sjuksköterskans arbete med telefonrådgivning för att få kunskap i om hur vi i vår profession kan bli bättre på att ge råd via telefon. Det har gjorts i form av en litteraturstudie med grund i analys av kvalitativa artiklar samt en kvantitativ artikel.
