Dynamisk massbalansmodellering av fosfor i Östersjön
During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.
Användning av könssorterad sperma i nötkreatursaveln :
Almost for as long as there has been breeding on bovine species, there has been a wish to have a higher proportion of offspring of either one or the other gender. In dairy cattle, heifers are more valuable, while in beef stock bulls are preferred. Semen is sorted based on the difference in DNA content between the X- and Y-chromosome in the genome of the sperm. X-chromosomes contain on average between 3,70 to 4,22% more genetic material than the Y-chromosome. Commercially it is the method of flow cytometry that is being used, which is always under improvement.
Utredning av alternativa distributionssystem för Holmen Paper
Holmen Paper is one of Sweden?s leading manufacturer of paper, with two Swedish production facilities located in Norrköping and Hallstavik. The European continent constitutes the company?s largest customer base which makes the company?s distribution system an integral part of the business. Historically, much of the produced paper has been transported by vessels, as vessels allow large volumes of goods and deliveries to markets which are difficult to reach with other modes of transportation.

Kemisk karaktärisering samt nedbrytning av process- och avloppsvatten vid SCA Ortvikens pappersbruk
During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.
Implementering av lean i ett gjuteri med låga volymer och hög variation
Valmets own foundry in Karlstad has during a long period of time had problems being profitable. The goal today is to turn this around. Today there are three different productionlines; engine blocks, Yankeecylinders and components for the wind turbine industry. This master thesis has focused on examining if value stream mapping is a useful tool to use in a foundry, and therefore outside the typical manufacturing industry. The target has also been to evaluate if there is a possibility to improve the flow in the foundry and also the results.During the 20 weeks this work has been done at the foundry data has been collected and analyzed.
Informationskvalitet: informationssökares syn på kvalitet
The aim of this thesis is to examine how different kinds of information seekers are evaluating information quality in the information flow online. To address the problem stated, qualitative interviews were carried out with a librarian as a reference person and a group consisting of journalists and scientists. The result of the study implies that the reference person is well aware of the strategies employed by her in the search process. However, the respondents are not aware of the strategies they are actually using. An explanation is the respondents lack of education in information seeking.
Järnvägens banutnyttjandeplanering : nuläge och förbättringsförslag
The Swedish National Rail Administration has changed in the past decade, from its origin after a less dramatic separation from the Swedish State Railways to becoming an authority with its own identity. Today the National Rail Administration is a large organisation with several different departments, each with its own unique function. To operate train services the railway needs to be ?in shape?, leading to a need for maintenance, reinvestments and new investments. For this purpose, the National Rail Administration carries out public procurement where contractors, who are able to perform maintenance and new construction, submit tenders.
Självförvållad sinnesförvirring : Konsekvenser av att fingera tillräknelighet istället för uppsåt vid gärningar som begåtts under självförvållad sinnesförvirring
This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.
Utskrivning från sjukhus ? En studie av utskrivningsprocessen vid en medicinklinik
Introduction: The interaction between different care facilities and professions is important in the care of older patients. Patients do not always get enough time to recover and often have a continued need for care. A discharge process of good structure in which the patient and relatives are participating and the continued need of care is assured is of importance in care of older patients.Objective: The overall purpose of this study is to compare the discharge process for patients over 75 years old admitted to a emergency medicine ward respective a emergency medicine ward with geriatric focus at a medicine clinic, to compare discharge process between these wards and evaluate the patients situation at home after discharge.Methods: A survey of medical records with a protocol and a telephone survey have been performed. Data was analyzed with descriptive and analytic statistic. Patients at the medical wards MAVA and care unit number 21/34, which are 75 years or older and are discharged to their own home, within the municipality of Göteborgs stad, in Sweden, are included in this study.Results: The discharge process differed between medicine wards with emergency medicine and geriatric focus.
Reduktion av föroreningar i processvatten från en äggfabrik i Brasilien : Kväve- och fosforrening i anlagda våtmarker.
A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes. The wastewater from the factory consistedof process water from manufacturing and water used for cleaning, no stormwater or sewagewater entered the system. Tests were taken three times a month from October 2013 ?til April2014.
Beslutsfattande inom Produktutveckling : Kartläggning, analysering & vidareutveckling av PPM process på ett medtech företag
The number of ideas at innovative companies usually exceeds the amount of available human ormaterial recourses, this include ideas for development of new products. Since they are not able to doeverything they want to do they have to choose between ideas to develop new products. This includesthe decision on when to start, stop or kill a project as well as the thought process of prioritizing betweenongoing and potential projects.Project Portfolio Management (PPM) is an organizational process, with the purpose of systematicallyorganizing and running the activities that aim to evaluate, select and prioritize ideas and projects fordeveloping new products. PPM include four major goals to be fulfilled; Maximizing Value of thePortfolio, Achieving a Balanced Portfolio, Achieving a Strategic Alignment and Running the RightNumber of Projects.The purpose of the thesis was to develop a more visual and formal PPM process for the early stages inproduct development in one department at St Jude Medical AB, Sweden.The thesis was conducted by following a methodology known as Process Modules. The methodology isan approach for developing a PPM process that fits a specific company.

Har muren fallit? En studie av policynätverk inom infrastrukturprocessen i Skåne
The creation of Region Skåne, and the transfer of the development responsibility from the national administrative country board (Länsstyrelsen) has given the state new challenges. New structures have grown between Region and State, and also between different municipalities. These can be characterized as Policy-networks, and the goal of this study is to analyze the planning process of the regional infrastructure with these theories.This is a qualitative study of the infrastructure process in Skåne, and the actors that acts within this process. It has been studied with the eyes of the theories of Governance and Policy-networks. The main method to collect material has been through interviews with different actors within the process, and very little written material has been used.
Kvalitetsförbättringar och Emballageinstruktioner
This report is the result of a thesis carried out at the Department of Innovation, Design and Technology (IDT), at Mälardalen University on behalf of ABB AB Machines.The year was 1988 when ASEA and Brown Boveri formed a joint venture under the name ABB (Asea Brown Boveri).We perform our thesis at the division Discrete Automation and Motion where they primarily develops, manufactures and sells synchronous and asynchronous AC motors and generators.The main purpose of this thesis was initially to write a general packaging instruction, but the priority changed to develop more specific packaging instructions for Rotors, Stator gables, Bearing support and Outer Cover (plates) instead.The work started off to deal with a problem about that the staff had to start its work to grind away rust on the stator gables due to those stored outdoors. The result was mainly an investment in a new gable rack so that the material can be stored inside, as well as a packing instruction as it was originally intended.The problem on the bearing supports were that the staff thought it was demanding and difficult to clean them from the rustproofing they were greased in. If it is not possible to remove all rust protection it can cause the paint to not attach properly. After having compared with similar articles a test were done to order a pair of bearing supports without corrosion inhibitor, which gave good results. This initiative also set in motion a process to do the same for more different items.For special pallet, a survey were made of the process with two different VSM and a calculation of how much ABB would earn at ordering more special pallets than getting the material delivered on the A-pallets.
