Mathematical Modeling of Blood CoagulationPerdomo, Joana L 01 January 2016 (has links)
Blood coagulation is a series of biochemical reactions that take place to form a blood clot. Abnormalities in coagulation, such as under-clotting or over- clotting, can lead to significant blood loss, cardiac arrest, damage to vital organs, or even death. Thus, understanding quantitatively how blood coagulation works is important in informing clinical decisions about treating deficiencies and disorders. Quantifying blood coagulation is possible through mathematical modeling. This review presents different mathematical models that have been developed in the past 30 years to describe the biochemistry, biophysics, and clinical applications of blood coagulation research. This review includes the strengths and limitations of models, as well as suggestions for future work.

A model for material handling improvements when using automated storage systems: A case study / En modell för förbättringar av materialhantering genom användandet av automatiserade lagersystem: En fallstudieThongmal Larsson, Marie January 2010 (has links)
The purpose of this thesis is to create a model of how to organize the placements of articles in an automated storage system in order to reduce time and cost related to the extractions. The model was developed during an investigation at a case company, and a comprehensive study of the material handling identified bottlenecks, whereof one was chosen to be further investigated: the automated storage system. The automated storage system is newly installed equipment, which required new working methods to be incorporated to the already existing working environment. The ABC-analysis was used in order to motivate how the articles should be placed in the automated storage. The goal for the new way of handling material was to put as little effort as possible on time related to the extraction of material. This due to the realization of material handling processes being a huge contributor to waste activities. This resulted in the development of the model and the suggestion that is given to the case company is to place the most frequent extracted articles close to the users. However, advantages must be held against disadvantages of rearrangements since the material handling will not be eliminated totally due to smaller improvements. / Syftet med denna uppsats är att skapa en modell för hur man ska organisera artikelplaceringar i ett automatiserat lagersystem för att reducera tid och kostnad relaterat till uttag av material. Modellen skapades genom en undersökning på ett fallföretag, en omfattande studie av materialhanteringen identifierade flaskhalsar, varav en valdes för fortsatt undersökning: det automatiserade lagersystemet. Det automatiserade lagersystemet är en nyinstallerad utrustning, som kräver att nya arbetsmetoder ska inkorporeras till den redan existerande arbetsmiljön. ABC-analysen användes för att motivera hur artiklarna ska placeras i det automatiserade lagret. Målet för det nya sättet att hantera material på var att så få insatser som möjligt skulle användas för uttag av material. Detta pågrund av insikten utav att materialhanteringsprocesser är en stor bidragande slöserifaktor. Detta resulterade i modellen och förslagen som ges till fallföretaget är att placera de mest frekvent använda artiklarna nära användaren. Emellertid så måste man väga fördelar mot nackdelar av en förändring eftersom materialhanteringen inte kommer att elimineras helt pågrund av mindre förbättringar.

Att spara eller inte spara? : En kvantitativ enkätstudie av informationslagringssystem för vetenskapliga artiklar / To Store or Not to Store? : A Quantitative Questionnaire Survey Study about Information Storage Systems for Scholarly ArticlesHäusner, Eva-Maria January 2012 (has links)
Abstract Purpose This thesis aims to focus on how master students administer scholarly articles after they have found them. The purpose of the study is to detect how and to what extent people administer their articles from a personal information management-perspective (PIM). Method To answer the research questions, a web-based questionnaire survey was distributed which was announced to around 2,000 master students from different universities in Sweden. Most of the items in the survey focused on individual storage methods. The respondents were asked to rate the frequency of their different information administration behaviors on a seven level Likert-type-scale. Subsequently, items concerning specific information administration behaviors were posed, followed by questions on the respondent's sociodemographic status. The results were based on overall 316 answers. Analysis The quantitative data was analyzed using non-parametric tests such as Friedmans-test, Kruskal-Wallis-analysis, Wilcoxon-Signed Rank-test, Mann-Whitney-U-test and Chi-square-test with the statistical computer program SPSS. Findings The findings generally confirm that the majority of the surveyed graduate students are using scholarly articles. Regarding their information management, it is as usual to store the whole article as it is to store the reference. Further it is more common to choose electronic storage methods for articles and references than to use physical methods. The results highlight that most of the students use several method types and use them to varying extent. Neither age, computer skills, duration of study or satisfaction with their way of information storage influenced the quantity of used methods. Regarding specific handling, the storing of article copies on the computer’s hard drive were most frequently used. The respondents preferred furthermore to read the articles on a screen rather than printed paper versions. The influencing factors of gender, age, computer skills, subject discipline were affecting the choice of methods. General conclusions about these influencing factors are, however, complicated by possible occurring confounders. Moreover, the method types were used to different extents depending of subject discipline. Originality/value Most previous PIM research is concentrating on how people store information in general. The dealing and administrating with specific types of information are, however, rarely discussed. In the context of scholarly articles did research predominantly focus on seeking structures and reading patterns. The step between finding and reading an article has so far not directly been addressed in academic research. The study therefore is unique in addressing information storage systems of scholarly articles on such a large scale. Knowledge about storage patterns will help journal publishers and librarians to design more targeted solutions for journal systems and improve services like courses in information seeking. Paper type Two years master’s thesis

Nyhetsjournalistik : En studie om Aftonbladets nyhetsjournalistiks möjligheter att leva upp till objektiv samhällsgranskning / News journalism : A study of the journalists at the newspaper Aftonbladet opportunities to live up to objective scrutiny of society.Mattsson Ottosson, Margareta, Tuomi, Topias January 2010 (has links)
The purpose of this study has been to find out what possibilities the journalists at the newspaper Aftonbladet have to live up to the proposed ideas and values that defines journalism, as well as how these values are presented to the readers. With this as a starting-point we have studied what kind of society Aftonbladet presents to its readers as well as how this society is supposed to work and also what it`s like. To be able to answer this question we have first researched through theories and earlier studies, literature about journalism, media science, semiotics, history and laws. With the help of the investigation we found fitting tools to perform the analysis. With the theory as groundwork we have, through the qualitative approach analyzed seven news articles from seven Aftonbladet newspapers during one week. Our study shows that the Afonbladet’s journalists have not been able to present occurrences in society in a correct and impartial manner - because they exaggerate insignificant details and neglect to show real attention to serious societal structures by using sensationalism, dramatization and a very superficial approach to the stories that they are conveying. We have also been able to establish that it is impossible for journalists to follow up and live up to the ideals of journalism. Not only that, it’s also impossible for them to live up to the ideals that the Aftonbladet as a newspaper has assigned for itself. A probable explanation for this is that the journalism field is characterized by high productivity and demands that the news are supposed to be easily understood and have a specific news value. All of this combined amounts to that a lot of times the journalism becomes accentuated, one sided and simplified, all to lure readers every day because Aftonbladet’s main income comes from single copy sales.

A Content Analysis Of The Security Dimension Of The Turkish Accession To The European UnionSayin, Ayse 01 July 2008 (has links) (PDF)
This thesis aims to analyze the security relations between Turkey and the European Union within the context of enlargement. In this framework, firstly, the historical background of the changing dynamics of their bilateral security relations is studied by focusing both on the Cold War and the Post Cold War periods. In this historical study, more emphasis is put on the Post Cold War period where the changing security understandings of both Turkey and the EU, major developments leading to adoption of new mechanisms by both actors and their impact on their security relations are analyzed. Secondly, after evaluating the importance of security in the European integration and enlargement processes, the security dimension of the Turkish accession, appearing in the official enlargement discourse of the EU actors and in the articles of the leading European think tanks&rsquo / scholars is examined via the use of content analysis method. Following this study, a critical analysis of the given speeches and articles is made. In the last part, the different security roles ascribed to Turkey by the EU actors and scholars in the related speeches and articles are discussed within the framework of Turkey&rsquo / s accession process. Accordingly, it is argued in this thesis that although Turkey&rsquo / s significance for European and regional security is accepted by the EU actors and scholars, this is not properly reflected on its accession process.
