The present study is embedded in the research field of Personal Information Management (PIM) and its goal is to contribute to this research area by showing information management aspects in untraditional contexts, as in the social networking site Twitter. The aim and purpose of this two year's master thesis was to investigate the beha-viour of librarians within the context of Twitter. The objectives of this thesis focus on the query of the informa-tion management aspect of Twitter, and on the investigation into whether Twitter offers the possibility to reach a state of flow while using it, as well as inquiring into the relationship between Mihaly Csikszentmihalyis flow theory and PIM. The theoretical framework of this thesis is centred upon the flow theory and the conditions that are necessary to reach a state of flow. To fulfill the purpose of this thesis a directed content analysis is applied as an investigative method, where its in-depth research aspects will be applied upon the empirical material, which contains 429 tweets.

Det här arbetet handlar om flow och hur begreppet samverkar med olika aktiviteter i våra liv. Bakgrunden till flow förklaras inledningsvis i kapitlet om teoretisk bakgrund och sätts senare i relation till inre förändring, socialt samspel, fysisk aktivitet, kommunikation, samt pedagogik. Syftet med arbetet är att ge svar på hur flow kan användas i undervisning. Som metod för datainsamling har jag gjort en gruppintervju med fyra lärare aktiva vid Musikhögskolan i Malmö. Gruppintervjun fungerade som ett vardagligt samtal mellan fyra personer och resultatkapitlet är sammanställt i sex rubriker: Introduktion; Personernas uppfattning om flow; Vägar till flow och hinder på vägen; Gruppflow; Flow, kvalitet och kommunikation; samt flow och undervisning.

Abstract Title: A messy story ? a case study of Secorocs process flow of DTH-pipes Presentation date: 2010-06-02 Course: Bachelor thesis in businessAuthor: Kristoffer ForsmanAdvisor: Kjell GustafssonKeywords: Management control, process control, lean production, process flow analysisPurpose: The purpose of this bachelor thesis is to develop an overview of the process flow for a specific product, and with the help of this mapping based on a lean production philosophy show possible improvement proposals and how these can lead to a more efficient process flow.Methodology: I have used a case study of Secorocs DTH-pipes and my primary data are gathered through interviews and observations. I have used theoretical framework to establish a process flow analysis. This is to obtain data on process activities and whether they are creating value or not. This leads to a current mapping of the situation in Secoroc on DTH-pipes and then analyzed and suggestions for improvement are developed.Conclusions: That by using the above mentioned mapping of process flow of DTH-pipes, problem areas could be illustrated.

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.

The effects of dexmedetomidine and butorphanol sedation on skin reactivity during intradermal testing in healthy dogs were evaluated. The effects of dexmedetomidine and butorphanol were compared to medetomidine, a sedative agent having scientific proof of not interfering with skin test reactivity, in a randomised, double blind, cross over study performed on 8 adult dogs. The dogs were sedated with medetomidine (Domitor vet.®, 0,01 ml kg-1) intravenously, or dexmedetomidine and butorphanol intramuscularly (Dexdomitor vet.®, 0,01 ml kg-1; Dolorex vet., 0,01 ml kg-1) after which they received intradermal injections of positive control solutions (histamine 0,1 mg ml-1, 0,05 mg ml-1, 0,025 mg ml-1), a negative control solution (0,9 % NaCl) and allergen extract (Dermatophagoides farinae, Cladosporium and Artemisia vulgaris). After a wash out period the trial was repeated with a reversed sedation protocol.Skin reactivity (wheal size, induration and erythema) and quality of sedation (immobilization, response to stimuli and injections as well as over all working conditions) were evaluated. The combination of dexmedetomidine and butorphanol provided reliable, good sedation and analgesia without adverse effects.

Ala sawmill in Ljusne, Hälsingland, has increased its flow through the sawing plant during the last couple of years. The problem now is the sorting plant, as this part of the mill is now slower than the rest. A close analysis of the sorting plant was therefore necessary to be able to increase the flow through. The aim of the project was to find solutions that can lessen downtime and increase flow. The goal was to increase the flow from 650 to 925 logs through the sorting plant per hour.

The term euthanasia is derived from the Greek terms eu meaning good and thanatos meaning death, "good death". The penetrating captive bolt is an effective method of euthanasia, when use of drugs is inappropriate. The horse becomes immediately unconscious and falls to the ground. First after the blood is emptied from the body the horse is dead. The use of injectable euthanasia agents is a rapid and reliable method of performing euthanasia. The aim is to stop the flow of oxygenated blood to vital organs and tissues. The muscle relaxants may be used either in combination wih or following an anaesthetic dose of barbiturate, their use use as a sole agent is totally inhumane.

The goal of this study is to examine what five teacher?s impression of the teacher?s role is in their previous years. How important the ?joy at work? is in relation with the educational progress? And what aspects that contributes to the? joy at work? and what obstacles that stops them. The essay will also go through the concepts of a teacher role, with connection to the theoretical perspectives of Csikszentmihalyi?s Flow and Antonovsky?s Salutogenesis (KASAM).The method I used was interviewing five teachers and I used Larsen?s chapter of ?content analysis? as a basis, I also used Flow and KASAM as theoretical references in my analysis.

There is something magical about shoes?They can create an irresistible desire or be the one thing that we want to get rid of the most at the end of a long day. When people by shoes the chose more out of appearance rather then comfort. The result is a fact. The feet feel tired and soar after a couple of hours and the only thoughts are about the aching feet that firmly object to the way there being treated.

Syftet med detta arbete är att simulera ett värmesystem i COMSOL Multiphysics, Pipe Flow Module, Non-Isothermal Pipe Flow som innehåller ekvationer och randvillkor för att modellera inkompressibel strömning och värmeöverföring i rör.Data om processen och dess komponenter har samlats in från industrin där arbetet är utfört och i vissa fall modifierats för att bättre beskrivas i programmet.Utifrån insamlad data har en modell byggts upp och två simuleringar har gjorts. En stationär för starten av systemet, den har sedan legat till grund för en dynamisk som simulerar förloppet från start till normaldrift.Tiden det tar för det aktuella fallet att nå drifttemperatur är 16 timmar. En felströmning upptäcktes samt att en av pumparna inte kommer att klara en start från 20 °C..

Background: Today there are high claims on organizations to show a positive economic view. To satisfy the demands and expectations from interested parties it is very important to carefully plan the companies tied up capital and cash flows. Purpose: The purpose with the thesis is to describe what actions organizations take to resolve the conflict between showing a positive cash flow and the need to tie up capital.The purpose is also to explain the different factors that must be considered when making decisions regarding cash flow and capital tied up. Method: A qualitative study of the actions and factors wich must be considered when decisions in swedish construction companies are made regarding cash flow and capital tied up. Results: A model of the factors and actions that affect cash flow and capital tied up in projects.

The equine hoof is often manipulated in purpose to achieve a better stride or to reduce the weight on damaged tissue. The living tissue in the hoof can?t store energy as glycogen and is therefore depending on a continuous supply of glucose for its energy production. The purpose of the study was to determine if wedging (i.e. elevating) the heel could influence the hooves glucose and lactate consumption/production. Five standardbred horses were trained to trot on a treadmill without getting physical or mentally tired.

The Volvo Trucks plant in Umeå is a highy complex manufacturing facility where the same production line handles a variety of different models. This require flexible and agile processes with high quality standards. This thesis studies the flow of material through a production line and how Volvo can use their existing manufacturing monitoring system to optimize the flow of materials.The goal with the thesis is to identify eventual problems with the flow of materials and to deliver a few proposals on how the production line can improve its productivity. The theory of LEAN, Just-In-Time and Supply Chain Management serves as the scientific reference to this project. By analyzing the flow of material, performing interviews and observing the processes a few problems are identified.

Equine metabolic syndrome (EMS) it?s a clinical condition that includes obesity, regional adiposity, insulin resistance (IR) and laminitis. A similar syndrome exists in human medi-cine, the metabolic syndrome (MS), were systemic hypertension also is a prominent fea-ture. The systemic hypertension seen in humans with MS is partly due to a vascular endo-thelial dysfunction with an enhanced endothelin-1 (ET-1) mediated vasoconstriction. There are indications that systemic hypertension might be a feature in EMS as well but if ET-1 is involved in the development of the systemic hypertension in horses is not known.

Hur kan svårighetsprogression användas i skapandet av Puzzlehunts med syfte att uppnå en ökad upplevd känsla av flow hos spelaren? Denna frågeställning behandlas i uppsatsen och problemet som måste lösas är hur man kan bygga upp en ackumulerad kunskap om något vars syfte är att hela tiden tvinga dig att hitta nya lösningar på problem. I mer traditionella spel kan upprepning lära spelaren hur spelmekaniken fungerar. I puzzlehunts kan upprepning av spelmekanik inte användas eftersom målet för varje pussel är att hitta mekaniken som löser problemet. Uppsatsen visar att man genom inlärning av hur man skall tänka för att hitta lösningarna till pusslen kan bygga upp en ackumulerad kunskap hos spelaren och därmed även ha en svårighetsprogression och öka upplevd nivå av flow hos spelaren..
