Trioplanex International AB is a part of the group Trioplast Industrier AB, which produces packaging materials for the film and hygiene industry. The group is active throughout Europe, where most of the production is located in Sweden, with head office in Smålandsstenar. Operations in Landskrona consist of Trioplanex International AB and Trioplast Landskrona.Semi-finished articles consisting of paper cores, so called bobbins, give rise to a high amount of core waste in any form of core cutting. The objective of the report is to map out all core waste and illustrate the material flow with regard to present layout and equipment.In the beginning of the project an analysis of the current process was carried out with focus on the cutting equipment. A case study in the form of an improvement work took place in order to reduce the causes which had the biggest impact on existing machinery.Improvement proposals were discussed by the author together with supervisor, assigner and other parties involved.

Dokumentation av underhållssimulatorer för utbildning i vardagssäkerhet

At Forsmark nuclear power plant a new course called "education in everyday safety" has been started in an attempt to improve the safety culture. The goal is to spread the of expectations and approach the maintenance management has set, to all employees working at the plants. During the course, theory is mixed with practical tasks to reach a common view how work should be done to achieve safety for the plant and the people that work there.The practical tasks are done inside "maintenance simulators". They are built inside 20 ft containers which contains two dummy pipe systems. On the pipe systems some valves, a flow meter and a pump has been installed.

Implementering av Patientsimulator för Anestesimaskiner

In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.

Produktionslogistik, effektiviseringav materialhantering

Atlas Copco Tools is a world leading company in tool manufacturing. The productionin Tierp works hard to improve their assembly to maintain its position. This thesis isa part of their improvement efforts to be a more Lean production.The main focus for this thesis was to identify the material flow in the kanban system,which used to supply the assembly groups, focusing on the material flow to assemblygroup 9 and the assembly group 3. Group 3's material flow within the kanban systemwas perceived to perform better than the group 9. The handling of kanban materialand their working methods in the two groups was identify those differences whichaffected the kanban system.As an alternative material supply a study were done in kiting.

Effektivisering av marina containerflöden : en fallstudie på Bertling

Logistics is an important concept in the organizational context in which the planning of flows, services and products are treated. Logistics handles supplier management, supply of materials, production and distribution. The distribution of goods can be managed with different types of transportation depending on price and time aspects. The lowest transport cost for larger amount of goods is by maritime shipping. A common carrier used in transportation of goods is a standardized ISO- container.

Produktivitet vid stubbskörd :

Stump harvest could be found in the late 1970?s and the early 1980?s. And now when the prices on energy are high it has become an interesting topic again. This work has been conducted within Holmen Skog?s stump harvest testing in Norrköping.

Dyskalkyli : En kvalitativ undersökning om hur fyra pedagoger i specialpedagogisk funktion arbetar kring dyskalkyli

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

TT och utlandsbilden : En kvantitativ innehållsanalys av utlandsbilden i Sveriges största nyhetsbyrå.

The purpose of this study was to examine the foreign news flow in Sweden´s largest news agency TT. Since TT has an important position as a news provider to most of Sweden´s local and national news outlets, it was important to examine exactly what their news stories consisted of.The theoretical background of this study consist of theories of news values, agenda setting, dependency theory and the theory about the ?news shadow? a lack of coverage leads to.In our quantitative study we have looked at 506 articles taken from the TT news flow during two weeks In November 2013. We have studied which continents and countries the news origins from, who have supplied the text, the topics of the news, which one gets to speak in the text and what general tone the story has.The study shows that the supply of news follows the criteria of news values. It also shows that in some regions of the world the coverage is almost nonexistent.

Kemin bakom framtidens avgasrening : En studie av ureasönderfall under kvävgasatmosfär

The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.

Flow & sång. Att hitta närvaro, uttryck och att beröra

The aim of this study is to examine the collection One Thousand and One Nights (also: The Arabian Nights) from a european perspective, by comparing different european translations. The study focuses on three translations into Swedish from different periods of time and how the tales have changed in the translation process - depending on the prevailing line of approach and Western perceptions of Eastern standards. The thesis of the study is that Eastern culture, from a Western perspective, has been seen as exotic and different but not as a high literary culture and that this view has affected the translations into european languages. The study shows, among other things, that Western culture is many times considered normative in the translations and that the translators often give their own voices a prominent role, also that common Western notions of the East affects the translations.The word ?orientalism? is used frequently in the study and it refers primarily to the image of the Orient as it is described in Edward Saids' book Orientalism: as a Western construction whose main purpose is to strengthen its own conception of the Orient and thereby strengthen the Western identity as better than the Orient.

En diktaturs väg in i Informationssamhället Kina och World Summit on the Information Society

This masters thesis investigates the relation between China and the Information Society as it is manifested in the UN conference the World Summit on the Information Society WSIS. The first phase of this two-phase conference took place in Geneva 10-12 December 2003, with two documents, Declaration of principles DP and Plan of action PA, as main results. The information policy is central to an authoritarian rule in its efforts to keep control over the national identity. The thesis investigates the impact that the information revolution and Internet might have on the Chinese national identity through the acceptance of DP and PA in various aspects. With the use of the information science theories by Manuel Castells and Frank Webster, the vision of WSIS was compared with the Chinese information policy.
