In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.

The task to this thesis has been to create an application, Katana-databas 1.0, for analysing c-code. The generated output gets stored in a data structure which content in the end of the program run gets written in a textfile which gets used by Katana. It's a tool for reverse engineering, developed by Johan Kraft at Mälardalens institute.Katana-databas has got the following limitations. (1) It can only handle preprocessed files, meaning it doesn't contain any rows beginning with "#". (2) Only complete files can be handled.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

This essay concerns the Celts during the Iron Age, and their ritual practice in human sacrifice. The method applied is an eclectic historic-critic reading of the few classical sources that exist together with archeological material and scholars conclusions of literal sources and archeological material. The hypothesis is that human sacrifice in the Celtic realm not is to be seen as a primitive act of violence, but that it filled a social function to preserve society and the Celtic way of life.The question this essay strives to answer is Which function/s do human sacrifice fill in a Celtic context during the Iron Age? The question is analysed with the aid of Radcliffe-Brown?s and Catherine Bell?s theories on ritual, as well as Malcolm Chapman?s postmodern ideas of the conception of the Celtic. The conclusion of the essay is that the prime functions of Celtic human sacrifice are to preserve society and the Celtic social way of life, combined with an aim to eliminate disturbing elements in that same society, such as crime and individuals who did not fit in to the social community..

Lek är en erkänt viktig del i barns utveckling men det nämns sällan vad för betydelse den har för vuxna. I detta arbete har jag utgått från att lek är något att ta tillvara på och uppmuntra i livet. Jag har också utgått från att leken inte alla gånger kommer av sig självt utan att den kan behöva uppmuntras. Jag försöker i det här arbetet få ett grepp om vad lek har för betydelse i vuxenlivet samt vad det finns för positiva aspekter med leken. Jag har undersökt hur vi idag ser på lek bland vuxna och vad det finns för olika ansatsningar till att få in mer lek i vuxenvärlden. Genom teoribildning och två platsstudier har jag analyserat vad det finns för olika aspekter som bör tas hänsyn till vid planerandet av en lekfullmiljö riktad till vuxna, exempelvis särskilda inslag eller element som uppmuntrar till lek. Det finns idag flera forskare och organisationer som förespråkar och jobbar för att människor ska inse värdet av lek. Dels genom att upplysa om värdet men också med att uppmuntra människor genom olika initiativ till att leka mer.

Studiens syfte var att med neuropsykologiska utredningsverktyg undersöka exekutiva funktioner hos allsvenska fotbollsspelare samt division 1 spelare. Även sambandet mellan spelarnas exekutiva funktioner, gjorda mål och assist undersöktes. 57 herr- och damspelare testades. Elva kliniska utredningstest användes. Resultaten visade att de allsvenska spelarna hade signifikant bättre kapacitet på vissa exekutiva funktioner än spelarna från division 1.

Because of my interest and experience within the field of children and teenagers with an antisocial behaviour and who are acting out I wanted to devote my essay to researching these children through the perspective of the teachers. In this essay I, therefore, interviewed 4 teachers with 4-16 years of experience within this occupation. The method I've chosen can be described as qualitative interview with semi-structured questions to enable the teachers to thoroughly describe their answers without diverting from the original question. The questions that form this essay are: What strategies do the teachers possess to enable stability, a safe work environment and enabling knowledge-sharing for the children that are acting out? What kind of tools do the teachers use when they work with children who are acting out? The results were analysed through the theory of socialization, which simplified can be compared with upbringing.

This report describes work on the thesis ?IT systems and organizational development?. The work is carried out on Stocksbro Energi AB, during spring 2009. The company wanted better flow in their production but also review if the inventory management function located in Visma SPCS Administration 2000, could be used in the organization. Under the first part of this report the system were tested to ensure if the system would work together with the organization.

Today it becomes more and more important to work with continuous improvements to stay ahead of the competitors. Pfizer in Strängsäs started working with continuous improvements in 2010. By the end of 2012, the company?s goal is to reach 24 improvements per employee at the factory.Their project has two main purposes; to examine the need and possibilities for visualization regarding continuous improvements at the production department and to develop a concept for visualisation of the entire factory?s continuous improvements.To attain the information required to examine the needs at the production department, interviews with relevant employees at the department were conducted. Using interviews as a benchmarking instrument was also helpful in getting different points of views.

To introduce a standardized component assortment takes a lot of effort in order to make real cost savings. The rationalization effect itself is important, but perhaps even more important is to state the aim of the standardization efforts in a well-defined way. How can an organization assure that they are working in a proper way? How do they know that their efforts are being interpreted into the whole organization? And, how do they know that the standardization efforts actually save money? Different components differ heavily e.g. in technical complexity and quality issues.

This thesis has been performed at the system development company Verendus System AB, together with the home care company Basic Care Unit (BCU).The thesis has consisted of developing a web based informationsystem for BCU in which they can administrate their business. At the time of writing this thesis, BCU was using a windows-application to administrate their activities, which was both costly aswell as resulting in an unnecessary burden. The aim the thesis has thus been to create a platform-independent information system that simplifies and streamlines BCUs work by being user-friendly aswell as imposing some simplifying features.The students has been developing the system by the help of a work method they themselves developed. The method consisted of working in several iterations that each had several milestones. The method resulted in the students knowing easily when each iteration was finished or not.The thesis resulted in a working platform independent prototype.

Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.

The goal of this Bachelor project was to develop the Sundsvall42 website,whose name originates from the conference held in week 42 and during whichall the IT-companies in Sundsvall gather and hold a number of different lectures.The website has been designed to accommodate both speakers and partipicants.All partipicants and lecturers will receive a personalized page inwhich there are a number of functions which are available for use, including ablog for each workshop and a calendar. The program used to create this isLiferay and the operating system is Linux. The entire website is encoded usingLiferay and Java, but the website is not adapted for use with the smaller screensize of the Smartphone. However, because of the Responsive Design technology,the website is able to adapt to various devices such as the Ipad and Smartphonesand the website will be able to adapt to the screen sizes of these devices.As it has all been processed using open-source, everyone has the right to accessthe source code. It is also possible for anyone to make changes to the code ifsuch changes are required.

Dysfunction of the upper respiratory tract is a common cause of impaired performance and intolerance to exercise in racehorses and include several upper airway obstructions. The ones termed dynamic obstructions are primarily seen during physical exertion and affected horses often appear to be normal during endoscope examination at rest. The correlation between diagnoses made at rest respectively exercise is low, suggesting that an examination at rest alone is likely to be insufficient. The upper respiratory tract is exposed to great differences in pressure throughout the respiratory cycle; variations that are further altered during strenuous exercise and affect the rigidity of upper airway structures. In presence of great fluctuations in pressure, stability is achieved through coordinated and synchronous neuromuscular mechanisms. Due to nerve damage or anatomical abnormalities, these functions may be disrupted and further cause a dynamic collapse of the upper respiratory tract when pressure changes become too severe. The etiology behind the neuromuscular dysfunction is not yet fully understood.
