FE safety analysis of a high speed wood planer cutter. An alternative method to achieve the requirements of EN847 standard
In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.
Effekter av högt kaliumintag på magnesiumbalansen hos mjölkkor :
Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms.
The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.
CARABAS III Konstruktion av antenninstallation på helikopter
This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.
Svensk design i MoMAs samling : en studie om samlingens samband med marknadsföringen av svensk design i USA 1930-1960
Museum of Modern Art har varit mycket tongivande för historieskrivningen och definitionen av modernismen, "the international style". Svensk modernisms mest kärnfulla period 1930-1960, representeras av 55 objekt i MoMAs arkitektur och designsamling. De svenska objekten i samlingen visar på en reception av svensk design som mest inflytelserik under 1950-talet. Årtiondet är det mest välrepresenterade, till antalet objekt räknade, men ger också den mest representativa bilden av hur svensk design marknadsfördes i USA.De mest inflytelserika tillfällena för marknadsföringen av svensk design i USA under åren 1930-1960 är enligt konstprofessor Jeff Werner (Medelvägens estetik: Sverigebilder i USA), världsutställningen i Chicago 1933, världsutställningen i New York 1939 och utställningen Design in Scandinavia 1954-1957. Knappt hälften av de representerade formgivarna i MoMAs samling fanns med under marknadsföringen ,vilket kan visa på samband mellan marknadsföringen och samlingens karaktär..
En snygg fasad är inte allt : En studie om tillit och säkerhet inom svensk e-handel
Trust is the most important thing for a webshop. The consumers must be able to feel trust to choose to submit their personal information to a webshop. In this study we examine the impact that design has on the consumers trust and confidence. We study six consumers that are engaged in e-commerce in their everyday life. By allowing these participants to be presented with two different webshops, an assessement could be made in both how much design is affecting and also which parts of the design that leads to trust and lack of trust.
Studier av alkaliskt fosfatas och kollagen samt deras betydelse för skelettets mineralisering
There is convincing research which shows that the enzyme alkaline phosphatase (ALP) has a central role in the mineralization of bone, more precisely that its catalytic activity is needed in the process. ALP is found on the surface of matrix vesicles where the mineral is formed. One theory about the function of the enzyme is that it binds to fibrous collagen in the bone and thereby incorporating the mineral into the bone. The purpose of this study is to establish whether ALP binds to collagen. If this is the case, more elaborate studies around this will be performed.

AimThe aim of this study is to through managers in eldercares deskriptions of the systematic qualityleadingsystem examine the implementation process of this system in the eldercare in the municipality of Halmstad. BackgroundIn this paper the background explains elderly care and social work context, leadership in change and implementation processes. The theoretical frame illustrates Vedungs implementation theory and Webers model of bureaucracy MethodTo collect empirical data for this study, a qualitative research design was used in which eleven managers within Halmstads municipality home care management stood as respondents. ResultThe respondents highlighted a variety in the use of the systematic quality management system tool. The result describes that several obstacles were experienced in the use of the systematic quality system. ConclusionBased on the descriptions the respondents gives of the implementation process of the systematic quality management of Halmstad municipality home care management, the conclusion can be drawn that the implementation process has not resulted in the employees making use of systematic quality management in practice. The systematic quality management system that will ensure the quality of the care work is thus used to a limited extent..
Ägglocksmaskin : Produktutveckling på en maskin som hanterar ägglocken
The project has involved the development of two kinds of shooting targets in partnership with Marcus Bergkvist and Christopher Åkerblom. The project from the client was divided into two parts. This thesis discusses solutions for hands-on transport, development of tripods and an overall design. The second thesis affect resetting systems for the products.The work was done with a process and methodology based on design perspectives. This process has involved the search of relevant data which has provided the platform and opportunity for appropriate and purposeful design work.Concept development has been done using hand sketches and Photoshop, where a simple visualization of different concepts for the tripods has been produced.
Att gestalta utan plats : en redogörelse för en teambaserad gestaltningsprocess
The Landscape Architecture Program at SLU, Ultuna provide several design courses. Within these courses, students are mainly introduced to one type of design process, a
process based on the specific site and its conditions, known as Genius Loci. This report presents a course and a design methodology from Cornell University which aims to
provide students with tools for a more conceptual way of thinking about design and architecture. The design method is presented in two stages. First an introduction to the
course description and objectives.
Gapet mellan teori och praktik i pappersprototypande : en studie i diskrepans mellan det ideala arbetssättet akademin förespråkar och hur praktikern faktiskt arbetar
This study presents an alternate viewpoint to the strive to overcome the gap between research and practitioners within paper prototyping in interaction design. Earlier research identifies three aspects of this gap, which is:Practitioners being unaware of interaction design methods and theoriesPractitioners being aware, but choosing not to apply these methods and theories, due to time, budget and constraints of labourPractitioners and research having different perspective on similar design issuesOur study was done by carrying out qualitative interviews with interaction designers based on two digital design bureaus. One of the bureaus has an expressed link to research: the other has not. Our hypothesis is that the gap would manifest as a difference in work practice between the two bureaus.Our study shows that the two bureaus have similarities in work practice and that this work practice is based on scientific methods and theories, but is adapted to fit the client and/or the project. We conclude that the overcoming of the gap might not be necessary.
Ett ärendehanteringssystem för mobila enheter
The purpose of this project was to create a system which can handle issues, with other words an issue tracking system. The system must create issues, assign issues to a specific user and list all issues for each user. On top of that, each issue should have a log where users can log whatever they want.My part of this project was to implement a client which can fulfill this basic criteria (and a bit more if possible), and communicate with the server which has procedures to be executed by the client.This system is based on Android and has it purpose to be used by mobile devices which support Android. ?Ichnaea? as the system is called, is meant to be used by companies to have human interaction through the network..

Water constructions - as a design element in public spaces is the title of this Master thesis, with a focus on waters function and meaning in the urban environment.
By way of introduction, mans relationship to places is described and the factors that contribute to the reality that we prefer some places more than others. A good place to stay is open but well defined, gives protection, offers a good view and is varying in topography and vegetation, together with contents of single landscape elements like visible water.
This study then continues to discuss mans relationship to water and its means for our wellbeing. Despite the fact that people have a different relations to water due to personality, background and age, it?s an element that raises positive feelings, interest and aesthetic pleasure for most people.
Mindfulnessbaserad Rökavvänjning i Grupp: en explorativ studie
The aim of this study was to develop, implement and evaluate a mindfulness- and acceptance-based smoking cessation program in group (MRG). MRG was developed into an intervention consisting of 6 group sessions during 35 days including individual homework assignments. 8 of 10 participants completed the program. In order to evaluate the effect of MRG a quasi-experimental design with pretest and double posttest (second posttest at 1 month) was chosen. At second posttest, 50 percent (of 8 completers) were non-smokers, and the rest showed a decrease in smoking at a rate between 45 and 75 percent.

Lärares syn på hur den fysiska klassrumsmiljön påverkar elevernas lärande
My main purpose for this paper was to find out what the four teachers I interviewed thought about the design of their classroom and how they linked that to pedagogy, pupils learning and policy documents. I also wanted to find out if classroom design were something they discuss and reflects on in the college.My questions for this study were: What do some teachers who work in the early ages in the school think about the classroom design? Do these teachers link the classroom design to policy documents or pedagogy? Do these teachers consider classroom design to be something that should be discussed in the same way as other factors (for example teaching aids, resources etc.) within the college?My method was to make qualitative interviews with four teachers, analyze their answers and link them to my main theories and research in the area of the study. My main theories were multimodal communication, which means that there are several systems of signs in communication, which all have an essential function for the meaning of the communicated. It also means that learning happens both individually and socially and that school is a social construction, and that the system of opportunities and boundaries in which it takes form is mediated within our multimodal systems.
