Spill från rundbalspress med och utan knivar :

When harvesteing ley there is always mechanical losses from the harvest machines. During the last years the roundbalers with knives,cutting the material-are more common, This use increase the mechanical losses of material. MATERIALS AND METHODS The roundbaler which used in this test was a Krone Vario Pack 1500 Multi Cut. This roundbaler has 17 knives. The theoretical length of cut was 64 mm. During the test we stretched a rubber tarp under the balechamber and collected the materials which fell down from the balechamber.

Så funkar avdelning C: en kvalitativ undersökning av användbarheten av SAB-systemets religionsavdelning i dagens svenska samhälle

The purpose of this thesis was to find out whether the main class C (religion) in the Swedish classification system Klassifikationssystem för svenska bibliotek is well adapted to classify materials published in or imported to Sweden, and handled by Swedish libraries today. The questions we put to ourselves were:1. How easy to understand, and how useful is the main class C religion today?2. What, in the main class C, is satisfactory?3. What, in the main class C, is inconsistent, anachronistic or incorrect?4. What, in the main class C, is in need of change or renewal?The method that was used was a number of interviews with librarians and cataloguers. We have interviewed eight librarians from six different libraries, of different types, but all with a relatively large collection of religious materials.Though all of our respondents have expressed a feeling that all the major religions deserve equal treatment in the classification system and a similar division of space, after some pondering on the subject, our respondents have agreed that a larger space for Christianity is warranted considering the composition of the current collections and publication. Our respondents have in some cases expressed that there is a lack of instructions as to how the subdivisions of the main class C (religion) is meant to be used.

Barns rättigheter I skola och frivillighetsorganisationer : En jämförande studie mellan Sverige och Östafrika

My purpose in this paper is to study teachers' work in reading and writing in primary school and special school. I want to find out if they use the same methods, strategies and materials to help students learn to read and write. I will find out the answer to my purpose by performing two qualitative observation and two qualitative interviews. Lundberg (2010) is the researcher I relate to during my study. Through observation, I see how teachers work with students in the classroom during a lesson in the Swedish language. During the interviews, I received answers to how teachers work with language, the materials, methods and strategies they use. I found out that teachers use specific strategies when they help their students. They use a work material that is tailored to curriculum in Swedish language and it is based on the phonics method. .

Levande material. En utforskande exposé över vårt förhållande till kroppen som organisk materia

In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.

Matematiksvårigheter : En studie om fyra pedagogers erfarenheter kring matematiksvårigheter med exempel på pedagogiskt arbetssätt

For many years, I have tried to understand why students end up in difficulties in mathematics. As a future teacher, it is extremely important to have knowledge of the various factors that leads to difficulties in mathematics. As a teacher it is obvious to meet the students who find mathematics a difficult subject, and, therefore it is necessary to have a broader knowledge of how to respond and support these students. According to Ahlberg, number of students with mathematics difficulties is increasing every year, therefore, it is important to help students and organize a supporting school environment that promotes and encourages learning (Ahlberg 2001, p. 104-105).

Flockning och förtjockning i High-Rate-förtjockare ? en jämförelse med konventionell förtjockarteknik och lamellsedimentering.

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

Analys av tidsåtgång vid montering av aggregat på Haldex Barnes Hydraules

Haldex Barnes Hydraulics (HBH) is a company which produces hydraulic aggregates for use in forklifts, construction equipment, and trucks. The last two years the company has expanded. This has lead to an insufficient production of aggregates. Thus wishes HBH to increase their production without making to large investments.This report includes a now-state analysis of the problems and where they are. From this a further analysis of possible improvements are made.HBH works mainly with assembling and this is made manually.

SANNINGENS ÖGONBLICK En komparativ undersökning av ett stadsbiblioteks och en byggvaruhandels arbete med att möta sina besökare

The purpose of this thesis is to discuss how a Swedish public library approaches their costumers. I will show how a library interacts with their costumers compared to a business, which has a different economic work frame, a building materials supplier. My aim is to pinpoint differences and explore new methods for the library in order to improve their service.The theoretical frame of the thesis is based on Richard Norman's notion the Moment of truth. The moment of truth is the moment when a business has to convince their customer that they offer both the product, proficiency and service that the customer needs. Service encounters at two organizations have been observed and their differences and similarities compared.

Egyptens balsameringsteknik : en kemisk analys av organiska lämningar

This paper deals with the embalming process in ancient Egypt. Samples were collected from six objects from Medelhavsmuseet in Stockholm. The objects were one supposed ladle and five different contents from pottery. Fourier transform infrared spectrometry (FTIR) and gas- chromatography/mass spectrometry was used to characterize the components of the materials. The result was then correlated with previously made analysis of embalming materials to discover similarities.

Utvärdering av den nationella söktjänsten LIBRIS

LIBRIS is a national library search engine offering information about 6 million books, articles, dissertations and other materials held by Swedish university libraries, research libraries and public libraries. In December 2007 a new version of LIBRIS was launched, developed with focus on usability, simplicity and accessibility. This thesis examines how the new LIBRIS is used, what is working well and what could be improved and also what the users think of LIBRIS. The following report is based partly on a study of usability and partly on a series of tests where librarians, scientists, students and developers have executed a number of tasks while thinking aloud. The users also participated in an interview.

Exercise pens as an environmental enrichment for laboratory rabbits

This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.

Effektivisera materialflödet med hjälp av självgående truckar

The thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers..

Konsolidering av v?vsp?nda papperstapeter: analys och metodutveckling

Printed and painted wallpaper on a weaved fabric backing was a common way to decorate homes in Sweden during the eighteenth and nineteenth centuries. Not much is written about the craftsmanship in relation to the hanging of these wallpapers and even less about the conservation of the objects. Even so, many wall segments remain in situ and in museums and are more often than not in dire need of conservation such as deacidification and consolidation. These are composite objects, consisting of cellulose materials with different properties along with adhesives and paints. Analysis of the materials is required to ensure safe handling and choice of conservation materials, and to establish a treatment plan which will be executed in several steps. This thesis aims to identify these steps and develop a method for conserving the wall segments with suitable materials, preferably without altering the source material to any significant degree.

Religionslärares användning av tidningsartiklar : en kvalitativ undersökning om alternativa läromedel

This study discusses and examines the alternative teaching materials in religion class amongst seven teachers in Stockholm region. As religion is a complex subject to both learn and to teach it may be beneficial to use alternative texts to show the diversity of the subject. The aim of this study was to examine why teachers use news articles and other articles from daily magazines in their religion class. I also examined how the teachers motivated their choices of teaching materials. The study is qualitative and the empirical work was done by interviewing seven teachers in religion.
