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.

My intention with this study is to evaluate, as a singer and a voice teacher, a number of routines for daily vocal practice through practical application. Seven different routines are presented, five of them originating from interviews with Swedish vocal teachers and singers and two chosen from literature. These routines are then tried out and evaluated. Using the results of these evaluations as a basis, I make an attempt at formulating my own personal practice routine, optimal for my own needs. I will also try to address motivational issues related to practice with hints acquired through the interviews.

This thesis deals with information practices of first time parents. The term information practice covers topics ranging from the information a parent need and use, the information they actively seek for through to information attained through browsing, monitoring or simply being aware. Four problem areas have been formulated. What information do first time parents need? How do they get hold of information and how do they use it? What factors decide what sources they use? How do the first time parents validate the information they get? The following theoretical framework have been used; Marcia J Bates? model of information practice and Reijo Savolainen?s Mastery of Life theory.

Detta examensarbete har gjorts på uppdrag av SP Maskiner AB och berör längdmätningsenheten på skördaraggregatet SP451LF. Pulsgivaren i den befintliga längdmätningen anses inte nå en acceptabel livslängd och därför skall ett sensorlager prövas som ersättare.Uppdraget består i att söka ett lämpligt sensorlager, dimensionera en komplett mäthjulslagring samt att ta fram ett konstruktionsförslag till prototyp på längdmätning.Arbetet begränsas av att den omkonstruerade längdmätningen skall passa på SP451LF aggregatet. Det betyder att längdmätningens infästning mot aggregatet inte får förändras och dess yttermått måste hållas inom de gränser som aggregatets chassi tillåter..

This masters thesis aims to investigate how upper secondary school pupils experience their information seeking in a school context without access to a school library. It is the pupils own thoughts and opinions about information seeking and criticism of the sources that is the main focus. The literature that has been used consists of material from research concerning youth and different aspects of information seeking such as the information seeking process, information seeking on the web, criticism of the sources and how pupils interact with other people in order to acquire information. The method that has been used is group interviews. Twelve pupils from an independent school without access to a school library have been interviewed in groups of three.

The aim of this thesis is to examine how high school students use their school library for their information-seeking. The theoretical framework is based on Louise Limbergs three categories of students views on information-seeking and Andrew Large and Jamshid Beheshtis three categories of students choice of information systems. Qualitative interviews were used and seven high school students were interviewed. The empirical material was compared and divided into 9 categories. The results show that the students see the school library as a place where they can search for information, but its also considered to be a good place to hang out between lessons to study or to meet friends.

Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.

The aim of this literature review was to describe how the literature presents parents? need for information and how parents perceive the information from care personnel when their child 0-18 years of age is diagnosed with diabetes. The literature search was performed in the databases PubMed and Cinahl. Thirteen articles that met the inclusion criteria were studied. The results showed that when a child is diagnosed with diabetes the whole family faces a new situation and the parents are in great need for adequate information from care personnel to be able to deal with the new life situation and participate in the care.

This thesis deals with the information needs and information provision of teachers in compulsory school, from a role theoretical perspective. The object is to investigate teachers opinions on their information needs and information provision. The following questions have been used to approach the problem: Which are the information needs of teachers in compulsory school? How do teachers get the information they need? Which difficulties and deficiencies do teachers experience in their information provision, and what does the ideal situation look like? The theoretical frame of reference consists of a model of the information seeking of professionals, which is based on role theory. Qualitative interviews have been carried out with nine teachers.

Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

An information audit identifies, among other things, organizations information resources, the information flow and the needs of the information users. The purpose of this masters thesis was to describe the management of information within a local unit of Borås municipality by putting an information audit-method in practice. The focus was on three issues: What information needs could be seen in the organization? How does the information flow through the organization? How does Sugan Henczels seven-stage model serve as a tool to map the management of information within the local unit? The study only described the situation at a certain time at the chosen organization. The seven-stage information audit model was revised and adjusted to the studied organization by only carrying out four of the seven steps: Planning, Data collection, Data analysis and Data evaluation.

The main purpose of this thesis is to contribute to the understanding of information needs of eight vocational studies teachers at the Handicraft Programme at a senior high school. I have analyzed the teachers? needs of information and the empirical material has been collected through interviews with eight vocational studies teachers. To analyze the interviews I have used Lars Höglund and Olle Persson?s model for information needs and a model for information sources.

In this report, the risk of cracking in joints and/in adjacent concrete is estimated by checking shear forces in joints and the ratio between the actual maximum principal stress ant the actual strength of the concrete. The shear force has been estimated both by simple methods as well as by two-dimensional calculations. The risk of cracking in the concrete and/or in the joints is estimated with the computer program ConStre. The restraint from a resilient foundation or rock on a young concrete construction is estimated by a simple method that is exemplified. It is shown that the restraint can be neglected in some cases.

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU. The work was an assignment from Jarlträ AB which is a privately owned sawmill located in southern Småland. The aim of the work was to investigate the economical result of different pricelists and how to adjust different parameters such as length correction to give an optimal result. The pricelists was examined through a computer program (SilviA). The pricelists was made in the program and after that a simulation was preformed with a selection of random sampled trees gathered from the area nearby the sawmill.
