Införande av mjuka golv för mjölkkor : en fallstudie

Soft rubber flooring have gained in popularity over the last years. Rubber flooring al-lows cow to move more freely without slipping and improves claw and leg health. The purpose of this study was to investigate the influence of a stepwise introduktion of soft flooring on cow`s placement in cow houses with robotic milking. A case study was carried out in a herd in northern Sweden with 41 cows. Observations were made every 15 minutes between 09.00 and 16.00 concering cow placement in cu-bicles, in cubicle alley, in feeding alley and in feeding alley with the head through feed-ing gate. One observation period was carried out per flooring alternativ: 1) all concrete slatted floor, 2) rubber slatted floor in feeding alley and concrete slatted floor in cubicle alley and 3) rubber slatted floors in feeding alley and solid rubber floors in cubicle alley. The study showed that 6 %-units fewer cows lay in the cubicles when the feeding alley surface was slatted rubber.

IKT i den nya lärarutbildningen : En kritisk granskning av det fjärde perspektivet

The aim of this paper is to investigate how well information and communication technology (ICT) is implemented in the new teacher training program in the subject of Swedish and how this is presented in the applications for examination licence to the National Swedish Agency for Higher Education. This is an interesting field of study, since ICT has been selected, by an investigation chosen by the government to be one of four overall perspectives that are supposed to permeate the teacher training program. There have been several difficulties involved in this project of which one has been the extent of the material.  27 applications and all curriculums in the subject of Swedish belonging to them have been examined. Another difficulty was that the applications and the curriculums are written by different persons under different conditions such as time and resources.

Bedömningsgrunder för avsyning av textila material

Dagligen bedömer människan sin omgivning utifrån sina fem sinnen. Då ett intryck ges från omgivningen sker en process, signaler skickas till hjärnan via nerver ifrån det sinne som stimulerats. På grund av den olika uppsättningen nervceller upplevs samma intryck skilt bland människor. I textilproduktion används visuell bedömning genom hela produktionsprocessen, från garn till färdig vara där tyget slutligen kontrolleras i sin helhet vid avsyningen. Avsyningsprocessen sker vid ett avsyningsbord där en operatör matar fram tyg på bordet.

The aim of this thesis is to assess landslide susceptibility in Huddinge Municipality in middle Sweden. The main purpose is to produce a map, to visualize landslide susceptible areas, and to integrate the result with changes in physical factors such as climate change. Also, the thesis aims to analyze anthropogenic factors such as changes in land use and an increasing population in Huddinge Municipality. Methods used are GIS-analyses, interviews with staff of Huddinge Municipality, and field observations.

Lönsamhetskalkyl för produktion av gran på markavvattnad och askgödslad myrmark

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.

Parametriserad 3D-modell av cyklon : Parametrisering av en 3D-modell av ett cyklonfilter i SolidWorks för snabb framtagning av nya konstruktioner till Outotec Skellefteå

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

Är medieelevens datorkunskaper likvärdiga medielärarens? : En självskattning från lärarens och elevens perspektiv

The aim of this essay is to get knowledge and to evaluate if the media student has equal or evenbetter knowledge of information technology (IT) than his/her teacher. Today the student of IToften has knowledge of hard ware and soft ware sometimes even unknown to the teacher. Themain reason for this might be that IT hitherto has played no prominent part at the institutes ofteacher education. Continuing further education of IT for teachers is also eligible as IT still is arather new subject on the time table.To adopt an empiric approach to the problem I have used trough interviewing and questions bothteachers and students at two upper secondary schools in the province of Värmland. The schoolsare called ?A? and ?B? in my investigation.Does the teacher have enough knowledge to give the student relevant knowledge concerninghard ware as well as soft ware to handle the computer and to utilize its possibilities? How can theteacher act to comply with the students? claims and demands?IT-knowledge can be expressed in a complicated way but I have limited my investigation to therole of the teacher and how he/she manages to teach and instruct concerning a selected numberof soft ware and how the students evaluate their own knowledge compared to that of the teacher.My investigation shows that the teachers consider their knowledge relevant for their task asinstructors and teachers.

Utveckling av nytt koncept till processmaskin

Metso Paper offers a front-running range of solutions and services for the pulp and paper industry. At the baling unit, design solutions are developed for manufacturing and handling of pulp bales. The machines are continuously developed to satisfy customer needs. One big step in the development of the baling line was to remove hydraulics from the machines and replace it with electrical motors and pneumatics. This was not done on the folding machine which is still driven by mainly hydraulics.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Breakfast and cognition from a youth perspectiveAuthor: Linn Kruse and Anneli HulldinSupervisor: Anna WinkvistExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 26, 2014Background: Breakfast as an influencing factor on cognition and is often on the table for discussion in society. A lot of research has been done about how omitting breakfast affects adolescents and their short time cognition. Cognition is complex as a concept and is measured in different ways and the existing research in the area often compares different types of breakfasts instead of the difference between eating and omitting breakfast.Objective: To evaluate the scientific evidence for an association between adolescents? breakfast eating and short time effects on cognition in adolescents.Search strategy: To find relevant articles a systematic literature search was made in the databases PubMed, Scopus and Cochrane. Search terms that were used were: children, young adults, adolescents, cognition, and breakfastSelection criteria: Ages 12-20 years, measures cognition, RCT, studies comparing breakfast eating with omitting breakfast, human studies, language English or Swedish, no sick adolescents or adolescents with diagnosis.Data collection and analysis: Two original articles met the inclusion criteria and were reviewed by the SBU audit template for RCT studies.

Lyfta Lätt Tekniskt hjälpmedel för pakethantering

People working with handling parcels in terminals are often victims of musculoskeletal injuries. This is largely due to the hazardous lifting of too many parcels which are too heavy and unsuitable work postures. The human body?s ability to lift and grasp objects is so outstanding that developing a device with the same capability is very difficult.The goal of the project has been to develop a technical device that will improve the handling of parcels with regard to ergonomics. The area of concern was the lifting of parcels between the conveyor belt and the cargo space of the freight car.

Balkanisering och klassifikation : En komparativ studie av klassifikationen av forna Jugoslavien, beträffande språk, geografi och historia, i DDC och SAB

This master's thesis examines the possibilities of correction and change in a classification scheme, with regard to the changes that occur in the world the classification system intends to describe.Applying a comparative method and classification theory, the classification of the example of the former Yugoslavia (1918-1941, 1945-1991), its republics and successor states, and the languages, formerly known as Serbo-Croatian are examined through a comparison of the main classes and divisions of language, geography, and history, in Dewey Decimal Classification (DDC), and Klassifikationssystem för svenska bibliotek [Classification for Swedish Libraries] (SAB). Eight editions of DDC, from 1876 to 2014, are compared to seven editions of SAB, from 1921 to 2013. The editions have been selected in order to show the changes prior to, and following, the First World War, changes after the Second World War, and changes following the collapse of Yugoslavia in 1991.The examination shows that both systems have updated their editions according to the changes in former Yugoslavia over the years. DDC has well constructed facet schedules, especially Table 2 concerning geography, but fails, in some cases, to construct a logic and hierarchical structure for the republics and languages of Yugoslavia, partly due to the fixed classes and divisions that survive from the very first edition of DDC from 1876, but also as a result of the decimal notation, and its limitations, itself.SAB seeks to construct a hierarchically logic and equal scheme for the languages, areas, and states of the former Yugoslavia. Although the facets for geography and chronology aren't as developed as the ones in DDC, the overall result is that of a logically consistent and hierarchically clear classification, with short notation codes, thanks to the alphabetic mixed notation, which allows more subdivisions than the numerals and the pure notation of DDC.This study is a two years master's thesis in Archive, Library and Museum studies..

Styrsystem : För en forskningsutrustning

The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.
