Pig behaviour during crowding : a study in organic and conventional herds

Rearing in organic pig production differs from conventional rearing; pigs have outdoor access and larger space allowances. Regardless of production system all pigs are transported before slaughter and during transport pigs are crowded together in a new environment and in a space smaller than they are used to. As pigs in organic herds are reared at even larger space allowances than conventional pigs, such crowding could possibly have a stronger impact on pig behaviour and well-being. Six pig producing herds, three conventional and three organic, were visited and pigs from each herd were enclosed during 12 minutes in a test area corresponding to the crowding on a transport vehicle. During the crowding, pigs? behaviour was observed, before and after enclosure in the test area skin lesion scores were recorded, and also measures of heart girth (for weight estimation) was done.

Hjärtsviktssjuka personers behov av psykosocialt stöd i hemmet

Hjärtsvikt är en av Sveriges största folksjukdomar och en vanlig orsak till sjukhusvistelse. Kvalificerad professionell vård i hemmet kan minska antalet inneliggande vårddygn för den hjärtsviktssjuke. Lyfts inte hjärtsviktssjuka personers behov av stödjande insatser fram finnsrisk för att professionella vårdare i hemmet inte uppmärksammar den sjukes behov av psykosocialt stöd. Syftet med litteraturstudien var att beskriva behovet av psykosocialt stöd för den hjärtsviktssjuke personen som vårdas i hemmet. Systematisk litteraturstudie valdes där 19 artiklar analyserades genom kvalitativ innehållsanalys.

Produktivitet och lönsamhet vid skogsbränsleuttag längs skogsbilvägar :

With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.

Ut ur Östersjön genom vassen : beskrivning av övergödningsproblematiken samt optimering av en reningsmetod genom skörd av vattenväxter

This study is based on AgroSeas business idea from environmental problems to valuable resource, with the objective to optimize a method to purify the already eutrophicated Baltic Sea by harvesting water plants, mainly reed. The nutrients will then be recirculated to arable land through residues from biogas production. The amount of nutrients that can be removed by harvesting the biomass depends on the amounts of biomass and the nutrient content of it, which in turn is strongly dependent on the nutrient concentration of the surrounding water. Vegetation suggested in the study for an effective nutrient uptake is helophytes: reed, cattails, reed canary grass, reed sweet grass in shallower water and lemnoideaes: duckweed and nymphaeids in the deeper parts. Competitive species has high purification ability but requires regular maintenance to avoid channeling and overgrowth. Regarding time and method of harvest, effectiveness may be improved by: harvesting plants above the water level and after flowering, a border is kept, harvesting twice a season, a bigger machine and a regular maintenance. This literature has illuminated a major environmental problem and it has been suggested optimizations for a method for cleaning the Baltic Sea through harvesting water plants, but to get a definite answer for the optimal method for each site tests should be carried out, this because many factors determine to what is suitable for each, specific environment. .

BAKGRUND: Omvårdnad skall bedrivas holistiskt enligt International code of etics (ICN) trots detta bedrivs den till viss del naturvetenskapligt med fokus på den medicinska delen, som i sig är viktig. Tydliga riktlinjer för andlig omvårdnad saknas och forskningen är begränsad. SYFTE: Syftet med denna studie var att utifrån aktuell omvårdnadsforskning beskriva faktorer som påverkar sjuksköterskors bemötande av frågor med existentiellt innehåll. METOD: Systematiskt litteraturstudie där sju artiklar och en avhandling ingick vilka var etiskt granskade. RESULTAT: Fyra kategorier identifierades, adekvat kompetens, tillåtande vårdmiljö, holistisk människosyn och reduktionistisk människosyn.

Uppvärmningssystem : Ekonomi, miljö och drift

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

Flerskiktat papper : en sammanställning av historia, teknik och forskningsresultat

Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.

Human Resource: involvering av personal : "alla ska med"

Our surrounding world is constantly changing and to be able to keep up with the fast pace of change organizations need to be prepared to transform as well. If there is a need for an organization to undergo a change process, the people constituting the organization also need to be prepared to change their behavior. In order for the change process to turn out successful, it is of the utmost importance that all employees are given the chance to take part in the process. The challenge for leaders during a change process is, therefore, to ensure that their employees actively get involved.The purpose of this study is to apply Human Resource (HR) theories on to an organization in order to critically review how leaders in practice, can involve their employees, on the basis of a change process.The study is a qualitative case study, the empirical material has been collected at Falkenbergs Sparbank with the help of one unstructured interview with an employee at the marketing department and four semi structured interviews with the office managers.Relationship oriented leadership is beneficial to use during change since it advocates an open relationship between co-workers and exchange of information and knowledge. Relationship oriented leadership is considered to be a good leadership style if organizations wants to turn Human Resource theories in to practice.

Machinima : Ett kulturellt fält i rörelse

I mitten av 1990-talet närmare bestämt 1996 gjordes en film kallad Diary of a Camper. Filmen handlade om en person som satt och lurpassade på sina fiender i ett datorspel. Det som var speciellt med denna film var inte handlingen eller något fantastiskt kameraarbete. Nej det som var speciellt var det faktum att filmen spelades in i ett datorspel. Denna film anses vara startskottet för machinimakulturen som idag omfattar flera tusen utövare världen över.Det var personerna bakom Diary of a camper som myntade uttrycket machinima som är en sammanslagning av de engelska orden ?machine? och ?animation? alltså maskin och animation.

BESLUT OM GRUPPTRÄNING : En kvalitativ studie om hinder och möjligheter för personer med hjärtsvikt.

Bakgrund: Forskning har visat att träning förbättrar den fysiska förmågan och höjer livskvaliteten hos personer med hjärtsvikt. Trots detta är det många personer med hjärtsvikt som inte deltar i gruppträning.Syfte: Syftet med denna studie var att beskriva vilka faktorer som personer med hjärtsvikt, som inte deltar i hjärtsviktsgrupp, upplever som hinder respektive möjligheter när de ska ta beslut om att delta i gruppträning.Design: Studien var en kvalitativ studie med deskriptiv design som utfördes genom semistrukturerade intervjuer med fem informanter.Resultat och slutsats: Resultaten, som tolkades utifrån beteendeförändringsmodellen Health Action Process Approach (HAPA), av denna studie visade att informanterna upplever olika hinder för träningen som har med prioritet, otrygghet, psykisk ohälsa, transportproblem och bristande information att göra. I vissa fall väljs träningen också bort på grund av att informanterna istället tränar i hemmet. Det största hindret enligt studiens resultat var bristen på information. Framförallt har informanterna bristande kunskap om träning som en del av behandlingen vid hjärtsvikt, NYHA II-III, och de effekter som träningen ger.

Buntning av grot med lastbilsmonterad utrustning :

During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.
