Prevalence of selected infectious diseases in Samoan dogs

SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational. The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and Maintenance of a large number of forest roads.

Kraven på ägare till minireningsverk skiljer sig åt mellan olika kommuner

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

Jämförelse mellan bullerreducerande beläggning och bullerskärm. : Ur ett kostnads- och tekniskt perspektiv.

Den bullerreducerande beläggnigen har en porös struktur som förbättrar dräneringen och reducerar buller vid källan men egenskaperna orsakar ett snabbt slitage och portäppning. Detta medför att beläggningen måste omläggas och rengöras oftare än en konventionell beläggning som t.ex. ABS 16. Kritiken mot den bullerreducerande beläggningen riktar sig på de höga drift- och underhållskostnaderna, detta gör att många väghållaren satsar på bullerskärm som bulleråtgärd.  Syftet med arbetet är att jämföra bullerreducerande beläggning med bullerskärm, för att reda på vilken bulleråtgärd är mer kostnadseffektivt under 20 år. Ett teoriavsnitt kommer att förklara och beskriva på ett tekniskt sätt: väg, ljud och buller, bullerskärm och bullerreducerande beläggningar.Kostnadsjämförelsen mellan bulleråtgärderna omfattar investering, drift och underhåll.

Presentation av underhållsföreskrifter med modellbaserat konstruktionsunderlag

Detta examensarbete utfördes på Saab AB, Support & Service, i Tannefors, Linköping, samt vid Institutionen för datavetenskap på Linköpings universitet. Ett moment i kvalitetsarbetet för komplexa industriprodukter, som till exempel flygplan, är att skifta från tvådimensionellt konstruktionsunderlag till tredimensionellt. Tredimensionella modeller har funnits i flera år. Nackdelen med dessa modeller är att de inte kunnat bära någon extra information, förutom den information som krävs för att de ska vara uppritade. Tekniken har gått framåt och nu går det att lagra teknikinformation i modellerna samt göra simuleringar som inte gått att göra förut.

Perenner i offentlig miljö : en samling exempel och erfarenheter

Abstract:Perennials in public areas have during the latest decades been more and more popular. This group of plants has become a more accepted komponent when creating pleasant public places, and people begin to see the functional aspects. Perennials do also give a colour- and senceexperience in a more detailed way than can be achieved with only trees and shrubs. One of the ojects of this essay is to give more examples of motives for using perennials in urban areas.Having in mind the increasing use of perennials, you can expect a growing need for better understading of how to create successfull perennial plantings. In spite of the increasing interest it is hard to find any written information in this subject.

Obesa personers upplevelser och hantering av viktnedgång: En litteraturstudie

Övervikt och fetma beror till stor del på ändrade levnadsvanor och är ett problem att ta på största allvar eftersom fetma kan leda till allvarliga följdsjukdomar och sänkt livskvalitet. Preventiva åtgärder är nödvändiga för att hindra den fortsatta fetmaepidemin och här kan sjuksköterskan fylla en viktig funktion som stödjare och rådgivare för obesa personer. Syftet är att beskriva vuxna obesa personers upplevelser och hantering av viktnedgång. Metoden som använts är litteraturbaserade studier av åtta kvalitativa artiklar. De obesa personernas upplevelser framkommer i tre teman. Upplevelser innan viktnedgång beskriver olika stadier som obesa personer genomgår innan de beslutar sig för viktnedgång samt beskriver även upplevelser av fördömande attityder.

HAVS ombord - en studie av hand- och armvibrationssyndrom och dess förebyggande åtgärder

On board ships different type of Maintenance activities take place. Some of those require working with vibrating handheld tools. Traditionally there is a high awareness of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards available compared to the information concerning other hazards on board.There are threshold values that workers, by law, are not allowed to exceed when working with handheld vibrating tools. The purpose of this study is to investigate how common the use of this type of equipment that can cause damage by vibrations, to the hands and arm amongst the deck crew, and if the crew informed about the risks involved.

Utveckling av nytt koncept för positioneringsslid

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.

Torrfoder till katt : påverkan och konsekvenser

The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.

Styrningens vindlingar: substitutionsbehandlingens premisser

For over 40 years, there's been a debate in Sweden of whether it's good or bad with Maintenance therapy for heroin addicts. This method is far more acknowledged in other parts of Europe and in USA. The aim of this paper was to explore how public actors manifest their thoughts concerning the subject of the substitution program in Sweden. This approach includes the complex of problems that can be found in statements and the discourses that these operators stand for and support. In my analysis the philosophical thread was principally based on Michael Foucault ideas, but also on other theories related to social constructionism.

Statusbedömning och förbättringsförslag för startkedjemaskineri, startkedja och linspel för stränggjutningsmaskin

The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive logs.
