About a quarter of the Swedish land area is covered with shallow or thick peat. There is a potential to increase forest production in Sweden with almost 2 million m3/year in selected peatlands with low conservation values. This increase can be accomplished by drainage, complementary drainage, ditch maintenance operations and fertilization. The purpose of this study was to determine the level of knowledge regarding the management of forests on peatlands and was restricted to selected forest companies in Västerbotten County, with offices in Umeå. Three companies were chosen, SCA, Holmen and Norra Skogsägarna.

The purpose of this thesis was to make an energy survey and quantify energy flows of individual unit operations associated with the biogas production in Uppsala Vatten och Avfall AB:s biogas plant, located at Kungsängens gård. Moreover, large consumers of energy would be identified and analyzed. The objective of this energy survey was to obtain a detailed understanding of the energy use in the biogas production. The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted and multplied with the measured time of usage.

?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes. In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests. So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland. We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning. A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests. This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.

Radon is a hazardous substance that cannot be perceived by our senses. It has long been known that exposure to high radon levels for a long period of time will ultimately cause lung cancer. The Swedish Radiation Safety Authority estimates that 500 people die annually due to this. Although most of them are smokers, even non-smokers suffer from lung cancer caused by radon. The statutory value for radon in homes today is 200 Bq/m³.

Bakgrund: Akutmottagningar har generellt ett hög patientflöde alla dagar på året. Hit söker sig människor med olika slags alla möjliga fysiska och psykiska besvär för att hjälp. Med en kraftig arbetsbörda, stressig arbetsmiljö och sjuka patienter ska sjuksköterskorna lyckas skapa vårdande möten med patienterna. Detta kan ibland vara besvärligt för sjuksköterskan då många faktorer påverkar relationen med patienten. Syfte: Att beskriva sjuksköterskans upplevelser av mötet med patienter på en akutmottagning.

Hygien är en viktig del av sjukhusvård och det finns många utarbetade rutiner och föreskrifter. Då det tekniska kunnandet ökar, ges möjligheter till fler och mer avancerade kirurgiska ingrepp och när krav ställs på kostnadseffektivitet, ökar risken för vårdrelaterade infektioner. Att kunna förebygga och förhindra smittspridning på en operationsenhet är därför av största vikt. Studiens syfte var att undersöka faktorer som kan minska postoperativa infektioner inom operations-sjukvård. Metoden har varit litteraturstudier och baseras på 20 vetenskapliga artiklar.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

Att framföra ett utryckningsfordon skiljer sig från att framföra en vanlig bil bland annat för de större friheter gällande trafikregler utryckningsförarna har. Dessa inkluderar både rätten att köra i högre hastigheter än annan trafik, men även möjligheten att kräva fri väg från andra trafikanter. Detta skapar en speciell interaktion mellan trafikanterna i trafiken där utryckningsfordonet kan ses som en lagligt olaglig agent. Avsaknaden på restriktioner gör dock körningen helt beroende på de enskilda utryckningsförarnas bedömning kring körbeteende. Trots det finns det inga nationella riktlinjer i Sverige fällande utbildning av utryckningsförare.Den här studien undersökte normer och värderingar kring trafiksäkerhet hos operativ personal inom en ambulansorganisation.

Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.

Doktriner utgör väpnade styrkors viktigaste beskrivning avseende hur man avser använda militära medel för att uppnå politiska mål. För att tjäna sitt syfte bör doktriner utvecklas med rationella utgångspunkter som omvärldens utveckling och senaste forskning. Dock menar många att andra faktorer sprungna ur kulturella traditioner och organisationers särintressen påverkar tillkomsten av doktriner.Civil-militärt samarbete har i moderna konflikter blivit allt mer betydelsefullt. Strategier för fredsfrämjande insatser i dagens komplexa konflikter bygger i allt högre grad på integrerade insatser mellan flera olika funktioner och aktörer. Civil-militärt samarbete har dock traditionellt haft en underordnad, stödjande roll i militära organisationer.I denna uppsats undersöks forskningens roll i doktrinutveckling.

Bakgrund: Basala hygienrutiner ska enligt Socialstyrelsen tillämpas för att förebygga vårdrelaterade infektioner (VRI). VRI är ett hot mot patientsäkerheten och kan medföra ökat lidande för patienten och ökade kostnader för samhället.Syfte: Att undersöka följsamhet till basala hygienrutiner inom ambulanssjukvård i ett antal utvalda omvårdnadssituationer.Metod: En deskriptiv kvantitativ studie där data inhämtades genom strukturerad observation. Bekvämlighetsurval tillämpades och totalt 68 observationer gjordes på två ambulansstationer inom samma landsting.Huvudresultat: Följsamhet till basala hygienrutiner varierade, med högst följsamhet till rutinen om kort eller uppsatt hår (87%) samt till användning av handskar (87%). Lägst följsamhet observerades till rutinen om handdesinfektion före patientnära arbete eller användning av handskar (1%). Inte vid någon observation (0%) visades följsamhet till samtliga sju basala hygienrutiner som undersöktes.Slutsats: Att brister av varierande grad fanns i följsamhet till basala hygienrutiner.

Due to the obvious fact that one can never be hundred percent sure of what's hiddenunder the ground surface, construction work is naturally hard to project.However, many of the work methods are executed in the same way on variousprojects. The department of construction work at JM AB region öst describes a lackof follow-ups and feedback between the calculators and production managers.In this thesis we have studied the communication between these groups and alsohow they share experiences and knowledge. In order to get the full pictureof the day-to-day operations we used three methods to gather information. Studyingliterature gave basic knowledge of theories about feedback, and thenecessity of working with giving feedback. In order to understand the process ofconstruction work we made several interviews, both structured and nstructured.

AbstractThe aim of our study was that from a Preschool Manager?s perspective to describe, analyze and understand the function of special education and the Special Education Teacher?s profession within preschools. We conducted twelve interviews with Preschool Managers in two northern Swedish municipalities. From a theoretical base, we used both the relational and categorical perspectives. All answers from these interviews have been analyzed from these perspectives.

The aim of this study is to investigate into the use of discussions in the classroom to help the pupils develop a deeper understanding of mathematical concepts and operations. The empirical data contain interviews with two teachers and observations from their lessons. The purpose of the interviews was to find out what importance the teachers ascribed to the ability of their pupils to talk about mathematics, and how they organised their classes to encourage mathematical discussions. With the observations, I was able to see the interaction in the classroom and hear discussions between the teacher and the pupils, as well as between the pupils themselves.The interviewed teachers proved to share my own belief in the results of researchers like Malmer (1999) and Löwing (2006) about the importance of verbal discussion, argumentation and reflection during mathematics classes. But convictions derived from the research of others are one thing, the practical application of the wisdom in the classroom another.
