Jätteträd ? inventering, bevaring, skötsel samt rekrytering :
During the summer of 2007 I was employed by Högestad Christinehofs Förvaltning AB. My
main task was to make an inventory of giant trees at the estate. Högestad and Christinehof,which with their total possession of 13 000 ha of land is the biggest estate in Scania.
A giant tree is a tree with a diameter in breast height more then 1 meter. Trees of these
dimensions are registered by Swedish authorities. Landowners with a giant tree on their
property can receive a subsidy for cutting trees that are in competition with the giant tree.(Levenskog, 2007)
Giant trees are important for biodiversity in the landscape and there are important habitats for different insects, birds, bats, lichens and funguses.
Reducering av effektförbrukning i inbyggda system med Linux
Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.
Lera för livet i lek & utforskande : en studie om pedagogers syn på estetiskt arbete i förskolan
This study intends to examine teacher´s thoughts and perception of esthetic activities at preschools. I have chosen to restrict the esthetic area to the significance and function of clay to the teachers and children. On the basis of the belief that children can, and need access to a variety of ways to express themselves, we used the interviews to take part of teachers work and thoughts concerning clay, and the esthetic work. I have in this qualitative study addressed four questions: How do the teachers use clay in preschool activities? What do the teachers think about clay as a tool in the educational work at the preschool? Are the teachers working from the perception of children?s rights to express themselves in different ways and with the help of different tools? What function does clay fill for the children?I have interviewed eight teachers and taken part of both older and more recent theories around children and the creativity in esthetic contexts.
Optimization of immunoassay parameters in multiplex in the high throughput protein detection technique Proximity Extension Assay
The ability to detect protein-based biomarkers, which are linked to different diseases like colorectal cancer, is very important as a diagnostic tool. Usually complex biological samples like blood are studied which will contribute to different technical issues when performing an assay. The aim with the project is to optimize and develop the high throughput protein detection technique Proximity Extension Assay, PEA, into a 96-plex panel, in hopes of discovering an expression profile for colorectal cancer. PEA was developed by Olink Bioscience and allows specific proteins in a sample to be quantitatively transformed into nucleic acid sequences that are subsequently detected and quantified with real-time PCR. Two proximity probes containing oligonucleotide sequences bind pairwise to target protein and when brought in proximity, a DNA polymerase will extend a hybridization arm from one probe over to the second forming a double-stranded DNA sequence that can serve as a template in real-time PCR.
Ställtidsanalys vid Albin Components AB
Examensarbetet är utfört på Albin Components i Kristinehamn som med gamla anor inom motortillverkning och komponenter till motorer har specialiserat sig på transmissionskugghjul till tung fordonsindustri.Projektet har gått ut på att analysera ställtiderna på kuggcellerna 3, 6, 8, 5 och 7. Förutsättningen för att använda produktionsfilosofin Lean Production och dess bruk av små batcher är att ha korta ställtider. Ställtiden är den tid som en maskin står stilla under bland annat byte av verktyg inför körning av en ny order. Då inget produceras under ställ är det en spilltid och som all spilltid måste det reduceras till ett minimum.SMED- metoden (Single Minute Exchange of Die) är en metod för reducering av ställtid där stället delas upp i OED (Yttre ställ) och IED (Inre ställ).Analysen har till stor del kretsat kring tidsåtgången för mätning i mätrummet som är en stor del av ställtiden. Dessutom undersöktes möjligheten att minska tidsåtgången vid själva ställets utförande och kommunikationen mellan operatörerna och mätrummet.För att uppfylla målen har kvalitativa och kvantitativa undersökningar gjorts.
Enastående ensamstående? : Valet att bli solomamma med IVF-teknologi.
Sveriges Riksdag beslöt våren 2012 att även ensamstående kvinnor ska få tillgång till assisterad befruktning i Sverige. Hittills, och än så länge, har ensamstående kvinnor rest utomlands för att fertilitetsbehandlas. Syftet med denna studie har varit att undersöka hur solomammor (kvinnor som valt att skaffa barn som ensamstående) resonerat och resonerar kring sitt val, samt hur de ser på faderskapsprocessen och den kommande lagändringen. Deltagare söktes via en förenings Internetsajt, där medlemmarna alla är frivilligt ensamstående mammor. Fem solomammor berättade om sina resonemang i semistrukturerade intervjuer.
Inköpsstrategier för ökad konkurrenskraft inom dagligvarubranschen
Term: Spring term 2007Study objects: Reitan Servicehandel AB, Vi-butikerna, ICA Sverige ABPurpose: The purpose of this study is to analyse how procurement is used as a strategy to achieve better competitive strength, within the retail food industry.Theoretical: The theoretical chapter illustrates different procurement organisations, multiple and single sourcing, brand equity, consumer behaviour and involvement, Efficient Consumer Response including supply chain and category management and finally Demand Chain Management.Method: For the case studies, three food retail companies have been interviewed: Reitan Servicehandel AB, Vi-butikerna and ICA AB. To illustrate how consumer behaviour influences retail food market, several secondary consumer research studies have been analysed.Conclusions: The results indicate that the procurement organisation can achieve a better competitive strength by a centralised organisation, which make it possible to improve conditions of terms when ordering higher purchase volumes. The sourcing strategies can improve a company?s power within the supply chain. All companies within the study had a very good knowledge about consumer behaviour.
Häst- och ridsport utifrån ett kulturpolitiskt perspektiv : Om Karlstad Kommuns ekonomiska stöd till ideella föreningar inom häst- och ridsport
The purpose of this paper is to view Karlstad Municipality and their financial support to non-profit organizations within equestrian sports. Despite the varying representatives of various equestrian sports in Karlstad, there seems to be a single beneficiary within the sport when it comes to financial support from the municipality. The policies and plans concerning cultural development are directly compared to the Karlstad Municipality and its contribution to these organizations within equestrian sports. Through interviews and reports I have studied the process of financial support from the Karlstad municipality using an intersectionality theory based on Nina Lykkes guide on gender studies and feminist theory. Pierre Bourdieu?s theories on field, habitus and capital are also used as a method to enhance the understanding of equestrian sports and its role in modern Swedish society. The conclusion is that the Karlstad Municipality is, for a several of reasons, promoting non-profit organizations within equestrian sports, which are operating as riding schools.
3D-modellen som kommunikationsverktyg
If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.
Mellanchefens dilemma : En fallstudie gjord på Skattekontoret i Örebro
In large organizations one can often find middle managers at several different levels within a company. Middle managers regularly experience their positions as complicated as they have both superiors as well as subordinates? to please. We have chosen to refer to this problem as ?the middle-management dilemma?.
När världen kom till Föra : om forskningens syn på Ölands kristnande
This paper aims to give an account of, and to discuss the view-points and theories of different researchers on the christianization of Sweden, especially the province of Öland, during the early middle ages. Its purpose is to investigate how, and in what sense, their positions can be said to correspond to what we may know of the historical ?facts?. This will be possible by comparing different points of view with a study of the development in a single parish. An overall difficulty however, is the nature of the sources relating to the time in question, they are scarce or even non-existent.Part I of the paper consists of an outline of the field of research and the different theories put forward on the subject.
Glukos och leucin som potentiellt hjälpmedel i återuppbyggandet av muskelglykogen efter hårt arbete hos travhästar
The aim of the project was to study the effect of oral administration of glucose and leucin on the resynthesis of muscle glycogen after intense exercise in Standardbred trotters.
In a crossover design, 11 Standardbred trotters performed a standardized exercise test on two occasions in order to deplete muscle glycogen. The exercise test comprised a warm up period, 7 repeated bouts of exercise on an uphill 500 m slope, and a recovery period. After the exercise test horses received: 1) a solution of glucose and leucine via a nasogastric tube at 0 minutes and at 240 minutes post exercise and a single bout of glucose at 120 minutes post exercise or 2) water (placebo) at 0, 120 and 240 minutes. Blood samples for measurement of glucose and insulin concentrations were collected at rest, when the horses returned to the stables directly after exercise and throughout the 6 hour recovery phase. During the first recovery hour, samples were collected every 15 minutes and then every 30 minutes over the next 5 hours.

The problems around and the planning of wood flow is some of the most complex issues in the forest-sector. The experience and overview of the single employees is crucial for the possibility of correct tactical and economical decision-making. The increasing demand of savings and shorter reaction-times with greater flexibility in the wood-supply-chain, makes solutions and aids for improved effectiveness in the work and processes according to wood-flow urgent.
Holmen Skog is starting to develop a new forest-road-management-system. The system will facilitate the work according to construction, improvements and updating the standard of roads.
I nöd och lust, tills döden skiljer oss åt : Sexualitet hos ensamstående män och kvinnor inom palliativ vård
I föreliggande studie undersöktes samtal där tre personer som stammar deltog i interaktioner med olika deltagarstrukturer; med en annan person som stammar, med en närstående person samt med en person i en institutionell kontext. Studien syftade till att analysera likheter och skillnader mellan samtal med olika deltagarstrukturer, med avseende på fenomenen samkonstruktion, blickkontakt vid samkonstruktion och uppbackning. Sammanlagt medverkade tolv personer, i totalt nio dyader. De nio samtalen, som var mellan 35 och 55 minuter långa, spelades in och analyserades enligt principer från Conversation Analysis (CA). Även beräkningar utfördes på fenomenen verbala uppbackningar, samkonstruktion och blickkontakt vid samkonstruktion.
Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp
At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.
