The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

Background: Cerebral Palsy is usually divided into three subgroups: ataxic, spastic and dyskinetic, where children and adolescents can, because of misestimation in nutrition and energy intake, suffer from weight problems.Aim: To compare calculations with equations with the individual's measured RMR in the subgroups, to see if any equation is more suitable. This could be used as a tool to calculate the resting metabolism at times when it is not possible to perform clinical measurements.Method: The RMR has been measured in 37 children and adolescents aged 3-15 years through indirect respiratory calorimetry. Those values have been compared with calculations from five equations. The results were then analyzed in order to find if any equation is better to apply for calculating resting metabolism for each subgroup.Results: The ataxic group was overestimated by 56.5% of the calculated values. WHO/FAO/UNU?s equation indicates a significantly strong correlation between the measured and calculated values (r=0.85, p<0.05).

This study was carried out at the Swedish University of Agricultural Sciences, Dept. of Agricultural Research for Northern Sweden. The aim of the study was to determine how plant species richness and diversity influence the nitrogen pools and nitrogen fluxes in the soil. Plant and soil samples from a biodiversity experiment in grasslands were used. Thirty plots with 12 grassland plant species (legumes, grasses, and non-legume herbs), combined from 1-12 species were investigated.

The quality of meals is included in the constant improvement of each preschool. The study is carried out on behalf of the City of Malmö and Environmental Management and focuses on this quality work. By compiling a checklist of meal quality and by identifying what the meal quality means for persons working with the meal (managers, cooks, educators and parents), it is our wish that this will be a help in their quality work. To inspire the Composition various organizations working methods and ways to manage, evaluate and make use of different models and tools to improve the dining quality, has been studied. In the literature, the work has received confirmation of theories that emerged during the analysis work of what a meal is and how quality can be measured. The results show that food quality is described as a complex concept consisting of different parts, where the food, atmosphere, service, together form the meal quality. The semi-structured interviews and the inquiry form, have given an indication of the preschool work with quality in the meal activities and it shows that on a wide range and large differences.

The connection between rune stones and churches is a known phenomenon. Unfortunately, very little is known about the previous function of the church sites, and consequently very little is known about what the connection between rune stones and churches means. The purpose of this study is to examine the rune stones connected to churches in the administrative province of Jönköping, in an effort to ascertain their purpose, symbolism and function. The aim is to find out if the rune stones connected to churches were primarily or secondarily placed on the site where the church was later built, and why some rune stones were built into the churches. Further, the inscriptions and iconography of rune stones have been analysed, and also their relation to their immediate surroundings.

Flertalet studier har påvisat ett samband mellan koncentrationen av partiklar ? 10µm i luftföroreningar och cardiovaskulär- och pulmonell morbiditet och mortalitet. Vid resektion, koagulering/bränning med diatermipenna under operationer alstras rök. Denna rök innehåller bland annat mutagena och carcinogena partiklar i inhalerbar storlek (partiklar ? 10µm).Ett första syfte med denna studie var att kvantifiera den mängd ultra-fina partiklar (UFP) och partiklar ? 10µm som operationspersonal exponeras för i operationsrummet, vid användande av diatermi med mobilt rökutsug.

Under det senaste årshundradet har de svenska skogarna genomgått en omfattande förvandling, från mer eller mindre naturligt dynamiska till hårt brukade skogar bestående av monokulturer av tall eller gran. Denna förändring har lett till en minskning av den biologiska mångfalden, att många arter som är beroende av skog har minskat radikalt och hotas av utrotning. Som ett försök att främja variation, biologisk mångfald i allmänhet och förhindra minskningen av rödlistade skogsarter introducerades i början av 90-talet en viss naturvårdshänsyn i brukade skogar. I den här studien utvärderas den påverkan som kalavverkning har och den betydelse hänsynsträd har på artsammansättningen och förekomsten av ektomykorrhizasvampar (EMF) under de första 20 åren efter kalavverkning. Studien utfördes genom extrahering och identifiering av svamp-DNA från jordprover tagna på kalavverkade ytor, nära hänsynsträd och i gammal skog i ett begränsat geografiskt område i norra Sverige.

Syftet med denna studie är att ta reda på hur kompositörer inom genren svensk folkmusik idag går till väga när de komponerar ny musik, hur deras arbetsprocess ser ut och vilka arbetssätt de använder sig av. Det teoretiska perspektivet är hämtat från Stan Bennet och Max Grafs tidigare forskning om hur kompositionsprocessen ser ut för kompositörer inom konstmusikgenren. Ett didaktiskt perspektiv används också som utgångspunkt. Bakgrunden till arbetet baserar jag på tidigare forskning om kompositionsprocessen, forskning om gehörsmusik och kreativitet och idé-skapande. Jag ser även till vikten av att tränas i sitt divergenta tänkande som komponerande innebär.

The stretch from the riparian zone of a major river, through the mouth and upstream in tributaries forms a range of differing habitats. The aim of this study was to investigate the effect of these different habitats on the riparian frog community in primary rain forest in Borneo; i.e. examine whether any gradients could be demonstrated in terms of species Composition, diversity and density of frogs, as well as which environmental characteristics that seem to be of most importance in forming habitats of high conservational value. A major river, Segama, and three of its tributaries were investigated. The surveys were carried out at night by searching for frogs visually and acoustically along the streams, from the shore of the Segama river and 400 metres upstream in the tributaries.

This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power  istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

Social mixing går ut på att ?mixa? befolkning av olika klasser i ett bostadsområde med syfte att förändra områdets sociala sammansättning. Syftet med uppsatsen är att undersöka social mixing som urban utvecklingsstrategi i Köpenhamn utifrån boendes egna upplevelser av sina bostadsområden. I Danmark definieras 29 bostadsområden som ?ghetton? utifrån kriterier rörande de boendes anknytning till arbetsmarknaden, ?icke-västliga? härkomst samt kriminalitet.

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, Composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

The aim of this study was to analyze the transtextual relationship between Hjalmar Söderberg's Jahves eld (The Fire of Yahweh, 1918) and the Book of Exodus. A limitation was set to just focus on the theme regarding the horned face of Moses, which Söderberg extensively discussed in his book, both through narrative and commentary. The methodological and theoretical approach could best be described as a qualitative text analysis where Gérard Genette's model of five types of transtextual relationships (intertextuality, paratextuality, metatextuality, architextuality and hypertextuality) was used in order to systematically classify the various relationships and in a thorough way relate the texts to each other.The analysis shows that the transtextual relationships are many and varied, and some appears to be more relevant to the study than others. Due to the Composition of Jahves eld, its first part (?I österland, i fjärran tid?, most easily described as a paraphrase and pastiche of the Book of Exodus) can be identified as a hypertext to the Book of Exodus, while the second part (?Markels försvar?) is rather a metatext to both the first part and the Book of Exodus.

AbstractMy feature career as a teacher, for the early years of compulsory school, makes it interesting to finding out of how teaching religion can be donned. I am interested in what methods can be used for teaching religion That?s why my purpose aims to find out how five different teachers, of the early ages, works and what methods they use while teaching religion. My issue for this Composition is: what methods, or to a point - methods supported by different teaching models, can be used for studying religion in compulsory school? Empirical and specialized literature points in the direction fore methods like storytelling, load reading, drama, group works, independent searching of information, working books and so on.
