Representativa testnät försvenska eldistributionsnät

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.

Extraterrestrisk och terrestrisk kromrik spinell i fanerozoiska kondenserade sediment

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.

Photovoltaic installations and land allocation under uncertainty : a real option approach

A real option model is developed to examine the crucial factors affecting the agricultural firms? decision to quit the production and rent out the land to a company building a PV power plant. The public policies in support of investments in renewable energies have created the conditions for a market regarding investments in PV installations in agricultural areas.The decision to switch offers to the agricultural firm and to society several economical, social and environmental benefits, representing sustainability. However, PV installations in agricultural areas require the allocation of a certain land area. By assigning a part of land to PV installations, thereby the area of land allocated to agricultural production decreases.

"BÄTTRE BALANS I BOENDESAMMANSÄTTNINGEN" - FÖR VEM? : En studie om boendes upplevelser av social mixing i tre bostadsområden i Köpenhamn

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.

Antipredator behavior by the red-tailed guenon, Cercopithecus ascanius

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

Magasin för lagring av vatten och växtnäring

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

Energianvändning på Volvo Lastvagnar Tuve

Volvo Trucks is the second largest manufacturer of heavy trucks, with factories in several countries and with around 21 000 employees. At the plant in Tuve, trucks have been built since 1982 and the activity mainly consists of producing side members and to assemble and packing kits of trucks. In 2005, the factory in Tuve launched the ambition to be the first carbon dioxide neutral vehicle factory in the world. This will be implemented by streamlining and investing in renewable energy. The aim of this degree thesis is to map the usage of energy within production, and also to prepare a method to measure key figures (use of energy per produced unit).

V?n eller Fiende? En Studie om Kommunalt Milj?ansvarigas Perspektiv kring Invasiva Fr?mmande V?xtarter

Invasive alien plant species have historically caused major damage to ecosystems and are considered to be amongst the greatest threats to biodiversity globally. The lurking threat of harm to well functioning ecosystems has led to the development of global and regional goals and regulations which seek to stop the spread of invasive species. The Swedish Environmental Protection Agency has proposed a list of species that are specifically harmful to the Swedish flora and fauna, which includes (amongst others) garden lupin. The management of invasive species is however largely dependent on local actions, making municipal public servants key players. This qualitative study uses interviews to investigate how municipal public servants who are responsible for managing invasive alien species view this work.

Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring

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%.

Det behornade ansiktet En transtextuell analys mellan Hjalmar Söderbergs Jahves eld och andra Moseboken

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.

Förslag till kväverening i Forsåsystemet genom våtmarksetablering

The last hundred years humans have drastically changed the amount of available nitrogen in nature. Today human activities release twice as much available nitrogen as all natural processes are doing together. We also have degraded nature´s possibilities to take care of nitrogen through the draining of wetlands and straightening of rivers. In order to regain the potential of nitrogen retention in the water systems there now requires a reshape of the landscape we live in. A planned expansion of the mining activities in Garpenberg, Dalarna, would double the content of nitrogen in the waters below the mine.

Religionsundervisning : - Genom vilka pedagogiska metoder

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.

Vegetationsutveckling och brandhistorik i Tyresta under 9000 år : en pollenanalytisk studie av en skvattramtallmyr i Tyresta nationalpark, Södermanland

Analyses of pollen and charcoal in peat cores, together with age-structure data of Pinus sylvestris from a Ledum-Pinus-mire in the Tyresta National Park (south-east Sweden) show the regional vegetation succession and fire history over the last 9000 years. Five major stages of mire development are identified: 1. Lake (c 7000-6400 cal BC); 2. Wet fen (c 6400-6000 cal BC); 3. Deciduous fen (c 6000 cal BC to c cal AD 700); 4.

Analys ac konstruktionsprocessen inom FTC

This thesis work was made to optimize the writing of the construction specificationsat FKA. These construction specifications are created before each plant modificationsthat is started because requirements from the Swedish radiation safety authority(SSM) and internally on Forsmarks nuclear group as constructions / implementationdocumentationThe study was done through seven interviews of two people at three different groupsinvolved in the construction specification and an interview from the group accreditedverification. The four selected groups were selected through an extensive analyticalwork resulted in an elimination matrix where these four groups was considered to bemost involved with the construction specification.The questions asked to these individuals were based on the instructions and sampletext that are described in the construction specification. To ensure the quality of thethesis were to limit itself to the chapters that were considered most relevant toimprove. The analysis revealed a number of points that should be improved, partlyinto the routines when writing the construction specification and when ether sampletext or suggestions should be changed and complemented.

Good girls go to heaven, bad girls go everywhere- a qualitative thesis about the organization Empower and their sex working women in Thailand.

This thesis examines the organization Empower and their members, who consist of sex working women in Thailand. The purpose is to explore the more liberal point of view of prostitution and how the female members perceive Empower. Furthermore the study investigates if the organization can improve the sex workers empowerment. The study also delineates how these women reflect on their professional role as a sex working woman and whether the women relate to feminine discourses. The study is implemented in Chiang Mai, Thailand during the fall of the year 2010 and is based on qualitative methods like interview, focus group, observations and text analysis.
