Fairtrade i Karlstad : En undersökning om utbudets utveckling och karlstadsbornas upplevelse av märkningen
It takes a very long time for ionizing radiation of used nuclear fuel toreturn to a natural background level, for this reason one of the requirements for theselection of the location of a repository was that the environment as well people'shealth would be protected from the harmful effect of radioactivity. This requirementmeans that the waste must be isolated in a geological formation. In Sweden therepository will be built in the crystalline bedrock. The location for the Swedish nuclearfuel repository at nearly 500 meters depth at Forsmark in Östhammar was decided 3June 2009. The repository will be located at Söderviken, close to the Forsmarknuclear power plant in a 1.90 billion year old bedrock that will accommodate 12,000tons of spent nuclear fuel.
Effekt av sönderdelningsgrad och planteringsdjup på uppkomsten från rhizom av Tussilago farfara :
Tussilago farfara, coltsfoot, is a troublesome perennial weed with deep lying rhizome, which can vegetatively generate new plants. The mechanical control of coltsfoot that is used today, "starvation", which consists of several cultivations of the soil, which fragmentises the rhizome. This results in production of new shoots, which leads to depletion of nutrient resources; as long the new plant is not allowed to establish. However, very little research has been done to investigate how the starving technique affects the regenerative ability of coltsfoot. The purpose of this experiment with coltsfoot was to investigate how fragmentation and burial depths affect the time of emergence, number of emerged shoots per rhizome fragment, number of shoots per node, and if the germination ability within nodes changes during the experiment.
Internet som politiskt medel : Hur Web 2.0 kan användas för att bryta trenden av politisk desillusion
Political disenchantment and detachment is proven to be growing in well established democracies. This development brings along concerning behavior regarding general political participation. Fewer citizens participate in elections, parties are losing members, and the trust in politicians is steadily decreasing. IDEA (Institute for Democracy and Electoral Assistance) has been registering voter turnout worldwide for the last 60 years and their publications show a decline in voter participation since the 1980s.During the same period of time another development has caught attention, namely the fast progress of the medium Internet. The new generation of Internet functions is called Web 2.0 and allows users not only to create content, but also to interact with each other.This dissertation aims to explore the possibilities emerging when integrating Web 2.0 in political processes.
Hur bemöts barn i det virtuella biblioteksrummet? : En socialsemiotisk bildanalys av fyra folkbibliotekswebbsidor.
The purpose of this master's thesis is to examine how the public library communicates with young users through the library web sites. Four Swedish public library web pages for children are analysed. In the analysis the web pages are treated as a combination of semiotic resources that, communicating as a whole, hold a meaning potential. In order to identify the underlying meaning of the whole I have applied the tools of Kress' & van Leeuwen's visual social semiotics to the chosen web pages.The information value, the framing and the salience of each composition is examined and analysed, as is the size of frame, the perspective and the vertical angle of a selection of images from each web page. The results of the semiotic analysis are then discussed and related to Jochumsen et al:s four space-model and the notion of ?child perspective? and ?empowerment?.The results show that the child perspective is strongest on the web pages that represent the performative space as dominating and that empowerment is mainly represented as ?doing?, ?participating? and the ?free choice?.
Karaktärisering av hårdmetallpulvrets råvaror och dess påverkan på pulvrets flödesegenskaper
This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.
Så funkar avdelning C: en kvalitativ undersökning av användbarheten av SAB-systemets religionsavdelning i dagens svenska samhälle
The purpose of this thesis was to find out whether the main class C (religion) in the Swedish classification system Klassifikationssystem för svenska bibliotek is well adapted to classify materials published in or imported to Sweden, and handled by Swedish libraries today. The questions we put to ourselves were:1. How easy to understand, and how useful is the main class C religion today?2. What, in the main class C, is satisfactory?3. What, in the main class C, is inconsistent, anachronistic or incorrect?4. What, in the main class C, is in need of change or renewal?The method that was used was a number of interviews with librarians and cataloguers. We have interviewed eight librarians from six different libraries, of different types, but all with a relatively large collection of religious materials.Though all of our respondents have expressed a feeling that all the major religions deserve equal treatment in the classification system and a similar division of space, after some pondering on the subject, our respondents have agreed that a larger space for Christianity is warranted considering the composition of the current collections and publication. Our respondents have in some cases expressed that there is a lack of instructions as to how the subdivisions of the main class C (religion) is meant to be used.
Kanoper : Utanför Musiken
Jag har tidigare haft mina funderingar över att reflektera kring mitt eget verk och mitt eget komponerande. Funderingar om att det skulle bli för personligt och utlämnande. Det finns dock något spännande i att skriva om sig själv och sitt komponerande, en möjlighet att göra en resa inom sig själv. Så jag har i slutändan beslutat mig för att ta denna chans att skriva om mina tankar kring musik och om hur jag arbetar med utommusikalisk inspiration i mitt komponerande.Orkesterstycket Kanoper, den klingande delen av mitt examensarbete, är inspirerat av den egyptiska mytologin och gudavärlden; utan att jag är religös eller en anhängare av den gammelegyptiska tron, men jag har en förkärlek för det mytiska. Mytologi har varit ett stort nöje och en inspirationskälla för mig enda sedan jag var ett litet barn och jag lånade böcker om grekisk, egyptisk och nordisk mytologi fra?n familjens bokhyllor, först kanske mest för att titta på bilder men allteftersom jag lärde mig läsa så var det några av de första böckerna jag läste.
Växtmaterialet i 1700-talets engelska park : en växtplan för Engelska kullen på Gunnebo
Gunnebo House and Gardens was designed during the late 18th century by architect Carl Wilhelm Carlberg as a summer residence for the wealthy merchant John Hall Sr. and his family. The garden consists of formal garden, kitchen garden and English park. For the first two parts several original drawings have been preserved and here a lot of restoration work has been carried out. This paper aims to examine how the English park might have been implemented during John Hall Sr.?s time and to create a plant scheme for the area called ?Engelska kullen? (The English hill).
Hur bör unga hundar av storvuxna raser utfodras?
The dog is unique in the way that the adult weight can vary 100 folds between the different breeds. Despite this, most of the breeds reach adult size before two years of age. For the large-breed dogs this means a very rapid growth when some of them can have a weight gain of up to 150 times their birth weight. The most rapid growth occurs when the puppies are between three to six months old and that kind of rapid growth during such a short period of time makes these large-breed puppies very sensitive to deficits and excesses of energy, nutrients and minerals. Some examples can be excess of energy, excess or deficit of minerals such as calcium and phosphorus or deficits of protein.
The rapid growth can also make the large-breed puppies predisposed to some diseases affecting the skeletal and joints.
Genomgång av kemikalieförteckning som exempel på uppströmsarbete : en identifiering av utfasningsämnen i spillvattnet
Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.
Fosforavskiljning i reaktiva filter vid småskalig avloppsrening
An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.
Utveckling av en beräkningsmodell för biogasproduktion
A growing interest for the climate and the environment has led to an increased interest forenvironmentally friendly and renewable energy sources, such as biogas. Planning new biogasplants requires a decision basis including facts about approximate amounts of biogas possibleto produce at the plant. The purpose of this thesis is to develop a model that calculates theapproximate biogas and digestate production from a planned or existing biogas plant.Developing the model required a literature review and studies of calculations concerningbiogas and digestate production performed by WSP Sweden AB. As a complement to themodel development, facts about substrates for biogas production were compiled through aliterature review. In addition the methane potential from selected materials was determined bybatch experiments.

All entrepreneurs have to distinguish themselves in the extremely tight competition.This thesis examines how product photos can reach out to the consumers successfully. Both students have previous experiences from model shoots ? but now want to study the possibilities to sell a product without a human model.The purpose of the thesis is to examine how to convey core values by commercial product photos - how to best capture the attention of a customer.
Samband mellan testosteron, DHEAS, kroppskomposition och fysiska kapaciteter hos unga kvinnliga fotbollsspelare
Testosterone is a steroid and anabolic hormone found in all mammals. Previous research indicates that testosterone levels correlates with physical capacities related to physical performance. However, these studies refers only to men and boys. The aim of present study was therefore to investigate the potential relationship between body composition, strength, power and endurance capabilities in relation to blood levels of testosterone and DHEAS in young female football players. Seventeen female elite football (age: 15,4 ± 0,6, body mass: 57,2 ± 7,4kg, height 1,65 ±0,04m) players volunteered for the study.
