Äldre människor i barnlitteraturen ? en studie av ett urval barnböcker från 2003-2006
The aim of this master?s thesis is to examine how elderly people are depicted in a selection of literature for children up to 10 years. The subjects examined are: lifestyle, roles and attributes. The books were collected from the databases ELSA and a local library, Borås stadsbibliotek. The books are analysed after a tool made by the authors.
Planering av design och skötsel i ett fragmenterat naturreservat
Rävsta naturreservat omfattar ett fragmenterat landskap som är mycket variationsrikt. När en skötselplan ska upprättas i ett sådant område är det viktigt att se till de hot som frag-menteringen medför som till exempel: för små habitat med för liten tillgång till resurser, avklippta spridningsvägar och kanteffekter. En ny skötselplan ska upprättas för reservatet under 2010 och det här arbetet syftar till att föreslå en modell som inriktar sig på att mot-verka de negativa effekterna som fragmentering har på den biologiska mångfalden. För att hitta de naturvärden som finns i området i nuläget har inventeringsdata från olika källor gåtts igenom. Data på arter som antingen är rödlistade eller indikerar höga naturvärden sammanställdes i olika grupper beroende på vilken naturtyp de är knutna till.
Handbok för växtinsamlare : med erfarenheter från sex nutida svenska experter
What makes a Swede betake himself into the Chinese wilderness? How does the Rio Convention influence a plant collector? And who will crack the nut positioned 12 meters up in the crown of a tree? There are many secrets behind the act of collecting plants.
In many regards, the documentation of the collection of plants for a Swedish purpose has been unsatisfactory. The focus of the publications is on what plant species that have been found rather than information on how these plants have been collected. Only few results of experimental cultivation are available. There is no doubt that there exists knowledge that has not been publicised yet.
Beteenden hos geparder i två stora svenska djurparker
Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.
Hägnutnyttjande hos Skansens lodjur (Lynx lynx)
Djurparker är idag stora attraktionsmoment samt arbetar också med bevarandearbeten. För att lyckas med ett bevarandeprojekt krävs det att djuren bibehåller sitt artspecifika beteende även i fångeskap vilket kräver ett bra hägn med tydliga mål. Det europeiska lodjuret är ett relativt populärt djur i djurparker i denna del av världen, och är än så länge inte hotade. Dock gör minskade habitat, avskjutning samt förändringar i bytestillgång att lodjurspopulationen minskar. På Skansen hålls två lodjur, en hona och en hane, i treårsåldern tillsammans i ett hägn.
Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0
After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.
Patterns of Touch : En analys av touchspel till iPad utifrån gränssnittspatterns
For this essay we used pattern theory from interface design and applied it in an analysis of touch games. In order to make full use of the patterns, we selected five of them and adapted these slightly with the help of game related patterns to be useful for the framework of this essay. The selection of games were the top eight games on the App Store?s ?What?s Hot?. The results showed, among other things, that the games had a clear focus on getting a pleasant apperance, and they did it relatively well.
Prislisteoptimering för ett sågverk - Jarlträ AB :
This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU. The work was an assignment from Jarlträ AB which is a privately owned sawmill located in southern Småland. The aim of the work was to investigate the economical result of different pricelists and how to adjust different parameters such as length correction to give an optimal result.
The pricelists was examined through a computer program (SilviA). The pricelists was made in the program and after that a simulation was preformed with a selection of random sampled trees gathered from the area nearby the sawmill.
Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana
In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself
better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure.
The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.
Barns självvalda läsning
The purpose of this thesis is to gain insight into children`s voluntary reading in their spare time. I have focused on printed books and none of the digitally published Medias. I want to examine how children experience the power adult`s exercise over their chose of books and also why they choose the books they do. The method of this study is qualitative with interviews of six 10 years old children. I conducted the interviews detachedly and I have used two different point of view for my study; Aidan Chamber`s ?Reading Circle? and Barbro Johanssons opinions if children`s participation in terms of their voluntarily book selection.I have also studied other researchers and author´s writings about literacy, children´s reading habits, adults´ attitudes to children´s reading and children´s passion for reading.During my study it became clear that children who like to read prefer to read detective stories for children, a result that also earlier investigations reached..
Vilken vikt har ett klander? : En kvalitativ studie av hur ansvariga utgivare förhåller sig till PON:s beslut.
The purpose of this study was to find out how the responsible editors on a selection of Swedish newspapers react to a reproach from the Press Ombudsman. The method for this research was eight qualitative interviews with responsible editors on some of Sweden?s biggest newspapers, and also a few local newspapers.We based our results on the interviews and three theories ? media accountability, communicative action and consequence neutrality. We used these theories because we think that, put together they produce the most apt view of how media ethics is being handled in the printed press.We found out that in most cases a reproach doesn?t mean that much to a newspaper.
Att Synliggöra det Osynliga : GIS som verktyg i sökandet efter bosättningsområden från bronsåldern på Gotland
In this bachelor essay an attempt is done, to recreate a probable Bronze Age landscape on Gotland, with GIS as a tool. The landscape on Gotland is situated with many different monuments dated Bronze Age, such as cairns and stone ships. In creating of the maps, two possible shorelines contemporary with the Bronze Age have been calculated and marked on the maps. Furthermore, peat lands have been drawn upon the maps, by using the information from geological maps.A landscape variable have been compared between Bronze Age places and Early Iron Age houses; the soil type. On Bronze Age places gravel is the most common, while moraine marl is the most common on places with Early Iron Age houses.From a selection that were made, all Bronze Age places where within 3 km from the water, either the recreated shoreline or peat land.

Undersökning av potentiella probiotiska organismer i tarmmikroflora hos häst med speciell hänsyn till Lactobacillus spp. :
The aim of this study was to isolate and identify Lactobacillus species indigenous to the gastrointestinal microflora of Swedish horses. These lactobacilli are to be used as probiotic candidates in research concerning antibiotic-associated diarrhoea in horses.
Eight horses, age 6-10 years, were selected from a riding school for collection of faeces samples. Man Rogosa Sharp medium and gram staining were used for the selection of supposed lactobacilli. We could identify 33 isolates of supposed lactobacilli. With the use of API tests 22 of these 33 isolates could be identified.
IT-outsourcing ? dolda kostnader
Many corporations turn to IT-outsourcing to focus more on their core competence or to cut the IT-budget. There is one caveat, the costs presented at a first glance does not always present the entire truth. Instead the costs run deeper and so-called hidden costs exist beyond the contractual cost. Reducing these hidden costs may very well be crucial to the entire IT-outsourcing endeavor. However many firms are not aware of these costs and as such they have a reduced chance of success.
