Specialpedagogiskt stöd i förskolan : En bild av förskollärares erfarenhet av specialpedagogiskt stöd

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.

This is a slightly less straight road to a conclusion than in the academic world that I amused to..

Verifiering av beräknad energiprestanda för flerbostadshus byggda år 2007-2009

The building industry consumes approximately 40 % of the total energy consumption in Sweden, where the using stage is dominating with 80 %. There is a lot of work in progress to reduce energy use in the building industry, and the demands from authorities regarding energy use increases. As a part of this work Building and planning department of Sweden has established a requirement that has been applied since 2006, and restricts a maximum energy use for buildings.The requirement includes that an energy simulation must be done in advance to demonstrate that it is possible to meet the demands.Reality is however more complex than an energy simulation program, that frequently underestimates the energy use of buildings. The purpose of this thesisis to study and analyse deviations between estimated and actual energy use in modern apartment buildings. The study includes four apartment buildings in Stockholm, Gothenburg and Jönköping that were built in 2007-2009.

Måste det vara så komplicerat? : En undersökning av attityder till klarspråk

The purpose of this essay is to examine what literary heritage teachers communicate in the school subject Swedish at upper secondary school. The overall research question for this work is: Which authors and/or works are mentioned by the teachers in the school subject Swedish at upper secondary school? How well do these authors and/or works answer towards a multicultural perspective? Which factors affect teachers´ selections of texts? Based on this purpose and these research questions, the aim is to answer the didactic question of what.To accomplish the purpose of the study a quantitative method has been used. The survey was conducted in two medium-sized cities in central Sweden, and was answered by 17 teachers. The study shows that the teachers ascribe the Western and Swedish literature great importance.

Källsortering och återvinning : upplevda problem, orsaker och tänkbara lösningar

We are soldiers, not policemen.Denna uppsats rör det vakuum som ofta uppstår när en regim faller samman på grund av krig, och dess ordningsmakt upplöses, eller av annat skäl inte förmår upprätta ordningen. Ofta inträffar plundring och upplopp i det ?polisiära? tomrum som inträffar från det att den tidigare regimens ordningsmakt drar sig undan, till dess att en ny poliskår träder in och bör-jar återupprätta lag och ordning. Av olika skäl frånsäger sig den intervenerande makten inte sällan arbetsuppgifter av mer ?polisiär? natur, alltifrån att bevaka samhällsviktiga byggnader till att dirigera trafik.I stor utsträckning följde kriget i Irak våren 2003 detta mönster från tidigare konflikter; ordningsmakten drog sig undan, plundring utbröt och koalitionen, bestående främst av USA och Storbritannien, nekade inledningsvis till att det var deras uppgift att ingripa mot laglösheten.

Design av utomhusträdgård i Dubai :

To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation. It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.

Skräckfilm och bilden inom bilden : En analys av rörlig bild inom filmen och dess reflexivitet i de japanska skräckfilmerna The Ring, Pulse och Dark Water

Syftet med denna uppsats är att skänka en grundläggande illustration av hur relationen bildinom bild och skräck kan se ut. Studien koncentrerar sig på estetiken och reflexiviteten hosbilderna inom bilden hos de japanska skräckfilmerna The Ring, Pulse och Dark Water. Dessabilder består av ett videoband i The Ring, webbkamerabilder i Pulse och övervakningsbilder iDark Water.Användningen av rörliga bilder inom rörliga bilder är reflexivt i den meningen att vimedvetandegörs om filmmediet självt som en konstruktion av bilder. Detta fenomenuppmärksammar oss också på akten att se. Syftet i skräckfilm är att skapa känslor av olust ochskräck hos oss och detta åstadkoms, bland annat, genom hur bilderna ser ut och är upplagda.Ett återkommande element hos bilderna inom bilden hos våra filmer är otydligheten hosflera av dem och detta att vi inte kan se bilden tydligt kan ge upphov till olustkänslor.

Spridning av släckvattenpartiklar : En studie på spridning av partiklar genererade från brand

During a fire large amounts of particles and unhealthy agents occur.  Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.

Underkambriska böljeslagsmärkens bildningsmiljö : Ett försök att fastställa fossila ripplars avsättningsmiljö med hjälp av recenta sandbottnar

ABSTRACTThe fauna of the Lower Cambrian is far from fully understood, as is the environment of that epoch. Some of the most crucial moments in the history of evolution takes place during this epoch; the Cambrian explosion and the appearance of ecosystems as we know them. That makes it an important period to investigate. Doing so, the Lower Cambrian offers a lot of problems, one of which is that body fossils are seldom preserved. That has often left us with trace fossils to create an image of the Lower Cambrian life, but also some bedrock features such as ripple marks.The main purpose of this work has been to investigate the possibilities of relating the wave lengths and forms of recent wave-generated ripples to fossil ones, and also to evaluate the methods for that kind of comparison.

Mineraliska material som reaktiva filter för avskiljning av tungmetaller från dagvatten

Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.

Sammankoppling av fjärrvärmenäten i Nyköping och Oxelösund : miljö- och systemkonsekvenser

District heating covers most of the residential areas and industries in the twoneighbouring Swedish municipalities Nyköping and Oxelösund. In Nyköping,Vattenfall AB Värme produces heat in a bio-fuelled CHP plant. In Oxelösund,waste heat and use of waste gases from the steel production at SSABOxelösund is the basis in the district heating system.This report examines the environmental consequences of a connection betweenthe two district heating systems. A broad system approach is used and the focusis on environmental effects in the system.A system analysis has been performed on the result of simulations of differentheat and electricity production alternatives. The alternatives simulated wereone where Vattenfall Nyköping covers the base load in the joint district heatingsystem and two where the power plant at SSAB Oxelösund supplies the heatbase load.The conclusion in this report is that the consequences of connecting the twodistrict heating systems can be both positive and negative, depending onsystem boundaries and on the environmental focus.

Fuktskador i bostadskök : En undersökning om fuktskador i kök och hur dessa kan förebyggas vid nyproduktion

Moisture damage in kitchens is an area that many people believe to be irrelevant andnot a subject to concern, however the problems encountered might be larger thananticipated.The purpose of this essay is to get a view of how problematic moisture damagecurrently is as well as what can be done to prevent damage during the constructionand building of new housing.Statistics regarding moisture damage as well as several tools for damage preventionhave been studied and investigated. Industrial regulations have been reviewed tounderstand the requirements construction companies must legally follow during theconstruction and building of new kitchens. Home manufacturers and largerentrepreneurs have been contacted in order to get their point of view regarding theproblems with moisture damages in kitchens.The knowledge of moisture safe constructions is prevalent by home manufacturers,insurance companies and entrepreneurs. Despite this knowledge, the constructioncompanies predominately follow the industries regulations, which normally onlyimplement the minimum requirements.In order to get construction companies to design and build kitchens with increasedmoisture security, stricter industrial regulations might be needed to be implemented.Unlike bathrooms and laundry rooms, kitchens are not defined as a ?wet room? andthe regulations for the construction of kitchens are more lenient.It is difficult to detect water leaks in an early state and the moisture damage is usuallyextensive before it is discovered and repaired if the kitchen lacks moisture securedconstruction and water security.

Driva tulpaner i näringslösning eller i jord :

The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands. There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.
