Kostnadseffektiv svaveldioxidreduktion : en studie dÀr ett optimalt svenskt mÄl jÀmförs med ett internationellt mÄl

In Sweden the work of reducing acidification and its prime cause; emission and deposition of sulphur dioxide, has been going on for decades. Despite of all the work that has been done the positive progress in the acidified areas is slow. This is partly due to a long recovery time for the acidified areas but also because the reductions of emission and deposition of sulphur dioxide have not been large enough. Emissions of sulphur dioxide from land based source in Sweden are estimated to 34 000 tons in the year of 2010. During the same year, approximately 182 000 tons of sulphur dioxide will be deposited over the Swedish territory.

Handdatorsystem vid fÀltbesök

Syftet med examensarbetet har varit att undersöka möjligheterna för ett system till SkogsvĂ„rdsstyrelsen VĂ€rmland/Örebro, dĂ€r uppgifter ska registreras i handdator vid fĂ€ltbesök och dĂ€refter verifieras och slutlagras i SkogsvĂ„rdsstyrelsens databaser. Under arbetets gĂ„ng har olika skogsorganisationer och företag intervjuats för att ta reda pĂ„ om de har nĂ„gon lösning som skulle kunna passa för SkogsvĂ„rdsstyrelsen. De lösningar som anvĂ€nds av andra organisationer/företag har analyserats för att fĂ„ fram för- och nackdelar med de olika varianterna. Slutprodukten innefattar inte nĂ„gon prototyp pĂ„ hur uppgiften skulle lösas utan föreslĂ„r olika verktyg som skulle kunna anvĂ€ndas. Arbetet har grundats pĂ„ litteraturstudier om införande av GIS i organisationer samt intervjuer och brevkontakt med personer och företag som arbetar med eller har kunskaper om fĂ€ltGIS.

Omstruktureringars betydelse för organisatoriska lÀrprocesser : Ett kunskapsperspektiv pÄ att dela en verksamhet och köpa verksamhetsnÀra it-tjÀsnter

The thesis aims to understand how learning processes are affected when an organization split into two separate organizations. The study is designed as a single case, covering a new government agency?s takeover of a core activity from another agency and the use of a purchase-provider split between the agencies, providing the new agency with IT-services. The findings revealed a difference in productive system and knowledge types between core- and IT-activities. The core activity was found to be dominated by explicit knowledge while the IT-activity seemed to be dominated by a mix of explicit and tacit knowledge.

Skapandet av ett byggnadsfysikaliskt detaljbibliotek Ät byggnadskonstruktörer : fokus pÄ fukt- och vÀrmetillstÄnd  i köldbryggor

Det konstrueras i stor utstrÀckning bristfÀlliga detaljlösningar pÄ byggnader i dagslÀget. Den bÀrande stommen i konstruktionen prioriteras ofta medan det inte Àgnas lika mycket fokus Ät att tillgodose de byggnadsfysiska aspekterna. Anledningen till de bristfÀlliga detaljerna Àr Àven att den som utför arbetet saknar rÀtt kunskap och tid. För att skapa en förbÀttring behövs ett hjÀlpmedel!Kunskap och erfarenhet om hur bra detaljer skapas finns redan i företag, svÄrigheten Àr dock att sprida kunskapen till de som Àr i behov av den.MÄlet med denna rapport Àr att skapa en metodik som blir startskottet för ett omfattande arbete kring framtagandet av ett detaljbibliotek, vars syfte Àr att sprida byggnadsfysiska kunskaper inom företaget och inspirera konstruktörer till att konstruera bra detaljlösningar. Biblioteket ska innehÄlla byggnadsfysiskt utredda detaljlösningar som analyserats enligt den utarbetade metodiken.

Selection of habitat and resources during migration by a large mammal : a case study of moose in northern Sweden

Migration is a worldwide phenomenon that has occurred for thousands of years in a vast variety of species. The general knowledge of migrating animals is poor even though billions of animals from a range of different groups migrate every year. The human impact on migrating ungulates is high and many populations are declining globally due to direct and indirect causes. Hence it becomes vital to study the migration phase and the habitat and resources selected during migration. The objective with this study was to identify the habitat characteristics and resource selection of moose during migration and compare the selection between different seasons and utilization distribution (relative frequency distribution for the points of location of an animal over a period of time) categories.

Francisella tularensis subspecies holarctica : the curious case of a water- and mosquito associated bacterium in Sweden

Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.

Samspel, etablering och koppling mellan naturgas och biogas

Sweden has a natural gas grid extending along the west coast, from Trelleborg to Stenungsund. There are also several smaller local networks where a planned natural gas pipeline from SkutskÀr to Hofors prompted the need for a comprehensive study. This study examines the linkages that exist in terms of technology and market of natural gas and biogas in Sweden. Sweden has set high targets for the future with ambition to become independent of coal and oil as energy sources. Since 1985, a part of the solution has been import of Danish natural gas.

Förenklad numerisk analys av hÀngbroars verkningssÀtt : Utveckling av programmet SusB med tillÀmpning av CalFEM toolbox

I Sverige tillverkas betong normalt med glaciofluviala grusavlagringar(naturgrus). PĂ„ senare Ă„r har tillgĂ„ng pĂ„ naturgrus blivit starkt begrĂ€nsade i vissa regioner och man vill av miljöskĂ€l minska förbrukningen av det som Ă„terstĂ„r. Återvinnig av material som kan ersĂ€tta detta Ă€r bĂ„de bra av miljöaspekt samt öppnar vĂ€g för produktion av betong med nya egenskaper.Med lĂ€ttballastbetong avses betong i vilken ballastmaterialet helt eller delvis bestĂ„r av nĂ„gon typ av lĂ€ttballast som har en partikeldensitet som Ă€r markant mindre Ă€n vad som Ă€r normalt för normala bergartsmaterial sĂ„som granit, gnejs eller kalksten. LĂ€ttballast Ă€r porös, dvs innehĂ„ller hĂ„lrum, och fĂ„r dĂ€rför lĂ€gre hĂ„llfasthet Ă€n normalballast. I lĂ€ttballastbetong bestĂ€mmer lĂ€ttballastpartiklarna mĂ„nga av betongens egenskaper, sĂ„som hĂ„llfasthet, elasticitetsmodul och krympning.Examensarbetets inledande del Ă€r en state-of-the-art rapport som omfattar tillverkning av lĂ€ttballastbetong i allmĂ€nhet, bĂ„de i fĂ€rsk och hĂ„rdnade tillstĂ„nd, samt dess bestĂ„ndsdelar med fokus pĂ„ skumglas som lĂ€ttballast.

Samspelet mellan naturbaserade arbetssÀtt och specialpedagogik: En kritisk studie

AbstractThis essay aims to problematize and illuminate the connection between special-education and nature-based activities. With a theoretical ground that is based upon a sociocultural perspective I consider the information from the field. Through a qualitative and critical perspective I performed individual interviews with five pupils from the sixth school-year in the Swedish elementary-school. I also performed Focus-group interviews with two educators and three teachers in the same school-form. By a Hermeneutical working-method I have found out that the informants in my survey have a common experience that activities performed in nature has a positive effect on learning.

Detta system förkortas BNWAS vilket stĂ„r för Bridge Navigational Watch Alarm System och Ă€r kortfattat ett dödmansalarm som syftar till att varna vid otillrĂ€cklig aktivitet pĂ„ bryggan. Detta system har funnits en tid men blir nu obligatoriskt ombord. Detta pĂ„verkar arbetssituationen och arbetsmiljön för vakthavande styrmĂ€n. Denna studie syftar till att undersöka vad styrmĂ€n som arbetar med systemet har för uppfattning och Ă„sikter om systemet.

Nedbrytning av vÀgar: JÀmförelse mellan axlar med singel- respektive tvillingmontage

When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.

Varför CSR?: En fallstudie pÄ SAS om orsaker till företagets arbete med Corporate Social Responsibility

The term CSR (Corporate Social Responsibility) is frequently discussed today. Many large companies work actively with CSR related questions. However, few empirical studies exist on what this work entails and why it is undertaken. Instead, most of the academic research focuses on what the term itself should mean. To bridge this gap this study centers on the employees? perceptions of CSR.

SkoltrÀdgÄrden i folkskolans miljö pÄ Gotland : med exempel frÄn Bunge- och Stenkumla skola

The thesis explores the phenomena of historic school gardens connected to elementary schools on Gotland, Sweden. Gotland had the highest percentage of school gardens connected to the elementary schools in Sweden, and by investigating this area much can be learned about the Swedish conditions. The study focus on the period in time when the school gardens were most frequent and used the most, to the point in time when they start losing ground. To bridge over the past to the present the thesis also investigates what is left and play with the thought of possible ways to treat the remains. The main question for the thesis is: How could a school garden on Gotland be constructed and be used 1907 ? 1947?And a follow up question is: What could still be there today and how can/should the remains be treated and conserved? The thesis begin with an overview look at the school gardens of Sweden, closes in with on Gotland and completes with a deeper investigation of two examples of school gardens; Bunge and Stenkumla elementary schools.
