Koldioxidavgång vid ekologisk odling på organogen jord

The background of this work is the media discussion about the effect of cultivation on peatsoils on greenhouse gas emissions. It has been argued that row sown and intensivelycultivated crops such as carrots are more likely to emit carbon dioxide than for example grassleys. The association KRAV (an association promoting organic farming) shall, from this yearadapt their environmental policy to be more climate smart and have asked the question if thecultivation of some crops is more climate smart than others? Carbon dioxide emissions fromsoil are due to degradation of organic material and the rate is controlled by microbial activity.The microbial activity is determined by a variety of factors such as temperature, soil organicmatter quality and water content. I have measured the carbon dioxide emission from fourdifferent crops at two different farms.

Fyra lärares tankar och syn kring arbetet med integration, mångfald och värdegrund på en mångkulturell skola

The purpose of this qualitative research study is to examine if and how the teachers from a multicultural International School work with intercultural pedagogy. The school in question isprofiled and consists of both Swedish- and English classes. The study examines if and how the teachers related to the great variety of cultures and created opportunities for integration between the students and handling with values at school. It is important to be aware as a teacher to be able to take an active part in working towards a school that gives possibilities for different cultures to meet. If this is neglected, it may increase the risk of problems and cultural clashes between the students.

En heterotopologisk analys av den kulturella infrastrukturen i Göteborg: Rio Rio-båten på kollisionskurs med ett stadsplaneringsmaskineri på drift.

This essays overarching aim is to contribute to the theoretical discussion of transformation processes that are shaping the urban landscapes and further to problematize contemporary planning discourses in Sweden. Drawing on the concept of Foucault?s heterotopia and actor-network theory for spatial analysis, the paper seeks to analyze the complex urban landscape transformation process as an emergent property of human and non-human actor-networks seeking to transform and order space. With the district of Rosenlund in Gothenburg as a starting point, this thesis intends to examine how the cultural infrastructure - used by the residents and visitors of the city - are related to the city's planning and development processes. The case study is based on a boat (Rio Rio) in Rosenlund canal that is defined as a cultural infrastructure.

Den monokulturella mångkulturen i förskolan : En studie ur ett interkulturellt perspektiv om pedagogers tankar och uppfattningar kring ett kulturfrämjande arbete inom den mångkulturella förskolan

In the context of world globalization, Sweden has today become a multicultural society, where many different cultures, religions, values and approaches are trying to co-exist. When the Swedish government's integration policy was put into effect, one sought to open the way for a more peaceful coexistence between majority and minority people. The intention was that everyone, through mutual interaction, would learn to come together and learn to respect each other's differences. It was suggested that an intercultural approach should permeate all education, including preschool activity. There are particular guidelines for a culture and tradition promotion work within the preschool in the new revised curriculum (Lpfö 98, rev.

Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd

Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT. The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.

Plastfilmsöppningar till Tetra Paks förpackningar : En teknisk introduktion och tidig konceptutveckling

This master thesis is an early concept development project about using plastic films and sheets as materials for shaping openings for Tetra Pak packages. It is also a technical introduction highlighting the areas of importance for the development of plastic film and sheets openings. The master thesis has been carried out as a co-operation between Chalmers University of Technology, KTH Royal Institute of Technology and Tetra Pak AB.The master thesis study presents an introduction that gives an understanding of the technical complexities and design possibilities of using thin plastic films and sheets in liquid carton openings. The knowledge is then transferred into five design concepts which points out the areas of opportunity. The technical introduction is widespread and extensive covering current packing trends, the liquid carton package and openings, thermoplastic material properties, and thin film and sheet manufacturing and shaping.

Fritidsodlarens främsta försvar : trädgårdsväxter som skydd mot skadedjur

Fritidsodling är ett stort intresse i Sverige och det odlas trädgårdsväxter både för prydnad och för konsumering. Det finns ett stort antal skadedjur som kan förstöra växterna och reducera skörd. Denna litteraturstudie undersöker om det finns trädgårdsväxter som kan påverka skadedjuren negativt. Det ska göras genom att repellera/reducera skadedjuren, attrahera nyttodjur eller påverka odlingsmiljön och därmed stärka trädgårdsväxter att bättre motstå ett angrepp. Trädgårdsväxter som inte är typiska för skadedjuret att angripa kan förvilla dem genom att maskera värdväxtens lukt och därmed registrerar inte skadedjuret trädgårdsväxten. Utöver att maskera lukt kan vissa trädgårdsväxter även utsöndra flyktiga kemikalier som verkar motbjudande för skadedjuren och vara repellerande.

Ombyggnad av skolbyggnad för nya verksamheter : En visionsstudie för Wenströmska skolan och dess närområde

New production is not the only thing that is important for the city?s growth. It is also crucial to recover existing buildings in order to create attractive areas. There is a school in Va?stera?s city called Wenstro?mska skolan which consists of six high schools that provide different professional specializations and which has an area of about 35000 square meters.

Personnnummer non grata- En kvalitativ studie om hur uppfattningen om äldre arbetskraft påverkar de äldres situation i arbetslivet och vid rekrytering

The average age of the working population in Sweden is increasing, along with the number of retirements. Meanwhile, the number of people entering the labour market is declining. In order to avoid a loss of key skills and competences because of the resulting labour gap, and to ensure future economic growth, it is vital to utilise the aging labour force more efficiently. Nevertheless, many Swedish companies are inefficient in managing their aging workforce. In fact, it has emerged that senior workers in Sweden are discriminated against their age and not attractive on the labour market.

Syn på och handledning kring inkludering, neuropsykiatriska funktionsnedsättningar och matematik: : En kvalitativ intervjustudie om vilka framgångsrika handledningsmetoder specialpedagoger kan använda för att stödja matematiklärare som arbetar med elever

The basic principle of the integrated school according to the Salamanca Declaration is that all children, whenever possible, should be taught together, regardless of any difficulties or diversity. It has been shown that students with neuropsychiatric disorders are having much more difficulties to achieve the targets than the average student. Pupils with neuropsychiatric syndrome will always be present in school and we who are working in the business must be better at learning to adapt to them so that they too can achieve proficiency in school.Mathematics is perhaps the topic that Swedish students generally have most problems with,and it will not obviously be easier if you have some form of neuropsychiatric disability.In our future role as special education teachers, we will mentor and support other teachers in the complex educational environment that exists today. The aim that has been built up is thus partly to explore how mathematics teachers work with included students with neuropsychiatric disorders, as well as how teachers wishing to become supervised by specialeducation teachers in mathematics. The study is conducted from a sociocultural perspective.A sociocultural perspective on learning means that all people are learning all the time in social settings.

Emerging zoonotic viruses : what characterizes them and what are the risk factors for their emergence?

Emerging infectious diseases poses a great future threat, not only to humans but also to domestic animals and wildlife. Even though the majority of these infections only cause minor health problems, the relatively recent emergence of HIV clearly illustrates that the next major human pandemic may surface at any time. Regardless of what the name indicates, most emerging human pathogens are not believed to be recently evolved, but to have existed previously in the natural environment. Most emerging pathogens are zoonotic, i.e. able to infect animals besides humans.

Inventory and evaluation of Nairobi Animal Orphanage : focusing on spotted hyena, serval, Sykes' monkey, vervet monkey and on educational elements

The present BSc thesis is part of a newly established collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS), and constitutes of an inventory of the Nairobi Animal Orphanage (AO). As a refuge for wild animals found orphaned, abandoned or injured throughout Kenya, the AO has grown over the years and reached an unsustainable point where external help is needed for solutions and improvements. The aim of the inventory is to specifically consider the husbandry and enclosures of spotted hyena (Crocuta crocuta), serval (Felis serval), Sykes? monkey (Cercopithecus albogularis) and vervet monkey (Chlorocebus aethiops) and with the aid of facts about the species, estimate how well their biological needs are satisfied. Different educational elements are also reviewed since one of the main purposes of the AO is for education.

Ett elevperspektiv på sex- och samlevnadsundervisning i grundskolan : En retrospektiv enkätstudie bland gymnasielever

Public health is a concern of many important areas of society and it is therefore of great importance to examine and expand the goals of public health work within different sectors, e.g., school. Sexually transmitted diseases, sexual violence and mental health problems related to sexual orientation are some of the public health problems in society today. Throughout childhood and teenage years, norms and attitudes regarding sexuality and coexistence are formed, which means that school is an important arena when it comes to creating proficient conditions for    coexistence and sexual health. The quality of sex and coexistence education in Swedish schools differs in quality; for content and magnitude vary greatly among schools. It is, therefore, of interest to study how students experience sex and coexistence education, like prioritizations and desires.

Skolperspektiv på jämställdhet : En studie av grundskollärarens sätt att tala om jämställdhet i relation till flickor och pojkars resultat.

AbstractThe school today has an assignment to offset traditional gender patterns as well as to create opportunities for all pupils to achieve the same good results in school regardless of sex, ethnicity and conditions. The educator?s assignment is determined by governing documents, and the educator plays a role in helping the pupil find their equal role in society. This means that the educator needs to work in a way that offsets traditional gender patterns and require approaches that would benefit equal opportunities for both boys and girls to achieve good results.The purpose of the study was, through interviews, to get an idea of how primary school teachers from a gender equal perspective perceive how they see them relate to boys and girls in their teachings. The study is based on the presumptions that the pupils have but focusing on the relationship between school achievements and equality.The study brings up concepts like gender theories, equality, the biological sexes, the history of the schools development and changes in acceptance of boys and girls and the role of the governing documents to reach acceptable achievements.

GIS-baserad habitatmodell för mindre hackspett, ett verktyg för att bevara skyddsvärda lövskogar inom Umeälvlandskapet :

Deciduous forests are, according to the National Environmental Quality Objectives, a priority area. Deciduous forests are rich in species and the occurrence of dead wood is an important factor for biodiversity. In order to identify valuable deciduous forests for bio-diversity, conservation needs good analyses and planning tools. Habitat models combined with geographic information systems can be used to study the spatial structure of suitable habitat. The Lesser spotted woodpecker (Dendrocopos minor) has been proposed as an indicator species for deciduous forests, since this species is highly specialized on insect larvae in dead wood and requires large areas of deciduous-rich environments. Many riparian forest with high species richness and high nature conservation values are found along the Ume river in Umeå municipality.
