"Det är bara för oss att gilla läget" : livsmedelskagstiftning och livsmedelskontroll ur verksamhetsutövarens perspektiv : en kvalitativ studie genomförd i kommunala skolkök

This BSc thesis is a part of an initial step of a collaboration between Skansen and Kenyan Wildlife Service (KWS) and constitutes of an inventory of the Nairobi Animal Orphanage run by KWS. Animal Orphanage takes care of orphaned and injured animals arriving from throughout Kenya. The project started out as a refuge and as a temporary place for animals in need of care and help. With time it has evolved to an establishment that resembles and functions more like an animal zoo. The aim of this inventory is to focus on how the biological needs of Congo grey parrots ( Psittacus erithacus erithacus) and cheetahs (Acinonyx jubatus) are met, in terms of management and housing.

Effect of cow traffic system on cow performance and AMS capacity

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.

"The spirit of ayahuasca" : de kognitiva grunderna i erfarenheten av substansen ayahuasca: en fältstudie genomförd i Pisac, Peru

This essay aims at understanding the experience of the use of ayahuasca, and similarities and differences between interview protocols and socio-cultural identities. The work is based on field studies conducted in the Peruvian Andes, in the village of Pisac September to November 2009. What has emerged is that the experience does not seem to be dependent on cultural manifestations as much as it is dependent on general human cognition. Theories have been applied on an empirical phenomenological descriptive study. Various brain activities, along with mental mechanisms contribute to a deeper understanding of the findings in the descriptive analysis.It seems that the cultural differences, which I have classed as typological in the phenomenological study, mostly are expressions of meaning for the informants.

Gamification av digitalt lärande : En studie av attityder om spelelement i lärplattformar

Society today is characterized by the transforming effect IT has had, the majority of the activities we perform on a daily basis involves one way or another digital technology. One area which has not yet seen the positive effects of IT is education. Despite the progress of technology, the school education has barely changed since it first saw the light of day. Our goal with this study is to investigate the possibility of implementing Gamification elements in educational environments and examine whether it could increase our young students learning motivation. We believe that this kind of implementation will have a positive effect for these young people since they have been interacting with games since they were small and are familiar with the driving force of a reward system.With this study we want to examine the opportunities and challenges that Gamification implementation brings out in a learning environment and therefore encourage and motivate our young ones to study even harder..

Hållbart samhälle, hållbart liv : Om konstruktioner av ideal och problem kring social hållbarhet ur ett landsbygds- och äldreperspektiv

Social sustainability is often regarded as a solution to social problems in general.

What meaning and substance social sustainability is contained with as well as the effects that are produced by these conceptualizations is explored and analyzed. Also, the study examines the encounter between political policy?s and judgments on the one hand and the experiences and preferences held by the municipality?s elder inhabitants on the other..

Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics

The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.

"Pojkar blir på ett annat sätt än flickor ett ordningsproblem i klassrummet" : En intervju-undersökning av diskursen om pojkar och flickor i behov av särskilt stöd

This paper examines how remedial teachers and subject teachers in two secondary schools talk about pupils with special education needs (SEN) both in general, and more specifically about boys and girls who need special education. The study is based on 6 interviews with teachers in two secondary schools in the Stockholm area. In the analysis of the interviews, two different theories have been used. Firstly, the teachers´ speech has been analyzed based on three perspectives; a compensatory-, a critical- and a dilemma perspective (see Nilholm, 2007). Secondly, discourse analysis has been used to examine how the teachers in the study talk about boys and girls in the special education.

Biogas till kraftvärme på Wapnö : en projektanalys utifrån ett företagsekonomiskt perspektiv

Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure. The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.

On intersectional premisses, and with the help of a textanalysis, i will dress the data which i collected from one field of commentarys. The analysis is divided into themes in which and everyone i tend to immerse on that particular theme..

Urskogen med de stämpelbleckade gammeltallarna : en skogshistorisk tolkning av Brännlidens naturreservat

People have used forest resources in northern Sweden for different purposes. Before the 20th century the forest was used for many different reasons, but during the past 200 years it has become an industrial raw material. The presence of people in the forest has left different kinds of traces in the forests. One example is culturally modified trees (CMT´s). The aim of this study was to study and document how people have used the forest resources during the last centuries in Brännlidens nature reserve, and what kind of traces this land use has left.

Fredningseffekter och rekryteringsproblem hos abborre (Perca fluviatilis) i Stockholms skärgård

Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..
