Hur anpassar sig Gyps-gamar (Gyps rueppellii och G. africanus) i Östafrika till oregelbunden och osäker födotillgång?
In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.
Effekten av formativ bedömning : En studie kring effekterna av formativ bedömning i anknytning till kunskapssyn, problemlösningsförmåga och attityd
This essay examines if formative assessment causes any impact on upper secondary school students results in social science. Other questions asked are which group of students benefits most from formative assessment and if any connections can be found between the students result and their cognitive approach to learning, problem solving capability and attitude to school.Two classes from a school in Stockholm were chosen to participate in the study. The theoretical framework is mostly based on former research performed by Black and William (1998, 2003). Multiple methods were used, including an experiment with a parallel-group design with two groups, a survey and a problem solving test. Statistics is used to describe and analyze collected data.Both groups were taught during five lessons in the same field of knowledge with the same kind of teaching, apart from formative assessment.
Foraging and anti-predation behavior of Thomson?s gazelles (Gazella thomsoni) and Grant?s gazelles (Gazella granti) at a waterhole
Prey species make behavioral decisions to reduce the perceived risk of predation and the time spent vulnerable to predation. Behavioral responses to predators are for example selection of specific habitat types and the presence of predators influence individual vigilance. Furthermore, there is a variation in feeding niches with different herbivores focusing their foraging effort on different vegetation types which is also expected to affect the choice of habitat. Behavioral data on anti-predation and foraging behavior at on waterhole is collected from Thomson?s and Grant?s gazelles at Ol Pejeta Conservancy (0°00?N, 36°56?E) located in semiarid bushed grassland in Laikipia district of central Kenya.
?Varför ska vi och dem alltid säras åt?? : En religionsvetenskaplig studie med fokus på representationen av den muslimska kvinnan i en västerländsk kontext
Research shows that Muslims are often reproduced within the context that reinforces stereotyping of Muslims, see for example Otterbeck and Schielke. They are often regarded as a collective group with no distinct individuals and thereby the Islamic religiosity is portrayed as different and deviant from the more secular and private practiced Protestantism that is a common belief in Sweden.The purpose of this work is to study the already existing representation of Muslim women in a Western context, i.e. Muslim women in Sweden. This is done through an analysis of two ethnographic interviews and observational studies, written by researchers in Sweden (Karlsson Minganti and Sultan Sjöqvist) to investigate the existence of an "us and them" mindset. The two ethnographic studies which are analyzed in this work, deal with different types of Muslims: women who have been Muslims since birth and converted Muslim women.
Kaninen som produktionsdjur
The purpose of this report was to obtain an overview of rabbit meat production in the world, in terms of breeding and feeding. It examines how different feed components contribute to the health of the rabbit as well as the quality of the carcass, and the breeding strategies that are most common in the major producing countries. The production of rabbit meat in Sweden is at present not very large, but it is gaining ground, and that is why this paper mainly deals with the rabbit production abroad. This report also examines the disease Rabbit Viral Haermorrhagic Disease (RVHD) in Sweden, where this disease can cause big problems.
The rabbit (Oryctolagus cuniculus) is very special, both in its reproduction and digestion. There is no specific mating season and the digestive tract is designed to digest forage efficiently.

Genusstrategier i förskolan : En studie av en förskolas arbete med att motverka traditionella könsroller, ur ett intersektionellt perspektiv
The purpose of this study is to examine a preschool's work to counteract traditional gender roles, which strategies are used and how norms about gender roles are produced and treated. The study also examines whether the preschool has an intersectional perspective in it's gender work, which analyzes how they relate to other categories such as ethnicity, race, class, age and sexuality in their work. I have been observing and conducting four interviews with teachers at a preschool with a gender profile. In my analysis I have used Foucault's theories about discourse and power. The results show that the informants had a high awareness of gender and that the main strategies used were: an individual perspective, seeing the individual and not the sex, and a gender-neutral strategy, removing everything that is gendered, for example, in language and environment.
Kvalitetssäkring av gjutgods till verktyg och utrustningar för karosstillverkning inom bilindustrin
Detta examensarbete är ett försök att skapa en enkel handbok, där man lätt kan slå upp fakta om olika typer av gjutlegeringar. Samtidigt är det en undersökning om hur man kan förbättra kvalitetssäkringen av gjutgods. För att uppnå det förstnämnda har grundliga litteraturstudier utförts och resultatet har blivit ett antal avsnitt som tar upp det viktigaste om gjutning och gjutgods. I dessa avsnitt kan man läsa om olika gjuttekniker, legeringars gjutegenskaper, olika typer av värmebehandlingar, gjutdefekter, vanliga metoder för kontroll etc. Undersökningen av kvalitetssäkringen, och om dess förbättring, möjliggjordes genom kontakt mellan olika företag och genom att prova tekniker, såsom finita element beräkning (FEM) och gjutsimulering, och dra slutsatser från dessa resultat.
Ungdomars fysiska aktivitet och dess betydelse för prestationen i skolan

Psykosocial arbetsmiljö och personalomsättning i restaurangbranschen
Denna kandidatuppsats behandlar ämnet psykosocial arbetsmiljö och personalomsättning i restaurangbranschen. Restaurangbranschen har den högsta personalomsättningen av alla svenska branscher. Då forskningen angående branschens arbetsförhållanden ur personalens perspektiv är relativt outforskad i dagsläget blir det angeläget att undersöka deras uppfattning om den psykosociala arbetsmiljön. Syftet är, därmed, att undersöka hur anställda på några à la carte-restauranger uppfattar den psykosociala arbetsmiljön samt om det har något samband med restaurangernas personalomsättning. Populationen för studien är à la carte-restauranger i Stockholms innerstad.
Upprepade ljusstimuli orsakar interferens i mörkeradapterade elektroretinogram hos hund : en utvärdering av några av European College of Veterinary Ophthalmology´s rekommendationer för elektroretinografi på hund
Electroretinography is an examination method where the function of the retina is objectively assessed. In 2002 the European College of Veterinary Ophthalmology (ECVO) published a proposition to a standard on how to perform ERG examinations, to facilitate comparison of results and to make it possible to repeat examinations.
The purpose of this study was to validate parts of the canine ERG protocol suggested by the ECVO. Our principal aim was to study if there is any interference at the recommended stimulus intervals for dark-adapted rod- and combined rod-/cone responses.
The results show that there is an effect on the a- and b-wave amplitudes when different stimulus intervals are employed. When all examined intervals are pooled, there is an increase in the median b-wave to each consecutive dim, white (rod) stimulus in a series of four.
Varbergs Societetspark 1856 - 2008 : en promenadparks förvandling
The Societety Park (Societetsparken) of Varberg here in Sweden, established in the year 1883 (1856), is one of the most famous parks in Varberg. Today it is, more or less, only used as a park that you will walk through in the wintertime, under the summer season though, the park starts blooming and then it is used for public music and singalong evenings. Earlier it was an old health resort park with its fine old traditions.The Societetsparken was a private owned park until 1902 when the town purchased it. On this plot there was already a smaller park and it was established as early as in 1856. It was called Badhusparken (The Public Bath Park) and it belonged to the hot- and cold-bathhouses, and these baths were very well frequented.
