Hur biodiversitet på ekosystemnivå skiljer sig mellan olika habitat

Biodiversity can be described as the total variation of life forms, where diversity ranges from gene level up to the ecosystem level. The diversity can be calculated in a number of ways, and this study use one of these methods. In this study empirical food webs have been used and analyzed, where eleven characters are defined and used as parameters to calculate the Euclidean distances between food webs that describe the variation that may exist within classes of terrestrial, marine and freshwater habitats. The class who stood out and showed the greatest diversity at the ecosystem level was the marine food webs, which showed a high value of the average euclidean distance. The other networks were not as distinctive and the average of the euclidean distance in these classes was comparatively low..

Killar gör det grova, tjejer gör det andra: en studie om tjejers och killars syn på kön och genus

The purpose of this essay was to study how surroundings form young peoples gender and where gender patterns are maintained. This was done by interviewing 12 students from two advanced classes at a comprehensive school in a small town in the southern parts of Sweden. The students where divided into four groups. Two groups with three boys in each, and two groups with three girls in each. We used R.W.

Blodglukosmätarens betydelse vid mätning i hemmet på katter med diabetes mellitus

The choice of harvest date for leys is one of the most important factors affecting the size and quality of the harvest. An early harvest gives a high nutritive value while a late harvest gives larger quantity. Today?s aim to produce high nutritive leys gives early harvest dates both in primary growth and regrowth in northern part of Sweden. The consequence is a growth in the autumn, a "third harvest".The aim of this master thesis was to study the effects of different harvesting systems and their effect on size, feed quality, wintering and economy for conditions in the northern part of Sweden.

Demokratiuppdraget: ett viktigt uppdrag : En kvalitativ studie om hur fem lärare för årskurs 1 tolkar skolans demokratiuppdrag

According to the Swedish curriculum the education should establish respect for human rights and democratic values (Skolverket, 2011, s.7). The purpose of this study is to investigate how five first grade teachers understand the democracy education and how they practice it in reality. I have, based on the purpose of this study issued following questions:What is the teachers interpretation of the democracy education? How does the teachers work with democracy in practice?What difficulties does the teachers see with the democracy education?This study is made through a qualitative method based on interviews with five teachers. The results show that the teachers at both schools, despite the different definitions of the concept of democracy, yet interprets democracy education relatively equal.

Att möta ungdomars sexualitet på HVB-hem : En kvalitativ studie av hur behandlingspersonal upplever mötet med ungdomars sexualitet

The aim of this study was to investigate how staff members at residential homes experience encountering sexuality among the youths. The study was conducted by using qualitative interviews with four staff members at four different residential homes. The interviews have been analyzed by using content analysis and have been looked at through a perspective of experience, as described by Richard Stevens, and by applying developmental psychology. The results show that, although sexuality is experienced as being distinctly present and being a topic of major concern, the staff members have given sex-education as a means by which to raise their own competence little or no thought. One way to interpret this is that sexuality and sex-education haven?t been given a sufficient space in the work with the youths.

Diatermirök- Det perioperativa teamets arbetsmiljö

BackgroundDiathermy is the most commonly used surgical instrument in the surgical area today. Diathermy is used in surgery to cut and coagulate tissue. The use of diathermy releases chemical substances in to the environment in the form of diathermy smoke. Research shows that these chemical substances pose health risks to both staff and patient exposed to the smoke. To protect the interdisciplinary, perioperative team from the smoke, smoke evacuation systems can be used.ObjectiveThe purpose of the study is to highlight the work environment of the perioperative team when working with diathermy smoke.MethodThe study is meant to be implemented as an empirical descriptive sample survey.

Detection of mutations in dihydropteroate synthase (dhps) and dihydrofolate reductase (dhfr) in Plasmodium falciparum in eastern Sudan

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

Systemarkitektur och implementering av standardsystem : En fallstudie vid Linköpings universitetsbibliotek

The use of ERP in organisations is very popular and many companies have embraced this paradigm without really questioning why. Problems therefore often arise and cause high costs which is a result of poor planning. The paradigm also has its origin in the traditional architectural design that creates a system that has difficulties to adapt to organizations that are constantly evolving. The purpose of this study is to provide a different view of how IT-systems can operate within an organization and show how standard systems can be structured. We emanated from a case study at Linköping University Library, where we studied the implementation and integration of a standard system called Symphony.

Despotism och erotik: kvinnan och religion i Montesquieus Persiska brev

This study aims to investigate how, in Montesquieu?s Persian Letters (1721), religion and religious structures are presented to influence women?s position in French society.In Persian Letters Montesquieu presents a dogmatic religious life, which proceed from a literal interpretation of the bible. Such a reading raises critical questions concerning the nature of women, and subsequently places man over woman. Persian Letters show how this male dominance gets institutionalized in marriage. The religious life depicted is also distinguished by a non-genuine religious conviction and by acts which take on a simulation form.

Identitetens språk : Svensklärares attityd till dialekt i Värmland

The main purpose of this thesis is to analyze laws that completely prohibit abortion through a legal philosophical perspective. To demonstrate that abortion blanket bans cannot be seen as legally legitimate, the author has completed a literature study where she uses Robert Alexy?s ?Concept of Law? to analyze abortion laws both in general, and in Nicaragua in particular.Based upon Alexy?s ?Concept of Law? the author has identified three relevant key elements ? social efficacy, the argument from injustice and correctness of content - which she uses in her analysis. In order to apply these three elements on the total abortion ban, she then uses four different analysis tools - feminist theory, Human Rights, deontology analysis and right analysis. This has enabled a thorough analysis of the total ban on abortion that has demonstrates that such laws cannot be considered legitimate.By highlighting the human rights violations the law entails, one can conclude that the law has a social impact.

GRÄNSSNITTET OCH ANVÄNDARNA En undersökning av två gränssnitt mot en bibliotekskatalog.

The scope of this master´s thesis is the issue of usability in relation to interface design,in particular the interface of a university library´s online public accessed catalogue, orOPAC. Since the OPAC can be seen as the library´s ?shop window? to the world, it isof great importance that the interface to the OPAC can be used by patrons witheffectiveness, efficiency and satisfaction.The master´s thesis is based on a qualitative study performed at Karolinska InstitutetsUniversity library, and contains both a usability evaluation and an interview study. Twointerfaces were evaluated: a standard web interface provided by the system supplier, andan interface developed in-house by Karolinska Institutet´s systems department. The twointerfaces are both connected to the same online library catalogue, thus making possiblea comparative study..

Är uppdragstaktik och utvecklande ledarskap förenligt med utvecklandet av anpassningsbara officerare?

Människan har en förmåga att anpassa sig till en omvärld i förändring. Detta syns inte minst på den taktik- och teknikanpassning som sker i kampen mellan verkan och skydd inom den militära kontexten. Men idag sker inte bara förändring i den militära tekniken; även uppgifterna förändras. Exempelvis kräver de insatser som sker runt om i världen, inom ramen för FN-resolutioner, allt mer av civilmilitär samverkan samtidigt som enheterna måste vara ständigt beredda på att möta en motståndare i strid. Om anpassningsbarhet är det som gör att vi kan förändra oss för att möta nya uppgifter i nya miljöer torde ökad anpassningsbarhet i organisationen vara en fördel.Syftet med detta arbete är att undersöka huruvida de svenska ledningsstyrdokumenten, i form av Uppdragstaktiken (ledningsmetod-/filosofi) och Utvecklande ledarskap (ledarskapsmodell), är förenliga med utvecklandet av anpassningsbara officerare.Resultatet av analysen visar på god förenlighet mellan uppdragstaktik och utvecklande ledarskap å ena sidan och anpassningsbarhet å andra sidan.

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.
