Predatorinducerad fekunditet hos Daphnia pulex vid simulerade årstidsbundna temperaturvariationer

Female growth, number of eggs and egg growth of Daphnia pulex were studied at four temperatures, 12, 16, 18 and 20°C. I hypothesized that female growth and number of eggs would be lower and the size of the eggs larger in the presence of a predator (kairomones) than in its absence. This effect was expected to be more evident at lower temperatures. I could not find any effect of kairomones on female growth, number of eggs or egg size, although there was a weak tendency for an effect on number of eggs. There was, however, an effect of temperature, regardless of predator treatment (i.

Dubbeltydig form : Djurliknande avbildningar i metall under järnåldern

This study concerns a selection of prehistoric metal objects of animalistic design, published at the internet site of the Swedish Statens Historiska Museum. It seeks to give an impression of the design elements used, and to find likely models for the motifs among live animals. The method used is a qualitative hermenuetic comparative study of objects, where the distinct significant design elements are being identified and interpretated. Several significant design elements are identified, and some are interpretated as representing certain animals. The amalgamation of differentiating design elements in some objects however, leads to interpretations of compound animal motifs, where some motifs are considered ambiguous and some are rendered uninterpretated.

ALTERNATIVA ASFALTSBELÄGGNINGAR : Möjligheten att använda icke petroleumbaserade bindemedel

This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly.The main purpose of this report is to investigate whether there are any non-petroleum based adhesives on the market. If so, how can they be used? The questions covered are:? Are there any other alternative asphalt coatings available?? Can bio-oils be used in asphalt?? If the bio-oils can be used, what are the details their properties?? How does a cold climate affect the bio binders?? What is the Swedish asphalt industry?s opinion about bio asphalt?The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews.The conclusion of this report is that there are some existing non-petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas.

Vad gör de egentligen? En undersökning av bibliotekariers arbetsuppgifter

We have ourselves met misunderstandings about the tasks of librarians. The general opinion is that librarians are positioned behind the charging desk or are putting books on shelves. Other tasks are invisible and unknown to the public. The aim for this study is to explore the tasks that a selection of Swedish librarians does. The questions we have answered are: what do the librarians themselves claim to work with, which competences are necessary for this job, what does our study show regarding the librarian as generalist or specialist and finally; can the tasks that we find in our study help to understand the conceptions profession and status in relation to librarians.

"Det var synd att Süleyman Efendi måste dö" : En introduktion till den turkiska litteraturhistorien och presentation av Orhan Veli Kanik

The paper directs to introduce the turkish literary tradition to an fairly unknown european audience, as well as to present a turkish poet called Orhan Veli. Since there is hardly any literature written within this subject in either swedish or english I have come to the conclusion that the europeans have not yet been subjected to a discussion of this nature. For this reason my main task has been to gather and compose all that has already been written within this matter. I have chosen not to dig deep into such an unexploared subject, but rather offer different types of entries with which further research can be pursued and built upon.The early literature in Turkey consisted mostly of imitations of the well established arabic- and persian traditions. Because of that the turkisk modernism came, in comparison to the rest of Europe, relatively late.

Emerging infectious diseases : a model of disease transmission dynamics at the wildlife-livestock interface in Uganda

Emerging infectious diseases are a recurring threat to both human and animal health. Understanding the multiple causes behind the emergence of new diseases is key to the prevention of new and potentially devastating outbreaks. The list of underlying causes is long, including a variety of anthropogenic, environmental, molecular and climatic changes that promote the emergence and spread of disease. Two of these factors are central to the emergence of new diseases and receive special attention in this study. The spread of disease from wildlife to livestock and diseases that spread from animals to humans (zoonoses) are of importance as they implicated in the majority of EID events.

En man och hans ?pplen: en fallstudie av Carl Str?mbergs ?ppeltr?dg?rd

Mötesanläggningarnas framgångsfaktorer : En fallstudie av Stockholmsmässan och Stockholm Waterfront Congress Centre

The aim of this essay is to examine how important marketing and networking is for the meeting industry in Stockholm. The meeting industry is one of the most profitable areas of the tourism industry today and a major contributor to economic growth in Sweden. The meeting industry has grown rapidly in Sweden and Stockholm has during the last five years been one of the ten most popular congress cities in the world. This has resulted in that the city has become a strong competitor to other European cities.Stockholm International fairs are for example the largest trade fair organizer in Scandinavia and Stockholm Waterfront Congress Centre is the new arena of opportunity.However the marketing and a broad network is necessary for meeting facilities if their aim is to be successful. Marketing contributes to the meeting facilities establishment and makes it well known for the potential market, while the collaborations and relationships is important for facilitating their work.

Där jag aldrig varit

The sites I visit turned into routines a long time ago. Everywhere someone has decided what should be there and what will not fit. I retreat into my daydreams, away from everyday life. A longing for something different, something wonderful. I decided to go where I've never been, searching for something unknown.

Jordbrukets påverkan på Östersjön : en jämförelse av indikatorer för att beskriva näringsbelastningen

The Baltic Sea, due to its special conditions, is a unique and vulnerable marine environment. There are many pressures that have an impact on the sea and one of the major problems is the extensive flow of nutrients from land. The most visible effect of the supply of nutrients is the annual algal blooms. One of the main sources of nitrogen and phosphorus supply is agriculture. Nutrient losses from arable land have been increasing as agricultural production has intensified. At the end of the twentieth century an increased awareness of these problems led to the formation of organizations such as HELCOM and Baltic 21.

Upplevelser i samband med en obotlig cancersjukdom : En litteraturstudie baserad på vetenskapliga artiklar samt självbiografier

BACKGROUND: One of the nurse?s areas of responsibility is to relieve suffering. Research has shown that nurses give an indication of an emotional load in the interaction with dying patients. This means that patients need of relieved suffering gets disregarded because of nurse?s fear of the unknown.

Spelar tarmcellernas interna fettförbränning en roll i regleringen av födointag?

Since several lifestyle diseases are associated with obesity much research is carried out within the area. Researchers have found that oxidation of fatty acids within the body?s cells may give rise to peripheral signals which regulate food intake, but it is still unclear where such a mechanism takes place. Although much evidence suggests that it is the hepatocytes in the liver that send signals regulating food intake, some researchers have begun to question this theory. Instead they argue that the mechanism takes place within the enterocytes since they are well localised in the gut for such assignment.

Habitat preference and foraging behaviour in adult red-tailed monkeys (Cercopithecus ascanius)

The red-tailed monkey (Cercopithecus ascanius) is a small, alert and active animal inhabiting forests with dense vegetation and as such hard to observe in its natural habitat. The principal aim of this study was to scrutinize whether the methods, previously used in a behavioural study of the blue monkey (Cercopithecus mitis) can be applied in studies of the red-tailed monkey?s behaviour as well. Additionally, habitat preference and foraging behaviour of the red-tailed monkey were examined. The study was carried out between the 16th and the 22nd of March 2009 in the Sabaringo forest, located on the western border of the Masai Mara National Reserve.
