This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

Rotavirus causes diarrhea in young mammals all over the world, including infant humans. The diarrhea leads to severe dehydration that can be fatal if left untreated. The dehydration can be treated with fluid therapy and the infection heals itself. Despite the relatively easy treatment half a million children under the age of five dies every year due to diarrhea caused by rotavirus. Rotavirus sorts into the family Reoviridae and is a double-stranded RNA virus with a segmented genome.

Through millennia, humans have shaped the European landscapes. Agriculture, hunting andforestry have influenced virtually every ecosystem on the continent and formed what we todaythink of as the cultural landscape; a mosaic pattern of cropland, fields, pasture and forests. Thepast two centuries, globalization, industrialization and urbanization have come to pose a threatto the existence of these landscapes. European farmlands are now being abandoned at analarming rate, and the associated loss of landscape preservation, biodiversity and ecosystemservices is a concern to the scientific community and public alike.This thesis studies if the implementation of the relatively new conservation strategy rewilding(recreating self-sustaining ecosystems and reintroducing keystone species) can be a part of thesolution to preserve cultural landscapes and biodiversity in Sweden. Through interviewssupplemented with studies of published works, expertise from different fields has beencompiled to provide an overall picture of the capacity of rewildings as conservation method.

In a time of increasing urbanization the human tenure effects on the land has lead to a decrease and fragmentation of areas that are valuable to urban wildlife. These actions have had a detrimental effect on the species and habitats that exist in cities and towns.This paper investigates, through the study of relevant literature and the undertaking of interviews and field visits, the role that biodiversity plays in our society. The current attitude towards urban biodiversity and the responsibility for its promotion within the landscape architect profession has been explored.This paper includes three English case studies and a design proposal investigating how one can work to promote biodiversity on a smaller scale.This paper concludes that urban biodiversity is multi-functional ? being of ecological, social and cultural significance. The landscape architecture profession must be aware of the need to combine a variety of different factors such as economical, social and environmental aspects.

On the night of the 26th December 2011, large parts of southern Norrland were struck by the storm ?Dagmar? that caused serious damage to the forests. In the past 10 years wind damage has become a hot topic after several major storms. Forest companies own 25% of the Swedish forest and thus influenced largely by wind damage. The main purpose of this study was to examine whether forest companies attitude towards preventive wind damage actions were changed after the storm ?Dagmar?. The result was developed by doing interviews with two forestry companies.

Social mixing går ut på att ?mixa? befolkning av olika klasser i ett bostadsområde med syfte att förändra områdets sociala sammansättning. Syftet med uppsatsen är att undersöka social mixing som urban utvecklingsstrategi i Köpenhamn utifrån boendes egna upplevelser av sina bostadsområden. I Danmark definieras 29 bostadsområden som ?ghetton? utifrån kriterier rörande de boendes anknytning till arbetsmarknaden, ?icke-västliga? härkomst samt kriminalitet.

The aim of this review was to examine scientific literature to determine what kind of physiological and psychological benefits derive from human-dog interaction, as well as attempt to uncover a possible mechanism behind these benefits and whether or not they are mutually beneficial. A growing body of research indicates there are physiological and psychological benefits associated with human-dog interaction. Significant cardiovascular benefits have been linked with human-dog interaction, as have lowered blood pressure, cortisol and heart rate. Interaction with dogs is often associated with a feeling of social support and well-being, and dogs also seem to facilitate social interaction between people. Dogs? ability to buffer and reduce stress is also well documented. A strong indication was found regarding a relationship between physical contact and benefits associated with human-dog interaction.

The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

The aim of this study was to analyze the transtextual relationship between Hjalmar Söderberg's Jahves eld (The Fire of Yahweh, 1918) and the Book of Exodus. A limitation was set to just focus on the theme regarding the horned face of Moses, which Söderberg extensively discussed in his book, both through narrative and commentary. The methodological and theoretical approach could best be described as a qualitative text analysis where Gérard Genette's model of five types of transtextual relationships (intertextuality, paratextuality, metatextuality, architextuality and hypertextuality) was used in order to systematically classify the various relationships and in a thorough way relate the texts to each other.The analysis shows that the transtextual relationships are many and varied, and some appears to be more relevant to the study than others. Due to the composition of Jahves eld, its first part (?I österland, i fjärran tid?, most easily described as a paraphrase and pastiche of the Book of Exodus) can be identified as a hypertext to the Book of Exodus, while the second part (?Markels försvar?) is rather a metatext to both the first part and the Book of Exodus.

Cats and dogs are often unattended by their owners both indoors and outdoors, and therefore there is always a risk that they will get hurt. In the past, poisoning cases was considered unusual, but nowadays they are considered more common. As a veterinary nurse, it is important to know the common symptoms of poisoning, especially when working with emergency veterinary care. A very essential part of the profession as a veterinary nurse is to inform pet owners about the potentially dangerous substances and how poisonings can be prevented. The purpose of this report was to find out what is written scientifically about some common poisonings in dogs and cats and to present available statistics that covers the number of animals poisoned by various substances in Sweden. Hopefully this essay can also be used as a handbook for professionals in animal health care and to assist in educating pet owners. The report mainly covers groceries found in many homes, often easy accessible.

AbstractMy feature career as a teacher, for the early years of compulsory school, makes it interesting to finding out of how teaching religion can be donned. I am interested in what methods can be used for teaching religion That?s why my purpose aims to find out how five different teachers, of the early ages, works and what methods they use while teaching religion. My issue for this composition is: what methods, or to a point - methods supported by different teaching models, can be used for studying religion in compulsory school? Empirical and specialized literature points in the direction fore methods like storytelling, load reading, drama, group works, independent searching of information, working books and so on.

There are two species of potato cyst nematode (PCN), the yellow, Globodera rostochiensis, and the white, Globodera pallida. Each of them can appear in different pathotypes. These are separated by testing the nematode ability to multiply on a number of potato cultivars with different resistance properties. The aim of this project was to examine the virulence of Swedish and foreign PCN populations and to compare two test methods. Biotests are today the only available tests used to study virulence.

The park at Djäkneberget and its surroundings is a beloved area in the city of Västerås. The area is one of the most popular sites for outdoor life and recreation of all sorts and it attracts different kind of people at different times during the day. The park includes a pond-system where protected species of frog and toad live and breed. These animals have been the objects for many discussions concerning whether to explore the closeby areas or not. The prospected area is situated just next to one of the main ponds and consists of valuable foundationwalls were experts predict that the frogs and toads spend the winter. The municipality has now decided to restore this area to parkland. Because of the areas fascinating history I have chosen to do some research and give a short resume about it. For example are the existing park of Djäkneberget and its founder described together with a short description of the watersystem with the watertower that is situated in the area.

This thesis examines the organization Empower and their members, who consist of sex working women in Thailand. The purpose is to explore the more liberal point of view of prostitution and how the female members perceive Empower. Furthermore the study investigates if the organization can improve the sex workers empowerment. The study also delineates how these women reflect on their professional role as a sex working woman and whether the women relate to feminine discourses. The study is implemented in Chiang Mai, Thailand during the fall of the year 2010 and is based on qualitative methods like interview, focus group, observations and text analysis.
