Cutaneous Melanoma in the Grey Horse
Equine cutaneous melanomas arise much more often in horses with a grey coat color than in horses of other colors. Some scientists have in different studies come to the conclusion that the melanomas are neoplasms which can be classified by examining their histological and macroscopic features. The more defined and demarcated a tumor is, the more benign it tends to be. Other scientists believe that the skin lesions are the result of a pigmentation disorder that is linked to the greying of the coat color. According to this theory, the lesions are not malignant although they have the ability to metastasize.
"Förbrända men icke förintade" : en osteologisk analys av kremerade individer från förromersk järnålder från gravfältet Smörkullen, Alvastra, Östergötland
Cremated remains have long been regarded as a highly complex material that often provides unsatisfactory results. This essay discusses the problems that arise when methods commonly used on unburned bone material are used in a cremated skeletal material. The present essay discusses the results from osteological analysis of seven cremations from Pre-Roman Iron Age from a large cemetery in Alvastra, Smörkullen. Several methods were ultimately not applied in the present study as they were insufficient for application on the relevant material. Since the methods were inapplicable and fragments available for gender assessments too low, no sex assessments were made.
Automatisk benplockare för lax : En vidareutveckling av befintlig prototyp
This thesis describes a further development of an existing prototype named Automatic pin bone remover. The further development was requested from the Swedish consulting firm ATM AB. The request of automatic pin bone removers is high and has the potential to be a worldwide leading product.The goal with the thesis work is to further develop an existing prototype. In order to achieve the goal a pre-study of the prototype had to be made in order to define a customer demand specification. The thesis work is then continued by a function analysis which differs from a conservative one.
Sambandet mellan parodontit och KOL
Chronic obstructive pulmonary disease (COPD) is a chronic lung disease. The disease is the fourth leading cause of death and more than 5 percent of the adult population worldwide is affected.The aim of this study was to investigate the association between periodontitis and COPD.Search for material for the literature review was done in the medical database PubMed where the keywords were: "Chronic obstructive pulmonary disease" and "Periodontal health or periodontal disease". The result is based on twelve studies that were extracted and analyzed. The studies have investigated pocket depth, attachment loss, plaque index, bleeding on probing and bone loss. Ten studies compared a COPD group with a healthy control group, one study compared two COPD groups and one study examined a COPD group and a group with other lung diseases.Most studies found that people with COPD had a higher incidence of pocket depth, attachment loss, plaque index, bleeding on probing and bone loss.
Comparison of two methods for evolving recurrent artificial neural networks for
n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

Samrådsunderlag för Lysekilsprojektet : Forskning och utveckling av vågkraft
The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.
Mysteriet med de spridda människobenen på Ajvide, Gotland : en studie om olika gravskick samt begravningsritualer under neolitikum
This essay includes an osteological analysis on the 1122 scattered human remains from The Pitted Ware culture site at Ajvide, Gotland. The scattered human remains have been found in the cultural layers, during archeological excavations at Ajvide between the years 1983-1987 and 1992-2009, where a burial ground was discovered. During the excavations, 85 skeletons graves were found, with complete and incomplete skeletons of 87 individuals. But aside from the graves, scattered human bones were discovered at The Pitted Ware culture site. One of the aims of the essay was to examine the bone material of the scattered human remains, and to determine whether this could possibly be a different type of burial custom than the skeletons graves.
Samband mellan testosteron, DHEAS, kroppskomposition och fysiska kapaciteter hos unga kvinnliga fotbollsspelare
Testosterone is a steroid and anabolic hormone found in all mammals. Previous research indicates that testosterone levels correlates with physical capacities related to physical performance. However, these studies refers only to men and boys. The aim of present study was therefore to investigate the potential relationship between body composition, strength, power and endurance capabilities in relation to blood levels of testosterone and DHEAS in young female football players. Seventeen female elite football (age: 15,4 ± 0,6, body mass: 57,2 ± 7,4kg, height 1,65 ±0,04m) players volunteered for the study.
Hundar kring benen. En analys av belastning och storleksvariation hos hundarna i det mesolitiska Skåne
This paper deals with variations in the osteological material of dog (Canis familiaris L.) from the Mesolithic Scania, southern Sweden. The general aim is to discuss the use and specialisation of dog during the period, and differences or relations between cultures and traditions within the Mesolithic period. The study is based on a analysis of the bone material from the sites; Ageröd I:A-D, Ageröd I:H-C, Bredasten, Bökeberg III, Hög, Löddesborg, Ringsjöholm, Segebro, Sjöholmen, Skateholm I-II and Tågerup, phase 1-3, with datings from Late Maglemose Culture to Early Ertebølle Culture. The seminar paper also includes descriptive statistics of the osteometrical data of Denmark, from several studies of Degerbøhl (1927) and Noe-Nygaard (1995, 2003). The study is focused on the relation between size, robusticity, muscle grooves and ligaments of mandibula, tibia, radius, humerus, femur and metacarpalia/metatarsalia.
Järnåldersgården som försvann : En studie av produktion, tafonomi och brända ben från möddingen vid gården Långåker från romersk järnålder
This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).
Dödsrikets livshistorier : Benkemiska isotopanalyser på artikulerade och disartikulerade individer i Frälsegårdens gånggrift
The aim in this thesis is to use carbon, nitrogen and sulfur isotope analysis on teeth and bone to track diet and mobility of the population as well as the individual level from the articulated and disarticulated individuals from the passage grave Frälsegården, situated in Gökhem parish in the region of Falbygden, western Sweden.50 human samples were analyzed from tooth, mandibula and femur, together with 11 faunal samples from different bone elements of local wild and domestic animals.The results fall well in line with earlier stable isotope work done on passage grave individuals from Falbygden in stable isotopes: A homogenous group with a diet which was clearly terrestrial and lived on a pretty high trophic level. It also seems that the analyzed individuals deliberately focused their food intake to the cultural and natural, megalith and limestone landscape of Falbygden, and not to its surroundings, even if the passage grave is situated in the outermost areas of the region.A small study compares the sulfur results to with earlier work done on strontium isotopes. The results show that the different methods might provide a deeper understanding in the interpretation of the methods, and therefore suggesting that further work should be done to compare the methods..
Hjälptyglars inverkan på hästen
The horse has been domesticated for several thousand years. It has gone from being used primarily for food and transportation, to become one of the most popular pets in Sweden. With over 150,000 practitioners, horseback riding is one of the biggest sports in Sweden and there is a variety of specializations to choose from. One orientation is western riding which is a broad sport with several disciplines where most originate in cattle work and other ranch tasks. Western riding is a growing sport in Sweden with an increasing number of practitioners and with many different organizations and associations, it is important that the correct knowledge of the equipment used is disseminated.
Artificial aids are available in a variety of designs and the most common variants used by western riders in Sweden is draw reins or some forms of martingale.

Prosamodernism, form och genusdebatt : En komparativ form- och receptionsstudie av Karin Boyes Astarte och Rosa Chacels Estación, ida y vuelta
The aim of this study is to compare the modernist novels Astarte (1931) by the Swedish writer Karin Boye with Estación, Ida y vuelta (1930) by the Spanish author Rosa Chacel and the reception of these literary works in contemporary academic research. The theoretical ground of the study consists of feminist and critical theory, with traits of discourse analysis.Astarte and Estación were in large part forgotten and ignored by the Western Canon of literature during most of the 20th century, but have lately gained more attention as important modernist novels by researchers (from the feminist, poststructuralist or hermeneutic theoretical fields) who primarily examine the experimental forms figured by the texts in relation to the deconstruction and shattering of human homogenous ?essence?.The results found in the study show that the literary forms of both novels can be associated with a kind of illusion rapture, which relate to the modernist inclination to what Frederic Jameson calls artificial narrative; a form technique that points back at itself to emphasize its own characteristic of being a constructed and subjective illustration of reality. The contemporary interest in these artificial literary forms expressed by Astarte and Estación is therefore probably a consequence of the vibrant academic debates carried out during later decades concerning the conception of human gender and identity as construction and performance. .
