The harbor porpoise is a small toothed whale with a widespread distribution, which spans the temperate and boreal waters of the northern hemisphere. As echolocating marine mammals, harbor porpoises rely heavily on acoustic signals, and it has been reported that vessel traffic can cause disturbances to these animals. The waters around the Kullaberg peninsula are an important breeding and nursing gr

Morphologically, the two corticoous species Rinodina pityrea and R. colobina are characterized by their dark blue-green blastidiate thallus and black plain or convex apothecia, with a light grey thallus margin. Rinodina pityrea and R. colobina are currently on the Swedish Red List as vulnerable (VU) and endangered (EN), respectively. They are hard to distinguish from Caloplaca chlorina in sterile

The continuously growing number of products containing nanoparticles makes their presence in the environment seem inevitable and given the well-known toxicity of dissolved metals, concerns regarding the toxicity of metal-based nanoparticles have been raised. Whether metal-based nanoparticles present similar or different toxicological effects compared to metal salts is a progressing field. In the p

Alpha-synuclein is a protein that has been found in Lewy bodies and Lewy neurites, which are filamentous aggregates that known are as the onset of Parkinson's Disease. The purpose of this study to investigate how the presence of phospholipid vesicles affect alpha-synuclein fibrillation different than when alpha-synuclein fibrillated in buffer, hydrophobicity during the aggregation process, mon

This dissertation explores the development of Asian American YouTube channels. Since the mainstream media are not offering any characters which are a fair representation of Asians, YouTube has become an outlet for Asian Americans to represent themselves. In order to break the general stereotype of a person of Asian descent, these YouTube channels post videos to empower Asians globally. Their succe

Popular science summary: Monitoring subcellular localization of Spx, YjbH, and ClpX in Bacillus subtilis Bacteria are exposed to continuous stress that causes damage to the cell. Therefore, they have developed stress responses that enable them to overcome stress and survive. Oxidizing elements is one kind of stress that bacteria have to deal with. To investigate how bacteria cope with this ki

Abstract Organically managed cereal fields have a higher plant diversity compared to conventionally managed fields. The presence and spatial distribution of plant resources may affect the spatial relationships between prey organisms and their predators and could therefore alter the feeding relationships between predators and pest prey. As invertebrate predators play an important role in biologica

In 2005 the United Nations International Law Commission released the report Fragmentation of International Law: Difficulties arising from the diversification and expansion of International Law. Although fragmentation of international law had been a topic of discussion long before 2005 the report really made the debate take off, becoming one of the most debated issues in recent years among internat

Sammanfattning En stor del av västvärlden står inför en demografisk förändring bestående av en allt åldrande befolkning i kombination med ett lägre barnafödande. För att möta detta behov förenklades 2008 det juridiska ramverket i Sverige gällande arbetskraftsinvandring från tredje land. Det nya regelverket innebär att den tidigare arbetsmarknadsprövningen togs bort, istället blev det den enskildeSummary Many Western countries are on the verge of a demograhpic change. This change consists of an aging population in combination with a decreasing birth rate. To meet the need following the labour shortage, the Swedish migration framework was modified in 2008. In the new framework the former labour market examination was abolished. Instead the individual employer became the decision maker of w

Populärvetenskaplig sammanfattning Bakterieflora och Antibiotisk Resistens i Gouldsamadinen Gouldsamadinen (Erythrura gouldiae) är en färggrann fink som lever i norra Australien. Arten har minskat i antal under de senaste decennierna och idag anses den vara utrotningshotad. I ett försök att stärka den vilda populationen har man genomfört återintroduktioner med individer från voljärer till artensAbstract The release of captive bred birds may be an important conservation tool for endangered species of birds. In Australia attempts have been made to re-introduce Gouldian finches in the wild and the same action is considered for other endangered Australian finches. This might pose a risk as a broad range of infectious diseases have been described in captive Australian finches yet little is k

Populärvetenskaplig sammanfattning: Geologisk bakgrund. För ca 200 miljoner år sedan, vid gränsen mellan tidsperioderna Trias och Jura, var Sverige en del av superkontinenten Pangea. Skåne låg vid kusten av ett större hav som täckte stora delar av Danmark. Klimatet var varmt och fuktigt och detta bidrog i hög grad till att de mer höglänta områdena i nordost vittrade och eroderades. Floder och andA palynological study has been conducted on Late Triassic and Early Jurassic outcrop- and borehole sections of the Höganäs and Rya formations, NW Scania. The diverse and generally well preserved palynomorph assemblages can be divided into three miospore zones: (1) the latest Rhaetian-?Hettangian Transitional interval; (2) the Hettangian Pinuspollenites-Trachysporites Zone; and (3) the Sinemurian C

The endemic mesosaurid reptiles of the Whitehill-Irati sea in southern Africa and South America during the Permian were studied with preference for the Namibian material. To date three valid mesosaurid species have been described of which two occur on both continents. These mesosaurid aquatic reptiles were among the first evidence used to support the theory of continental drift at the beginning of

This thesis investigates how two churches, Dómkirkjan and Hallgrímskirkja in Reykjavík, Iceland, can be seen to express Icelandic culture. This is done with a contextual and comparative analysis. Connections are made between societal development, geographical factors, cultural influences, and architectural traditions. Among other things the thesis shows a tension between international influences

Corporate sustainability research and practice are beginning to move beyond eco-efficiency. In our search to conceptualise sustainable development in terms that make sense to business, a growing range of frameworks, tools and management systems have emerged to support efforts to improve the social and environmental performance of companies. One of the challenges for business is to sort through the

The purpose of this report is to study the risk of dust explosions at the candy manufacturing plant Leaf Sverige in Gävle, Sweden. The risk analysis was conducted with a preliminary hazard analysis, PHA and event trees. The analysis focuses only on the risk posed to employees and material damages at the plant. No third person injuries have been considered. Another purpose of this report is to stud

The research examining the association between quality of diet and abdominal aortic aneurysm (AAA) is scarce. The aim of the present study was to explore the association between diet quality and development of AAA for middle-aged individuals in the Malmö Diet and Cancer Study (MDCS), a prospective cohort study with baseline data collection carried out between 1991 and 1996. At baseline, the study

Background: Inflammation related molecules such as tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6), and cardiotrophin-1 (CT-1) are highly expressed in obese individuals and could partly explain some comorbidities associated to obesity. In obese children, lifestyle interventions are able to lower inflammation and reduce cardiovascular risk factors associated with obesity. The aim of the prese

Hemicelluloses are a group of abundant polymers found in all plants and constitute about one third of the total plant biomass. These polymers can be used in many different products, such as oxygen barrier films, emulsifiers, foams and probiotic food additives. However, the commercial development and use of new products utilizing hemicelluloses has been limited due to the high production cost. Incr
