The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with 180-deg turn under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase the blade tip lifetime. Di

Popular Abstract in Swedish DNA kan ses som en negativ laddad polymer som samtidigt har grupper som vill undvika vatten och därför bildas den karakteristiska dubbelspiralen. DNA och ett ytaktiv ämne (tensid) som är positivt laddad, bildar olika komplex. Dessa komplex är mycket mer kompakta än DNA själv. I denna avhandling har vi undersökt DNA och DNA-tensid komplex på olika ytor. Vi har använt oli

This account of genocide in the twentieth century contains a) a description of cases, b) an interpretation of different mechanisms of genocide and c) a comparative analysis of genocides as a historical phenomenon in the modern era. The text is divided into sections that are interrelated. The introduction gives a general background to the concept, describes the Genocide Convention and defines the

Background Major intrinsic proteins (MIPs) also named aquaporins form channels that facilitate the passive transport of water and/or other small polar but uncharged molecules across membranes. MIPs are particularly abundant and diversified in terrestrial plants but little is known about their evolutionary history. In order to shed light upon the origin of the plant MIP subfamilies 9 algal genomes

Building on Michel Foucault’s (1976) argument that a grand narrative of sovereignty characterised the idea of government and permeated entire systems of thought in the twentieth century, this paper asks whether Freudian psychoanalysis is also embedded within the same meta-discourse. Drawing on psychoanalytic accounts of Rebecca West’s work (Varney, 2000; Bonikowski, 2005) which tend to focus on We

Popular Abstract in Swedish Metan är en växthusgas med stor potential att påverka klimatet på Jorden. Den vattenmättade miljön i våtmarker erbjuder perfekta livsbetingelser för metanproducerande bakterier och detta medför att naturliga våtmarker är den största enskilda källan till metan i atmosfären, även då man räknar med antropogena utsläpp från, till exempel, förbränning av fossila bränslen. Mo

An improved understanding of the response of forest ecosystems to elevated levels of CO2 in the atmosphere is crucial because atmospheric CO2 concentration continues to increase at an accelerating rate and forests are an important sink in the global carbon cycle. Several CO2-enrichment experiments have now been running for more than 10 years, with highly variable short-term results after the first

Abstract Inducible plant responses to damage, i.e. inducible defence responses and compensatory growth responses, are theoretically examined in an evolutionary and ecological context. Inducible defences are generally considered to be beneficial under conditions of low risk of herbivory and when initial damage is moderate. This study indicate that under these circumstances, localized defence respon

Popular culture and tourism are intertwining. The use of film and literature amongst destination marketing organisations is a global trend, but how can we understand this phenomenon and all the processes involved? Up to now popular culture and tourism have been researched mainly from a single media perspective. However, it is difficult to separate the impact of one media product from that of anoth

With a worldwide increase in disasters, the effects of climate change are already being felt, and it is the urban poor in developing countries that are most at risk. There is an urgent need to better understand the factors that determine people’s capacity to cope with and adapt to adverse climate conditions. This paper examines the influence of formal education in determining the adaptive capacity

We present progress in the development of artificial photosynthesis, as a means to harvesting and storage of solar energy. The plan is to compose molecular systems that combine known photochemistry with emerging functional model compounds. A photochemical device for solar energy conversion contains a photosensitizer, an electron acceptor system and a donor system that prevents charge recombination

The innovation process is a challenge for companies trying to achieve better outcomes through new ideas or products. The related literature discusses the importance of innovation as a learning process, underlined by a design perspective. Supported by design, the innovation process combines multidisciplinary aspects of creativity and dynamism, mainly for end-user oriented industries. For other indu

As the identification process is based on the unique patterns of the users, biometrics technologies are expected to provide highly secure authentication systems. The existing systems using fingerprints or retina patterns are, however, very vulnerable. One’s fingerprints are accessible as soon as the person touches a surface, while a high resolution camera easily captures the retina pattern. Thus,

Popular Abstract in Swedish Populärvetenskaplig sammanfattning: (Popularized summary in swedish) I den här avhandlingen har vi studerat bindväven i brosk. Bindväv är ett samlingsnamn för de stödjevävnader som ger form och struktur åt brosk, ben, senor, hud etc. Bindväven skyddar även inre organ från yttre påverkan. Det är bindväven som ger brosket dess speciella egenskaper och som gör att brosketThis thesis describes chondroadherin, one of the leucine-rich repeat proteins in the extracellular matrix (ECM) of cartilage. Chondroadherin defines a subgroup of its own by not having an N-terminal extension, having a different cysteine pattern and by being devoid of carbohydrate substitutions. Here we show that chondroadherin also have a different exon-intron organization and chromosomal localiz

Popular Abstract in Swedish Metylisotiazolinoner. Diagnostik och prevention av allergiska kontakteksem. Konserveringsmedel är biologiskt aktiva ämnen som hindrar mikroorganismer som t.ex bakterier och svampar att föröka sig. Produkter som innehåller vatten behöver konserveringsmedel, annars kan t ex konsistens, färg och lukt förändras så att produkten blir oanvändbar. Hudvårdsprodukter, rengöring

Popular Abstract in Swedish Vid diabetes råder en oförmåga att hålla nere blodsockret, i synnerhet efter en måltid. Under normala förhållanden orsakar en höjning av blodsockret att insulinfrisättningen stimuleras. Insulin ökar upptaget av glukos i vävnaderna i kroppen, vilket sänker blodsockret. Under vissa förhållanden, såsom fetma, minskar effekten av insulin, ett fenomen som även kallas insulinThe parasympathetic nerves are important for the regulation of insulin secretion, in particular after meal intake. Apart from acetylcholine, several neuropeptides can be found in the parasympathetic nerves innervating the islets of Langerhans, including gastrin-releasing peptide (GRP) and pituitary adenylate cyclase activating polypeptide (PACAP). Exogenous administration of either GRP or PACAP ha

Some systems approaches tend to conceptualize social systems as collective entities, in which emergent properties of the whole can render individuals within a social system invisible. As critical systemic thinkers, however, we choose to see a social system as an emergent property of the interactions between unique individuals whose social relations are of interest. Thus, within the field of critic
