Popular Abstract in English Our exploitation of yeasts, dating back to the Neolithic period, in fermented and baked foods remains deeply routed in societies due to their cultural and economic importance. Due to the long intimate relationship with yeasts, Saccharomyces cerevisiae, the “baker’s yeast” remains the organism of choice. However, there is an enormous biodiversity of other yeasts, termed Abstract: For millennia, the “yeast” Saccharomyces cerevisiae remains by far the most extensively studied and exploited yeast in food and industrial applications. A number of researches and developments have been done since the establishment of the biochemical function of yeast by Louis Pasteur in 1860, however modern lifestyles often connected to food related health trends demand new and innovati

The aim of this work is to build a framework that can be used for characterizing the bubbly gas liquid turbulent flow in the stirred bioreactor tank. To this end we have developed and modified techniques with which to measure the velocity of both dispersed gas and carrier liquid phases by the optical measurement technique, a 2-CCD camera Particle Image Velocimetry (PIV) system; and to characterize

Iran has one of the highest rates of road traffic accidents worldwide and according to a recent UNICEF report, the current rate of road accidents in Iran is 20 times more than the world average. Using extensive interviews with a variety of Iranians from a range of backgrounds, this book explores their dangerous driving habits and the explanations for their disregard for traffic laws. It argues tha

This literature survey aims at representing the current research on the cognitive aspects of the design activity, with an emphasis on problem-solving processes. The study is based on the selection of about sixty papers and books on the subject. The principal parameters of the study were defined as follows: general topics of the works, objects of the works, cognitive approaches, research results, s

Popular Abstract in Swedish Högt blodtryck, hypertoni, är en folksjukdom som ökar risken att insjukna i slaganfall och hjärtinfarkt. I flertalet fall är orsaken till hypertoni okänd och man talar då om primär hypertoni. Mellan 30 och 60% av blodtrycksvariationen i befolkningen bestäms av genetiska faktorer medan resten beror på omgivningsfaktorer. Primär hypertoni uppkommer sannolikt på grund av sGenetic factors are of importance for the development of primary hypertension (HT). Intrauterine growth retardation, salt sensitivity and insulin resistance are all characteristic features of individuals prone to develop HT. Monogenic forms of hypertension such as Liddle´s syndrome (LS) and Apparent Mineralocorticoid Excess (AME), and hypotension such as Gitelman´s syndrome (GIT) have recently bee

Popular Abstract in Swedish Produkter bestående av polymera material produceras i allt större omfattning. Materialen används därför i fler tillämpningar där deras specifika egenskaper kommer till användning. Materialens förmåga att modifieras för att passa en specifik tillämpning motiverar materialgruppens ökade betydelse. Idag används polymera material mer eller mindre i alla branscher t.ex. tranThe use of polymers and composite materials based on polymer matrix systems increases. With this raise the demands on recycling of both post-consumer and in house based material increase. The demands on the recycling process also increase. The reason is that the process more often has to be a part of the conventional production line. In order to incorporate such a process in a production line tech

This study explores the intonational signalling of a ‘request address’ in German and Swedish. Data from 16 speakers (9 Germans, 7 Swedes) were elicited under controlled conditions, and intonation contours produced on the test phrase “Wallander?” were classified according to their phrase-final pattern. Both ‘rises’ and ‘fall-rises’ were produced frequently by both Germans and Swedes, which is in li

Popular Abstract in Swedish I de flesta organ i människokroppen pågår en ständig förnyelse av celler för att kompensera för gamla cellers bortfall som en följd av skador och naturlig död. En ensam cell kan på egen hand kopiera allt sitt DNA och därmed all information den bär på, för att därefter dela sig och skapa en exakt identisk kopia av sig själv. Kodat i DNA finns instruktionerna för hur en oTelomeres are the end-structures of linear chromosome which are crucial for maintaining genome integrity. The telomeres prevent the DNA-repair machinery from recognizing the chromosome ends as double-strand breaks and from end-to-end fusions. The telomeres are composed by short repetitive units of TG-rich DNA and associated specialized telomere-binding proteins. Due to that replication only can

Qu'est-ce qui fait le propre de l'homme ?Comment la pensée humaine s'est-elle développée ?Pour tenter de répondre à ces interrogations fondamentales, Peter Gardenförs et son fidèle Egon, respectivement chercheur en sciences cognitives à l'université suédoise de Lund et macaque rhésus aux rares compétences linguistiques, partent sur les chemins des origines de l'homme, et cherchent à comprendre ce
