This is the lecture that I gave when I was awarded Acta Ophthalmologica's gold medal and honorary award at the Nordic Ophthalmological Congress in Reykjavik in August 2010. I was inspired by Jared Diamond's famous book: Guns, Germs, and Steel, The Fates of Human Societies. Diamond is professor of geography and physiology at the University of California, Los Angeles. In this book, which won the Pul
BACKGROUND: Hyponatremia is the most common electrolyte abnormality and it is associated with increased morbidity and mortality. The aim of the study was to investigate the underlying causes and management of hyponatremia in an unselected population presenting with hyponatremia to the emergency department. METHODS: A descriptive, retrospective hospital record study was performed. A database search
This research focuses on representations of mobilities and their role in social networking on Facebook. Based on an ethnographic research design embedded in a grounded theory approach, the study investigates the mobility patterns of one Generation Y network. The analysis of 50 profiles in this network, including texts, photographs, photo albums and check-ins, suggests that Facebook fosters corpore

OBJECTIVE: To test whether a previously hypertension-linked 23 cM region on chromosome 2 is linked to the metabolic syndrome (MetS) or its individual components, and whether a common I/D polymorphism of the adrenergic receptor 2b (ADRA2B) gene, mapping in that region, is associated with the same traits. METHODS: We conducted fine mapping of the hypertension-linked region on chromosome 2 spanning b
Agila avtal är ett förhållandevis nytt fenomen och uppmärksammat begrepp. Fenomenet härstammar ursprungligen från ett agilt arbetssätt, som är särskilt utbrett inom IT-branschen. Traditionella avtal är upprättade utifrån förutsättningen att parterna redan vid avtalstillfället vet vad som ska levereras, när och hur. Det uppställs en uttömmande kravspecifikation vid projektets början. I ett agilt Agile contracts are a relatively new phenomenon that has gained increased recognition. This phenomenon originates from an agile approach, which is particularly widespread in the IT industry. Traditional contracts are based on a situation where the parties know what they need before the project starts. The requirements are set out comprehensively at the outset of the project. In an agile contract,
This thesis provides a self-contained introduction to the Fundamental Group and presents some of its applications, such as Brouwer fixed point Theorem,the Game of Hex, Nielsen-Schreier Theorem, the van-Kampen Theorem and some of its consequences, Borsuk-Ulam Theorem and some of its applications,the Jordan curve Theorem, and some other examples and applications.Some results in Group Theory will be
Enzyme engineering for a better future It is essential for many organisms on this planet to be able to digest plants. One of those organisms is the blue mussel, which uses certain enzymes in its stomach to break down sugar fibers in the algae that it eats. But how does this really work, and can we use it for anything? Plant cells have very strong walls, protecting them from environmental stress.
Thesis purpose: In order to contribute to Consumer Culture Theory, as well as critical dimensions in the foodie literature namely authenticity, democracy/distinction and gender, the study’s aim is to explore how discourses and socio-cultural meanings underlie identity constructions in the specific sourdough culture. Theoretical framework: As no research addresses the sourdough phenomenon directly
Present day aid strategies and their effectiveness are subjected to fundamental reassessment. Major donors and international financial institutions are increasingly basing their aid and loans to the countries on the condition that recipient governments undertake reforms that ensure "good governance" of the allocated funds. Present study conducted in November and December 2007 in Zambia w
This research is based on the investigation of a Biosphere Reserve in the South of Mexico. It observes the Vision and Mission of the Biosphere Reserve Sian Ka’an in Quintana Roo Mexico based on the norms given by UNESCO’s Man And the Biosphere. It also tries to examine the Reserve’s opportunity for sustainability science to be a knowledge co-production and exchange platform. And its prospects to b
This paper examines the effects of public and bank debt financing on firm performance in emerging markets. Using data on 742 publicly traded firms from the BRIC countries, it is documented that bank debt may have a positive effect on operating performance of a firm. This effect is more pronounced for financially distressed firms and during the crisis period. It is also found that bank debt has a U
Med sin ökade tillgänglighet på den kommersiella marknaden har eye-tracking blivit ett allmänt tillgängligt system för att analysera ögonrörelser. Detta har öppnat upp för nya möjligheter för utvärdering av usability inom humancomputer interaction, som tidigare har varit dyrt, tidskrävande och ofta utfört baserat på dåligt dokumenterade standarder och mål. Tidigare forskning har visat att eye-tracWith its increased availability on the commercial market, eye-tracking has become a widely accessible system for analysing eye-movements. This has opened up new possibilities in evaluation of usability in human-computer interaction, which has had a history of being expensive, time-consuming and often performed based on poorly documented standards and objectives. Previous research has indicated the
The growing need for green investments has contributed to the increased issuance of green bonds. This research investigates if green bonds are priced differently from conventional bonds by measuring yield spread discrepancies. To estimate the potential yield premium, we perform a matching method and a fixed effect generalized least squares estimator from October 2016 to December 2020. We observe t
In this work, lactoferrin was studied as a function of pH, starting at a low pH of 5.5 with 5 mM salt, in terms of interactions and dynamics with small angle X-ray scattering (SAXS), static and dynamic light scattering (SLS and DLS). Under these conditions lactoferrin was expected and found to have a strong electrostatic repulsion and behaved similar to an isotropic colloid. The glass transition w
