Theoretical results are presented on the absorption and fluorescence of indole in aqueous solution as well as at the air/water surface. We use a combined quantum chemical statistical mechanical model with explicit solvent. An approximate ab initio complete active space self-consistent field description of the indole molecule is used, coupled to a discrete polarizable water medium. From the bulk si
Popular Abstract in Swedish Att fasta under ramadan är både en glädje och ett jihad för det muslimska samfundet i Java, och fastan är utan tvekan den mest aktade ritualen i det muslimska Indonesien (och på andra håll i den muslimska världen). Att avhålla sig från mat, dryck och sexuella relationer från gryning till skymning i en hel månad i ett tropiskt klimat - och att fylla nätterna med extra frFASTING DURING THE holy month of Ramadan is both a joy and a jihad for the Islamic community in Java, and it is arguably the most highly esteemed Muslim ritual in Indonesia (and beyond). To be given the opportunity to abstain from food, drink and sexual relations from the early morning hours until sunset during an entire month in a tropical climate - only to fill the nights with additional and sup
We have computed the Galactic trajectories of 12 hypervelocity stars (HVSs) under the assumption that they originated in the Galactic Centre. We show that eight of these 12 stars are bound to the Galaxy. We consider the subsequent trajectories of the bound stars to compute their characteristic orbital period, which is 2 Gyr. All eight bound stars are moving away from the centre of the Galaxy, whic
Symmetric protein dimers, trimers, and higher-order cyclic oligomers play key roles in many biological processes. However, structural studies of oligomeric systems by solution NMR can be difficult due to slow tumbling of the system and the difficulty in identifying NOE interactions across protein interfaces. Here, we present an automated method (RosettaOligomers) for determining the solution struc
An exact treatment of the van der Waals interaction between two spherical dielectric bodies possessing purely classical degrees of freedom is presented. The spheres are described by multipole expansions of their fluctuating charge distributions, and the correlation between the fluctuations are taken into account using classical electrostatics and statistical mechanics. The presented approach avoid
The addition of amphiphiles grafted with polyethylene glycol units to constructs of DNA-amphiphiles is of most relevance for applications demanding colloidal stability. In this work, we study the self-assembly behavior of a true ternary mixture comprising (i) an electroneutral complex of DNA and a cationic surfactant (dodecyltrimethylammonium, DTA), (ii) water, and (iii) nonionic surfactant (dodec
What kind of citizenship education, if any, should schools in liberal societies promote? And what ends is such education supposed to serve? Over the last decades a respectable body of literature has emerged to address these and related issues. In this state of the debate analysis we examine a sample of journal articles dealing with these very issues spanning a twenty-year period with the aim to an
Accurate and internationally comparable Human Papillomavirus (HPV) DNA genotyping is essential both for evaluation of HPV vaccines and for effective monitoring and implementation of vaccination programs. World Health Organisation (WHO) HPV Laboratory Network (LabNet) regularly issues international proficiency studies. The 2010 HPV genotyping proficiency panel for HPV vaccinology contained 43 coded
In order to examine contemporary Russian cinema, this thesis has two points of departure: firstly the Petersburg myth, which is here defined as reversible or ambiguous since it includes both an eschatological and a cosmogonic aspect; and secondly, the Petersburg literary text as defined in works by Vladimir Toporov. During the twentieth century, the vitality and actuality of the Petersburg myth wa
The present study is about the phonetic properties of the West Swedish dialect spoken specifically in the city of Gothenburg, i.e. göteborgska. On the basis of a perception test using synthetic speech the present investigation concerns the distribution of segmental duration within stressed and post-stressed syllables in the task of identifying the West Swedish dialect. In this study I will use the
Gaia is ESA’s space astrometry mission with a foreseen launch date in early 2012. Its main objective is to perform a stellar census of the 1000 Million brightest objects in our galaxy (completeness to V=20 mag) from which an astrometric catalog of micro-arcsec level accuracy will be constructed. A key element in this endeavor is the Astrometric Global Iterative Solution (AGIS). A core part of AGIS
In the debate on the core of Information System (IS), El Sawy identified three faces of IS views: connection, immersion, and fusion. However, no research has further elaborated these concepts. For this task, we adopted the characteristics of the old concept of “emergence” to better describe and explain the shifts in IS from connection to immersion and finally towards fusion. A police organization
An increasing body of evidence suggests that a low-glycaemic-index (GI) diet has a therapeutic as well as a preventive potential in relation to the insulin resistance syndrome. The implementation of a low-GI diet, however, will require an extended list of low-GI foods to be available on the market. The tailoring of low-GI bread products offers a particular challenge due to their generally high GI
Image and flow cytometry was used to study the nuclear DNA content (ploidy) during the squamous cell carcinogenesis in the esophagus. The present retrospective study comprised 26 surgical specimens of squamous cell carcinomas (SCC) in patients who underwent surgery alone at the Department of Surgery in CHUV Hospital in Lausanne, between January 1992 and December 1999. We analyzed 53 healthy tissue
The molecular changes underlying neural progenitor differentiation are essentially unknown. We applied cDNA microarrays with 13,627 clones to measure dynamic gene expression changes during the in vitro differentiation of neural progenitor cells that were isolated from the subventricular zone of postnatal day 7 mice and grown in vitro as neurospheres. In two experimental series in which we withdrew
Sequence-dependent coordination of alkali ions to the nucleotide bases in the minor groove of AT-tract B-DNA has recently been inferred from X-ray crystallography, solution NMR and computer simulations. Here, we present new Na-23 and Rb-87 magnetic relaxation dispersion (MRD) data that demonstrate competitive and long-lived binding of Na+ and Rb+ ions in the minor groove of the B-DNA duplex [d(CGC
