Extended One-Dimensional Supramolecular Assembly on a Stepped Surface

2,6-naphthalene-dicarboxylic acid was adsorbed on a Ag(110) surface with an average terrace width of only some tens of a nm. Scanning tunneling microscopy shows that the adsorbates self-assemble into one-dimensional mesoscale length chains. These extend over several hundred nanometers and thus the structure exhibits an unprecedented tolerance to monatomic surface steps. Density functional theory a

Niding

"Niding" is a historical novel set in seventh-century Scandinavia and Ireland.

Tourism social media as a fire object

Tourism studies have conceptualised social media as artefacts and networks of tangible objects based on neat distinctions and categorisations. Within the academic field of actor network theory (ANT) these neat ontological distinctions and categorisations have been problematised. John Law and Annemarie Mol are the scholars that most consequently have investigated the spatialities of messier ways to

Well Testing, Methods and Applicability

Well testing is widely used today in water wells, oil and gas wells, for geothermal applications, within civil engineering projects, thermal storage and CO2 storage. The overall testing goal is to verify the productivity from a well and/or for characterization of hydraulic and thermal properties, as well as the spatial limitations of an aquifer. There are three major methods for conducting well te

En utbildningsgaranti – möjligheter på regional nivå

Trots att gymnasiekompetensen är stark sammanlänkad med ungdomarnas framtida försörjnings- och etableringsmöjligheter framträder det i Skåne en dyster bild gällande ungdomarnas studieresultat (dock stora skillnader mellan kommunerna). Nästan hälften av Skånes kommuner ligger under riksgenomsnittet. När det gäller andelen elever som i årskurs 9 har uppnått målen i samtliga ämnen under våren 2013 är

Reducing Memory in Software-Based Thread-Level Speculation for JavaScript Virtual Machine Execution of Web Applications

Thread-Level Speculation has been used to take advantage of multicore processors in virtual execution environments for the sequential JavaScript scripting language. While the results are promising the memory overhead is high. Here we propose to reduce the memory usage by limiting the checkpoint depth based on an in-depth study of the memory and execution time effects. We also propose an adaptive h

Dramatic orientation shift of white-crowned sparrows displaced across longitudes in the high arctic

Advanced spatial-learning adaptations have been shown for migratory songbirds (1], but it is not well known how the simple genetic program encoding migratory distance and direction in young birds [2-4] translates to a navigation mechanism used by adults [2, 4-6]. A number of convenient cues are available to define latitude on the basis of geomagnetic and celestial information [7-15], but very few
