The diffusion of architectural innovations : Modelling social networks in the ancient building trade
Within the project LATERES COCTILES early fired bricks have been the objectof a multifaceted investigation. One aim has been to elucidate the mechanisms behind the diffusion of this innovation. An inventory of Hellenistic and early Roman fired bricks around the Mediterranean resulted in an archaeological database comprising 276 brick contexts. Network analysis was applied to these data using a two
Scrubber liquid recovery in small and medium scale biomass gasification sysyems
Scrubbing is widely used in biomass gasification plants for tar removal. However, the cost of the scrubber liquid and its disposal once used can represent a non-negligible part of the plant operating cost. It is possible to lower this cost by regenerating and reusing the scrubber liquid by removing ash and heavy tars with the help of a centrifuge. Data from the two biomass gasification plants Hort
Laser spectroscopy applications for ecology and environmental monitoring
Optical spectroscopy, and in particular laser spectroscopy, has numerous applications in the assessment and probing in ecology, such as agricultural field and flying pest insect monitoring, as well as in the measurement of atmospheric pollutants. An overview of recent work by our group is given.
NOx-Conversion and Activation Temperature of a SCR-Catalyst Whilst Using a Novel Biomimetic Flash-Boiling AdBlue Injector on a LD Engine
Yearly 3.3 million premature deaths occur worldwide due to air pollution and NOx pollution counts for nearly one seventh of those [1]. This makes exhaust after-treatment a very important research and has caused the permitted emission levels for NOx to decrease to very low levels, for EURO 6 only 0.4 g/kWh. Recently new legislation on ammonia slip with a limit of 10 ppm NH3 has been added [2], whic

Slow electrons from intense laser-cluster interactions
A surprisingly dominant contribution of slow electrons is observed following NIR strong-field ionization of clusters. This is consistent with highly efficient intra-Rydberg correlated electronic decay processes, from which the emission of low-energy electrons is expected.

Early Middle Ordovician scolecodonts from north-western Argentina and the emergence of labidognath polychaete jaw apparatuses
Scolecodonts provide fossil evidence of the evolution and diversification of jaw-bearing polychaetes from the latest Cambrian onwards. However, their record before the Darriwilian (Middle Ordovician) is scarce worldwide, which limits our understanding of key evolutionary events. One such event is the emergence of taxa possessing the asymmetrical labidognath-type jaw apparatus architecture, which b
Separating effects of species identity and species richness on predation, pathogen dissemination and resistance to invasive species in tropical ant communities
Ants are abundant in natural and managed tropical ecosystems and can have an impact on herbivorous arthropods, as well as plant pathogens. Although it has been shown for plants that the diversity of communities can result in improved ecosystem functioning, it remains uncertain how the species richness of ants affects multiple ecosystem services and disservices. In the present study, we used experi
Nanoscale analysis of the oxidation state and surface termination of praseodymium oxide ultrathin films on ruthenium(0001)
The complex structure and morphology of ultrathin praseodymia films deposited on a ruthenium(0001) single crystal substrate by reactive molecular beam epitaxy is analyzed by intensity-voltage low-energy electron microscopy in combination with theoretical calculations within an ab initio scattering theory. A rich coexistence of various nanoscale crystalline surface structures is identified for the
Legal Power: The Basic Definition
The concept of legal power (often called legal competence) is important inthe law since, with regard to actions having legal effect, the “exercise of legal power” delimits those actions for which manifestation of intention to achieve a legal effect is essential for the effect to ensue. The paper proposes a definition that captures this feature of legal power and marks it off from “direct effect,” The concept of legal power (often called legal competence) is important in the law since, with regard to actions having legal effect, the “exercise of legal power” delimits those actions for which manifestation of intention to achieve a legal effect is essential for the effect to ensue.

Site-specific photocoupling of pBpa mutated scFv antibodies for use in affinity proteomics
Recombinant antibody libraries can provide a source of renewable and high-performing binders tailored for use in affinity proteomics. In this context, the process of generating site-specific 1:1 tagging/functionalization and/or orientated surface immobilization of antibodies has, however, proved to be challenging. Hence, novel ways of generating such engineered antibodies for use in affinity prote
Visual Odometry from Two Point Correspondences and Initial Automatic Tilt Calibration
Ego-motion estimation is an important step towards fully autonomous mobile robots. In this paper we propose the use of an initial but automatic camera tilt calibration, which transforms the subsequent motion estimation to a 2D rigid body motion problem. This transformed problem is solved 2-optimally using RANSAC and a two-point method for rigid body motion. The method is experimentally evaluated u
Kan ett ökat biobränsleuttag kombineras med god miljöhänsyn? : Resultat av en intervjustudie med skogsbrukets aktörer
Det är många maskiner och människor engagerade i en avverkning där man tar ut virke, grot och stubbar. En serie djupintervjuer med olika intressenter och aktörer visar att det finns stora brister i planering, logistik och kommunikation mellan de olika leden i kedjan, speciellt då flera olika entreprenörer är inblandade. Svaren visar också att det finns ett behov av bättre utbildning – och att man
District heating and cooling systems - Framework for Modelica-based simulation and dynamic optimization
Future district heating systems (so called 4th Generation District Heating (4GDH) systems) have to address challenges such as integration of (de)centralized renewable energy sources and storage, low system temperatures and high fluctuation of the supply temperature. This paper presents a novel framework for representing and simplifying on-grid energy systems as well as for dynamic thermo-hydraulic
