How Local are Spatial Density Externalities? Neighbourhood Effects in Agglomeration Economies
Andersson M., Klaesson J. and Larsson J. P. How local are spatial density externalities? Neighbourhood effects in agglomeration economies, Regional Studies. The geographic scale at which density externalities operate is analysed in this paper. Using geocoded high-resolution data, the analysis is focused on exogenously determined within-city squares (‘neighbourhoods’) of 1 km2. The analysis confirm
Effects of extracts of apple peel from organically and integrated production cultivated apples and ursolic acid on cancer cell proliferation
The effects of extract of apple peel, 'Aroma', organically cultivated or cultivated according to integrated production, on cell proliferation in vitro of colon cancer HT29 cells and breast cancer MCF-7 cells, were investigated. Different sequences of solvents were used, and the inhibiting effect on cancer cell proliferation of the different extracts was investigated. The solvents used were ethanol

Parameter Selection in the Parameter Estimation of Grade Transitions in a Polyethylene Plant
A polyethylene plant at Borealis AB is modelled in the Modelica language and considered for parameter estimations at grade transitions. Parameters have been estimated for both the steady-state and the dynamic case using the JModelica.org platform, which offers tools for steady-state parameter estimation and supports simulation with parameter sensitivies. The model contains 31 candidate parameters,
Moder Hesselblad och ekumeniken
Med anledning av den nära förestående helgonförklaringen av Elisabeth Hesselblad skriver nu Yvonne Maria Werner, professor på Historiska institutionen vid Lunds universitet, om moder Hesselblads syn på kristen enhet. Hur såg egentligen Elisabeth Hesselblad på ekumeniken? Vad är sant – och vad är myt? Yvonne Maria Werner reder ut begreppen.
Single Fibre Collection Efficiency : Infångningseffektiviteten för ett fiber
A personal computer program, FiFi, that makes a real-time two-dimensional simulation of the dynamic deposition process of particles on one or two fibres, has been developed. The code has been used to numerically calculate the collection efficiencies of spherical particles on a clean single fibre. The calculations are based on a 10 term expansion of a solution of Oseen's approximation of Navier-Sto
An Industrial Survey of Safety Evidence Change Impact Analysis Practice
In many application domains, critical systems must comply with safety standards. This involves gathering safety evidence in the form of artefacts such as safety analyses, system specifications, and testing results. These artefacts can evolve during a system's lifecycle, creating a need for impact analysis to guarantee that system safety and compliance are not jeopardised. Although extensive resear

Microanisotropy imaging : Quantification of microscopic diffusion anisotropy and orientational order parameter by diffusion MRI with magic-angle spinning of the q-vector
Diffusion tensor imaging (DTI) is the method of choice for non-invasive investigations of the structure of human brain white matter (WM). The results are conventionally reported as maps of the fractional anisotropy (FA), which is a parameter related to microstructural features such as axon density, diameter, and myelination. The interpretation of FA in terms of microstructure becomes ambiguous whe
Decarbonization under Green Growth Strategies? The case of South Korea
The win-win opportunities connected to green growth are appealing to academics and policy makers alike, but empirical evaluations about the effectiveness of green growth policies are still scattered. Taking South Korea as case study, which set up a highly ambitious green growth program in 2009, our research casts light on the extent to which the Korean Green Growth Strategy has been effective in d
Critical reflections on municipal risk and vulnerability analyses as decision support tools : the role of regulation regimes
Risk and vulnerability analyses are a required decision support tool in processes to improve societal safety and crisis preparedness at national, regional and local levels in several European states. Analyses result in risk images, which are the stakeholders’ views of events that must be addressed in planning processes related to topics such as land use and crisis management. Hence, risk and vulne
Challenges with risk and vulnerability analyses : Strategies for integration in risk and crisis management
Today risk analyses are commonly used by authorities at national, regional and municipal levels in their work to prevent and prepare for crises. The analyses provide information about types of incidents that can occur and the potential consequences of these events. In Sweden and Norway it is mandatory for local authorities to conduct risk and vulnerability analyses and use them as an input in thei
Whose mind? : Two interpretations of what it is to directly perceive other minds
According to direct perception theory (DPT) people understand each other’s minds by way of perceiving each other’s behavioral engagements in the world. I argue that DPT admits of two interpretations. One interpretation is found in Searle’s social ontology. The other interpretation departs from an enactivist account of social cognition. Both can be employed to make sense of what it is to perceive o

Master of puppets : Sculpting ancient worlds
Some extraordinary people have dedicated their lives to making art pieces out of long dead organisms. One of them is Esben Horn, founder of model shop 10 Tons Studios on the outskirts of Copenhagen, Denmark. A bona fide 'master of puppets', he makes jaw-dropping replicas for museums around the world, with the utmost respect for science and organismal anatomy. Recently, our joint efforts resulted i
