During the past 40 years brain tissue grafting techniques have been used both to study fundamental neurobiological questions and to treat neurological diseases. Motor symptoms of Parkinson's disease are largely due to degeneration of midbrain dopamine neurones. Because the nigrostriatal pathology is relatively focused anatomically, Parkinson's disease is considered the ideal candidate for brain re
Abstract in UndeterminedThe sedimentary ancient DNA (sedaDNA) technique offers a potentially invaluable means of investigating species evolution and extinction dynamics in high-latitude environments. An implicit assumption of the sedaDNA approach is that the extracted DNA is autochthonous with the host deposit and that it has not been physically transported from older source deposits or reworked w
The European Spallation Source (ESS), Lund, Sweden will be a 5MW long-pulse neutron spallation research facility and will enable new opportunities for researchers in the fields of life sciences, energy, environmental technology, cultural heritage and fundamental physics. Neutrons are produced by accelerating a high-energy proton beam into a rotating helium-cooled tungsten target. These neutrons pa
We have evaluated the efficiency of two popular end-point methods to calculate ligand-binding free energies, LIE (linear interaction energy) and MM/GBSA (molecular mechanics with generalized Born surface-area solvation), i.e. the computational effort needed to obtain estimates of a similar precision. As a test case, we use the binding of seven biotin analogues to avidin. The energy terms used by M
The extent to which sexual dimorphism can evolve within a population depends on an interaction between sexually divergent selection and constraints imposed by a genetic architecture that is shared between males and females. The degree of constraint within a population is normally inferred from the intersexual genetic correlation, r(mf) . However, such bivariate correlations ignore the potential co
The concept of ‘social return on investment’ (SROI) has come to play an important role in debates about how social enterprises and charities conceptualise, measure and communicate their achievements. In this paper we analyse the nature and role of SROI as used in the UK for impact assessment of such organisations. The paper offers insight into methodological and procedural aspects of the framework
In a previous publication [ P. A. T. Olsson, J. Appl. Phys. 108, 034318 (2010) ], molecular dynamics (MD) simulations have been performed to study the resonant properties of gold nanowires. It has been documented in the aforementioned publication that the eigenfrequencies of the fundamental mode follows the continuum mechanically predicted behavior when Bernoulli–Euler beam theory is used, whereas
The aim of this chapter is to contribute to the debate by arguing for an approach to validity in which (1) the domain of discovery and the domain of justification are brought together and are seen as being intertwined in a transactional sense, (2) the justification process is seen to be endowed with an experimential and a contextual dimension, and (3) a pro¬ces¬sual, historical pespective is thus
The article analyses the origins of the idea of the Swedish government in 1997 to initiate a project, Living History, to inform the Swedish people about the Holocaust.

Popular Abstract in SwedishMänniskor spenderar en stor del av sin vakna tid åt att tänka på saker som är orelaterade till den uppgift de håller på med eller den omgivning de befinner sig i (dagdrömmar). Under tiden man jobbar, läser en tidning, eller väntar på bussen kan manexempelvis börja tänka på något trevligt man ska göra nästa helg eller en tidigare deprimerande händelse som upprör en. DagdrMany individuals spend a substantial portion of their waking time thinking about topics unrelated to current activities and surroundings (mind wandering). This dissertation sought to contribute to our knowledge of why some people mind wander more than others. Mind wandering in cognitive tasks is more common in individuals with poor executive cognitive control (working memory updating, inhibiting t
