Cinematography of neuroscience in the NetherlandsDe Magnus-Rademaker collection
No full textFollowing a short introduction on medical photography and cinematography, we describe a recently discovered neurological film collection, the so called Magnus-Rademaker collection (1909-1940), earlier presumed to be lost. Rudolf Magnus was professor in pharmacology in Utrecht and Gysbertus Rademaker was professor in physiology and later in neurology in Leiden. At the time they performed experimental research on animals to the role of the labyrinth, the neck afferents and cerebellum in position and standing. Next to animals, they also filmed patients. As an example we discuss a film about a boy whose cerebellum had been largely removed because of a tumor. The case was discussed for the ‘Amsterdam Neurologists Society’ and reported upon in the Dutch journal of medicine (1940). The films were produced for educational, as well as for scientific purposes. the discovery of this collection contributes to a better understanding of the role that early cinematography played in science and medicine.Peer reviewe

Hinders for Eco-friendly Media Selection
No full textThis study shows that, despite organizations claiming to care for the green environment through documented environmental policies, marketing communication such as advertising media selection does not seem to be much guided by green environmental concerns. Problems with consistency and control thus seem to exist between companies’ ideas/decisions (documented environmental policies) and their actions (advertising media selection), causing the need for justification and/or hypocrisy. This study adds to prior research on the non-use of models in practice by showing that the non-use of models also exists among marketing managers when selecting advertising media for marketing communication purposes. It was found that 64 percent of the marketing managers do not make use of media selection models. In the attempt to investigate differences in the factors guiding media selection between marketing managers who use media selection models (users) and those who do not use any model (non-users), it was found that the users take a medium’s eco-friendly characteristics less into consideration than the non-users. The paper discusses that the use of models can be viewed as attempts for making more rational decisions. The findings thus suggest that rational decision-making (users) may hinder eco-friendly media selection while non-rationality (non-users) may develop more powerful organizational ideologies such as acting responsibly towards the green environment. However, this study points out a link between the use of media selection models, previous experience and rules of thumb, i.e. the users tend to make more use of previous experience and rules of thumb than the non-users. Thus, the author argues that a new approach to model use may be needed and that the media selection should not be too much influenced by the marketing managers’ previous experience and rules of thumb. Otherwise, new factors may be overlooked such as consumers’ increasing concern for the green environment in relation to consumer advertising media attitudes. Previous studies have found that current approaches to marketing planning pay too little attention to the impact of technological advances on changes in consumer media habits. Thereby the risk may exist for focusing on mainly conventional media and not selecting “new media”. The present study seems to contradict these previous findings by showing that the selection of “new media” such as media using the Internet was found among the most selected advertising media by both the users and non-users for the two communication objectives studied, i.e. brand-building and to increase sales. Thus, the results indicate that while the marketing managers adapt their media selection to changes in technological media advances they tend to overlook consumers’ increasing concern for the green environment and the environmental aspect of advertising media. The results also show differences among the marketing managers in their selection of advertising media. At the same time as the non-users tend to be more precise with the recycling of paper, they are more inclined to select paper-based media such as catalogues and brochures than the users. The users on the other hand, tend to select more electronic media such as TV, radio and cinema than the non-users. In the attempt to explain the factors guiding media selection and in particular to what extent the environmental aspect of advertising media is considered, green environmental responsibility attitudes (GERA) of the users and non-users are assessed.Media Selection; Advertising; Green Environment; Marketing Managers; Models; Green Environmental Responsibility Attitude (GERA); Rationality; Non-rationality
Mode detection with an optimised array in a model turbofan engine intake at varying shaft speeds
No full textModal measurement techniques in engine intakes have been used previously to analyse the generated fan noise. A proven method is to use a wall-mounted array of Kulite transducers and operate the (model) turbofan under constant shaft speeds. A drawback of this method is the large number of (expensive) microphones and acquisition channels needed to obtain complete m-mode spectra at high engine orders. Furthermore, to get a full scan of the m-mode spectra as a function of shaft speed, many measurements are required. The issue of the large number of microphones was addressed by using a sparse array instead of an equidistant array. An array optimisation technique, similar to a technique used for the design of phased microphone arrays for sound source localisation, was used to define such a sparse intake array. This array consists of 100 Kulites and is able to determine without aliasing the modal spectrum from m = (79 to m = (79, which is appropriate to determine the modal content up to 3 BPF of a modern turbofan. This array was tested in a Rolls-Royce model fan rig at Ansty as a part of the RESOUND project. A new digital data-acquisition system made it possible to simultaneously and continuously record the Kulite pressure data as the engine speed was varied continuously from idle to maximum speed or vice versa, with each acceleration/deceleration lasting for a period of 9 minutes. Time histories of the Kulites were processed giving power spectra of the engine orders, which revealed the rotor locked tonal components. For each rotor revolution, a Discrete Fourier Transform was applied and, after averaging over a number of revolutions, the m-mode spectra were determined. In this way, a full modal scan with respect to shaft speed in a very limited testing time was obtained
Quantum Thermalization and the Expansion of Atomic Clouds
No full textAbstractThe ultimate consequence of quantum many-body physics is that even the air we breathe is governed by strictly unitary time evolution. The reason that we perceive it nonetheless as a completely classical high temperature gas is due to the incapacity of our measurement machines to keep track of the dense many-body entanglement of the gas molecules. The question thus arises whether there are instances where the quantum time evolution of a macroscopic system is qualitatively different from the equivalent classical system? Here we study this question through the expansion of noninteracting atomic clouds. While in many cases the full quantum dynamics is indeed indistinguishable from classical ballistic motion, we do find a notable exception. The subtle quantum correlations in a Bose gas approaching the condensation temperature appear to affect the expansion of the cloud, as if the system has turned into a diffusive collision-full classical system.</jats:p
Gate-tunable imbalanced Kane-Mele model in encapsulated bilayer jacutingaite
No full textWe study free, capped, and encapsulated bilayer jacutingaite (Pt2HgSe3) from first principles. While the freestanding bilayer is a large-gap trivial insulator, we find that the encapsulated structure has a small trivial gap due to the competition between sublattice symmetry breaking and sublattice-dependent next-nearest-neighbor hopping. Upon the application of a small perpendicular electric field, the encapsulated bilayer undergoes a topological transition towards a quantum spin Hall insulator. We find that this topological transition can be qualitatively understood by modeling the two layers as uncoupled and can be described by an imbalanced Kane-Mele model that takes into account the sublattice imbalance and the corresponding inversion-symmetry breaking in each layer. Within this picture, bilayer jacutingaite undergoes a transition from a 0+0 state, where each layer is trivial, to a 0+1 state, where an unusual topological state relying on Rashba-like spin orbit coupling emerges in only one of the layers
