Observation of inclined EeV air showers with the radio detector of the Pierre Auger Observatory
2018
With the Auger Engineering Radio Array (AERA) of the Pierre Auger Observatory, we have observed the radio emission from 561 extensive air showers with zenith angles between 60 and 84. In contrast to air showers with more vertical incidence, these inclined air showers illuminate large ground areas of several km2 with radio signals detectable in the 30 to 80 MHz band. A comparison of the measured radio-signal amplitudes with Monte Carlo simulations of a subset of 50 events for which we reconstruct the energy using the Auger surface detector shows agreement within the uncertainties of the current analysis. As expected for forward-beamed radio emission undergoing no significant absorption or sc…
Reconstruction of events recorded with the surface detector of the Pierre Auger Observatory
2020
Cosmic rays arriving at Earth collide with the upper parts of the atmosphere, thereby inducing extensive air showers. When secondary particles from the cascade arrive at the ground, they are measured by surface detector arrays. We describe the methods applied to the measurements of the surface detector of the Pierre Auger Observatory to reconstruct events with zenith angles less than 60 using the timing and signal information recorded using the water-Cherenkov detector stations. In addition, we assess the accuracy of these methods in reconstructing the arrival directions of the primary cosmic ray particles and the sizes of the induced showers.

Los conflictos urbanísticos : sus causas y sus protagonistas. Una reflexión a partir de la experiéncia de Cataluña
2006
En Cataluña, durante los últimos años, los conflictos relacionados con el uso y la gestión del territorio entre la administración y la ciudadanía han aumentado, especialmente durante el proceso de elaboración y ejecución de algunos planes urbanísticos. Este artículo pretende analizar cuáles son las causas que los originan e identificar los actores que intervienen y, por lo tanto, fijará la atención en las estrategias de movilización que desarrollan los ciudadanos y los discursos que elaboran para poder incidir en el proceso de planeamiento, así como también en las actuaciones que la administración local realiza. In Catalonia, during last years, the conflicts related with the use and managem…
The planning research agenda: plural cities, equity and rights of citizenship
2010
Today it is self-evident that across the world we all -- more or less -- live in plural cities. A number of factors connected to development and underdevelopment processes as well as to the phenomena of social polarisation on a world scale are seen to be connected to this transformation. As a consequence, new, unexpected geographies are being created and old phenomena are taking new forms and dimensions. In this new geography of exclusion, fostered by the mechanisms of the new capitalist system and the crisis of the welfare state, inequality in cities is spreading significantly. What are the objectives and issues of planning research in these new urban circumstances? How is it possible to d…

A Practical Case of Participatory Meta-Action Research
2016
As already noted in the Introduction to this book, this chapter contains the only experimental contribution to this volume. Its basic purpose is to illustrate the degree of applicability of the most relevant concepts presented so far: namely, phenomenal forms, critical pedagogy, educational action research, and the pedagogical role of certain basic principles, and furthermore, to assess their potential to orient real situations of educational practice. Before the details of the specific research are presented, however, an introduction to the diverse forms of educational action research seems appropriate at this point, especially if this introduction is to help the reader to draw connections…
Structural Approaches to Explain the Selectivity of COX-2 Inhibitors: Is There a Common Pharmacophore?
2000
The identification and characterisation of the isoenzyme cyclooxygenase 2 (COX-2) stimulated investigations to develop efficient non-steroidal anti-inflammatory drugs with reduced side effects compared to standard NSAIDs. This review will focus on the structural features needed to achieve COX-2 selectivity. Five structural classes can be identified together with a class bearing little or no resemblance to one another in their molecular structure. The most interesting point is the very distinct structure/activity relationship. On the one hand only minor modifications to a particular compound induce a drastic change in its COX selectivity and on the other hand the structural prerequisites in …
Citizens AND HYdrology (CANDHY) : conceptualizing a transdisciplinary framework for citizen science addressing hydrological challenges
2021
Widely available digital technologies are empowering citizens who are increasingly well informed and involved in numerous water, climate, and environmental challenges. Citizen science can serve many different purposes, from the "pleasure of doing science" to complementing observations, increasing scientific literacy, and supporting collaborative behaviour to solve specific water management problems. Still, procedures on how to incorporate citizens' knowledge effectively to inform policy and decision-making are lagging behind. Moreover, general conceptual frameworks are unavailable, preventing the widespread uptake of citizen science approaches for more participatory cross-sectorial water go…
Joseph Conrad-Korzeniowski, an English Writer with a Polish Soul: Joseph Conrad’s Polish Heritage
2018
The article presents a portrait of Joseph Conrad-Korzeniowski, an English writer with a Polish soul. Conrad—the last Polish Romantic—did not only manage to introduce Polish dreams and longings into English (and Western) literature, but also transformed the Polish experience into a universal one. Writing about exotic, faraway places, he disseminated myths concerning Polish national identity, chivalric tradition and the Polish Eastern Borderland atmosphere and ethos. Conrad, a very demanding writer, never presents ready-made answers, nor does he offer simple solutions to the problems of his protagonists. Moreover, everybody can understand Conrad in their own personal way, for he is perceived …
