Partial Wave Analyses of the pp data alone and of the np data alone
We present results of the Nijmegen partial-wave analyses of all NN scattering
data below Tlab = 500 MeV. We have been able to extract for the first time the
important np phase shifts for both I = 0 and I = 1 from the np scattering data
alone. This allows us to study the charge independence breaking between the pp
and np I = 1 phases. In our analyses we obtain for the pp data chi^2_{min}/Ndf
= 1.13 and for the np data chi^2_{min}/Ndf = 1.12.Comment: Report THEF-NYM 94.04, 4 pages LaTeX, one PostScript figure appended.

Sensor Concept for Controlled Laser Cleaning via Photodiode
Abstract. In the field of laser cleaning of artworks the effect of “over-cleaning” is a commonly well known problem. The detection of laser induced plasma is one possibility in order to identify the kind of material just being irradiated by the laser beam. LIBS is a powerful method for the extraction of spectral information. Instead the detection of the plasma intensity contains much less information. However, this can be realised by using a fast photodiode. It has turned out that for several applications in laser cleaning of artworks a reliable identification of layers during the cleaning process is possible. In cooperation with restorers we proved that this low-cost method may be used for online monitoring as well as automated closed loop cleaning.
Normen en Waarden in het Bedrijfsleven
Een onderzoek naar het belang van Maatschappelijk Verantwoord Ondernemen voor de Humanistiek.
Het thema Maatschappelijk Verantwoord Ondernemen (MVO) lijkt bezig aan een onstuitbare opmars. Bedrijven die deze vorm van ondernemen aanhangen streven naar een balans tussen mens, milieu en financiële winst, ook wel people, planet, profit genoemd. Innovaties, nieuwe samenwerkingsvormen en sociale en duurzame ontwikkelingen volgen elkaar in rap tempo op en netwerken van MVO-ondernemers groeien elke maand. Binnen de Humanistiek wordt weinig aandacht aan het thema besteed. Dit terwijl het een concept is dat meer ruimte lijkt te creëren voor morele waarden binnen het bedrijfsleven, humanisering van systemen en zingeving van de mensen die binnen de MVO praktijk werkzaam zijn.
Dit afstudeeronderzoek is daarom een eerste brede verkenning van het belang van MVO voor de Humanistiek. Er wordt bekeken in hoeverre MVO kan bijdragen aan de ontwikkeling van twee domeinen die op het eerste oog veel verwantschap vertonen met de uitgangspunten van MVO: Kritische organisatie- en interventiestudies en Normatieve Professionalisering. Aan de hand van literatuuronderzoek en de analyse van interviews met mensen werkzaam in de MVO praktijk, wordt duidelijk dat het interessant en belangrijk is om vanuit de UvH meer aandacht te besteden aan dit thema. Zeker omdat we andersom, vanuit onze kennis en expertise rond onder meer morele leerprocessen, organiseren, zingeving en humanisering, ook veel te bieden hebben

Influence of temperature gradients on mono- and divalent ion transport in electrodialysis at limiting currents
Temperature gradients in electrodialysis (ED) stacks can potentially enhance the efficiency of charge separation and the selective transport of ions. We have previously investigated temperature gradients in the Ohmic regime but not in the limiting current regime, where diffusion of ions towards the membrane determines the transport rate and temperature gradients potentially have the largest influence. In this research, commercial ion exchange membranes (FAS and FKS, FUMATECH, Germany) are used for the investigation of temperature gradients in the limiting current regime. In contrast to the Ohmic regime, we find that heating the diluted stream increases the current obtained (at a constant applied potential) when compared to heating the concentrate stream in systems containing monovalent KCl and NaCl solutions. For mixtures of mono- and divalent ions, the temperature gradient has a larger influence on the selectivity of the separation. If the desalinated stream is heated, divalent Mg2+ ions show a higher transport than the monovalent K+ and Na+ ions. This is due to the enhanced competitive transport of the mono- and divalent ions under the application of a temperature gradient. These results show the potential application and relevance of temperature gradients to enhance the selective separation of mono- and divalent ions
Climatescan.nl: the development of a web-based map application to encourage knowledge-sharing of climate-proofing and urban resilient projects
Over recent years, there has been an explosion in the number and diversity of projects undertaken to address urban resilience and climate proofing. Sharing the knowledge gained from these projects demands increasingly innovative and accessible methods. This paper details the outcomes of one such initiative: an interactive web-based map application that provides an entry point to gain detailed information of various ‘blue-green’ projects. The climatescan.nl has proven to be a successful tool in several international workshops, not only for field-based practitioners but also for those involved in teaching and research. Further upscaling is needed however if the full potential of such an application is to be achieved
