Probing the provenance of archaeological glaze colorants: Polychrome faunal reliefs of the Ishtar Gate and the Processional Way of Babylon
The polychrome glazes from the Processional Way and the Ishtar Gate of Babylon are among the best preserved from antiquity. Yet, little is known about the logistical choices involved in
their production. Variations in isotope ratios can be useful for complementing an archaeological investigation of potential geological sources of raw materials. Consistent with archaeological
evidence and ancient texts on trade in metals, Turkish ore deposits are thus tentatively proposed as possible sources of the metal oxide colorants used for the investigated polychrome glazes of three Neo-Babylonian faunal reliefs that are now part of the collection of the Ny Carlsberg Glyptotek, Copenhagen
Dynamics of finite-sized light spheres in turbulence
We report experimental results on the Lagrangian dynamics of finite-size light particles in turbulence. Using an orthogonal camera setup and 3D particle tracking, we study the velocity and acceleration statistics of rigid light spheres in a water tunnel with nearly homogeneous and isotropic turbulence. The Reynolds number (ReY) is varied from 180 to 300, and the study covers a range of size ratios (4 < D/η < 16) for marginally light spheres. We find that the normalised acceleration PDF decreases in intermittency with increasing size ratio - in qualitative agreement with the predictions of the Faxén corrected model. We also present preliminary results on the rotational dynamics of large light spheres in turbulence
INVESTIGATING THE PROVENANCE OF EGYPTIAN BLUE PIGMENTS IN ANCIENT ROMAN POLYCHROMY
Egyptian blue is a copper-based blue pigment that was widely used across the Mediterranean from ca. 3300 BC up to late antiquity and even later. For this case study, we analyzed the provenance of Egyptian blue from a Campana relief from the collection of the Ny Carlsberg Glyptotek, Denmark. Campana reliefs are terracotta plaques, which were named after the Italian collector Gampietro Campana, who published the first collection in 1851. These mould-made plaques were used as ornaments in central Italy from ca. 60 BC to 50 AD – a time when Egyptian blue production is attested at several sites in the Bay of Naples, Italy. The provenance of copper raw materials that were used for producing this pigment could provide clues about the distribution of production centers and trade contacts. A previous investigation of the provenance of a single bulk Egyptian blue sample of this artefact by Rodler et al. (2017) indicated a possible long-distance transport of (Iberian) copper ore or mixing of distant (Iberian) and Italian copper. Our new data are based on the lead isotope analysis of four individual Egyptian blue samples. The refined sampling resolution emphasizes the Italian South-Eastern Alps as the most likely source area of copper raw materials. This copper could have been processed in local Egyptian blue production workshops or brought to the contemporary Egyptian blue production hub in the Bay of Naples and transported from there to the workshop where the artefact was painted

What is culturally appropriate food consumption? A systematic literature review exploring six conceptual themes and their implications for sustainable food system transformation
There is increasing recognition that sustainable diets need to be ‘culturally appropriate’. In relation to food consumption, however, it is often unclear what cultural appropriateness–or related terms, such as cultural or social acceptability–actually means. Often these terms go undefined, and where definitions are present, they vary widely. Based on a systematic literature review this paper explores how cultural appropriateness of food consumption is conceptualised across different research literatures, identifying six main themes in how cultural appropriateness is understood and applied. The paper then critically analyses these themes in relation to sustainable food system transformation. We explore how the themes conceptualise change, finding that cultural appropriateness is viewed in two main ways: either as a relatively static obstacle to be overcome, or as a dynamic and negotiated process. Both perspectives, we argue, entail different scientific, practical and political effects. Each perspective offers particular affordances for understanding and governing sustainable food system transition, although between perspectives there is likely to be a trade-off between theoretical sophistication and practical operationalizability. Based on this analysis we argue that researchers, policymakers and practitioners should be explicit about their commitment to a particular understanding of cultural appropriateness, as this will have implications for scientific and societal applications of their work. This is particularly the case, we suggest, in relation to the transdisciplinary collaborations necessary to effectively address the ‘wicked problem’ of food system sustainability. We conclude by offering a tentative general definition of cultural appropriateness as it relates to food consumption.QC 20240828</p

How to support Gen-Y consumers to start investing sustainably
Investing has become a hot topic among the younger generation since the Covid-19 crisis. However, much of its potential is still unused, as seen in a big group of the younger generation which is positive to start but procrastinates this decision. While this younger generation would like to make a positive impact with their money on the environment of the planet earth, the existing investing propositions aren’t helping them with that sustainable mission. In this thesis, I researched how Rabobank can help this group of young non-investors start investing, but with a sustainable focus. Creating a win-win situation for the non-investor who gets motivated to start investing consciously while at the same time helping them to fulfil their sustainable ambitions.To access the showcase use the following link: https://xd.adobe.com/view/1adcd6dd-4439-42e3-99e2-accc30bcbe44-4f8f/?fullscreenStrategic Product Desig
A Monte Carlo-based treatment planning tool for proton therapy
In the field of radiotherapy, Monte Carlo (MC) particle transport calculations are recognized for their superior accuracy in predicting dose and fluence distributions in patient geometries compared to analytical algorithms which are generally used for treatment planning due to their shorter execution times. In this work, a newly developed MC-based treatment planning (MCTP) tool for proton therapy is proposed to support treatment planning studies and research applications. It allows for single-field and simultaneous multiple-field optimization in realistic treatment scenarios and is based on the MC code FLUKA. Relative biological effectiveness (RBE)-weighted dose is optimized either with the common approach using a constant RBE of 1.1 or using a variable RBE according to radiobiological input tables. A validated reimplementation of the local effect model was used in this work to generate radiobiological input tables. Examples of treatment plans in water phantoms and in patient-CT geometries together with an experimental dosimetric validation of the plans are presented for clinical treatment parameters as used at the Italian National Center for Oncological Hadron Therapy. To conclude, a versatile MCTP tool for proton therapy was developed and validated for realistic patient treatment scenarios against dosimetric measurements and commercial analytical TP calculations. It is aimed to be used in future for research and to support treatment planning at state-of-the-art ion beam therapy facilities. © 2013 Institute of Physics and Engineering in Medicine
