No full textReference Organisms in Materials Science: Why and How?
No full textMaterials are subject to environmental constraints that include biological, chemical and physical factors. To gain confidence about durability and long-term performance of any material, environmental resistance testing procedures have to be amended with modern simulation procedures that include biological components. In fact, any environmentally exposed surface at temperatures lower than 121 °C will be home to microbial growth, even at high salt concentrations, extreme pH, environmental pollution, low water potential, and intense irradiation – everywhere where water is liquid and available. As a consequence, complex microbial ecosystems called biofilms are self-sufficient and found on almost all solid-air-water interfaces. Obviously, environmental changes perturb biofilm development but over a number of seasons, these changes result in relatively stable microbial communities peculiar and adapted to a particular niche and material. Certain microbial settlers are indicative of, and in a real sense mark, a particular biofilm and can, thus, be considered as “reference organisms”. Characteristic reference organisms’ peculiar to specific material-inhabiting communities can be isolated, identified, characterised and used in standard test procedures as well as research into materials science (materials improvement). In this presentation classical microbiological, genetic and molecular methods for studying reference organisms and their roles in materials deterioration will be presented. We will present a set of different reference organisms that are currently in focus of our research and testing development
The birth and early years of INA, the International Neurotoxicology Association
No full textAbstractThe International Neurotoxicology Association (INA) is a scientific society whose members have interest and expertise in the discipline of neurotoxicology. The idea of forming INA was born in 1984, as a follow-up to a NATO-sponsored meeting on Toxicology of the Nervous System. INA held its first meeting in the Netherlands in 1987 and has had continuous meetings every other year since then. INA is registered as a scientific society in the Netherlands, and is an affiliated society of IUTOX. This paper presents a personal account of the events that led to the birth of INA, and of the first fifteen years of this association
Biological durability and moisture dynamics of Dawn redwood (<i>Metasequoia glyptostroboides</i>) and Port Orford cedar (<i>Chamaecyparis lawsoniana</i>)
No full textNumerous non-native tree species are given attention with respect to the reforestation of calamity areas in Europe. Among them, several species may form durable wood which can be used for outdoor applications, but differences in wood durability are expected between original and European growth sites. This study aimed at examining the biological durability against wood-destroying fungi and water permeability of German-grown Dawn redwood (Metasequoia glyptostroboides) and Port Orford cedar (Chamaecyparis lawsoniana). The heartwood of both wood species was assigned to durability class 4 (DC 4, less durable) in soil contact and DC 1–4 (very to less durable) against wood-destroying basidiomycetes. However, according to the Meyer-Veltrup model, their material resistance dose was notably higher compared to the reference species Norway spruce (Picea abies), and the resulting service life of above ground structures should be a multiple of the reference.Bundesministerium für Ernährung und Landwirtschaft http://dx.doi.org/10.13039/50110000590

No full textIna Söllner was one of Schulz’s young sitters. As an adult person, she discovered in her autograph book a portrait of her mother, Ina, made by Schulz. The drawing called The King of Frogs [Żabi król] and a dedication referring to her mother sitting provoke the author to analyze her family connections with Schulz. Even though she does not remember her meeting with the artist, she reconstructs Schulz’s place in her biography and the circumstances under which they might have met
Pioneering Doktormutter Remembering Ina-Maria Greverus
No full textThe author reconsiders German scholar Ina-Maria Greverus as a committed feminist supporter of female doctoral students and early career academics. Greverus acted as an innovator especially in the realms of anthropology and aesthetics, and initiated a new international dialogue forum with the Anthropological Journal or European Cultures, which she founded in 1990 together with Christian Giordano.</p

Evaluation and optimization of seal behaviour through solid contamination of heat‐sealed films
No full text© 2019 The Authors. Packaging Technology and Science Published by John Wiley & Sons Ltd A method is presented to apply solid powder/granulate contamination (ground coffee and blood powder) in between the heat conductive seals of flexible packaging materials. A response surface method is tested and validated to optimize seal strength of heat conductive sealing with and without solid contamination. In this study, a maximal seal strength is defined as optimal. Using these methods, three typical packaging films with varying seal layer composition (metallocene linear low-density polyethylene (LLDPE), plastomer, and sodium ionomer) are maximized towards contaminated seal strength. Contamination caused a decrease in seal strength and narrowed down the process window (seal temperature and time combinations) in which at least 90% of the maximal strength is obtained. The influence of seal layer composition on the clean and solid (ground coffee and blood powder) contaminated seal performance (seal strength, process window, and leak tightness) was evaluated. The film with the plastomer-based seal layer outperformed the other films with respect to the width of the process window. It also reached a higher seal strength and a higher amount of leak tight seals (evaluated with the dye penetration test) after optimization. The hot tack test was evaluated as predictive test for the contaminated seal strength. The results of this study do not support an indicative relationship.sponsorship: German Federal Ministry for Economic Affairs and Energy, Grant/Award Number: 172 EBR; Agentschap Innoveren & Ondernemen, Grant/Award Number: 150817 (German Federal Ministry for Economic Affairs and Energy|172 EBR, Agentschap Innoveren Ondernemen|150817)status: Publishe
