Gefahrstoffliste Bundeswehr. Analyse der chemischen Wirkung von Versorgungsartikeln

In einer netzwerkfaehigen, benutzerfreundlichen, menuegesteuerten Datenbank, die auf einem Personalcomputer (Betriebssystem MS-DOS) lauffaehig ist, werden Informationen zu Betriebsschutz (Arbeitssicherheit), Umweltschutz (einschl Abfallentsorgung) sowie Transport, Lagerung und Erste Hilfe gespeichert. Insbesondere werden Stoffeigenschaften, Sicherheitsmassnahmen fuer den Umgang und gesetzlich vorgeschriebene Kennzeichnungen angegeben. Diese Angaben beziehen sich zum einen auf reine Chemikalien und zum anderen auf Versorgungsartikel (Produkte, Zubereitungen) der Bundeswehr (zB Reinigungsmittel, Klebstoffe, Lacke etc ). Die Liste der Gefahrstoffe ermoeglicht es jeder Dienststelle, Betriebsanweisungen nach Paragraph 20 der Gefahrstoffverordnung (GefStoffV) zu erstellen. Die GefStoffLBw enthaelt derzeit Daten zu ca 900 reinen Stoffen und ca 2000 Versorgungsartikeln.

Between Path Dependence and Path Creation: The Impact of Farmers' Behavior and Policies on Structural Change in Agriculture

Farm structures are often characterized by regional heterogeneity, agglomeration effects, sub-optimal farm sizes and income disparities. The main objective of this study is to analyze whether this is a result of path dependent structural change, what the determinants of path dependence are, and how it may be overcome. The focus is on the German dairy sector which has been highly regulated and subsidized in the past and faces severe structural deficits. The future of this sector in the process of an ongoing liberalization will be analyzed by applying theoretical concepts of path dependence and path breaking. In these regards, key issues are the actual situation, technological and market trends as well as agricultural policies. The methodology will be based on a participative use of the agent-based model AgriPoliS and participatory laboratory experiments. On the one hand, AgriPoliS will be tested as a tool for stakeholder oriented analysis of mechanisms, trends and policy effects. This part aims to analyze whether and how path dependence of structural change can be overcome on a sector level. In a second part, AgriPoliS will be extended such that human players (farmers, students) can take over the role of agents in the model. This part aims to compare human agents with computer agents in order to overcome single farm path dependence.

Schwerpunktprogramm (SPP) 527: Bereich Infrastruktur - International Ocean Discovery Program, Teilprojekt: Seismische Voruntersuchungen für eine IODP Bohrung auf dem Kapverden Plateau

Hauptfragestellungen des IODP-Vorschlags 'Cenozoic climate, productivity, and sediment transport at the NW African continental margin' sind: i) das NW-Afrikanische Klima in einer wärmeren Welt und ii) die Reaktion hochproduktiver Ökosysteme auf andere Klimabedingungen als heute. Dazu sollen Sedimentkerne in sechs Gebieten vor NW-Afrika erbohrt werden. Eine zentrale Lokation für die Arbeiten liegt auf dem Kapverden Plateau in der Nähe der ODP-Bohrung 659. Für dieses Gebiet existieren jedoch keine modernen hochauflösenden seismischen Daten. Solche Daten werden im Rahmen der Meteor-Ausfahrt M155 im Zeitraum vom 26. Mai bis 30. Juni 2019 gesammelt. Hauptziel dieses DFG-Antrags ist die Bearbeitung und Interpretation der neuen seismischen Daten, um die Sedimente des Kapverden Plateaus seismisch-stratigraphisch einzuordnen. Die seismischen Untersuchungen zielen darauf ab, eine Lokation zu identifizieren, an dem das Plio-Pleistozän dünner und das Miozän mächtiger ist als in der ODP-Bohrung 659. Damit wäre es möglich mittels APC-XCB tiefer in das Miozän zu bohren, was von entscheidender Bedeutung für die Gewinnung von qualitativ hochwertigen Kernen für Paläoklimauntersuchungen ist.

Schwerpunktprogramm (SPP) 1315: Biogeochemische Grenzflächen in Böden; Biogeochemical Interfaces in Soil, Imaging and image simulation of organic target compound migration between different biogeochemical interfaces of a soil horizon using positron emission tomography and the lattice Boltzmann equation approach

We propose to use positron emission tomography (PET) for imaging of tracer migration in a soil horizon, to be coupled with image simulation using the lattice Boltzmann equation (LBE) modeling approach. PET enables direct visualization of inert KF or KBr solute migration at the soil horizon scale, but also reactive halogenated organic target (2,4-D and MCPA) compound migration down to nM concentrations once radiolabelling with 18F or 76Br marker is achieved. Retardation at biogeochemical interfaces with different sorption properties will thus be imaged in-situ. Theoretical image simulation for process verification will be enabled by introducing a multi-grid approach and additional kinetic boundary conditions in the parallelized LBE solver. As a boundary condition for the latter, the real pore scale and distribution of biogeochemical interfaces will be derived by X-ray computer-tomography (XCT) down to 300 nm spatial voxel resolution. The aim is to produce by both approaches velocity field movies due to heterogeneous biogeochemical retardation of the target compounds with high resolution in both the spatial and temporal scale (4D).

Palaeo-Evo-Devo of Malacostraca - a key to the evolutionary history of 'higher' crustaceans

In my project I aim at a better understanding of the evolution of malacostracan crustaceans, which includes very different groups such as mantis shrimps, krill and lobsters. Previous studies on Malacostraca, on extant as well as on fossil representatives, focussed on adult morphology.In contrast to such approaches, I will apply a Palaeo-Evo-Devo approach to shed new light on the evolution of Malacostraca. Palaeo-Evo-Devo uses data of different developmental stages of fossil malacostracan crustaceans, such as larval and juvenile stages. With this approach I aim at bridging morphological gaps between the different diverse lineages of modern malacostracans by providing new insights into the character evolution in these lineages.An extensive number of larval and juvenile malacostracans is present in the fossil record, but which have only scarcely been studied. The backbone of this project will be on malacostracans from the Solnhofen Lithographic Limestones (ca. 150 million years old), which are especially well preserved and exhibit minute details. During previous studies, I developed new documentation methods for tiny fossils from these deposits, e.g., fluorescence composite microscopy, and also discovered the first fossil mantis shrimp larvae. For malcostracan groups that do not occur in Solnhofen, I will investigate fossils from other lagerstätten, e.g., Mazon Creek and Bear Gulch (USA), or Montceaules- Mines and La-Voulte-sur-Rhône (France). The main groups in focus are mantis shrimps and certain other shrimps (e.g., mysids, caridoids), as well as the bottom-living ten-footed crustaceans (reptantians). Examples for studied structures are leg details, including the feeding apparatus, but also eyes. The results will contribute to the reconstruction of 3D computer models.The data collected in this project will be used for evaluating the relationships within Malacostraca, but mainly for providing plausible evolutionary scenarios, how the modern malacostracan diversity evolved. With the Palaeo-Evo-Devo approach, I am also able to detect shifts in developmental timing, called heterochrony, which is interpreted as one of the major driving forces of evolution. Finally, the reconstructed evolutionary patterns can be compared between the different lineages for convergencies. These comparisons might help to explain the convergent adaptation to similar ecological niches in different malacostracan groups, e.g., life in the deep sea, life on the sea bottom, evolution of metamorphosis or of predatory larvae.As the project requires the investigation of a large number of specimens in different groups, I will assign distinct sub-projects to three doctoral researchers. The results of this project will not only be published in peer-reviewed journals, but will also be presented to the non-scientific public, e.g., during fossil fairs or museum exhibitions with 3D models engraved in glass blocks.
