Leistungen der ökologischen Landwirtschaft zur Vermeidung von Stoffeinträgen in das Grund- und Oberflächenwasser im Vergleich zu konventioneller Bewirtschaftung

Stoffeinträge aus der Landwirtschaft in das Grund- und Oberflächenwasser stellen ein hohes Umweltrisiko dar. In einer systematischen Literaturübersicht wurden ökologische und konventionelle Landwirtschaft hinsichtlich der jeweiligen Belastungen des Grund- und Oberflächenwassers im Vergleich untersucht. Insgesamt wurden 96 Vergleichsstudien mit 308 Vergleichpaaren evaluiert. 63% der Vergleichpaare zeigen Vorteile des ökologischen Landbaus in Bezug auf Nitratausträge, genauso 90% der Vergleichspaare in Bezug auf Pestizidbelastungen. Im Schnitt (Median) können unter ökologischer Bewirtsvchaftung 28% weniger Nitratauswaschungen festgestellt werden als in der konventionellen Landwirtschaft, zudem werden keine Pestizide und vermutlich auch weniger Tierarzneimittel in das Grund- und Oberflächenwasser ausgewaschen. Hinsichtlich des Austrags von Phosphor ist die Datenlage unklar. Das System der ökologischen Landwirtschaft zeigt ein hohes Potential im Schutz von Grund- und Oberflächenwasser

The UnCoVerCPS Verification Approach to Automated Driving

There are several benefits for bringing automated vehicles to the road: Possible reduction of traffic accidents, improvement of work life balance and social inclusion of aged or disabled persons, to name just a few. A significant challenge is the validation and verification of automated driving. Classical offline verification approaches require enumeration and discretization of all relevant state variables in all possible driving situations, which results in a state space explosion. A promising approach is the use of online verification techniques pursued in UnCoVerCPS . The methods developed in UnCoVerCPS are generally applicable to many safety critical, cyber physical systems. As a specific use case, we investigate a system which facilitates safe interactions of automated vehicles, leveraging a formal proof on a validated model. By exchanging and negotiating verified maneuver plans, the freedom of collisions and safe operation in general can be guaranteed for the situation at hand. The system design is tailored to make the complete system amenable to verification. An overview is given in fig. 1: The system is decomposed into three layers (green boxes), where each is fulfilling a contract, which guarantees correct operation under specific types of uncertainties. The combination of the three layers enables safe operation under disturbances, input- and parameter uncertainties, non-determinisms of the communication channel as well as nondeterminism of the decisions of cooperation partners. On the lowest layer is the physical vehicle, modeled as a set of nonlinear differential equations with bounded uncertain parameters and disturbances. The second layer is realized by a classical discrete time trajectory tracking controller “TTC”, which stabilizes the vehicle around a given set trajectory, while operating on noisy measurement data. Vehicle model and trajectory tracking controller are considered as a closed loop system by an offline analysis shown at the bottom of fig. 1 (steps 1.Modeling – 6.Verification), which computes bounds on state evolution of the physical system (rather than the model), for a finite set of atomic actions (maneuver database – “MDB”). During online execution, several maneuver planners “MP” assemble the guarantees of the pre-verified atomic actions and use conservative bounds on the environment perception to generate provably safe maneuvers. A timed-automaton (cooperative driving controller – “CDC”) controls negotiation of safe, cooperative maneuvers with other vehicles. It guarantees safe operation even under the assumption of message loss and delays, as well as non-deterministic planning times. This is achieved by prudent switching between cooperative, individual and failsafe maneuvers. In this paper we give an overview of the offline design process, which, besides classical development steps, involves (fig.1, step 4.) sampling possible vehicle actions, (5.) generating a reliable model by testing conformance between the actual physical system and a model with bounded uncertainties and (6.) verifying time in-variant constraints and admissible execution orders of the vehicle actions. Furthermore we focus on the online execution, where maneuver planners and the cooperative driving controller guarantee compliance to time varying constraints. Where “monolithic” verification schemes are hampered by the curse of dimensionality, our modular and layered approach of verifying lower-level, closed-loop subsystems offline and higher-level decision modules online provides formal safety guarantees for the overall system in a feasible manner

X20CoCrWMo10-9//Co3O4: a Metal-Ceramic Composite with Unique Efficiency Values for Water-Splitting in Neutral Regime

Water splitting allows the storage of solar energy into chemical bonds (H2+O2) and will help to implement the urgently needed replacement of limited available fossil fuels. Particularly in neutral environment electrochemically initiated water splitting suffers from low efficiency due to high overpotentials caused by the anode. Electro-activation of X20CoCrWMo10-9, a Co-based tool steel resulted in a new composite material (X20CoCrWMo10-9//Co3O4) that catalyzes the anode half-cell reaction of water electrolysis with a so far unequalled effectiveness. The current density achieved with this new anode in pH 7 corrected 0.1 M phosphate buffer is over a wide range of overpotentials around 10 times higher compared to recently developed, up-to-date electrocatalysts and represents the benchmark performance advanced catalysts show in regimes that support water splitting significantly better than pH 7 medium. X20CoCrWMo10-9//Co3O4 exhibited electrocatalytic properties not only at pH 7, but also at pH 13, which is much superior to the ones of IrO2-RuO2, single-phase Co3O4- or Fe/Ni- based catalysts. Both XPS and FT-IR experiments unmasked Co3O4 as the dominating compound on the surface of the X20CoCrWMo10-9//Co3O4 composite. Upon a comprehensive dual beam FIB-SEM (focused ion beam-scanning electron microscopy) study we could show that the new composite does not exhibit a classical substrate-layer structure due to the intrinsic formation of the Co-enriched outer zone. This structural particularity is basically responsible for the outstanding electrocatalytic OER performance

Smoothed Particle Hydrodynamics and Magnetohydrodynamics

This paper presents an overview and introduction to Smoothed Particle Hydrodynamics and Magnetohydrodynamics in theory and in practice. Firstly, we give a basic grounding in the fundamentals of SPH, showing how the equations of motion and energy can be self-consistently derived from the density estimate. We then show how to interpret these equations using the basic SPH interpolation formulae and highlight the subtle difference in approach between SPH and other particle methods. In doing so, we also critique several `urban myths' regarding SPH, in particular the idea that one can simply increase the `neighbour number' more slowly than the total number of particles in order to obtain convergence. We also discuss the origin of numerical instabilities such as the pairing and tensile instabilities. Finally, we give practical advice on how to resolve three of the main issues with SPMHD: removing the tensile instability, formulating dissipative terms for MHD shocks and enforcing the divergence constraint on the particles, and we give the current status of developments in this area. Accompanying the paper is the first public release of the NDSPMHD SPH code, a 1, 2 and 3 dimensional code designed as a testbed for SPH/SPMHD algorithms that can be used to test many of the ideas and used to run all of the numerical examples contained in the paper.Comment: 44 pages, 14 figures, accepted to special edition of J. Comp. Phys. on "Computational Plasma Physics". The ndspmhd code is available for download from http://users.monash.edu.au/~dprice/ndspmhd

Steigerung der Wertschöpfung ökologisch angebauter Marktfrüchte durch Optimierung des Managements der Bodenfruchtbarkeit

Das interdisziplinäre Bodenfruchtbarkeitsprojekt beschäftigte sich in vier Versuchs- und fünf Projektjahren mit den Zusammenhängen zwischen dem Anbau von Körnerleguminosen und Bodenfruchtbarkeit, insbesondere auf viehschwachen bzw. viehlosen Biobetrieben. In Erhebungen auf 32 Praxisbetrieben konnten bislang allenfalls vermutete Zusammenhänge wie z. B. die Zunahme des Unkrautdeckungsgrades mit zunehmendem Humusgehalt bestätigt werden. Die Ergebnisse deuten auch darauf hin, dass z. B. die Anbauabstände im Erbsenanbau im Vergleich zu praxisüblichen Empfehlungen vergrößert werden müssen, daneben ergaben sich auch interessante neue Anknüpfungspunkte. Hinsichtlich der Leguminosengesundheit ermöglicht die neu entwickelte Differenzialdiagnose, die Ursache für ggf. auftretende „Leguminosenmüdigkeit“ einzugrenzen bzw. Praxisschläge vor dem Anbau auf Krankheitsrisiken zu testen. Im Projekt konnte außerdem gezeigt werden, dass Grüngutkomposte die Wurzelgesundheit von Erbsen deutlich verbessern können. Es wurden darüber hinaus verschiedene Methoden zur Kompostapplikation zu Körnerleguminosen geprüft und für den Praxiseinsatz optimiert. Neben Grüngutkomposten spielt auch Grünguthäcksel eine wichtige Rolle bei der Nährstoffversorgung von Leguminosen. Oberflächlich leicht eingearbeiteter Grünguthäcksel ist in der Lage, das Wachstum der Kulturpflanzen sowohl durch eine unkrautunterdrückende Wirkung als auch durch Schutz vor Verschlämmung sowie erhöhte Wasserinfiltrationsraten zu verbessern. Die Ergebnisse zum Landtechnikeinsatz zeigen, dass schon geringe Belastungen zu Bodenverdichtungen und damit zu Ertragsrückgängen in Erbsen führen, weshalb Maßnahmen zu Reduzierung des Bodendrucks essenziell sind. Hinsichtlich der beikrautunterdrückenden Wirkung des Gemengeanbaus von Erbsen in Kombination mit Hafer konnte gezeigt werden, dass der Gemengeanbau das erhöhte Beikrautaufkommen bei flachwendender Bodenbearbeitung erfolgreich ausgleichen kann und hinsichtlich der Ertragssicherheit Vorteile mit sich bringt. Nicht zuletzt machte das Projekt auf die Vorteile und Potenziale des Wintererbsenanbaus aufmerksam. Über einen fortlaufenden Wissenstransfer war das Projekt von Beginn an in der landwirtschaftlichen Praxis präsent
