On the Promoting Effects of Te and Nb in the Activity and Selectivity of M1 MoV-Oxides for Ethane Oxidative Dehydrogenation
Authors: Melzer Daniel , Mestl Gerhard , Wanninger Klaus , Jentys Andreas , Sanchez-Sanchez Maricruz , Lercher Johannes A. 
Published: July 2020

AbstractThe pathways of ethane oxidative dehydrogenation and total combustion have been elucidated for M1 phase type Mo–V oxide catalysts with different metal composition. The ethane oxidation mechanism is not affected by the presence of Te or Nb. Conversely, the selectivity is strongly affected by stoichiometry of M1 catalysts. This is attributed to the facile oxidation of ethene to COx upon formation of unselective VOx species in the absence of Te and Nb.

Published: July 2020

AbstractSimulation is a basic method to analyze water resources system and provide information for decision-making. In this study, a framework is presented that describes the basic elements in a water resource system and a modelling technique integrating conceptual simulation and rule control. To formulate the process of the water cycle and water exploitation with a mathematical model, the water system is described based on adjustable relevant rules and respective parameters with experiences and pragmatic demands in the framework. The rule set describes the principles required to design conceptual networks and control the concrete processes of movement and conversion of different water flows. Combined with object-oriented programming, different calculation functional modules are classified based on the characteristics of water source layers, and the processes that occur in the networks are realised in the computation. The influence of the South-to-North Water Diversion project on the Haihe River basin is analysed by the rule-based object-oriented water resource allocation simulation model. According to the simulation results, groundwater extraction will be reduced by 6,181 million m3. The relationship between water source replacement and water layer exchange in the Haihe River basin is analysed, and the feasibility of the model is verified. Based on the rule-based model, the user requirements can be taken into account conveniently, and the rules are flexible to adjust with experiences and real conditions. This model can be used to simulate complex water resource systems.
Environmental sustainable value in agriculture revisited: How does Common Agricultural Policy contribute to eco-efficiency?

Published: July 2020

AbstractThe conflict between capital-intensive agriculture, often called industrial agriculture, and sustainable farming is ongoing, and not because of Western European countries, where intensification is increasingly sustainable. It is caused by several million small farms in Central and Eastern Europe that must choose a long-term development path. This is also a dilemma for agricultural policy: Are small farms so environmentally friendly that they should play the role of ‘landscape guardians’ at the expense of public support and economic vegetation, or should they strive to improve productivity through investments? This study offers a methodological contribution to the value-based sustainability approach by computing indicators of environmental sustainable value (ESV). The authors have attempted to combine the value-oriented approach with frontier benchmarking. They then tested how the European Union Common Agricultural Policy (CAP) schemes contribute to ESV using a long-term panel of regionally representative farms from Farm Accountancy Data Network (FADN) with regard to factor endowments, for the years 2004–2017. The seminal within–between specification was employed to control the time variant and time invariant space heterogeneity of European regions. The main finding is that higher investment support is beneficial to ESV. Regarding factor endowment influence, there was a positive impact of the capital–labour ratio. Except the cross-sectional impact of environmental subsidies, the payments exert a negative effect on ESV.

Published: July 2020

AbstractSomatic embryogenesis has already been used for Norway spruce (Picea abies(L.) Karst) embling production on a laboratory scale, but automation is needed to increase efficiency and reduce costs. One option to scale up production is mass production in bioreactors. In a series of experiments, a pro-embryogenic mass was propagated using Plantform temporary immersion system bioreactors, and the effect of different aeration cycles, support pad materials, and post-maturation treatments (rinsing and desiccation) on the embryo yield and embling survival after 4 to 6 mo in a greenhouse was tested. Three genotypes were used to test each treatment. The best aeration frequency was 20 min every 4 h, while a lower or higher frequency did not generally improve embryo production. Filter paper on plastic netting was the best support pad material in terms of usability and embryo production (varying from 177 ± 20 to 696 ± 109 per g pro-embryogenic mass). The separation of the embryos from the undeveloped cell mass by rinsing with sterile water resulted in reduced survival of the emblings. Desiccation treatment on nested plates with the embryos on the inner plate with or without filter paper improved their survival. Bioreactors were laborious to prepare, load, and clean. Improvements in embryo production can be achieved by optimizing the process, but bioreactors based on the requirements of somatic embryogenesis are needed to enable their use in the mass production of Norway spruce emblings.
Advances in Microstructural Understanding of Wrought Aluminum Alloys

Published: July 2020

Abstract
Wrought aluminum alloys are an attractive option in the quest for lightweight, recyclable, structural materials. Modern wrought aluminum alloys depend on control of complex microstructures to obtain their properties. This requires an understanding of the coupling between alloy composition, processing, and microstructure. This paper summarizes recent work to understand microstructural evolution in such alloys, utilizing the advanced characterization techniques now available such as atom probe tomography, high-resolution electron microscopy, and synchrotron X-ray diffraction and scattering. New insights into precipitation processes, deformation behavior, and texture evolution are discussed. Recent progress in predicting microstructural evolution using computer modeling is also summarized.
Security of passenger transport in the Baltic Sea in the context of foreign terrorist fighters
Authors: Wardin Katarzyna 
Published: July 2020

AbstractThe Baltic Sea basin is one of the busiest areas in Europe in terms of the passenger transport and is considered as a domestic sea of the European Union, very important for the development and prosperity of all citizens. A high number of ferries connections along with exclusive cruise ships, visiting the Baltic countries, make the sea very busy. At the same time the security of lines of communications has become the highest priority, especially that a possibility of terrorist attacks still poses a serious threat. Although terrorism has been being fought intensively since 11th September, terrorist organizations such as Al-Qaeda or Islamic State of Iraq and the Levant, are still able to attack. The article considers the threat of organizing a terrorist attack posed by Foreign Terrorist Fighters returning home to the Baltic countries. Due to the fairly high number of Foreign Terrorist Fighters in some countries around the Baltic Sea, very intense passenger traffic in the area, and the appeals which have been proclaimed by Al-Qaeda and Islamic State leaders, there is a possibility of a terrorist attack occurrence in the near future. Cited facts lead to the conclusion that some precautions should be taken both in terms of technical and organizational measures to make passenger traffic secure.
The Role of Biomarkers in Cardio-Oncology
Authors: Ananthan Kajaluxy , Lyon Alexander R. 
Published: July 2020

AbstractIn the field of cardio-oncology, it is well recognised that despite the benefits of chemotherapy in treating and possibly curing cancer, it can cause catastrophic damage to bystander tissues resulting in a range of potentially of life-threatening cardiovascular toxicities, and leading to a number of damaging side effects including heart failure and myocardial infarction. Cardiotoxicity is responsible for significant morbidity and mortality in the long-term in oncology patients, specifically due to left ventricular dysfunction. There is increasing emphasis on the early use of biomarkers in order to detect the cardiotoxicity at a stage before it becomes irreversible. The most important markers of cardiac injury are cardiac troponin and natriuretic peptides, whilst markers of inflammation such as interleukin-6, C-reactive protein, myeloperoxidase, Galectin-3, growth differentiation factor-15 are under investigation for their use in detecting cardiotoxicity early. In addition, microRNAs, genome-wide association studies and proteomics are being studied as novel markers of cardiovascular injury or inflammation. The aim of this literature review is to discuss the evidence base behind the use of these biomarkers for the detection of cardiotoxicity.
Two patients with COVID-19 and a fever-induced Brugada-like electrocardiographic pattern
Authors: van de Poll S. W. E. , van der Werf C. 
Published: July 2020

AbstractFebrile states may unmask certain Brugada syndrome patients and precipitate ventricular arrhythmias. Here we describe two patients with COVID-19 who developed a fever-induced type 1 Brugada electrocardiographic pattern. Both patients did not show any ventricular arrhythmias during admission. These and previously published cases suggest that the threshold to run an ECG should be low in febrile patients with suspected COVID-19, because these patients are potentially at risk for developing proarrhythmic complications.
Epidemics and food systems: what gets framed, gets done
Authors: Gillespie Stuart 
Published: July 2020

AbstractThis brief article aims to interrogate some widely used concepts in framing the interactions between disease epidemics, food systems and nutrition, with a particular focus on the COVID-19 crisis. How should we conceptualize vulnerability in such situations – both with regard to viral exposure and to subsequent nutrition-relevant impacts of epidemics and responses (including lockdowns)? Is it possible to simultaneously pursue strategies aimed at strengthening resilience and driving transformation (‘building back better’)? What type of framing and conceptualization can help illuminate entry points and options for responding effectively to interacting crises? In addressing these questions, it’s important to re-visit lessons from past attempts to address the impacts of epidemics on food and nutrition security.
Does Implementation of the Smart Growth Priority Affect Per Capita Income of EU countries?—Empirical Analysis for the Period 2000–2017
Authors: Młynarzewska-Borowiec Izabela 
Published: July 2020

AbstractSmart growth is one of the priorities of the Europe 2020 strategy, implemented by European Union member states since 2010. Developing economy based on knowledge, human capital and innovation, ipso facto, implementing the smart growth objectives, is theoretically justified and should stimulate growth processes in EU economies. The aim of this study is to examine the existence and nature of the relationship between the state of implementation of the smart growth targets in the new and old EU countries and their GDP per capita. The analysis for the period 2000–2017 indicated a varied degree of advancement of EU countries in implementing the smart growth targets. The assessment of the overall level of the smart growth targets’ implementation, expressed in the smart growth summary index calculated in this paper, leads to the conclusion that the new EU members, having a relatively lower level of initial implementation of the smart growth objectives, showed a much higher dynamic in this field than the old EU members. The surveys conducted with the use of econometric models confirmed that effective implementation of the smart growth targets resulting in a higher employment rate and improvement of the quality of human capital had a positive impact on GDP per capita in EU countries, especially in the new member states. The results indicate that investment in R&D did not automatically affect the level of GDP per capita of the analysed economies. This impact was spread over time and limited only to the countries where R&D expenditure was higher than 1.5% of GDP.

Published: July 2020

AbstractUse of biochar (B) and poultry manure (PM) as soil amendments can improve the productivity and sustainability of tropical agriculture. Our fieldwork is the first research on the agronomic use of B and PM for the growth of cocoyam in sandy soil of the humid tropics. In this study, the effects of B, PM and their mixture were investigated on soil properties, mineral and nutrient concentrations, growth, and corm and cormel yields of cocoyam during the 2017 and 2018 cropping seasons. The experiment consisted of 4 × 2 factorial combinations of B (0, 10, 20, and 30 Mg ha−1) and PM (0 and 7.5 Mg ha−1). In both years, the application of B and PM either alone or in combination improved soil physical and chemical properties, plant nutritional status, growth, and corm and cormel yields of cocoyam. The combination of 30 Mg ha−1 B and 7.5 Mg ha−1 PM (B30 + PM7.5) gave the highest corm and cormel yields of cocoyam. Pooled over the 2 years, application of B at 30 Mg ha−1 and PM at 7.5 Mg ha−1 (B30 + PM7.5) significantly increased corm yield of cocoyam by 47 and 66%, respectively, when compared with sole PM at 7.5 Mg ha−1 and B at 30 Mg ha−1. Lowest corm and cormel yields were obtained for the unmanure control. The combination of 30 Mg ha−1 B and 7.5 Mg ha−1 PM is recommended for soil fertility management and cocoyam production in the rainforest agroecology of SW Nigeria.
Multi-scale dynamics of magnetic flux tubes and inverse magnetic energy transfer
Authors: Zhou Muni , Loureiro Nuno F. , Uzdensky Dmitri A. 
Published: July 2020

We report on an analytical and numerical study of the dynamics of a three-dimensional array of identical magnetic flux tubes in the reduced-magnetohydrodynamic description of the plasma. We propose that the long-time evolution of this system is dictated by flux-tube mergers, and that such mergers are dynamically constrained by the conservation of the pertinent (ideal) invariants,viz.the magnetic potential and axial fluxes of each tube. We also propose that in the direction perpendicular to the merging plane, flux tubes evolve in a critically balanced fashion. These notions allow us to construct an analytical model for how quantities such as the magnetic energy and the energy-containing scale evolve as functions of time. Of particular importance is the conclusion that, like its two-dimensional counterpart, this system exhibits an inverse transfer of magnetic energy that terminates only at the system scale. We perform direct numerical simulations that confirm these predictions and reveal other interesting aspects of the evolution of the system. We find, for example, that the early time evolution is characterized by a sharp decay of the initial magnetic energy, which we attribute to the ubiquitous formation of current sheets. We also show that a quantitatively similar inverse transfer of magnetic energy is observed when the initial condition is a random, small-scale magnetic seed field.
From Sustainable Development Goals to Basic Development Goals
Authors: Reinert Kenneth A. 
Published: July 2020

AbstractThe Sustainable Development Goals have attracted both defenders and critics. Composed of seventeen goals and 169 targets, the overly broad scope of the SDGs raises the question of whether there are priorities that need to be set within them. This essay considers the SDGs from the perspective of a “basic goods approach” to development policy, which takes a needs-based and basic-subsistence-rights view on policy priorities. It focuses on a subset of SDGs that directly address the provision of nutritious food, clean water, sanitation, health services, education services, and human security services. In doing so, it proposes a set of seven “basic development goals” and ten associated targets. It argues that this more focused approach can better protect basic rights, more effectively contribute to progress on human wellbeing, and make accountability more likely.
Limited Force and the Return of Reprisals in the Law of Armed Conflict
Authors: Heinze Eric A. , Neilsen Rhiannon 
Published: July 2020

AbstractArmed reprisals are the limited use of military force in response to unlawful actions perpetrated against states. Historically, reprisals provided a military remedy for states that had been wronged (often violently) by another state without having to resort to all-out war in order to counter or deter such wrongful actions. While reprisals are broadly believed to have been outlawed by the UN Charter, states continue to routinely undertake such self-help measures. As part of the roundtable, “The Ethics of Limited Strikes,” this essay examines the doctrine of armed reprisals in light of recent instances of states using force “short of war” in this manner. We argue that the ban on reprisals has been largely ignored by states, and that recent attempts to apply the laws of armed conflict to the cyber domain (such as the Tallinn Manual) are further weakening this prohibition. We conclude that this is a potentially dangerous development that lowers the bar for resorting to military force, risking escalation and thereby further destabilizing the international system.
A Matter of Balance: A French Perspective on Limited Strikes
Authors: Jeangène Vilmer Jean-Baptiste 
Published: July 2020

AbstractWhat are the philosophical arguments justifying limited strikes? This essay, as part of the roundtable “The Ethics of Limited Strikes,” adopts a French perspective both because France is, along with the United States and the United Kingdom, one of the states that launched such limited strikes in recent years, and because it developed a limited warfare ethos. There is something specific about such an ethos that makes it particularly receptive to thejus ad vimframework and, therefore, to the issue of limited strikes. This essay also builds on the case of the use (or threat) of limited force in Syria as a response to the country's use of chemical weapons between 2013 and 2018. Presented as a way to “punish” the Syrian regime as much as to “deter” it from using chemical weapons again, these limited strikes are a good illustration of the traditional retributive/preventive dichotomy of penal philosophy. I argue that the moral justification of those strikes should be guided by a consequentialist ethic, preventive rather than retributive. From a consequentialist perspective, limited strikes are justified when they “work”—that is, when they have a deterrent/compellent effect. For that to happen, they need to be credible and imply the potential of an escalation; the challenge being to keep the escalation under control. Carrying the risk of inefficacy at one end of the spectrum and of escalation at the other, limited strikes are indeed a matter of balance.

AbstractWe report apatite fission-track and 10Be terrestrial cosmogenic nuclide (TCN) dating of 14 moraine boulders originating from inland Terre Adélie, East Antarctica. These data show cooling of the Proterozoic Terre Adélie craton at < ~120°C between 350 and 300 Ma, suggesting > 4 km temperate glacial erosion during the Late Palaeozoic Ice Age, followed by nearly null Mesozoic erosion and low glacial erosion (< 2 km) in the Cenozoic. Based on glacial flux maps, the origin of the boulders may be located ~400 km upstream. Preliminary TCN (10Be) datings of moraine boulders cluster within the last 30 ka. Cosmogenic ages from the Lacroix Nunatak suggest a main deglaciation after the Younger Dryas at c. 10 ka, while those of Cap Prud'homme mostly cluster at 0.6 ka, in agreement with an exhumation of boulders during the Little Ice Age.
Genetic markers associated with seed longevity and vitamin E in diverse Aus rice varieties
Authors: Lee Jae-Sung , Kwak Jieun , Hay Fiona R. 
Published: July 2020

AbstractVitamin E is known to scavenge lipid peroxy radicals and has a purported role in preventing seed deterioration during storage. In our previous studies using 20 rice varieties from different variety groups, the specific ratio of vitamin E homologues rather than total vitamin E content was associated with seed longevity. To validate this result, we extended the experiment to a rice panel composed of 185 Aus (semi-wild rice) varieties. Seed longevity values were determined through storage experiments at 45°C and 10.9% seed moisture content (MC). Eight types of vitamin E homologues (α-, β-, γ- and δ-tocopherol/tocotrienol) were quantified by ultra-performance liquid chromatography. The theoretical initial viability in NED, Ki, was positively correlated with γ- and δ-tocopherols and negatively correlated with α-tocotrienol. The time for viability to fall to 50% during storage at elevated temperature and relative humidity, p50, was positively correlated with δ-tocopherol. The harvest MC was negatively correlated with all seed longevity traits. Taking this factor into account in a genome-wide association (GWA) analysis, we were able to correct false positives. A consistent major peak on chromosome 4 associated with −σ−1 was detected with a mixed linear analysis. Based on rice genome annotation and gene network ontology databases, we suggest that RNA modification, oxidation–reduction, protein–protein interactions and abscisic acid signal transduction play roles in seed longevity extension of Aus rice. Although major GWA regions were not overlapped across traits, three genetic markers, on chromosomes 1, 3 and 4, were associated with both δ-tocopherol and Ki and two markers on chromosome 1 and 8 were associated with both δ-tocopherol and p50.
