Chasing millimeters: design, navigation and state estimation for precise in-flight marking on ceilings
Authors: Lanegger Christian , Pantic Michael , Bähnemann Rik , Siegwart Roland , Ott Lionel 
Published: October 2023

AbstractPrecise markings for drilling and assembly are crucial, laborious construction tasks. Aerial robots with suitable end-effectors are capable of markings at the millimeter scale. However, so far, they have only been demonstrated under laboratory conditions where rigid state estimation and navigation assumptions do not impede robustness and accuracy. This paper presents a complete aerial layouting system capable of precise markings on-site under realistic conditions. We use a compliant actuated end-effector on an omnidirectional flying base. Combining a two-stage factor-graph state estimator with a Riemannian Motion Policy-based navigation stack, we avoid the need for a globally consistent state estimate and increase robustness. The policy-based navigation is structured into individual behaviors in different state spaces. Through a comprehensive study, we show that the system creates highly precise markings at a relative precision of 1.5 mm and a global accuracy of 5–6 mm and discuss the results in the context of future construction robotics.

AbstractThe grafting of stimuli-responsive polymers into medical devices to create functional materials has attracted the attention of scientific community. The capacity of these polymers to change its conformation reversibly as function of variables of the environment in which it is applied, is well taken into account to create drug delivery systems. Because cotton gauzes are materials of priority use in biomedical area, and they are susceptible to develop biofilm on its surface contaminating skin wounds. This work proposes the modification of cotton gauze with a dual stimuli-responsive copolymer, composed of two monomers such as methacrylic acid and N-isopropylacrylamide, through a grafting copolymerization induced by chemical initiator and gamma radiation. Experimental conditions were evaluated for each method. Grafting was verified by infrared spectroscopy (FTIR-ATR) and scanning electron microscopy as well as its thermal behavior was determined through thermogravimetric analysis. Critical pH was confirmed by potentiometric titrations finding a value of 4.7 for grafted cotton gauzes and their critical temperature ranging between 31 and 34 °C, which was determined by water uptake as function of temperature. The loading and release of norfloxacin were tested, finding that grafted gauzes exhibited affinity for this drug and it is released under simulated physiological conditions of temperature and pH. Norfloxacin-loaded gauzes show their efficiency inhibiting Escherichia coli and Staphylococcus aureus growth in a contaminated environment, at different pH values. This improvement of cotton gauzes can serve as barrier to avoid the formation of biofilm in surgical conditions and for wound healing.

Abstract
Natural wetlands are critically important to the lives and livelihoods of many people. Human activities result in the degradation of wetlands globally, and more so in developing countries prioritizing fast economic growth and development. With an increasing population in their immediate surroundings, wetlands in Wakiso District, Uganda, have become over-exploited to meet human needs. Policies, plans and projects have been put in place aiming at wetland conservation and restoration, but with limited stakeholder participation, have achieved limited success. Our research objective was to identify stakeholders, their perceptions, and understand the role these perceptions play in wetland conservation and restoration activities. To achieve these objectives, we used the ecosystem services concept within a qualitative, multi-site case study research approach. Findings show that stakeholders hold divergent perceptions on wetland ecosystem services, perceiving them as source of materials, fertile places for farming, cheap to buy and own, as well as being “God-given”. Furthermore, wetlands as habitats are perceived as not prioritized by central government. Implications for conservation and restoration vary with stakeholders advocating for (1) over-use, wise-use or not-use of wetlands and their resources, (2) educating and sensitization as well as (3) the implementation of the available laws and policies. This paper explores the findings and important implications for the conservation and restoration of wetlands in Wakiso District, Uganda.
Introduction of a new index to assess pavement functional condition

Published: October 2023

Abstract
For most countries, the construction of the road network is completed to a great extent. As a result, the road operators have focused on the management of the current road constructions. The pavement management systems have been the determinative answer to the above need finding the optimal and more efficient solution which minimizes the maintenance cost. In this context, the present paper aims at the development of an index that assesses sections of road networks based both on the pavement essential demands and surface characteristics. This project presents a model for the rating of highway sections taking into consideration criteria and sub-criteria related to the pavement function. The developed model has been formed based on the opinion of a group of experts. The technique of the fuzzy analytic hierarchy process (FAHP) has been used to mathematically analyze the above opinions and manipulate uncertainty and subjectivity. This method ends up by calculating the weights of significance which are the factors of the index equation. The index is composed in combination with the variables which have come up from the regular measurements of pavement characteristics assessing the pavement functional condition. The results are compared to those of the regular AHP highlighting the degree of influence by the uncertainty of experts’ judgments in some factors of the index. Furthermore, the suitability and ease in the fitting of the FAHP method are verified in pavement management problems. In this project data related to the checks on surface characteristics in the National Highway Network are displayed.
Zooplankton as an indicator of hydrological connectivity of the main channel and the floodplain in a large river system

Published: October 2023

AbstractThe connectivity of the river–floodplain system during floods plays a decisive role in organisms/matter contribution to the ecosystems of large lowland rivers. We hypothesized that the direction of water-level trends during flood was crucial for zooplankton release from the floodplain into the river channel. The seven-year study of zooplankton in the large plain Ob river suggest that at the inundated floodplain even a slight water level fall brings to plankton release from the floodplain into the river thus causing its abundance boom in the main channel. At water-level stabilization or rise, zooplankton communities of floodplain become isolated from the channel that ceases the recruits’ inflow from the floodplain and brings to a sharp drop in number of river zooplankton. Therefore, it is necessary to take into account dynamics trends (i.e., fall or rise) in river water level when assessing zooplankton density in large lowland rivers. The analysis of such trends should become the basis for predicting of river zooplankton abundance and assessing changes in feeding conditions of fish during the growing season.

AbstractThis work represents the shaping of alumina–zinc oxide (AZ) samples with the direct coagulation casting method. The effect of zinc oxide (0, 10, 20, 30, and 40 wt%) and the firing temperatures on the phase composition, microstructure, physical properties, and mechanical properties of the AZ samples were studied. The effect of titanium oxide (2, 5, and 7 wt%) and the firing temperatures on the phase composition, microstructure, physical properties, and mechanical properties of the AZ sample with 40 wt% of zinc oxide were studied. Furthermore, the optical properties, magnetic properties, and antimicrobial activity were measured. The results indicate that the increase in zinc oxide enhances the formation of zinc aluminate, which has a gahnite phase. Moreover, increasing the zinc oxide increases the apparent porosity and decreases the grain size and bulk density at various firing temperatures. On the other hand, the addition of 5 wt% titanium oxide increases the bulk density to 3.5 g/cm3 compared to 1.72 g/cm3 with no titania. The apparent porosity and compressive strength reached 5% and 69.2 MPa after 5 wt% TiO2 addition; respectively, compared to 59% and 27.2 MPa with no titania addition. The prepared samples show promising optical band gap of 2.98–3.97 eV, a mixed magnetic behavior, and favorable antibacterial activity against E. coli, S. aureus, B. cereus strains.
Experimenting with every American king
Authors: Mankowitz Poppy 
Published: October 2023

AbstractThe standard contemporary semantics for ‘every’ predict the truth of occurrences of sentences with restrictors that denote the empty set, such as ‘Every American king lives in New York’. The literature on empty restrictors has been concerned with explaining a particular violation of this prediction: many assessors consider empty-restrictor sentences to be odd rather than valued, and they are apparently more likely to do so when such sentences include determiners like ‘every’ as opposed to those like ‘no’. Empirical investigation of this issue is overdue, and I present the results of three experimental surveys. The first unexpected outcome is that there is no evidence of a contrast in assessors’ tendencies to judge sentences to be odd based on determiner type. An additional surprising result is that those assessors who assign a truth value to sentences where ‘every’ combines with an empty restrictor overwhelmingly assign the value false. The full results do not fit straightforwardly with any existing account.
Is remembering constructive imagining?
Authors: Sant’Anna André 
Published: October 2023

AbstractThe (dis)continuism debate—the debate over whether remembering is a form of imagining—is a prominent one in contemporary philosophy of memory. In recent work, Langland-Hassan (2021) has argued that this debate is best understood as a dispute over whether remembering is a form of constructive imagining. In this paper, I argue that remembering is not a form of constructive imagining because constructive processes in remembering and imagining are constrained, and hence controlled, in different ways at the level of consciousness. More specifically, I argue that remembering and imagining differ in terms of the interventions we can make on the constructive processes as they unfold. If this is correct, then a form of discontinuism is vindicated: remembering and imagining are, on this view, processes of different kinds.
Science as a counter to the erosion of truth in society
Authors: Collins Harry 
Published: October 2023

AbstractThe role of scientific values has taken on new urgency with recent changes in the politics of Western societies. The threat is the erosion of the distinction between true and false in political circles. This could rapidly lead to democracy sliding into populism thence fascism. In the light of this, philosophy and sociology of science should themselves re-examine their role. The main point of the paper is to argue that science could and should push against the erosion of truth in society. Sociological thinking has sometimes tended to erode the difference between science and ordinary thought but it should no longer ignore the political consequences and should, instead, start to take scientific values as a positive resource in society. The philosophical analysis of scientific values, which I will refer to as ‘scientific value analysis, or ‘SVA’, has championed the impact of societal values on science but should also look at the way scientific values could positively affect societal values.
Securing Moral Authority: A Cross-National Analysis of Protestant Engagement in the Implementation of Morality Policies in Western Europe
Authors: Mettang Olivia , Euchner Eva-Maria , Fischer Lisa , Menzner Jan 
Published: October 2023

AbstractChurches have a hard time defending their moral values in the political sphere of an ever more secular and liberal Western Europe. A largely neglected means of navigating this crisis is through the Church’s role as a charitable provider during the implementation of morality policies. This paper examines this type of church involvement from a cross-national and cross-sectoral perspective. We describe the activities of Protestant churches in four morality policy areas in three European countries: Germany, England, and Denmark. The variation in religious engagement observed in these areas and countries appear to be driven by the churches’ room to maneuver and their policy congruence with state goals, whereas governance capacities are secondary. Thus, the provision of social services can still serve as a means by which Protestant churches can exert moral authority, especially if these social services are related to moral issues.
From crisis to resilience: strengthening climate action in OECD countries through environmental policy and energy transition

Published: October 2023

AbstractClimate change represents a grave challenge to the global economy, environment, and societal well-being, jeopardizing their long-term sustainability. In response to this urgent issue, the study emphasizes the significance of environmental policy and energy transitions as fundamental factors in addressing the climate change crisis. The research draws upon data from OECD countries spanning the period between 1990 and 2020, utilizing robust econometric techniques to assess data properties. The study utilizes a comprehensive CS-ARDL model, incorporating multiple control variables like non-renewable energy GDP, foreign direct investment (FDI), and research and development (R&D). The results show that environmental policy and energy transitions are effective in reducing climate change impacts in the form of CO2 emissions. The non-environmental factors like GDP and FDI are positively associated and thereby accelerate climate change processes, whereas R&D promotes environmental protection by reducing CO2 emissions. Based on these findings, the study advocates for the implementation of rigorous policy measures by OECD economies to strengthen and enforce environmental policies to ensure compliance and foster sustainable practices across sectors. The study also suggests that OECD must promote energy transitions by investing in renewable energy sources at the mass level (micro and macro) and phasing out reliance on non-renewable energy.
Assessing the emissions of short sea international shipping: a case study of the Mytilini–Ayvalik route

Published: October 2023

AbstractShort sea shipping involves transporting passengers and cargo between European ports and coastal countries bordering Europe on enclosed seas. Challenges include aging fleets and environmental concerns, but efforts to reduce emissions are in progress through the use of low-sulfur fuels, hybrid and electric vessels, and improved energy efficiency. This study focuses on emissions from international short shipping routes between Mytilini and Ayvalik, using standardized emission factors to calculate CO2, SO2, NOx, PM, and HC emissions. The research aims to bridge knowledge gaps and provide insights into these emissions, identifying the main commercial ships on the route, analyzing their emissions, and discussing the findings. Overall, six ships completed the route, consuming an average of 60 L of fuel per hour per 100 HP, depending on factors like speed and total load. Notably, NOx emissions are the highest, followed by sulfur oxides, with values exceeding 12.9 and 3.5 tons, respectively. As anticipated, cruising is the shipping practice with the highest energy footprint, amounting to 695 MWh. An essential discovery is that hoteling plays a significant role in energy consumption and emissions, accounting for 152 MWh out of the total 881 MWh consumed across all shipping practices. The potential adoption of hydrogen as a fuel holds the promise of substantial reductions in greenhouse gas emissions, enhancements in air quality, and noise pollution mitigation.
The Ethical Assessment of the Stay-At-Home Order in South Africa in Light of The Universal Declaration of Bioethics And Human Rights (UNESCO)
Authors: Rheeder A. L. 
Published: October 2023

AbstractThe South African government announced the much-discussed stay-at-home order between March 27 and April 30, 2020, during what was known as lockdown level 5, which meant that citizens were not allowed to leave their homes. The objective of this study is to assess the stay-at-home order against the global principles of the UDBHR. It is deducible that, in reference to the UDBHR, the government possessed the right to curtail individual liberty, thereby not infringing on Article 5 of the UDBHR and therefore, in this context, passes the test of the UDBHR. However, it remains uncertain at present whether the limitation of freedom imposed by the South African stay-at-home order was successful in controlling the spread of COVID-19 and protecting individuals from harm. Initial investigations also indicate that individuals who are particularly vulnerable may not have received equitable treatment in accordance with the principle outlined in Article 10, therefore, it can be cautiously and modestly argued that the stay-at-home order does not withstand scrutiny when assessed against the UDBHR. Given the continued discussion about the efficacy of limiting freedom to control the spread of COVID-19, and the growing conviction that the advancement of justice is being called into question, the notion of least restriction ought to be considered seriously. Ten Have (2022) is correct in asserting that global bioethics should also seriously consider other principles beyond an almost exclusive focus on limiting individual freedom. The preliminary conclusion is that the potential implementation of the stay-at-home order in the future must be seriously reconsidered.
The beneficial effect of barley straw extract addition on the growth of two aquatic invasive alien species (Elodea nuttallii and Cabomba caroliniana) under laboratory conditions
Authors: Draga Mateusz , Gąbka Maciej 
Published: October 2023

AbstractBarley straw has been used around the world for decades as a simple, cost-effective and harmless phytoplankton growth inhibition method. Although the effect of this method on algal blooms is quite well depicted, it has not yet been tested what effect it has on submerged vascular plants and if it could be used to control the spread of alien macrophytes. In this study two highly invasive plant species: Cabomba caroliniana and Elodea nuttallii were exposed to different concentration of the barley straw extract (BSE) in laboratory conditions for a duration of four weeks. In the course of the investigations, responses of 8 traits associated with growth, biomass and chlorophyll concentration of specimens to three dosages (Low, Medium, High) of BSE corresponding to concentrations: 0.03, 0.30 and 1.50 ml l−1 were analysed. The result showed that although dry mass and total length of the plants did not differ significantly between the test groups, increase in tillering and internodes number was observed for certain concentrations of the extract. This shows that if BSE has any effect on submerged macrophytes it is a positive one and thus the method is not suitable for invasive submerged aquatic plant control. Furthermore, it is recommended that before using barley straw for algae bloom control one should make sure that there are no alien aquatic submerged plants in the area that could benefit from such a treatment.

Published: October 2023

Opinion statementTransplant oncology is a new field of medicine referred to the use of solid organ transplantation, particularly the liver, to improve prognosis and quality of life in cancer patients. In unresectable, liver-only metastases from neuroendocrine tumors (NETs) of the digestive tract, liver transplantation represents a competitive chance of cure. Due to the limited resource of donated organs, accurate patients’ selection is crucial in order to maximize transplant benefit. Several tumor- and patient-related factors should be considered. Among them, primary tumors with a low grade of differentiation (G1-G2 or Ki67 < 10%), located in a region drained by the portal system and removed before transplantation with at least 3–6 months period of disease stability observed before transplant listing, can be considered for transplantation. In case of NET located in the pancreas, extended lymphadenectomy should complement curative pancreatic resection. A number of other features are described in this review of liver transplantation for NET metastases. Comprehensive approach including various forms of non-surgical treatment and detailed planning and timing of total hepatectomy are discussed. Open issues remain on possible expansion of current criteria while maintaining the same long-term benefit demonstrated with the Milan NET criteria with respect to other non-transplant options, with particular reference to liver resection, peptide receptor radionuclide therapy, and locoregional and systemic treatments.
