Optimal enzyme allocation leads to the constrained enzyme hypothesis: the Soil Enzyme Steady Allocation Model (SESAM; v3.1)
Authors: Wutzler Thomas , Reimers Christian , Ahrens Bernhard , Schrumpf Marion
Published: April 2024

Abstract. Describing the coupling of nitrogen (N), phosphorus (P), and carbon (C) cycles of land ecosystems requires understanding microbial element use efficiencies of soil organic matter (SOM) decomposition. These efficiencies are studied by the Soil Enzyme Steady Allocation Model (SESAM) at the decadal scale. The model assumes that the soil microbial communities and their element use efficiencies develop towards an optimum where the growth of the entire community is maximized. Specifically, SESAM approximated this growth optimization by allocating resources to several SOM-degrading enzymes proportional to the revenue of these enzymes, called the Relative approach. However, a rigorous mathematical treatment of this approximation has been lacking so far. Therefore, in this study we derive explicit formulas of enzyme allocation that maximize the total return from enzymatic processing, called the Optimal approach. Further, we derive another heuristic approach that prescribes the change of allocation without the need of deriving a formulation for the optimal allocation, called the Derivative approach. When comparing predictions across these approaches, we found that the Relative approach was a special case of the Optimal approach valid at sufficiently high microbial biomass. However, at low microbial biomass, it overestimated allocation to the enzymes having lower revenues compared to the Optimal approach. The Derivative-based allocation closely tracked the Optimal allocation. These findings increase our confidence in conclusions drawn from SESAM studies. Moreover, the new developments extend the range of conditions at which valid conclusions can be drawn. Further, based on these findings we formulated the constrained enzyme hypothesis. This hypothesis provides a complementary explanation why some substrates in soil are preserved over decades, although they are often decomposed within a few years in incubation experiments. This study shows how optimality considerations lead to simplified models, new insights, and new hypotheses. This is another step in deriving a simple representation of an adaptive microbial community, which is required for coupled stoichiometric C–N–P dynamic models that are aimed to study decadal processes beyond the ecosystem scale.
HRRTLE (High Resolution Runoff and Transmission Loss Estimator): a novel tool for mapping connectivity of runoff in ephemeral stream networks to aid the siting of water harvesting structures
Authors: Delaney Robert G. , Blackburn George A. , Folkard Andrew M. , Whyatt James D.
Published: April 2024

Abstract. Water harvesting is predominantly carried out in arid and semi-arid regions. Site selection studies often rely on a methodology that calculates runoff using curve numbers to generate runoff maps. These maps, typically used as part of a multi-criteria selection process, identify areas conducive to the siting of water harvesting structures. However, traditional runoff maps do not account for transmission losses that occur along the surface flow path to the catchment outlet, and these losses can be significant in arid and semi-arid regions. Here we introduce a methodology that incorporates a curve number runoff method while also addressing transmission losses. Our approach, utilising three global datasets, was validated against observed runoff data from 28 catchments worldwide, and infers hydraulic characteristics of both overland and channel flow from curve number values. This involves leveraging the curve number dataset twice: initially for calculating runoff and subsequently for forecasting transmission losses. The outcomes include a runoff connectivity map, at a spatial resolution of 250 m × 250 m, presenting the runoff depth (in mm) for each pixel based on the direct runoff generated at that pixel and reaching the catchment outlet. This connectivity map aids planners in comprehending the dynamics of surface runoff towards a catchment outlet, assisting in identifying potential locations for future water harvesting structures. The process integrates 38 years of precipitation data, enabling predictions not only for average annual runoff but also for the return periods of various annual runoff volumes. Despite the simplicity of the model, a positive Nash-Sutcliffe efficiency value was observed in 11 out of the 28 catchments.
Effect of Blade Inclination Angle for Straight Bladed Vertical Axis Wind Turbines
Authors: Morgan Laurence Boyd , Amiri Abbas Kazemi , Leithead William , Carroll James
Published: April 2024

Abstract. Vertical Axis Wind Turbines (VAWTs) have received renewed research interest in the offshore environment due to a number of design synergies that have the potential to decrease the cost of energy for offshore wind. Many studies have been completed on the rotor design for straight bladed (H) rotors however there is sparse information on the effect of blade inclination angle on VAWT aerodynamic performance, and the optimal blade design of VAWTs with inclined blades (V-rotors) for maximum power capture. This paper presents a systematic study into the effect of blade inclination angle, chord distribution, and blade length on VAWT performance. In the case of fixed chord length blades, it is found that significant power gains are available through blade inclination, between 10 % and 68 %, dependent on blade length. This is driven by the increase in rotor swept area. Further investigation indicates that despite this, under maximum blade stress limitations the most economical solution for fixed chord length blades are H-rotors. Optimal chord distributions to maximise the rotor power coefficient are then obtained, and a natural blade taper is observed. Significant power gains, between 10 % and 69 % dependent on blade length, are observed through blade inclination. However, consideration must be taken to limit blade mass. For a given power rating, whilst satisfying limitations on maximum blade root bending stress, it is found that blade volume can be reduced between 9 % and 42 % dependent on blade length, and rotor torque can be reduced between 3 % and 9 %. This indicates the potential of V-rotors to reduce the cost of energy compared to H-rotors in traditional VAWT designs. Additionally, inclined blades are shown to increase the operational tip speed ratio, demonstrating their applicability to turbines using secondary rotors, such as the X-Rotor.
Testing Anthropocentrism: Lacan and the Animal Imago
Authors: Dalziell Jacqueline
Published: April 2024

In an effort to complicate the human subject, this article considers the critical insights of psychoanalytic thinker Jacques Lacan, focusing in particular on his essay, “The Mirror Stage as Formative of the Function of the I As Revealed in Psychoanalytic Experience” (1949). ‘The Mirror Stage’ explains how we break from nature, differentiate ourselves from the animal and graduate from primordial subsistence as psychically folded into the first lightning strike of recognition that arrives with/as self-reflection. Curiously however, in sustaining his argument about the human specificity of the mirror stage phenomenon, Lacan relies upon ethological research on nonhuman self-recognition. This reliance of his argument on the figure of the animal has largely been interpreted in two ways: as an inconsequential detail, undeserving of theoretical exploration, or, as confirmation of Lacan’s self-evident anthropocentrism. For instance, Buse (2017) and Ziser (2007) have noted the significant discrepancies within ‘The Mirror Stage’ between Lacan’s understanding of primate self-recognition, and that of his main source, Wolfgang Köhler. Although, both thinkers hold the position that Lacan’s treatment of the animal in ‘The Mirror Stage’ provides sufficient textual evidence for a reading that endorses human exceptionalism. Departing from this prior research, I focus on these same textual irregularities within ‘The Mirror Stage,’ yet see something quite different taking place in these moments. In order to preserve the complexity of Lacanian material, in a detailed examination utilising close reading, I pick apart long passages of both Lacan and his sources and conclude that Lacan’s position on the animal is both ambivalent and ambiguous in character. This culminates in a lack of clarity regarding how to understand Lacan’s position on both the animal, and correlatively the human. In turn, acknowledging this uncertainty provides a novel way to approach this seminal text, and a justification to revise accusations of anthropocentrism, alongside dominant interpretations more broadly.

Analysis of the Quality of Entities Digital Platform at the ASEAN Secretariat Using WebQual 4.0
Authors: Nugraha Johan Yudha , Hasanah Nur , Hermadi Irman
Published: April 2024

Entities associated with ASEAN are accredited organizations that adhere to the goals, principles, policies, guidelines, and other decisions of ASEAN. Accredited entities are required to support the purposes and objectives of ASEAN. ASEAN's engagement with accredited entities is determined in Article 16 and listed under Annex II of the ASEAN Charter. These Entities are also guided by rules, procedures, and criteria for the involvement of entities associated with ASEAN and its annexes.
Any official organization within the Southeast Asian region that wants to be accredited must follow the applicable procedures and register to become part of the ASEAN Entities. The registration procedure involves submitting printed documents to the ASEAN Secretariat office. Over time, such procedures have faced various challenges, including environmental issues, document storage, lengthy processing times, and restrictions on physical activities during the COVID-19 pandemic. Therefore, the idea of digitizing the registration activities of ASEAN Entities emerged through the Entities Digital Platform (EDP).
After more than two years of operation, the EDP requires evaluation and feature development to accommodate the needs of its users. Thus, the objectives of this research are to analyze Entities Digital Platform quality. This research is qualitative, with primary data obtained through questionnaires. The methods used in this research are descriptive analysis through WebQual 4.0 to assess the platform quality.

Keywords: ASEAN, Entities Digital Platform, WebQual, Importance Performance Analysis.

Published: April 2024

In the present BANI (brittle, anxious, nonlinear, and incomprehensible) world, agility and organizational change holds a great significance in an organization for its survival and growth. As per prior studies, organizational change doesn’t deliver the anticipated results due to various reasons and challenges. Employee resistance being the main concern, leadership holds a great importance in handling resistance, managing conflicts, dealing with setbacks, and empowering the team. Transformational leaderships are often termed as change agents as they support and uplift their teams’ creativity and innovation, thus motivating them towards change. This study’s primary goal is to examine and discuss the mapping of research landscape, depicting the relationship between agile transformational leadership and organizational change management. For this analysis, bibliographical data of 1848 documents published between 2014 to 2023, was extracted from Dimensions database after applying exclusion criteria. This extracted database is used for analyzing and visualizing citation patterns, evolution, and growth of subject- performance, publication and journal sources, research locations, co-authorship relations and co-occurrence of keywords, using bibliometric software, VOSviewer and RStudio. The research shares the advancement of this topic in last ten years, providing theoretical support and substructure for future studies. As per this analysis, transformational leadership can be of a great support to organizations due to it affiliative management style, leading to a positive work environment that embraces change and innovation.
Control Unit of a Three-Ports Hybrid Converter of a Microgrid Based on Ternary Logic Circuits
Authors: Osseily Hassan Amin
Published: April 2024

This paper, provides the design and simulation of the control modes of three different power sources that are commonly used in hybrid systems especially when combining the sources of photovoltaic (PV), electric vehicles (EV) and Energy storage system (ESS). The control scenarios discuss the different combinations of sources and loads based on ternary logic system (0,1,2) that has many advantages over the classical binary logic system (0,1). To prove that, first, the ternary logic gates must be verified and simulated as MOSFET by Matlab / Simulink then a ternary logic control (TLCU) will be designed. TLCU can select the right direction of power flow from the energy source to the load based on the ternary truth table that shows the relationship between the inputs (ternary states of sources and loads) and each output that has only two states (ON or Off). At the end of the paper, the circuit of a ternary logic control circuit that can optimize the number of used elements of MOSFET is designed and tested. Comparing to binary, it is expected not only to optimize the number of MOSFET but also to accelerate the speed of operation.
War, mobilization, and fiscal capacity: testing the bellicist theory in Greece, 1833-1939
Authors:   Department of Political Science and History, Panteion University, Athens, Greece, Kakridis Andreas ,   Bank of Greece, Athens, Greece
Published: April 2024

Constructing a new dataset of Greek public revenues and expenditures for the years 1833 to 1939, this paper finds that war mobilizations undermined tax revenues in the short run, but helped the Greek state increase its fiscal capacity in the long run. Tax revenues increased on the heels of major spikes in defense expenditures, even in cases where mobilizations did not escalate to war. But even in normal times, changes in military expenditures had a stronger effect on taxes, compared to similar changes in civilian outlays. The paper thus provides both data and evidence in support of bellicist theories of state formation for Greece, while also proposing a new approach to testing for the effects of war on fiscal capacity.

Problemlösungskompetenz stellt eine grundlegende Fähigkeit zur erfolgreichen Bewältigung vielfältiger Herausforderungen in unterschiedlichen Kontexten dar, weshalb ihrer Entwicklung und Förderung eine zentrale Rolle im Schul- und Hochschulbereich zukommt. Zu diesem Zweck können Planspiele eingesetzt werden, die als Methode aktiven und praxisorientierten Lernens bereits seit Langem etabliert sind. Im Zuge des digitalen Wandels hat sich das Spektrum an Planspiel-Varianten durch die Möglichkeiten synchroner und asynchroner virtueller Lehre jedoch deutlich erweitert. Der vorliegende Artikel untersucht die Auswirkungen der Integration von Asynchronität in Planspielen auf die Problemlösungskompetenz im Vergleich zu synchronen Planspielen. Ausgehend von grundlegenden terminologischen Abgrenzungen sowie einer Darstellung des aktuellen Stands der Forschung werden zunächst Handlungsempfehlungen hinsichtlich der Einbeziehung asynchroner Elemente in Planspiele abgeleitet. Anschließend wird deren Umsetzung anhand eines Fallbeispiels, das im Rahmen eines Praxisprojekts an einer Fachhochschule realisiert wurde, dargelegt. Dabei kann gezeigt werden, wie die Entwicklung von Problemlösungskompetenz im Zuge eines Planspiels im Blended Learning Format durch die Integration asynchroner Aktivitäten, Aufgaben und Kommunikationsmöglichkeiten auf vielfältige Weise unterstützt werden kann.

In Vitro α-Glucosidase, α-Amylase Inhibitory and Antioxidant Activities of Root Crude Extract and Solvent Fractions of Arbutus unedo L. (Ericaceae)
Authors: Beyatli Ahmet
Published: April 2024

Roots of Arbutus unedo (Ericaceae) have been used traditionally to treat diabetes in some countries. Conducting more experiments is needed to support this plant's potential antidiabetic properties, though. Ethanolic extract yielded by cold maceration was subjected into fractionation to get hexane, chloroform, ethyl acetate, butanol, and aqueous fractions. Total phenolic contents and antioxidant capacity have been estimated utilizing 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and ferric ion reducing antioxidant potential (FRAP) assay models, respectively. Antidiabetic activity of A. unedo extracts were evaluated using in vitro α-glucosidase, α-amylase inhibition activity. The ethanol extract had the highest antioxidant activity among used extracts. While the results of both α-glucosidase, α-amylase enzyme inhibition activity was detected to be dose-dependent, the strongest inhibition activity for α-glucosidase and α-amylase was shown by ethanol extract (526.65 and 522.66 µg mL-1 respectively) compared to the standard acarbose. Results demonstrated the beneficial effects of A. unedo extracts by showing antioxidant and antidiabetic activities.

Virosome: A virus created specifically to deliver a vaccination

Published: April 2024

Liposomes are particularly interesting as a novel medication delivery technology because of their potential as gene carriers and capacity to reduce drug toxicity. Optimized lipid components have been developed to prevent the uptake of reticuloendothelial system (RES). The liposome surface has been altered with antibodies or ligands that are recognized by particular cell types in order to increase tissues localization. Liposomes and fusiogenic viral envelope protein have been combined to form new virosomes, which introduce molecules directly into cells, hence improving the efficiency of gene delivery. Efforts had been made to use virosomes as adjuvants or antibodies, and also for means of drug delivery and organics, for therapeutic applications because they are biocompatible, nontoxic, non-auto-immunogenetic and, biodegradable. In contrast with conventional methods of vaccine development, a vaccine based on virosomes represents a new era in the field of immunization since it strikes a balance between acceptability and efficacy because of its immune-stimulating mechanism. The ability of virosomes to function as a therapeutic target and vaccine adjuvant, as well as their capacity to transport a different kind of substances, such as proteins, peptides, and nucleic and their ability to target specific drugs. The main topics of this article are the basics of virosomes, their formulation, composition, and advantages, development, current clinical status, interactions with the immune system, recent developments, and virosome-related research, as well as the safety, effectiveness, and tolerability of vaccines based on virosomes and their prospects for the future.

This article provides an understanding of Hugh Lacey's ideas regarding the influence of values in contemporary science. We explore the interaction between scientific activity and values, fostering critical awareness of scientific practice and its impact on society. The aim is to fill gaps in the comprehension of cognitive, social, and ethical values, considering how they have been shaped by technological transformations and sociocultural crises. A comprehensive literature review examines Lacey's key tenets presented in works such as "Values and Scientific Activity 1 and 2" and Oliveira's "From Cognitive Science to Dialectic", as well as articles in scientific databases and communications with the philosopher in 2023. According to him, values and science should be intrinsically linked, provided there is impartiality in scientific assessments. This relationship does not compromise the ongoing pursuit of a robust understanding of the phenomena in the world. The results highlight the relevance of Lacey's perspectives on values in contemporary science, as in contexts such as transgenic research, which raises crucial ethical questions. The applications of such research can have profound impacts, highlighting the importance of ethics.

The composition and dynamics of plant communities are determined by the survival, dispersal and persistence of seeds in the soil, some of the fundamental aspects for understanding plant biology, among which seed dormancy is of particular importance. The aim of this work was to find out whether seed dormancy is affected by certain substrates in order to improve the production of Tabernaemontana heterophylla seedlings. Treatments were carried out with different substrates (T1. Sand, T2. Vegetable clay, T3. Vegetable clay + sand (1:1 ratio), T4. Vermiculite, T5. Cattle manure, T6. Sawdust and T7. Organic compost) in 7 x 4 factorial schemes, the results of which were subjected to an analysis of variance and a comparison of means with the Tukey test at a probability of 5%. The seeds with visible germination structure (hypocotyl) showed an apical meristem in a dormant stage. The number of normal seedlings did not exceed 25% of the germinated seeds in all treatments, with a high proportion of non-viable seeds observed. In the absence of technical information on overcome dormancy, it is important to use strategies that stimulate germination and subsequent seedling growth. The slow germination combined with the presence of dormancy in the hypocotyledon were factors that negatively affected the propagation of the species studied.

A mesterséges intelligenciát (MI-t) sokan a GPT-vel azonosítják: egy test nélkül élő intelligenciával, ami mindenhez ért. Holott rengeteg MI-t használunk évek óta, és fel sem tűnt sokaknak. Hogy milyen MI típusok vannak, mire használhatóak, megbízhatóak-e és hogy tényleg gondolkodnak-e, fontos tudni. Mivel az MI területei robbanásszerűen fejlődnek, ezért előfordulhat, hogy a ma még aktuális ismeret holnap már elavult lesz. Fontos tehát, hogy naprakészen tartsuk tudásunkat és utánanézzünk dolgoknak. Az MI-kre szükség lesz a jövőben, ezért tudnunk kell mi történik a megadott adatokkal, milyen kiberbiztonsági és adatvédelmi problémák várhatóak, illetve, hogy felhasználható-e egy generált mű jogi felelősség nélkül, valamint van-e jogi szabályozás.

Published: April 2024

Objective: Recently a novel hydraulic-mechanical hybrid vertical lifting system was proposed for deep-sea mining. Accurate prediction of conveying resistance is important for the engineering design of the system. Plug flow of coarse particles is the main flow regime in the system. So far rare attention has been paid to the pressure drop prediction of plug flow of coarse particles. This paper aims to investigate eight theoretical pressure drop models on the applicability to predict the pressure drop of plug flow. Methods: Eight theoretical pressure drop models were studied. In addition, a hydraulic-mechanical hybrid vertical lifting test setup was developed. The novelty of this experimental work is that plug flow of coarse particles is formed and the lifting force of the plug can be measured with the test setup. Tests were conducted with varying particle sizes, lifting speeds and plug weights. The particle size is varied among 13, 18, and 25mm. The lifting speed is varied from 0.02m/s to 0.1m/s. The plug weight varies from 5 to 10kg. The range of Reynolds number for the tested particles is between 208 and 2,000. Results: Prediction errors of eight pressure drop models are derived and compared with the experimental data collected during this study. It was found that similar prediction trends are observed for all pressure drop models under most test conditions. Except the Rose model, all models produce average prediction errors less than 15%. The average prediction error for the Rose model is 20.59%. The average prediction error for the Ergun model is 12.43%. Conclusion: From this study it can be seen that the Ergun model produces the smallest prediction error among the eight selected pressure drop models for the given experimental conditions. Therefore, the Ergun model is considered to be most applicable for the calculation of the conveying resistance for the proposed vertical lifting system.
Friction Stir Processing of AA6061 Aluminum Alloy Reinforced with Ceramic Particles for Enhanced Mechanical Properties
Authors: B Moustafa Essam
Published: April 2024

This study investigates the effect of incorporating ceramic particles, specifically Chromium Carbide (CrC), Tantalum Carbide (TaC), and Niobium Carbide (NbC), on the mechanical properties of AA6061 aluminum alloy. The investigation uses the Friction Stir Processing (FSP) fabrication technique. The results indicate substantial enhancements in mechanical properties compared to the material without reinforcement. Reinforced composites display elevated longitudinal and shear velocities, which signifies enhanced rigidity and ability to withstand deformation when subjected to different force directions. Using CrC and TaC reinforcements in the AA6061/CrC+TaC composite led to the maximum velocities for both wave types, indicating a notably rigid composite material. Introducing ceramic particles to AA6061 significantly augments Young’s and shear modulus, indicating improved strength and stiffness. AA6061/CrC+TaC showed the most notable enhancement of all the reinforcements, underscoring the potential of using combined reinforcements. Incorporating ceramic particles into AA6061 greatly enhances its microhardness and Vickers hardness. The addition of Tantalum Carbide (TaC) as a reinforcement resulted in the most significant enhancement, indicating a robust interaction with the matrix. Notably, composites with a combination of reinforcements (CrC+TaC and CrC+NbC) displayed even greater hardness, possibly due to synergistic effects.

Published: April 2024

This study aims to investigate the relationship between international tourism and total trade, including exports and imports, for the twenty most visited countries. In order to accurately assess the relationship, the study employs the Emirmahmutoglu and Kose (2011) causality analysis, which accounts for cross-sectional dependency and heterogeneity. The empirical results show a unidirectional causality running from total trade, exports, and imports to international tourist arrivals for Germany, India, Mexico, and the Netherlands. Conversely, the causality runs from international tourist arrivals to total trade, exports, and imports for Portugal, Russia, and Spain (except imports). Additionally, a bidirectional causality link between international trade and tourism is found for China, indicating that both tourism and trade mutually reinforce each other. These results highlight the importance of considering the direction of causality in the relationship between tourism and trade, and developing targeted policies that take into account the unique characteristics of each country.
