Abstract A fitness landscape is a map between the genotype and its reproductive success in a given environment. The topography of fitness landscapes largely governs adaptive dynamics, constraining evolutionary trajectories and the predictability of evolution. Theory suggests that this topography can be “deformed” by mutations that produce substantial changes to the environment. In spite of its importance, the deformability of fitness landscapes has not been systematically studied beyond abstract models, and little is known about its reach and consequences in empirical systems. Here we have systematically characterized the deformability of the genome-wide metabolic fitness landscape of the bacterium E. coli . Deformability is quantified by the non-commutativity of epistatic interactions, which we experimentally demonstrate in mutant strains on the path to an evolutionary innovation. Our analysis shows that the deformation of fitness landscapes by metabolic mutations rarely affects evolutionary trajectories in the short-range. However, mutations with large environmental effects leave these as a “legacy”, producing long-range landscape deformations in distant regions of the genotype space that affect the fitness of later descendants. Our methods and results provide the basis for an integration between adaptive and eco-evolutionary dynamics with complex genetics and genomics.

The production of hydrogen (H2) from water hyacinth (WH) can contribute to reducing both the negative impact of WH on ecosystems and dependence on fossil fuels. In this study, the combination of dark fermentation (DF) and microbial electrolysis cell (MEC) in a single reactor, namely, sDFMEC, was investigated to improve the H2 productivity of WH. Furthermore, the intermittently applied voltage (I-Eapp) scheme and various methane (CH4) inhibition methods, including air exposure, heat treatment, and chloroform (CHCl3) addition, were applied for performance enhancement purposes. The findings indicated that with a sufficient duty time of external energy input (less than 1 hour), the intermittent mode can enhance the performance of WH-fed sDFMEC but does not significantly inhibit CH4 formation. While air exposure and heat treatment damaged both methanogens and exoelectrogens, lowering sDFMEC performance, additional CHCl3 showed the best selective and long-term inhibition on methanogens (over 350 operation hours without further addition). Overall, the combination of the I-Eapp scheme and CHCl3 applied in WH-fed sDFMEC achieved a yield of 670.1 ± 15.2 mL − H 2 / g − VS , around 160% higher than the normal condition.

Microbial communities colonizing the hulls of vulnerable vessels, such as those with lengthy harbor residence instances, low speeds, and Long periods of motionlessness in Water changes as a result of environmental variables during ocean voyages are expected but rarely studied. Microbial communities were discovered on the hull of the TS Golden Bear, a ship operated differently during a voyage from the port of San Francisco to the South Pacific and back. We demonstrate that bacterial communities are highly resilient and can withstand physiologically demanding journeys through extreme temperature and salinity changes. After leaving San Francisco Harbor south toward Long Beach, a 42% decrease in biomass from bacteria and a 62% decrease in algal cellular abundance suggest a community-wide negative response to increasing salinity and temperature. The ship lost 36% of its biomass and 26% of its cellular abundance when it reached the hot, high-salinity seas off Hawaii. In Hawaii the efficiency of cellular fluorescence was reduced by 17%. Following a return to temperate seas off the coast of Vallejo, California, biomass rose 230%, cellular abundance remained constant, and intracellular fluorescence efficiency increased. This study's methods for analysing microbial (and macrofouling) populations are efficient and cost-effective. The goal of this paper is to solve Scale weights are based on GRA integers with interval values. The Gray Relational Analysis (GRA) method is used to solve MCDM problems with unknown knowledge. The traditional GRA method's basic idea, Evaluation of scale weights, is used to create some optimisation models. “Vallejo, Long Beach, Lahaina and Vallejo taken this alternative in this method and evaluation parameters is Parameters C1 for evaluating practices is Temp (◦C), C2 for Salinity, C3 for Pelagic cellular abundance (×103 cells/L), C4 for Pelagic biomass (μg Chl a/L), C5 for Pelagic photosynthetic efficiency (Fv/Fm) and C6 for Average speed of advance (kts)”. This analysis's conventional The GRA method's fundamental concept Determines the long-term solution from the short-term and negative-best solutions, but this comparison is not deemed significant. “From the result it is seen that Vallejo 1, CA is got the first rank where as is the Long Beach, CA is having the lowest rank. This paper shows the Vallejo 1 CA highest biofouling regulations recently set by California State Lands.”

The ultrahigh-aspect-ratio wing (UHARW) concept is a promising configuration to achieve future sustainable aviation goals. Twin-fuselage (TF) and strut-braced-wing (SBW) configurations are characterized by smaller structural bending moments and shear forces in the wing and are promising concepts for realizing UHARW designs. This paper addresses the aerostructural optimization problem of TF and SBW configurations with UHARW by using a coupled adjoint aerostructural optimization tool, which is composed of a geometrically nonlinear structural solver and a quasi-three-dimensional natural laminar flow (NLF) aerodynamic solver. The optimization results show significant improvements in fuel efficiency and performance for the TF and SBW aircraft, with fuel mass reductions of 13 and 10%, respectively, compared to the corresponding baseline aircraft designed in the conceptual design phase. In comparison to the original reference aircraft A320neo, the optimized TF and SBW have 48 and 31% lower fuel weights, respectively. The NLF range of both upper and lower wing surfaces is expanded during optimization. The optimized SBW configuration has a wing aspect ratio of 26.01, while the optimized TF has a wing aspect ratio of 20.74, indicating that the SBW concept is more conducive to realizing UHARW design compared with the TF configuration studied in this work. The optimized TF aircraft has a lighter fuel weight and gross weight compared to the optimized SBW aircraft, which is because the TF aircraft has a lighter operational empty weight, including a lighter fuselage structural weight, landing gear weight, etc., whereas the top-level aircraft requirements are the same for both aircraft, including range, payload, and cruise Mach.

This paper deals with an optimal control approach for commercial aircraft trajectory planning, focusing on the vertical path and the minimization of the fuel burned. The main contribution is the optimization of the whole trajectory, also called the mission, without prior separation into different flight phases (climb, cruise, and descent), contrary to traditional approaches that consider the flight phases sequentially. The proposed optimal control problem (OCP) is formulated and then solved using a direct collocation method. Initial results yield optimal trajectories with a gradual climb during the cruise (climb cruise), which correspond to theoretical trajectories that minimize fuel consumption. Furthermore, a penalization is introduced to ensure vertical profiles featuring horizontal cruise levels on so-called flight levels, compliant with current air traffic management regulations. The use of direct methods to address this OCP induces large nonlinear optimization problems that are solved using an interior point method. This methodology is likely to lead to poor local optima, but a simple multistart heuristic shows that the solutions found for standard problems appear to be globally optimal. Such an approach does not need to impose a priori the cruise flight levels and is suitable for commercial aircraft flight planning purposes. It leads to fuel saving and subsequently to important improvements against environmental impact by reducing [Formula: see text] emissions.

Distributed electric propulsion in aircraft design is a concept that involves placing multiple electric motors across the aircraft’s airframe. Such a system has the potential to contribute to sustainable aviation by significantly reducing greenhouse gas emissions, minimizing noise pollution, improving fuel efficiency, and encouraging the use of cleaner energy sources. This paper investigates the impact and relationship of turbo-electric propulsion component characteristics with three performance quantities of interest: lift-to-drag ratio, operating empty weight, and fuel burn. Using the small- and medium-range “DRAGON” aircraft concept, we performed design exploration enabled through the explainable surrogate model strategy. This work uses Shapley additive explanations to illuminate the dependencies of these critical performance metrics on specific turbo-electric propulsion component characteristics, offering valuable insights to inform future advancements in electric propulsion technology. Through global sensitivity analysis, the study reveals a significant impact of electrical power unit (EPU) power density on lift-to-drag ratio, alongside notable roles played by EPU-specific power and applied voltage. For operating empty weight, EPU-specific power and voltage are highlighted as critical factors, while turboshaft power-specific fuel consumption notably influences fuel burn. The analysis concludes by exploring the implications of the insights for the future development of turbo-electric propulsion technology.

Purpose Reducing aircraft fuel consumption has become a paramount research area, focusing on optimizing operational parameters like speed and altitude during the cruise phase. However, the existing methods for fuel reduction often rely on complex experimental calculations and data extraction from embedded systems, making practical implementation challenging. To address this, this study aims to devise a simple and accessible approach using available information. Design/methodology/approach In this paper, a novel analytic method to estimate and optimize fuel consumption for aircraft equipped with jet engines is proposed, with a particular emphasis on speed and altitude parameters. The dynamic variations in weight caused by fuel consumption during flight are also accounted for. The derived fuel consumption equation was rigorously validated by applying it to the Boeing 737–700 and comparing the results against the fuel consumption reference tables provided in the Boeing manual. Remarkably, the equation yielded closely aligned outcomes across various altitudes studied. In the second part of this paper, a pioneering approach is introduced by leveraging the particle swarm optimization algorithm (PSO). This novel application of PSO allows us to explore the equation’s potential in finding the optimal altitude and speed for an actual flight from Algiers to Brussels. Findings The results demonstrate that using the main findings of this study, including the innovative equation and the application of PSO, significantly simplifies and expedites the process of determining the ideal parameters, showcasing the practical applicability of the approach. Research limitations/implications The suggested methodology stands out for its simplicity and practicality, particularly when compared to alternative approaches, owing to the ready availability of data for utilization. Nevertheless, its applicability is limited in scenarios where zero wind effects are a prevailing factor. Originality/value The research opens up new possibilities for fuel-efficient aviation, with a particular focus on the development of a unique fuel consumption equation and the pioneering use of the PSO algorithm for optimizing flight parameters. This study’s accessible approach can pave the way for more environmentally conscious and economical flight operations.

The aviation sector needs to become climate neutral with net zero emissions by 2050 in order to meet the Fly the Green Deal targets. Hydrogen has been identified as a potential energy source that could help the sector meet these ambitious targets. This study evaluated a new hybrid-electric hydrogen aircraft concept against conventional Jet-A1 and power-to-liquid (PtL) aircraft concepts in terms of economic and environmental impacts. The assessment methods that we adopted were adapted specifically for this purpose. The life cycles of the aircraft were modeled using discrete event simulations, and the results show that the hydrogen concept has similar costs to the conventional PtL concept and double the life-cycle [Formula: see text]-equivalent savings compared to the conventional Jet-A1 concept. As such, the method allows early comparison of different aircraft concepts.

The optimization of novel aircraft Environmental Control System (ECS) architectures necessitates the support of complex numerical simulations. Within the framework of the more electric aircraft approach, a promising strategy to enhance the overall efficiency of traditional ECS involves the incorporation of vapor compression systems (VCSs), which offer superior cooling efficiency compared to conventional air cycle machines. In this study, a Modelica/Dymola library for simulating VCSs has been developed, with a focused emphasis on three critical attributes: numerical robustness, accuracy, and minimal computational time. To successfully integrate and simulate the VCS model into an entire ECS model, these characteristics are essential. An appropriate tradeoff has been achieved between the computational cost of the VCS model and its ability to accurately predict the system’s physical behavior (the heat exchangers have been modeled using a partial dynamic approach to optimize both robustness and computational efficiency). The VCS model has undergone thorough testing and has been seamlessly integrated into a representative ECS model to replicate a typical commercial airplane flight mission. A comparative analysis of the advantages offered by a variable-speed compressor versus a fixed-speed one has been conducted, revealing potential energy savings of up to 40%. Furthermore, the incorporation of an internal heat exchanger has led to additional energy savings exceeding 5%.

This study aims to track the EU’s shift from fuel dependence to sustainable mobility, assessing current impacts and future efforts for low- and zero-emission vehicles and renewable fuels to reduce crude hydrocarbon imports and greenhouse gas emissions. The paper uses methods of composite indices of fuel dependence and greenhouse gas emission intensity, decomposition analysis for crude hydrocarbon imports and greenhouse gas emissions, and the causal relationship between transport traffic and sustainable mobility objectives. Empirical results indicate that deploying sustainable mobility in the EU saved 10 million tons of crude oil imports and prevented 49 million tCO2eq emissions. Advancements in sustainable mobility were more effective in curbing greenhouse gas emissions (4.7%) than in reducing crude hydrocarbon imports (1.9%) from 2013 to 2022. Projections for the EU’s 2025 objectives indicate significant efforts needed to avoid an extra 61 million tCO2eq, including adding over 13 million zero-emission transport units and producing about 2 million tons of sustainable fuel. Both targets are currently at risk. The study highlights the latent potential in other hydrocarbons that can be transformed from non-fossil energy sources. Therefore, monitoring the impact of sustainable mobility is a crucial task in reducing fuel dependence and greenhouse gas emissions from transport. It enables informed decisions and strategy adaptations and ensures that environmental and economic targets are met both timely and effectively.

Given the increasing momentum globally towards sustainable transportation, the remanufacturing of used electric vehicle lithium-ion batteries (EV LIBs) emerges as a critical opportunity to promote the principles of the circular economy. Existing research highlights the significance of remanufacturing in resource conservation and waste reduction. Nevertheless, detailed insights into South Africa’s (SA’s) specific capabilities and strategic approaches in the context of used EV LIBs remain sparse. By utilizing in-depth interviews with fifteen key industry stakeholders and drawing on institutional theory, this qualitative study evaluates SA’s infrastructure, technical expertise, and regulatory frameworks in the EV LIB remanufacturing sector to address this gap. The findings reveal proactive strategies, including technical expertise, sustainable infrastructure, and robust regulatory frameworks aligned with global standards. This study proposes strategic initiatives like the Interdisciplinary Innovation Hub and Mobile Remanufacturing Labs, which are analytically derived from stakeholder insights and aim to predict potential pathways for workforce development, especially in rural areas. Innovative training programs, including the Virtual Reality Consortium, Circular Economy Institutes, and the Real-world Challenges Program, will ensure a skilled workforce committed to sustainability and circular economy principles. The conclusions highlight SA’s potential to become a leader in EV LIB remanufacturing by integrating circular economy principles, enhancing technical expertise, and fostering international collaboration.

Owing to the scarcity of critical metal resources such as lithium and cobalt, as well as the urgent need for environmental protection, the efficient regeneration of cathode materials for lithium-ion batteries (LIBs) has become a core issue in supporting the sustainable development of the electric vehicle industry. At present, the industrial sector mainly relies on pyrometallurgy and hydrometallurgy technologies to recover metals, but the former is limited by high energy consumption and greenhouse gas emissions, while the latter faces the challenges of chemical contamination and high cost. Therefore, there is an urgent need to develop green and economical alternative technologies to avoid the environmental risks caused by landfills of used batteries and achieve resource circulation. In this study, the feasibility of emerging processes such as bio-metallurgy (microbial leaching), eutectic solvents (DES), and direct regeneration was systematically evaluated. Based on this, it is proposed to optimize process efficiency by integrating multiple technologies (such as microwave-assisted enhanced reaction and biomass co-reduction), and promote policy guidance and standardized design, to accelerate the transformation of the LIB industry to a circular economy and contribute to the global carbon neutrality goal and sustainable resource management.

Electric discharge in deep-sea hydrothermal fields leads us to expect the existence of electroactive microbial ecosystems in the environments. Electrochemical properties such as electric field distribution on the seafloor and electrical conductivity of the rock can be useful indicators of searching electroactive microbial community in natural environments. We performed electric field measurements in deep-sea hydrothermal fields and collected rock samples by a remotely operative vehicle (ROV) operation. Several spots on the seafloor with strong electric fields were detected, which included both active hydrothermal vent areas and inactive sulfide deposits far from the vents. The electrical conductivity of the rock samples was correlated with the copper and iron sulfide content. Microbial community compositions of the rock samples were characterized by small subunit (SSU) rRNA gene amplicon sequencing analysis. The abundance of several microbial components, which are highly related to electroactive microorganisms such as Geobacteraceae and Thiomicrorhabdus, was affected by the electrical properties of rock samples. The results suggested that electrochemical properties on the seafloor would be related to the abundance of possible electroactive microbial populations, and that the electrochemical survey may be a powerful tool for exploring electroactive ecosystems.

PEV（pure electric vehicle）promotion can not only mitigate the recent traditional vehicle contradiction between supply and demand of energy, solve the vehicle energy problem after the exhaustion of fossil fuel, but also improve environment quality and energy utilization efficiency.But PEV promotion is restricted by infrastructures such as energy, power supply, charging station and so on. According to the composition characteristics of Chinese primary energy, situation of Chinese power industry and requirement of power infrastructures of pure electric vehicle, I analyzed the shortcomings in the power industry while PEV are promoted in China. There are four major problems in PEV promotion. First, in China more than 70% power supply is from coal, and the average coal consumption of power generation is high. Second, electricity generation per person-year of China is far less than that of developed countries, and power shortage exists in some areas. Third, the stability of power supply is poor because it can be easily affected by some uncertain factors, such as the supply of water, coal and natural gas. Furthermore, current power capacity can not meet the requirements of the PEV promotion. In order to promote PEV, power industry must acquire high power efficiency, sufficient power supply, and extensive use of clean fuel or renewable energy etc. EVS25 Copyright.

Yet, aspects such as the mechanical properties of short fibre composites need to be characterised to fully identify the capabilities and opportunities for recycled carbon fibre in the automotive industry. Consequently, this paper aims to ascertain the potential of recycled carbon fibre materials for automotive manufacturing by considering mechanical properties, design implications, and resulting costs and sustainability. Destructive testing is employed to characterise the mechanical properties of virgin carbon fibre (VCF), recycled carbon fibre (RCF) using pyrolysis, and blended recycled carbon fibre (BRCF) comprising 50% polypropylene fibre. Here we quantify (i) the reduction in mechanical properties, namely the tensile modulus and breaking strength, (ii) the resulting increase in required thickness and therefore mass for manufactured parts and (iii) the reduction in cost and embodied energy achieved for RCF and BRCF compared to VCF, based on both a stiffness- and a strength-driven design criterion. Furthermore, we present a decision-making methodology revealing BRCF as the most cost-effective solution, while RCF proves to be the most sustainable alternative. These results provide a novel quantitative assessment of recycled carbon fibre for automotive manufacturing and may contribute to future developments in sustainable composite manufacturing in the automotive industry.

Passenger comfort is an important parameter in the design process of the car. Noise caused by many factors in the vehicle significantly affects passenger comfort. Insulators are used to reduce noise and these insulators are usually made of fibrous or porous petrochemical-based materials. Recently, natural materials have begun to replace petrochemical-based materials due to environmental and health problems. Natural fiber materials offer alternatives such as felts made from recycled cotton, hemp, and kapok fibers. These materials have various acoustic performance properties depending on their density, thickness, and structural differences. There are some tests performed to evaluate the performance of materials for specific uses. To evaluate the acoustic performance of the felt, parameters such as sound absorption coefficient and sound transmission loss are considered. In the tests performed using an impedance tube and a reverberation chamber, it was investigated how the properties of the material affected these parameters. The results were that at higher thickness and density, sound absorption generally increased, while sound transmission loss decreased. The findings of the study are an important example for the selection and optimization of acoustic insulation materials and will contribute to the development of more effective insulation solutions in the automotive industry.

Article Effect of Inlet Diameter on the Temperature of Hydrogen Fuel Tanks for Automotive Applications Matthieu Guttinger and Jean-Baptiste R. G. Souppez * Department of Mechanical, Biomedical and Design Engineering, School of Engineering and Technology, College of Engineering and Physical Sciences, Aston University, Birmingham B4 7ET, UK * Correspondence: j.souppez@aston.ac.uk Received: 14 June 2024; Revised: 26 August 2024; Accepted: 29 August 2024; Published: 4 September 2024 Abstract: Contemporary concerns for sustainability have prompted a move away from fossil fuels, with hydrogen being a promising alternative. In the automotive field, Type III hydrogen tanks allow for high pressures to be achieved while being lightweight and small. Their size makes them particularly sensitive to small changes in inlet diameter, which is crucial to ensuring the strict regulatory requirements for internal tank temperatures are met. However, there remains a lack of understanding of the effect of inlet diameter on the internal temperature of Type III hydrogen tanks, needed for the next generation of gaseous hydrogen regulations for land vehicles. Consequently, this paper employs computational fluid dynamics to quantify the effect of the inlet diameter for values ranging from 5 mm to 15 mm on the temperature of Type III hydrogen tanks, of internal diameter 354 mm, to comply with current automotive regulations. Here, we show that (i) an increase in inlet diameter results in a monotonic increase in internal tank temperature; (ii) a linear interpolation between the mass flow rates investigated in this study may be employed to estimate the temperature at a given inlet diameter; and (iii) pre-cooling has an impactful effect and enables control of the internal tank temperature to avoid exceeding regulatory maximum temperature, irrelevant of inlet diameter. Lastly, we provide recommendations on analysing thermal results to ensure the safety of hydrogen tanks by design, with a particular emphasis on temperature hotspots forming upstream of the inlet. These results provide novel insights into the effect of inlet diameter and pre-cooling on the temperature of hydrogen tanks for automotive applications and inform their design to meet relevant regulations inherent to their filling. Moreover, these findings are anticipated to contribute to future regulatory development and the wider adoption of hydrogen as a sustainable fuel.

The automotive sector ranks as the 4th largest contributor to the global economy, accounting for approximately 5% of the world’s Gross Domestic Product (GDP). Additionally, employment in the automotive industry generates a fivefold multiplier effect on job creation in other sectors. This study focuses on the sustainable science, technology, and innovation indicators relevant to Türkiye’s automotive industry, which holds the 7th position in terms of its contribution to the country’s GDP. Drawing on previous research and 33 years of data that reflect the state of Türkiye's automotive sector, as well as its science and technology landscape, this research identifies 10 key indicators that influence the sector’s technological development and innovation capacity. To analyze the similarities and differences among these indicators, a hierarchical cluster analysis (HCA) method was initially employed. Subsequently, a non-hierarchical cluster analysis (NHCA) was conducted to validate the HCA findings. Additionally, multidimensional scaling (MDS) was utilized to assess the similarities and distances among the economic, science, and technology indicators. The formation of 2 clusters was later verified through correlation analysis and factor analysis. The research findings indicate that the R&D and science-related parameters in Türkiye operate in a cohesive manner as anticipated. The percentage changes in the production of automobiles, commercial vehicles, and total domestic output show similar trends, forming a distinct group. In contrast, the indicators for high-technology exports and automotive exports are influenced by different dynamics, displaying separate and unique patterns. Based on these results, the study concludes with recommendations for sector-specific improvement initiatives.

Fuel cell vehicles are aimed to be a new way of environmentally friendly transport. But they face significant problems in terms of costs and infrastructure. Only with demonstration projects and governmental or company subsidies fuel cell vehicles are so far possible. But there is a market for private fuel cell vehicles for personal transport which is viable even without subsidies based on latest current fuel cell technology. It is the niche market of high end fuel cell electric bicycles. Based on latest cost reduction of fuel cell systems and the strong growing market of the high end electric bicycles in Europe, USA and Japan there is a market for fuel cell electric bicycles coming up.

Abstract In this chapter, the authors excavate the long, sometimes troubled evolution of a UNESCO World Heritage List (WHL) nomination in the Marquesas Islands, French Polynesia. The challenges faced by this project over the course of almost three decades illustrate the internal dissonance of two conflicting understandings of heritage, two differing ontologies, and the complicated task of interpreting and protecting Indigenous archaeological resources. While the UNESCO WHL nomination process is deeply rooted in Western perspectives on heritage, preservation, capitalism, and the division of nature and culture, Marquesan views of the past and present draw upon a more fluid, relational understanding of exchange and a material world animated by ancestral spirits and mana that demand respect. The resulting “dissonant heritage” belies a problematic tension between the relationships and aspirations of historic resources that represent both unique value and the promise of a better, more sustainable future. In the face of these challenges, the ultimately successful Marquesas WHL nomination stands as an example of how the strict regulatory, Western structures of UNESCO’s approach to heritage can be challenged to embrace and honor more diverse and indigenous understandings of the world.

Heritage rehabilitation can be a sustainable operation when it succeeds in conveying the intangible, historical, artistic, and symbolic value of the building and, at the same time, to ensure the preservation of soil and material resources. The sustainability of the operation must cover the entire life cycle of the building, starting with the management of materials on the construction site, which allows for an increase in its durability while safeguarding its residual performance. This paper, therefore, outlines a process for the sustainable management of materials at the building redevelopment site using the history of the building and the life cycles of related materials. In particular, the following are explored: residual performance of historical and coeval materials, their endogenous and exogenous reuse of materials in the redevelopment project, the traceability aimed at controlling the supply chain, and the material/component identity card. The latter evolves dynamically, providing useful information for carrying out environmental assessments and monitoring the building’s maintenance cycle. The process is applied to a case study involving the redevelopment of the historical built heritage following the 2009 earthquake that struck the city of L’Aquila and neighbouring territories. The case study demonstrated the validity of the method and at the same time made it possible to introduce an innovative process in the territory, raising awareness among those working in the sector of the value of choices that have environmental and economic advantages.

Species knowledge of local animal species is of great importance for one’s own environmental awareness and is a major component for managing present and future crises in education for sustainable development. For this reason, this study is the first to survey the species knowledge of visitors to the UNESCO Natural World Heritage Site the Wadden Sea of the North Sea, which is the largest mudflat area in the world. In this context, the self-assessment of the respondents and the extent of their connectedness with nature are also examined. To answer the research questions, a questionnaire survey was carried out to determine the species knowledge and degree of connectedness with nature. For data analysis, various statistical methods such as t-tests and correlation analyses were used. The results show that the 126 visitors to the Wadden Sea Visitor Centre have a rather low level of species knowledge. In this regard, the European Herring Gull is the only very well-known species among the respondents. In addition, a further construct was investigated in the form of connectedness with nature, between which a significant positive correlation was found with species knowledge.

This research investigates the intersection of family business practices and cultural heritage management in Malaysia, a country rich in cultural diversity. The study was motivated by the need to understand how family-run businesses contribute to preserving and promoting cultural heritage in Malaysia. Through a qualitative analysis, we examined the business strategies, cultural values, and operational models of family businesses engaged in cultural heritage sectors. Our findings reveal a unique blend of traditional values and modern business understanding, highlighting how these businesses play a crucial role in sustaining cultural heritage. Family businesses in Malaysia have developed distinctive approaches to cultural heritage management, blending traditional values with innovative strategies to navigate the challenges of modernisation and globalisation. This has implications for business practices and cultural preservation, offering insights into sustainable cultural heritage management in a rapidly evolving global landscape. The study underscores the importance of family business-based culture in the stewardship of cultural heritage. It argues for greater recognition of these businesses in policy formulation and heritage management strategies. It shows that Malaysia's symbiotic relationship between family businesses and cultural heritage presents a model that balances economic viability with cultural preservation, offering lessons for the business world and cultural heritage sectors globally.

Nanoscience for the Conservation of Works of Art · 2013
This chapter deals with the general physicochemical properties of works of art materials, strictly correlated to the degradation and alteration processes. The principal chemical and physico-structural properties of both organic and inorganic materials constituting wall paintings and easel paintings are discussed. The mechanisms leading to the degradation of these works of art are analysed, classifying them into three broad categories: natural weathering; pollution – indoor and outdoor; and general chemical, physical and mechanical stresses. The natural weathering of artworks materials is then discussed, focusing on the role of temperature, humidity and light, with particular attention to the phenomenon of salt crystallization. The environmental conditions for the best conservation of indoor and outdoor works of art are highlighted. The remaining chemical effects driving decay processes are analysed by referring to condensation of water, with consequent wetting and capillary suction. In this frame the effects of deliquescent and hygroscopic salts are taken into account, together with the topic of salt efflorescence. Finally, the physical alteration associated with the combined action of light and oxygen from air is treated in relationship to two classes of compounds particularly sensitive to these phenomena, i.e. drying oils and natural varnishes.

This chapter looks into microbial biotechnology in built environments. It explains that the built environment is a microbial habitat providing an abundance of substrates. Microorganisms occur naturally in these habitats and can be introduced by humans. Understanding the complex interactions and activities of microbial communities that cause biodeterioration allows for the development and selection of optimal preservation approaches and technologies. The chapter also explains the impact of microorganisms on our cultural, urban, and industrial heritage. It then presents novel sustainable materials and tools based on microorganisms and the technologies that minimize microbial growth and prevent biodeterioration.

Dedicated to the memory of Arren Bar-Even (19802020), one of the most brilliant biochemists of our times. Living beings are the result of a cocktail made with unknown doses of chance and necessity. Consider a thought experiment, in which we could rewind the ‘tape of life’ starting from the same initial conditions, what biochemical traits and cellular features would finally be the same as those we observe today? It is clear that what is real in biology is a subset of what is possible, and this issue has been discussed at different scales. Thus, structural and dynamic developmental constraints limit the space of solutions for animal bodies (Alberch, 1989), whereas physicochemical restrictions and historical contingencies shape the possible at the molecular level (Jacob, 1981). Meteorite analysis and many organic syntheses performed under prebiotic conditions indicate that the primitive Earth was home of a moderately complicated chemodiversity, including the most common biological building blocks – sugars, fatty acids, amino acids, nucleobases, etc. (Lazcano, 2018). In this period of chemical evolution, physicochemical constraints (i.e. thermodynamics and kinetics in a given environment) determined the origin and maintenance of the abiotic chemical landscape. The chemically possible was the scenario for the organization of the most simple and primitive biochemical systems: autocatalytic cycles for self-maintenance of a set of building blocks, self-reproduction of lipid vesicles, and self-replication of genetic templates (Peret o, 2012). Presumably, all these cycles kicked off in the absence of catalysts or with the involvement of very simple and unspecific facilitators (e.g. mineral surfaces). The emergence of optimizable catalysts through natural selection (e.g. ribozymes) was a phase transition to a period of a more efficient and creative functional screening of the possible (de Duve, 2005). Diverse lines of evidence indicate that metabolic surveys of alternative sources of matter and energy were rapid and explosive, performed by the first microbial communities. Biogeochemical closing of the recycling of bioelements was a vital step for a sustainable and long-term continuity of terrestrial life (Falkowski et al., 2008). Thus, the boundaries of the metabolically possible were expanding in parallel to the coevolution of life and the planet. For instance, after the emergence in some cyanobacterial ancestors of the enzymatic machinery able to extract electrons from water to feed the photoelectronic chain, molecular oxygen accumulated in oceans and afterwards in the atmosphere. Those microorganisms able to cope with this new-to-life compound took advantage of its reactivity and dramatically expanded the world of the metabolically possible: many new metabolites, including steroids, and processes (e.g. oxygen respiration) became available to life. Thus, recurrent patterns in actual cell metabolisms are the result of a long evolutionary exploration within the chemically constrained space of the possible solutions under specific yet changing conditions (de Lorenzo et al., 2014). The beginnings of the scientific study of metabolism focused on model systems (e.g. yeast and skeletal muscle) and well-defined physiological processes (e.g. alcohol fermentation and cellular respiration). Describing chemical transformations in cell-free systems and the use of inhibitors, mutants or isotope labelling helped to draw the first metabolic pathways (Morange, 2020). More recently, functional inference from environmental metagenomes combined with experimental validation (e.g. metabolomics and fluxomics) has expanded the spectrum of known metabolisms, albeit the scrutiny of old model systems still delivers surprises, as for example sulphoglycolysis in Escherichia coli K12 (Denger et al., 2014).

Purpose This study aims to demonstrate the possibility of showing the functionality of complex microbial groups, within ancient structures within a process of refurbishment on a heritage building information modelling (BIM) platform. Design/methodology/approach Both a qualitative and qualitative research method will be used throughout, as observational and scientific results will be obtained and collated. This path being; phenomena – acquisition tools – storage – analysis tools – literature. Using this methodology, one pilot study within the scope of demolition and refurbishment, using suitable methods of collecting and managing data (structural or otherwise), will be used and generated by various software and applications. The principle methods used for the identification of such micro-organisms will incorporate a polymerase chain reaction method (PCR), to amplify DNA and to identify any or all spores present. The BIM/historical BIM (HBIM) process will be used to create a remotely-based survey to obtain and collate data using a laser scanner to produce a three-dimensional point cloud model to evaluate and deduce the condition, make-up and stature of the monument. A documentation management system will be devised to enable the development of plain language questions and an exchange information requirement, to identify such documentation required to enable safe refurbishment and to give health and safety guidance. Four data sampling extractions will be conducted, two for each site, within the research, for each of the periods being assessed, that being the Norman and Tudor areas of the monument. Findings From laboratory PCR analysis, results show a conclusive presence of micro-organism groups and will be represented within a hierarchical classification, from kingdom to species. Originality/value The BIM/HBIM process will highlight results in a graphical form to show data collected, particularly within the PCR application. It will also create standardisation and availability for such data from ancient monuments to make available all data stored, as such analysis becomes substantially important to enable the production of data sets for comparison, from within the framework of this research.

The traditional natural product discovery approach has accessed only a fraction of the chemical diversity in nature. The use of bioinformatic tools to interpret the instructions encoded in microbial biosynthetic genes has the potential to circumvent the existing methodological bottlenecks and greatly expand the scope of discovery. Structural prediction algorithms for nonribosomal peptides (NRPs), the largest family of microbial natural products, lie at the heart of this new approach. To understand the scope and limitation of the existing prediction algorithms, we evaluated their performances on NRP synthetase biosynthetic gene clusters. Our systematic analysis shows that the NRP biosynthetic landscape is uneven. Phenylglycine and its derivatives as a group of NRP building blocks (BBs), for example, have been oversampled, reflecting an extensive historical interest in the glycopeptide antibiotics family. In contrast, the benzoyl BB, including 2,3-dihydroxybenzoate (DHB), has been the most underexplored, hinting at the possibility of a reservoir of as yet unknown DHB containing NRPs with functional roles other than a siderophore. Our results also suggest that there is still vast unexplored biosynthetic diversity in nature, and the analysis presented herein shall help guide and strategize future natural product discovery campaigns. We also discuss possible ways bioinformaticians and biochemists could work together to improve the existing prediction algorithms.

Reductions in nonresidential water demand during the COVID-19 pandemic highlighted the importance of understanding how water age impacts drinking water quality and microbiota in piped distribution systems. Using benchtop model distribution systems, we aimed to characterize the impacts of elevated water age on microbiota in bulk water and pipe wall biofilms. Five replicate constant-flow reactors were fed with municipal chloraminated tap water for 6 months prior to building closures and 7 months after. After building closures, chloramine levels entering the reactors dropped; in the reactor bulk water and biofilms the mean cell counts and ATP concentrations increased over an order of magnitude while the detection of opportunistic pathogens remained low. Water age, and the corresponding physicochemical changes, strongly influenced microbial abundance and community composition. Differential initial microbial colonization also had a lasting influence on microbial communities in each reactor (i.e., historical contingency).

Materials of built heritage are at risk of bio-deterioration caused by diverse populations of microorganisms living in biofilms. The microbial metabolites of these biofilms are responsible for the deterioration of the underlying substratum and may lead to physical weakening and discoloration of stone. Fungal ability in production of pigments and organic acids have crucial role in discoloration and degradation of different types of stone in cultural heritage objects. Additionally, stone objects may support novel communities of microorganism that are active in bio-deterioration process this investigation focused on mycological analyses of microbial biofilm from Mahadev temple, Bastar of Chhattisgarh state which is made of sand stone and which were heavily colonized by fungi. The eight fungal species on sand stone were isolated. Aspergillus sp. was common in stone structure. The identified micro fungi cause discoloration as well as mechanical exfoliation of building stone material that was analyzed through mechanical hyphae penetration and production of dark pigments and organic acids.

Bioweathering crusts are widely distributed on the limestone sculptures of the Longmen Grottoes, a UNESCO World Heritage Site. However, information on microbial communities in this archaeological site is missing. To fill this gap, we identified bacterial communities involved in the formation of bioweathering crusts. The composition analysis showed that Cyanobacteria, Acidobacteria, Chloroflexi, Actinobacteria, Firmicutes, and Planctomycetota are the major components of the bacterial communities in the crusts. Cyanobacteria might be one of the major contributors to the formation of the crusts. A culture-based analysis indicated the presence of bacterial isolates (e.g., Enterobacter sp. and Bacillus sp.) with a potential role in bioprotection. Moreover, five types of biogenic organic acids were detected in the crusts, implying a consequence of organic acid corrosion. Scanning electron microscopy analysis further confirmed microbial penetration into the stone monuments with a biomechanical attack. Our reports provide a microbiological reference for heritage conservators to treat bioweathering crust.

Ancient wooden constructions, also known as wooden cultural relics, refers to ancient wood that has been modified or crafted by human activities. To ensure its preservation, it is crucial to gain further understanding of the decomposition mechanisms affecting archaeological wood. In this study, we investigated the microbiome diversity and cellulose decomposition processes in a 6300-year-old ancient wooden construction at the Tianluoshan site (7000–6300 cal BP) in Zhejiang Province, China. High-throughput sequencing (HTS) was employed to analyze the metagenomic functions, specifically focusing on the microbial communities' cellulose-degrading pathways using bioinformatic approaches. The findings revealed that the excavation of archaeological wood significantly altered the environment, leading to an accelerated deterioration process. This degradation was primarily influenced by carbohydrate metabolism and xenobiotic biodegradation and metabolism pathways within the complex ecosystem consisting of bacteria, archaea, fungi, microfauna, plants, and algae. Proteobacteria, actinobacteria, ascomycota, and basidiomycota were identified as the main sources of bacterial cellulose-degrading enzymes. The results obtained from this evaluation will provide valuable insights for the development of targeted conservation strategies and prioritization of preservation efforts for the ancient wooden constructions found in different regions of the Tianluoshan site.
