Data informed performance assessment and structural health monitoring for existing and historical concrete structures

AbstractOur generation inherits this cultural heritage of historic material and historic reinforced concrete structures and thus bears a certain responsibility to preserve these historic buildings with the help of the new technologies of lifetime management, conservation concepts and the new digitalization as well as the emerging safety concepts of our time. The aim of this article is to analyze the new technologies of data‐based service life management in relation to the assessment of historic reinforced concrete structures and to test the applicability of these methods to these historic buildings.

Interaction of a Dense Layer of Solid Particles with a Shock Wave Propagating in a Tube

A numerical simulation of an unsteady gas flow containing inert solid particles in a shock tube is carried out using the interpenetrating continuum model. The gas and dispersed phases are characterized by governing equations that express the concepts of mass, momentum, and energy conservation as well as an equation that shows the change of the volume fraction of the dispersed phase. Using a Godunov-type approach, the hyperbolic governing equations are solved numerically with an increased order of accuracy. The working section of the shock tube containing air and solid particles of various sizes is considered. The shock wave structure is discussed and computational results provide the spatial and temporal dependencies of the particle concentration and other flow quantities. The numerical simulation results are compared with available experimental and computational data.

What's the story of the elephant? Evaluation of choose‐your‐own‐adventure activities on public perception of human–elephant conflict

AbstractChoose‐your‐own‐adventure (CYOA) narratives offer immersive experiences that can effectively convey complex conservation concepts, fostering empathy and critical thinking, particularly in addressing issues like human–elephant conflict. Despite their potential, there is limited research on the use of CYOA activities in conservation education. In this study, we created an interactive story centered on elephant conservation, drawing from existing research to distill scientific concepts into engaging narratives and utilizing various modes of delivery (YouTube and live performances) to reach diverse audiences. We conducted postactivity surveys to assess variations in audience perception, learning, and conservation engagement intentions in relation to sociodemographic factors, activity type, and messages encountered. We then modeled the relationships between ordinal responses and explanatory variables using cumulative ordinal mixed models (N = 398). For the YouTube version, we also considered sociodemographic factors (YouTube n = 53, non‐YouTube n = 47). Our findings indicate a preference for live performances over online YouTube activity, with participants gaining knowledge about elephant conservation from both formats. For the YouTube activity, participants strongly agreed that the activity allowed engagement with the character and topic. They also expressed a higher likelihood of participating in several conservation actions, relative to a control group. While CYOA storytelling shows promise for conservation education, challenges remain in simplifying scientific language, assessing its impact on comprehension of complex issues, standardizing outcomes, and effectively communicating knowledge. Further research is recommended to adapt this approach, making it applicable to various audiences and domains beyond conservation.

Spreading the “scientific approach”: the chemical turn in conservation from the Musée d’ethnographie du Trocadéro to colonial museums in the French empire

ABSTRACT This text retraces the installation of the laboratory in the Musée d’ethnographie du Trocadéro in the 1930s. It questions the ambitions that lay behind the “scientific” conception of museum conservation as promoted by the museum’s technical assistant, Adrien Fédorovsky, in parallel with many other European museums. Particular attention is paid to chemical methods of conservation and the setting up of toxic chambers. The products used and their suppliers are documented, and overlaps with other social fields sketched out. Finally, the text traces the spread of chemical conservation methods to planned and completed museums in the French empire.

CO2 Loss into Solution: An Experimental Investigation of CO2 Electrolysis with a Membrane Electrode Assembly Cell.

In pursuit of commercial viability for carbon dioxide (CO2) electrolysis, this study investigates the operational challenges associated with membrane electrode assembly (MEA)-type CO2 electrolyzers, with a focus on CO2 loss into the solution phase through bicarbonate (HCO3 -) and carbonate (CO3 2-) ion formation. Utilizing a silver electrode known for selectively facilitating CO2 to CO conversion, the molar production of CO2, CO, and H2 is measured across a range of current densities from 0 to 600 mA/cm2, while maintaining a constant CO2 inlet flow rate of 58 mL/min. The dynamics of CO2 loss are monitored through measurements of pH changes in the electrolyte and carbon elemental balance analysis. Employing the concept of conservation of elemental carbon, a chemical reaction analysis is conducted, identifying the critical role of the hydroxide (OH-) ion. At lower current densities below 125 mA/cm2, where CO2 reduction predominates, it is observed that CO2 loss is proportional to current density, reaching up to 0.18 mmol/min, and directly correlates with the rate of OH- ion production, indicative of HCO3 -/CO3 2- ion formation. Conversely, at higher current densities above 450 mA/cm2, where hydrogen evolution is the dominant process, CO2 loss is shown to decouple from the OH- ion production rate with a constant limit condition of 0.12 mmol/min, regardless of the current density. This suggests that electrolyte-induced cathode flooding restricts CO2 access to cathode sites. Additionally, pH change in the electrolyte during the electrolysis further infers differing ion populations in the CO2 reduction and hydrogen evolution regimes, and their movement across the membrane. Continued monitoring of the pH change after the cessation of electricity offers insights into the accumulation of HCO3 -/CO3 2- ion at the cathode, influencing salt formation.

Environmental Conservation in Quraish Shihab and Hamka’s Perspective

The environmental crisis has become a global issue and a common concern of this century. The anthropocentric paradigm is also one of the causes of environmental damage. This paradigm assumes that the center of the universe is human beings, so they are free to exploit natural resources for their interests. This paper will reveal Qur'an-based environmental conservation. The author more specifically reveals the views of the mufasir of Indonesia, M. Quraish Shihab and Buya Hamka, on the issue of environmental conservation. This paper aims to find the concept of environmental conservation based on the Qur'an by two Indonesian muftis. The research method used in this article is qualitative and is library research. The main data used in this article include Tafsir Al-Misbah by M. Quraish Shihab and Tafsir Al-Azhar by Hamka. The data were analyzed with a content analysis approach. The conclusion of this article shows that Indonesia's mufasir is concerned about environmental conservation based on the Qur'an. M. Quraish Shihab and Buya Hamka have a common interpretation that the universe was created by Allah for humans and used to meet their needs proportionally. The concept of the caliph and its implementation (utilizing, maintaining, preserving, and regenerating nature for the next life) is urgently needed to protect the earth and its environment. Environmental preservation is contained in the concept of iḥsān with the peak of good behavior towards nature. The concept of justice by acting in balance is a responsibility to the environment. The concept of proportionality (not excessive) in the use of the environment.

Medical metaphors in the conservation discourse: insights from critical metaphor analysis

This article explores the use of medical metaphors in conservation discourse, analysing their impact on shaping the concept of conservation through the lens of cognitive linguistics and sociology. Through analysis of 120 papers from the ICOM-CC Theory, History and Ethics Working Group, metaphors such as the conservation object is a human being and the conservator is a doctor were identified. The study reveals how these metaphors frame conservation as a beneficent act of caring for an object, akin to medical treatment. However, it also highlights limitations in explaining stakeholder involvement and community autonomy, the stages of conservation actions, and more nuanced concepts of damage. While this article does not argue against the use of medical metaphors in conservation, it aims to raise awareness of those limitations deriving from the use of complex and fluid concepts in both fields. In conclusion, this study advocates for further research to explore culture-specific features and chronological changes in the use of metaphors to promote a deeper understanding of cross-cultural and inter-generational communications in conservation.

Soviet museum ethnography at the VII International Congress of Anthropological and Ethnographic Sciences: restoration and conservation of disciplinary heritage under the “gaze” of the West

(1964) is considered in the article as a discussion space within which ethnographers and museum workers presented and debated different views on the past and present of their discipline. Archival materials are explored through the concepts of restoration and conservation – rhetorical strategies that involve different forms of interpretation of disciplinary heritage and projects for action. Projects for the “revival” of the Museum of the Peoples of the USSR in Moscow and “Materials on Ethnography’s” edition in Leningrad mostly referred to the ethnography of the 1920s, which was suppressed and criticized during the transition to Marxist methodology in the 1930s. The restoration strategy led to the recognition of the unspoken lag behind Western anthropology and museum affairs. The reconstruction of fragments of the past was proposed as a solution to the problem. The conservation strategy, on the contrary, saw Soviet museum ethnography as ahead of foreign ones. The legacy of the “marxization” of the 1930s, according to this rhetoric, was the key to victories in the past and present, and its criticism and rejection deprived Soviet ethnography of its advantages. Museum practices of research and representation of the culture and life of collective farmers and workers, and the active use of mannequins and life-size dioramas to show social relations were recognized as such a positive legacy.

Interactions among lump optical solitons for coupled nonlinear Schrödinger equation with variable coefficient via bilinear method

In this paper, a non-autonomous (3+1) dimensional coupled nonlinear Schrödinger equation (NLSE) with variable coefficients in optical fiber communication is analyzed. By means of bilinear technique and symbolic computations, new multi-soliton solutions of the coupled model in different trigonometric and lump functions are given. Then, in terms of perturbed waves, considering the steady state solution and the small perturbation on the three directions x, y, z and the time t, the soliton transmission are also considered. The behaviour of interaction among lump periodic soliton is studied and optical soliton solutions are reached. This study has certain significance for the analysis of other nonlinear dispersion systems and the application of optical physics. The results are presented through graphs generated by using Maple. The important feature of the proposed study is to show different behaviour of the soliton at each component. The behaviour of solitons, their interactions, and their transformations are all governed by the fundamental concept of energy conservation in all three examples. We demonstrate the efficiency of our suggested methodology for analyzing the NLSE equations using the numerical simulations and analytical tools, yielding fresh insights into their behaviour and solutions. Our findings help to develop mathematical tools for investigating nonlinear partial differential equation (NLPDEs) and provide new insights on the dynamics of NLSE equations, which have implications for many domains of physics and applied mathematics

Novel hybrid waves solutions of Sawada–Kotera like integrable model arising in fluid mechanics

The purpose of the paper is to uncover more advanced soliton solutions for the three-component Sawada–Kotera (SK)-like equation. The Hirota bilinear (HB) method is exploited to obtain a bilinear form and general solution to the three-component SK like equation. The study explores various soliton solutions by considering multiple dispersion coefficients. The focus is on multiple bifurcated solitons, hybrid breathers, periodic lumps, and periodic rogue waves, as well as the resonance in soliton solutions. The fission or fusion processes of solitons are analyzed for specific values of parameters. From the literature, real Y-shaped and X-shaped solitons in water waves are provided. The results are presented through graphs generated using MATLAB 2021. The important feature of the proposed study is to show different behavior of the soliton in each component. The behavior of solitons, their interactions, and their transformations are all governed by the fundamental concept of energy conservation in all three cases. The amplitudes and forms of the solitons are impacted by the energy redistribution that occurs during collisions, fission, or other interactions. Understanding these energy dynamics aids in predicting how these nonlinear wave events would behave in complex systems and sheds light on the fundamental physics of these phenomena.

Revising the Keystone Species Concept for Conservation: Value Neutrality and Non-Nativeness

ABSTRACT The keystone species concept is often used in conservation. However, scientists and conservationists use the concept in many different ways. I suggest that a problem with the concept in conservation is not the lack of a shared definition. Instead, the problem is how the concept is applied to only certain species despite potentially covering a broader suite of species. This highlights unstated values in using the concept in conservation. I use novel examples, such as non-native Burmese pythons in Florida, to motivate this. I argue that the concept should include these species and be used value-neutral.

Traditional knowledge, attitude and behaviour of indigenous people towards endangered wildlife conservation in Kon Plong District, Vietnam

Indigenous knowledge, attitudes, and perceptions of local people are very important concepts for wildlife conservation. Endangered wildlife species that live in Kon Plong forests have been under pressure from the communities living around them, including wildlife hunting, trapping, capturing, illegal logging, and encroachment for residential and production land. This study aims to understand the knowledge, attitude, and behaviour of indigenous people towards endangered wildlife in order to protect these species. Some participatory rural appraisal tools were used to discuss the situation and collect information in nine villages of four communes in Kon Plong District from December 2019 to March 2020. The results showed that the levels of knowledge about endangered wildlife among indigenous people in communes were statistically different. People’s knowledge of the law influenced their behaviour. Gender had the greatest influence on the level of knowledge. Most indigenous people had a positive attitude and wanted to protect endangered animals. “Commune” and “culture” were the two factors affecting people’s attitudes. “Commune”, “culture”, and the level of understanding affected the hunting behaviour of people. Negative human impacts have seriously influenced endangered wildlife species. Therefore, it is necessary to develop a long-term conservation strategy and plan, including the establishment of Kon Plong Special-Use Forests, supporting livelihoods for local people, communicating, and raising awareness among local people, and increasing the participation of community organisations.

Scale analysis of undercut and bulge driven by thermocapillary convection due to surface-active solute on a solidified surface

This study scales the shape of the undercut, a depression region near the triple-phase line parallel to the scanning direction, and the bulge in the central region within the fusion zone, considering thermocapillary convection affected by a surface-active solute in the molten pool for the first time. Undercuts, commonly encountered in welding, additive manufacturing, and re-solidification processes, reduce fatigue and fracture strength while enhancing stress concentration. Utilizing the interfacial Young–Laplace equation and Bernoulli equations in the shear layer driven by thermocapillary force influenced by the surface-active solute-affected critical temperature, and introducing the concept of mass conservation, the scale analysis finds that the undercut depth and bulge height increase as Marangoni and Prandtl numbers increase, and the loss coefficient decreases. Furthermore, the widths of the undercut and bulge exhibit increases with dimensionless beam power, fusion zone width, and the ratio of solid-to-liquid thermal conductivity. The COMSOL Multiphase code is also used for simulation and successful comparison, aligning with experimental data from laser polishing. This analysis aids in understanding and controlling microstructures in various processes beyond laser polishing.

Cultural Development on Peranakan Chinese a Thematic Review

The Peranakan Chinese culture is a unique sample of multicultural amalgamation, and its intricate nature has spurred scholarly discussions for decades. As modern society evolves, opportunities and challenges arise for its cultural conservation. Nevertheless, However, there is a distinct lack of comprehensive review on this subject globally. To address this gap, utilizing the ATLAS. ti 23 software, this paper undertakes a thematic review of 30 articles related to Peranakan Chinese culture published between 2018 and August 2023. Through thematic analysis, five core themes emerge: Cultural Identity, Cultural Conservation, History and Society, Tangible and Intangible Cultural Heritage, and Cultural Dissemination. While diversity is widely recognised as a hallmark of Peranakan Chinese culture, this study sheds further light on the nuances and complexities of cultural integration due to geographic, historical and social factors. The review observes that current research predominantly validates past perspectives on cultural identity by examining various cultural mediums across different branches. However, there is a gradual shift towards sustainable cultural development. Moreover, the study underscores the significance of exploring new technologies and concepts for cultural conservation. This research offers direction for researchers interested in Peranakan Chinese and provides insights for deeper investigations into the subject.

Dwelling architecture in the context of socio-economic and technological conditions of modern Kazakhstan (on the example of Almaty city)

The relevance of this research is highlighted by Almaty’s continuing status as a historical and cultural centre and a financially independent city, despite no longer serving as the capital of the Republic of Kazakhstan. Currently, an important issue is the formation of the “Smart City” plan in the context of modern concepts of resource conservation and environmental policy. The research aims to substantiate changes in the formation of housing architecture under the influence of socio-economic, political, and technological processes in the context of gradual historical changes in the example of Almaty, as well as to determine the priority directions of development of urban planning processes, in particular on the territory of the residential zone. The following methods of scientific research were used: abstract-logical method; comparative method; historical method; method of system analysis and synthesis. To achieve the research aims, the elements of the socio-economic development of Almaty in the context of historical, cultural, and educational centres were defined. The peculiarities of dwelling architecture from the 1920s to the present day are analysed. This research proposes priority directions for urban planning in Almaty’s residential area by analysing historical architecture influenced by socio-economic and technological factors.

Cryopreservation of Potamotrygon Stingrays’ Semen: Enhancing One Conservation Effort

This pioneering study aimed to evaluate the cryopreservation of semen from P. falkneri (n = 4) and P. motoro (n = 4), maintained ex situ at the Sao Paulo Aquarium, Brazil. For this purpose, the animals were physically restrained, biometric data of the disc and clasper were obtained, and semen was collected through manual massage. Total motility and progressive motility parameters were evaluated using Computer-Assisted Sperm Analysis (CASA) with IVOS II equipment and Animal Breeders II software. The semen extenders INRA 96 and OptiXcell were used to assess their efficacy in sperm cryopreservation. INRA required the addition of 5% dimethyl sulfoxide (DMSO) as a cryoprotectant. The results indicated that there was no difference in semen motility values before and after freezing with INRA + DMSO (p = 0.6226). On the other hand, samples cryopreserved with OptiXcell showed a difference in semen motility post-thaw (p = 0.0156). These findings contribute to a broader study on optimizing cryopreservation protocols to ensure long-term viability and fertility of semen, enhancing genetic diversity and supporting wild population restoration. A multidisciplinary approach integrating reproductive biology, ecology, physiology, and assisted reproduction technologies, aligned with the One Conservation concept, is essential for advancing conservation and management strategies for these threatened species.

Landholder perceptions and attitudes towards the rewilding of private land: an analysis from Surrey, UK

ABSTRACT Rewilding is a conservation concept and practice which has gained traction over the past two decades, and is often perceived as a powerful tool to reverse anthropogenic ecological degradation. In the UK, Environmental Land Management Schemes (ELMS) have introduced the idea of ‘public money for public goods’, making some rewilding initiatives more viable for landholders. Many conservation organisations work with landholders to promote rewilding as part of local conservation strategies, but there remains a lack of understanding of landholder perceptions and attitudes towards rewilding. This research used semi-structured interviews based on the gaps identified in the literature to explore these aspects in a sample population of 8 landholders in Surrey, UK. Thematic analysis interpreted the importance of emergent patterns and implications in relation to existing literature. This research found that landholders associate many different meanings towards rewilding. These perceptions fall along two spectra, ranging from passive to active forms of rewilding and with different levels of impact on human activities. Landholder valuations of rewilding are profoundly influenced by their perceptions of its meaning, with more favourable attitudes expressed towards ‘low-impact’, active forms of rewilding. Concern was expressed about the need to balance rewilding goals with food security. This emphasises that understanding local views is essential to improve consideration of practical constraints, whilst helping to reduce polarisation and mistrust about rewilding. Conservation organisations should facilitate collaboration among landholders to kickstart the implementation of acceptable and context-specific forms of rewilding, playing a key role in achieving local and national nature recovery targets.
