Green Emotion: Incorporating Emotional Perception in Green Marketing to Increase Green Furniture Purchase Intentions
Authors: Yu Shulan , Zhong Zhen , Zhu Yalin , Sun Jing
Published: June 2024

The industrialization process has led to environmental deterioration, which has created challenges for sustainable development. However, there is an increasing inclination to purchase green furniture as a sustainable form of furniture. Hence, investigating the determinants of consumers’ intention to purchase green furniture is beneficial for promoting the adoption of sustainable furniture. Previous research has examined the functional aspects of purchasing behavior using the theory of planned behavior (TPB), while giving less consideration to affective elements. This study aimed to investigate the factors that influence the intention of future users to purchase green furniture, explicitly focusing on emotional perception. This study utilized the PAD three-dimensional emotion model. A novel conceptual model was developed, drawing upon the findings of the literature review. This study employed the questionnaire method to collect data, resulting in 412 valid samples. The collected data were then analyzed and processed using partial least squares structural equation modeling (PLS-SEM) in SmartPLS 3.0 software. Additionally, the mediating influence of the variables was examined using the bootstrap method. The results suggested that the perceived pleasure, arousal, and dominance all had a substantial influence on the beneficial effect of green furniture elements on purchase intention. Among these factors, pleasure (PP) had the strongest mediating effect on the relationship between green brand image (GBI) and purchase intention (PI). Arousal (PA) had the strongest mediating effect on the relationship between eco-innovation (EI) and purchase intention (PI). Dominance (PD) had the strongest mediating effect on the relationship between purchase customization (PC) and purchase intention (PI). Furthermore, this paper examined the disparities between the characteristics of green furniture and conventional furniture in terms of their ability to stimulate emotional responses and influence consumers’ intention to purchase. This study revealed that green features (GF) have a greater capacity to evoke emotional responses in consumers, consequently impacting their intention to purchase green furniture. The study’s findings have both theoretical implications and practical relevance. In theory, these findings enhance the theoretical framework of purchase intention for green furniture. In practice, they provide specific ideas and recommendations for green furniture companies to develop emotional marketing strategies.
Flexibility Value of Multimodal Hydrogen Energy Utilization in Electric–Hydrogen–Thermal Systems

Published: June 2024

Hydrogen energy is now a crucial technological option for decarbonizing energy systems. Comprehensive utilization is a typical mode of hydrogen energy deployment, leveraging its excellent conversion capabilities. Hydrogen is often used in combination with electrical and thermal energy. However, current hydrogen utilization modes are relatively singular, resulting in low energy utilization efficiency and high wind curtailment rates. To improve energy utilization efficiency and promote the development of hydrogen energy, we discuss three utilization modes of hydrogen energy, including hydrogen storage, integration into a fuel cell and gas turbine hybrid power generation system, and hydrogen methanation. We propose a hydrogen energy system with multimodal utilization and integrate it into an electrolytic hydrogen–thermal integrated energy system (EHT-IES). A mixed-integer linear programming (MILP) optimization scheduling model for the EHT-IES is developed and solved using the Cplex solver to improve the operational feasibility of the EHT-IES, focusing on minimizing economic costs and reducing wind curtailment rates. Case studies in northwest China verify the effectiveness of the proposed model. By comparing various utilization modes, energy storage methods, and scenarios, this study demonstrated that integrating a hydrogen energy system with multimodal utilization into the EHT-IES offers significant technical benefits. It enhances energy utilization efficiency and promotes the absorption of wind energy, thereby increasing the flexibility of the EHT-IES.
How Military Executives Shape Digital Transformation of Firms—The Moderating Role of Symbiosis Orientation and Market Power
Authors: Wang Yaping , Zhang Mengting
Published: June 2024

The requirement of sustainable development has led to challenges for DTF (i.e., digital transformation of firms). Extensive studies have been conducted on how the personality traits of executives influence the behavior of firms. However, the effect of military experience on DTF has yet to be determined. This concern is addressed in this study from the imprinting theory (IT) and upper echelons theory (UET) perspectives. We aim to investigate whether and how military executives impact DTF. Analysis of data from listed firms in China between 2010 and 2020 indicates that military executives positively enhance DTF. This research also evaluates the moderating effects of symbiosis orientation and the market power of firms on the above relationship. Heterogeneity analysis reveals that the impact of executives’ military experience on DTF is only significant in non-regulated, high-technology, and low-pollution industries. Our findings expand the literature on leadership and DTF. We introduce the concept of symbiosis orientation and examine the moderating roles of symbiosis orientation and market power in the above effect, which elucidates the interplay between organizations and the external environment. Our findings provide insights into enhancing digital transformation efforts by strategically selecting suitable military leadership for firms and further promoting the sustainable development of firms.
Effects of Rodent Isolation on Plant Community Structure and Greenhouse Gas Emission in the Alpine Grassland of the Qinghai–Tibet Plateau
Authors: Wu Hongbao , Chen Ya , Ganjurjav Hasbagan , Zhao Jianrong
Published: June 2024

As one of the dominant species of the alpine grassland on the Qinghai–Tibet Plateau, the activities (e.g., gnawing, burrowing, and grass storage) of plateau pikas (Ochotona curzoniae) directly alter the plant community structure of the grassland ecosystem and affect livestock production and greenhouse gas emission. In order to investigate the effects of rodent isolation (RI) on plant community structure and greenhouse gas emission in the alpine grassland of the Qinghai–Tibet Plateau, we established plots of rodent isolation and rodent activity (i.e., the control sample (CK)) in the 14th village, Seni District, Nagqu City in May 2018. From July 2019 to September, the numbers, sizes, and total damaged area of effective holes; the height, coverage, and aboveground plant biomass; and the methane (CH4) and nitrous oxide (N2O) emissions of the alpine grassland were monitored by the quadrat survey method and static closed-chamber method. The results show that the invasion and tunneling of Ochotona curzoniae resulted in the destruction of alpine grassland measuring 0.064 m2 per square meter, while the rodent isolation plots showed that 97.9% of the alpine grassland remained unaltered; such unaffected land implies that the economic income of herdsmen could increase by 140 CNY hm−2. The rodent isolation plots also show that the height and proportion of grasses and sedges in the alpine grassland increased, while the proportion of poisonous weeds decreased. Moreover, the rodent isolation plots also showed a significantly increased coverage of aboveground biomass (p < 0.05), although species richness showed no significant effect based on the Shannon–Weiner, Simpson, and Pielou indices (p > 0.05). The soil uptake of CH4 and N2O was 204.99 ± 50.23 μg m−2 h−1 and 4.48 ± 1.02 μg m−2 h−1 in the rodent isolation plots, significantly higher by 465.75% and 3001.4% relative to the rodent activity plots, respectively (p < 0.05). Therefore, the establishment of rodent isolation areas can effectively alleviate the degree of damage to alpine grasslands in the short run and slow down the greenhouse gas emission rate to some extent. However, excessive rodent control may also have negative effects on grassland ecosystems, so more attention should be paid in future studies to determining the disturbance threshold of plateau pika in this area. These results provide theoretical guidance for rodent control, grassland protection, and ecological environment management on the Qinghai–Tibet Plateau.
A Study on the Coupling Coordination of Urban Resilience and the Tourism Economy in the Beijing–Tianjin–Hebei Region
Authors: Zhang Ying , Li Yunyan
Published: June 2024

The high-quality economic growth of tourism is intimately related to a city’s overall strength, and urban resilience is an important index to measure the comprehensive strength of a city. Therefore, determining how to enhance the construction of urban resilience, improve the quality of tourism development, and promote the coupling coordination of these two systems has attracted academic attention in recent years. Based on the panel data of 13 cities in the Beijing–Tianjin–Hebei region from 2010 to 2021, an entropy weight method, coupling coordination model, and obstacle degree model were used to analyze the coupling coordination degree, spatiotemporal evolution characteristics, and obstacle factors between urban resilience and the tourism economy. The results show the following: (1) Urban resilience and tourist economic development levels in the Beijing–Tianjin–Hebei region show an overall upward trend, and both of them show obvious spatial differences. (2) The coupling coordination degree of urban resilience and the tourism economy shows a trend of first rising and then declining in the temporal dimension, while it shows a spatial differentiation pattern of “high in the middle and low in the surrounding area” in the spatial dimension. (3) The obstacle degree structure of the coupling coordination of urban resilience and the tourism economy in the Beijing–Tianjin–Hebei region is relatively stable, with economic resilience as the leading obstacle in the urban resilience system and tourist economic development benefits as the leading obstacle in the tourism economy system. In the future, the Beijing–Tianjin–Hebei region needs to strengthen regional cooperation, enhance the driving role of central cities, continuously improve urban resilience, and promote the high-quality development of the tourism economy.
Comparisons of Driving Characteristics between Electric and Diesel-Powered Bus Operations along Identical Bus Routes
Authors: Ng Ka-Wai , Tong Hing-Yan
Published: June 2024

The energy consumption profiles of conventional fuelled and electric vehicles are different due to the fundamental differences in the driving characteristics of these vehicles, which have been actively researched elsewhere but mostly on the basis of uncommon geographical contexts. This study, therefore, collected driving data on electric and conventional diesel buses running along exactly the same set of bus routes in Hong Kong during normal daily revenue operations. This enabled a fair comparison of driving characteristics for both types of bus under identical real-life, on-road driving conditions, which highlighted the originality and contributions of this study. A three-step approach was adopted to carry out detailed driving pattern analyses, which included key driving parameters, speed–acceleration probability distributions (SAPDs), and vehicle-specific power (VSP) distributions. Results found that route-based comparisons did highlight important differences in driving patterns between electric and diesel buses that might have been smoothed out by analyses with mixed-route datasets. In particular, the spread, intensity, and directions of these differences were found to be exaggerated at the route-based level. The differences in driving patterns varied across different routes, which has significant implications on vehicle energy consumption. Government agencies and/or bus operators should make references to these results in formulating electric bus deployment plans.
Beyond Multidimensional Vulnerability Approach: A Triple Network Notion for Urban Cohesion in At-Risk Neighborhoods of Jaen’s Historic Center
Authors: Rivas-Navarro Juan L. , Bravo-Rodríguez Belén
Published: June 2024

Today’s cities need more than ever methodological devices that ensure a specific urbanism, in keeping with the complexity of relationships that occur in the urban space. Networks or systems of a diverse nature must be activated to achieve a certain success of the city, even more so in its fragile central fabric. This study is focused on the historic neighborhoods of the city of Jaén (Spain), which have a high vulnerability index. The aim is to establish a strategy to revitalize their urban and social capital and improve their articulation with the rest of the urban and territorial structure. A methodological proposal for the analysis of vulnerability factors and an urban and cartographic analysis of the public space is addressed through an interweaving of a triple network: environmental, social, and urban. For this purpose, the configuration of this overlapping network of analysis and the formulation of criteria is presented, which considers the urban multiplicity and promotes new dynamics for the integrated urban regeneration of the area and for the activation of public and collective urban spaces.

Published: June 2024

The paradigm of sustainable energy is gaining ground at the historical juncture of the present worldwide push for sustainable development. This is being driven by the latest technological advancements and by a maturing process of public policy evolution toward support for a sustainable energy transition. This paper analyzes, with the support of bibliometric analysis, the specialized literature in order to capture the main themes of interest, as well as their evolution, thus offering a panoramic view of research trends and the significance of implementing correct environmental measures and policies. Covering the period from 1991 to 2024, our exploration filters 2990 articles from the Web of Science database using a query that intersects “sustainable energy”, “renewable energy”, and “sustainable development”, with a nuanced consideration of the political landscape that shapes these domains. Using the advanced capabilities of the R program, the methodology employed facilitates a nuanced workflow of extraction and analysis, allowing for a detailed examination of the proliferation of research over the decades. This paper provides significant results, demonstrating the increasing impact of research through international collaborations, the importance of high-impact journals on sustainability policies, and the growing focus on “renewable energy” and “CO2 emissions”. The analysis of the relevance of term groups in environmental policy development and the correlation between economic growth and CO2 emissions confirms emerging trends. Furthermore, critical directions for future research and the necessity for formulating and implementing coherent sustainability policies are highlighted.

Published: June 2024

In the present paper, we consider an effective computational method to analyze a coupled dynamical system with Caputo–Fabrizio fractional derivative. The method is based on expanding the approximate solution into a symmetry Haar wavelet basis. The Haar wavelet coefficients are obtained by using the collocation points to solve an algebraic system of equations in mathematical physics. The error analysis of this method is characterized by a good convergence rate. Finally, some numerical examples are presented to prove the accuracy and effectiveness of this method.
A Modular Robotic Arm Configuration Design Method Based on Double DQN with Prioritized Experience Replay
Authors: Ding Ziyan , Tang Haijun , Wan Haiying , Zhang Chengxi , Sun Ran
Published: June 2024

The modular robotic arms can achieve desired performances in different scenarios through the combination of various modules, and concurrently hold the potential to exhibit geometric symmetry and uniform mass symmetry. Therefore, selecting the appropriate combination of modules is crucial for realizing the functions of the robotic arm and ensuring the elegance of the system. To this end, this paper proposes a double deep Q-network (DDQN)-based configuration design algorithm for modular robotic arms, which aims to find the optimal configuration under different tasks. First, a library of small modules of collaborative robotic arms consisting of multiple tandem robotic arms is constructed. These modules are described in a standard format that can be directly imported into the software for simulation, providing greater convenience and flexibility in the development of modular robotic arms. Subsequently, the DDQN design framework for module selection is established to obtain the optimal robotic arm configuration. The proposed method could deal with the overestimation problem in the traditional deep Q-network (DQN) method and improve the estimation accuracy of the value function for each module. In addition, the experience replay mechanism is improved based on the SumTree technique, which enables the algorithm to make effective use of historical experience and prevents the algorithm from falling into local optimal solutions. Finally, comparative experiments are carried out on the PyBullet simulation platform to verify the effectiveness and superiority of the configuration design method developed in the paper. The simulation results show that the proposed DDQN-based method with experience replay mechanism has higher search efficiency and accuracy compared to the traditional DQN scheme.
A Bridge between Trace Anomalies and Deconfinement Phase Transitions
Authors: Sheng Bing-Kai , Ma Yong-Liang
Published: June 2024

Inspired by the fact that both the dilaton potential encoding the trace anomalies of QCD and the Polyakov loop potential measuring the deconfinement phase transition can be expressed in the logarithmic forms, as well as the fact that the scale symmetry is expected to be restoring and colors are deconfined in extreme conditions such as high temperatures and/or densities, we conjecture a relation between the dilaton potential and the Polyakov loop potential. Explicitly, we start from the Coleman–Weinberg type potential of a real scalar field—a dilaton or conformal compensator—and make an ansatz of the relation between this scalar field and the Polyakov loop to obtain the Polyakov loop potential, which can be parameterized in Lattice QCD (LQCD) in the pure glue sector. We find that the coefficients of Polyakov potential fitted from Lattice data are automatically satisfied in this ansatz, the locations of deconfinement and scale restoration are locked to each other, and the first-order phase transition can be realized. Extensions to the low-energy effective quark models are also discussed. The conjectured relation may deepen our understanding of the evolution of the universe, the mechanism of electroweak symmetry breaking, the phase diagram of QCD matter, and the properties of neutron stars.
Temporal Dynamics and Influential Factors of Taste and Odor Compounds in the Eastern Drinking Water Source of Chaohu Lake, China: A Comparative Analysis of Global Freshwaters
Authors: Shang Lixia , Ke Fan , Xu Xiangen , Feng Muhua , Li Wenchao
Published: June 2024

The escalating proliferation of cyanobacteria poses significant taste and odor (T/O) challenges, impacting freshwater ecosystems, public health, and water treatment costs. We examined monthly variations in four T/O compounds from September 2011 to August 2012 in Chaohu Lake’s eastern drinking water source (DECL). More importantly, we compared the reported T/O occurrence and the related factors in freshwater bodies worldwide. The assessment of T/O issues indicated a severe and widespread problem, with many cases surpassing odor threshold values. Remarkably, China reported the highest frequency and severity of odor-related problems. A temporal analysis revealed variations in odor occurrences within the same water body across different years, emphasizing the need to consider high values in all seasons for water safety. Globally, T/O issues were widespread, demanding attention to variations within the same water body and across different layers. Algae were crucial contributors to odor compounds, necessitating targeted interventions due to diverse odorant sources and properties. A correlation analysis alone lacked definitive answers, emphasizing the essential role of further validation, such as algae isolation. Nutrients are likely to have influenced the T/O, as GSM and MIB correlated positively with nitrate and ammonia nitrogen in DECL, resulting in proposed control recommendations. This study offers recommendations for freshwater ecosystem management and serves as a foundation for future research and management strategies to address T/O challenges.

Published: June 2024

We encountered a case of mushroom intoxication complicated by “toxic-like” myocarditis. Because of the lack of systematized knowledge on this subject, we performed a systematic review of the literature on cardiac toxicity in mushroom poisoning (MP). The aim of this study was to identify and describe the severity, the causal relationship, and the mushroom species involved in other reported cardiac events associated with MP. We included 39 studies in our review. We found 106 cases of cardiac events associated with MP, including 18 deaths. A wide variety of cardiac manifestations were reported, ranging from the simple elevation of cardiac enzymes (n = 61) to ventricular tachycardia (n = 14), acute heart failure (n = 18), and myocarditis (n = 7). Causal relationship between cardiac manifestations and mushroom poisoning was assessed for 42 patients, applying the algorithm validated by the French Toxicovigilance Coordination Committee. Twenty-three cases (54.8%) had a “possible” causal relationship, eight cases (19%) a “probable” relationship, and ten cases (23.8%) a “very probable” relationship. Several fungal genera were involved in reported cases, including Amanita but also rarer ones like Russula and Tricholoma. In conclusion, we showed that cases of cardiac toxicity following MP have been documented in the existing literature, and for some of them, we assessed a strong causal relationship.

Published: June 2024

The study involved five ferrets from one household in Poland, comprising three sick 9-week-old juveniles, their healthy mother, and another clinically normal adult, admitted to the veterinary clinic in June 2023. The juvenile ferrets displayed significant lethargy and a pronounced unwillingness to move with accompanying pulmonary distress. Prompted by concurrent outbreaks of A/H5N1 influenza virus infections in Polish cats, point-of-care tests were conducted that revealed type A influenza antigens in the throat swabs of all five ferrets. Despite treatment, one juvenile ferret exhibited dyspnea and neurological symptoms and eventually died. The two remaining ferrets recovered fully, including one severely affected showing persistent dyspnea and incoordination without fever that recovered after 11 days of treatment. In the RT-qPCR, the throat swabs collected from all surviving ferrets as well as the samples of lungs, trachea, heart, brain, pancreas, liver, and intestine of the succumbed ferret were found positive for A/H5N1 virus RNA. To our best knowledge, this is the first documented natural A/H5N1 avian influenza in domestic ferrets kept as pets. In addition, this outbreak suggests the possibility of asymptomatic A/H5N1 virus shedding by ferrets, highlighting their zoonotic potential and the advisability of excluding fresh or frozen poultry from their diet to reduce the A/H5N1 virus transmission risks.
Interferon-Stimulated Genes that Target Retrovirus Translation
Authors: Jäger Niklas , Pöhlmann Stefan , Rodnina Marina V. , Ayyub Shreya Ahana
Published: June 2024

The innate immune system, particularly the interferon (IFN) system, constitutes the initial line of defense against viral infections. IFN signaling induces the expression of interferon-stimulated genes (ISGs), and their products frequently restrict viral infection. Retroviruses like the human immunodeficiency viruses and the human T-lymphotropic viruses cause severe human diseases and are targeted by ISG-encoded proteins. Here, we discuss ISGs that inhibit the translation of retroviral mRNAs and thereby retrovirus propagation. The Schlafen proteins degrade cellular tRNAs and rRNAs needed for translation. Zinc Finger Antiviral Protein and RNA-activated protein kinase inhibit translation initiation factors, and Shiftless suppresses translation recoding essential for the expression of retroviral enzymes. We outline common mechanisms that underlie the antiviral activity of multifunctional ISGs and discuss potential antiretroviral therapeutic approaches based on the mode of action of these ISGs.

Published: June 2024

Rotaviruses (RVs) are known to infect various avian and mammalian hosts, including swine. The most common RVs associated with infection in pigs are A, B, C and H (RVA-C; RVH). In this study we analysed rotavirus strains circulating on a porcine farm in the Western Cape province of South Africa over a two-year period. Whole genomes were determined by sequencing using Illumina MiSeq without prior genome amplification. Fifteen RVA genomes, one RVB genome and a partial RVC genome were identified. Phylogenetic analyses of the RVA data suggested circulation of one dominant strain (G5-P[6]/P[13]/P[23]-I5-R1-C1-M1-A8-N1-T7-E1-H1), typical of South African porcine strains, although not closely related to previously detected South African porcine strains. Reassortment with three VP4-encoding P genotypes was detected. The study also reports the first complete RVB genome (G14-P[5]-I13-R4-C4-M4-A10-T4-E4-H7) from Africa. The partial RVC (G6-P[5]-IX-R1-C1-MX-A9-N6-T6-EX-H7) strain also grouped with porcine strains. The study shows the continued circulation of an RVA strain, with a high reassortment rate of the VP4-encoding segment, on the porcine farm. Furthermore, incidents of RVB and RVC on this farm emphasize the complex epidemiology of rotavirus in pigs.

Published: June 2024

Vaccines are one of the most effective medical interventions, playing a pivotal role in treating infectious diseases. Although traditional vaccines comprise killed, inactivated, or live-attenuated pathogens that have resulted in protective immune responses, the negative consequences of their administration have been well appreciated. Modern vaccines have evolved to contain purified antigenic subunits, epitopes, or antigen-encoding mRNAs, rendering them relatively safe. However, reduced humoral and cellular responses pose major challenges to these subunit vaccines. Protein nanoparticle (PNP)-based vaccines have garnered substantial interest in recent years for their ability to present a repetitive array of antigens for improving immunogenicity and enhancing protective responses. Discovery and characterisation of naturally occurring PNPs from various living organisms such as bacteria, archaea, viruses, insects, and eukaryotes, as well as computationally designed structures and approaches to link antigens to the PNPs, have paved the way for unprecedented advances in the field of vaccine technology. In this review, we focus on some of the widely used naturally occurring and optimally designed PNPs for their suitability as promising vaccine platforms for displaying native-like antigens from human viral pathogens for protective immune responses. Such platforms hold great promise in combating emerging and re-emerging infectious viral diseases and enhancing vaccine efficacy and safety.

Published: June 2024

In this study, a circulating water experimental system was constructed to investigate the scale inhibition, scale removal, corrosion inhibition, and disinfection effects of industrial circulating water under the combined action of electromagnetic and electrochemical fields. The influence of these effects on water quality parameters and their scale inhibition and corrosion inhibition effects on hanging plate experiments were examined. Qualitative and quantitative analyses of scale samples were conducted using XRD (X-ray diffraction) and SEM (scanning electron microscopy), along with the evaluation of changes in water quality parameters (such as conductivity, hardness, Chemical Oxygen Demand (COD), turbidity, iron ions, and chloride ions) before and after the experiments. The results showed that after 360 h of circulation experiment, at a water temperature of 30 °C, electromagnetic field frequency of 1 kHz, electrochemical scale removal device voltage of 24 V, current of 10 A, and water flow rate of 0.6 m/s, the transformation of calcite to aragonite in CaCO3 scale samples occurred, with a 76.6% increase in aragonite content. Moreover, the conductivity decreased by 11.6%, hardness decreased by 42.0%, COD decreased by 59.7%, turbidity decreased by 48.1%, and chloride and iron ion concentrations decreased by 36.6% and 63.1%, respectively. The scale inhibition efficiency reached 53.8%, surpassing the effects of electromagnetic and electrochemical actions individually. These findings demonstrate that the combined action of electromagnetic and electrochemical fields can effectively enhance scale inhibition, scale removal, corrosion inhibition, and disinfection and algae removal effects.

Expanding anthropogenic activities, globally and in Egypt, have increased concentrations of heavy metals in surface and ground waters. Contamination of drinking water may threaten public health. In the present study, the concentrations of 10 heavy metals were analyzed from natural springs (6) and drilled wells (10) in the Nubian Sandstone Aquifer of the El-Farafra Oasis and the White Desert National Park, Egypt. The average concentrations of heavy metals were in most cases below critical values of the WHO drinking water standard, except for Fe and Mn (average values were 495 and 107 µg·L−1, respectively). There is a surface circulation that develops within limestone (Post-Nubian Aquifer System—PNAS) and feeds the springs, while the water present in the wells (at least for the deeper ones) comes from the ferruginous sandstone (Nubian Sandstone Aquifer System—NSAS). This double circulation could account for the differences in the EC and TDS values (typical of a circulation in limestone-type aquifers for springs) and the Fe and Mn enrichment coming from the ferruginous sandstone of the NSAS. The average chronic daily intake (CDI) values for heavy metals in the study area are listed in decreasing order in the following: Fe > Mn > Zn > Co > Ni > Cr > As > Pb > Co > Cd. The total hazard quotient (HQtotal = HQoral + HQdermal) and Hazard Index (HI) values calculated for different heavy metals were well below the acceptable limit, indicating no significant non-carcinogenic health risks to the residents of both areas via oral and dermal absorption of drinking water. Furthermore, the results obtained for the total risk to human health showed that oral ingestion is the major pathway. Carcinogenic risk analysis indicated that the Incremental Lifetime Cancer Risk (ILCR) values for Pb, Cd, Ni, and Cr were well below the acceptable limits.
Mechanism of Crude Oil Biodegradation in Bioreactors: A Model Approach
Authors: Costa Carlos , Millán Nicolás
Published: June 2024

Oil-degrading bacteria have the ability to degrade alkanes present in crude oil because of a special enzymatic system, the alkane hydroxylase complex (AlkH). The mechanism for the transport and degradation of alkanes present in crude oil remains unclear, especially related to the first step in hydrocarbons oxidation. In this work, we present a novel model of the crude oil biodegradation mechanism by considering the contact between the oil drop and the cell and calculating the mass transfer coefficients in three oleophilic bacteria (B. licheniformis, P. putida and P. glucanolyticus). The mass transfer coefficients are evaluated under critical time conditions, when the kinetics and mass transport are in balance, and the difference in the values obtained (kL α = 1.60 × 10−3, 5.25 × 10−4 and 6.19 × 10−4 m/d, respectively) shows the higher value of the mass transfer coefficient and higher biodegradation potential for B. licheniformis. Because the morphology of the cells has been analyzed by optical and electron microscopy, in the proposed model, the increase in the size of the cells in P. glucanolyticus compared to P. putida exhibits higher values of the mass transfer coefficients and this is attributed, as a novel statement, to a bigger window for alkanes transport (contact area) when the external area of the cell is bigger.

Published: June 2024

The Dublin Declaration was initiated by some members of the Organizing Committee of the "International Summit on the Societal Role of Meat" which was held on 19 and October 20, 2022 in Dublin. The Dublin Declaration insists more broadly on the societal role of livestock, highlighting the advantages and benefits of livestock farming sys-tems, while proposing solutions for the necessary improvements. The Declaration can only be signed by scientists who carry out research, teaching, publication or representation activities, and who are in some way affiliated with a university or a research-oriented organization. This Declaration aims to give a voice to the many scientists around the world, who carry out their research with diligence, honesty and success in different disciplines in order to propose a balanced vision on the future of animal productions. A discussion is then carried out on the state of scientific "controversy" around farming, with a greater development concerning the consumption of meat in de-bates between scientific communities.
Les éleveurs face aux risques épizootiques répétés. le cas exemplaire des éleveurs de brebis laitières du pays basque confrontés a l’agalactie contagieuse
Authors: Nicourt Christian , Cabaret Jacques
Published: June 2024

Le Pays basque est particulièrement frappé par différentes épizooties qui affectent les élevages ovins. La configuration de ces élevages, c’est à dire leur petite taille, leur grande densité dans la région, leurs différentes manières d’élever les animaux se distinguent des normes habituelles d’élevage des brebis en France et semble contribuer à cette expression des maladies. L’alimentation des animaux ne provient pas majoritairement des exploitations, mais de pâtures collectives aux coûts de location modiques, gérées par des collectivités territoriales. Dans ce contexte, les épizooties mettent les éleveurs à l’épreuve, en leur imposant des contraintes drastiques, qui ne leur permettent plus d’utiliser ces pâtures. Qu’en est-il alors de leurs manières de travailler et d’être ensemble sous cette contrainte ? En prenant le cas d’une de ces épizooties particulièrement présente au Pays basque -l’agalactie contagieuse -après avoir examiné les manières singulières de travailler de ces éleveurs, nous analyserons comment ils sont vulnérabilisés par la survenue de l’agalactie contagieuse et enfin comment sa gestion publique est source de tensions.
Enjeux biotechnologiques (nouvelles techniques génomiques) : vers une évolution de la réglementation européenne ?
Authors: Regnault-Roger Catherine
Published: June 2024

The regulations applied to NGTs (New Genomic Techniques, particularly genome editing, e.g. CRISPR) constitute a key point that underlines the place each country wants to give them for developing innovative solutions in human health, animal health and welfare, as well as in plant health and also to confront climate change. Faced with these immense prospects as well as better assessed risks with genome editing, many countries (USA, Japan, Argentina, Brazil, Australia etc.) have decided to deregulate the majority of genome editing products. On contrary, the European Union (EU) after the judgment of the Court of Justice (CJEU) of 2018, indicated that GMO regulations must be applied, found itself isolated. This context has given rise to political and academic debates. Consequently, the European Commission decided to launch a strategic initiative for changing the regulations applied to some editing products for plants only. Some key elements of these issues are proposed here for a better understanding.
Duel franco-prussien. Quand la revue scientifique d’Émile Alglave arbitrait les différents de Louis Pasteur et de Rudolf Virchow
Authors: Rosolen Serge Georges , Dupouy-Camet Jean
Published: June 2024

Le bicentenaire de la naissance de deux savants exceptionnels du XIX e siècle, le français Louis Pasteur et l’allemand Rudolf Virchow a été fêté à un an d’intervalle. Le premier, chimiste et microbiologiste, a été qualifié de bienfaiteur de l’humanité, le second, médecin et père de l’anatomie pathologique, représentant d’un libéralisme à tendance sociale, a exercé une influence considérable sur la science allemande. S’ils ne se sont rencontrés physiquement qu’une fois ou deux, ils ont pu lire leurs articles parus dans la Revue Scientifique de la France et de l’ Étranger dirigée par É mile Alglave. Le conflit franco-prussien de 1870-1871 va exacerber leur patriotisme. Ils mettront en sourdine leurs aspirations de chercheurs pour s’ériger en thuriféraires de la civilisation et en défenseurs du génie de leur peuple, au nom de la Science. Nous analysons deux textes publiés dans La Revue Scientifique de la France et de l’ Étranger en 1871 qui illustrent les prises de position des deux savants.
Les chats ratiers du neveu de Pasteur, Adrien Loir. Une expérience oubliée dans la lutte contre les rats
Authors: Rosolen Serge Georges
Published: June 2024

Fighting against the proliferation of rats is still a public health concern. Between the two world wars, Adrien Loir, Pasteurs nephew by alliance, had successfully used rat cats to eliminate rats in the city and the harbour of Le Havre. This method of offensive fight against rats had been the subject of numerous articles o the press of the 1930s but it was then mysteriously forgotten, as was the merits of Adrien Loir who was an active collaborator of his uncle and who participated in the Pasteurian epic. In this year of Louis Pasteurs birth bicentanery, it is appro-priate to pay tribute to him and his cats.
Les vaccins aujourd’hui chez l’animal : 1. bases technologiques, pratiques et sociologiques
Authors: Ridremont Bertrand
Published: June 2024

Les vaccins vétérinaires représentent en France un quart du marché du médicament vétérinaire. Le taux de pénétration de la vaccination en médecine vétérinaire en France dépend des espèces : très élevé chez les volailles et porcins, élevé chez les chevaux et les chiens, encore modéré ou irrégulier chez les bovins, faible chez le chat et les petits ruminants. Les cibles des vaccins vétérinaires sont essentiellement les virus et bactéries, mais aussi les parasites et les champignons. Les voies d’administration sont très variées, particulièrement chez les volailles. Parmi les technologies vaccinales utilisées en médecine vétérinaire, on peut distinguer les vaccins conventionnels (vivants atténués, inactivés, à base de toxines ou «toxoids ») et les vaccins de nouvelle génération (recombinants, vecteurs, à ADN et à ARN), ainsi que les autovaccins. Un objectif de la vaccination des animaux est de limiter les administrations, sources de stress, à travers des vaccins multivalents à administration unique et longue durée d’immunité. Motivations et freins de la démarche vaccinale varient selon les espèces, notamment entre animaux de rente et de compagnie.
Connaissances de la rage, perception du risque et observance réglementaire : propositions issues de deux enquêtes a l’école nationale vétérinaire d’Alfort (ENVA)

Although France is considered rabies-free according to WHO, the RABV and EBLV-1 viruses have recently caused human and animal victims in France. Through two surveys at the EnvA, we sought to assess the knowledge of do-mestic carnivore owners, clinicians and students about rabies and travel regulations, their perception of rabies risk and their degree of compliance with the regulations. The knowledge of owners appears to be extremely de-ficient, while that of clinicians and students present limitations. Risky behaviors are highlighted as well as a non-optimal consideration of rabies risk by professionals. Faced with this worrying finding, avenues for improvement are proposed, centered on better communication targeting all actors, both qualitatively and quantitatively, and on possible regulatory changes based on risk analysis.
Ceux qui pieusement sont morts pour la patrie , ou le souvenir de la croisade albigeoise chez les Félibres au siècle dernier

Our ancestors, the Cathars

The Cathars, unvoluntary heroes of the Crusade that put an end to any possible occurence of Occitanian indépendance, could have become excellent national heroes to the builders of the "Occitanian Renaissance'' movement which took place during the 19 th century. It was, in fact, because the liberal French historians took such interest in them that they attracted the attention of the founders of "Occitanist ideology" such as Mary Lafon, or Mistral at the outset of his career. And, during the decades that followed 1870 - when Mistral started to evolve - the Albigensian theme was to be found throughout the works of a great many authors with the two following ways of seeing things :

-a) the Crusade brought about the end of the South.

-b) the Cathars are the symbol of the freedom of thought that prevailed in the South.

That much said, contradictions soon arose, first of all for geographical reasons although the Provençal writer Gras was with the Albigencists, the latter were fundamentally recruited on the western side of the Rhone river, the Provençal people often preferring historical memories that belonged mored specifically to their own region.

Problems of a political or religious nature also came to light : Albigencism was a delight to the "red-wing". Felibres such as Fourès or L.X. de Ricard, whereas the Catholics, on this matter, took up the position of their Northern co-religionists. The controversy, which was published in Mistral's paper "L'Aïoli", in the year 1897, between Marius André who was a Catholic, and Dévoluy, a nationalist, perfectly summed up the difficulty that lay in trying to turn the Albigenses into some basic Myth capable of rallying quite every constituent of the "Felibrian Renaissance".
Les Vaudois et l'au-delà au XlVème siècle en Europe centre-orientale

Recent scholarship, particularly the fundamental source editions of A. Patschovsky and D. Kurze make apparent the dynamic development of Waldensian community in XIV th century Bohemia, Silesia, Pomerania and Brandenburg. The believers were recruited mainly from the immigrants of German origin. The records of inquisitorial interrogations permit to recreate a set of beliefs and eschatological images of the local Waldensian communities. Not a few Waldensians participated in the Catholic cult and the Catholic popular devotions. It did not remain without influence on their views of the Other World.

Despite being deeply rooted in Waldensian beliefs, a dual view of the Other World yielded to a pressure exerted by the Catholic idea of purgatory. Among the followers of heterodoxy there appeared, against their own doctrine, timid hopes for the existence of a place, where a posthumous punishment might be passed. These attitudes were kept alive by the concern expressed for the fates of the souls of relatives and friends.

The Waldensian structure of the Other World showed affiliation between particular abodes of human souls. The Paradise was also connected with Earth through the voyages of priest missionaries returning periodically for God's gifts and graces / the renewal of charisma / . It was wide open for the followers of a choser community, but also accessible for the good and the just who belonged to the "aliens" / Catholics /. The images of everlasting punishment refered to the condemned Catholic clergy and all other persecutors of Waldensians. However, among the dwellers of Waldensian hell, one can also find the stereotypes of the damned, known from the didactic teachings of the Church.

The dominating motif of Waldensian beliefs - the immediate determination of soul's fate after death - succumbed to the images invoking supplementary eschatological spaces, functioning as "quasi-refrigerium". Possibly, a "fair meadow" present in the images of Silesian Waldensians filled such a part. Mid-European Waldensian movement was becoming a syncretic belief, crumbling under the impact of both the Catholic catechetical instruction and the "popular Christianity".
