Authors: Mansur Sumarni , Baharuddin Nurul Akidah , Wan Yusoff Wan Nor Anasuhah , Abd Aziz Azreen Junaida , Somalu Mahendra Rao
Published: July 2023

A new strategy to reduce the operating temperature of the solid oxide fuel cell (SOFC) is needed to foster the progress of developing high-performance and stable SOFC as a solution to the thermal stress and degradation of the cell components induced by high-temperature SOFC. The use of lithium (Li) as a cathode can increase the cell’s efficiency, as it allows for faster ion transport and a higher reaction rate. This study presents an attractive approach to using a Li-based cathode by combining Li with cobalt (Co) to form LiCo0.6Sr0.4O2 (LCSO). In this work, a precursor consisting of Li, Co, and strontium (Sr) was prepared via the glycine-nitrate combustion method. The precursor was calcined at two different calcination temperatures (800 and 900 °C) prior to ink formulation and symmetrical cell fabrication in order to study the effect of calcination temperature on the structural and electrochemical behaviour of a Li-based cathode. The precursor LCSO powder was characterised using X-ray crystallography (XRD) to determine the crystal structure and composition of the developed LCSO. The electrochemical performance of the fabricated symmetrical cell was tested using electrochemical impedance spectroscopy (EIS) to obtain the cell’s resistance information, which is related to the cell’s ionic and electronic conductivity. SDC electrolyte with LCSO calcined at 800 °C has a higher crystallinity percentage and a more porous structure compared to LCSO calcined at 900 °C. The porous structure enhanced the electrochemical performance of the cell, where the symmetrical cell has the highest conductivity (0.038 Scm−1) with the lowest activation energy (0.43 eV). The symmetrical cell was also able to achieve 2.89 Ω cm2 of area-specific resistance (ASR) at 800 °C of operating temperature. In conclusion, the SDC electrolyte with LCSO calcined at 800 °C is the promising cathode material for SOFC applications. The result of this study can benefit the SOFC field of research, especially in the development of intermediate temperature-SOFC.
The School Community’s Role in Educating for Responsibility for Inclusion
Authors: Zammit Alina M. , Zammit Raymond
Published: July 2023

This study explores responsibility for inclusion, a notion rooted in the belief and practices of various religions. It draws on the thoughts of Emmanuel Levinas, Hannah Arendt and Paolo Freire, all of whom were greatly influenced by their religious tradition. Ten qualitative interviews were performed with senior school leaders. Data were interpreted through thematic analysis, and the results show that inclusion starts from the self who welcomes the other. Inclusion of students with severe disabilities, especially with severe autism, remains problematic at schools in Malta, and headteachers seem to struggle to implement inclusive values and attitudes. Successful methods for better inclusion include collaboration of all school community members, the involvement of students in decision making, participation of all students in school events without any discrimination, the Peer Preparation Programme and the buddy system.

Published: July 2023

Near-miss events are usually identified as adverse events that could have turned into incidents/injuries but, due to an intervention of a safety system or by chance, developed into harmless situations instead. Past and present studies have also outlined the importance of collecting and analyzing near-miss events, as they have same causes of more serious events, thereby allowing for more effective preventative measures at the workplace. Although their importance has been outlined for several years, standard models for designing near-miss management systems (NMMSs) are still lacking and cannot yet support companies in their full-scale application. Despite this condition, NMMSs are applied in several industrial sectors, such as in the construction, mining, chemical, and nuclear industries. The aim of this study is to analyze how companies are developing their own NMMSs. An exploratory analysis was developed through survey analysis; it was provided to a sample of Italian companies in order to evaluate the adoption level of NMMSs as well as current practices applied by companies. The sample included companies of different sizes in the industrial sector. The results extracted from the field analysis outline interesting issues that point out current procedures adopted for the identification, collection, and analysis of near-miss events as well as real benefits and criticalities related to the application of NMMSs.

Published: July 2023

Organic wastes and by-products from several activities, including food industries, farming, and animal husbandry, are a hygiene threat when aerobically decomposed. Therefore, their management is crucial for public health. In this direction, anaerobic digestion (AD) systems may be the solution by transforming waste into energy, which may decrease the environmental impact. However, their efficacy should be carefully examined. In this innovative study, we evaluated the physicochemical and microbial characteristics of liquid digestate (LD) retrieved from organic animal wastes in northern Greece using nanofiltration. Using treatment technologies, including physical (solid–liquid separation, microfiltration, and nanofiltration) and biological (anaerobic digestion), heavy metals and microbial (i.e., Salmonella spp., Escherichia coli, and Enterococcus faecalis) concentrations were reduced and nutrients were recovered. This work sets the basis for the efficient management of liquid digestate. Our method may enable the use of treated liquid digestate for unlimited irrigation water and other industrial applications of water. Apart from the sanitation process, the recovery of nutrients for soil fertilization seems to be a more sustainable way for future agricultural practices.
Unveiling Supply Chain Nervousness: A Strategic Framework for Disruption Management under Fuzzy Environment
Authors: Mistarihi Mahmoud Z. , Magableh Ghazi M.
Published: July 2023

Supply chains are increasingly vulnerable to disruptions due to the complex and interconnected nature of global business operations. Supply chain nervousness (SCN) leads to inefficiencies and disruptions in the flow of goods and services. Managing SCN is critical for sustaining the continuity of business operations in today’s dynamic and uncertain business environment. To address this issue, this study proposes a strategic framework that integrates key components of supply chain nervousness management and establishes a robust framework that prioritizes these factors based on their relative importance. By incorporating the fuzzy-ELECTRE methodology into the analysis, the proposed framework acknowledges the inherent uncertainties and imprecisions present in supply chain disruptions. It offers a systematic and comprehensive approach to prioritizing and managing SCN factors, considering both qualitative and quantitative assessments. To validate the effectiveness of the proposed framework, a case study is conducted in a real-world supply chain context. The results highlight demand variability as the factor with the greatest impact on SCN. Moreover, the results demonstrate the framework’s ability to effectively manage SCN by providing valuable insights for practitioners and researchers seeking to understand the causes of supply chain nervousness and mitigate its impact. The contributions of this research lie in providing decision-makers with a strategic framework for disruption management under fuzzy environments. The proposed approach enhances the understanding of SCN and enables proactive decision making to mitigate its negative consequences.

Authors: Li Qian , Xiao Zezhong , Zhao Yanyun
Published: July 2023

The existing means for classifying new energy industry policies are mainly based on the theory of policy instruments and manual encoding, which are highly subjective, less reproducible, and inefficient, especially when dealing with large-scale policy texts. Based on the theory of policy instrument, the research tried to apply the automatic classification model based on BERT to new energy industry policies to improve its classification efficiency and accuracy. A new energy industry policy classification model was established to train on policy texts and to compare the policy classification effects with the other two commonly used text classification models. The model comparison results show that the BERT model achieves higher precision, recall, and F1 score, indicating a better classification effect. Furthermore, adding topic sentences to training texts can effectively improve the classification effect of the BERT model. The policy classification results show that environmental policies are the most prevalent in new energy industry policies, while demand-side policy instruments are underutilized. Among the 11 types of subdivided policies, the application of goal planning policies is overflowing.
Bridge Performance Recovery Test after Strengthening with a Prestressed CFRP Laminate
Authors: Li Yang , Li Fangyuan
Published: July 2023

This paper introduces the strengthening of a concrete bridge using a CFRP laminate anchorage system and describes the static and dynamic test process, including the loading method and the test results. This paper compares the stress, strain, and deformation of each key section before and after reinforcement under static loads, moving loads, braking vehicles, and jumping vehicles to demonstrate the strengthening effect of the bridge and the performance of the CFRP laminate. The CFRP laminate anchorage system effectively restores the structural elastic properties of the bridge, enabling the prestressed CFRP laminates and the bridge structure to synergistically function as a composite, exhibiting exceptional operational performance. After reinforcement, the maximum dynamic deflection in the middle span after reinforcement decreases by 25.73%, and the maximum dynamic strain in the middle span decreases by 18.00%; under the jumping vehicle, the damping ratio decreases by 43.69%. By strengthening with prestressed CFRP, the original damaged bridge can have its performance restored and its service life extended, and the need for bridge demolition and reconstruction is avoided. This brings about social benefits by saving raw materials, reducing demolition waste, and protecting the environment.

The objective of this study is to identify the relationship between service quality, customer satisfaction, and customer loyalty in mobile social media. Moreover, this study examines the role of customer satisfaction as a mediator. The proposed research model consists of four dimensions of mobile service quality (usefulness, convenience, design, and security/privacy) as well as customer satisfaction and customer loyalty. The survey used the self-administrated method. A total of 256 responses were used in the data analysis. We estimated the hypothesized relationships of the research model using a structural equation modeling technique. The results are as follows: first, usefulness, convenience, design, and security/privacy significantly and positively affect customer satisfaction. Second, customer satisfaction has a significant and positive impact on customer loyalty. Third, customer satisfaction mediates the relationship between service quality and customer loyalty; in particular, convenience, design, and security/privacy are completely mediated while usefulness is partially mediated. These results can serve as a valuable reference for mobile social media providers to manage services and improve service quality and customer satisfaction.

Authors: Su Weizhou , Wei Nieping , Yuan Zihan , Guo Sidai
Published: July 2023

Environmental information disclosure has become a widely-used tool to encourage the participation of multiple market players in environmental governance. However, it remains unclear whether it can promote the efficiency of capital allocation in enterprises. This study uses econometric modeling and data from heavily polluting enterprises in Chinese A-shares between 2013 and 2020 to explore the impact of environmental information disclosure on capital allocation efficiency, as well as its mechanisms. It is found that environmental information disclosure significantly and robustly enhances the efficiency of capital allocation, and the effect varies by firm’s size, ownership, life cycle, and region. Nevertheless, employees and creditors are found to have a negative moderating role in this effect. These findings have important implications for the simultaneous improvement of environmental performance and capital allocation efficiency in the context of China’s ecological civilization system and high-quality economic development and for promoting a “win-win” situation for environmental protection and economic growth.
Profitability Analysis of Selected Low Impact Development Methods for Decentralised Rainwater Management: A Case Study from Lublin Region, Poland
Authors: Iwanek Małgorzata , Suchorab Paweł
Published: July 2023

Water scarcity affects at least 11% of the population and 17% of the territory of the European Union. Simultaneously in cities there is a problem of urban floods caused by violent and intense rainfalls. Decentralized drainage systems are designed to capture rainwater runoff at the place of precipitation and improve the hydrological conditions through the use of surface and subsurface infiltration, retention, and evapotranspiration techniques. The purpose of this paper was to evaluate the financial profitability of selected Low Impact Development (LID) methods for decentralized management of rainwater disposed from the roofs of two different buildings. In the presented conditions, the use of dual installations and infiltration tunnels turned out to be cost-effective solutions, whereas infiltration boxes were unprofitable for both buildings. The most unprofitable solution would become profitable if the investment costs were reduced by as much as 67% or if it was possible to generate 2.28 times more benefits. Although the research was carried out for specific conditions, the obtained results may be helpful in the implementation of similar investments. They are also a kind of contribution to the assessment of the cost-effectiveness of LID on a global scale due to the universality of the proposed research methodology.

Authors: Yue Wenjun , Chen Si , Gao Lihua , Li Ningyu , Liu Linsong
Published: July 2023

The proficient supply of water and nitrogen is a key factor in facility agriculture. In order to pursue high yields, most farmers blindly irrigate and fertilize, leading to yield reduction, quality decline, soil salinization, and fertility destruction. A successive two-year greenhouse experiment was carried out on fruit quality, yield, irrigation water use efficiency (IWUE), and nitrogen use efficiency (NUE) of greenhouse muskmelon (Cucumis melo L.) under drip fertigation, which can provide a scientific basis for local muskmelon intensive production in Southeast China. The experiments were conducted in 2020 and 2021, with three irrigation levels 80% (W1), 100% (W2), and 120% (W3) of ETc and three N levels 60 (N1), 95 (N2), and 130 (N3) kg N ha−1. The amount of drip irrigation water was determined every 5 days based on crop evapotranspiration (ETc). The seasonal irrigation amount ranged from 209.77 mm to 298.86 mm in 2020 and from 201.22 mm to 286.04 mm in 2021. The highest muskmelon yield was obtained in the treatment of W3N3 with an average of 27.38 t ha−1 in 2020 and 27.10 t ha−1 in 2021. Although the yield was improved by increasing nitrogen supply, there was no significant difference between N2 and N3 treatment in two years under the irrigation level of W2 and W3. The highest irrigation water use efficiency was observed in the W1N3 treatment in 2020 and 2021. The NUE increased with decreasing N rates at the same irrigation level. Under the same nitrogen application level, TSS and Vc under low water (W1) were higher than that under medium water (W2) and high water (W3) treatment. The highest content of nitrate in low water and high nitrogen (W1N3) treatment was 55.41 µg/g in 2020 and 52.50 µg/g in 2021, respectively. The yield and quality of muskmelon are often incompatible, for instance, W2N2 treatment can obtain a higher yield, but W1N2 treatment maximizes Vc, TSS of muskmelon quality. Our findings suggest that the irrigation level of 1.0 ETc, nitrogen level of 95 N ha−1, and 3500 kg·ha−1 of decomposed organic fertilizer was recommended as the best combination, which can improve the yield, quality, IWUE, NUE of muskmelon under drip fertigation with soil mulching in the experimental site.
Statistical Roughness Properties of the Bed Surface in Braided Rivers
Authors: Ren Baoliang , Pan Yunwen , Lin Xingyu , Yang Kejun
Published: July 2023

Braided rivers are widespread in nature, and their bed morphology is complex and variable. This paper aims to investigate and quantitatively analyze the bed surface roughness of braided rivers utilizing statistical theory. In this paper, a physical model of braided rivers is developed, and four constant discharge experiments are carried out. Based on Structure-from-Motion photogrammetry and direct measurement of bedload transport using a load cell, data on bedload transport rate, bed morphology, and bed elevation are obtained, facilitating the in-depth investigation of the correlations between these parameters. The results show that the morphological active width increases with increasing discharge. There was a significant positive correlation between the morphological active width and the bedload transport rate, although there is considerable scatter due to the inherent variability in braided river morphodynamics. The elevation probability distribution of bed surfaces shows negative skewness and leptokurtic distribution. There is a relatively significant correlation between skewness and the dimensionless bedload transport rate. The two-dimensional variogram values of bed elevation are variable, and the bed is anisotropic. Additionally, both the longitudinal sill and correlation length values exhibit an increase with the rise in stream power. Remarkably, the correlation between the dimensionless sill and correlation length, as well as the dimensionless bedload transport rate, proves to be highly significant. Consequently, this correlation can serve as a reliable general factor for predicting bedload transport rate in the reach.

Efficient Algorithm for Dominatig Set In Graph Theory Based on Fundamental Cut-Set
Authors: Öztemiz Furkan , Karci Ali
Published: July 2023

Determining the minimum dominating set in connected graphs is one of the most difficult problems defined as NP-hard. In this problem, it is aimed to determine the important nodes that can influence all nodes via the minimum number of nodes on the graph. In this study, an efficient near-optimal algorithm showing a deterministic approach has been developed different from the approximation algorithms mentioned in the literature for discovering dominating set. The algorithm has O(n3) time complexity in determining the Dominating Set (DS). At the same time, the algorithm is an original algorithm whose solution is not random by using a fundamental cut-set. The DS algorithm consists of 3 basic phases. In the first phase of the algorithm, the algorithm that constructs the special spanning tree (Karci Max tree) of the graph is developed. In the second phase, the algorithm that finds the fundamental cut sets using the Kmax spanning tree is developed. In the last phase, Karci centrality node values are calculated with fundamental cut set and by using these Karci centrality node values, an algorithm has been developed to identify DS nodes. As a result of these three phases, the dominance values of the nodes on the graph and the DS nodes are calculated. The detected Karci centrality node values give priority to the node selection for determining the DS. All phases of the developed DS and Efficient node algorithms were coded in R programming language and the results were examined by running on sample graphs.

Published: July 2023

The interest in the problem of hereditary forms of breast cancer is due not only to the increase in the number of patients, but also to the existing features in relation to the phenotypic characteristics of these tumors, course features, and sensitivity to various therapy options. Unfortunately, the data of clinical trials that exist to date do not provide a complete picture of the course of various forms of hereditary breast cancer, sensitivity to therapeutic agents, adequate examination volumes and preventive measures. In this regard, there is a need to conduct prospective randomized trials to optimize treatment, screening and prevention programs. The rapid development of technologies in the field of molecular biology has made it possible to identify about 20 genes, the presence of mutations in which causes an increased risk of developing breast cancer. The aim of this review was to summarize the available data on the role of structural rearrangements of genes of varying degrees of penetrance associated with hereditary predisposition to breast cancer. The mechanism of hereditary breast cancer forms development is associated with rearrangements in DNA repair genes of varying degrees of penetrance. The identification of these mutations is of strategic importance for early diagnosis and the transition from an empirical to a targeted personalized approach in the treatment of various types of cancer. Understanding the pathogenesis of the disease at the molecular level makes it possible to make a breakthrough in the field of pharmacological innovations in order to create new selective classes of drugs in effective targeted therapy.
The Chemical Composition of Helvine-Group Minerals and Implications for Ore Genesis: Case Studies from the Dawan, Qidushan, and Taoxikeng Deposits
Authors: Zhu Yiting , Li Xiaofeng , Wei Xinglin
Published: July 2023

Helvine-group minerals have characteristic chemical compositions and textures and occur in different environments within magmatic–hydrothermal deposits. However, their origin is still unclear. There are several quartz-vein beryllium deposits with different element assemblages existing in southeastern China; these include the Dawan Be-Mo, Qidushan Be-Zn-Sn, and Taoxikeng Be-W deposits. We present the chemical composition of helvine-group minerals analyzed by electron probe microanalysis and laser ablation inductively coupled plasma mass spectrometry, in addition to zircon sensitive high-mass-resolution ion microprobe U-Pb and cassiterite laser ablation inductively coupled plasma mass spectrometry U-Pb ages. The zircon and cassiterite U-Pb data indicate that the Qidushan deposit formed during the Late Cretaceous (127–132 Ma). The electron probe microanalysis data show that the helvine-group minerals from the three deposits are helvine and/or danalite. A wide variety of different trace elements display high concentrations in the different deposits [e.g., helvine-group minerals from the Dawan deposit are rich in Li, B, Sc, V, Ga, Y, Sn, Cs, Th, and U; those from the Qidushan deposit are rich in Sc, Cd, and Sn; whereas those from the Taoxikeng deposit are rich in Y, Cd, Sn, Ta, and total rare-earth elements (ΣREE). The material analyzed from the Dawan deposit has the highest concentrations of Li (28.03–134.96 ppm), Sn (126.01–709.24 ppm), Sc (108.10–287.64 ppm), Cs (0–37.24 ppm), Th (4.78–112.63 ppm), and U (0.79–4.13 ppm). The material analyzed from the Taoxikeng deposit has the highest concentrations of Y (594.95–899.95 ppm), Cd (22.63–25.21 ppm), Ta (0.41–0.86 ppm), and ΣREE (281.69–451.79 ppm). However, those from the Qidushan deposit have the lowest concentrations of Y (10.21–37.70 ppm), Sn (0–26.88 ppm), U (0–19.06 ppm), Eu (0–0.14 ppm), and Cs (being below the detection limit). All of them are rich in heavy REEs but poor in light REEs, with distinctive REE patterns. Our results reveal that both crystallographic substitution and fluid composition control the enrichment of trace elements in helvine-group minerals. The textures and trace element compositions of helvine-group minerals can represent various parageneses and ore-forming fluid compositions. We propose that the δEu values and (La/Yb)N ratios can be used as markers to discriminate the genesis of helvine-group mineral precipitated from different environments based on the chemical compositions and the origin of ore-forming fluids.

Published: July 2023

In 2021, Banco de Portugal started a new cycle of strategic planning. The Banco de Portugal’s fourth strategic plan (i.e., PE21-25) was published at the institutional website, and defines 35 priorities/objectives grouped into five strategic guidelines. The interrelationships and causal dynamics of those guidelines and priorities are the core of the current research. The main purpose is to develop a set of actions aiming at producing recommendations for prioritizing the 35 strategic objectives using the Decision MAking Trial and Evaluation Laboratory (DEMATEL) method. The objective is to develop a constructivist procedure that, with the direct collaboration of a panel of relevant decision makers, grants the analysis objectivity and empirical substance for making recommendations at the strategic level. Contributing to the literature on central banking strategic planning is an additional objective. The results of the DEMATEL application include the identification of three priorities as central factors (i.e., high prominence and high relationship), and a hierarchical list of the PE21-25 strategic priorities analyzed, including their cause-and-effect relationships.
Les cinq sens au Moyen Âge : État de la question et perspectives de recherche
Authors: Palazzo Éric
Published: July 2023

Le présent article propose en premier lieu une synthèse complète de la bibliographie et de l’historiographie des recherches sur les cinq sens au Moyen Âge. Dans cette synthèse, les principaux travaux des médiévistes sur les cinq sens sont passés en revue ainsi que ceux émanant de philosophes, d’anthropologues et de sociologues. La première partie de l’article vise également à dégager les grands thèmes de la recherche sur les cinq sens dans les sciences humaines tout au long du xxe siècle et de poser les bases d’une réflexion nouvelle sur la place des cinq sens dans la définition de la liturgie chrétienne médiévale et du rôle de l’activation de l’art dans la pratique des rituels. La seconde partie de l’article ouvre des pistes de recherche nouvelles pour saisir la façon dont les cinq sens constituent des éléments majeurs de la définition de la liturgie médiévale. Pour ce faire, l’attention est portée sur le concept de synesthésie dont l’origine remonte à saint Augustin, du moins en perspective chrétienne, et qui joue un rôle majeur dans la théologie de la liturgie. À la suite de quoi, une approche nouvelle de l’art dans la liturgie est rendue possible à partir de l’idée de l’activation sensorielle des images du lieu de culte et des objets liturgiques destinée à rendre réellement présente la synesthésie dans le rituel. Au final, ces recherches nouvelles sur les cinq sens dans la liturgie et dans l’art médiéval permettent de mieux cerner des notions fondamentales de la théologie chrétienne, telles que l’harmonie et l’ordre.

It also addresses the potential for imagery to be evoked to support re-membering conversations. Through the use of narrative practices, an image can become a site where new, preferred meaning can be made.
Narrative therapy in trauma care
Authors: Bayes Joanna
Published: July 2023

The telling of stories is how we make sense of our lives. With trauma, our understandings of our stories are dramatically altered and somewhat reduced. This is particularly so when a patient has a near-death experience, multiple serious injuries and must be passive in order to survive. There is a need to rebuild a narrative in which the person is active, congruent and competent. My story starts with falling off a balcony on the first night of a holiday. Initially I adapted poorly to the loss of agency that is essential to recovery. I clashed with the intensive-care nurses as I fought to protect myself from pain within a state of sedation, delirium and confusion. Trauma deeply disturbs and destabilises a person’s sense of themselves. It can permanently impair many facets of our lives and damage our relationships to family and community. The collaborative and interactional process of narrative therapy can rebuild agency and empower trauma survivors. It can help prevent the patient from extending trauma-related vulnerability, damage and passivity into the future. It can assist with processing trauma and gently fostering new stories to incorporate the uniqueness, depth and complexity of trauma and human lives.

One of the methods to improve the quality of practical training of specialists is the using of simulation technologies. Simulation training in medicine is the latest technology for obtaining knowledge and assessing the degree of mastering practical skills and competencies, which is based on modeling close to reality, simulating a clinical “case” using training models of varying complexity and realism [3, 4]. The article describes the introduction of the training module “Respiratory therapy in severe pneumonia” in the training of residents, anesthesiologists-resuscitators in the specialty “Anesthesiology and Resuscitation” using the “TestChest” dynamic human lung model simulator system in the Bashkir State Medical University of the Ministry of Health of Russia.
STABLE CARBON AND OXYGEN ISOTOPES OF SOME CARBONATE-FLUORAPATITES FROM CENOMANIAN AND TURONIAN SEQUENCES, BOHEMIAN CRETACEOUS BASIN, CZECH REPUBLIC
Authors: Al-Bassam Khaldoun S.
Published: July 2023

Stable carbon and oxygen isotopes were analysed in the structural CO3 of carbonate-fluorapatite in phosphate nodules and coprolites present in distinctive horizons at the Cenomanian – Turonian boundary and in late Turonian sequence at the Bohemian Cretaceous Basin of the Czech Republic. The results indicate that the structural CO3 in the analysed carbonate-fluorapatites is depleted in δ13C relative to CO3 in carbonates of comparable age and all samples show negative δ18O values close to those recorded in mid-Cretaceous carbonate-CO3. The obtained δ13C values, however, are higher than those reported in apatite-CO3 of the late Cretaceous Tythyan upwelling-type phosphates. The δ13C results are interpreted to indicate that phosphogenesis have taken place in an environment rich in the light isotope of carbon, similar to that usually prevails in the organic-rich pore water below sedimentwater interface. The higher δ13C values in the studied apatites relative to their Tethyan analogues may reflect the signature of the well-documented δ13C excursion of the Oceanic Anoxic Event 2 at the Cenomanian-Turonian boundary. The δ18O values suggest paleotemperatures expressive of the mid-Cretaceous climatic warming and a lower paleosalinity than that of normal well-circulated seawater.

Matrix metalloproteinases in rheumatoid arthritis and osteoarthritis: a state of the art review
Authors: Pulik Łukasz , Łęgosz Paweł , Motyl Gabriela
Published: July 2023

Although the pathological mechanisms involved in osteoarthritis (OA) and rheumatoid arthritis (RA) are different, the onset and progression of both diseases are associated with several analogous clinical manifestations, inflammation, and immune mechanisms. In both diseases, cartilage destruction is mediated by matrix metalloproteinases (MMPs) synthesized by chondrocytes and synovium fibroblasts. This review aims to summarize recent articles regarding the role of MMPs in OA and RA, as well as the possible methods of targeting MMPs to alleviate the degradation processes taking part in OA and RA. The novel experimental MMP-targeted treatments in OA and RA are MMP inhibitors eg. 3-B2, taraxasterol, and naringin. While other treatments aim to silence miRNAs, lncRNAs, or transcription factors. Additionally, other recent MMP-related developments include gene polymorphism of MMPs, which has been linked to OA susceptibility, and the MMP-generated neoepitope of CRP, which could serve as a biomarker of OA progression.

Time-scale dependence of airborne fraction and underlying climate-carbon cycle feedbacks for weak perturbations in CMIP5 models
Authors: Torres Mendonça Guilherme L. , Reick Christian H. , Pongratz Julia
Published: July 2023

Abstract. The response of the global climate-carbon cycle system to anthropogenic perturbations happens differently at different time scales. The unraveling of the memory structure underlying this time-scale dependence is a major challenge in climate research. Recently the widely applied α-β-γ framework proposed by Friedlingstein et al. (2003) to quantify climate-carbon cycle feedbacks has been generalized to account also for such internal memory. By means of this generalized framework, we investigate the time-scale dependence of the airborne fraction for a set of Earth System Models that participated in CMIP5 (Coupled Model Intercomparison Project Phase 5); the analysis is based on published simulation data from C4MIP-type experiments with these models. Independently of the considered scenario, the proposed generalization describes at global scale the reaction of the climate-carbon system to sufficiently weak perturbations. One prediction from this theory is how the time-scale resolved airborne fraction depends on the underlying feedbacks between climate and carbon cycle. These feedbacks are expressed as time-scale resolved functions depending solely on analogues of the α, β, and γ sensitivities, introduced in the generalized framework as linear response functions. In this way a feedback-dependent quantity (airborne fraction) is predicted from feedback-independent quantities (the sensitivities). This is the key relation underlying our study. As a preparatory step, we demonstrate the predictive power of the generalized framework exemplarily for simulations with the MPI Earth System Model. The whole approach turns out to be valid for perturbations up to about 100 ppm CO2 rise above pre-industrial level; beyond this value the response gets nonlinear. By means of the generalized framework we then derive the time-scale dependence of the airborne fraction from the underlying climate-carbon cycle feedbacks for an ensemble of CMIP5 models. Our analysis reveals that for all studied CMIP5 models (1) the total climate-carbon cycle feedback is negative at all investigated time scales; (2) the airborne fraction generally decreases for increasing time scales; and (3) the land biogeochemical feedback dominates the model spread in the airborne fraction at all these time scales. Qualitatively similar results were previously found by employing the original α-β-γ framework to particular perturbation scenarios, but our study demonstrates that, although obtained from particular scenario simulations, they are characteristics of the coupled climate-carbon cycle system as such, valid at all considered time scales. These more general conclusions are obtained by accounting for the internal memory of the system as encoded in the generalized sensitivities, which in contrast to the original α, β, and γ are scenario-independent.

Environmental adaption of rubisco in global marine systems

Marine environments are responsible for 50% of the net primary fixation of carbon globally. Predominantly, the Calvin Benson Basham cycle fixes carbon with the initial enzyme being Rubisco. Rubisco has been shown to be a significant bottleneck in photosynthesis, due to a slow catalytic rate and promiscuity of the enzyme. Previous Rubisco studies have largely focused on land plants, and little is known about the diversity and abundance of Rubisco within marine environments. Through analysing publicly available metagenomes and metatranscriptomes from the Earth’s seas and oceans; we have begun to paint a picture of the global abundance and variation of Rubisco. On top of this, sequence analysis of Rubisco structures provides evidence for adaption of the large and small subunit to differing environments, highlighting residues that diverge in tropical and polar systems. This study expands our knowledge of the Rubisco sequence space and presents opportunities for future engineering projects in economically important plants.

Southeast Asian Mangroves in a Changing World: Insights from Phylogeography, Gene Expression and eDNA Metabarcoding

Mangroves are one of the most threatened ecosystems in the world. Understanding the drivers and limitations of gene flow, phylogeography and genetic adaptation is crucial to effectively manage the threats and conserve the long-term evolutionary potential of mangroves. The first part of this talk summarizes key research findings on the biogeography of major mangrove tree species in Southeast Asia and the greater Indo-West Pacific region. In essence, propagule dispersal capabilities, land barriers and ocean currents are drivers of gene flow and underscores the importance of long-distance dispersal in connecting fragmented mangrove populations. The second part of the talk describes our work on abiotic stress response in mangroves, especially at the species range limits. Current understanding of the molecular mechanism underlying stress adaptation points toward diverging strategies in stress response, even among closely related species. These studies will be important in estimating the adaptive potential of mangroves under climate change. The third part of this talk focuses on recent pstudies on the application of environmental DNA (eDNA) as an effective biomonitoring tool in mangroves. Our findings demonstrated the dynamic distribution of fish species, the transient nature of eDNA in tropical waters, and the importance of bioregionalization in designing global studies.
