Authors: Chen Lin , Guo Hao , Wang Cong , Chen Bin , Sassa Fumihiro , Hayashi Kenshi
Published: January 2024

The spatial distribution of gas emitted from an odor source provides valuable information regarding the composition, size, and localization of the odor source. Surface-enhanced Raman scattering (SERS) gas sensors exhibit ultra-high sensitivity, molecular specificity, rapid response, and large-area detection. In this paper, a SERS gas sensor array was developed for visualizing the spatial distribution of gas evaporated from benzaldehyde and 4-ethylbenzaldehyde odor sources. The SERS spectra of the gas were collected by scanning the sensor array using an automatic detection system. The non-negative matrix factorization algorithm was employed to extract feature and concentration information at each spot on the sensor array. A heatmap image was generated for visualizing the gas spatial distribution using concentration information. Gaussian fitting was applied to process the image for localizing the odor source. The size of the odor source was estimated using the processed image. Moreover, the spectra of benzaldehyde, 4-ethylbenzaldehyde, and their gas mixture were simultaneously detected using one SERS sensor array. The feature information was recognized using a convolutional neural network with an accuracy of 98.21%. As a result, the benzaldehyde and 4-ethylbenzaldehyde odor sources were identified and visualized. Our research findings have various potential applications, including odor source localization, environmental monitoring, and healthcare.
Image-Compression Techniques: Classical and “Region-of-Interest-Based” Approaches Presented in Recent Papers
Authors: Ungureanu Vlad-Ilie , Negirla Paul , Korodi Adrian
Published: January 2024

Image compression is a vital component for domains in which the computational resources are usually scarce such as automotive or telemedicine fields. Also, when discussing real-time systems, the large amount of data that must flow through the system can represent a bottleneck. Therefore, the storage of images, alongside the compression, transmission, and decompression procedures, becomes vital. In recent years, many compression techniques that only preserve the quality of the region of interest of an image have been developed, the other parts being either discarded or compressed with major quality loss. This paper proposes a study of relevant papers from the last decade which are focused on the selection of a region of interest of an image and on the compression techniques that can be applied to that area. To better highlight the novelty of the hybrid methods, classical state-of-the-art approaches are also analyzed. The current work will provide an overview of classical and hybrid compression methods alongside a categorization based on compression ratio and other quality factors such as mean-square error and peak signal-to-noise ratio, structural similarity index measure, and so on. This overview can help researchers to develop a better idea of what compression algorithms are used in certain domains and to find out if the presented performance parameters are of interest for the intended purpose.
Magnetic Sensor Angle Adjustment to Improve Corrosion under Insulation Detection
Authors: Bailey Joseph , Gouws Gideon J. , Long Nicholas
Published: January 2024

A large portion of the pipe infrastructure used in the chemical processing industry is susceptible to corrosion under insulation (CUI). Eddy current-based magnetic sensing is one of the methods that can be used as an early detector of this corrosion. However, the large sensor-to-pipe distances used in this method, due to the presence of insulation, limits the sensitivity to corrosion. This paper will describe the development of instrumentation and methods based on eddy current sensing with thin-film magnetic sensors. In particular, it focuses on the influence of the sensor angle relative to the radial magnetic field. The influence of this parameter on the amplitude of the measured signal was investigated by both finite element simulations and experimental observations. The measured magnetic field was found to be highly sensitive to small changes in sensor angle, with the estimated depth of a defect changing at a rate of 11.2 mm/degree of sensor rotation for small angles. It is also shown that a sensor aligned with the radial direction should be avoided, with an optimal sensor angle between 0.5 and 4 degrees. With the sensor in this angle range, the simulations have shown it should be possible to resolve the depth of corrosion to a resolution of 0.1 mm.

Authors: Bekteshi Venera , Bellamy Jennifer L.
Published: January 2024

Objective: This study investigates the influence of acculturative stress on the mental well-being of Cuban-born women and Latina immigrants, emphasizing their distinctive experiences. Methods: Utilizing data from the National Latino Asian American Study (NLAAS), a comprehensive nationwide mental health investigation among Latino and Asian Americans, this study examined 264 Cuban women (average age: 58) who migrated to the United States and live in south Florida. The study employed Family Stress Management (FSM) framework and Bekteshi et al.’s Contextual Influence on Acculturative Stress (CIAS) framework to scrutinize the interplay of contextual factors and individual characteristics impacting adolescents’ psychological distress. Results: The findings revealed several noteworthy associations. Higher levels of church attendance, challenges in visiting family overseas, and perceived racial discrimination correlated with elevated stress levels. Furthermore, the age at which individuals immigrated was positively linked to increased stress (b = 0.18; p = 0.04), indicating that older Cuban immigrants experienced greater psychological distress upon their arrival in the United States. Additionally, higher levels of conflict between family and cultural values, as well as intensified religious beliefs, were associated with elevated distress levels. Conclusion: This study underscores the intricate interplay of diverse contextual factors in shaping the mental health and well-being of Cuban-born women. The insights derived from this research have implications for the development of tailored interventions and support systems, aiming to address the unique needs of this population.

Published: January 2024

China’s proposed double carbon goal makes it urgent to promote green consumption and green lifestyles. The present study selected separate economic indicators of urban and rural areas and assigned different weights in the construction of a green consumption indicator system. Based on data from 30 provinces (excluding Tibet) between 2003 and 2019, this study investigated the connections between green consumption, environmental regulations, and carbon emissions, analyzing their mechanism. This study found that green consumption will reduce anthropogenic carbon emissions in the short term but will result in low carbon emissions in the long term. Environmental rules have a definite long-term impact on green consumption, as evidenced by the “U”-shaped trend they follow. Second, this study found that the level of green consumption exhibits a rising and then falling trend on the vegetation’s capacity to sequester carbon, and the impeding force will become stronger over time. Third, this study found that green consumption innately has a degree of inertia and self-enhancement bias.
Agriculture in Protected Areas of Latin America: News Website Review
Authors: Verjel Martha Cecilia Vergel , Vieira Thiago Almeida
Published: January 2024

There is a close relationship between agriculture and protected areas/conservation units, because the main activity in most human settlements in these areas is agriculture, which depending on the management and type of crop can benefit or affect said territories. The purpose of this study is to analyze the relationship between agriculture and protected areas/conservation units in Latin America, as it reveals the weaknesses or strengths that influence conservation objectives. A systematic review of articles published in the media on agriculture in protected areas/conservation units in Latin America was conducted. The results of the news analysis were supported by scientific information endorsed by different authors, revealing a common pattern in most Latin American countries, with similar contexts based on the exploitation of natural resources and the development of social conflicts (illegal activities, state negligence, and corruption), as well as the existence of projection in management and good agricultural practices. The result was an evident lack of governance and control by responsible authors with objectives other than conservation. However, there is an effort to achieve a harmonious relationship between human activities and the conservation of areas, aimed at finding alternatives that mitigate socio-environmental impacts. Finally, the results provide an analysis that unifies scientific information from different authors and current news material, generating wide, varied, and reliable information that improves scientific literature.

The ciliate Climacostomum virens produces the metabolite climacostol that displays antimicrobial activity and cytotoxicity on human and rodent tumor cells. Given its potential as a backbone in pharmacological studies, we used the fruit fly Drosophila melanogaster to evaluate how the xenobiotic climacostol affects biological systems in vivo at the organismal level. Food administration with climacostol demonstrated its harmful role during larvae developmental stages but not pupation. The midgut of eclosed larvae showed apoptosis and increased generation of reactive oxygen species (ROS), thus demonstrating gastrointestinal toxicity. Climacostol did not affect enteroendocrine cell proliferation, suggesting moderate damage that does not initiate the repairing program. The fact that climacostol increased brain ROS and inhibited the proliferation of neural cells revealed a systemic (neurotoxic) role of this harmful substance. In this line, we found lower expression of relevant antioxidant enzymes in the larvae and impaired mitochondrial activity. Adult offsprings presented no major alterations in survival and mobility, as well the absence of abnormal phenotypes. However, mitochondrial activity and oviposition behavior was somewhat affected, indicating the chronic toxicity of climacostol, which continues moderately until adult stages. These results revealed for the first time the detrimental role of ingested climacostol in a non-target multicellular organism.

Published: January 2024

The freshwater water flea (Daphnia magna Straus, 1820) is prey for numerous predators. Yet it possesses a wide range of strategies to defend itself against predation. The aim of this work is to investigate the defensive mechanisms employed by D. magna to reduce predation by the coelenterate Hydra viridissima, and two planarians, Polycelis felina and Dugesia gonocephala. To do this, we used a freshwater microcosm. An additional aim is to investigate interactions with the presence of the isolated endosymbiotic algae from green hydra, thus combining and observing the interaction of the zooplankton and microalgal component. Each experiment included five replicates (13.5 °C, 25 °C), in crystallizing glass containers (60 mL volume, 60 mm diameter, 35 mm height), including satiated (fed with larvae of Artemia salina) and starved predators, respectively (one or five individuals of a particular predator species in one microcosm). As the isolated microalgae are unique, we tracked the following three mechanisms of Daphnia defense for the first time including precisely this microalgal component: (i) grouping (visual magnification), i.e., two or more Daphnia holding together; (ii) the phenomenon of overproduction, i.e., any number of Daphnia in one container above the 10 initially added individuals; and (iii) accelerated movement (“bullet movement”), i.e., high-speed movements in particular microcosms. The results provide new information for a better understanding of the interspecific relationships in systems that include both zooplankton and microalgal components.

Safeguarding drinking water is a major public health and environmental concern because it is essential to human life but may contain pollutants that can cause illness or harm the environment. Therefore, continuous research is necessary to improve water treatment methods and guarantee its quality. As part of this study, the effectiveness of coagulation–flocculation treatment using aluminum sulfate (Al2(SO4)3) was evaluated on a very polluted site. Samplings were taken almost every day for a month from the polluted site, and the samples were characterized by several physicochemical properties, such as hydrogen potential (pH), electrical conductivity, turbidity, organic matter, ammonium (NH+4), phosphate (PO43−), nitrate (NO3−), nitrite (NO2−), calcium (Ca2+), magnesium (Mg2+), total hardness (TH), chloride (Cl−), bicarbonate (HCO3−), sulfate (SO42−), iron (Fe3+), manganese (Mn2+), aluminum (Al3+), potassium (K+), sodium (Na+), complete alkalimetric titration (TAC), and dry residue (DR). Then, these samples were treated with Al2(SO4)3 using the jar test method, which is a common method to determine the optimal amount of coagulant to add to the water based on its physicochemical characteristics. A mathematical model had been previously created using the support vector machine method to predict the dose of coagulant according to the parameters of temperature, pH, TAC, conductivity, and turbidity. This Al2(SO4)3 treatment step was repeated at the end of each month for a year, and a second characterization of the physicochemical parameters was carried out in order to compare them with those of the raw water. The results showed a very effective elimination of the various pollutions, with a very high rate, thus demonstrating the effectiveness of the Al2(SO4)3. The physicochemical parameters measured after the treatment showed a significant reduction in the majority of the physicochemical parameters. These results demonstrated that the coagulation–flocculation treatment with Al2(SO4)3 was very effective in eliminating the various pollutions present in the raw water. They also stress the importance of continued research in the field of water treatment to improve the quality of drinking water and protect public health and the environment.

Published: January 2024

The aim of this study was to assess the impact of WWTP effluents on the sediment microbial communities throughout the Mureș River. This study shows the existence of an ecological equilibrium between the WWTP effluent disruptors and the resilience of the Mureș River sediment microbiomes, a fact that suggests the river’s stable/balanced ecological status in this regard, partly due to the microbial communities’ resilience to the local impact of WWTP effluents. High-throughput 16S bacterial metabarcoding was used to evaluate the bacterial communities in the sediment. Due to the lotic system’s sediment microbial communities’ sensitivity to environmental changes, we assumed the dependency of these community structures and functions on environmental abiotic and abiotic parameters. The study results show that, although bacterial communities are equally diverse in the three locations (upstream WWTP, WWTP effluents, and downstream WWTP), there is a difference in community structure between the upstream samples and the WWTP samples, while the downstream samples contain a mixture of the upstream and WWTP effluent communities. Just downstream of the WWTP sediment, microbial communities are influenced by the specific input from the WWTP effluents; nevertheless, the river sediment microbiome is resilient and able to further recover its natural microbial composition, as evidenced by the similarity in bacterial community structures at all upstream river locations. This study demonstrates the ecological equilibrium between the WWTP effluent disruptors and the resilience capacity of the Mureș River sediment microbiomes, a fact that indicates the river’s stable/balanced ecological status, in part due to the microbial communities’ resilience to the local impact of WWTP effluents. Based on these findings, a monitoring system should be implemented here in the future.

Published: January 2024

In 18 Interviews mit Unternehmenslenkerinnen und -lenkern während der Coronapandemie wurde deutlich, dass auf der einen Seite die Persönlichkeit der Führungskraft an der Spitze einer Organisation und auf der anderen Seite der ≫Charakter≪ der Organisation eine wichtige Rolle bei der Bewältigung einer Krise spielen. Beide Charaktere sollten bereits vor Ausbruch einer Krise weitgehend gefestigt sein und optimal zusammenspielen. Aufseiten der Organisation gehören dazu insbesondere eingeübte Krisenmanagement-Prozesse, klare Rollen und Verantwortlichkeiten sowie eine Kultur des Vertrauens und Miteinander-Lernens. Die Leadership-Persönlichkeit sollte ein stabiles Wertegerüst haben, Empathie und Haltung zeigen, Zuversicht ausstrahlen und Visionen vermitteln können. Da während einer Krise der Fokus zwangsläufig auf kurzfristigen operativen Maßnahmen wie dem Kostenmanagement liegt, muss die strategische Entwicklung des Unternehmens ebenso wie die kulturelle Transformation unabhängig von Krisen gezielt gesteuert werden, um über die akute Existenzsicherung hinaus langfristig Zukunftssicherung zu betreiben.

Published: January 2024

In the contemporary global landscape, characterised by increasing concerns about climate change, sustainable development, and corporate responsibility, it is necessary to study and address pressing issues at the intersection of environmental consciousness, technological advancement, and governance practices. This paper aims to examine the relationship between the environmental, social, and governance (ESG) pillars of a country’s development, green brand and digitalisation. To achieve the study’s goal, partial least squares structural equation modelling (PLS-SEM) was applied. The object of investigation was EU countries for 2016-2020. The findings allow us to conclude that a country's green brand is conducive to ESG performance by attracting green investment in renewable energies, social projects, and innovations. The results confirm that governments should prioritise sustainability initiatives, such as investing in renewable energy, adopting sustainable practices, and implementing environmental and social policies. Such efforts can enhance a country's green brand and lead to positive ESG outcomes, attracting more responsible businesses and investors. Moreover, digitalisation promoted governance by 0.142. The results showed that digitalisation could be a powerful tool for improving a country's green brand and ESG performance. Digital technologies can help countries monitor and manage environmental resources, promote sustainable practices, and engage with stakeholders.
Role of Inter-site Hubbard Interactions in MnS Monolayer: DFT+U+V Investigation
Authors: Abdullahi Yusuf Zuntu
Published: January 2024

The stable MnS monolayer was recently predicted using first-principles density functional theory (DFT) including Hubbard U (DFT+U) correction and Monte Carlo (MC) simulations. It is shown to exhibit an indirect band gap of 0.68 eV semiconductor with a high Neel temperature (T_N) of 720 K and an in-plane easy axis magnetic anisotropy energy (MAE). The considered on-site Hubbard U correction takes into account only the Mn (3d) localized nature. To correct the inter-site errors due to strong hybridization between bonded Mn (3d) and S (2p) states, the Hubbard +V inter-site parameter should be added to the calculations. In this study, the band gap of MnS is found to be increased to 1.24 eV (twice that for DFT+U) after considering the inter-site V correction (DFT+U+V). Since the MnS monolayer prefers an in-plane easy axis for the MAE, the estimated Berezinskii Kosterlitz Thouless transition (BKT) transition temperature is as high as 1667.8 K. The carrier mobility is calculated based on the deformation potential and effective mass and it is found that holes (2.12 〖cm〗^2 v^(-1) S^(-1)) are twice the size of these electrons (1.21 〖cm〗^2 v^(-1) S^(-1)). The results are expected to improve the potential of the MnS monolayers in multiple AFM spintronic device applications.

Published: January 2024

This paper presents the frequency characteristics of a barometric pressure-sensing wave height sensor employing a MEMS piezoresistive cantilever and a micromesh waterproof film. The proposed sensor exhibited mechanical bandpass filter characteristics owing to air leakage around the cantilever and film. Consequently, high robustness can be achieved if the frequency is designed to match the wave range. We theoretically and experimentally verified that the frequency response is influenced by the film’s chamber volume and permeability constant. We demonstrated that the proposed frequency-response model helps design a waterproof wave height sensor using a cantilever-type differential pressure sensor.

The Concept and Relevance of the Cycle of Creation through Sacrifice in the Bhagavad Gita
Authors: Mittal Ayush
Published: January 2024

In the current era, the escalation of immoral behavior in the world can be attributed to health challenges and limited mental acuity. Individuals often engage in egregious transgressions without a moment's reflection. For contemporary humanity, personal happiness has become the essence of life. Nevertheless, it is imperative for individuals to comprehend that their ultimate self-interest is intertwined with the welfare of society. The one who orchestrates the well-being of others finds their own tribulations diminished. The conceptual framework of the creation cycle as expounded in the Bhagavad Gita enlightens us about the necessity for humans to contribute by diligently executing their duties. To refrain from immoral conduct and foster mutual welfare, it is imperative for us to incorporate the principles of the creation cycle into our lives.

वर्तमान समय में स्वास्थ्य एवं संकीर्ण मानसिकता के कारण संसार में पापाचरण बढ़ता जा रहा है। घनिष्ठ अपराधों को करने से पहले कोई भी एक क्षण के लिए भी नहीं विचार करता। वर्तमान मनुष्य के लिए मात्र अपना सुख ही जीवन का सार बन गया है। परंतु मनुष्य को यह समझने की आवश्यकता है कि लोकहित में ही उसका परम स्वार्थ निहित है। जो दूसरों के सुखों की व्यवस्था करता है उसके कष्ट स्वयं ही नष्ट हो जाते हैं। श्रीमद्भगवद्गीता में वर्णित सृष्टि-चक्र की अवधारणा से हमें यह ज्ञात होता है कि लोक कल्याण के लिए मनुष्यों को उसमें अपना योगदान देने की आवश्यकता है जिसके लिए उसे अपने कर्तव्य-कर्मों का निर्वाह करना होगा। पापाचरण से बचने के लिए एवं परस्पर कल्याण के लिए हमें सृष्टि-चक्र के सिद्धांतों को अपने जीवन में उतारने की आवश्यकता है।
La rivoluzione del mondo
Authors: Emmenegger Camilla
Published: January 2024

Max Weber never developed a comprehensive theory of political revolution. Yet, his work is scattered with references to revolutionary actors: religious fanatics, diehard idealists, anarcho-insurrectionists, successful people’s leaders. Figures who set themselves against the world with violence, in order to achieve justice on earth or bear witness to their principles. Although intermittent, Weberian reflection on revolutionary subjectivity questions the relationships between politics, ethics and violence in a novel combination. This volume delves into Weber’s accurate and fascinating frescoes of the subjective paths that lead to an attitude of world revolution; and, it introduces an unusual portrait of the German sociologist, in partial contrast to the famous representation of the bourgeois with class consciousness.
Investigating the Spatio-Temporal Relationship between NDVI and LST in Abakaliki LGA, Ebonyi State Nigeria, Using Landsat and Correlation Analysis: Implications for Landscape Management
Authors: E Onuegbu Francis
Published: January 2024

Understanding spatiotemporal linkages between normalised difference vegetation index (NDVI) and land surface temperature (LST) is crucial for managing landscape resilience amid global change. This study applied correlation analyses to investigate NDVI-LST relationships across Abakaliki LGA, Nigeria from 2000-2022 using Landsat data. Multi-decadal trends revealed widespread LST increases exceeding 9°C, while NDVI declined, implying vegetation clearing transformed surfaces from carbon sinks to sources dampening temperatures. In 2000, NDVI positively correlated with LST (r=0.745, p<0.01); by 2022, large-scale NDVI suppression drove strong negative correlations between NDVI and LST (r=-0.751, p<0.01). Findings documented rapid decoupling of previously heterogeneous NDVI-LST couplings tied to diverse land use. Sustainable intensification offers potential to restore climate-buffering vegetation and recouple local anthropogenic-climatic systems. Continued monitoring can track restoration progress while adaptation evolves with socio-environmental change. This research advances understanding of anthropic impacts on landscape energetics using remote sensing and correlation analyses, with implications for integrated management under global change.
Impact Assessment of Vehicular Poly-Aromatic Hydrocarbon Emmissions on Cassava Leaves and Tubers along Owerri – Port Harcourt Highway, Nigeria
Authors: M Ebulue, M. , C Okoye, A.
Published: January 2024

Poly-aromatic hydrocarbon (PAH) effluents arising from vehicular spent petroleum products on highways were assessed. Analysis of this impact on cassava leaves and tubers on highway using the method of AOAC, 1990 revealed xylene to be of highest concentration, 0.1449 and 0.1865mm/g in leaves and roots respectively. Other PAHs analyzed were found to contain as follows: acenapthylene (0.0003 and 0.0312mm/g), phenanthlene (0.0029 and 0.0003mm/g), anthracene (0.0067 and 0.0127mm/g), 1,2-benzathracene (0.0161 and 0.0126mm/g), benzo(k)fluorine (0.0001 and 0.223mm/g) and pyrene (0.0169 and 0.0329mm/g) for leaves and roots respectively. From these findings, the concentration of PAH is highest in cassava roots than leaves and this justifies its hazardous effects on humans. Therefore, environmental monitoring of poly aromatic hydrocarbons in food is imperative in evaluating the possible toxicity of the impact as well as the carcinogenic potential of these compounds to humans via intake.
