This study examines the dynamic relationship between carbon markets and clean energy stocks using a quantile Granger-causality framework, capturing nonlinear dependencies across different market conditions. Unlike conventional mean-based approaches, this method identifies asymmetric causal linkages, particularly during periods of extreme market movements. Empirical results reveal a bidirectional Granger-causal relationship between carbon price returns and clean energy stock returns, predominantly at the lower quantile τ=0.25 and upper quantile τ=0.75 of the conditional distribution. This indicates that carbon price fluctuations significantly impact clean energy investments during bullish (>0.50 quantiles) and bearish (<0.50 quantiles) trends, while the effect is weaker during stable periods (0.50 quantile). Additionally, findings suggest that the impact of carbon pricing varies across regions. While the signs of the Granger-causality running from carbon markets to clean energy stocks are less than 0 in global, European, and U.S. markets, China’s policy-driven sustainability initiatives mitigate these risks, enhancing investment stability. These findings underscore the importance of region-specific carbon policies in supporting clean energy growth. Policymakers should consider stabilization mechanisms in volatile markets and strategic carbon pricing to optimize investment incentives. Future research should explore the role of green financial innovations in enhancing carbon market efficiency and reducing investment uncertainty in clean energy transitions. Full article

Growth hormone-releasing hormone (GHRH) antagonists exert antitumor functions in different experimental cancers. However, their role in combination with radiotherapy in non-small cell lung cancer (NSCLC) remains unknown. Therefore, we investigated the radiosensitizing effect of GHRH antagonists in NSCLC. A549 and H522 NSCLC cell lines were exposed to ionizing radiation (IR) and GHRH antagonists MIA-602 and MIA-690, either individually or in combination. Cell viability and proliferation were evaluated by MTT, BrdU, flow cytofluorimetry, and clonogenic assays; gene and protein expression, signaling pathways, and apoptosis were analyzed by real-time PCR, Western blot, annexin staining, and caspase-3 assay. GHRH antagonists showed antitumor effects alone and potentiated IR-induced inhibition of cell viability and proliferation. The combination of MIA-690 and IR decreased the expression of GHRH receptor, its oncogenic splice variant 1, and IGF1 mRNA levels. Additionally, cell cycle inhibitors and proapoptotic markers were upregulated, whereas cyclins, oncogenic MYC, and the antiapoptotic protein Bcl-2 were downregulated. Radioresistance was prevented by MIA-690, which also blunted epithelial–mesenchymal transition by enhancing E-cadherin and reducing mesenchymal, oxidative, and proangiogenic effectors. Finally, both MIA-602 and MIA-690 enhanced radiosensitivity in primary human NSCLC cells. These findings highlight the potential of GHRH antagonists as radiosensitizers in NSCLC treatment.

The paper considers queuing networks with prohibitions on transitions between network nodes that determine the protocol of their operation. In the graph of transient network intensities, a set of base vertices is allocated (proportional to the number of edges), and we raise the question of whether some subset of it can be deleted such that the stationary distribution of the Markov process describing the functioning of the network is preserved. In order for this condition to be fulfilled, it is sufficient that the set of vertices of the graph of transient intensities, after the removal of a subset of the base vertices, coincide with the set of states of the Markov process and that this graph be connected. It is proved that the ratio of the number of remaining base vertices to their total number n converges to one-half for n. In this paper, we are looking for graphs of transient intensities with a minimum (in some sense) set of edges for open and closed service networks. Full article

To address the challenge of heat transfer enhancement in the condensation of steam with non-condensable gases on a vertical wall under natural convection conditions, an improved boundary layer model with coupled multi-physics field was proposed in this paper, and traditional theoretical limitations were broken through by innovations. The particle swarm optimization algorithm was first introduced into the solution of the condensation boundary layer, and the convergence difficulty in the laminar–turbulent transition region under infinite boundary conditions was overcome. A coupled momentum–energy–mass equation system that simultaneously considered temperature–concentration dual-driven gravity terms and liquid film drag–suction dual effects was established, and higher computational efficiency and accuracy were achieved. A new mechanism where the concentration boundary layer dominated heat transfer resistance under the coupled action of the Prandtl number (Pr) and Schmidt number (Sc) was revealed. Experimental validation demonstrated that a prediction error of less than 5% was exhibited by the model under typical operating conditions of passive containment cooling systems (pressures of 1.5–4.5 atm and subcooling temperatures of 14–36 °C), and a theoretical tool for high-precision condensation heat transfer design was provided.

Moroccan vegetation faces significant pressure particularly from human activities and climate change, while most ecosystems lack detailed assessments. Phytoecological studies and species assessments are implemented using vegetation sampling, analysis of climate data, geological substrate maps, and the Digital Elevation Model (DEM). The study area hosts 565 plant species distributed into 74 families, with Asteraceae being the most abundant family, representing 17.7%. In addition, the correspondence analysis test demonstrates that species are grouped into six distinct blocks. Block 1 comprises a set of Quercus ilex forests. Block 2 encompasses Juniperus phoenicea lands and transition zones between Quercus ilex and Juniperus phoenicea. Block 3 represents Pinus halepensis forests and pine occurrences within Quercus ilex and Juniperus phoenicea stands. Block 4 indicates the emergence of xerophytic species alongside the aforementioned species; it forms the upper limits of Blocks 1, 2, and 3. Block 5 corresponds to formations dominated by Juniperus thurifera in association with xerophytes. Block 6 groups together a set of xerophytic species characteristic of high mountain environments. Additionally, Quercus ilex colonizes the subhumid zones and prefers limestone substrates, Juniperus phoenicea and Tetraclinis articulata, and Pinus halepensis occupies the hot part of the semi-arid in limestone, clays, and conglomerates, while the Juniperus thurifera and xerophytes inhabit the cold parts and limestone substrates. The thermo-Mediterranean vegetation level occupies low altitudes, dominated by Tetraclinis articulata, Juniperus phoenicea, and Olea europaea. The meso-Mediterranean level extends to intermediate altitudes, dominated by Quercus ilex and Juniperus phoenicea. While the supra-Mediterranean level is dominated by Quercus ilex, Arbutus unedo, and Cistus creticus. The mountain Mediterranean level, located in the high mountains, is dominated by Juniperus thurifera associated with xerophytes. Finally, the oro-Mediterranean level, found at extreme altitudes, is dominated by xerophytes. Some species within this region are endemic, rare, and threatened. Consequently, the implementation of effective conservation and protection policies is recommended. Full article

This study aimed to evaluate Romanian university students’ perceptions of career counseling and guidance (CCG) services provided in 2022–2023. A quantitative methodology was employed, analyzing survey data (n = 7402 respondents from 18 universities) to explore awareness of, utilization of, and satisfaction with such services. Data analysis via SPSS included descriptive statistics (mean, median, standard deviation), bivariate correlations (Pearson, Spearman), and Chi-Square tests to identify significant relationships between variables, such as academic year, knowledge of CCG staff/services, and overall service evaluation. Preliminary results suggest low rates of CCG awareness and use, highlighting a disparity between student needs and available resources. This study contributes to understanding the Romanian CCG context by integrating theoretical perspectives from the international literature on dropout prevention, workforce adaptability in the digital age, and higher education quality assurance models. Limitations regarding reliance on secondary data and subjective response biases are discussed, and directions for future research aimed at improving CCG efficacy and student career transition support are proposed. Complete findings will be presented in the full work, providing an empirical foundation for CCG policy and strategy development aimed at enhancing career guidance services in Romanian higher education.

Pre-study tests and strain measurements of critical structural components in high-temperature environments are paramount. In the field of high-temperature strain measurement, the contact strain measurement method has the widest application range, a high measurement accuracy, and a low cost. At present, a variety of high-temperature strain gauges have been developed at home and abroad. However, due to material and processing process limitations, the research on high-temperature strain gauges applied above 800 °C is still relatively small and immature. Therefore, it is very necessary to do a systematic analysis of the research in this field. This paper describes the basic principle and structure of high-temperature strain gauges and systematically analyses and summarizes the current research status of high-temperature strain gauges’ sensitive grids, protective layers, and transition layers in terms of materials and structures. Finally, based on the existing research, it provides ideas and prospects for future contact strain measurement methods applied to higher temperatures. Full article

The process of ultrasonic atomization involves a series of dynamic/topological deformations of free surface, though not always, of a bulk liquid (initially) below the air. This study focuses on such dynamic interfacial alterations realized by changing some acousto-related operating conditions, including ultrasound excitation frequency, acoustic strength or input power density, and the presence/absence of a “stabilizing” nozzle. High-speed, high-resolution imaging made it possible to qualitatively identify four representative transitions/demarcations: (1) the onset of a protrusion on otherwise flat free surface; (2) the appearance of undulation along the growing protuberance; (3) the triggering of emanating beads fountain out of this foundation-like region; and (4) the induction of droplets bursting and/or mist spreading. Quantitatively examined were the two-parameters specifications—on the degrees as well as induction—of the periodicity in the protrusion-surface and beads-fountain oscillations, detected over wider ranges of driving/excitation frequency (0.43–3.0 MHz) and input power density (0.5–10 W/cm2) applied to the ultrasound transducer of flat surface on which the nozzle was either mounted or not. The resulting time sequence of images processed for the extended operating ranges, regarding the fountain structure pertaining, in particular, to recurring beads, confirms the wave-associated nature, i.e., their size “scalability” to the ultrasound wavelength, predictable from the traveling wave relationship. The thresholds in acoustic conditions for each of the four transition states of the fountain structure have been identified—notably, the onset of plausible “bifurcation” in the chain-beads’ diameter below a critical excitation frequency.

The transition to a circular economy is imperative in order to confer considerable benefits upon the environment, the economy, and society. The present study aimed to analyse the interdependence and causal relationships between recyclable material consumption as the dependent variable and other independent variables, including the raw material footprint, the trade in recyclable materials, greenhouse gas emissions, investments in the circular economy sectors, the real GDP per capita, renewable energy sources, the circular material use rate, and the population within the 27 EU Member States from 2013 to 2021. In order to achieve the objective, a two-stage economic model was constructed using a panel approach. The research findings indicate a direct and positive correlation between the consumption of recyclable materials and all the aforementioned independent variables, with the exception of greenhouse gas emissions. This study confirms that innovation and investment significantly reduce environmental degradation, and, moreover, the efficiency of investment remains unaffected. A further relationship that emerged from this study is that developed countries have higher resource consumption, which is consistent with the cause of increased consumption being the rapid growth of the middle class around the world. The main conclusion is that Europe cannot achieve sustainable development without a circular economy. Full article

The increasing demand for sustainable materials in automotive applications, coupled with the critical need to address marine plastic pollution, presents an opportunity for innovative material development. This study explores composites made from recycled polyamide 6 (PA6) fishing nets reinforced with switchgrass fibers (0–30 wt%). The composite with 30 wt% switchgrass fibers increased tensile strength by 23% and Young’s modulus by 126% compared to unreinforced recycled PA6, achieving 93% of the tensile strength of commercial automotive-grade neat PA6 and surpassing another grade by 22%. However, higher fiber loading hindered processability, as evidenced by incomplete mold filling and reflected by a decrease in melt flow rate from 19.35 to 8.63 g/10 min. Thermal analysis revealed reduced crystallinity and crystallization temperatures with fiber addition, attributed to restricted polymer chain mobility. While dynamic mechanical analysis demonstrated improved stiffness below the glass transition temperature, scanning electron microscopy indicated optimal fiber-matrix adhesion at up to 20 wt% fiber loading, with aggregation at higher concentrations. These findings establish recycled fishing net-derived PA6/switchgrass fiber composites as a viable alternative to virgin materials in automotive applications, with mechanical properties comparable to commercial grades. Although the composites demonstrate enhanced mechanical strength and modulus, the significant reduction in ductility restricts their use to rigid, semi-structural components where flexibility is not critical. Future research should address processing challenges to enhance fiber dispersion and interfacial adhesion at higher loadings. Full article

Low-temperature Fischer–Tropsch (LTFT) synthesis converts syngas to diesel/wax at 200–250 °C. The LTFT reaction has recently received renewed interest, as it can be used for converting syngas from renewable sources (biomass and waste) to high-value fuels and chemicals. Conventional LTFT reactors, such as fixed-bed and slurry reactors, are not entirely suitable for bio-syngas conversion due to their smaller scale compared to fossil fuel-based syngas processes. This review explores advancements in intensifying LTFT reactors suitable for bio-syngas conversion, enabling smaller scale and dynamic operation. Various strategies for enhancing heat and mass transfer are discussed, including the use of microchannel reactors, structured reactors, and other designs where either one or both the heat and mass transfer are intensified. These technologies offer improved performance and economics for small LTFT units by allowing flexible operation, with increased syngas conversion and reduced risk of overheating. Additionally, this review presents our outlook and perspectives on strategies for future intensification. Full article

The initiation and specification of germline cells are crucial for plant reproduction and the continuity of species. In Arabidopsis thaliana, auxin plays a vital role in guiding the transition of somatic cells into germline fate, orchestrating the specification of both male archesporial cells and female megaspore mother cells. This process is regulated through interaction with the transcription factor Sporocyteless/Nozzle, which forms a feedback mechanism that modulates germ cell specialization. Auxin biosynthesis, polar transport, and signal transduction pathways collectively ensure the accurate determination of germ cell fate. Furthermore, the coordination of auxin signaling with epigenetic regulation and miRNA-mediated control fine-tunes the differentiation between germline and somatic cells. This review discusses the mechanisms underlying auxin-guided germ cell specification. It proposes future research directions, including studies on PIN-FORMED-mediated polar transport, the role of the YUCCA family in auxin biosynthesis, and the involvement of the Transport Inhibitors Response 1/Auxn Signaling F-Box-Auxin Response Factor (TIR1/AFB-ARF) signaling pathway in germ cell fate determination. These insights will enhance our understanding of plant reproductive biology and provide new strategies for crop breeding. Full article

The Ramsey approach is applied to analyses of the kinematics of systems built of non-relativistic, motile point masses/particles. This approach is based on colored graph theory. Point masses/particles serve as the vertices of the graph. The time dependence of the distance between the particles determines the coloring of the links. The vertices/particles are connected with orange links when particles move away from each other or remain at the same distance. The vertices/particles are linked with violet edges when particles converge. The sign of the time derivative of the distance between the particles dictates the color of the edge. Thus, a complete, bi-colored Ramsey temporal graph emerges. The suggested coloring procedure is not transitive. The coloring of the links is time-dependent. The proposed coloring procedure is frame-independent and insensitive to Galilean transformations. At least one monochromatic triangle will inevitably appear in the graph emerging from the motion of six particles due to the fact that the Ramsey number R(3,3)=6. This approach is extended to the analysis of systems containing an infinite number of moving point masses. An infinite monochromatic (violet or orange) clique will necessarily appear in the graph. Applications of the introduced approach are discussed. The suggested Ramsey approach may be useful for the analysis of turbulence seen within the Lagrangian paradigm. Full article

Optimization has become an indispensable tool in the food industry, addressing critical challenges related to efficiency, sustainability, and product quality. Traditional approaches, such as one-factor-at-a-time analysis, have been supplanted by more advanced methodologies like response surface methodology (RSM), which models interactions between variables, identifies optimal operating conditions, and significantly reduces experimental requirements. However, the increasing complexity of modern food production systems has necessitated the adoption of multi-objective optimization techniques capable of balancing competing goals, such as minimizing production costs while maximizing energy efficiency and product quality. Advanced methods, including evolutionary algorithms and comprehensive modeling frameworks, enable the simultaneous optimization of multiple variables, offering robust solutions to complex challenges. In addition, artificial neural networks (ANNs) have transformed optimization practices by effectively modeling non-linear relationships within complex datasets and enhancing prediction accuracy and system adaptability. The integration of ANNs with Industry 4.0 technologies—such as the Internet of Things (IoT), big data analytics, and digital twins—has enabled real-time monitoring and optimization, further aligning production processes with sustainability and innovation goals. This paper provides a comprehensive review of the evolution of optimization methodologies in the food industry, tracing the transition from traditional univariate approaches to advanced, multi-objective techniques integrated with emerging technologies, and examining current challenges and future perspectives.

The present article analyses the theme of circularity in the fashion industry, with particular attention to the role of technology in favoring the adoption of circular economic models. The article explores the role of technology in supporting the circular economy in the fashion industry, focusing on the implementation of circular business models by three companies: SHEIN, Ralph Lauren, and Cotopaxi. The aim is to investigate the challenges and opportunities associated with the adoption of circular economy practices in an industry known for its environmental impact. The research highlights how technology, particularly software such as Materia MX, can facilitate streamlined supply chains, reduced waste, and optimized resource efficiency, thus, overcoming obstacles such as high investment costs and supply chain complexities. The case studies demonstrate how each company has integrated circular practices, such as recycling, reusing materials, and improving transparency through technologies such as AI, blockchain, and IoT, to promote sustainability. Thus, the study emphasizes the importance of technological innovation in enabling a more sustainable and circular future for the fashion industry while addressing challenges related to consumer awareness, regulatory pressures, and infrastructure. The results suggest that technology is a key factor in the fashion industry’s transition to a circular economy, offering a competitive advantage and facilitating the achievement of environmental objectives.
