Son cada vez más numerosos los estudios que huyen de cualquier pretensión de generalidad para centrar su atención en elementos específicos del teatro del Siglo de Oro en alguna de sus dimensiones, sintácticas, semánticas o sociológicas, pero son menos los que se consagran enteramente y por extenso a uno de dichos aspectos, como hace Javier Salazar Rincón con el tipo del alcalde villano en la presente monografía. El libro, disponible exclusiva y gratuitamente en formato digital, versa en efecto sobre ese personaje, pero pronto el alcalde rústico deviene el “aleph” por el que se filtran las demás realidades del contexto extraliterario que permiten al autor abundar no solo en la gramática del personaje, sino en las diversas coordenadas pragmáticas de su desarrollo y recepción. En este sentido, la variedad de perspectivas considerada se articula en torno a la noción de “signo múltiple” (advertida desde la introducción), de carácter proteico, moldeable en un contexto, y perfectamente aplicable al tipo del alcalde, que recibe los condicionantes del entorno sociohistórico tanto como repercute sobre las estructuras de su tiempo. Consecuentemente, el afán integrador del estudio rebasa los límites convencionales de la cronología del Siglo de Oro y extiende con frecuencia el análisis al siglo XVIII, cuando no avanza todavía más.

En el imaginario colectivo, la filología suele entenderse como una de las ciencias auxiliares de la historia. La realidad es que la lengua es un dibujo del pasado, su fotografía, que conforma los pilares con los que se construye el futuro.
Vemos a través de la realidad del siglo XXI, cuyo primer cuarto viene marcado por la velocidad catalizada de las revoluciones tecnológicas ligadas a los avances en la computación. La sociedad de consumo que lo constituye entiende esta velocidad como su modus vivendi, en la que lo efímero es la norma y necesita beber del Árbol de las Humanidades para saciar esta sed de lo inmediato, que está desembocando en un futuro incierto, insostenible y, por consecuencia, finito. Este monográfico nace justo de la necesidad de dialogar en el presente para aportar un pequeño grano de arena contra la destrucción del futuro.
A longitudinal rat forelimb model for assessing in vivo neuromuscular function following extremity reperfusion injury

Published: January 2025

Rhabdomyolysis following revascularization of the ischemic upper extremity can lead to life- & limb- threatening sequelae. In the context of replantations and vascularized composite allografting, a reconstructive procedure usually reserved for upper limb amputees, prolonged tissue ischemia is detrimental to extremity functional recovery. Currently, validated survival small animal models of extremity reperfusion injury that permit longitudinal assessment of limb function are lacking. To date, studies that evaluated reperfusion injury-induced neuromuscular impairment rely on terminal ex vivo procedures and do not provide clinically translatable measurements. Furthermore, it is unclear if upper extremity musculature exhibits a different ischemic threshold compared to the lower limb given the relatively rare incidence of upper limb ischemia. Here, we present a reliable rat model of extremity post-reperfusion syndrome (PRS) that comprehensively recapitulates the biochemical hallmarks of rhabdomyolysis secondary to upper extremity reperfusion injury and allows for monitoring in vivo upper limb function using clinically relevant electrodiagnostic and kinematic metrics. In addition to inducing severe metabolic derangements, our forelimb PRS provided insights on gross motor and electrophysiological alterations upper extremity reperfusion injury. We identify gait coordination parameters such as stride frequency and forelimb-hindlimb coordination index and electrophysiological metrics including compound muscle action potential amplitude as objective, non-invasive outcome measures for limb function assessment in small animal models of extremity PRS. This comprehensive, validated functional model can serve as an invaluable tool to evaluate therapeutics or preconditioning regimens to attenuate PRS and mitigate resulting neuromuscular dysfunction.
Neural diversity is key to collective artificial learning

Published: January 2025

Many of the world’s most pressing issues, such as climate change and global peace, require complex collective problem-solving skills. Recent studies indicate that diversity in individuals’ behaviors is key to developing such skills and increasing collective performance. Yet behavioral diversity in collective artificial learning is understudied, with today’s machine learning paradigms commonly favoring homogeneous agent strategies over heterogeneous ones, mainly due to computational considerations. In this work, we employ novel diversity measurement and control paradigms to study the impact of behavioral heterogeneity in several facets of collective artificial learning. Through experiments in team play and other cooperative tasks, we show the emergence of unbiased behavioral roles that improve team outcomes; how neural diversity synergizes with morphological diversity; how diverse agents are more effective at finding cooperative solutions in sparse reward settings; and how behaviorally heterogeneous teams learn and retain latent skills to overcome repeated disruptions. Overall, our results indicate that, by controlling diversity, we can obtain non-trivial benefits over homogeneous training paradigms, demonstrating that diversity is a fundamental component of collective artificial learning, an insight thus far overlooked.
Beyond inorganic carbon: Soil organic carbon as key pathway for carbon sequestration in Enhanced Weathering

Published: January 2025

Enhanced weathering captures CO2 via two pathways: Carbonate formation and leaching of weathering products. Here, we look beyond those two pathways, identifying other CO2 sinks and sources. While processes such as clay formation or organic matter decomposition reduce the efficiency of enhanced weathering, organic matter stabilisation could contribute to C storage. In a 15 month mesocosm experiment including two different types of silicates (basalt and steel slag) inorganic CO2 sequestration indeed remained negligible (below 0.1 t CO2/ha) due to clay formation. Also organic matter decomposition increased in silicate amended treatments (basalt +0.9 and slag +1.1 t CO2/ha released), further lowering the CO2 removal efficiency of enhanced weathering. Other organic C pathways could however contribute substantially to C storage. Aggregate formation and the storage of C within them was promoted in silicate amended treatments (basalt +106 and slag +73 % organic C stored in aggregates >250μm). Next to that, the association of organic C to minerals was determined another possible organic C sink. These results underline the urge for reliable ways to quantify CO2 removal not only including inorganic but also organic carbon dynamics.

Published: January 2025

Background: Missed care causes irreversible complications for infants in neonatal intensive care units. On the other hand, time-consuming actions such as record can effect the type and quality of care. Although no study was found on the effect of manual and electronic record of nurses on missed care, the present study was conducted to compare the effect of manual or electronic recording methods on the missed care in neonatal intensive care nurses.
Methods: A descriptive comparative multicenter study was conducted from September 2022 to February 2023 by census of 151 nurses in the neonatal intensive care units. Tubbs-cooley missed care questionnaire was used for data collecting. Data was analyzed by SPSS software version 26.
Results: There was no significant difference in the mean difference between the electronic and manual records (30 intensive care) in the majority of cares item(p<0.05). Only in three cares, "observing the correct principles of drug administration (8 rights)", "reviewing high-risk drugs according to the protocol" and "adjusting oxygen based on the saturation level according to the protocol or order", a statistically significant difference was observed between electronic and manual record. The mean scores for electronic records were lower than manual records and close to one score (complete care).
Conclusion: In neonatal intensive care unit, because of high sensitivity of caring, nurses should complete the types and details of cares and methods of records have no significant effect on missed care. It seems that electronic record provides more opportunity for ideal care and may play a role in decreasing missed care.
Designing small molecules that target a cryptic RNA binding site via base displacement
Authors: Batey Robert , Olenginski Lukasz , Wierzba Aleksandra , Laursen Shawn
Published: January 2025

Most RNA-binding small molecules have limited solubility, weak affinity, and/or lack of specificity, restricting the medicinal chemistry often required for lead compound discovery. We reasoned that conjugation of these unfavorable ligands to a suitable “host” molecule can solubilize the “guest” and deliver it site-specifically to an RNA of interest to resolve these issues. Using this framework, we designed a small molecule library that was hosted by cobalamin (Cbl) to interact with the Cbl riboswitch through a common base displacement mechanism. Combining in vitro binding, cell-based assays, chemoinformatic modeling, and structure-based design, we unmasked a cryptic binding site within the riboswitch that was exploited to discover compounds that have affinity exceeding the native ligand, antagonize riboswitch function, or bear no resemblance to Cbl. These data demonstrate how a privileged biphenyl-like scaffold effectively targets RNA by optimizing π-stacking interactions within the binding pocket.

Volumetric super-resolution (SR) live imaging at high-speed for long-time remains challenging, especially for fluorescent thick specimens. In this work, we develop Lattice light sheet Activation Structured Illumination Microscopy (LA-SIM), which integrates the unique advantages of superior optical sectioning and low photo-toxicity offered by light sheet configuration with full-version SR-SIM in both linear and nonlinear schemes together, by means of reversibly photo-switchable fluorescent protein (rsFP). Moreover, LA-SIM allows implementing rationalized deep-learning (rDL) denoising in a self-supervised manner, enabling the production of high-quality three-dimensional (3D) SR images at limited SNR levels, while achieving bona fide optical resolution improvement beyond 2-fold relative to diffraction-limit in both lateral and axial dimensions. We utilize the high-quality rDL LA-SIM data to train a large-scale transformer model --- SRFormer that can overcome the inferior properties of rsFPs and enable multi-color long-term volumetric SR imaging. We demonstrate that SRFormer LA-SIM can shed new light on subcellular dynamics from single-cell to multi-cellular specimens.

One preferred lead-free ferroelectric, (K,Na)NbO3 (KNN), is gifted with the prominent features of environmentally benign and excellent piezoelectricity in both its ceramic and film forms, but it suffers from poor ferroelectricity. Albeit intensive researches have demonstrated the efficiency of Mn-doping in improving the electrical properties of KNN, the occupancy of Mn (A- or B-site) remains elusive. Here, we have formed Mn-atomic-layered antiphase boundaries in KNN-based films, and observed that Mn occupied the A-site position. The Mn-inlaid antiphase boundary has been shown to induce stable ferroelectricity with robust polarization (2Pr ~ 72.5 µC/cm2) in KNN-based films. This stability is retained across a wide range of test frequencies, from as low as 20 Hz, and up to 10 kHz, which is of great significance in KNN system. The atomically resolved STEM images reveal that densely arranged antiphase boundaries are formed and grown along three crystal axes by half unit cell lattice mismatch throughout the entire thickness of KNN-based films. These boundaries are Mn-atomic-enriched at a nanoscale width of a single unit cell, which could equilibrate the interfacial charges and clamp the vertical interfacial strain, resulting in the highly squared hysteresis loops and high Curie temperature of ~ 400 ℃ in our films. Meanwhile, these films also exhibit a high dielectric constant of 1200 and optical transmittance of ~ 75%. Our results may provide a new paradigm for designing new type of high-performance KNN-based lead-free ferroelectric films, unleashing their application potential for expelling lead-containing counterparts.

Published: January 2025

Streptococcus pneumoniae is a major cause of pneumonia, meningitis and other invasive diseases resulting in high mortality and morbidity among children. In recent years, the issue of drug resistance in Streptococcus pneumoniae has become increasingly prominent, posing challenges to clinical treatment. Besides, the typing of Streptococcus pneumoniae is important information for evaluating the value of pneumococcal vaccines and developing immunization strategies. A total of 105 Streptococcus pneumoniae isolates were collected from ten cities in Sichuan Province in 2023. The leading serotypes were 19F (34.29%), 19A (10.48%), 3 (7.62%) and 6E (7.62%), with CC271 and GPSC1 being the predominant types. The overall coverage rates of 7-, 10-, 13-valent pneumococcal conjugate vaccines (PCV7, PCV10, PCV13) and 23-valent pneumococcal polysaccharide vaccine (PPV23) were 45.71%, 45.71%, 64.78% and 69.52%, respectively. The antimicrobial susceptibility test of Streptococcus pneumoniae showed that most strains were resistant to erythromycin (ERY), clindamycin (CLI), tetracycline (TCY), and trimethoprim/sulfamethoxazole (SXT), with a multidrug resistance rate of 85.71%, and CLI/EY/TCY was the main resistance mode. The resistance rate of strains isolated from the children's group and the elderly group to SXT was higher than that of the adult group, and the difference was statistically significant (χ 2 = 12.143, p = 0.002). In summary, continuous monitoring of the antibiotic resistance of Streptococcus pneumoniae is crucial for controlling and preventing the development of antibiotic resistance in pneumococcal bacteria. Our research is beneficial for understanding the type distribution of Streptococcus pneumoniae in Sichuan province and guiding the rational use of drugs and adjustment of vaccination strategies in clinical practice.

Published: January 2025

Background: The current study aimed to investigate the factor structure, reliability, and validity of the Arabic adaptation of InCharge's Financial Distress/Financial Well-Being Scale, along with a new single-item measure to assess financial stress (i.e., the Single-Item Financial Stress scale, SIFiS) among Lebanese adults.
Methods: In this cross-sectional study, 403 participants completed an Arabic-translated IFDFW via an online survey. Confirmatory Factor Analysis was used to validate the scale.
Results: A one-factor structure was supported by the analysis. Internal reliability was excellent, with very high omega and alpha coefficients for the IFDFW scale (ω = 0.95, α = 0.95). A significantly lower mean IFDFW score was found in males compared to females. On the hand, no significant differences were found between males and females on the SIFiS scores. Greater financial burden was significantly associated with higher levels of depression, anxiety, and stress.
Conclusion: The findings confirm that the Arabic versions of the IFDFW scale and the SIFiS are valid and reliable. Their use is therefore recommended in various settings among Arabic-speaking adults. These simple and straightforward measurement tools may improve cross-cultural studies on financial well-being.

Published: January 2025

Alzheimer's disease (AD) is the utmost age-linked neuro-degenerative conditions, marked via gradual deterioration of cognitive abilities and continues to be a significant worldwide health issue. Etiology of AD is linked to neurobehavioral variations, deposition of Aβ, p-Tau, activations of GSK-3β, and fluctuations in cyclic nucleotides including cAMP & cGMP. As per evidence, PDE-5 inhibitors are able to boost cAMP & cGMP levels and other etiological hallmarks, which could be a novel AD cure. The main objective of present study was to examine therapeutic potential of Avanafil in a rat model of AD induced by administering 60mg/kg of D-galactose (D-galac) and 10mg/kg of Aluminium chloride (AlCl3) for a period of 42 days. Following this, 28 days of therapy with two different doses of Avanafil (3mg/kg and 6mg/kg) was given. Towards end of treatment, locomotor activity & Morris water maze were performed. Rats were then euthanized and hippocampus was isolated for biochemical parameters & histological investigation. Results revealed that both neurobehavioral parameters exhibits significant difference in treatment group as compared to toxic group. Alterations in level of AchE, Aβ (1–42), GSK-3β, p-Tau, TNF-α, IL-1β, & IL-6, cAMP, cGMP & BDNF, and oxidative stress were significantly reversed towards normal level in the treatment group when compared to toxic rats. Histopathological changes by H&E staining showed significant difference in treatment vs. toxic rats. The current investigation suggested that Avanafil improves memory by improving cAMP and cGMP pathways, implying that it may have therapeutic prospective in cognitive deficiencies linked with Alzheimer's disease.
Evaluating Multimodal Large Language Models for Implicit Advertising Reasoning
Authors: Sun Haozhi , Yuan Heng
Published: January 2025

In this paper, we present a novel method for implicit reasoning in advertising, focusing on the use of a multimodal large language model integrated with a specialized prompt engineering approach. Advertising often involves implicit reasoning, where messages are conveyed indirectly through a combination of text, images, and emotions. This makes it challenging for traditional models to capture the subtle nuances involved. To address this, we propose an innovative multi-round prompt design that enables the model to refine its reasoning process iteratively, thus improving its ability to decode implicit intentions in advertisements. Our method leverages GPT-4 as the core reasoning engine, and the prompts are designed to guide the model through multiple reasoning phases, ensuring that it effectively incorporates both textual and visual cues. We collect a custom dataset of advertising content to train and evaluate our approach, and our results demonstrate significant improvements in reasoning accuracy compared to baseline models. We also propose novel evaluation metrics, which go beyond traditional accuracy and incorporate human-like reasoning assessments. Experimental results and human evaluations show that our method outperforms existing models, both in terms of reasoning depth and interpretability, making it a promising solution for understanding complex advertising content.

Antimicrobial resistance (AMR) continues to rise, making a growing number of infectious diseases difficult to cure. Millions of people worldwide die from infections with medication resistance. According to the World Health Organization (WHO), a resistant variant has a 64% higher chance of killing an infected victim than a non-resistant variant. As a result, scientists continue to focus research attention on finding novel chemotypes that could have different modes of action. Combination therapy has the potential to overcome AMR since the therapeutic components work together to suppress the etiological microorganism. In the current study, we investigated the antibacterial properties of crude alkaloidal extract of Phyllanthus fraternus (AEPF) using high-throughput spot culture growth inhibition (HT-SPOTi) assay. We performed time-kill kinetic assays to assess the interactions between the crude alkaloids and test microbial strains. The ability of the crude alkaloids to alter the antimicrobial action of standard tetracycline was evaluated by modulation study. Our findings indicate that P. fraternus alkaloids effectively suppress majority of clinically significant pathogenic strains in vitro. Bactericidal effect was shown by time-kill kinetics against S. aureus, E. coli (ATCC 43888), and E. coli (ATCC 10455). Tetracycline was successfully potentiated against Shigella sp. by the alkaloidal extract. The crude alkaloid extract of P. fraternus included two known alkaloids, epibubbialine and ent-norsecurinine, according to LC-ESI-MS analysis. Taken together, the antibiotic activity of P. fraternus is primarily due to its alkaloids and that the potential exists to develop isolated alkaloids as drug candidates for use in combination therapies against antimicrobial resistance.
Innovative Approaches to Ensuring Cybersecurity and Public Safety: The Socio-Economic Dimension

Published: January 2025

This study is devoted to the analysis of socio-economic aspects of the development of cybercrime and the involvement of society, both as victims and direct initiators, in this activity. The paper examines the impact of socio-economic development indicators, in particular gross national income, spending and remittances, literacy and unemployment, on the dynamics of cybercrime worldwide, and analyses trends in public awareness and involvement in criminal activity in the digital space. The methodological tools of the study are the methods of correlation and canonical analysis, implemented in the Statistica 12 software. The analysis of the relationship between the socio-economic conditions of society and cybercrime-related behaviour established a dual impact of these factors on vulnerability to cybercrime and participation in criminal activity as a way of income generation. On the one hand, socio-economic disparities, in particular income inequality and unemployment, contribute to the increasing vulnerability of society to cybercrime. On the other hand, a high level of poverty among the population motivates a certain part of it to participate in cybercriminal activities. The results of the study indicate that socio-economic inequality and unemployment play a critical role in managing cybercrime risks. A higher level of economic development and social security is accompanied by greater resilience to cyberthreats, while a high level of unemployment and significant economic inequality increase the vulnerability of society to such risks. The findings also revealed that the socio-economic development of the country largely depends on the level of its cybercrime. This highlights the need to integrate cybersecurity measures into national economic development strategies. The practical significance of the obtained results lies in the application of a comprehensive approach to understanding cybercrime, which considers both victimization and active participation of society in this activity. This study can serve as a basis for the development of targeted measures to prevent cybercrime and increase the resilience of society to cyberthreats. The findings highlight the importance of integrating economic and social components in the development of effective cybersecurity strategies, which will contribute to minimizing the risks associated with the use of digital space and strengthening the socio-economic stability of the country.

Mariakrite is a new mineral in the hydrotalcite supergroup, and a member of a novel family of layered double hydroxides, or LDH. It is the first reported LDH with dithioferrate, [Fe3+S2]− in the role of an interlayer anion, the first cementitious layered Ca-aluminate (AFm phase) intercalated with sulfide, and the first sulfide-intercalated LDH with completely solved crystal structure. Mariakrite was discovered in late hydrothermal assemblages confined to pyrometamorphic lithologies of the Hatrurim Formation, in the Negev Desert on the Israeli side of the Dead Sea. The mineral forms saber-like crystals up to 2 mm long, 0.1 mm wide and 0.5 to 2 μm thick, residing in millimeter-sized cavities within larnite-jasmundite-brownmillerite rock. Associated minerals are katoite, portlandite, kuzelite and hydrocalumite. Mariakrite has a purple-brown color with semimetallic luster; in transmitted light, it is transparent green-grey. The crystals are flexible and elastic. Mohs hardness is 3–3.5. Calculated density is 2.005 g cm−3. In reflected light, the mineral exhibits extreme pleochroism, from grey to red-purple. Anisotropy is very strong.

Published: January 2025

Nowadays, with the rapid breakthroughs in software and AI technology, the growing use of AI among university students has sparked considerable debate. In this context, the present research seeks to understand the impact of AI-assisted writing tools on students' perceptions of fairness, academic integrity, and their learning outcomes. An exploratory sequential design was used in this study, beginning with two focus groups to gather qualitative insights that informed the development of a 22-item survey. The survey was then administered to 107 students from the English departments at three institutions of Mohamed V University: FLSH, FSE, and ENS. The results indicate that AI use significantly affects students’ perceptions of fair assessment, with many viewing it as a tool that enhances work quality and academic grades. However, the use of AI is also associated with reduced motivation, lower willingness to invest effort, and diminished self-confidence. To address these challenges, participants suggested alternative assessment methods, including oral exams, tasks that emphasize critical thinking and creativity, and group work. By Analyzing these findings through the lens of Equity Theory and in light of existing research, this study offers insights into the evolving dynamics of fairness and academic integrity in the era of AI. It also offers recommendations for adapting assessment practices to maintain equity and integrity in higher education.

Companies need to follow a continual strategy of knowledge improvement and innovation to maintain their competitive advantage in the face of rapid technological advances and global competition. This method, known as intellectual capital (IC), aids businesses in keeping their edge in the market. Managers should pay attention to IC because of this reason. This study looked at how IC affected the bottom line of a company listed on the ISE in Iraq. The study studied data from a subset of the ISE-listed manufacturers throughout the span of ten years, from 2010 to 2019. Multivariate regression, as well as the F-Limer, Chow, and Hausman tests, were used to examine the data. It was shown that IC improved both ROA and ROE. The results also showed that the capital added value coefficient (COAV) positively impacted ROA but had no discernible impact on ROE. Moreover, ROA and ROE were found to be positively impacted by structural capital's coefficient of added value COAV. And while it had little impact on ROA, the added value coefficient (AVC) of human capital (HC) had a positive and large impact on ROE.

In this study, the relationship between happiness and organizational commitment in workers in the fishing sector of the City of Chimbote was investigated. A correlational quantitative approach and a non-experimental cross-sectional research design were used to determine the association between these two con-structs and to verify if there is a significant relationship between them. To collect data, a survey was applied to a sample of 342 workers in the fishing sector. Two measurement instruments were used to assess happi-ness and organizational commitment. The participants provided information about their level of subjective happiness and their degree of commitment to the organization in which they worked. The results revealed a significant positive correlation between happiness and organizational commitment. These findings support the idea that happiness in the workplace can have a positive impact on employee engagement with the or-ganization. These results are consistent with previous research that has also found a positive relationship between happiness and organizational commitment. This suggests that promoting happiness at work can be beneficial in fostering employee commitment to the organization. However, it is important to note that this study has its limitations. It focused on a specific industry and a particular geographic location, so the results may not be generalizable to other industries or locations. In addition, a self-report measure of happiness was used, which may be subject to bias and limitations. In future research, it would be useful to explore these relationships in different work contexts and consider using more objective measures or various sources to assess happiness. This would help to obtain a more complete and generalizable understanding of how happi-ness at work is related to organizational commitment.

Nowadays, rivalry can be observed not just between businesses, but also between universities. Higher edu-cation institutions have been under increasing pressure from external factors including labor and education market rivalry to improve the quality of their programs by reevaluating their organizational structures and management practices. This study set out to determine how performance-based budgeting would affect the quality of Iraq's postsecondary institutions. The statistical subjects of this study are those involved in per-formance-based budgeting in Iraqi universities, including the deans of the faculty and deputy deans, the director of the accounting department, and the financial and accounting staff. Morgan's table suggests a minimum sample size of n=246. This is because 3519 individuals were sampled from the population of non-professional private higher education institutions in Iraq. A total of 198 completed surveys were submitted. The collected data from the questionnaire was analyzed using a structured equation model. The results indi-cated that performance-based budgeting benefited greatly from considering organizational commitment and rewards mechanisms. The results, however, showed that the competence of managers played no impact in the introduction of performance-based budgeting in Iraq's higher education sector. However, the results showed that performance-based budgeting had no effect on the quality of higher education in Iraq, and nei-ther did the competency nor the organizational commitment of managers in these institutions, nor did re-ward schemes.

The iron-steel industry, which has a large part of its energy consumption, strives to stay at the targeted level in the competition race and to hold on in the field in which it operates. For this purpose, production capacity turned to different energy saving methods due to the effort to reach the relevant standards and high quality low cost strategies. But, energy prices are constantly variable and energy costs are high. In this study, the Blast Furnace Top Pressure Turbine system (TRT), which is one of the important energy saving methods of the iron and steel industry, was examined. Considering the importance of the TRT system, operating condi-tions, operating parameters, and factors affecting energy recovery, the effect of various operating parameters on the operation of the TRT system was evaluated. Considering the annual operating time of 8000 hours, the annual production amount is 42400000 kWh, the value in terms of tons of oil equivalent is 3640 toe, the investment cost of the plant in 2018 is $400000 and the annual savings amount is $2755900. The amount of carbon emission reduction due to this production amount was calculated as 10888 kgCO2/h on average, and this amount of carbon emission was prevented every year with the commissioning of the facility. When the cost and energy calculations related to the system are examined, the payback period of the project is calcu-lated as approximately 0.15 years. The obtained data showed that the TRT system is a suitable method for energy saving in the iron and steel industry.

Published: January 2025

Internal control is a critical strategy employed by organizations to enhance efficiency and operational effec-tiveness. Accounting information systems (AIS) also serve as valuable tools for acquiring necessary infor-mation to evaluate the performance of both managers and employees. This study examines the impact of internal control on employees' performance in small and medium-sized enterprises (SMEs) in Iraq, with a particular focus on the moderating role of accounting information systems (AIS). Questionnaires were dis-tributed among SMEs in Iraq, and data from 198 responses were analyzed using structural equation model-ing (SEM). The findings indicate that internal control has a positive and significant influence on employees' performance in Iraqi SMEs. Furthermore, the utilization of information systems contributes to improved employee performance. However, the study did not find evidence of AIS moderating the relationship be-tween internal control and employees' performance. Based on these findings, it can be concluded that in the economic context of Iraq, particularly within SMEs, internal control plays a crucial role in enhancing effi-ciency and improving employees' performance. Additionally, information systems have the potential to make a substantial impact in this domain. Nevertheless, it is imperative for these systems to be regularly updated and upgraded to effectively influence all departments and components within an organization. This research contributes to the understanding of internal control and information systems in SMEs in Iraq, which can aid similar organizations in developing economies.

Published: January 2025

Many applications in lifestyle need to use some kinds of antenna especially in communication field. One of these antennas that is used in this field of communication is called dielectric resonator antenna (DRA). In this review, we will compare different kinds of DRA antennas, for example, cylindrical and rectangular DRA antennas, based on their S-parameters, gain, directivity, bandwidth, and voltage standing wave ratio (VSWR). After discovering the studies about characteristics of these antennas according, the technology of gain, bandwidth enhancements used in the literature will be explained in detail, such as using a high-dielectric-constant material, adjusting its resonant frequency, property of lensing of MTM cells. In practical experiments, the software CST (Computer Simulation Technology) is used for this purpose, to evaluate the above-mentioned parameters of DRA antennas. The advantages of DRA antennas are high radiation effi-ciency, small size, low profile, and lightweight after changing some elements or structure of DRA antenna, which makes the antenna have more attenuation. To enhance the S-parameters and gain magnitude, the suit-able design of DRA depends on the geometrical and material characteristics used for this purpose. This also enables us to achieve acceptable results with high efficiency. Therefore, the simulation of the antenna must consider beside these properties and characteristics, the effects of surface plasmon waves on the properties of DRA antenna. Adding layers of photonic crystal to the DRA antenna enhances the results and leads to higher gain.
Felmérő szakirodalmi áttekintés a szülés körüli anyai tapasztalatok és a társadalmi-gazdasági tényezők közötti kapcsolatról az OECD-országokban
Authors: Udvari Orsolya
Published: January 2025

A társadalmi egyenlőtlenségek jelenléte az egészségügyi ellátásban széles körben ismert és kutatott jelenség. Ezen belül is a szülés körüli ellátást érintő egyenlőtlenségi kérdések egy kevésbé feltárt területnek számítanak. A szülés körüli tapasztalatok számos tényezőtől függenek, beleértve az életkort, a társadalmi helyzetet, az etnikumot, a szülés módját és a szülészeti bánásmódot. Az alacsony társadalmi-gazdasági helyzetű nők különösen kitettek lehetnek a negatív szülésélményeknek, amelyeknek rövid és hosszú távú hatásai mind az anyára, mind pedig társadalmi környezetére kimutathatók. Jelen tanulmány a felmérő szakirodalmi áttekintés módszerével az anyai társadalmi-gazdasági helyzet és a szülés körüli tapasztalatok összefüggése mentén térképezi fel az elmúlt tíz év OECD-országokra vonatkozó nemzetközi szakirodalmát. A tanulmány 18 cikk áttekintésének eredményeként megállapítja, hogy a szocioökonómiai háttér figyelembevétele a szülés körüli tapasztalatok alakulásának és hatásainak megértésében döntő szerepet játszik.
