Authors: Shelepina Ellina
Published: January 2025

The article discusses the relationship between fatigue and the peculiarities of the mental state of ATS employees, including discussing which types of moods are dominant among ATS employees with different values of fatigue. The study involved 470 employees of the Department of Internal Affairs who underwent initial training and advanced training at the St. Petersburg University of the Ministry of Internal Affairs of Russia (312 male employees, 158 female employees with service experience from 1 year to 15 years). The following psychodiagnostic techniques were used: the questionnaire "Determination of the dominant state" (L. V. Kulikov), the questionnaire "Subjective assessment of the level of fatigue of the individual" (S. V. Dukhnovsky, E. K. Shelepina). During the correlation analysis, significant relationships were established between the fatigue indicator (according to the method of "Subjective assessment of the level of fatigue of the individual") and such parameters of the dominant mental state as "active (passive) attitude to the situation", "cheerfulness (despondency)", "high (low) tone", "looseness (tension)", as well as "life satisfaction" according to the method of "Determining the dominant state". During the comparative analysis, significant differences in the characteristics of the mental state of police officers with different values of fatigue were established. Among other things, it was found that for employees of the Department of Internal Affairs with low fatigue values, the dominant types of mood will be "inspired" and "prosperous"; with moderate values - "active"; and with high values - "sad (melancholic)".

Foreign and domestic studies of the psychological characteristics of extreme conditions of service
Authors: Zhuk Kristina
Published: January 2025

The current reality dictates the conditions for prioritization. Military conflicts in the world increase the level of tension in society. In such an environment, increased responsibility is assigned to employees who perform official tasks in extreme conditions. Now many people understand that the methodology of military affairs has changed dramatically, an employee may not be a participant in the actual fighting, but the expectation itself can harm human health. The problem is that extreme conditions in every person's life are already becoming an element of life activity. However, not everyone has the skills to recognize personality changes due to the development of negative situations. Purpose: to analyze the experience of various studies, the results of which contribute to the definition and identification of psychological characteristics that manifest themselves in extreme conditions. Compare studies from different years in this field. Methods: the study of scientific publications. Conclusions: after analyzing studies from different countries, it can be concluded that despite ethnic, linguistic, and value differences, extreme conditions have an identical negative effect on a person. However, a number of authors say that the more prepared an employee is (able to recognize emotions, use various techniques, have a sufficient level of neuropsychiatric stability, etc.), the less they are exposed to extreme conditions.

This paper examines the impact of playing tennis on the visual system, providing an in-depth analysis of physiological, adaptive, and risk-related aspects associated with the sport. The dynamic nature of tennis necessitates intensive visual engagement to track a fast-moving ball, thereby enhancing dynamic vision, depth perception, and visuomotor coordination. On the other hand, the sport also poses risks such as eye strain and mechanical injuries, including corneal and retinal damage.
The study underscores the importance of peripheral vision in the game and the need for the visual system to adapt to varying lighting conditions. The authors highlight the benefits of implementing vision exercises and protective measures, such as sunglasses and contact lenses. The significance of preventive measures, regular eye check-ups, and education for players, coaches, and parents is also emphasized. Although demanding, tennis offers opportunities to improve visual functions, contributing to athletic development and visual health.

Published: January 2025

Introduction and Objective: N-Acetylglutamate Synthetase Deficiency (NAGSD) is a rare urea cycle disorder, primarily caused by autosomal recessive genetic mutations. Most affected individuals are homozygous for the disease-causing allele. The aim of this publication is to discuss various aspects of N-acetylglutamate synthetase deficiency based on the latest literature.Review Methods: The PubMed database was searched to find scientific articles in which the terms "N-acetylglutamate synthetase," "NAGS deficiency," or "N-acetylglutamate synthetase deficiency" appear in the title, abstract, or keywords.Brief Description of the State of Knowledge:  Symptoms of NAGSD typically appear in the neonatal period. The NAGS enzyme is essential for catalyzing the synthesis of N-acetylglutamate, an allosteric activator of carbamoylphosphate synthetase 1 (CPS1), crucial for the urea cycle. Key biochemical markers include elevated ammonia, glutamine, and alanine; decreased citrulline; and respiratory alkalosis. Hyperammonemia is the main clinical feature, manifesting as nausea, vomiting, cognitive impairment, seizures, and, in severe cases, coma or death. Genetic testing remains the cornerstone of diagnosis, enabling identification of specific mutations. Treatment involves carbamylglutamate, an NAG analog that activates CPS1.Summary:  Expanding research aims to explore novel treatments in NAGSD, dietary strategies, and the safety of current therapies during pregnancy.

Published: January 2025

The study examines the long-term (2011-2023) analysis of thunderstorm and lightning activities and their impacts on local meteorology and air pollutants over Bengaluru. The diurnal thunderstorm events occur mainly in the late evening hours (1900–2100 IST) and on monthly maximum in May while minimum in January. Annually, Bengaluru experiences an average of 41 thunderstorms and 157 lightning strikes, both of which have shown a statistically significant upward trend at a 95% confidence level. The rate of increase is 3.41% per year for thunderstorms and 3.3% per year for lightning events. Local temperatures coupled with abundant moisture supply from the southwest/northeast monsoon creates a favourable condition for the initiation of thunderstorms over the region. This study also focused on the trend analysis of meteorological parameters and atmospheric compositions, a rising trend were found in rainfall (1.44 mm year–1), RH (0.74% year–1) & pressure (0.03 hPa year–1) whereas a slight declining trends in temperature (0.06 0C year-1) & wind speed (-0.02 ms-1 year–1). As the availability of heat and humidity are two main prerequisites for the occurrence of thunderstorm and hence the probability of severe thunderstorms may increase in future. The AOD, NO2 & O3 showed a significant increasing trend while no trend for SO2. The Pearson correlations showed the AOD, NO2 & SO2 concentrations are significant negatively correlated with wind speed but positively correlated with atmospheric pressure. A further study indicated a significant impact of thunderstorm on the air pollutants has also been quantified and it was observed that PM2.5 concentration gradually decreases after the commencement of thunderstorm while quick increase response (less than 1 hour) was observed in O3 and delay response (after 2:30 hours) in NO2 which may linked to lightning activities. The results reveal that thunderstorms can affect both the local meteorology as well as atmospheric pollutants and vice-versa from regional to global.

Authors: Vijay Niyathi , Sarasamma Jaya Divakaran
Published: January 2025

The quality air in the indoor environment significantly impacts anthropological health and well-being. Suboptimal environmental air quality can lead to respiratory and other diseases among students worldwide. The objective of this study is to scientifically evaluate and summarize the available data on Indoor Air Quality in Indian school settings, based on a review of relevant research papers. From the 172 articles analysed, there are only 36 articles related to the Indian perspectives on indoor air quality. In an Indian scenario, thermal comfort inside a school classroom is directly proportional to the natural ventilation. The review of the available research articles illustrates that occupants all over India are adapted to a temperature range of 17 - 33.70 C, with a difference in climate. Case studies on indoor air quality in schools have consistently identified eight key pollutants of concern: Carbon monoxide (CO), Particulate matter (PM), Nitrogen dioxide (NO2), Sulphur dioxide (SO2), Ozone (O3), Volatile Organic Compounds (VOCs), and Bioaerosols. Climate change may worsen indoor air quality and cause new problems as the frequency of adverse outdoor conditions changes. Further research is essential to study indoor air pollution in schools and its associated health impacts, utilizing standardized protocols and methodologies to ensure comparable and reliable data

Published: January 2025

Aims/Background Research evidence has demonstrated a significant association between hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF), but the causality and pattern of this link remain unexplored. Therefore, this study investigated the causal relationship between HCM and AF using a two-sample and bidirectional Mendelian randomization (MR) approach. Additionally, this assessed the role of cardiovascular proteins (CPs) associated with cardiovascular diseases between HCM and AF by applying a two-step MR analysis.

Methods Data for HCM, AF, and 90 CPs were obtained from the Finn Gen and IEU Open GWAS Project databases. MR-Egger, inverse variance weighting (IVW), weighted median estimator (WME), weighted mode, and simple mode were used to estimate causal inferences. Furthermore, Cochran’s Q test, MR-Egger’s intercept terms, and Leave-one-out methods determined the heterogeneity, horizontal pleiotropy, and sensitivity. Additionally, mediation effects were used to assess the role of CPs in the relationship between HCM and AF.

Results Two-sample and bidirectional MR analysis revealed HCM as a risk factor for AF (odds ratio (OR) = 1.008, 95% confidence interval (CI): 1.001–1.016, p = 0.029) and AF was found to increase the risk of developing HCM (OR = 1.145, 95% CI: 0.963–1.361, p = 0.126). Moreover, Two-step MR analyses indicated that 5 CPs were causally associated with HCM; 12 CPs with AF and 1 CP (Melusin) with both HCM and AF. Additionally, Melusin was observed as a protective factor for both HCM and AF and may serve as a mediator variable for these two conditions (mediation effect 0.0004, mediation ratio 5.5178%, 95% CI: 5.4624–5.5731).

Conclusion HCM may increase the risk of developing AF, with Melusin serving as a mediator for this risk.

Published: January 2025

Abstract: The theoretical underpinnings of police and penal abolition can provide important epistemological guidance to social science researchers. A review of the conceptual frames of abolition and the social science theories underlying it provides a basis for an abolitionist epistemology that incorporates insights from queer theory, critical race theory, feminism, historical materialism, and postcolonial theory. An exposition of existing studies that conform to these theoretical frameworks shows this approach’s value.
3D reconstruction of a highly reflective surface based on multi-view fusion and point cloud fitting with a structured light field
Authors: Feng Wei , Liu Qianqian , Wang Henghui , Xu Jiangtao , Wang Xuanze
Published: January 2025

In this paper, a three-dimensional (3D) reconstruction method based on multi-view fusion and point cloud fitting is proposed to accurately reconstruct the highly reflective surface, which can effectively restore the highlight regions with only a single shot. A multi-view image fusion method based on the characteristics of microlens array cameras is used to remove unsaturated highlights. A new adaptive method, to our knowledge, based on binary images is designed to quickly extract the highlight regions. Then, what we believe to be a novel B-spline point cloud repair algorithm is proposed to construct geometric features for the highlight regions, and the weighted least squares plane fitting method based on priority is utilized to remove the saturated highlight point by point. More importantly, the 3D reconstruction system based on a structured light field is set up independently to verify the feasibility and effectiveness of the proposed method. The experimental results show that the proposed method can effectively achieve 3D reconstruction with large reflectivity changes and large highlight areas, and its repaired rate can reach 98.44%. Consequently, the proposed method can fully restore all highlight regions and can uniformly, accurately, and smoothly recover different highly reflective surfaces while avoiding hardware complexity.

Authors: Liu Chun-Xiao , Xing Shu-dong , Wang Zi-Hao , Li Ke-Yao , Sun Wang , Zhou Yu-Cheng
Published: January 2025

In this work, we report on the fabrication and Faraday rotating properties of the ridge waveguide in magneto-optical glass. The planar and ridge waveguides are formed using 0.4MeVHe+-ion implantation with a fluence of 6×1016ion/cm2 and 2.0×104rpm diamond blade dicing with a speed of 0.2 mm/s. The refractive index distribution and dark-mode spectrum are obtained by the RCM and prism-coupling system, respectively. Zeiss and Nikon microscopes are used to capture the micro-images of the planar and ridge waveguides, respectively. After annealing at 260°C for 1 h, the near-field light intensity distributions of the planar and ridge waveguides are measured by the end-face coupling method. Faraday rotation of the bulk and ridge waveguides is measured and analyzed based on the magneto-optical effect measurement system. Although there is a slight reduction in the Verdet constant of the waveguide compared with that of pure magneto-optical glass, the Faraday effect is well preserved in the ridge structure. It has potential for applications in magneto-optical waveguides as integrated optical rotators and isolators.

Published: January 2025

Efficiently coupling free-space light with a large bandwidth to arbitrary positions in on-chip systems is a significant challenge. In this work, we address this issue by utilizing an inverse-designed metasurface as a meta-coupler, replacing conventional grating couplers. Our meta-coupler achieved a maximum coupling efficiency of 90% (). The 1-dB bandwidth spans 138 nm (1450–1588 nm), while the 3-dB bandwidth extends over 300 nm (1425–1725 nm), far exceeding the bandwidth of traditional grating couplers used on thin-film lithium niobate. This meta-coupler demonstrates strong potential for on-chip systems requiring multi-wavelength interactions, such as integrated lasers and amplifiers.
Iterative inversion method for retrieving the optical properties of aerosol under cloud by ground-based scanning lidar
Authors: Zhang Zhisheng , Kuang Zhiqiang , Li Cheng , Deng Qian , Wu Decheng , Liu Dong
Published: January 2025

Low and dense cloud cover is often encountered in daily observing experiments with lidar. In such scenarios, the laser cannot penetrate the clouds and it is not possible to use the clean atmosphere to initially calibrate the calibration heights required for the actual inversion, which can pose a significant challenge to the inversion of aerosols under clouds. This paper proposes an iterative proximal calibration algorithm based on slope method and Fernald's backward integral equation, combined with the inherent observational mode characteristics of the micro infrared lidar (mIRLidar). By conditioning the iterative process, the relative error between the obtained extinction coefficient value and the true value becomes smaller and smaller as the number of iterations increases. According to the inversion results of the actual lidar observation data, it can be tentatively concluded that the use of the proximal calibration iterative algorithm eliminates the limitations of the traditional Fernald height calibration method and improves the accuracy of the under-cloud aerosol inversion.
Usage of time multiplexing super resolution for imaging through scattering medium
Authors: Israeli Elad , Chen Gal , Zalevsky Zeev
Published: January 2025

This paper presents an extension of time multiplexing super-resolution imaging concept to allow imaging through scattering medium. The presented concept includes laser illuminating an object through a diffuser. The technique performs time multiplexing super-resolved imaging through this diffuser while using the unknown speckle pattern the diffuser projects on the imaged object to enhance the resolution at which the object is imaged. Thus, unlike in conventional case where imaging through a diffuser or other scattering medium destroys the imaging resolution, here the speckle pattern the diffuser generates assists in performing super-resolved imaging. Experimental results demonstrate the efficacy of the approach, showing significant improvement in image quality and resolution.
Noise-resistance modified linear programming algorithm for dual-wavelength digital holography
Authors: Li Tuo , Zuo Tianwei , Dong Jun , Zhang Qian
Published: January 2025

The modified linear programming algorithm (MLPA) is an effective solution for dual wavelength digital holography. However, when the thickness of a specimen exceeds one synthetic wavelength, the anti-noise performance of the MLPA method will sharply decrease. To address this issue, we propose a noise-resistance MLPA method (NR-MLPA). The anti-noise performance of the NR-MLPA is much better than MLPA. For example, when the illumination wavelengths are taken as 532 nm and 633 nm, the NR-MPLA method improves the noise resistance of the MLPA method by nearly 4 times. Therefore, NR-MPLA is useful for dual-wavelength digital holography, and a series of numerical simulations and experiment results demonstrates the its effectiveness.

Published: January 2025

The study of high-dimensional solitons will bring great interest and new opportunities for understanding three-dimensional nonlinear physical phenomena and the design of complex nonlinear systems. The development of spatiotemporal mode-locked (STML) lasers has enabled the exploration of high-dimensional soliton dynamics. In this study, an STML laser and a dual-channel real-time measurement system based on dispersion Fourier transform technology were constructed. The real-time spectral evolution of high-dimensional solitons, including dissipative solitons, creeping solitons, and soliton explosions, are observed and studied. The experimental results show the complexity of multimode soliton dynamics. Such as multimode solitons possess the spectral-spatial characteristics that are absent in single-mode solitons, the transformations between steady-state solitons, creeping solitons, and soliton explosions, and the relationship between these transformations and pump energy changes and spatiotemporal saturated absorbers. To the best of our knowledge, this is also the first experimental report on multimode creeping solitons. This work provides insight into understanding complex spatiotemporal soliton dynamics and enriches the exploration of, to our knowledge, novel spatiotemporal dynamics.

Published: January 2025

Fourier ptychographic microscopy (FPM) combines a wide field of view with high resolution, offering a powerful imaging technique. However, positional misalignments introduced during the assembly of the LED array often degrade the image reconstruction quality. In low-resolution sequences, images containing both bright and dark regions separated by an arc-shaped boundary—referred to as transition images—can be utilized to calibrate the positions of the LED array. In this paper, we propose a transition image imaging model that explains the formation of transition images. Using unbiased superimposed images generated at this height as ground truth, we further propose the superimposed image alignment (SIA) algorithm to calibrate the planar offset parameters of the LED array. Multiple simulations and experimental comparisons confirm the accuracy and robustness of the model and the SIA algorithm. In contrast, FPM reconstruction comparison experiments demonstrate the high precision correction capability of the SIA algorithm.
Self-homodyne 2-OTDM for doubling the baud rate in low-energy optical interconnect
Authors: Kurosu Takayuki , Matsumoto Ryosuke , Konoike Ryotaro , Suda Satoshi , Amano Takeru
Published: January 2025

As a low-energy method to increase the data rate of optical links in data centers, we propose self-homodyne Nyquist optical time division multiplexing (OTDM). In Nyquist OTDM, spectrally efficient high-baud rate signals can be generated exceeding the limit of electronic signal processing. However, full integration of OTDM systems has not been reported, mainly because of the complicated signal detection scheme, which involves demultiplexing and clock recovery. In our proposal, the Nyquist pulse train is transmitted to the receiver as a local oscillator (LO) to leverage self-homodyne detection, which allows using large linewidth lasers and a simplified digital signal processing (DSP) algorithm. As the transmitted pulse train serves as an optical clock, demultiplexing and detection of the OTDM signal can be performed without using power-intensive high-bandwidth electronics and DSP. In this method, the LO pulse train needs to enter the coherent detector in exact synchronization with the OTDM signal for detecting the individual tributary correctly. For this purpose, we present a pulse delay control method suitable for photonic integration. A Nyquist pulse train with m carriers enables m-time multiplexing of optical signals. We explain and demonstrate the proposed concept in the case of m = 2, as it is the most feasible implementation. In the O-band where the chromatic dispersion (CD) is negligible, DSP-free operation can be achieved using the QPSK format. At the band edges where CD is non-negligible, it can be compensated by the DSP as in the conventional coherent detection. We verify this numerically and in an experiment involving the transmission of a 64-Gbaud QPSK signal at 1550 nm over a single-mode fiber. In terms of low energy, self-homodyne Nyquist OTDM is advantageous in wavelength division multiplexing (WDM). Taking it into consideration, we perform 4-channel WDM transmission of the 64-Gbaud QPSK signal over a 1-km dispersion shifted fiber without CD compensation. The results demonstrate a data rate of 512 Gb/s with a BER of <1 × 10−10.
Ultra-fast SOP rotation tracking and its enabled feedforward adaptive equalization based on superimposed chirp pilot
Authors: Wang Li , Wang Yue , Wang Jingchuan , He Huan , Lu Liwang , Yu Changyuan , Tang Ming
Published: January 2025

We propose to track state of polarization (SOP) rotation by utilizing chirp pilots processed through fractional Fourier transform (FrFT). Superimposed on dual-polarization data signal, the chirp pilots with different FrFT rotation orders can converge to fractional energy peaks and then be distinguished by combining FrFT with MIMO structure. Consequently, SOP rotation resulting in energy distribution can be estimated by leveraging aggregated peaks in the matched fraction domain. The feasibility of the proposed scheme is verified by an experiment of 480Gb/s DP-16QAM and 600Gb/s DP-32QAM signals over 25 km fiber. Without sacrificing spectrum efficiency, the proposed approach can track SOP rotation up to 5 Mrad/s. To reduce the impact of superimposition, a fractional domain digital match filter (DMF) is proposed to improve the optical signal-to-noise ratio (OSNR) penalty from more than 4.0 dB to 0.9 dB. Furthermore, the SOP rotation estimated prior to MIMO facilitates the implementation of pre-equalization and adaptive step-size of subsequent equalization, thereby achieving feedforward adaptive equalization (FFD-AEQ). Experimental results demonstrate that the FFD-AEQ can cope with SOP rotation up to 4.1 Mrad/s under HD-FEC. Besides, the FFD-AEQ employing pre-equalization has a 39.1% complexity consumption decrease compared to the conventional MIMO.

In this paper, a triple-band dual-polarized frequency selective rasorber (FSR) with multi-band absorption performance is proposed based on the combinatorial lossy structure. The FSR is composed of a top lossy layer, a middle lossy layer and a bottom frequency selective surface (FSS), which are concentrically arranged in a nested configuration. Triple parallel inductor and capacitor (PLC) resonator, integrated circular resonator and composite square and Jerusalem slots provide basically coincident triple passbands for the top lossy layer, middle lossy layer and FSS layer around 8 GHz, 10 GHz and 12 GHz, respectively. The top lossy layer mainly achieves the absorption band below the first transmission window. The middle lossy layer is responsible for the absorption bands between and above the triple transmission windows. Finally, the combinatorial lossy structure successfully integrates the four absorption bands with fractional bandwidths of 74%, 10%, 7% and 30%, maintains the overall triple transmission window, and further expands the reflection restriction band with S11 below -10 dB from 3.4-18.4 GHz (138%). The prototype with 30 × 30 units is assembled to verify the simulated results. Furthermore, the design procedures are given in this paper, which helps in designing multiband FSRs.
Propagation of spatiotemporal necklace-ring solitons in the fractional-order complex Ginzburg-Landau model
Authors: Wang Huiling , He Yingji
Published: January 2025

The overall objective of this work is to study the dynamics of propagation for spatiotemporal necklace-ring solitons (NRSs) with zero and integer angular momentum, as well as the interactions between multiple spatiotemporal NRSs, within the context of the three-dimensional (3D) complex Ginzburg-Landau model that incorporates fractional-order diffraction. An analysis of numerical data is performed on the NRSs, emphasizing the effects of the Lévy index (LI), diffusion parameters, angular momentum, and cubic gain coefficients on the stable propagation of these NRSs. Stable spatiotemporal NRSs were formed, and their stable regions in the system parameter space were preliminarily determined numerically. The LI of fractional-order diffraction significantly affects their stability. The study revealed that the Lévy index and the integer angular momentum influence the minimum radius required for stable propagation of NRSs. Then, the effect of the minimum spacing between multiple spatiotemporal NRSs and the LI on the propagation of the NRSs, reaching a stable state, was also investigated.

La utopía del “lector emancipado” en el proyecto estético de la “Nueva Poesía”
Authors: Rosado Marrero Rogelio
Published: January 2025

El término de “Nueva Poesía” (1966-1995) fue acuñado por Edgardo Antonio Vigo (1928-1997) en el número 20 de la revista Diagonal Cero (diciembre de 1966). En dicho número el poeta argentino desarrolló todo un conjunto de poemas visuales a los que denominó con el título de “Nueva Poesía Platense”. Al ser un proyecto artístico centrado en la experimentación de los dispositivos literarios convencionales y de la forma poética tradicional, las propuestas visuales de Vigo terminan por ser elementos que desarticulan el parámetro de lectura canónico establecido por las instituciones hegemónicas: cuestionar lo que comúnmente denominamos como “poesía”. Con el correr del tiempo, estos planteamientos estéticos fueron compartidos tanto por el artista chileno Guillermo Deisler (1940-1995) como por el escritor uruguayo Clemente Padín (1939); generando así un diálogo interno entre los proyectos personales de estos poetas neovanguardistas, que va desde finales de los sesenta hasta mediados de los noventa. En consecuencia, este trabajo analiza algunas propuestas estéticas radicales de Vigo, Deisler y Padín con la finalidad de demostrar cómo el proyecto de la “Nueva Poesía” configura un tipo de lector cuya participación activa es vital para el cuestionamiento tanto de los cánones literarios vigentes como del sistema totalitario imperante en los años sesenta y setenta en Hispanoamérica. Para ello, nos centraremos no solo en la radicalización que hacen los autores de la propia forma poética, sino también en las instrucciones dejadas por los poetas para el lector en turno. Estos mecanismos discursivos nos dejan entrever cómo el receptor se convierte en una pieza fundamental para el proceso de desarticulación de lo que comúnmente denominamos como “poesía”; lo que propicia una ruptura con los horizontes de lectura impuestos por la tradición misma. Si bien la constitución de un “lector emancipado” termina por ser un ideal utópico de estos autores, su configuración dentro del proyecto de la “Nueva Poesía” permite el desarrollo de un receptor cada más activo y consciente tanto en el plano estético como en la dimensión política.

Background and Aim: In the global pig farming industry, artificial insemination (AI) is widely used to propagate high-quality genetics using processed semen that can be stored for extended periods. However, boar sperm are particularly susceptible to oxidative damage during storage and cryopreservation because of their high polyunsaturated fatty acid content. This study aimed to systematically review the impact of resveratrol (RVT), a potent antioxidant, on the preservation of boar semen.

Materials and Methods: A comprehensive meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Relevant articles were retrieved from databases such as Scopus, ScienceDirect, and PubMed using specific keywords. After a thorough screening, 10 studies were selected for inclusion. Data extracted from these studies included parameters such as sperm motility, viability, DNA integrity, and lipid peroxidation levels.

Results: Resveratrol supplementation in boar semen extenders significantly improved sperm quality under various storage conditions, including waterbath and cooled and frozen semen. RVT’s antioxidative properties effectively reduced reactive oxygen species and prevented oxidative stress-related damage to sperm cells.

Conclusion: The addition of resveratrol to semen extenders enhances the preservation of boar sperm by mitigating oxidative damage, potentially increasing the success rate of AI in the swine industry. This study highlights the need for further research to optimize RVT dosage and application methods for different semen preservation techniques.

Keywords: antioxidant, artificial insemination, boar semen preservation, livestock and gene bank, resveratrol.
The World of Work in the Hungarian Television – The Portrayal of Occupations in Hungarian Fiction Series
Authors:   , Nyéki Andrea Zsuzsanna

Television plays an important role in socialization (Greenberg, 1982; Signorielli, 1993; Wright el al., 1995; Cohen and Weimann, 2000; Hoffner et al., 2008; Gehrau, Brüggemann, Handrup, 2016), and it has a great impact later on too. Viewers gain knowledge from television about new, unfamiliar or unusual things, and they learn from there about the greater social reality to which they do not have direct access. Many television programmes represent occupations through working characters, therefore media has an inevitable role in shaping the public opinion on work-related notions. Work plays a central role in human life. In the Western culture active life is the standard, meaning that the people’s lives are framed by doing paid work. Work affects life in many ways: transforms the environment and shapes people’s identity (Watson, 2008). Occupations determine individuals in the social settings. On social events, for example, people who meet for the first time often ask the question from each-other “What do you do?”. The answer to this question helps people to define who they are in the social context. Participation in certain occupations are culturally bound and socially valued (Phelan and Kinsella, 2009; Unruh, 2004) and occupational titles functions as social categories as well, therefore, they are also a part of social identity.
