Nylon is an alternative material for making membranes considering that nylon is a material that is easy to obtain, cheap and strong. The
electrospinning method is capable of producing nanoscale membranes or filters, compared to other methods. In this research, we prepared
nanomembrane from fishing line material, using the electrospinning method. The fishing line is made of nylon 6 after being identified using FTIR
and TGA. Small pieces of fishing line were dissolved in glacial acetic acid and formic acid in a 1:1 ratio, then the solution was processed on an
electrospinning machine with various voltage variations. Next, the membrane was characterized using FTIR, TGA, SEM and UTM. The membrane
characterization results show that the higher the tension, the thicker the membrane and the higher the tensile strength and elongation of the
membrane. Fiber sizes were produced at tensions of 33.3% (150-200 nm), 30% (200-250 nm), 20% (100-150 nm) and 16.67% (250-300 nm). The
greater the flow rate of the nylon solution, the smaller the percentage of nanofibers. The addition of hydroxyapatite additives increases the tensile
strength of the membrane and increases the percentage of TGA residue.

Introduction: Cybersecurity, also known as computer security or information technology security, is a field dedicated to safeguarding computer
systems, networks, and data from unauthorized access, damage, or disruption. With the rapid advancements in technology and the increasing
reliance on digital infrastructure, cyber threats have become a significant concern for individuals, organizations, and governments worldwide.
cybersecurity involves understanding and countering various cyber threats, such as malware, phishing attacks, data breaches, and ransomware. It
encompasses a wide range of practices and measures, including encryption, firewalls, authentication protocols, intrusion detection systems, and
security awareness training. The primary goal of cybersecurity is to protect sensitive information, maintain the integrity of computer systems,
and ensure the availability of critical services in the face of potential cyber-attacks. As the digital landscape continues to evolve, the importance of
cybersecurity becomes more prominent, making it a critical aspect of modern-day computing and information management.
Research significance: Computer cybersecurity research is of utmost significance as it safeguards critical infrastructure, protects personal data,
defends against evolving cyber threats, preserves national security, fosters economic growth, upholds privacy and individual rights, promotes global
cooperation, and prepares for future challenges. In an increasingly interconnected world, this research plays a pivotal role in ensuring a secure
digital landscape for individuals, organizations, and nations.
Methodology: The PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluations) method is a multi-criteria decision-making
technique used to rank and select alternatives based on various criteria. Developed by J.P. Brans and P. Vincke in the 1980s, PROMETHEE enables
decision-makers to evaluate complex problems with conflicting objectives. The method assesses the relative importance of each criterion, compares
alternatives pairwise, and calculates preference indices to generate a global ranking. By providing a systematic approach to decision-making,
PROMETHEE helps in choosing the most suitable option from a set of alternatives in a wide range of applications, such as business, engineering, and
environmental management.

Unlike TLRs, the regulation of RIG-I-like receptors (RLRs) in preterm labor (PTL) is not well understood. It is unclear if the RLR pathway is activated in uterine tissue during preterm labor and whether this activation is specific to pathogenic agents. This study aimed to elucidate the regulation of the RLR pathway in two preterm labor models. On gestation day 16, preterm labor was induced in mice using LPS for pathogenic inflammation and RU486, a progesterone antagonist, for nonpathogenic inflammation. The rates of preterm labor and fetal viability were assessed, and uterine tissue was collected for ELISA, real-time PCR, immunohistochemistry for RIG-I, and Western blot analysis of RIG-I and downstream proteins. Spontaneous and agonist-induced uterine contractility were also evaluated. Preterm labor was induced 8-10 hours after LPS and 16-18 hours after RU486 administration. Histopathological analysis showed inflammatory changes and neutrophilic infiltration in uterine tissues. Peripheral leukocyte count, TNFα, and IL-6 levels were significantly higher in both LPS- and RU486-treated groups. Agonist-induced uterine contractility was notably reduced in LPS-treated mice. RIG-I mRNA and protein expression were significantly elevated in LPS-treated animals, with decreased RIG-I phosphorylation, while RU486 treatment did not affect these parameters. IRF3 and its phosphorylated form were significantly increased in both preterm labor models. Additionally, interferon-β and lactate levels were elevated in both groups. The findings suggest that the RLR pathway is activated specifically in the pathogenic model of murine preterm labor through increased RIG-I expression and decreased phosphorylation.

Authors: You Ranyilong , Yang Xinyu , Tang Chuyang , Zhou Xinyang
Published: February 2025

The catalytic role of desulfurization fly ash (DFA) was explored as a means to upgrade biomass-derived pyrolysis gas, with a focus on integrating waste valorization and renewable energy production. Soybean straw (SS) was pyrolyzed with DFA to assess the influence on pyrolytic product distribution. The results indicate that DFA notably influenced the yield and quality of pyrolysis gas, with optimal yields achieved at specific DFA concentrations. The study also demonstrated that DFA enhanced the production of methane (CH4) and hydrogen (H2) while reducing carbon monoxide (CO), thereby improving the lower heating value of pyrolysis gas. Fourier-transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM) were employed to characterize the char, showing increased surface area and pore volume due to DFA addition. The study concluded that DFA is an effective catalyst in biomass gasification, providing valuable insights into its catalytic mechanisms and potential for industrial application.
Wood panel defect detection based on improved YOLOv8n
Authors: Li Rui , Zhong Shilu , Yang Xuemei
Published: February 2025

Wood panel surface defect detection is critical to product quality. Traditional detection methods are time-consuming and subjective, and they can lead to economic waste, while deep learning image recognition techniques offer a new approach. However, the accuracy and convergence speed of existing defect detection techniques still require improvement. In this paper, an improved algorithm based on YOLOv8n was designed for accurate detection of wood panel defects. The C-ADown method was designed to replace traditional downsampling, while preserving high-frequency features. The combination of the Dilation-wise Residual Module and multi-scale dilation attention was employed to enhance the multiscale robustness of defect detection. A hybrid encoder was added to improve localization accuracy. The loss function was optimized to improve detection accuracy and convergence speed. Compared to the base YOLOv8 version, the improved model achieved a 6.1% increase in mAP, an 8% increase in recall, and a 3.6% increase in precision, significantly enhancing the model’s detection capabilities.

Authors: Kaur Puneet , Smith Otto R.F. , Leino Tony , Erevik Eilin K. , Griffiths Mark D. , Goudriaan Anneke E. , Pallesen Ståle
Published: February 2025

Objective

The association between depression and gambling disorder (GD) has been well-researched. However, prior research lacks consensus on the temporal association between depression and GD. Furthermore, the extant literature has not explored the nature of the aforementioned relationship using objective research methodology data and large-scale samples. The present study addressed these research gaps by investigating the longitudinal relationship between antidepressant prescriptions and the likelihood of developing GD using registry data over a period of 11 years (2008–2018).

Methods

Data were derived from the Norwegian Patient Registry (NPR) that was matched with data from the Norwegian Prescription Registry (NorPD). The dataset comprised 27,420 individuals, where 5,131 were diagnosed with GD. A binary logistic regression analysis was conducted where individuals with GD were compared with 22,289 individuals matched on age and gender from NPR.

Results

The results show that individuals with antidepressant prescriptions had higher odds of developing GD (OR = 2.80, 95% CI: 2.60–3.01, p < 0.001). Furthermore, males and older adults were found to have a higher likelihood of being diagnosed with GD.

Conclusions

Depression is known to be one of the most common mental health disorders. The findings show that prior antidepressant prescription is associated with GD, which would be in accordance with the escape hypothesis because some individuals gamble to escape dysphoric feelings, such as depression. The study findings add to the existing knowledge on the temporal association of depression and GD. Furthermore, the results also have significant practical implications.
Natural enemy release or biotic resistance? Insect herbivores associated with the exotic Solanum viarum (Solanaceae) and a sympatric native congener in KwaZulu-Natal, South Africa
Authors: Olckers Terence , Msele Kwanele , Egli Daniella
Published: February 2025

Native to South America, Solanum viarum Dunal (tropical soda apple; Solanaceae) is naturalised in several countries globally. The plant is a major invader in the southern USA, but has minor weed status in South Africa. We investigated whether S. viarum has escaped natural enemy pressure or has recruited insect herbivores from the local Solanum flora, which are exerting some level of biotic resistance. Insect species richness and abundance and the resulting levels of herbivory were compared between plants from sympatric populations of S. viarum and the native Solanum dasyphyllum Schumacher and Thonning in the KwaZulu-Natal Midlands. Foliage, floral material, and fruits were collected across seasons from 20 plants of each species and assessed in the laboratory. Despite no significant differences between the two species in the size of the sampled plants, S. viarum displayed significantly lower insect herbivore diversity and abundance and suffered significantly lower levels of damage to its photosynthetic and reproductive tissues. Five of the 11 specialist herbivore species recorded on S. dasyphyllum were associated with S. viarum, but in substantially lower numbers and in fewer samples. The flowerbud-galling moth Scrobipalpa sp. (Gelechiidae), which prevents fruiting in S. dasyphyllum, was absent on S. viarum and indicative of the negligible floral damage on S. viarum. Although the fruit of S. viarum were occasionally utilised by specialist herbivores, seed damage was similarly negligible. Due to its release from specialist natural enemies and with no evidence of biotic resistance, S. viarum may increase in weed status in South Africa.

Citizen Participation in Healthy City Making: An Analysis of Infrastructural Work in a Low‐Income City Area
Authors: Knibbe Mare , Raap Sanne , Horstman Klasien
Published: February 2025

Despite a strong participatory discourse on the healthy city movement, researchers and activists indicate that low‐income groups and city areas often are excluded from participatory urban development and do not benefit from healthy city policies. To better understand the challenges that citizens who promote a healthy urban environment in low‐income areas face, we analyzed the infrastructural work of a citizens’ initiative. We focused on their building of a socio‐material infrastructure in an empty park surrounded by neighborhoods the municipality and other organizations classified as problematic in multiple ways. The infrastructural work consisted of experiments to attract new publics; regular work to revive a neglected garden; and negotiations with the municipality about new trees, natural play elements, and other additions to the park. However, residents’ work was thwarted by institutional control over the neighborhood public and by unreliable bureaucratic interactions that resulted in endless waiting, adaptations, and failures. In this setting, citizens adjusted their infrastructural work by establishing new alliances and engaging in “garden diplomacy” to maintain constructive relationships and a hopeful perspective. The work citizens do to make new local publics should be acknowledged. Moreover, institutional obduracy and bureaucratic ambiguities form a hostile environment for citizen participation. We characterize this hostile environment as shaped by a “residual realism” that reproduces problem neighborhoods. We end with our contribution to a co‐constructionist approach to public participation.
MANAGEMENT OF STUDENT AFFAIRS IN FACED WITH CURRENT EDUCATION CHALLENGES IN MALAYSIA
Authors: Othman Rosmawati binti Yusof , Yusoff Zuraidah Juliana Mohamad
Published: February 2025

The school was created to systematically implement the education process based on the National Education Philosophy (FPK) to develop the potential of students in a holistic and integrated manner. School is also a place to shape the personality, discipline and potential of students through systematic student affairs management (HEM). Each individual in the school organization is given responsibilities that need to be carried out as best as possible. Nevertheless, the Malaysian Ministry of Education (KPM) found that there is an issue among educators, which is the problem of role ambiguity which has had an impact on the level of student discipline and school achievement in the academic field. Therefore, this study was conducted to identify the role and scope of tasks of the HEM unit through a new approach which is the HEM Management Model which was formed as a result of the combination of two approaches introduced by the KPM namely the Malaysian School Governance (MySG) and the second wave Education Quality Standard (SKPMg2) in order to be a reference for all school members. With this model in place, the school management can reduce the ambiguity in the implementation of HEM duties in various aspects including student discipline management, hygiene, safety and health (3K) management, scholarship management, guidance and counseling management, Textbook Loan Scheme (SPBT) management and so on. A clear level of understanding for each task of the HEM unit in addition to the implementation of regulations and specialized circular letters (SPI) by the Ministry of Education and Culture will create an efficient management structure to face various educational challenges today.

Where Could Prince Izyaslav Volodymyrovych Escape from Terebovlia in September 1210/1211?
Authors: Voloshchuk Myroslav
Published: February 2025

This paper is an attempt to identify one of the witnesses of executing in 1212 a diploma by the Prince of Kalisz Władysław Odonic for the Prussian bishop Christian with the subsequent granting of the village of Ceków to the bishop. The diploma mentions a certain Isizlaus among alii nobiles. As we cautiously suggest, that was the son of the former Galician Prince Volodymyr Igorevych – Izyaslav, the Prince of Terebovlia, in the years 1209/1210–1210/1211. After a victorious campaign in August – September 1210/1211 against the Igorids brothers, settled in the Halych land, the Hungarian troops led by Palatine Poth, reinforced by the Kraków, Sandomierz, and Volhynian troops, captured Svyatoslav and Roman Igorids and sold them to the Galician boyars, after which the brothers were hanged together with their families. Unlike the Igorids, Prince Volodymyr and his son Izyaslav managed to escape. While sources do not report anything about Izyaslav for the next few decades, the appearance of the person named Isizlaus at the court of Władysław Odonic in 1212 may not be coincidental. We assume that this may have been Prince Izyaslav Volodymyrovych, since Prince Władysław was his uncle ‘on the distaff side’ according to the genealogical relations with the Galician Rostislavovids.

Yellow mealworms, Tenebrio molitor, are increasingly being used as a source of protein for humans, as well as for feeding animals. However, as with any other type of livestock, yellow mealworms can be affected by diseases, which can lead to reduced productivity. In this chapter, the authors review recent research and describe common diseases that affect yellow mealworms and their causal agents, such as bacteria, fungi, viruses, and other pathogens like microsporidians, nematodes, and gregarines. Subsequently, they discuss methods that, both now and in the future, could play a role in controlling the pathogens. While there already exists protocols to facilitate the development of good hygienic practices, the authors also explore techniques with the prospects of improving insect immunity such as selective breeding, immune priming and the use of probiotics, all of which could protect the insects against existing and as yet unknown pathogenic threats.

Published: February 2025

Community members returning from incarceration experience serious health disparities, which intensified during the COVID-19 pandemic. In response, community health workers with lived experience of incarceration in the Transitions Clinic Network established a California reentry health care hotline to support time-sensitive linkages to postrelease medical care. From June 2020 to June 2023, the hotline supported 1276 people transitioning from incarceration. Lessons from this peer-led public health intervention are relevant for states utilizing Medicaid waivers to improve health equity for justice-involved populations. ( Am J Public Health.

Published: February 2025

Fluoride (F⁻) toxicity has become a significant environmental and public health concern globally. Microbial defluoridation offers a promising approach to restoring soil health, increasing crop yields, and minimizing fluoride bioaccumulation in the food chain. In the present experiment, seven bacteria with varied levels of fluoride resistance were screened out in vitro using tryptone soya agar medium supplemented with different grades of Sodium Fluoride (NaF) from the composite topsoil (0–0.2 m depth) of fluoride-rich rice fields of three blocks (Arsha, Jhalda-I, and Joypur) of the Purulia district, West Bengal, India. Using NCBI- BLAST and 16S rDNA barcode sequence-based molecular phylogeny, the seven isolates were identified as Aeromonas aquatica strain KPNA_FR1 (GenBank Acc. PP957426), Bacillus pumilus strain KPNA_FR2 (GenBank Acc. PP948725), Enterobacter sp. Strain KPNA_FR3 (GenBank Acc. PP948726), Enterobacter ludwigii strain KPNA_FR4 (GenBank Acc. PP948727), Priestia aryabhattai strain KPNA_FR5 (GenBank Acc. PP948728) Enterobacter sp. strain KPNA_FR6 (GenBank Acc. PP948729), Bacillus pumilus strain and KPNA_FR7 (GenBank Acc. PP948730). Out of these seven isolates, the most Fluoride tolerant bacterium Enterobacter ludwigii strain KPNA_FR4 can tolerate a maximum of 11,250 ppm NaF in vitro and exhibited ~ 78% defluoridation capacity from medium. The plant growth-promoting efficiency of KPNA_FR4 including other isolates concerning the solubilzation of phosphate (123.67 ± 13.41 ppm), potassium (2.49 ± 0.10 ppm) and zinc (50.80 ± 5.38 ppm) have also been reported. Thus, the isolated fluoride-resistant bacteria, having significant potential as fluoride bioremediator and biofertilizers, may be used to mitigate soil fluoride toxicity sustainably and to increase agricultural productivity as well.
Effect of Adding Machining Swarf of Brass Alloy on the Microstructure and Toughness of Gray Cast Iron

Published: February 2025

In this study, the effects of brass machining swarfs with different weight percentages on cast iron were investigated. The addition of 1 wt.% swarf contributed to the finer characteristics of the graphites categorized as types A and E while simultaneously increasing the quantity of pearlite grains present. When the amount of swarfs was increased to 3 and 5 wt.%, the graphite became finer due to rapid solidification, and a transitional interface of pearlite was also observed. The addition of 1 wt.% swarf to the cast iron led to an increase in hardness from 200 HB to 212 HB. However, as the swarf content increased, a reduction in hardness was observed, with the composites containing 3 wt.% and 5 wt.% swarf achieving hardness values of 197 HB and 185 HB, respectively. This phenomenon is linked to the presence of the softer brass phase in the composite structure. The microhardness of these swarfs was measured at approximately 99 Vickers, which was the minimum value. The soft phase of the swarf had a positive effect on increasing the impact energy due to ductile fracture, whereas the absence of the swarf led to brittle fracture in gray cast iron and the 1 wt.% composite. The impact energies of graycast iron and the 1 wt.%, 3 wt.% and 5 wt.% composites were measured to be 3, 4.2, 5.7, and 10.6 Joules, respectively.

Published: February 2025

Background

The latest advancement of artificial intelligence (AI) is generative pretrained transformer large language models (LLMs). They have been trained on massive amounts of text, enabling humanlike and semantical responses to text-based inputs and requests. Foreshadowing numerous possible applications in various fields, the potential of such tools for medical data integration and clinical decision-making is not yet clear.

Objective

In this study, we investigate the potential of LLMs in report-based medical decision-making on the example of acute ischemic stroke (AIS), where clinical and image-based information may indicate an immediate need for mechanical thrombectomy (MT). The purpose was to elucidate the feasibility of integrating radiology report data and other clinical information in the context of therapy decision-making using LLMs.

Methods

A hundred patients with AIS were retrospectively included, for which 50% (50/100) was indicated for MT, whereas the other 50% (50/100) was not. The LLM was provided with the computed tomography report, information on neurological symptoms and onset, and patients’ age. The performance of the AI decision-making model was compared with an expert consensus regarding the binary determination of MT indication, for which sensitivity, specificity, and accuracy were calculated.

Results

The AI model had an overall accuracy of 88%, with a specificity of 96% and a sensitivity of 80%. The area under the curve for the report-based MT decision was 0.92.

Conclusions

The LLM achieved promising accuracy in determining the eligibility of patients with AIS for MT based on radiology reports and clinical information. Our results underscore the potential of LLMs for radiological and medical data integration. This investigation should serve as a stimulus for further clinical applications of LLMs, in which this AI should be used as an augmented supporting system for human decision-making.
Deep Convolutional Neural Network Based for Early Recognition of Diabetic Retinopathy: A Comprehensive Review
Authors: Sonekar Dr. S.V.
Published: February 2025

Diabetes-related retinopathy (DR), a common side effect of diabetes mellitus, creates lesions in the rear of the eye,
impairing vision. If it is not diagnosed in time, it may cause paralysis. Unfortunately, there is currently no known cure for DR;
the only option is avoidance. Early identification and management of DR are critical for rapidly minimizing the risk of visual
loss. DR retina fundus images must be physically diagnosed by an ophthalmologist, that is more expensive, time-consuming,
more error-prone then computer-aided diagnosis methods. Deep learning is now rising to become one of the favored methods for
performance improvement, particularly in medical image categorization and decoding. Convolutional neural networks that are
artificial are used to evaluate healthcare images since they are an effective learning tool. The most sophisticated approaches for
categorizing and detecting DR color photographs of the fundus using deep learning algorithms were reviewed and analyzed to
the purpose of this study. Additionally, the color of the fundus macular DR data was analyzed. Additionally, certain challenging
situations requiring additional study are addressed

Voltage dips and swells detection by sliding fast Fourier transform: Possibilities for application in modern distribution networks
Authors: Banjanin Mladen , Milovanović Miloš , Radosavljević Jordan
Published: February 2025

This paper deals with applying the sliding Fast Fourier Transform analysis to detect voltage dips and swells in modern distribution networks. Significant odd and even voltage harmonics appear during voltage dips and swells, and they can be used to detect these events. Since the voltage waveshape during the dips and swells have the same harmonic content, the separation of these events can be done by calculating the angles of the voltage harmonics at the moment of the event. In the case of voltage swells phase angles of the 1st and the higher order harmonics have the same polarity, while in the case of voltage dips phase angles of the 1st and of the higher order harmonics have the opposite polarity. The presented approach is verified by analyzing mathematical signals and signals measured in real distribution networks with renewable sources. The limitation of the analyzed method is that the amplitude of voltage variation during the dip or swell in a real distribution network cannot be reliably associated with the calculated values of voltage harmonics. This limitation can be overcome by considering the value of 1st voltage harmonic, or RMS voltage value calculated for one cycle or half cycle of the voltage wave.

The existing indicators of the industry incident «Improving the efficiency of managing the system of measures to reduce adult mortality», which are derived from the number of fatalities in road accidents, do not reflect the overall picture of mortality from injuries and external causes in the Russian Federation. In this regard, in order to reduce mortality from manageable causes, it seems appropriate to use indicators calculated in the group of victims with combined, multiple and isolated injuries accompanied by shock. The indicators should characterize compliance with routing for the specified group of victims and the timeliness of the start of anti-shock therapy. The purpose of the study is considering the feasibility of making changes to the structure of the industry incident in terms of indicators of mortality from injuries and external causes. Materials and methods. Mortality rates from injuries and external causes in the Russian Federation for the period 2020-2023 were studied, and proposals were developed to improve their monitoring within the framework of an industry incident. The results of the study. Mortality from injuries and external causes in the Russian Federation continues to be high: in 2023, this figure was 107.1 per 100,000 population, including mortality from road accidents — 9.2 per 100,000 population (8.6%). In order to improve the efficiency of managing the system of measures to reduce mortality in the adult population, it is advisable to include in the structure of the industry Incident indicators that allow assessing compliance with predetermined routing and the timeliness of providing specialized medical care to all victims with combined, multiple and isolated injuries accompanied by shock.

Magnetic materials exhibiting bistability at ambient condition are appealing for application in high-density memory, data storage, sensing and switches devices. Octacyanometallates have been extensively studied as building blocks for constructing novel molecular magnetic materials with exciting physical properties. Here, we have designed and synthesized two cyanide bridged 2D hexagonal networks using octacyanotungstate(V) building block where {[W(CN)8]2[Co(V-im)4]3}n(1) undergoes a single-crystal to single-crystal (SC-SC) structural transformation to form {[W(CN)8]2[Co(V-im)4]2[Co(V-im)2(DMF)2].4H2O}n (2). Complex 1 exhibits reversible thermo-induced metal-to-metal electron transfer (MMET) (T1/2 = 176 K) with a 12 K thermal hysteresis width while complex 2 exhibits near ambient temperature two-step MMET (heating: T1/2(1) 324 K, T1/2(2) 340 K; cooling: T1/2(1) 286 K, T1/2(2) 232 K) with a hysteresis width of 4 and 15 K respectively. Interestingly, light-induced reversible ON/OFF MMET has also been observed for both complexes (1 and 2) using 808 nm and 900 nm lights (ON mode) and 405 and 635 (OFF mode) respectively, converting the low-temperature diamagnetic {WIVLS-CN-CoIIILS} ground-state into the metastable paramagnetic {WVLS-CN-CoIIHS} phase and vice-versa . X-ray absorption spectroscopy was performed in order to investigate the local electronic structure and magnetization associated with the MMET between the W and Co metal centres.

N-acylhydrazones (NAH) are privileged structures in chemistry and medicinal chemistry. The alkylation of NAH can profoundly alter the structural properties of this subunit. In this study, we describe the conformational effects of N- and C-methylated N-acylhydrazones derivatives, combining theoretical and experimental data analysis. Methylation of NAH significantly affects the structure through electronic influences and changes in the lowest energy conformation. The introduction of the methyl group induces a substantial steric impact, evident from the alterations in the conjugation of the NAH framework as analyzed by theoretical studies and nuclear magnetic resonance (NMR) data. Among the series, the compound with two methyl groups is the most anomalous. Despite having two methyl groups, this compound exhibits greater polarity than the compound with a single methyl group on the amide nitrogen, as determined by thin-layer chromatography. This study contributes to a deeper understanding of the chemical properties of alkylated NAH derivatives and can guide their application in various branches of chemistry and medicinal chemistry.

The negative impact of plastic waste on the environment is a serious issue for the future. Adding cleavable bonds in the polymer backbone can help to impart degradability properties. To this end, radical ring opening polymerization (rROP) of-fers a very attractive way through radical copolymerization with vinyl monomers. Thionolactones, one of the various cyclic monomers that can be used in rROP, are promising structures due to the efficiency of the C=S bond in acting as a radical acceptor. In this work, we used DFT calculations to better understand the effects of different substituents on the radical reac-tivity of thionolactones (dibenzo[c,e]oxepane-5-thione DOT derivatives) already described as more or less effective for copol-ymerization with vinyl monomers in order to adjust the reactivity of these thionolactones. To carry out these calculations, we focused on the value of the transfer constant ktr and its relationship to the propagation constant kp of the vinyl monomer. The calculations performed subsequently on 7-phenyloxepane-2-thione (POT) derivatives highlighted that electron-donating groups inserted in para-position on the phenyl ring should improve the copolymerization efficiency with acrylate derivatives and in contrary electron-withdrawing groups should lead to more important compositional drift during styrene and acrylate copolymerization. Although POT derivatives bearing electro-donating groups could not be prepared, the preparation of those with CF3 and NO2 groups was successfully achieved. Experimental copolymerization of these two thionolactones with sty-rene and isobornyl acrylate are in good agreement with the calculations. This result confirmed the versatility and relevance of our calculation approach to account for the reactivity of thionolactones.

FROM SUBJUGATION TO LIBERATION: THE PLIGHT OF NAMBUDIRI WOMEN AND THE REFORM MOVEMENTS IN KERALA
Authors: Santhan Sunitha
Published: February 2025

The Namboothiri community, once the dominant Brahmin caste of Kerala, upheld a rigid patriarchal structure that severely restricted the rights and freedoms of its women. Namboothiri women, particularly the Antharjanams (women confined within the household), endured extreme social limitations, including seclusion, lack of education, and rigid marital norms. Their lives were dictated by oppressive customs, such as ill-fated marriages, widowhood asceticism, and social taboos that denied them personal agency. However, by the late 19th and early 20th centuries, Kerala witnessed significant reform movements aimed at dismantling these oppressive structures. Organizations like the Yogakshema Sabha, along with the efforts of progressive leaders and writers, played a crucial role in advocating for women's education, social mobility, and legal rights. This article explores the transformation of Namboothiri women from a state of subjugation to active participation in societal change. It highlights key reform initiatives, the resistance faced, and the eventual impact on gender dynamics within the community.
संगीत का हिंदू और सिख धर्म के साथ आध्यात्मिक संबंध
