Tracing Early Enrichment Pathways: Chemical and Chemodynamical Analysis of Two CEMP-no Stars**Based on the data collected from HDS/SUBARU
We present a detailed high-resolution spectroscopic and chemodynamic analysis of two carbon stars, HE 1148?0037 and HE 1246?1344, using SUBARU High Dispersion Spectrograph spectra (R ? 50,000). Our analysis confirms that both stars are extremely metal-poor and belong to the Carbon-Enhanced Metal-Poor (CEMP)-no class ([C/Fe] > 0.70 and [Ba/Fe] < ?1.0). Both of the stars are found to be group II CEMP-no stars in the A(C) versus [Fe/H] diagram. While both stars exhibit slightly enhanced ?-elements (Ca, Sc), their Mg, Fe-peak, and neutron-capture element abundances show distinct trends, indicating different progenitor pathways. From [O/Fe] and [Sr/Ba] ratios, we identify both metal-poor asymptotic giant branch stars and fast-rotating massive stars as potential progenitors. Further elemental abundance analysis suggests a multienrichment origin for these stars. Kinematic analysis reveals that HE 1148?0037 belongs to the halo, with a spatial velocity of 464.99 14 km s?1. Orbital calculations show that HE 1148?0037 follows a retrograde orbit and is associated with the high-energy retrograde halo, likely a member of the Iitoi substructure. In contrast, HE 1246?1344 follows a prograde orbit and is linked to Gaia-Sausage/Enceladus. 2026. The Author(s). Published by the American Astronomical Society.

High-resolution spectroscopy of HE 0225?0546 and HE 1153?0518: probing the progenitors through abundance patterns and kinematics
We present the results of a high-resolution (SUBARU/HDS, R ? 50 000) spectroscopic study of two metal-poor stars, HE 0225 ?0546 and HE 1153 ?0518. This marks the first such detailed analysis for both objects. Our findings reveal that HE 0225 ?0546 is extremely metal-poor with [Fe/H] ??3.03, while HE 1153 ?0518 is very metal-poor with [Fe/H] ??2.80. Both stars exhibit enhancements in carbon and neutron-capture elements and formally satisfy the criteria for carbon-enhanced metal- poor (CEMP) classification. Although their [Ba/Eu] and [La/Eu] ratios do not allow a secure assignment to any specific CEMP sub-class, the estimated [Ba/Eu] and [Eu/Fe] ratios indicate that both stars fall into the r-II star category. Distinct abundance patterns between the two stars suggest different nucleosynthetic histories. HE 0225 ?0546 shows strong enhancement in Fe-peak elements, while HE 1153 ?0518 is mildly deficient in the same. Both stars are ?-enhanced, though the level of enhancement varies. These results indicate pollution by multiple progenitor channels. Abundance ratios imply that HE 0225 ?0546 is likely enriched by fast-rotating massive stars (FRMS), whereas HE 1153 ?0518 shows signatures consistent with asymptotic giant branch (AGB) star enrichment. Kinematic analyses place both stars in the high-energy, prograde component of the Galactic halo. HE 0225 ?0546 has an apogalactic distance (rapo ) of ?31.8 kpc, placing it in the outer halo, while HE 1153 ?0518 lies closer to the boundary of the inner and outer halo with rapo ?13.8 kpc. Both stars show kinematic coherence with the Sagittarius substructure, suggesting a possible extragalactic origin. The Author(s) 2025.

High-resolution spectral analysis of three high-latitude carbon stars
We present the results of a detailed high-resolution spectroscopic analysis (SUBARU/HDS spectra, R 50 000) of three faint high-latitude carbon stars HE 1104 0957, HE 1205 0521, and HE 1244 3036. Our estimated metallicity for these objects is 2.96, 2.63, and 2.49, respectively. The surface chemical compositions of the objects are found to be characterised by enhanced carbon and heavy elements, such as Y, Ba, La, and Ce. Using the classification criteria for carbon-enhanced metal-poor (CEMP) stars the objects HE 1104 0957 and HE 1205 0521 could not be classified into any known CEMP sub-classes, whereas the object HE 1244 3036 is found to be likely a CEMP-s star. The observed abundance patterns in HE 1244 3036 are also found to match well with the yields of a 2 M AGB star with [Fe/H] = 2.50. Although our kinematic analysis indicates that the objects belong to the halo population, the elemental abundance ratios of HE 1104 0957 and HE 1205 0521 do not match well with those of typical halo objects. Estimated elemental abundances are presented, and kinematic properties of the stars are discussed. The Author(s), 2025. -

Psychological Experiences and Perceived Social Support: A Study on Indian Mothers of Children with Type 1 Diabetes
Introduction: Mothers are often the primary caregivers of children in Indian homes. Mothers of children with Type 1 diabetes experience an emotional toll of this challenging responsibility that the lack of social support can exacerbate. Health care for children with Type 1 diabetes in India commonly addresses the medical condition and its associated symptoms, whereas mothers, who bear the primary responsibility of the childrens care, are most often neglected. This study aimed to understand the psychological experiences and perceived social support of Indian mothers whose children are diagnosed with Type 1 diabetes. Methods: This phenomenological research was conducted using semi-structured interviews with mothers using purposive sampling between the ages of 24 and 45 years (n = 13) and analyzed using thematic analysis. The data analysis and collection were done between January 2022 and December 2022. Results: Thematic analysis revealed six main themes of psychological distress, multifold strain, poor Type 1 diabetes mellitus education and stigma, need for social and familial support, caregiver burden, and coping. The findings from this research suggest that such experiences can make it difficult for them to cope with their childs diabetes and have a negative impact on their mental health. Conclusion: This study highlights the need for culture-appropriate interventions to address the social and emotional needs of such mothers. It is essential to educate families and the community as a whole about the needs of both mothers and children with Type 1 diabetes. 2023 Asian Journal of Social Health and Behavior. -

Occurrence, identification, and decontamination of potential mycotoxins in fruits and fruit by-products
The incidence of aflatoxins, ochratoxin A, and patulin in fruits and processed fruit products has been ever more challenging and gained additional focus on ecofriendly mitigation strategies. The onset of these toxins is due to several factors involving insect attacks, agricultural practices, and climate change. Acute and chronic health hazards are clinically proven after consuming contaminated foodstuffs, even at lower concentrations of mycotoxins. Synergistic, masked, and substantial occurrence in fruit matrices increase their complexity in detection and detoxification; apparently, this article reviewed the available information on the occurrence of mycotoxins in several fruits and their products, focused on the conventional and advanced methods of identification, quantification, and decontamination techniques. Strengthening and implementing stringent international and national guidelines are required for impactful, tangible measures in the future. Nevertheless, controlling the mycotoxins in fruits will certainly be challenging for scientists. Therefore, more impactful technologies are still needed to eliminate the toxins at the threshold level of the food chain and ensure sustainable global food safety. 2023 The Authors.

Potential of insect-based milk moiety from Pacific beetle cockroach, Diploptera punctata (Blattodea): Insights as superfood
Diploptera punctata is a viviparous cockroach and secretes a concoction of glycosylated proteins as a basis of nutrition for developing embryos termed as cockroach milk. The milk proteins were identified as the lipocalin-like milk proteins (Lili-Mip) which are present in the brood sac of the gestated female D. punctata. Blotting techniques and RNA transcriptome assays have reported analogous Lili-Mip in the midgut of D. puncta embryos, which proved the ingestion during development inside brood sac. Thermodynamics and kinetic studies augmented the stability of the milk crystals and their controlled release mechanism of sustenance. Gene ontogeny reported the evolution of the ovoviviparous to viviparous due to selective pressures posed during the development stages of the embryos. Molecular simulation modelling studied unveiled the binding efficacies of the milk protein to build strong affiliates to the ligands to form a stable milk protein complex. Ahead of its nutritional benefits, cockroach milk also offers environmental advantages compared to traditional dairy and plant-based milk production. Nevertheless, there are still important hurdles to overcome to include this unconventional superfood as staple in human diets which are also discussed in the review. This review explored the existing molecular, evolutionary and biochemical insights for understanding the phenomena of the production of milk crystals and addressed the research gaps for developing a novel nutrient prospective from insect source. 2024 Korean Society of Applied Entomology -
Electrochemical non-enzymatic strategy with green synthesized Fe2O3CuO nanocomposite for detection of amiprofos-methyl herbicide in industrial effluents and soils
Iron oxide-Copper oxide nanoparticles composite (Fe2O3CuO NPs) was synthesized through a green phytosynthetic approach using Ocimum sanctum Linn (commonly known as Tulsi) leaf extract. The evaluation of electrocatalytic properties were evaluated by carrying out electrochemical detection of amiprofos-methyl (APM), an organophosphorus herbicide. It is moderately toxic to mammals and aquatic biodiversity and is considered to be an acetylcholinesterase inhibitor. The presence of specific natural phytochemicals such as eugenol, naringenin, apigenin, quercetin, and high amount of ascorbic acid in the aqueous extract of Ocimum sanctum Linn plant parts, has been widely used for the synthesis of various metallic nanoparticles where these compounds serve as reducing, stabilizing, and capping agents. The synthesized Fe2O3CuO NPs were characterized using scanning electron microscope (SEM), energy dispersive X-ray analysis (EDX), X-ray diffraction analysis (XRD), UVVis spectroscopy, Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The modified electrode was electrochemically characterized by cyclic voltammetry and differential pulse voltammetry (DPV) techniques for the detection of APM. The electrochemical signals have increased by three folds in the detection of APM with Fe2O3CuO nanocomposite compared to the bare glassy carbon electrode. The electrochemical sensor showed a linear range of 0.05 to 30 g/mL with a limit of detection of 0.0065 g/mL. The developed electrochemical sensor was successfully applied for the detection of APM in different water and soil samples with recoveries ranging from 96.00?99.00%. The electrode showed good stability and reproducibility over a period of 10 days with a 95% of peak current than the former. The newly synthesized nanoparticles, thus, proved to be an interesting material for electrochemical and biological studies. 2023 The Authors -
INCLUSIVE LAW SCHOOL CLINICS: Institutionalizing Effective and Accountable Justice for All
Poor people are often denied access to the courts due to expensive legal fees. Preventing free access to justice violates a fundamental constitutional principle and universal international norms. The recognition of access to justice and the rule of law as outcomes and facilitators of sustainable development is a unique feature of the 2030 Agenda. This study shows that providing affordable and timely access to justice institutions and legal aid services will help achieve the Sustainable Development Goals (SDG) 16 targets of peace, justice, and strong institutions. Indian law school clinics have a unique opportunity to achieve the goal through institutionalized clinical legal education. The Advocates Act of 1961 requires an amendment to allow law students and faculty to represent pro bono clients. The study infers that completely institutionalizing the law school legal aid clinics as part of clinical legal education is a powerful platform to promote equal access to justice to all. 2021, Dharma Research Association.
