The study aims to understand the traditional healthcare management of the newborns of the Parengi Porja tribe. The Parengi Porja tribe is a Particularly Vulnerable Tribal Group (PVTG) that inhabits the Eastern Ghats, which is a continuous high hilly region of Visakhapatnam district, Andhra Pradesh, India. The members of this tribe strongly believe that the earliest weeks of a newborn's life is the time for the greatest probability of death and disability. To avoid these misfortunes, they strictly follow the traditional healthcare regimen for newborns, which has significant socio-cultural importance. For this study, 105 neonates were purposively selected, and their mothers were interviewed for data collection. The research data were analysed by qualitative methods that included participant observation, in-depth interviews and focus group discussion. The collected data were repeatedly cross-checked with other elderly female members like grandmothers, and sutranimaizi (traditional birth attendant [TBA]) through interviews to strengthen the efficiency and authenticity of the data. The findings of the study show that this tribal population has its understanding of the management of neonatal health, which is socio-culturally ingrained, sanctioned and transmitted through generations.

The enhanced photocatalytic process of GMNT NCs was achieved by wet impregnation. The resulting sample was examined using numerous analytical techniques to determine its composition, morphology, structure, and optical properties. GMNT photocatalyst showed impressive photocatalytic degradation efficiency (91.75%) over RhB dye in 100 min, when exposed by visible illumination. The photoreaction rate constant of GMNT ternary PCs (0.0233 min−1) was 6.2 times faster than bare GCN (0.0037 min−1), GMS (0.0055 min−1), and GCNT (0.0124 min−1) against RhB dye. Besides, they have considerable stability against RhB dye degradation after five cycles. A trapping experiment with a variety of scavengers also reveals that photogenerated charge carriers hole pair and ⋅O2− radicals play a prominent role in the photodegradation process. GMNT nanocomposite has been shown to enhance photocatalytic performance by suppressing e−–h+ pair separation and recombination efficiency. Hence, GMNT PCs have shown high potential for various environmental applications, including wastewater treatment. [ABSTRACT FROM AUTHOR]

Herein, the MMn2O4 and MMn2O4/rGO (M = Ni, Co) samples were synthesized using co-precipitation and wet impregnation methods. XRD analysis showed the high purity and good crystallinity of the synthesized powders. FESEM analysis revealed the formation of pyramid-like structures and a good intimate mixture with rGO in the nanocomposite samples. Gas sensors were fabricated with pure and nanocomposite structures for the sensing of ammonia gas. The CoMn2O4/rGO nanocomposite sample achieved a higher sensitivity (S = 3.5) with shorter response/recovery (140 s/83 s) behavior in room temperature at 100 ppm of NH3. The stability and selectivity of the CoMn2O4/rGO nanocomposite gas sensor were examined. The preferable sensing mechanism of CoMn2O4/rGO nanocomposite towards the detection of NH3 was discussed.

A simple wet impregnation method has been proposed to prepare highly efficient different weight percentage (25:75, 50:50, and 75:25) of g-C3N4–ZnO nanocomposites. The morphology, chemical composition, structure, functional group, and optical properties of the prepared samples were examined through FESEM, HRTEM, EDAX, XRD, FTIR, UV, and PL techniques. The photocatalytic performance of 75 wt% g-C3N4–25 wt% ZnO nanocomposite exhibited higher photocatalytic activity as compared to other samples. The scavenger test was showed to study the role of different radicals in degrading the dye pollutants. The possible photocatalytic performance of 75 wt% g-C3N4–25 wt% ZnO nanocomposite has been proposed. [ABSTRACT FROM AUTHOR]

In this study, CoFe2O4 and CoFe2O4/rGO samples were synthesized using co-precipitation and wet impregnation methods, respectively, and their sensing capabilities were assessed for ammonia gas detection at room temperature. The formation of the CoFe2O4/rGO nanocomposite was thoroughly examined through various analytical techniques, revealing its enhanced properties. Notably, the CoFe2O4/rGO nanocomposite exhibited significantly higher sensitivity compared to pure CoFe2O4, with a calculated sensitivity value of 1.098. The material also demonstrated rapid response and recovery times of 61 s and 143 s, respectively, for a 100-ppm ammonia gas concentration at room temperature. These findings highlight the potential of the CoFe2O4/rGO nanocomposite for efficient and sensitive gas sensing applications.
