Heritagizing the Maestro

Bhupen Hazarika was a multifaceted personality known for his contributions as a singer, songwriter, composer, filmmaker, writer, and social activist from Assam, a state in the north-eastern part of India. To honour his life and works, a memorial site is constructed in the Jalukbari area of Assam. The site is called ‘Dr Bhupen Hazarika Samadhikshetra’. It is located in Guwahati city, near Gauhati University, in the state of Assam, India. The literal meaning of the Assamese words Samadhikshetra is a burial site. Through empirical research, the paper investigates the conceptual framework of heritagization as applied to Dr Hazarika’s legacy, focusing on preserving, maintaining, and celebrating his contributions to society. The study emphasises the role of the memorial site, as a tangible example of Dr Hazarika’s cultural relevance by delving further into its architectural design, symbolic elements, and commemorative features. Beyond these tangible aspects, the study also addresses the intangible values, identity and collective memories that the site evokes and preserves. The paper also explores the close interaction between the cultural and constructed heritage of the site, emphasising the need for a holistic strategy to protect and preserve the cultural past. Despite controversies and challenges over selecting the last resting place of Dr Hazarika, the Samadhikshetra stands as a tribute to his lasting influence and gratitude for his artistic legacy. Through commemorative events and ongoing public engagement, the memorial site continues to serve as a sacred space where Dr Hazarika’s spirit can live on and inspire future generations.

Potential distribution of rice thrips (Stenchaetothrips biformis) in India under changing climate

Sudden outbreaks of agricultural pests are increasing in India due to the growing prominence of environmental issues like global warming, the occurrence of weather extremes, and hydrological extremes. Climate change impacts the developmental rates and population dynamics of agricultural pests. As rice is a staple food widely used in India, it often suffers intensive damage by various pests, leading to a considerable decrease in crop yield. One of the most common pests in rice fields in India and neighboring countries is the rice thrips (Stenchaetothrips biformis). However, the degree of pest infestation of rice crops under climate change scenarios is poorly known. Therefore, this study aimed to understand the potential geographical distribution of the rice thrips in India for future scenarios using the MaxEnt modeling framework. Future projections from global climate models (GCMs), such as HadGEM3-GC31 and MPI-ESMI-2, are used to predict the most affected regions in 2050 under three greenhouse gas emission scenarios: SSP1-2.6, SSP3-4.5, and SSP5-8.5. The results from the MaxEnt indicate that the southern and northeastern parts of India will be highly affected by rice thrips in 2050. The affected number of districts are found to be 256, 330 and 313 under SSP1-2.6, SSP3-4.5, and SSP5-8.5 scenarios, respectively. It has been observed that the maximum temperature is the most influential climatic parameter for the geographical distribution of rice thrips, followed by the annual mean and minimum temperatures. It can be concluded from these results that the elevated temperature enhances the growth and distribution of rice thrips.

Assessment of active tectonics of the Tripura-Mizoram fold belt (Surma Basin), North East India

The Tripura-Mizoram fold belt is situated in the north-eastern part of India. Northeastern Himalaya including this region is tectonically very active, partly petroliferous, and has international attention from academicians and industry persons. This study aims at locating areas of recent tectonic vulnerability. Drainage networks are proxies of active faulting. Changes in geomorphic indices e.g., long profile analysis, basin-scale parameters, stream length gradient index and steepness index along the rivers in the eighteen watersheds extracted within the study area are evaluated. The Index of active tectonics (IAT) derived from the basin-scale parameters is classified into five classes: Class 1 (IAT =1.875–2.000), Class 2 (IAT = 2.001-2.375 ), Class 3 (IAT = 2.376-2.750), and Class 4 (IAT = 2.751-3.250) and Class 5 (IAT = 3.000‐3.320). Class 1 indicates the highest activity of tectonics. The tectonic sensitivity is also marked in micro-scale where rivers cross lineaments / faults. Elevations from source to mouth of individual consequent rivers of each watershed indicate the most vulnerable sections where the channels run along and across the faults or lineaments in watersheds 2, 14 and 15. The computed R2 values and the IAT identify watershed 2 and watershed 15 as the tectonically most active. Well-bore stability issue from the Petroleum mining lease (PML) blocks needs to be taken care from watershed 2, 3 and 15.

Phytoliths in bamboos from eastern and north-eastern India: Implications in distinguishing different ecoclimatic conditions and in deciphering Late Holocene climate variability

To develop a phytolith (biogenic silica) reference and to understand the eco-climatic indicative values of some grass silica short cells (GSSCs) occurring in the bamboos (Bambusoideae grasses), one of the chief floral components of eastern and north-eastern parts of India, we studied 44 modern bambusoid grasses and 26 surface soils from different eco-climatic zones covering both the plains and mountainous regions. Of the diverse phytoliths retrieved from the bamboos, Saddle tall and Saddle collapsed were the most abundant types (except in Yushania maling) and these types were also common in surface soil phytolith assemblages of the eastern and north-eastern parts of India. To assess the environmental sensitivity of most consistent morphotypes, we categorized two commonly occurring GSSC morphotypes namely Saddle tall into three groups based on their length and Saddle collapsed into two groups based on their length to width ratio respectively. Pearson’s correlation analysis, principal component analysis (PCA), and redundancy analysis (RDA) were used to understand if these morphotypes could distinguish different eco-climatic conditions. Variability of Saddle tall and Saddle collapsed types (both morphometric and abundance) in bamboos growing in these parts of India is a function of mean precipitation of the wettest quarter (MPWeQ) and mean temperature of the driest quarter (MTDQ). The present results served as a baseline for reevaluating the interpretations of a Late-Holocene fossil phytolith record from the eastern Himalaya further validating the potential of Saddle tall and Saddle collapsed types in reconstructing past climate variability in a wide geographical region.

High non-use of contraception among tribal and non-tribal women in North-Eastern India: alarming but neglected.

Limited evidence exists about the contraception uptake in indigenous tribal groups of the north-eastern region of India. This study based on the National Family Health Survey (NFHS) IV (2015-2016) reports aimed to describe the pattern and factors associated with contraceptive non-use in the tribal women of the north-eastern part of India. The study was a cross-sectional analytical study based on secondary analysis of NFHS-IV data. All women in the age group of 15-49 years from the north-eastern part of India were included. Data were extracted and analysed using modified STATA-14 software. The association of socio-demographic and economic characteristics with contraceptive non-use was assessed using logistic regression. The inter-group differences of population characteristics for non-use contraceptives were assessed by modified Blinder-Oaxaca decomposition technique using 'Fairlie decomposition'. A total of 65,941 women were included, of whom 34,936 (52.9%) were tribal women. The proportion of contraceptive non-use was higher in tribal women. Tribal women with age at marriage above 30 years, Christian community, and women from Assam and Manipur state had higher odds of contraceptive non-use. The decomposition analysis showed that geographical variations, parity, and Christian religion contributed the most to contraceptive use disparity in the population. A huge gap was observed in contraceptive non-use among tribal and non-tribal women in the north-eastern part of India. The healthcare system must involve community representatives in designing context-specific community-based initiatives to increase the uptake of contraceptive use in these remote vulnerable communities.

Pregnancy and COVID—Complications and its Challenges: A Case Series from a Tertiary Care Center in the Northeastern Part of India

The objective was to describe the course of management of all the coronavirus disease 2019 (COVID-19)-positive pregnant women, admitted to a 150-bedded tertiary care center in Guwahati, Assam, from March 01, 2021, till June 15, 2021. We collected a case series of 13 COVID-19-positive pregnant women, mostly in their second and third trimesters, admitted to our center between March 01, 2021, and June 15, 2021. All of the cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection were confirmed by a positive result on real-time reverse transcriptase-polymerase chain reaction (RT-PCR) tests. We aimed to show the course of management and maternal outcomes in these cases. The Results show that among the 13 infected pregnant women, three presented with severe SARS-CoV-2 pneumonia and were treated in the intensive care unit (ICU) and the rest were treated in wards as the mild category and discharged successfully. Two among them required invasive mechanical ventilation (IMV), and one was managed on non-invasive ventilation (NIV). Of the two mechanically ventilated patients, one succumbed to the illness and the other patient was successfully weaned in 5 days and shifted out after 15 days of the ICU stay. The third patient was on NIV support for 7 days, weaned off to low-flow oxygen therapy via face mask/ nasal prongs, and shifted out after 17 days of the ICU stay. Data on pregnant women with coronavirus infection are scarce and contradictory as the effect of SARS-CoV-2 on pregnancy is not clear. It is highly important to systemically investigate the clinical characteristics and outcomes of pregnant women with COVID-19 to provide strong guidelines for prevention, treatment, and management.

MaxEnt modelling for predicting habitat suitability and future range of Black-breasted Parrotbill (Paradoxornis flavirostris Gould, 1836) in Northeast India

Abstract Habitat suitability models are powerful tools in predicting species distributions and assessing the potential impacts of environmental changes. In this article, a habitat suitability model was developed for Paradoxornis flavirostris, a threatened (Vulnerable) bird species found in the northeastern part of India, using remote sensing data and machine learning techniques. The occurrence records for P. flavirostris were considered from primary as well as multiple secondary sources like GBIF & eBird, and bioclimatic variables such as temperature, precipitation, and humidity were collected from www.worldclim.org. Then, MaxEnt algorithm was used to model the habitat suitability of P. flavirostris based on the collected data. Additionally, the model was also run to project the future range of P. flavirostris under different climate change scenarios. The model also predicts potentially suitable habitats for P. flavirostris outside of its current range, suggesting areas where the species may expand or contract its distribution in the future. This research provides valuable insights into the habitat suitability and potential range dynamics of P. flavirostris, and can inform conservation planning and management efforts for this threatened bird species.

Tracking Gross Primary Productivity Using Satellite Solar Induced Fluorescence: Insights Across Agricultural Ecosystems of India

AbstractAccurately estimating gross primary productivity (GPP) in heterogeneous cropping systems from satellite data poses a challenge. In this study, for the first time, we examined how satellite solar‐induced chlorophyll fluorescence (SIF) tracks GPP in India's diverse cropping system. A significant correlation (r = 0.70–0.90, p ≤ 0.05) at 0.0833° spatial resolution is observed between 8daily and monthly FLUXCOM GPP and Global Ozone Monitoring Experiment‐2 (GOME‐2) SIF. Compared to GOME‐2 SIF the finer resolution, TROPOspheric Monitoring Instrument (TROPOMI) SIF showed greater potential (r = 0.80–0.95, p ≤ 0.05) in estimating GPP and crop productivity, except for Southern and Northeastern parts of India. These regions of India have heterogeneous cropland and low crop area fraction as identified from normalized difference vegetation index (NDVI), near‐infrared reflectance of vegetation and local moran's index map of NDVI. This heterogeneity leads to differences in the timing of growth stages across the annual cycle, such that the SIF signal is characterized by low seasonal variability across the cycle, leading to low correlation between GPP and SIF. Further, in addition to physiological control the intra‐annual variability of GPP‐SIF relationship (GPP/SIF ratio) is influenced by temperature, radiation, and moisture availability during peak/late growing seasons. However, in the early growing season, it primarily relies on soil moisture. Our findings should help improve GPP estimation using SIF across the agricultural ecosystems of India.

Extraction of phenolic compounds from edible flowers (Phlogacanthus thyrsiflorus) using ultrasound‐microwave‐assisted extraction and its screening by HPLC

AbstractPhlogacanthus thyrsiflorus flowers have been consumed as a traditional delicacy in the north‐eastern region of India. The present investigation utilized the microwave‐assisted extraction (MAE) technique in conjunction with an ultrasound pretreatment (at 250 W for 15 min) to extract phenolic compounds from Phlogacanthus thyrsiflorus flowers. Here, independent factors for optimization of MAE were microwave power (300, 500, and 700 W) and extraction time (2, 4, and 6 min), and responses were total phenolic content (TPC), total flavonoid content (TFC) and DPPH (2,2‐dipheny‐1‐picrylhydrazyl) activity. For the experimental design, a Response surface methodology and a central composite design were followed. The optimum MAE condition was found at microwave power 700 W for 5 min resulting 30.204 mg GAE/g TPC, 81.26% DPPH and 22.50 mg QAE/g of TFC. The extraction of phenolic compounds was significantly impacted by both the microwave power and the extraction time. The high‐performance liquid chromatography (HPLC) analysis detected various phenolic compounds in both conventional and MAE extracts. However, compared to conventional extract, the majority of the identified phenolic compounds were found to be higher in quantities in MAE extract. These results highlighted that MAE‐optimized flower extract could be beneficial as a functional ingredient for food product development.Practical applicationsPhlogacanthus thyrsiflorus is a highly nutritious flower with medicinal properties. Though traditionally edible flowers have been consumed in the northeastern part of India but people are still neophobic and there is scanty awareness available regarding the benefits of consuming edible flowers. This scientific justification regarding the advantages of edible flowers makes them appealing for future novel use in food technology and also for further scientific study. High perishability of flowers makes them limited for market viability and extraction of its phenolic compounds is one of the novel solutions to utilize the flowers before spoilage. Also, using ultrasound as a pretreatment could enhance the efficiency of microwave‐assisted extraction techniques for a higher yield of phenolic compounds. Microwave‐assisted extraction technique as its novel and was proven an easy successful extraction technique on this flower. Also, the study of phenolic compounds through HPLC provides important information regarding the presence of various phenolic compounds in the Phlogacanthus thyrsiflorus flower. This research can be supportive of both food technology and the medicinal industry.

Genome sequencing and assembly of Indian golden silkmoth, Antheraea assamensis Helfer (Saturniidae, Lepidoptera)

Muga silkworm (Antheraea assamensis), one of the economically important wild silkmoths, is unique among saturniid silkmoths. It is confined to the North-eastern part of India. Muga silk has the highest value among the other silks. Unlike other silkmoths, A. assamensis has a low chromosome number (n = 15), and ZZ/ZO sex chromosome system. Here, we report the first high-quality draft genome of A. assamensis, assembled by employing the Illumina and PacBio sequencing platforms. The assembled genome of A. assamensis is 501.18 Mb long, with 2697 scaffolds and an N50 of 683.23 Kb. The genome encompasses 18,385 protein-coding genes, 86.29% of which were functionally annotated. Phylogenetic analysis of A. assamensis revealed its divergence from other Antheraea species approximately 28.7 million years ago. Moreover, an investigation into detoxification-related gene families, CYP450, GST, and ABC-transporter, revealed a significant expansion in A. assamensis as compared to the Bombyx mori. This expansion is comparable to Spodoptera litura, suggesting adaptive responses linked to the polyphagous behavior observed in these insects. This study provides valuable insights into the molecular basis of evolutionary divergence and adaptations in muga silkmoth. The genome assembly reported in this study will significantly help in the functional genomics studies on A. assamensis and other Antheraea species along with comparative genomics analyses of Bombycoidea insects.

Long‐term assessment of ERA5 reanalysis rainfall for lightning events over India observed by Tropical Rainfall Measurement Mission Lightning Imaging Sensor

AbstractThe ability of numerical weather prediction models to accurately predict extreme weather events, such as thunderstorms marked by heavy rainfall and lightning activities, has consistently been of great importance for human life. The objective of this study is to assess the long‐term reliability of the European Centre for Medium‐Range Weather Forecasts Reanalysis version 5 (ERA5) rainfall in comparison to the Indian gauge‐adjusted Global Satellite Mapping of Precipitation (GSMaP_ISRO) rainfall at the time of lightning flashes measured by the Lightning Imaging Sensor (LIS) onboard the Tropical Rainfall Measuring Mission satellite over the Indian region during the years 2001–2014. This analysis will provide valuable insights into the intricate relationship between lightning flashes and precipitation under various terrain conditions (low, mid, or high), across oceanic regions (Bay of Bengal, Arabian Sea), and during different monsoon phases (normal, active, or deficit). According to a prolonged examination of LIS data, April–June accounts for ~50% of the total flashes, with the largest number of flashes occurring over the Himalayan and the northeastern part of India. According to hourly GSMaP_ISRO rainfall, the most substantial lightning‐associated rainfall happens an hour prior to lightning flash (T − 1) and within three hours after (T + 3), indicating a robust correlation between heavy rainfall and lightning activity during this time frame. The rainfall in the ERA5 reanalysis misses the intensity as well as duration of the peak rainfall at the time of lightning flashes. Furthermore, the ERA5 reanalysis rainfall depicts under (over)‐estimation of rainfall in plain (orographic) regions. The underestimation of ERA5 rainfall is very pronounced over the Indian Ocean and Bay of Bengal regions, mainly between flash time (T) to two hours after the flash time (T + 2). The results indicate that there is a requirement for additional enhancements in the ERA5 reanalysis rainfall for lightning occurrences.

Internalized Stigma among Persons with Schizophrenia: A Study from Tertiary Care Center in the Northeastern Part of India

Abstract Background: Stigma relating to mental illness has mostly been studied in communities and families. Less research has been conducted in India to understand the current subjective experience of persons with mental illness in the tertiary care hospital setting in India. Aim and Objectives: This study aimed to assess the extent of internalized stigma among persons and to see the association between self-stigma, self-esteem, insight, and adherence. Methodology: The study used a cross-sectional design. The present study was conducted in the Outpatient Department of LGB Regional Institute of Mental Health, Tezpur, Assam. For the present study, 200 persons with schizophrenia were selected. Participants of this study were persons with a clinical diagnosis of schizophrenia according to the International Classification of Diseases-10 Diagnostic Criteria for Research. Sociodemographic and clinical data sheet, Brief Psychiatric Rating Scale, the Internalized Stigma of Mental Illness Scale, Morisky Adherence Scale, and Rosenberg Self-Esteem Scale were administered. The collected data were analyzed using descriptive and inferential statistics in Statistical Package for Social Science (SPSS) 21 version. Results: The findings show that 45% of the participants were having moderate internalized stigma and 21% of the participants were having severe internalized stigma. Self-Esteem Scale (B = −341, t = −2.940, P = 005), medication adherence (B = −701, t = −9.832, P = 000), and insight (B = −711, t = −6.496, P = 000) contributed significantly to the prediction of internalized stigma among persons with schizophrenia (F [3,63] =58.712, P = 000) accounting for 85.8% variance. Conclusion: The findings confirm that self-esteem, medication adherence, and insight contributed significantly to the prediction of internalized stigma among persons with schizophrenia.

Recurrence analysis of meteorological data from climate zones in India.

We present a study on the spatiotemporal pattern underlying the climate dynamics in various locations spread over India, including the Himalayan region, coastal region, and central and northeastern parts of India. We try to capture the variations in the complexity of their dynamics derived from temperature and relative humidity data from 1948 to 2022. By estimating the recurrence-based measures from the reconstructed phase space dynamics using a sliding window analysis on the data sets, we study the climate variability in different spatial locations. The study brings out the variations in the complexity of the underlying dynamics as well as their heterogeneity across the locations in India. We find almost all locations indicate shifts to more irregular and stochastic dynamics for temperature data around 1972-79 and shifts back to more regular dynamics beyond 2000. These patterns correlate with reported shifts in the climate and Indian Summer Monsoon related to strong and moderate El Niño-Southern Oscillation events and confirm their associated regional variability.

A checklist of wild mushroom diversity in Mizoram, India

The northeastern part of India is one of the biodiversity hotspots having a wide variety of flora and fauna. High humidity during monsoon provides ideal conditions for the growth of diverse group of macrofungi. Mizoram is one of the northeastern states of India which has a large number of edible and non-edible mushroom species. Wild edible mushrooms are an important food source for rural communities of Mizoram and provide additional income to the households if sold in regional markets. The key objective of this study was to explore the macrofungal diversity, and its richness in Mizoram with the aim of preparing a checklist along with the present geographical distribution of the important wild edible mushrooms. The macrofungal survey was undertaken during 2017–2020 in 24 different sites in Mizoram. A total of 152 (54 edible and 98 inedible) mushroom species have been documented belonging to 85 genera, 54 families, and 19 orders. Habitat-wise distribution of macrofungi revealed that maximum species were found on soil (61), followed by associated with roots (36), dead wood (30), living trees (22), and associated with termite mound (three). From a morphological point of view, the wild mushrooms have been divided into gilled fungi (95), boletes (18), polypores (17), coral fungi (10), chanterelles (3), puffballs (3), jelly fungi (3), stinkhorns (2), and cup fungi (1). This documentation of wild mushrooms of Mizoram will be a reference database for future.

In vitro bioactivities and gastrointestinal simulation validate ethnomedicinal efficacy of five fermented kodo-based Himalayan traditional drinks and bioaccessibility of bioactive components

Tongba, chhyang, nigar and raksi are popular traditional drinks served in Nepal, northern and north eastern part of India and Tibetan plateau which are claimed as medicinal and considered as elements of high altitude ethnopharmacology. In this research, kodo (finger millet) based traditional beverages such as tongba, chhyang, nigar and raksi samples, collected from Singalila ridge of the Himalayas, were analysed through various qualitative and quantitative biochemical parameters. Total phenolic content (gallic acid equivalent) was estimated in a varied range from 936.26 ± 6.87 µg/mL (nigar) to 96.36 ± 1.22 µg/mL (chimphing raksi) while highest free fatty acid was measured in khokim raksi (2.11%). Antioxidant activity was evaluated using in vitro assays (DPPH assay, iodometric assay and in vitro anti-lipid peroxidation assay); antibacterial assay was conducted using well diffusion method. Tongba was found to be the most potential sample in antioxidant assays with a DPPH scavenging value of 85.31 ± 1.54% while nigar was the sample with most promising antibacterial activity. Furthermore, special emphasis was given on GC-MS based metabolite profiling and metabolomic elucidation. Responsible candidates detected by GC-MS analysis were discussed to correlate results of preliminary biochemical screenings and in vitro bioactivities. In vitro gastrointestinal digestion was carried out to figure out bioaccessibility of the bioactive groups of compounds in simulated human GI tract where DPPH assay, total phenol content and lipid composition (acid value) were considered as parameters. Most of the bioavailable bioactive antioxidants and phenolics were estimated to be decreased in the gastric phase reflecting the highest rate of digestion in the stomach while breakdown of lipid composition was dominated by the intestinal phase. Overall results suggest that antioxidative phenolics and fatty acids from these beverages possess bioactivities in their bioavailable form which may be associated to their ethnomedicinal properties.Graphical
