Abstract: Digital twin (DT) is the latest technology, which helps
in generation of exact digital replica of the physical
system. In this work, an in-house DT of a thermovacuum chamber and payload is developed. This research paper covers the development and implementation
of an in-house cross-platform software application, a
mobile AR app, and a Microsoft HoloLens 2 application, which provides real-time sensor data with voice
control. The objective of this research is to study the
potential of DT technology in real time monitoring of
testing of payloads in thermovac system. Results
demonstrate that the developed software applications
provide a comprehensive 1 : 1 scale 3D visualization of
the chamber along with essential sensor parameters for
users to monitor the chamber and payload status, leading to a more effective decision making

Abstract: A dam is a structure that aids the growth of a country
in terms of infrastructure development. For such a
magnificent structure design, its stability is vital. The
Cheruthoni dam in Kerala, India (gravity dam) was selected for the present study. The reservoir-full condition,
hydrostatic pressure, uplift pressure and earthquake
pressure forces were chosen for failure analysis by considering seismic coefficient and downstream slope angle
as critical parameters. The analysis was done regarding
stress and displacement, and the results were interpreted using RS2 software. The results revealed that
the downstream slope angle is more critical than the
seismic coefficient

Subject: Sustaining long-term agricultural exports from India
Keywords: Agricultural exports, comparative advantage, COVID-19 pandemic, rejections, trend.
Abstract: In this study, we analysed the trend, composition and
dynamics of India’s comparative advantage in agricultural exports from 2001 to 2021 using data from the
INTRACEN database for seven agricultural commodities, namely rice, crustaceans, bovine meat, cotton, pepper, cane sugar and tea. The contribution of agricultural
exports to the agricultural gross value added (GVA)
has increased over time. The country has the highest
comparative advantage in rice, followed by pepper and
tea, while crustaceans and bovine meat show a lower
comparative advantage. The COVID-19 pandemic disrupted the supply chains, causing a decline in exports
of bovine meat and tea. The study also probed the reasons
behind export rejections in major importing markets.
Pesticide residues, microbial infections and consignment management emerge as the major reasons for
export rejection. Effective value-chain management is
critical for the quality and safety compliances of the
commodities.

Subject: Detection of Alternaria blight disease severity in mustard crops using ground-based hyperspectral remote sensing
Keywords: Alternaria blight, disease severity, mustard, hyperspectral, remote sensing, surface reflectance.
Abstract: Alternaria blight is a destructive disease of mustard
crops that causes significant economic loss and usually
warrants extensive pesticide application. Characterization and estimation of pest severity for better management is the need of the hour to increase the scope of
advisories to the farmers. In this study, statistical approaches like multiple stepwise linear regression, principal component regression and partial least square
regression have been employed to detect the disease
severity of Alternaria blight in mustard leaves using
hyperspectral reflectance data. The predicted values of
diseased leaves in all the regression models were significantly reduced vis-à-vis healthy mustard leaves. The
results of this study indicate that it is possible to detect
the disease severity of Alternaria blight in mustard
crops using hyperspectral reflectance data.

Subject: Genetic and multivariate analysis of processing and yield traits in sweet potato for varied end-uses
Keywords: Heritability, processing, sweet potato, variability, yield traits
Abstract: The present study aims to assess the genetic and multivariate component analysis of processing traits, yield
traits, weevil resistance and other tuber traits in sweet
potatoes based on the evaluation of 12 genotypes, including checks for yield and processing. Significant variability for tuber physical, processing and vine traits was
observed. Nearly 75% of the genotypes had dry matter
content (>30%), 50% had starch content (>20%), and
none was resistant to sweet potato weevils. High genotypic and phenotypic variation, heritability and genetic
advance were observed for tuber yield, tuber girth, total sugar and weight. Among the 13 phenotypic traits
used in the present study, multivariate analysis identified only eight, contributing to 83.67% of the variation.
UPGMA clustering yielded two major clusters and five
sub-clusters. S27, Palakkad local, Trivandrum local,
Sree Arun, S346, S27, Indira Madhur, EC 321693 and
S444 were found suitable for processing. These genotypes can serve as breeding material for developing high yielding varieties, thereby promoting the industrial utilization of sweet potatoes.

Abstract: The present study focuses on the synthesis of organic
fluorescent and thermally stable polyesters using the striazine frame. Coumarin and benzilic acid have been
utilized as bulky pendant groups. It has been established
that these two groups are mainly accountable for fluorescence and enhancing the stability of polyesters. The synthesized polyesters were characterized using a plethora
of techniques. The structural elucidation was carried
out using infrared spectroscopy and nuclear magnetic
resonance spectroscopy. The stability of the polyesters
for 10% and 50% weight loss was assessed using thermogravimetric analysis. The solubility behaviour was observed for both polar and nonpolar solvents. The useful
traits of these polyesters, such as fluorescence and enhanced thermal stability, make them important.

Subject: Meteorological conditions associated with extremely heavy rainfall over some Indian states in July 2022
Keywords: Extremely heavy rainfall, floods, meteorological analysis, southwest monsoon
Abstract: The second week of July 2022 witnessed persistent
heavy rainfall episodes over the Indian states of Gujarat,
Maharashtra, Telangana and coastal Karnataka. According to media reports, this led to localized flooding over
these regions. Rainfall data from the India Meteorological Department revealed that heavy to very heavy
rainfall with extremely heavy rainfall at isolated places
had occurred over Gujarat region for five days; over
Saurashtra and Kutch, Konkan and Goa, Telangana
and coastal Karnataka for three days each, and over
Madhya Maharashtra and Vidarbha for two days each
during 7–13 July 2022. The present study aimed to
evaluate the meteorological parameters, associated synoptic systems, and dynamic and thermodynamic parameters responsible for such persistent heavy rainfall
episodes over these regions during the second week of
July. The following meteorological conditions may have
resulted in persistent heavy-rainfall episodes: (i) Location of monsoon trough (south of the normal position).
(ii) An offshore trough along the west coast of India
during the study period. (iii) An east–west shear zone/
trough in the lower/mid tropospheric levels across the
northern parts of peninsular India and southward tilt.
(iv) Convergence of strong monsoon westerlies along
the west coast of India. (v) Favourable relative vorticity
up to middle tropospheric levels. (vi) Favourable lowlevel convergence and upper-level divergence. Favourable air temperature and vertical velocity (omega) at
different tropospheric levels. (vii) Favourable relative
humidity profile at the lower tropospheric levels

Subject: Food safety knowledge, attitude and practices related to refrigeration safety
Keywords: Diseases and risk factors, food-handling practices, food safety, refrigeration, storage temperature
Abstract: It is crucial that we have access to nutritious food in
order to support life and promote good health. Unsafe
food that contains harmful microbes, viruses, parasites, or chemicals causes ailments ranging from diarrhoea to cancer. It is well-recognized that maintaining
food safety requires keeping food in the refrigerator at
a proper temperature. It is also crucial to regulate and
maintain the storage temperature, which will vary
based on the type of food stored. The main aim of this
study is to assess the knowledge, attitudes and practices
of consumers towards food safety. Gender, age, educational level, number of children and frequency of food
preparation are the factors that affect an individual’s
knowledge and attitude about food safety. It is essential
to plan and conduct training programmes on food safety
and appropriate handling practices for different foods
to prevent foodborne diseases and associated risk factors.

Keywords: Article processing charges, commercial publishers, gold open access, scholarly output, subject category
Abstract: Article processing charges (APCs) ensure the financial viability of open access (OA) scholarly journals.
The present study analyses the number of gold OA articles published in the Web of Science (WoS)-
indexed journals by Indian researchers during 2020, including subject categories that account for
the highest APC in India. Besides, it evaluates the amount of APC expenditure incurred in India. The
findings of this study reveal that Indian researchers published 26,127 gold OA articles across all
subjects in WoS-indexed journals in 2020. Researchers in the field of health and medical sciences
paid the highest APC, amounting to USD 7 million, followed by life and earth sciences (USD 6.9
million), multidisciplinary (USD 4.9 million), and chemistry and materials science (USD 4.8 million). The study also reveals that Indian researchers paid an estimated 17 million USD as APC in
2020. Furthermore, 81% of APCs went to commercial publishers, viz. MDPI, Springer–Nature,
Elsevier and Frontier Media. As there is a growing number of OA publications from India, we suggest having a central and state-level single-window option for funding in OA journals and backing
the Plan S initiative for OA publishing in India.

Abstract: The genus Drosophila is an interesting biological model which shows extensive diversity at the level
of species. About 50 years ago, Bock and Wheeler described a new species of Drosophila, D. pallidosa just on the basis of sexual isolation and differences in sex comb teeth number. However, there
is similarity in male genitalia and absence of post mating reproductive isolation and it is considered
sibling to D. ananassae, which is a domestic and cosmopolitan species. On the other hand, D. pallidosa is endemic to certain islands such as South Pacific Island of Samoa and Fijii where they are
sympatric and remain reproductively isolated by sexual isolation.
In these two sibling species, results of various investigations have been reported pertaining to taxonomic status, morphometric traits, metaphase karyotypes, etc. show similarities and differences
which is basis of suggestion that D. pallidosa is in statu nascendi. However, its description as a new
species fits well with the biological species concept and it provides interesting material for future
studies in the area of speciation genetics.

Abstract: Evidence of fossil predators enables us to
infer the importance and evolution of predation, predator ethology and prey defence
mechanisms in deep time1
. Foraminifera, an
ubiquitous component of the marine seafloor community with a high preservation
potential, are often subjected to predation
.
However, bioerosion traces do not necessarily reflect predation traces because live
foraminiferans may bear parasite feeding
traces, and dead foraminiferal tests may be
subjected to boring by protoplasm-scavenging taxa or endoliths
. Here, we report
octopodiform (terminology after VillegasMartín et al.
4
) drill holes on the middle
Eocene larger foraminiferan Nummulites
obtusus (Sowerby5
) from Kutch, western
India. We have collected 35 N. obtusus
Form B specimens bearing the octopodiform
drill holes. These drilled foraminiferans were collected from the ‘obtusus
bed’ of the Harudi Formation (middle Eocene) exposed along the flanks of the Rato
river, north of the Harudi (23°30′30″,
68°41′10″) village in Kutch, Gujarat6,7.
Collected specimens are housed in the Micropalaeontology Laboratory of Calcutta
University under the collective number

Abstract: A chain of unprecedented floods and landslides beginning in early July of 2023 in
the Western Himalaya and its adjoining
plains of Punjab, Haryana and western Uttar
Pradesh, India, shook the entire nation due
to large-scale destruction in terms of human
lives, properties, landscape and environment.
It began with the extreme rain episodes
across the width of the Himalaya, leading to
high-velocity water flowing from the steep
hill slopes along low-order streams into the
main rivers. In the stepwise process, it initially filled the river channels and was followed by extensive flooding in the alluvial
plains, inundating extensive areas of Punjab
and Haryana along River Ghagghar and
Delhi–Uttar Pradesh along River Yamuna.
In Himachal and Uttarakhand, rainfall also
triggered a sequence of landslides of different scales in the urban areas and roadsides.
These disasters have annihilated almost all
our landslide-preventing measures and
flood-taming capacity and exposed the
fragility and hollowness of our habitational
planning, especially in the hilly regions

Keywords: Dire impact of climate change, marine ecosystems
Abstract: It is widely acknowledged globally that climate change is
an undeniable reality caused by human intervention, as
confirmed by the Intergovernmental Panel on Climate
Change (IPCC) Assessment Reports. The concentration of
greenhouse gases in the atmosphere is steadily rising,
leading to an increase in the planet’s average temperature.
Climate change has also brought about several other consequences, such as severe weather patterns, rising sea levels,
deforestation, agricultural challenges, waste management
concerns, and air pollution, among others. When we talk
about the environmental impact of climate change, issues
are both global and regional in nature. However, global
concerns such as rising temperatures, sea levels, and severe
weather events require the collective efforts of the worldwide community.

Subject: RNA sequencing-based identification of candidate hypersensitive transcripts in Perna viridis
Keywords: Allergen, hypersensitive transcripts, Perna viridis, RNA sequencing, unigenes.
Abstract: The Asian Green Lipped mussel, Perna viridis one of the
widely distributed bivalves act as a source of low cost
protein providing nutritious meal to the coastal population in the form of well balanced amino acids and
micronutrients. The immune system produces antibodies to certain class of proteins present in shellfish meat
thereby causing hypersensitive reactions in the body.
The next generation integrated transcriptome sequencing
approach identifies all the potential allergenic proteins
expressed in an animal very effectively. The present
study describes the transcriptome of P. viridis based on
the sequence data generated using five tissues. Transcriptome level candidate allergens and epitopes were
observed and identified that might play a role in hypersensitive reaction to shellfish proteins including certain
novel candidate allergens like Ran protein and a filamin A like protein. The existence of epitope hotspots in
an important protein, arginine kinase was also observed
and the unigenes identified would be a valuable resource for conduct of functional studies.
