Subject: Synthesis and characterization of various organic fluorescent and thermally stable polyesters with s-triazine frame and bulky side chain
Keywords: Bulky pendant groups, fluorescence, polyesters, thermal stability, viscosity
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.

Subject: Publications in gold open access and article processing charge expenditure: evidence from Indian scholarly output
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.

Keywords: Biological species concept, Drosophila ananassae, Drosophila pallidosa, genetic diversity, speciation genetics.
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
CU/RR/35.

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

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.

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.

Keywords: Aquifer systems, artificial recharge, groundwater, transformative impact, water conservation
Abstract: Groundwater contributes to 9% of India’s GDP; 64%
of irrigation, 85% of rural water supply and over 50%
of urban water demand. Over the last decade, 54% of
India’s shallow wells became defunct due to declining
groundwater levels and thus deep wells have been constructed. This shift to deeper wells has led to more
groundwater withdrawal than natural recharge resulting
in over-extraction. Most of States and Central Government agencies focus on groundwater recharge and
conservation to address sustainability through schemes
like Jal Shakti Abhiyan and MGNREGA. These interventions between 2017 and 2020 led to a notable 12.46 bcm
increase in groundwater resources in hard-rock aquifers. This study’s findings would assist policymakers and
administrators in evaluating the effectiveness of schemes
for different aquifer, and drawing their attention to
suggests design changes for more effective recharge of
groundwater.

Abstract: In the Anthropocene era, understanding the impact of
climate change on niche shift, species distribution, and
habitat change is increasingly important for the conservation of biodiversity. In this respect, species distribution
models have been considered an important tool over
the last decade. The present study illustrates distributional change, niche dynamics and climatic shifts of Saraca asoca (Roxb.) De Wilde in India, a proven medicinal
plant and a listed threatened species by IUCN, under
different climate change scenarios using MaxEnt. The
robustness of the model was satisfactory (AUC = 0.936),
indicating a good fit. There could be a significant gain
in suitable habitat between the present and future scenarios, ranging from a minimum of 52,275.17 km2
(RCP 2.6) to a maximum of 95,994.62 km2 (RCP 4.5). In
the future, the suitable habitat range would shift towards
colder regions of India, where cultivation of S. asoca
could be taken up, thus enabling effective management
of the natural habitat and population of the species.
This study will help understand the effects of climate
change on S. asoca and its implications for conservation
of the species

Subject: Factors hindering the adoption of innovations in the arid agro-ecosystems of India
Keywords: Adoption of innovations, agricultural technologies, arid agro-ecosystems, rural development.
Abstract: This study deals with the factors hindering the adoption
of innovations in the arid agro-ecosystems of India.
Adoption of agricultural technologies helps increase
agricultural output, which can impact poverty levels
and environmental degradation. The present study was
conducted in Rajasthan, India, to identify the technology
adoption of agricultural households and various socioeconomic and socio-personal factors affecting the same.
Among several coping strategies for climate vulnerability,
other than a shift towards rainfed crops, reducing the
number of irrigations, deepening existing wells and advancing or delaying irrigation were common in the arid
ecosystems. Some important policy measures have been
drawn from this study. First, the sustainable development
of groundwater resources, particularly in the low-productive eastern region, would go a long way in improving
agricultural productivity in the country. Agricultural
productivity can also be improved by increasing fertilizer use. Second, it proves cost-reducing technologies
and creates awareness of better resource-saving options
for better returns. Finally, advisory services and the
availability of extension personnel are important in rural
development.

Subject: Tectonic restoration of the Achankovil Suture Zone, South India: correlation with Ranotsara Shear Zone, Madagascar
Keywords: Aeromagnetic data, lithological units, magnetic anomaly, suture zones, tectonic restoration.
Abstract: The total magnetic intensity (TMI) image of the southernmost part of the Indian peninsular shield exhibits a
conspicuous NW–SE trending mega lineament of 200 km,
associated with Achankovil Suture Zone (AKSZ) across
the Southern Granulite Terrain (SGT) that evolved
during East African Orogeny. This crustal scale anomaly
of 200 nT amplitude, is significant to understand the
regional tectonics and the possible linkage between
AKSZ and Ranotsara Shear Zone (RSZ) of Madagascar.
The structural trends are inferred from magnetic data
surrounding AKSZ and RSZ to reconstruct the Gondwana fragments of the SGT and south Madagascar.
The aeromagnetic images of conjugate rifted fragments
of this part of India and Madagascar are connected
well on both sides: the Madurai block with Antananarivo
domain and Trivandrum block with Anosyan domain,
north and south of AKSZ–RSZ respectively. Magnetic
modelling across AKSZ reveals a hidden subsurface
basic body suggesting a deep geofracture. We infer the
sequence of tectonic development of the AKSZ as: (i) the
subduction–accretion process in amalgamation of continental fragments to form Gondwana supercontinent
during the Late Neoproterozoic and (ii) Pan-African
exhumation of anomalous sub-crustal material.

Subject: Preliminary insights into the impact between photovoltaic installations and climate change
Keywords: Ambient temperature, climate change, failure probability, performance and service life, solar photovoltaics
Abstract: Solar photovoltaic (PV) installations are growing exponentially globally, with a rising fraction of solar PVs in
the renewable energy mix. Climate change is also expected to influence PV installations worldwide. Understanding the climate change impact on PV installations
has been the scope of many recent studies. This article
reviews recent studies on climate change impacts on
PV installations based on the present scenario, and examines the effect of rising temperatures on the performance
and service life of PV installations. On the contrary,
PV installations may also cause an increase in the local
ambient temperature. The impact of PV installations
on the local and global climate is yet to be established.
Comprehensive studies need to be undertaken to examine
the impact between climate change and the performance
of PV installations.
