Subject: Geospatial technology in groundwater recharge potential assessment using multi-criteria decision-making approach
Keywords: Geospatial technology, groundwater recharge, multi-criteria analysis, rainwater harvesting, water scarcity.
Abstract: Many regions in India and worldwide are currently
grappling with or have experienced water crises, primarily due to frequent droughts, expanding agricultural land, and excessive groundwater abstraction. The
primary objective of present study is to map groundwater recharge (GWR) potential in hard rock-dominated terrain. The approach involves an ensemble of
techniques, combining an integrated analytic hierarchy
process with the geographic information system. Various hydrogeological and groundwater-controlling factors, including geology, slope, geomorphology, depth to
water level, soil types, normalized difference vegetation index, land use/land cover and drainage density
were mapped and assessed using satellite data and field
verification. The methodology was applied in the
Chhindwara region in the southern part of Madhya
Pradesh, India, where the geological composition is predominantly hard rocks. The outcomes of this study can
be utilized for GWR potential mapping, land-use planning, rainwater harvesting and formulating groundwater development plans.

Keywords: Aproaerema modicella, Aproaerema simplexella, DNA barcoding, leguminous crops, morphological identification
Abstract: The groundnut leaf miner (GLM), Aproaerema modicella
Deventer (Lepidoptera: Gelechiidae), is a consequential pest of groundnut and other leguminous crops,
which causes yield loss of up to 30–60% in groundnut in
India. Nevertheless, some scientific studies have reported
the occurrence of soybean moth, Aproaerema simplexella Walker attacking groundnut in India. The present study was conducted to assess the leaf miner
species destroying groundnut in different regions of
Tamil Nadu, India. Correctly identifying an insect species based on morphological and molecular techniques
may pave the way for formulating accurate insect pest
management strategies. Studies on the morphological
characters of GLM confirmed that the species found in
different districts of Tamil Nadu is A. modicella. However,
BLAST search of GLM sequences indicated 100% similarity with A. simplexella. Since morphological characters of larva, pupa, adult, and male genitalia indicated
the GLM species available in Tamil Nadu, as A. modicella, the sequences acquired from the present study
have been submitted as the first entry in the NCBI database for species-level representation of A. modicella.

Subject: Impact of prescribed fire on nitrogen mineralization in three different ecosystems of the north-western Himalaya: an insurance to wildfire-prone ecosystems
Keywords: Ammonification, chir pine forest, grassland, nitrogen mineralization, prescribed fire, scrubland
Abstract: To understand the dynamics of nitrogen pools in response to prescribed fire, a study was carried out with
four land uses, viz. chir pine forest (Pinus roxburghii),
grassland, scrubland and non-fire site in chir pine
(control) at three soil depths (0–5, 5–10 and 10–15 cm)
for a period of one year. The results revealed that ammonification rate increased initially for few months postfire up to the rainy season and then showed a declining
trend in all the burnt land uses, and decreased with increasing soil depth. The nitrification rate was almost
the same as pre-fire levels in the initial few months after
fire, and then started increasing from August onwards
till the end of the study period. Post-fire, the net nitrogen mineralization was found higher in all the burnt
land uses over control. Prescribed fire accelerates the
rate of net N mineralization which contributes to ecosystem productivity.

Keywords: Burn scar extraction, change vector analysis, forest fire, spectral indices, weighted fusion.
Abstract: The present study was conducted in the tropical dry
deciduous forests of Vidarbha region, Maharashtra,
India. Burn scar discrimination capabilities of seven
widely used spectral indices (SIs) such as burn area index
(BAI), burned area index modified-LSWIR (BAIML),
burned area index modified-sSWIR (BAIMs), normalized burn ratio (NBR), normalized difference vegetation index (NDVI), normalized difference moisture
index (NDMI), modified soil-adjusted vegetation index
(MSAVI) and their weighted fusion were examined in
a multi-temporal domain. This study generated different images during fire season using individual SIs,
change vector analysis and weighted fusion normalized
difference image technique. Comparative analysis was
performed between these approaches for burn scar
discrimination with M statistics, burned and unburned
class distribution and evaluation of confusion matrix. The
study demonstrates that the weighted fusion of BAI,
MSAVI and BAIMs can more accurately discriminate
burn scars with good overall accuracy (86.61%)

Subject: Dynamic performance of vibration absorbers for low-frequency vibration isolation systems
Keywords: Deflection, fatigue, natural frequency, stiffness, stress, vibration attenuation
Abstract: The present study introduces a novel mass-spring system
utilizing a well-designed polyurethane pad vibration isolator conceptually designed as a floating slab track
structure. The floating slab track is considered one of
the most efficient countermeasures for attenuating the
vibration impacts of underground high-speed railways.
The dynamic performance of the polyurethane slab track
structure was studied and compared with the steelspring floating slab track using a conventional mathematical approach based on the principle of influence
lines. The study examines vibration isolation performance under dynamic vehicle loads at speeds ranging
from 180 to 300 kmph. Results indicate a significant
reduction in slab dynamic responses with increasing
speed. Both systems demonstrate excellent vibrationdamping ability, with the steel mass-spring system being
approximately 18% more efficient in vibration reduction
than the polyurethane mass-spring system

Keywords: Hyperspectral imaging, lunar exploration mission, optimum estimation, retrieval algorithm, spectral emissivity, surface temperature.
Abstract: The Imaging InfraRed Spectrometer (IIRS) on board
Chandrayaan-2 has been providing high spatial and
spectral resolution observations of the lunar surface in
256 spectral bands (0.7–5 µm) since September 2019. It
is primarily intended for mineral mapping and identifying hydration features on the lunar surface using reflectance spectra in the range of 0.7–3.2 µm. Here, we
have used the IIRS observations in the 3–5 µm range to
retrieve daytime lunar surface temperature and spectral
emissivity using an optimal estimation theory-based retrieval algorithm. The surface temperature is retrieved at
every pixel, while spectral emissivity is retrieved at
every third pixel of the hyperspectral image. The mean
uncertainty of the retrieved spectral emissivity varies
from 0.04 to 0.08, while for surface temperature, it is
about 3.5 K. The retrieved spectral emissivity is found
to be in close agreement with the emissivity of the
Apollo-16 return soil samples.

Abstract: India’s third Moon mission Chandrayaan-3, has successfully deployed a lander and a rover at a high-latitude
location on the Moon to conduct in situ scientific studies
that will potentially improve our understanding on the
primary crust formation and subsequent modification
processes. While the primary landing site (PLS) was
situated at 69.367621°S lat., 32.348126°E long., an alternate landing site (ALS) was selected at nearly the same
latitude but ∼450 km west of PLS, as a contingency.
We carried out a detailed study of the geomorphology,
composition and temperature characteristics of ALS
using the best-ever high-resolution digital elevation models (DEMs) and ortho-images, and datasets obtained
from Chandrayaan-1 and the on-going Lunar Reconnaissance Orbiter along with a well-established thermophysical model. Results indicate that like PLS, ALS is
also an interesting site for carrying out in situ scientific
studies from any future lunar-landing mission.

Abstract: Milk has been considered a completely natural food
with an excellent nutrient profile without any antinutrients. Various health issues like lactose intolerance,
cow milk protein allergy and high cholesterol/fat are
some of the possible reasons for the increased consumption of plant-based milk analogues. Several new plant based beverages are being marketed as milk alternatives.
In this study, we compare the nutritional contents of
plant-based beverages (PBBs) and bovine milk to determine whether the nutritious content of the fortified
PBBs is comparable to bovine milk. The detailed nutritional breakdown and associated adverse effects of
consuming these plant-based beverages have been covered in detail, which might aid customers in making an
educated choice. Ultimately, the awareness of consumers
will decide the priority of food they want to consume.

Abstract: The commentary discusses the landmark FDA Modernization Act 2.0, which eliminates the mandatory use of
animal testing in obtaining licenses for certain drugs. The Valley of Death in drug development, marked by high
clinical trial failure rates, is attributed to the lack of target similarity between animal and human models. The
commentary emphasizes the need for a paradigm shift, encouraging the adoption of alternative testing methods,
including advanced in-vitro and in-silico approaches. The FDA’s decision signals a pivotal moment in drug development history, urging the industry to embrace a holistic and progressive approach that prioritizes innovative,
ethical, and sustainable methodologies.

about its sustainable management. Each year, a relevant
theme is chosen by UN-Water (https://www.unwater.org);
the theme for 2024 is ‘Water for Peace’.
The availability of water varies by place and time. Water
is most beneficial when good quality water is present, at
various times, in nearly the same quantity as needed. However, the distribution of water resources across the globe
and the variability in their occurrence rarely matches the
demands. Infrastructure is constructed and managed to
match water availability with demands, subject to various
