Subject: Finkoella: a sack-like Ediacaran soft-bodied fossil from the Marwar Supergroup, western Rajasthan, India
Keywords: Ediacaran, Finkoella, Marwar Supergroup, sack-like bodied fossil, tunicate organisms, western Rajasthan.
Abstract: The present study reports the well-preserved Ediacaran sack-like soft-bodied fossils assigned as Finkoella
ukrainica and Finkoella oblonga from the Sonia Formation of the Jodhpur Group, Marwar Supergroup,
western Rajasthan, India. The F. ukrainica is found in
elliptical, ovate-shaped and sometimes oblong or cucumber-shaped forms with a distinct short neck, and a
small circular protrusion or depression may be present
on the organism. F. oblonga is elongated, ovate to cucumber-shaped fossil specimen with poorly preserved six
longitudinal low grooves and ridges arranged parallel
to the marginal ridges of the organism. Both F. ukrainica and F. oblonga are also well comparable to the type
materials of Ukraine in the preservation of concave
(negative relief) and convex (positive relief) with
oral/atrial siphons, double marginal ridges/grooves
and elevated edges in the Sonia Formation. The Finkoella fossil remains are believed to be the flattened bodies
of tunicate organisms. Similar sack-shaped Burykhia
fossils recorded in the White Sea of Russia contrasted
to sponges and similar hollow-shaped organisms have
been interpreted and compared with lichenized fungi
and fungal affinity. Thus, the biological affinity of the
Finkoella organism is still unresolved.

Keywords: Activity concentration, density, detector, natural radioactivity, self-absorption.
Abstract: In the present article, a methodology has been discussed
to evaluate the influence of activity concentration of
soil samples containing heavy metals in the environment.
The approach leverages a simulated germanium detector and a cylindrical geometry sample configuration to
analyse soil samples with varying densities. The results
showed a positive correlation between the soil densities
and activity concentration, with an average correlation
coefficient of 0.99 indicating that variations in density
affect the activity concentration measurements. To
mitigate this error, a demonstration of the self-absorption correction as a function of density, being an essential part of the present study has been included.

Subject: Limitations of catchment area estimates and river basin boundaries from the Central Water Commission and the water resources information system
Keywords: Catchment area, Central Water Commission, Ganga, hydrology, remote sensing
Abstract: Geospatial information on river gauging stations, such as station locations, catchment boundaries,
river flow paths and other hydrographic data are basic building blocks of hydrological analyses.
Such information for India’s river basins is available from Central Water Commission (CWC) and
water resources information system (WRIS), but is limited in extent and unreliable. Using widely
used global hydrography products, catchment boundaries were delineated for 100 gauging stations
in the Ganga river basin (GRB), and their catchment areas were estimated. The delineated boundary
for the GRB, and also station-wise catchment areas from the present study were much more consistent
with global hydrography products than those available from CWC and WRIS. Lack of reliable, analysis ready hydrography data is a hindrance to hydro-climatological research. The long-term objective of
this study is to help build such a needed dataset using high-resolution remote sensing products.

Subject: Setting up and operationalization of the real-time flood forecasting – spatial decision support system for Chennai, India
Keywords: None
Abstract: Estimates by the Central Water Commission (CWC) on flood damage to crops,
houses and public utilities from 1953 to
2020 is about Rs 4 lakh crores (INR 4 trillion)1
. Therefore, a comprehensive flood
forecasting and early warning framework
for India is essential to mitigate the above
damage. The main input for flood forecasting is the availability of dependable rainfall forecasts. Despite the stochastic nature
of rainfall forecasts, the methodologies
adopted in India for flood forecasting are
mostly deterministic in nature. Hence, there
is a need to translate the ensemble rainfall
forecast into an ensemble hydrologic prediction by integrating meteorologic forecast, hydrologic and hydraulic models
.
With the advancement of science, reliable
rainfall forecasts are made possible with
sufficient lead time from many weather
forecasting models.

Subject: Assessment of agricultural land area lost due to Brahmaputra riverbank line erosion in Assam
Keywords: None
Abstract: The River Brahmaputra is characterized by
its exceedingly large flow, enormous volume of sediment load, continuous changes
in channel morphology, rapid bed aggradations, bank line recession and erosion.
Heavy rainfall, associated with severe
flooding, excessive siltation and migration
of river channels, causes erosion on both
sides of the Brahmaputra river. The river
has a braided channel in most of its course
in the alluvial plains of Assam, and the
river flows through 21 districts of the state.
The braided nature, lateral changes in
channels and continuous migration of rivers
cause severe erosion along the banks, leading to a considerable loss of good fertile
land each year. Shear failure due to undercutting upper bank materials during high
flooding and over-steepening of bank materials also leads to bank failures in both
the banks1–3
. Damages caused by erosion
run into several hundred crores every year.
Bank erosion by the rivers has been a serious issue for the last six decades as more
than 4.27 lakh hectares (ha) of land have
already been eroded by the River Brahmaputra and its tributaries since 1950, which
is 7.40% of the area of the state. As assessed, the annual average loss of land is
nearly 8000 ha. The width of the River
Brahmaputra has increased to 15.00 km in
some places due to bank erosion (https://
waterresources.assam.gov.in/portlets/flooderosion-problems).

Subject: Propelling Indian economy through space exploration and applications
Keywords: None
Abstract: The performance of the global economy is
supposed to be ruled by the economies of
each country1
. With this, the economic instability that countries experience during
global crises creeps in, as evident from the
Global Economic Outlook Report 2020,
which emphasized how the COVID-19
pandemic affected the global economy2
.
However, when it comes to the space
economy, countries seem to show resilient
support for multiple reasons, as evidenced
by research from Morgan Stanley, which
expects the global space industry to grow
into a US$ 1.1 trillion market by 2040,
from about US$ 350 billion in 2016 (ref. 3).
One of the reasons is that the various space
stakeholders use a sustainable approach to
space research. For example, in scenarios
where stakeholders from one country specialize in cost-effective satellite launches,
support other countries to launch their satellites into orbit, thereby reducing resource
wastage and effective utilization of financial resources. Other reasons include investor sentiments, which lead to volatility in the
stock market (changes in support and resistance), thus affecting the returns4
. Such
an effect was not seen in the space industry,
as the effect of support and resistance on
the overall share market did not affect the
space companies due to most of them not
being listed in popular stock exchanges, for
example, SpaceX and Skyroot Aerospace
Private Limited5
. This resulted in an ultimate decline in costs for space-based ventures, resulting in the realization of the very
celebrated aspiration of ‘SPACE FOR ALL’,
as obvious from making spacesuits for
women3
, which earlier were not a priority

Subject: Hundred years of research on Drosophila ananassae has revealed a number of unusual features of this species
Keywords: None
Abstract: Drosophila ananassae was originally described by Doleschall in 1858 from Ambon Island in Indonesia. This
species came into notice when Morgan, Bridges and Sturtevant compiled data in a volume entitled ‘The Genetics of Drosophila’ in 1925 as D. caribbea Sturtevant in the chapter ‘other species of Drosophila’. Kikkawa in
1935 verified D. caribbea as D. ananassae. The first mutation in this species was curved wing, an autosomal recessive gene on II chromosome reported by Sturtevant in 1921. Since then D. ananassae has been utilized extensively for different kinds of studies and results of these studies conducted during the last hundred years have
clearly revealed that D. ananassae is genetically unique species and stands distinct from other species of the
genus Drosophila. The important unusual features of this species are: spontaneous meiotic male recombination,
presence of chiasmata in males, high mutability, optic morphology hyper mutability system, absence of genetic
coadaptation, Y-4 linkage of nucleolus organizer, high frequency of pericentric inversions and translocations,
population substructing, parthenogenesis, extra chromosomal inheritance, incipient sexual isolation, inversion
karyotypes and mate recognition system, spontaneous genetic mosaic, segregation distortion, lack of correlation
between crossing-over and chromosome distance between inversions, rare male mating advantage, trait and sex
specific fluctuating asymmetry, female and male remating and sperm displacement, speciation in south Pacific
populations, association with a bacterium Wolbachia, variation in resistance to environmental stress, nutrition
regulated stress resistance, correlation between inversion karyotypes and mating propensity and phylogenetic
relationship with its sibling D. pallidosa which is in statu nascendi
