Subject: Hot springs of Demchok, Ladakh, India
Keywords: Geothermal zone, hot springs, ion-exchange process, medicinal properties, water–rock ratio
Abstract: In this study, two thermal springs are reported from
the Demchok area in Ladakh, India. These are characterized by water having low total dissolved solids (TDS)
content (~250 mg/l) as well as high pH (9.5) and surface
temperature (75°C). Although these hot springs and
their medicinal properties are known to locals, they have
not been scientifically studied. Relatively low TDS despite high temperature could be due to sluggish ion exchange processes in the geothermal reservoir. Such a
situation might have developed because of the high-water to-rock ratio and/or smaller residence time of the geothermal fluid in the reaction zone.

Keywords: Collection efficiency, flight pattern, male stingless bees, water trap.
Abstract: A large-scale evaluation of water traps for their efficiency
in trapping male stingless bees was done, which involved
41 locations from 9 states and 88, 7 and 5 stingless bee
colonies of Tetragonula, Lepidotrigona and Lisotrigona
species respectively. We succeeded in collecting male
bees in 82 colonies of Tetragonula spp., five of Lepidotrigona spp. and two of Lisotrigona spp. The male bees
were trapped throughout the year with more than 10
males/colony in March, April, July, September, October
and December. Males of Tetragonula, Lepidotrigona
and Lisotrigona formed 0.17–14.29%, 0.54–21.53% and
12.35–14.21% of the total bees trapped per colony respectively. We conclude that a water trap is the best
technique to collect male bees of all three genera
(Tetragonula, Lepidotrigona and Lisotrigona) occurring
in India within a brief period during any time of the
year.

Abstract: The present study records the triangular-shaped Ediacaran fossil identified as Thectardis avalonensis from
the Sonia Sandstone of Jodhpur Group, Marwar Supergroup, western India. These Ediacaran fossil specimens
are preserved in convex (positive) relief, but one is in
negative relief on the bedding planes of sandstone in the
Sursagar mines area. T. avalonensis is well-preserved,
unskeletonized, elongated and triangular in shape, with
sharp, raised marginal rims or ridges that widen at the
triangular base and taper towards the apex of the organism. This Ediacaran triangular-shaped T. avalonensis
organism is recorded for the first time from India. The
phylogenetic affinity of T. avalonensis is still uncertain,
as some have interpreted it as a sponge based on a body
plan consistent with the hydrodynamics of the sponge
water-canal system, which lacked a mouth or movement
and its length–width ratio of more than 1.6. As well as
these, T. avalonensis may also belong to Diskagma-like
lichen or living Cladonia-like lichen group and the Auroralumina-like cnidarian organisms of the Ediacaran
crown group.

Subject: Dynamic response of anchoring layered rock slopes subjected to seismic loads
Keywords: Anchor bolts, anti-seismic effect, dynamic response, layered rock slope, seismic loads.
Abstract: The seismic dynamic responses of rock slopes are a hot
topic for geotechnical engineering studies. Based on
the interaction between rock slope and anchor bolts, a
dynamic numerical model of a layered rock slope was
developed using the finite difference software FLAC3D.
The dynamic response patterns of anchored and natural
slopes under seismic loads were analysed to obtain the
supporting effect of anchor bolts during seismic activity.
The results indicate that under seismic loads, tensile
cracks at the intersection of the top and joint surface
develop into a drawing open surface of the back edge,
and a shear slip occurs at the base of the slope, both of
which result in the formation of tensile-shear slip failure.
Permanent slope displacement accumulates only when
seismic acceleration exceeds the critical acceleration.
The slope deformation has been constrained, and the
performance of the slope during the seismic activity has
been strengthened by anchor bolt supports, which significantly increase the ductility of the rock slope under
seismic loads. Moreover, during an earthquake, the axial
forces of anchor bolts in the middle slope rise more
than at any other position. After the earthquake, anchor
bolts in the middle have been shown to exhibit maximum axial force. As a complex problem, stability analysis
of seismic slopes is important. The analysis of seismic
slope failure and the mechanism of slope anchoring are
particularly complicated. The present study will help to
improve future research on the seismic design and dynamic analysis of slopes supported by anchor bolts.

Abstract: A multi-sensor-based instrumentation system was assessed under static and dynamic conditions to precisely
measure a tractor-implement performance in the field.
The system was evaluated using a tractor and three different implements, viz. 11-tyne cultivator, three-bottom
ridger and nine-row spatially modified no-till drill. The
final results were compared with conventional measurement techniques. The range of disparity for wheel slip,
draft, inclination angle, fuel consumption, radiator fan
speed and forward speed was 4.24–5.99%, 2.63–4.95%,
2.68–7.20%, 3.78–5.64%, 3.37–4.81% and 3.04–4.97%
respectively. The system could measure real-time variations in the field and proved to be an energy- and timesaving device.

Subject: Machine learning algorithms for categorization of agricultural dust emissions using image processing of wheat combine harvester
Keywords: Agriculture, combine harvester, dust and straw particles, image processing, machine learning.
Abstract: India is the second largest wheat producer in the world
after Russia. Wheat harvesting in the country was traditionally done using a sickle, a hand tool. However, in
the last two decades, combined harvesters have been extensively used. The rapid development of mechanization
has resulted in the production of dust and straw particles
during the harvesting operation of wheat. These particles have severe health hazards for the machine operator.
Exposure to various types of particulate matter has a variety of effects on human health. Such an effect can be
minimized if the concentration of the generated particle
is maintained within a permissible limit. Hence, the
present study has been conducted to evaluate and categorize dust and straw particles in the workspace of a
combine harvester operator during wheat harvesting. An
image-processing technique was used to study a field
data sample collected on sticky paper. It describes a novel
method of collecting dust and straw particles while harvesting wheat. Few studies have been conducted in developing countries to analyse the characteristics of dust
and wheat straw exposure of combined harvester operators. The number of dust and straw particles deposited
per square millimetre was 9–12, with sizes ranging from
10 to 1400 µm. The extracted data were divided into three
groups, viz. thoracic, inhalable and straw and modelled
using machine learning algorithms, including support vector machine (SVM) and k-nearest neighbor. With an accuracy of 96%, SVM outperformed the other methods
for categorising dust and straw particles, whereas linear
discriminant analysis performed poorly with an accuracy of 88%.

Subject: Deep learning technique for forecasting the price of cauliflower
Keywords: Cauliflower, deep learning technique, machine learning, statistical models, vegetable prices
Abstract: Vegetables are the staple food in our diets. Vegetable
prices are difficult to forecast because they are influenced by a variety of factors, including weather, demand
and supply chain, Government policies, etc. and exhibit
volatile fluctuations. Marketing of vegetables is complex,
especially because of their perishability, seasonality and
bulkiness. An accurate and timely forecast of vegetables is essential to help its stakeholders. Previous studies
observed that traditional statistical models are unable
to capture the complex behaviour of vegetable markets.
In this study, a comparative assessment has been carried
out among the traditional time-series model, machine
learning and deep learning techniques in order to find
the best-suited model. For empirical illustration, cauliflower markets have been chosen as it is one of India’s
most important and popular winter. In order to identify
the complexity in the price of cauliflower, the machine
learning technique, i.e. artificial neural network and
deep learning technique, i.e. long short-term memory
model have been implemented. In addition, the traditional stochastic time-series model, i.e. autoregressive integrated moving average model, was used to compare
the prediction accuracy of the above models. To this
end, the moving window forecast approach was also
implemented to evaluate the sensitivity of these models
with respect to forecast length. It can be concluded that
the deep learning model outperforms the traditional
time-series model and the machine learning technique
for both short- and long-term forecasting.

Abstract: The present study was conducted to ascertain the gene
action and inheritance of yield and various yield-attributing traits and to screen the simple sequence repeat
(SSR) markers for parental polymorphism in bitter gourd
(Momordica charantia L.). Two contrasting parents (S-2
and Pusa Purvi) were used for hybridization. Parental
polymorphism was analysed using 100 SSR markers.
DNA amplicon of size around 150–250 bp in both the
parents was obtained for the 10 polymorphic SSR markers. These were used to ascertain the hybridity of F1
progeny, from which the subsequent generations were
developed. Generation mean analysis, ABCD scaling
test and joint scaling test were performed using the observations from six generations (parent-1, parent-2, F1,
F2, back cross 1 and back cross 2). The additive effect
of the genes was predominant for the quantitative
traits like fruit length, diameter, weight, etc. Duplicate
epistasis was observed for the majority of traits. The
yield per plant was positively correlated with fruit
length, diameter, weight and fruit number per plant.
Chi-square test revealed the monogenic inheritance of
qualitative traits (fruit tubercles and ridgeness, and
shape at apex), in which ‘conspicuous tubercles’, ‘discontinuous ridgeness’ and ‘acute fruit shape at apex’ were
dominant. These results reveal the complexity and polygenic nature of the yield. The findings obtained from
the present study can be used for yield improvement in
the future. For this, the polymorphic SSRs identified
can also be used in genetic diversity studies, DNA fingerprinting, genetic mapping, genomics analysis, etc.

Abstract: Integrated farming system (IFS) approach is a powerful
tool for ensuring the livelihood security of small and marginal farmers. The precision of IFS experiments can be
enhanced using statistical and computational tools. Twopart designs are helpful in selecting the best possible
components in IFS. They involve two groups of treatment
arranged in incomplete blocks with respect to both
groups, and the concurrence of treatment pairs within
and between groups is constant. The fusion of two incomplete block designs in a systematic manner can yield
two-part designs. Further, for situations where certain
experimental units are not available, two-part structurally
incomplete designs are proposed

Abstract: The institutional herbal garden for North East region (NER) of India was established in 2014 wherein medicinal and aromatic plant (MAPs) species were brought from different ecologies experienced
differential survival. This triggered the participation of local citizens in developing the science of
herbal biodiversity in this region. Consequently, MAPs were collected from the forest and farmers’
fields in different parts of NER. This resulted in better survival of the species from tropical to subtemperate conditions of NER. Over eight years, 164 MAPs have been conserved in the herbal garden
representing 60 families comprising herbs (84), shrubs (45), climbers (15), trees (15) and grasses
(5). The herbal garden at Pasighat conserves over 50% of the species documented nationwide including
nine of the threatened species of India. Thus, the herbal gardens endorsing citizen science is instrumental for the widespread sharing of scientific expertise and stewardship on healing herbs.

Abstract: The Karankadu mangrove forest is situated
in Ramanathapuram district, Tamil Nadu,
India. Falling under the Gulf of Mannar
Marine National Park, this human-made
mangrove forest is important to the surrounding ecosystem. This area is present
between Ramanad–Thondi East Coast
Road. The Karankadu mangrove swamp lies
at 9°36′N lat. and 78°83′E long. and is situated in the Palk Bay region of the southeast coast of India. It has a long coastline
(around 241 km). About 40–50 years ago,
the Karankadu village was surrounded by
Prosopis species (Karachedi). The area
was deforested for living, and hence the
village is named Karankadu. Hunting of
birds and fish is the main livelihood of the
villagers. Earlier, this area was dry and
backward. The Ramanathapuram district receives rainfall under the influence of both
southwest (SW) and northeast (NE) monsoons, with the latter being the chief contributor. Most of the precipitation occurs in
the form of cyclonic storms caused by depressions in the Bay of Bengal.

Abstract: Life originated in the ocean and thus it is the single most
reason to protect the ocean environment. Oceans supply
food, energy, mineral resources and are storehouses of biodiversity; they influence weather and climate and provide
an ecosystem for sustaining human life and other biota.
Oceans are the major source of fossil-fuel-based energy and
influence the economy of the world and thus also are of
strategic importance. It is imperative that future growth and
prosperity will be dependent on oceans in view of the impacts of climate change on sustainability. For the same reason, the UN Conference on Sustainable Development in
2012, stressed expanding the green economy to a blue economy. The conservation and sustainable utilization of the
oceans, seas and marine resources have been identified as
one of the UN Sustainable Development Goals (SDGs). Considering the importance of ocean development, UNESCO/
International Oceanographic Commission (IOC) has declared the current decade as the ‘Decade of Ocean Science’ to
deliver the science needed to achieve SDG-14, ‘Life under
Water’. Prime Minister Narendra Modi has recognized the
vital role of the ocean-dependent economy for future development and very aptly articulated the importance of the blue
economy as follows: ‘To me, the blue chakra or wheel in
India’s flag represents the potential of the blue revolution,
or the ocean economy’. As oceans are going to play a stellar
role in global development, it is vital that G20 under India’s
Presidency gives sufficient importance to develop the blue
economy for global good.

Abstract: Adivasis and other traditional forest dwellers have been living in the forests from time immemorial. Yet their rights over their lands and forests were never properly recognized and recorded during the forest settlements process, even after India's independence.
This made them 'encroachers' in their homelands and deprived them of the rights and security of tenure over their lands and forests, which is why have been living a life of extreme poverty and hunger amid areas rich in forests and other natural resources.
