Subject: Diversity and role of flower visitors in onion seed production
Keywords: Floral biology, foraging ecology, onion, pollinators, species diversity.
Abstract: Onion flowers attract a wide range of visitors, including
pollinators. Many factors influence the abundance of
floral visitors in onion, such as flower size, shape, colour,
weather parameters and the availability of floral rewards. Quality seed production in onion (Allium cepa
L.) is mainly driven by insect pollinators because of its
protandrous nature and cross-pollination. The type of
flower visitors, their numbers and the time of their visitation determine the pollination efficiency. Bees are the
major pollinating agents in onions under natural conditions. However, using chemical pesticides against pests
and diseases of onions during bloom decreases the diversity in and around crop fields. Anthropogenic factors like
urbanization could have negative impacts on insect pollination services. Therefore, it is critical to adopt a sustainable approach to retain and conserve the existing insect
pollinators and their diversity in the onion ecosystem. In
this study, we review the research work done so far on the
diversity and role of flower visitors and pollinators in
onion seed production and the various factors affecting
their survival and services in the onion ecosystem.

Subject: Elasmobranch conservation, challenges and management strategy in India: recommendations from a national consultative meeting
Keywords: Consultative meeting, elasmobranch, fisheries, management and conservation, regulations.
Abstract: Historically, India has been projected as one of the major elasmobranch fishing nations in the
world. However, management and conservation efforts are not commensurate with this trend. Along
with the Wildlife (Protection) Act, 1972, several generic conservation measures are in place at the
regional/local level. But India is still a long way from meeting global conservation commitments. We
present here the status of elasmobranch management and conservation in India, with the specific objective of identifying the gaps in the existing set-up. We also present recommendations based on a national
consultative workshop held at the Central Marine Fisheries Research Institute, Kochi, in February
2020. We recommend the implementation of a National Plan of Action (NPOA-Sharks) and more inclusive governance and policymaking for elasmobranch conservation in India.

Abstract: Dewinged termite imagoes are considered to be delicious
human food around the world. The nutrient composition may vary with respect to the species. In the present
study, imagoes of three termite species, viz. Odontotermes obesus, Coptotermes heimi and Microtermes obesi
were used to compare their protein composition. Additionally, the commonest species, O. obesus was used for proximate and mineral composition analysis. The nutritional analysis of termites indicated a higher percentage of protein in C. heimi, followed by O. obesus. The
proximate analysis of O. obesus imagoes revealed a
higher proportion of crude fat followed by crude protein.
Macrominerals were recorded in a higher proportion
with potassium as one of the major minerals followed
by sodium, while in microelements iron and zinc were
represented in greater quantities.

Subject: Anomalous uranium concentration in tourmaline-bearing leucogranite of Higher Himalaya, Nuranang, Tawang district, Arunachal Pradesh, North East India
Keywords: Geochemistry, leucogranite, mineralogy, petrology, tourmaline, uranium mineralization
Abstract: Here we report anomalous uranium concentration in
tourmaline-bearing leucogranite occurring at Nuranang,
Tawang district, Arunachal Pradesh, North East India.
The leucogranite occurs as concordant layers parallel to
gneissic foliation, similar to the gneisses of the Paleoproterozoic Se La Group. It is medium to coarse-grained,
and is composed of quartz, potash feldspar and plagioclase as dominant minerals with variable proportions of
muscovite, biotite, tourmaline and garnet. Apatite, zircon
and pyrite are accessory minerals. Geochemically, the
leucogranite is alkali-rich, peraluminous and highly
differentiated. It is emplaced in a syn to late orogenic
collision tectonic setting. Analyses of 10 granite samples
collected at 500 m intervals show relatively high radio elemental concentration (U: 5–96 ppm, Th: 5–23 ppm,
K: 2.23–7.72% and Th/U; 0.07–1.00, n = 10) compared
to normal granite. Anomalous uranium concentration in
the leucogranite is observed in a 200 m × 50 m area at
Nuranang. Samples from this area have assayed 0.016–
0.029% U3O8 and <0.005% ThO2. Leachable U3O8 content determined in five samples varies from 81.25% to
87.50%. Preliminary studies indicate that uranium is
in the adsorbed state associated with iron oxide and altered feldspar/clay. The findings of anomalous uranium
concentration in tourmaline-bearing leucogranite likely
open up a new target area for uranium search in the
Higher Himalaya of Arunachal Pradesh

Subject: Evaluation of fixation and reaction gaze points near speed humps on urban roads in India
Keywords: Eye tracker, gaze plots, heat maps, regression analysis, speed hump, urban roads.
Abstract: Isolated speed humps are extensively used as speed-calming measures for motorized vehicles of different categories on urban roads. Most urban roads in India are
provided with either a trapezoidal or circular speed
hump based on the road category. The height of these
humps influences the per cent reduction of speed at the
crown of the hump. It has been observed that passenger
motorized vehicles do not reduce their speeds before a
speed hump, even when it is large. The objective of this
study was to evaluate the driver perception and reaction
distance near a speed hump and thereby examine the
sensitivity of these parameters on the drivers of different
age groups. For this, drivers of different ages (a total
sample size of five subjects) were considered for real-time eye-tracking experiments. The experimental results
of all subjects’ eye tracking images were examined in
this study. The visit duration or dwell time for an area
of interest (AOI) was estimated and compared among
various drivers. The speed data were also collected using
a velocity-box along with eye-tracking data of each driver at the identified location. The collected eye-tracking
experimental data were analysed using statistical techniques. Regression analysis between vehicular speed and
fixation count was performed. It was observed that the
power model was the best fit for the collected data. The
visualization data helped to reveal the characteristics of
fixation and reaction gaze points near the identified
speed humps. The study results showed that driver attention was double when vehicle located between 0 and
20 m than 20 and 40 m from the speed hump. Drivers in
the age group between 20 and 25 years had 48% AOI of
visit duration, while for those in the age group between
30 and 40 years, it was 67%.

Subject: Vegetative propagation of papaya (Carica papaya L.) through grafting
Keywords: Cytokinins, grafting, lateral shoots, papaya, vegetative propagation.
Abstract: In papaya orchards raised through seedlings, large variation in sex forms is a major hindrance to its cultivation on
a commercial scale. Similarly, in papaya breeding, if a
desirable trait is to be fixed in future generations, it is
essential to multiply the plants by asexual means for
evaluation on a large scale as sexual propagation has
several drawbacks. Limited studies have been conducted
on vegetative propagation in papaya under the tropical
climate of India. Hence, the present study was initiated
to standardize vegetative propagation through grafting
under separate experiments. A combination of growth
hormones and different aged seedlings was used to induce lateral shoots on the mother plants to utilize them as
scions for grafting. Spraying BA @ 100 ppm + GA3 @
250 ppm on 5–6 month-old mother plants could produce
more graftable size shoots. Among different methods,
softwood wedge grafting recorded maximum success
followed by cleft grafting. Field evaluation of grafted
and seedling plants revealed that the former were
dwarfs and sturdy, induced early flowering at a lower
heights and came to harvest earlier than the seedlings.
Though physical fruit parameters showed a significant
difference between grafted and seedling plants, no difference was recorded for fruit quality parameters.

Subject: Aromatic plant odours of Anethum graveolens and Coriandrum sativum repel whitefly, Bemisia tabaci in tomato
Keywords: Aromatic intercrops, Bemisia tabaci, headspace volatiles, pest management strategies, tomato
Abstract: We studied the behavioural responses of female whitefly,
Bemisia tabaci (Gennadius) towards headspace volatiles of tomato in the presence of aromatic intercrops,
namely coriander (Coriandrum sativum L.) and dill
(Anethum graveolens L.) using olfactometer bioassays,
electrophysiological techniques and field experimentation. Olfactometer studies revealed the repellent nature
of dill and coriander. Multiple-choice olfactometer studies revealed less residence time in tomato with coriander
(T + Co; 1.33 0.20 min) and tomato with dill (T + D;
1.97 0.30 min) treated arms compared to sole tomato
volatile treated arm (3.18 0.35 min). Field studies also
supported this trend, where significantly less whitefly
incidence was recorded in treatment T + Co (2.34
0.39 per three leaves) or T + D (3.33 0.51 per three
leaves) compared to sole tomato crop (5.71 0.75 per
three leaves). In coupled gas chromatography-electroantennodetection (GC-EAD) studies, whitefly antenna
responded to several compounds of dill and coriander.
This study suggests that aromatic plants such as dill
and coriander can be used as potential intercrop components in tomatoes to manage B. tabaci and the GCEAD-identified compounds of dill and coriander will
help formulate futuristic semiochemical-based pest management strategies against the whitefly.

Subject: Archaeo-metallurgical analysis: metallurgy in the early medieval societies of Moghalmari, West Bengal, India
Keywords: Ancient metals, archaeo-metallurgy, early medieval sites, human civilization, scientific analysis.
Abstract: Archaeo-metallurgical studies on early medieval Bengal
trace, the history and development of metalwork. West
Bengal, as an integral part of eastern India, has an ancient tradition of iron technology, as indicated by the
metal objects obtained from various archaeological
sites. All materials collected from these archaeological
sites in West Bengal prove that the ancient alchemy
and metallurgical science practised in the region were
vast and rich. The detailed description of metallurgical
processes and intricate properties of minerals and chemicals in the 10th–11th century alchemy-text, Rasaratna
Samuchchaya, is yet another proof of the high level of
knowledge on metallurgy. Metals have a close relationship with human civilization, and the phases attributed
to different stages of cultural growth are dominated by
the metals being used at a particular period. Metal objects found in various early medieval sites of West Bengal
provide a unique opportunity to study the development
of metalworking fashion and technology. Several excavations and explorations have been conducted to study
the societal structure and material culture of this period.
The study of metal technology also provides information
on cultural development and craftsmanship. The present study involves scientific analysis of metal objects
(bronze) obtained from the culturally rich archaeological
site of Moghalmari in West Bengal. X-ray diffractogram which revealed the composition of the materials.
Scanning electron microscopy was used to analyse the
microstructure of the sample. The results provide information regarding the purity and composition of the
metal.

Subject: A data-driven approach to predict anthropometric dimensions of Central Indian women workers via principal component and factorial analysis
Keywords: Agriculture, correlation, factor analysis, principal component analysis, women worker
Abstract: In India, the contribution of women workers in agriculture is steadily increasing daily, which governs a major
share of the Indian agriculture sector. Hence farm tools
and equipment must be designed by considering regionspecific anthropometric data of women workers. However,
measuring and recording anthropometric dimensions is
time-consuming and economically taxable. In the present
study, regression models have been developed to predict
different anthropometric dimensions using anthropometric data of 79 body dimensions of 720 women workers in
central India aged between 25 and 55 years. Principal
component and factorial analysis techniques were employed to extract significant body dimensions. The major
objective of this study was to predict various anthropometric dimensions by regression models so that the time
and effort required for several body dimension measurements would be reduced.

Keywords: Adolescent girls, general and central obesity, healthy eating habits, junk food
Abstract: Deterioration in health due to junk food consumption
is a global concern, with adolescents at a greater risk.
A cross-sectional study was conducted to understand
the dynamics of junk food consumption with obesity
in adolescent Tibetan girls (13–18 years; N = 276) of
Himachal Pradesh, India. A pretested schedule and
anthropometric measurements were used for data collection. Descriptive and bivariate analysis was done.
The odds ratio was the determined. The study found
that 45.28% of the girls consumed some form of junk
food. Also, 25.4% and 16.3% were also centrally obese
according to waist–hip ratio (WHR) and waist–height
ratio (WHtR) respectively. Girls who consumed junk
food were found to be at a greater risk (WHR: OR =
7.942, 95% confidence interval (CI) = 4.132–15.262;
WHtR: OR = 3.652, 95% CI = 1.820–7.327 at P < 0.001)
of developing abdominal obesity. Frequent consumption
of junk food was found to be remarkably high (77.60%)
among the studied population. It is of utmost importance to prioritize implementation programmes on
healthy eating habits through various government and
non-government agencies in order to improve health
among adolescents.

Subject: Prediction and attenuation of ground vibrations generated by moving trains
Keywords: Mass spring systems, mitigation measures, seismic velocity, vibration attenuation.
Abstract: The vibration generated by underground trains and the
level of vibration attenuated along the propagation path
are the keys to designing mitigation measures to avoid
adverse effects on the surroundings. The attenuation of
vibrational energy due to geometrical and material damping was determined at the Civil Court Godown, Pune
Metro, Maharashtra, India, up to 30 m. The seismic
cross-hole test was used to determine the dynamic
properties of the soil. It was found that the soil stratum
was homogeneous and composed of basaltic rock. The total
vibration level reaching the receiver was predicted for
trains travelling at 80, 250 and 350 km/h, and vibration
attenuation measures such as steel mass-spring systems
and polyurethane mass-spring systems have been proposed.

Subject: Design and study of BiVO4/MnCo2O4 nanocomposites for visible light-driven antibacterial applications
Keywords: Antibacterial applications, Escherichia coli, nanocomposites, semiconductor, synergistic effect
Abstract: In this study, BiVO4 and MnCo2O4 were synthesized
successfully using hydrothermal and co-precipitation
methods. Nanocomposites of BiVO4/MnCo2O4 of varying
composition were made by calcination. All the synthesized compounds were well-characterized using PXRD,
SEM, EDS and DRS. Powder XRD analysis confirmed
the formation of BiVO4, MnCo2O4 and their respective
well-defined composites. The band gaps of the materials
were in the visible range (1.16–2.36 eV), making them
suitable for visible light-driven antibacterial applications
to inactivate the Gram-negative bacterium Escherichia
coli. The as-prepared composites exhibited superior
antibacterial activity (maximum of ~80%) than the parent compounds, possibly due to the synergistic effect.

Subject: Evaluation of the factors affecting hydrodynamic characteristics of a hybrid anaerobic baffled reactor
Keywords: Anaerobic baffled reactor, dead space, hydraulic efficiency, residence time distribution, response surface methodology.
Abstract: The residence time distribution was used to study the
hydrodynamic behaviour using the pulse input tracer
technique. The effect of medium, compartment-wise
variation in the mixing patterns inside the reactor and
hydraulic retention time on the hydrodynamic characteristics of the reactor was studied. The influence of the
number of compartments was predominant compared
to the hydraulic retention time and presence of a medium. The flow regime in the first, second and third compartments was in the intermediate state whereas the
flow regime was in plug-flow state in the rear compartment. The interactive effects were evaluated using
response surface methodology.

Subject: Status of biofortification in tropical root and tuber crops
Keywords: Biofortification, hidden hunger, nutrient-smart agriculture, transgenic crops, tubers
Abstract: Hidden hunger is a form of malnutrition, afflicting one-third of the world’s population. It is caused due to the
lack of micronutrients, mainly iron, zinc and vitamin
A, in the human diet and can lead to mental impairment,
poor health, low productivity and even death. It is
common in many developing and developed countries.
A change in research focus from increased agricultural
production of calorie-rich staple crops to nutrient-dense
staple crops is crucial to address the above problem.
Biofortification is a process of increasing the density of
vitamins and minerals in a crop through plant breeding,
transgenic or recombinant DNA technology or agronomic practices. Biofortification through breeding has been
taken up as a challenge by Harvest Plus for cassava and
sweet potato, which has resulted in the release of many
biofortified varieties that could fight hidden hunger
and ensure food security in many Sub-Saharan African
countries. The BioCassavaPlus project adopted transgenic strategies for biofortification in cassava. Transgenic
approaches serve as an alternative for biofortification
in sweet potatoes. Harvest Plus has not included yam in
its biofortification programme, though increasing the
provitamin A carotenoid content of yam is much needed.
Bioavailability of micronutrients has been thoroughly
studied in sweet potatoes. In India, the ICAR-Central
Tuber Crop Research Institute (CTCRI), Thiruvananthapuram has been involved in the biofortification of
tropical tuber crops and has released many biofortified
varieties in sweet potato, cassava and yam. In a collaborative work plan with CIP, ICAR-CTCRI is at present
involved in the development of biofortified varieties of
sweet potato. The need to release and adopt transgenic
biofortified crops is discussed here, as sweet potato is a
naturally transgenic crop
