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.

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.

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.

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
