Subject: Unambiguous detection of OH and H2O on the Moon from Chandrayaan-2 Imaging Infrared Spectrometer reflectance data using 3 µm hydration feature.
Keywords: Imaging infrared Spectrometer, Lunar hydration, Moon, Reflectance data, Thermal correction
Abstract: Imaging Infrared Spectrometer (IIRS) on-board Chandrayaan-2 is designed to measure lunar reflected and emitted solar radiation in 0.8-5.0 µm spectral range. Its high spatial resolution (~80m) and extended spectral range is most suitable to completely characterize lunar hydration (2.8-3.5 µm region) attributed to the presence of OH and/or H2o.Here we present initial results from IIRS reflectance data analysed unambiguously detect and quantify lunar 3 µm absorption feature. After pre-processing and data-reduction, a physics based thermal correction analysis of IIRS reflectance spectra has been done using co-located temperature measurements. Hydration absorptions observed at all latitudes and surface types with varying degrees for all pixels in the study area and its absorption depth shows distinct variability associated with mineralogy, surface temperature and latitude.

Abstract: Salinity is a critical feature for the management of agricultural soil, particularly in arid and semi-arid areas. The present study was conducted to develop an effective soil salinity prediction model using Sentinel 2A (S2) satellite data. Initially, the collected soil samples were analysed for soil salinity (ECe). Subsequently, multiple linear regression analysis was carried out between the obtained ECe values and S2 data, for the prediction of soil salinity models. The relationship between ECe and S2 data, including individual bands, band ratios and spectral indices showed moderate to highly significant correlations (R2 =0.43-0.83). A combination of SWIR-1 band and the simplified brightness index was found to be the most appropriate (R2=0.65; P<0.001) for prediction of soil salinity. The results of this study demonstrate the ability to obtain reliable estimates of EC using S2 data.

Subject: Assessing the energy efficiency practices in cities across the world
Keywords: Best practices, embodied, energy-efficient urban planning, greenhouse gases, operational and transport energy
Abstract: Urban areas consume early two-thirds of the global energy and are responsible for 70% of overall green-house gas emissions. This energy can be broadly classified into three categories, i.e., embodied, operational and transport. Energy-efficient urban planning is an attempt to reduce the use of non-renewable energy sources, without sacrificing the quality of service. The strategies formulated for addressing energy efficiency will be targeting one or more of the energy efficiency will be targeting one or more of the energy types mentioned above. The present study evaluates the energy efficiency strategies adopted by cities across the world which are cited as best practices by the International Energy Agency. One of the key observations from this study is that most strategies address operational energy, while few address transport energy. For the purpose of assessing the impacts of these strategies, technique for order of preference by similarity to ideal solution analysis was carried out which revealed an overall poor performance score for the case cities, with highest score for Stockholm and lowest for Austin. It is also evident from the study that there is a lack of detailed energy assessment of cities prior to formulation of energy efficiency strategies. This study demonstrates a framework that can be adopted for assessing urban energy efficiency strategies and helps to identify the issues pertaining to current practices.

Subject: Forecasting sector-wise electricity consumption for India using various regression models
Keywords: Electricity consumption, energy policy, forecasting, regression analysis
Abstract: Electricity is an important and one of the most dominant energy sources used in the world. It governs a major share in the Indian as well as world economy. Thus, forecasting its consumption can be useful in better planning of its future production and supply. In the present study, electricity consumption in seven different sectors, namely industry, domestic, agriculture, commercial, traction and railways, others along with total electricity consumed is forecasted using regression analysis. The study uses four regression modelling approaches to forecast electricity consumption by sectors in India. These are linear, logarithmic, power and exponential regression models. The accuracy of the models is tested using R2 (coefficient of determination) and MAPE (mean absolute percentage error) values. The model having the highest R2 and lowest MAPE value is selected for better accuracy results. The result/forecast is then compared with the available data published by the Central Electricity Authority, Government of India.

Abstract: Childhood stunting remains a prominent metric in the health and development of modern India. In Karnataka, India, districts very substantially in stunting prevalence. Here we take a close look at the nature of childhood stunting in the state: its epidemiology, genetics, biology, nutritional basis, environmental contribution, policy and field-based understanding. We explore how these factors interact with one another and suggest ways to target modifiable risk factors for stunting (e.g., nutrition, exposure to infectious diseases, sanitation), which may influence the impact of non-modifiable risk factors (e.g., congenital factors, climate). We suggest that programmes designed to reduce stunting prevalence should accommodate these complex interactions, which could translate to more substantial impact on child health outcomes.

Abstract: The Exploratory study presented here is regarding the implementation of an inquiry-based instructional module developed for undergraduate chemistry laboratory courses. The study aims at understanding the challenges in execution of such a module and suggest ways for its effective implementation. It is important to bring changes in the present conventional practices to develop students as independent investigators and for learning experiences that are inquiry-driven, discussion-based and flexible as recommended by the NEP 2020. Based on this study, we suggest that the transition to inquiry approaches should be gradual. Further, students need adequate scaffolding of the learning process to help them in such a transition.

Keywords: Oldest Birch tree, Western Himalaya, Major climatic events, tree rings
Abstract: Over half a millennium old, precisely dated broadleaved trees are rare across the mountain ranges of the world, including the Himalaya. In dendrochronology, oak is widely used in Europe and North America, but in the Himalaya most of its species are not datable. Except for its two deciduous species, Quercus griffithii and Quercus serrata, most of the Himalayan oaks are diffuse-porous woods and absence of other anatomical features delineating tree ring boundary. In the Indian Himalaya, birch (Betula utilis), popularly known as ‘Bhojpatra’, is a typical alpine tree-line species which has been established as a suitable broad-leaved tree for dendrochronology. Interestingly, it is a ‘diffuse-porous’ tree and the ring boundary is delineated by a light line of terminal parenchyma.

Abstract: The Union Cabinet of India approved the new Pesticide Management Bill in February 2020.This Bill has provisions to regulate industry. However, it does not reflect critical prevailing issues, which are inevitable for reducing and mitigating risks arising from pesticide use. The Bill failed to address post registration risk reduction and mitigation, protection of pesticide users, community and environment. Therefore, the Bill could have poor implications on protecting public health and environment; hence requires critical management.

Abstract: Energy contributes greatly to every aspect of life and other activities and is the main source of economic development of any country. Globally, the demand for electrical power has increased in recent times, causing a major increase in the price of various fuels. Energy production from various renewable and non-renewable resources is not new. However, its impact on the environment is a major concern. Several power plants from large hydro, wind, thermal and others are being used for energy generation; nevertheless the depletion of the environment is the major global concern. The challenges posed to the environment need to be tackled to protect our environment. This study evaluates the state of energy generation and distribution, and its potential environmental impacts on biodiversity, climate change, aquatic life, land use, emission generation, etc. We also propose some environmental management strategies that can help overcome these challenges.

Abstract: Lack of environmental awareness or ignorance regarding the ecological role of animals among children has long-term negative consequence for the biodiversity hotspot in southern India to examine the knowledge level of rural school children regarding the mammalian species in their region. The results of the study showed that school children were able to recognize regional mammalian species that are publicized by media sources but had little knowledge about their conservation status or more significant information about them. Environmental education programmes must focus on making children more aware of the importance of various animals sharing their habitat, so that they have greater knowledge regarding the ecological roles of animals in the ecosystem.

Keywords: Agouti signalling protein, dominant mutation, Funambulus palmarum, melanism, melanocortin-1 receptor
Abstract: This study shows that the dominant mutation of Extension locus in the recessive locus of the agouti Indian three-striped palm squirrel results in constituting an active or hyperactive receptor. This is not inhibited by the agouti antagonist or agouti signaling protein, resulting in melanism. To the best of our knowledge, there is no earlier report of a melanic variant (black) of a three-striped palm squirrel (Funambulus palmaraum Linn) from India. The color change is due to mutation and is traced to melanocortin-1 receptor (MC1R) gene, where it is proved to be sequence alteration causing a frame shift in the extension locus of the wild type. This would have probably caused the constitutive activation of MC1R.

Subject: Native shade trees aid bird conservation in tea plantations in southern India

Abstract: In the Western Ghats, India, we study how different intensities of tea cultivation influence birds. We compared bird communities in conventional monoculture tea and mixed-shade tea plantations, both of which use agrochemicals, with organic tea plantations, a rainforest fragment, and continuous rainforest within the Annamalai Tiger Reserve. In 225-point count surveys, overall bird species richness and abundance were lowest in conventional tea and up to 33 % higher in organic tea.Mixed-shade tea had 40% higher species richness (including 15 canopy and 4 shrub and mid-storey species-primarily frugivores, nectarivores and insectivores), and 83% higher bird abundance than conventional tea, with a greater proportion of forest-affiliated birds and similarity in species composition with forest sites. The rainforest fragment and continuous rainforest had a higher proportion, richness and abundance of forest-affiliated birds and fewer open-country birds, unlike tea plantations where the pattern was reversed. associations of 62 bird species in indicator species analysis revealed similar patterns. Thus, organic tea is better than conventional tea for birds, but mixed –shade tea is even better, although still poorer than forests. Retaining or promoting native shade trees in tea plantations will increase bird diversity and abundance, including of forest-affiliated species and support landscape-level bird conservation.

Abstract: Conspecific herbivores use herbivore-induced plant volatiles (HIPVs) as cues while selecting an optimal site for oviposition. This is ascertain the availability of nourishment for their progeny so that they get the best chance at survival. In the present study phytophagous eulophid seed-borer Anselmella kerrichi was significantly ( time spent: F3,40 =13.12, P <0.0001; number of entries :F2,30 =4.21 ; P=0.02) attracted to HIPVs from immature fruits of java plum, Syzygium cuminii (time spent : 4.77 ± 0.40 min, number of entries: 2.27 ± 0.24), when also given the choice of mature fruits (time spent: 1.76 ± 0.32 min; number of entries:1.46 ± 0.16) indicating that herbivores can assess resource of depletion from host phenology-specific HIPVs. The chemical cues like α-pinene, ẞ-pinene, (ȥ)-ocimene, undecane, 3,7 dimethyl decane, neo-alloocimene, allo-ocimene, ethyl benzoate, 2,6, 11-trimethyldodecane, α-copaene and ẞ-caryophyllene, which are present in immature fruit volatiles elicited antennal response in a GC-EAD analysis. Olfactometer analyses with the synthetic compounds also revealed that A.kerrichi was significantly attracted to these cues and the synthetic blend composed of the above compounds proved to be much more efficient in attracting female wasps when compared to a natural blend. Field evaluations using the synthetic blend showed that it could attract a significant number of A.kerrichi, indicating the scope of using this blend of synthetic HIPVs as sustainable IPM tool.

Subject: Quantitative assessment of BIGV and structural response based on velocity and frequency around an opencast mine.
Keywords: Frequency, ground vibration, opencast mine, peak particle velocity, structural response
Abstract: Blast-induced ground vibtration (BIGV) velocities and frequencies are of major concern due to their adverse effects and damage to structures. Therefore, it becomes essential to assess the velocities and frequencies induced by blasting in terms of quantitative and quantitative assessment to overcome the problems. There is a need for scientific studies using devices like triaxial geophone associated with a seismograph to measure the peak particle velocity (PPV) and dominant frequency which cause damage to domestic or residential structures near an opencast mine. Each mine has specific geo-mining conditions, and scientific studies provide appropriate results. In total 32 number of blasting data sets were recorded at every 50 m from the blast site to the last observation point near the village. Ground vibration associated damage criteria is defined in terms of the PPV at different frequency levels and the strength of the structures under study. The permissible limits of BIGV have been provided by the Directorate General of Mines Safety, Dhanbad, India. The permissible PPV values of the BIGV in India is 2,5,10 for the historical and sensitive structures, 5,10, 15 for domestic houses and 10, 20, 25 for industrial buildings at <8, 8-25 and >25 HZ dominant excitation frequencies respectively. The recorded dataset has been proposed through standard models. The velocity amplitude versus frequency gives a reliable relationship about damage criteria of structures. The structures study carried out in a mega opencast project provides the basic knowledge to assess the safe distance from blasting site for responsible for more damage to nearby structures and to determine the correlation coefficient between measured and predicted PPV values.

Keywords: Coal mining, computational fluid dynamics, heat stress, underground mines, Ventilation systems
Abstract: Coal mining plays a significant role in the economy of India. The health and safety of miners working in underground mines is a serious concern. One of the risk factors is with regard to the ventilation systems. Computational fluid dynamics is one of the major tools used to study the air-flow distribution. It helps in understanding the blind galleries which may need adequate ventilation. It also helps suppress the spontaneous heating of poorly ventilated workings and in generating heat-stress plots inside the galleries to ensure the safety of mineworkers.
