Subject: Study of steel mass spring system with varying speeds in a tunnel
Keywords: Floating slab track, mass spring system, natural frequency, tunnel, vibration
Abstract: A steel mass spring system (MSS) has been designed using the Zimmermann method. The impact of speed on the curve radius, cant, stiffness, static and dynamic deflection of the MSS is observed and the natural frequency of the system is calculated. It has been observed that the sped of the train affects the stiffness of MSS and therefore the insertion loss. As the speed of the train increases, the characteristics length of the floating slab track decreases due to which the spacing between MSS also changes. Hence this design of MSS will be effective.

Keywords: Cloud computing platform, curve number, river basin, rainfall-runoff modelling, water resources
Abstract: The capability of open-data sources in cloud computing was explored in rainfall-run-off modelling through the Soil Conservation Services curve number (SCSCN) model. The Google Earth Engine (GEEE) has a petabytes catalogue of global remote sensing and GIS datasets, numerous functions and algorithms to manipulate and visualize datasets rapidly. In this study, an algorithm has been developed to prepare dynamic CN maps in GEE using Open Land Map Soil Texture and MODIS land use/land cover (LU/LC) data through ternary function and climate hazards group infrared precipitation rainfall collection for input rainfall and creation of antecedent moisture conditions. The capabilit8ies of the developed algorithm were demonstrated for Shipra, Kuttiyadi and Bah river catchments in India. However, it can be used with different satellite data for estimating the run-off and impact of LULC change on run-off for nay part of the world any desired period. The developed algorithm not only utilizes GEF and the public archive database for estimating the run-off at basin/subbasin scales for the planning of water resources, but also provides a quick evaluation of the impact of LULC change on run-off over time.

Subject: Variability of ionospheric total electron content at low-latitude station during twin solar maxima and solar minima of the 24th solar cycle and its comparison with different versions of IRI models.
Keywords: Geomagnetic storms, Ionosphere, low-latitude station, solar cycle, total electron content
Abstract: In this study, we compared the modelled total electron content (TEC), i.e. ionospeheric TEC derived from the latest International Reference Ionosphere (IRI) versions (viz.IRI-2007,IRI-2012 and IRI-2016) with TEC derived by the International GNSS Service (IGS) receivers at a low-latitude station, namely Pathum Wan, Thailand (code-CUSV;lat.13.74°N, long.100.54°E) during the twin solar maxima 2012 and 2014, and the solar minima 2017 of the 24th solar cycle. We observed that the modelled TEC results were slightly underestimated than those derived by global positioning system (GPS), during the maxima and minima periods. It was also observed that the modelled TEC and GPS TEC followed a similar sinusoidal pattern with crests in the equinox months and troughs in the solstice months. We calculated standard deviation of the modelled TEC from the corresponding GPS TEC during the period. The study shows that the IRI model is more suitable when applied during solar minima period. We also carried out correlation study between modelled TEC and GPS TEC and obtained a moderate degree of positive correlation. Thus, we can conclude that IRI-2007 is the most suitable version for the twin solar maxima and the minima periods. Also, IRI-2016 is the most suitable model for TEC estimation during geo-magnetic storms.

Abstract: Large-scale and long-term baselines on climate-sensitive phenology of widespread tree species are lacking in the Indian subcontinent. Citizen scientist can help bridge this information gap by contributing simple, technology-based data. Here we describe an India-wide initiative called Season Watch, with preliminary insights into contributor behaviour and species phenology. Between 2011 and 2019, cumulative contributor numbers have increased every year, although consistent contributions remain constant and low. We describe seasonal and spatial phonological patterns in most-observed species based on repeated monitoring and one-time’bioblitz’events. We study in detail the flowering phenology of one particular species, Cassia fistula, which appears top show aberrant pehnoloy, reflecting a potential shift away from culturally known flowering dates. We conclude that citizen science-contributed information can be a valuable reference database to compare future changes in tree phenology.

Abstract: Mountain roads are important lifelines and the most critical means for connectivity in the Himalayan villages of India. However, the inherent geological, geomorphological, ecological and climate fragility of the terrain warrants critical scientific investigations for the roads to sustain the vagaries of nature. Further, the increased frequency of extreme events with the ongoing climate change increases the potential impact of disasters. This note highlights the major challenges and issues faced with the ongoing road-widening projects in the country. It cautions against the uniform standard of road widening and the need to increase sensitivity towards appreciating the terrain fragility.

Abstract: The Peafowl (Pavo cristatus), Jackal (Canis aureaus) and giant honeybee (Apis dorsata) colonies in rural areas of Palakkad district, Kerala, part of the southern Western Ghats of India, have changed significantly due to ecological imbalance. Nowadays, there are more peafowl, and no jackals are spotted in the area giant honeybee colonies are also rare. This may be due to human activities such as agricultural expansion, the use of agro-chemicals, construction activities, urbanization and loss of vegetation. These factors may have led to habitat loss, which has affected the ecological balance ultimately affecting the population of these species. Ecological restoration can help regulate the population of these species. There is a need for detailed scientific studies and expert intervention to address this ecological imbalance and population changes of these species in the study area.

Abstract: According to the World Health Organization (WHO), around 10-20% of adolescents worldwide suffer from mental health issues, and this is rising now. It has also been proven that half of all mental health problem develop by the age of 14. Potential causes for this include social and economic compulsions which result in children living with their parents for an extended period of time, thereby delaying the sense of autonomy in them, social media influences and the difficulties of modern school culture.

Keywords: Molecular taxonomy, morpho-taxonomists
Abstract: Floras are documented accounts of plant species occurring naturally in specific regions with defined or loose boundaries. These documentations are generally accomplished for specific groups and not for all plant groups collectively, although the word ‘flora’ is indicative of all groups together. They appear either as soft versions (e-floras/PDFs) or in hard copies such as book volumes or books. Taxonomists associated with different herbaria/institutions usually author them. The systematic arrangements/classification s that gets admittance in the organization of these floras are largely those adopted by herbaria/institutions to which they are associated. Since the founding fathers of Indian seed plant taxonomy were primarily the British, many floras published in the late 19th and early 20th centuries for the Indian subcontinent/India/erstwhile provinces had adopted the Bentham and Hooker classification, a system detailed in Genera Plantarum (1862-1883).

Abstract: An experiment was carried out to study the effect of different essential oils on enzymatic activity of stored oyster mushroom (Pleurotus florida).The harvested fruiting body was treated with four essentials oils ,i.e. lemongrass oil, citronella oil, mint oil and clove oil at two different concentrations-5 and 10µl-to test the total phenol content (TPC) and activity of three important enzymes, viz. phenylalanine ammonia lyase (PPO) that are involved in post-harvest quality preservation of mushroom.TPC (0.286mg/g), PAL content ( 0.038 µM/g) were found significant in mint oil treated mushroom at 10µl concentration.TPC and PAL content were higher in essential oil-treated mushrooms compared to the control samples, whereas PPO and POD contents were lower in the treated samples, signifying that essential oils treatment had a positive impact on the quality of harvested mushrooms. This preservative technique will help in increasing the shelf-life of harvested fruiting bodies.

Subject: Ecosystem services from ravine agro-ecosystem and its management
Keywords: Ecosystem services, gullied land, livelihood, participatory management, ravines
Abstract: Ravine agro ecosystems are characterized by degraded gullied lands formed over the years due to several natural and anthropogenic factors, surrounded by the adjacent table lands cultivated for the production of food and fibre for humans and livestock. These potential lands not only support the livelihood of marginal and smallholder farmers but are host to various plants and grass vegetation providing a cushion to the local environment. A two-way relationship exists between the human settlements and ecosystem services in these agro-ecosystems. While the ravines support plants, grasses and human settlements in these agro-ecosystems, the same biophysical pressure over time degrade the ecosystem leading to ecosystem services loss, if not managed sustainably. The present pilot study conducted in the Mahi ravines, Gujarat, India, has examined these issues from the local socio-ecology perspectives and suggests management options for participatory management.

Abstract: Land degradation neutrality (LDN) adopted in 2015 as target 15.3 of sustainable development goals (SDGs) is a challenge as well as opportunity in the present world to restore the degraded lands. Soil and water conservation (SWC) techniques in the form of bio-engineering measures have vast potential to attain LDN in sustainable manner. India has already announced a LDN target of 26mha and is fully determined to meet the target by 2030. Therefore, this article proposes and recommends incorporation of SWC measures in effective ways at policy level as key to the success of LDN.

Abstract: Climate change has been influencing bird species in different ways, some documented changed include education in geographic range, decline in abundance and changes in the seasonality of migratory bird species in spring after overwintering in the tropics. We undertook a study on two species of high-elevation dependent, restricted-range flycatchers: Black-and-orange flycatcher (BOF) Ficedula nigrorufa (Jerdon, 1839) and Nilgiri Flycatcher (NIF) Eumyias albicaudatus (Jerdon, 1840), to determine how they respond to the predicted climate change scenarios. We used 94 and 300 independent occurrence points for BOF and NIF to develop climate models and understand the species responses to climate change scenarios using MaxEnt algorithm. We also used isothermality, mean temperature of coldest quarter and slope for developing BOF model. For NIF, we used isothermality, mean temperature of coldest quarter, precipitation of driest month, precipitation of warmest quarter, slope and enhanced vegetation index. The mean temperature of coldest quarter (BIO11) was the most crucial variable influencing climate suitability for both the species. The model predicted the current extent of occurrence of 6532 sq.km as suitable for BOF and 12,707 sq.km for NIF, within their ranges. However, only 27% and 24% of the existing suitable area of BOF and NIF respectively, falls within the protected area network in the Western Ghats. Future predictions suggest suitable area loss to the tune of 20-31% for BOF and 36-46% for NIF by 2050.

Abstract: Flacherie is a major bacterial disease causing >40% loss during Muga summer crops. For finding the root causes of the diseases, relationships were established between rearing and production data corresponding to land use/land cover, land surface temperature and meteorological parameters. Adverse effects were found in farms associated with anthropogenic activities, in contrast to forest cover which shows a negative trend. Muga disease early warning system, a mobile-based application and dashboard has been developed to predict rate of flacherie infestation at least 5-10 days in advance, for proper precautionary measures by the farmers to avoid disease outbreak and crop loss.

Subject: In silica plum pox virus silencing via host-retrieved miRNAs in peach plant
Keywords: miRNAs, peach plant, plum box virus, yield loss, target prediction algorithms
Abstract: Peach (Prunis persica) is a deciduous, edible, stone fruit producing plant, belonging to the family Rosaceae. The plant is prone to various pathogens and one of them is the plum pox virus 9PPV). This is a lethal virus of peach plant causing pox disease of plum. Its attack results in 83% -100% yield loss in highly susceptible varieties of peach plant. The complete genome of PPV is 9791 base pairs with positive-sense single strand. The full-length genome of PPV encodes a large poly-protein initially, which cleaves proteolytically into ten mature proteins-coat protein, helper component proteinase,P1,P3, viral genome-linked protein,6K,6K2, cylindrical inclusion protein, cylindrical inclusion protein b and NIa-proprteins. The objective of this study is to identify such sites in the PPV genome which can be targeted by PPV-derived miRNA through target prediction computational tools/algorithms. A total of 214 mature miRNAs were chosen from the miRNA database to check their complementarity with the PPV genome. Minimum free energy, folding energy, seed pairing, target-site accessibility, pattern recognition and multiple target sites were the parameters considered for target prediction algorithms. Two out of 214 miRNAs were predicted as potential against plum pox virus by three of four tools used for target prediction. Thus, the results encourage generating transgenic, PPV-resistant peach plants by expression of predicted miRNAs.
