Subject: Quality assessment of groundwater of Kadapa district, Andhra Pradesh, India for Irrigation purpose and management options.
Keywords: Groundwater quality, ionic correlation, salinity, sodium absorption ratio, spatial variability
Abstract: Water samples collected from various locations in Kadapa district, Andhra Pradesh (AP), India were analysed for quality parameters , namely reaction (pH) , salinity, Ca2+, Mg2+, Na+, and K; CO3-2, HCO3-, Cl- and SO4-2.The pH fell in the range 6.5 -8.1, electric conductivity (EC) from 0.4 to 41.2 (mmol 1-1) ½ adsorption ratio (SAR) from 0.4 to 41.2 (mmol 1-1) ½ and residual sodium carbonate (RSC) from -52.4 to 16.2 (meq 1-1).The presence of positively charged ions, namely calcium, magnesium, sodium and potassium varied from 0.4 to 46.0, 1.2 to 16.4, 0.76 to 60.1 and 0.002 to 11.78 meq 1-1 respectively. The concentration of bicarbonates, chlorides and sulphates varied from 0 to 2.0, 1.0 to 17.6, 0.4 to 76.0 and 0.3 to 14.8 me 1-1 respectively. The dominance of ions for majority of the samples was Na+>Ca2+>Mg+2 >K+ for positively charged ions and HCO3_>Cl_>SO4-2>CO3_ for negatively charged ions. According to classification of irrigation water by the Central Soil Salinity Research Institute, Karnal, Haryana, India, 53.18% water samples is good, 21.88% marginally saline, 0.3% saline, 4.56% high SAR saline, 6.69 % marginally alkaline, 7.90% alkaline and 5.47% highly alkaline. Spatial variability of pH, EC, SAR, RSC and groundwater quality in Kadapa district, AP was demonstrated using GIS maps.

Subject: Tremors and built environment of Hyderabad, Telangana, India: safety of buildings using recorded ground motions
Keywords: Built environment , ground motion, hydroseismicity, microtremors
Abstract: Although the city of Hyderabad in Telangana, India lies in seismic zone II, low to medium intensity tremors that pose a serious concern towards safety of the built environment are not uncommon. One such series of tremors occurred during 13-20 October 2020, in the financial district of Hyderabad and created a panic situation due to perceivable shaking and jolts with loud sounds associated with hydro-seismicity. To understand the safety of the city’s-built environment, a study was conducted on low, medium and tall buildings using ground motions recorded at the International Institute of Information Technology (IIIT) Hyderabad, which is 2.3 km from the epicentre. The amplification of ground motion on the second floor of the Nilgiris Building in IIIT, Hyderabad was 1.2-2.3. The vibrations recorded on the ground floor of the Nilgiris Building were used to develop a site-specific response spectrum. The site was further used to obtain the peak responses of the considered building s through response spectrum analysis. The present study suggests that the low-rise buildings, mid-rise buildings and non-structural elements in high-rise buildings are under threat in the case of high-intensity earthquakes.

Keywords: Fayalite and fluorite granite, magmatism, mineral chemistry, petrography, supercontinent amalgamation.
Abstract: The present study reports fayalite-bearing granite bodies from the Assam-Meghalaya Gneissic Complex of Northeast India. These are weakly peraluminous with high amounts of alkalis and meagre contents of magnesium, calcium, titanium and phosphorus. The chondrite normalized REE pattern is flat, having minor enrichment of HREE with negative europium anomaly suggesting their A-type character. The discrimination based on Rb, Y, Yb, Nb and Sc content indicates their generation due to melting o crustal components. Early crystallized fayalite and fluorite grains indicate that their emplacement in an extensional tectonic setup most possibly represents the final stage of Rodinia Supercontinent amalgamation.

Abstract: The present study explores the pattern and extent of food-crop diversification and its implications on nutritional indicators in India using district-level data for the most recent period. It relied on data from land-use statistics and the National Family Health Survey 2015-16. We estimated the Simpson index for food-crop diversification and under nutrition index for nutritional status. The association of crop diversification and nutritional status was analysed employing bivariate copula function. The findings show striking regional differences in the extent of food-crop diversification and nutritional outcomes. The results of the copula function indicate a significant inverse relationship between crop diversification and under nutrition.

Keywords: Decarbonization, grid interconnection, risk assessment, stochastic weather generators, wind drought
Abstract: Wind power growth makes it essential to simulate weather variability and its impacts on the electricity grid. Low-probability, high-impact weather events such a wind drought are important but difficult to identify based on limited historical datasets. A stochastic weather generator, Imperial College Weather Generator (IMAGE), is employed to identify extreme events through long-period simulations. IMAGE captures mean, spatial correlation and seasonality in wind speed and estimates return periods of extreme wind events over India. Simulations show that when Rajasthan experiences wind drought, southern India continues to have wind, and vice versa. Regional grid-scale wind droughts could be avoided if grids are strongly inter-connected across the country.

Subject: Flow measuring devices in surface irrigation for enhancing agricultural water productivity
Keywords: Agriculture, field channels, flow-measuring devices, surface irrigation, water productivity
Abstract: Judicious use of water plays a vital role in enhancing its productivity in agriculture. In India, surface irrigation covers about 88% of the irrigated area with application efficiency ranging from 0% to 40%. Therefore, it becomes imperative to improve water application efficiency of canal commands and other areas under surface irrigation. Water application efficiency can be improved by minimizing conveyance losses and by judicious irrigation scheduling pertaining to different crops, which can be accomplished by accurate measurement of irrigation water. Measurement of irrigation water supplied to farmlands not only assists in the saving of water but also enhances water productivity in agriculture. The most popular device for measuring irrigation water in field channels is the Parshall flume, which has undergone a series of modifications to simplify its construction, improve the accuracy of measurements and reduce its cost leading to its wider acceptance by the stakeholders. Thus, it becomes imperative to develop an accurate, low-cost and portable flow-measuring device for enhancing agricultural water productivity. Moreover, a review of of the literature reveals limited availability of portable and digital flow-measuring devices for real-time measurement of surface irrigation through field channels. Nonetheless, it is established that the use of flow-measuring devices in surface irrigation will not only save water but also expand the area under irrigation, ensure its sustainability and improve agricultural water productivity.

Abstract: Shifting cultivation (SC) is a system of agriculture widespread in the tropical and subtropical regions of the world. In India, it is rampant in the East and Northeast states.SC has been overwhelmingly portrayed as a threat to ecosystems and climate, ignoring the ecological value of the fallow phase and secondary forests. Finding ways to manage the practice of SC without affecting agricultural productivity is essential for climate change mitigation, biodiversity conservation and the welfare of indigenous communities. This study analyses recent research on the impacts of SC with regard to ecosystem at different stages of the process.

Abstract: The famous South Asian Bronze Age civilization, also known as the Indus or Harappan Civilization that flourished between 3200 and 1400 BC is considered one of the three greatest urban riverine civilizations in the world. The Indus Valley Civilization 9IVC) spread along the Indus River and extended from northeast Afghanistan to north-west India, encompassing a vast area with an ecologically diverse environment. About 1500 Indus sites, ranging from village communities to large cities with thousands of people, were known to exist in the subcontinent. However, in comparison to its wider extent, the true potential of the Indus/Harappan sites is yet to be explored. There is an ongoing debate regarding the cropping pattern and how the ancient societies responded to variable environments and ecological changes during the last 5000-3500 yrs BP 4.6.

Abstract: According to the forestry production and trade database of the Food and Agriculture Organization of the United Nations, Rome, Italy, India Imported US $8.7 and 5.9 billion worth of wood and wood products in 2019 and 2020 respectively. This trend has been increasingly since 1961 (US$ 0.04 billion), keeping pace with economic growth. The small reduction in the 2020 import value does not indicate the much-needed reprieve from exported deforestation elsewhere. According to the Forest Survey of India’s biennial India State of Forest Report 2021, the country has 71.38 million ha area under forest and 9.57 million ha area under tree cover. Further, the Report indicates that increase in forest cover within the recorded forest area (RFA) or green wash (GW) area was 3100 ha, whereas increase in forest cover outside RFA/GW area was 150, 900 has compared to the previous assessment in 2019.

Subject: Numerical analysis of heat dissipation through granite and clay in the multi-barrier system of a geological disposal facility
Keywords: Bentonite, deep geological repository, granite, radioactive waste, thermo-mechanical analysis
Abstract: High-level heat-emitting long-lived verified radio-active waste produced during recycling of the spent nuclear fuel is under consideration for permanent disposal in deep geological formation with appropriate thermo mechanical, hydro geological and geochemical properties. The capability of these rock formations ensuring long-term confinement and isolation of such waste from the environment is significantly controlled by their efficiency in smoothly dissipating he heat emanating from the waste. A number of rock types such a basalt, granite, clay stones, volcanic tuff, argillites, etc. are being evaluated worldwide as well as in India. In this study, granite from Jalore and bentonite from Barmer, both from Rajasthan, India, have been evaluated for their heat dissipation capacity. The study revealed that the temperature within granite at the Centre of the canister reached 55.21°C, resulting in a thermal stress of 25.50 MPa. Bentonite experienced a temperature of 67.42°C in the central part with maximum thermal stress and displacement of 0.997 mm was recorded at the granite-bentonite interface. Thus, no significant microcrack formation or undesirable displacement was observed within the granite as well as in bentonite, suggesting their capability to isolate and confine the heat-emitting source for extended periods.

Subject: Productivity of heat (Tritcum aestivum L) and soil fertility with poplar (Populus deltoides) agroforestry system in the semi-arid ecosystem of Haryana, India
Keywords: Agroforestry, crop growth and yield, Populus deltoides, tree-based intercropping, wheat
Abstract: The diverse and multi-component nature of traditional agroforestry systems 9AFS) provides them a unique edge over monoculture cropping, particularly in arid and semi-arid ecosystems due to their role in providing several ecosystems services (ES) in addition to their prime role in agricultural production. Appropriate selection of components and their management practices results in reduced competition for resources among the components and maximum capitalization of the interactions. Poplar-based AFS adopted in a big way by farmers in the Indo-Gangetic region of India has improved their economic status due to its high industrial value. The present study discusses the effect Populus deltoids as windbreak on yield of wheat as intercrop and soil nutrient status. We considered winter wheat varieties (WH-1105, WH-542, HD-2967, HD-943 and DPW 621-50) during two consecutive years east-west and north-south directions. Whereas effect on crop produce were limited for all wheat varieties with increasing distance from the tree line, considerable yield reductions were found near the tree line (treatments T1 and T2) for all the wheat varieties. The heist available soil N (365.2 kg ha-1), P (19.7 kg ha-1) and K (357.3 kg ha-1) were recorded near the tree line at a distance of 2 m. To optimize the provisioning service of poplar windbreak AFS, the cultivation of highly shade-tolerant wheat variety HD-2967 may be advisable over other varieties towards the end of the rotation of mature poplar trees.

Keywords: Drying time, mint leaves, open sun drying, solar dryer, thin layer drying models
Abstract: Thin layer drying behaviour of mint leaves was experimentally studied using a domestic, direct-type, natural convection solar drying unit and compared with traditional open sun drying. The experiments were conducted in Bengaluru (12.96°N, 77.56°E), Karnataka, India and the effect of various parameters on drying was studied. Drying time using the solar drying unit was compared with traditional open sun-drying. Reduction in drying time was found using the solar drying unit compared to open sun drying. After 10 h, the moisture in the mint leaves was observed to reduce from 93% to 8.33 % in the solar drying unit and to 26.6% under open sun drying conditions. The drying data were analysed and curve fitting was done using five thin layer drying models. Among these models, logarithmic model for solar drying unit and the Henderson and Pabis model for open sun drying were found to satisfactorily describe the drying kinetics of mint leaves.

Subject: Experimental and numerical free vibration analysis of industry-driven woven fibre laminated glass/epoxy composite beams
Keywords: Finite element analysis, free vibration, laminated composite beam, modal behaviour, natural frequency
Abstract: The present study involves frequency-driven exploration of bi-directional, industry-driven, laminated composite glass/epoxy beams by experimental and finite element analysis. The experimental vibration responses were ensured through a vibration first Fourier transform (FFT) analyzer. The finite element predictions were made using MATLAB platform by developing a programmable computer code accounting for shear deformation. The results conclude that the free-vibration finite element predictions for glass/epoxy beams are sensitive to effects of different boundary conditions and span-to-thickness ratios. The present study will assist in our understanding of modal behaviour towards design and service of laminated beams in the frequency domain and can serve as experimental benchmark results.

Subject: Identification of fresh groundwater areas in the Central Godavari Delta region, Andhra Pradesh, India-an integrated approach
Keywords: Delta regions, electrical conductivity, fresh groundwater zones, geomorphology, vertical electrical sounding.
Abstract: Groundwater is vital and dependable source of water for drinking, agriculture and industries. The central Godavari Delta of East Godavari district, Andhra Pradesh, is composed of alluvium wherein fresh and saline pockets exist together in close proximity. The present study is to identify freshwater pockets using geomorphological. land-use/land-cover, geophysical and geochemical analysis. Groundwater samples are analysed for electrical conductivity which revealed that about 35% of area i occupied by freshwater pockets in the northwestern and eastern parts. Vertical electrical sounding data inferred that resistivities less than 5 ohm-m is clay and 10-75 ohm-m corresponds to freshwater zone. Freshwater pockets at depths greater than 8 m observed in northern part and shallower depths in southern parts. This integrated study proved successful in identification of fresh groundwater pockets in the delta region.

Subject: Gradual sustainability approach for urban transport through subtle measures
Keywords: Metro station, sustainability, traffic simulation, urban transport, vehicular emission
Abstract: Capacity enhancement and demand reduction are the two the most approaches considered to deal with increased congestion in urban areas. The first approach involves construction of various infrastructure for providing increased capacity for motorized vehicles, whereas the second approach includes restricting movement of road users from congested areas(s). Experiences from the across the world have demonstrated that both the approaches have failed to resolve the problem of congestion. The present study has been carried out to assess traffic characteristics around five metro (rail) station areas in New Delhi, India, to examine the effect of subtle changes towards improvement for all road users. The impact of alternate traffic circulation plans, based on various traffic management strategies around these metro stations, has been compared using microscopic traffic simulation. The study has clearly demonstrated that parking related policies (including segregated parking lanes for cycle rickshaws and electric rickshaws) can result in improvement in vehicular speed by 2 to 6 km/h in the influence of zone of the selected metro stations for all categories of motorized vehicles. This is expected to result in total daily savings of 593 litres of petrol, 103 litres diesel and 643 kg CNG, and total CO2e (equivalent) reduction of 3.5 tonne/day in all the five metro stations. IT is evident that the sustainable scenarios (viz.segregation/shifting of on-street parking, signal design, etc) or similar those that have been suggested, would result in significant reduction in fuel consumption and corresponding CO2e (equivalent) emissions. Implementing agencies can choose the scenario best suited to them, among the given options.
