Subject: Uncertainty analysis using Monte Carlo simulation and rock physics modelling to explore subsurface properties of Krishna–Godavari Basin, India
Keywords: Log facies, reservoir, rock physics modelling, simulation, uncertainty analysis.
Abstract: One of the main challenges in reservoir characterization
is the accurate prediction of lithology and saturation
heterogeneities. In this study, a methodology has been
developed that combines Monte Carlo simulation (MCS)
and rock physics modelling (RPM) to explore subsurface
properties and characterize reservoirs of the Krishna–
Godavari (KG) Basin, India. RPM and MCS were effectively applied to well-log data in this study to discriminate
distinct lithologies and fluid types, as well as uncertainty
analysis. Various diagnostic models, such as the contact
cement model, constant cement model and friable sand
model, were used for this purpose. The cementation of
reservoir sand ranged from 1% to more than 4%, according to the analysis. The gas sand reservoir, cap
shale and brine sand were categorized using a rock
physics template (RPT) model built over VP/VS against
the AI cross-plot. Gas saturation was appropriately indicated by the RPT model produced from the shallow
marine environment. The present study proves that
RPM developed in the first part of the study may be
used to perform uncertainty analysis using MCS. We
simulated three different lithologies in this study, viz.
shale, brine sand and gas sand, and then categorized
them using VP/VS versus P-impedance cross-plot.

Subject: Impact of climate change on agriculture ecosystems and resilience for sustainable development under the Global Framework for Climate Services in India
Keywords: Agroecosystems, climate change, food security, remote sensing, sustainable development
Abstract: Agriculture is affected due to the impact of climate
change on soil, land, water and the atmosphere. Agriculture is also a significant contributor to greenhouse gas
emissions, directly or indirectly. The challenge lies in the
reduction of emissions without impacting food production and yield. With the increase in air temperature
and extreme events of rainfall as the probable indicators
of climate change, there can be impacts on various components of the agroecosystem, which include crop yield,
soil quality, pest and disease infestation, crop loss, irrigation water demand, etc. This will, in turn, impact food
security. The development of novel adaptation techniques
and strategies for agriculture and surveillance of resources is needed to tackle the adverse effects of climate
change. This article discusses the impacts of climate
change on various components of the agroecosystem
and how to achieve resilience for sustainable development. Various national-level programmes for climate
change resilience in agriculture have been implemented
in India to incorporate climate information into agricultural development by integrating climate services into
practices and policies for future food security

Subject: Unknown urban cavities – formation, problem and possible mapping
Keywords: Cavities/sinkholes, mapping, soil density, subsurface flow, urban living.
Abstract: Urban living captivates the younger generation due to its wealth of prospects and attractive lifestyles. However, it is important to acknowledge that many familiar and unforeseen challenges accompany urban living. This study discusses the most pressing issue of the collapse of urban roads due to
the formation of cavities/sinkholes on the subsurface, with scientific reasons and advanced approaches
to mapping such cavities in order to reduce urban risk. Sinkhole formations are common in many
cities in India, and several such incidents are being reported. Naturally formed sinkholes in lateritic
deposits and urban cavities are due to improper handling of the subsurface soil. Typical reasons for
the formation of urban cavities are summarized here with scientific explanations based on the density of
filling and subsurface water flow. Further, scientific techniques available for identifying such cavities in
advanced geophysical methods and the usual procedure for closing these cavities are presented.
Regular inspection to focus on the triggering cause and comprehension of the underlying causes and
technically designed treatments based on site soils can help prevent cavities from collapsing and
subsequent disasters

Keywords: Earth and space science, geomagnetism, public outreach programme, research organizations, young students
Abstract: Conducting public outreach activities for students and the general public has been an integral part
of several research organizations. It is a way to communicate with common people to make them
aware of the research work at any institution. However, the COVID-19 pandemic affected these activities. Even during the post-pandemic period, the response to public outreach programmes has been
poor. To deal with this situation, an initiative called ‘Reach the Unreached’ has been implemented
at the Indian Institute of Geomagnetism (IIG), Navi Mumbai, which has helped boost participation
in public outreach activities. This low-budget programme has been well-received by many schools.
Moreover, it is found to be an effective way of reaching a large number of students. In this article,
we share our post-COVID-19 experiences and information about different programmes implemented
by IIG to reach a maximum number of people with basic concepts in the field of space science and
geomagnetism, and their applications. The public outreach team of any institution must be energetic
to adopt and implement different methods to attract and motivate young minds. The experience
shared in this article will be useful to public outreach teams from other institutions.

Subject: Geoscience education and workforce development for energy transition
Keywords: Geoscience education, workforce development, energy transition
Abstract: Driven by the gravity of global warming
and the need for national resilience against
disruptions in resource supply chains
, the
transition from today’s fossil fuel-dominated
world to a low-carbon world with environment-friendly and secure energy supplies
is at the forefront of public and policy debates, research and development (R&D)
and international attention. This would necessitate an increase in the number of geoscience graduates who provide critical
knowledge and skills for exploring and
developing energy resources. However, according to the 2022 Geoscience Currents, a
report published by the American Institute
of Geosciences, student enrollment and
graduates in geoscience programmes have
sharply declined in recent years3
. This decline is partly related to the COVID-19
pandemic but largely due to a slowdown in
the oil and gas industry, which has historically hired a vast number of geology and
geophysics graduates. The employment of
geoscience graduates in the oil and gas industry has decreased from 40% for undergraduate and 70% for postgraduate degree
programmes in 2013 to merely 6% in 2020
for both groups. As a result, many universities in the US and Europe have closed
their petroleum geoscience and engineering programmes.

Abstract: Escherichia coli and Klebsiella species are
major human and animal pathogens that
produce broad-spectrum antibiotic resistance. Antibiotic resistance spreads rapidly,
owing mostly to horizontal gene transfer
across populations of competent bacteria,
i.e. from faecal germs to environmental
isolates or vice versa
. The horizontal gene
transfer approach is well recognized for
producing extended spectrum beta-lactamases (ESBLs), which are resistance determinants and have clinical value in the
family Enterobacteriaceae, particularly Klebsiella pneumoniae and E. coli2

Subject: Toxic effects of Triazophos pesticide on male and female fied workers in Guntur district, Andhra Pradesh.
Keywords: Pesticides, Triazophos, Field workers
Abstract: Indian being an agricultural land, pesticides consumption causes a serious environmental and public health problem. Due to the steep competition and a large demand, many farmers are resorting to extensive and rather overuse of organophosphate pesticides to increase their agricultural yields.The workers who are involved in the spraying activity and mixing of pesticides in the fields get the direct exposure to pesticides due to unsafe and non-preventive work practices. They do not use the safety masks, gloves and other protective gears during the spraying of pesticides which results int other access of pesticides in the blood steam through inhalation and dermal exposure which can adversely affect their eyes, skin and respiratory system. Triazophos is a broad spectrum systematic insecticide and acaricide belongs to class organophosphorus pesticides. It is widely used in cotton, chillies and rice crops.

Abstract: The present study investigated the efficiency of biochar prepared from peels of sweet lemon (C.limetta) for removing chromium (Cr) from tannery effluent by the process of adsorption. The adsorbent was used in the form of biochar and was characterized by SEM-EDXA and FTIR studies. The study was carried out in batch experiments to investigate the effect of different dosage of adsorbents at different time intervals at constant pH and temperature. The saturation point was found to be 0.5 gm/100 mL of tannery wastewater at 200 min of contact time with maximum removal efficiency of about 98%. The presence of different functional groups and morphological change on biochar enabled the efficient removal of chromium. Further, the adsorption of chromium onto the surface of biochar of the peels of sweet lemon favoured Langmuir adsorption isotherm in comparison to Freundlich adsorption isotherm, which demonstrate that the adsorption process has been monolayer and homogenous.

Abstract: Pavements on black cotton soils fail during adverse weather conditions due to swelling and shrinkage characteristics of such soils, Stabilization of black cotton soils, therefore, becomes mandatory. Geosynthetics are soil stabilization materials used to improve soil conditions in various applications. Cash ash is available at low cost and it is utilized for the stabilization of black cotton soils. The present study aims to utilize coal ash effectively in pavement subgrade. In phase of the research, index and engineering properties of virgin soil is studied, and the soil is classified under CH (clay of high compressibility) category. Coal ash is added to the soil by10%, 20%, 30%, 40%, 50% replacements to the weight of soil. The shear strength of virgin soil is 90.60 mN/m2 at an optimum moisture content of 21% and maximum dry density of 1.6807 g/cc. The california bearing ratio 9CBR) values of the virgin soil under soaked and soaked conditions are 5.33 % and 2.84 %, respectively. This study shows that the shear strength, optimum moisture content, maximum dry density is maximum at an optimum of 10% addition of coal ash to the soil. Atterbergs limits and plasticity index decreases with the addition of coal ash.

Abstract: According to National thermal power corporation (NTPC) reports, in the NTPC Unchahar power plant in Raebareli district started generating power in 1988 with five units of 210 Mw each, an extremely high-pressure explosion occurred because of ash within the boiler furnace caused it to leak, producing a disaster. The blast was reportedly triggered in the duct connected to the boiler which is used for transferring ash of burnt coal. It is believed that the ash pipe got choked, leading to the blast. The boiler pipe burst in the 500 Mw power generating unit that started operating in March at the plant in Unchahar, which is nearly 30 years old. A massive fire broke out and a huge ball of dust rose after the explosion, making rescue difficult. According to NTPC reports, there was sudden abnormal sound at 20 m elevation and there was an opening from which hot flue gases and steam escaped affecting the people working around the area. This paper highlights the importance of boiler tube leakage on the performance of the thermal power plant. This paper also suggests various controlling mechanisms towards enhancing energy efficiency in thermal power plants.

Abstract: The present study evaluates the removal of heavy metals, like lead, cadmium and mercury with varying concentrations of turmeric leaves and stem as adsorbent from the synthetic waste-water. Synthetic wastewater was prepared using lead acetate, cadmium chloride and mercuric chloride at a concentration of 10 mg/L (10 ppm) separately in double distilled water. Varying concentrations of turmeric leaves and stem (50, 75 and 100 mg/ of wastewater) was effective in removing heavy metals, like lead, cadmium and mercury ranging from 35-82% as evidenced from the analysis of treated water by atomic absorption spectrophotometer. The results point out the efficacy of the turmeric leaves and stems as good candidates thereby opening up new vistas in the treatment of wastewater using adsorbents.

Subject: Removal of organic pollutants from coffee wastewater : A mini-review
Keywords: Coffee processing wastewater (CPWW), organic pollutants, treatment technologies
Abstract: The coffee industry utilizes large quantities of water during the various stages of the production process. Consequently, the amount of wastewater generated is high that contains high concentrations of organic matter, nutrients, suspended matter and highly acidic. The effluent discharged unwisely into nearby natural water bodies which flow into rivers and/or infiltrate into groundwater become the main threat to the quality of surface and ground water. Hence there is a need to curb this problem through innovative and eco-friendly techniques. Understanding the coffee processing and nature of the coffee processing wastewater is fundamental for the design and operation of appropriate and effective treatment technologies. This review presents the various treatment techniques adopted and also various research conducted on the removal of organic pollutants from coffee processing wastewater (CPWW). In addition, the scope for biogas production from the wastewater treatment is highlighted.

Subject: Pyrolysis temperature effects on yield, physico-chemical characteristics of pine-bark biochars and cadmium sorption
Keywords: Biochar, cadmium sorption, human faecal, pine-bark, pyrolysis temperature
Abstract: Globally, tonnes of bark wastes are disposed of by timber production industries annually. Pyrolysis of the bark could be viable waste managemnt option where the biochar could be used as sorbents of pollutants in wastewater and in agricultural applications, depending on their properties that are known to depend on carbonization processes. The objective of this study was to determine the effect of pyrolysis temperature on yield and physico-chemical characteristics and cadmium sorption of biochars carbonized from pine-bark. The biochars were produced by slow pyrolysis at 350˚C, 550˚C and 650˚C and were analysed for yield, ash content, fixed carbon, total carbon, nitrogen, and hydrogen content and surface characteristics. Sorption of cadmium was studied using a laboratory batch experoment with the three biochars with solutions of increasing cadmium concentrations. The adsorption data were fitted in best fitting Langmuir isotherms. Biochar from pine-bark showed a more porous structure when pyrolysis temperature was increased. Sorption capacities increased with pyrolysis temperature. The findings imply that pine bark biochar could be a low-cost adsorbent from cadmium from wastewater and the effectiveness could be increased by higher pyrolysis temperatures and furthermore, cadmium sorption efficacy of pine-bark may be improved by incorporation of human faecal waste derived biochars.
