Abstract
Nkoteng-Elap, a hamlet in the Central Region of Cameroon (Central Africa), has water issues, particularly with access to drinking water. The current study aims at (1) mapping the fracture networks of aquifers in the conceptual hydrogeological model and (2) delimiting the groundwater potential zones of the study area. A study combining remote sensing and geoelectrical measurements was carried out along profiles sub-perpendicular to the elongation of the geological bodies. Borehole and field geology data were used to validate the results obtained. The findings point to more than 300 linear structures about 0.065-74.89 km long, with two main directions: N80-100°E and N30-50-70°E. According to the Electrical Resistivity Tomography approach, there are three (03) geoelectric levels: conductive (less than 500 Ωm), semi-resistive (6500-12500 Ωm). resistive (more than 12500 Ωm), and resistant intrusive body (2050 Ωm). Existing drillings display three main lithological formations: the alteration zone, the fissured/altered zone, and micaceous quartzite. The correlation between the ERT data and drilling data reveals that the fissured or altered zone observed at 50 m is potentially aquifers. This structure is characterized by medium resistivity values (6500 Ω.m), flow rates of 1 to 3 m3/h for positive boreholes, and by low resistivity values (500 Ω.m), flow rates less than 1 m3/h for negative boreholes. The final map is categorized into five classes: very good, good, moderate, poor, and very poor groundwater potential zones. These results can help find basement aquifers and be useful in the planning and management of groundwater resources in a meta-sedimentary context.

Abstract
Twenty-one groundwater samples were picked up from the southwest of El Minya Governorate, Egypt. These samples’ physicochemical characteristics were analyzed. Using a water quality index software (WQI) and the United States Salinity Laboratory (USSL) staff chart, water samples were assessed for drinking and irrigation applications. The interaction between water and rock was assessed using the saturation index (SI), chloro-alkaline indices (CAI), Gibbs ratios (GC and GA), end-member diagram (END), corrosion ratio (CR), factor analysis, and dendrogram. Datasets elucidated that water samples were distinguished by SO42-, Na+, and Cl- dominance, excessive mineralization, hardness, and fresh to slightly saline water. The examined water is divided into two types: SO4. Ca-Cl. Mg (30%) and SO4. Na-Cl (70%). All samples were over-saturated with anhydrite, aragonite, calcite, dolomite, and gypsum minerals except for halite and sylvite minerals dissolution, according to SI. The existence of reversible ion exchange between alkaline earth’s (Ca2++Mg2+) ions in water and alkalis’ ions (Na++ K+) in solids; this is explained by the negative values of the chloro-alkaline indices, which point to recharging from rainfall. The Gibbs diagram showed that the dominant interaction is rock weathering. The silicate weathering and evaporite mineral dissolution control the water composition and salinity, which led to an excess of the dominant ions, as demonstrated by the END. Three wells in the research area are potentially unhealthy and unfit for irrigation and drinking.

Published: June 2024

Abstract
Soil erosion is a severe and rapidly rising issue in many parts of the world due to human activities such as farming practices, land excavation for development and deforestation. Moreover, it can negatively impact water availability, agricultural growth, and ultimately, countries’ long-term economy. A quantitative and consistent land degradation assessment is vital for proper planning of soil conservation activities in a catchment or watershed. The Universal Soil Loss Equation (USLE) model is applied in this study to address the issue of soil erosion in the Machhu-sub watershed (24769.63 ha), located in Saurashtra, India. The landscape feature of the study area includes basalt type rock and water body. In this USLE model study we have used input parameters such as rainfall erosivity (R), soil erosivity (K), cover management (C), slope length and steepness (LS), and conservation practice (P) integrated with Geographical Information System (GIS) to analyze and obtain the estimated annual soil loss. Results indicated that the overall soil loss in the study area can be classified into five categories: Very Low (0-1), Low (1-3), Low moderate (3-5), Moderate (5-10), and High ( &gt;10 tons/ha/year). The finding includes the overall soil potential loss of the Machhu sub-watershed is 14.90 tons/ha/year. Furthermore, 60.86 % of the agricultural area is affected by soil erosion. Therefore, the necessary soil conservation methods can be planned in the Machu-sub watershed area based on the USLE analysis. These findings may assist researchers, scientists, and policymakers in building a concrete strategy for sustainable development of not only study area but other catchments also.
Depositional Architecture of a Neoproterozoic Clastic Shelf: Clue from the Owk Shale Formation, Kurnool Group, India
Authors: Barkat Rasikh , Chakraborty Partha Pratim 
Published: June 2024

AbstractProcess-based facies and facies association analysis from the Neoproterozoic Owk Shale Formation, Kurnool Group allowed identification of seven facies types, grouped under four facies associations viz. (i) Greenish grey shale without sand interbed, (ii) Grey shale with thin fine sandstone/siltstone interbeds (iii) Grey shale interbedded with HCS-bearing sheet sandstone (iv) Coarsegrained sandstone interbedded with reddish brown shale. A shallow-marine setting ranging from outer shoreface to distal shelf set-up is interpreted. From facies succession analysis, a steady progradation is documented in course of Owk shale depositional history whereby distal shelf shale is successively overlain by the mid, inner shelf shale and finally by outer shoreface succession. Stacked decimeter-thick progradational depositional cycles (demarcated by mid to inner shelf transitions) constitute the progradational depositional motif. The Owk shelf was storm influenced, though from restriction of storm features within the inner shelf deposit, it is argued that no large-scale coastal set-up occurred at the Owk coastline in course of storm events. Instead, a low to moderate offshore-ward pressure gradient is inferred with coriolis effect that possibly hindered active sediment transport in the distal part of the Owk shelf.
Factors Influencing the Sand Production in the Lakwa Oilfield of Upper Assam Basin, India
Authors: Gogoi Aditi , Borgohain Pradip 
Published: June 2024

Abstract
Sand production is a crucial concern of the Lakwa oilfield of the Upper Assam (India) basin as it develops numerous issues related to oil and gas production. Sand production from oil wells has a negative impact on the economy of oil production since it can harm both surface and subsurface equipment as well as impair the well productivity. The main objective of this paper is to know the various reasons causing the sand production in the Lakwa oilfield of the Upper Assam Basin. Porosity evaluation, grain size analysis, rock-thin section analysis, scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis have been employed to evaluate the mineralogical constituents and their textural variations to find out the facts behind the sand production of Lakwa oilfield. The analyses show that the studied reservoir sandstones are matrixdominated, quartz-wacke type and have poorly sorted texture. The porosity value ranging from 21.4 % to 24.55 % indicates a sand production problem within the rock. The grain size analysis shows that the sandstones are fine-dominated and represent 52.24 to 61.32 % of the total volume. The recorded clay minerals are kaolinite, illite, smectite and chlorite. Feldspars are reported to alter into clay minerals under SEM analysis. The dominance of fine-grained minerals with clay within the rock is the main reason for the sand production in the wells of the Lakwa oilfield. Moreover, the migratory nature of clays in presence of water makes them more susceptible to get loosened and disintegrate, thereby making sand and clay mobile and hence affecting the cementation of the sandstone.
Remote Sensing and GIS-Based Accuracy Assessment of LULC Map and Landslide Susceptibility Prediction for Meghalaya, India
Authors: Naveen Badavath , Sahoo Smrutirekha 
Published: June 2024

ABSTRACT
Through this study, a Landslide Susceptibility Map (LSM) has been developed for the Meghalaya state, India using an Analytical Hierarchy Process (AHP). According to a 2012 Geological Survey of India report, the annual average number of landslides in Meghalaya is nearly 30, which is due to a combination of mountains, steep slopes, and excessive rainfall, leading the state to suffer a huge loss of life and property from landslides. For effective management of the current landslide situation, information about prior landslides is needed. Therefore, the landslide inventory map is prepared with 380 previously occurred events. The Landslide inventory records were separated into training samples (70%) and testing samples (30%) for the purpose of validation. In this regard, the present study has 15 conditioning factors, i.e., slope, rainfall, elevation, relative relief, aspect, distance from the road, curvature, distance from the stream, LULC, lineament density, geomorphology, geology, NDVI, MSAVI, NDWI, which are used to develop susceptibility map. Classification and accuracy assessment of LULC is carried out with segregation as 77% vegetation, 16.4% range land, 3.1% built area, 2.8% crops, 0.4% waterbodies, and 0.3% others (bare land, flooded vegetation, etc.). The Kappa for LULC categorization is 0.92, which is quite satisfactory and suggests that the LULC categorization is reliable. The developed susceptibility map is classified into four different classes, low susceptibility (35%), moderate susceptibility (41%), high susceptibility (20%), and very high susceptibility (4%), and has been verified using physical and Receiver Operating Characteristics (ROC) techniques. Results show that anticipated susceptibility classes are in good match with previous landslide events. The prepared map is reliable and can be used for land-use planning of the state in the future.

Published: June 2024

ABSTRACTHere we report numerous fossil forms of the Ediacaran Flabellophyton genus in the Sonia Sandstone of the Jodhpur Group, Marwar Supergroup, in India. They are assigned as Flabellophyton lantianense, Flabellophyton stupendum, and Flabellophyton typicum species and have been found to have both positive and negative reliefs on the bedding planes of medium- to fine-grained sandstone in the Sursagar region of Jodhpur district. The thallus of Flabellophyton lantianensis occurs in straight to slightly curved and slender forms, is closely packed, and may have thin filaments. The Flabellophyton stupendum is a conical or fan-shaped thallus containing thin bundled filaments and has a discoidal holdfast with a well-differentiated stipe. The Flabellophyton typicum species typically has a thallus with an intermediate conical shape, a globular holdfast with an acute stipe, and a fan-shaped form with bundles of thin filaments. These studied Flabellophyton fossil assemblages are well comparable to those found in South China and South Australia in their conical or fan-shaped morphologies and holdfast structures (mostly found in F. stupendum and F. typicum species) with fine and thin bundled filaments. In accordance with this study, these Flabellophyton fossil assemblages are probably benthic macroalgal fossils. Here, the fossil assemblages of Flabellophyton from India are described for the first time.

Authors: Kumar Neeraj , Srivastava Shubha 
Published: June 2024

ABSTRACT
In the present paper, the water quality of the Konar reservoir area in the Hazaribag district of Jharkhand, India, has been investigated and with this view, the different physico-chemical variables, including pH, Dissolved Oxygen, Electrical Conductivity, TDS, Temperature, cations (Ca2+, Mg2+, Na+, K+), anions (CO32−, HCO3−, Cl−, F−, SO42−, NO3−) have been analyzed. According to Schoeller diagram, the order of major cations and anions for groundwater are Ca2+ &gt; Na+ &gt; Mg2+ &gt; K+ and HCO3− &gt; SO42− &gt; Cl− &gt; NO3− and for surface water are Na+ &gt; Ca2+ &gt; Mg2+ &gt; K+ and Cl− &gt; HCO3− &gt; NO3− &gt; SO42− respectively. The calculated water quality index shows that 100% of the samples of surface water are of excellent water quality, while 17% of the samples of groundwater are of excellent and 83% fall under the good category. The Gibbs Plot indicates that the rock-water interaction mechanism is dominant, Giggenbach triangle indicates that the waters have not yet reached equilibrium and are still in an immature state, although the Piper plot demonstrates that most of the surface water samples (78%) are mixed facies of Ca2+-Mg2+-Cl− and 22% are of Na+–Cl− type. All groundwater samples are mixed facies of Ca2+– HCO3− type. According to the Durov plot, 100% of surface water samples exhibit simple dissolution or mixing and majority of the ions in all groundwater samples are calcium and bicarbonate, showing the influence of limestone deposits. Almost all of the water samples from the Konar reservoir area were found to be appropriate for irrigation, according to the Residual Sodium Carbonate, Residual Sodium Bicarbonate, Sodium Percentage, Permeability Index, Kelley’s Ratio, Sodium Adsorption Ratio, United States Salinity Laboratory (USSL) and Wilcox diagrams.

This study aimed to investigate the hypothesis that minimally invasive coronary artery bypass grafting (CABG) induces fewer hemodynamic alterations compared to conventional approaches, attributing this to reduced heart rotation during grafting. Given the critical role of hemodynamic stability in patient outcomes and the growing popularity of minimally invasive CABG, we sought to assess and compare the hemodynamic responses during left anterior descending artery grafting. This randomized controlled trial was conducted at a tertiary center, enrolling a total of 60 patients, with 30 in each group. Parameters such as heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), and perfusion index (PI) were measured at baseline, after octopus stabilization prior to grafting, at 3 minutes during grafting, and at the end of grafting. Additionally, serum lactate levels were assessed at baseline and upon completion of grafting. The baseline HR was comparable between the groups. However, the trends in HR revealed a significant increase in the conventional group after octopus stabilization (P value = 0.0038), at 3 minutes post-initiation of grafting (p &#60; 0.001), and at the completion of grafting (P value = 0.001). MAP and CVP remained comparable at all time points. Notably, PI showed a significant increase in the conventional group during positioning (after octopus stabilization), at 3 minutes post-initiation of grafting, and at the completion of grafting. There were no significant differences in lactate levels between the groups. Despite no significant differences in MAP, CVP, and lactate levels, our findings highlight significant disparities in HR and PI between the two groups. We conclude that the observed variations in heart rate may be attributed to minimal positional changes in the minimally invasive approach compared to the conventional approach.

Though composite resins have received popularity as restorative materials because of their physical properties, there was a dearth in the research about fracture resistance among recently emerged composite systems including Tokuyama Estelite Sigma Quick, Admira Fusion, and Beautifil II LS nanohybrid composite systems. To compare and evaluate the fracture resistance of maxillary premolars with class II mesio occluso distal cavities restored with Tokuyama Estelite Sigma Quick, Admira Fusion, and Beautifil II LS nanohybrid composite systems. Current invitro research was conducted on 44 intact human premolar teeth- Eleven specimens were kept completely intact for control group (Group G1). Class II MOD cavities were done with high-speed handpiece and under constant irrigation in remaining 33 teeth, Group G2, Group G3, Group G4 were restored with Tokuyama Estelite Sigma Quick (Tokuyama Dental, Tokyo, Japan.), Beautifil II LS (Shofu, Germany.), Admira Fusion (Shofu, Germany.) respectively. SPSS version 20 software to analyse the data; and ANOVA followed by Tukey’s post-hoc analysis to compare the fracture resistance were used. With a fracture resistance of 1297.27±10.27 N, Group 1 (Control) had highest fracture resistance. Group 4 has the least fracture resistance (Admira Fusion). Every pairwise comparison was significant too. Among the three materials studied, Beautifil II LS had higher fracture resistance and Admira Fusion had the least fracture resistance.
