Published: June 2024

AbstractIt is a well-known fact that many sophisticated works consume a lot of human resources, leading to the need to find effective alternative. The manufacturing industry demands a lot of human resources, with around half of the global working population participating in this sector. Challenges such as sudden conflicts in the data, disasters, and loss of productivity are encountered by the manufacturing industries and can be overcome by monitoring machine performance data and automatically configuring the machines according to changing needs. This emphasizes the importance of the Internet of Things (IoT) in addressing niche areas of manufacturing. IoT is a buzzword heard everywhere around the globe. Implementing this technology makes most of the work more accessible than other conventional methods. This has created a lot of research interest on this topic. Among many manufacturing sectors, polymer composite material manufacturing is one of the most demanding. This review article purely focuses on polymer composite manufacturing and its allied processes. The consolidation of data is based on the influence of IoT on the extraction of fibers and manufacturing of polymer composite material using novel techniques, quality assessment of manufactured polymer composite material, challenges faced in exploring the use of IoT, and future scope. It can be stated from the survey that various researchers have minimally explored the incorporation of IoT, but its future looks very promising in terms of producing high-quality products at less time and lower cost by integrating this technique with conventional methods.

Authors: Akenteva Marina S. , Kargapolova Nina A. , Ogorodnikov Vasily A. 
Published: June 2024

Abstract
In this paper, we present three algorithms for simulation of intervals of stationary vector and scalar sequences with partial distributions of their subsequences of fixed length in the form of a mixture of Gaussian distributions. The first algorithm is based on superposition of two Gaussian vector processes and the second and third ones use the method of conditional distributions and the method of superpositions to simulate the mixtures and to select realizations for approximate construction of conditional realizations. Some properties of these algorithms are presented.

Published: June 2024

Abstract
The paper deals with Monte Carlo simulation of polarized radiative transfer and lidar returns in sensing of atmospheric clouds. The Stokes parameters were used to describe the transfer of polarized radiation, and computation of the lidar returns was based on flux-at-point estimators. We consider modifications of the numerical algorithm with scattering according to the phase function for unpolarized light and with scattering depending on polarization. Numerical experiments were performed for lidar sensing of waterdrop clouds.
Making sense of pain in inflammatory bowel disease (IBD): A qualitative study
Authors: Kacorova Adela , Williams Amanda C. de C. 
Published: June 2024

Abstract

Objectives
Inflammatory bowel disease (IBD) is a chronic, gastrointestinal tract condition, in which pain is one of the most widespread and debilitating symptoms, yet research about how individuals make sense of their IBD pain is lacking. The current study aimed to explore how individuals with IBD understand their pain.

Methods
Twenty participants, recruited via the Crohn’s & Colitis UK charity, were interviewed about their understanding of their IBD pain using the Grid Elaboration Method that elicits free associations on which it invites elaboration. Thematic analysis was used to organise transcribed verbatim data.

Results
Three related themes – making sense of my pain, navigating my care and support and it takes its toll – comprising seven sub-themes, illustrated the ways in which participants made sense of pain experientially, multi-dimensionally, and in the broader context of IBD and its symptoms. The psychological impact of pain was evident across all interviews.

Conclusions
The findings are consistent with other research in IBD pain, demonstrating the importance of pain in IBD. Sense-making underpins both emotional and practical responses to pain and ideally is constructed as an integral part of clinical care of IBD.

Published: June 2024

Abstract

Objectives
We aimed to investigate the relationship among proprotein convertase subtilisin/kexin type 9 (PCSK9), adropin levels, inflammation, and sleep variables in non-diabetic males with severe obstructive sleep apnea (OSA).

Methods
This cross-sectional study included adults aged 18 to 65 who underwent polysomnography due to sleep problems between July 2019 and August 2020. Participants were grouped based on their apnea-hypopnea index (AHI). We included 32 males with simple snoring (AHI<5 events/h) as the controls and 48 males with severe OSA (AHI≥30 events/h). Furthermore, patients with severe OSA were divided into two groups based on body mass index (BMI), resulting in three groups in total. Adropin and PCSK9 were analyzed using the enzyme-linked immunosorbent assay method.

Results
In severe OSA with BMI≥30 kg/m2, compared to the controls, blood pressure values, interleukin-6 (IL-6), white blood cell (WBC) count, systemic inflammation response index, neutrophil, monocyte counts were found to be higher, but adropin/BMI, adropin/waist circumference, adropin/neck circumference were significantly lower. Adropin/BMI had the highest correlation coefficient with IL-6. Although there was no significant difference in PCSK9 levels among the groups, PCSK9 was independently correlated with the WBC and its subsets.

Conclusions
Our study is of clinical importance as it is the first to show a relationship between PCSK9 and inflammation markers in severe OSA. Also, this study demonstrated the potential value of adropin, in combination with BMI, as a valuable indicator for assessing inflammation and OSA severity.

Статья посвящена исследованию процессов глагольной неологизации в 2000–2020 гг. на материа-ле бесприставочных глаголов, имеющих в своей структуре суффиксы -ова-, -ева-, -изова-, -ирова-, -изирова-. Основной материал взят из готовящегося к печати словаря «Неологизмы XXI века: глаго-лы» под ред. Т. Н. Буцевой. Исследуемый базовый материал – 66 неоглаголов (6,6% от общего объе-ма словника этого словаря, около 1000 глагольных неолексем). Однако при оценке степени узуали-зации новых суффиксальных глаголов учитываются производные: 207 глаголов, образованных от них префиксальным способом и 64 глагола, произведенных постфиксальным способом (с помощью постфикса -ся).Актуальность темы определяется недостаточной полнотой выявления новых глаголов, во многом обусловленной их относительной немногочисленностью в неологическом потоке, а также отстава-нием их словарной фиксации. Центральная исследовательская проблема статьи – проблематизиро-вать критерии разграничения суффиксальных глагольных новообразований, возникших на русской почве, и глагольных заимствований, суффиксально оформленных при вхождении в русский язык.Новые глаголы данной словообразовательной структуры описываются на фоне истории форми-рования данных суффиксов в русском языке. В ходе исследования анализируется продуктивность этих формантов в новейшее время, объясняется наблюдаемая орфографическая вариативность, описываются имеющая место словообразовательная синонимия, семантические и стилистические особенности, определяется степень освоенности неоглаголов русским языком, раскрывается сло-вообразовательная потенция новых суффиксально образованных и суффиксально оформленных глаголов.Цель статьи – представить глагольные неологизмы новейшего периода, образованные и оформ-ленные с помощью суффиксов -ова-, -ева-, -изова-, -ирова-, -изирова-, дать их комплексную характе-ристику, показать динамику неологического процесса через вовлечение этих глаголов в словообра-зовательные процессы. Методами исследования являются словообразовательный, компаративный, классификационный, этимологический, дефиниционный.
Multivariate Assessment of Groundwater Depletion and Recharge
Prospect in a Sub-tropical Basin of Eastern India
Authors: Ghosh Sandipan , Kundu Soumya 
Published: June 2024

Abstract
The present study aims to highlight the groundwater-stress condition of the Quaternary 一 recent alluvial region escalated by anthropogenic extraction of water resources in the western Bengal Basin (Purba Bardhaman, West Bengal, India). With the rapid development of irrigation technology, high crop yield, water- consumed rice varieties, and high cropping intensity, the farmers of the river basin go to deeper underground aquifers (&gt;180 m bgl) to extract water for summer rice (Boro) cultivation. In this study, the five semi-critical blocks (Mangolkote, Bhatai; Manteswai; Purbasthali II, and Memari II) of Purba Bardhaman district have experienced statistically significant pre-monsoon fall (0.404 m yr- 1 to 1.099 m yr-1) and post-monsoon fall of groundwater level from 0.486 m yr-1 to 2.214 m yr-1. Principal component analysis reflects that annual irrigation draft, annual replenishable groundwater unit, net groundwater availability, Boro rice cultivation area, area to be covered on each day irrigation for Boro, and daily pump discharge required for Boro irrigation are the key factors to escalate groundwater decline. This study reveals that Galsi II, Bardhaman I and II, Katwa I, and Purbasthali I blocks will experience a water-stress or groundwater drought in future. The model of groundwater recharge potential zone shows four principal categories of groundwater prospect area in the basin, viz., poor (0.08 %), moderate (5.78 %), good (68.96 %), and very good (25.18 %). These findings provide the relevant information for planners of groundwater resources to upscale groundwater management procedures and enhance the sustainability of agricultural systems in the study area.

Published: June 2024

Abstract
The clumped isotope paleothermometry is used to estimate minimum burial depth of the mid Eocene Harudi and Fulra Limestone Formations of Kachchh, western India. The Nummulites and other fossil foraminiferal genera were separated for conventional (δ18O, δ13C) and clumped isotopic (Δ47) measurements. The measurements were also made on whole rock (WR) to visualize the different phases of diagenetic alteration, expected depth of burial and capacity to generate hydrocarbon. The measured δ18O and δ13C values of WR samples vary between -3.09 and -2.21‰ and -0.78 and 0.96‰ respectively, with average values of -2.88‰ and 0.16‰. The δ18O and δ13C values of benthic foraminifera vary between -3.52 and -3.20‰ (Average: -3.35±0.013) and -1.04 and 0.81‰ (Average: 0.26±0.76) respectively. The measured Δ47 for the foraminifera translates to temperature of 35 and 49°C and between 26 and 48°C for WR indicating minor diagenetic alteration. The minimum estimates for the burial depth of the studied formations are up to 2 km which is based on the temperature difference between the ecological preference temperature of benthic foraminifera and the diagenetically altered foraminifera and δ13C of WR and foraminifera, indicating that rocks have potential to generate methane.
Present-day Fault Kinematics and their Reactivation Likelihood within and South of the North Tanzania Divergence (NTD), East African Rift System: Implication for Geo-hazards Assessment
Authors: Macheyeki Athanas Simon 
Published: June 2024

Abstract
This study investigates the relationship between the North Tanzania Divergence (NTD), the southern part of the NTD and the rift structures in the eastern part of the East African Rift System (EARS). It also assesses the susceptibility of these structures to reactivation under the current stress field. Fault slip data and focal mechanisms from various sources have been used to determine the minimum horizontal stress axes (Shmin) of different faults, including the Eyasi rift border fault south of the NTD.
The analysis reveals that faults trending NW-SE to NNW-SSE have a sinistral sense of movement, while those trending NE-SW generally have a dextral sense of movement. The N60°E trending faults that dip easterly are not optimally oriented with the current stress field and have a low to moderate likelihood of reactivation. This includes the NE-SW trending Eyasi rift border fault (part of the NTD) and other structures oriented N60°E south of the NTD, with a computed slip tendency (Ts) of less than 0.5. Faults trending N-S, NNW-SSE, and NNE-SSW, on the other hand, have a high to the highest likelihood of reactivation (Ts &gt; 0.85). The other faults in the study area, which trend NE-SW or NW-SE, have Ts values expressed as 0.5 ≤ Ts &lt; 0.85.
These findings have important implications for earthquake risk assessment in the NTD and south of the NTD, as geological constraints need to be taken into account for better management and mitigation. The results could be applied elsewhere in the EARS provided that they are under E-W extensional stress regime.

Abstract
We made an attempt to review salient recent research since last five years on the physicochemical aspects of volcanic and mantle-derived material, from the Indian context. The Review essentially confines itself to the rock types of basalts and mafic dykes, kimberlites, lamproites, lamprophyres, and carbonatites with a focus on their regional representation from the various domains of the Indian shield in a chronological sequence. This is a part of academic task of the International Association of Volcanology and Chemistry of the Earth’s Interior of International Union of Geodesy and Geophysics (IUGG).
Pillow Morphology of Bathani Volcano-sedimentary Sequence of Eastern Indian Shield: Inferences on the Geotectonic and Geo-Environments
Authors: Ahmad Mansoor , Paul Abdul Qayoom , Saikia A. 
Published: June 2024

AbstractThe Palaeo-proterozoic Bathani volcano-sedimentary sequence (BVSs) at the northeastern fringe of the Central Indian Tectonic Zone (CITZ), comprises three distinct litho-domains: (i) intrusive granitoid, having xenoliths of basalt, pyroxenite-gabbro-anorthosite suits (Northern Domain), (ii) low-grade volcano-sedimentary sequence along with concordant mafic-ultramafic intrusion (Central Domain) and (iii) folded clastic metasedimentary rocks (Southern Domain). The granitoid is intruded into the Central Domain, where pillow basalt with primary structure is well exposed. The volcanological and morphometric study of the pillows of Central Domain is attempted to understand the physicochemical characteristics and tectonic setup of the magma emplacement. The pillows are small to medium normal-sized with spheroidal, lozenge, and tubular shapes and preserve the primary features like radial and concentric cracks, selvage, pipe vesicles, voids, drain away cavities, way-up features, etc. A low-viscosity magma outpouring over a steep to moderate depositional slope is being deciphered from the morphological study of pillows. The stretching and fast-spreading growth mechanisms with low effusion under a rapid cooling rate have been inferred for these pillows. The morphological features of the rock types and pillows of the BVSs suggest a shallow water (&lt;1000m) divergent rift basin of the back-arc tectonic setting. The trace elemental discrimination plots support the basaltic composition of pillows with E-MORB and back-arc basin environment. The lithological setup, tectonic setting, and regional correlation of BVSs advocate it as an eastern continuation of the Palaeo-proterozoic Mahakoshal belt within the Son Narmada Lineament (SNL) zone of CITZ.
The Ancient Metal Miners of Vadnagar, Delwara and Mandli, Western India
Authors: Grover A. K. 
Published: June 2024

AbstractIndia is dotted with myriads of ancient metal mines or old workings in almost all the states, some of which have great antiquity (&gt;4,000 yrs) and reaching considerable depth (upto 260 m). These stand as testimony to the mining skill of our ancestors, especially in the absence of mining tools. Several of these old metal mines, when explored by modern methods have yielded sizable deposits e.g. Hutti, Bhukia (gold), Rajpura-Dariba (multi-metal), Agucha (lead-zinc-silver), Agnigundala (lead-copper), Khetri (copper), etc. A few ancient Indian treatises describe the processes of metal extraction from the ores but records are scanty on the methods of mining and mining communities. Most experts consider that, the history of mining in India is obscured in the mist of antiquity and opine that ‘we lack the knowledge of old miners of India, as to who they were, from where they came or what was their fate’. The trailblazers though did not leave direct records nevertheless the opportunity is not closed to reconstruct missing pages related to ancient metal miners in the history of mining in India.An attempt has been made in this paper to bring out details of these miners based on comprehensive study and analysis of archaeological, geological, ancient metallurgical, historical, etymological and modern age data in conjunction with locals in the field, especially on those who were active in mining in border areas of present Gujarat, Madhya Pradesh and Rajasthan in western India. It resulted in establishing the people of Vadnagar, Delwara and Mandli localities as expert miners, who were responsible for opening and operating a large number of mines in the region viz. Ambaji, Bhukia, Delwara, Khandia, Zawar, etc. Archaeological evidences and radiocarbon dates attest to a Chalcolithic to pre-historical period of some of these old mines. Nomenclature of some gold bearing rivers and gold mining localities in the country displaying Vedic gold names speaks for their antiquity. Mauryans (321-185 BC) accelerated metal mining in their empire, which was followed by other dynasties till Rajputs who were assisted by tribal Bhils. The knowhow of ancient metal miners of Vadnagar, Delwara and Mandli seems to have descended from Mahabharata and Harappan tradition of Gujarat (3950-900 BC) and Ahar-Banas (3600-1800 BC) culture of Rajasthan. During Mughal invasions many miners and metal workers had migrated to remote Himalayan areas (present Himachal Pradesh, Uttarakhand) or Hindu kingdoms (present Maharashtra, Odisha) where they adopted nomenclature of their place of origin (Vadnagar, Delwara and Mandli) to their new settlements. Some of these experts took-up mining profession while others developed expertise as blacksmiths/ whitesmiths or even agriculturists. Zinc coins of Kangra (14th Century AD) kings seem to have produced by these migrating metal experts who knew the technique of zinc distillation from ore of Zawar mines, the people of which are considered as first to smelt Industrial zinc in the world.
Carbonate-hosted U-deposit in the Tummalapalle Area, Andhra Pradesh, India: A Potential Source to Generate Critical Minerals of REs, V, Mo, Co, Ni, Cu, Ag and Phosphate as Value-added Byproducts
Authors: Raju R. Dhana 
Published: June 2024

AbstractThe unique, large-tonnage (amongst the Indian U-deposits; hitherto ~ 0.222 million tonnes, constituting 59% of the Indian U-resources) but very low-grade (~ 0.045% U3O8) sedimentary, impure carbonate (dolostone)-hosted U-deposit, established by the Atomic Minerals Directorate for Exploration and Research (AMD), occurs at Tummalapalle (TMP) and its contiguous areas over a ~ 160-km long belt in the Kadapa, Anantapur and Kurnool districts of Andhra Pradesh, India. Since 2012, the TMP U-deposit has been under commercial utilization by the Uranium Corporation of India Ltd. (UCIL) focussing for recovery of U with underground mining and nearby processing plant. Petro-/minera-graphic and geochemical characterisation of the U-ore shows major impurities of phosphate and silicate minerals, besides accessory ore minerals, mainly of U and sulphides. From this ore, it may be possible to generate some of the most sought-after critical minerals (CMs), namely the rare earths (REs), V, Mo, Co, Ni, Cu, Ag, and phosphate as value-added by-products from its U-phases, sulphides and collophane. For this, it is proposed to undertake an integrated, comprehensive R&D project on the ore for (i) extraction, processing, and marketing of the above CMs, which will lead to a low-cost and more profitable recovery of its low-grade U, (ii) providing a cheap, natural phosphate for agriculture, (iii) treating dreaded fluorosis by carbonate-powder, and (iv) reducing the mining-/processing-waste and tailings, all of which together address the environment, society, and governance (ESG) in the study area.
Geochemical and Isotopic Investigation of Carbonate Deposits in the Central Kaladgi Basin, North Karnataka

Published: June 2024

AbstractCharacteristic argillaceous-carbonate sediments covering parts of Belgaum, Bijapur and Bagalkot districts in north Karnataka have extensive deposits of high-grade limestone and have been commercially exploited since 1836. Despite their massive occurrence and commercial importance, the carbonate deposits in the Kaladgi basin have yet to receive enough attention. This study attempts to decipher the genetic aspects of the carbonate deposits occurring in the Neerubudihal region within the central part of the Kaladgi basin. The whole-rock carbon and oxygen isotopic compositions and the major and trace elemental compositions of the studied carbonates indicate that the rocks suffered a weak postdiagenetic alteration and retained the characteristics specific to the original diagenetic environment. The paleosalinity and palaeotemperature estimations reveal the carbonate precipitation in a stable marine environment in the study area with high salinity (av. 125) conditions at an average temperature of ~59 °C. The major and trace elemental studies classify the carbonates as dolomitic limestones and point to the dominance of the sedimentary process in their genesis. The carbon and oxygen isotopic studies suggest that the upper parts of the Bagalkot Group in the Kaladgi Basin had relatively lower organic content and diagenetic alteration than in the contemporary Bhima basin.
