Published: April 2023

The objective of the current study was to re-examine the chemical components of the essential oil (EO) from the aerial parts of Skimmia anquetilia N.P. Taylor & Airy Shaw in two different seasons designated as Skimmia anquetilia rainy season essential oil (SKREO) and Skimmia anquetilia winter season essential oil (SKWEO). The GC-MS analysis of SKREO and SKWEO resulted in the identification of 42 and 48 constituents, comprising of 95.3 % and 95.4 % of the total composition respectively. Both SKREO and SKWEO varied in their chemical composition in terms of quantity viz: linalyl acetate (15.8% - 17.6%), linalool (13.2% - 13.9%), geijerene (11.6% - 11.7%), α-thujene (11.3% - 11.1%), α-terpineol (6.1% - 6.1%), geranyl acetate (5.0% - 5.1%), α-terpinyl acetate (3.3% - 3.1%), myrcene (3.0% - 3.1%), geraniol (2.6% - 1.9%), α-pinene (2.1% - 2.2%), trans-β-ocimene (2.1% - 2.3%), cis-β-ocimene (2.0% - 2.2%) and neryl acetate (2.3% - 2.4%). Besides qualitative differences SKREO and SKWEO, both were studied for their pesticidal activities. The study exhibited potent antifeedant activity against Spodoptera litura and nematicidal activity against Meloidogyne incognita. Based on the present observations, it was found that besides its academic importance, shrub Skimmia anquetilia can be a good source of phytochemicals like linalyl acetate, linalool, geijerene, thujene and can be used for the development of herbal source for antifeedant and nematicidal activity after proper clinical trials.

Plumeria obtuse L. (Apocynaceae) is an ornate outdoor plant. The plant was traditionally used during accidentalinjuries. However, the pharmacognosy of this plant is very poorly explored. Therefore, we have conducted this study to assess the distinctive qualities of the P. obtusa. To investigate P. obtusa seed pods’ preliminary pharmacognostic, physical-chemical, phytochemical, microscopic, and phytoconstituent potential. Initially, the shape and microscopic characteristics of plant seed pods were assessed. Physicochemical analysis was used for the standardization. Utilizing several chemical techniques, phytoconstituents were evaluated qualitatively. This was followed by quantitative estimation and analytical profiling of various phytoconstituents. The basic characteristics of the seed pod have been documented by macroscopy to be its brown color, sweet aroma, bitter flavor, coarse texture, and rough fracture. Microscopy showed the existence of vascular bundles, lignified fibers, calcium oxalate crystals and arteries. The results of the physicochemical analysis revealed no foreign organic matter, 2.8 % weight-average moisture content and a high total ash value of 14.80 compared to an acid insoluble ash value of 0.70, which indicated that there was less inorganic matter in the plant. The extractive values were 3.93, 6.03 and 10.16 % w/w for water soluble, alcohol soluble and hydro-alcoholic soluble extracts respectively. Flavonoids, glycosides, saponins, phenolic constituents, tannins and carbohydrates were found during early phytochemical analysis. Instrumental analysis has given an idea about functional groups present whereas GCMS technique helped in identification of phytoconstituents. The results of this study can be significantly used as a reference support for quality control and standardization of P. obtusa and preparation of a monograph of plant.
Geometric arcs and fundamental groups of rigid spaces
Authors: Achinger Piotr , Lara Marcin , Youcis Alex
Published: April 2023

We develop the notion of ageometric coveringof a rigid space 𝑋, which yields a larger class of covering spaces than that studied previously by de Jong. Geometric coverings are closed under disjoint unions and are étale local on 𝑋. If 𝑋 is connected, its geometric coverings form a tame infinite Galois category and hence are classified by a topological group. The definition is based on the property of lifting of “geometric arcs” and is meant to be an analogue of the notion developed for schemes by Bhatt and Scholze.
Norms versus Interpretations: Human Rights Universality Revisited
Authors: García Escobar Gabriela
Published: April 2023

Debates on human rights universality frame universality according to an anthropological view called Western universalism and consider that “cultural relativism” is equivalent to any other framework. Thus, the discussion on this topic has been reduced to who is the rights-holder and the concept of human rights itself. There is a third approach to universality that must be addressed: the universality of interpretations. Most critics of human rights universality do not contest internationally agreed human rights norms (as established in treaties). Rather, they react against interpretations or standards as have been developed by human rights mechanisms. Accordingly, this paper explores three positions that have been developed around this notion: flexible Westerns, dialogical perspectives, and bottom-up approaches.

Published: April 2023

Aluminium (Al) and its constituent alloys has been consistently favoured as a promising material for industrial applications. In conventional casting technique of Al alloys, alloying elements are amalgamated in molten pool of Al melt followed by manual skimming. In contrast, batch type manufacturing includes intrinsic mixing and casting discontinuity, which negatively impacts the flexibility and cost-effectiveness of the process, resulting in a decline in the overall efficacy of the process. In the present study, a novel continuous casting processing route has been used to make Al–Cu binary alloys of different compositions. The newly designed technique makes use of a novel mechanical force convection technology, as well as bottom feeding of the molten metal and alloying element throughout the manufacturing process. The bottom feeding along with rotational swirl ensures better amalgamation of alloying element. Feed rates of Al melt and Al–Cu master alloy were mathematically modelled to obtain the desired alloy composition. The microstructural characterization of the developed alloys exhibit Al–Cu intermetallic phase invariably distributed throughout the sample, which concludes a better performing processing route to prepare Al–Cu binary alloys.

The influence of fibrous suspension flow regimes on the formation of tissue paper manufactured from different furnish compositions
Authors: Mendes Afonso H. T. , Park Song W.
Published: April 2023

The present work was based on analysis of the flow regime of fibre suspensions, that corresponds to furnishes and process conditions typically established for tissue paper manufacturing,i.e., under the common range of stock consistencies at the machine headbox and most usual furnish compositions. The flocculation potential of fibre suspensions used for toilet papers, facial tissues, paper towels and table napkins were evaluated on the principles of analytical concepts for fibre agglomeration propensity. The results show crowding numbers from 5.0 to 69.0, depending on the type of fibre or fibre blending ratios. The findings regarding agglomeration factors indicate that flow regimes are mainly in semi-concentrated and around gel state zones but reached the concentrated flow regime, in extreme conditions of fibre morphology and stock consistency. The influence of hardwood and softwood mixture ratios on the fibre suspension features is shown and discussed for common formulations of tissue base paper. The effect of fibre length and coarseness on the flocculation potential and the impacts of fibre suspension flow regimes on the structural properties of tissue paper, such as the formation uniformity are discussed, demonstrating the reasons for the preferred use of high hardwood content in furnish balance for tissue paper manufacturing.
The Impact of Transportation on Pottery Industries in Roman Britain
Authors: Wiseman Rob , Bulik Olivia , Lobo José , Lodwick Lisa , Ortman Scott G.
Published: April 2023

The distribution of Roman pottery depended on the transportation system which moved it. Here we trace developments in these distributions during the Roman period in Britain to document how the transportation system developed and assess its impact on the island’s economy. We created a database with records from 775 excavations at 652 sites, and data on over two million pottery sherds. By analyzing the changing distributions of pottery from production centers, we are able to measure improvements in the Roman transportation system over time. These improvements seem to have been most rapid soon after conquest, with transport costs almost halving in the first century of Roman occupation. As the road network expanded and transportation technology improved and pottery gained access to wider markets, producers’ dominance over their local markets declined as rival products became more accessible, and certain industries dramatically increased their outputs. Production by small industries fell in our Middle and Later Roman periods.
El costo y la disponibilidad de agua en la producción de la industria cervecera mexicana
Authors: Vásquez Galan Belem Iliana , Corrales Corrales Salvador , González Avila María Eugenia , Martínez Sidón Gilberto
Published: April 2023

El objetivo es analizar la producción de cerveza en función del volumen de agua concesionada a la industria y su precio en el periodo 2013-2020. Para ello, se estimó un modelo de producción en función del agua concesionada por la Comisión Nacional del Agua (Conagua) y la productividad laboral, además de otro modelo del agua concesionada en función del precio por metro cúbico según la zona de disponibilidad hídrica. Los resultados indican que el agua concesionada tiene un efecto positivo y estadísticamente significativo en la producción cervecera, con una elasticidad igual a 1.327. Por otro lado, el agua concesionada resultó positiva pero inelástica a los precios en las cuatro zonas hídricas. En términos de política pública, esto implica que el instrumento para regular el consumo industrial de agua tendría que ser mediante el otorgamiento de concesiones y no mediante tarifas de precios, como actualmente ocurre.

Authors: Godínez-Tovar Alejandra , Pozos-Radillo Blanca Elizabeth , Preciado-Serrano María de Lourdes
Published: April 2023

La pandemia por la covid-19 modificó las condiciones de trabajo de los docentes que tuvieron que trasladar su enseñanza al teletrabajo. Con ello se incrementó la carga mental de trabajo (CMT) debido a las demandas de su actividad y a los recursos para hacerle frente a esta nueva condición. El objetivo de la investigación fue comparar, según el nivel educativo en que imparten clases, la CMT de docentes mexicanos que laboraron en la modalidad de teletrabajo durante la pandemia covid-19. Participaron 112 docentes que respondieron un cuestionario de datos sociolaborales y la escala de CMT-53 Godínez-Preciado. Los resultados reportaron niveles altos de sobrecarga mental, demanda de la actividad, competencia laboral e inadecuada resolución de problemas planificados. Además, en esta última dimensión, se determinó diferencia significativa (F 2, 111 = 5.492, p = 0.005) entre los docentes que imparten clases en licenciatura respecto a los que imparten clases en secundaria.
Naturalistic spoken language comprehension is supported by alpha and beta oscillations
Authors: Zioga Ioanna , Weissbart Hugo , Lewis Ashley G. , Haegens Saskia , Martin Andrea E.
Published: April 2023

Brain oscillations are prevalent in all species and are involved in numerous perceptual operations. Alpha oscillations are thought to facilitate processing through the inhibition of task-irrelevant networks, while beta oscillations are linked to the putative reactivation of content representations. Can the proposed functional role of alpha and beta oscillations be generalized from low-level operations to higher-level cognitive processes? Here we address this question focusing on naturalistic spoken language comprehension. Twenty-two (18 female) Dutch native speakers listened to stories in Dutch and French while magnetoencephalography (MEG) was recorded. We used dependency parsing to identify three dependency states at each word: the number of (1) newly opened dependencies, (2) dependencies that remained open, and (3) resolved dependencies. We then constructed forward models to predict alpha and beta power from the dependency features. Results showed that dependency features predict alpha and beta power in language-related regions beyond low-level linguistic features. Left temporal, fundamental language regions are involved in language comprehension in alpha, while frontal and parietal, higher-order language regions, and motor regions are involved in beta. Critically, alpha- and beta-band dynamics seem to subserve language comprehension tapping into syntactic structure building and semantic composition by providing low-level mechanistic operations for inhibition and reactivation processes. Due to the temporal similarity of the alpha-beta responses, their potential functional dissociation remains to be elucidated. Overall, this study sheds light on the role of alpha and beta oscillations during naturalistic spoken language comprehension, providing evidence for the generalizability of these dynamics from perceptual to complex linguistic processes.

SIGNIFICANCE STATEMENT:

It remains unclear whether the proposed functional role of alpha and beta oscillations in perceptual and motor function is generalizable to higher-level cognitive processes, such as spoken language comprehension. We found that syntactic features predict alpha and beta power in language-related regions beyond low-level linguistic features when listening to naturalistic speech in a known language. We offer experimental findings that integrate a neuroscientific framework on the role of brain oscillations as “building blocks” with spoken language comprehension. This supports the view of a domain-general role of oscillations across the hierarchy of cognitive functions, from low-level sensory operations to abstract linguistic processes.
NUMERICAL MODELLING OF TEXTILE STRUCTURES: POTENTIAL AND LIMITS
Authors: BOŇKOVÁ KAROLÍNA
Published: April 2023

Numerical modelling, namely finite element modelling, is a standardised tool in many branches of engineering. In textile engineering, due to the complexity of the structure, many limitations occur in using this approach. Despite the limitations the finite element modelling of textiles has huge potential for the future. This contribution deals with FE modelling of tensile test in wale and course direction of single jersey knitted fabric. The meso level of the structure was chosen for the model, so it could be possible to track the behaviour of yarn interlacement during the simulated deformation. The virtual model was created according to parameters of single jersey knitted fabric sample, which was produced from polyester monofilament. By using monofilament instead of staple yarn, contacts between fibres in yarn could be excluded in FE model preparation. Two different computational programs were used for simulations – MSC Marc Metant for implicit computing approach and ANSYS LS-DYNA for explicit computing approach. The results from implicit and explicit solver were compared and discussed. Validation of models was done and results were included in the discussion. Due to big deformations of textiles, explicit solver appears to be more suitable for finite element modelling in textile engineering.
THE EFFECT OF POLYMER TYPE AND FIBER ORIENTATION ON THE COMPLIANCE PROPERTIES OF ELECTROSPUN VASCULAR GRAFTS

Published: April 2023

Vascular diseases are a major source of fatalities globally. However, the lack of accessibility of autologous vessels and the poor efficacy of commercial small-diameter vascular grafts limit surgical alternatives. Researchers therefore aimed to develop vascular prostheses that meet all requirements. Apart from the benefits of tissue-engineered grafts, significant obstacles that still hinder successful grafting include compliance mismatch, dilatation, thrombus development, and the absence of elastin. Among these issues, compliance mismatch between native vessel and artificial vascular scaffold has been mentioned in the literature as a possible cause of intimal hyperplasia, suture site rupture and endothelial and platelet cell damage. As a result, the usage of suitable materials and optimized fabrication techniques are required to achieve better control over the characteristics and functionality of the grafts. In particular, in the case of electrospun vascular grafts, the compliance can be adjusted throughout a broad range of values by adjusting the electrospinning parameters such as material selection, fiber orientation, porosity, and wall thickness. In this study, the electrospun vascular grafts consisting of pure PCL, PLA, and their blends were produced by using two different rotation speeds to achieve the oriented and non-oriented scaffolds. The impact of polymer type and fiber orientation on the compliance properties was evaluated. The results revealed that both material selection and fiber alignment have a significant effect on the compliance levels. PCL100_R grafts had the highest compliance value whereas the PCLPLA50_O scaffold had the lowest.
DESIGN OF ELECTRONICALLY CONTROLLED JACQUARD MACHINE FOR MULTI-SHED WEAVING MACHINES
Authors: ARSOY RAŞIT , ASLAN SELÇUK
Published: April 2023

The Jacquard shed opening system, which makes it possible to open the shed by controlling the warp threads in groups and obtain different designs and shapes, differs from other shed opening systems in that each group of warp threads and each of them can be controlled as needed. The various warp movements, which are limited by the number of frames in other shedding systems, are limited by the number of sinkers in the Jacquard system. Since all known Jacquard shedding systems are designed for operation with single shed weaving machines, they cannot be used for shedding on multiple weaving machines. In this study, a new electronically controlled jacquard machine for multiple shed weaving machines was developed, which eliminates this problem and enables the opening of the weaving compartments by controlling the warp threads individually in multiple shed weaving machines, thus allowing the weaving of all known jacquard fabric patterns. The technological and kinematic schemes of the jacquard machine were prepared taking into account the type of fabric to be produced, the operating principles of the weft insertion and shedding mechanisms to be used in the machine to be developed, and the expectations for improving the technical and economic indicators of the machine. The electronically controlled pattern reading system, which consists of modules in the machine, converts the electronic data into mechanical data to ensure shedding. In the cam shedding mechanism, which transmits motion to the knives in the form of a stepped shaft in the multiple weaving machine, the warp threads are placed on the knives so that they can move vertically. They are controlled by specially structured sinkers which, in contact with the blades, move from the lower to the upper state with the help of the blades and from the upper to the lower state with the help of springs. When the warp threads are to remain in the upper position according to the pattern, the sinkers are interlocked by electromagnets to form an undulating nozzle corresponding to the fabric pattern. By arranging the interlocking projections along the sinker, it is possible to match the density of the sinker to the density of the warp threads. Since the machine allows weaving of all known jacquard fabrics, the problem of not being able to produce weaves other than the rag foot weave, which is considered one of the major drawbacks of multiple shed weaving machines, has been solved.
IDENTIFYING THE MATERIALS IN ARCHAEOLOGICAL TEXTILES

Published: April 2023

Given their organic origin, textiles rank among the rarest archaeological finds. While the vast majority of these artefacts are preserved as small fragments or mineralised remnants, their detailed textile technology study provides interesting and important information about the use of textile techniques and the quality of processing. The most important information concerns the utilised textile materials, but for degraded textiles, these materials are among the most difficult information to obtain. Image analysis using electron microscopy (SEM) is a significant aide in this pursuit.
Acute onset of diabetes and rapid cognitive decline in a patient with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes syndrome
Authors: Tran Nam Quang , Phan Chien Cong , Vuong Tran Bao , Tran Thang Viet , Ma Phat Tung
Published: April 2023

Mitochondrial diseases are a group of rare diseases presenting with heterogeneous clinical, biochemical, and genetic disorders caused by mutations in the mitochondrial or nuclear genome. Multiple organs can be affected, particularly those with high energy demand. Diabetes is a common endocrine manifestation of mitochondrial diseases. The onset of mitochondrial diabetes can be latent or acute, and the presenting phenotype can be type 1- or type 2-like. Studies show that diabetes ais associated with latent progression of cognitive decline in patients with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome. Herein, we report a case of rapid cognitive decline after the acute onset of diabetes in a patient with MELAS syndrome. The patient was a 36-year-old woman who was hospitalized due to hyperglycemic crisis and seizures. She was diagnosed with MELAS syndrome two years previously, and had gradually progressing dementia and hearing loss. However, following the acute onset of diabetes, she developed rapid cognitive decline and loss of ability to perform daily activities. In conclusion, the acute onset of diabetes could be an associated risk factor for rapid cognitive decline in patients with MELAS syndrome. Thus, these patients as well as healthy carriers with related genetic mutations should undergo diabetes education and screening tests. Moreover, clinicians should be aware of the possibility for acute onset of hyperglycemic crisis, particularly in the presence of triggering factors.

Learning points

Diabetes is a common endocrine manifestation of mitochondrial diseases, presenting with a type 1- or type 2-like phenotype depending on the level of insulinopenia.

Metformin should be avoided in patients with mitochondrial diseases to prevent metformin-induced lactic acidosis.

Mitochondrial diabetes can manifest before or after the onset of MELAS syndrome.

In patients with MELAS syndrome, diabetes can initially manifest with a life-threatening severe hyperglycemic crisis and can cause rapid cognitive decline.

Diabetes screening tests (e.g. hemoglobin A1c, oral glucose tolerance test, or random blood glucose level measurement) should be performed either systematically or in the presence of symptoms, particularly after triggering events.

Genetic testing and counseling should be provided to patients and their families for the purpose of better understanding the inheritance, progression, and possible outcomes of the disease.

With the development of technology allowing for a rapid expansion of data science and machine learning in our everyday lives, a significant gap is forming in the global job market where the demand for qualified workers in these fields cannot be properly satisfied. This worrying trend calls for an immediate action in education, where these skills must be taught to students at all levels in an efficient and up-to-date manner. This paper gives an overview of the current state of data science and machine learning education globally and both at the high school and university levels, while outlining some illustrative and positive examples. Special focus is given to vocational education and training (VET), where the teaching of these skills is at its very beginning. Also presented and analysed are survey results concerning VET students in Slovenia, Serbia, and North Macedonia, and their knowledge, interests, and prerequisites regarding data science and machine learning. These results confirm the need for development of efficient and accessible curricula and courses on these subjects in vocational schools.

Authors: Kharasch Sigmund J. , Dumas Helene , Huang Calvin , Liteplo Andrew , Shokoohi Hamid , Kharasch Virginia
Published: April 2023

BACKGROUND AND OBJECTIVES

Children with medical complexity (CMC) have significant chronic health conditions that involve congenital or acquired multisystem disease associated with medical fragility, functional limitations, dependence on technology, and high health care utilization. The objective of this study was to describe the indications, applications, and point-of-care ultrasound (POCUS) findings in this population.

METHODS

A descriptive study of POCUS scans performed for clinical purposes in CMC admitted to a single pediatric postacute care hospital. All children for whom a POCUS was requested by a medical team provider were eligible for inclusion.

RESULTS

One hundred and four POCUS evaluations were performed for 33 patients. Diagnostic groups for the 33 patients included multiple congenital anomalies (41%), neurologic or neuromuscular (31%), prematurity (25%) and cardiac (3%). Lung, cardiac, and diaphragmatic ultrasound accounted for 57% of POCUS requested. POCUS was abnormal in 82% of diaphragmatic, 73% of lung, and 11% of cardiac ultrasounds. Twenty-three percent of POCUS studies were requested to answer a specific clinical question, 56% for follow-up information, and 21% for baseline evaluation.

CONCLUSIONS

Lung, diaphragmatic, and cardiac ultrasound were the most prevalent POCUS studies requested in a postacute care hospital. POCUS may offer an expanded role in such patients and settings by answering clinical questions and by providing baseline and follow-up information.
Textural-structural characteristics and mineral types of ores of the Aghlig-Filfilli mineralization area of the Duruja zone
Authors: Gadirova Teller S.
Published: April 2023

The black shale complex, which is organic carbon-bearing and characterized by syngenetic, epigenetic sulphidation and intense metamorphism in the Duruja structural-forma- tion zone of the southern slope of the Greater Caucasus, is the focus of geologists’ attention due to the mineralization areas, which are rich in significant non-ferrous, noble, radioactive metals, rare and rare earth elements. In order to determine the prospects of noble, non-ferrous, radioactive metals, rare and rare earth elements of the black shale of the Aghlig-Filfilli mineralization area of the Duruja zone, it is necessary to determine the mineralogical composition of the ores of the area, to study the textural-structural characteristics and to clarify whether the rocks of the zone are a source of complex ore raw materials. The object of the work is the mineragraphic and petrographic study of the numerous samples col- lected from the Aghlig-Filfilli mineralization area during the field expedition before the PhD admission period, during my post-graduate studies and currently in order to solve various important mineralogical and petrographic problems. In order to investigate the textural-structural characteristics and mineral types of the ores of the Aghlig-Filfilli mineralization area, thin sections and polished sections made from the samples were studied with the help of «Carl Zeiss» and «Polam-312» microscopes in transmitted and reflected rays. The composition, surface area and morphological characteristics of the monomineral samples were studied by the electron microscope «SEM». Accurate diagnosis of some minerals was carried out based on the results of their X-ray diffractometric analysis. According to the results of the research, the ores of the Aghlig-Filfilli mineralization area were formed in 3 stages: syngenetic, epigenetic and rem- ineralization as a result of strong metamorphism of syngenetic formations. At the same time, the origin of the ores of the Aghlıg-Filfilli mineralization area was studied. According to the results of the research, it was determined that epigenetic mineralization in contact with Aralig and Zangi deep faults in the north and south of the Aghlig-Filfilli area is of magmatogene origin (δ34S=1.6-4.6), and synge- netic mineralization in the black shales towards the center is of biogenic origin (δ34S= -18 – -22.6).
Systematics and typology of the relief forms of the Oleshkivski Sands
Authors: Kryvulchenko Anatolii I.
Published: April 2023

Oleshkivski Sands is one of the most peculiar regions of psammomorphic land- scapes in Europe and in particular the ancient delta region of the Left Bank of the Lower Dnipro. The territory of the sands consists of seven hilly sand massifs and six inter-arenial flat-level geocomplexes. The relief and peculiarities of the formation of this territory are still insufficiently studied, the relief of the intra-arenial landscapes is almost completely unexplored. The objectives of this study were sys- tematics and typology of the relief forms with approaches to elucidating the factors and mechanism of formation of geomorphological formations of Oleshkivski Sands. The methods of research of the relief of the Oleshkivski Sands were based on existing experience in identification, mapping, classification, analysis of sandy landforms, deciphering their portrayal on satellite images, as well as on many years of field research by the author. The generalized and systematized analysis of the relief, illustrated with maps, tables and photo- graphic materials, allowed us to form the systematics of the microforms of the relief and the typology of the mesorelief of the Olesh- kivski Sands. The results of such studies have revealled the morphological and genetic diversity of individual landforms within the arenas and inter-arenial geocomplexes, and a total of seven arenas of the Oleshkivski Sands, and respectively the complicated history of the formation of the region. Of the arenial geocomplexes, the hilly massifs and intra-arenial depressions were considered separately. Among the hilly massifs, the dominant were found to be hilly and undulated chaotically-configured structures, at some places with the distribution of parabolic dunes and dune ridges, and also the subordinate spread of the mound massifs. The morphological and genetic diversity of inter-arenial depressions was determined, which can be considered as diagnostic objects in the formation of the Oleshkivski Sands. The analysis of the relief of the territory of the Oleshkivski Sands revealed that different factors were in operation at different time stages of its formation – fluvial (fluvioglacial), aeolian, suffusion-subsidence, thalassogenic, anthropogenic. Аt the present stage the dominant are aeolian and anthropogenic factors. Special attention was paid to parallel hilly ridges of the Kinburnska and Kelegeiska arenas, considered in the context of the diluvial (catafluvial) paradigm as a manifestation of giant ripples. The discreetly formed parallel ridges and extended hollows of the Kinburn Peninsula are presented in the context of flood-freshet events in the history of the function- ing of the Dnipro and the Southern Bug, in places where water masses flow through watershed geocomplexes.

The article deals with the geospatial features of the banking infrastructure, which is a component of the financial infrastructure. Indirect financing infrastructure forms one of two groups of financial infrastructure. These patterns are characterized. The banking infrastructure is the most developed component of the financial infrastructure not only in the studied region, but also at the national and global levels. Regional factors, along with national and global trends, influence the particular development of the components of the financial network. Today, the development of the regional banking infrastructure has a great impact on the economic development of the region, as other components of the financial infrastructure are developing more slowly. Historical and geographic factors especially distinguish the Western region of Ukraine from others. The influence of historical preconditions that led to the formation of banks, which are a special type of financial and credit institutions, is assessed. This forms the basis for growth in the financial services market. Banking institutions are characterized by universality among other components of the monetary infrastructure. Banking infrastructure plays an important role in the financial sector and is pervasive in all spheres of geospace in today’s globalized world. Demographic and socio-geographic factors in the regions of the Western region of Ukraine are taken into account. The impact of international experience and local government reform was assessed. The patterns of uneven development at the regional level are characterized. The unevenness of financial flows of capital and the share of investments were revealed. The impact of Covid-19 pandemic effects and quarantine restrictions on elements of the banking infrastructure has been assessed. The observation period covers 2016, 2018, and 2021. The statistics collected in 2020 are not taken into account. The main reason is that 2020 was the beginning of the Covid-19 pandemic and most of the departments were operating in special modes or were temporarily closed.

The practical experience of long-term operation of hydrocarbon deposits con- firms the presence of geomechanical processes and their significant impact on the state of the gas-saturated massif of rocks. In fields that are being operated for a long time, the prospects for industrial hydrocarbon accumulation can be associated with secondary gas traps of non-traditional type, in particular, technogenic ones, which are formed in low-pore collectors. The authors carried out a detailed analysis of the well-known gas and gas condensate fields of Ukraine. The Rudkivske gas field of the Western oil-and-gas bearing region was chosen. The purpose of the study is to clarify the geological conditions for the formation of technogenic collectors and attracting additional volumes of gas under the action of a geomechanical factor while operating the Rudkivske gas field. The quoted results of the research prove the effect of gas extraction from the deposits of the J-h horizon on the formation of secondary technogenic collectors by attracting additional volumes of gas from the of ND-4, ND-5, ND-7 productive horizons and the formation of a new (ND-10) one, which subsequently connected to the gas production. Attracting additional gas volumes is due to the gas influx from newly made technogenic collectors, which were formed under the action of a geomechanical factor in the process of long-term development of the field. The formation of technogenic collectors occurred due to the compression of the main reservoir of the Jurassic age (J-h), the deformation of the rock strata, and the decomposition of the overlying rocks, the development of the crack propagation, permeability increase and gas recovery rising. The geomechanical factor management opens the prospect of obtaining additional industrial gas influx in the late stages of the development of gas and gas-condensate fields, by predicting the geological conditions for the formation of improved secondary filtration and capacitive properties favorable to form technogenic gas deposits.

The diatoms are one of the most significant organisms beneficial for biomonitoring investigations. The present study deals with the diatom and water samples collected from 10 different localities in the Thamirabarani River, Southern India. Diatom samples were collected by scraping stones with a toothbrush and squeezing macrophytes. Study of diatom valve morphology and measurements of diatoms were carried out using an optical miccroscope. The present study recorded 58 diatom taxa belonging to 25 genera. Among the diatoms, the taxonomical characters of 20 abundant diatom taxa viz. Aulacoseira granulata, Discostella stelligera, Navicula cryptocephala, Encyonema minutum, Gomphonema gandhii, Eunotia asterionelloides, Gomphonema parvulum, Brachysira neglectissima, Aulacoseira ambigua, Diadesmis confervacea, Nitzschia palea, Nitzschia amphibia, Sellaphora Americana, Staurosirella pinnata, Gomphonema affine, Fragilaria pararumpens, Eunotia incisa, Navicula erifuga, Navicula cryptotenella and Navicula rostellata are described and illustrated. In the present study abundant diatom genera were observed such as Aulacoseira, Discostella, Navicula, Encyonema, Gomphonema, Brachysira, Nitzschia, Sellaphora, Staurosirella, Fragilaria and Euno- tia. In abundant diatom taxa such as Aulacoseira granulate, Discostella stelligera, Gomphonema gandhii, Fragilaria pararumpens, Navicula cryptocephala, Navicula rostellata, Staurosirella pinnata water quality index values between 21-42 were recorded at Sites 1-9, which indicates unpolluted water. The abundant diatom taxa Diadesmis confervacea, Nitzschia palea, and Gomphonema parvulum were present at Site 10 and a water quality index value of 101 was recorded, indicating water polluted due to anthropogenic activity. The diatom assemblage of the present study was compared with various river systems to understand the environmental condition assessment. The water samples were analysed for assessment of the water quality.
Prospects for the oil and gas potential of the sedimentary strata of the South Caspian Basin according to paleotectonic and geodynamic criteria

Published: April 2023

In the article, based on the study of paleotectonic, paleotemperature properties of the evolution of the western and eastern semi-basins of the South Caspian depression (SCD) and of the local elevations that have developed there, we found that within the Absheron Ridge and Turkmen shelf, which make up the north-northeastern slope of the depression, compressive stresses played a key role in the formation of local elevations, development of faults and mud volcanism, and in their oil and gas potential. By using a number of paleoprofiles constructed based on the seismogeological profile running in a southwest-northeast direc- tion, as well as morphological specifics of the local elevations developed within both the Absheron Ridge and the Turkmen shelf, we plotted and analyzed isomorphic maps reflecting the properties of distribution of the compressive stresses. Based on the paleoanalysis, we determined that the isometric Janub elevation, neither morphologically nor genetically, can be included into the same anticline zone as the local elevations under consideration. Studies suggest that they have developed under different tectonic regimes and the Janub structure belongs to a group of folds formed under another tectonic regime, i.e. new predicted anticline zone. The Janub-2 elevation, located southeast of the Janub fold, can be attributed to the predicted new anticlinal zone. In order to trace the continuation of this anticline zone in the southeast direction and identify potentially promising new buried elevations, it is advisable to carry out new series of transverse deep seismic profiling works in the southwest-northeast direction. The analysis revealed that the oil and gas potential, folding and evolution of mud volcanism in the area under study are associated with geodynamic processes. The impact of compressive stresses, as a geodynamic factor, on folding and faulting of the sedimentary mantle, mud volcanism and oil and gas potential is a relevant topic to study. The main research objective was determining the directions of exploration works based on deeep structure, paleotectonic, geodynamic and paleotemperature evolution environment of the SCD.

Salem dolerites were collected across the dyke from various parts of the studied area for identifying the differentiation process of magma in the conduits from the compositional profile. The thick dolerites show NNW-SSE, NE-SW, and NW-SE trends. The studied dyke shows systematic composition increasing and decreasing in the chilled margin and centre of the dyke as the texture and concentration of plagioclase and pyroxene increase. Chilled margins show microcrystalline to intersertal, and the centre of the dyke show sub ophitic textures. The compatible oxide MgO, element Ni and the Mg number (100Mg/(Mg+FeT)) increased and the incompatible oxides TiO2, P2O5, and elements Zr decreased from the chilled margin to the centre of the dyke in the compositional profile show reverse fractionation trends (opposite to fractional crystallization) in the studied dykes except for Seeliyampatti dyke. The Seeliyampatti dolerites show opposite compositional variations indicating a normal fractionation trend from the other dykes of the study area. The reverse fractional trends in dykes resulting in the progressive increase of cumulate minerals growth against the dyke wall called the «cumulate process», however, the normal fractional trend in Seeliyampatti resulting in the progressive increase of more evolved magma successively removes the early chilled margin and fills the thick dyke with less compatible and more incompatible components toward the centre of the dyke. Although the normal trend in thick dyke considered the exceptional liquid process of magma differentiation that was formed more like fractional crystallization. Factor analysis also supports the differentiation process of magma. The first factor accounts total variance of 57.68% showing the positively loaded incompatible element and negatively loaded compatible elements.
