Authors: Khalifaturofi'ah Sholikha Oktavi , Indra Listyarti  , Ririn Poerwanti
Published: October 2023

This study delves into the determinants of profitability in conventional banks. This study uses a quantitative method to analyze the factors influencing bank profitability. This study uses balanced panel data using the fixed-effects model from 18 conventional banks from 2009 to 2021 in Indonesia. The results suggest that COVID-19 has a negative impact on profitability. Nevertheless, bank specifics such as capital and bank size positively influenced profitability, while efficiency significantly negatively influenced profitability. Moreover, this study delves into macroeconomic indicators, revealing their pronounced significance. Economic growth and interest rates emerged as substantial drivers, positively shaping bank profitability. Conversely, the exchange rate exerted a noteworthy negative influence on profitability. Bank stakeholders are expected to improve performance by increasing the bank's capital and assets. A bank should be able to increase its size through its total assets. Monetary policies, such as controlling interest and exchange rates, are found to be an important factor in determining banking profitability.

A automedicação é uma prática realizada por qualquer pessoa que decide tomar medicamentos por conta própria e muitas vezes desconhece os riscos que isso pode acarretar à sua saúde. Outro ponto relevante é que, além desses fatores, essa prática é observada em estudantes dos cursos na área da saúde. Em razão das intoxicações e problemas de saúde que a automedicação pode causar, principalmente em estudantes da área da saúde, já que os acadêmicos são ensinados e doutrinados quanto aos efeitos dessa prática durante o curso de graduação, tomou-se como objetivo investigar a prevalência da automedicação dos alunos de enfermagem em uma universidade privada. A pesquisa é um estudo transversal com abordagem quantitativa. Para quantificar a investigação, foi aplicado um questionário contendo 11 questões em 103 alunos de enfermagem. Como resultado, o autoconsumo de medicamentos foi considerado uma opção para 93 estudantes de enfermagem, a maioria do sexo feminino, com idade entre 18 a 20 anos, com convênio médico e cientes de possíveis riscos à saúde, mesmo após acesso a bulas. O quadro clínico que precedeu a automedicação incluiu, principalmente, cefaleia, gripes/resfriados e dores musculares. Houve preferência por medicamentos já utilizados, especialmente, analgésicos, anti-inflamatórios, antigripais e relaxantes musculares. Conclui-se que os alunos de enfermagem serviram de exemplo para a sociedade, ao se tornarem profissionais da saúde, e espera-se que tenham capacidade de orientar e informar os pacientes sobre os riscos da automedicação e a importância de procurar um profissional qualificado.

In the conditions of modern realities, the profession of a teacher is characterized by high emotional costs, high responsibility for the effectiveness of subject-subject relations, the quality and responsibility of educational results. Performing professional tasks, the teacher most often does not think about his culture of professional success, its role in life, career. This key problem must be addressed purposefully and continuously in higher education. A program has been developed to activate the process of developing a culture of professional success for a future teacher, implemented for pedagogical areas. The theoretical part of the program introduces students to the concept of “culture of professional success” as a systemic concept, taking into account two significant phenomena. The phenomenon of “culture” is the basic personal basis in which the result of upbringing and education of students is concentrated, manifested in the harmony of the physical, mental, spiritual, moral development of each student. The concept of “professional success” is an important supra-professional (meta) quality that orients the subject to a high level of professional self-determination, striving for professional growth. The practical part of the program is based on the development of competencies aimed at self-determination and a culture of professional success. The experimental work showed a high level of readiness of the future teacher to develop a culture of professional success at the university, in the network interaction “mentor — student employer” under a number of conditions: creation of a holistic cultural and educational environment of the environment of success; taking into account the dialectic of the relationship between self-determination and the culture of professional success; development of a system of theoretical and practical knowledge; study of indicators of the culture of professional success; acquaintance with the issues of intensification of pedagogical work, a comprehensive assessment of the professional and functional state — as one of the components of the culture of professional success and self-determination.

Published: October 2023

Physical rock property measurement is an important stage in energy exploration, both for hydrocarbons and geothermal sources. The value of physical rock properties can provide information about reservoir quality, and one of these properties is tortuosity. Tortuosity is an intrinsic property of porous materials that describes the level of complexity of the porous arrangement when a fluid passes through it. Conventionally, tortuosity values are measured through laboratory analysis and numerical simulation, but these measurements can take a long time. An alternative method for measuring tortuosity is using machine learning with a convolutional neural network (CNN). A CNN is a type of deep neural network designed to analyze multi-channel images and has been applied successfully to classification and non-linear regression problems. By training a CNN on a dataset of digital rock samples that have been simulated using numerical computation to obtain their tortuosity values, it is possible to demonstrate that CNNs can accurately predict the tortuosity of digital rock. The result is that the CNN model can predict tortuosity values with the Xception model being the most accurate with the lowest RMSE value of 0.90962.

Published: October 2023

The existence of geological structures is one of the important parameters in determining the permeability zone in a geothermal system. This research was conducted in a non-volcanic geothermal field, Bora, located in the province of Central Sulawesi, aiming to identify the subsurface features, especially geological structures related to permeability zones by optimizing geophysical data. Magnetotelluric (MT) 3D inversion modelling is some of the latest methods to identify geological structural patterns in geothermal systems. The results of the MT model and analysis its parameters can find variations in the distribution of subsurface resistivity, orientation of the direction of the prospect area, and indications of geological structure zones. The type and geometry of the geological structure associated with the high permeability zone can be complemented by determining the contrast of gravity values ​​and analysis of the maximum First Horizontal Derivative (FHD) and zero of the Second Vertical Derivative (SVD). Based on the analysis of geophysical data, it is possible to identify the permeability zone associated with the main structure, namely the Palu-Koro fault, delineate the geothermal reservoir at a depth of 1500-2000 meters and determine the location of well drilling. To visualize the geothermal system comprehensively, a conceptual model is developed by integrating the geophysical model with geological and geochemical data that are correlated with each other, therefore it can assist in determining the location of production well development.

Authors: Johanna Ulrike , Kusumah Epo Prasetya
Published: October 2023

Vulcan Subbasin is an area with a lot of oil and gas exploration where is located in the Bonaparte Basin, Northwest Australia. There is some formation identified as sandstone reservoir with clay content which is usually called shaly sand based on the screening between resistivity log and density log. Clay content caused lower resistivity log readings so the shaly sand reservoir is considered as non-reservoir. To overcome this, a method besides the conventional method was applied to analyze the petrophysical parameters of shaly sand reservoir, it was shaly sand method. Petrophysical analysis is an analysis of rock physical parameters such as shale volume, porosity, and water saturation based on well log data. In this study, petrophysical analysis was carried out in the Vulcan Subbasin using 35 well log data, including gamma ray log, resistivity log, neutron log, and density log for the conventional method and shaly sand method involved Stieber equation and Thomas Stieber plot. The results obtained from this study are the comparison of petrophysical parameter values and pay summary between the conventional method and the shaly sand method, also its relation to the shale distribution type. By applying the shaly sand method, the average shale volume has decreased, the average porosity has increased, the average water saturation has increased, the average net to gross has increased, the average net thickness has increased, and the average net pay has increased. Changes in the average value were caused by laminated-dispersed shale distribution type which is influenced by diagenesis and the depositional environment of the formation.

Published: October 2023

Many sensors in Optical domain allow for detection of hydrocarbons in oil spills study. However, high resolution laboratory and airborne imaging spectrometers have shown potential for quantification and characterization of hydrocarbon. Available methods in literature for quantifying and characterizing  hydrocarbons on these data relies mainly on shapes and positions of hydrocarbon key absorption features, mainly at 1.73 µm and 2.30 µm. Shapes formed by these absorption features are often influenced by spectral features of background substrates, thereby limiting the quality of results. Furthermore, multispectral sensors cannot resolve the shapes of key absorption features, a strong limitation for methods used in previous works. In this study, we present Hydrocarbon Spectra Slope (HYSS), a new spectra index that offers predictive quantification and characterization of common hydrocarbon oils. Slope values for the studied hydrocarbon oils enable clear discrimination for relative quantitative analysis of oil abundance classes and qualitative discrimination for common hydrocarbons on common background substrates. Data from ground-based spectrometers and Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) are resampled to AVIRIS, Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) and LANDSAT 7 Enhanced Thematic Mapper’s (ETM+) Full Width at Half Maximum (FWHM), in order to compute spectra slope values for hydrocarbon abundance /hydrocarbon-substrate characterization. Despite limitations of nonconformity of central wavelengths and/or band widths of multispectral sensors to key hydrocarbon band, statistical significance for both quantitative and qualitative analysis at 95% confidence level (P-value ˂0.01) suggests strong potential of the use of HYSS, multispectral and hyperspectral sensors as emergency response tools for hydrocarbon mapping.

Investigation of Groundwater Quality using Vertical Electrical Sounding and Dar Zarrouk Parameter in Leihitu, Maluku, Indonesia
Authors: Bahri Samsul , Ramadhan Aditya , Zulfiah
Published: October 2023

The goal of this research is to obtain information related to aquifer quality, including aquifer protection capacity, transmissivity, and aquifer thickness based on vertical electrical sounding (VES) data and Dar-Zarrouk parameter analysis. The research area is located in Leihitu District, Ambon with 8 measurement points. The Leihitu region is included in the geological map of the Ambon sheet, Maluku, which consists of Late Pliocene - Holocene lithology, specifically Ambon volcanic rocks, reef limestones, and alluvial deposits. The rock resistivity measurements and layer thickness information were obtained using the VES method and analyzed with IP2WIN software. Based on VES data, aquifer properties were identified using Dar-Zarrouk parameters. That parameter consisted of longitudinal conductance, transfer resistance, longitudinal resistivity, and transfer resistivity. Longitudinal unit conductance is applied to evaluate the protective capacity class of the aquifer, the transfer resistance is beneficial for analyzing rock type and aquifer transmissivity. Based on the Dark-Zarrouk parameters, the longitudinal conductance (S) ranged from 0.0278 to 5.1213 mho and was classified as moderate to good protective capacity. The high S value results from a thick layer of clay at the observation point. This area also has a high enough transverse resistance (T) and then if related to aquifer transmissivity, this area is classified as a good transmissivity aquifer, especially at VES 2, VES 5, VES 6, VES 7, and VES 8. If correlated to rock formations, areas with limestone and volcanic rocks have better transmissivity than areas with alluvial deposits.
Modelling the Spatial Distribution and Future Trends of Seawater Intrusion due to Aquaculture Activities in Coastal Aquifers of Nizampatnam, Andhra Pradesh
Authors: Manne Gopaiah , Das Iswar Chandra , Mahammood Vazeer
Published: October 2023

Coastal aquifers suffer from saltwater intrusion due to several natural and anthropogenic activities and they pose a severe problem in many coastal regions of India. Anthropogenic activities like saltwater aquaculture activities and salt pans are one of the major causes for saltwater intrusion into freshwater aquifers in coastal regions. Along with these activities, over-exploitation of fresh groundwater for domestic and agriculture purpose also leads to infiltration of saltwater into shallow freshwater aquifers. To address this effect, it is necessary to understand the spatial distribution and extent of the saltwater intrusion in coastal areas. In the present study, SEAWAT model is used to delineate the saltwater intrusion effect and predict the extent of saltwater intrusion resulting from anthropogenic activities in the Nizampatnam coastal area, Andhra Pradesh. The simulation was carried out for the period 2016 to 2018 revealing a change in the extent of the saltwater intrusion up to 2 km into the inland areas from the coast as well as in the vicinity of fishponds. Based on the hydrological conditions observed during the study period and leveraging the calibrated model, saltwater intrusion prediction was carried out for the next two decades. The results show that anthropogenic activities will lead to saltwater intrusion into freshwater aquifers up to 6 km into inland areas from coast at a rate of 200 m/year. Therefore, the sustainable management plans are essential for protecting the freshwater aquifers from the saltwater intrusion in the Nizampatnam coastal area.
Contributos para o estudo das orações adverbiais introduzidas por em vez de no PEC
Authors: Macário Lopes Ana Cristina
Published: October 2023

The aim of this paper is to characterize the subordinate adverbial clauses introduced by ‘em vez de’ in European contemporary Portuguese. In syntactic terms, these clauses are peripheral, loosely linked to the main clause, rejecting all focusing structures. A semantic-pragmatic hypothesis is put into test to explain this behaviour: the information expressed by the adverbial clauses is pressupposed. Two semantic sub-types of ‘em vez de’ clauses are thouroughly described: (i) those which contrast a factual situation with the speaker’s expectation and (ii) those which contrast a factual situation with a non-factual preferential alternative. A fine-grained analysis of the modal values involved is carried out, and, in a smaller scale, temporal and aspectual values are also taken into consideration.

We tested Portuguese children in the 4th grade (N=27) and college students (N=36), using a lexical decision task. The subjects saw the rime for 50 ms. Results show differences in the word processing, both for children and adults. This indicate that morphological information exert effects in the early stages of word processing.

This paper deals with the lexical variation on the denominations used by speakers of African countries where Portuguese is the official language (PALOPs), as answers from the semantic-lexical questionnaire of Brazil Linguistic Atlas, analyzing lexical varieties used by those Portuguese speakers to characterize concepts, since, by using a lexical expression to name something, are styling concepts according to their worldviews. This enquiry is part of a larger Project - of the Linguistic Variation, and Speech Discourse Processing: analysis and applications group (PROFALA1).
Variação Prosódica no Português Europeu: análise comparada de fenómenos de sândi vocálico
Authors: Nuno Paulino  , Sónia frota
Published: October 2023

In this article we examine three different hiatus resolution phenomena (Vowel Merger, Semivocalization and Back Vowel deletion) in five different urban regions in the north, centre and south of Portugal. These five regions show similarities with the Standard variety of European Portuguese: specifically lexical stress blocks Vowel Merger, whereas Semivocalization and Back vowel deletion allow stress in the second vowel. The geographic distribution of each phenomenon was also looked into and it was concluded that Semivocalization is far more frequent in the north than back vowel deletion, which is the preferred pattern in the south. Furthermore, all the phenomena are constrained by prosodic conditions, including prominence levels.
Estratégias discursivas de mitigação na sequência discursiva de pergunta-resposta: a justificação no contexto de entrevista
Authors: Almeida Carla Aurélia de
Published: October 2023

Taking as reference an oral corpus of narratives of life experience collected in interviews, we will analyse the question-answer sequence and the justification sequence. As a pre-sequence that prepares the act of question, anticipating possible objections from the interviewee, justification constitutes an argumentative strategy, developed by the interviewer, at the service of interactional achievement. We will also study the interviewees' answers followed by justification, specifically those at the service of the mitigation of epistemic values, representing a strategy of mitigation and softening what is being said in the propositional content of the answer, reducing the epistemic obligations of the interviewee.
Dialetologia e história da língua: sobre a génese e condicionamento de alguns traços das atuais variedades do Português
Authors: Maria José Carvalho
Published: October 2023

This paper aims to describe historically four phenomena which currently show dialectal or social variation, and whose diachronic development, seen in the geographical location of their documentary evidence, leads us to believe that, in other periods of Portuguese linguistic history, they were found more generally throughout the country, especially in more peripheral dialects. The study underlines the need for a historical and geo-sociocultural framework for any linguistic phenomenon that currently shows variation within Lusophone areas, thus emphasizing the importance of an interdisciplinary vision when describing such features.
Variação entoacional no Português do Brasil: uma análise fonológica do contorno nuclear em enunciados declarativos e interrogativos
Authors: Joelma Castelo  , Sónia Frota
Published: October 2023

In this paper we present a phonological analysis of the nuclear contour of declarative and interrogative utterances in Brazilian Portuguese, as spoken in 7 regions, along the Atlantic Coast - Paraíba, Sergipe, Bahia (North); Minas Gerais, Rio de Janeiro (Center), Santa Catarina and Rio Grande do Sul (South). Declaratives present a falling contour, with phonetic differences across varieties. As for interrogatives, more variation was found. Namely, two types of nuclear contours were observed: a rising contour in the North and a rising-falling in the Center-South. Unlike declaratives, the two interrogative patterns display a phonological continuum, in which the Center-Southern pattern spreads towards the North.
ELEMENTAL ANALYSIS OF PARTICULATE MATTER BY X-RAY FLUORESCENCE METHODS: A GREEN APPROACH TO AIR QUALITY MONITORING
Authors: Bilo Fabjola , Cirelli Paola , Borgese Laura
Published: October 2023

This review explores X-ray fluorescence (XRF) for elemental analysis of particulate matter (PM) for air quality monitoring. The introduction presents PM classification based on size and composition, covering various elemental analysis methods while highlighting the increasing interest in XRF due to its non-destructive, rapid, and green features. The fundamental concepts of XRF and the experimental configurations commonly used are discussed, focusing on Energy Dispersive X-Ray Fluorescence (EDXRF) and Total Reflection X-Ray Fluorescence (TXRF). PM sampling devices and substrate are described, with a specific emphasis on filtering membranes for EDXRF and reflecting substrates for TXRF. Sample preparation strategies and procedures are presented. Qualitative and quantitative analysis is described, with a particular focus on the calibration approaches implemented for PM. Finally, the challenges faced by XRF in becoming a recognized reliable analytical technique for PM analysis, comparable to other standardized techniques for PM filters analysis, while capitalizing on its green advantages.
Intermetallic compounds as oxygen evolving anodes for metal electrowinning : Electrochemical dealloying and effects of scale in practical electrochemistry
Authors: Williams David
Published: October 2023

Electrochemical dealloying has recently been highlighted as a promising technique for developing active electrodes for water electrosplitting. Intermetallic compounds of a base metal with passive film-forming element are effective oxygen evolution anodes for metal electrowinning. Cobalt-silicon alloys and titanium-nickel intermetallics are demonstrated as examples and related to the proposed paradigm of electrochemical dealloying. These systems illustrate the effects of scale in practical electrochemistry, where ‘scale’ has multiple meanings: the transition to practise; formation of surface deposits; and the evolution of the interface in extended use. In the case of cobalt-silicon alloys, the microstructure of the metal is critical. A highly porous surface layer is developed, within which the active phase is ‘nanostrands’ of cobalt metal in ‘nanoconfinement’ within a slowly-dissolving silicide matrix. Within the confined environment, a saturated solution of cobalt salt causes a salt film over the cobalt metal under which an oxygen-evolving cobalt anodic oxide is stabilised. In the case of TiNi, a nickel-rich surface forms over a thin titanium anodic oxide. Oxygen evolution occurs by field-assisted electron tunnelling to the surface nickel titanium oxide states. Field-driven ion migration both leads to these active states and leads to a slow dissolution of the metal. There is a useful range of composition between 51 and 55 wt% Ni (46 – 50 at %) which balances ductility against dissolution rate: excess titanium leading to a continuous phase of Ti2Ni results in a very brittle material; separation of TiNi3 leads to more rapid dissolution. In practise however, intrusion of oxygen during casting of large plates segregated Ti as the oxide Ti4Ni2O leading to separation of TiNi3 . The more rapid dissolution of this phase, in association with formation of MnO2 from Mn salts present in plant electrolyte, led in association with oxidation of cobalt salts to deposition of an adherent surface scale under which the solution became strongly acidic. The accelerated anode dissolution led to an under-scale of TiO2 which further increased acidification. Impractically rapid destruction of the anode resulted. The work illustrates how mass-transport and microstructure in the evolving interphase between electrode and electrolyte can interact in subtle ways important for practical application.
Oxidation-Responsive Supramolecular Hydrogel Based on a Simple Fmoc-Cysteine Derivative Capable of Showing Autonomous Gel–sol–gel Transitions
Authors: Shintani Yuki , Katagiri Hiroshi , Ikeda Masato
Published: October 2023

Aqueous soft matter, including supramolecular hydrogels capable of exhibiting stimuli–responsive macroscopic phase transitions, has attracted increasing attention for the exploration of functional soft materials. However, the investigation of supramolecular hydrogels that undergo autonomous and multiple macroscopic phase transitions (e.g., gel–sol–gel, sol–gel–sol) in response to the surrounding environment without repeated additions of stimuli has remained largely unexplored. In this study, we present the oxidation-responsive autonomous gel–sol–gel transitions of supramolecular hydrogels fabricated via the self-assembly of a simple fluorenylmethyloxycarbonyl (Fmoc)-protected, benzylated cysteine (Fmoc-CBzl). During the evaluation of the oxidation process of Fmoc-CBzl, we found that the oxidized products, two diastereomeric sulfoxides (Fmoc-CBzl-(R)-O and Fmoc-CBzl-(S)-O), exhibit significantly different self-assembly propensities under aqueous conditions. The difference in the self-assembly propensities and kinetics of self-assembly/disassembly may contribute to oxidation-responsive autonomous gel–sol–gel transitions. Notably, the chirality of sulfoxide has been largely overlooked and not effectively used to modulate supramolecular, self-assembled nanostructures.
Toward an understanding of glucose metabolism in radial glial biology and brain development
Authors: Andrews Madeline G , Pearson Caroline A
Published: October 2023

Decades of research have sought to determine the intrinsic and extrinsic mechanisms underpinning the regulation of neural progenitor maintenance and differentiation. A series of precise temporal transitions within progenitor cell populations generates all the appropriate neural cell types while maintaining a pool of self-renewing progenitors throughout embryogenesis. Recent technological advances have enabled us to gain new insights at the single-cell level, revealing an interplay between metabolic state and developmental progression that impacts the timing of proliferation and neurogenesis. This can have long-term consequences for the developing brain’s neuronal specification, maturation state, and organization. Furthermore, these studies have highlighted the need to reassess the instructive role of glucose metabolism in determining progenitor cell division, differentiation, and fate. This review focuses on glucose metabolism (glycolysis) in cortical progenitor cells and the emerging focus on glycolysis during neurogenic transitions. Furthermore, we discuss how the field can learn from other biological systems to improve our understanding of the spatial and temporal changes in glycolysis in progenitors and evaluate functional neurological outcomes.
