The article describes an approach to the expansion of the methodology for applying hydraulic fracturing in oil fields by adding the possibilities of 3D modeling with color imaging of the pore structure within productive intervals of the wells. As an applied example, the geological and geophysical section of the productive level of one of the wells in Moscudinskoye oil field with known data on the integrated interpretation of the results of well logging and microcomputer tomography was chosen. According to well-logging data, the productive reservoir in the analyzed area of the section is characterized by a high degree of heterogeneity. The tomography studies of a full-size core enabled to identify four lithotypes here with different pore structure features. The consideration of the identified reservoir heterogeneity, as well as the data on the thickness and other characteristics of reservoir properties of individual lithotypes which make up the section, allowed to significantly increasing the detail of the final geological model of the wellbore section. A distinctive feature of this final geological model is the use of the method of enlargement of the initial data array by adding intermediate values which were calculated theoretically. The visibility of the final geological model of the borehole walls is provided by color 3D imaging of the calculated data of the enlarged massif and gives an idea on the presence of areas with good and weak fluid conductivity on the lateral surface of the borehole walls. According to this model, the intrastratal transverse and longitudinal fluid-conducting “corridors” are observed in the circumwell zone that define the hydro-dynamic movements of natural and artificial fluids in the medium of productive reservoirs.

The literature materials available in recent years, as well as the results of the authors research on liquid-phase epoxidation of macro– and polycyclic bridged unsaturated hydrocarbons with the participation of homogeneous and heterogeneous catalytic systems and various oxidants–peroxacids, organic hydroperoxides, hydrogen peroxide and air oxygen have been summarized and analyzed. The activity and efficiency of homogeneous and heterogeneous catalysts are considered. It was revealed that homogeneous catalysts, as well as peroxoacids as oxidants, despite their high activity, show low productivity, which is due to a change in their ligand environment. The use of peroxoacids as reagents for epoxidation requires specific approaches in the technological implementation of the process. More promising in this direction are the studies on the epoxidation of polycyclic unsaturated hydrocarbons with the participation of heterogeneous catalysts and an environmentally friendly oxidizer - hydrogen peroxide. The preparation on the basis of nanostructured and other types of carbon and oxide materials, immobilized catalytic systems have been studied to much lesser extent. It can be assumed that this direction will be developed in the future.

Las mujeres mariscadoras en Galicia: profesionalización y compromiso medio-ambiental
Authors: González -Laxe Fernando
Published: January 2024

El marisqueo es una actividad tradicional. La mayor parte del trabajo se efectúa con métodos de producción elementales en los bancos de arena de las zonas inter-mareales a tiempo parcial. Fue una actividad de subsistencia realizada, fundamentalmente y durante años, por mujeres. Los productos extraídos poseían una demanda reducida y su valor en el mercado era escaso. Desde mediados del siglo XX las administraciones públicas dictan medidas de ordenación a fin de regular y evitar la sobre-explotación de las áreas marisqueras. El marisqueo constituye en la actualidad la principal fuente de riqueza de las personas que la realizan. Las mujeres han sido claves en la demanda de profesionalización, reforzando el empoderamiento y la participación activa en la toma de decisiones. Más dicho proceso está conllevando, paralelamente, una tendencia hacia la masculinización. Se analiza el papel de las mujeres mariscadoras desde el enfoque económico y ambiental, vinculando su trabajo con los Objetivos de Desarrollo Sostenible; dando cuenta de los compromisos y tareas relacionadas con el mismo. Los resultados obtenidos prueban que las mariscadoras cumplen con la mayoría de ellos, asumiendo los principios de sostenibilidad y responsabilidad.
La Violencia y lo Virtual en la Clínica Psicoanalítica Desde el Mito de Tiresias
Authors: Barrón Soto Héctor Sixto , Miranda Aldana Rita Marcela
Published: January 2024

La violencia es constitutiva del sujeto, tanto que no hay sujeto sin violencia, esto es, de aquello que irrumpe de un afuera en el que se establece al gran Otro como impositor del significante amo: guía del deseo también inscrita desde esa exterioridad. Ni significante ni deseo son, propiamente, pertenencias del sujeto, sino apropiaciones desde el Otro. ¿Qué es entonces lo que podría sugerirse como producción del sujeto? Aquello que resulta como efecto de la voz del Otro en el lenguaje, y algo de esa producción se denomina lo virtual, no como un fenómeno, sino como una intensidad que guarda una singularidad frente a la pulsión y a la potencia, y por ello se distingue de lo posible y del destino. En nuestros días es imprescindible atender no sólo la presencia de la violencia y de lo virtual por separado en el sujeto, sino observar sus vinculaciones entre sí para desentrañar en la interpretación psicoanalítica sus expresiones en los grupos sociales.

Published: January 2024

The cloud computing transforms information technology by offering end users simulated, flexible resources on demand that require fewer resources and facilities giving them greater flexibility. These materials are delivered over the Internet using predefined networking protocols, regulations, and styles, and they are overseen by various management groups. There are flaws and vulnerabilities in the underlying technology and legacy protocols that could allow an attacker to get access. A recent assessment of the literature led to the conclusion that most intelligence algorithms have a number of complex issues, including a high false prediction rate, difficulty classifying threats, high processing costs, and system load. Hence, the proposed work aims to develop an innovative and lightweight Augmented Stacking Polynomial Optimized Tool (ASPOT) for strengthening the cloud-IoT system security against modern cyberattacks with a accuracy of 99%. The current study uses the lightweight Deep Augmented Preprocessing Model (DAPM) to clean and normalize the input cyber-attack dataset by executing transformation and normalization operations on it. Furthermore, the Binary Sand Cat Swarm Optimization (BSCSO) technique is utilized to identify the most significant and relevant features of the normalized dataset in an optimal manner. Moreover, the class of assaults is promptly and precisely identified from the given data by applying the Deep Stacking Polynomial Learning Network (DSPLN) technology. The effectiveness and results of the proposed ASPOT method are analysed with the use of current cyber-attack statistics and a variety of assessment metrics.

Published: January 2024

An inverter is the main component of an on-grid solar system. It converts DC power from solar PV to AC power to serve the electric load. Besides, it is used to find the maximum power point tracking and regulate the electric power from the main power and backup. This research discusses the development of an online inverter 40 kW monitoring system on the 38 kWp rooftop solar system at Pamulang University. The existing inverter monitoring system is by iSolarCloud application. This monitoring system can be accessed from the local area by scanning a QR code and Bluetooth connection. This system provides several output parameter information of the inverter, such as voltage, current, and power generation. The SCADA Haiwell has been used to construct the monitoring system. This system consists of the Programmable Logic Controller (PLC) Haiwell AC10S0R, Human Machine Interface (HMI) C7S-W, and Haiwell cloud application. The PLC reads the data from the input and output inverter by Modbus TCP/IP communication. The result of the monitoring system provides more parameters on both sides of the inverter input and output data. The Input side parameters include DC voltage, current, and DC power. The Output side parameters include AC voltage, current, grid frequency, active power, reactive power, daily yield power, total yield power, and efficiency of the inverter. The system's accuracy has been validated by comparing the HMI data, SCADA Haiwell Cloud and iSolarCloud readings. From the testing, this monitoring system is valid for monitoring the inverter performance online (mobile phones or PC).
Preliminary Evaluation of Photoprotective Potential in Flowers of Osbeckia octandra (L.) DC. for Development of Herbal Sunscreen Formulations
Authors: Liyanaarachchi C , Napagoda M , Witharana S , Jayasinghe L
Published: January 2024

Introduction: Excessive exposure to ultraviolet (UV) radiation of the solar spectrum is often linked with the onset of conditions like inflammation, photoaging, immunosuppression, hyperpigmentation, and photocarcinogenesis. Although synthetic sunscreens have emerged as protectants against this harmful UV radiation, there is an increasing demand for sunscreens of herbal origin, which are believed to have low side-effect profiles in comparison to their synthetic counterparts. In order to cater for this need, the present study aimed at developing herbal sunscreen formulations from flowers of Osbeckia octandra DC, a purple-coloured wildflower widely distributed across different geographical regions in Sri Lanka.
Methodology: The UV filtering potency and subsequently, the sun protection factor (SPF) in the methanolic extract of O. octandra was initially determined. Thereafter this extract was incorporated into the aqueous cream base at 25%, 50%, and 75% (w/w) and the SPF values and photostability of the prepared formulations were evaluated.
Results: The initial SPF value of the crude extract (39.91 ± 1.93) had hardly changed even after incorporating it at 75% into the aqueous cream base. This 75% formulation surpassed the other two formulations and the commercial sunscreen (positive control) in terms of the higher SPF and broader spectrum of UV absorption. Its SPF value altered only slightly during the storage for 21 days in light or dark conditions and was photostable.
Conclusion: Our preliminary observations demonstrated the appropriateness of O. octandra for the formulation of herbal sunscreens at the commercial stage.

Authors: Molise Habasisa Vincent , Kola Malose Isaac , Ntshangase Mohammed Xolile
Published: January 2024

This study sought to examine the challenges experienced by Economics and Management Sciences (EMS) teachers during Continuous Professional Teacher Development (CPTD) in the Thabo-Mofutsanyane Education District, South Africa. This study adopted a relational leadership theoretical framework, which supports the need for school leadership to prioritize relationships when implementing CPTD. This study used a qualitative research approach, which is more interested in analyzing data with the aim of finding the truth than a statistical narrative. Within this study, a case study methodology involving six participants was selected through purposive sampling and snowballing from one school in the Thabo-Mafutsanyane district. The collected data through semi-structured interviews with those six participants was subjected to thematic analysis. This study is important as it shows that healthy school relations are gravely significant for the success of CPTD and that there is a dire need for subject advisors to harmoniously work together with teachers to ensure CPTD programs are effectively implemented.

James Webb Space Telescope Spectra of Cold Brown Dwarfs are Well-reproduced by Phosphine-free, Diabatic, ATMO2020++ Models
Authors: Leggett S. K. , Tremblin Pascal
Published: January 2024

James Webb Space Telescope (JWST) mid-infrared spectra of cold brown dwarfs (BDs) are becoming available. In Leggett & Tremblin we demonstrated that an ATMO2020++ synthetic spectrum provided an excellent fit to the first published spectrum. Here we show that these models can reproduce the 1–14 μm spectra of BDs with a range of effective temperature: 350 ≤ T
eff K ≤ 500. A grid of these models, which include disequilibrium chemistry and non-adiabatic pressure–temperature profiles, is available. In addition, a number of models without phosphine were calculated, as PH3 is absent in the JWST data. Two of the six BDs studied are particularly interesting; one appears to be a young low-mass BD, the other is best fit as a binary. More complete analyses will be possible with an extended model grid, and with additional JWST data. The ATMO2020++ models are recommended for analyses of all BD data.
A new subterranean species of Entomoculia Croissandeau, 1891 from the Canary Islands, Spain (Coleoptera, Staphylinidae, Leptotyphlinae)
Authors: Hernando Carles , López Heriberto
Published: January 2024

The genus Entomoculia Croissandeau, 1891, is the only representative of the subfamily Leptotyphlinae present in the Canary Islands and is composed by only two species: E. (Stenotyphlus) canariensis Outerelo, 1982, from La Gomera and E. (Stenotyphlus) lauricola Outerelo & Hernández, 1989, from Tenerife, both found in deep soil (= endogean) habitats. In this paper, we describe Entomoculia (Stenotyphlus) vulcanicasp. nov., the third Canarian species of the genus, which is reported for the first time from Gran Canaria and has been found in the mesovoid shallow substratum “MSS”. This new species has some of the characteristics that are specific to Canarian species of the genus Entomoculia, such as the lack of a denticle or spiniform process on the male metatrochanters. However, it is a remarkable species as it is the only known species of the genus with a tridentate labrum, as the labrum is monodentate in the species so far known from Canary Islands and bidentate in non-Canary species. We provide a key to Canarian species and illustrations of the habitus and the primary and secondary sexual characters of the male. We also describe the sampling techniques used and provide detailed information on habitat characteristics and associated arthropod fauna.
Microneedle and drug delivery across the skin: An overview
Authors: Hamdan Iman
Published: January 2024

The skin offers a route of administration with numerous advantages. However, one of the major limitations of this route is the limited number of drugs that possess the ideal physicochemical properties to passively diffuse through the skin barrier. Today, microneedle (MN) technology proved to be superior in the field of drug delivery. MN arrays are devices that consist of micron-sized projections which pierce the stratum corneum (SC), the main barrier for drug delivery across the skin. MN technology has the potential to provide a localised drug delivery with minimal toxicity and expand the range of drugs for transdermal and intradermal delivery. In this comprehensive review, MN technology was thoroughly discussed. Meeting regulatory standards and large-scale production is essential to advance MN technology into a cost-effectiveness commercial scale.
A new genus of soft coral (Octocorallia, Malacalcyonacea, Cladiellidae) and three new species from Indo-Pacific coral reefs
Authors: McFadden Catherine S. , Benayahu Yehuda , Samimi-Namin Kaveh
Published: January 2024

Molecular systematic studies of the anthozoan class Octocorallia have revealed widespread incongruence between phylogenetic relationships and taxonomic classification at all levels of the Linnean hierarchy. Among the soft coral taxa in order Malacalcyonacea, the family Alcyoniidae and its type genus Alcyonium have both been recognised to be highly polyphyletic. A recent family-level revision of Octocorallia established a number of new families for genera formerly considered to belong to Alcyoniidae, but revision of Alcyonium is not yet complete. Previous molecular studies have supported the placement of Alcyonium verseveldti (Benayahu, 1982) in family Cladiellidae rather than Alcyoniidae, phylogenetically distinct from the other three genera in that family. Here we describe a new genus, Ofwegenumgen. nov. to accommodate O. verseveldticomb. nov. and three new species of that genus, O. coronalucissp. nov., O. kloogisp. nov., and O. collisp. nov., bringing the total number of species in this genus to four. Ofwegenumgen. nov. is a rarely encountered genus so far known from only a few locations spanning the Indian and western Pacific Oceans. We present the morphological characters of each species and use molecular data from both DNA barcoding and target-enrichment of conserved elements to explore species boundaries and phylogenetic relationships within the genus.

Effectiveness of Blended Learning for Civil Engineering Students’ Performance during COVID-19: A Case Study of a Rural University in South Africa
Authors: Phesa Mbulelo
Published: January 2024

In this study, the effectiveness of blended learning on the learning of civil engineering students during the COVID-19 pandemic was evaluated at a rural university in the Eastern Cape Province of South Africa. The imposition of lockdown due to the global spread of COVID-19 left educational institutions with no choice but to find alternative methods of teaching and learning. Students were sent home in order to control the spread of the virus. Secondary data were used to examine the students’ performance in 2019, prior to the COVID-19 pandemic, and in 2020, during the COVID-19 pandemic. Furthermore, primary data was obtained through questionnaires to assess the students’ opinions on blended learning. The Mann-Whitney U test was used to determine the extent of the difference in students’ performance before and during COVID-19. Descriptive analysis results indicated the superiority of blended learning over face-to-face teaching methods, with blended learning achieving a 67% success rate compared to the 33% achieved by face-to-face methods. Similarly, the Mann-Whitney U test also showed a significant difference between blended and face-to-face teaching methods. In contrast to the descriptive analysis and Mann-Whitney U test, students’ sentiments indicated otherwise. 80% of students neither agreed nor disagreed with blended learning methods as a preference over face-to-face teaching methods. The results of this study demonstrated the effectiveness of the teaching methods used during the COVID-19 pandemic. Furthermore, it revealed and, further, showed the sentiments of students regarding the teaching methods employed during this period.
The Impact of Online Learning during the COVID-19 Pandemic on Language Learning Strategies, Proficiency, and Enjoyment among Thai EFL Students
Authors: Toomnan Parichart
Published: January 2024

Amidst the COVID-19 pandemic, individuals worldwide found themselves compelled to adapt to unforeseen circumstances. An integral part of this adjustment was the transformation of conventional instructional methods, shifting from traditional classroom-based learning to the realm of online education. In this new educational landscape, online learning has emerged as the only avenue for both educators and learners to sustain their academic journeys. The objective of this study was to examine potential changes in the application of language learning strategies (LLSs) in the context of online English learning amidst the COVID-19 pandemic. The study also aimed to explore whether these variations were influenced by individuals’ levels of language proficiency and their level of enjoyment of learning English. If any variations were identified, the study aimed to analyze the specific patterns that emerged. The study included 205 students who were enrolled in a public university in northeastern Thailand. Data collection involved administering both the LLS questionnaire and the enjoyment of the English learning questionnaire. Quantitative data analysis involved the use of descriptive statistics, ANOVA, and Chi-square tests. The study revealed significant variations in the frequency of overall strategy utilization based on two variables: language proficiency and individual enjoyment with the process of learning English. While there were no significant variations in overall strategy usage based on language proficiency, notable differences were observed based on their level of enjoyment of learning English. In terms of distinct categories, significant differences were observed in the utilization of LLS within the metacognitive (MET) and affective (AFF) categories, especially concerning language proficiency. Moreover, substantial variances were evident across all six categories—memory (MEM), cognitive (COG), compensation (COM), MET, AFF, and social (SOC)—in the level of satisfaction derived from the process of learning English.
Adjusted Locality, Antiracist Aims
Authors: Threatt Brittney , Carroll Charles
Published: January 2024

Following the police murders of Breonna Taylor and George Floyd, every sector of the country was wracked with the truth of their insufficient racial equity. In higher education, this resulted in solidarity statements and diversity action plans. Many of our colleagues in higher education across the United States now lament a waning energy around ensuring institutional equity, a trend which has been exacerbated by legislation such as Florida's Stop WOKE Act. These efforts toward equity are additionally challenged by ever-changing avenues of support, limited staffing, and the finite bandwidth of those staff who do commit. This chapter will address the limitations and opportunities of DEI initiatives run by a small staff (in this case a graduate student and writing center director) in a larger institution (in this case a university writing center). The chapter will also propose methodological and pedagogical shifts to further the longevity of community programs and partnerships.

Published: January 2024

Flash floods are natural disasters that significantly threaten communities and infrastructure worldwide. Flash flood early warning systems (FFEWS) have been developed to mitigate the negative impacts of flash floods. These systems rely on monitoring and forecasting weather conditions and providing timely warnings to potentially affected communities. However, their effectiveness in reducing disaster risks needs to be better established. This chapter aims to critically review flash flood early warning systems, examining their strengths, limitations, and challenges associated with their implementation and proposing an improved framework and algorithm for an early warning system to mitigate some of the challenges encountered in previous systems. By delving into the current state of these systems, their components, and the factors influencing their effectiveness, this chapter seeks to enhance our understanding of EWS and contribute to developing more robust and efficient strategies for mitigating the impacts of flash floods.

Published: January 2024

This chapter aims to understand which type of format (image or video) has more impact on interaction. To assess the effect of the video or image format on interaction campaigns, important metrics were selected to analyze interaction campaigns: reach, impressions, CPM, interaction results, interaction rate, cost per interaction with the post, comments on posts, reactions on posts, saved posts, and shares of posts. This study is qualitative, based on information from Facebook Business Manager, where through the data from the campaigns developed it is possible to reach conclusions regarding Facebook Ads interaction campaigns in video and image formats. Tables were drawn up to interpret the results, using comparisons between campaigns to understand which format achieves the best results in terms of engagement. The results show that the video format has better results in terms of reach, impressions, CPM, interactions, and cost per interaction with the publication. The image format shows better results in terms of comments on posts, reactions, saved posts, and shares of posts.

With the increasing diffusion of technologies and the use of the Internet, we are witnessing a rapid growth of cyberspace. This becomes a new means of communication in which, with the use of the Internet, rapid exchanges of information are possible in the context of commercial exchanges between consumers and sellers or companies. With the integration of the internet into marketing, we are witnessing changes from transactional marketing to relationship marketing. It becomes possible to segment the market more closely, understand the online consumer, and focus on personalisation. Since the objective is to satisfy consumer needs, the authors will address issues related to new communication strategies that have been implemented in the scope of Web marketing, starting from personalisation to satisfaction by the consumer.
Internal Communication and Happiness at Work
Authors: Costa Natália , Costa Marisol
Published: January 2024

Today, change and challenges are growing daily for managers. Having the ability to adjust quickly and retain talent to ensure the achievement of objectives and competitive advantage is critical. Internal communication is an internal practice that can be used strategically by the manager to improve several advantages for the employees and the organizations. Internal communication corresponds to all the ways of transmitting information, ideas, or emotion from different channels, like intranet, social media, and several others. Happiness at work is a powerful strategy that brings involved and committed employees to the organizations. This is a subjective construct in a way that depends on individual judgment. The authors develop a conceptual study that seeks to establish a relationship between IC and happiness at work. Both constructs were explored individually and listed the advantages. A final section was added to explore the relationship between the constructs, essentially through the advantages of both constructs.

Technology has changed the forms and means of advertising. With the rise of personalized online advertising, it becomes appropriate to explore the perceptions and concerns of Generation Z in the context of greater ease and proximity to consumption. With strong technological capabilities, those young consumers represent a strong buyer segment in the digital market. This chapter presents the results of a survey based on a questionnaire addressed to Generation Z. Based on a sample of 408 Portuguese university students, the results of the study highlight the high perceptions of attitude, utility, and value, as well as the privacy concerns that these associate with personalized online advertising. Given the lack of identified studies for the Portuguese case, this study contributes to a greater knowledge of Generation Z consumers. It is also expected to help companies improve their online advertising strategies targeted at customers with the technological skills characteristic of this generation.
A Re-Examination of Micro Learning Concepts, Theories, and Its Application to Language Acquisition
Authors: Ikeguchi Cecilia B.
Published: January 2024

Theoretical and practical research conducted on microlearning is reviewed to show the vast extent of its application on various instructional contexts and to help understand its dynamics. Two established theories assumed to be theoretical foundations of microlearning are examined in relation to reinforcement and feedback, two pivotal concepts in learning. Reasons for the dearth of materials on microlearning use in face-to-face or blended instructions compared to the substantial evidence demonstrating its application to other fields are examined. Finally, techniques on microlesson design are suggested based on a recognition of the essential theories in designing language microlessons grounded in theory and research.
Evaluating Microlessons in Asynchronous Learning Through a Novel Instructional Framework
Authors: Coker David C.
Published: January 2024

Microlessons have existed since the 1960s, but COVID-19 caused a major shift toward online and remote education. Many online platforms, from Khan Academy to massive open online courses (MOOCs) to proprietary systems, transformed overnight with a large increase in enrollment. While some theoreticians and researchers claimed microlessons were unsuitable for all learning, the conceptual framework offers a stark disagreement: All curriculum and instructional planning would benefit from a shift to micro-lessons. The conceptual framework for asynchronous learning stems from educational psychology, resilience, attention span, and social interdependence. The evaluative framework focuses on instructional development as opposed to curricular theory and resources, based upon Coker's methods to improve student learning. Architecture, delivery, and evaluation guide the analysis and planning of instruction.
Creation of Digital Micro-Lessons in the ELE Classroom
Authors: García Conesa Isabel María
Published: January 2024

This chapter focuses on the use of the micro-story as a real language sample in a group of foreign adult learners in a situation of linguistic immersion at the A2 level to enhance the development of basic communicative skills, while encouraging the appreciation of literature in the target language and creative production by the learners. By combining the creative writing activity with the implementation of technological tools, students are offered the opportunity to engage in a comprehensive learning process involving written production in the target language and the underlying processes of interaction, planning, and creation, together with the use of technological applications to enhance the narrative content and aesthetic aspect of the micro-stories. A proposal is made that includes a series of enabling activities aimed at bringing students closer to the reading and analysis of micro-stories and their characteristics, while leading students to the final task of written production: the creation of digital micro-stories in Spanish.
Micro Lessons Approach in Management Education to Develop Graduate Attributes
Authors: Baporikar Neeta
Published: January 2024

Management education has always relied on applied and learner-centered approaches to ensure that the right graduate attributes are acquired and the students are industry-ready when they graduate. The various teaching methods include case studies, role play, scenario building, and presentations that have focused on a student-centered approach to meet the learning objectives but may not have been necessary for the form of micro-lessons. Hence, adopting a qualitative approach, the aim of this chapter is to delve into the current scenario of teaching practices in management education and deliberate on the micro lessons approach in management education to develop graduate attributes. It aims at optimizing micro-lessons practice in management education programs. It suggests strategies that could assist management students to become better critical thinkers and problem solvers rather than mere rote decision makers by developing proper graduate attributes which are the imperative competencies to solve real-world complex problems.
