Moonie Resurrection
Authors: Kovach Stephanie ,   Bridgeport Energy
Published: September 2022

Moonie, Australia’s first commercial oil field, was discovered in 1961 and 60 years hence, is on track to be Australia’s first carbon capture, utilisation and storage (CCUS) project. Carbon utilisation involves enhanced oil recovery (EOR) technology, with the injection of CO2 (CO2-EOR) into the Precipice Sandstone primary oil reservoir. Since acquiring Moonie in late 2016, Bridgeport has completed core and PVT analyses and reservoir modelling studies, which indicate that the field is an excellent candidate for CO2-EOR. Successful history matching of the field as part of reservoir simulation modelling of the cumulative 25 mmbbls of historic production provides confidence of the estimate of the original oil in-place (OOIP). Further technical review to estimate the current and ultimate (post-CCUS) residual oil saturations will inform the likely EOR efficiency. This is an important parameter for predicting expected tertiary oil recoveries from the injection of CO2 into the Precipice Sandstone. A supply of anthropogenic CO2 is expected to be sourced from a post carbon capture (PCC) facility to be installed at the nearby Millmerran coal-fired power station. The initial pilot project at Moonie involves the injection of at least 60,000 tonnes/annum into an existing Moonie oil well with enhanced oil production from an encompassing array of up to 6 production wells. In addition, the pilot will demonstrate that significant volumes of CO2 can be stored safely in Moonie’s secure, structural trap.

Objective: To investigate the correlation of HRCT findings with pulmonary metabolic activity in the corresponding regions using 18F-FDG PET/CT and inflammatory markers in patients with systemic sclerosis (SSc)-associated interstitial lung disease (ILD). Methods: This was a cross-sectional study involving 23 adult patients with SSc-associated ILD without other connective tissue diseases. The study also involved 18F-FDG PET/CT, HRCT, determination of serum chemokine levels, clinical data, and pulmonary function testing. Results: In this cohort of patients with long-term disease (disease duration, 11.8 ± 8.7 years), a nonspecific interstitial pneumonia pattern was found in 19 (82.6%). Honeycombing areas had higher median standardized uptake values (1.95; p = 0.85). Serum levels of soluble tumor necrosis factor receptor 1, soluble tumor necrosis factor receptor 2, C-C motif chemokine ligand 2 (CCL2), and C-X-C motif chemokine ligand 10 were higher in SSc patients than in controls. Serum levels of CCL2-a marker of fibroblast activity-were correlated with pure ground-glass opacity (GGO) areas on HRCT scans (p = 0.007). 18F-FDG PET/CT showed significant metabolic activity for all HRCT patterns. The correlation between serum CCL2 levels and GGO on HRCT scans suggests a central role of fibroblasts in these areas, adding new information towards the understanding of the mechanisms surrounding cellular and molecular elements and their expression on HRCT scans in patients with SSc-associated ILD. Conclusions: 18F-FDG PET/CT appears to be unable to differentiate the intensity of metabolic activity across HRCT patterns in chronic SSc patients. The association between CCL2 and GGO might be related to fibroblast activity in these areas; however, upregulated CCL2 expression in the lung tissue of SSc patients should be investigated in order to gain a better understanding of this association.
Learning Dialogue from Jesus: A Reflective-Explorative Study of John 4:7–21 on Interfaith Encounters
Authors: Yosia Adrianus
Published: September 2022

This article discusses an explorative proposal for inter-faith dialogue based on the life of Jesus amid the development of religious and tribal diversity in the city in Indonesia. The rising migration and urbanization will bring diversity to a new height in Indonesia. Hence, dialogue is a must amid the irresistible context. This proposal for dialogue will be based on Kevin J. Vanhoozer's dramatic method through the fusion of horizons which proposes how to apply biblical passages to everyday life. The reflective-explorative study of John 4:7–21 resulted in three recommen­da­tions as a form of horizon fusion in the context of ethnic and reli­gious pluralism in the city, namely: the dialogue of reconciliation, the dialogue of friendship, and the dialogue of theology.

Noise is something that can be annoying. A silencer is a tool to reduce unwanted sound. This study aims to obtain the matrix characteristics of the fiber arrangement pattern on sound attenuation and the ratio of the composite material mixture. The method used in this research is to vary the ratio of flinkote oil mixtures 70%: 30%, 60%: 40%, 50%: 50%, as well as variations in the matrix pattern of coconut fiber composition with parallel matrices, straight oblique cross, how to make composites with how to spray flinkote oil onto the fibers using a spray gun. The analysis of the research is the reduction of the sound produced. The ratio of the mixture and the matrix of the fiber arrangement pattern affects the resulting sound reduction value. The results showed that the flinkote oil mixture ratio of 60%: 40% resulted in the highest reduction value of 4.96%, for the lowest results found in the ratio of flinkote oil mixture 50%: 50% fiber with a noise reduction value of 4.24%. The results of the analysis show that the ideal mixture occurs in composites of 60%: 40%, so that the flinkote oil can bind the fibers sufficiently and the composites are porous, in the 50%: 50% composites there are strains because the flinkote oil is unable to bind the fibers. In the fiber arrangement pattern matrix, there is the highest noise reduction value in the parallel matrix, namely 4.96%, for the lowest result is in the straight-sloping matrix with a reduced value of 3.90%, the analysis results in the parallel matrix have good noise wave propagation, because In the parallel matrix there is no wave interference phenomenon, resulting in parallel propagation of noise waves, in the straight-sloping matrix there is an interaction phenomenon between incoming waves and waves called interference so that noise waves increase and result in a low noise reduction level.

Introduction. The article is a logical continuation of the authors' work on the study of the effectiveness of the inclusion of the space segment, in particular the satellite communication system, in the control loop of the aircraft. The satellite communication system allows you to provide a radio signal coverage of a given territory at any time. This can be both local and global coverage of the globe. Methods. However, it is necessary to find such a structure and parameters of the orbits of the grouping of the communication and data relay system as the main structural and functional element for transmitting control commands that will ensure the effective performance of the control and guidance tasks in flight at any time in any environment. In the article, expressions are obtained for calculating the radio visibility time of the studied objects during the movement of a mobile target, and an expression is derived for calculating the probability of bringing control information to the aircraft during its flight. The analysis of the main characteristics that determine the quality of object management is given. Due to the high complexity, and sometimes impossibility, of calculations and the stochastic nature of both the process itself and the influencing factors on the aircraft, the study suggests using the simulation method as a tool for calculating the quantitative characteristics of the objective function – the probability of delivering command and control information from the com& mand post via a satellite communication system to the means of delivery and defeat for the implementation of correction of the incoming trajectory and following the movement of the mobile target. The analysis and conclusion of the outcome modeling operators and the evaluation of the efficiency indicator are given. And also a look at the application of such a method of statistical tests as the Monte Carlo method in simulation modeling is given. The general relations for this method are given, its positive aspects and the essence of its application in the study of finding a variant of the strategy for using a satellite communication system are considered, as well as the justification of a suboptimal variant of the composition, structure and characteristics of the orbital grouping under study in relation to the specifics of the process of targeting a delivery vehicle and hitting a mobile target.

Introduction: the increasing capabilities of modern complexes with unmanned aerial vehicles and their widespread use, when performing reconnaissance and reconnaissance-strike tasks, has led to an unprecedented level of counteraction from enemy complexes and systems, which is defined by the concept of information technology conflict. Purpose: the purpose of the study is to determine the estimated indicators that make it possible to determine in numerical terms with what degree of efficiency a particular task assigned to complexes with unmanned aerial vehicles is being solved. Among the performance indicators of complexes with unmanned aerial vehicles, generalized, private, system and final indicators are distinguished. In this paper, we will consider particular indicators characterizing the information and control system of complexes with unmanned aerial vehicles as a mobile packet radio communication system for special purposes in the conditions of information and technical influences from the enemy. Results: the classification of the most important tactical and technical indicators characterizing the functioning of the information management system of complexes with unmanned aerial vehicles is proposed, the main and promising methods of information and technical impacts and the types of technical intelligence preceding them are shown. The basic concepts are given, the formulaic expressions of the requirements for information and control systems are defined, such as: security, efficiency (timeliness), reliability, stability, noise immunity, noise immunity, technical reliability, secrecy (intelligence protection), cyber resistance, imitability, survivability. Practical relevance: the use of private indicators will allow us to switch to the use of generalized indicators (convolutions, objective functions or quality functionals), which in turn will help to get more general ideas about the effectiveness of control systems of complexes with unmanned aerial vehicles, including when organizing their group interaction.

Published: September 2022

Introduction: IMT2020 (5G) networks can significantly improve the performance of previous generation mobile communication systems in terms of improving broadband multiple access (eMBB – enhanced Mobile Broadband) and providing ultra-reliable low-latency communication (ULLRC – Ultra Low Latency Rellable Communication). The purpose of the work is to review and comparative analysis of multiple access technologies for promising mobile communication networks, which are based on OFDM. Result: The general principles of signal generation and processing when using variants of signals with OFDM using various methods of digital filtering of subcarrier frequencies are considered. For those OFDM options where a cyclic prefix may not be used (FBMC, UFMC), the possibility of increasing the information transfer rate is controversial, since the impulse responses of filters, for example, with FBMC, significantly exceed the duration of information signals, which increases intersymbol interference. Practical significance: The analysis of the general principles for constructing devices for generating and processing physical layer signals for OFDM variants with various methods of additional digital filtering of subcarrier frequencies shows that in all cases there is a significant complication of digital algorithms for generating and processing signals with a practical absence or in some cases a small gain (not more than (0.5&0.8) dB in relation to signal/noise) by the magnitude of the error per information bit. Based on the results of computer simulation, it is shown that OFDM technology and its variants do not allow obtaining breakthrough solutions in the field of physical layer signal characteristics for 5G and 6G networks, and alternative options for building group signal structures should be considered.

Starting from a question, why the behavior of most students comes out of good behavior while having understood moral education? This is because morality is only given seminars, notified, informed, not accustomed to, trained and given examples. Ibn Miskawaih emphasizes that behavior must be familiarized and trained, as is the case with tri-success guidance in which there is an alim (religious understanding) the orientation is understanding of basic obligations such as holy-unclean, lawful-haram and others, wise the orientation is good character, polite, and courteous in situations and conditions, while independent orientation is not relying on other people in any case, thus it must be familiarized, trained and given an example not just being told, informed and in seminars all oriented to the goals of Islamic education. Descriptive qualitative research method, this is carried out to build knowledge through understanding and discovery, the analysis used is data reduction, data presentation, drawing conclusions.
Towards the quantification of cybersecurity footprint for SMBs using the CMMC 2.0
Authors: Levy Yair , Gafni Ruti
Published: September 2022

Organizations, small and big, are faced with major cybersecurity challenges over the past several decades, as the proliferation of information systems and mobile devices expand. While larger organizations invest significant efforts in developing approaches to deal with cybersecurity incidents, Small and Medium Businesses (SMBs) are still struggling with ways to both keep their businesses alive and secure their systems to the best of their abilities. When it comes to critical systems, such as defense industries, the interconnectivities of organizations in the supply-chain have demonstrated to be problematic given the depth required to provide a high-level cybersecurity posture. The United States (U.S.) Department of Defense (DoD) with the partnership of the Defense Industry Base (DIB) have developed the Cybersecurity Maturity Model Certification (CMMC) in 2020 with a third-party mandate for Level 1 certification. Following an outcry from many DIB organizations, a newly revised CMMC 2.0 was introduced in late 2021 where Level 1 (Fundamental) was adjusted for annual self-assessment. CMMC 2.0 provides the 17 practices that organizations should self-assess. While these 17 practices provide initial guidance for assessment, the specific level of measurement and how it impacts their overall cybersecurity posture is vague. Specifically, many of these practices use non-quantifiable terms such as “limit”, “verify”, “control”, “identify”, etc. The focus of this work is to provide SMBs with a quantifiable method to self-assess their Cybersecurity Footprint following the CMMC 2.0 Level 1 practices. This paper outlines the foundational literature work conducted in support of the proposed quantification Cybersecurity Footprint Index (CFI) using 26 elements that correspond to the relevant CMMC 2.0 Level 1 practices.
Handling of “unknown unknowns” - classification of 3D geometries from CAD open set datasets using Convolutional Neural Networks
Authors: Schmidt Georg , Stüring Stefan , Richnow Norman , Siegert Ingo
Published: September 2022

This paper refers to the application of Convolutional Neural Networks (CNNs) for the classification of 3D geometries from Computer-Aided Design (CAD) datasets with a large proportion of unknown unknowns (classes unknown after training). The motivation of the work is the automatic recognition of standard parts in the large CAD-based image data set and thus, reducing the time required for the manual preparation of the data set. The classification is based on a threshold value of the Softmax output layer (first criterion), as well as on three different methods of a second criterion. The three methods for the second criterion are the comparison of metadata relating to the geometries, the comparison of feature vectors from previous dense layers of the CNN with a Spearman correlation, and the distance-based difference between multivariate Gaussian models of these feature vectors using Kullback-Leibler divergence. It is confirmed that all three methods are suitable to solve an open set problem in large 3D datasets (more than 1000 different geometries). Classification and training are image-based using different multi-view representations of the geometries.

Published: September 2022

Evaluation of the effectiveness of bone metastasis therapy is an urgent problem for patients with prostate cancer, mainly due to the relationship between bone metastases, survival and quality of life, which directly depends on the correct interpretation of the results of treatment response. It is known that some patients may experience a multidirectional therapeutic effect in the form of a positive response of some bone metastases and the progression of others. In addition, there are now many new therapeutics with different action profiles and often extremely expensive, so it is important to quickly recognize whether true or pseudo-disease progression is occurring, and this is more evident in patients enrolled in clinical trials with fixed protocols, often requiring radiographic assessment early after the start of treatment. Therefore, the use of additional imaging modalities in clinical practice along with PSA assessment may help improve early prediction of outcome and monitor response to therapy in patients with metastatic CRPC, optimizing the use of this costly treatment.

Introduction: Cervical lymph node metastases from papillary thyroid cancer were classified into three categories according to ultrasound: 1) Metastases were not visible on ultrasound; 2) Metastases met initial criteria for the diagnosis; 3) Metastases met typical criteria for the diagnosis.

   Purpose: To develop initial ultrasound criteria for the diagnosis of cervical lymph node metastases from papillary thyroid cancer.   Material and methods: We studied three groups of cervical lymph nodes in patients with papillary thyroid cancer. The first group consisted of 4307 lymph nodes that were not visible on ultrasound. However, in some of them histology revealed a metastasis. The second lymph node group consisted of 242 metastases, and the third one comprised 17 metastases causing first signs. Ultrasound imaging was performed by use of standard ultrasound machines that are widely used in clinical practice. The presence of metastases in the three groups was confirmed by histology and cytology.   Results: According to histological data, metastases were present in 961 (22.3 %) of 4307 cervical lymph nodes of level VI located in the fatty tissue and removed for disease prevention. These lymph nodes were missed on ultrasound, so that metastases remained undetected. Typical criteria for the diagnosis of metastases were: an additional space-occupying lesion in the fatty tissue of the neck, local fat deformation, depth/width ratio over 0.5, no differentiation between the cortical and cerebral layers, predominance of the tissue nature, avascularity, calcifications. Cervical lymph nodes with extranodal extension showed some changes in the shape and outlines, metastatic spread to the adjacent fatty tissue, muscles and vessels. Initial sonographic features that helped to identify a metastasis included microcalcifications and an additional nodal space-occupying lesion occupying a part of the cortical and cerebral layers and being seen as the hyperechoic tissue or a cavity with fluid, or as a mixture of the hyperechoic tissue with fluid. The space-occupying lesion was round or ovoid in shape. There was no extranodal extension of early metastases. The space-occupying lesion was 0.5–0.7 cm in size.   Conclusion: Ultrasound can detect metastases that cause first signs. Besides, it helps guide biopsies.

Published: September 2022

The features of the interpretation and practical use of more than 100 radiological terms are considered. It is shown that in all three areas of medical radiology (radiation diagnostics, nuclear medicine and radiation therapy) there are a number of terms that do not meet the requirements that apply to scientific terminological systems. These terms do not meet the criteria of unambiguity, adequacy to the terminating concept, consistency, brevity and compliance with the norms of the Russian literary language, especially when directly copying the corresponding English terms. At the same time, it is important to ensure the correct and unambiguous interpretation of terms not only by professionals in the field of medical radiology, but also by specialists in related fields of knowledge. A brief glossary of radiological terms that are difficult to unambiguously understand is presented, which contains some of the most commonly used erroneous terms in this field, explanations of the relevant concepts and correct, according to the authors, terminological solutions.

El objetivo de esta investigación fue evaluar la fertilidad del suelo a través de los parámetros físicos y químicos considerados como indicadores de la calidad del suelo; de sistemas de producción (SP) combinados con maíz-Inga vera (M-I) y maíz-Canavalia ensiformis (M-C), comparados con dos ecosistemas naturales de la región: bosque de pino-encino (BOS) y selva baja caducifolia (SEL). Se consideró la clase textural y se cuantificaron los siguientes parámetros: capacidad de campo, punto de marchitez permanente, pH, materia orgánica, fósforo, potasio, calcio, magnesio, hierro, manganeso, aluminio y capacidad de intercambio catiónico. De acuerdo con los resultados, no se encontraron diferencias significativas entre los SP y los ecosistemas naturales para ninguna de las propiedades del suelo; por lo que se puede deducir que los SP pueden llegar a mantener las condiciones físicas y químicas del suelo de manera similar a un ecosistema de vegetación natural al haber utilizado especies de leguminosas.

El cambio climático se concibe como una de las principales preocupaciones del contexto actual para organizaciones internacionales como el Programa de las Naciones Unidas para el Medio Ambiente (PNUMA) y el Grupo Intergubernamental de Expertos sobre el Cambio Climático (IPCC). También los diferentes Estados han tomado en cuenta los riesgos de este fenómeno. Por ejemplo, Costa Rica firmó un pacto Nacional por los Objetivos de Desarrollo Sostenible (setiembre, 2016), que incluye la Acción Climática como un tema prioritario. Por lo tanto, para abordarlo, como resultado de la experiencia docente en la universidad, se considera que para la formación en este tema, no se trata solamente de transmitir conocimientos y técnicas de investigación; sino que todo esto debe complementarse desde perspectivas humanísticas, sociales y ciudadanas que procuren despertar el espíritu crítico del estudiantado, reforzando y ampliando su formación integral y promoviendo la práctica de valores éticos y morales, desde lo personal, lo profesional y lo comunitario, como parte de la misión de la Educación Superior.
 
En este trabajo se presenta tres casos de estudio dados en la Universidad Nacional, Costa Rica. El primero aborda la experiencia del Curso “Perspectiva Humanística del Cambio Climático” del Centro de Estudios Generales, que se imparte para estudiantes de primer ingreso de todas las carreras. El segundo trata sobre los trabajos finales de graduación de la Carrera de Administración, específicamente en los cursos de Trabajo de Investigación I y Trabajo de Investigación II, y el tercero, consiste en la experiencia de la Red de Amigas y Amigos del Río Pirro como una articulación entre la academia y la comunidad mediante herramientas de Ciencia Abierta, Difusión de la Ciencia y Ciencia Ciudadana. 
Palabras clave: cambio climático, humanismo, investigación participativa, pensamiento crítico, educación superior, ciencia ciudadana.
Liderazgo y Empoderamiento de la Mujer para el Desarrollo Económico y Social En el departamento de Jalapa
Authors: Hernández Lemus Sulma Maritza
Published: September 2022

La presente investigación tiene como objetivo evaluar la percepción que tienen las docentes y estudiantes de la universidad de San Carlos de Guatemala del departamento de Jalapa del Centro Universitario de Sur Oriente, Sobre Liderazgo y Empoderamiento de la mujer para el Desarrollo Económico y Social. Para el efecto se realizó un cuestionario utilizando las variables que permitieron dar respuesta al estudio y así analizar las circunstancias que favorecen o impiden el acceso de mujeres a cargos directivos de alta gerencia, en torno a las barreras de empoderamiento o estereotipos que ayuden a implementar un liderazgo transformacional, en lugar de imitar un liderazgo masculinizado.   Se realizó una búsqueda electrónica de más 40 publicaciones científicas para fundamentar la teoría.
Se ha alcanzado importante posicionamiento  pero todavía falta mucha brecha, así mismo acotar el camino hacia la igualdad, invertir en actividades programas y proyectos para el desarrollo económico tomando en consideración que las mujeres son agentes claves para la economía de sus familias, si se quiere un futuro sustentable en miras de una sociedad con un desarrollo sostenible, se debe involucrar  al gobierno, sociedad civil y empresas por medio de alianzas estratégicas en apoyo a las mujeres para su liderazgo , empoderamiento y emprendimiento.
Palabras clave     Liderazgo, Empoderamiento Mujer, Desarrollo económico y Social.
Diferencias sustanciales entre empleo, subempleo y desempleo en los jóvenes de américa latina.
Authors: PALMA CARTAGENA DANY FRANCISCO
Published: September 2022

Los jóvenes enfrentan obstáculos individuales en inserción laboral, existen muchos indicadores como el desempleo y el subempleo, adherido a ello el uso de la tecnología en el tema del empleo no ha venido a favorecer tanto a la juventud, en sí ha venido a reemplazar el trabajo de muchos y es por ello por lo que la juventud atraviesa carencia de empleo, sumado a esto muchas instituciones están apostándole al telemercado, situación que afecta el empleo de muchos jóvenes en América Latina. De los jóvenes un buen porcentaje más alto son mujeres a las que afecta el tema del desempleo debido a grandes dificultades históricas sexistas y patriarcales que se oponen a que las mujeres se inserten en el campo laboral.
Otro punto es analizar las diferencias existenciales entre empleo formal e informal, así como el desempleo y subempleo en algunos países de América Latina tales como Ecuador, Perú, México, Argentina, Guatemala haciendo especial énfasis en la juventud.

Protecting all people from the harmful effects of environmental exposures relies on the coordinated efforts of scientific researchers, regulatory agencies, legislators, and the public. Environmental justice addresses the disproportionate impact that harmful environmental exposures have on individuals and communities who are minoritized and marginalized. It has long been known that environmental problems disproportionately impact these groups; however, addressing these problems has been impeded by structural racism and other biases. Developing effective interventions to eliminate these disparities requires a more diverse and inclusive modern workforce produced by a bottom-up approach beginning with education and professional development of the next generation of researchers. The most effective approaches to addressing inequities rely on active input from impacted populations to ensure cultural and social acceptance and adoption of interventions. Credibly pursuing these efforts in a sustainable, inclusive manner will require a concerted shift in workforce demography. One potential strategy to address these workforce disparities features academic-industry partnerships with targeted professional development programs aimed at minoritized and underserved populations.
