Objective assessment of the speech quality broadcasted by local Digital Radio in selected locations in Wroclaw
Authors: Brachmański Stefan , Kin Maurycy , Rurzyńska Natalia
Published: July 2024

The development of digital radio, observed in recent years, and the advantages offered by this medium are resulting in the expansion of the audience. In order to ensure the proper quality of broadcasting, it is necessary to monitor this quality. The assessment based on listening tests is very expensive and organizationally inconvenient. The development of methods for objective evaluation of signals makes it possible to monitor the quality of transmitted content, without the need for troublesome procedures associated with subjective evaluation. The good correlation of subjective evaluation and objective measurements in the transmission of perceptually encoded signals, reported in the literature, may allow for random quality monitoring. The authors decided to test the feasibility of using two objective evaluation methods to assess the quality of the speech signal transmitted on digital radio by comparing the results obtained with the subjective evaluation. The paper presents the results of objective measurements of speech quality transmitted via Digital Audio Broadcasting+ in Wroclaw agglomeration. Measurements have been done in various city sites in order to determine the influence of the location on speech quality. The obtained results of the assessment performed by the use of two methods of testing: PESQ and POLQA, allowed to find a correlation between the objective and subjective results of quality evaluations. The method of objective testing may be used for monitoring the quality of signals in Digital Audio Broadcasting networks especially spoken broadcasts.

A new efficient predictor blending lossless image coder
Authors: Ulacha Grzegorz , Stasinski Ryszard
Published: July 2024

In the paper a highly efficient algorithm for lossless image coding is described. The algorithm is a predictor blending one, a sample estimate is computed as a weighted sum of estimates given by subpredictors, here 27 ones, hence the name Blend-27. Data compaction performance of Blend-27 is compared to that of numerous other lossless image coding algorithms, including the best currently existing ones. The compared methods are ”classical” ones, as well as those based on Artificial Neural Networks. Performance of Blend-27 as a near-lossless coder is also evaluated. Its computational complexity is lower than that of majority of its direct competitors. The new algorithm appears to be currently the most efficient technique for lossless coding of natural images.

Sinonasal angiosarcoma: case report and literature review
Authors: Milea Andreea , Milea Alex , Sarafoleanu Codrut
Published: July 2024

BACKGROUND. Angiosarcoma is a neoplastic tumor that originates from endothelial cells, accounting for less than 2% of all sarcomas. The sinonasal localization of angiosarcoma is uncommon. It is a highly aggressive tumor with an increased risk of local recurrence.

CASE REPORT. We present the case of a 24-year-old male patient with 1 month of left side epistaxis, left nasal obstruction, headache and left hemifacial paresthesia. The CT scan of the skull and paranasal sinuses performed with intravenous contrast showed a macronodular heterogenous tissue lesion, partially hyperdense spontaneously, iodophilic, with multiple vascular trajectories apparently of the arterial type, localised in the left maxillary sinus and ipsilateral nasal cavity. The first result from histopathological examination concluded for sinonasal angiofibroma with no signs of malignancy. Even if a wide resection was performed by external and endoscopic approach, a quite quick local recurrence appeared. After the second surgical resection of the tumor, the histopathological examination correlated with immunohistochemical tests and the clinical-imaging aspect concluded on sinonasal angiosarcoma. The proper treatment was delayed because of the histopathological examination misinterpretation.

CONCLUSION. A thorough histopathological examination and immunohistochemistry have an important role for an adequate diagnosis of sinonasal angiosarcoma.
HERMENÊUTICA DO DIREITO DAS COISAS
Authors: BRETAS HUGO RIOS
Published: July 2024

A história dos direitos reais é complexa, na medida em que a compreensão da função social passa pela minimização do caráter absoluto da propriedade privada. Por isso, atingir o estágio privatista funcionalizado exige profunda evolução existencial, o que se dá em tempos constitucionais mais contemporâneos. Diante disso, até os dias atuais, ainda se vive um movimento incipiente de compreensão deste princípio. A função social é umbilicalmente interligada. A função social é umbilicalmente interligada à propriedade privada, motivo pelo qual a essência da propriedade só há de se consolidar caso não existam vilipêndios ao princípio da função social. A teoria do patrimônio mínimo nos transmite que a propriedade e a posse não são os seus principais componentes e sim a dignidade, em conjunto com as suas irradiações. Há um autêntico encontro hermenêutico entre a dignidade da pessoa humana, o processo de repersonalização, a função social e o patrimônio mínimo. Trata-se de um interdependente bloco interpretativo.
O QUE HÁ DE SINGULARMENTE PROBLEMÁTICO NA INJUSTIÇA EPISTÊMICA POR EXCESSO DE CREDIBILIDADE AO TESTEMUNHO DO ESPECIALISTA?
Authors: Rocha Michael GUEDES
Published: July 2024

O testemunho de especialistas é objeto de expressiva atenção pelos estudiosos da prova em virtude de suas notáveis particularidades em comparação com as demais formas de testemunho. Esse artigo dedica-se a apresentar os reflexos dessas particularidades em contextos em que esse testemunho recebe credibilidade excessiva, configurando uma injustiça epistêmica. Para isso, em primeiro, são feitas considerações que explicam o porquê da adequação de categorizar o excesso de credibilidade como um caso de injustiça epistêmica. Em segundo, aborda-se o que há de singularmente problemático nesse cenário. Em terceiro, as consequências práticas dessa singularidade são analisadas a partir de um caso real de prisão de inocente (Daniele Toledo). Por fim, observações são feitas sobre o que se identifica como apropriado para avançar na contenção dessa forma ímpar de injustiça epistêmica.

Published: July 2024

Este artigo ensaísta se propõe a abordar a hermenêutica e o metaverso com o propósito de estabelecer interrelações entre um e outro, assim como possíveis implicações que podem advir dessas relações para as ciências jurídicas. A hermenêutica não se restringe à atividade de interpretação de textos escritos e contempla, de forma mais abrangente, orientações epistemológicas de compreensão da realidade. Esta, por sua vez, em razão do acelerado desenvolvimento tecnológico, avança em direção a ambientes exclusivamente digitais que, em conjunto, constituem o que se conhece como metaverso. Enquanto instrumento de compreensão da realidade, a hermenêutica pode ser empregada como ferramenta e base epistemológica para entendimento das nuances e caracteres do novo e crescente universo digital. As ciências jurídicas não estão alheias ao processo de informatização e digitalização do cotidiano e são impactadas, tanto em aspectos teóricos quanto práticos, pelas constantes transformações trazidas pelo desenvolvimento tecnológico, exigindo assimilações e ressignificações de conceitos jurídicos.

Published: July 2024

This article analyzes the diversity of approaches to the organization of activities of state regulators in the field of gambling and lotteries in European countries, their common features and differences, advantages and shortcomings. Given the uniqueness of approaches to the organization of state regulation in the field of gambling and lotteries, the similarity of some conditions and principles, as well as the prospects of use in Ukraine, special attention is paid to the relevant experience of Belgium, the Netherlands, Germany, the United Kingdom, France, Switzerland and others. It has been established that the European experience of organizing the activities of the state regulator in the field of gambling and lotteries reveals significant differences in approaches to state regulation in the field of gambling business regarding legal bases, subordination, accountability, the order of formation and composition of the state regulator, the scope of its powers, etc. Despite such differences, state regulation in the field of gambling business is usually entrusted to a separate collegial state body endowed with broad regulatory, licensing, control and other powers. Conclusions are made about the expediency of applying relevant European experience in the context of improving the legal regulation of the Commission for Regulation of Gambling and Lotteries in Ukraine.

Reproducción y procreación: Marcos categoriales para una teoría crítica desde Latinoamérica
Authors: Soazo Christian Andrés
Published: July 2024

El presente trabajo se sitúa desde los diversos horizontes históricos que convergen en la crisis civilizatoria contemporánea, proponiendo las categorías críticas de reproducción y procreación, derivadas de una lectura hermenéutica, teórica y política inédita del pensamiento Marx, llevadas a cabo por Frank Hinkelammert y Jorge Veraza respectivamente. A partir de la confluencia de sus presupuestos teóricos, asentados en una rigurosa y profunda interpretación económico-política y filosófica, se reflexiona en primer lugar sobre la problemática del valor de uso y la producción de valores de uso nocivos, para la perpetuación de una lógica anti-utópica (conservadora) o “mística del ocaso” propia del fundamentalismo apocalíptico del mercado. Se indaga finalmente en los criterios materiales y normativos esenciales para concebir una ciencia crítica  (o teoría crítica) arraigada sobre la racionalidad reproductiva y las fuerzas productivas procreativas, con el fin de trascender el encapsulamiento tautológico y anestésico de las ciencias empíricas modernas, especialmente en el campo de las ciencias sociales y humanidades, fundamentadas desde el pensamiento de Weber.
Franz Hinkelammert y la cuestión del desarrollo
Authors: Albornoz Adolfo
Published: July 2024

El año 2023, en Costa Rica, a los noventa y dos años, murió Franz Hinkelammert, economista, filósofo y teólogo de origen alemán. Para su vasta trayectoria intelectual fue decisiva la primera década que vivió en América Latina, específicamente en Chile, entre 1963 y 1973, país del que debió salir tras el Golpe de Estado. En Santiago, Hinkelammert se relacionó con discursos y prácticas del Desarrollismo Cepalino, intervino en debates y proyectos que impulsaron la Teoría de la Dependencia y participó en diálogos y acciones que animaron la Teología de la Liberación. Estas experiencias teóricas y políticas lo acompañaron durante más de medio siglo de trabajo intelectual a partir de la especificidad latinoamericana. Este artículo, enfocado en la cuestión del desarrollo, propone una breve reconstrucción sociohistórica del campo intelectual sesentista chileno y latinoamericano donde Hinkelammert activamente participó, entrecruzada con material testimonial proveniente de entrevistas inéditas con el célebre pensador. El objetivo es situar su trascendente obra en el canon de la crítica latinoamericana de la modernidad, conectando la labor temprana de Hinkelammert con corrientes actuales del pensamiento crítico latinoamericano.

The Impact of Traditional Health Practices, Revivalism, Patriarchy and Economic Factors on the History of the Baptist Convention’s Health Response in Post-Independence Malawi
Authors: Fiedler Rachel NyaGondwe , Landman Christina
Published: July 2024

This article reports on a study that sought to investigate the impact of traditional health practices, revivalism, patriarchy and economic factors on the history of the Baptist Convention’s health responses during the past 50 years of its existence in the South East Region of Malawi. During this period, Christians in Malawi continued to rely on traditional health practices, faith healing and biomedical medicine. Traditional healing practices were part of their culture and promoted by the patriarchy as some pastors of the church were also chiefs. Access to biomedical approaches became a challenge because of economic factors. Faith healing practices took a different form under the influence of revivalist movements. There are several studies on healing practices based on mainline churches in Malawi, however, there is a lack of similar studies on the Baptist Convention. The aim of the study was to investigate the impact of traditional health practices and economic factors on the history of the Baptist Convention’s health responses in the South East Region of Malawi in the Post-Independence Era (post 1966). Based on qualitative ethnographic research, especially of participant observation since 2000, the study found that the Baptist Convention’s health responses were always wholistic and influenced by the Baptist distinctive of individual conscience, patriarchy, economic factors and church polity. The Baptist distinctive is the total of several precious beliefs and practices based on the Bible.
Spurring Copyright Rights Holders’ Innovation in the Digital Age Through a Statutory Remuneration Copyright Levy for Private Home Copying
Authors: Hungwe Brian
Published: July 2024

The United Nations estimates that in the next few years the creative industry will constitute around 10% of global gross domestic product. The sector has shown a sharp spike of growth at 12% per annum, particularly in the developing world. In South Africa, copyright holders—particularly youths—involved in creative digital expressions are now victims of rampant digital copying of their works without compensation. South African legislators have been warned that without a private copying levy system, the introduction of private copying exceptions such as fair use under the current Copyright Amendment Bill of 2017 will have adverse economic effects on creators. The current copyright bill does not have a provision for a copyright levy despite carrying a private copying exception. The futility of copyright law enforcement in private homes lies in part with the constitutional right to privacy protection enshrined in the Bill of Rights and the administrative impracticalities around prosecuting millions of copyright infringers. This article’s finding is that private copying is inevitable and harms copyright holders’ remuneration. As such, the rejoinder to normalised deviant copying behaviour is a private copying levy.
Technical and Vocational Education and Training (TVET) and Life Skills for Resilience-building among Female Youths in Chiredzi and Mwenezi, Zimbabwe
Authors: Muchabaiwa Chipo , Chiweshe Manase Kudzai , Mapara Jacob
Published: July 2024

This article examines the role of technical, vocational education and training (TVET) and life skills interventions in strengthening resilience and expanding opportunities for vulnerable female youths in the marginalised districts of Chiredzi and Mwenezi, Zimbabwe. Mixed-methods research evaluated 306 young women aged 18–35 who participated in such programmes, assessing impacts on livelihoods, agency and gender dynamics. Findings revealed multifaceted vulnerabilities, including economic hardship from poverty, income insecurity, infrastructural gaps limiting health and education access, and gender constraints. Climate shocks like droughts exacerbated adversities, driving risky coping strategies. While biases limited overall TVET enrolment for females, many accessed feminised trades like garment-making. Though domestic roles occasionally disrupted attendance, women overwhelmingly reported positive impacts on developing livelihood skills and self-confidence. However, translating gains into sustainable enterprises remained challenging amid personal, programmatic and societal barriers, including mobility constraints, lack of post-training support, and norms prioritising marriage over careers. The analysis emphasises holistic women-centred interventions, combining skills training with gender-transformative components like male engagement to enable success. Recommendations involve strengthening recruitment, curricula relevance, accommodative implementation, sustained post-graduate assistance, and harnessing graduates as inspirational agents of change able to overcome restrictive norms and unlock young women’s economic empowerment potential in the long term.

Professional boundaries are a set of guidelines, expectations and rules that set the ethical and technical standards between the child and youth care workers (CYCWs) and young people. Professional boundaries are important to establish and maintain, as they assist to build the therapeutic relationship between the professional worker and client. Therefore, this study aimed to explore the perspectives of CYCWs in relation to professional boundaries in residential child and youth care centres (CYCCs) in Durban, KwaZulu-Natal, South Africa. To achieve this aim, the study was guided by a qualitative, exploratory, and descriptive design. A purposive sampling technique was employed, and semi-structured interviews were used to collect data from 14 CYCWs. The analysis suggests that, while CYCCs have developed professional boundaries, there remains a great need for the provision of clear rules and regulations about professional boundaries, and life-long training (in-service professional development) focused on boundaries and support from management.

Published: July 2024

The colonial nature in which academia has taken shape has meant that its practices of acquiring and producing knowledge are often violent towards those affected by sexual and gender-based violence. Shifting the praxis of how knowledge is understood and engaged in, means critiquing these traditionally colonial methods, as well as identifying new ways of engaging with academia and the framework of conducting research. Contributors of the Unsettling Knowledge Production on Gendered and Sexual Violence Project have undertaken this idea in their individual and collaborative work as a way to challenge, disrupt and change the sometimes violent nature of research on sexual and gender-based violence. These contributors believe that there is a responsibility for producing knowledge that is respectful and which contributes towards the goals of care, ethical engagement and social justice, from the inception of the research work through to its dissemination. In this article, we look at their reflections on what unsettling knowledge means for them as they simultaneously navigate and resist colonial structures within which their work still takes place. They describe their journeys within this unsettling and decolonial framing and how they try to enact it in their work on sexual and gender-based violence.

Published: July 2024

Background Problems: There has not been much research on how exercise strategies affect muscle soreness and activation patterns. Research Objectives: This study examines the acute effects of rope-based functional training on muscle group pain response in student athletes at the Faculty of Sport Science, Universitas Negeri Medan tennis court. Methods: An experimental method and a pre-post-test time series design were used for analysis. Seven samples were selected using purposive sampling. All participants engaged in a warm-up, a central phase of rope training with a maximum of three sets per exercise, ten hand swing repetitions, a one-minute break between sets, and a cooling phase. Three 100-mm VAS and painometer data collection sessions were conducted. At a 0.05 significance level, the research data was examined using one-way ANOVA for normal data and Friedman for aberrant data. Both studies used SPSS 16.0. Findings and Results: The trial demonstrated that rope training induces soreness in all working muscles. However, no muscle group exhibited discomfort above 50 mm. Conclusion: In order to optimally activate muscles, determine exercise doses and blood lactate levels in relation to muscle discomfort, it is necessary to understand how battle rope training reduces muscular soreness and improves muscle activation in student-athletes on the tennis court. This understanding can inform the development of personalised training programmes and injury prevention techniques.

По итогам проведённой аналитической оценки рабочих органов малогабаритных машин для обработки почвы, в частности в процессе исследования мотоблоков, получены результаты, которые свидетельствуют о наличии ряда недостатков. Рабочие органы сконструированы таким образом, что отмечается необоснованная ширина захвата; агрегаты не обеспечивают надлежащее качество рыхления и целостность верхнего слоя почвы; рабочие органы не удовлетворяют принципу универсальности действия и унификации. В ходе работы агрегата рыхлительные лапы не в состоянии обеспечить равномерное крошение почвы на всю глубину, на которой производится обработка. При обработке земельных участков с помощью агрегатов происходит формирование большого количества глыб и развальных борозд. Не производится профилактика роста сорных растений, так как в ходе обработки почвы сорные растения подрезаются рабочими органами агрегата, но не удаляются из верхних слоев почвы, в результате чего прорастают вновь. Мы провели исследования, по результатам которых предлагаем использовать для обработки почвы универсальный каток, функциональные возможности которого позволяют качественно прорыхлить верхний слой обработанной почвы при одновременном удалении сорных растений на поверхность земли и последующем их прикатывании катком. В рамках настоящей работы представляем методику, которая может использоваться в целях определения колебаний катка, предлагаемого к внедрению.

Based on the analytical assessment of the working elements in small-sized machines for soil cultivation, particularly, research into walk-behind tractors, the research results revealed a number of disadvantages. First, the working elements are designed to feature unreasonable working width; aggregates are not able to provide the proper quality of loosening and integrity of the upper layer; working elements are not able to satisfy the principle of universality of action and unification. During the operation of the unit, the cultivating paws are not able to ensure uniform crumbling of the soil to the entire depth at which the treatment is carried out. During the processing of land using aggregates, a large number of blocks and breakup grooves are formed. And also, weed growth is not prevented, since during soil treatment, weeds are cut by the working elements of the aggregate, but are not removed from the upper layers of the soil, as a result of which they germinate again. Based on the obtained research results we propose using a universal roller for tillage, the functionality of which allows to qualitatively loosen the top layer of cultivated soil, while removing weeds to the earth surface and roll them up. In the framework of this research, the authors propose the method that can be used to determine the vibrations of the roller.

Published: July 2024

На рынке стеклокристаллических строительных материалов пеностекло является одним из перспективных. Для достижения оптимальных физико-технических параметров пеностекла требуется разработка технологии, которая позволит регулировать процессы термической обработки сырьевой смеси для получения пеностекла, не снижая его эксплуатационных характеристик. В технологии пеностекла важным этапом является стадия вспенивания. При вспенивании происходит изменение температуры сырьевой смеси от приповерхностных слоев к центру засыпки, аналогично протекает реакция термического разложения газообразователя, что может повлечь за собой неравномерную поризацию материала. Математическая модель, представленная в работе, позволяет моделировать распределение температурных полей на границах контакта металлической формы для вспенивания и сырьевой смеси для производства пеностекла, а также прогнозировать дальнейшую динамику температуры в сырьевой смеси, что является ключевым фактором при формировании равномерной поризации конечного продукта.

On the market of glass-ceramic building materials, foam glass is one of the most promising ones. In order to achieve the optimal physical and technical parameters of foamed glass, it is necessary to develop the technology that would allow regulating the processes of heat treatment of the raw mix to obtain foamed glass, without reducing its performance characteristics. In foamed glass technology, an important parameter is the foaming process. During foaming, the temperature of the raw material mixture changes from the surface layers to the center of the backfill, the activation of the thermal decomposition of the gas-forming agent proceeds in a similar way, which may entail uneven porisation of the material. The mathematical model presented in this paper allows to model the distribution of temperature fields at the contact boundaries of a metal mold for foaming and a raw material mixture for producing foam glass and to predict the further course of temperature change in the raw material mixture, which is a key factor in the formation of a uniformly porous final product.

Использование оснований и фундаментов повышенной несущей способности является актуальной задачей современного геотехнического строительства. Из всех существующих технологий возведения таких фундаментов наиболее востребованными являются заглубленные конструкции как, например, буровые сваи больших диаметров. Существующие технологии устройства этих свай позволяют достичь значительных значений несущей способности Fd. При этом ее увеличения возможно добиться только за счет изменения их длины и диаметра. Альтернативой буронабивным сваям для целей достижения высоких значений Fd являются буроинъекционные сваи, изготавливаемые по электроразрядным технологиям – сваи ЭРТ. С помощью уширений, устроенных вдоль ствола сваи ЭРТ, создается возможность увеличения их несущей способности. При этом каждое дополнительное уширение существенно увеличивает Fd. Таким образом, регулируя количество уширений в зависимости от напластований инженерно-геологических элементов строительной площадки, можно создать возможность достижения требуемых значений несущей способности свай ЭРТ.

The research into the use of foundations with high bearing capacity is the relevant and actual problem of modern geotechnical construction. The structures in demand are mainly underground structures, such as piles of large diameters. The existing technologies used for the construction of these piles make it possible to achieve high bearing capacity Fd. At the same time, this increase can be achieved only by changing their length and diameter. An alternative to bored piles for achieving high Fd values are drilling-injection piles manufactured using electric-discharge technologies – EDT piles. With the help of broadening arranged along the barrel of and EDT pile, it is possible to increase their bearing capacity. Moreover, each additional broadening substantially increases the value of Fd. Generally, by means of regulating the number of broadenings, depending on the layering of the engineeringgeological elements of the construction site, it is possible to achieve the required values of the bearing capacity of EDT piles.

A new class of chiral N-Heterocyclic Carbenes derived from pyridine, namely N-hydroxyalkyl pyrid-2-ylidenes, was developed. Capitalizing the exceptional steric and electronic features of pyrid-2-ylidene core with the presence of the chiral hydroxyalkyl-chelating arm on the nitrogen-atom, these ligands demonstrated high performances in copper-catalyzed asymmetric allylic alkylation of dialkylzincs to various allylic or dienic phosphates with excellent gamma-selectivity (>98%) and enantioselectivity (up to 95% ee). Importantly, the catalyst loading can be decreased below to 0.5 mol% without any loss of catalyst efficiency, thus outperforming N-hydroxyalkyl imidazoline-2-ylidene congeners. Moreover, thanks to the versatile post-transformation of resulting enantioenriched skipped 1,4-dienes, various relevant building blocks were synthesized, notably a key intermediate in the total synthesis of (+) Phorbasin C. Furthermore, by involving a transient oxazolidine, which acts as a masked carbene before the insertion of the metal center, a well-defined but air-sensitive N-hydroxyalkyl pyrid-2-ylidene copper(I) chloride complex was isolated. Deuteration experiments and computational studies provided valuable insights about the formation of the oxazolidine and the corresponding copper complex.

This communication extends on findings previously reported in which students were asked to construct Reaction Coordinate Diagrams (RCDs) de novo. Instead of asking students to construct RCDs, this study explores students’ understanding of kinetics and thermodynamics when provided with mechanisms for the Aldol and Claisen condensations with a specific focus on the key steps in the mechanisms. The findings include data from a cohort that received specific lecture content on kinetics and thermodynamics on these specific mechanisms compared to a cohort that did not receive specific instructions. The findings show that students associate kinetics and thermodynamics interchangeably by identifying the rate-determining step as associated with the less stable intermediate even after receiving specific instruction. The data associated with this particular analysis suggest that explicit instruction of this single reaction is not sufficient for proper analysis of the reactions. The notion that specific reactions can be memorized, thus, is invalid as it relates to these reactions. A more holistic understanding of kinetics and thermodynamics seems to be required for students to demonstrate a deep understanding of this specific reaction.

Québec has experienced historical damaging earthquakes in several seismic zones (e.g. 1732 M5.8 Montréal, 1663 M7 Charlevoix, 1935 M6.2 Témiscamingue). Despite a high seismicity rate, no surface-rupturing faults have been discovered due to a combination of dense vegetation cover, recent glaciation, sparse earthquake records, and low regional strain rates. We manually searched lidar-derived digital elevation models (DEMs) of the region to search for potential post-glacial surface-rupturing faults across southern Québec and identified a scarp $\sim$50km north of Montréal. We performed three geophysical surveys (ground penetrating radar, depth estimates from ambient seismic noise, and refraction seismology) that revealed a buried scarp, confirmed with a <1 m-deep hand-dug test pit. These observations convinced us to excavate the first paleoseismic trench in Québec to test for the presence of a surface-rupturing fault in July 2023. We found a glacial diamict containing no signs of syn- or post-glacial deformation. In this paper, we present the observations that led to the identification of a scarp and hypothesized faulting. We highlight the importance of trenching to confirm recent fault scarps in challenging environments. We hope our study can be used to optimize future paleoseismic research in the province of Québec and similar intracratonic glaciated landscapes.

Distributed computing is quickly developing and a lot more cloud suppliers are arising. Cost effectiveness and asset cost boost become two main pressing issues of cloud suppliers to stay serious while creating gain. The benefit boost issue in unified cloud conditions collaborate to build the level of multiplexing has been explored. Frame novel financial matters enlivened asset designation components to handle the benefit expansion issue according to the point of view of a cloud supplier acting exclusively. Confirmation control components custom-made inside a Benefit the board system to expand asset cost has been proposed. Existing deliberations for in-memory capacity on bunches, for example, conveyed shared memory, key value stores, data sets, and Piccolo, offer a connection point in view of fine-grained updates to changeable state (e.g., cells in a table). Foreseeing the heap of its cluster is tweaked. The last heap of the entire network is acquired by adding the heaps of each bunch. The proposed strategy for load anticipating in Savvy Lattice enjoys two significant benefits. 1) Learning client ways of behaving further develops the expectation exactness as well as has a low computational expense. 2) sCCRF can actually display the heap anticipating issue of one client, and at the same time select key highlights to distinguish its energy utilization design. With this point of interaction, the main ways of giving adaptation to non-critical failure are to imitate the information across machines or to log refreshes across machines. Where different evaluating plans in numerous commercial centres are upheld by the supplier a sale based unique valuing component reasonable for selling the extra limit of the information centre acknowledgment of the proposed dynamic estimating system inside an evaluating as a help structure. Practical asset distribution in view of following methodologies are Cost Effectiveness of the Cloud: Cost decreases and benefit builds, Pay-more only as costs arise evaluating, Ramifications of multi tenure.   Planning and asset designation as an expense effective arrangement: Double-dealing of utilization qualities, Unequivocal thought of client experience/fulfilment.

Given the recent developments and advancements in the software engineering field, the internet-based entertainment network is one of the most important aspects of human existence. This environment has established itself as a popular forum for exchanging information and news on all topics as well as daily reports, which is the major period for information collecting and transmission. There are a variety of advantages to this environment, but from another angle, there are a lot of false data and information that lead readers and clients astray while they are looking for the information they need. One of the major problems with this approach is the lack of reliable data and true new insight regarding internet entertainment data. To combat this problem, we have created an integrated framework for various @block chain and normal language processing (NLP) components that applies AI techniques to recognize fake news and better anticipate fake client records and postings. This methodology uses the Support Learning approach. The decentralized block chain structure was used, which provides the framework of computerized contents authority verification, to work on this stage with regard to security. More specifically, the goal of this framework is to promote a secure environment for spotting and identifying fake news in online entertainment companie
