Manejo de residuos sólidos en entornos rurales. Estudio de caso: Mongua, Boyacá
Authors: Aguilar-Botia Karent-Dayana , Hernández-Botia Faber-Andrés , González-Santos Wilson
Published: July 2023

Se estima que el manejo de residuos sólidos a nivel global aún es insuficiente debido a factores como: el aumento en la generación, los hábitos de consumo, los sistemas de producción y la falta de alternativas para su aprovechamiento y/o tratamiento. A lo largo de este tiempo se han diseñado e implementado estrategias que buscan mitigar esta problemática, pero, estas son en su mayoría implementadas en las zonas urbanas, aunque la zona rural no es ajena a esta realidad. Por lo anterior, se realizó un estudio de caso del manejo actual que se da a los residuos sólidos en tres veredas del municipio de Mongua, correspondientes a Centro, Duce y Monguí. La información fue recolectada a través de encuestas, entrevistas semi-estructuradas y talleres participativos, contando con la participación de las integrantes de la Asociación Campesina Huerto Alto Andino. Al concluir el ejercicio se determinó que la quema de residuos sólidos en estufas de carbón o en fogatas, es la práctica más común en los hogares, así como el aprovechamiento de material orgánico para producir abono y ser usado en sus huertas y cultivos, en cuanto a lo reciclable se evidencia que son comercializados o algunos enterrados, práctica que afecta la salud, el ambiente y la economía del territorio. En este sentido, se concertaron compromisos de sensibilidad ambiental colectiva y, como mensaje a las autoridades municipales, se hace el llamado para contribuir en procesos de manejo adecuados e integrales de los residuos sólidos en zonas rurales que promuevan su desarrollo sostenible.
Participación en actividad física y deporte de la comunidad LGBT
Authors: Buitrago-Camacho Karen-Tatiana
Published: July 2023

El artículo aborda diferentes temáticas para poder entender, comprender y situar a la comunidad LGBTI en cuanto a la actividad física y el deporte, con base a los diferentes estudios que se analizaron tanto a nivel Nacional como internacional, en los últimos años. A partir de esta revisión se puede evidenciar que las perspectivas y significados de las personas en cuanto al tema o eje central de este artículo, pueden variar según diversos factores como: La edad, la profesión, el contexto, el sexo, el nivel deportivo, entre otros. Razón por la cual, mientras que algunas personas, tienen actitudes negativas y sesgos en relación con la diversidad sexual, también se evidencia en otros estudios un cambio positivo frente a las minorías sexuales LGBTI gracias al enriquecimiento teórico y el reconocimiento de esta comunidad, por instituciones sociales, políticas y culturales. Por otra parte, se puede concluir que hoy en día el ámbito deportivo sigue estando fuertemente arraigado por pensamientos heterosexistas que delimitan la participación de este colectivo, sin embargo, cabe destacar que ya se observa un cambio positivo por parte de diferentes organizaciones, materializado por el reconocimiento y aceptación de la participación de las personas LGBTI, en el contexto deportivo, como parte esencial de su libre desarrollo.
La dermatophilose des bovins à Dermatophilus congolensis dans les Antilles françaises. III. Comparaisons entre élevages infectés et indemnes
Authors: Matheron Gérard , Barré Nicolas , Roger François , Rogez B. , Martinez Dominique , Sheikboudou Christian
Published: July 2023

Une enquête destinée à déterminer les caractères distinctifs entre élevages atteints et élevages indemnes de dermatophilose a été menée dans 93 élevages bovins de Martinique et 120 élevages de Guadeloupe et Saint-Martin. Près de la moitié de ces élevages étaient ou avaient été infectés. La morbidité dans les exploitations concernées par la maladie est de 33 p. 100 en Martinique et de 29 p. 100 en Guadeloupe, les mortalités annuelles étant respectivement de 15 et 5 p. 100. On n'observe pas de différences de fréquence de la maladie en fonction de la saison et de la zone géographique. La présence de la tique Amblyomma variegatum, en revanche, est déterminante dans la situation de la Martinique où les animaux de toutes les races sont sensibles à la maladie. Dans ce cas, 63 p. 100 des élevages infestés sont atteints, contre 2,5 p. 100 pour les élevages encore épargnés par la tique. En Guadeloupe où le zébu Créole, du fait d'une sélection naturelle, est hautement résistant, seuls 27 p. 100 des élevages de l'enquête qui sont infestés connaissent la dermatophilose. Le détiquage régulier dans les deux îles a une action bénéfique sur la fréquence de la maladie. L'enquête révèle une typologie sous-jacente des élevages et permet de les classer en fonction de leur comportement face à la maladie.
L'oestrose des petits ruminants au Sénégal. Note préliminaire
Authors: Vassiliades Georges
Published: July 2023

Des observations faites aux abattoirs de Dakar de mars à décembre 1987 ont montré que 46,39 p. 100 des ovins et 57,89 p. 100 des caprins étaient porteurs de larves d'Oestrus ovis. Il existe une nette relation de cause à effet entre le jetage et la présence des larves matures qui, en raison de leur garniture d'épines, sont suffisamment irritantes pour provoquer l'inflammation des muqueuses nasales avec complications microbiennes possibles . Il est nécessaire de tenir compte de la fréquence et de la pathogénicité de l'oestrose dans l'étude étiologique des affections respiratoires des petits ruminants du Sénégal.
Observations sur les infestations par les strongles, durant la saison sèche, des pâturages à bovins inondés en permanence dans la région de Yom, État du Plateau, Nigeria
Authors: Onyali I.O.
Published: July 2023

Des échantillons d'herbes ont été récoltés dans les environs de 4 mares permanentes (2 très pâturées et 2 peu pâturées), situées dans la région de Vom. Les collectes ont eu lieu tous les 15 jours de novembre 1985 à avril 1986 et de novembre 1986 à avril 1987. Les larves ont été extraites par lavage et sédimentation et les décomptes effectués ont été exprimés en nombre de larves par kg de matière sèche. Parmi les larves de vers présentes dans les coprocultures, on distinguait Haemonchus, Cooperia et Oesophagostomum qui étaient les plus importants. Trichostrongylus, Bunostomum et Strongyloides étaient présents aussi, mais en très petit nombre. Les alentours des mares permanentes très peu pâturés étaient faiblement infestés, alors que ceux très pâturés se révélaient contaminés par de fortes infestations. Les pâturages fortement contaminés deviennent un milieu à risque de la moitié jusqu'à la fin de la saison sèche. Les traitements de routine durant la saison sèche sur les bovins qui ont accès aux pâturages, en particulier dans les zones fortement contaminées, sont dès lors nécessaires.
Résistance globulaire des hématies bovines
Authors: Quéval R. , Pagot E. , Sylla Souleymane , Maillard Jean-Charles
Published: July 2023

Une analyse de la résistance globulaire a été menée en exposant des globules rouges de zébus, taurins Baoulé et métis taurins x zébus à diverses concentrations salines. Les résultats statistiques n'ont montré aucune influence du sexe pour toutes les races. Chez les zébus, il y a une différence selon le type d'hémoglobine concerné. Ces derniers différent aussi des taurins et des métis. Le traitement des données a été réalisé en calculant la moyenne du pourcentage d'hémolyse pour tous les échantillons, ainsi qu'avec la concentration de NaCl correspondant à une hémolyse 50 p. 100. Ces différences peuvent donner une explication partielle de l'anémie dans les trypanosomoses bovines à Trypanosoma vivax ou T. congolense, moins prononcée chez les taurins Baoulé que chez les zébus.

Published: July 2023

Expandem-se pelo mundo as redes alternativas de alimentos, como grupos solidários de compras, mercados de agricultores e, particularmente, as Comunidades que Sustentam a Agricultura (CSA). Em uma CSA tradicional, os consumidores aderem a uma cota da CSA e concordam em pagar uma quantia que financie a produção agrícola e, em contrapartida, os agricultores entregam produtos, como hortaliças, frutas, entre outros, aos consumidores. Os riscos de produção são transferidos dos produtores para os membros da comunidade. O objetivo deste estudo foi caracterizar as CSAs no Distrito Federal, Brasil, e avaliar os impactos desses novos arranjos de produção e comercialização sob o ponto de vista dos agricultores e coagricultores. A coleta de dados foi realizada por meio de entrevistas, em amostra com 14 CSAs e 34 coagricultores, a partir de roteiro semiestruturado, composto por seis dimensões: Estrutura Organizacional; Cultura de Organização do Trabalho; Comunicação; Socioambiental; Logística; e Economia. Os resultados mais relevantes foram: para os agricultores − segurança, planejamento, estabilidade e independência financeira da atividade; adoção de métodos de agricultura orgânica; aumento da qualidade e diversidade do produto; melhoria na qualidade de vida; reconhecimento e valorização do trabalho rural; treinamento e adoção de práticas preservacionistas. Para os coagricultores − aumento da consciência socioambiental; preocupação com a saúde; conhecimento de novos produtos agrícolas e novos usos; redução de resíduos; empatia e racionalidade. Para a sociedade, esse novo arranjo de produção e distribuição de alimentos é positivo em diversos aspectos, principalmente devido ao aumento da conscientização ambiental, à diminuição do desperdício, à valorização da atividade rural e a uma maior autonomia financeira dos agricultores, o que pode auxiliar na redução da pobreza no campo.

Movimento histórico do direito à educação para as pessoas com deficiência: prescrições das Constituições brasileiras
Authors: Bigarella Nadia , Bassi Tânia Mara dos Santos
Published: July 2023

Este artigo tem como objetivo discutir o direito à educação como um direito social de todos as pessoas com deficiência, salvaguardado nas Constituições brasileiras e na legislação educacional como universal e um dever estatal, estabelecido por meio de políticas fundamentadas em valores democráticos: universalização da educação pública, gratuita e inclusiva, pilares da cidadania e do Estado Democrático de Direito. As  análises  documentais e bibliográficas envolveram a legislação educacional, as Constituições brasileiras e os estudos teóricos de Saviani (2013), Horta (1998), Cury (2014) e Vieira (2007), que discutem o conceito de educação como um processo inclusivo, democrático, sistematizado e constitutivo de um percurso formativo valorizado, o qual amplia as possibilidades sociais, reconhecidas e positivadas como direito à educação de todos. Para que se materialize tal direito para as pessoas com deficiência, exige-se mais do que prescrições impressas nos documentos do Estado brasileiro, exigem-se políticas que ampliem a defesa de uma sociedade baseada em valores humanos, universais e de respeito às liberdades. Também, requerem-se esforços, estratégias e recursos que levem à sua concretização e contemplem, de fato, as especificidades e necessidades de todos.

Authors: STOLYARCHUK Valentyna
Published: July 2023

Purpose – The paper aims to contribute to the knowledge of the problem-solution and the creation of a successful idea of the restaurant business development (in particular, through applying of the separation principles). Methodology/Design/Approach – A case study is conducted as a research strategy to test propositions expressing a necessary condition to investigate the possibility of applying the separation principles to solve a problem. The restaurant industry is defined as the area to which the theory is applied and from which cases are selected for testing. Findings – The application of separation principles as a methodological tool contributes to finding an effective solution to problems of the restaurant business development. Originality of the research – This paper represents the analysis of how some restaurateurs have overcome the COVID-pandemic problems. A model of the invention process is proposed, which helps practitioners to find an effective solution for the development of the restaurant business under crisis conditions and to implement the successful idea in time. The results of the study show the possibility of improving the created idea and its development. Two ways of implementing this process were identified: alternate application of the principles of separation and unification of different parameters.
The transition and formation of government after Lesotho’s 2022 elections
Authors: ‘Nyane Hoolo
Published: July 2023

Most assessments and analyses of Lesotho’s elections have focused on the post-election conflict. There has been little attention to the role of the Independent Electoral Commission (IEC) as the key player with the constitutional mandate to ensure credible, free, and fair electoral processes. During the polls on 7 October 2022, the role of the IEC came to the fore in terms of the extent of their preparedness for and actual performance in managing the electoral processes. Adopting a qualitative approach that relies on interviews with purposefully selected respondents and document analysis, this paper assesses these two main aspects of the IEC. The paper argues that compared to previous elections from 2012, the IEC does not seem to have been adequately prepared to manage the October 2022 elections, and as such, it had a poor performance this time.
The transition and formation of government after Lesotho’s 2022 elections
Authors: ‘Nyane Hoolo
Published: July 2023

The process of transitioning from one government to another and forming a new government after elections in Lesotho is often fraught with controversy and uncertainty. These problems can be attributed, by and large, to the lack of adequate rules and consistent constitutional practice. The 2022 elections have once again shone the spotlight on these longstanding problems. Like all other elections since 2012, the 2022 elections were inconclusive: no political party received an outright majority to form a government. Since the country uses a parliamentary system, the government depends on the confidence of the National Assembly and the life of the government is pegged to the life of Parliament. The end of the parliamentary term effectively means the end of the government. In terms of the Constitution, once Parliament is dissolved, elections must be held within three months. Within one month after the elections, a new Parliament must sit. While the Constitution provides for the appointment of the prime minister – the king appoints as prime minister a member of the National Assembly who will have the confidence of the House – there are no rules stipulating how the confidence of the House is to be determined. Likewise, the government’s position between the dissolution of Parliament and the forming of a new government is often opaque and precarious. This article examines these inadequacies in the context of the 2022 elections. The article uses content analysis – the examination of primary and secondary documents – to analyse the activities that took place during the transition and formation of a new government in the 2022 elections. The article concludes that the 2022 elections serve to confirm a longstanding problem of inadequate rules and consistent practice relating to the transition and formation of government.
Screening political party candidates and the implications for electoral performance
Authors: Letsie Tlohang W
Published: July 2023

The formation of the Revolution for Prosperity (RFP) party in March 2022 has radically altered Lesotho’s political landscape. Apart from the new calibre of political leadership, the party has, in line with its name, revolutionised some of the traditions long held by Lesotho’s political parties. Contrary to the closed primary elections that most parties use, the RFP introduced a combination of centralised and technocratic approaches in determining the list of party candidates for the October 2022 elections. With the former, the party reserved candidateship in eleven constituencies for persons appointed by the leader. Four front runners in the primary elections in the remaining constituencies would be subjected to various screening methods with the final determination to be made by the party leadership. The detractors have mocked the RFP’s approach as undemocratic and undermining the will of the people. The party also experienced internal resistance that led to it being taken to the law courts where some decisions were reversed. Using various data collection methods, this paper discusses the strategies used by the RFP and shows that much as they are not common in Lesotho, these strategies are not entirely new in politics as they are used in other democratic systems. An examination of the October 2022 elections results shows that despite the court challenges, the RFP’s candidate selection strategies had a positive impact on the party’s performance as well as on the profile of the resultant National Assembly.
Robust Topological Edge States in C6 Photonic Crystals
Authors: Borges-Silva Daniel , Costa Carlos Humberto , Bezerra Claudionor Gomes
Published: July 2023

The study of photonic crystals has emerged as an attractive area of research in nanoscience in the last years. In this work we study the properties of a two-dimensional photonic crystal composed of dielectric rods. The unit cell of the system is composed of six rods organized on the sites of a C6 triangular lattice. We induce a topological phase by introducing an angular perturbation ϕ in the pristine system. The topology of the system is then determined by using the so-called k.p perturbed model. Our results show that the system presents a topological and a trivial phases, depending on the sign of the angular perturbation ϕ. The topological character of the system is probed by evaluating the electromagnetic energy density and analyzing its distribution in the real space, in particular on the maximal Wyckoff points. We also find two edge modes at the interface between the trivial and topological photonic crystals, which present a pseudospin topological behavior. By applying the Bulk-Edge correspondence, we study the pseudospin edge modes and conclude that they are robust against defects, disorder and reflection. Moreover, the localization of the edge modes leads to the confinement of light and the interface behaves as a waveguide for the propagation of electromagnetic waves. Finally, we show that the two edge modes present energy flux propagating in opposite directions, which is the photonic analogue of the quantum spin Hall effect.
Optimization of Carbon Capture & Hydrogen Production via Steam Reforming: A Simulation-Based Case Study
Authors: Sakib Ahmed Nazmus , Shabab Ahnaf Tahmid , Ahmed Md. Firoz
Published: July 2023

Hydrogen has been considered a future energy carrier for decades and the demand for hydrogen in refineries is always upward due to the revival of new technologies. The steam methane reforming method is frequently employed because of its high hydrogen generation efficiency at a cheap cost and minimal negative impact on the environment. But depending on the type of feedstock, one unit of hydrogen generate 9-10 units of CO2 that is needed to be treated for environmental sustainability. Therefore, the optimization of hydrogen production and CO2 capture is very important to address. The simulation research was conducted to anticipate and optimize steam reforming using Aspen HYSYS. A conversion-type reactor was used to develop this simulation-based model. The primary goal of this work is to investigate and optimize the production efficiency of hydrogen and the mitigation of CO2 that is generated from the steam reforming process by varying process parameters. CO2 capture efficiency was investigated at the different yields for hydrogen production and was found that a maximum of 98.8% of the CO2 can be absorbed using the proposed carbon capture system. Later, the Aspen Energy Analyzer tool revealed potential improvements for energy and cost optimization.

Loneliness as a predictor of Internet addiction among adolescentes from Arab society in Israel
Authors: Nibal Shahin
Published: July 2023

Internet afecta a casi todos los aspectos de nuestras vidas. Puede ir acompañado de un uso excesivo y problemático e incluso de adicción. Lo que hará que los límites entre el mundo interior y el mundo digital se desdibujen. Los adolescentes que aún se encuentran en el período de desarrollo son los más vulnerables. Por lo tanto, el objetivo del estudio actual es examinar la soledad como predictor de la adicción a Internet entre los adolescentes árabes en Israel. La muestra de la investigación consistió en estudiantes adolescentes de secundaria y preparatoria de la sociedad árabe en el norte de Israel (n=382) de 12 a 17 años (M = 15.42, SD = 1.27). Alrededor del 65% de ellos eran niñas y alrededor del 35% eran niños. La muestra incluía adolescentes musulmanes, cristianos y drusos. Los resultados de la investigación indicaron que existe una correlación positiva entre la soledad y la adicción a Internet. Además, se encontró que el nivel promedio de adicción a Internet entre los niños (M=2.60, SD=1.03) es más alto que entre las niñas (M=2.60, SD=1.03), lo que significa que los niños son más adictos a Internet que las niñas. Los hallazgos también indican una diferencia significativa entre niños y niñas en el grado de soledad (t=2.653, p<0.01), se encontró que el nivel promedio de soledad entre los niños (M=2.56, DT=0.92) es mayor que entre los niños. niñas (M=2.31, SD=0.81), los niños reportan un mayor nivel de soledad que las niñas.
COMPARATIVE LEGAL ANALYSIS ON THE COMPETENCE OF THE INDONESIA’S FINANCIAL SERVICES AUTHORITY AND MONETARY AUTHORITY OF SINGAPORE ON THE ENFORCEMENT OF INSIDER TRADING LAWS
Authors: Fabian Jonathan  , Fajar Sugianto  , Michael Tomy
Published: July 2023

This article investigates the competencies of both Indonesian and Singaporean capital market supervisory and regulatory bodies, namely Otoritas Jasa Keuangan and the Monetary Authority of Singapore. It further assesses the effectiveness of each body in enforcing laws prohibiting insider trading specifically. It shall further evaluate the passiveness portrayed by the Indonesian counterpart when it comes to the eradication of day trading activities in the market as well as variables that are weighed in its implementation. A normative-empirical method is used for this article as it considers legal principles and legal systems, following a comparative approach. The materials relied on for this article include an interview with a capital market lawyer, an analysis of the law and other supporting documents, and a comparative study. The nature of competence for Indonesia and Singapore’s capital market supervisory and regulatory bodies is quite similar which adopt integrated approaches towards regulation and supervision of the capital market and with adequate authority to enforce their mandates. Since 2012, OJK has replaces the role of Bapepam-LK to administer the Capital Market Law as an independent body. OJK is responsible for enacting rules and other oversight of the sector.
CENTRAL BANK DIGITAL CURRENCIES IN THE INDONESIAN SETTING: QUESTIONS & CHOICES
Authors: Linnan David K
Published: July 2023

Central Bank Digital Currencies or CBDC have attracted increasing attention worldwide. Discussions take place chiefly at the institutional central bank level, and among financial and monetary economists, but now are moving into legal and political spaces. Meanwhile, Bank Indonesia or BI, the Indonesian central bank, has been an active proponent of a digital Rupiah for several years, seemingly focused on payment system improvements, problematic to the extent on-going digitalisation of the economy is not purely a payment system exercise.The Indonesian Parliament or DPR recently authorised in Law No. 4/2023 BI’s creation and management of a digital Rupiah, but open issues remain: (1) the DPR’s emphasis in its guidelines for the digital Rupiah contemplates currently only a domestic rather than crossborder digital Rupiah; (2) the DPR seemingly contemplated broader financial inclusion and more equitable development as a practical matter, while BI’s prior proposals seemed more focused on efficiency and banking sector; and (3) domestic CBDC’s introduction probably constitutes a dress rehearsal for an eventual international CBDC, so a planning function lies hidden. Digital Rupiah’s implementation presumably lies 12 to 24 months ahead, taking place under a new Indonesian President to be elected in 2024, implying new senior financial sector regulators as well. The best legal approach would be for BI to manage the digital Rupiah through external clearing and settlement institutions, and there are numerous international economic law complications in the hidden planning exercise if domestic is to become international digital Rupiah over time. Developing versus developed country CBDC concerns are simply different.

PENERAPAN BUDAYA 5S DALAM PEMBELAJARAN IPS SEBAGAI PENGUATAN KARAKTER SOSIAL SISWA
Authors: Puspita Ardiana , Widda Djuhan Muhammad
Published: July 2023

Berdasarkan hasil analisis data ditemukan bahwa penerapan budaya 5S dalam pembelajaran IPS guna memperkuat karakter sosial siswa meliputi kegiatan pembiasaan. Dalam membiasakan siswa menerapkan budaya 5S tidak terlepas dari bimbingan dan keteladanan/contoh yang dilakukan guru dalam menerapkan budaya 5S (senyum, sapa, salam, sopan, santun) agar ditiru oleh siswa. Penerapan budaya senyum, sapa, salam, sopan, santun ini membawa perubahan yang positif pada sikap dan perilaku siswa. semula siswa yang kurang menghargai temannya dengan membiasakan penerapan budaya 5S menumbuhkan karakter sosial pada diri siswa sehingga antar teman dapat saling menghargai, saling tolong menolong, tidak saling mencela. Hal ini menandakan bahwa penerapan budaya 5S dalam pembelajaran IPS dapat memperkuat karakter sosial siswa di MTs Al-Azhar. Adapun faktor pendukung penerpan budaya 5S guna memperkuat karakter sosial yakni tidak terlepas dari sumber daya guru dalam kegiatan belajar mengajar di kelas yang selalu memberikan motivasi, arahan, bimbingan, keteladanan, dalam membiasakan siswa untuk menerapkan budaya senyum, sapa, salam, sopan, santun. Selain faktor pendukung terdapat faktor penghambat penerapan 5S diantaranya dipengaruhi oleh pertama, faktor internal yakni faktor yang dipengaruhi dari dalam diri siswa sendiri yakni masih terdapat siswa yang belum sepenuhnya dengan rutin menerapkan budaya 5S. kedua faktor eksternal yakni lingkungan dimana siswa bermain, tumbuh dan berkembang juga berpengaruh pada pembentukan karakter siswa. Selanjutnya dari adanya penerapan budaya 5S di MTs Al-Azhar, karakter sosial siswa semakin diperkuat. Dampak penerapan dari budaya 5S yang dilakukan dengan rutin dapat menunjukkan perubahan perilaku siswa yang diinginkan. Adanya penerapan budaya 5S tersebut juga dapat memperkuat karakter sosial pada indikator penguatan karakter sosial yang dicapai yakni kemampuan siswa dalam bekerjasama, toleransi, menghargai dan menghormati, kepedulian dan solidaritas diantara siswa.

The embedment of multisize proppant in fractures and the creep behavior of the shale will affect fracture permeability, yet the combination of the two factors has not been well studied and understood. In this work, the impact of graded arrangement of multisize proppant on fracture permeability is studied considering proppant embedment and shale creep in a hydraulic fracture. The Hertz contact theory is used to quantify the depth of embedment for proppant with different particle sizes, and the Burgers model is used to describe the creep behavior of shale. Then, a permeability model considering the effects of multisize proppant embedment with shale creep is developed and verified. The results show that, under the combined effect of shale creep and proppant embedment, the reduction in permeability of the proppant arrangement with equal amount of three particle sizes is about twice that of two particle sizes. It also shows that there is an optimal Young’s modulus ratio that allows for minimal proppant embedment when the Young’s moduli of proppant and shale are in the same order of magnitude. Moreover, creep is positively correlated with loading pressure, loading time, and clay mineral content in the shale and there is a clear correspondence between shale creep, fracture width, and permeability variation. It is suggested that proppant type, size, mixing ratio, and fracturing parameters for shale reservoirs should be optimized by combining reservoir mineralogy and rock mechanics to reduce the cumulative effect of shale creep on long-term productivity. This work is useful for optimizing the hydraulic fracturing design for shale reservoirs and improving the efficiency of hydraulic fracturing to increase permeability.

Published: July 2023

Our study utilizes network science to examine how uneven vaccine distribution affects mass vaccination strategies in the United States. Using mobility network data and epidemiological models, we find that distributing a fixed quantity of additional vaccines across Census Block Groups (CBGs) can vary case count reductions by up to 200%. This highlights the impact of vaccination heterogeneity on mobility networks in epidemic outcomes. Our efficient algorithm identifies optimal vaccine distribution for maximum case reduction. Simulations show a possible 9.5% decrease in case numbers with just a 1% increase in the national vaccination rate if vaccines are optimally distributed. These results surpass other vaccine distribution models. Our findings underline the need for policymakers to understand the interaction between vaccination patterns and mobility networks, suggesting that grasping geographical vaccine uptake variations could be as crucial as raising the overall vaccination rate.

Published: July 2023

The most important phase to established communication between mobile station and base station is the Initial Network Entry Process. This process has vulnerabilities against malicious attacks that affect communication efficiency. Although several Initial Network Entry protocols are proposed, however most of them suffer from several weaknesses like vulnerabilities to varied attacks, low communication efficiency with using a high complexity of protocol structure. In order to overcome these shortcomings, we propose astrong mechanism and new method of authentication scheme using the elliptic curve digital signature algorithm. The proposed security protocol, named ESINEP “An Efficient and Secure Initial Network Entry Protocol”, used to share a secure key between mobile station and base station to authenticate each other and to secure communication. While designing ESINEP our main aims are assure: message integrity, source authentication, low communication cost, the fast verification and efficient exchange of messages. Finally, a formal security verification using Scyther tools concludes that ESINEP is secure against the existing attacks.

Multi-objective optimization problems with large-scale variables are the focus and difficulty of current research in the field of multi-objective evolutionary algorithms. In order to cope with the problem of "dimensional catastrophe", this paper proposes a large-scale multi-objective firefly algorithm based on reward and punishment mechanisms and adaptive dimensional reorganization. First, a reward and punishment mechanisms is proposed to make full use of the information of the solution itself, so that the population can break the constraint and rapidly approach the Pareto frontier, effectively improving the convergence of the population; then, an adaptive dimensional reorganization mechanism is proposed to select individuals with large differences according to different iteration periods to interact and learn from each other, effectively improving the diversity of the population. In the experimental part, to verify the effectiveness of the algorithm, the UF series and the variable expanded ZDT series, 15 test problems are selected for simulation experiments and compared with 8 advanced large-scale optimization algorithms, the results show that L-MOFA-RA has the advantages of fast convergence speed and high convergence accuracy, and the comprehensive experimental results show that compared with the comparison algorithm L-MOFA-RA has better optimization performance. The comprehensive experimental results show that L-MOFA-RA has better optimization performance compared to the comparison algorithm.
Meditation practice improves body balance compared to stability exercises alone

Published: July 2023

Sport and competitions stress athletes both physically and mentally. Physical training strengthens muscular and metabolic capabilities, while mental training reduces psychological load and negative emotions. Meditation practice helps athletes to reach better results in many sports, but evaluating only sport results makes it difficult to disentangle the specific effects of meditation contributing to performance. Our aim was to evaluate if meditation practice may benefit body balance, a basic skill relevant for action execution and performance. 81 high school students were trained in body balance for six weeks through balance and stabilization exercises and to stand on a fit-ball. 42 of them were trained in meditation, which practiced during the same six weeks (meditation group), the remaining 39 did not (control group). Core stability, tested before and after the training period, improved in both groups to a similar extent. On the other hand, the meditation group developed a much greater skill on fit-ball than the control group: the hazard rate of falling was reduced by 67 %. Our results suggest that for a more difficult task, meditation can increase learning and execution, and that introducing meditation in athletes' training routine may be of value for balance control and performance.
