Investigation of Corporate Social Responsibility in Sports within The Scope of Corporate Sustainability
Authors: KIZILGÜNEŞ Mine , KOÇAK Funda
Published: August 2021

The idea of corporate social responsibility dates back nearly a century, but it is not long ago that the concept was put into action by organizations and studied by researchers. While the first official examination of the concept dates back to the 1950s, it was in the 1980s that people began to question and expect social responsibility practices from organizations. It was the early 2000 that the concept was examined in the field of sports and attracted the attention of researchers. When the corporate social responsibility studies carried out within the scope of sustainability in the field of sports are examined, it is seen that the importance of such practices in terms of organizations is mostly investigated topic. In the research papers, it was also examined how the corporate social responsibility activities carried out by professional sports organizations were received by sports fans and stakeholders. In our study, the place of corporate social responsibility in the field of sports was investigated within the scope of corporate sustainability. When examining studies in the field, it is seen that sport are a valuable tool for sustainable development and corporate sustainability, and that sports organizations should include corporate social responsibility activities in their strategic plans. Considering it’s power to reach the society, it is thought that corporate social responsibility in the field of sports is an important field that needs to be worked on in order to ensure sustainable development and corporate sustainability.
LEGALIDADE, VINCULAÇÃO E DISCRICIONARIEDADE NA ADMINISTRAÇÃO TRIBUTÁRIA
Authors: Pereira de Sousa Domingos
Published: August 2021

A evasão fiscal e a necessidade de mais receitas no Estado Social colocam o problema do equilíbrio entre o poder de tributar e o dever de contribuir. A Administração Tributária precisa de uma margem de liberdade na avaliação e investigação das situações tributárias. Em contrapartida, o contribuinte necessita de ver compensado o aumento da discricionariedade com mais garantias, através do contraditório no procedimento tributário e, sobretudo, através de um controlo judicial efectivo e pleno dos actos tributários. Essencial é garantir que a discricionariedade não resulta em arbitrariedade, e evitar que a função tributária se desenvolva fora do Direito
A CONDIÇÃO NOS DIREITOS PORTUGUÊS E NORTE-AMERICANO. POSSIBILIDADE E IMPOSSIBILIDADE
Authors: Vargas Lurdes
Published: August 2021

O presente estudo desenvolve uma análise comparativa dos direitos português e norte-americano, procurando averiguar se nestes dois ordenamentos será admissível introduzir num contrato uma cláusula que faça condicionar todos ou parte dos efeitos desse contrato à ocorrência de um evento futuro e incerto. Concluindo-se que ambos os ordenamentos jurídicos em comparação oferecem essa solução, outras questões são colocadas: Se tal evento condicionante for desde o início impossível ou se tornar impossível, que sucede à cláusula e ao contrato? Há um regime especial aplicável a estes problemas? Que soluções oferece? No final do estudo, concluiu-se que a condição norte-americana se adapta a casos muito diferentes e o seu regime também. Embora imprecisa nos limites, tem um regime de não verificação e impossibilidade da condição bastante completo, oferecendo soluções de muito bom senso. O regime jurídico português da condição é mais preciso, aparentemente mais claro e os contornos da condição são também mais precisos. Mas o regime jurídico da impossibilidade da condição é mais rígido e perante os casos concretos nem sempre oferece uma resposta clara e justa.
RESPONSABILIDADE CIVIL DO ESTADO POR DANOS DE CORRENTES DO EXERCÍCIO DA FUNÇÃO JURISDICIONAL: REGIME JURÍDICO-SUBSTANTIVO E JURÍDICO PROCESSUAL
Authors: Lucas Ferreira de Almeida Francisco Manuel
Published: August 2021

O acórdão pronunciou-se sobre o tema da responsabilidade civil do Estado por danos decorrentes do exercício da função jurisdicional, com base em erro judiciário. Concluiu o aresto que a ilicitude tem de advir da prévia revogação da decisão danosa pela jurisdição competente, como pré-requisito dessa responsabilização. Revogação essa que implique o reconhecimento judicial do erro, com as caraterísticas de manifesto, quando de direito, ou de grosseiro, quando de facto. O comentário assenta no facto de o novo regime legal, entrado em vigor em 1 de janeiro de 2020, ter vindo acabar com a distinção entre decisões (supostamente) violadoras do direito europeu e decisões (alegadamente) violadoras do direito interno, ao tornar passíveis de recurso de revisão quaisquer decisões transitadas em julgado com base em (reconhecido) erro judiciário.

Realizing the Horn of Africa in a New Context: Challenges and Opportunities for Peace in Somalia
Authors: Abdullah Liban
Published: August 2021

In 1991 growing political pressure and infighting led to the collapse of the Somalia government. Key institutions of governance disintegrated, and public services could no longer be provided. The Somali National Army was amongst the key institutions that collapsed and, in its place, warlords and clan militias emerged to fill the gap. Henceforth for over two decades, these non-state actors competed over control of both political and economic power while other radical organizations such as Al-Shaabab emerged with an objective to establish an Islamic state. This instability thus led to displacement of populations, insecurity both at the domestic and regional level. This thesis seeks to examine how the collapse of Somali impacted the military and why moving forward in the transitional period, reforming the military is vital to the future of Somalia and geopolitical and economic stability. The thesis adopts state building and realism as it theoretical frameworks and argues for the need of military reforms within the conceptual frameworks of security reforms. Specifically, the thesis reiterated that if the Horn of Africa and the greater Eastern Africa region is to experience geopolitical and economic stability, then the SNA should undertake key reforms in order to reinforce its capacity to resolve domestic instability in Somalia which is the causal factor in geopolitical and economic instability caused by threats such as terrorism, piracy, and bilateral tensions between regional states. The study suggests that reforms in the military such institutional capacity building, coordination of security assistance, and establishing civilian oversight over military is critical in reviving the capacity of SNA and with it, the first step towards restoring regional stability.

Da fissão nuclear aos elementos transurânicos
Authors: Silva Vinícius Carvalho da
Published: August 2021

Com a publicação do artigo de Einstein de 1905 acerca da equivalência entre massa e energia iniciou-se um novo programa de pesquisa. As tentativas de confirmação da teoria exigiam o bombardeamento de núcleos atômicos, culminando, na década de 1940, com a vindicação de descoberta da fissão nuclear. O físico italiano Enrico Fermi teria obtido tal resultado em seu laboratório em Roma antes do grupo alemão de Hahn, Strassman e Meitner. Ainda assim, negou a hipótese da fissão nuclear, apresentada anos antes pela química alemã Ida Tackle Noddack e propôs a descoberta de elementos transurânicos para explicar seus resultados experimentais. Neste artigo investigamos o que levou Fermi a rejeitar a hipótese de Noddack. Defenderemos que apenas uma abordagem complexa que conjugue múltiplos fatores pode nos aproximar de uma compreensão histórica mais arrojada da realidade social da pesquisa científica.

As pesquisas elétricas de Luigi Galvani, que culminaram com a formulação da teoria da eletricidade animal e, posteriormente, suscitaram uma das mais emblemáticas controvérsias na história da ciência com Alessandro Volta, evidenciam uma profícua relação entre hipóteses e experimentações. Este artigo busca contextualizar os estudos iniciais de Galvani fazendo vínculos de suas experimentações com a ideia baconiana de experientia literata e, sobretudo, com a concepção de experimentação exploratória na perspectiva de Friedrich Steinle. Ao final, apresenta algumas implicações desse resgate histórico-filosófico para um ensino sobre a ciência.
Reviewing the Review: An Assessment of Dissertation Reviewer Feedback Quality
Authors: Lehan Tara , Hussey Heather , Mika Eva
Published: August 2021

Throughout the dissertation process, the chair and committee members provide feedback regarding quality to help the doctoral candidate to produce the highest­-quality document and become an independent scholar. Nevertheless, results of previous research suggest that overall dissertation quality generally is poor. Because much of the feedback about dissertation quality provided to candidates, especially those in online learning environments, is written, there is an opportunity to assess the quality of that feedback. In this study, a comparative descriptive design was employed using a random sample of 120 dissertation reviews at one online university. Common foundational errors across dissertations and strengths and growth areas in reviewer feedback were noted. Whereas reviewer feedback quality was acceptable overall, there were significant differences across reviewers. Based on the findings, increased discourse, standardization of psychometrically sound measures that assess reviewer feedback quality, and ongoing training for faculty members who review dissertations might be warranted.
Towards a theory of the Ecology of Reflection: Reflective practice for experiential learning in higher education
Authors: Harvey Marina , Coulson Debra , McMaugh Anne
Published: August 2021

Reflective practice is widely adopted across the field of experience-based learning subjects in higher education, including practicums, work-integrated learning, internships, service learning and community participation. This adoption of reflective practice implies that it supports student learning through experience. When reviewing the evidence for the role of reflection for learning, it became evident that not only was there no clear agreement about the definition of reflection, there has been little theoretical development in this area. An integrated participatory action research and ecological approach was adopted to build a theory about the ecology of reflection for learning through experience. Through this process the assumptions, or truths that are taken for granted, that underpin the new theory were declared and substantiated. Key concepts and the principle tenets of the theory were then identified and defined, leading to an overview of the ecologies of the learner, the learning context and the experiential learning context.
Reflection in Medical Education
Authors: Hargreaves Ken
Published: August 2021

This paper offers a medical-education perspective that I will hope complement other disciplinary perspectives in examining the value of reflection for learning in tertiary education. The paper outlines some of the theoretical strands of reflective practice facilitated in a unique course subject for professionalism and patient safety, within the new spiral curriculum at Leeds University School of Medicine. The material presented in this paper outlines some of what is delivered during the medical students’ interactive sessions; this material is continually modified based on feedback from both students and learning facilitators.

The paper discusses why both students and clinicians need to reflect, some of the theoretical dimensions and models and examples from the Leeds context of how reflective competence can be progressively developed over the course of an undergraduate program.

The focus of the final section suggests directions for reflective practice in the future, where reflexivity takes the form of more collective endeavours requiring some change in culture and perceptions of professional identity. The paper concludes with the proposition that collaborative forms of reflection need to include more involvement of patients, interprofessional communities of practice and the use of learning from other disciplines; all of these require different levels of thinking and different ways of working.

Published: August 2021

During a period of massive upheaval to the higher education sector, the traditional academic role has undergone considerable change. One element of these changes has been the broad introduction of Education-Focused (EF) or equivalent academic positions, which focus on educational excellence, with a requirement for high quality teaching and associated scholarly research. This paper reports on the reflections of a group of bioscience academics as they transitioned from a traditional teaching and research position to an EF academic position at a research-intensive Australian university. Through analysis of written narratives, the insights of these academics, including their concerns and potential opportunities, were explored. Given the global trend toward EF and similar positions, this study provides valuable insights into the evolving nature of academic identity, and in particular the role of EF academics in enhancing curricula and in providing educational leadership. Additionally, this study provides perspective for universities to plan optimally for future introduction of EF positions. Facilitating opportunities for support, mentorship and career progression of EF staff will promote best practice in teaching and learning.

Cardiac Structural Alterations of Acromegalic, Without Alteration in Cardiac Function, Evaluated by Doppler Echocardiography with Speckle Tracking
Authors: Oliveira Marília Matos , Jorge Lara Beatriz Hallal , Tomé Janaíne Machado , Ferreira Beatriz Pires , Borges Maria Candida Calzada , da Silva Adriana Paula , Ferreira José de Oliveira , Borges Maria de Fátima
Published: August 2021

BACKGROUND: Acromegaly is most commonly caused by growth hormone secreting pituitary (GH) macroadenoma. Cardiovascular events are the leading cause of death in this population.

OBJECTIVE: To analyze the cardiac structural and functional changes in patients with acromegaly and to correlate the findings with the concentrations of GH and IGF-1 post treatment and with the presumed time of disease.

METHOD: A quantitative study involving 19 individuals with acromegaly, 10 with inactive disease and 9 with active disease and 16 healthy individuals, matched by sex and age. Age ranged from 19 to 78 years. Two-dimensional echocardiogram and speckle tracking were performed.

RESULTS: Mean left ventricular mass index (LVMI) were significantly higher in acromegalic patients (89.1 ± 27.9) compared to the control group (66.9 ± 15.7) (p = 0.015). There was a direct correlation between IGF-1 mean concentration and left ventricular systolic volume (LVSV) in acromegalic patients (r = 0.64; p = 0.004) even when the disease was inactive (n=10; r = 0.9; p = 0.002) and between IGF1 mean concentration and left ventricular diastolic volume (LVDV). The left ventricular ejection fraction (EF) and the global longitudinal strain (GLS) did not differ between groups (p> 0.05).

CONCLUSION: Although patients with acromegaly had higher LVMI, they did not show difference in GLS indicating a small chance of progression to systolic disfunction. Direct correlation between IGF-1 and LDVD and LVSV demonstrates the relevance of a good hormonal control to reduce cardiac changes.
Gender Differences and the Five Facets of Conspiracy Theory
Authors: Popoli Gary , Longus Angel
Published: August 2021

Although research examining conspiracy theory beliefs has been examined, there is conflicting literature on the relationship between gender and conspiracy thinking. Before this study, little research has been conducted on the differences between males and females in each of the five facets of conspiracy theory. This study was designed to investigate differences in gender as they pertain to government malfeasance (GM), malevolent global conspiracies (MG), extraterrestrial cover-up (ET), personal well-being (PW), and control of information (CI). It was hypothesized that there are statistically significant differences between females and males when it comes to conspiracy theory beliefs for each of the five facets. Archival data from 2016 containing responses to the Generic Conspiracist Beliefs Scale was analyzed. Results supported the main hypothesis of this investigation that significant differences do, in fact, exist between females and males in all five facets of conspiracy theory: government malfeasance, malevolent global conspiracies, extraterrestrial cover-up, personal well-being, and control of information. In addition, this study revealed that females score higher than males in all facets. In general, a computed total conspiracy belief score demonstrated that females (M = 45.10, SD = 15.07) were significantly higher than males (M = 42.13, SD = 15.90). Nevertheless, some recent research has reported that women were significantly less likely than men to engage in ‘conspiratorial thinking’ and endorse a conspiracy about the COVID-19 pandemic of 2020. These findings may be suggesting a change in direction for gender differences and a need for further research.

Sustainable soil stabilization using combination of geotextile, fly-ash and saw dust for pavement subgrade
Authors: Sahak B. , Singh M. , Adhikari A. , Hussain S.
Published: August 2021

Purpose: This paper investigates the combined effect of fly ash, sawdust and geotextile in stabilizing the soil. Design/methodology/approach: A thorough geotechnical testing was carried out in order to study the potent characteristics of soil and soil mixes. The present investigation was set up in two stages. In the first stage, effects of fly ash (5, 10, 15 and 20%), sawdust (2.5, 5 and 7.5%) and layers of geotextile placed at different depths were studied separately to determine their effect on soil stabilization. In the second stage, fly ash, sawdust and geotextile were mixed with soil sample in order to obtain the optimum dosage which can be used for stabilization of soil i.e. their combined effect as stabilizer on soil stabilization. Findings: It was observed that by introducing fly ash, sawdust and geotextile to the soil, the CBR values increase and thickness of pavement layer decreases. It also decreases the amount of stress on subgrade leading to enhancement of pavement stability with cost effectiveness. Research limitations/implications: Economical use of industrial waste has been proposed in the present research which otherwise prove to be a malady to climatic change and human health. From the study, an optimum dosage of fly ash (2.5%) and saw dust (5%) and depth for geotextile (6 cm) has been proposed. Originality/value: The article explores the possibility of a ternary blend, i.e., geotextile, flyash and saw dust on effectively stabilizing pavement subgrade. Limited literature was available to address the issue of utilizing the industrial wastes that otherwise pose disposal issues.

Investigation of the influence of the physicochemical characteristics of waste on the quality of liquid fuel products from them, obtained by multi-loop recirculation pyrolysis
Authors: Markina L.M. , Zholobenko N.Yr. , Ushcats S.Yr.
Published: August 2021

Purpose: To study the properties of MSW generated in Ukraine in order to ensure their most efficient processing using the multi-loop recirculation pyrolysis technology in order produce a liquid fuel product. Design/methodology/approach: The problem' study of MSW accumulation in the world countries was carried out on the basis scientific databases PubMed, ScienceDirect, Mendeley, ResearchGate, Google Scholar for the corresponding keywords. The MSW properties generated in Ukraine were determined in accordance with the current standards to determine the specific properties of materials. For the experimental study, 3 types of solid organic waste mixtures were compiled, the composition of which characterizes the variable data on the accumulation of household and industrial waste of Ukraine. The quantity and quality of the liquid product obtained was determined using certified equipment. Findings: The tests revealed that the composition of the solid organic waste mixture when disposing of them by the multi-loop recirculation pyrolysis method has little effect the composition and properties of the obtained liquid hydrocarbon product; the total time of complete degradation for different mixtures of composite materials (mixtures of polymeric substances) is 180-250 min; the correct selection of the temperature of the circulation system makes it possible to produce a gaseous or liquid product which can then be used as an alternative fuel. Research limitations/implications: Current study of solid organic waste degradation was carried out by the multi-loop recirculation pyrolysis method. The experimental waste mixtures did not contain very wet waste of small fractions. Practical implications: The technology of circulating pyrolysis makes it possible to change the qualitative and quantitative composition of the obtained liquid hydrocarbon product, which is a potential fuel, irrespective of the composition of the solid organic waste mixture.Originality/value: It has been experimentally established that the quality of the liquid hydrocarbon product obtained by the multi-loop recirculation pyrolysis process does not depend on the composition of the solid organic waste mixture, but depends on the process' duration and the third circuit' temperature of the multi-loop recirculation system.
Improving the efficiency of fluidized bed comminution of limestone samples
Authors: Wysocki D.
Published: August 2021

Purpose: The aim of the research was to describe the properties and methods of using
limestone for desulfurization of flue gases and to analyse the process of fluidized bed
comminution and the influence of selected parameters and stand modification on quality of
product of fluidized bed comminution.
Design/methodology/approach: Tests of the grinding process on the fluidized bed were
carried out using a modified fluid bed mill for operational variable parameters and their
results were compared with the results received before modification. The modification of
the test stand consisted of increasing the height of the grinding chamber, which ensured an
increase in the volume of the fluidized layer where the grinding process takes place.
Findings: Main parameters that determined the effects of comminution in the analyzed
case were: overpressure of working air and the rotor speed of the classifier. The introduction
of the modifications of the test stand ensured an increase in the volume of the fluidized layer
in which the grinding process takes place. As well as a greater gravitational classification,
which caused larger grains to be stopped in the grinding chamber and shift of characteristics
of grain compositions towards finer grains.
Research limitations/implications: It is assumed that the diameter of sorbent grains
used in the fluidized bed can not exceed 6 mm. The granularity of the offered sorbents
ranges from 0.1 mm to 1.2 mm. The quality of the desulfurization process depends on the
overall granulation of used sorbent grains.
Practical implications: Appropriately selected sorbent grains used in wet and dry flue
gas desulphurisation plants ensure improved efficiency of the desulphurisation process and
lower operating costs of the installation.
Originality/value: Thanks to the comminution method used, a sorbent is obtained without
impurities and with an increased specific surface, which can be used in fluidized bed boilers.

The rhizome of Kaempferia galanga has been known to contain ethyl p-methoxycinnamate (EPMC) (1) as a main component, which has anti-inflammatory properties. Previously we have reported the structural modification of EPMC (1) to form another ester, nitrostyrene, and cinnammamide derivatives and then studied their structure-activity relationships as anti-inflammatory agent. In continuing our research, in this paper, we report the microwave-assisted Claisen-Schmidt condensation of EPMC (1) to synthesize a series of p-methoxystyryl ketones followed by a study of their anti-inflammatory activity. The reaction begins with microwave-assisted cleavage oxidation of hydrolyzed product of EPMC, p-methoxycinnamic acid (2) with Ca(NO3)2 for the synthesis of p-methoxybenzaldehyde (3). Furthermore, 3 was reacted with acetophenone, ethyl methyl ketone and acetone via microwave-assisted Claisen-Schmidt condensation for the synthesis of (E)-1-(4-methoxyphenyl)-3-phenylprop-2-en-1-one (5a) (E)-1-(4-methoxyphenyl)pent-1-en-3-one (5b) and (E)-4-(4-methoxyphenyl)but-3-en-2-one (5c), respectively. The reaction products were characterized using spectroscopic techniques and were then tested for anti-inflammatory activity using in vitro anti-denaturation of protein assay. It was found that converting EPMC (1) to 5a and 5b reduced anti-inflammatory activity, while 5c retained anti-denaturation activity with an IC50 of 72.8 µg/ml.
Changing Workplace Concepts

Published: August 2021

As I’ve quipped more than a few times to colleagues over the past year-and-a-half of COVID-19 restrictions, I’ve been practicing for a pandemic for more than 20 years. I am all too familiar with the pros and cons of working from home over extended periods. I was a pioneer in that arena, starting in the days (about 1999) when using a modem and my home telephone line to dial into the Internet was a technology breakthrough. I couldn’t have started my at-home business without that outside link to the world and a way to exchange digital files with my designer, who had moved to the other side of the continent. But, even with the blistering speed that fiber-optic cabling now provides for efficiently exchanging ever larger files between us (we still work together and we still live far away from each other), I appreciate more than most the value of working face-to-face daily with colleagues.

Inficionada en su discursividad, en sus aspectos teóricos metodológicos y pragmáticos por la posmodernidad que hoy parece declinar, fue objeto de diferentes alteraciones.   Por su parte, la disrupción pandémica actual, es seguro que  le movilizará aún más.  Se vislumbra allí la necesidad de  una re-semantización, y la  posible generación de un neologismo. Un análisis “crítico” en sentido estricto  que opere dentro de un marco interdisciplinario,  permite apreciar diáfanamente el nexo Derecho con Literatura, y la matriz narratológica del primero. Se abre paso así para poder considerarlo una forma Literaria arquetípica que se despliega en un parquet narrativo. Por otro lado, una percepción hermenéutica como instrumento cognitivo, comprensivo-interpretativo y metodológico se reivindica como valiosa  y necesaria para el Derecho de estos tiempos, pues contribuye a mitigar además, su consabida  opacidad que de seguro tiende a aumentar en contextos disruptivos.

Published: August 2021

Neste artigo, abordamos as mediações que atravessam os e-sports e o live streaming de jogos a partir do entendimento de que essas práticas profissionais implicam arranjos midiáticos distintos. As principais chaves teóricas foram o modelo de múltiplas mediações (OROZCO-GOMES, 2000) e o conceito de performance (SCHECHNER, 2003). Os procedimentos empíricos envolveram a análise quanti-qualitativa de 20 transmissões de um pro-player e streamer brasileiro. Entre os resultados, destacamos que as principais distinções entre as duas práticas estão relacionadas às mediações ludo-tecnológicas e de transmissão, seguidas pelas mediações situacionais. E-sports e streaming demandam diferentes competências, mas o streaming de jogos não requer menos profissionalismo que os campeonatos.
Crítica ao modelo de desenvolvimento rural de Olhos D’água, município de Uruguaiana (RS): a voz dos agricultores
Authors: Goñi Liana Mendonça , Hernández Jaime Morales
Published: August 2021

O objetivo do artigo é analisar o modelo de desenvolvimento rural do distrito Olhos D’Água, bem como os diferentes agir e reagir, práticas e discursos dos agricultores e pecuaristas familiares da região de Olhos D’água. Trata-se de um estudo de caso, com abordagem qualitativa e exploratória. Para tanto, a pesquisa consiste na união de duas perspectivas metodológicas: perspectiva etnográfica ator-rede Latour e Woolgar (1997), e a perspectiva orientada desde os atores de Long (2007). A partir das análises discursivas e documentais foi possível ressaltar as diferentes agriculturas, os diferentes graus de mercantilização e as diferentes racionalidades e modos de vidas no âmbito rural da região. Ao final do estudo conclui-se que a solução ao crescimento econômico é de ordem hegemônica para todas as realidades rurais, descartando a cada território o potencial das diferentes configurações sociais/produtivas, econômicas e ecológicasos locais. Nas mesmas características de “atrasados” e “estagnados” em que os pecuaristas familiares e a pecuária familiar foram forjados, há subsídios empíricos a pensarmos em estratégias desde essas racionalidades e modos de vida.

DEVELOPMENT OF BONOBO ALGORITHM AND ITS APPLICATION FOR OPTIMAL COORDINATION OF DIRECTIONAL OVERCURRENT RELAYS IN POWER SYSTEMS
Authors: ABDELHAMID MOHAMMED , KAMEL SALAH , SELIM ALI , MOHAMED MOHAMED , AMED MAHDROUS , ELSAYED SALAH
Published: August 2021

In this paper, an improved Bonobo optimization algorithm (IBO) is proposed to solve the optimal coordination of directional overcurrent relays (DOCRs) problem. This problem is important for power system protection. It is considered a nonlinear and highly constrained optimization problem. IBO aims to improve the performance of the original Bonobo optimization algorithm (BO) using Levy flight distribution and three leaders selection. Both BO and IBO are utilized to develop two solvers for optimal coordination of DOCRs. The 15-bus and 30-bus test systems are used to validate BO and IBO in minimizing the total operating time of relays with satisfying the operational constraints. The results of the proposed IBO algorithm have been compared with the original BO algorithm and other well-known algorithms. The obtained results confirmed the effectiveness and superiority of the proposed IBO algorithm compared with the other algorithms in minimizing the total operating time of relays for the optimal coordination of DOCRs.

Keywords: Directional overcurrent relays; Optimal coordination; Improved Bonobo algorithm; Levy flight distribution; Three leaders selection.
JEREZ-LANTEIRA MINING COMPANY, GRANADA. ORIGIN AND HISTORY OF THE HYDRAULIC PLANT FOR THE EXPLOITATION OF COPPER ORE IN THE 19TH CENTURY
Authors: GUERRERO RUIZ JUAN CARLOS , MARTIN CIVANTOS JOSE MARIA
Published: August 2021

In this article we will get to know an old hydraulic plant of a mining industry, very unique, which transformed hydraulic energy into pneumatics to supply compressed air to a copper mine and its smelter. It was located in the Granada region of the Marquesado del Zenete, and built in 1889 by the colonial European mining industry. To do this, we delve into its historical origin, and analyze this original technological project that allowed a new energy transformation system. Directed and executed by a series of engineers, metallurgists, businessmen and peasants, who through their work and will were participants in the industrialization process in Spain with the development of machinery and socialized work that will change a way of life.
These remains today make up an industrial heritage at risk of disappearing. Living memory of what our mining industry was with the development of engineering and its social, identity and cultural values.

The article demonstrates a case of diagnosis of a rare variant of primary skin lymphoma, namely of primary cutaneous CD4+ small/medium-sized pleomorphic T-cell lymphoma with an indolent course. The diagnosis of SMPTCL is based on the combination of the clinical picture, histological and immunomorphological data. A 70-year-old patient presented at the clinic with complaints about tumor-like formations on the skin of the face and back accompanied by moderate itching. The diagnosis was verified by pathomorphological and immunohistochemical studies of the biopsy of the affected skin. The presented clinical case emphasizes the importance of doctors’ clinical oncological alertness and the need for clinical and laboratory examination of the patient using modern histological and immunohistochemical methods for studying the skin biopsy.

Owing to challenges encountered by mesh-based CFD methods when simulating large material deformation, a number of meshfree methods have been presented. The optimized transportation meshfree method is a newly developed meshfree method, but it inherits the advantage of the finite element method in boundary treatment and thus having great potential applications in surface tension effect simulation. By adding the surface tension potential into the Lagrangian, the resulting generalized force acts on fluid surfaces exactly. The axial symmetry treatment is also discussed. By simulating several benchmark cases such as two- and three-dimensional Poiseuille flow, static and vibrating drop and drop deformation, the advantages like precision and convergence of the optimized transportation meshfree method in simulating surface tension effect are verified.

It is difficult to obtain bulk amorphous alloys experimentally due to the limitation of cooling technology and the ability to form amorphous alloy. However, the rapid cooling of nano-droplets is relatively easy, so the simulation research of nano-droplets is easier to verify experimentally. In this work, the molecular dynamics simulation for the rapid cooling of Cu64Zr36 nano-droplets of different sizes is conducted at a cooling rate of 1.0 × 1012 K/s, and the evolution of microstructure is analyzed in terms of the average potential energy, the pair distribution function, the three-dimensional visualization, and the largest standard cluster analysis. The analysis of the energy curves and the characteristic length for short-range-ordered microstructure show that the solidification process for all nano-droplets undergoes liquid-liquid transition and liquid-solid transition, and finally forms amorphous nanoparticles. Comparing with the icosahedron, the evolution of the topologically close-packed (TCP) structures can reflect the basic characteristics of phase transitions effectively. Based on the evolution of TCP clusters, the entire solidification process of nano-droplets can be divided into four stages: embryo, aggregation, growth and coarsening. The TCP structure embodies the basic structural characteristics of amorphous nano-droplets and particles, which is of great significance in perfecting the solidification theory.
