INFLUENCE OF SIGHT DISTANCE CHARACTERISTICS ON SAFETY OF INTERSECTIONS USING SURROGATE SAFETY MEASURES
Authors: Sushmitha Ramireddy , Bhanu Prakash Reddy Vattipally , Ravishankar KVR
Published: October 2023

Recent road accident statistics indicate that more than 30% of accidents occur at intersections. Whereas, total percentage of intersections present in the entire road network is less than 2%. From design point of view, one way to ensure reduction of accidents at intersections is to provide sufficient sight distance and clear sight triangles. However, it was observed that even when minimum sight distance is provided, it does not ensure non-occurrence of accidents because available sight distance at intersection changes with time. Hence there is a need to understand the effect of sight distance characteristics on safety at uncontrolled intersections. From safety studies, it was observed that crash data is highly unreliable as it is generally underreported.  Hence in the present study, surrogate safety measures were used instead of crash data. To accomplish the study objectives, six uncontrolled three-legged intersections were selected. Geometric data such as sight distance was measured as per IRC SP 41 (1994) guidelines. Traffic data collection at each intersection was carried out using videography method. From the recorded videos, volume data, speed data, and Post Encroachment Time (PET) data were extracted manually. The effect of various geometric and traffic factors on the critical conflict rate was studied using correlation and regression analysis. From the models developed, it is observed that for every 1 unit increase in logarithm of major and minor road sight distance, critical conflict rate decreased by 18.14% and 33.56%, respectively. Also, it was found that, the available sight distance is far shorter than the design/minimum sight distance specified by IRC SP 41 (1994).
ROBUST EXTREME RETURN LEVEL WITH POWER NORMALIZATION FOR EXTREME EVENTS: APPLICATION OF REAL HYDROLOGY DATA
Authors: Belhajjam Abdellah , Mohammadine Belbachir , Elouardirhi Saad
Published: October 2023

In statistical studies of rare and catastrophic phenomena the distribution of generalized extreme values under linear normalization is always chosen as the appropriate model. It used to estimate the probabilities of events that have not yet been observed. Recently, the extreme value theory (EVT) received a lot of attention both theoretically and practically using just the classical linear model (L-Model) or linear normalization of the maximum to estimate return level. So, in this paper we propose a new multiplicative model based on the distribution of generalized extreme values under non-linear normalization, whose purpose is to raise the strong and weak points between these two models. Our main goal is to use our multiplicative model (P-model) to calculate the return level, as well as the associated confidence interval. The diagnostic fit, test and statistical inference to compare the two models (linear and non-linear) are studied. Finally, a data analysis and discussion are applied at first on real hydrological data for Morocco and South of Australia, then on water levels of lake Erié in Canada. The results show that our multiplicative (non-linear) model is more adaptive because it takes into account the variation of the return period.
HYDROGEN AND METHANE GAS CONTENT IN SYNGAS FROM THE PYROLYSIS OF MELALEUCA CAJUPUTI AND SHOREA WOOD
Authors: Suprianto Teguh
Published: October 2023

The increasing demand for energy and the depletion of fossil energy supplies require research to find renewable energy sources. Biomass is a very potential energy source and biomass gasification is a technique to produce syngas. Melaleuca Cajuputi (Gelam) and Shorea sp (Meranti) are one of the types wood plant that are widely available in Indonesia. This study aims to reveal the potential of biomass from swamp-growing plants, Melaleuca Cajuputi, and land-growing plants, Shorea, through a gasification process to produce syngas containing hydrogen and methane gas.

Pyrolysis of biomass, Melaleuca Cajuputi and Shorea sawdust, using a fixed bed reactor at a temperature varying from 200 °C to 450 °C with a heating rate of 10 °C/minute for one hour. Hydrogen gas and methane gas resulting from pyrolysis were analyzed to determine the characteristics of the syngas produced. FTIR test was performed to support the experimental analysis.

The experimental results show that Melaleuca Cajuputi wood has a lower peak FTIR intensity than Shorea wood. Melaleuca Cajuputi produces more hydrogen, while Shorea wood produces more methane gas. The highest hydrogen gas content was produced from Melaleuca Cajuputi and Shorea at temperatures of 315 °C at 1746 ppm and 1503 ppm at 367 °C respectively. Meanwhile, the highest methane gas content was produced by Shorea and Melaleuca Cajuputi wood, 200,000 ppm at 370 °C and 63,200 ppm at 318 °C respectively. The intensity of functional groups from biomass affects the gas produced from pyrolysis.

This work reported the use of microwave vulcanization coupled with Dunlop process to prepared natural rubber latex foam (NRLF). Optimization of microwave heating for curing step was firstly carried out using a commercially available domestic microwave oven. The processing window and optimum condition for making NRLF were obtained.  The optimum power and time of the irradiation were found at 600 W and 6 min, respectively. Using the optimum microwave vulcanization, effects of stirring time (2, 4, 6, 8, and 10 min) and speed (650, 950, 1250, 1550, and 1850 rpm) of foaming step on cell structure, bulk density, compressive properties, and hardness of NRLFs were investigated. Generally, the increases in the stirring time and speed in foaming step both gave rise to the volume of the air incorporated into the latex compound.  This resulted in the increases in the bulk density and the number of cell but, the decrease in foam cell size. The stirring speed in a range of 950 to 1550 rpm was successfully used for preparing the NRLF. Too low and too high foaming speeds caused unstable latex compounds and failed to produce NRLF. The foam cell structure changed dramatically as the foaming speed increased. The foam mechanical properties, both compressive strength and hardness, were found to be linearly related to the foam bulk density.

Published: October 2023

This study aims at the application of the prepared Polymer Nanocomposite in the field of solid-state optoelectronic devices. Polymer Nanocomposite was prepared by incorporating iron nanoparticles, synthesized random Copolyester (BCTP), and Polypyrrole by Insitu chemical polymerization method. The application of the synthesized random Copolyester with wide biological activity due to bis chalcone moiety can also be extended to the optoelectronics field. The Copolyester (BCTP) was subjected to spectral analysis such as Fourier Transform Infrared Spectroscopy (FTIR) to confirm the chemical structural orientation. The Iron nanoparticles, Polypyrrole, and polymer nanocomposite were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and powder X-ray Diffraction (PXRD). The FTIR spectroscopy confirms the formation of polymer nanocomposite by the prominent shift in stretching frequency from the starting materials taken. Powder X-ray Diffraction was used to determine the Iron Nanoparticles’ average crystallite size. The structural morphology of iron nanoparticles, Polypyrrole, and polymer nanocomposite were identified by Scanning electron Microscopy. The SEM images gave the view of Iron nanoparticles, Polypyrrole was seated in the Polymer matrix. The specific capacitance for the newly synthesized Polymer Nanocomposite was found to be 58.88 F/g by Cyclic Voltammetric analysis. The electrochemical behavior of the random copolyester (BCPT), Iron nanoparticles, Polypyrrole, and polymer nanocomposite was carried out by Impedance analysis. This confirms the Polymer Nanocomposites were conducting nature with good ionic conductance of 6.89 × 10-5 S cm-1.

The aim of this study is to evaluate the dose‑dependent effect of bee venom (BV) on behavioral functions in rats and the physiological role of leptin in the prefrontal cortex, hippocampus, and amygdala tissues. Adult Sprague‑Dawley male rats were used in the experiments. The rats were divided into three groups of control, 0.1 mg/kg BV, and 0.5 mg/kg BV. The rats were injected with BV subcutaneously for 15 consecutive days. The open field test (OFT), the elevated plus maze test (EPM), and the forced swimming test (FST) were performed as behavioral assessments. Animals were sacrificed, and brain regions were removed. Leptin levels were measured in various brain regions by ELISA. In the OFT, the total distance and speed for the 0.1 mg/kg BV group increased compared to controls and the 0.5 mg/kg BV group. In the EPM, the 0.1 mg/kg BV group remained in the open arm for a significantly longer period of time compared to the other groups. In the FST, the 0.5 mg/kg BV group was more mobile than the other groups. Leptin levels in the prefrontal cortex were significantly higher in the 0.1 mg/kg BV group compared to the control and 0.5 mg/kg groups. There were no significant differences between groups in hippocampus and amygdala leptin levels. The results of the study show that BV has a positive effect on behavioral parameters. BV may have a positive effect on anxiety‑ and depression‑like behaviors by increasing leptin levels in the prefrontal cortex.

Considerações normativas para prever o comportamento à punção de lajes lisas do tipo Bubbledeck
Authors: Escóssio Lucca Adib Reis de Souza , Leite Jonas dos Santos
Published: October 2023

O presente trabalho discute, sob a perspectiva de uma análise qualitativa dos critérios atuais de dimensionamento de lajes do tipo bubbledeck. Para consumar a pesquisa, foram analisados os aspectos particulares que são tratados por códigos de normas nacionais e internacionais, quanto aos fatores que influenciam o cálculo e dimensionamento de lajes lisas, principalmente em função do fenômeno de punção da ligação laje-pilar que ocorre nesse tipo de elemento estrutural. A norma brasileira (NBR) 6118 (ABNT, 2023) classifica as lajes lisas em dois tipos, sendo maciças e cogumelos, esta última apresenta um reforço (capitel) na região da ligação laje-pilar, enquanto lajes lisas tradicionais são apoiadas diretamente sobre os pilares sem a presença de capitéis, ambas não contam com apoios secundários, vigas em sua composição estrutural, uma vez que o objetivo é permitir maior flexibilização arquitetônica, tempo de execução e redução do custo da obra. As lajes lisas apresentam uma grande problemática que é garantir a resistência ao fenômeno de punção. O fenômeno de punção faz com que as áreas de encontro com os pilares sofram uma sobrecarga, este por sua vez é ocasionado pelo peso próprio da laje e das cargas aplicadas sobre ela, podendo ocasionar de forma imprevisível a ruptura ou até mesmo um colapso progressivo. Nesse sentido, este trabalho teve como objetivo contribuir com o conhecimento de lajes do tipo bubbledeck e apresentar um levantamento bibliográfico atual através de estudos existentes de lajes lisas do tipo bubbledeck levando em consideração as análises e as recomendações normativas nacionais e internacionais quanto aos critérios de dimensionamento e execução de lajes lisas bubbledeck, de modo a contribuir com o conhecimento através de uma análise qualitativa sobre os atuais parâmetros praticados no meio profissional e científico, tendo em vista que atualmente a NBR 6118 (ABNT, 2023) não possui recomendações específicas que possam ser seguidas para dimensionamento de laje do tipo bubbledeck.

Ringing insects, Oncideres saga (Dalman, 1823) (Coleoptera: Cerambycidae), are a unique species found in the Americas, known for their tendency to ring branches and stems of several tree species, including Albizzia lebbeck Benth, often in afforestation contexts. The purpose of this study was to examine the presence of O. saga in A. lebbeck trees in Seropédica, analyzing the attacked branches, the number of postures, and the emergence holes. In November 2018, eight fallen branches were randomly selected based on girdling attributed to O. saga, along Estrada Dutra (BR-116). These branches were collected, duly identified, and sent to the Entomology Laboratory of the Department of Forest Products of the Forestry Institute of the Federal Rural University of Rio de Janeiro, where they were monitored until the emergence of adults to confirm the species. In these same branches, the postures and number of emergence holes of adults were evaluated nine months after collection. Of the eight branches examined with O. saga postures, adults emerged from six of them. The average number of ringed branches was 147 per sample. The average base-apex dimensions were recorded as 3.25 by 2.32, respectively. An average of 71 postures per branch were recorded. Pearson correlation analyses revealed a strong relationship between the size of the base and the apex of the branches, as well as between the apex and the occurrence of emergence holes. The results indicated a preference on the part of O. saga to deposit its postures on ringed branches with wider base and apex dimensions.

A doença de Parkinson (DP) é uma disfunção neurodegenerativa comum entre idosos, acometendo mais o sexo masculino do que o feminino. Seu diagnóstico tradicional é fundamentado em critérios clínicos, como aparecimento de bradicinesia somado a outros sintomas cardinais, tais como: tremor de repouso, rigidez ou instabilidade postural. O objetivo dessa revisão foi verificar a eficácia dos recursos fisioterapêuticos para a redução das quedas de pacientes com a doença de Parkinson: uma revisão de literatura. Trata de um estudo com revisões de literatura, sistemáticas e meta-análises na condição clínica geral, incapaci­dades, função motora e mental até a qualidade de vida dos pacientes com Doença de Parkinson, realizada no Laboratório de Estudos em Neurociências e Comportamento, na Faculdade de Educação Física e Fisioterapia da Universidade Federal do Amazonas/UFAM, consultando os bancos de dados eletrônico como o Scielo (Scientific Electronic Library Online) e a Biblioteca Virtual em Saúde (BVS), PubMED, Google Scholar e Cochrane. Os resultados da pesquisa demostraram que a utilização dos recursos fisioterapêuticos é expressiva na redução de quedas em pacientes com doença de Parkinson. Porém, a fisioterapia aquática foi a que se mostrou mais benéfica, devido à redução da sensibilidade à dor, promoção do relaxamento muscular pela diminuição da tensão, a redução dos espasmos musculares e prevenção a quedas.

Generation, types and impacts of biomedical waste during COVID-19: Indian context
Authors: Shefali
Published: October 2023

India's already-stressed waste disposal system has been strained by the COVID-19 outbreak. The challenge of managing biomedical Waste (BMW) in India has become more complicated in recent years, mainly due to the sudden emergence of COVID-19. As a methodology, a literature review was carried out with the help of Google Scholar, Research Gate, PubMed, and academic journal databases. Additionally, publications from numerous non-academic sources (such as news websites etc.) and current guidelines, such as those from the Ministry of Health and Family Welfare, Government of India, were also accessed. The review study identifies that PPE (Personal Protective Equipment) made up the majority of biomedical waste, followed by vaccine waste, during the peak of the COVID-19 vaccination campaign. The increase in PPEs such as face masks, aprons, face shields, gloves, goggles, and sanitizers, as well as other medical waste like bandages, plastic containers, syringes, testing kits, and tissues, has significantly changed the makeup of the BMW. This pandemic has hampered the proper management of solid waste, which has now surfaced as a major threat to developing countries. In this paper, biomedical waste management strategies followed in India and its disposal methods, cost-effective and environment-friendly methods to treat medical waste are also discussed.

Published: October 2023

There has been much concern about the rate at which industrial and household wastes are released into Creeks in Rivers State. The study examined the status of heavy metal pollutants (Cd, Cu, Zn, Cr, Pb, and Ni) in sediment and to determine the extent of damage caused by these human factors using the most recent pollution index and Sediment quality guidelines (SQGs). The research was carried out in four important creeks along the Delta River network in Rivers State, Nigeria (Okrika, Borokiri, Eagle Island, and Kaa). Triplicate sediment samples were collected at a depth of 0-20 cm and extracted with 20cm3 of aqua ragia (a 3:1 mixture of HCl and HNO3) and 10cm3 of 30% H2O2. The metal concentrations were measured using an Atomic Absorption Spectrophotometer (AAS). The concentrations of the heavy metals ranged from 11.147–18.919mg/kg, 11.918–14.379mg/kg, 8.321–11.691 mg/kg, 6.405–11.72mg/kg, and 5.718–12.125mg/kg, and 2.429-7.725mg/kg respectively and followed the sequence Zn > Pb > Cr > Ni >Cu > Cd. Geo-accumulation Index (Igeo) calculated was less than 0 i.e. uncontaminated for all metals except Pb in Borokiri Creek and Cd in all sampled creeks, showing moderate contamination. Eco-toxicological risk assessment (RI) indicated that the creeks were uncontaminated. Despite the low level of contamination, it is recommended that relevant authorities to regulate the indiscriminate dumping of domestic waste and untreated industrial effluents into the river to prevent the deterioration of the creeks
Toxic Metals Contamination of Cattle Hide Singed With Scrap Tyres

Published: October 2023

Processed cattle hide popularly known as “Ganda” in Nigeria is widely eaten as a substitute for meat but the commercial method of processing this food delicacy through singeing with scrap tyres has become a source of concern due to possible heavy metals contamination. This study evaluates the presence and levels of Cd, Cu, Fe, Pb, and Zn in the cattle hide samples obtained by using Atomic Absorption Spectrophotometry (AAS). The hide samples analyzed were obtained from seven states across the three geopolitical zones in northern Nigeria. Cd was not detected in most of the samples, notably from Niger, Zamfara, Adamawa and Plateau states, while concentrations of 0.0001±5.77E-5, 0.0005±4.71E-5, and 0.009±0.001 mg/kg detected from Kano, Kaduna, and Taraba, respectively, were lower than the maximum permissible level of 0.05 mg/kg set by the reference limits. Pb concentrations in all the samples analyzed were 1.080±0.072 to 1.760±0.160 mg/kg which surpassed the maximum permissible level of 0.1 mg/kg set by the reference limits, while other heavy metals were below the safe limits. The high levels of Pb introduced to the singed hide beyond the reference limits could be linked to the use of scrap tyres in the burning hairs of the hide, and it could be of great concern after consumption. In view of the above possible health implications that might arise, a detailed and proper health risk assessment technique needs to be employed in future research.

Egy alkalommal beszélgettem egy helyivel az országáról, és a kínai gasztronómiáról; említettem is neki, hogy finomak lennének ezek a levesek, ha nem lenne annyira vegyszer ízük a benne található zöldségeknek. Újdonsült ismerősöm nemhogy ellenkezett volna, inkább megnyugtatott, hogy az jó, ha ezt az ízt érzem, mert azt jelenti, hogy megfelelő éttermeket választottam, ahol a zöldségek kellőképpen tisztítva vannak.”
Félni vagy megijedni

„Jobb félni, mint megijedni. – Így hangzik a mondás. – Nem tudom, hogy igaz-e vagy sem, de üzenetét most más megvilágításba helyezném. Ha egy aforizmában igazságot vélünk felfedezni, akkor szinte magától beépül tudatfolyamatainkba. Ebből a mondásból következően, a félelemnek – ha mégoly csekélyke félelem is – szabad utat engedünk, hiszen az „felkészít” bennünket egy sokkal rosszabb, sokkolóbb állapotra, egy hirtelen élethelyzetre, és – talán igen, talán nem – valamilyen „támaszt” ad nekünk majd akkor.”
Matematikáról zen szemmel
Authors: Dobosy Antal
Published: October 2023

„Amennyire emlékszem középiskolai tanul­mányaimra, a matematika tárgy alatt leginkább megoldási módszereket tanultunk, melyek algebrai, geometriai, függvénytani, műszaki, vagy logikai feladatok megoldására vonatkoztak. Ha ezeket a módszereket jól tudtuk alkalmazni, akkor jó eredményeket értünk el „matematiká”-ból, ha nem, akkor rossz matekosoknak számítottunk. Azonban én úgy gondolom, hogy a közgondolkodással ellentétben matematika alatt nem ezt kellene értenünk. Az, amit az elemi- és középiskolában tanultunk, legjobb esetben a matematika eredményeinek alkalmazása a különböző területekre, azaz „alkalmazott matematika”, de ez tulajdonképpen egy másik tudomány. Ebben az írásban elsősorban az igazi matematikáról szeretnék írni, és arról, hogy milyen kapcsolata van a zen buddhizmusnak ehhez a tudományhoz, és arról, hogy mit tartok matematikának. Azt azonban be kell látnunk, hogy meglehetősen nehéz meghatározni, hogy mi a matematika, de azt is, hogy mi a zen buddhizmus, én mégis megpróbálok egy bizonyos szempontból kísérletet tenni erre.”

Based on the one-dimensional Gross-Pitaevskii equation (GPE) model, this work studies the formation of acoustic black holes in one-dimensional Bose Einstein condensate (BEC) in harmonic oscillator external potential, and extending the applicable scenarios of the GPE model for its specific application of simulating the formation conditions of acoustic black holes in one-dimensional systems. At the same time, We deepen the understanding of the analytical formula for determining the production conditions of acoustic black holes and the evolution formula of the radius of acoustic black holes.
Red Lines and Green Lights: Iran’s Balancing Policy in the South Caucasus
Authors: Gevorgyan Anna
Published: October 2023

After the Nagorno-Karabakh war in 2020, some Iranian political statements that support Armenia's security interests and ongoing "wars of words" between Iran and Azerbaijan led to the development of a theory in the international (including Armenian) scientific and analytical community that Iran has fundamentally altered its stance toward the South Caucasus states. This tendency had a substantial impact on Armenia’s public perception of Iran. As a vivid example, Iran is considered as Armenia's most significant security partner by 54% of questioned Armenians, according to a 2023 survey conducted by the International Republican Institute. This article explains Iran's broad geopolitical and security interests in the region and Iran’s balance of power approach via analyzing Iran-Azerbaijan relations using the theory of Cautious Realism. The article demonstrates that Iran's goals and interests in the region have not changed, and it continues its balancing policy and in relations with Azerbaijan uses tools of creating contra threats, as well as rapprochement.

Misuse of alcohol is rapidly becoming a public health issue among society's adolescents and adults. The harmful use of alcohol ranks among the top five risk factors for disease, disability and death throughout the world. This study was conducted to determine selected haematological parameters among chronic alcoholics in Ilorin. A total of 70 participants with chronic alcoholism and 30 control samples were randomly selected to determine the possible haematological risks of the social behaviour with majority of participants being within the age range 18-65 years. The haematological parameters PCV, haemoglobin, red blood cell, platelet, and total white blood cell counts were determined using the Sysmex XN-300 instrument. The count of reticulocytes was done manually. The mean value of the subject RBC was decreased (3.45±1.25) in comparison with (4.75±0.66) of non-alcoholics. The results demonstrate a decrease in the subject's mean reticulocyte value (0.724±0.820) compared to (2.12±0.81) of the control, but the difference was not statistically significant. This study found that abstaining from alcohol consumption has no significant influence on red blood cell markers, however extensive drinking had negative implications on the immune cells. As a result, a clinical history of drinking during haematological examinations, may be beneficial and advised especially if the findings show a decrease in the number of immune cells.
Análisis de las invectivas de Cicerón contra Antonio en las Filípicas
Authors: San Vicente Gonzalez de Aspuru José Ignacio
Published: October 2023

En las Filípicas, Cicerón utilizó una amplia variedad de invectivas para denigrar a Antonio, retratándolo como un individuo antisocial que encarnaba todas las taras morales y vicios. Lo describió como un enemigo del Estado y un tirano que aspiraba a la autocracia y buscaba eliminar a los boni, defensores de la República. Estos insultos se analizan a lo largo del artículo y se observa en ellos una inversión de las virtudes cardinales descritas por Cicerón. Según Cicerón, estas virtudes eran las cualidades que un estadista debía poseer, tal y como se detalla en su obra De Officiis, que escribió al mismo tiempo que pronunciaba las Filípicas.
Cicerón
Authors: San Vicente Gonzalez de Aspuru José Ignacio
Published: October 2023

Este artículo analiza la crisis de la República romana tardía, atribuida por los antiguos autores a la decadencia moral y a los vicios orientales y cómo Cicerón, defensor de las instituciones republicanas y de los boni, se enfrentó a los populares que buscaban reformas estructurales. Se destacan sus conflictos con Catilina, Clodio, Pisón y, especialmente, con Antonio. A lo largo de su carrera, Cicerón defendió su dignitas y argumentó que las virtudes cardinales propuestas por Platón y Panecio eran clave para alcanzar la verdadera gloria. En las Filípicas, atacó a Antonio y apoyó a Octaviano, aunque este último terminó traicionándolo. Estos discursos polarizaron la política romana, mostrando, según Bruto, la falta de visión política de Cicerón. Para defenderse de los ataques por su condena a los catilinarios y promover reformas estatales, Cicerón recurrió a la filosofía y defendió los principios platónicos y estoicos, abogando por la creencia en una providencia divina, la importancia de las virtudes cardinales, el uso de la razón y la superioridad del derecho natural de inspiración divina sobre la ley humana. También criticó a los epicúreos por su rechazo a la política, negación de la providencia divina y búsqueda del placer.

De Sensibus
Authors: Bodelón García Serafín
Published: October 2023

Este artículo trata de la teoría de la percepción en el De Sensibus de Teofrasto y en el De Rerum Natura de Lucrecio. Teofrasto realiza una exposición de las opiniones de Empédocles, Clidemo, Diógenes de Apolonia, Demócrito, Anaxágoras y Platón; pero también realiza una amplia crítica de las opiniones de dichos autores. Por otra parte, el poema de Lucrecio, en su libro cuarto, expone la teoría de los simulacra (D. R. N., TV, 50-360), donde se ocupa de la percepción, y más especialmente de la visión, pero también del problema del conocimiento.
Logos en la encrucijada de Alejandría
Authors: Pérez Herranz Fernando Miguel
Published: October 2023

Alrededor del «año cero» de la era cristiana se cruzaron en la cosmopolita ciudad de Alejandría (Alexandria ad Aegiptum) las ideas de Necesidad (ananké), de tradición griega, y de Dios Creador, de tradición hebrea. Aquí tuvo lugar lo que consideramos «la primera gran revolución filosófica» sobre el modelo socrático platónico y que configuró una matriz para desarrollar la filosofía que llega hasta nuestra época: no se comienza por la opinión (doxa), sino por el Libro, lugar de la revelación de Dios, que, a lo largo de los siglos, se irá sustituyendo por otro tipo de libros: constituciones, declaraciones de Derechos Humanos, historia, literatura patriótica, etc.; la riqueza desbordante del Libro se despliega a través del Logos en sus múltiples dimensiones (de especial relevancia es la figura de la Trinidad); un Logos mediador entre el Libro y la totalidad del Mundo y de las cosas.

Published: October 2023

As virtudes sociais são sem dúvida alguma fundamentais para preservar a harmonia e o desenvolvimento social, bem como a nossa autorrealização. Apesar de nunca ter escrito um tratado filosófico sobre este argumento, recorrendo à sua obra, Mediações, podem-se conhecer as virtudes sociais às quais o filósofo e imperador romano, Marco Aurélio, dá mais importância, a fim de garantir-se o bem-comum. Portanto, neste artigo, exponho estas virtudes sociais, mostrando, assim, como elas fundamentais para criar-se uma sociedade mais harmónica.
