A Continuous Energy Neutron Transport Monte Carlo Simulator Project: Decomposition of the Neutron Energy Spectrum by Target Nuclei Tagging
Authors: Chaves Barcellos Luiz Felipe Fracasso , Bodmann Bardo Ernst Josef , Bogado leite Sergio de Queiroz , De Vilhena Marco Túlio Menna Barreto
Published: February 2021

In this work the latest developments a Monte Carlo simulator with continuous energy is reported. This simulator makes use of a sum of three probability distributions to represent the neutron spectrum. Two distributions have known shape, but have varying population of neutrons in time, and these are the fission neutron spectrum and the Maxwell-Boltzmann distribution. The third distribution has an a priori unknown and possibly variable shape with time and is determined from parametrizations of Monte Carlo simulation. In this work the possible neutron-matter interactions are simulated with exception of the up-scattering of neutrons. In order to preserve the thermal spectrum, neutrons are selected stochastically as being part of the thermal population and have an energy attributed to them taken from a Maxwellian distribution, such an approximation is valid due to the fact that for fast neutrons up-scattering occurrence is irrelevant, being only appreciable at low energies. It is then shown how this procedure can emulate the up-scattering effect by the increase in the kinetic energy of the neutron population. Since the simulator uses tags to identify the reactions it is possible not only to plot the distributions by neutron energy, but also by the type of interaction with matter and with the identification of the target nuclei involved in the process.

Published: February 2021

As incrustações podem ser definidas como compostos químicos inorgânicos, inicialmente insolúveis, e que se precipitam se acumulam na parede interna de tubos, equipamentos de superfície e / ou partes de componentes envolvidos na produção e transporte de petróleo. Esses compostos, ao precipitarem, causam problemas na indústria do petróleo e consequentemente resultam em perdas na otimização do processo de extração. Apesar da importância e do impacto da precipitação desses compostos no âmbito tecnológico e econômico, ainda existe a dificuldade em determinar métodos que possibilitem a identificação e quantificação da escala em um estágio inicial. O uso da técnica de transmissão gama pode fornecer subsídios para um melhor entendimento da deposição desses compostos, tornando-o uma ferramenta adequada para a determinação não invasiva de sua deposição em dutos de transporte de petróleo. A geometria usada para a detecção de incrustações inclui um tubo de aço de 280 mm de diâmetro contendo escama de sulfureto de bário (BaSO4 ) variando de 5 a 60 mm, uma fonte de radiação gama com feixe divergente e como detector de cintilação NaI (Tl) 2x2 ”. O tamanho da abertura do feixe colimado foi avaliado (2 a 7 mm) para também quantificar o erro associado no cálculo da escala. O estudo foi realizado com simulação computacional, utilizando o código MCNP-X e validado por meio de equações analíticas que indicam a possibilidade de utilização deste estudo para este fim.

Authors: De Carvalho Bruno Natanael , Morais Mattar Patricia , Teixeira Pontes André
Published: February 2021

Radioactive materials are used for medical purposes, to avoid greenhouse gas effect in energy production plants, food and other products sterilization, research and sophisticated measurement technologies. Transport of radioactive material involves a range of actors each one having specific responsibilities for safety. Through Management System, consignors and carriers fulfil objective evidences that safety requirements are met in practice, while compliance assurance programs allow regulatory bodies and/or competent authorities to demonstrate to society that public, workers and environment are protected. According to IAEA, safety has to be achieved and maintained through an effective management system. This system should integrate all elements of management so that requirements for safety are established and applied consistently with other requirements, including those related to human performance, quality and security, and so that safety is not committed by other requirements or demands. CNEN, the Brazilian Regulatory Body for the safe transport of radioactive materials, adopt international standards to establish safety requirements deemed relevant for protection of health and minimization of danger to life and property, and to provide for the application of these standards. Seeking for continuous improvement, the adherence of the practices adopted by Transport Safety Unit (TSU) against the recommendations from the IAEA was assessed. This assessment led to the elaboration of proposals for improvement as well as the identification of good practices. The methodology used to perform this assessment was the SARIS methodology, developed by the IAEA. This paper will describe the most relevant findings of this study.

Published: February 2021

One of the greatest concerns when studying a nuclear reactor is the warranty of safe temperature limits all over the system at all times. The preservation of core structure along with the constraint of radioactive material into a controlled system are the main focus during the operation of a reactor. The purpose of this paper is to present the temperature distribution for a nominal channel of the AP1000 reactor developed by Westinghouse Co. during steady-state and transient operations. In the analysis, the system was subjected to normal operation conditions and then to blockages of the coolant flow. The time necessary to achieve a new safe stationary stage (when it was possible) was presented. The methodology applied in this analysis was based on a two-dimensional survey accomplished by the application of Finite Volume Method (FVM). A steady solution is obtained and compared with an analytical approach that disregards axial heat transport to determine its relevance. The results show the importance of considering axial heat transport in this type of study. A transient analysis shows the behavior of the system when submitted to coolant blockage at channel’s entrance. Three blockages were simulated (10%, 20% and 30%) and the results show that, for a nominal channel, the system can still be considerate safe (there’s no bubble formation until that point).
Monitoring System for an Experimental Facility Using GMDH Methodology
Authors: Pereira Iraci Martinez , Moraes Davi Almeida
Published: February 2021

This work presents a Monitoring System based on the GMDH - Group Method of Data Handling methodology applied in an Experimental Test Facility. GMDH is a combinatorial multi-layer algorithm in which a network of layers and nodes is generated using a number of inputs from the data stream being evaluated. The GMDH method is based on an underlying assumption that the data can be modeled by using an approximation of the Volterra Series or Kolmorgorov-Gabor polynomial. The Fault Test Experimental Facility was designed inspired in a PWR nuclear power plant and is composed by elements that correspond to the pressure vessel, steam generator, pumps of the primary and secondary reactor loops. The nuclear reactor core is represented by an electrical heater with different values of power. The experimental plant is fully instrumented with sensors and actuators. The Fault Test Experimental Facility can be operated to generate normal and faulty data. These failures can be added initially with small magnitude, and their magnitude being increasing gradually in a controlled way. The database will interface with the plant supervisory system SCADA (Supervisory Control and Data Acquisition) that provides the data through standard interface.
CHF prediction in rod bundles using round tube data
Authors: Veloso Maria Auxiliadora Fortini , Souza Wallen Ferreira De
Published: February 2021

The present work concerns the use of 1995 CHF table for uniformly heated round tubes, developed jointly by Canadian and Russian researchers, for the prediction of critical heat flux in rod bundles geometries. Comparisons between measured and calculated critical heat fluxes indicate that this table can be applied to rod bundles provided that a suitable correction factor is employed. The tolerance limits associated with the departure from nucleate boiling ratio (DNBR) are evaluated by using statistical analysis.
Curvilinear Coordinate System Used To Solve Tritium Dispersion In Complex Orographies.
Authors: Meneghetti André , Bodmann Bardo Ernst Josef , Vilhena Marco Tullio Menna De
Published: February 2021

In this contribution we present progress on research concerning dispersion of tritium around the Angra Nuclear Power Plant (Angra dos Reis, Rio de Janeiro state, Brazil). In particular, we are interested in studying how dispersion behaves in scenarios with complex orography. Our proposal is to transform a problem with curvilinear boundaries into an equivalent problem with plane parallel boundaries. We modify the coordinate system through a diffeomorph conformal transformation. Consequently, the operators of the dynamical equations change according to the additional terms from the affine connection. To define the transformation it is necessary to satisfy strong constraints, i.e., boundaries shall be “smooth”. Even with restrictions, our model can be implemented in several situations. A flat region is a particular case of a curvilinear domain and can be studied, where the height of the boundary layer above rivers, lakes, basins is typically smaller and thus implies a varying boundary layer height, for example. Thus, even in flat regions variations in the boundary layer occur, which characterizes a case of a curvilinear domain. There are several nuclear power plants worldwide, that are located in mountainous regions, as for example in Japan and Brazil.We present a simulation of tritium dispersion specifically in the area where the Angra 2 Nuclear Power Plant is located and where the relief is characterized by a considerable complexity. With the intention of showing that the methodology is consistent, we will consider only the variation of the relief.

Authors: Sharma Manoj
Published: February 2021

Recently COVID-19 has become a pandemic affecting almost all countries around the world.There is no cure or vaccine available for this disease.The only public health measures available for prevention are isolation, quarantine, and community-wide quarantine.Community-wide quarantine in the pandemic has forced people to stay indoors which has the potential to cause weight gain (similar to holiday weight gain) due to availability of food, staying at home, emotional distress, lack of physical activity, increased cortisol levels, and altered sleep. Fourth-generation theory-based approaches for preventing weight gain promoting home-based physical activity and healthy eating through online educational programs delivered through schools, worksites and social media online forums are recommended
Applications of the fourth-generation multi-theory model (MTM) of health behavior change toobesogenic behaviors in college students
Authors: Sharma Manoj
Published: February 2021

Obesity is a public health crisis that has reached pandemic proportions. It has multifactorial etiology and multiple negative physical and psychological consequences. Controlling the problem by altering obesogenic behaviors among college students is especially important because there is growing prevalence in this subgroup, there are long term effects for this subgroup, they are in formative years for obesogenic behaviors, and these behaviors are widely prevalent in this subgroup. The multi-theory model (MTM) of health behavior change is a new fourth-generation behavioral theory that has been applied to study obesogenic behaviors among college students. The purpose of this review was to examine the robustness and utility of MTM in designing efficacious and effective interventions to address obesogenic behaviors among US college students. A total of five studies published in MEDLINE, CINAHL, or ERIC met the inclusion criteria.The mean adjusted R2 for the initiation model based on the five studies was 0.38 (s.d. 0.15) and the mean adjusted R2 for the sustenance model was 0.34 (s.d. 0.14). The construct of behavioral confidence in the initiation model and the construct of emotional transformation in the sustenance model were significant in all five studies. MTM offers a feasible and practical framework for designing health promotion interventions for college students to address obesogenic behaviors

Chi square test was used to analyze the factors associated with BMI, WC and WHR cut-offs. The results showed a high prevalence of overweight and obesity in reproductive aged females residing in Rajbiraj. Hence, concerned agencies should launch appropriate programs to combat the factors.
Rotary dryer for thermo sensitive products
Authors: Gonzaga Diego A , de Ávila Mariane BR , Zotti Sperotto Naiara C , de C Melo Evandro
Published: February 2021

To achieve the desired drying objectives in thermal sensitive products, such as medicinal plants, the process chosen should happen under minimally controlled conditions, such as, uniformity of temperature and air velocity, minimizing heat loss and with energy viability and efficiency. If possible, the process must occur using equipment with industrial implementation where the evaporation rate can be controlled. The intermittent drying process, which consist of cycles of exposure of the material to heated air (period of effective drying) and tempering (period of no exposure to heated air), is a great option to preserve the product’s quality during the drying process. We propose a new configuration of rotary dryer intended for intermittent drying; observing the configurations of widely applied rotary dryers, the relationship between angular velocity, period and frequency of rotation and laboratory experiments of manufacturing process in intermittent drying. The proposed dryer is efficient for the application of intermittent drying in products with high thermal sensitivity, such as medicinal plants. Making possible uniformity of temperature and air velocity distribution, minimizing heat loss and with energy viability and efficiency, guarantying the product quality.

Introduction: Children with microcephaly as a result of fetal exposure to the Zika virus (ZIKV) may experience brain changes, neurological abnormalities, bone and craniofacial deformities. Objective: The objective of this study was to describe oral problems and oral health habits involving children in early childhood with microcephaly associated with fetal exposure to ZIKV. Methodology: A cross-sectional study was carried out on a sample of children with microcephaly, exposed to ZIKV during the pregnancy, attended at the Neuropediatrics outpatient clinic of a reference center in Salvador-BA. Clinical examination of oral conditions and interviews with mothers/ guardians were performed to obtain sociodemographic data and lifestyle habits. A descriptive analysis of the variables and exploratory analysis of factors associated with defects in enamel development (DDE) were done using Pearson's chi square and a significance level of 5%. Results: 74 children participated in the study and a higher frequency of the following oral conditions was observed: delayed eruption chronology (100%), dental biofilm (55.88%) and enamel defects (DDE) (22.06%). Bohn nodules (6.85%), micro dents (2.70%) and ectopically positioned dental elements (1.35%) were less frequent. Only one of them showed incipient caries lesion (1.47%). The occurrence of DDE was more frequent among those with ogival palate, normal weight at birth and who did not have an eruptive delay (p <0.05). In oral habits, 52.70% used a pacifier, 50% feeding at night, 66.22% used sugar and 52.24% brushed teeth before bed. Conclusion: Monitoring oral health conditions is necessary to minimize oral health problems in these children.

Authors: Matthew Anyanwu
Published: February 2021

Background:/Aims: The use of antiretroviral drugs (ARVs) in pregnancy has shown remarkable improvement in immune status and have revolutionized the approach of care to people living with HIV (PLHIV). Some adverse pregnancy conditions have been reported which may depend on type of regimen, time and duration of use. The use of ARVs in pregnancy have been dynamic and transition from one regimen to the other have setting and country based variations. Therefore, knowing the impact of ARVs in pregnancy among PLHIV in our settings deserve evidence based information. Methods: Pregnant women attending antenatal clinic at the hospital were prospectively recruited and followed up. HIV positive mothers were recruited irrespective of gestation age. At the time of delivery, obstetric and neonatal characteristics were entered into computer database. Mothers and their children were followed until 6 weeks postpartum. The data was analyzed with Epi-info version 7.1.5. Chi square at significant level of 0.05 and confidence level of 95% was used to determine significance. Results: A total of 55 HIV positive mothers were in the study. The age range was between 18 to 45 years and parity was 0 to 8. The mean birth weight and gestation age at delivery was 2.92kg (SD 0.556) and 36 weeks (SD 2.8 weeks) respectively. The absolute CD4 count of 500cells/mm3 and above (43.3%) was associated with no low birth weight. The mean glycaemic results were within normal range, 4.02-4.75 and 5.00-6.79 Mmol/l pre and post prandial respectively. Conclusion: Low birth weight was not associated with HAART in pregnancy and good immune condition was not associated with low birth weight. There was no association of protease inhibitors and gestational diabetes mellitus.
Ethical issues when non-paternity is an incidental finding
Authors: G Howe Edmund
Published: February 2021

Biological non-paternity is sometimes discovered incidentally as a result of genetic testing for other medical purposes. Providers may then struggle when deciding what they should do. This question is profoundly important because providers’ disclosing this information may be most destructive to families, and especially to children. This piece will review major concerns likely to arise in these cases. It will also present several different approaches care providers have taken in an attempt to resolve this dilemma both before and after this finding is discerned. The author will suggest that a framework not commonly applied to such questions, the Ethics of Care, may be particularly helpful to providers facing this question
“Ought” as a speech-act"
Authors: Demirel  Erturk
Published: February 2021

Justification of moral judgments subsists as one of the recalcitrant question marks of philosophy; are they somehow unlike the so-called factual judgments; do they have a cognitive value; what, if anything, could possibly justify them despite the assumed chasm between facts on one hand and values, on the other? I believe it is, at least in the early modern era, the Humean legacy in ethics to have eyes for the naturalistic fallacy and sometimes despair over the seemingly inexplicable bridge between “Is” and “Ought.” I shall investigate whether Nietzsche has a solution of his own to the problem and if he has, whether it is indeed a Humean one. In what follows I shall try to produce a brief exegetical reading of Nietzsche’s main texts to reflect on the parallels between moral critique of Nietzsche and Hume’s epistemic understanding of moral judgments. With this aim, I shall connect Hume’s insights with Nietzsche’s related remarks, dwelling on three books by Nietzsche mainly: Human, All Too Human, Beyond Good and Evil, and Will to Power. Nietzsche avers that causality of free will is no more than an associative feeling to connect an idea with another. In sum, the inferential guide that links “Is” with “Ought” is based on a social need to hold individuals morally responsible on the basis of their behaviour. Therefore the link traditionally provided between the I-sentences and the O-sentences is not a metaphysically necessary one, as implied by the causality of free will, but an outcome of societal forces that attribute free will to human beings.In other words, the relation between the I-sentences and the O-sentences is not metaphysically necessary according to the transcendental law of morality, but socio-political laws that changes empirical beings into moral beings. Furthermore, he claims that there are diverse canons of morality that apply to diverse characters.To put it into modern jargon, the moral judgments and arguments can be seen as performative statements, since they do not express the relations among facts which are independently and intrinsically moral, but acts on and constitute them as moral and the persons those facts are attributed to morally responsible.I argue that the O-sentences comprise a sub-set of speech-acts. They do not only express moral facts, but also constitute them as moral.
Development of a modified open set sentence test for assessment of speech perception skills in Hindi preschool children
Authors: Nandurkar Aparna , Rajani Yaashna
Published: February 2021

Introduction: Clinical assessment of speech perception skills is very important for several reasons. However, it is routinely assessed in older children and adults but not in very young children mainly due to lack of appropriate tools, especially in Indian languages. Considering the limitations of closed-set and open-set tests for young children modified open set test would be appropriate. Aim: To develop a modified open set sentence test in Hindi based on the Mr. Potato Head Test framework using appropriate toy and sentence material and employ the developed test to assess children with normal hearing in the age range of 18 to 48 months. Method: Two sentence lists with ten sentences each and one practice list with five sentences were developed. The test was recorded in a professional studio by a sound engineer and sentences were calibrated using the Bruel & Kjaer-Type-2250 sound level meter (SLM) so that the test could be administered via speakers using a laptop. The test was administered in a quiet room, directly through a laptop connected to speakers on 200 Hindi speaking children with normal motor and speech developmental milestones and bilateral pass result on OAE screening. Results and discussion: There was a significant difference in the scores between the 5 age groups of children with normal hearing. There was an increase in scores as age increased, thus indicating improved performance with increasing age. There was also no significant difference in the performance on List 1 and List 2 for all age groups indicating that the two lists were equivalent. Item reliability was also observed to be high. Conclusion: The developed Modified Open Set Sentence Test can be successfully used to assess speech perception skills in young children with normal hearing. This test has a potential to be a useful clinical tool when used as a part of a test battery and also play a role in monitoring the progress of an intervention program.
Chondro-osseous respiratory epithelial adenomatoid hamartoma of the nasal cavity (COREAH): A case report
Authors: Elias MD Nikolopoulos
Published: February 2021

Objective: Determine the efficacy of the anterior skull base reconstruction in adult patients with intranasal meningoceles and meningoencephaloceles treated by endoscopic endonasal approach. Study design: Retrospective observational study of adult patients admitted to a tertiary hospital. Materials and methods: Intranasal meningocele was defined as a protrusion of meninges through a defect in the skull base forming a cyst filled with cerebrospinal fluid in the nasal cavity or paranasal sinuses. If the cyst had brain tissue it was called meningoencephalocele. The electronic clinical records of patients admitted with suspected of intranasal MC or MEC between January 2010 and December 2018 were reviewed. All patients treated by endoscopic endonasal approach were included. We excluded those cases with anterior skull base previous surgeries (iatrogenic or following tumoral resections), reconstruction with external surgical approaches and those who were less than 18 years old. Results: Intranasal MC was the most frequent lesion (6/5) and there was one patient with MEC (1/6). 5 cases were idiopathic and one patient had history of transnasal surgery. A total of 83,3% of the cases were primary surgeries and one patient had 3 prior MC surgeries. Only in four of them (66,6%) the lesion location was detected by at least one of the studies (CT, MRI and/or endoscopy). We performed a multilayer closure technique in all patients. During the immediate postoperative period, one patient had acute meningitis. One patient had a CSF leak recurrence 4 months after surgery. The success rate of the reconstructions performed by endonasal approach was 83.33% (5/6). The average follow-up of the patients was 15 months. Conclusion: The effectiveness of the anterior skull base reconstruction in adult patients with meningoceles and meningoencephaloceles performed by endoscopic endonasal approach in our series was 83.33% (5/6). This procedure is currently the gold standard due to its high efficacy and low morbidity. According to current studies, it is recommended to perform the reconstruction with a multilayer technique.

Lithium-based vertically aligned nanocomposites for three-dimensional solid-state batteries
Authors: Cunha Daniel M. , Huijben Mark
Published: February 2021

Planar two-dimensional (2D) solid-state lithium-ion batteries exhibit an undesirable energy versus power balance, which can be dramatically improved by the application of three-dimensional (3D) geometries. Current ceramics-based nanocomposites exhibit limited control of the distribution and orientation of the nanoparticles within the matrix material. However, the tailoring of functionalities by the strong coupling between the two phases and their interfaces, present in epitaxial 3D vertically aligned nanocomposites (VANs), show promising advantages over the conventional 2D planar multilayers. Although a range of epitaxial VANs have been studied in the last decade, lithium-based VANs toward battery applications have remained mostly unexplored. Interestingly, two recent studies by Qi et al. and Cunha et al. demonstrate the unique potential of lithium-based VANs toward the realization of 3D solid-state batteries with enhanced energy storage performance. In this article, we will discuss these promising results as an enhanced current collector within the cathode or as an integrated solid-state cathode-electrolyte composite. Furthermore, we will describe different design configurations that can be applied to realize self-assembled VAN-based complete 3D battery devices.

ABSTRACT Objective: to assess the results of a training program focused on the well-being of elderly individuals from the perspective of users, through the opinion on the program impact on their active aging. Methods: a qualitative research, carried out from an intentional sample, consisting of 10 elderly women. Interview conducted by focus group, recorded and transcribed, which constituted the corpus of analysis. Lexical analysis of textual data was performed using the Alceste software. Results: from the analysis, three classes emerged: 1) Health-Activity; 2) Activity-Expectation; 3) Mind-Body Unit. The Activity-Expectation class stands out. Conclusions: the research revealed that elderly individuals consider it important to have expectation, which results in satisfaction and involvement with life as well as the ability to remain active in a perspective of mind-body unit. Future projects should focus on enhancing mental and physical functions to promote active and healthy aging.
HEIDEGGER E PAULO: A MODALIDADE DE VIDA AUTÊNTICA ( WIE ) E A TEMPORALIDADE ESCATOLÓGICA NA APROPRIAÇÃO FENOMENOLÓGICA DA PROCLAMAÇÃO DA παρoυσíα
Authors: Santos Bento Silva
Published: February 2021

RESUMO O artigo trata da apropriação fenomenológica das epístolas aos Tessalonicenses levada a termo por Martin Heidegger em sua prelação do semestre de inverno de 1920-1921 intitulada “Introdução à Fenomenologia da Religião” (WS), quando era assistente de Edmund Husserl na Universidade de Freiburg (1919-1923). A preleção foi publicada pela primeira vez no quadro da Edição Integral (Gesamtausgabe = GA) das obras de Heidegger em 1995. No artigo considerarei especialmente a noção de temporalidade escatológica a partir da análise do fenômeno cristão da παρoυσíα fora do contexto do sercrente e de sua consequente fundamentação teológica. Portanto, a proposta do presente estudo sobre o jovem Heidegger consistirá, em primeiro lugar, no “status quaestionis” da pesquisa sobre a referida preleção acadêmica e sua relação com o Denkweg de Heidegger. Em segundo lugar, destacarei a peculiaridade da leitura das epístolas de Paulo no contexto de uma abordagem fenomenológica a partir do conceito de “pré-compreensão” (Vorverständnis) no sentido de que há um sentido a ser procurado em um fenômeno sem ainda determiná-lo teoricamente. Esta categoria metodológica indica um horizonte para o qual é preciso avançar realizando uma metamorfose do si (Selbst) (e não simplesmente preenchendo a intuição). Em terceiro lugar, examinarei o §26 da segunda parte da mesma preleção acadêmica que versa sobre a “expectativa da parusia” (Die Erwartung der Parusie) no Cristianismo das Origens para explicitar especialmente as conexões entre historicidade e modalidade da vida autenticamente vivida (o como [Wie] da existência), bem como a estrutura da temporalidade vivida pelo Cristianismo das origens: “a experiência fática da vida é histórica. A religiosidade cristã vive a temporalidade como tal”.
TELEOLOGY AND NOUS IN PLOTINUS’S ENNEAD VI.7
Authors: Andrade Bernardo Portilho
Published: February 2021

RESUMO Neste artigo, argumento que a crítica de Plotino contra a deliberação divina na Enéada VI.7 não busca banir toda teleologia de sua filosofia da natureza. Ao contrário, sua crítica procura adequar a teleologia ao seu sistema metafísico de forma a torná-la consistente com os princípios básicos que regem o universo inteligível. Nesse sentido, Plotino não propõe banir das explicações naturais toda referência às noções de utilidade ou benefício, mas busca conciliar essas noções com uma ontologia na qual o Intelecto tem sempre prioridade sobre o mundo sensível. Para esse fim, Plotino introduz, em primeiro lugar, o que chamo de uma teleologia vertical, segundo a qual as diferentes espécies animais criam as condições necessárias para a manutenção de formas mais elevadas de vida inteligível, como genera. Em segundo lugar, Plotino introduz uma teleologia horizontal, por meio da qual os vários órgãos animais fornecem um coeficiente mínimo de conteúdo noético para cada espécie em seu respectivo nível ontológico. Desse modo, Plotino esboça uma teleologia propriamente ‘noética’ na Enéada VI.7.
ALTRUISM AND MORAL ENHANCEMENT
Authors: Nahra Cinara
Published: February 2021

ABSTRACT In this article I will be discussing what altruism is, distinguishing altruistic motivations (pure and impure) and altruistic behaviour (soft and robust). Pure altruism is when the motivation to benefit another is exclusively to increase the other's welfare, and impure altruism is when the motivation to benefit another is solely to increase your own wellbeing, or includes on some level, increasing your own welfare. Soft altruism is helping behaviour and robust altruism is improving the welfare of another individual at the expense of the altruist. Having made these distinctions I move on to show that altruism is a requirement of morality. I argue that the three main principles of morality (categorical imperative, golden rule and the greatest happiness principle) are not only compatible with, but also recommend soft altruism. Finally I argue that the probability of people continuing to practise altruistic acts is higher when we are purely motivated, and if that is the case not only classic moral enhancement but also biotechnological moral enhancement can have a role in bringing people over to the altruistic side, stimulating their ‘other regarding ’ motivations, thus contributing to spreading altruistic behaviour and morality throughout the world.
METAFÍSICA TEÓRICA E METAFÍSICA PRÁTICA EM SCHOPENHAUER À LUZ DA INFLUÊNCIA DE FRANCIS BACON
Authors: Silva Luan Corrêa da
Published: February 2021

RESUMO O presente artigo tem por objetivo caracterizar a “metafísica prática ” em Schopenhauer. Segundo essa caracterização, a metafísica prática corresponde ao correlato prático da “metafísica teórica” e, desse modo, ao correlato empírico do discurso filosófico. Para Schopenhauer, isto equivale a afirmar a possibilidade de comprovação, via experiencia, da tese metafísica fundante de “O mundo como vontade e como representação”, a saber, da identidade metafísica da vontade subjacente aoplano da multiplicidade aparente. Por funcionar como uma espécie de prova empírica desta tese metafísica, a metafísica prática é também Experimentalmetaphysik, isto é, “metafísica experimental”.
CHANCE (τύχη), FATE (εἱµαρµένη), 'WHATDEPENDS ON US' (τὸ ἐφ' ἡµῖν) AND PROVIDENCE (πρόνοια) IN PLUTARCH'S QUAESTIONES CONVIVALES
Authors: Lopes Rodolfo
Published: February 2021

ABSTRACT One of the many philosophical issues discussed throughout Plutarch's Quaestiones convivales (QC) has to do with the origin and inner structure of the universe, i.e., cosmological discussions. It would be impossible to discuss in detail every passage of the treatise that deals with cosmological issues. Therefore, I chose to limit my analysis to the concepts of chance (τύχη), fate (εἱμαρμένη), ‘what depends on us ’ (τὸ ἐφ' ἡμῖν), and providence (πρóνoια). My purpose is to explain these concepts in the QC and to extract from them a cosmological doctrine.
Awe: Efeitos Cognitivos, Emocionais e Motivacionais do Deslumbramento num Contexto Experimental
Authors: Ferreira Maria Eduarda , Mendes Paulo , Sardenberg Beatriz , Pinho Marina Martorelli
Published: February 2021

Resumo A relativamente inexplorada emoção de awe, que pode ser descrita em português como a sensação de deslumbramento e transcendência perante a percepção subjetiva de grandiosidade, vem sendo experimentalmente associada a efeitos positivos de natureza diversa. Nos artigos encontrados para inclusão nesta revisão bibliográfica, foram relatados um aumento da pró-socialidade e de sentimentos afiliativos, melhoras no humor e na satisfação pessoal, e modificações na concepção dos participantes acerca do tempo, levando a uma redução da impaciência e incentivando a busca de experiências de crescimento pessoal em lugar de recompensas imediatas. Esse sentimento também pareceu encorajar o senso crítico com relação a tentativas de convencimento, além de promover a espiritualidade e a identificação de propósito na realidade.
Recaída de Variabilidade Operante com a Combinação dos Procedimentos de Renovação, Restabelecimento e Ressurgência
Authors: Chiaparini Gabriela , Abreu-Rodrigues Josele
Published: February 2021

Resumo O reaparecimento de variabilidade comportamental previamente extinta (i.e., recaída) foi investigado por meio dos modelos experimentais de renovação, restabelecimento e ressurgência. Na Fase de Treino (contexto A), ao serem expostos ao esquema múltiplo Lag 10 Acoplado, ratos apresentaram níveis similares de variabilidade nos dois componentes. Na Fase de Eliminação (contexto B), o esquema múltiplo Repetição Repetição promoveu a extinção da variabilidade. Na Fase de Teste (contexto A), com a suspensão da contingência de repetição e a liberação de reforços independentes, a variabilidade reapareceu no componente “Lag 10”, anteriormente correlacionado com reforçamento da variação, mas não no componente “Acoplado”. Esse resultado sugere que a variabilidade observada no teste de recaída corresponde à variabilidade operante, e não à variabilidade induzida pela extinção.
