Published: August 2024

In the present study, an on-demand solar combined cooling, heating, and power (CCHP) system with parabolic trough collector (PTC) and solid-state thermal energy storage (TES) is investigated, which will be demonstrated on-site in 2024 at the Administration Building of the Lavrio Technological and Cultural Park (LTCP) in Attica, Greece, covering the energy needs of the building in form of heating and electricity in winter and cooling during summer. The system is based on a combined Organic Rankine Cycle and an Ejector Cooling Cycle (ORC-ECC), which is modeled and simulated in a steady-state manner while the PTC and TES systems are modeled dynamically, i.e., they are influenced by the thermal inertia of the components, the variable weather conditions of the location, and the defined operating strategies. The ORC-ECC simulation results show an efficiency of up to 14.20 % for the ORC system and a Coefficient of Performance (COP) of 0.10 for the ECC system under defined conditions. The dynamic simulations for the specified operating strategies indicate that on typical sunny days up to 100 % of the consumers' electricity consumption can be covered by the system.
Variation in Reflected Beam Shape and Pointing Accuracy Over Time and Heliostat Field Position

Published: August 2024

Heliostats are typically constructed with fixed mirror shapes, which they move to varying angles to reflect sunlight onto a receiver. While heliostat facet curvatures and canting angles are selected to maximize a chosen performance criterion, these fixed shapes inevitably cannot maintain focus throughout widely varying solar incidence angles. Further, heliostat pointing accuracy generally exhibits error due to manufacturing and installation imperfections. In this paper we present a systematic study of how reflected beam shape and pointing accuracy vary with heliostat position, time of day, and time of year. We selected nine heliostats spanning the Sandia National Laboratories National Solar Thermal Test Facility (NSTTF) heliostat field, and measured their beam shape and required pointing corrections throughout the day, for six key dates spanning a solar year. We also present ray tracing analysis to aid understanding of the observed effects. The resulting data provide insight into the nature and magnitude of heliostat focus loss at various times, and clarify the nature of the problem faced when attempting to maximize heliostat field performance, especially for high-temperature industrial applications. We conclude that fixed heliostat fields canted with an off-axis strategy will lose significant performance away from the solar noon hour to which they are tuned, and that aim point corrections can vary widely, both between independent heliostats and over time for a given heiostat. This implies that multiple measurements of each heliostat are required to determine calibration pointing corrections.

Botulism in wild birds and association with water quality at the Pelican Harbor Seabird Station, Miami, Florida.
Authors: Guzman-Barragan Blanca Lisseth 
Published: August 2024

Botulism avian is a disease of great importance in public and animal health, being the most common cause of death in wild birds worldwide, mainly affecting aquatic and shore birds. In October 2022, a significant increase in clinical cases of avian botulism was identified at the Pelican Harbor Seabird Station, in Miami, Florida. The objective of the present study was to analyze report cases of avian botulism and its association with water quality. Between June and October, 130 animals with a presumptive clinical diagnosis of botulism were received at the wildlife center. The clinical histories were obtained, which were systematized in a database to perform descriptive analyses and estimate prevalence, lethality, and mortality indicators. The association of the presence of botulism and water quality was carried out using Spearman coefficients for non-parametric data and risk analysis with calculation of X 2 and OR. Calculations were performed in SPSS software. The results showed that the prevalence of avian botulism was 20.7% in the period, with the mortality varying between 9% to 19% and lethality between 54% to 90%. The most affected species were Eudocimus albus and Leucophaeus atricilla, the main clinical signs observed were limb paralysis in 92% of the cases. An association was found bewteen a disease and combined quality variables and nitrogen. A possible association between the disease and water is identified, however, more studies are needed to determine the influence of water and measures to preserve the fauna.

Pistacia lentiscus oil is used in traditional medicine. The purpose of the present study was to determine if the Pisatcia lentiscus oil is of any interest for human nutrition and pharmaceutical industry. For this purpose, the physico-chemical properties of the oils of P. lentiscusfrom 12 localities of Northern Algeria were studied and compared as well as their compositions in free fatty acids, total polyphenols, flavonoids and chlorophylls.The agar well diffusion method and broth microdilution assay method are used to evaluate the antimicrobialand the antifungal activity of the 12 oils against 8 referenced microorganisms. Minimum inhibitory concentration (MIC) and Minimum Bactericidal Concentration (MBC)were calculated. Results showed that Pistacia lentiscusoilhas similar physico-chemical properties as virgin olive oil with an acid index around :3,5 ; a peroxide index around : 6, a saponification index between 179 and 200mg/g oil. And these oils were rich in chlorophyll, flavonoids and total polyphenols. Micrococcus luteus and Staphylococcus aureus have a sensibility against Pistacia lentiscus oils. An antibacterial effect was noted against Micrococcus luteus with inhibition zone diameters reaching18,5 mm. The Minimum inhibitory concentration attains 2,5mg/mL for Aspergillus niger, in Bouira locality. Statistical analysis could not differenciate groups according to the origin. Pistacia lentiscus oil is rich in unsaturated fatty acids. This oil can be used for human nutrition, agro-industrial processing and for pharmaceutical industry.
Um feminismo afro-latino-americano na Argentina? Antirracismo e abolicionismo penal nas mobilizações feministas (1980-2022)

Este texto apresenta os resultados de pesquisa realizada no AfroCuritiba, projeto de extensão que tensiona a invisibilização das presenças negras locais. Desenvolvida em concomitância com iniciações científicas nos Estudos de Gênero, a investigação foi motivada por um interesse em cartografar quais ativismos foram desenvolvidos em resposta ao racismo da sociedade argentina, interpelando especialmente as reações feministas, em suas limitações e mudanças históricas. Dialogo com referenciais dos feminismos negro e anti-colonial, mobilizando-os para a análise de práticas feministas articuladas de 1980 ao momento. Utilizo como arquivos artigos publicados por ativistas argentinas, como Josefina Fernández, Patricia Gómez e Sandra Hoyos, e brasileiras, com Lélia González. Desse modo, indico uma postura feminista de silenciamento racial nos anos 1980, que acompanha a narrativa normativa de uma Argentina branca, a qual, mediante disputas dos feminismos negros a nível regional, tem se comprometido com lutas transversais pela abolição dos aparatos subjetivos e institucionais de violência racial. -- Resumen: Este texto presenta los resultados de una investigación realizada en AfroCuritiba, un proyecto de extensión que enfatiza la invisibilización de las presencias negras locales.

The Promises of Responsible Open Science: Is Institutionalization of Openness and Mutual Responsiveness Enough?
Authors: Edwards-Schachter Mónica 
Published: August 2024

Von Schomberg offers a compelling examination of key open science principles and their potential role in fostering responsible research and innovation (RRI). Utilizing Merton's Ethos of Science framework, the paper constructs a series of arguments supporting a central thesis: “the transition towards open science is vital to facilitate RRI.” This transition necessitates significant institutional reforms within the scientific community and adjustments to incentive structures that promote the adoption of open and mutually responsive practices.The manuscript reframes the discourse surrounding responsibility and responsiveness in light of the evolving landscape of open science, shifting the focus from normative commitments to actionable frameworks in research and open science practices. Overall, the position paper strives to bridge the gap between idealised models of scientific communities based on RRI principles and the reality of actual scientific endeavour (Anderson et al., 2007; Politi, 2021, 2024).However, it is important to acknowledge certain omissions that could enrich the analysis. Firstly, a more comprehensive examination of the profound crisis facing science amidst the increasing marketisation and commodification of academia and research would provide valuable context beyond discussions of system failures related to productivity and reproducibility. Secondly, a more nuanced and critical approach to conceptualising open science would enrich the discussion, considering its multifaceted nature and potential pitfalls. Thirdly, the validity of the Mertonian framework and its selective analysis of values, particularly its exclusive focus on the norm of communism. Lastly, a deeper exploration of the challenges and promises inherent in the pursuit of responsible Open Science within ongoing institutional processes.

Published: August 2024

Este estudo buscou analisar a ginástica acrobática entre 1973 a 1974, na Olimpíada Infantojuvenil de Ponta Grossa (Olijup), PR. A partir deste recorte de pesquisa, buscamos compreender quais foram os aprendizados inculcados por meio da inserção da ginástica acrobática na Olijup. Trata-se de uma pesquisa documental, bibliográfica e exploratória. Para isso, utilizamos imagens fotográficas, ata s e regulamento da Olijup, além de recortes de jornal, fontes que foram mediadas pelas reflexões de autores como Dubois, Dussel e Pollack. Por meio dessas fontes, foi possível perceber a socialização esportiva entre professores, estudantes e comunidade escolar, bem como o comprometimento, o disciplinamento e o compromisso dos atletas juvenis. Notamos a mitificação dos atletas escolares, ao compartilharem as técnicas da ginástica na Olijup e fora dela, e observamos a importância dessa manifestação na constituição da olimpíada e no aprendizado esportivo.
Virginia e Francesca, ela e eu: lugares comuns
Authors: Filizola Marcela 
Published: August 2024

O presente artigo se propõe a pensar e questionar categorias de gênero a partir dos ensaios de Virginia Woolf (1882-1941) e do trabalho fotográfico de Francesca Woodman (1958-1981). Ao refletir acerca de noções de corpo e sua porosidade na relação com os movimentos do pensamento, busca-se criar uma conversa com teóricas feministas, como Judith Butler, Adriana Cavarero, Rosi Braidotti, entre outras, para investigar novas possibilidades éticas nos momentos de encontro com o mundo. Por fim, o trabalho explora alguns aspectos do romance To the Lighthouse (1927), de Woolf, para considerar a relação entre humanos e não humanos, de modo a indagar a respeito da linguagem em conjunto com construções de subjetividade.
NOTABILIA ALCOBACENSES: UM TRATADO MEDIEVAL PORTUGUÊS
Authors: Beccari Alessandro 
Published: August 2024

Este artigo tem como intuito oferecer uma apresentação inicial de um texto oriundo da Idade Média portuguesa, em que se encontram teorizações a respeito da sintaxe latina em análises contrastivas com exemplos do português arcaico. Escrito no Mosteiro de Alcobaça, Notabilia Alcobacenses constituem um texto didático que apresenta características dos tratados medievais, a saber, seu discurso é pautado por quaestiones disputatae de pontos gramaticais, em que o autor, Juan Rodríguez de Caracena (fl. ca. 1400-1427), um monge cisterciense espanhol, cita amiúde autoridades reconhecidas no clima de opinião do Baixo Medievo: Petrus Helias (ca. 1100 - post 1166), Robert Kilwardby (1215-1279) e Alexandre de Villa Dei (ca. 1175-1240/1250). Assim, tem-se como objetivo uma apresentação do fenômeno da gramática latina em Portugal (FERNANDES, 2017a, 2017b, 2015, 2014, 2012) como parte de um Zeitgeist geral (KOERNER, 2014), isto é, do Escolasticismo, e de sua expressão local como produto da escola do claustro alcobacense, estando o manuscrito disponível ao longo de séculos na biblioteca do Mosteiro (ASSUNÇÃO; SILVA, 2009). Quer-se também discutir alguns dos tópicos gramaticais presentes no manuscrito, os quais dão testemunho do pertencimento dos Notabilia Alcobacenses à vertente meridional da gramática latina do período, também conhecida como grammatica positiva do sul da Europa (LAW, 2003; PERCIVAL, 1994). Nessa discussão, utilizam-se excertos do manuscrito, traduzidos pelo autor, originalmente transcritos por Augusto, Kemmler e Fernandes (2012), pesquisadores do Centro de Estudos em Letras (CEL) da Universidade de Trás-os-Montes e Alto Douro (UTAD), Portugal.

In terms of energy production and consumption, the modern world's needs have become more and more challenging. Electrical energy is required to power most of all current “gadgets”, as well as, large industrial equipment, and more recently, our cars, which are expected to become all-electric in the not so far future. Once electrical energy (actually any kind of energy) can not be created or destroyed, it must be converted from other forms of energy.Our economy is still dependent on fossil energy sources like coal, petroleum and gas, which may be directly used to heat our homes and keep our cars running, but also to be converted into electrical energy. The drop-back of these resources is that they are highly pollutant and a worldwide movement is trying to reduce its use. Many bio alternatives have been proposed to replace these energy sources with a certain level of success. They are renewable and may help to reduce the greenhouse gas emission problem, however, alone, they will not solve the problem. In Brazil, most of the electrical energy comes from hydroelectric plants which are clean, renewable and reliable sources, however produces some undesired environmental impacts, most of them during the power plant construction. There is also a limited amount of this kind of energy that can be exploited. In parallel, we have the clean and renewable wind and solar sources. Both extraction technologies have already reached a higher maturity level and their use has been increasing in recent years. There is a great potential for large generation plants and also for small units to be installed in domestic homes or small consumption centers. For sure, there are other energy sources that could be included in the discussion.Any emerging country, like Brazil, needs to increase its infrastructure and reach a higher level of technological development. Among many factors, energy is one of the most important ones. A key issue with the energy production is its cost, and to reduce production costs, technological advances are needed. A promising emerging country can not rely only on foreign knowledge (technology) to build its infrastructure. Moreover, sustainable development can only be achieved when technological advances are promoted by its universities and research groups in a close collaboration with the industrial sector. For every energy type above discussed, even those with a higher level of development, there is still room for new discoveries, new applications and improvements, which must be relentlessly pursued by the Brazilian scientific community. We must have a commitment to the country's future.

The slow release fertilizers, release the nutrients over time, aiming to synchronize with the plant's demand for the nutrient, with the reduction of its loss to the environment. The use of this fertilizer can promote benefits, such as reducing the need for top dressing and reducing labor costs. The objective of this work was to test the efficiency and adequ ate doses of P in slow release fertilizer (SRF) in base fertilization, as well their influence in cover fertilization in eucalyptus plantations. Was tested four doses of base fertilization (0, 85, 125 e 165 g of SRF plant-1 applied with SRF) and two applications of cover fertilizer (0 and 80g of N:P:K-20:00:20). Height, diameter at ground height, canopy area, dry mass of the aerial part was measured. The dose of maximum technical efficiency was calculated. There was an interaction between height and canopy area, which demonstrated similar growth with and without cover fertilization for all doses of SRF. We recommend the use SRF at a dose of 125 g of SRF plant-1, without performing cover fertilizer.

O objetivo deste trabalho foi avaliar genótipos de cana-de-açúcar ao parasitismo de P. zeae em condições de casa-de-vegetação. Dois ensaios foram conduzidos em delineamento de blocos casualizados, com 12 tratamentos (genótipos) de cana-de-açúcar com 3 repetições. A partir de uma população pura de P. zeae foi inoculada em cada parcela 1000 indivíduos de P. zeae e posteriormente calculado o Fator de Reprodução (FR). Dos doze genótipos de cana-de-açúcar avaliados, 25% demonstraram comportamento suscetível (FR>1) enquanto 75% foram resistentes (FR<1) quando submetidas ao parasitismo de P. zeae. As cultivares RB867515 e RB966928 e os genótipos RB036168, RB036059, RB036066, RB966229, RB036145, RB046209 e RB036153, se mostram genótipos promissores ao cultivo em canaviais infestados de P. zeae. Este estudo é de grande importância para conhecer o comportamento de resistência dos genótipos de cana-de-açúcar a P. zeae, e desse modo, auxiliar estudos posteriores visando o controle do patógeno.
