Проведен анализ тенденций развития камер сгорания энергетических газотурбинных установок большой и средней мощности передовых производителей, идущих по пути существенного повышения КПД установок, увеличения топливной гибкости при сохранении экологических требований. Продемонстрирован опыт создания малоэмиссионных камер сгорания (МЭКС) во Всероссийском теплотехническом институте. Приведены результаты испытаний МЭКС ГТ-16П в одногорелочном отсеке при полных параметрах. Показана ее доработка до двузонной, что позволило существенно расширить границы устойчивого малоэмиссионного горения в широком диапазоне температур наружного воздуха. При допустимых значениях NOx удалось достичь температуру газов на выходе из камеры сгорания 1700 °C. Проанализированы конструкции горелочных устройств МЭКС газотурбинных установок, позволяющие избежать основных проблем, возникающих при сжигании топлива с большим содержанием водорода, а именно: проскока пламени в зону предварительного перемешивания, высоких потерь давления на горелках и неустойчивости процесса горения. Показано, что данные конструкции не содержат лопаточного завихрителя и выраженной зоны предварительного перемешивания.

This paper presents an analysis of trends in the development of combustion chambers for high- and medium-power gas turbine power units of advanced manufacturers pursuing a significant increase in the efficiency of the plants and fuel flexibility while maintaining environmental requirements. The experience in developing low-emission combustion chamber (LECC) in the All-Russian Thermal Engineering Institute is presented. The results of tests of the GT-16P LECC in a single-burner compartment with full parameters are presented. Its modification to a dual-zone configuration is shown, which made it possible to significantly extend the range of stable low-emission combustion over a wide temperature range of outside air. For acceptable values of NOx, it was possible to reach a combustor exhaust gas temperature of 1700 °C. An analysis is made of the designs of gas turbine LECC burners allowing to avoid the main problems arising when burning fuel with a high content of hydrogen: flame breakthrough into the premixing zone, high pressure losses on burners, and combustion instability. It is shown that these designs do not contain a blade swirler and a pronounced premixing zone.

Образование оксидов азота при горении угля или биотоплива из связанного с топливом азота остается важной экологической проблемой. В качестве простейшей модельной системы для описания горения угля можно использовать молекулу пиридина, которая, с одной стороны, имеет ароматическую структуру, а с другой - содержит в своем составе атом азота. Данная работа посвящена теоретическому изучению путей реакции взаимодействия пара-пиридила с молекулярным кислородом. Была построена поверхность потенциальной энергии взаимодействия пара-пиридила с молекулярным кислородом. Радикал пара-пиридил безбарьерно присоединяет молекулу кислорода с образованием радикала PyOO, далее реакция может пойти по трем путям, приводя к четырем возможным продуктам: 3H-пиррол, HCO + HCN, 1λ2-пиррол и 1λ3,4-оксазин.

The formation of nitrogen oxides during combustion of coal or biofuel containing fuel-coupled nitrogen is an important environmental problem. As the simplest model system used to describe coal combustion, one can use a pyridyl molecule, which, on the one hand, has an aromatic structure and, on the other hand, contains a nitrogen atom in its structure. This paper describes a theoretical study of the reaction of para-pyridyl interaction with molecular oxygen. A surface of potential energy interaction of para-pyridyl interaction with molecular oxygen is constructed. The para-pyridyl radical barrierlessly attaches an oxygen molecule with formation of the PyOO radical, and then the reaction can follow one of three paths, leading to four possible products: 3H-pyrrole, HCO + HCN, 1λ2-pyrrole, and 1λ3,4-oxazine.

Authors: Chai Haojie , Li Lu
Published: July 2024

Efficient utilization of wood is inseparable from high-quality drying, and analysis of its free shrinkage performance is essential to optimize the drying process. This study took Pinus sylvestris L. sawn timber (500 mm×200 mm×50 mm) as the research object and adopted the image analysis method to analyze the influence rules of different temperatures and axial positions of the test material on the free dry shrinkage coefficient of each layer of specimens in the thickness direction. The free shrinkage coefficients of each layer in the thickness direction of the test material decreased from the maximum value of the first layer near the tangential direction (0.282%, 0.275%, 0.267%, at 60 °C, 80 °C, and 100 °C, respectively) to the minimum value of the ninth layer near the radial direction (0.248%, 0.249%, 0.227%); except for the near-radial layers, when temperature increased from 60 °C to 100 °C the free shrinkage coefficients of other representative layers decreased with increased temperature. The first layer’s free shrinkage coefficient decreased from 0.282% to 0.267%, and the fifth layer decreased from 0.264% to 0.243%. The difference of free shrinkage coefficients between corresponding layers at different axial positions of the test material was less than 0.017%, and the size stability of the corresponding layers at axial positions was high.

APPLICATION OF AN ADAPTATION APPROACH THROUGH NARRATIVE COMPARISONS IN THE NOVEL AND FILM TWILIGHT
Authors: Hartati Yolla Ajeng , Kustanti Dewi , Permanaludin Udayani
Published: July 2024

In the realm of fine arts, it is common for one form of art to draw inspiration from another, a process known as transformation. This research focuses on the film adaptation of literary works, examining the ecranization of novels into films and the use of adaptation theory to convert novel texts into visual films while preserving the essence of the novel as a hypogram. The study employs a qualitative descriptive method, utilizing close reading and close viewing techniques. It classifies the transformations using Pamusuk Eneste's ecranization (1991) approach and Seymour Chatman's interpretation theory (2018) of the change process in novels and films. The findings reveal that films often include additional stories to convey the setting more explicitly. Although various settings are altered, these changes are justified as it is often impractical to visually depict the atmosphere detailed in the novel. The introduction of new characters in the film aligns with the expanded plot, necessitating the inclusion of characters absent in the novel. Additionally, the visualization of characters in the film undergoes modifications, yet remains consistent with the novel's descriptions. Backgrounds are condensed to fit the film's plot, resulting in the omission of some novel locations in the film adaptation.Keyword: transformation, ecranization, novel, film, twilight

Published: July 2024

Deixis is an essential component of communication that must be carefully considered to improve its efficiency and prevent misunderstandings. This study aimed to analyze Suho EXO’s speech at the Stanford Korea Program 20th Anniversary Conference focused on the discourse deixis and types of discourse deixis used and investigate their functions. The research employed a qualitative method. A theory used in this study was based on the Levinson’s deixis theory (1983). Discourse deixis refers to deictic references to segments of discourse relative to the speaker’s current position within the discourse. Discourse deixis, like anaphora and cataphora, can serve as a cohesive device within a text. The analysis found 53 deictic expressions in 38 utterances in the speech. The types of discourse deixis found in the speech were it (20 data), this (10 data), and (7 data), these (4 data), but (4 data), that (2 data), so (2 data), those (1 datum), there (1 datum), or (1 datum), and actually (1 datum). Moreover, 34 data contained anaphora functions, such as and, it, this. Meanwhile, 19 data contained cataphora functions, such as that, but, or, so, these, those, and actually. Therefore, paying attention to deixis leads to more distinctive, accurate, and compelling conversations.Keyword: discourse deixis, speech, suho EXO

Kalsium, magnesium dan vitamin D3 adalah komponen yang penting untuk pertumbuhan udang. Tujuan dari penelitian ini adalah untuk mengevaluasi kinerja pertumbuhan, tingkat kelangsungan hidup dan kualitas air media pemeliharaan udang Litopenaeus vannamei setelah pemberian pakan dengan suplementasi kombinasi kalsium, magnesium dan vitamin D3 pada dosis yang berbeda. Udang diberi pakan dengan perlakuan yang berbeda yaitu kontrol (tanpa suplementasi HYPEROL yang berisi kombinasi kalsium, magnesium dan vitamin D3) dan empat tingkat suplementasi kombinasi HYPEROL yaitu 2,5 mL kg-1; 5 mL kg-1 ; 7,5 mL kg-1; 10 mL kg-1 pakan. Selama penelitian udang dipelihara dalam akuarium dengan ukuran 40x25x30 cm3 yang berisi 25 L air laut yang didesinfeksi pada kepadatan tebar 100 larva m-2. Penelitian ini menunjukkan bahwa suplementasi kombinasi kalsium, magnesium dan vitamin D3 pada konsentrasi hingga 10 mL kg-1 secara signifikan dapat meningkatkan pertumbuhan udang vaname. Kombinasi kalsium, magnesium, dan vitamin D3 yang terkandung dalam HYPEROL memiliki peran sinergis untuk memastikan keseimbangan kalsium yang optimal, sehingga berpengaruh terhadap pertumbuhan udang vaname.Calcium, magnesium, and vitamin D3 are vital feed components to support shrimp growth. This study aimed to evaluate the growth performance, survival rate, and water quality culture of Pacific whiteleg shrimp Litopenaeus vannamei fed with dietary supplementation of a combination of calcium, magnesium and vitamin D3 with different dosages. The treatments in this study consisted of shrimp fed with a control diet (without supplementation of HYPEROL containing a combination of calcium, magnesium and vitamin D3) and four levels of HYPEROL supplementation, i.e., 0; 2,5 mL kg-1; 5 mL kg-1; 7,5 mL kg-1; 10 mL kg-1. Larvae were reared in the tank with a dimension of 40x25x30 cm3 containing 25 L of disinfected seawater at a stocking density of 100 larvae m-2. The present study demonstrated that dietary supplementation of HYPEROL concentrations up to 10 mL kg-1 could significantly improve the growth of Pacific whiteleg shrimp. Combination of calcium, magnesium, and vitamin D3 contained in HYPEROL has an important role in ensuring calcium balance, which affects to the growth of Pacific whiteleg shrimp.
Patient expectations of benefit from physiotherapy and relationship to self-reported outcomes: A pilot study
Authors: Barrett Dustin , Pearcy Jennifer , Bourassa Michael , Wassinger Craig A.
Published: July 2024

Research demonstrates that patient expectations have an influence on physiotherapy outcomes, but little is known regarding expectation changes over time. The primary objective of this pragmatic prospective cohort pilot study was to correlate patient expectations at baseline and after 2 weeks of physiotherapy to self-reported patient outcomes at discharge from physiotherapy treatment. Eligible adult patients with a variety of musculoskeletal disorders reported recovery expectations at initial evaluation and after 2 weeks of treatment. Correlations between expectations and self-reported outcome measures were calculated. Seventeen participants completed this study, and made clinically important improvements over the course of care. Expectations at baseline and 2-week time points generally indicated that participants expect to have a positive outcome from physiotherapy treatment. Participants’ baseline expectations were not significantly correlated to outcome measures or clinically important changes. Yet 2-week expectations were significantly correlated with outcomes and the likelihood of achieving clinically important changes in outcome measures. This relationship may be stronger at 2 weeks compared to baseline. Clinicians might consider repeated measuring of patient recovery expectations across the plan of care to best meet patient needs.
Health navigation for people experiencing newly acquired long-term physical disability: A realist-informed integrative review
Authors: Timothy Emily , Deely Jo , Tietjens Donna , Martin Rachelle
Published: July 2024

Navigating healthcare complexities can be challenging for disabled people, leading to challenges accessing services when required, and contributing to inequitable outcomes for disabled people and their families. Physiotherapists may be key health providers for people with newly acquired physical disabilities and may experience these navigational complexities themselves. Health navigators have been postulated as one solution and are well established in services for other health conditions such as cancer and mental health. However, navigation services for disabled people are less well developed and implemented. This realist-informed integrative review aimed to articulate and clarify underlying causal processes of health navigation programmes for people with newly acquired long-term physical disability, particularly within the New Zealand context. A two-phase literature search was conducted using integrative review methods. Two primary foci emerged for navigation programmes – a targeted health focus, directed towards reducing secondary complications and better service use and flow, or holistic health focus, directed towards more aspirational outcomes. Nine mechanisms of effect were identified across the spectrum of navigational programmes, with empowerment and self-determination overarching. Our findings are important for synthesising knowledge about existing navigation programmes and clarifying the aims and outcomes of future programmes addressing the navigational needs of disabled people.

Published: July 2024

Abstract This study developed and tested the validity of a scale that measures skills for managing work from home, such as: informing change, searching for information, establishing priorities, setting and adapting goals, assessing work outputs, distributing tasks, and offering feedback. Participants were 2,038 managers from three Brazilian public organizations. Exploratory, confirmatory, and multigroup factor analyses revealed an 8-item unidimensional structure, excellent reliability indices, and goodness of fit, besides invariance for gender and age groups. The short scale permits testing research models with multiple variables, comparative (voluntary vs. compulsory telework), and cross-cultural studies.

Published: July 2024

Resumo O artigo científico avalia os determinantes da gestão fiscal representada pelo cumprimento dos limites da Lei de Responsabilidade Fiscal (LRF) e o cumprimento da meta do resultado primário. Para atender aos objetivos propostos, fez-se uma abordagem econométrica, na qual se utilizou a variável binária para cumprimento da meta de despesa total com pessoal e do resultado primário por parte das unidades federativas brasileiras. Para a análise dos fatores determinantes, usaram-se dados sociais e contábeis, características do gestor e uma análise de regressão múltipla para dados em painel, examinando o período de 2017 a 2022. No modelo para a despesa total com pessoal, as transferências da União para os estados e a receita tributária favorecem o não cumprimento dos limites da LRF. Por outro lado, para a meta do resultado primário, as transferências, os restos a pagar, a capacidade de pagamento, a escolaridade e a idade do gestor favorecem o cumprimento da meta.

RESUMO A compreensão dos efeitos da microcelulose cristalina em argamassas de revestimento é essencial para projetar materiais mais duráveis, resistentes e eficientes na construção. Dessa forma, o presente trabalho tem por finalidade verificar a influência da adição de teores de 0,2%, 0,4% e 0,6% de microcelulose cristalina (MCC) em relação à massa do cimento nas propriedades no estado fresco e endurecido de argamassas de revestimento. O estudo foi desenvolvido considerando o impacto das adições de microcelulose nas argamassas de revestimento através da consistência, por meio do ensaio flow-table, da densidade de massa, do teor de ar incorporado e do comportamento reológico através do ensaio de squeeze-flow, como também resistência à compressão e à tração na flexão e o módulo de elasticidade dinâmico. Com base nos resultados obtidos, foi possível concluir que a incorporação de microcelulose cristalina resultou na diminuição da consistência das argamassas. Nas concentrações de 0,2% e 0,4% houve um aumento na incorporação de ar, na plasticidade em quinze minutos da mistura e na redução da densidade de massa, indicando que esses percentuais podem atuar melhorando o processo de aplicação, facilitando a execução das argamassas de revestimento. Contudo, após trinta minutos de mistura, foi possível observar uma mudança no comportamento reológico, onde as argamassas com adição de microcelulose cristalina apresentaram uma redução nos deslocamentos em relação à referência, indicando que a alta capacidade de retenção de água da microcelulose cristalina pode influenciar na plasticidade das argamassas ao longo do tempo da mistura. No estado endurecido, foi possível concluir que as adições de microcelulose cristalina de 0,2% e 0,4% não resultaram em melhorias nas propriedades das argamassas de revestimento.

Published: July 2024

RESUMO Este trabalho considera o aspecto probabilístico da organização do texto a partir da instanciação. Cada instância manifesta de texto se associa à tipologia textual, tanto pelo contexto - como se registra amplamente na literatura - quanto pela configuração linguística mais provável, que é o foco deste trabalho. Descrever como a organização de probabilidade e frequência, assim como os mecanismos pelos quais as frequências emergem, motiva uma configuração linguística e determina como um texto é instanciado torna-se passo necessário para incluir propriedades quantitativas na modelagem. O artigo parte de um corpus de procedimentos, Subcorpus1 - experimentos científicos e receitas; e Subcorpus2 - referente à atividade social de “assar bolo”. Em seguida, identifica o perfil metafuncional dos textos e estabelece regras de associação entre os sistemas para identificar sua chavicidade. Por fim, aplica a metodologia da dinâmica de sistemas. Nos resultados, descrevem-se os mecanismos de subpotencialização, bem como determinam as probabilidades para uma instância ao mesmo tempo em que são constrangidos pela variação do registro. O trabalho aponta a alternativa complementar à análise dos gêneros para se compreender como os textos se organizam e são estruturados.
“Viver da Arena”: casas, práticas econômicas e temporalidades pós-pandêmicas
Authors: Fernandes Bruno Guilhermano
Published: July 2024

Resumo Neste artigo, analiso um conjunto de relações que entrelaçam casas, práticas econômicas e temporalidades, nos entornos da Arena do Grêmio, estádio de futebol em Porto Alegre. A imbricação entre espaços residenciais e espaços comerciais é um aspecto central no contexto de estudo, evidenciada pela ativação de um circuito comercial em casas nas adjacências dessa arena multiúso. Apresentar a forma pela qual as pessoas analisam diferentes marcadores temporais se traduziu em um caminho para identificar fluxos, práticas comerciais e os modos pelos quais temporalidades pandêmicas foram vivenciadas. Situarei a análise em casos que permitem refletir sobre como as consequências, econômicas e sanitárias, da pandemia de Covid-19 foram vividas indissociavelmente. A partir da etnografia, demonstro como diferentes temporalidades fomentaram mudanças nas casas, atravessaram experiências familiares e modularam expectativas à superação de crises, representando o advento de um período pós-pandêmico.

Published: July 2024

Resumo Esta pesquisa, exploratória e de análise documental, mapeou os critérios de elegibilidade à política de cotas do Sistema de Seleção Unificada (Sisu), para estudantes com deficiência, estabelecidos por 62 universidades federais. Foram analisados os editais e os termos de adesão dos processos seletivos de 2019, a partir dos fundamentos do modelo social de deficiência, da Convenção sobre os direitos da pessoa com deficiência e da Lei Brasileira de Inclusão (LBI). Os resultados indicam que as normas se alinham ao modelo médico e desconsideram a concepção da Convenção e da LBI. Apesar de ser um processo unificado, há significativas diferenças nos critérios e exigências para a comprovação da deficiência em cada universidade, o que pode concorrer para a fragilização da política e da segurança jurídica aos candidatos.
(Re)thinking bioethics: intersectional analysis of sexual and reproductive rights
Authors: Petra Priscila Cardia , Caetano Karina de Cássia , Barbosa Samantha Vitena , Chaves Maria Clara Conrado de Niemeyer Soares Carneiro
Published: July 2024

Abstract Bioethics, developed during the post Second World War in North America, is defined as a multidisciplinary epistemological field centered on conciliating biological knowledge and human values. This paper discusses the political-social dimension of bioethics from an intersectional approach with anti-oppression perspectives, that is, anti-capitalist, feminist, and anti-racist perspectives. We propose other conceptions for this field of knowledge, claiming its positioning. By rethinking bioethics in an expansive manner, this paper is propositional to thought and encourages new possibilities. To exemplify the intersection between anti-oppression agendas and bioethics, we approach themes related to sexual and reproductive rights.
Bioethical review on the legality of assisted dying in Ecuador
Authors: González Andrés Felipe Mercado , Pineda Camila Fernanda León , Martinez Fernando Mauricio León
Published: July 2024

Abstract The legality of assisted dying is a controversial matter worldwide due to bioethical aspects. In countries such as Luxembourg and Canada, euthanasia was approved, with positive impacts on the quality of life of patients; however, there are negative aspects, such as not taking palliative options into consideration. This descriptive literature review considered publications from the last five years with bioethical approaches in favor of assisted dying, based on the importance of definitively alleviating patient symptomatology, in addition to providing quality of life, but also noting that in the long term the legality of this procedure may lead to medical dehumanization. Ecuador’s Comprehensive Organic Criminal Code presents ambiguous articles for and against assisted dying, with legal loopholes that preclude its application in the health care system. Despite solid arguments for and against euthanasia, the decision must be adapted to the context of the patient and health care system.
Revisión bioética acerca de la legalidad de la muerte asistida en el Ecuador

Published: July 2024

Resumen La legalidad de la muerte asistida es controvertida en todo el mundo debido a aspectos bioéticos. En países como Luxemburgo y Canadá, la eutanasia ha sido aprobada, generando impactos positivos en la calidad de vida de pacientes; sin embargo, hay aspectos negativos, como el abandono de opciones paliativas. Esta revisión bibliográfica descriptiva consideró publicaciones de los últimos cinco años con enfoques bioéticos a favor de la muerte asistida, con base en la importancia de aliviar definitivamente la sintomatología del paciente, además de proporcionar calidad de vida, pero refirió también que, a largo plazo, la legalidad de este procedimiento puede acarrear la deshumanización médica. El Código Orgánico Integral Penal del Ecuador presenta artículos ambiguos a favor y en contra de la muerte asistida, con brechas legales que no permiten su aplicación en el sistema de salud. Aunque existan argumentos sólidos a favor y en contra de la eutanasia, la decisión debe ser adaptada al contexto del paciente y del sistema de salud.

Published: July 2024

Abstract The study investigated home mortality during the SARS-CoV-2 pandemic in Santa Catarina, using secondary data from the Mobile Emergency Care Service characterizing deaths reported by the teams. Analysis of the data, accessed via the state government’s Transparency Portal, uncovered a rise in deaths attended to by emergency teams in the area. It also highlighted an average increase of 2.16 per 100,000 residents in the mortality rate attributable to non-specific cardiovascular diseases between 2019 and 2022, distinguishing Santa Catarina from the rest of Brazil. This contrast could be linked to inadequate management of risk factors and comorbidities during the pandemic. The findings underscore the need for preventive measures to alleviate adverse impacts on home mortality and enhance healthcare services, particularly concerning equity in the allocation of limited resources amid the pandemic.

Resumo O estudo investigou a mortalidade em domicílio durante a pandemia de SARS-CoV-2 em Santa Catarina, utilizando dados secundários do Serviço de Atendimento Móvel de Urgência caracterizando óbitos notificados pelas equipes. A análise dos dados, acessados no Portal da Transparência do governo estadual, revelou aumento nos óbitos atendidos pelas equipes de urgência na região. Destacou-se também incremento médio de 2,16/100 mil habitantes na taxa de mortalidade por doenças cardiovasculares inespecíficas entre 2019 e 2022, diferenciando Santa Catarina do restante do Brasil. Essa disparidade pode estar associada à falta de controle dos fatores de risco e comorbidades durante a pandemia. Os achados ressaltam a necessidade de medidas preventivas para mitigar os efeitos adversos sobre a mortalidade domiciliar e melhorar os serviços de saúde, especialmente em relação à equidade na distribuição de recursos escassos durante a pandemia.

Published: July 2024

Resumo Este trabalho aborda a questão das interações online nas aulas de Língua Brasileira de Sinais (Libras) como segunda língua (L2) para ouvintes. Ancora-se em Rioult, Marron e Pereira (2021), para tratar do ensino virtual em tempos de pandemia e destaca o distanciamento psicológico e comunicacional que a comunicação mediada por computador pode oferecer às aulas. Toma as considerações de Xavier (2001) para descrever as características das interações em L2 e aponta as especificidades do input e da produção linguística para as aulas de Libras. Por meio da análise documental e do método observacional, são elencados os principais desafios verificados nas interações ocorridas nas aulas de Libras as quais foram ministradas em contexto de ensino fundamental por cinco bolsistas do Curso de Letras Libras. Os resultados da experiência pedagógica analisada mostram que gerenciar a participação de intérpretes de Libras e surdos oralizados durante as interações online nas aulas de Libras é uma tarefa bastante desafiante, assim como a administração do uso adequado de suportes visuais (câmeras, telas e chat). Conclusivamente, este trabalho aponta que a experiência de ensino de Libras como segunda língua no ensino fundamental, realizada no período pandêmico, revelou diferentes desafios linguísticos e técnicos para a interação buscada, os quais precisam ser superados a fim de que as aulas, tanto remotas quanto presenciais, apresentem a qualidade necessária para alcançar seus objetivos de aprendizado.

Automation in education: trending issues concerning Artificial Intelligence
Authors: Lima Giselle de Morais , Ferreira Giselle Martins dos Santos , Carvalho Jaciara de Sá
Published: July 2024

Abstract Discourses on technology have been marked by dichotomic, albeit predominantly optimistic, value judgments on the place of artifacts in educational contexts. In academia itself, digital artifacts are often advocated as solutions to educational problems that are, in fact, complex and historically rooted. This article tackles a question on the discourses that surround technologies based on Artificial Intelligence (AI): are old discourses - that hinge on the naturalization of technology - being reproduced? Based upon a review of academic literature on AI in education, conducted within the scope of a broader ongoing research project, the text presents an overview of key discussion points raised in the last five years in the field of Education. On the one hand, there seems to be great enthusiasm for AI and its promises; on the other, concerns are highlighted regarding teaching as a profession - in the extreme, worries with the replacement of the teacher by the machine, a fear that is also not new. However, our review suggests that, beyond unrestrained optimism or pessimism, discussion agendas address important points considered with basis on in-depth theorization and solid empirical data, which can open paths other than the development and acceptance of technologies in purely solutionist perspectives.
INTEGRATION OF THERMAL ENERGY STORAGE MATERIALS IN HEAT PIPE EVACUATED TUBE SOLAR COLLECTOR SYSTEMS FOR ENHANCED SOLAR THERMAL PERFORMANCE

This study investigates integrating thermal energy storage materials (TESM) with a heat pipe evacuated tube solar
collector (HP-ETSC) in a water tank. Three TESMs (paraffin wax, RT27, and RT35) were examined numerically
using COMSOL software, and experiments were conducted. Different design parameters were discussed, including
water tank thickness, TESM tank thickness, TESM types, flow rate, and environmental conditions. The integration
of TESM into the HP-ETSC allows the evaluation of various thermal performances, including average water tank
temperature, hot water outlet temperature, and duration of hot water availability after sunset. The findings indicate
a maximum temperature difference of approximately 37°C at 13:00 on March 19 without TESM. However, with
RT35, the temperature difference is around 34.27°C, and with RT27, it is approximately 33.4°C. Additionally, the
temperature difference is approximately 2°C higher when TESM is not utilized during the three months at sunset.
These results demonstrate improved thermal performance compared to a similar system without TESM. Thermal
energy transmission from TESM to water is relatively low, resulting in slightly higher outlet water temperature at
night. During cloudy periods, RT27 and RT35 TESM types maintain their melting temperature from 11:00 to 20:00.
A water storage tank thickness of 35 mm yields the highest temperature difference with RT27 and RT35 TESM.
Increasing TESM thickness allows for more mass and latent heat storage, leading to up to 3.5 hours of heat release. On
a mostly sunny day, such as January 9, the HP-ETSC stops heat release around 16:30 without TESM, while the TESM
plates prolong the discharge duration by three hours.
Palms behind the Smog: Strange Energies in Mawsim al-hijra ilā al-shimāl (Season of Migration to the North)
Authors: Olszok Charis
Published: July 2024

This essay argues for the primacy of energy as an impetus in the writing of the Sudanese author al-Tayyib Salih. Taking his most famous novel, موسم الهجرة إلى الشمال (1966; Mawsim al-hijra ilā al-shimāl; Season of Migration to the North), as a case study, it explores the significance of climatic factors and of changes to energy regimes in the novel's plot, characterization, intertextuality, and postcolonial critique. Through the character of Mustafa Saʿid, it argues for a posthuman impulse in the novel, as Mustafa uncannily transforms from Faustian archetype to a fantastical, nonhuman force. It concludes by shifting to alternative forms of energy within Salih's writing, as the spiritual energy of the Sufi “unseen” meets the unheeding world of atoms, supercharged with new energies in the modern era.
Sexual Violence and Racial Capitalism: James Baldwin's Prisons, 1969–74
Authors: Dango Michael
Published: July 2024

This essay engages with James Baldwin's work on prison rape in the early 1970s: his directing of John Herbert's play Fortune and Men's Eyes while in Turkey (1969–70), his nonfiction book No Name in the Street (1972), and his penultimate novel, If Beale Street Could Talk (1974). Over the course of these works, Baldwin theorized that sexual violence constitutes racial capitalism by mediating between the two state-organized institutions tasked with securing the primitive accumulation and surplus value on which racial capitalism relies: the family (and, more broadly, heterosexuality) and the prison (and, more broadly, policing). In turn, Baldwin helps converge two intellectual traditions that developed after him, the black radical and Marxist feminist traditions, in order to explain how sexual violence expropriates both forced productive labor and unpaid reproductive labor through its production of racialized gender and kinlessness.
The verbal expression of events of change in Bulgarian
Authors: Karagjosova Elena
Published: July 2024

The paper explores the verbal expression of events of change in Bulgarian, a Slavic language with a uniquely complex verbal system involving triplets of imperfective, perfective and secondary imperfective verbs and aspectual tenses like Aorist and Imperfect. It starts from the observation that English predicates involving events of change generally correspond to Bulgarian triplets of lexically related but aspectually differentiated verbs. It addresses this asymmetry by investigating the properties of the events in the denotation of the triplet members in terms of Rothstein’s (2004) aspectual features [±stage] and [±change]. The paper provides evidence for a systematic mapping between the aspectual properties of the triplet members and Rothstein’s event types and proposes an analysis of the event structure of the triplet members. The findings support both the assumption of independent event types denoted by verbal predicates and the notion of telicity as a VP-level phenomenon, and provide evidence for a strategy of expressing aspectual distinctions in which aspectual properties are not directly tied to the roots of verbal predicates but are partly morphologically and partly lexically encoded.
Equal Chances versus Equal Outcomes: When Are Lotteries Fair and Justified?
Authors: Otsuka Michael
Published: July 2024

According to one potent challenge to the value and fairness of distribution by lot, the lottery chance of receiving a good is lacking in value or otherwise insignificant or irrelevant in comparison with actually receiving the good. To meet this challenge, I show in Section I that the far greater significance of receiving all of an undivided good needn’t undermine the case for equal lottery chances of the whole good, as compared with an outcome involving equally divided portions of this good. I argue in Section II that it mislocates the value of lottery chances to assume that they must contribute, in themselves, to a person’s well-being. Rather their significance primarily resides in their expected instrumental value in delivering goods of independent value. In Section III, I provide an account of when distribution by lot is perfectly fair in spite of the inevitability of an unequal outcome among equal claimants.
The Recent Evolution of the Federal Funds Market and its Dynamics during Reductions of the Federal Reserve’s Balance Sheet
Authors: Anderson Alyssa , Na Dave
Published: July 2024

Following its May 2024 meeting, the Federal Open Market Committee (FOMC) announced that it would slow the pace of its balance sheet reduction starting in June 2024. This will allow for a more gradual transition from an abundant to ample supply of reserves. As reserves decline, conditions in money markets, including the federal (fed) funds market, will be important in judging whether the supply of reserves is approaching ample.

Small-Dollar Loans in the U.S.: Evidence from Credit Bureau Data
Authors: Flagg Jessica N. , Hannon Simona M.
Published: July 2024

Small-dollar loans were brought into the spotlight in March 2020, when five agencies—the Board of Governors of the Federal Reserve System, the Consumer Financial Protection Bureau (CFPB), the Federal Deposit Insurance Corporation (FDIC), the National Credit Union Administration (NCUA), and the Office of the Comptroller of the Currency (OCC)—issued a joint statement encouraging their supervised financial institutions to offer such loans to consumers and small businesses in response to the onset of the pandemic.
Predicting Analysts’ S and P 500 Earnings Forecast Errors and Stock Market Returns using Macroeconomic Data and Nowcasts
Authors: Sharpe Steven A. , Cruz Antonio Gil de Rubio
Published: July 2024

This study scrutinizes the quality of “bottom-up” forecasts of near-term S and P 500 Composite earnings, derived by aggregating analysts’ forecasts for individual firm-level earnings. We examine whether forecasts are broadly consistent with current macroeconomic conditions reflected in economists’ near-term outlook and other available data. To the contrary, we find that a simple macroeconomic model of aggregate S and P 500 earnings, coupled with GDP forecasts from the Blue Chip Survey and recent dollar exchange rate movements, can predict large and statistically significant errors in equity analysts’ bottom-up forecasts for S and P 500 earnings in the current quarter and the quarter ahead. This finding is robust to the requirement that our econometric model is calibrated using only data available at the time of forecast. Moreover, the discrepancy between the macro-model-based earnings forecasts and analysts’ forecasts has predictive power for 3-month-ahead stock returns
