Effects of highly corrosive pipe wall and disinfectant constituent on the chlorine decay behavior in drinking water
Authors: Ma Kai , Yu Chuan , Xie Wenxi , Fan Dongmei 
Published: April 2023

Abstract
In this study, a pilot-scale pipeline reactor and refined total chloramine decay model were employed to study the effects of the highly corrosive pipe wall and three kinds of disinfectant constituents on the chlorine decay behavior. The bulk decay coefficient, kbulk for NaClO, NaClO + NH3·H2O, and NaClO + (NH4)2SO4 were 0.011, 0.004, and 0.004 h−1, respectively. By resorting to the refined total chloramine decay model, the comprehensive wall decay coefficient kwall appeared in the ascending order of NaClO, NaClO + NH3·H2O, and NaClO + (NH4)2SO4. The remarkable contribution of the aged cast iron pipe wall to overall total chlorine residual decay was manifested by the ratio, kwall/kbulk. The pipe wall-induced decay was related to microbe consumption and electrochemical corrosion as indicated by variations in total organic carbon (TOC), NO2−-N, NO3−-N, and Fe residual. The larger kwall for NaClO + NH3·H2O (0.720 h−1) relative to NaClO (0.465 h−1) was mainly attributed to enhanced nitrifier-mediated microbe consumption. The largest kwall for NaClO + (NH4)2SO4 (0.864 h−1) was due to the further promoted microorganism regrowth and metabolization as evidenced by the SO42- declining behaviors. On this basis, it was suggested to minimize extra inorganic salt introduction into treated water to constrain microbial development in drinking water distribution system (DWDS). Temporal-free chlorine disinfection was also recommended for the chloraminated DWDS before the critical temperature.

AbstractExcessive discharge of phosphorus can produce eutrophication in aquatic environments, damaging public health, the living environment, and the economy. The conventional mechanical–biological phosphorus removal methods are not suitable for small rural domestic sewage due to the features of small scale, scattered distribution, intermittent emission, and large fluctuation. This work evaluated electrocoagulation (EC) with industrial steel as electrodes on small rural domestic sewage. Results showed that the best performance was achieved at a current density of 1 mA/cm2, electrode distance of 2 cm, electrode number of 2, pH of 7, and Hydraulic Retention Time of 30 min, respectively. Under optimum conditions, the EC process removed 93.91% phosphorus while consuming around 0.25 kWh/m3 of electricity. In addition, the electrode passivation of EC was further investigated; the long-term research found that the phosphorus removal efficiency only decreased by 4.34% after 10 days of continuous flow operation, and the operational energy consumption was 0.07 kWh/m3 at a Cl– concentration of 500 mg/L.

Authors: Osornio Muñoz Nadia Maricela 
Published: April 2023

La serie fotográfica Más allá del canto apocalíptico busca explorar nuevas formas de abordar la degradación histórica del Zócalo capitalino a través de un ejercicio imaginativo y subversivo. El concepto central es el regreso a la historia acuática de la Ciudad de México para repensar nuestra relación con el agua, en el contexto del cambio climático actual. La serie integra también otros elementos, como la presencia de espacios verdes en la superficie —en forma de chinampas— y en la parte subterránea, junto con el metro, las ruinas prehispánicas y especies animales. A través de esta propuesta, se busca ir más allá de las narrativas apocalípticas y proponer escenarios posibles si la industria y los gobiernos adoptan medidas que permitan una reversión gradual del deterioro ambiental.

Authors: Urrejola-Contreras Gabriela Paz , Pérez-Lizama Miguel Angel 
Published: April 2023

Introducción: Las evaluaciones de opción múltiple constituyen el instrumento ampliamente usado en ciencias para evaluar al estudiantado; sin embargo, la reciente pandemia exigió adaptar este tipo de instrumento al entorno virtual. Este contexto requirió valorar la calidad de los instrumentos mediante índices de discriminación, consistencia interna y relacionarlo con el rendimiento académico.
Objetivo: Evaluar los instrumentos de evaluación empleados en modalidad online durante la pandemia por COVID-19, y el rendimiento de los estudiantes en ciencias de la salud.
Método: Se realizó la revisión de los 5 instrumentos de la asignatura Estructura y Función formados por 290 bancos de preguntas aleatorias para evaluar cada contenido en estudiantes de primer año durante el 2020 en la escuela de ciencias de la salud en la Universidad Viña del Mar. Se analizaron los datos obtenidos a partir de la plataforma virtual y se interpretaron los índices de discriminación, facilidad, eficiencia discriminativa, consistencia interna y rendimiento académico mediante un informe que fue compartido con los docentes para identificar los parámetros de calidad y validez.
Resultados: Del total de bancos de preguntas evaluados, un 70.2% de las preguntas presentaron adecuada discriminación y solo un 5.6% debieran ser eliminadas. El certamen dos obtuvo el menor rendimiento promedio 3.9 ± 0.99; sin embargo, presentó la consistencia interna más alta: 81%. Al comparar todos los instrumentos se observó una mejora gradual en la formulación, reflejada en el examen final, en el que además el rendimiento académico concuerda con el promedio del semestre 4.2 ± 0.92.
Conclusiones: El rendimiento académico debe ponderarse en relación con la calidad del instrumento formulado en el que, a menor índice de facilidad, existe una mayor consistencia interna, representado por la mayor eficiencia discriminativa de las preguntas. El proceso de diseño y formulación de los instrumentos debe cuidar y examinar estas pautas para resguardar criterios de calidad.

В настоящей статье приводятся результаты численных исследований тепловой эффективности неоднородных вертикальных ограждений на примере нескольких вариантов конструктивного решения наружных стен здания. Исследования проводились с использованием вычислительного комплекса TEPL, разработанного для расчета трехмерных температурных полей на основе метода контрольного объема. Приведены результаты анализа распределения температур на поверхностях теплообмена, позволившие определить зоны излишних тепловых потерь в исследуемых конструкциях. Выявлены значительные тепловые потери на откосах оконных проемов, которые следует учитывать при расчете приведенного сопротивления теплопередаче ограждения. Вычислительный комплекс TEPL позволяет не только корректно оценить тепловые потери, но и автоматически получить величину приведенного сопротивления теплопередаче конструкции ограждения с учетом всех особенностей её конструктивного решения.
Analyzing Code-Switching used by Agnez Mo
Authors: Iman Topan Rahmatul 
Published: April 2023

Abstract: Using language as a communication tool requires a relationship between people and society. This relationship is referred to as sociolinguistics. In Indonesia, many people speak more than one language. This phenomenon can be clearly observed in television talk shows, in which celebrities or public figures use code-switching. One celebrity who frequently switches from Bahasa Indonesia to English is Agnez Mo. This essay aims at investigating the identity Agnez Mo constructs using code-switching, and at examining the grammatical aspects in the production of code-switching. Regarding the data collection, as the study focuses on the analysis of the code-switching performed by Agnez Mo on the conversation with Deddy Corbursier (the host) on the Hitam Putih talk show on one of TV channels on YouTube was downloaded. The data collected were analyzed in five stages: listening to the recording, re-listening to the recording while transcribing the conversation, identifying the words that will be analyzed, analyzing the specific phenomenon, and checking the data. The data shows that she builds two different identities, one being multicultural identity and the other religiosity. Also, the data shows that Agnez Mo switches her language using the three types of code-switching: extrasentential, inter-sentential, and intra-sentential code-switching.

Abstrak: Penelitian ini bertujuan untuk menganalisis prinsip Meta Karuna dan penerapannya di dalam Yayasan Buddha Tzu Chi, sebuah yayasan sosial kemanusiaan yang didirikan oleh Master Cheng Yen di Taiwan yang bergerak dalam banyak aspek sosial. Penelitian ini menggunakan metode penelitian kualitatif dengan teknik analisis deskriptif untuk sampai pada pertanyaan penelitian yang dimaksud dan menemukan bahwa prinsip cinta kasih universal yang diterapkan di Yayasan Tzu Chi mengasumsikan bahwa Yayasan didirikan untuk semua orang tanpa memandang ras, golongan, kepercayaan, atau agama. Karena Master Cheng Yen menerapkan beberapa filosofi Buddhis dalam ajarannya, juga terlihat bahwa Yayasan Tzu Chi yang disebut sebagai Brahmavihara, terdiri dari empat ajaran penting, dua di antaranya adalah meta dan karuna. Meta adalah ajaran yang mengajarkan setiap manusia untuk memiliki rasa cinta terhadap sesama makhluk ciptaan Tuhan, sedangkan karuna mengajarkan bagaimana berbelas kasih terhadap sesama. Kajian ini menyimpulkan bahwa meskipun Yayasan Tzu Chi tidak mengenal perbedaan antar kepercayaan atau agama, namun beberapa ajaran Buddha masih diterapkan dalam landasannya yang ditinjau secara universal. Meski begitu, ajaran ini ditujukan untuk semua manusia di muka bumi ini.
Kata Kunci: Yayasan Buddha Tzu Chi, Master Cheng Yen, Meta, Karuna.
ENTRE O PADÊ E O INEXPERIENCIÁVEL
Authors: Ribeiro Helano , Gomes Jeean 
Published: April 2023

Esse artigo propõe discussões acerca da poesia de Edimilson de Almeida Pereira estabelecendo um recorte de sua produção, que bebe da fonte das culturas banto e yorubá. Nesse sentido, é uma poesia negra que se inspira na mitologia daqueles povos. Os livros de onde vieram os poemas são: Poesia + (antologia poética 1985-2019) (2019), Poemas para ler com palmas (2017) e Livro de fala (2008). Para lê-los, precisa-se, porém, acessar as epistemologias vindas de África e as entrecruzadas aqui no Brasil. Dessa forma, a base teórica referente à mitologia e a epistemologias negras partiu de Luz (1995), Oliveira (2003; 2007), Ford (1999), Haddock-Lobo (2020), Freitas (2016) e Ribeiro (1996). Tais epistemologias fogem da lógica ocidental, aí Derrida (2014) foi o fulcro teórico, além dos trabalhos de Agamben (2005) e Deleuze e Guattari (2012). Como se trata de uma poesia contemporânea, os trabalhos de Siscar (2010) contextualizaram os poemas de Pereira no aqui-e-agora. É, portanto, na crise que os poemas negros emergem e fluem em um devir da linguagem, evocando uma experiência do inexperienciável.
ANTOLOGIA TINTA

Published: April 2023

O presente artigo examina a antologia Tinta: poetisas afrodescendientes enquanto produção de conhecimento por parte de poetas amefricanas contemporâneas no Uruguai. Tal exame propõe a hipótese do corpo como categoria de análise literária, examinando, brevemente, a centralidade epistemológica do lugar, assim como uma relação entre corpo e lugar como chave de leitura à referida antologia. Parte-se da hipótese de que qualquer literatura nacional (inclusive, a poesia afro-uruguaia) pode ser tomada, de modo econômico, como prefácio a um corpus mais amplo de literaturas amefricanas. Espera-se que os resultados desta investigação ofereçam subsídios a uma compreensão científica das literaturas amefricanas e, por conseguinte, do lugar amefricano como lugar de conhecimento.
An Analysis of Organizational Support for Telecommuting in Public Accounting Firms
Authors: Dalton Derek W. , Garrett Jace B. , Harp Nancy L. , McPhee Gregory P. 
Published: April 2023

ABSTRACT
Research suggests that organizational support for alternative work arrangements (AWAs) is essential for the effective implementation of AWAs in public accounting, yet studies consistently suggest that such organizational support is lacking. Despite mass adoption of telecommuting (one type of AWA) during the COVID-19 pandemic, recent evidence suggests that firms vary greatly in the extent to which they plan to support telecommuting in the post-pandemic environment. Using a sample of 133 public accounting professionals, we explore whether several factors under the organization’s control influence perceived organizational support for telecommuting, and whether such support is linked with perceived career penalties from telecommuting usage and turnover intentions. We find that supervisor support for personal/family needs and procedural justice regarding telecommuting requirements are positively associated with perceptions of organizational support for telecommuting. Further, greater perceived organizational support for telecommuting is associated with both lower perceived career penalties from telecommuting usage and lower turnover intentions.

Published: April 2023

Introduction. Data on elements of heat supply systems of the Russian Federation (heat sources, heating networks) are given as well as the main energy characteristics. The main problems in the industry are indicated. It is concluded that it is necessary to optimize the operation of heat supply systems in all its links and at all stages of the life cycle.Materials and Methods. For optimal control of thermal power systems, the authors consider it expedient to create a digital information model of each element of the system at each stage of the life cycle, including: - three-dimensional engineering digital terrain model; - three-dimensional engineering digital model of heating networks, taking into account adjacent communications and structures;- operational digital model of the heat supply system on the platform of the geoinformation software complex Zulu21. The technology of data exchange in IFC format between software complexes is given. The necessity of verification of the operational model using the data of field measurements on the physical model of the heat supply system is indicated.Results. The creation of a digital information 6D model of the heat supply system allows you to move to a higher level: intelligent dynamic control of a complex energy system (neurocontrol). The SCADA software package in online mode collects the necessary information (temperature, pressure, coolant flow) from sensors installed at characteristic points of the system. All information is transmitted to Zulu, a software package with built-in support for OPC technology to receive data from a SCADA system. The received data is fed into the ZuluGis software package, which includes the ZuluThermo module, with a loaded digital information model of the heat supply system. The actual thermal and hydraulic modes of the system are calculated in the module. Data on the optimal and actual thermal-hydraulic modes are transmitted to the neurofeedback unit for comparison and management decisionmaking. The decision is transmitted to the appropriate controller to initialize actions to change a parameter.Discussion and Conclusions. A technology for developing a digital information model for elements of a heat supply system at all stages of its life cycle is proposed. The creation of a digital information 6D model of the heat supply system allows you to move to a higher level: intelligent dynamic control of a complex energy system (neurocontrol). The use of intelligent control makes it possible to improve the quality of decisions made, significantly increase the energy efficiency of heat supply systems and the quality of services provided to the end user.

Published: April 2023

Introduction. The article tackles the problem of finding the most efficient in terms of metal consumption I-shaped crosssection for creating a frame of variable section. In this paper from various options of creating the variable in length frame elements the authors study the option of creating the elements from the ordinary I-beams by diagonal slitting followed by welding as one of the most technologically advanced one. To obtain the most efficient in terms of metal consumption cross-section, it is proposed to use a monosymmetric I-beam composed of two different assortment items.Materials and Methods. The review of scientific works related to the topic of designing structures from I-beams allowed the authors to compile a methodology for calculating the optimal section parameters. The implementation of this methodology makes it possible to draw the parameters for finding the most efficient for application cross-sections from the existing assortment of rolled I-beams.Results. The object considered in this study is a frame of a building designed as the braced frame structure from welded single-span frames with elements of variable cross-section (code 828KM). The calculation was made in accordance with the proposed methodology. The results of the calculation show that the use of a monosymmetrical I-beam, composed of two different I-beams, gives opportunity to use the load-bearing capacity of the section to the fullest extent.Discussion and Conclusions. In the result of implementation of the proposed methodology, it became possible to reduce the mass of an I-beam of a variable cross-section compared to the serial one used under similar loads. The result of the study allows us to conclude that the use of frames of variable section formed of I-beams of various cross-sections by diagonal slitting and subsequent welding in the construction of industrial frame buildings is highly perspective.
