Published: June 2023

Piroliza metanu jest alternatywną do reformingu parowego metodą przetwarzania metanu (gazu ziemnego) do wodoru. Największą różnicą między tymi technologiami jest brak emisji ditlenku węgla w przypadku pirolizy metanu, co biorąc pod uwagę konieczność sekwestracji tego groźnego gazu cieplarnianego w technologii reformingu parowego, powoduje, że piroliza metanu staje się metodą wysoce konkurencyjną, a zainteresowanie nią wśród koncernów paliwowych, firm chemicznych i petrochemicznych stale wzrasta. W niniejszym artykule przedstawiono porównanie wybranych istotnych, perspektywicznych metod otrzymywania wodoru z metodą pirolizy metanu (gazu ziemnego). W porównaniu uwzględniono takie metody jak: reforming parowy, elektroliza wody, piroliza biomasy, fotofermentacja czy gazyfikacja węgla kamiennego. Na podstawie wybranych dostępnych źródeł literaturowych przeanalizowano koszty wytworzenia wodoru poszczególnymi metodami, obejmujące nie tylko cenę surowców, koszt energii, zużycie wody, ale również opłaty za emisję gazów cieplarnianych, koszt dodatkowych surowców i procesów. Pokrótce nakreślono też zalety i wady wybranych metod otrzymywania wodoru. Przeprowadzono analizę ekonologiczną wytypowanych technologii wytwarzania wodoru. Przedstawione wyniki analiz ekonomicznych i ekonologicznych wykazały wysoką przewagę konkurencyjną pirolizy metanu (gazu ziemnego) między innymi nad reformingiem parowym oraz nad elektrolizą wody. Potwierdzeniem korzystnej oceny procesu termicznego rozkładu metanu (gazu ziemnego) jest rosnące zainteresowanie tą technologią wśród dużych zagranicznych koncernów. W artykule zaprezentowano przegląd postępów wybranych istotnych projektów inwestycyjnych, mających na celu budowę przemysłowych instalacji dekompozycji metanu (gazu ziemnego). Opisano rodzaj zastosowanej metody pirolizy przez każdą z firm prowadzących inwestycję w tym zakresie. Obecnie, według wiedzy autorów, żadna z instalacji nie produkuje wodoru metodą pirolizy metanu w skali przemysłowej, największych postępów dokonały firmy BASF, Hypro, Hazar i Gazprom.

Wrocław 65+. Samorządowe, pozarządowe, komercyjne, kościelne i inne wrocławskie społeczne inicjatywy na rzecz seniorów
Authors: Sanecka Anna
Published: June 2023

Starzenie się społeczeństwa powoduje, że coraz więcej instytucji i firm przygotowuje oferty dedykowane seniorom. Dotyczy to zarówno instytucji samorządowych, jak też naukowych, kościelnych czy organizacji pozarządowych. Wrocław chce podkreślać swoją wyjątkowość na różnych polach działalności społecznej. Władze miasta i wrocławianie lubią, gdy zauważa się młodość czy wielokulturowość Wrocławia. Nie dziwi więc też, że włodarze starają się, aby miasto było postrzegane jako „przyjazne seniorom”. Artykuł nie jest głosem „za” lub „przeciw” temu twierdzeniu, przedstawia natomiast część oferty, kierowanej we Wrocławiu do jego starszych mieszkańców i zwraca uwagę na pewne cechy charakterystyczne dla prezentowanych inicjatyw oraz wynikające z tego zagrożenia.
Przygotowanie do późnej dorosłości w „nurcie edukacyjnego życia”. Millenialsi o planach uczenia się w starości
Authors: Konieczna-Woźniak Renata
Published: June 2023

Artykuł koncentruje się na problemach przygotowania ludzi młodych do dorosłości (zwłaszcza późnej) oraz rosnącej przepaści międzygeneracyjnej między pokoleniami Baby boomers i X a pokoleniem millenialsów (inaczej Y). Szukanie płaszczyzny porozumienia, łączącej ludzi młodszych i starszych jest wyzwaniem dla środowiska andragogów i gerontologów. Przestrzenią współpracy może być uczenie się w ciągu całego życia, zgodnie z ideą LLL. W tekście zostały opisane i przeanalizowane plany uczenia się młodych ludzi w ich starości, szczególnie w obszarze edukacji nieformalnej. Milenialsi planują kontynuować dotychczasową edukację, rozwijać pasje i zainteresowania oraz zajmować się tym, na co wcześniej nie mieli czasu. Rozwój ich dorosłego życia ma następować za sprawą podróży, czytelnictwa, aktywności sportowo-rekreacyjnej i wielu innych zajęć. Uczenie się w ciągu całego życia, oprócz realizacji zróżnicowanych potrzeb edukacyjnych, to również uczenie się samej dorosłości na każdym jej etapie. Można uznać je za zadanie rozwojowe niezależne od wieku.
Wyznaczanie maksymalnych parametrów fizjologicznych serca kobiet podczas przejścia od młodości do wieku starszego
Authors: Szubert Józef , Ziółkowski Włodzimierz , Szymańska-Paszczuk Alicja , Wieczorek Wojciech , Szubert Marietta
Published: June 2023

Podczas przejścia od młodości do wieku starszego maksymalne parametry fizjologiczne serca kobiet ulegają zmniejszeniu. Na podstawie światowych danych doświadczalnych, dotyczących badań przekrojowych i longitudinalnych zmian maksymalnych parametrów fizjologicznych serca kobiet w procesie starzenia się, stosując analizę matematyczną oraz modelowanie matematyczne i symulację komputerową, opracowano innowacyjne, kompleksowe i wiarygodne metody wyznaczania maksymalnych parametrów fizjologicznych serca kobiet: rzutu minutowego serca (COmax), częstości pracy serca (HRmax), objętości wyrzutowej serca (SVmax), różnicy tętniczo-żylnej wysycenia krwi tlenem (AVDmax) oraz pułapu tlenowego (Vo2max). Opracowane metody pozwalają każdy maksymalny parametr fizjologiczny serca dla dużej i przeciętnej wydolności kobiet przedstawić: graficznie (za pomocą wykresu), analitycznie (za pomocą równania matematycznego) oraz tabelarycznie. Takie opracowanie maksymalnych parametrów fizjologicznych serca kobiet pozwala dla dowolnego wieku i rozpatrywanej wydolności fizycznej wyznaczyć w przekroju poprzecznym wszystkie maksymalne parametry serca: COmax, HRmax, SVmax, AVDmax oraz Vo2max.

Tratado de defensa de la libre competencia : estudio exegético del D.L.701. Legislación, doctrina y jurisprudencia regulatoria de la libre competencia
Authors: Flint Blanck Pinkas
Published: June 2023

El presente trabajo de investigación está dividido en 6 capítulos los que tienen una secuencia lógica y sistemática. La obra se inicia con el marco económico del derecho de la competencia y culmina con los lineamientos metodológicos para resolver los problemas derivados de las conductas restrictivas al comercio. El primer capítulo explica los conceptos fundamentales del análisis económico del derecho y el modelo de mercado perfecto e imperfecto, tratando en este último los conceptos de monopolio, oligopolio y cárteles. Luego se aborda el mercado relevante, el poder de mercado, la posición de dominio y el rol del Estado en el diseño de las políticas de competencia. El estudio de la libre competencia demanda un profundo conocimiento micro y macroeconómico, sustento de la racionalidad de los órganos reguladores y de los tribunales que deben enfrentar los casos de defensa de la libre competencia. El segundo capítulo de la obra se aboca al tratamiento exegético del Decreto Legislativo 701, con especial énfasis en las figuras del abuso de posición monopólica y de las prácticas restrictivas. El estudio exegético comprende tanto los aspectos sustantivos como los procedimentales, así como lineamientos metodológicos desarrollados por la doctrina para el análisis de las diferentes conductas bajo estudio. El tercer capítulo comprende el estudio de la legislación comparada. En este se revisan los tratados de carácter multilateral, de aplicación en mercados ampliados y las legislaciones nacionales latinoamericanas. La legislación de cada país ha sido descrita en 3 niveles, a saber: Marco constitucional, legislación protectora de la libre competencia y legislación penal. El cuarto capítulo describe la línea jurisprudencial del Indecopi. El Juez Holmes, vocal de la Corte Suprema americana, señalaba que debíamos entender por derecho aquello que real y efectivamente hacían las Cortes y no lo que se encontraba en los textos. Este concepto es totalmente pertinente en una disciplina en permanente formación como es la normatividad de defensa de la libre competencia. Por ello se consigna las decisiones del Indecopi en base a un orden temático. No menos importante por su naturaleza obligatoria son los precedentes incluidos. El quinto capítulo es una profunda reflexión sobre la revolución en la materia a raíz de los cambios tecnológicos del siglo XXI. Se analiza los desafíos a la disciplina creados por las nuevas modalidades del comercio mundial, como la globalización, la cooperación competitiva y el efecto red. El sexto capítulo comprende los lineamientos doctrinarios desarrollados por los órganos administrativos y judiciales americanos y europeos para el análisis de conductas restrictivas y cambios en la estructura de mercado.
El Estado constitucional
Authors: Häberle Peter
Published: June 2023

El presente libro incorpora diversas nociones, entre otras, la del tipo de Estado constitucional, que se compone de elementos ideales y reales que apuntan tanto a una situación óptima de lo que debe ser, como a una situación posible de lo que es: la dignidad humana como premisa, realizada a partir de la cultura de un pueblo y de los derechos universales de la humanidad. Aunado a lo anterior se encuentra el principio de la soberanía popular en cuanto fórmula que caracteriza la unión renovada constantemente en la voluntad yen la responsabilidad pública; lo mismo que la Constitución como contrato, en cuyo marco son posibles y necesarios fines educativos y valores orientadores. También se analiza el principio de la división de poderes tanto en sentido estricto, relativo al Estado, como en el sentido amplio del pluralismo; los principios del Estado de derecho y el Estado social, lo mismo que el principio del Estado de cultura abierto; las garantías de los derechos fundamentales y la independencia de la jurisdicción. En fin, todo esto se incorpora en una democracia ciudadana constituida por el principio del pluralismo.

Pensiones : reforma y jurisprudencia : el DL 20530 y la jurisprudencia del Tribunal Constitucional
Authors: Neves Mujica Javier
Published: June 2023

La reforma constitucional en materia pensionaria cerró definitivamente el acceso de nuevos trabajadores al cuestionado régimen del Decreto Ley 20530 y dictó nuevas reglas para quienes ya pertenecían a él. Además, explicitó el criterio sobre vigencia de las normas en el tiempo que debe regir en todo nuestro ordenamiento. En este libro, el lector encontrará una revisión de los antecedentes de dicha reforma, así como de sus fundamentos y contenido. Se reseñan los principales pronunciamientos de nuestro Tribunal Constitucional sobre las normas previas y las de la reforma misma, y se hace lo propio con los emanados de la Corte y la Comisión Interamericana de Derechos Humanos. Asimismo, se analiza si las medidas adoptadas por la reforma hubieran podido plasmarse en el plano legislativo o se requería una modificación constitucional. Por último, se estudia los límites fijados por los organismos jurisdiccionales internos e internacionales a los cambios efectuados.

Notes on Assessment of Cultural Significance of the 18th-Century Old Mosque: A Case Study of the Al-Anwar Angke Mosque Jakarta
Authors: Aziz Atie Ernawati , Martokusumo Widjaja
Published: June 2023

This paper discusses the assessment process of the cultural significance of the Al-Anwar Angke Mosque in Jakarta. The mosque has been designated as an important cultural heritage, in which architectural, historical, and sociocultural values are explicitly demonstrated. Furthermore, the mosque was also considered a symbol of the diverse community in Batavia. However, the 18th-century mosque has undergone physical (including its details and ornaments) and environmental changes due to sociocultural, economic, and political dynamics. Therefore, continuous monitoring is essential to protect historic buildings, and cultural heritage values should be assessed periodically. The assessment of cultural significance includes aesthetic, historical, scientific, sociocultural, and spiritual criteria. Data collection and analysis are based on observation, interviews, and related literature. Furthermore, some critical notes indicate that assessment must be performed regularly and continuously. Thus, such an assessment is required to understand its values and unique artefacts. However, rather than determine the role of the Angke Mosque within its ever-changing context. As pointed out in the cultural significance assessment process, the article reveals the importance of recording and digitizing knowledge to comprehend the past, present, and future. Moreover, the appreciation might be understood differently due to the current urban dynamic. The assessment of the cultural significance of the Angke Mosque needs to accommodate community participation and a multidisciplinary approach to understanding architectural heritage, driven by the paradigm shift from a physical-based to a value-based system.
Exploring Islamic Vision on the Environmental Architecture of Traditional Javanese Landscape: Study of Thematic Tafseer Perspective
Authors: Fajariyah Lukman , Halim Abdul , Rohman Nur , Anwar Mokhamad Zainal , Zulhasmi Abraham Zakky
Published: June 2023

This article examines and explores Islamic visions of environmental architecture and traditional Javanese houses (joglo) from the Qur'anic perspective. This qualitative research with a descriptive method seeks to analyse the values and Islamic vision of the Joglo house architecture by exploring several data sources, both field data and literature data. The results of this study indicate that the architectural elements of the joglo house contain philosophical ideas that are relevant to the Islamic visions in the Qur'an, such as; pendapa (containing the philosophical meaning of the openness principle), pringgitan (principle of equality), dalem (principle of privacy), senthong (principle of respect), gandok (principle of food security), and pawon (use of firewood) as for the suitability of philosophical ideas with the Islamic vision in the architectural elements of the environment, namely sawo (containing the philosophical meaning of the goodness principle), jambu dersono (the principle of sharing), belimbing lingsir (the principle of remembering God), papaya (the principle of self-introspection), and beringin (the principle of knowing the origin). In short, the joglo house building reflects a house that can adapt to the environment and nature. Therefore, joglo is a representation of house architecture that can combine natural elements that are outward and inward, thus creating a comprehensive and balanced religious value.

Authors: Musa Yang Haziqah , Yusuf Adibah , Utaberta Nangkula , Usman Ismar M. S. , Wardhana Mahendra
Published: June 2023

A shopping mall refers to a structure with several retail establishments managed as a single property that offers various products and services. It has become essential to the functioning of contemporary society, particularly for residents of urban and suburban areas. However, concerns or issues regarding facilities and services in shopping malls continue to surface even today. Past studies have suggested that facility management is a best practice for overcoming management and operation issues. It also aligns with the Islamic principle as it is beneficial knowledge relevant to the modern management approach. Therefore, this paper seeks to comprehend the potential facility management approach to shopping mall management. The main objective of this study is to emphasize the importance of facility management in shopping malls by evaluating consumer satisfaction. A survey is conducted with a total sample of 200 respondents based on three facility management maintenance characteristics: functional, technical, and image. One of the reputable shopping malls in Johor Bahru is selected for this study because it attracts numerous visitors from throughout Johor Bahru. The results show that most of the visitors are pleased and satisfied with all three aspects from the dimension of facility management.
The Islamic Architectural Monuments in Kosovo During XVI – XVIII Centuries
Authors: Zeneli Fidan
Published: June 2023

This article aims to shed light on the construction of architectural monuments in Kosovo as early as the XVI-XVIII centuries, especially Islamic architecture. This style of construction, influenced by the eastern part of the continent, had its own construction features, which set it apart from other constructions built before Islam. Those features reached Albanian areas after the Ottoman Empire conquered them. This type of architecture expressed religious aspects in mosques and prayer facilities, but bridges, markets, shrines, and other objects were also constructed. The research results indicated that Ottoman architectural features were influenced by local traditional elements. A specific model was produced and used in all Albanian areas under Ottoman rule. Secondly, over time numerous objects were built following this model. As a result, cities and lives were changed. A comparative research methodology besides analysis and synthesis was followed to elaborate this paper, using relevant literature.
The Coping Strategies of Intimate Partner Violence Survivors
Authors: Damra Jalal K. , Abujilban Sanaa
Published: June 2023

This study investigates the prevalence of coping strategies (CSs) among women with intimate partner violence (IPV) experience in Jordan and the relationships between types of IPV, demographic factors, and CSs (problem-focused strategies [PFS], emotion-focused strategies [EFS], and avoidance-oriented strategies [AOS]) that they use. It also explores the predicting factors affecting the types of CSs applied. Eighty-nine Jordanian and Syrian women who experienced abuse were involved in the study. The data were collected using the revised version of the Conflict Tactics Scale (Straus et al., 1996) and the Coping Inventory for Stressful Situations: Situation-Specific Scale (Endler & Parker, 1990). The results indicated a moderate use of PFS and EFS and mid-to-high use of AOS. The psychological aggression and physical violence, injuries, help-seeking, education level, children, and marriage duration were significantly related to the use of all three strategies. Employment status, age, legal residency, and negotiation skills had no significant relationships with the used CSs. The regression results indicated that children, psychological aggression, and asking for help predicted 49% and 41% of the covariance of using PFS and EFS, respectively, while the number of children, physical violence, and injuries predicted 81% of the covariance of using AOS. The study suggested the importance of supportive social services for women with IPV experiences. The clinical practice implications for helping women who experience IPV and future research were discussed.
A Theory for Prelicensure Nursing Student Satisfaction With Clinical Learning Experiences: An Integrative Review
Authors: Welch Susan
Published: June 2023

The satisfaction of prelicensure nursing students is a prominent and essential component of programmatic outcome data for accreditation agencies and ongoing program improvement. Nursing student satisfaction correlates with student retention, graduation rates, and future employment and can assist nurse educators in determining if supportive clinical experiences exist. However, nursing students report moderate-to-high levels of clinical stress within clinical environments, impacting both satisfaction and future role preparation. Additional research is necessary regarding prelicensure nursing student satisfaction within their clinical environments, yet a theoretical gap exists to guide such future research. The purpose of this integrative review was twofold. First, perform an integrative review to explore factors associated with prelicensure undergraduate nursing student satisfaction in clinical learning experiences. Second, provide a theory to guide future research regarding the topic.

Authors: Musa Ahmad S , Abdalrahim Asem , Alkhawaldeh Abdullah , Suliman Mohammad , Al Qadire Mohammad I , AlBashtawy Mohammed , AlAzzam Manar
Published: June 2023

Background and Purpose:No valid and reliable instrument exists in Arabic to measure the spiritual perspectives of Arab Muslims and Christians. This study translated the Spiritual Perspective Scale (SPS; Reed, 1987) into Arabic and examined its psychometric properties.Methods:The Arabic SPS was tested in a convenience sample of 206 Jordanian Christians and 182 Jordanian Muslim undergraduate nurses. Correlational and exploratory factor analysis were used.Results:For both sample groups, the factor analysis supported a clear two-factor structure for the Arabic SPS. A significant moderate positive correlation between the spiritual perspectives and religiosity was in the expected direction. The internal consistency reliability of the Arabic SPS was high. This study revealed that the Arabic SPS is a valid and reliable instrument to measure spiritual perspectives among Jordanian Muslim student nurses and adult Christians.Implications for Practice:Developing an Arabic version of the SPS exhibited good evidence of validity and reliability is important because it contributes to the evaluation of the spiritual behaviors and spiritual values and beliefs of Arab nurses and their patients. It also opens the way for comparison and transcultural studies regarding individual’s spiritual perspectives.

Entre los factores que afectan estos errores se destacan la falta de dedicación, su desconocimiento de los recursos necesarios (enciclopedias, diccionarios, etc.).Por lo cual, los estudiantes necesitan mejorar sus competencias traductoras, sobre todo, la competencia lingüística. Finalmente, esperamos ofrecer algunos resultados que podrían servir para la formación de traductores en las clases de traducción del español al árabe, porque este proceso todavía afronta diferentes retos.
Preguntó (que) si qué quería: si como operador interrogativo en español vernáculo
Authors: Del Barrio de la Rosa Florencio
Published: June 2023

Este artículo estudia la sintaxis de las interrogativas indirectas en algunas variedades vernáculas del español contemporáneo. Estas estructuras se caracterizan por el empleo antinormativo de la conjunción si, opcionalmente precedida de que en algunos dialectos, para introducir interrogativas parciales (me preguntó (que) si qué quería). A partir de casos extraídos del “registro coloquial escrito”, en el artículo se analizará la estructura oracional de estas secuencias y su distribución areal en el español del tercer milenio. Por más que se trate, por su génesis o por su frecuencia, de construcciones marginales, estos esquemas ponen de manifiesto la emergencia de un operador interrogativo en la configuración funcional de las interrogativas indirectas. Las conclusiones demuestran la importancia de examinar las variedades subestándares del español para evidenciar las categorías encubiertas de su gramática y revisar desde otra óptica los análisis recibidos
Women's Empowerment: Evidence from the Corn-Tortilla Value Chain in the Central Valley’s Region and the Isthmus of Tehuantepec, Oaxaca, Mexico.
Authors: Sánchez-Soriano Marbella , Toledo-López Arcelia , Acevedo-Martínez Jorge Antonio , Cruz-Cabrera Blasa Celerina
Published: June 2023

This article explores the level of Women’s Empowerment (W’E) from six empowerment domains: decision-making, autonomy, access and control of resources, community participation, and participation in business management, within the context of the corn-tortilla value chain. A semi-structured questionnaire was used to collect data through the survey method and participant observation. The sample consisted of 136 women producers from two municipalities, 67 from Santa María Xadani in the Isthmus of Tehuantepec and 69 from San Antonio de la Cal in the Central Valleys of Oaxaca, Mexico. The results highlight that women exercise five of the six explored domains of empowerment, two with high levels and three with medium levels of empowerment. The women’s income from selling their corn tortillas is used to buy food, raw materials, and health services. Much of their time is spent on corn tortilla production and marketing, and household activities. Finally, this study makes implications for public policy to contribute with the generation of strategies that raise the levels of W’E in agrifood systems in rural contexts.

The Concept of Awkward Powers in Foreign Relations
Authors: Pikalo Jernej , Durnik Mitja
Published: June 2023

This paper addresses a specific phenomenon concerning power concepts in‎ Canadian and EU foreign policies. As is widely known, the liberal-democratic ‎platform has dominated global relations after the end of the Cold War. Implemented ‎power approaches are studied from theoretical perspectives of liberalism/‎constructivism standpoints and their realist critique. Canada has been ‎presented mostly as a middle power in international relations trying to find‎ its specific role as a mediator and balancer among superpowers. On the other ‎hand, the EU is classified predominantly as a normative power with tendencies ‎to act as a great power from some point of view. In the paper, we analyse ‎both entities through the recent concept of ‘awkward power’, whereby states ‎have a so-called “dubious character”, acting in-between the potential of great‎ and middle powers.‎
On the Rigidity of the Sasakian Structure and Characterization of Cosymplectic Manifolds
Authors: Patra Dhriti Sundar , Rovenski Vladimir
Published: June 2023

We introduce new metric structures on a smooth manifold (called “weak" structures) that generalize the almost contact, Sasakian, cosymplectic, etc. metric structures (φ,ξ,η,g) and allow us to take a fresh look at the classical theory and find new applications. This assertion is illustrated by generalizing several well-known results. It is proved that any Sasakian structure is rigid, i.e., our weak Sasakian structure is homothetically equivalent to a Sasakian structure. It is shown that a weak almost contact structure with parallel tensor φ is a weak cosymplectic structure and an example of such a structure on the product of manifolds is given. Conditions are found under which a vector field is a weak contact vector field.
Pattern Formation in a Predator-Prey Model with Allee Effect and Hyperbolic Mortality on Multiplex Networks
Authors: Shi Lei , Zhou Jiaying , Ye Yong
Published: June 2023

With the rapid development of network science, Turing pattern on complex networks has attracted extensive attention from researchers. In this paper, we focus on spatial patterns in multiplex ER (Erdös-Rényi) random networks, taking the predator-prey model with Allee effect and hyperbolic mortality as an example. In theory, the threshold condition for generating Turing pattern is given using the Turing instability theory of multiplex networks. Numerically, we design relevant experiments to explore the impact of network topology on Turing pattern. The factors considered include model parameters, diffusion rate, average degree of the network, and differences in the average degree of different layers. The results indicate that the importance of diffusion rate and network average degree for Turing pattern is affirmed on the single-layer network. For multiplex networks, the differentiation of average degrees in different layers controls the generation of Turing pattern, which is not affected by the diffusion rates of the two populations. More interestingly, we observe the switching of Turing pattern and spatiotemporal pattern. We believe that these findings contribute to a better understanding of self-organization on complex networks.

Drafting formations have been long recognized as highly effective for reducing drag and enhancing athletic performance, particularly in race walking events. The precise spacing and positioning of the race walkers are critical to optimizing the effectiveness of drafting. In this study, the drag reduction of 15 drafting formations is investigated using wind-tunnel experiments and CFD numerical simulations. The results show excellent consistency in drag reduction rate between the two methods, with differences being within 10%. This can be attributed to spacing replacing body shape differences as the primary factor influencing drag reduction. Optimal double, triple, and quadruple drafting formations produce the same results in both wind-tunnel experiments and CFD simulation, resulting in drag reductions of 67%, 66%, and 81% (wind-tunnel) and 65%, 72%, and 85% (CFD). The sources of drag differences in the two methods are discussed from various aspects. The flow field obtained through CFD analysis is used to examine the mechanism of drag reduction, revealing that drafting formations have a significant shielding effect on incoming air, which reduces the number and speed of airflow impacting the core race walker. This shielding effect is identified as the primary cause of drag reduction. Using an empirical model for mechanical power output, optimal double, triple, and quadruple drafting formations enhance sport economy (4.4-5.7%), speed (3.61-4.67%), and performance (173.8-223.3s) compared to race walking alone. The findings can serve as a reference for race walkers' positioning strategy and provide insights for considering drafting formations in various running events.
How was the “Chicken and Egg Relationship” between Gene and Protein formed?
Authors: Ikehara Kenji
Published: June 2023

It has not been reasonably explained still now, how the “chicken and egg relationship” between gene and protein was formed, although RNA world hypothesis was proposed to aim at explaining formation process of the relationship about 40 years ago. On the other hand, GADV hypothesis advocates that life emerged after five members of the fundamental life system; cell structure, metabolism, tRNA, genetic code and gene, were piled up one by one onto immature [GADV]-proteins, which were produced by random joining of [GADV]-amino acids on the primitive Earth. Furthermore, formation process of the first (GNC)n RNA gene encoding a mature [GADV]-protein can be also reasonably explained according to the hypothesis as follows. Double-stranded (ds)-(GNC)n RNA could be produced by complementary strand synthesis of a single-stranded (ss)-(GNC)n RNA, which was formed by random joining of GNC anticodons carried by four types of AntiC-SL tRNAs. Successively, the first (GNC)n RNA gene was generated upon maturation of an immature [GADV]-protein, which was produced through expression of codon sequence on one strand of ds-(GNC)n RNA, as accumulating necessary base substitutions and raising a weak catalytic activity of the immature protein to a more active state. It is considered that, consequently, a gene encoding a mature protein, which has the “chicken and egg relationship”, was generated for the first time. Therefore, it can be concluded that the “chicken and egg relationship” was built not by formation of either one, gene or protein, but by maturation of an immature gene, which was lead by improvement of catalytic activity of an immature protein. That is, it can be concluded that the reason, why it was unable to give an answer to the question on the formation process of the “chicken-egg relationship” thus far, is because it was an unanswered question.
Spherically Symmetric C3 Matching in General Relativity
Authors: Quevedo Hernando
Published: June 2023

We study the problem of matching interior and exterior solutions of Einstein’s equations along a particular hypersuface. We present the main aspects of the C3 matching approach that involves third-order derivatives of the corresponding metric tensors in contrast to the standard matching procedures known in general relativity, which impose conditions on the second-order derivatives only. The C3 alternative approach does not depend on coordinates and allows us to determine the matching surface by using the invariant properties of the eigenvalues of the curvature tensor.
Farmers’ Perception about Climate Change and Variability, and Its Impact on Agriculture: In the Case of Dorebafana District, Sidama Region of Ethiopia.
Authors: Wola Aklilu Wodebo
Published: June 2023

Rain-fed agriculture remains the source of employment for a majority of Ethiopian population, particularly in Dorebafana District, where annual rainfall is low. Perception of climate change and variability supported by local knowledge has helped to advance understanding of climate change and its impacts on agricultural land-use systems. Thus, the overall objective of this study was assessing farmers’ perception of climate change and variability and its impact on agriculture in Umbulo Kajima and Lebu Koromo kebeles of Dorebafana, Sidama region of Ethiopia. A total of 88 sample households from the two kebeles, farmers’ perception were compared with historical climatic data from the closest weather station of the study area. The household survey, focus group discussions and field observation were used as primary data sources in the study area. The data was analyzed by using descriptive statics in Statistical Package for the Social Sciences and multinomial logistic regression model. As data showed, there was the declining and high variability of rainfall in the last three decades In addition, the maximum annual rainfall was observed in 1998, 1755.4 mm and the lowest annual rainfall was recorded in 2015, 537.4 mm in the study area. The focus group discussions and key informant interviews further supported the idea that rainfall in the research area has been falling and very variable over the previous three decades. The finding showed that, temperature increased by 0.1oC over the previous three decade, and socioeconomic factors such sex, age, farming experience, knowledge of the climate, market access, and agro-ecology had an impact on farmers' perceptions of climate change and its impact in agriculture. Therefore awareness creation, increase educational level, sharing experience, scaling up best practice and using new technologies are the best alternatives to minimize the adverse effects of climate change.

Authors: Jaroni Divya , Litt Pushpinder Kaur , Bule Punya , Rumbaugh Kaylee Marie
Published: June 2023

(1) Background: Formation of biofilms on food-contact surfaces by Shiga-toxigenic Escherichia coli (STEC) can pose a significant challenge to the food industry, making conventional control-methods insufficient. Targeted use of bacteriophages to disrupt these biofilms could reduce this problem. Previously isolated and characterized bacteriophages (n=52) were evaluated against STEC biofilms in-vitro and on food-contact surfaces. (2) Methods: Phage-treatments (9 logs PFU/ml), in phosphate-buffered-saline, were used individually or as cocktails. Biofilms of STEC (O157, O26, O45, O103, O111, O121, and O145) were formed in 96-well micro-titer plates (7 logs CFU/ml; 24 h) or on stainless-steel (SS) and high-density-polyethylene (HDPE) coupons (9 logs CFU/cm2; 7 h), followed by phage-treatment. Biofilm-disruption was measured in-vitro at 0, 3, and 6 h as a change in optical-density (A595). Coupons were treated with STEC-serotype-specific phage-cocktails or a 21-phage cocktail (3 phages/serotype) for 0, 3, 6 and 16 h and surviving STEC populations enumerated. (3) Results: Of the 52 pages, 77% showed STEC-biofilm disruption in-vitro. Serotype-specific phage-treatments reduced pathogen population within the biofilms by 1.9-4.1 and 2.3-5.6 logs CFU/cm2, while the 21-pahge cocktail reduced it by 4.0 and 4.8 logs CFU/cm2 on SS and HDPE, respectively. (4) Conclusions: Bacteriophages can be used to reduce STEC and their biofilms.

Published: June 2023

Since the 20th century, Japan has experienced a period of very rapid urbanization. Cities have experienced substantial densification and expansion, resulting in gradually elevated flood risk. Urban flooding has also occurred in most large cities in Japan, particularly in Tokyo. In response to this growing problem, much effort and resources have been spent on research and development aimed at understanding, simulating, and managing urban flood risk in Japan. The objective of this review is to summarize, discuss and share key outputs from some of the main research directions in this field, significant parts of which have been uniquely developed in Japan and only published in Japanese. After a general introduction to urban runoff modelling, in the next section, key historical works in Japan are summarized, followed by a description of the situation in Japan with respect to observations of precipitation and water level. Then, the storage function model approach is reviewed, including an extension to urban basins, as well as recent experiments with AI-based emulation in Japanese basins. Subsequently, we review the prospects of detailed hydrodynamic modelling involving high-resolution, vector-based Geographical Information System (GIS) data for the optimal description of the urban environment with applications in Tokyo. We conclude the paper with some future prospects related to urban flood risk modelling and assessment in Japan.
Deep Dive Into the DNA Polymerase Through Insilico Analysis: An Information to Get Better PCR Enzyme From the Ancient One
Authors: Mitra Debanjan
Published: June 2023

The polymerase chain reaction (PCR) is a widely used technique in the biosciences and has become increasingly popular in recent years. One of the key elements of this technique is the use of a DNA polymerase that is heat-stable and retains fidelity during the process. To this end, archaeal Fam-ily-B DNA polymerases are preferred due to their high thermostability and fidelity. In particular, the DNA polymerase from Thermus aquaticus (Taq DNApol) is widely utilized in PCR procedures. In this work, a novel in-silico structure-based methodology was employed to examine the most heat-tolerant DNA polymerase available. In spite of this, Thermococcus kodakarensis and Geobacillus stearothermophilus DNApol are more stable and heat-tolerant DNApols due to their high number of intra-protein interactions. Variations in the content of polar amino acids also played a significant role in the increase in heat stability. A further factor contributing to the stability of proteins is the stabilization of helix in secondary structure through the use of charged amino acids. DNApol from these organisms has been shown to be suitable for use in PCR, as well as in other biological processes able to withstand high temperatures. In this study, it has been demonstrated that im-provements in PCR performance can be easily obtained by blending elements from closely related archaeal polymerases, a strategy that may, in the future, be extended to other archaeal polymer-ases. This approach allowed for a comprehensive analysis of the enzyme's thermal stability and fidelity, leading to an improved understanding of the polymerase's properties and potential ap-plications
