Pengaruh Ekstrak Etanol Buah Takokak (Solanum torvum S.) terhadap Jumlah Folikel Ovarium dan Bobot Uterus pada Mencit Betina (Mus musculus L.)
Authors: Kurniati Reni , Regina Yudith Simanungkalit  , Retno Aryani  
Published: January 2025

Takokak merupakan tumbuhan yang berpotensi sebagai agen antifertilitas jantan, namun sampai saat ini belum ada penelitian yang menyatakan bahwa buah takokak ini dapat berpengaruh pada organ reproduksi mencit betina khususnya ovarium dan uterus. Penelitian ini bertujuan untuk mengetahui potensi buah takokak sebagai agen antifertilitas betina. Mencit betina 16 ekor dibagi 4 kelompok, kelompok kontrol diberi Na CMC 0,5%, kelompok perlakuan 1, 2, dan 3 diberi ekstrak etanol buah takokak dengan dosis 250 mg/kgBB, 500 mg/kgBB, dan 1000 mg/kgBB dalam pelarut Na CMC 0,5%. Mencit yang telah diaklimatisasi selama 7 hari kemudian ditimbang berat awalnya lalu diberikan ekstrak pada masing-masing perlakuan 1 kali sehari pukul 16.00 WITA selama 28 hari. Ekstrak buah takokak diberikan secara oral dengan metode gavage. Data dianalisis dengan ANOVA dan uji lanjut Duncan. Berdasarkan hasil penelitian dapat disimpulkan bahwa ekstrak etanol buah takokak mampu menurunkan jumlah folikel primer,sekunder, tersier dan menyebabkan atrofi uterus mencit sehingga berpotensi sebagai agen antifertilitas untuk betina.

Penerimaan terhadap teori evolusi merupakan salah satu isu menantang dalam dunia Pendidikan di Indonesia. Penelitian ini bertujuan untuk mendeskripsikan persepsi awal mahasiswa terkait teori evolusi sebelum mempelajari mata kuliah evolusi. Pada penelitian melibatkan 99 orang mahasiswa Pendidikan Biologi sebagai subjek penelitian. Data dikumpulkan melalui angket berisi open-ended dan closed-ended questions. Ditemukan bahwa 54,6% mahasiswa percaya dengan teori evolusi, 41,4% ragu-ragu dan 4% tidak percaya. Persepsi mahasiswa yang mengatakan ragu-ragu dan tidak percaya teori evolusi karena (1) menyadari kurangnya pemahaman mereka tentang evolusi; (2) teori evolusi bertentangan dengan keyakinan mereka; (3) adanya keraguan terhadap teori Darwin; (4) bukti terkait evolusi masih belum cukup memadai atau kurang meyakinkan. Adapun persepsi mahasiswa yang menerima teori evolusi dengan landasan sebagai berikut (1) evolusi dapat dibuktikan melalui bukti ilmiah; (2) mereka harus mampu menilai teori evolusi secara ilmiah dan terlepas dari perspektif agama; (3) menyadari bahwa teori evolusi perlu ditinjau dengan berbagai informasi dari berbagai perspektif. Temuan ini dapat dijadikan acuan serta memberikan rekomendasi pendekatan bagi dosen dan para pendidik untuk melaksanakan pembelajaran evolusi.

André Du Ryer en español: una retraducción del Alcorán inédita
Authors: Arias Torres Juan Pablo 
Published: January 2025

Durante el siglo XIX y principios del XX fue una constante la traducción del Alcorán al español no desde el original árabe sino a partir de versiones a otras lenguas, especialmente, la francesa. Traducciones galas consagradas como las de Claude Savary o, sobre todo, la de Albin de Biberstein Kazimirski fueron objeto de traducción y reedición en repetidas ocasiones a nuestra lengua. Llamaba la atención, sin embargo, la casi total ausencia de referencias en nuestra lengua a L’Alcoran de Mahomet de André Du Ryer, versión de gran éxito y difusión en Europa desde su publicación en 1647. Ese vacío en la historia de la traducción del texto sagrado islámico al español se completa con el hallazgo de la traducción castellana anónima de esa versión contenida en los mss. II/609, II/610 y II/3544 de la Biblioteca Real de Madrid que aquí presentamos, caracterizada por una fidelidad absoluta al original francés.
LA BÚSQUEDA DE BUEN VIVIR COMO MANIFESTACIÓN DE AGENCIA COLECTIVA E IDENTIDAD PROFESIONAL: UNA EXPLORACIÓN TEÓRICA DEL MOVIMIENTO DOCENTE CON FOCO EN CHILE Y LATINOAMÉRICA
Authors: Torres Betzabe , Avilés Nidia , León Violeta 
Published: January 2025

Este artículo propone cómo la búsqueda por el bienestar en el trabajo docente es una expresión agéntica que no es una cuestión individual sino colectiva. Así, conceptualizamos agencia y bienestar desde una perspectiva latinoamérica, donde se entenderá agencia como todo aquello que se realiza en el presente, informado por historias pasadas e inspirado en una esperanza futura de que las cosas sí pueden ser de otra manera. Lo anterior, fundado en las ideas de Paulo Freire y la filosofía del Buen Vivir, desde donde entenderemos a la profesión docente como dialógica y colectiva.
El concepto de agencia nos permite ver el trabajo y profesión docente como transformadora y productora de conocimiento. El concepto de bienestar, entendido desde la filosofía del buen vivir, plantea que no se puede aspirar al bienestar individual si no existe uno colectivo.
Finalmente, exploramos cómo en Chile se han dado ciertos movimientos agénticos, por ejemplo, en la movilización docente del presente año, la cual se plantea como una lucha por avanzar hacia la reconstrucción de la educación que todos y todas merecen, lo cual, sin dudas hará eco en la región latinoamericana.

Published: January 2025

Las prácticas del Colegio Paulo Freire de San Miguel permiten observar una serie deexperiencias de las que se pueden recuperar importantes elementos para la reexión y elanálisis de un proyecto educativo heredero de la tradición freiriana, inspirado en la educación popular. Este proyecto propone un funcionamiento que aporta a la construccióny el desarrollo de espacios educativos liberadores. En ese sentido, la sistematización deexperiencias propuesta por Oscar Jara y su método de cinco pasos fueron desarrolladosy aplicados en la revisión de tres experiencias pedagógicas del Colegio Paulo Freire entrediciembre de 2018 y marzo de 2020. Esto propició una interpretación crítica, posibilitadapor el ordenamiento, la reconstrucción y la validación colectiva de los procesos vividos.A partir de un análisis teórico centrado en la dialogicidad y la horizontalidad, y una reexión aplicada a parte de los resultados de una de las experiencias sistematizadas, se avanzará en esclarecer cómo la práctica asamblearia construye horizontalidad en la línea de la aspiración político-pedagógica de promover la acción dialógica en el ámbito escolar, reemplazando y redeniendo las prácticas, los cargos, los roles y los espaciosrelacionales y decisionales.Palabras clave: dialogicidad, horizontalidad, asamblea, sistematización de experiencias.

A heat exchanger is a device for exchanging energy in the form of heat between two or more fluids of different temperatures. There are several types of heat exchangers, including a double-pipe heat exchanger. This double-pipe heat exchanger is used widely in field practice. Double pipe heat exchangers are especially suited to standard thick surfaces in fins shape so that heat transfer is increased. The research is conducted to observe how far the use of fins in double-pipe heat exchange affects its characteristics. The fins added in the study are elongated fins on the outer surface of the inner pipe. The research is carried out using the working fluid water, with cold fluid in the heat exchanger annulus. From the research carried out, it can be said that heat transfer increases with the addition of fins, namely around 15%, but the pressure drop also increases, i.e., around 904 Pa (29%), compared to double pipe heat exchangers without fins. Research has also shown that the highest effectiveness of double pipe finned heat exchanger is 0.28, while without fins, it is 0.19.
Tethered cord syndrome in patients with myelomeningocele: Presentation of 3 cases, technical note on re-anchoring without dural opening
Authors: Basilotta Marquez Yamila , Pirozzi Chiusa Christian , Pérez Zabala Joaquín , Argañaraz Romina 
Published: January 2025

Background:
Following myelomeningocele (MMC) repair, 10-30% of patients develop tethered cord syndrome (TCS). Surgical intervention is critical to reverse the stretching of the spinal cord. Here, we describe a technique for spinal cord untethering without dural opening in these patients.

Methods:
Three patients underwent spinal cord untethering without dural opening. The surgical technique involved reopening the previous incision and dissecting the scar tissue attached to the dura. A Spongostan sponge was inserted, and lateral sutures were placed between the dural sac and the adjacent muscles. Clinical outcomes, imaging findings, and urodynamic results were evaluated postoperatively.

Results:
The technique demonstrated positive outcomes in all three cases. Patients showed symptom improvement, better positioning of the spinal cord on imaging studies, and enhanced bladder function on urodynamic evaluations.

Conclusion:
Spinal cord re-untethering without dural opening may be a viable surgical option for selected patients with MMC, offering favorable outcomes with reduced risk.

“Street art represents the voice of the periphery” — Alexandra Henry at Ljubljana Street Art Festival, 2022
The notion of the periphery usually serves as a starting point for critically examining and problematizing the contemporary dynamics of capitalism, ranging from global inequality to extractivism. This concept, however, may be also extended beyond the field of political-economic analysis (Wallerstein 2004) to embrace other socio-cultural dimensions. As Bazzini and Puttilli (2008, p. 23) argue, the transformation of cities in postmodernity has led to the disintegration of the relationship between center and periphery, giving rise to multiple centers and multiple peripheries. Thus, these multiplying centers and peripheries are not only mere political, geographic, urbanistic tipologies—and we could add topologies—but encompass also fluid cultural and symbolic flows (ibid.; see Appadurai, 1996), making them dialogic and relational. If we are to understand peripheries relationally (cf. Massey, 1994), then at the level of the production of social space, we must highlight their dialogic, communicative, transversive power/capabilities, and the inscribed meanings that are transmitted across and through these multiple peripheries, multiple centers. One such vehicle is the artistic, artivistic and political practices within urban space encapsulated in the often contested notion of ‘street art’ and, by extension, ‘graffiti’.
Walk the Line project in Genoa:
Authors: Boero Gabriele 
Published: January 2025

The Walk the Line Street Art project, organized in the north-western Italian city of Genoa, starting from summer 2016 has brought a new face to the skyway of the city, mostly hated by both residents and tourists but strictly necessary for the city’s fluid control of the traffic flow. Working on the surface of the pillars of the skyway, the artists called by the curators have been participating in a project that not only wants to embellish an infrastructural element of the city, but also wants to start a dialogue and create a link between different neighborhoods, creating a sort of open-space gallery. Furthermore, the different backgrounds of the artists who have taken part in the project raise a reflection about the dialogue between Graffiti-Writing traditions that still live today and Street Art innovations in the field of public art issues. The essay has the purpose of analyzing this kind of Street Art project, evaluating its artistic and social impact on the city, comparing it to the traditions developed by the protagonists of the Writing scene in Genoa and in northern Italy during the 1990s and the 2000s and introducing various questions about terminology.
Direzioni Coraggiose - Brave Paths
Authors: Casella Costantino , Schiavottiello Nicola 
Published: January 2025

In order to renew the subversive gesture of the first writers (such as Zephyr, Lee, Taki 109, Dondi ) it is crucial to develop the one’s practice within a constructive discourse of the common (Pani et al., 2008). Sometimes it becomes essential to intervene, to redevelop and to implement decorating paths in places where the old modules have evidently failed.
Since street art has been legally recognized, the artist-spectator relationship has become more intimate; direct, free from filters and rules imposed by society and the dominant cultures (Galal, 2009), also this can represented a great change.

Craig Castleman is the author of seminal “Getting Up: Subway Graffiti In New York” originally published by MIT press, cult book for the graffiti/street art subculture and mandatory bibliographic reference in the academic field. Advised at Columbia University by Margaret Mead, famous anthropologist known for her work on the relationship of culture and personality and Loius Forsdale that suggested: “this isn’t the time to worry about why people write and fight graffiti, because we aren’t sure yet jus what it is that they are doing. Find that out first. People can argue about what it all means later on.” We also share the room with the organisations Contorno Urbano and Indague, who developed in 2019 with Craig the Castleman Tour: a project in Spain with 16 events, an exhibition and the launch of the book Getting Up again: 40 years later, made it possible with the support of community writers in crowdfunding strategy.
Street Art & Graffiti in Belgrade: Ecological Potentials?
Authors: Tunic Srdan 
Published: January 2025

Since the emergence of the global contemporary graffiti and street art, urban spaces have become filled with a variety of techniques and art pieces, whether as a beautification method, commemorative and community art, or even activism. Ecology has also been a small part of this, with growing concern over our environment’s health (as well as our own), disappearing living species and habitats, and trying to imagine a better, less destructive humankind (see: Arrieta, 2014).

But, how can this art - based mostly on aerosol spray cans and thus not very eco-friendly - in urban spaces contribute to ecological awareness? Do nature, animal and plant motifs pave a way towards understanding the environment, or simply serve as aesthetic statements? This paper will examine these questions with the example of Belgrade, Serbia, and several local (but also global) practices. This text is based on ongoing research as part of Street Art Walks Belgrade project (STAW BLGRD) and interviews with a group of artists.

The issue examines the natural and built environment in Istanbul through the relationship between urban planning, urban space, architecture, and landscape architecture. It focuses on designs made in different parts of Istanbul between natural areas and built areas in the city.
The ex post analysis and perspectives of an Urban Creativity program between artistic requalification and social regeneration
Authors: Scardapane Silvia , Mongelli Monica 
Published: January 2025

In 2015 INWARD - National Observatory on Urban Creativity started the project “Parco dei Murales”, a process of artistic requalification and social regeneration in the Ponticelli district, the eastern part of the great city of Naples. Four years after the completion of the pictorial works, questions regarding the influence of the creative program on the urban area arise: how did these interventions generate a change in the neighborhood? What impact did they have had on the community?
Many inhabitants perceive the eastern outskirts of Naples as a marginal space of the metropolis of Southern Italy, a “liminal” area not only geographically but also socially if we think about the exposure of some segments of the population to situations of the uncertainty of the social and economic condition. It is noted that this area manifests an evident lack of services that can allow a transformation towards a condition of certainty. The artistic and social experience in the “Parco dei Murales”, was born to subvert all this and allow the external public to enter an inhabited space previously considered repulsive.
In relation to three macro-categories as Art, Social, and Promotion, we will try to answer the initial questions to investigate the positive and negative aspects of a collective program.
Through data related to the work experience collected from 2015 to 2021, to the elaboration of surveys, outputs submitted to the community, and comparisons with similar realities in Italy, we have reached a liminal moment of the work that is a moment of waiting between what has been achieved and the transformation in progress. What are future evolutions? How to envisage the extension of an urban creativity program for the social in a creative territorial system?
О РЕЧИ ЯКОБА ГЕРМАНА НА ВТОРОМ ОТКРЫТОМ ЗАСЕДАНИИ ПЕТЕРБУРГСКОЙ АКАДЕМИИ НАУК 1-ГО АВГУСТА 1726 ГОДА "О ПРОИСХОЖДЕНИИ И РАЗВИТИИ ГЕОМЕТРИИ"
Authors: СИНКЕВИЧ Г И. 
Published: January 2025

Якоб Герман (1678-1733), швейцарский математик и механик, любимый ученик Якоба Бернулли, родственник Леонарда Эйлера, был первым профессором высшей математики Петербургской академии наук. Он прибыл в Петербург 15 (26) августа11725 г. и уже 13 ноября того же года открыл первое заседании Академии докладом «О сфероидной фигуре Земли». Как известный математик, светский и разносторонне образованный человек, самый старший из собравшихся ученых, он представлял лицо Академии. К числу его обязанностей относилась честь выступать на публичных заседаниях, на которых присутствовала императрица. 1 августа 1726 г. второе публичное заседание Академии почтила Екатерина I с семьей и свитой. Герман приготовил большую речь на латыни, но из опасения утомить императрицу и придворных, сократил свое выступление. В 1728 г. эта речь была опубликована в Петербурге. Здесь мы впервые предлагаем перевод этой речи Германа «О происхождении и развитии геометрии». Эту речь можно смело назвать программной, или, как мы сейчас бы сказали, пленарной, так как она, по словам автора, раскрывает не только «начало, развитие и торжество математики», но и дает современную к тому моменту картину состояния математики, а также обрисовывает задачи в области математики и механики, стоявшие перед молодыми академиками.
Jacob Hermann (1678-1733), Swiss mathematician and mechanic, favorite student of Jacob Bernoulli, relative of Leonhard Euler, was the first professor of the St. Petersburg Academy of Sciences, arrived in St. Petersburg on August 15 (26), 1725 and already on November 13, 1725 opened the first meeting of the Academy report "On the spheroid figure of the Earth." He considered the largest luminary and the face of the young Academy as a famous mathematician, a secular and well-educated person, an oldest of the invited scientists. The honor of speaking at public meetings attended by the Empress was among his duties. On August 1, 1726, Empress Catherine I with her family and retinue attended the second public meeting of the Academy. Herman prepared a big speech, but for fear of tiring the empress and the courtiers, he shortened his speech. In 1728, this speech published in St. Petersburg. Here we offer a first translation of Hermann's speech "On the origin and development of geometry. " According to the author, it reveals not only "the beginning, development and triumph of mathematics," but also gives a contemporary (to 1726) picture of the state of mathematics, and also outlines the challenges in mathematics and mechanics facing young academics.
