Published: October 2023

Benih yang diberi perlakuan larutan etanol dengan konsentrasi yang semakin tinggi akan mengalami lebih banyak kemunduran dan viabilitasnya akan rendah. Kejadian ini mirip dengan benih yang disimpan untuk periode simpan alami yang lama. Penelitian ini bertujuan untuk membandingkan viabilitas benih dari dua varietas kedelai akibat pengusangan cepat maupun periode simpan alami. Pengusangan cepat dengan menggunakan larutan etanol 8% dengan intensitas 0, 2, ..., 12 jam. Lama penyimpanan alami yang digunakan adalah 0- 6 bulan di ruang penyimpanan bersuhu 27,3±0,9 ?C. Dua varietas benih kedelai adalah Grobogan dan Argomulyo. Viabilitas yang diukur adalah persentase kecambah normal total (KNT) dan kecepatan perkecambahan (KP), yang keduanya diamati pada setiap akhir perlakuan pengusangan cepat atau pada setiap akhir periode simpan alami. Hasil penelitian menunjukkan bahwa viabilitas benih kedua varietas kedelai, baik diukur dengan KNT maupun KP, selama penyimpanan 0 sampai 6 bulan tidak berbeda secara signifikan berdasarkan uji t-student 5% dari benih yang diamati pada perlakuan pengusangan cepat 0-12 jam dengan larutan etanol 8 %.
Abstrct: Seeds given treatment of etanol solution with increasingly high concentration deteriorate and reduce its viability. This phenomenon is similar to seeds that were conventionaly stored for long period. The aim of this experiment is to compare seeds viability of two soybean varieties due to accelerated aging caused and natural storage period treatments. The accelerated aging uses 8% ethanol as solution with aging intensity of 0, 2, ..., 12 hours. The conventional storage storaging period last for 0 to 6 months with tempereture of 27,3±0,9 ?C. Two varieties of soybean seed that were used are Grobogan and Argomulyo. The viability measured were percentage of normal seedlings (PNS) and germination speed (GS), both were observed at the end of treatments of aging or at the end of treatments storage periods. The results showed that the seeds viability of the two soybean varieties, both measured with PNS and GS, during storage was not difterent significantly according 5% t-student test from those seeds exposured to accelerated aging treatments of  0-12 hours with ethanol solution 8%.

Dissipation studies at single and double doses of chlorantraniliprole, thiamethoxam (25 and
50 g ai ha-1), and imidacloprid (20 and 40 g ai ha-1) were conducted on okra fruits following field application, and the residues were estimated using LC-MS/MS. The initial deposit of 0.42 and 0.80 mg kg-1 of chlorantraniliprole dissipated below quantitation level on the tenth day at single and double dosages. For thiamethoxam, the initial deposits of 0.42 and 0.71 mg kg-1 reached below quantitation level on tenth day at single dosage and on fifteenth day at double dosage; and for imidacloprid, the initial deposits are 0.10 and 0.16 mg kg-1 which dissipated below quantification level on fifth day. Growth dilution plays a significant role in the rate of dissipation of thiamethoxam when compared with imidacloprid and chlorantraniliprole when simulated dissipation rate due to growth dilution was calculated. The half-life of chlorantraniliprole, thiamethoxam and imidacloprid were 1.94 and 1.72 days, 1.88 and 1.99 days, 1.13 and 1.05 days, respectively for single and double dosages.

Evaluación de la aplicabilidad de productos atóxicos y ecosostenibles en pintura contemporánea
Authors: Ferrazza Livio , Juanes Barber David
Published: October 2023

En la restauración de pintura, la limpieza se considera la operación más crítica, principalmente debido a su irreversibilidad, la dificultad de definir el nivel de la intervención y la posibilidad de aportar alteraciones o incluso daños a la obra. Tradicionalmente, se han empleado disolventes orgánicos volátiles que presentan un cierto grado de peligrosidad para la salud humana como para el medio ambiente. Ante esta situación ha surgido la necesidad de sustituir estos productos por otros más sostenibles que no comprometan la eficacia del tratamiento de restauración. A partir de principios del siglo XXI, se empezó el uso de métodos acuosos, sistemas gelificados y disolventes orgánicos ecosostenibles disponibles en el mercado como alternativa a los sistemas de limpieza tradicionales. Ante este escenario, se está llevando a cabo un proyecto de investigación cuyo principal objetivo es el estudio de la aplicabilidad de diferentes sistemas de limpieza de menor toxicidad y ecosostenibles en la limpieza de superficies pictóricas modernas del siglo XX, en las que, por el tipo de técnica pictórica o pigmentos utilizados, es probable que se encuentre con una película pictórica extremadamente delicada. La valoración de la aplicabilidad de los sistemas de limpieza ensayados, su efectividad y la permanencia de residuos se ha realizado a través de la aplicación de un protocolo de trabajo normalizado mediante una metodología científica que incluye de diferentes técnicas instrumentales de tipos microscópico (ME, MO vis-UV, SEM) y espectroscópico (EDX, FTIR-ATR).

En 2016, la portada de los Apóstoles de la Iglesia Arciprestal de Santa María La Mayor de Morella (Castellón) fue sometida a un proceso de restauración que incluyó un importante estudio interdisciplinar previo que incluyó la caracterización de los materiales presentes en la portada y la evaluación de la aplicabilidad, eficacia y riesgo de distintas metodologías y productos para las intervenciones de consolidación y limpieza de las superficies pétreas y policromas. Estos trabajos de evaluación de los procesos de intervención se realizaron en un contexto en el que la sostenibilidad no era un factor determinante e incluyeron materiales y metodologías con un importante peso los materiales sintéticos, agentes quelantes o disolventes poco sostenibles. Sin embargo, los resultados de los estudios previos demostraron que las mejoras metodologías de restauración eran aquellas que poseían un grado aceptable de sostenibilidad, convirtiendo la intervención de la portada en una restauración altamente sostenible, sin en principio, llegar a pretenderlo.
Sostenibilidad y patrimonio histórico: De la innovación tecnológica a la tradición en conservación y restauración
Authors: Vendrell Saz Màrius , Juanes Barber David , Gómez Morón Auxiliadora
Published: October 2023

En este artículo se hace una síntesis del concepto general de sostenibilidad y su aplicación al patrimonio cultural aplicando criterios que no pueden limitarse al uso de materiales ecológicos, verdes, con menos residuos y huella de carbono reducida, sino que hay que situar el bien cultural como centro de interés y considerar que cada intervención implica cierto nivel de agresión. Por tanto, se plantea la minimización y el espaciado temporal de las restauraciones y que éstas sean producto de un proceso previo de estudio, análisis, diagnóstico y finalmente, solo si es preciso, intervención. Todo esto valorando no solo la forma y la estética del objeto, sino también su materialidad y la conservación de las técnicas de ejecución históricas. Es en este punto en el que adquiere importancia el análisis mediante técnicas no invasivas que minimicen el número de muestras a extraer sin menoscabo de alcanzar la información necesaria.

En el marco de esta aproximación sostenible al patrimonio debería entenderse como una oportunidad única de tener el objeto sobre la mesa o estar a 40 cm de una estructura arquitectónica, que brindan una excelente ocasión de profundizar en su conocimiento y éste propiciará una intervención razonable y razonada. Y en el curso de la actuación y posteriormente a ésta, el estudio del objeto permitirá el diseño de un programa de control y mantenimiento que ralentice su degradación y distancie en el tiempo la siguiente intervención. Complementariamente, no cabe duda que la difusión a diversos niveles y la puesta en valor del objeto, ha de contribuir a una mejor apreciación y valoración del mismo, a todos los niveles, incluso de las propias administraciones.

Authors: Castillo Butters Luis Jaime , Barrera Yaranga Héctor
Published: October 2023

La reciente incorporación en el quehacer arqueológico de nuevas tecnologías como el uso de drones para la documentación de artefactos, contextos, sitio y regiones, y el modelamiento fotogramétrico tridimensional, ente muchas otras, están transformando la forma como los y las arqueólogas trabajan. La capacidad de volar y fotografiar desde el aire de sitos y yacimientos, y de poder capturarlos a través de complejos modelos tridimensionales que permiten su manipulación virtual, es algo que la arqueología nunca soñó y que está en marcha gracias a la adecuación simultanea de drones y fotogrametría. Este artículo se centra en una de las modalidades de documentación, la que aplicamos en las regiones arqueológicas que inspeccionamos mediate técnicas tradicionales de prospección arqueológica. Las nuevas técnicas permiten hacer el trabajo mucho más rápido, a un costo muy reducido, y con menor riesgo para el personal y sin tener que interferir con los sitios. Los resultados hablan por si mismos y abren nuevas avenidas de trabajo arqueológico profesional, de desarrollo de sistemas de protección y salvaguarda y de investigación arqueológica.

El uso de técnicas analíticas y de imagen no invasivas/destructivas ha experimentado un crecimiento extraordinario en las últimas décadas en el ámbito del patrimonio cultural. En la actualidad, su uso en el estudio de los objetos de interés patrimonial podemos decir que se ha vuelto imprescindible. Desde los años 90 se ha realizado un importante esfuerzo por parte del grupo de investigación en Ciencia de Patrimonio Cultural del Centro Nacional de Aceleradores, CNA (Sevilla, España) para desarrollar diferentes técnicas analíticas y de imagen no destructivas para el estudio de objetos artísticos y arqueológicos. Estos esfuerzos se centraron inicialmente en el uso de técnicas de análisis con haces de iones (IBA) y últimamente en el desarrollo de equipos portátiles de Fluorescencia de Rayos X (XRF), incluyendo versiones de microhaz con la implementación de lentes policapilares ( mXRF, confocal XRF) y de mapeo (MA-XRF), y de distintas técnicas radiográficas usando no sólo rayos X sino también radiaciones más penetrantes (rayos gamma y neutrones). Recientemente se han comenzado a incorporar otras técnicas que complementen las actualmente disponibles, como el empleo de cámaras hiperespectrales y de TeraHercios, LIBS, Raman y FTIR portátiles. En este trabajo se presentan los diferentes métodos e instrumentación desarrollados en los últimos años en el CNA y varias aplicaciones ilustrarán sus capacidades para el estudio de diferentes tipos de objetos, con especial atención a las obras de gran formato.
HERICARE: un proyecto de investigación eficiente y sostenible para la conservación del patrimonio cultural
Authors: García Heras Manuel
Published: October 2023

El proyecto HERICARE se ha llevado a cabo a lo largo de los últimos 3 años a partir de tres planteamientos básicos: desarrollo de estrategias eficientes de conservación preventiva de bienes culturales, conexión de la investigación científico-técnica con los usuarios finales y movilización de conocimiento de diferentes disciplinas para obtener soluciones novedosas a los retos que plantea la conservación del patrimonio cultural. Una de las estrategias de conservación preventiva implementadas en este proyecto ha consistido en el uso de sensores químicos de respuesta óptica para medir el pH ambiental mediante dispositivos portátiles en salas, almacenes, vitrinas y otros espacios expositivos de cuatro museos españoles. La importancia de medir el pH ambiental radica en que la degradación de la mayoría de los materiales de los bienes culturales se relaciona con desviaciones de la neutralidad del pH del medio circundante, de modo que cuanto antes se detecten estas desviaciones antes se podrán tomar medidas de conservación preventiva. Los sensores son reversibles, reutilizables, químicamente resistentes, tienen bajo coste y son fáciles de utilizar, por lo que pueden considerarse una tecnología verde, sostenible y no invasiva aplicada a la conservación del patrimonio cultural.

The Correlational Study of the Vertical Jump Test and Wingate Cycle Test as a Method to Assess Anaerobic Power in Road Cyclists
Authors: ULUSOY Yusuf , KOÇAK Fatih
Published: October 2023

Road Cycling is an important sport that uses anaerobic and aerobic metabolism and especially sprinter cyclists have higher anaerobic capacity. The assessment of anaerobic power in cyclists often involves the use of the vertical jump and Wingate cycle tests. The lack of research in the field of cycling-specific tests to assess anaerobic performance has led to the improvement of existing research. The objective of this research was to investigate the correlation between the vertical jump test and the Wingate anaerobic cycling tests, both of which are often used to assess anaerobic power in road cyclists. A correlation study was conducted on 15 athletes of the Turkish national road cycling team in the 14-16 age group (15.107 ± 0.717 (SD)). The sample of the study was determined by using the convenient sampling method. On the first day, anthropometric measurements and the vertical jump test were conducted. The Wingate cycle ergometer test, lasting for a duration of 30 seconds, was administered to the participants on the second day. The computer application was used to determine the 30-second peak and average anaerobic power during the test. The results acquired from the study revealed a statistically significant positive relationship between the vertical jump performance and the peak power production measured during the Wingate cycle test (r=0.321, p<0.05). The findings indicate that vertical jump tests may serve as suitable field measurements of anaerobic power for road cyclists, as an alternative to the laboratory-based Wingate anaerobic test.

Body composition values of the athletes were performed with the Inbody-720 bioelectrical impedance analyzer in accordance with the test protocols.Pre-post test measurements of body weight, total body water, body fat weight, protein, mineral, body fat ratio, BMI, skeletal muscle weight, visceral fat level, waist-hip ratio and in-body score of the athletes participating in our research were performed.In our study, there was no statistically significant difference in body fat weight, total body water, body fat ratio, protein, mineral, skeletal muscle weight, visceral fat level, BMI, in body score (p>0.05), but waist hip ratio. and body weight values were found to be significantly different (p<0.01). As a result of our study, it was determined that circuit strength training applied to wrestlers between the ages of 11-13 had positive effects on some body parameters measured by Bioelectrical Impedance technology and statistically significant changes occurred.

The learning process carried out at each individual's home experienced many obstacles during its implementation, including students easily bored, students' interest in learning decreased, and the learning process carried out was less focused so that the learning process was less effective. The learning process individually experiences obstacles because parents pay less attention to their children's learning process for reasons of being busy working, besides that it is also caused by a lack of knowledge. One solution to overcome this problem is through learning assistance activities which are part of the form of community service. Learning assistance through tutoring activities can improve achievement as well as learning motivation. The implementation of learning assistance with the group work method consists of five stages including: preparation, assessment, planning, intervention, and termination. The existence of this learning assistance activity helps students' ways of thinking become more open so that apart from influencing academics, they also learn how to socialize. This is evidenced by changes in attitude before the activity is carried out and after the activity is carried out.

The Humboldt Upwelling System (HUS) supports high levels of primary production and has the largest single-stock fishery worldwide. The high fish production is suggested to be related to high trophic transfer efficiency in the HUS. Mucous-mesh grazers (pelagic tunicates and gastropods) are mostly of low nutritious value and might reduce trophic transfer efficiency when they are locally abundant. Unfortunately, little is known about the spatial dynamics of mucous-mesh grazers from Peruvian waters, limiting our understanding of their potential ecological role(s). We provide a spatial assessment of mucous-mesh grazer abundance from the Peruvian shelf in austral summer 2018/2019 along 6 cross-shelf transects spanning from 8.5 to 16°S latitude. The community was dominated by appendicularians and doliolids. Salps occurred in high abundance but infrequently, and pelagic gastropods were mostly restricted to the north. At low latitudes, the abundance of mucous-mesh grazers was higher than some key species of crustacean mesozooplankton. Transects in this region had stronger Ekman transport, higher temperature, lower surface turbidity and a broader oxygenated upper water layer compared to higher-latitude transects. Small-scale lateral intrusions of upwelled water were potentially associated with high abundances of doliolids at specific stations. The high abundance and estimated ingestion rates of mucous-mesh grazers in the northern HUS suggest that a large flux of carbon from lower trophic levels is shunted to tunicates in recently upwelled water masses. The data provide important information on the ecology of mucous-mesh grazers and stress the relevance to increase research effort on investigating their functioning in upwelling systems.
The Intensive-Image and the Poetic Film Tradition: Notes on Ruiz, Deren, Pasolini, Buñuel and Deleuze
Authors: Escobar Cristóbal
Published: October 2023

This article analyses an important category from Deleuze's philosophy – the notion of intensity – and explores its significance for Deleuze and the ways it can be used to think about poetic cinema. I use the concept of the intensive-image to define a cinematic style that dissipates narrative action in favour of more contemplative and sensory experiences, hence films that are able to turn onscreen reality into purely affective phenomena. The notion of intensity, I argue, does not allow us to reply easily to the question about representation (i.e., “what is the film about?”), mainly because its images are indeterminate and flowing, combined in a multiple manner that excludes any simple reduction to signification. The general argument that follows, illustrated by a careful reading of key poetic texts, is that the focus on the intensive-image inspires readers to reconsider Deleuze's classification of the cinema into two separate periods as well as to understand the ways in which intensity finds expression in films that produce problems, displacements and provocations. In the words of Pasolini, this is the poetic film tradition which must be placed diachronically in relation to the language of the film narrative, a diachronism that, he says, would appear destined to be always more pronounced. In the last section of this article, I look at Luis Buñuel's Un Chien Andalou (1929) as an early case of the poetic image and draw on key theorists and filmmakers who have discussed the cinema's power of affection and intensity.
(Re)sounding Audre Lorde: Queer Crip Chorus in Lana Lin’s Experimental Documentary
Authors: Kim Hyunjung
Published: October 2023

This article discusses the artist, filmmaker, and writer Lana Lin’s “revisioning” of Audre Lorde’s The Cancer Journals (1980) to consider how the poetic encounter between two artists from different generations exemplifies the relational praxis that Lorde pursued throughout her life. In revealing the ways in which Lorde opens acoustic sensory spaces for contemporary readers and listeners of her work, I specifically focus on the political and aesthetic dynamic of recitation in Lin’s experimental documentary The Cancer Journals Revisited (2018). I trace how recitation becomes a coalitional practice of feminist chorus through which readers and listeners embody the sonorous space they co-create through and with Lorde. The article further looks into the ways Lin pairs recitation performance with visceral images of body parts on the screen to argue that the film’s visuals dwell in and extend the form of the chorus; which is to say, the film expands the meaning and practice of chorus beyond the realm of the sonic. The bodies on the screen extend the chorus, immersing the audience in a participatory rethinking of the experience of cancer (particularly breast cancer) not merely as an individual misfortune or an aesthetic concern. In adjoining textual, visual, and acoustic elements, Lin’s film provides a powerful transformative sensory environment, reverberating through the reciters and the audience.
Lost and Beautiful or the (Environmental) Ethics of the Lyric Essay Film
Authors: Rascaroli Laura , Saporito Paolo
Published: October 2023

This article contributes to a theory of the lyric essay film by bringing studies of the essay film and lyricism to bear on Pietro Marcello’s Lost and Beautiful (2015). We argue that the lyric essay film delivers its argument by leveraging the tension between words and images, narrative and counter-narrative components, and the (non)human subjectivities (i.e. the director’s, characters’ and camera’s) its text embodies and enacts. These tensions generate interstitial sites from which the ethics and politics of the lyric essay film emerge. Insofar as the lyric essay film is marked by the intrusion of subjectivity in the genre’s argumentative structure, the polyvocality that this intrusion allows in terms of both critical and affective contribution to the film’s argument is what enables the lyric essay film to undermine ideological homogenisation and the naturalisation of situated subjective positions. Moreover, the felt participation of the subjectivity of the camera in the rendering of reciprocal processes of subjectivation becomes ethically meaningful as it embodies a conception of subjectivity as co-determined by otherness. The ethical significance of this interaction is also relevant to contemporary environmental thought, as it maintains that human subjectivities are co-determined by human and nonhuman others.
Humanities Pedagogy in a Pandemic Context: Maintaining High-impact Practices in Virtual Classrooms

Published: October 2023

The arrival of the COVID-19 pandemic and its disruption of post-secondary education turned future planning for online courses into an immediate reality. Given the in-person limitations, courses centred on experiential learning (EL) opportunities were challenging to offer without their curricula undergoing extensive reconsideration. This article highlights how two Italian Studies courses at the University of Toronto (U of T) and University of Toronto Mississauga (UTM), known for their in-person EL opportunities and study abroad, were able to provide highly interactive, global learning spaces online through the deployment of digital technologies and inclusion of redesigned high-impact practices (HIPs). What emerged from these new virtual spaces and adjacent components (e.g. virtual lectures, tours, workshops, assessments) were models for the preservation of academic integrity, frequent peer-to-peer interaction, and innovative ways to put learners into direct contact with Italian culture. Drawing from these successes and from current scholarship in teaching and learning, the courses at the centre of this article – Modern Italian Culture (ITA358/9Y0, U of T) and Italian Culture through Food (ITA235H5, UTM) – are presented as case studies which champion the inclusion of digital learning tools, open access and virtual opportunities across humanities curricula, regardless of delivery mode.
Zooming In
Authors: Reichgelt Marleen
Published: October 2023

At the heart of this article is the presence of Indigenous children in photographs of explorative travels taken by Dutch Missionaries of the Sacred Heart of Jesus in Netherlands New Guinea (present-day West Papua, Indonesia) in the early twentieth century. Departing from the hypothesis that the children may have been guiding the missionaries, this research studies if and how young West Papuans acted as ‘local intermediaries’ in the early years of colonial settlement. ‘Zooming in’ on engagements between missionaries and children in both visual and textual sources, two paradoxical aspects of Indigenous children in missionary archives are grappled with: their centrality as objects of civilising practices on the one hand, and their marginalisation as historical subjects in colonial textual practices on the other. The visual and textual are brought in conversation: the active presence of children as individual historical actors participating in processes of colonisation in the photographs helps to see children and their actions in ‘still’ discourse, to contextualise captured instances in time and space. This shows how and when missionaries depended on the knowledge, skills, and networks of local children to introduce them to their new working ground. This article thus adds to the existing body of literature on colonial intermediaries, in which young people constitute an overlooked group, and to complement understandings of non-elite colonial childhoods of Indigenous children outside of familial or institutional contexts.
