The author highlights the work's visionary nature, placing it even beyond the aesthetic standards of experimental cinema of its time, both Argentine and international. Honik, who worked as a physician, links his life experience to the creation of the film: the images he recorded emerged so forcefully from his surroundings that he could not separate his hand from the camera. This union is interpreted in McLuhan's terms as a prosthesis of the gaze, but what emerges from it is not merely a technical extension, but rather images that become organs of perception, possessing an unheard-of nakedness and an almost sacred harmony. A parallel is drawn with representatives of Absolute Cinema (such as Ruttmann, Eggeling, and Fischinger), as Honik constructs a symphonic visual rhythm in a silent film. Following Michel Chion's question about what we hear from what we see, the text suggests that the images—torn from the flow of life—evoke sounds and music through their rhythmic and precise succession. Finally, the text underscores the uniqueness of Honik's gaze, comparing it to that of a Tuareg: its beauty lies not in an art conscious of itself, but in the ability to bear witness to a nature that finds, almost by chance, a gaze worthy of it.

Although this represents less than 1% participation at the national level, it is a region where the cultivated area is continuously increasing and constitutes a strategic option as an input for meat production in Argentine Patagonia. The average yield is around 11,000 kg/ha. As with all crops in this region, maize production requires irrigation to achieve yields (production is null without irrigation). Considering the growing decrease in water availability for irrigation in the region, it is necessary to implement actions aimed at improving the efficiency of water resource use, focusing on maximizing water productivity. In this regard, standardizing the calculation of maize crop irrigation requirements will help increase the efficiency in the use of productive inputs such as water and fertilizers.In this study, the FAO 56 methodology is applied with the support of satellite information in order to validate its use in maize cultivation.

Clinical simulation provides conditions to foster comprehensive teaching and learning processes, although it is necessary to understand student acceptance as a way to evaluate and improve the strategy. The objective of this study was to analyze the perception of medical students after introducing clinical simulation sessions to optimize the teaching and learning processes of communication skills. The study design is observational, cross-sectional, mixed, and uses census sampling. A survey was conducted through a questionnaire, and a descriptive analysis of the results was performed. The results reveal a generally good perception, where the majority of students highlighted the debriefingspace or final reflection (64.8%), while 27.8% valued clinical simulation as a space for applying knowledge and more than 20% referred to the simulation scenario or the experience with a simulated patient. In conclusion, the most notable space was debriefing as an area for reflection and learning, although other appreciated aspects such as the application of knowledge or the use of a simulated patient are also important in understanding clinical simulation as a tool for learning communication skills Mon, 01 Apr 2024 00:00:00 GMT http://rid.unrn.edu.ar:8080/handle/20.500.12049/14187 2024-04-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/14186 Título: Evaluación de la etapa virtual del curso de ingreso a la carrera de Medicina de la Universidad Nacional de Río Negro, Argentina Autor(es): Bellotti, Mariela Inés; Tognetti, Celia Abstract: Introduction. The entry course for Medical School at the Universidad Nacional de Río Negro-Sede Andina, Argentina, consists of three mandatory and selective phases. The implementation of the first of these phases, which is carried out online, was evaluated in this work. Subjects and methods. A cross-sectional descriptive study was conducted. Students’ perception of the virtual classroom was assessed through an online survey which covered aspects such as classroom content, teaching performance, synchronous virtual meetings and interaction between participants. Results. Most (95%) of the surveyed population was satisfied with the online phase of the entry course. The materials offered in the virtual classroom were considered adequate, as was the performance of the teaching team. Synchronous virtual meetings were considered useful, while the interaction between the students themselves was not considered as effective at this stage. Conclusions. Students had a positive perception regarding the online phase of admission, and areas for improvement were identified. This work provides evidence on the usefulness of virtual classrooms as support for the learning of university students.

The objective of this study was to analyze the different communication channels through which prospective students became aware of the UNRNAndean Campus Medical Program, as well as the motivations behind their decision to choose it. This is a quantitative, correlational study based on an online survey administered to applicants who had completed the virtual stage of the admission course. The survey explored how candidates learned about the program and the reasons for their choice. The results indicate that outreach efforts have a direct or indirect impact on future students, with family and friends’ recommendations, traditional media, and social media standing out as particularly influential. Regarding motivations for choosing the program, geographic location and institutional identity emerged as key factors in the decisionmaking process. The findings support the idea that a structured and cohesive promotion strategy can enhance student recruitment, and they also validate the relevance of geographic factors—one of the foundational arguments for establishing the program in the Andean region Mon, 01 Sep 2025 00:00:00 GMT http://rid.unrn.edu.ar:8080/handle/20.500.12049/14180 2025-09-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/14179 Título: Gestión del conocimiento en universidades: estudio de caso en Bariloche, Argentina Autor(es): Dávalos González, Diego Fernando; Bellotti, Mariela Ines Abstract: This study focuses on knowledge management in public high-er education institutions located in San Carlos de Bariloche, Argentina, from both theoretical and empirical perspectives. A mixed-method approach was applied, combining documen-tary analysis and a validated questionnaire administered to academic authorities at three institutions. The results show an intermediate level of maturity in knowledge management, with strengths in application and use, and weaknesses in knowledge creation and storage. Notable practices include fac-ulty training and professional autonomy, although deficien-cies persist in information systematization and institutional coordination. The study concludes that the analyzed institu-tions have significant potential to strengthen more effective knowledge management systems, which requires institutional policies, technological investment, and the development of a collaborative organizational culture Mon, 01 Dec 2025 00:00:00 GMT http://rid.unrn.edu.ar:8080/handle/20.500.12049/14179 2025-12-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/14178 Título: Experiencia de curricularización de la extensión en la carrera de medicina de la Universidad Nacional de Río Negro Autor(es): Guaresti, Germán; Perner, Serena; Bellotti, Mariela Ines Abstract: University outreach, as a core function of higher education alongside teaching and research, has gained increas-ing relevance in recent years. In particular, its formal integration into the curricula of Health Sciences programs—known as extension curricularization—poses a strategic and pedagogical challenge with high transformative po-tential. This study analyzes the implementation of this strategy in the recently created Medicine program at the Andean Campus of the National University of Río Negro, in San Carlos de Bariloche, Argentina, using a mixed-meth-ods design. Institutional documents were examined and surveys were administered to students to assess their perception of the contribution of the Fieldwork course to the learning process. The results show a positive eval-uation, with an average agreement level of 78.4%, reinforcing the effectiveness of the territorial approach as a training tool. However, variations between cohorts and curricular units were observed, indicating the need for a situated pedagogical review. It is concluded that the curricularization of extension supports the comprehensive education of future health professionals by articulating academic knowledge with the social issues of the territory Wed, 01 Oct 2025 00:00:00 GMT http://rid.unrn.edu.ar:8080/handle/20.500.12049/14178 2025-10-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/14176 Título: Successional stages of a Maastrichtian plesiosaur fall community from Antarctica Autor(es): Talevi, Marianella; Brezina, Soledad Silvana; Lazo, Darío G. Abstract: Research on ecological successions in recent skeletal remains, such as those of whales, has revealed specific colonization patterns and four distinct succession phases. These succession patterns can also be inferred in the fossil record from evidence such as bioerosion traces, bone encrustation, and associated body fossils. The study of ecological successions in fossil bones of Mesozoic marine reptiles not only helps to understand the phases of degradation and entombing in the past but also contributes to our knowledge of the communities associated with these carcasses during that time. In this work, the presence of sclerobionts (represented by micro and macroborings) in bone remains of a plesiosaur from the upper Maastrichtian of Antarctica was identified and described, interpreting the phases of ecological succession in a high-latitude marine environment. Macroborings were assigned to Trypanites and Osedacoides. The microborings, similar to Wedl tunnels, were attributed to cyanobacteria and fungi, indicating that the bones were exposed for a long time. Furthermore, framboid pyrite in the bones shows anaerobic stages associated with bacterial activity. The four known stages of ecological succession were documented: the mobile scavenger stage, identified by bite marks; the opportunistic enrichment stage by Osedacoides; the sulfophilic stage, marked by modified vascular channels filled with pyrite; and the reef stage, by Trypanites traces, which indicate colonization by organisms before final burial. These findings enhance our understanding of the interactions between microorganisms and mineralization in ancient marine vertebrates, and aid in reconstructing paleocommunities associated with marine reptile falls, offering valuable insights into past ecosystem dynamics.

Macrofauna (>2 mm) was extracted using soil monoliths from plots with three treatments and replicates per year. Organisms were classified as ecosystem engineers, detritivores, herbivores, and predators. Additionally, soil variables such as moisture, bulk density, pH, electrical conductivity, and organic matter fractions were measured. A total of 869 individuals were collected, distributed across24 families and 10 orders. Ecosystem engineers were the most abundant group, followed by detritivore-herbivores and predators. The no-tillage treatment showed greater total abundance compared to other treatments. However, when considering interactions among functional groups, management, and year, engineers and predators exhibited lower abundance under no-tillage, though engineers significantly increased their abundance in this treatment between 2018 and 2020. Earthworms (Crassiclitellata) and isopods (Isopoda) were the most representative taxa. Soil pH negatively affected engineers, while electrical conductivity was positively associated with detritivores. After three consecutive cycles under these management practices, macrofauna abundance was not favored, and burned residue proved particularly detrimental. The proportions of functional groups and their temporal variation reflect the degree of soil disturbance and the availability and quality of trophic resources. In this context, no-till appears to be themanagement option with the least impact on soil macrofauna abundance Fri, 08 Aug 2025 00:00:00 GMT http://rid.unrn.edu.ar:8080/handle/20.500.12049/14160 2025-08-08T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/14159 Título: Digitalización y sistematización de la información edáfica histórica del Valle Inferior del Río Negro, Argentina Autor(es): Sylvester, Ana Paula; Neffen, Evelyn María; Bazzani, Julia Lucia Abstract: In the Lower Río Negro Valley (VIRN), during the 1960s, soil surveys were carried out that made it possible to characterize and group soils according to similarities in their components (texture, drainage, parent material, geomorphology, among others), taking into account the different profile horizons. These surveys resulted in the delineation of 15 soil mapping units of the soil-association type, represented inprinted maps at a scale of 1:75,000, which are locally referred to as “soil series”. This information provided the technical basis for irrigation planning by the Lower Valley Development Institute (IDEVI). However, current access to these materials is limited due to their physical format and the partial loss of some original documents. In this context, the aim of this work was to digitize, georeference, and integrate the historical soil maps from IDEVI and their extension towards the coastal area into a unified Geographic Information System (GIS), covering a total area of 42,071 ha, using the open-source software QGIS. The main outputs include raster and vector products; unified soil maps, zoning based on soil attributes within the GIS environment, the recovery of previously lost information, and the reworking of the historical cartography for its visualization al scales of 1:120,000 (irrigated valley) and 1:200,000 (integrated valley-coast area), with cartographic layouts of adecuate readability and scalability. These products not only preserve a valuable technical legacy, but also provide updated tools to support research, outreach, and sustainable land management decisions in the region.

In this framework, the nuclear industry is inserted in this process by promoting the development of new reactor concepts aimed at complementing themselves with renewable generation sources. This work analyzes the development of the Argentine nuclear industry, taking as a starting point the decision adopted in 2006 to relaunching a nuclear development plan. In particular, it is interesting to identify what technological choices were made and provide evidence to analyze what challenges they face and what role the relatively less developed countries will play in said process.

However, the predominance of the Andreia cultivar has reduced genetic diversity, increasing its vulnerability to environmental fluctuations and limiting the selection of new genotypes with desirable malting traits. Based on the hypothesis that significant biochemical variability exists among the commercial genotypes currently available in Argentina, this study provides the first comprehensive assessment integrating germination performance, protein content, hordein composition, and amylolytic enzyme activity in these genotypes. Twelve malting barley genotypes were evaluated under uniform growing conditions, and biochemical analyses were conducted on micromalted grains. Gel Electrophoresis revealed polymorphisms mainly in B- and C-hordeins, supporting genetic differentiation among cultivars. The total protein content ranged from 9.5% to 13.2%, whereas soluble hordeins varied from 5.8% to 12.9% of the total protein. α-Amylase activity values ≥ 150 U/g were observed in all cultivars evaluated, except for Sinfonía. However, amylolytic activity, which is related to diastatic power, was higher in genotypes such as Andreia, Alhue, Aliciana, and Jennifer. Correlations between protein content, enzyme activity, and hordein profiles indicated genotype-dependent biochemical patterns in the barley grains. Overall, this study highlights the existence of relevant biochemical diversity among Argentine commercial genotypes, providing valuable information for breeding programs aimed at improving malting quality and promoting productive diversification in the national barley industry.
