Authors: Cui Kaibo , Zhang Tianzhu , Rao Tao , Zhang Xianghui , Zhang Shunping , Xu Hongxing 
Published: July 2024

Abstract
High-order wave mixing in solid-state platforms gather increasing importance due to the development of advanced lasers and integrated photonic circuit for both classical and quantum information. However, the high-order wave mixing is generally inefficient in solids under weak pump. Here, we observed the presence of phase matching of five-wave mixing (5WM) propagating in a zinc oxide (ZnO) microwire. The 5WM signal is enhanced by 2–3 orders of magnitude under the phase matching conditions, reaching an absolute conversion efficiency of 1.7 × 10−13 when the peak pumping power density is about 106 W/cm2. The propagation of multiple nonlinear signals, including sum frequency generation, third harmonic generation, four-wave mixing etc., benefited from both the large nonlinear coefficients and the wide transparent window of ZnO, implies the possibility of developing cascaded nonlinear process under higher pumping. This study enriches the ZnO platform for integrated nonlinear nanophotonics.

Published: July 2024

Abstract
Nanofluid flooding is a novel technology with potential for enhanced oil recovery. In this study, a biological nanocomposite system was formed by mixing hexamethyldisilazane-modified hydrophobic nano-SiO2 with a biosurfactant produced by Bacillus. The stability of the system, its influence on rock wettability, and fluid interfacial tension were investigated experimentally. Numerical simulation methods were employed to simulate the displacement efficiency of the biological nanocomposite system and optimize the injection parameters. Finally, the application effects of the system in the field were evaluated. Results indicated that the biological nanocomposite system could change rock wettability and significantly reduce the interfacial tension to 1.8 mN/m at low concentrations. The core flooding results showed that the maximum oil recovery factor of the system reached 47.07%. Numerical simulations optimized the optimal injection concentration to be 7,000 ppm and the volume of injection to be 1.75 × 10–2 pore volumes, resulting in an oil increment exceeding 10,000 m3 in field application. This study provides a solution for the green development of oil reservoirs and provides effective technical support for the numerical simulation and process scheme optimization of biological nanocomposite systems.
Ovidio, Cicerone e il finale delle Metamorfosi
Authors: Berti Emanuele 
Published: July 2024

Abstract
The finale of Ovid’s Metamorphoses contains a sphragis in which the poet proclaims the immortality of his poetic work and the eternal survival of his pars melior (Ov. Met. 15.871–879). These lines present a number of rather close parallels with excerpts from the seventh suasoria of Seneca the Elder’s collection, whose theme is Deliberat Cicero an scripta sua comburat promittente Antonio incolumitatem, si fecisset. Allusions to this declamatory exercise may activate in the Ovidian passage a reference to the theme of book-burning, evoked especially by the term ignis in line 871: this form of censorship against authors disliked by the imperial regime began to appear toward the end of Augustus’ principate, in the very same years when Ovid completed the composition of his Metamorphoses, before in turn being exiled by Augustus (an event to which the phrase Iovis ira, again in line 871, may allude). But at the same time, in the face of such a possible threat, Ovid affirms the certainty that his work will nonetheless prove stronger than fire and grant him perpetual life.
HACIA UNA CATEGORIZACIÓN DE LAS REVISTAS CULTURALES: LOS REFERENTES EN LAS CITAS
Authors: Pita González Alexandra 
Published: July 2024

Convertir una revista en un objeto de estudio autónomo requiere no solo un análisis profundo de cada caso, sino también una reflexxión de las categorías que utilizamos para estudiarlas. Subraya la importancia de distinguir los registros específicos de las revistas culturales, las cuales deben ser comprendidas por sus propias características. Sin esta dimensión teórico-metodológica no podremos superar los límites de los estudios de caso. Por ello, este texto reflexiona sobre la manera en que distintas disciplinas han estudiado las citas en las publicaciones periódicas (bibliometría, semiótica, literatura e historia). Para problemzatizar esto, diferenciamos de inicio, la cita como acción tomada por un autor para hacer referencia a un trabajo del que se saca una idea o un dato, a la del referente como sujeto que son incorporados en una revista de manera indirecta con fines de legitimación. Más adelante, hacemos una propuesta de análisis de estos referentes como parte de la red intelectual que da vida a una revista cultural. Por esto, más que hallazgos definitivos, las conclusiones apuntan sintetizar estas reflexiones y proponer a su vez nuevas preguntas para seguir pensando el dilema que implica la práctica de la cita como una vía para adentrarse en las estrategias, sentidos y vínculos de quien enuncia y de la publicación que consiente publicarlasPalabras claves: publicaciones, análisis cualitativo y cuantitativo, citación
SENTIMIENTO DE MARGINALIDAD Y PROYECTOS EDITORIALES EN LAS CULTURAS DE REGIONES
Authors: Maíz Claudio 
Published: July 2024

En este trabajo nos ocuparemos de un sentimiento de marginalidad que experimentan los productores de publicaciones culturales alejados de los centros de mayor relevancia y prestigio. De acuerdo con las teorías sociológicas de la marginalidad, quienes la vivencian se sienten víctimas de un conjunto de desventajas y por ende una emoción inquietante invade el discurso que da cuenta de ello. La experiencia de la brecha interpuesta entre un lugar y otro se hace perceptible a partir de un punto cero o “meridiano de Greenwich”, al decir de Pascale Casanova, desde donde medir la pretendida “marginalidad”. Para el momento que trataremos, en la cultura argentina ese punto lo ocupa la ciudad de Buenos Aires. En el otro margen, los creadores de la revista Tarja (1955-1960) - uno de los tantos casos que podrían analizarse-, se conciben como habitantes de la provincia argentina de Jujuy en contrapunto con aquel meridiano imaginario.

The accuracy of the construction of "depth maps" of space using an active-pulse television measurement system is evaluated on the basis of experimental data. Two multi-area methods of constructing "depth maps" are described. Results of estimation of the absolute and root-mean-square errors of range measurements for "depth maps" constructed from real and averaged frames obtained by the multi-area methods mentioned above in experimental studies are presented. The approximating functions of linear and polynomial types calculated by the least squares technique are taken as measuring functions used to construct the depth maps.
« Désenchantée », le charme pop d’un hit transgénérationnel
Authors: Marc Isabelle 
Published: July 2024

« Désenchantée » (1991) est le titre emblématique, la signature sonore de la carrière de Mylène Farmer, peut-être la star la plus méconnue de la musique pop en France. Succès commercial et véritable tube, « vers d’oreille » transgénérationnel, « Désenchantée » a fait l’objet de nombreuses reprises et connaît un engouement récent chez les artistes et les publics jeunes en France. Ce travail se propose précisément d’explorer les raisons d’ordre esthétique et culturel qui ont pu contribuer au succès commercial et populaire de « Désenchantée ». Pour ce faire, nous présenterons en premier la figure de Mylène Farmer, diva incontestable pour ses fans mais grande inconnue de la critique dite « sérieuse », marquée par l’ambivalence dans sa réception mais aussi dans son esthétique. Deuxièmement, nous explorerons les mécanismes expressifs du morceau, notamment sa facture aphoristique et paradoxale où le nihilisme référentiel contraste avec les usages festifs au fil des années dans le contexte de l’histoire culturelle française récente. Enfin, « Désenchantée » sera analysé par rapport à l’esthétique pop de Farmer, une esthétique marquée par l’accessibilité, l’imprécision, l’immédiateté, relevant d’une alchimie mystérieuse, capable de rassembler un public majoritaire autour d’un objet simplissime mais émotionnellement irrésistible.

Authors: . Kamal , Dhaka A.K. , Singh Bhagat , Kamboj Ekta , Rana Anjali , . Ravi 
Published: July 2024

Background: Groundnut, a well-recognized oilseed crop belonging to the Leguminosae family, faces several challenges in India that results in lesser productivity compared to the global average. The principal underlying cause of India’s diminished groundnut production lies in the irregular and inadequate utilization of essential nutrients. Given its status as a leguminous oilseed crop, it exhibits a heightened demand for phosphorus, calcium and sulphur, which often remains unmet, further exacerbating the problem. Methods: In a field experiment, split-plot design was employed to investigate the impact of four phosphorus levels (Control, 40, 50 and 60 kg P2O5 ha-1) and four sulphur levels (Control, 25, 50 and 75 kg S ha-1) on the growth parameters of groundnut. Results: The findings demonstrate that the utilization of phosphorus and sulphur fertilizers yielded significant improvements in various aspects of groundnut growth parameters. These improvements encompassed increased plant height, root length, improved root-to-shoot ratio on a length and weight basis, greater numbers of root nodules per plant and dry weight of root nodules per plant.

Published: July 2024

The main supporting component of a comprehensive learning implementation, scientifically prepared according to the chemical context, is developing a chemistry lesson plan. Scientific explanations in chemistry learning often involve causal mechanistic explanations of chemical phenomena, which provide a paradigm for understanding chemical concepts. This research aims to describe how prospective chemistry teachers use scientific explanations to develop CER framework in chemistry lesson plans that align with STEM learning. A descriptive qualitative research design was used. The authors conducted this research on 20 prospective chemistry teachers. This research used the document review, observation, CER framework assessment, and interviews. Prospective chemistry teachers can theoretically and practically prepare chemistry learning plans. The study reveals that prospective chemistry teachers struggle to offer scientific explanations for the concepts they explain through CER framework. Their responses to the CER framework assessment reveal numerous unconnected scientific explanations. One cannot combine evidence and reasoning claims into a systematic unity to explain a chemical phenomenon.

Climatic determinants of the Carpathian treeline and its projected upward shifts in response to climate change
Authors: Mkrtchian Alexander , Mueller Daniel 
Published: July 2024

Abstract

Treelines represent a significant ecological boundary in mountainous regions. Changes in temperature and precipitation regimes due to climate change affect the location of treelines, contingent on fine-scale variations in orographic and climatic conditions. Using high-resolution satellite imagery, we identified climatic treelines in the Carpathian Mountains, one of Europe’s largest contiguous forest ecosystems. We downscaled climate variables to a 30-meter resolution through a polynomial approximation of regression residuals with terrain attributes, then correlated climatic variables with the location of the climatic treeline. Growing degree days above 5°C demonstrated the strongest correlation with treeline location. Our growing degree threshold results in a total area of 1,370 km2 above the current climatic treeline in the Carpathians. This area constitutes the climatic envelope for alpine ecosystems and comprises the highest ridges and peaks. Using future climate projections, this area will likely decrease to 410–515 km2 by 2040, 100–320 km2 by 2060, and 15–290 km2 by 2080. The upward shift threatens the region's rare and endemic alpine species and will trigger substantial ramifications for ecosystems, water balance, and the carbon cycle in the Carpathian Mountains. A better understanding of the effects of climate change on treeline locations is crucial for informing ecosystem management and conservation planning, as well as to cushion the impacts of climate change on agriculture and forestry practices.

Published: July 2024

Abstract

Introduction:
Clinical practice is an important part of nursing education as it helps nursing students transition into competent health professionals who can provide quality services. However, research studies convey it as a significant stressor for nursing students when they are obliged to end of life during clinical practice. The perceptions of nursing students on caring for end-of-life care have not been exhaustively studied in the Ugandan context. This study was conducted to understand nursing students' perceptions of end-of-life care during clinical practice at Mulago Hospital.
Methods
It was a qualitative study with a phenomenology method carried out among 15 nursing students from Makerere University who were assigned to Mulago Hospital for clinical practice. Data was gathered using an in-depth interview guide, audio was captured, and transcriptions were analyzed thematically using Atlas.ti version 6.
Results
Three main themes emerged from the data; two themes on perceptions were (i) reactions when nursing students were informed about the physical process of caring for dying patients and (ii) how student ideas about the care changed during the process of caring for end-of-life. The third theme was the attitude of students towards patients when offering end of life care. participants described their reactions as chaotic, devastated and scared about their first-time encounter with caring for dying patients, the physical process also required preparation to handle the situation and understanding, and for positive personal values felt respected, appreciated, trusted and valued when informed about the physical process of caring for the end-of-life
Conclusion: In this study, nursing students held divisive attitudes on care for dying patients. However, nursing students appear to transition from unfavorable impressions of the process and encounter of caring for dying patients to positive perceptions during the actual caregiving experience. Despite their differing perspectives on caring for dying patients, students were typically empathic towards them.
