En este artículo expondré cómo, desde los espacios liminares del exilio y la frontera, María Zambrano y Gloria Anzaldúa realizan una crítica a diversos aspectos de la Modernidad epocal, a la vez que recuperan otras formas de conocimiento, saberes y tradiciones rechazadas por la racionalidad moderna, insertándose, de este modo, en un camino ancestral que configurará su propia modernidad.

While Bubonium graveolens (Forssk) Maire, locally known as "tafss," is renowned in traditional medicine for its diverse therapeutic properties, a comprehensive analysis linking its phytochemical profile to mechanistic bioactivity is lacking. In this study, the in vitro antimicrobial, anti-inflammatory, and antioxidant activities of its essential oil (EO) were evaluated using the disc diffusion, broth microdilution methods, and solid double dilution, the bovine serum albumin denaturation assay, and the 1,1-diphenyl-2-picrylhydrazyl radical scavenging test. The characterization of its phytochemical composition by gas chromatography coupled with mass spectrometry allowed for the identification of the main bioactive compounds: 3-methyl-3-cyclohexen-1-one (3.77%), dihydrocarvyl acetate (16.05%), cadinene (12.68%), butylated hydroxytoluene (4.24%), chrysanthenylacetate (2.57%), and β-panasinsene (2.42%). EO exhibited potent antimicrobial activity, particularly against Acinetobacter baumannii (DZI: 16mm; minimum inhibitory concentration: 500µg/mL), and reduced biofilm formation by up to 53%, whereas EO demonstrated superior antioxidant (IC50: 4.77µg/mL) and anti-inflammatory effects (maximum inhibition: 82.54% ± 3.11 at 2500µg/mL). Molecular docking analysis reveals strong interactions between the six major compounds and their biological targets. Furthermore, Absorption, Distribution, Metabolism, Excretion, and Toxicity profiling, combined with density functional theory studies, suggest that these compounds exhibit favorable pharmacokinetic and reactivity profiles, highlighting their potential as promising bioactive molecules for therapeutic applications.

This study examined the genre‑based progression of writing competence from 5th to 7th grades of Ecuador’s Basic Education across contrasting settings: Guayas (coastal, more urban) and Chimborazo/Cotopaxi (Andean, more rural/indigenous). We employed an explanatory sequential mixed‑methods design (QUAN→qual) combining: (i) primary sampling of authentic student texts in four school genres (narrative, news report, description, procedural/instruction), scored with analytic rubrics (α/κ ≥ 0.70; metric invariance across provinces); (ii) extraction of NLP metrics (lexical density, T‑unit length, referential cohesion, connectives); and (iii) linkage with open data (SEST‑INEVAL grade‑7 scores; AMIE; H3/OSM/WorldPop/VIIRS). Analyses included multilevel models (student–section–school), Genre Progression Index (GPI) estimates, and school‑level correlations with SEST. Findings indicate a substantive 5th→7th progression that varies by genre, with steeper gradients in news and procedural writing. Guayas shows a relative advantage in news (higher GPI and grade slope), tied to improvements in inverted‑pyramid structure, lead quality, and source use; the Andean sample displays qualitative strengths in register and audience alignment. NLP metrics partially mediate the grade effect (indirect β ≈ 0.06), adding sensitivity to textual complexity. At the school level, news writing (grade‑7) is the strongest predictor of SEST Language & Literature (β ≈ 0.31), followed by procedural writing (β ≈ 0.24). Robustness held under design weights, multiple imputation, and alternative specifications. We conclude that genre‑based instruction—making macrostructure and cohesion explicit through mentor texts and formative feedback—accelerates writing development. We recommend hybrid sequences (deconstruction→joint writing→independent writing), emphasis on news/procedural genres, and low‑cost kits (templates and open rubrics) prioritizing rural and EIB contexts. The open‑data package (anonymized microdata, scripts, JSON‑LD metadata) enables replication, auditing, and responsible scaling

Al-Maghrah region, 280 000 feddan, like the most locations of million and half feddan project is mainly depended on the well water of various degrees of salinity stress (4000 – 8000 ppm) that may be prevents cultivated crops from realizing their full yield. Barley is considered to be one of the best crops that can withstand difficult environmental conditions, such as salinity, as in the Al-Maghrah region. A germination experiment was conducted at Laboratory of Seed Technology Research Department, Field Crops Research Institute, Agriculture Research Centre to study the impact of seed treatments (dry seeds, hydro-seeds, and magneto-primed seeds) on germination characteristics, seedling development, and vigour of barley. Results cleared that that magnetized barley grains treatment (soaking barley grains in magnetized water for 8 hours before sowing) surpassed dry grains or hydro-grains treatment (soaking barley grains in tap water for 8 hours before sowing) in germination traits at 14 days after sowing. The improvement ranged between 5.00 – 40.68% compared to dry grains treatment and 3.52 – 24.82% compared to hydro-grains treatment in tested germination parameters. Positive effects were observed in MGT, where it is faster by 19.84% compared dry grains treatment and 11.54% compared to hydro-grains treatment. Under field conditions. Four field experiments were conducted during winter seasons (2022-2024) to alleviate salinity irrigation water stress using the application of magnetic technology combined with foliar spraying of humic acid at 45 and 60 days after sowing on the productivity of barley crops.

This work focused on enhancing the efficiency of thermal behaviour in the application of Cold Metal Transfer (CMT), especially for welding tough metals like titanium, which has the potential to impact the field of welding technology significantly. The investigation of the thermal behavior of CMT welding, carried out by means of parametric analysis, was a crucial step in this direction. This study, which was carried out with the assistance of numerical simulations with COMSOL Multiphysics, particularly emphasized critical factors such as plate thickness and welding power. The significance of this study in advancing our understanding of additive manufacturing in welding is highlighted by the results of the study. These results, which illustrate the effects of the specified influencing parameters through temperature distribution at various time intervals, 2D and 3D graphs depicting temperature evolution along the welding path, and the 2D temperature profile at (t=5s) across different plate thicknesses, have the potential to revolutionize the field of welding technology and bring about exciting new possibilities.  

Recently, multiple teams reported the successful utilization of denuded oocytes matured in vitro after controlled ovarian stimulation, as well as their small but significant contribution to cumulative live-birth rates after intracytoplasmic sperm injection (ICSI). Published data are in favor of rescue ICSI when mature oocytes are obtained one day after oocyte pickup, the clinical contribution being higher for patient with advanced maternal age, low ovarian response to COS, low maturation rate, or low fertilization rate. From a strictly resource-oriented perspective, rescue ICSI of immature oocytes may not be cost-effective as it would require additional expenses related to consumables, media, and embryologist time and as the developmental potential of such oocytes is consistently decreased across reported studies compared to their sibling mature oocytes. Being able to select the right clinical context as well as the right oocytes to fertilize to optimize outcome and resources spent is thus of significant clinical value. In that regard, even if more costly than conventional culture, time-lapse imaging may play an important role as morphokinetic markers of oocyte maturation and oocyte developmental potential have been described. However, the limited number of reported cases warrants for the restricted use of rescue ICSI only in registered clinical trials with long-term follow-up of children obtained from this still experimental procedure.
