Authors: Moreno Jaramillo Naomy Paulette , Dueñas Jaramillo María Belén , Apolinario Rojas Alfredo Javier , Sosa Moreno Ana Julia
Published: February 2025

Las mordeduras en pacientes pediátricos son causadas en un 80-90% por perros, representando hasta el 1.5% de las consultas en emergencias. La mayoría de los casos ocurre en niños de 5 a 9 años, aunque los menores tienen mayor riesgo de muerte, ya que las lesiones suelen afectar la cara, cabeza o cuello. Comúnmente, los ataques provienen de perros de la familia o vecinos, con razas como pitbulls, chows, rottweilers, huskies y pastores alemanes implicadas en incidentes mortales. La incidencia de infecciones es del 15-20%, apareciendo entre 24 y 72 horas después del incidente, con síntomas como fiebre, eritema y abscesos. El tratamiento incluye analgésicos y antibióticos, siendo amoxicilina/clavulánico la primera línea. La sutura de heridas es discutida por el riesgo de infección, aunque el manejo temprano generalmente reduce la infección y mejora resultados estéticos. Este estudio, de tipo observacional, retrospectivo y descriptivo, analizó historias clínicas en el Hospital Roberto Gilbert Elizalde desde enero de 2020 hasta agosto de 2024. Se registraron 348 casos de mordeduras de perro, con un aumento en 2021 (99 casos). El 41.10% de los pacientes eran mujeres y 58.90% hombres; el 39.95% tenía entre 5 y 10 años. Las mordeduras más frecuentes ocurrieron en la cara (25.80%), labio (14%) y ojos (8.90%). El 62.60% de las mordeduras fueron causadas por perros familiares. El 47.41% requirió hospitalización, y el 10.63% recibió vacunación antirrábica, concluyendo que, las mordeduras de perro son una causa común de visitas a emergencias, especialmente en niños escolares, y generalmente provienen de perros de la familia.

Background and objectives. Diabetic foot is a debilitating condition that affects approximately 15% of patients with diabetes mellitus (DM) and is frequently complicated by infections. This condition significantly contributes to morbidity and mortality in DM patients. Studies have identified peripheral arterial disease (PAD) and peripheral neuropathy (PN) as significant risk factors for diabetic foot. Therefore, this study aims to determine the prevalence of PAD and PN in infected diabetic foot. Materials and methods. This study included 99 patients diagnosed with DM. Participants were categorized into three groups: no diabetic foot, uninfected diabetic foot, and infected diabetic foot. PAD was assessed using the ankle-brachial index measured with a handheld Doppler device. PN was evaluated using the Semmes-Weinstein 5.07 (10 g) monofilament. Results. The prevalence of PAD was significantly higher in patients with infected diabetic foot (84.8%) compared to those with uninfected diabetic foot (66.7%) and those without diabetic foot (15.2%) (p < 0.001). Similarly, the prevalence of PN was highest among patients with infected diabetic foot (93.9%) (p < 0.001). The coexistence of PAD and PN was most prevalent in patients with infected diabetic foot (78.8%), followed by patients with uninfected diabetic foot (54.5%). Only 6.1% of patients without diabetic foot had both conditions (p < 0.001). Conclusions. The prevalence of PAD and PN was highest in patients with infected diabetic foot compared to those with uninfected diabetic foot or no diabetic foot.

Background. Endoscopic sinus surgery is a well-established surgical procedure for the treatment of chronic rhinosinusitis that does not respond to medical treatment. Conventional surgery is still performed by surgeons. Therefore, it is worthwhile to study and evaluate both methods. Objective. To assess the effectiveness of endoscopic sinus surgery versus conventional surgery for the treatment of chronic maxillary sinusitis. Method. A prospective comparative study of 45 cases of chronic maxillary sinusitis refractory to medical treatment involving patients of different ages and sexes was conducted from January to December 2023 at the AL-Sadder Hospital. Approximately 25 patients underwent conventional surgery, and 20 underwent endoscopic sinus surgery. All patients underwent full history taking, clinical and endoscopic examinations, radiological evaluation, and postoperative follow-up for six months. Results. The male-to-female ratio was 1.5:1. The main complaints were nasal obstruction (62.2%), facial pain (13%), nasal discharge (11.1%), and headaches (8.9%). A total of 45 cases suffering from chronic rhinosinusitis uncured by medical treatment were included in the study. Twenty-five patients were treated with conventional surgery, while 20 were treated with endoscopic surgery. The most common finding was congested mucosa (88.9%), followed by a hypertrophied inferior turbinate (77.8%). Mucopus in the osteomeatal complex (44.4%), polyps (17.8%), and large middle turbinate (11.1%) were the most common endoscopic findings. Conclusion. Chronic sinusitis mainly affects young age groups; nasal obstruction is the most common presentation, followed by facial pain, nasal discharge, and headaches. Conventional surgery is effective when the predisposing factor for sinusitis is septal deviation, whereas endoscopic surgery is effective in cases of osteomeatal unit obstruction.

This study aims to analyze the effect of the application of several concentrations of liquid organic fertilizer based on palm fiber and the composition of plant media on the growth of moringa plants (Moringa oleifera L.). Palm fiber liquid organic fertilizer was chosen because of its potential as a source of environmentally friendly nutrients that can increase plant productivity. The study was conducted using a random group design (RAK) with treatment of various concentrations of liquid organic fertilizer (0%, 15%, 20%, and 25%) as well as variations of plant media by volume (1:1) (top soil, top soil + cocopeat, top soil + husk charcoal, and top soil + compost). The observed growth parameters included plant height, number of leaves, stem diameter, leaf chlorophyll, plant wet weight, leaf wet weight and root wet weight. The results showed that the concentration of liquid organic fertilizer of palm fiber and the composition of the plant media significantly affected the growth of moringa plants. The combination of 20% palm fiber liquid organic fertilizer concentration and top soil + compost (P2M3) provides the best growth results compared to other treatments. These findings provide important insights for the development of more efficient and sustainable moringa cultivation techniques.

Student teachers’ perceptions of artificial intelligence chatbots for classroom practices: An interpretative phenomenological analysis
Authors: Mollo Paseka Patric
Published: February 2025

This paper examines student teachers’ understanding of Artificial Intelligence (AI) chatbots and their application in teaching and learning practices. A qualitative research methodology, specifically Interpretative Phenomenological Analysis (IPA), was employed to explore student teachers’ perceptions of AI chatbots. A purposive sampling strategy was used to select eleven (11) student teachers in their fourth year of study for a B.Ed. degree at the University of Technology in South Africa. To interpret and analyse student teachers’ perceptions of the use of AI chatbots in their teaching and learning practices, data analysis was conducted using Systematic Text Condensation (STC) in a five-step process. The study explored themes aligned with the knowledge dimensions of the Technological Pedagogical Content Knowledge (TPACK) framework. Findings revealed a generally limited understanding among student teachers regarding artificial intelligence, particularly chatbots. Although some learners in schools use chatbots, student teachers still lack the knowledge to utilise these technological systems for teaching practices. This includes, among other things, using AI chatbots to transform classrooms into personalised learning environments for classroom management and student analytics. In a nutshell, an AI chatbot for classroom purposes can serve as a diligent administrative assistant, an Indigenous planner, and enhance pedagogical practices. These findings underscore the need for further research and training to improve student teachers' knowledge and utilisation of AI chatbots in the classroom.

Evaulating the role of EU funding in enhancing Startup growth and adressing egional inequities
Authors: Samardžija Jasminka
Published: February 2025

Startups drive innovation but face funding and expansion challenges, which EU funding aims to address. A research gap exists in evaluating the long-term performance of EU-funded startups, particularly in measuring growth rates, survival rates, and market expansion. The study investigates the research question: To what extent do EU funding programs impact the growth and sustainability of startups across member states? Research hypothesis: (H1) EU funding significantly improves the growth and sustainability of startups, and (H2) significant regional disparities exist, with Northern and Western Europe benefiting more than Eastern and Southern regions. Both hypotheses were confirmed. A quantitative methodology using secondary data sources assessed performance indicators before and after funding. EU funding positively influences startup growth, improving revenue, employment, and sustainability but with persistent regional disparities. The study’s limitations include limited qualitative insights, while recommending region-specific EU funding strategies for balanced growth.

This paper analyzes the entrepreneurial traits of successfulentrepreneurs from both theoretical and empirical perspectives.Qualitative secondary analysis is used to present metrics for determiningthe psychological profile of successful entrepreneurs, specificallyowners of micro-companies. These metrics include the EntrepreneurialSelf-Efficacy Scale, the Entrepreneurial Attitude Scale, and the EntrepreneurialCompetency Model. The psychological profile of successfulentrepreneurs is characterized by key traits such as self-confidence,perseverance, diligence, and patience, which form the foundation forachieving business success and maintaining psychological balance.The primary empirical research in this study examined the psychologicalprofiles of a sample of 100 entrepreneurs from NorthwesternCroatia. The paper tests five hypotheses regarding entrepreneurialtraits and their impact on entrepreneurial success. The findings indicatethat traits such as personal initiative, creativity, openness to newideas, persistence, and a clear business vision significantly contributeto entrepreneurial success. The results support the hypotheses thatpersonal initiative, creativity, and persistence are essential for overcomingchallenges and driving innovation in business. Moreover, theimportance of a clear business vision as a motivational factor underscoresthe necessity for entrepreneurs to maintain a focused and strategicapproach.
Musk’s Tweet effect on Bitcoin and Tesla prices
Authors: Roška Vlasta , Špoljarić Marko
Published: February 2025

Social media significantly impacts the dynamics and move-ment of stock and cryptocurrency markets. The perfect market hypothesis assumes that all available information is already embed-ded in stock prices, meaning that only some announcements will affect the market price of a company’s stock. The efficient market hypothesis and anomalies that cause certain deviations apply to both stock and cryptocurrency markets. Social networks like Twitter, Facebook, and Reddit are significant tools for promoting cryptocurrencies. This paper aims to explore the influence of social media on market price move-ments, using Tesla stock and Bitcoin as examples. The conclusion is that Musk’s Tweet Effect demonstrates an anomaly of market over-reaction and impacts the price movements of Bitcoin and Tesla stocks.

‘But I Was Born for Opposition’
Authors: Beatty Bernard
Published: February 2025

The essay is concerned with Byron as a self-consciously oppositional poet but comes at the question by presenting and trying to understand the character of Victorian opposition to Byron’s opposition. It argues that the main reasons were Byron’s performance of feelings and the relationship of this to a forcefully presented negativity in fundamental areas to which Victorians knew that they had no answers, and which threatened their need to act as though their constant proclamation of moral certainties had some basis. It examines two stanzas from
Childe Harold’s Pilgrimage
III to demonstrate this. It concludes by considering whether we now are better or worse at registering Byron’s oppositional force.

Este artículo reflexiona en torno al rol que han jugado las revistas digitales en el desarrollo de la poesía hispanoamericana en el primer cuarto del siglo XXI. Se parte de un análisis que cuestiona el origen del fenómeno: ¿cómo surgen estás plataformas? ¿En qué contextos literarios? ¿Cómo correlato a cuáles circunstancias sociales? Pero, ante todo, se piensa la emergencia de estas publicaciones a la luz de un distinto modo de vincularse, apropiarse o negar la tradición literaria, es decir, de un nuevo modo de relación con el tiempo y con su tecnología. Esta conciencia de la temporalidad es llamada por el historiador francés François Hartog

A critical history of architectural modernism
Authors: Buras Nir H. , Katona Vilmos , Mehaffy Michael W. , Salingaros Nikos A.
Published: February 2025

Future generations deserve and need an honest accounting of architectural Modernism, and its Neo-Modernist and “Post-Modernist” variants, based on scientific analysis and the factual historical record. Reintroducing traditional tectonic culture and focusing on applying fractal and planar symmetries to design critique provides a more revolutionary account of the Modernist concept, its associated “propaganda”, and the physical legacy of the movement. The authors seek answers to two questions: (1) whether Modernist architecture justly conquered the world by its claimed “Zeitgeist” – or was its success due to other factors; and (2) to what extent Modernism brings about the originally promised cultural and social benefits today. This essay seeks to clear up the ambiguity of the Modernist architectural doctrine through facts, and includes criticisms regarding its massive detrimental impact on the world’s built and natural environments. A growing movement in Europe and elsewhere is challenging the legitimacy of many contemporary architectural designs. These critics attack the persistence of discredited Modernist theory, and the resulting harm to people and our planet. Defenders respond that the members of this movement are ignorant populists who do not understand the legitimate theoretical and cultural foundations of contemporary design. Here we examine this controversy and conclude that a considerable body of scientific evidence supports the critics. By focusing on the choices we do have today, we empower architects to implement drastic changes in new projects.
Improving Radial Velocities by Marginalizing over Stars and Sky: Achieving 30 m s−1 RV Precision for APOGEE in the Plate Era

The radial velocity catalog from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) is unique in its simultaneously large volume and high precision as a result of its decade-long survey duration, multiplexing (600 fibers), and spectral resolution of R ∼ 22,500. However, previous data reductions of APOGEE have not fully realized the potential radial velocity (RV) precision of the instrument. Here we present an RV catalog based on a new reduction of all 2.6 million visits of APOGEE DR17 and validate it against improved estimates for the theoretical RV performance. The core ideas of the new reduction are the simultaneous modeling of all components in the spectra, rather than a separate subtraction of point estimates for the sky, and a marginalization over stellar types, rather than a grid search for an optimum. We show that this catalog, when restricted to RVs measured with the same fiber, achieves noise-limited precision down to 30 m s−1 and delivers well-calibrated uncertainties. We also introduce a general method for calibrating fiber-to-fiber constant RV offsets and demonstrate its importance for high RV precision work in multifiber spectrographs. After calibration, we achieve 47 m s−1 RV precision on the combined catalog with RVs measured with different fibers. This degradation in precision relative to measurements with only a single fiber suggests that refining line spread function models should be a focus in the Sloan Digital Sky Survey V to improve the fiber-unified RV catalog.
Chicago–Carnegie Hubble Program: A Multiwavelength Search for the Effects of Metallicity on the Cepheid Distance Scale. II. Theoretical Models and Synthetic Spectra
Authors: Madore Barry F. , Freedman Wendy L. , Owens Kayla
Published: February 2025

This is the second of two papers exploring the effects of metallicity on the multiwavelength properties of Cepheids in terms of their multiwavelength period–luminosity (PL) relations, impacting their use as extragalactic distance indicators and underpinning one of the most popular paths to estimating the expansion rate of the Universe, H
0. In Paper I, we presented five tests for the influence of metallicity on galactic and extragalactic Cepheid PL relations, spanning nearly 2 dex in metallicity and inspecting PL relations from the optical (BVI), through the near-infrared (JHK), and into the mid-infrared (at 3.4 and 4.5 μm). And in no case were any statistically significant results forthcoming. Here we interrogate published spectral energy distributions constructed from theoretical (static) stellar atmospheres, covering the surface gravity and temperature ranges attributed to classical (supergiant, F and K spectral type) Cepheid variables, and explore the differential effects of changing the atmospheric metallicity, down by 2 dex from solar (a factor of 100 below the average Milky Way value) and then up from solar by 0.5 dex (i.e., a factor of 3× above the Milky Way value). The theoretical models clearly show that metallicity systematically impacts each of the bandpasses differentially: the level of this effect is largest in the ultraviolet (where line blanketing is most intense), reversing sign in the optical (due to flux redistribution from the UV), and then asymptotically falling back to zero from the red to the far-infrared. The discovered effects of metallicity are systematic, but they are small, and as such, they do not contradict the findings of Paper I, but they do explain why the problem has been so hard to resolve given the low level of precision of the photometry for all but the very nearest and apparently brightest Cepheids. The most interesting (and useful) result of this investigation is that from a close examination of the models, we have discovered infrared regions in Cepheid spectral energy distributions that allow for the simultaneous correction for extinction and metallicity differences by the judicious combination of only two filters: one in the near-infrared and one in the mid-infrared, the former centered at 1.2 μm and the other centered at 3.6 μm. Even more exciting and promising is the fact that both of these bands can be simultaneously observed in single exposures using the dual-channel imager, NIRCam on JWST.

IRAS source 19312+1950 (hereafter I19312) is an infrared point source with maser emissions of SiO, H2O, and OH molecules. Although initial observations suggested that I19312 might be an evolved star, its characteristics are not fully consistent with this classification. This study aims to further investigate the nature of I19312 by conducting long-term monitoring of its maser emissions and comparing the results with other known astrophysical objects. We conducted long-term monitoring of SiO, H2O, and OH maser emissions using single-dish radio telescopes. The results were then compared with historical maser data and the characteristics of similar objects to infer the possible origin of I19312. The SiO maser emissions from I19312 were detected over a wide velocity range and exhibited significant time variability. The OH maser lines suggest characteristics of an evolved star, while the H2O maser lines indicate molecular outflows. These features suggest that I19312 could be a candidate for a water fountain star, though there are inconsistencies, such as the large molecular gas mass, that challenge this hypothesis. The possibility of I19312 being a red nova remnant (RNR) is also considered, but this remains speculative due to the lack of direct evidence. The evolutionary stage of I19312 remains unclear, but it shares multiple characteristics with both evolved stars with peculiar properties and RNRs. Further long-term monitoring and high-resolution interferometric observations are required to better constrain the nature of this object.
Inverse Raman Scattering and the Diffuse Interstellar Bands: An Exploration of the Systemic Interconnections between Spontaneous and Inverse Raman Scattering and Extended Red Emission, Red Rectangle Bands, and Diffuse Interstellar Bands
Authors: Zagury Frédéric
Published: February 2025

First identified in 1964, inverse Raman scattering (IRS) is a nonlinear stimulated phenomenon that induces Raman-scattered absorptions where Raman emissions would be expected. This paper highlights the significance of IRS in analyzing the spectra of stars located in the distant background of H I interstellar clouds. Specifically, ultraviolet emission lines Raman scattered by atomic hydrogen, typically observed in emission at wide scattering angles in the optical spectra of symbiotic stars and nebulae, should appear as IRS absorptions in the optical spectra of the background stars. I show that all known interstellar Raman-scattered emission lines in the Hα wavelength region are detected in absorption as diffuse interstellar bands (DIBs) in the spectra of reddened stars, and conclude that IRS by atomic hydrogen resolves the long-standing DIB puzzle. This sheds new light on the perplexing relationship between DIBs and the Red Rectangle nebula emission bands (RRBs). The conditions under which either DIBs or RRBs are detected emphasize the importance of considering the physical relationship between the observer, the H I medium, and the direction of the illuminating radiation field (i.e., the geometry of the observation) in observations of H I interstellar matter. Observing in the direction of the radiation field or on its side determines whether IRS, yielding DIBs and the 2200 Å bump, or spontaneous Raman scattering at wide scattering angles, resulting in extended red emission, Raman-scattered emission lines (including RRBs), and unidentified infrared bands, will be observed.

The velocity distribution functions (VDFs) of He+ pickup ions (PUIs) through two interplanetary coronal mass ejection (ICME) events associated with two interplanetary shocks are examined. Their specific properties in pitch-angle space were used as tracers of the local physical processes. These VDFs were studied using observations from the PLasma And SupraThermal Ion Composition instrument on board the Solar Terrestrial Relations Observatory with 10 minutes cadence and full energy and angular resolutions. The analysis focuses on pitch angle distributions and their average/deviation to evaluate heating/cooling, acceleration/deceleration, and pitch angle diffusion. For an ICME accompanied by the quasi-perpendicular shock, (a) reflected and energized particles were found in the upstream, and pitch angle scattering and suprathermal particle production were conspicuous in the downstream; (b) strong heating was observed in the sheath region; (c) suprathermal particles were found in the sheath region and attributed to the velocity fluctuation within the solar wind; and (d) universal pitch angle scattering was found throughout the ICME. For an ICME accompanied by a quasi-parallel shock, (a) localized heating and acceleration were found around the shock location; (b) power-law suprathermal tail distributions were found near the shock, suggesting diffusive shock acceleration processes; (c) weak or no sheath heating was observed; and (d) pitch angle scattering was correlated with magnetic field power spectral density. In the magnetic cloud for this event, pitch angle diffusion consistent with the scattering by counterpropagating Alfvén waves was found. This type of analysis can be applied to study shock injection processes and PUI transport/diffusion processes under active conditions.

We report the GeV γ-ray emission around the composite supernova remnant (SNR) CTB 87 with more than 16 yr of PASS 8 data recorded by the Fermi Large Area Telescope. Two separate point sources with different GeV spectra are identified in this region: one has a soft γ-ray spectrum, likely due to interactions between the SNR shock and molecular clouds, and another source with a hard GeV γ-ray spectrum aligns with the TeV spectrum of VER J2016+371, suggesting it as the GeV counterpart. Considering the observations of CTB 87 in the radio and X-ray bands, VER J2016+371 is proposed to originate from the pulsar wind nebula (PWN) associated with PSR J2016+3711. A leptonic model with a broken power-law electron distribution could explain the multiwavelength data of VER J2016+371, with fitted parameters matching typical γ-ray PWNe. Deeper searching for the SNR shock of CTB 87 in other bands and the future TeV observations by LHAASO and Cherenkov Telescope Array are crucial to reveal the nature of CTB 87.

Using spatially resolved spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory sample, we investigate the parameters influencing the radial gradients of gas-phase metallicity (

) to determine whether disk formation is primarily driven by coplanar gas inflow or by the independent evolution of distinct regions within the disk. Our results show that

strongly correlates with local gas-phase metallicity at a given stellar mass, with steeper gradients observed in metal-poorer disks. This trend supports the coplanar gas inflow scenario, wherein the gas is progressively enriched by in situ star formation as it flows inward. In contrast, the radial gradient of stellar mass surface density shows very weak correlations with

The current study focuses on the stem and flowers of Linum hologynum, an endemic species to the Balkan Peninsula, a potential source of valuable metabolites. L. hologynum is poorly studied in any aspects, including its phytochemistry and pharmacological activity. Applying various chromatographic techniques, two isomeric C-glycosylflavones were isolated. Structures were elucidated, by means of spectroscopic methods, including 1H and 13C NMR as well as LC-HRESI-MS analysis, as orientin and isoorientin. This is the first report of those metabolites from L. hologynum.

Published: February 2025

Food allergies can significantly impact school-age children and the teachers and staff who interact with children. A nurse educator used materials from the Food Allergy Research & Education (FARE, 2019) to provide an educational intervention at a parochial urban school to help school staff and administrators become better prepared to manage students with food allergies. Academic training on allergy knowledge, attitudes, and beliefs was provided to non-medical staff at the school. The educational intervention impacted participants' knowledge and understanding of food-related policy development. As food allergies continue to rise in school-age children, coupled with the decrease in school nurses, the need for this type of intervention will expand. A nurse educator-led food allergy intervention could ensure informed staff caring for school children with allergies.
