Background: Antimicrobial resistance is a global threat to public health. Pseudomonas aeruginosa Pan Drug-Resistant requires the latest antimicrobials. This limitation of therapy requires a breakthrough in the treatment of this infection. Combining antimicrobials with a synergistic effect is thought to increase the cure rate in clinical use. This study aimed to determine the synergistic effect of several combinations of anti-pseudomonas antibiotics against Pan Drug-Resistant Pseudomonas aeruginosa in an in vitro test using the AZDAST method.
Method: An Antibiotic combination test was carried out using the AZDAST method to assess in vitro synergistic activity. The antibiotic single disk used was Amikacin 30 µg, Ceftazidime 30 µg, Meropenem 10 µg, Ciprofloxacin 5 µg; double disk antibiotic is Amikacin 30 µg, Ceftazidime 30 µg, Meropenem 10 µg, Ciprofloxacin 5 µg and combination antibiotic disks Amikacin 30 µg-Ceftazidime 30 µg, Amikacin 30 µg-Meropenem 10 µg, Amikacin 30 µg-Ciprofloxacin 5 µg in which two antibiotic paper disks are combined stacked together, with a 24 mm gap between the other antibiotic combinations.
Result: The results showed that combining the four antibiotics had a synergistic effect. The zone of inhibition resulting from testing the combination of several antibiotics against Pan Drug Resistant Pseudomonas aeruginosa showed no statistical significance (p > 0.05) compared to all antibiotics and comparisons in the combination group of antibiotics only.
Conclusion: The combination of anti-pseudomonas antibiotics synergizes with Pan Drug-Resistant Pseudomonas aeruginosa in the AZDAST method in vitro test.
Análisis bromatológico de la harina de papachina (Colocasia esculenta): una alternativa alimenticia de alto contenido proteico y nutricional para las familias del Chocó Biogeográfico
Authors: Perea Murillo Mirla
Published: June 2024

La conservación de especies vegetales alimenticias y la transformación de materia primas constituyen una alternativa sostenible para el desarrollo de las comunidades en el municipio de Guapi, Cauca, Colombia. Se examinó la composición nutricional de la harina de papachina (Colocasia esculenta) con la finalidad de conocer un poco más sus características fisicoquímicas mediante la evaluación de variables como niveles de proteína, humedad, fibra cruda, cenizas, lignina, celulosa y hemicelulosa. Los resultados arrojaron que la harina de C. esculenta posee un alto contenido de proteína (27,2 g/kg), humedad (43,1 g/kg), fibra cruda (52,7 g/kg), cenizas (23 g/kg), lignina (12,8 g/kg), celulosa (7,9 g/kg) y hemicelulosa (536 g/kg), valores que se consideran superiores a los encontrados en la harina de otros tubérculos como la papa, ñame y la yuca. El hallazgo de altos contenidos nutricionales ricos en proteínas y minerales en C. esculenta la convierten en un alimento muy saludable, incluso más que otros que tienen capacidad de comercialización en el mercado; sumado a ello, sus características fisicoquímicas, así como su perfil mineral, permiten sugerir el uso de la harina para el desarrollo de productos tanto de consumo humano (panes, galletas, entre otros), como animal, sustituyendo parcialmente las harinas de insumos no producidos en Colombia.

Con la finalidad de evaluar la diversidad, distribución y el rol funcional de la entomofauna asociada con un cultivo de guanábana (Annona muricata, Annonaceae) en la vereda San Antonio, municipio de Quibdó, se llevaron a cabo 20 muestreos que incluyeron capturas manuales y con jamas entomológicas en distintas partes de la planta, como hojas (H), tallo (T), fruto (F), flor (Fl) y ramas (R). Se realizaron análisis descriptivos para cada etapa fenológica, calculando el número total de especies (S), el número total de individuos (N), y los índices de diversidad. Se colectaron 1.627 insectos pertenecientes a cinco órdenes, 31 familias y 53 géneros. Los órdenes con mayor representación fueron: Hymenoptera (S=17) y Hemiptera (S=14). El género predominante fue Atta con 323 individuos (21,5%). Las hojas fueron la parte de la planta que presentó la mayor diversidad de géneros e individuos. En cuanto a la fenología de la planta, se observó la mayor riqueza durante la floración (S=34), representando 38,6% del total. La riqueza estimada indicó que se registró 67% de la entomofauna, sugiriendo que el muestreo no fue completamente representativo. Finalmente, los insectos se clasificaron en cinco gremios alimenticios, destacando la preeminencias de los fitófagos con 34 géneros (64,2%) y 1.134 individuos (75,4%) en términos de riqueza y abundancia. De todos los géneros registrados 66% son considerados plagas (fitófago y polífago), mientras que 26,4% fueron catalogados como benéficos (depredadores, polinizadores, saprófago, necrófaga y polífago).
La participación de las mujeres negras en proyectos productivos en Bojayá,Chocó: problemáticas, resistencias y posibilidades
Authors: Lozano Mayo Luz América , Cano Wilmar Alexander
Published: June 2024

Este artículo tiene la intención de indagar sobre las diferentes instancias de participación de las mujeres negras de las comunidades de La Loma, Piedra Candela y Pogue en Bojayá (Chocó, Colombia). El texto analiza, por una parte, la forma como las mujeres negras se integran y participan en los proyectos e iniciativas de desarrollo productivo y rural, y por otra, los discursos y perspectivas que sustentan estas iniciativas productivas de desarrollo, así como las prácticas y estructuras socioculturales y económicas que estos proyectos reproducen o legitiman. Mediante diversas reuniones generales, talleres y entrevistas semiestructuradas con las mujeres negras de estas comunidades, se realiza una revisión y crítica de los conceptos de desarrollo, género y etnia en la medida en que su vinculación con proyectos asistencialistas y productivos en la región resulta problemática. El artículo muestra, primero, que muchos de es- tos proyectos están sustentados en concepciones desarrollistas y coloniales, pero también patriarcales en la medida en que asumen una representación de las mujeres negras como pasivas y víctimas de las condiciones socioeconómicas, y segundo, que los proyectos presentan problemas de base, pues son formulados de manera genérica, no tienen en cuentan las perspectivas de las mismas mujeres, lideresas o miembros de las comunidades, no son pertinentes para el territorio y no tienen continuidad, por lo que prontamente terminan desilusionando. No obstante, las mujeres negras asumen estos proyectos productivos como posibilidades de cambio y, por tanto, esperan impactos positivos y efectivos a mediano y largo plazo en el mejoramiento de sus condiciones de vida. El texto concluye con las nuevas oportunidades y posibilidades que se abren para las mujeres gracias a la apropiación y circulación por espacios no domésticos, las nuevas instancias de participación y toma de decisiones, y con la consecución de independencia financiera.

Forecasting contrail climate forcing for flight planning and air traffic management applications: The CocipGrid model in pycontrails 0.51.0
Authors: Engberg Zebediah , Teoh Roger , Abbott Tristan , Dean Thomas , Stettler Marc E. J. , Shapiro Marc L.
Published: June 2024

Abstract. The global annual mean contrail net radiative forcing may exceed that of aviation’s cumulative CO2 emissions by at least two-fold. As only around 2–3 % of all flights are likely responsible for 80 % of the global annual contrail climate forcing, re-routing these flights could reduce the formation of strongly warming contrails. Here, we develop a contrail forecasting model that produces global predictions of persistent contrail formation and their associated climate forcing. This model builds on the methods of the existing contrail cirrus prediction model (CoCiP) to efficiently evaluate infinitesimal contrail segments initialized at each point in a regular 4D spatiotemporal grid until their end-of-life. Outputs are reported in a concise meteorology data format that integrates with existing flight planning and air traffic management workflows. This “grid-based” CoCiP is used to conduct a global contrail simulation for 2019 to compare with previous work and analyze spatial trends related to strongly warming/cooling contrails. We explore two approaches for integrating contrail forecasts into existing flight planning and air traffic management systems: (i) using contrail forcing as an additional cost parameter within a flight trajectory optimizer; or (ii) constructing polygons of airspace volumes with strongly-warming contrails to avoid. We demonstrate a probabilistic formulation of the grid-based model by running a Monte Carlo simulation with ensemble meteorology to mask grid cells with significant uncertainties in the simulated contrail climate forcing. This study establishes a working standard for incorporating contrail mitigation within existing flight planning and management workflows and demonstrates how forecasting uncertainty can be incorporated to minimize unintended consequences associated with increased CO2 emissions of avoidance.

Abstract. The Energy Exascale Earth System Model (E3SM) Land Model (ELM) is a state-of-the-art land surface model that simulates the intricate interactions between the terrestrial land surface and other components of the Earth system. Originating from the Community Land Model (CLM) version 4.5, ELM has been under active development, with added new features and functionality, including plant hydraulics, radiation-topography interaction, subsurface multiphase flow, and more explicit land use and management practices. This study integrates ELM v2.1 with the Weather Research and Forecasting (WRF) Model through a modified Lightweight Infrastructure for Land Atmosphere Coupling (LILAC) framework, enabling affordable high-resolution regional modeling by leveraging ELM’s innovative features alongside WRF’s diverse atmospheric parameterization options. This framework includes a top-level driver for variable communication between WRF and ELM and Earth System Modeling Framework (ESMF) caps for WRF atmospheric component and ELM workflow control, encompassing initialization, execution, and finalization. Importantly, this LILAC-ESMF framework demonstrates a more modular approach compared to previous coupling efforts between WRF and land surface models. It maintains the integrity of the ELM’s source code structure and facilitates the transfer of future developments in ELM to WRF-ELM. To test the ability of the coupled model in capturing land-atmosphere interactions over regions with a variety of land uses and land covers, we conducted high-resolution (4 km) WRF-ELM ensemble simulations over the Great Lakes Region (GLR) in the summer of 2018 and systematically compared the results against observations, reanalysis data, and WRF-CTSM (WRF-coupled with the Community Terrestrial Systems Model). In general, the coupled WRF-ELM model has reasonably captured the spatial distribution of surface state variables and fluxes across the GLR, particularly over the natural vegetation areas. The evaluation results provide a baseline reference for further improvements of ELM in the regional application of high-resolution weather and climate predictions. Our work serves as an example to the model development community for expanding an advanced land surface model’s capability to represent fully-coupled land-atmosphere interactions at fine spatial scales. The development and release of WRF-ELM marks a significant advancement for the ELM user community, providing opportunities for fine-scale regional representation, parameter calibration in coupled mode, and examination of new schemes with atmospheric feedback.
Equilibrium distance from long-range dune interactions

Published: June 2024

Abstract. Flow perturbations induced by dune topography affect sediment transport locally, but can also be felt over long distances altering the dynamics of isolated neighbouring dunes downstream. In order to work under optimal conditions that eliminate transverse flow components, collisions and mass exchange between dunes, we study here these long-range interactions using a 2D numerical model where two equal-sized dunes lying on a non-erodible bed are exposed to a symmetric reversing flow. Depending on the initial spacing, dunes either attract or repel each other, to eventually converge towards a steady-state spacing. This equilibrium distance decreases with flow strength and increases with period of flow reorientation and dune size. It is mainly controlled by the reversing dune shape and the structure of the turbulent wake it generates, which continuously modulates the mean shear stress on the downstream dune. Under multi-directional wind regimes, these long-range flow perturbations offer an alternative mechanism for wavelength selection in dune fields with non-erodible interdune areas. Within these dune fields, estimates of mean shear stress could be used to assess the relative migration rate and the state of attraction/repulsion between neighbouring dunes.

Abstract. In the last two decades UK research institutes have led a wide range of developments in marine data assimilation (MDA), covering areas from the MDA applications in physics and biogeochemistry, to MDA theory. We review the progress over this period and formulate our MDA vision for both the short-term and the longer-term future. We focus on identifying the MDA stakeholder community and current/future areas of impact, as well as the current trends and the future opportunities. This includes rapid growth of machine learning (ML) / artificial intelligence (AI) and digital twin applications. We articulate the MDA needs for future types of observational data (whether planned missions, or hypothetical) and what should be the response of the MDA community to the increase in computational power and new computer architectures (e.g. exascale computing). Although the specifics depend on the MDA area, we advocate for balanced redistribution of the new computational capability among increased model resolution, model complexity, more sophisticated DA algorithms and uncertainty representation (e.g. ensembles). We also advocate for integrated approaches, such as strongly coupled DA (ocean/atmosphere, physics/biogeochemistry, ocean/sea ice) and the use of ML/AI components (e.g. for multivariate increment balancing, bias-correction, model emulation, observation re-gridding, or fusion).
Responses of microbial metabolic rates to non-equilibrated silicate vs calcium-based ocean alkalinity enhancement
Authors: Marin-Samper Laura , Arístegui Javier , Hernández-Hernández Nauzet , Riebesell Ulf
Published: June 2024

Abstract. This study contributes to the inaugural exploration of non-equilibrated Ocean Alkalinity Enhancement (OAE). The manipulation of Total Alkalinity (TA), involving silicate and calcium-based ∆TA gradients ranging from 0 to 600 µmol · L-1, was conducted without prior CO2 sequestration, under natural conditions and at a mesocosm scale (~60 m3). The resulting impact included an increase in pH and a decrease in pCO2, sustained across the experiment, as full natural equilibration via sea-gas exchange did not occur. Implemented in a neritic system under post-bloom conditions, a midway mixing event was simulated. Following an inorganic nutrient addition, discernible delays in bloom formation, as indicated by the Gross Production (GP) and Net Community Production (NCP) rates, as well as by the chlorophyll-a (Chla) concentrations, in relation to the ∆TA gradient, were observed. Notably, the delay was more pronounced for the calcium treatment set compared to the silicate one, where low TA treatments exhibited earlier responses than high TA ones. This delay is likely attributed to the previously documented, species-specific negative relationships between high pH/lowCO2 levels and phytoplankton growth rates. This study underscores the need for further investigation into the implications of this response pattern in terms of trophic transfer and seasonal suitability. Further, it is anticipated that a wider delay in bloom formation would be evident with a larger non equilibrated TA gradient. Thus, highlighting the importance of exploring variations in TA limits for a comprehensive understanding of the OAE’s impacts.
Technical note: A low-cost, automatic soil-plant-atmosphere enclosure system to investigate CO2 and ET flux dynamics

Published: June 2024

Abstract. Investigating greenhouse gases (GHG) and water flux dynamics within the soil-plant-atmosphere-interphase is a key for understanding ecosystem functioning, as these dynamics reflect the ecosystem's responses to environmental changes. Understanding these responses is hence essential for developing sustainable agriculture systems that can help to adapt to global challenges such as inter-alia increased drought. Typically, an initial understanding of GHG and water flux dynamics is gained through laboratory or greenhouse pot experiments, where gas exchange is often measured using commercially available, manual closed (leaf) chamber systems. However, these systems are usually rather expensive and often labor-intensive, thus limiting the number of different treatments that can be studied and their repetitions. Here, we present a fully automatic, low cost (<1.000 Euro), multi-chamber system based on Arduino, termed “greenhouse coffins”. It is designed to continuously measure canopy CO2 and evapotranspiration (ET) fluxes. And it can operate in two modes: an independent and a dependent measurement mode. The independent measurement mode utilizes low cost NDIR CO2 (K30 FR) and relative humidity (SHT31) sensors, thus making each “greenhouse coffin” a fully independent measurement device. The dependent measurement mode connects multiple “greenhouse coffins” via a low cost multiplexer (< 250 Euro) to a single infrared gas analyzer (LI-850, LI-COR Inc., Lincoln, USA), allowing for measurements in series, achieving cost efficiency, while also gaining more flexibility in terms of target GHG fluxes (potential extension to N2O, CH4, stable isotopes). In both modes, CO2 and ET fluxes are determined through the respective concentration increase during closure time. We tested both modes and demonstrated that the presented system is able to deliver precise and accurate CO2 and ET flux measurements using low cost sensors, with an emphasis on calibrating the sensors to improve measurement precision. Through connecting multiple greenhouse coffins via our low cost Multiplexer to a single infrared gas analyzer in the dependent mode, we could show moreover that the system can efficiently measure CO2 and ET fluxes in a high temporal resolution across various treatments with both labor and cost efficiency. Therefore, the developed system offers a valuable tool for conducting greenhouse experiments, enabling comprehensive testing of plant-soil dynamic responses to various treatments and conditions.
Threats Related to Open Geospatial Data in the Uncertain Geopolitical Environment
Authors: Nikander Jussi , Jama Teemu , Tenkanen Henrikki
Published: June 2024

Abstract. During the last few decades, there has been increasing interest in open data, especially with regards to the public sector. Open data promotes transparency in the society, and the availability of data creates significant additional value. There are also potential threats associated with open data. After the Russian invasion of Ukraine, threats to society and national security related to open data have been given a lot more attention than before. Here, we conducted group interviews with a number of security experts in Finland to investigate potential threats related to open data and society. Based on the interviews, we created a number of threat scenarios that were further refined and discussed with experts. We recognized a large number of different potential malicious actors, ranging from hostile nations to individual criminals. The threats these actors might cause are varied, and for many, the best ways to mitigate the threat are not, in fact, related to open data themselves. In addition, changes to open datasets can have significant side effects that also need to be taken into account when considering how to manage the potential threats. Our study concludes that decisions to open new datasets, or to modify already existing ones, need to be made with care, and threat and risk assessment must always be weighted against benefits of publishing the data, as well as drawbacks of leaving the data unpublished.
Geometrically guided and confidence-based point cloud denoising
Authors: Youssefi David , Derksen Dawa , Migel-Arachchige Damien , Siefert Jasmin , Dumas Loïc , Guinet Jonathan
Published: June 2024

Abstract. The generation of photogrammetric point clouds from satellite images is often based on image correlation techniques. Correlation errors can arise for a wide variety of reasons: transient objects, homogeneous areas, shadows, and surface discontinuities. Therefore, a simple 3D Gaussian distribution at the point cloud level is not an appropriate model. In this paper, we propose a new point cloud denoising method integrated into the Multiview Stereo Pipeline CARS, dedicated to satellite imagery. Building upon bilateral filtering principles, our approach introduces a novel utilization of color information, confidence estimation and geometric constraints alongside point positions and normals. While the use of point color increases the level of detail, the addition of geometric constraints and confidence awareness guides processing towards a realistic solution. We propose an ablation study and compare our solution against a previously established bilateral filter with LiDAR data as ground truth.

Authors: Di Leo Margherita , Bacco Manlio , Kona Albana , Minghini Marco
Published: June 2024

Abstract. This work proposes a framework for Earth Observation (EO) cloud platforms to carry out a self-assessment from a user experience perspective. The study outlines the methodological approach used to develop the framework, including the classification of existing EO platforms through a literature review of EU-funded projects. Additionally, a survey on user experience was conducted to further inform the design of the framework. We consider as target users the developers of policy-relevant use cases. The final phase of the methodology identifies user requirements across ten dimensions within the EO value chain and suggests a range of indicators to facilitate self-assessment. The paper emphasises the need to address the identified challenges and limitations to improve the usability and user satisfaction of existing EO cloud platforms. It also highlights the importance of principles such as FAIR (findability, accessibility, interoperability, and reusability) and TRUST (transparency, responsibility, user focus, sustainability and technology), open source components, and Open Geospatial Consortium (OGC) standards in shaping the future of EO data platforms and infrastructures.

Authors: Gaspari Federica , Ioli Francesco , Barbieri Federico , Bonora Samuele , Fascia Rebecca , Pinto Livio , Migliaccio Federica
Published: June 2024

Abstract. Teaching experience in geomatics heavily relies on hands-on activities, but field surveys for educational purposes are usually conducted in controlled environments without proper connection to real-world scenarios. Combining the widespread availability of low-cost equipment with the potential of Free and Open Source Software for Geospatial (FOSS4G) in innovative teaching programmes can fill the gap in preparing young professionals in geomatics and surveying for real-world problems and global challenges, including climate change. This paper presents the active learning experience of the Belvedere Glacier Summer School organized annually by the Department of Civil and Environmental Engineering of Politecnico di Milano in the Italian Alps. During the week-long programme of theoretical and practical sessions, students from different backgrounds, ranging from Engineering to Architecture and Geoinformatics, transform knowledge into skills by designing and carrying out surveys focused on monitoring the evolution of the glacier volume, using GNSS and UAV photogrammetry, and familiarising with 2D and 3D data processing. In a peer-led environment, participants also contribute to the production of open data (orthophotos, DSM and point measurements) published in Zenodo, fostering teamwork and collaboration not only internally but also with the wider research community.
Benefits and Pitfalls of Emotional and Mobility Meb Mapping. A Case Study of Two Czech Cities
Authors: Horak Jiri , Koktava Nikola , Zajac Martin , Kukuliac Pavel , Maresova Petra
Published: June 2024

Abstract. The aim of the paper is to describe the advantages and weaknesses of participatory mapping and to compare them with a questionnaire survey. This case study focuses on two medium-sized cities and their surrounding municipalities, Ostrava (OV) and Hradec Kralove (HK), both located in the Czech Republic. The study works with a questionnaire survey from the research agency STEM/MARK (n=536, PAPI method 86%, CAWI method 14%) from 2022. The main objective of this research was to find out the mobility goals of seniors. Overall, respondents reported 479 goals, with respondents identifying 23 types of important goals in HK and 24 types in OV, with shopping (37 and 24% respectively), doctor (19 and 22%), family (10 and 13%), walking (8 and 6%) and friends (5 and 4%) identified as top priorities. Maximum clustering was assessed at a distance of 370 m for web mapping targets (p<0.05). Survey targets reached maximum clustering at a distance of 140 m in HK and 200 m in OV (p<0.05). The results of web mobility mapping show that natural places and parks are the most common attractive places for respondents. On the other hand, in OV, locations with noisy people or homeless people, as well as industry and brownfields, are identified as repulsive places. In HK, roads, traffic and some public buildings are perceived as the main repulsive places. The perception of railway stations is ambiguous. This study contributes to the discussion on the validity of participatory mapping, showing the importance of careful survey design and data preprocessing. The results from the web mapping were compared with the results from the questionnaire survey (PAPI method) to better describe the advantages and weaknesses of web mapping.

Abstract. Traditional map projections introduce distortions, especially for global data. Discrete Global Grid Systems (DGGS) offer an alternative by dividing the Earth into equal-area grid cells at different resolutions. This paper describes xdggs, a new Xarray extension that simplifies working with DGGS. Xdggs provides a unified API for various DGGS libraries and integrates seamlessly with the Pangeo ecosystem through extending the widely used Xarray library to use the DGGS-specific cell identifiers as an index. This development makes DGGS more accessible and will lead to facilitating data analysis on a planetary scale.Xdggs aims to provide a user-friendly API that hides the implementation complexities of different DGGS libraries. And because it integrates seamlessly with Xarray, a popular tool for geospatial data analysis, xdggs promotes FAIR data practices by simplifying data access and interoperability and can become a valuable tool for geospatial scientists and application developers working with global datasets.
Pan-European open building footprints: analysis and comparison in selected countries
Authors: Minghini Marco , Thabit Gonzalez Sara , Gabrielli Lorenzo
Published: June 2024

Abstract. This paper presents a comprehensive analysis of four non-governmental open building datasets available at the European Union (EU) level, namely OpenStreetMap (OSM), EUBUCCO, Digital Building Stock Model (DBSM) and Microsoft’s Global ML Building Footprints (MS). The objective is to perform a geometrical comparison and identify similarities and differences between them, across five EU countries (Belgium, Denmark, Greece, Malta and Sweden) and various degrees of urbanisation from rural to urban. This is done in a two-step process: first, by comparing the total number and the total areas of building polygons for each dataset and country; second, by intersecting the building polygons and calculating the fraction of the area of each dataset represented by the intersection. Results highlight the influence of urbanisation on the dataset coverage (with increasing completeness when moving from rural to urban areas) and the varying degrees of overlap between the datasets based on a number of factors, including: the amount and up-to-dateness of the input sources used to produce the dataset; the presence of an active OSM community (for OSM and the datasets based on OSM); and the accuracy of Machine Learning algorithms for MS. Based on these findings, we provide insights into the strengths and limitations of each dataset and some recommendations on their use.
Masculinidad y autopercepción en el siglo XIX: Francisco de Asís de Borbón a través de su correspondencia
Authors: Colás Loricera Félix
Published: June 2024

El objetivo de este trabajo es analizar la correspondencia conservada de Francisco de Asís de Borbón, utilizando estas fuentes como herramienta de comprensión de la personalidad del rey consorte. La metodología, centrada en el análisis de contenidos, ha dado como resultado una argumentación dividida en tres etapas: juventud, matrimonio y reinado y exilio. Como conclusiones, se llegan a comprender rasgos diversos de la personalidad del rey. El estudio refleja una configuración de la masculinidad del rey caracterizada por una concepción alejada de las convenciones de la masculinidad normativa, que se obtiene a partir de la exploración de seis categorías: las autodescripciones y el autoanálisis; las reacciones personales y significados otorgados ante sucesos y escándalos de la época; las descripciones de personas (distinguiendo entre varones y mujeres); las descripción de sus relaciones, las críticas, ataques y sátiras o visiones externas de su personalidad y los recursos retóricos que revelan su visión. Este trabajo contribuye a comprender las raíces del sistema binario de género y de la noción de homosexualidad que dominaron el siglo XX. El siglo XIX está marcado por la difusión de dichas nociones en términos más ambiguos que, no por ello, dejan de tener entidad para la investigación, como se observa en este artículo con el caso de Francisco de Asís de Borbón, rey consorte por su matrimonio con Isabel II y paradigmático ejemplo de dicho panorama.
La performance como rastro efímero y queer en el filme La mala educación (2004) de Pedro Almodóvar
Authors: Pucci Valentina
Published: June 2024

Este trabajo analiza la escena icónica de La mala educación (2004), dirigida por Pedro Almodóvar, donde Gael García Bernal interpreta a Zahara en un número drag imitando a Sara Montiel. Desde la perspectiva de los estudios de performance, se examina cómo Almodóvar destaca lo artificioso y vindicativo de lo queer, dialogando con la noción de "rastro efímero queer" de José Muñoz (2019). El análisis se centra en los desafíos que supone la película para las representaciones binarias de género, así como estereotipos y normas estéticas, utilizando para ello conceptos de performance, gesto y fenomenología. Se exploran las construcciones de identidad a través de la figura de Sara Montiel, considerando la sensualidad en el contexto cultural hispanohablante, la industria cinematográfica estadounidense y el periodo posdictatorial en América Latina y España. En conclusión, los diferentes análisis propuestos revelan como resultados las complejas capas de significado entrelazadas en la representación de género tras los ejercicios de travestismo alojados en el film. Por otro lado cómo la construcción de identidades queer responde a las dinámicas de una mirada construida mayoritariamente para un público patriarcal. Y por último, cómo el director combina ambas lecturas con la memoria sobre la agresión y represión ocurridas durante el régimen dictatorial franquista.

The present paper outlines a strategy for computation of weighting factor (x) to compute the peak discharge for a given rainfall runoff event in a basin. The time invariant instantaneous unit hydrograph (IUH) was converted into unit hydrograph (UH) for each storm event. The peak and time to peak of runoff discharge are estimated for different storms of the basin by convolution of UH with rainfall excess (Re). The relative weights of the storm characteristics and basin parameters are also used in the prediction of peak. The Chaukhutia watershed of Ramganga reservoir catchment was selected to check the predicted results with respect to observed direct runoff hybrographs (DRHs). The theory provided excellent agreement for the basin (452 km2) area at the x value 0.30.

The principle of equitable water distribution is to supply predetennined quantity of water at scheduled time. The equity may be on the basis of distribution of operating time of outlets and volume of water in proportion to the size of holding, or in proportion to the requirements of beneficiaries. Software EQUITA was developed to prepare rosters for equitable water distribution in outlet command areas, within the overall framework of rotational· water distribution system. Different levels of equity require different amount of data regarding beneficiaries, their land holdings, watercourses, conveyance losses and the crops grown. The developed software EQUITA can be used to prepare rosters for water distribution for beneficiaries of outlet command areas to achieve desired equity, based on the availability of data.

Lung cancer is the leading cause of cancer mortality world-wide. Cigarette smoking is the most established risk factor for lung carcinogenesis; however, the effects of benzo (a) pyrene [B(a)P], one of the key carcinogens in smoke, on the progression of lung cancer are obscure. The identification of key regulatory and molecular mechanisms involved in lung carcinogenesis is, therefore, critical to understanding this disease and could ultimately lead to targeted therapies to improve prevention and treatment. In an earlier study, I observed the effect of curcumin on the changes in the activities of endogenous antioxidants and lipohydroperoxide in rat lung injury by the administration of B(a)P. In the present study, I am interested in investigating whether B(a)P produces ROS, which activates inflammatory mediators and Wnt/β-catenin signaling to produce a lot of transcriptional genes and biochemical changes involved in lung carcinogenesis and its mechanistic prevention by the targeting of liposomal curcumin in rat.
A Decision Tree Algorithm in University Laboratory Hazardous Chemicals Management and Alternative Technology Research
Authors: Yunan Zhang
Published: June 2024

Laboratory-based research activities include inherent hazards associated with managing hazardous chemicals and processes, requiring comprehensive risk assessment protocols to prevent accidents and injuries. In this study, we investigate the effectiveness of decision tree (DT) algorithms in detecting possible hazards in laboratory work using previous accident documents. The dataset consists of accidents and near-miss incidents reported from various university laboratory operations. Each report describes the nature of laboratory operations and related hazards. In our proposed model, we employ a Word2Vec-based DT algorithm, where Word2Vec transforms words into semantic vectors. The DT algorithm then utilizes these vectors to estimate hazard probabilities by recursively partitioning the data according to their characteristics for predicting the risks associated with university laboratory work. The proposed detection model has been implemented in a Python program. In the results assessment phase, we evaluate our proposed model's effectiveness in forecasting various chemical hazardous situations using numerous evaluation metrics such as recall, f1 score, precision and accuracy. We also carried out a comparison analysis with other traditional approaches. Our experimental findings demonstrate the reliability of the recommended framework.

Viêm khớp thiếu niên tự phát thể hệ thống (Systemic Juvenile Idiopathic Arthritis-sJIA) là một bệnh tự viêm hiếm gặp ở trẻ em, với các triệu chứng sốt, viêm khớp và ít nhất một trong các biểu hiện sau: phát ban, nổi hạch toàn thân, gan to và/hoặc lách to, và viêm thanh mạc. Tuy nhiên, các triệu chứng lâm sàng ban đầu thường không đặc hiệu, dễ nhầm lẫn với các tình trạng bệnh lý khác. Tiêu chuẩn chẩn đoán sJIA của Hiệp hội Thấp khớp học Quốc tế năm 2001 đang được sử dụng hiện nay còn nhiều hạn chế trong chẩn đoán các ca bệnh không điển hình do đó gần đây, tiêu chuẩn Yamaguchi đã được áp dụng để chẩn đoán sớm sJIA. Chúng tôi báo cáo một trường hợp bệnh nhân 14 tuổi với biểu hiện sốt kéo dài kèm tổn thương ban da điển hình. Bệnh nhân được loại trừ các căn nguyên gây sốt khác và đủ tiêu chuẩn chẩn đoán sJIA theo tiêu chuẩn Yamaguchi. Kết luận: Ca bệnh minh hoạ việc áp dụng tiêu chuẩn Yamaguchi trong chẩn đoán sớm các trường hợp sJIA, giúp điều trị kịp thời và ngăn chặn các biến chứng nguy hiểm tính mạng.

Nghiên cứu được thực hiện nhằm đánh giá độc tính cấp và bán trường diễn theo đường uống của dung dịch EATWELLB trên động vật thực nghiệm. Nghiên cứu độc tính cấp được tiến hành trên chuột nhắt trắng chủng Swiss theo đường uống và xác định liều gây chết 50% chuột (lethal dose, LD50) theo phương pháp Litchfied-Wilcoxon. Nghiên cứu độc tính bán trường diễn tiến hành theo hướng dẫn của Tổ chức Y tế Thế giới. Chuột cống trắng chủng Wistar được uống EATWELLB liều 1,8 mL/kg và 5,4 mL/kg trong 4 tuần liên tục. Kết quả nghiên cứu độc tính cấp cho thấy EATWELLB liều 75mL dung dịch gốc/kg không gây biểu hiện độc tính cấp. Như vậy, liều dung nạp tối đa của EATWELLB cao gấp 20,8 lần liều dùng dự kiến trên người không gây độc tính cấp. Chưa xác định được LD50 trên chuột nhắt trắng của dung dịch EATWELLB theo đường uống. Kết quả nghiên cứu độc tính bán trường diễn cho thấy tình trạng chung, các chỉ số huyết học, chức năng gan, thận và hình thái vi thể gan, thận không có sự khác biệt so với lô chứng sinh học và so sánh với thời điểm trước khi dùng thuốc thử. Như vậy, dung dịch EATWELLB liều 1,8 mL/kg và 5,4 mL/kg uống trong 4 tuần liên tục không gây độc tính bán trường diễn trên động vật thực nghiệm.

Độc tính của thuốc lá nung nóng là chủ đề đang được quan tâm trong thời gian gần đây. Nghiên cứu này nhằm mục tiêu tổng hợp kết quả các thử nghiệm lâm sàng ngẫu nhiên có đối chứng đánh giá độc tính của thuốc lá nung nóng so với thuốc lá thông thường dựa trên các chỉ điểm sinh học phơi nhiễm. Mười bài báo gốc đã được tuyển chọn từ 187 bài báo theo tiêu chuẩn thuộc 3 cơ sở dữ liệu điện tử: PubMed, Sciencedirect và ProQuest từ 2010 - 2023 theo hướng dẫn PRISMA 2020. Kết quả cho thấy nồng độ của 14 chỉ điểm sinh học phơi nhiễm quan trọng (1-OH, 2-AN, 3-HMPMA, 3-HPMA, 4-ABP, CEMA, CoHb, HEMA, MHBMA, NNAL, NNN, S-PMA, TNeq, và O-Tol) đều thấp hơn có ý nghĩa thống kê ở những người hút thuốc lá nung nóng so với người hút thuốc lá thông thường; mức giảm cao nhất với TNeq (68,6%) và thấp nhất với CEMA (13,4%). Độc tính của thuốc lá nung nóng, đánh giá thông qua các chỉ điểm sinh học phơi nhiễm, giảm đáng kể so với thuốc lá thông thường. Tuy nhiên, vẫn cần có thêm các nghiên cứu độc lập, toàn diện hơn nữa về tính an toàn của thuốc lá nung nóng.
