Abstract. Space-based observations of solar-induced fluorescence (SIF) provide valuable insights into vegetation activity over time. The GOME-2A instrument, in particular, facilitates SIF retrievals with extensive global coverage and a record extending over 10 years. SIF retrievals, however, are sensitive to calibration issues, and instrument degradation complicates the construction of temporally consistent SIF records. This study introduces the improved Sun-Induced Fluorescence of Terrestrial Ecosystems Retrieval (SIFTER) v3 algorithm, designed to obtain a more accurate and reliable long-term SIF record from GOME-2A for the 2007–2017 period, building upon the previous SIFTER v2. The SIFTER v3 algorithm uses newly reprocessed level-1b Release 3 (R3) data, which provides a more homogenous record of the reflectances by eliminating spurious trends from changes in level 0 to level 1 processing. This improved consistency supports detailed analysis and correction of the reflectance degradation across the SIF retrieval window (734–758 nm). To address the reflectance degradation accurately, SIFTER v3 incorporates an advanced in-flight degradation correction that accounts for time, wavelength, and scan-angle dependencies throughout the entire record. Additionally, algorithm revisions have consistently reduced the retrieval residuals by around 10 % and reduced sensitivity to water vapor absorption by better capturing the atmospheric and instrumental effects. A revised latitude bias adjustment resolves unrealistic values of GOME-2A SIF over desert areas. The SIFTER v3 dataset demonstrates improved robustness and consistency, both spatially and temporally, throughout the 2007–2017 record, and aligns closely with independent GPP measurements from the global FluxSat and FLUXCOM-X products.

Abstract. Satellite observations of atmospheric methane are a powerful resource for helping to quantify methane emissions in service of climate action. The inverse methods needed to exploit these observations require a high level of scientific and technical expertise as well as access to large computational and data processing resources. The Integrated Methane Inversion (IMI) is an open-access cloud computing tool designed for researchers and non-expert users to obtain total sector-resolved methane emissions worldwide at up to 0.25°×0.3125° (≈25×25 km2) resolution by analytical inversion of TROPOMI satellite observations with closed-form error characterization. Here we describe IMI version 2.0 with vastly expanded capabilities relative to the original version. Major developments include: (i) a new blended TROPOMI+GOSAT dataset for higher data quality, (ii) incorporation of point source observations in state vector construction, (iii) order-of-magnitude speedup in Jacobian matrix construction, (iv) improved error characterization through use of super-observations, (v) improved methods for initial and boundary conditions, (vi) adaptive spatial resolution linked to observational information content, (vii) option to optimize tropospheric OH (main methane sink), (viii) global inversion capability, (ix) Kalman filter option for continuous monitoring of emissions, (x) updated default prior emission inventories, (xi) option for lognormal error probability density functions to characterize emissions, (xii) additional output visualization (sectoral emissions, temporal variability), and (xiii) containerization to facilitate download to local computing facilities and operation as part of the US GHG Center. A 2023 annual inversion with 28-day temporal resolution for the contiguous US (CONUS) is presented as demonstration of IMI 2.0 capabilities.
Attribution of riming and aggregation processes by application of the vertical distribution of particle shape (VDPS) and spectral retrieval techniques to cloud radar observations

Published: October 2024

Abstract. Advancing the understanding of mixed-phase cloud microphysical growth processes requires a thorough detection of the transition processes from pristine hydrometeor states toward aggregates, rimed particles and graupel. In this study, a versatile combination of techniques is applied to detect and characterize aggregated and strongly rimed hydrometeors even under harsh atmospheric conditions such as the presence of orographic gravity waves. The approach combines dual-frequency observations from vertical-stare Doppler cloud radars as well as measurements from a polarimetric scanning cloud radar. Core of the approach are profiles of the Vertical Distribution of Particle Shape (VDPS) method that serve as a proxy for the presence of columnar, isometric, or prolate cloud particles. At height levels within the VDPS-based shape profiles where isometric particles are identified, Doppler spectra and dual-wavelength vertical-stare cloud radar observations are used to discriminate the occurrence of aggregation or graupel formation. The underlying dataset was acquired in the framework of the 3-year field experiment, “Dynamic Aerosols Clouds and Precipitation Observation in the Pristine Environment in the Southern Ocean” (DACAPO-PESO) at the southern hemispheric midlatitude site of Punta Arenas, Chile (53° S, 71° W). The frequent presence of layers of supercooled liquid water and the permanent occurrence of orographic gravity waves motivate a strong interest to understand the formation of precipitation and the role of aggregation and riming at this site. Therefore, two case studies of both strong riming events and aggregation processes from the DACAPO-PESO campaign are presented to demonstrate the potential of combining the new VDPS retrieval with spectral methods, which analyze particle fall velocity and the coexistence of multiple particle types. We found that the identification of layers of supercooled liquid water is essential to pin down regions of riming in the observed cloud systems. In consequence, considering the general notion of the excess of liquid water in clouds over the southern hemisphere midlatitudes, our study serves as a preliminary investigation into the occurrence of riming and aggregation processes above Punta Arenas.

Published: October 2024

Abstract. Rewetting drained peatlands can reduce CO2 emissions but prevents traditional agriculture. Crop production under rewetted conditions may continue with flood-tolerant crops in paludiculture, but its effects on greenhouse gas (GHG) emissions compared to rewetting without further management are largely unknown This study was conducted between 2021 and 2022 on a fen peatland in central Denmark. At the study site, three harvest/fertilization management treatments were implemented on Reed Canary Grass (RCG) established in 2018. Measurements of CO2 and CH4 emissions were conducted biweekly using a transparent manual chamber connected to a gas analyzer and manipulating light intensities with four shrouding levels. Although this was a rather wet peatland (−8 cm mean annual WTD), the site was a CO2 source with a mean net ecosystem C balance (NECB) of 6.5 t C ha−1 yr−1 across treatments. Model simulation with the use of high temporal resolution water table depth (WTD) data was able to better capture ecosystem respiration (Reco) peaks compared to the use of mean annual WTD, which underestimated Reco. Data on pore water chemistry further improved statistical linear models of CO2 fluxes using soil temperature (Ts), WTD, ratio vegetation indices and PAR as explanatory variables. Significant differences in CO2 emissions and water chemistry parameters were found between studied blocks, with higher Reco corresponding to blocks with higher pore water nutrient concentrations. Methane emissions averaged 113 kg of CH4 ha−1 yr−1, equivalent to 11.3 % of the total carbon emission in CO2 equivalents. Because of large heterogeneity among the experimental blocks no significant treatment effect was found, however, the results indicate that biomass harvest reduces GHG emission from productive rewetted peatland areas in comparison with no management, whereas on less productive areas it is beneficial to leave the biomass unmanaged.
Analysis of ship emission effects on clouds over the southeastern Atlantic using geostationary satellite observations

Published: October 2024

Abstract. This study investigates the impact of ship emissions on clouds over a shipping corridor in the southeastern Atlantic. Using CLAAS-3, the 20-year (2004–2023) CLoud property dAtA set using SEVIRI, (the geostationary Spinning Enhanced Visible and InfraRed Imager), the diurnal, seasonal and long-term corridor effects on clouds are examined. Results show a significant impact of ship emissions on cloud microphysics, consistent with the Twomey effect: an increase in cloud droplet number concentration (Nd) and a decrease in effective radius (re). Additionally, cloud liquid water path (W) decreases, though changes in cloud fraction are more subtle. Seasonal and diurnal variations of the impact are also evident, influenced by regional conditions and by the cloud thinning during the day, respectively. The long-term analysis reveals a weakening of the shipping corridor effect on Nd and re presumably following the International Maritime Organization's 2020 stricter regulations on sulfur emissions, and broader regional changes in W and cloud fraction, associated with sea surface temperature variations. The methodology developed for this analysis benefits from the spatially constrained emissions in the shipping corridor, which enhance the detectability of corresponding effects on clouds. Focusing on a climatically important cloud regime, this study highlights the potential of geostationary satellite-based cloud observations for similar analyses.

Abstract. Annual forest maps at a high spatial resolution are necessary for forest management and conservation. Large uncertainties remain in existing forest maps because of different forest definitions, satellite datasets, in situ training datasets, and mapping algorithms. In this study, we generated annual maps of forest and evergreen forest at a 30 m resolution in the contiguous United States (CONUS) during 2015–2017 by integrating microwave data (Phased Array type L-band Synthetic Aperture Radar – PALSAR-2) and optical data (Landsat) using knowledge-based algorithms. The resultant PALSAR-2/Landsat-based forest maps (PL-Forest) were compared with five major forest datasets from the CONUS: (1) the Landsat tree canopy cover from the Global Forest Watch dataset (GFW-Forest), (2) the Landsat Vegetation Continuous Field dataset (Landsat VCF-Forest), (3) the National Land Cover Database 2016 (NLCD-Forest), (4) the Japan Aerospace Exploration Agency forest maps (JAXA-Forest), and (5) the Forest Inventory and Analysis (FIA) data from the U.S. Department of Agriculture (USDA) Forest Service (FIA-Forest). The forest structure data (tree canopy height and canopy coverage) derived from the lidar observations of the Geoscience Laser Altimetry System (GLAS) on board NASA's Ice, Cloud, and land Elevation Satellite (ICESat-1) were used to assess the five forest cover datasets derived from satellite images. Using the forest definition of the Food and Agricultural Organization (FAO) of the United Nations, more forest pixels from the PL-Forest maps meet the FAO's forest definition than the GFW-Forest, Landsat VCF-Forest, and JAXA-Forest datasets. Forest area estimates from PL-Forest were close to those from the FIA-Forest statistics, higher than GFW-Forest and NLCD-Forest, and lower than Landsat VCF-Forest, which highlights the potential of using both the PL-Forest and FIA-Forest datasets to support the FAO's Global Forest Resources Assessment. Furthermore, the PALSAR-2/Landsat-based annual evergreen forest maps (PL-Evergreen Forest) showed reasonable consistency with the NLCD product. The comparison of the most widely used forest datasets offered insights to employ appropriate products for relevant research and management activities across local to regional and national scales. The datasets generated in this study are available at https://doi.org/10.6084/m9.figshare.21270261 (Wang, 2024). The improved annual maps of forest and evergreen forest at 30 m over the CONUS can be used to support forest management, conservation, and resource assessments.

Authors: Khan Aman Ullah , Afsar Afifa , Sharif Salman , Ali Faridah Amir
Published: October 2024

Objective: This study aims to evaluate the short- and long-term outcomes—specifically in terms of pain, disability, and quality of life—between minimally invasive surgery (MIS) and open transforaminal lumbar interbody fusion (TLIF) for treating lumbar spondylolisthesis.
 
Study Design and Setting: A prospective cohort study was carried out at Liaquat National Hospital & Medical College, Karachi, and a teaching institution in South Asia. The study included patients with chronic back pain for over three months, unresponsive to medical treatment or accompanied by radicular symptoms, with MRI-confirmed grade I and II degenerative lumbar spondylolisthesis, lateral recess stenosis, and unilateral disc herniation. Patients with spinal metastasis, previous surgeries, inflammatory arthritis, or metabolic bone diseases were excluded.
 
Methodology: The outcomes of MIS-TLIF and open-TLIF were assessed using the Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and SF-36 quality of life scores at 1, 6, and 24 months postoperatively.
 
Results: Among 93 patients, 35 underwent open-TLIF and 58 received MIS-TLIF. MIS-TLIF resulted in significantly less blood loss and faster recovery. At four weeks, the MIS group had lower VAS and ODI scores, and higher SF-36 scores. Similar trends continued at six months, with improvements in ODI and SF-36. By 24 months, the MIS group maintained lower ODI scores, though VAS and SF-36 scores were comparable.
 
Conclusion: MIS-TLIF shows superior outcomes, especially in the early postoperative phase, with reduced morbidity and improved quality of life, making it a preferable option in resource-limited settings.

“Ik ben zoo diep gezakt door deze oorlog”
Authors: Jan Julia Zurné
Published: October 2024

During the German occupation of the Netherlands in the 1940s, crime rates for petty theft rose considerably. As a result of shortages, forced labor, unemployment and war damages, many citizens resorted to property crime. Those who were caught, were in majority sentenced within the Dutch judicial system, by Dutch magistrates, most of whom had no pro-German beliefs. This article explores how suspects, judges and probation officers referred to the occupation circumstances during the judicial process. All three types of actors saw how these circumstances could lead to theft. However, pre-existing notions of property and its defense were not radically questioned during the occupation. The (implicit) expectation was that the harmful consequences of the Second World War would be of a temporary nature.
Elementos de ética en una pieza de Deleuze
Authors: G. Soto Luís
Published: October 2024

El objetivo de este trabajo es ensayar una explicación e interpretación de la introducción “Répétition et différence” de Différence et répétition de Gilles Deleuze. Parte de la hipótesis de que es una pieza de un conjunto no desarrollado de filosofía moral. Esta pieza aborda cuatro elementos: conducta, ley, concepto y sujeto morales. El análisis detallado muestra que Deleuze esboza un programa de investigación de la acción moral que se inspira, como punto de partida, en el kantismo, y culmina en una doble propuesta: acercamiento de la acción moral a la acción estética y ética de la potencia. Los resultados apuntan a una génesis artística del sujeto moral actual.
Hacia una subjetividad sostenible: pensar la crisis ecológica desde la razón poética de María Zambrano
Authors: Valle Álvarez Jorge
Published: October 2024

La crisis ecológica supone la «Gran prueba» que debe afrontar la humanidad a lo largo de este siglo, pero las soluciones propuestas hasta el momento por los círculos económicos y políticos internacionales pasan por un capitalismo verde que no cuestiona las premisas filosóficas que sustentan el racionalismo moderno y que estarían en la base de la actual crisis: el antropocentrismo extremo, la desvalorización de la Naturaleza y el consecuente dominio del ser humano sobre el mundo natural. Así pues, en este artículo se propone ampliar la noción de sostenibilidad al campo de la filosofía, con el objetivo de alumbrar una nueva subjetividad sostenible que revalorice la Naturaleza y se sepa integrada y no radicalmente separada de ella. Con este fin, se pretende pensar la crisis ecológica desde la filosofía de María Zambrano, que frente a los excesos del racionalismo y el predominio de una razón soberbia, dominante y destructiva que aísla al ser humano y violenta e instrumentaliza el mundo, propone una razón poética que, por el contrario, es humilde, persigue la unión del ser humano con lo otro y se alza sobre el amor hacia la Naturaleza.
Lawrence Dewan y la forma como algo divino en las cosas
Authors: Serra Pérez Manuel Alejandro
Published: October 2024

Las principales disputas que han tenido lugar en el seno del tomismo contemporáneo han estado marcadas por un fuerte criticismo respecto a la escuela tomista dominicana. Las tesis más discutidas pueden sintetizarse en torno a la comprensión del esse y su énfasis en el conjunto de la filosofía del ser. El dominico canadiense Lawrence Dewan quiso contrarrestar este criticismo equilibrando este énfasis sobre el esse haciendo valer el papel de la forma en el pensamiento de Tomás de Aquino. La forma, que es algo divino en las cosas, no es sólo mera potencia receptiva, sino causa del esse y mediadora del acto creador del ente. En este artículo vamos a estudiar detenidamente las ideas principales del tomismo dewaniano a la luz de los aspectos más originales de la enseñanza del Aquinate, desde una perspectiva crítica.
Psique es extensa: una mirada deconstructiva de Descartes desde Jean-Luc Nancy
Authors: Sánchez Mayor Paula
Published: October 2024

A partir de una nota póstuma de Freud en la que otorga extensión a psique, este artículo reconstruye la lectura que Jean-Luc Nancy hace de la distinción cartesiana entre res cogitans y res extensa. La clave metodológica es la deconstrucción de una división que busca desesperadamente volver a la unidad como garante de la subjetividad moderna. De esta manera, a medida que se cuestiona la propuesta de Descartes, se va perfilando la apuesta de Nancy por un pensamiento del cuerpo que no obedece al principio de unidad y que asume el alma desde la figura del agujero.

El papel del compromiso académico en estudiantes de la mención de educación musical
Authors: Gustems Carnicer Josep , Navarro Calafell Mercè , Calderon Caterina
Published: October 2024

El compromiso académico es un concepto fundamental para explicar el rendimiento académico en universitarios, especialmente en estudios como el grado de maestro, que forma estudiantes para una profesión altamente vocacional. Asimismo, el actual sistema para formar maestros de educación musical mediante la mención plantea algunas ambivalencias respecto al compromiso de dichos estudiantes. Así, nuestro objetivo es comparar el compromiso académico y algunas variables facilitadoras y obstaculizadoras del mismo, en alumnado de esta mención con alumnado del resto de grados de maestro, con el objetivo de proponer acciones que redunden en un mayor aprovechamiento de estos estudios. Para ello se ha realizado un estudio exploratorio prospectivo de carácter transversal que combina metodología descriptiva y correlacional, con datos obtenidos a partir de distintos cuestionarios. La muestra estuvo formada por 610 alumnos de la UB. Los resultados más significativos que diferencian ambos grupos se encuentran, por una parte, en las variables facilitadoras del compromiso académico (estrategias de afrontamiento, y motivación académica), así como en las variables obstaculizadoras (estrés percibido y malestar psicológico). Con todo ello se plantean acciones para mejorar y complementar el plan de acción tutorial de los maestros de educación musical, y, por consiguiente, mejorar el compromiso académico de estos estudiantes.
Possibilities of music preferences measures in younger school age children
Authors: Peter Kusý , Vindišová Renáta
Published: October 2024

The musical-preference framework of a child at younger school age is gradually formed and shaped. The study outlined the possibilities of measuring musical taste at a younger school age and draws attention to the real specifics that this entails. We verified the newly created instrument - Musical Preference Questionnaire of Younger Pupils - MPQ-YP on 84 pupils (n=84) aged from 6 to 10 years (Mage=8.23). The 3-factor solution, which divides MPQ-YP into 3 categories of music genres - reflective and unconventional music; energetic and rhythmic music; optimistic and complex music, turned aout to be satisfactory. Psychometric properties are adequate, MPQ-YP seems to be sufficiently valid (construct and content validity) and reliable (measure of internal consistency and split-half reliability). Pilot descriptive results of younger schoolchildren's musical taste provide information about recognized musical genres and their preferences. The findings can be applied to the practice of music educators, music philetics and music therapists.

Published: October 2024

Las economías alternativas se han convertido progresivamente en objeto de interés para la comunidad científica, tanto por ser un tema multidisciplinario que abarca una gran cantidad de áreas de estudio, principalmente las ciencias económicas y geografía, como por la posibilidad de acercarse y estructurar otras formas posibles de conceptualizar el desarrollo económico y social. A través de una búsqueda bibliográfica realizada en la Web Of Science, una de las principales plataformas de investigación, se desarrolló un análisis bibliométrico establecido en un período de tiempo comprendido entre 1928 y 2023, obteniendo como búsqueda final 3.723 resultados sobre documentos científicos pertenecientes al campo de estudio de las economías alternativas. Este análisis permitió establecer los autores, instituciones, países, publicaciones y revistas más influyentes y productivas en este tema de las economías alternativas; asimismo, la utilización del software VOSviewer permitió el desarrollo de un mapeo científico donde se analiza la co-ocurrencia de palabras claves utilizadas por los autores. Éstas fueron agrupadas en clústeres de análisis, estableciendo así los temas con mayor producción e importancia dentro del ámbito de las economías alternativas, entre los cuales se denota la importancia que han cobrado dentro de la producción científica términos vinculados a la economía colaborativa y economía circular, entre otras, tan mediáticos actualmente. En definitiva, con el fin de aportar argumentos al debate científico sobre la relevancia de las economías alternativas se plasman tanto las conclusiones como las limitaciones que se han encontrado en la realización de este análisis bibliométrico y las posibles líneas futuras que pueden desarrollarse sobre la cuestión.

Published: October 2024

Study purpose. In physical education and sports lessons, correctly dosing effort is essential for optimising physical performance and adapting effort parameters, including breaks, in line with physiological principles. The study hypothesises that using smart-watches and mobile apps to monitor effort in middle school physical education lessons will reveal significant differences in effort and heart rate between overweight and average BMI students. Modern technology is expected to enhance understanding of students' physical exertion, facilitating adjustments to programs based on health status and fitness level.
Material and method. The study involved 45 students (average age 13.5 years) using 15 Xiaomi 8 smart-watches, phones, Wi-Fi, the Mi Fit app, and other devices to analyse body composition. Data on heart rate and BMI were collected during lessons, which followed the same theme and effort dosage. The Mi Fit app provided detailed aerobic and anaerobic exertion analyses. Parental consent was obtained, and data collection was done under routine lesson conditions. The technology aimed to improve performance and customise programs, offering a personalised approach to physical education. Real-time data transfer enabled accurate analysis of physical effort, promoting healthier lifestyles and better lesson adaptation by teachers.
Results. A significant interaction between heart rate and BMI steps (p < 0.01) shows different cardiovascular adaptations to exercise based on BMI. MANOVA confirmed the significant impact of these variables on heart rate, and post hoc comparisons showed differences between weight categories, except between overweight and extremely obese groups. These results highlight the need to tailor physical education programs to BMI categories to optimise cardiovascular health and performance.
Conclusion. Results suggest that monitoring the effort curve using modern technologies, such as smart-watches and mobile apps, provides valuable information for adjusting and optimising physical education lessons, especially for overweight and obese students.

Published: October 2024

Purwakarta has 62 tourist destinations in 2023, one of the interesting places to visit is Pelangi Forest, Mount Cupu, Purwakarta. This destination has been established since 2017 on an area of 5 (five) hectares and is still being developed. It is called Pelangi Forest which means Rainbow Forest because it has a unique theme, decorating the forest with lots of colorful ornaments like a Pelangi. However, the level of tourist visits is still very low, it is known that there were only 2,582 tourists per year in 2020. This research aims to analyze the extent of the natural tourism potential of Pelangi Forest. The method used is quantitative descriptive, where data collection is carried out through distributing questionnaires to 30 tourists. The collected data was then analyzed using the Analysis of Operation Area-Natural Tourism Objects and Attractions (Analisis Daerah Operasi Objek dan Daya Tarik Wisata Alam (ADO-ODTWA)) criteria assessment by the Directorate General of PHKA by providing an assessment of each specified indicator. The results obtained were that the Pelangi Forest was suitable for development as a natural tourism objects and attractions (73.92%>66.67%). It is hoped that this research can become a reference and alternative strategy for managing the Pelangi Forest in developing its tourist attraction to be more optimal so that it can increase the number of tourists in the future, as well as being a source of information for other parties who need it through published journals

Indonesia's abundant natural resources have spurred interest in exploring certain plants believed to possess aphrodisiac properties that can enhance male libido and reproductive health. This research endeavor is designed to delve into the extraction of compounds from various plant species, followed by a comprehensive analysis of their chemical constituents. Subsequently, aphrodisiac activity assessments are conducted on male rats, focusing on key parameters such as mating frequency, climbing behavior, and coital activities. Additionally, this investigation encompasses the determination of the percentage of relative testicular weight in relation to body weight and histopathological examination of testicular organs. The findings emanating from the extracts of Piper retrofractum (PRE), Solanum melongena fruit (EE), Ocimum basilicum leaves (OBLE), Watermelon albedo (WAE), and Zingiber officinale Var Rubrum rhizoma (ZRE) reveal the presence of alkaloids, flavonoids, and saponins. Notably, EE, administered at a dosage of 30mg, yields the most prominent aphrodisiac effects in the test subjects, as evidenced by heightened mating frequency, climbing activity, and coital behaviors. Furthermore, the relative testicular weight following treatment with 30mg of PRE closely resembles the impact observed with sildenafil at a dosage of 10 mg/kgbw.

Published: October 2024

Aziridines are three-membered ring heterocycles that include nitrogen and are well-known for their employment as reactive intermediates in the production of chiral amino alcohols, azomethine ylides, and derivatives of amino acids. The current study was based on the synthesis, identification, docking study and evaluation of antioxidant potential of novel derivatives of aziridine. The novel derivatives of aziridine were synthesized and identified the synthesized aziridine derivatives based on physicochemical properties i.e., boiling point, Rf value, FTIR, NMR and Mass spectroscopy and Docking study. With a binding energy of -6 to -9 Kcal/mol, every chemical has demonstrated effective docking inside the antioxidant activity protein's active region. We contrasted the anticipated docking data with proteins known to have antioxidant action. In results, the % yield was observed as 48.24, 49.72, 48.39 and 49.12 in compound A4, A7, A10 and A12, respectively. Highest Rf values were observed in A3, A5, A7 and A 11 as 0.74, 0.76, 0.77, and 0.74, respectively. A4 showed boiling point 210ºC. Based on docking study, all the compounds were found active, however compound A1, and A4 were demonstrated the highest binding energy (affinity). Derivatives of aziridine A2, A3, A5, A6, A8, A9, A10, A11, A12 were found also found active with some moderate binding affinity. It concluded that 12 novel derivatives of aziridine were synthesized and characterized with their physicochemical properties and spectral analysis (NMR, Mass, FTIR). In docking study, compounds A1 and A4 demonstrated the highest binding affinity among all 12 aziridine derivatives. Thus, active aziridine derivatives might be used in the evaluation of the biological potential. It suggests to perform the acute oral toxicity of the synthesized aziridine derivatives and antioxidant activity.

The synthesis of nanoparticles has garnered significant attention due to their wide range of applications and exceptional properties and due to the toxicity of chemicals used in conventional methods, a matter that imposes considerable risks to human health and the environment. As a response to this issue, eco-friendly alternatives known as green synthesis techniques have emerged such as selenium nanoparticles (SeNPs) that hold great promise in biomedical applications. Green synthesis which utilizes plants, microorganisms, and waste materials offers distinct advantages including precise control over the size and shape of the nanoparticles. By carefully optimizing various parameters, this approach enables the production of uniform and stable SeNPs. Importantly, green synthesis eliminates the need for hazardous chemicals, thereby reducing environmental pollution and potential harm to human health. The process typically involves heating a mixture of sodium selenite, plant extracts or culturing microorganisms with selenium precursors to facilitate the formation of SeNPs. Various techniques such as UV-visible (UV-Vis) spectrophotometry, transmission electron microscopy (TEM), and scanning electron microscopy (SEM) are used to characterize these SeNPs. Of note, bacterial-mediated synthesis of SeNPs, achieved through intracellular or extracellular processes, effectively reduces selenium ions into SeNPs. To add, the type of the plant extract plays a crucial role andit was found that different extracts yield SeNPs with distinct properties. Moreover, a large body of evidence revealed that the plant extracts that are rich in reducing and stabilizing agents such as flavonoids and alkaloids can reduce selenium ions into SeNPsresulting in a biocompatible surface. Accordingly, green synthesis methods that employ plant extracts and bacteria hold great promise and sustainability, as they allow a control over the shapes of nanoparticles and the generation of unique properties tailored for biomedical applications. These approaches are not only cost-effective but also environmentallyfriendly, consistently producing nanoparticles with narrow size distributions. Despite certain limitations of this approach, the potential of green synthesis in nanoparticle synthesis is undeniable.
