Efecto de biocontroladores aislados en fincas productoras de cebolla sobre la pudrición blanca (Sclerotium cepivorum)
Authors: Granados María del Milagro , Wang Amy
Published: May 2024

Para evaluar el efecto de Trichoderma spp., Clonostachys spp. y Beauveria bassiana sobre la incidencia de la pudrición blanca de la cebolla (Sclerotium cepivorum), se realizó un experimento de invernadero. Los aislamientos fueron recuperados de esclerocios colectados en fincas productoras de cebolla de la zona alta de Cartago, Costa Rica. Plántulas de cebolla fueron sembradas en suelo inoculado con el patógeno (0,06 esclerocios.g-1 de suelo) y se les realizó 3 aplicaciones con los biocontroladores, individualmente o en mezcla. La primera aplicación se realizó a la siembra (230 g.maceta-1 de 3,5 kg). A las 4 y 8 semanas se realizó la segunda y tercera aplicación (500 ml de sustrato.maceta-1, con 5x106 ufc.ml-1). A las 18 semanas, se evaluó la incidencia de la enfermedad. Los resultados indicaron una diferencia (p=0,0117) entre el testigo (sin biocontroladores) y los demás tratamientos. La incidencia de pudrición blanca mostró el siguiente patrón: testigo 46%; Beauveria bassiana 17%; Clonostachys spp. 8,3% y 7,1%, respectivamente; Trichoderma spp. O%. El análisis de varianza no mostró diferencias (p=0,5883) entre las medias para la longitud foliar. Estos resultados indican que todos los biocontroladores evaluados ejercen algún grado de control sobre la enfermedad, en particular Trichoderma spp.
Crisis Management in Russia-Turkey Relations (Based on the Example of the Syrian Crisis 2010–2021)
Authors:   University of Tehran, Sanaei Mehdi , Hooshyar Kamran ,   University of Tehran
Published: May 2024

Introduction. In recent years, issues related to the Syrian crisis, including the shooting down of a Turkish fighter jet by Syria on June 22, 2012, the forced landing of a Syrian passenger plane in Ankara on October 10, 2012, and the shooting down of a Russian Su-24 jet by Turkey on November 24, 2015, have become a serious challenge for Russia and Turkey. Moscow and Ankara took completely opposite positions and moved to direct confrontation, but gradually these two actors managed to avoid an escalation of tensions by synchronizing their positions. Methods and materials. The main research question is: how did Russia and Turkey deal with competition and tension in their relations, which pushed them to cooperate? In response to this hypothesis, it is assumed that along with all the constant and variable factors, including geopolitics, economic cooperation, and opposition to Western unilateralism, this cooperation between the two leaders, Putin and Erdogan, has led to a kind of crisis management and a reduction in tensions between the two countries. This has created a delicate balance of competition and cooperation between the two countries. As a theoretical approach, this study examines international crisis management and its applied interpretation in political research on conflict management (conflict situations) and the role of personality and the “rational actor” model in decision-making theory. The research method in this article is a case study; several crisis cases were analyzed, and the main influencing factors in controlling the relationship between the two countries were identified. Results. The main conclusion of the study is that in crisis management, the role of the individual in the image of an intelligent leader in the implementation of policies with full control over subordinate organizations played a significant role. Authors’ contribution. Mehdi Sanaei is responsible for the concept of the article, the development of its theoretical part, the identification and discussion of controversial issues about crisis and conflict management, and the assessment of information sources. Kamran Hooshyar studied the literature and expert opinions, tested the hypothesis about the large role of the heads of state of Russia and Turkey as political leaders in cooperation, and analyzed the economic and political aspects of cooperation between the two states.
ESCRITAS FRAGMENTÁRIAS NA LITERATURA LATINO-AMERICANA
Authors: Olmos Ana Cecilia
Published: May 2024

RESUMO Este artigo propõe uma indagação sobre as escritas fragmentárias frequentadas por autores da América Latina nos séculos XX e XXI. Trata-se de práticas de escrita que se configuram no trânsito entre a anotação, a crônica, o diário e o ensaio, num movimento discursivo que tende a apagar as distinções entre literatura e vida. Ainda que a fragmentação seja reconhecível como estratégia discursiva crítica de uma modernidade literária que, como diz Jacques Rancière, fez da corrosão do próprio conceito de literatura seu fundamento, cabe colocar a pergunta acerca das inflexões que ela assume nos dias de hoje, em que a literatura parece abandonar seus foros específicos e, em um movimento de identificação com a experiência e o mundo, colocar em xeque a autonomia estética. Em diálogo com uma reflexão teórica sobre as escritas fragmentárias, que contempla os aportes de Lacoue-Labarthe, Nancy, Barthes, Blanchot e Rancière, o artigo traça um percurso por escritas fragmentárias da América Latina que convoca os nomes de Macedonio Fernández, Ricardo Piglia, Salvador Elizondo, Mario Levrero, dentre outros autores.
NUMERICAL STUDY OF RAYLEIGH-BÉNARD CONVECTION IN THIN CYLINDRICAL LIQUID LAYERS
Authors: Vinokurov V. A. , Vinokurov V. V. , Marchuk I. V. , Kabov Oleg A.
Published: May 2024

The evolution of the flow structure of thermal gravity-capillary convection in thin cylindrical water layers with a free surface, heated from below, was numerically studied. The layer diameter ranges from 10 mm to 40 mm, and the height ranges from 0.1 mm to 5 mm. The influence of the layer height and temperature difference on heat transfer was investigated, and the boundaries for the transition to nonstationary flow regimes were determined. The relative contributions of buoyancy and thermocapillary effects were examined, and analytical dependencies for heat dissipation from the free surface as a function of temperature difference and layer height were constructed. The dimensions of the ordered Rayleigh-Bénard convective cells were determined to be approximately 0.42 mm for a diameter of 40 mm and a layer height of 400 μm, which is comparable to the size of monolayer levitating microdroplets above an evaporating liquid layer in the atmosphere.
MICROSTRUCTURAL FEATURES DURING FAILURE OF NEPE/AP/AL PROPELLANT UNDER UNIAXIAL COMPRESSIVE LOADING
Authors: Jain Preetesh , Ranjan Rajeev , Murthy H.
Published: May 2024

The present study investigates the failure mechanism of nitrate ester plasticized polyester (NEPE) propellant subjected to uniaxial compression using microstructural analysis. The tests were conducted at room temperature and at 1, 50, and 10 × 102 mm/min displacement rates. The specimens were loaded up to different displacements corresponding to different compression stages and then interrupted/stopped, followed by unloading. Subsequently, micrographs of the surface and cross section of the specimen were studied using a scanning electron microscope (SEM) and energy dispersion spectroscopy (EDS) to understand the microstructural changes associated with corresponding deformation. The three stages of nonlinear behavior/damage beyond the initial linear region were chosen based on the true stress-strain response of the propellant. It was observed that the damage evolution is accelerated with an increase in displacement rate since the matrix has less time to rearrange itself. In stage 1 (yielding), debonding (indicating damage initiation) was observed at 50 mm/min, and debonding accompanied by cavities was observed at 10 × 102 mm/min, while there was no observable debonding at 1 mm/min. At the other end, in stage 3 (strain-hardening), while only cavities and debonding were observed at 1 mm/min and 50 mm/min, ammonium perchlorate (AP) particle breaking and void formation were observed at 10 × 102 mm/min, thus indicating more severe damage. EDS mapping was used to identify AP and aluminum particles. SEM observations indicate that AP particles exhibited debonding while aluminum particles remained firmly attached, across all stages.

Published: May 2024

This paper presents the variations in subsoil conditions of the Bangkok Metropolitan Area of Thailand. The study was initiated by measuring ambient noise with a seismometer. A total of twenty sites was investigated by microtremor measurements. The typical subsoils of Bangkok were presented on the basis of site investigation reports. Furthermore, inversion analysis was conducted to determine subsoil properties in Bangkok. Geotechnical parameters for seismic analyses, such as soil layer thickness, undrained shear strength (su), unit weight, time-averaged shear wave velocities at 30 m (Vs30), 100 m (Vs100), and 500 m (Vs500), and engineering bedrock surface depth were reported. Results shows that clay layer thickness varies from 17 - 25 m with the su of approximately 10 - 60 kPa and unit weight of approximately 15 - 17.5 kN/m3. The results also show that Vs30, Vs100, and Vs500 fall in the ranges of 100 - 225, 175 - 300, and 325 - 450 m/s, respectively. Engineering bedrock with the Vs of 760 m/s is found at 375 - 625 m below the ground. This result also indicates that a thick sediment is generally found in the Bangkok Metropolitan Area. In general, the results of this work could be used for civil engineering practice, especially seismic design and analysis in the studied area.

Abstract
Franz Beckenbauer und das Schweigen des Künstlers
Authors: Bredekamp Horst
Published: May 2024

Die deutsche Mannschaft war drückend überlegen, aber es fehlten die Tore; ein schmeichelhafter Elfmeter, den Andy Brehme gegen alle Absprachen ausführte, weil den Kapitän und eigentlichen Schützen Lothar Matthäus in einem psychosomatischen Übersprung der Schuh drückte, brachte den erlösenden 1:0-Sieg über Argentinien im Finale der Fußball-Weltmeisterschaft am Abend des 8.Juli 1990 in Rom. Nach dem Schlusspfiff wogte der Pulk der Mannschaft als ein zuckendes Bündel von Gesten der Verbrüderung, des rasenden Triumphes und der Fassungslosigkeit über die Hälfte des Platzes zur deutschen Stadiontribüne, um dort im Sommer der Wiedervereinigung von einem schwarz-rot-goldenen Fahnenmeer jubelnder Zuschauer aufgesogen zu werden. Auch die Italiener, die zuvor gegen Maradonas Argentinien in Neapel ausgeschieden waren, hielten mehrheitlich zu den tedeschi.
Lob des Nichtstuns
Authors: Capek Karel
Published: May 2024

Ich möchte nicht irgendwo nach draußen gehen, denn gehen ist nicht mehr nichts tun; auch nicht lesen, auch nicht schlafen, denn weder dies noch jenes ist Nichtstun; auch nicht sich unterhalten oder sich ausruhen, denn das Nichtstun ist weder Sichausruhen noch Vergnügen. Das Nichtstun, das reine, vollkommene Nichtstun ist weder Kurzweiligkeit noch Langeweile. Das Nichtstun, das ist etwas Negatives; es ist die Abwesenheit von allem, was den Menschen beschäftigt, unterhält, ablenkt, interessiert, beansprucht, quält, freut, was er schätzt, was ihn herausfordert, vergnügt, langweilt, verzaubert, nervt, vereinnahmt oder verunreinigt. Es ist nichts, Verneinung, Zwecklosigkeit, Ziellosigkeit, ich weiß nicht, wie ich es noch sagen soll; kurz, etwas Vollkommenes und Wertvolles.
Wie die Postmoderne den Sozialismus besiegte

Die Fragen von «Adaption» und «Integration» kommen jedes Mal auf, wenn wir im Westen über Osteuropa sprechen. Genauer gesagt, über die Menschen, die in Osteuropa aufgewachsen sind. Wir fragen uns, inwieweit wir, die Osteuropäer, überhaupt Teil der europäischen Kultur sind. Jedenfalls erlitt ich, als ich zum ersten Mal ins Ausland reiste, nicht nur einen Kulturschock. Ich hatte eine Halluzination. Als ich aus der Leningrader Region kommend die finnische Grenze überquerte, sah ich, wie der Himmel im kapitalistischen Finnland hellblau aufleuchtete und das Gras seine Farbe von grau nach smaragdgrün änderte. Als ich mich später mit meinen Landsleuten über dieses Phänomen unterhielt, fand ich heraus, dass auch viele andere eine solche Halluzination erfahren hatten.

Approaches to Determining the Law of a Constituent Entity of the Russian Federation That Establishes Regional Tax Exemptions: The Experience of the Siberian Federal District
Authors: Khabdaev Aleksandr
Published: May 2024

The article notes that when the state authorities of the constituent entities of the Russian Federation exercise the powers to establish tax exemptions for regional taxes they are significantly limited by the provisions of federal legislation. The Tax Code of the Russian Federation establishes an exhaustive list of powers of regional authorities, but in terms of exemptions for regional taxes, it provides the constituent entities of the Russian Federation with the opportunity to determine independently the list of taxpayers and the amount of exemptions. At the same time, the form of the legal act is predetermined (the law of the subject of the Russian Federation), but the region has a choice of their number and subject of legal regulation. A comparative analysis showed that the constituent entities of the Russian Federation included in the Siberian Federal District use different approaches. In most of them, exemptions are established in several laws, each of which is dedicated to a separate regional tax. At the same time, there is an example of the establishment of tax exemptions by a single tax law. There are also examples of the introduction of additional tax exemptions for certain categories of taxpayers by independent regional laws, along with general tax exemptions established by the law on a specific tax. The author concludes that all indicated approaches do not contradict federal tax legislation.
It is noted that earlier in the regions there was a practice of regulating the procedure for making a decision on the introduction of tax exemptions by separate laws, but today this issue is being resolved by assessing their effectiveness and is regulated at the by-law level, which does not contradict the procedure for establishing and introducing tax exemptions.
Finally, it was concluded that a meaningful analysis of various approaches to establishing tax exemptions in the regions included in the Siberian Federal District did not reveal differences in the issue of internal systematization of tax exemptions, since they are set separately for each tax. However, in some regions there has been a tendency to systematize tax exemptions by categories of taxpayers. The use of various approaches is due to the goals of regional legal regulation and does not exclude further systematization of tax exemptions.
Approaches to the Effectiveness Assessment of Territorial Development from the Perspective of ESG-Principles
Authors: Sapozhnikov Alexander
Published: May 2024

Municipal territorial management is a classic mechanism of territorial administration, which involves the nomenclature operation of existing engineering and social infrastructure facilities located in a certain area of the municipality. Such a mechanism for managing territories is characterized by relatively low economic returns, due to the limited resources of the administrative apparatus of the municipality and the complexity of the proprietary property structure of the administered territories. These factors together form a situation where municipal authorities provide the process of managing territories with standard measures to maintain urban infrastructure in a functional state, with the priority of stabilizing the socio-economic situation in the territory of the municipality. To optimize the territorial management system at the present stage of development of management mechanisms of territorial administration, comprehensive systems for assessing the development of municipalities are used, a striking example is the urban environment quality index. However, this indicator can also be used to assess the predisposition of municipal territories for the implementation of development projects based on taking into account energy stability, the natural environment and the market situation within a particular city. The article describes a conceptual model for supplementing and improving the existing system for assessing the urban environment in the form of the urban environment quality index, developed by the Ministry of Construction of the Russian Federation. The purpose of the proposed mechanism for modernizing the system is to determine indicators of the stability and potential of the energy system of the municipalities under consideration, as well as their integration into the system for assessing the quality index of the urban environment from the perspective of development design, as well as assessing the development potential of the territory based on ESG-principles.
The End-to-End Testing of the Material Accounting and Analytical Support System of Organizations
Authors: Kukartseva Daria , Ivakina Iraida , Pechenkina Alena
Published: May 2024

Relevance. Economic activity of organizations in modern market conditions leads to the need of constant search of ways to improve the accounting of materials and control over their movement, as well as the management of expenditure of these resources for production, which is one of the most important sources of growth in the efficiency of production activities, the growth of competitiveness of the economic entity and its financial stability.
Novelty. Many authors (S. Kukushkin, V. Pozdnyakov, O. Pshenichnikova, E. Sitikova, L. Bobrovskaya, N. Kondrakov, O. Shvyreva, N. Kazakova and others) have considered the issues of planning, analysis, accounting and control within the system of accounting and analytical support of materials, but each of them chose a specific block for research, because of which there is no holistic understanding of the process of providing the organization with the necessary working capital. The end-to-end testing is not a well-studied tool of internal control at all.
The methods used in the study of the issue of development and implementation of accounting and analytical support of materials in manufacturing enterprises are analysis, modelling, deduction, concretization, description, and interview with various experts in the field of accounting, external audit and internal control.
As a result of the study, a flowchart of the business process related to the acquisition, storage and disposal of inventories was developed, and the end-to-end testing was implemented as a tool to control the movement and use of such working capital in economic entities of the production organizations. These recommendations will help to make management decisions in a relevant and qualitative manner.
Narrativas de crisis migratoria: odio y securitización en la frontera EUA-México
Authors:   Universidad Autónoma de Baja California-México, Méndez Fierros Hugo , Pacheco Rosas Juan Carlos ,   Universidad Autónoma de Baja California-México
Published: May 2024

La frontera entre Estados Unidos de América (EUA) y México compone mucho más que una delimitación territorial, se ha transformado en una poderosa metáfora de división y a la vez de conjunción, socioeconómica y cultural, alimentada por narrativas que conforman no solo la percepción pública de la migración, sino también de las políticas dirigidas a su gestión. El presente artículo explora el entramado discursivo que rodea la fenomenología de la migración irregular y su percepción como amenaza en algunos sectores políticos y de la sociedad estadounidense. Se revisan las dinámicas discursivas que estigmatizan a las personas migrantes como una “invasión” simbólica, buscando entender cómo dichas narrativas impactan la construcción social de la securitización fronteriza. En esta zona de interacciones y conflictos, las personas migrantes en condición irregular se enfrentan no solo a barreras físicas, sino también a un laberinto de producciones simbólicas que les posicionan dentro de imaginarios colectivos como una “crisis amenazante” que debe ser contenida y repelida.

The Relationship Between Economic Development, Banking Sector Performance and Financial Globalization: Evidence from OECD Countries
Authors: Sümerli Sarıgül Sevgi , Avcı Pınar
Published: May 2024

The aim of this study is to examine the relationship between the economic development of the 11 OECD countries selected in the period 1990-2018, banking sector performance and financial globalization by integrating investments and trade openness as explanatory variables. The cointegration between variables is investigated by Pedroni, Kao and Westerlund tests and the long-term coefficients are determined by Driscoll-Kraay standard errors forecasters. Finally, the causality relationship between variables is tested in the Dumitrescu-Hurlin panel bootstrap approach. Empirical findings indicate the existence of cointegration between variables. The banking sector performance, financial globalization and investments have a statistically significant positive effect on economic development, while the trade openness has a meaninglessly positive effect. They also indicate a two-way causality between the economic development and banking sector performance and investments, and a one-way causality running from trade openness to economic development. Therefore, the findings make political recommendations for both policymakers and future studies.

El artículo identifica las vulneraciones y los riesgos específicos que existen para mujeres, niños, niñas y jóvenes que habitan en contextos de conflicto urbano en Medellín y que se involucran con las actividades realizadas por organizaciones de base artístico-culturales. El análisis emplea revisión documental, entrevistas semiestructuradas, recorridos territoriales y observación participante en actividades realizadas por los colectivos. Aunque el conflicto urbano de Medellín ha sido ampliamente estudiado en la bibliografía académica de diferentes disciplinas, este artículo aporta elementos de análisis, desde la perspectiva de la protección civil no armada y la autoprotección comunitaria, sobre las vulneraciones y riesgos diferenciales a los que se exponen las personas que hacen parte o se involucran con organizaciones artístico-culturales de base. Se concluye que los grupos poblacionales en los que se enfoca la investigación no solo están expuestos a afectaciones diferenciales relacionadas con su condición de género o edad, sino también el contexto cotidiano en el que viven; además, aunque las organizaciones brindan espacios seguros para los civiles que viven en sus zonas de incidencia, sienten que las entidades estatales los han dejado solos.

Authors: Shiyan O.A. , Iakshina A.N. , Oskina Y.O.
Published: May 2024

In the article play is considered as a space for the development of creative (dialectical) thinking in preschool age. The aim of the study is to analyze the relationship between the success of children in solving creative (dialectical) tasks and initiative in spontaneous play. The study involved 57 preschoolers from 2 preschool groups, contrasting in the quality of the educational environment. A qualitative and quantitative analysis of the initiative in play was carried out using an observation tool developed on the basis of the methodology of E.O. Smirnova. A total of 14 videos of a joint play were analyzed. “What can be simultaneously at the same time”, “Dialectical stories”, “Three stories” were used to measure the level of creative (dialectical) thinking. Qualitative analysis made it possible to distinguish two types of initiative actions – maintaining and changing the course of play. The study revealed the correlation between creative thinking in children’s narratives and play-changing initiative. The study points to the value of play as an activity where the child can not only solve, but also set tasks.

Hypcalcemia is a rare cause of dilated cardiomyopathy, but should be suspected in the presence of an obvious long QT interval on the surface ECG; we report a case of 46 years-old-woman, with surgical history of thyroidectomy 6 years ago, admited in our cardiology departement for mangement of congestive heart failure secondary to dilated cardiomyopathy,  her surface  ECG showed sinus rhythm with  long QT interval, his blood tests showed severe hypocalcemia and  low serum concentration of parathyroid hormone (PTH), cardiac magnetic resonance imaging was in favor of non ischemic dilated cardiomyopathy.
Concomitant with conventionel heart failure treatement, our patient had received parenteral   calcium supplementation, vitamin D, levothyrox; after four weeks, heart failure symptomes  were relieved, the intervalle QT has shortened, but persistant severe left ventricular systolic dysfuction. 
Hypoparathyroidism is frequent after thyroidectomy, and could be responsible of severe hypocalcemia which in turn may induce irreversible dilated cardiomyopathy.

Racism has been a prevalent issue ever since the concept of race was known to mankind, due to this fact, a lot of kinds of racism emerged in society.This study explained the experiences of Callum and his family through the levels of racism as well as how they responded towards the racism itself in the novel Noughts + Crosses by Malorie Blackman. This study itself is a literary criticism focusing on sociological approaches by employing two theories, one by Camarra Phylis Jones named levels of racism (2000) and the second one is multimotive theory by Richman & Leary (2009). Based on the analysis of this study, the first level of Jones’ theory seems to be the most prominent out of the three which is the institutional racism, the characters in this novel were restricted or has limited access to quite a lot of government infrastructure, silenced voice, as well as small quantity of representative in power. While the personally-mediated racism manifested itself through the suspicion of minorities; especially Callum, lack of respect from the Crosses, devaluation of minorities’ capabilities, scapegoating, and dehumanization through hate crime and police brutality. In internalized racism there is also evidence of whiteness as in Lynette’s case where she believes herself to be black as well as self-devaluation by the characters themselves for example Ryan who used the slur word to his own race.  Callum and his family responded with various types of response, such as Jude who is leaning towards being more aggressive after the experience of racism while Callum at least try to regain relational value within the society with relationship-promoting response as well as trying to exclude or withdraw himself from the society with avoidance or withdrawal response.

Zebrafish are becoming a valid model for investigating obesity and its associated disorders within a scientific context. The comprehension of the metabolic parameters linked to heightened body mass, adiposity, and energy expenditure stands as an indispensable endeavor in unraveling metabolic requisites among vertebrates. In this particular investigation, a cohort of 48 zebrafish specimens was scrutinized to determine the impact of physical exercise when subjected to a hypercaloric diet. The subjects were categorized into four distinct groups, each group respectively assigned to maintenance diets (GM, n=12, and GMex, n=12) or hypercaloric diets (GH, n=12, and GHex, n=12), with or without concurrent engagement in physical exercise. Applying a one-way ANOVA, with a significance level of P ≤ 0.05, the results revealed noteworthy findings. Among the GMex group, regarding body mass, a statistically significant variance was observed during the initial week (0.30g ± 0.10). This disparity demonstrated a reduction of 30.83% in the subsequent week, 33.59% in the fourth week, and 40.01% in the sixth week. Similarly, within the GH group, the analysis of variance unveiled significant deviations in body mass (in grams) from the inception of the study (0.32g ± 0.07), in comparison to measurements from the sixth through the thirteenth weeks. The GHex group exhibited significant differences in body mass between the first week (0.27g ± 0.08) and the subsequent weeks, extending until the thirteenth week. Furthermore, discernible variations in the length (in centimeters) of the zebrafish specimens were recorded, with statistical significance observed from the ninth (3.29cm ± 0.33) to the thirteenth weeks (3.61cm ± 0.33). The implementation of a hypercaloric diet yielded an augmentation in body mass. Additionally, the combination of this dietary regimen with physical exercise further contributed to an augmentation in the length of the zebrafish specimens. Collectively, the proposed model exhibited the capability to induce discernible metabolic effects, thereby enhancing our understanding of the intricate interplay between diet, exercise, and metabolic dynamics.
A Novel Iterative Hyperparameter Optimization Method for Enhanced Diabetic Retinopathy Screening
Authors: Karadayi Ataş Pinar
Published: May 2024

A major contributor to blindness in people of working age worldwide is diabetic retinopathy (DR), which is mostly caused by vascular damage brought on by high blood sugar in those who have diabetes mellitus. Since early detection greatly reduces the risk of vision loss, it is essential for the effective management of DR. This work presents a novel method that uses artificial intelligence (AI) to improve fundus image analysis for early diagnosis of diabetes mellitus (DR). Understanding how important high-quality images are to precise diagnosis, our approach starts with a sophisticated preprocessing stage. This stage focuses on improving the pictures by removing erroneous dark patches and other distortions, readying the dataset for additional examination. After preprocessing, we utilize an innovative hybrid hyperparameter optimization model that creatively combines the best features of grid and random search techniques. In order to identify early indicators of DR, such as microaneurysms and vessel changes, this model seeks to optimize the parameters of machine learning algorithms. Through a methodical analysis of the preprocessed fundus images, our model more effectively and accurately detects patterns suggestive of early-stage DR. The results of this study not only show that using AI in conjunction with careful preprocessing and hyperparameter optimization is effective in diagnosing DR, but they also open up new avenues for future investigation into the use of AI in early disease detection. In the end, this study makes a substantial contribution to the field of medical imaging and presents a viable treatment option for preventing vision loss in diabetic patients through early diagnostic intervention.

In agriculture, the use of fertilizers has increased due to the high demand for food by humanity, causing negative impacts because of high production costs and soil contamination. We evaluated five biofertilizers based on native microorganisms promoters of plant growth (NMPPG) as an alternative to the fertilizers used by small vegetable producers. The evaluation was carried out with three types of vegetables (lettuce, celery and epazote) in the Juan Berbera Catalán Irrigation Unit made up by producers from the community of Tixtla, Guerrero. The results show that Rhizobium sp. R01 (Tx3), Azotobacter sp. C3 (Tx1) and Bacillus licheniformis M2-7 (Tx5) used as biofertilizers promote germination and considerably increase fresh weight in these crops, and Azospirillum sp. M9 (Tx2) and Trichoderma sp. ABC1 (Tx4) present significant differences with the negative and chemical control. The yield of lettuce, celery and epazote was favored using biofertilizers, which can be considered a good alternative to apply to these crops, likewise, the price of biofertilizers (5 liters per Tx) compared to the fertilizer DAP-18-46-00 (50 kg) used by the same producers is $1,200.00 vs. $2,000.00 MXN per hectare produced respectively. In conclusion, the biofertilizers used herein represent a feasible alternative for farmers without disregarding the need for technical specialists and producers to identify optimal conditions that support the sustained application and management of biofertilizers.
