OSCILLATION CRITERIA OF A SIXTH-ORDER HALF-LINEAR DIFFERENTIAL EQUATION WITH DE
Authors: Koshkarova Bakhytty , Alday Maktagul , Burgumbayeva Saule
Published: October 2024

В данной работе мы рассматриваем полулинейное дифференциальное уравнение шестого порядка для оператора типа p-Лапласиана с запаздывающим аргументом вида (r(t)|x(v) (t)|p-2 x(v) (t))' +q(t)|x(τ (t))|p-2 x(τ(t))=0. Здесь коэффициенты уравнения удовлетворяют заданным условиям. Линейные и нелинейные дифференциальные уравнения (обыкновенные и в частных производных) с запаздыванием возникают при математическом моделировании явлений и процессов в различных областях теоретической физики, механики, теории управления, биологии, биофизики, биохимии, медицины, экологии, экономики и технических приложениях. Наличие запаздывания в математических моделях и дифференциальных уравнениях является осложняющим фактором, который, как правило, приводит к сужению области устойчивости получаемых решений. Исследование и решение обыкновенных дифференциальных уравнений с запаздыванием по сложности сопоставимы с исследованием и решением уравнений в частных производных без запаздывания. В настоящее время имеется множество работ по изучению различных свойств решений дифференциальных уравнений с запаздыванием. Целью данной работы является изучение осцилляторности рассматриваемого дифференциального уравнения. Для получения критерия осцилляторности используется метод Риккати и доказывается теорема сравнения с дифференциальным уравнением первого порядка с запаздыванием, к которому можно применить известный ранее критерий осцилляторности.

In this article, when a truly new history of independent Kazakhstan is being created today, it is necessary to consider it comprehensively, this is a spiritual requirement arising from the need of the hour to form true views on our past history and generalize it from a scientific and methodological point of view. That is, revise the established guidelines and emphasize their completeness. This is especially necessary for all areas of social scientific research in accordance with the radical political and social changes taking place in the country, including in the field of oratory knowledge, which constitutes a certain part of the history of socio-philosophical thought. However, in the history of Kazakh social thought, based on class ideology, the personality of the judges was not fully revealed and there was no special word. It is clear to all of us that behind class ideology there is an exaggeration in the assertion that the basis of society is economic relations. As a result, absolute importance was given to the idea that man is a totality of social relations. The idea that “it is not man who controls society, but society that controls man” has taken a firm place.

This article presents the results of medium-carbon ferromanganese smelting from domestic manganese ores under large-scale laboratory conditions. Data on the production and demand for refined ferromanganese produced during the last successful year are provided. Since 2020, refined ferromanganese production has decreased by approximately 1,2 million tons, which is 18% lower than in 2019. This decline was caused by the outbreak of the coronavirus (COVID-19), which began in China in 2019, and the subsequent worldwide pandemic, as well as geopolitical conflicts (Russia — Ukraine), which started in 2021. Kazakhstan has significant reserves of manganese ores, which are in ferrous-manganese and carbonate states. X-ray phase analysis showed that manganese in the ores is represented by hydroxide, pyrolusite, and iron oxide. Medium-carbon ferromanganese was smelted in an electric furnace with a transformer power of 0.1 MVA. The chemical composition of the resulting alloy is as follows, %: Mn – 80-85; Si – 0,05-0,25; Fe – 1,8-3,0; P – 0,05-0,09; C – 1,5-2,0; MnO – 20-25; SiO₂ – 13,94-14,5; CaO – 23,35-24,85; MgO – 12,5-14,0. Thus, an optimal technological scheme for the production of a wide range of manganese ferroalloys was developed.

Authors: Malima Mashenene Charles , Hacıkamiloğlu Muhammet Safa , Kurt Orhan
Published: October 2024

Germination and seedling growth periods have a very important function in plant life. Especially in cases where abiotic stress conditions occur, these periods are of vital importance for the sustainability of plant life. Taking this into account, this research was conducted to determine the most suitable temperature for germination and seedling growth parameters of cotton varieties. In this research conducted under controlled conditions, germination and seedling development parameters of two cotton varieties (May-344 and Candia) were tested at 8 different temperature levels (8, 12, 16, 20, 24, 28, 32 and 36°C). It was determined that the germination percentage was 45.17-16.17%, the germination time was 4.06-3.94 days and the emergence rate index was 1.89-0.58 in May-344 and Candia cotton varieties, respectively. Moreover; root length 37.89-16.43 mm, stem length 44.69-41.00 mm, root fresh weight 22.40-19.51 mg, stem fresh weight 90.37-131.80 mg and the root/stem ratio was 0.26-0.16 mg/mg in May-344 and Candia cotton varieties, respectively. The results of the experiment revealed that most of the tested parameters were significantly affected by temperature. The highest germination rate, as the average of the two varieties and for both varieties separately, was obtained at 20 oC and no germination occurred at 8 oC. Except root to shoot ratio, other seedling growth parameters were maximum between 20-32 oC and decreased at higher temperatures.
A novel protease from Bacillus clausii UBBC07, a healthful solution against diarrhea-causing pathogens
Authors: Guleria Jyoti , Khan Mohammad Rashid , Khan Minhaj Ahmad
Published: October 2024

Present treatments for gastroenteritis include the use of antibiotics, probiotics, or spore solutions, which are derived mainly from microbial communities. To avoid multidrug resistance, probiotic bacteria like Bacillus clausii can be of great importance. In the present study, isolation, purification, and physicochemical characterization and bactericidal effect of an extracellularly secreted, novel protease was performed from B. clausii strain UBBC07. In vitro assays, including well-diffusion assay and gel-overlay assay, were used to confirm the anti-diarrheal potential of isolated protein. Molecular weight and the sequence of purified protease were identified by LC-MS/MS. The purified protein’s molecular mass was 23,460 Da. Peptide mass fingerprinting confirmed the novel protein to be a protease with 36% homology to the existing Din b family protein, with strong metalloprotease-like properties. Physicochemical analysis showed that the protein was stable at a broad range of temperatures and pH and retained up to 50% activity at very high temperatures and extreme pH. The efficacy of protein was tested against two major diarrhea-causing pathogens (Bacillus cereus and Salmonella enterica), and the minimum inhibitory concentration obtained was 9.78 μM. The bactericidal effect of purified protein was assayed using time-kill kinetics, where 105 CFU/ml of B. cereus and S. enterica cells were killed in 4 h. Microscopic analysis of Gram-stained bacterial cells also showed debris formation after protease treatment. Researchers have described the impact of resistant bacteria on the long-term prevalence of diarrhea. This situation inspires researchers to come up with more cost-effective and high-efficacy alternatives like proteases to treat this disease.
Discusiones interdisciplinarias sobre persistencia colonial, descolonización, experiencia y pasajes socioantropológicos y políticos latinoamericanos
Authors: Ávila Rojas Odín , Matamoros Ponce Fernando , Melgarejo Pérez Manuel Alfonso
Published: October 2024

A central debate in contemporary Latin American social sciences revolves around the enduring presence of colonial patterns, practices, and forms of domination in research methodologies and the subjective framing of societal issues. However, decolonizing initiatives are emerging, concurrently, to challenge the ways coloniality has been entwined with the expansion of capital in the 21st century. This introductory article explores the key debates surrounding colonial persistence and decolonization within the social sciences. The dossier employs a methodology centered on documentary analysis and participatory social and political reflection, particularly through experimental approaches. The articles reviewed reveal that colonial persistence and decolonization are inherently dialectical, contradictory, and conflict-ridden, manifesting across diverse social, cultural, economic, and political domains. The uniqueness of this thematic issue lies in its ability to weave together a theoretical and conceptual discourse on symbolic and imaginary aspects within culture, spanning anthropological, legal, and educational dimensions. The analysis underscores that these issues are pluralistic and deeply intertwined with struggles over land and natural resources, enriching interdisciplinary understanding of the complex dialectical relationships between social, anthropological, economic, and political factors, alongside the aesthetics of cultural practices.
Estado de excepción neoliberal y resistencia en el sureste de México
Authors: Vázquez García Agustín R. , Zárate Santiago Aline
Published: October 2024

In November 2021, the President of Mexico (2018-2024) declared that the priority megaprojects of the National Development Plan (Maya Train, Isthmus of Tehuantepec Interoceanic Corridor, Dos Bocas Refinery) fall within the realm of national security. Public and private investments in these projects are directed towards southeastern Mexico, covering the states of Oaxaca, Chiapas, Quintana Roo, Campeche, Yucatán, and Tabasco. These regions are home to indigenous peoples and communities that hold 45% of Mexico’s total social property. In some cases, these communities are visibly linked to national political organizations that defend land and territory. The decree is considered a state of exception applied to land-territory use, with dual implications. On one hand, it represents the undivided social field monopolized by monetary metrics. On the other hand, it signifies the expansion of a neocolonial condition promoted by the Mexican federal government, which marginalizes the voice of resistance in favor of adopting the capital logic defined by the stratification of the global economy. The methodology involves participatory action research since 2019, collaborative research through the coordination of workshops, caravans, marches, and political-community meetings, promoted in conjunction with assemblies fighting for territorial defense. We anticipate the increased use of such state of exception in response to the intertwined rise of health, environmental, and economic contingencies that drive the economic cycle, coupled with ineffective governmental policies formulated for regular times. In other words, the state of exception is activated to ensure the continuity of capital accumulation driven by the concentration of private property.
“Plomo por hablar, plata pa’ que hablemos”. Diversidad étnica y educación en el suroccidente colombiano
Authors: Revelo Calvache Jose Luis
Published: October 2024

How do the relationships between the concept of being indigenous and the processes of ethnoeducation manifest in southwestern Colombia? This ethnographic study explores the complexities of constructing ethnic identity among the indigenous peoples of Nariño, focusing on the implementation of educational programs driven by a population perspective. By questioning the foundations of ethnoeducation from the late 20th century to the early 21st century, we establish a dialogue among various institutional agents within the broader framework of ethnic-based social organization. We also examine the historical relationships, institutional archaisms, and contemporary challenges faced by ethnic educational processes in Nariño. We conclude with insights into the construction of ethnic identity and its implications for the social order governing the interactions between community members and government representatives. We conceptualize the relationship between the State, school, and ethnic identity as a fundamental part of Colombia’s modern project, which has been in development since the republican era. The institutional framework has fluctuated between protectionist, paternalistic, and cultural assimilation policies. However, the current threats to the physical and cultural survival of ancestral peoples must be addressed through the State’s institutional mechanisms and governance technologies. These mechanisms are designed to tackle the challenges of interculturality within a complex and often contradictory framework of relationships.

The oviduct is the site of fertilization and preimplantation embryo development in mammals. Evidence suggests that gametes alter oviductal gene expression. To delineate the adaptive interactions between the oviduct and gamete/embryo, we performed a multi-omics characterization of oviductal tissues utilizing bulk RNA-sequencing (RNA-seq), single-cell RNA-sequencing (scRNA-seq), and proteomics collected from distal and proximal at various stages after mating in mice. We observed robust region-specific transcriptional signatures. Specifically, the presence of sperm induces genes involved in pro-inflammatory responses in the proximal region at 0.5 days post-coitus (dpc). Genes involved in inflammatory responses were produced specifically by secretory epithelial cells in the oviduct. At 1.5 and 2.5 dpc, genes involved in pyruvate and glycolysis were enriched in the proximal region, potentially providing metabolic support for developing embryos. Abundant proteins in the oviductal fluid were differentially observed between naturally fertilized and superovulated samples. RNA-seq data were used to identify transcription factors predicted to influence protein abundance in the proteomic data via a novel machine learning model based on transformers of integrating transcriptomics and proteomics data. The transformers identified influential transcription factors and correlated predictive protein expressions in alignment with the in vivo-derived data. Lastly, we found some differences between inflammatory responses in sperm-exposed mouse oviducts compared to hydrosalpinx Fallopian tubes from patients. In conclusion, our multi-omics characterization and subsequent in vivo confirmation of proteins/RNAs indicate that the oviduct is adaptive and responsive to the presence of sperm and embryos in a spatiotemporal manner.

The biosynthesis of cAMP by mammalian membrane-bound adenylyl cyclases (mACs) is predominantly regulated by G-protein-coupled-receptors (GPCRs). Up to now the two hexahelical transmembrane domains of mACs were considered to fix the enzyme to membranes. Here we show that the transmembrane domains serve in addition as signal receptors and transmitters of lipid signals that control Gsα-stimulated mAC activities. We identify aliphatic fatty acids and anandamide as receptor ligands of mAC isoforms 1 to 7 and 9. The ligands enhance (mAC isoforms 2, 3, 7, and 9) or attenuate (isoforms 1, 4, 5, and 6) Gsα-stimulated mAC activities
in vitro
and
in vivo
. Substitution of the stimulatory membrane receptor of mAC3 by the inhibitory receptor of mAC5 results in a ligand inhibited mAC5-mAC3 chimera. Thus, we discovered a new class of membrane receptors in which two signaling modalities are at a crossing, direct tonic lipid and indirect phasic GPCR-Gsα signaling regulating the biosynthesis of cAMP.
Genetic Inactivation of the β1 adrenergic receptor prevents Cerebral Cavernous Malformations in zebrafish

Propranolol reduces experimental murine cerebral cavernous malformations (CCMs) and prevents embryonic caudal venous plexus (CVP) lesions in zebrafish that follow mosaic inactivation of
ccm2
. Because morpholino silencing of the β1 adrenergic receptor (
adrb1
) prevents the embryonic CVP lesion, we proposed that
adrb1
plays a role in CCM pathogenesis. Here we report that

adrb1
-/-

zebrafish exhibited 86% fewer CVP lesions and 87% reduction of CCM lesion volume relative to wild type brood mates at 2dpf and 8-10 weeks stage, respectively. Treatment with metoprolol, a β1 selective antagonist, yielded a similar reduction in CCM lesion volume.

Adrb1
-/-

zebrafish embryos exhibited reduced heart rate and contractility and reduced CVP blood flow. Similarly, slowing the heart and eliminating the blood flow in CVP by administration of 2,3-BDM suppressed the CVP lesion. In sum, our findings provide genetic and pharmacological evidence that the therapeutic effect of propranolol on CCM is achieved through β1 receptor antagonism.
Adaptive prototype few-shot image classification method based on feature pyramid
Authors: Shen Linshan , Feng Xiang , Xu Li , Ding Weiyue
Published: October 2024

Few-shot learning aims to enable machines to recognize unseen novel classes using limited samples akin to human capabilities. Metric learning is a crucial approach to addressing this challenge, with its performance primarily dependent on the effectiveness of feature extraction and prototype computation. This article introduces an Adaptive Prototype few-shot image classification method based on Feature Pyramid (APFP). APFP employs a novel feature extraction method called FResNet, which builds upon the ResNet architecture and leverages a feature pyramid structure to retain finer details. In the 5-shot scenario, traditional methods for computing average prototypes exhibit limitations due to the typically diverse and uneven distribution of samples, where simple means may inadequately reflect such diversity. To address this issue, APFP proposes an Adaptive Prototype method (AP) that dynamically computes class prototypes of the support set based on the similarity between support set samples and query samples. Experimental results demonstrate that APFP achieves 67.98% and 85.32% accuracy in the 5-way 1-shot and 5-way 5-shot scenarios on the MiniImageNet dataset, respectively, and 84.02% and 94.44% accuracy on the CUB dataset. These results indicate that the proposed APFP method addresses the few-shot learning problem.
Sistema de Jardines para el Valle del Huasco: Refugios de quebrada para la articulación del paisaje emergente frente a escenarios de vulnerabilidad hídrica
Authors:   , Díaz Oyarzún Carlos
Published: October 2024

La zona centro norte de Chile experimenta un escenario de vulnerabilidad hídrica que hace susceptible a los paisajes productivos como paisajes en emergencia, pues implica una amenaza latente para la supervivencia de los habitantes de estos sitios. A partir del análisis de las distintas capas que componen el paisaje de la subcuenca del Valle del Huasco (morfológica, hidrológica, productiva, ecológica, y de asentamientos) se propone un ‘sistema de jardines’ para la domesticación y articulación de este paisaje en emergencia. Estos se ubicarían en ocho puntos entre Huasco y Vallenar donde confluyen las quebradas más importantes de este tramo con el río y se localizan centros poblados (lo urbano), los que se buscan articular a las dinámicas productivas y ecológicas del lugar. Se entenderá cada jardín como un inter-medio que forma parte de una matriz o red interconectada de sistemas ecológicos específicos y que permitirían configurar sitios de refugio frente a escenarios de incertidumbre y vulnerabilidad climática e hídrica.
ESTRATEGIA DE COMUNICACIONES PARA MUNICIPALIDAD DE LA FLORIDA. PLAN DE ACCIÓN PARA POTENCIAR RECURSOS HUMANOS Y TECNOLÓGICOS PARA LA GESTIÓN MUNICIPAL EN EL TERRITORIO
Authors:   , Vargas Lobos Miguel
Published: October 2024

El proyecto de título titulado "Estrategia de Comunicaciones para la Municipalidad de La Florida" tiene como objetivo principal mejorar la percepción y la gestión municipal en el sector precordillerano de la comuna, específicamente en las Unidades Vecinales N° 1 (Alto Macul) y N° 2 (Lo Cañas y Rojas Magallanes Oriente). Estas áreas, habitadas mayoritariamente por familias de nivel socioeconómico medio-alto, han sido descuidadas por la actual administración municipal, liderada por el alcalde Rodolfo Carter, quien ha priorizado sectores más vulnerables de la comuna. Este descontento en el sector ha provocado que los vecinos sientan una falta de atención a sus necesidades, lo que ha generado una percepción de abandono por parte de la Municipalidad. Para contrarrestar esto, el proyecto plantea una estrategia de comunicaciones que tiene como fin mejorar la relación entre la Municipalidad y los vecinos, así como su percepción sobre la gestión de servicios municipales. El plan de acción está estructurado en tres grandes lineamientos: Vinculación: Involucrar a los dirigentes vecinales en espacios de toma de decisiones para fomentar el diálogo con las autoridades municipales y generar un ambiente de cooperación. Comunicación: Aumentar el conocimiento público sobre los Coordinadores Territoriales y las acciones municipales. Esto incluye la implementación de códigos QR para que los vecinos puedan comunicarse de manera más directa y eficiente con sus coordinadores territoriales. Planificación: Mejorar la planificación y gestión de solicitudes vecinales mediante la apertura de nuevos canales de comunicación comunitaria, como grupos de WhatsApp específicos para cada Unidad Vecinal, donde se gestionarán consultas y comunicaciones importantes. Además, el proyecto incluye una fase de evaluación basada en indicadores clave de desempeño (KPI), como el porcentaje de satisfacción vecinal y el número de solicitudes atendidas. En términos tecnológicos, se plantea la creación de una sección web y código QR en la que los vecinos puedan acceder a información detallada y personalizada sobre sus coordinadores territoriales, aumentando la transparencia y la eficiencia en la gestión municipal. Este plan tiene un enfoque integral que no solo busca abordar las deficiencias actuales en la comunicación entre la Municipalidad y los vecinos, sino también promover una gestión más participativa, transparente y eficiente, fortaleciendo la confianza y colaboración entre ambas partes.

Indian retail market is one of the most complicated and dynamic industry which is contributing to more than 10% of the country’s gross domestic product (GDP) and around 8% of the employment. Mainly it is dominated by unorganized retailers, in last 10 years gradual shifts, like entry of modern trade, the entry of cash and carry, the advent of the e-commerce revolution and, more recently, the growth in newage B2B providers have started to transform this ecosystem, this makes retailers to go for online purchase of grocery using e- B2B platforms. Keeping this background in mind, the study was conducted in Bengaluru city with sample size of 250 retailers using primary as well as secondary data. The data was analysed using percent analysis, frequency, weighted average mean and Garrett ranking method. The study reveals that retail sector in study area is dominated by male ownership, most of the retailers were aged above 45 years having basic level of education and have more than 15 years of experience in retailing. Factors such as convenience, price, and wide product availability are the primary factors influencing online purchases, with convenience having the highest WAM score 4.2. All the surveyed retailers are aware of online grocery applications, indicating a high penetration of digitalization in the area. Retailers predominantly order once or twice a week, with most orders value between 700-3000 rupees, reflects the use of online platforms for regular stock replenishment. Main problems faced by retailers were delivery of damaged product, return issues and minimum order value and these were the main factors influencing them to stay away from online purchase.

A field experiment was conducted to know the effect of terminal heat stress on seed yield and its mitigation in chickpea was carried out during 2021-22 at Seed Unit, University of Agricultural Sciences, Raichur. High temperature during sowing time from early to late and very late directly affect the vegetative and anthesis stages and it was overcome by spraying the plants with heat stress mitigating chemicals. The experiment was laid out with three dates of sowing and ten foliar spray each treatment was replicated twice in a split plot design. Spraying was done at two stages of crop growth i.e., at vegetative (35-40 DAS) and anthesis stage (50-60 DAS) in all dates of sowing. The interaction between dates of sowing and heat stress mitigating chemicals showed highest physiological and seed quality parameters i.e. chlorophyll stability index (D3T3) (73.06 and 74.63%), minimum cell membrane injury index (55.09 and 63.63 %), maximum proline content (D3T3) (6.79 and 9.37 µ mol g-1), relative water content (83.79 and 75.10 %) at 60 DAS and at harvest, first count (90.50 %), final count (100.00 %), speed of germination (43.80), minimum time for radicle emergence (41.00 hrs), root length (17.32 cm), shoot length (10.12 cm), dry weight (27.10 mg), seedling vigour index-I (2643), seedling vigour index-II (2700). Among the treatments, sowing done at October 15th and plants sprayed with salicylic acid @ 400 ppm followed by gibberellic acid (100ppm) (T10) twice at vegetative and anthesis stage was found to be better in obtaining significantly higher physiological and seed quality parameters in chickpea variety JG-11 under heat stress conditions.

To transform the cropping pattern or add a new potato variety like ACI Alu-10 (Valencia) to the existing cropping pattern, it is essential to have adequate farmers’ knowledge and a favorable attitude towards that variety. In addition, the better performance of the variety in comparison to other market leader varieties is also necessary. Against such a backdrop, the present study determined farmers’ knowledge and attitude towards the potato variety (Valencia) and compare the selling price, yield, harvesting period, and cost of production of this variety with other potato varieties. Data were collected from randomly selected 139 farmers of Bogura and Joypurhat districts. A face-to-face interview followed by a structured questionnaire were used to collect data. The survey revealed that the Valencia users had higher knowledge and a more favorable attitude towards the variety than the non-Valencia users. The t-test showed a significant difference between Valencia users and non-Valencia users regarding the price, harvesting period, and cost of production, indicating that Valencia has a shorter harvesting period, higher selling price, and lower production cost. On the other hand, the result indicates that 62 days Valencia yield was almost near to the 74 days of other check potato varieties yield. By getting early and higher cash through selling Valencia, farmers can utilize the amount to improve their livelihood and solve problems. The findings may be helpful to policymakers in the decision to include Valencia in the current cropping pattern to increase potato production and food security in Bangladesh.
