Purpose: This study aims to assess the biodiversity of Cucurbita maxima pollinators with a view to optimising the expected results, in a context of efficient and sustainable agriculture in Cameroon.
Methodology: In Vogzom (North), and in Torok (Far North) in 2022, Cucurbita maxima flowers (Cucurbitaceae) were observed in order to evaluate agronomic parameters, identify the floricultural entomofauna and the pollinating activity of Apidae. For the characterization of the floricultural entomofauna in Vogzom and Torok, five treatments of 30 female flowers each were established according to whether they were protected from visits by Apis mellifera (T0) or benefited from one visit (T2), two (T3), three visits (T4) each or were free (T1). A recognition code was assigned to each visiting species of Cucurbita maxima flowers and a few individuals of each species were captured and retained for later identification. The data collected was codified and encoded in the Excel spreadsheet of the Microsoft Office 2019 program. The normality test of the different variables was done by the Shapiro-Wilk test at the 5% significance level. The Tukey test was used for the comparison of means when the p-value was ˃ 5% and otherwise, the nonparametric Kruskal-Wallis test was used.
Finding: The floricultural entomofauna associated with pumpkin consists of five species in Vogzom and fourteen species in Torok. Apidae (82.06%) were in the majority; represented by Apis mellifera (82.06%) in Vogzom. Similarly in Torok, Apidae (77.55%) were in the majority, represented by Apis mellifera with a relative abundance of 40.5%. The daily activity of the Apidae was effective between 6 a.m. and 1 p.m. with a morning peak of activity (6 a.m. to 7 a.m.) in both sites. Floral visits to collect nectar (74%) were more important than those devoted to pollen (26%) in A. mellifera. In Vogzom as well as in Torok. The fruiting and mature fruit rates as well as their average mass vary according to the number of successful insect visits by the female flowers.
Contributions to theory, policy and practice: Overall, the fruit and seed production of Cucurbita maxima is closely dependent on the pollinating activity of the Apidae; without it, no fruit or seed is formed, as the pumpkin is neither parthenocarpic nor apomictic. Obtaining optimal pumpkin yields is conditioned by the conservation and protection of pollinator biodiversity.

Published: February 2025

O presente estudo visa analisar a aprendizagem significativa através do uso das tecnologias digitais, observando aspectos inovadores que podem potencializar as práticas docentes no ensino. Nos dias atuais, os mecanismos tecnológicos têm se tornado incidentes e recorrentes ao se referir a elaboração de aulas. É perceptível que a motivação e o engajamento dos alunos são aprimorados com o uso das tecnologias, dessa forma explorando-as através de plataformas digitais e de gamificação. A metodologia adotada para este estudo foi de forma qualitativa. A amostra foi composta por 35 alunos de uma turma de eletiva, os quais integram os 1º anos A, B e C do Ensino Médio. O modelo inovador de ensino foi confrontado com o tradicional ao utilizar jogos educacionais e plataformas tecnológicas interativas, tais como Kahoot!, Quizizz, Wordwall, Google Forms, Software (PowerPoint) e Lingo Clip. Tais recursos foram incrementados mediante o uso de celulares, tablets, netobook, datashow e internet principalmente. A coleta de dados foi realizada por meio de sondagens antes e depois das intervenções, questionários de percepção sobre o uso de tecnologias e gamificação, além de observações diretas em sala de aula. Os resultados foram obtidos através do uso das tecnologias digitais e das metodologias ativas, que possibilitaram um avanço significativo na aprendizagem e impulsionaram a motivação dos estudantes. Neste cenário, torna-se um desafio que o aluno disponibilize tais ferramentas digitais para que possa romper com a passividade e o tradicionalismo na sala de aula; ademais um outro obstáculo é que essa metodologia não deve causar uma exclusão ao aluno que não possua a ferramenta necessária. O uso das Tecnologias Digitais para a aula torna-se um forte aliado para fornecer práticas inovadoras e que propiciem ferramentas para aprendizagens dos alunos. A prática docente assume então alguns desafios diante das novas demandas tecnológicas, entre eles há uma necessidade da formação para apoiar os professores, com foco na utilização dos recursos tecnológicos como apoio ao ensinar e ao aprender. Enfim, a pesquisa prisma analisar como tais mecanismos contribuem para a melhoria dos processos educacionais, o empenho dos alunos no que se refere a aprendizagem significativa, além de identificar fatores que podem otimizar sua aplicação em diferentes níveis de ensino.

Abstract. The aim of this study is to determine the effects of different treatments used to synchronize follicular waves prior to superstimulation of responses and in vitro embryo production (IVEP). The study used 12 healthy Holstein heifers. In GnRH + P4, an intravaginal progesterone (P4) device was inserted into the vagina on a random day of the estrous cycle, and 10 µg of the gonadotropin-releasing hormone (GnRH) was administered intramuscularly at the same time. After these applications, 25 mg of PGF2α was administered intramuscularly on the third and fourth days of treatment. The intravaginal progesterone device was removed on day 5. At the same time, 125 µg of follicle-stimulating hormone (FSH) was administered intramuscularly as a single dose. Two days after the FSH injection, oocytes were retrieved using transvaginal ultrasound. In contrast to GnRH + P4, hCG + P4 was performed with 1500 IU hCG (human chorionic gonadotropin) injection instead of GnRH. In DFR + P4, dominant follicles were removed. In the control group, the oocytes were collected on a random day of the estrous cycle. The ovarian follicles were measured by ultrasound prior to oocyte collection. The number of medium-diameter follicles (3–8 mm) was found to be greater in hCG + P4 and DFR + P4 than in the control group (p<0.05). It was determined that the numbers of viable oocytes, Grade A oocytes, cleaved oocytes, and blastocysts obtained per ovum pickup (OPU) were greater in hCG + P4 and DFR + P4 than in the control group (p<0.05). In addition, the numbers of Grade A oocytes and blastocysts obtained per OPU were greater in the DFR + P4 group than in the GnRH + P4 group (p<0.05). As a result, it was thought that synchronization of follicular wave emergence with DFR and hCG in the short synchronization protocols used before superstimulation could increase the success rate of OPU/IVEP programs.

Abstract. The rapid development of the economy and the implementation of environmental policies adapted in India have led to fast changes of regional SO2 emissions. We present a monthly SO2 emission inventory for India covering December 2018 to November 2023 based on the Tropospheric Monitoring Instrument (TROPOMI) Level-2 COBRA SO2 dataset, using an improved flux-divergence method and estimated local SO2 lifetime, which includes both its chemical loss and dry deposition. We update the methodology to use the daily CAMS model output estimates of the hydroxyl-radical distribution as well as the measured dry deposition velocity to account for the variability in the tropospheric SO2 lifetime. It is the first effort to derive the local SO2 lifetime for application in the divergence method. The results show the application of the local SO2 lifetime improves the accuracy of SO2 emissions estimation when compared to calculations using a constant lifetime. Our improved flux-divergence method reduced the spreading of the point-source emissions compared to the standard flux-divergence method. Our derived averaged SO2 emissions covering the recent 5 years are about 5.2 Tg yr−1 with a monthly mean uncertainty of 40 %, which is lower than the bottom-up emissions of 11.0 Tg yr−1 from CAMS-GLOB-ANT v5.3. The total emissions from the 92 largest point-source emissions are estimated to be 2.9 Tg yr−1, lower than the estimation of 5.2 Tg yr−1 from the global SO2 catalog MSAQSO2LV4. We claim that the variability in the SO2 lifetime is important to account for in estimating top-down SO2 emissions.

Abstract. We estimate the sub-surface energy budget and heat fluxes in the coarse-blocky active layer (AL) of the Murtèl rock glacier, a seasonally snow-covered permafrost landform located in the eastern Swiss Alps. In the highly permeable AL, conductive/diffusive heat transfer including thermal radiation, non-conductive heat transfer by air circulation (convection), and heat storage changes from seasonal accretion and melting of ground ice shape the ground thermal regime. We quantify individual heat fluxes based on a novel in-situ sensor array in the AL and direct observations of the ground ice melt in the years 2020–2022. Two thaw-season mechanisms render Murtèl rock glacier comparatively climate-resilient. First, the AL intercepts ~70 % (55–85 MJ m−2) of the thaw-season ground heat flux by melting ground ice that runs off as meltwater, ~20 % (10–20 MJ m−2) is spent on heating the blocks, and only ~10 % (7–13 MJ m−2) is transferred into the permafrost body beneath and causes slow permafrost degradation. Second, the effective thermal conductivity in the ventilated AL increases from 1.2 W m−1 K−1 under strongly stable temperature gradients to episodically over 10 W m−1 K−1 under unstable temperature gradients, favouring convective cooling by buoyancy-driven Rayleigh ventilation (thermal semiconductor effect). In winter, radiatively cooled air infiltrating through a discontinuous, semi-closed snowcover leads to strong AL cooling. The two characteristic parameters (effective thermal conductivity and intrinsic permeability) are sensitive to debris texture, hence these convective undercooling processes are specific to highly permeable coarse-blocky material.

Published: February 2025

Este artículo emerge desde un proyecto de investigación[1] que pone en perspectiva la importancia que tiene el currículo universitario para formar una cultura de paz y el problema se centra en la manera como una universidad desarrolla una propuesta formativa que se refleje en las vivencias de sus estudiantes. Reconocer esa importancia del currículo en el desarrollo de una educación para la paz, es el objetivo general, y los objetivos específicos son: identificar lo que propone el currículo en materia de formación para la paz, describir las percepciones de los estudiantes en cuanto a la educación para la paz y contrastar el ideal de formación con la realidad de los estudiantes respecto a la educación para la paz. El proyecto tiene un enfoque cualitativo y se abordará con un diseño fenomenológico para contrastar lo que propone la universidad con las experiencias de los estudiantes frente a la paz. Como técnicas se emplearon entrevistas, grupos de discusión y análisis de contenido. El contexto fue la Corporación Universitaria Minuto de Dios - UNIMINUTO sede Bello (Antioquia – Colombia) y los sujetos de investigación fueron estudiantes principalmente de últimos semestres. Como resultado se encontró que toda propuesta formativa cobra sentido cuando los estudiantes pueden relacionar sus aprendizajes con un contexto real; a su vez, un currículo cualquiera que sea su intención cobra vida desde las prácticas docentes; entonces, serán los profesores quienes generen de manera intencionada espacios que reflejen una cultura de paz.

Исследование направлено на разработку мультимодальной нейронной сети для улучшения точности обнаружения препятствий путём комбинирования тепловизионных данных с информацией, полученной от других типов датчиков, таких как лидары (системы лазерного дальномера) и ультразвуковые датчики. В контексте автономных систем, таких как роботы и беспилотные летательные аппараты (дроны), эффективное слияние данных с различных датчиков является ключевым аспектом для обеспечения безопасного обхода препятствий и навигации в сложных условиях окружающей среды. Особое внимание уделяется тепловизионной камере как источнику, который предоставляет ценную информацию о температурных характеристиках объекта, что может быть особенно полезно в условиях низкой видимости или ночью. Однако тепловизионные данные могут быть ограничены в отношении точности определения формы и расстояния до объектов. В свою очередь, лидары и ультразвуковые датчики предлагают высокую точность в измерении расстояний и формы объектов, но могут сталкиваться с ограничениями при определении температурных свойств. Результатом является значительное повышение точности обнаружения препятствий и улучшение способности системы к самостоятельной навигации и принятию решений в реальном времени.

В статье исследуются процессы внешней миграции, проходящие в странах Центральной Азии в контексте их влияния на национальную безопасность. Внимание уделяется причинам и факторам эмиграции квалифицированных специалистов, студенческой молодежи за пределы Центральной Азии. Помимо экономических факторов внешней миграции рассматриваются также неэкономические факторы, такие как репатриация, политические мотивы и экологические проблемы. Авторы приходят к выводу о том, что миграционная система региона претерпела значительные изменения, превратившись в регион эмиграции. Страны региона еще находятся на этапе разработки эффективной миграционной политики и не имеют должного уровня контроля над внешней миграцией.

The authors examine external migration in the countries of Central Asia in the context of its impact on national security. Attention is paid to the reasons and factors for the emigration of qualified specialists and students outside Central Asia. In addition to the economic factors of external migration, non-economic factors such as repatriation, political motives and environmental problems are also considered. The authors come to the conclusion that the migration system of the region has undergone significant changes, turning into a region of emigration. The countries of the region are still at the stage of developing an effective migration policy and do not have the proper level of control over external migration.
