Evaluación comparativa de los algoritmos de aprendizaje automático Support Vector Machine y Random Forest
Authors: Garzón Barrero Julián , Sánchez Pineda Nancy Estela , Londoño Pinilla Darío Fernando
Published: January 2024

En el presente estudio se examinó el rendimiento de los algoritmos Support Vector Machine (SVM) y Random Forest (RF) utilizando un modelo de segmentación de imágenes basado en objetos (OBIA) en la zona metropolitana de Barranquilla, Colombia. El propósito fue investigar de qué manera los cambios en el tamaño de los conjuntos de entrenamiento y el desequilibrio en las clases de cobertura terrestre influyen en la precisión de los modelos clasificadores. Los valores del coeficiente Kappa y la precisión general revelaron que svm superó consistentemente a RF. Además, la imposibilidad de calibrar ciertos parámetros de SVM en ArcGIS Pro planteó desafíos. La elección del número de árboles en RF mostró ser fundamental, con un número limitado de árboles (50) que afectó la adaptabilidad del modelo, especialmente en conjuntos de datos desequilibrados. Este estudio resalta la complejidad de elegir y configurar modelos de aprendizaje automático, que acentúan la importancia de considerar cuidadosamente las proporciones de clases y la homogeneidad en las distribuciones de datos para lograr predicciones precisas en la clasificación de uso del suelo y cobertura terrestre. Según los hallazgos, alcanzar precisiones de usuario superiores al 90 % en las clases de pastos limpios, bosques, red vial y agua continental, mediante el modelo svm en ArcGIS Pro, requiere asignar muestras de entrenamiento que cubran respectivamente el 2 %, 1 %, 3 % y 8 % del área clasificada.

Authors: Annisa Qurrata Vika , Hakimi Mohd. Shafiai Muhammad , Alma'amun Suhaili , Wahid Hairunnizam , Ismail Abdul Ghafar , Purwanti Pudji
Published: January 2024

Blue forests are areas that protect the coastline from flooding and erosion. They harbor wildlife and provide a sustainable livelihood for communities. One of the blue forest types is mangrove forest. Indonesia has the most expansive mangrove forest area in Southeast Asia, but nearly 25% has been deforested. Maintaining the sustainability of mangrove forests is one of the sustainable development goals (SDG) 14. Therefore, to achieve this goal, financing is needed to support the needs in maintaining the sustainability of mangrove forests. This paper is a conceptual framework that provides an Islamic social finance-based funding model for the blue forest sector. This program is called Blue Waqf. In order to implement this program, Indonesian Waqf Board and registered nazir are needed as the program’s coordinators. In addition, a colossal campaign needs to be conducted. The involvement of the surrounding community as a social adaptor is also vital. Last, waqf management through blue waqf requires protection from takaful/project guarantees. It has to be done to minimize the economy. The impact will be sustainable for the economy, society, and the environment. The profits obtained from blue waqf will be distributed to beneficiaries.

Consideraciones para una estética monstruosa en el horror corporal de Julia Ducournau: un análisis desde la otredad y la subversión
Authors: SÁNCHEZ TIERRASECA MÓNICA
Published: January 2024

Este análisis se centra en la obra cinematográfica de la directora y guionista francesa Julia Ducournau y su representación de la otredad y la subversión a través de la monstruosidad. Empleando una metodología cualitativa, se destacan las características que presentan los personajes de sus películas, como el enfoque en la representación de lo monstruoso como metáfora, personificado en seres inadaptados que buscan, de distintas maneras, encajar en la sociedad a pesar de sus diferencias. Asimismo, se enfatiza el uso imágenes gráficas y grotescas del cuerpo humano para mostrar el horror corporal y la intención de establecer una conexión con la otredad desafiando los ideales estéticos convencionales. Todo ello, aunado a la amalgama de elementos de terror, drama o ficción que combina en su obra, convierte al cine de Ducournau en una experiencia distintiva sumándose a la invitación para reflexionar sobre la existencia de una estética monstruosa.

Cuando las señales del tiempo son la inspiración. La entrevista al artista vs. lo digital para catalogación y conservación de arte urbano
Authors: MORAL RUIZ CARMEN , LUQUE RODRIGO LAURA
Published: January 2024

Las obras contemporáneas, en concreto el caso del arte urbano y el muralismo, son construidas a través de una compleja red basadas en el contexto y el soporte en el que se insertan. Estas manifestaciones están caracterizadas, en muchos casos, por ser efímeras, inspirando las ideas de los artistas y caracterizando sus opiniones sobre la conservación de sus piezas. En esta aportación se recogen opiniones de artistas sobre la documentación y la conservación material de sus obras, para comprender las diversas posturas al respecto y mostrar el abanico de casuísticas de conservación en manifestaciones que, desde su concepción, están pensadas para degradarse y desaparecer. Esas señales del tiempo construyen la obra, modificando su apariencia, y mostrando la importancia de la catalogación y documentación a través de tecnologías digitales aplicadas a la conservación y restauración entre las que cabe citar la fotografía, la fotogrametría y la microscopía digital.

Ensayos visuales, ensayos fílmicos y video-instalación en la investigación artística
Authors: NARVÁEZ GEOVANNY
Published: January 2024

Este artículo propone una reflexión sobre el ensayo visual, el ensayo fílmico y la video-instalación en los procesos de investigación artística. El tema y motivo de inspiración de este proyecto artístico proviene de Tiempo de mujeres (1987) de Mónica Vásquez, un documental que retrata la vida cotidiana de Santa Rosa, un pueblo del cantón Cuenca habitado por mujeres y niños, debido a la migración masculina hacia los Estados Unidos. Centrado en la investigación-creación, el Grupo de Investigaciones Cinematográficas (GIC - UCUENCA) plantea a artistas y artistas-investigadores, luego del visionado del documental, un retorno, una (re)visita hacia ese pueblo después de casi cuatro décadas para registrar en imágenes fijas y en movimiento posibles permanencias o cambios, resultados que se exhibirán en una video-instalación. En este sentido, cobra interés el proceso creativo y la aplicación de distintos métodos, técnicas y poéticas cuyas obras en proceso (work in progress), en una mise en abîme, se presentan aquí en formato de ensayo visual.

Ampliando el círculo: cómo elijo ser quien me dé la gana de ser
Authors: SAMUDIO GRANADOS MARCELA
Published: January 2024

La definición de feminismos como “conquista” de derechos se queda corta en el momento en el que también se lo piensa como esa mirada otra, que nos guía para significar y resignificar constantemente formas diversas de ser, sentir y vivir. En cada momento histórico y cultural existe un canon patriarcal establecido, una especie de círculo que lo permea todo con la omnipresencia masculina en las diferentes prácticas científicas, artísticas y culturales. En este artículo se hace un pequeño recorrido por la historia del arte, la literatura, la fotografía y el cine, para que nos cuestionemos sobre ese canon o círculo imaginario que define lo que está cultural y artísticamente aceptado o no, además de que existan más posibilidades de apreciar esas miradas otras, en este caso femeninas, que enriquezcan el círculo y lo transformen.

Práticas de ensino na alfabetização
Authors: José Barbosa Maria , Silva Mesquita Elizangela , Souza de Castro Lílian
Published: January 2024

O desenvolvimento de práticas de escrita que considerem os saberes dos educandos nos anos iniciais do ensino fundamental, favorecendo o seu protagonismo no processo de alfabetização, ainda representa um grande desafio para os professores do ciclo de alfabetização. Nesse sentido, tem-se como objetivo analisar práticas de ensino para a apropriação da escrita por crianças do ciclo de alfabetização do ensino fundamental, tendo a linguagem como forma de interação e interlocução no contexto escolar da alfabetização. Tomaremos como referência Vigotski, (2007; 2018) e Smolka (1988), Goulart, Gontijo, et al. (2017) concernente à perspectiva discursiva na apropriação dessa linguagem. A metodologia adotada para elaboração do estudo consiste na reflexão sobre os pressupostos da Alfabetização Discursiva a partir da análise da prática pedagógica de uma professora da turma de 2º ano do ensino fundamental de uma escola municipal de Fortaleza-Ceará. Conclui-se a relevância de os professores alfabetizadores refletirem sobre sua prática pedagógica e compreenderem que a alfabetização não consiste em um ato mecânico de ler e escrever, mas em um processo de interação e interlocução entre os professores e as crianças, além disso, precisam perceber que a escrita é uma prática social da qual as crianças se apropriam e participam.
Pierogi kulinarną wizytówką „wędrownego ambasadora Polski” Władysława Grodeckiego
Authors: Grunwald Jadwiga
Published: January 2024

Pierogi – kawałki cienkiego, elastycznego i dobrze ciasta napełnione słonym lub słodkim nadzieniem i ugotowane we wrzącej wodzie – to jedno z najstarszych, a jednocześnie niezwykle popularnych dań kuchni polskiej. Niektórzy postrzegają je jako swego rodzaju polską „wizytówkę” i ważny element przybliżający walory polskiej kultury i tradycji. Podobny pogląd wyrażał w swojej twórczości znany polski podróżnik Władysław Grodecki (1942–2018). W jego portfolio znajduje się ponad sto wyjazdów zagranicznych, w tym trzy samotne podróże dookoła świata. Niezwykłe osiągnięcia Grodeckiego zapewniły mu powszechne uznanie i szacunek, choć jego droga do sukcesu przebiegała przez wiele trudnych etapów.
W związku z jego działalnością na rzecz promocji polskiej kultury i historii za granicą, w polskiej prasie zaczęto określać go mianem „wędrownego ambasadora Polski”. Gotowanie pierogów dla gospodarzy i przyjaciół było często integralną częścią jego podróży. Spuścizna Grodeckiego obejmuje ponad 250 artykułów prasowych i 300 wpisów autobiograficznych na jego stronie internetowej. Wiodącymi tematami jego twórczości są: biografie wielkich Polaków, losy Polaków za granicą, spotkania z Janem Pawłem II, a także historia miejsc i pomników charakterystycznych dla Krakowa. W dziennikach podróży i artykułach prasowych Grodeckiego znaleźć można również liczne relacje o tym, jak trudnym zadaniem było zdobywanie składników i przygotowanie pierogów w różnych częściach świata. Z analizy dzienników podróżniczych Grodeckiego wynika, że popularność pierogów wynika nie tylko z ich walorów estetycznych i smakowych.

Published: January 2024

Para enfrentar o desafio premente das alterações climáticas, há uma necessidade urgente de transições nos sistemas de energia, alimentação, transportes e outros. Entretanto, há certos grupos da população, como por exemplo trabalhadores de sectores que fazem uso intensivo de carbono, que ficam a perder no processo de transição pois são afectados de forma negativa, socialmente e economicamente. No seu cerne, a ideia de uma transição justa é que as transições devem considerar plenamente as necessidades destes grupos, incluindo a criação de novas oportunidades nas economias mais ecológicamente sustentáveis e com menor teor de carbono são construídas para substituir os sectores com elevada intensidade de carbono.

‘QUO VADIS, CORONA?’: METAPHORICAL FRAMING OF THE PANDEMIC IN DAILY PRESS
Authors: Begonja Helga , Prodanović Stankić Diana
Published: January 2024

The paper deals with the ways Croatian and Serbian daily newspapers wrote about the Covid-19 pandemic at its outbreak in 2020. The aim of the paper was to identify and describe metaphors in the selected corpus of texts in order to determine the metaphorical framing used in newspapers. This corpus-based research of media discourse was based on a qualitative bottom-up analysis that started from lexical metaphors found in the texts.
The results of this study suggest that a whole range of metaphorical mappings is used to frame the pandemic in the media in Croatian and Serbian. The results indicate that in both languages the same conventional metaphors were used. The pandemic was metaphorically conceptualized as an opponent, as some kind of disaster such as fire, or war. Different elements of the metaphorical mapping were made salient and foregrounded, depending on the text type. The obtained results are largely in line with previous research on using metaphors to describe the process of dealing with diseases.
ARTICULATING TRAUMA IN SHAUN TAN’S THE ARRIVAL
Authors: Luburić-Cvijanović Arijana
Published: January 2024

As a “trans” form of literature, according to Knowles, Peacock and Earle, the graphic novel offers a suitable medium for narrating transitional experiences. Shaun Tan’s The Arrival (2006) demonstrates this by telling a universal yet diverse story of migration and trauma, employing a dreamlike combination of realism and fantasy, and the immediacy of visual expression to represent precarious situations, states and emotions which are almost unrepresentable. A complex dialogue among images and pages, and the slow movement from panel to panel enable the reader to gradually understand the shifts inherent in migrant and traumatic experiences. As words would monopolise attention in Tan’s view and situate the narrative in a particular language, a conspicuous lack of words allows the narrative to communicate across cultures, simultaneously signalling the difficulty of verbally articulating trauma. Relying on studies of the graphic novel and trauma, this paper explores Tan’s narrative strategies for conveying trauma, and portraying migration as a shared and timeless experience. At the same time, the paper examines Tan’s promotion of cross-cultural and cross-species empathy and solidarity, thus avoiding what Stef Craps sees as one of the pitfalls of trauma theory.
DAS FANTASTISCHE UND DIE NARRATIVE KONSTRUKTION HEROISCHER MÄNNLICHKEIT IN FRIEDRICH DE LA MOTTE FOUQUÉS ERZÄHLUNG SOPHIE ARIELE
Authors: Marinkov Čolak Ivana
Published: January 2024

Tapfer ringende Ritterhelden sowie unheimlich-zauberhafte Wesen aus dem Reich des Fantastischen gehören zu den Kennzeichen des romantischen Weltenwurfs, den Friedrich de la Motte Fouqué in seinem Erzählwerk schildert. Die vorliegende Arbeit ist der Erforschung narrativer Inszenierung der Krise und Aufrechterhaltung heroischer Männlichkeit in Fouqués Erzählung Sophie Ariele (1825) gewidmet. Die narrative Entfaltung heroischer Männlichkeit im Rahmen der Erzählhandlung wird anhand des Modells der possible worlds theory von Marie-Laure Ryan untersucht, wobei besonderes Augenmerk der Funktionen gilt, die fantastische Elemente dabei ausüben. Die Merkmale der geschilderten Auffassung von heroischer Männlichkeit werden anschließend in Verbindung mit den zeittypischen Vorstellungen militärisch-heroischer Männlichkeit betrachtet. In dieser Erzählung erfolgt die Krisenüberwindung der heroischen Männlichkeit durch die innere Wandlung des Helden, bei der die fantastischen Figuren als Träger christlicher Leitsätze die entscheidende Rolle spielen. Fouqués Leitbild heroischer Männlichkeit weist wesentliche Elemente des verbreiteten militärischen Männlichkeitsentwurfs auf, wobei die Verbindung des kämpferischen Heldentums mit dem christlichen Ethos einen zentralen Stellenwert einnimmt.
MATIJA PETAR KATANČIĆ I PROUČAVANJE SREDNJOVEKOVNIH IZVORA
Authors: Стојковски Борис
Published: January 2024

U radu se razmatra način na koji je Matija Petar Katančić (1750-1825), pisac, pesnik, erudita i latinista proučavao srednjovekovne izvore. On je pripadao onim autorima koji su se bavili istorijom, jezicima i kulturom Južnih Slovena. Izjednačavao ih je sa Ilirima i smatrao je da su slovenski narodi autohtoni na Balkanskom poluostrvu. U tom kontekstu se bavio i proučavanjem srednjovekovnih izvora. U radu će biti razmotreno na koji je način Matija Petar Katančić izučavao srednjovekovne pisane izvore, posebno Jordanesa, Konstantina Porfirogenita, ali i još neke. Biće reči o njegovoj metodologiji, opštem poznavanju njemu dostupnih izdanja istorijskih izvora, te sveukupnom Katančićevom razumevanju srednjovekovne epohe. Samo pravilnim shvatanjem Katančićevih promišljanja o istorijskim izvorima moguće je shvatiti njegovo šire poimanje južnoslovenskog prostora, kao i naroda koji su živeli na njemu. Iako prvenstveno poznat kao pesnik, prevodilac Biblije i latinista, Matija Petar Katančić će u radu biti predstavljen kao proučavalac srednjovekovnih izvora, prvenstveno iz aspekta heuristike i hermeneutike.

The Russia–Ukraine confrontation in the Black Sea through the lens of the “grain deal”
Authors: Gudev P.
Published: January 2024

The launch of Russia’s special military operation in Ukraine was marked by the closure of a sufficiently large water area of the northwestern part of the Black Sea that Russia declared a “temporarily dangerous area” where it could not guarantee the safety of navigation. This affected the interests of both Ukraine and neutral states in the field of maritime trade. At the request of the UN Secretary-General, the Russian Federation formed a sea corridor for the safe transportation of the Ukrainian grain and other products in order to address the problem of hunger and food insecurity in most vulnerable states. This initiative was implemented until Russia pressed reasonable charges of complete violation of the peaceful spirit of the grain deal by Ukraine. Russia’s withdrawal from the “grain deal” marked the return to the regime of the temporarily dangerous area, which Ukraine and its foreign partners hastened to declare a full-fledged blockade. The formation of such a “closed” area for shipping and accusations of blockade require a legal analysis of the situation.
Vote for aid? How economic interaction with the United States affects countries’ voting patterns at the UN General Assembly
Authors: Davydov A.
Published: January 2024

The article investigates how the dynamics of economic aid from the United States and its trade and investment relations with a country affect the latter’s voting solidarity at the United Nations General Assembly. First, the approaches of Democrats and Republicans to financing the UN in connection with voting in the General Assembly are delineated. It is worth noting that Democrats tend to support multilateral institutions and policies, while Republicans have historically favored unilateral foreign policy. Still, both parties consistently prioritize allocating the U.S. funding for the United Nations to certain countries. The author uses data on financial flows directed toward multilateral institutions, along with other U.S. bilateral foreign aid, trade, and investment statistics, to explore whether economic interconnectivity affects the degree of the UN member states’ solidarity with the United States’ voting patterns at the General Assembly. It is concluded that economic relations with the United States do not significantly determine the increase in voting solidarity at the General Assembly. A group of 58 states is identified that, over a 25-year period (from 1996 to 2021), displayed a growing alignment with the United States in situations where it voted differently from the majority of other UN members. However, the increase in aid, trade, and investments from the United States to this group is primarily driven just by 13 major U.S. economic partners and aid recipients. Remarkably, the voting behavior of this select group of 13 states mirrors that of the remaining members of this focus group of 58 states.
BRICS Plus following the 2023 “expansion summit”
Authors: Lissovolik Y.
Published: January 2024

The 2023 BRICS summit unleashed a major expansion by the bloc, with five new members joining the BRICS core on January 1, 2024. However, while the geopolitical weight of the grouping has increased, its economic agenda remains vague. Some of the large emerging markets are having second thoughts about joining BRICS. After the 2023 presidential elections, Argentina declared that it would not become a member of BRICS. More fundamentally, the rift between India and China needs to be bridged in order for the bloc to gain greater prominence across the Global South. BRICS needs an ambitious trade liberalization agenda that would favor developing economies. This may become the basis for the evolution of the BRICS+ platform through multiple trajectories, including the “integration of integrations” track among regional integration blocs of which BRICS countries are members. In the longer term, the BRICS and BRICS+ formats may be complemented by a BRICS++ format, with participation of developed economies, regional blocs, and their development institutions.
Phobos e Eulabeia em Epicteto

Published: January 2024

Apresentaremos a concepção estoica sobre o medo para, a seguir, vermos seus desdobramentos na filosofia de Epicteto, mostrando que um dos fármacos estoicos contra o medo consiste em reavaliar as coisas indiferentes (que Epicteto reúne sob o título de coisas que não estão sob nosso encargo (ouk eph'hemin) de modo a lidar com elas não com medo (phobos), mas com cuidado (eulabeia), que, como uma espécie de eupatheia (boa emoção) é a contrapartida racional do medo.
Um olhar sobre nós: uma análise sobre a filosofia brasileira
Authors: Álvaro Marques Lúcio , Barbosa Metzker Giulia
Published: January 2024

O artigo busca discutir a filosofia do Brasil, seus desafios e possíveis soluções, a partir de uma abordagem interdisciplinar e histórica. O texto apresenta a análise da filosofia universitária brasileira, sua origem e atuação no século XXI, ressaltando que grande parte da produção acadêmica é pouco autêntica por ser uma exegese estrangeira. Além disso, é discutida a condição dos povos originários e dos negros escravizados, expondo como foram desumanizados pela colonização e suas condições de vida precárias e sua relação com a maneira que nos enxergamos. A partir disso, o artigo propõe a reflexão sobre a necessidade de pensar a filosofia brasileira a partir de sua situacionalidade e historicidade, superando o complexo de vira-lata e criando uma produção acadêmica autêntica e original, que reflita nossa identidade e individualidade, sem deixar de dialogar com outras tradições filosóficas.

Published: January 2024

The anaerobic dehydrogenation of dodecanol to dodecanal has been investigated in a continuous fixed bed reactor over a series of Cu-based catalysts with different supports (SiO2, Al2O3, ZnO and MgO). These catalysts have been systematically characterized by XRD, H2-TPR, NH3-TPD, CO2-TPD, XPS and N2-adsorption/desorption measurements. And the results indicate that the support has significant effect on the physicochemical properties of the catalysts and their catalytic performances, and Cu/SiO2 exhibited the highest catalytic activity in the dehydrogenation. Synergistic effect between Cu+ and Cu0 species has been observed, and proper ratio of Cu+/Cu0 is believed to be able to improve the catalytic performance of Cu-based catalysts. The surface acidity and basicity demonstrate significant effect on the distribution of the products and the selectivity to aldehyde. Under the optimized conditions, an 82.3% conversion of dodecanol with an excellent 98.9% selectivity toward dodecanal could be obtained. Moreover, the catalytic performance of Cu/SiO2 kept almost steady in 200 hours, indicating its good stability and application potential in the dehydrogenation process.
Three-Dimensional Runout Characterisation For Rotationally Symmetric Components

Published: January 2024

Rotationally symmetric components are ubiquitous to modern devices, and their precision manufacture is necessary to keep costs and manufacture time down, as well as reduce waste and possibly hazardous component failure. In this paper, a method of characterising the runout of rotationally symmetric machined parts in three-dimensions is presented, and evaluated using a virtual instrument simulation, enabling an accurate characterisation of the 3D surface deformation of a part from minimal surface information. For any 3D characterisation method to be widely adopted by the science, technology, engineering, and mathematics community, it must be fully compatible with previous methods and standards. As such, the proposed method produces a 3D runout vector based on four profile measurements. To evaluate the efficacy of the proposed runout method, a new technique for evaluating the errors of commonly used virtual instrument simulations has been developed. This evaluation technique produces a single valued quantification of the deviation of the simulation outputs compared to the input parameters, decoupled from the errors on the instrument itself.

DNA-templated silver nanoclusters (DNA/AgNCs) exhibited the outstanding optical characteristics for molecular diagnosis. Herein, we developed the degradation of template DNA- based fluorescent turn-off template ssDNA/AgNCs probe to construct the nucleic acids detection platform with exonuclease III (Exo III)-assisted cycle amplification. Our results demonstrated that the template DNA degradation of DNA/AgNCs dramatically decreased the fluorescent signal own to the morphological change. Inspired by this mechanism, target nucleic acids in our detection system could effectively hybridize with template DNA of ssDNA/AgNCs, and template DNA were cyclically degraded by Exo III-assisted cyclic degradation. The degradation of template ssDNA induced the changing of the morphology and the decreasing of fluorescent of AgNCs. Target DNA can be detected at low temperature (37 oC) without thermal cycles, showing a wide linear relationship from 0.4 to 200 nM. The limit of detection (LOD) was as low as 0.1 nM. The strategy offered a promising method to nucleic acids detection, which had excellent practicability in testing.

Published: January 2024

Background: Wildfires, in recent years have caused devastating destructions in many parts of the world due to extreme weather conditions. Wildfire trend in Tsavo Conservation Area in Kenya is not well understood and published articles on wildfires in the region are limited. Our study aimed at establishing the relationship between weather and Wildfire pattern in Tsavo Conservation Area, which is in southeastern side of Kenya. Such information could be useful in predicting the likelihood of Wildfire occurrence. Hence making Wildfire management easier and sustainable.
Results: We obtained secondary data for Wildfire occurrence and climatic factors to establish: Relationship between Wildfires and weather patterns, Wildfire seasons, Wildfire predictive models and Wildfire indicators combination matrix model. Our study obtained remote sensed Wildfires data for 19-year period from 2002 – 2020 from National Aeronautical and Space Administration website. We also obtained weather data for the same period from the Kenya Meteorological Department. The data provided by Kenya Meteorological Department included temperature, rainfall, wind speed, and humidity. Our study used Generalized Additive Model with poison distribution and Spearman Correlation to analyze the relationship between Wildfire occurrence and weather variables. The year 2020 recorded the highest number of Wildfire of 481 during the study period. We established the wildfire season for the Tsavo Conservation Area to be from June to October. September recorded the highest average number of Wildfires of 690 within the 19-year period. Humidity is the best predictor for wildfires in Tsavo Conservation Area. Our study also came up with a Matrix Model that could be used to identify months of the year that are likely to experience high Wildfire occurrence.
Conclusion: The findings would be very useful in Wildfire management as they provide new knowledge on Wildfire occurrences in the area. Humidity factors being the best in predicting Wildfires and June-October being the Wildfire season for Tsavo Conservation Area forms such knowledge. The Matrix Model provide the basis for further studies in Wildfire forecast.

Published: January 2024

Hybrid nanocomposites, comprising epoxidized natural rubber (ENR) filled with graphene (GP) and carbon nanotubes (CNTs), were prepared via the melt mixing technique. TEM imaging confirmed the development of three-dimensional filler networks, facilitated by the π-π interaction between sp2-hybridized carbon atoms in graphene and carbon nanotubes, alongside Van der Waals forces. Moreover, a notable interaction between polar functional groups on the nanofiller surfaces and the ENR molecules emerged as a significant factor in enhancing properties. This was evidenced by the rise in bound rubber content with increasing CNT loading, amplifying reinforcing efficiency through the establishment of bridge links among rubber chains and filler networks. Temperature scanning stress relaxation (TSSR) results unveiled escalating relaxation forces, moduli, and crosslink density upon nanofiller incorporation and with increasing CNT loading. DMA results indicate elevated storage modulus and glass transition temperature (Tg), coupled with reduced coefficient of reinforcement (C-factor), indicative of an increased degree of reinforcement.

Delivery of active protein especially enzyme is one of the major therapeutic challenge. Replacing or substituted invalid/improper acting protein offer fast and effective treatment of disease. Herein, we describe the synthesis and properties of biotinylated peptidomimetics consisting of oxoacid - modified 2,3, L- diaminopropionic acid residues with guanidine groups on its side chains. Electrophoretic analysis showed that the obtained compounds interact with FITC-labeled streptavidin or a streptavidin–β-galactosidase hybrid in an efficient manner. Complexes formed by the abovementioned molecules are able to cross the cell membranes of cancer or healthy cells and show promising compatibility with live cells. Analysis of β-galactosidase activity inside the cells revealed surprisingly high levels of active enzyme in complex-treated cells compared to controls. This observation was confirmed by immunochemical studies in which the presence of β-galactosidase was detected in the membrane and vesicles of the cells.
