Respecto de los temas social, económico, político e internacional, el de la educación nacional en los años inmediatos anteriores a la guerra, no ofrece una vasta bibliografía que sistematice su desarrollo o divulgue su conocimiento. Pocos son los estudios que lo abordan y escasas las fuentes que lo sustentan 1, En el marco de estas limitaciones bibliográficas, tres son las fuentes (publicadas todas ellas por esos años) que podemos citar como indispensábies , para reconstruir su compleja realidad: LiJ educación popular en el Perú (Santiago de Chile, 1872) del polifacético Félix Cipriano Coronel Zegarra. Constituye una excelente "radiografía" del estado de · la instrucción primaria del Perú de entonces. Además, notable por los lineamientos que con asombrosa precisión su autor señaló para el mejoramiento de la educación a este nivel: rentas, infraestructura, preparación docente, métodos, material didáctico, equipos dé enseñanza, etc.
La geografía moderna en el pensamiento de Richard Hartshorne

Published: May 2023

El análisis de la caracterización de la geografía, presentada por el profesor Hartshome, permite recordar y precisar los fundamentos metodológicos de la ciencia geográfica moderna. Un tema de estudio tan amplio, como es el de la revisión de las bases metodológicas de una ciencia, en este caso la geografía, obliga a un desarrollo secuendado de tópicos, tales como, el contenido u objeto de estudio de la ciencia, su localización dentro del conocimiento científico, problemas de simplificación del contenido, y métodos de investigación, entre otros.

Notas sobre la problemática de la educación y el empleo en el Perú
Authors: Fernández Hernán
Published: May 2023

El rápido crecimiento del sistema educativo, la notable migración campo-ciudad y los efectos en el empleo producto de la crisis económica que vive el país han generado un cuadro dramático y completo. Las generaciones nuevas que se incorporan al mercado de trabajo, pugnan (particularmente en las ciudades) en condiciones mucho más dif íciles que los precedentes. Debido a la sobreoferta de mano de obra educada, los requerimientos educativos son- artificialmente altos, lo que lleva a los jóvenes a la búsqueda de la certificación dada en las múltiples formas de la calificación profesional extraordinaria, para mejorar sus niveles de competitividad. Se está produciendo entonces la desvalorización de la educación.
Estética del Trabajo. Una alternativa a la vanguardia
Authors: Vélez Julio
Published: May 2023

Un simple corte sincrónico en los años del período de entreguerras nos muestra tal multiplicidad de manifiestos considerados como "vanguardia" por las teorías tradicionales, que resulta prácticamente imposible lograr una simbiosis entre ellos. Si por demás procuramos un análisis pragmático, los textos, que en multitud de ocasiones no tienen nada que ver con los manifiestos bajo los que se agrupan, son tan diversos, que la única conclusión aceptable sería aquella que afirmara la existencia de un corpus textual tan antagónico, que los rasgos de parecido entre ellos es prácticamente inexistente.
Ideas estéticas sobre Vallejo
Authors: Falla Barreda Ricardo
Published: May 2023

En primer lugar, agradezco al poeta y profesor de esta universidad, Ricardo González Vigil, la invitación a participar en este conversatorio sobre César Vallejo, cuyo centenario de su nacimiento estamos conmemorando. Y, en segundo lugar, pido disculpas ante todo, porque en realidad no me dispongo a sostener puntos de vista en calidad de filósofo o especialista en estética, sino de escritor y lector de poesía. Estas son, pues, las dos modalidades con que me acerco a César Vallejo. Debo confesar, no obstante, que por esta senda me he topado con grandes dificultades, especialmente porque se trata de un poeta de riquísimas implicancias. Por ello, en torno a "ideas estéticas sobre Vallejo" daré algunos alcances que mi calidad de escritor y lector de poesía me permiten ofrecer.
La concepción religiosa de Vallejo
Authors: Gutiérrez Gustavo
Published: May 2023

También yo, como los que me han precedido en el uso de la palabra, quisiera agradecer la invitación de Ricardo González Vigil a participar en este Coloquio con algunas reflexiones sobre el tema de Dios en Vallejo. Tenemos una vieja amistad a pesar de su juventud (la parte vieja la pongo yo ... ). Y él sabe igualmente que no soy un especialista en Vallejo. Mi terreno es otro, pero no es posible, creo, no aceptar, siendo peruano, latinoamericano y simplemente un ser humano, los desafíos que nos vienen de una poesía como la de Vallejo.

Relevance of batik art therapy in emotional regulation teaching method
Authors: Jais Noraziyanah Md , Min Low Hui , Hamzah Aswati
Published: May 2023

In the school setting, intervention for children with special educational needs typically focuses on reading, writing, and counting skills, with less attention paid to the aspects of emotional regulation. Emotional regulation and management skills are essential for students with special education needs .  This article, therefore, aims to identify and discuss the need for exposure and the development of an emotional regulation teaching method, that utilizes batik art therapy as a pedagogical strategy. For a need’s assessment, an open-ended survey was conducted with 35 special education teachers identified using the purposeful sampling technique. The research used thematic analysis, which showed the need to develop emotional regulation teaching methods and a strong teachers’ interest in attending formal emotional regulation  training programs. At the same time, the relevance of batik art therapy as a teaching method for emotional regulation was strongly supported by the special education teachers involved. The research findings pointed to the need to develop an emotional regulation teaching method using the batik art therapy approach.

La competitividad de las exportaciones del sector químico mexicano en los Estados Unidos de América y la Unión Europea, 1994-2015
Authors: Vázquez López Raúl
Published: May 2023

Este artículo tiene por objetivo analizar la evolución de la competitividad de las exportaciones del sector químico mexicano en los mercados de Estados Unidos (E.U.) y la Unión Europea (U.E.), por categoría de productos, en el periodo 1994-2015. Para ello, se toman como referencia las transformaciones estructurales ocurridas en los patrones de especialización de sus competidores en cada mercado. Se confirma la hipótesis de que el cambio en la composición de las exportaciones no se da en un sentido dinámico, porque no se produce hacia los productos con una participación creciente en los mercados mundiales ni tampoco se registra en favor de la fabricación y venta de mercancías con mayores grados de sofisticación. El hallazgo resulta de la aplicación de una técnica diferencial estructural dinámica que permite descomponer las variaciones en el tiempo de los diferenciales entre las exportaciones de México y las de sus principales competidores en tres efectos (estructural, competitivo e interactivo).
Editorial. Luchas campesinas en perspectivas territoriales latinoamericanas
Authors: Mejía Ayala Wladimir
Published: May 2023

La tendencia política actual en Colombia y Latinoamérica, la cual apunta más a la izquierda que a la derecha, aviva inevitables tensiones, así como expectativas y esperanzas, sobre todo en aquellos que en muy pocas ocasiones han sido escuchados, como los campesinos latinoamericanos y, en particular, los campesinos colombianos. A pesar de los altos costos de producción, una alta dependencia del sector de los fertilizantes, plaguicidas y otros materiales, las fluctuaciones del mercado ylas embestidas del cambio climático, la agricultura campesina en este país provee, según el Ministerio de Agricultura y Desarrollo Rural, el 70% del total de los alimentos que consumimos hoy. Adicionalmente, es la actividad que más empleos rurales genera y cumple, al mismo tiempo, un innegable e invaluable rol en la conservación de la agrobiodiversidad, la oferta de servicios ambientales y la preservación de espacios y ecosistemas frágiles.
Significados parciales de la derivada en libros universitarios en la formación de ingenieros
Authors: Larios Víctor , Jiménez Angélica
Published: May 2023

La relevancia del cálculo en la formación de ingenieros ha generado interés en el estudio de su aprendizaje y en la construcción de significados asociados a los objetos que lo componen. Los significados que circulan en los cursos están influidos por recursos y materiales de consulta que los profesores aprovechan, como los libros de texto. Por ello, es pertinente identificar cuáles son los significados que se promueven en esos materiales. Este trabajo presenta un análisis de los significados que algunos libros usados en la formación de ingenieros promueven sobre el concepto de derivada, con base en el enfoque ontosemiótico del conocimiento matemático. Las observaciones se contrastaron con los significados parciales que la derivada ha tenido a lo largo de su desarrollo histórico. Se observó que se privilegia el significado parcial, que corresponde a la última etapa de su desarrollo histórico, con lo cual se pretende lograr una generalización en su estudio, pero que se aleja de un acercamiento intuitivo que podría servir para el aprendizaje de los alumnos.
Vulnerability Analysis of Rectorate Building of UIN Mataram against Earthquakes Based on Microtremor Data
Authors: Ilham Ilham
Published: May 2023

Lombok Earthquake in 2018 caused several damages to buildings, including buildings at UIN Mataram. Therefore, it is necessary to carry out mitigation efforts to reduce losses caused by the earthquake. This study aims to analyze the level of vulnerability of the Rectorate Building of UIN Mataram based on microtremor data. Microtremor signal recording was performed using a 3-component Digital Portable Seismograph, type TDL 303S with a Feedback Short Period Seismometer sensor type DS-4A, GPS, and Laptop. The recording time for each measurement point was 40 minutes with a sampling rate of 100 Hz. The natural frequency of the Rectorate Building of UIN Mataram is 4.15 Hz for the N-S component, and 4.05 Hz for the E-W component. The natural frequency of the Rectorate Building is following the SNI (2002) standard. The resonance index value of the Rectorate Building with the surrounding land is in a low category so that the Rectorate Building is classified as safe against earthquakes. The highest building Vulnerability Index is on the 3rd floor of the Rectorate building, especially in the south wing. For disaster mitigation, the 3rd floor can be converted as a room with minimal staff to reduce the possibility of casualties in the event of an earthquake in the future.
Políticas de Educação Especial no Brasil: ameaças, contradições e descontinuidades
Authors: Santos Geandra Claudia Silva , Neta Adelaide de Sousa Oliveira , Anache Alexandra Ayach
Published: May 2023

Mudanças na cena política brasileira tem gerado um contexto de contrarreformas resultantes da lógica neoliberal, com tendência ultraconservadora, que atingem os direitos sociais conquistados, com implicações importantes nas políticas educacionais e sob a influência dos organismos internacionais. A Política Nacional de Educação Especial na Perspectiva da Educação Inclusiva (PNEEPEI) de 2008, nesse contexto, sofre ameaça de revogação, por meio do Decreto 10.502/2020 do Ministério da Educação. O artigo objetiva analisar mudanças propostas na revisão da PNEEPEI, por meio do decreto em correlação com documentos internacionais e com as políticas ultraconservadoras. Trata-se de uma pesquisa qualitativa, do tipo documental. Os resultados apontam a relevância da PNEEPEI no avanço da educação inclusiva. O decreto, inspirado pela Declaração de Incheon, visa alterar a organização da Educação Especial que representa riscos à manutenção da perspectiva inclusiva, ao defender, dentre outros aspectos, a descaracterização do Atendimento Educacional Especializado, o estímulo à matrícula em espaços especializados; ampliação da participação do setor privado; responsabilização de famílias na decisão sobre matrícula. Conclui-se que a inclusão é uma construção complexa e contínua e não ocorre só alterando a organização da Educação Especial, mas alterando a estrutura excludente da educação geral, para garantir acesso e aprendizagem.

Published: May 2023

Este artigo objetiva analisar as orientações políticas do Banco Mundial (BM) e da UNESCO para a educação especial e a educação inclusiva, na educação básica, para o Brasil, a partir do contexto da crise mundial de 2008 até a crise decorrente da pandemia da covid-19. Trata-se de uma análise documental e qualitativa ancorada no materialismo histórico e dialético e na compreensão de que os documentos de políticas educacionais são produtos e produtores da realidade e expressam os interesses de grupos sociais em disputas. Examina as crises de 2008 e da covid-19 como integrantes da crise estrutural do capital e, portanto, como agravantes de tal crise. Concebe as orientações do BM e da UNESCO para a educação especial e inclusiva, específicas ou não para o Brasil, como parte de uma agenda global da educação, coordenada pelos organismos internacionais. Essa agenda dissemina um discurso de educação inclusiva dos grupos vulneráveis, como o público-alvo da educação especial, cuja concepção de inclusão se restringe à formação de capital humano para amenizar as desigualdades e os conflitos decorrentes das crises e reproduzir o processo de acumulação do capital.

Free lipoproteins from Bifidobacterium longum alleviate osteoarthritis through modulation of the gut microbiome
Authors: Sane Famara , Piva Frank , Romond Marie-Bénédicte
Published: May 2023

Aim: The “gut-joint” axis is suspected to be involved in the pathophysiology of osteoarthritis (OA). The present study aims at investigating the potential of lipoproteins (Lpps) secreted by Bifidobacterium longum to alleviate OA progression in the rat. Methods: Experimental OA was induced in rats harbouring Schaedler Flora maintained in SPF conditions. Two weeks post-injection, 20 rats were randomized to water (n = 10) or 0.3 mg/L Lpps solution (n = 10). Weight and food intake were monitored for 6 weeks. At sacrifice, joints were scored using macroscopic and histological criteria. Serum LPS, Schaedler flora as well as selected intestinal bacteria were analyzed. Results: Lpps intake prevents OA progression. The protected rats showed a significant increase in lactobacilli along the intestine as well as in Mucispirillum schaedleri in the colon and a significant decrease in Parabacteroides goldsteini and Akkermansia in caecum and colon, respectively. There was no significant difference in serum lipopolysaccharide or bacteria translocating in Peyer's patches. Labelled Lpps were not detected in bone marrow of the OA joint. The principal component analysis points out that OA prevention is primarily associated with bacteria involved in the tryptophane degradation pathway and SCFA formation. Conclusion: In rats deprived of bifidobacteria, intake of B.longum Lpps prevented OA development and modulated the intestinal microbiome with a possible impact on the bacterial end-products. The link between Lpps and the gut microbial metabolome warrants further investigation.

Authors: Canales Dinko , Moraga Roberto
Published: May 2023

The search for growth and sustainability in any organization largely depends on its ability to carry out digital transformation and agility processes. These processes are essential to adapt to an increasingly changing and competitive business environment, allowing companies to be more efficient and effective in creating an unbreakable bond with their customers. This manuscript addresses the importance of detecting and eliminating anti-patterns in organizational culture for a successful digital and agile transformation. During the early stages of the transformation process, prejudices and paradigms rooted in the organization can become an obstacle to change. The goal of this writing is to offer a practical guide for leaders and teams in organizations seeking successful cultural transformation. Effective strategies are proposed to overcome the challenges faced by organizations during this early stage. In summary, the key steps to be followed in the initial stages of digital transformation with agility are described, including the importance of establishing strong leadership, defining a clear vision and scope of the transformational process, among others. A set of recommendations will be provided to overcome recurring anti-patterns, such as lack of stakeholder participation and commitment, lack of proper planning, and confusion of roles and responsibilities.

: The objective of this study was to obtain different dry matter contents and proportions of mel-on plant biomass for silage making. A completely randomized design was adopted with a facto-rial scheme (3 x 2) in four replications. The first factor corresponded to three mixtures of melon biomass on as fed basis (AF) of plant (branch + leaf) and fruit (harvested melon) as follows: 100% plant, 90% plant + 10% fruit, and 100% fruit. The other factor corresponded to the ensiled materi-al with fresh and dehydrated melon plant biomass (40% DM) which was dried in the field, after harvest. Silages with partial dehydration of the biomass available after fruit harvest with 0% and 10% fruit showed the greatest DM values: 297 and 293 g/kg DM, respectively. Silages with 0, 100 and 10% fruit showed medium LAB populations: 5.79, 5.14 and 4.58 logs CFU/g, respectively. Higher concentrations of acetic acid contents were observed in silages with 0 and 10% fresh fruit, which were 14.9 and 14.1 g/kg DM, respectively. Silages with 0% and 100% of dehydrated fruit showed better results for the indicators of good-quality silage. Dehydration improves the fer-mentative profile and quality of the melon silage.

Authors: Verma Himanshu , Chauhan Naveen , Awasthi Lalit Kumar , A. Ramalingam , Kumar Ajit , Choi Bong Jun
Published: May 2023

The Internet of Healthcare Things (IoHT) is an essential IoT domain that encompasses the necessary capabilities to transform the current healthcare system. IoHT generates, transfers, manages, stores, and processes highly confidential medical data and sensitive personal information. Thus, IoHT is a critical application from a security perspective and is most favorably targeted by attackers. Several security-breaching attempts can be carried out due to the vulnerabilities of the IoHT that put classified data at constant risk. Henceforth, this work aims to inspect the performance of 6LoWPAN-RPL-based `Patient-Centric IoHT’ in the presence of malicious intruders conducting blackhole, rank, and DoDAG attacks in both normal and emergency operational modes of the mentioned resource-constraint network. PC-IoHT is simulated on the Cooja simulator and Contiki-OS for each attack with two and four intruders (out of 10 motes) for both operation modes. Several performance evaluation parameters are used to assess the overall performance of the considered PC-IoHT. The attacks’ impact on PC-IoHT is analyzed by comparing blackhole, rank, and DoDAG attacks with the no-attack scenario.

Published: May 2023

As a result of scientific technological advancements in medical diagnostics, treatment modalities of non-communicable and communicable diseases, and palliative care approaches, the life expectancy of women is soaring than men across the globe, due to the longer telomere length and other protective factors. The main symptoms of menopause broadly be divided into psychological somatovegetative and urogenital. Neglected menopausal symptoms can lead to debilitating comorbidities which may end up in mortalities. Fortunately, modern treatment and therapeutic formalities based on pharmaceutical preparations, as well as lifestyle- modifications have provided long-lasting relief for the pre-menopausal woman. This can be done as per her preference if she is knowledgeable, resourceful, and cheerful. Menarchae is the “ alpha” and menopause is the “omega” phase in the reproductive lifecycle of any woman. Reproductive health is essentially an integral part of women’s health. In this 4th industial revolution era information technology and digital science go hand in hand to improve the quality of life of populations across the globe irrespective of their educational and professional status. Health literacy among disadvantageous sub populations increased. Positive attitudes, perception and evidence-informed knowledge on adolesecent girls about not only ‘period pains’ but menopausal symptoms as an inevitable phase in a woman’s reproductive health may make a better sense at the dawn of evidence based medicine even in a low middle income country like Sri Lanka. Hence, this timely communication strengthens by, Do not fear when menopause is near: The Importance of a Preparatory Time and Space to face the consequences of Menopaus. How to forget the fact that alpha and the omega are inevitable phases in woman’s reproductive health trajectory. Moreover, the importance of a preparatory time and space well in advance preferably in peri-menopausal time to prevent and control the inevitable health consequences. Moreover, to invest in menopause for a brighter future in the modern personalized medicine era based on global scientific evidence.
Luck Clustering in Sports: Applications and Implications for Performance and Strategy
Authors: Farshi Esmaeil
Published: May 2023

The notion of luck clustering has gained traction in recent years due to its potential influence on performance and decision-making across a range of domains. This study concentrates on the application of luck clustering in sports, with an emphasis on its consequences for performance metrics and strategic decision-making. We employ time series analysis to investigate the presence of luck clustering in sports data, such as win-loss records, scoring, and player rankings, while considering the role of the Principle of Luck Conservation in the observed clustering patterns. Our findings provide evidence of luck clustering in sports, implying that periods of high luck tend to be followed by more high luck events, and vice versa for low luck events. These insights carry significant implications for coaches, players, and teams, who can utilize the understanding of luck clustering to develop more effective strategies, manage resources efficiently, and ultimately enhance their performance. By enriching our comprehension of luck's nature and its effects on sports outcomes, this study contributes valuable knowledge for practitioners and researchers in sports analytics and performance management.

Published: May 2023

Nowadays, the Internet of Things (IoT) concept plays a pivotal role in society and brings new capabilities to different industries. The number IoT solutions in areas such as transportation and healthcare is increasing and new services are under development. In the last decade, society has experienced a drastic increase in IoT connections. In fact, IoT connections will increase in the next few years across different areas. Conversely, despite these benefits, several challenges still need to be faced to enable efficient and secure operations (e.g., interoperability, security, standards, and server technologies). Furthermore, although efforts have been made to produce datasets composed of attacks against IoT devices, several possible attacks are not considered. Most existing efforts do not consider an extensive network topology with real IoT devices. The main goal of this research is to propose a novel and extensive IoT attack dataset to foster the development of security analytics applications in real IoT operations. To accomplish this, 33 attacks are executed in an IoT topology composed of 105 devices. These attacks are classified into seven categories, namely DDoS, DoS, Recon, Web-based, Brute Force, Spoofing, and Mirai. Finally, all attacks are executed by malicious IoT devices targeting other IoT devices.

Published: May 2023

Many ecosystems are being severely degraded, leading the United Nations to deem 2021-2030 as the Decade on Ecosystem Restoration. To be successful, this effort requires robust monitoring tools to assess land reclamation practices. Our study aimed to evaluate the quality of recovery efforts in mined areas by developing a Recovery Quality Index (RQI) based on soil and vegetation indicators. Using the heavily mined Iron Quadrangle region of Brazil as an example, we selected four local, undisturbed reference areas as restoration goals: Atlantic Forest (AF); ferruginous rupestrian grassland with dense vegetation (FRGD); ferruginous rupestrian grassland with sparse vegetation (FRGS); and quartzite rupestrian grassland (QRG). We also selected four areas that were directly or indirectly affected by mining, including an environmental compensation area set aside 5 years prior to the study (COMP-5), two sterile piles that had undergone recovery for 15 and 20 years (SP-20 and SP-15), and a cave area with 15 years of recovery (CAVE-15). The four recovery areas were grouped together with each individual reference area (making four combinations of sites), and measurements of 2 vegetation parameters and 34 soil attributes were used in a Principal Component Analysis (PCA) for each grouping. We determined the RQI for each group by summing weighted PCA scores for responsive indicators. Vegetative parameters had the lowest RQI weights in all four groups. Soil physical indicators tended to be the most important, except in AF, where chemical indicators were most relevant. RQI values were also lowest when AF was used as the reference, showing that the forest was a unique ecosystem, and the CAVE-15 site had lower RQI scores than the other restored sites, indicating the high degree of disturbance that occurred in that low-lying area. The SP-20 site tended to have higher RQI values than the SP-15, and similar values to the less disturbed COMP-5 areas, potentially indicating greater recovery of native soil properties during the longer recovery period. This RQI-based approach has excellent potential for robust assessment of the recovery of areas degraded by mining and can support decision-making during monitoring.

Published: May 2023

This paper applies a new artificial intelligence architecture, the Temporal Fusion Transformer (TFT), for the joint GDP forecasting of 25 OECD countries at different time horizons. This new attention-based architecture offers significant advantages over other deep learning methods. First, results are interpretable since the impact of each explanatory variable on each forecast can be calculated. Second, it allows to visualize persistent temporal patterns and to identify significant events and different regimes. Third, it provides quantile regressions and permits to train the model on multiple time series from different distributions. Results suggest that TFTs outperform regression models, especially in periods of turbulence such as the COVID-19 shock. Interesting economic interpretations are obtained depending on whether the country is domestic demand-led or export-led growth. In essence, TFT is revealed as a new tool that artificial intelligence provides to economists and policy makers, with enormous prospects for the future.

Published: May 2023

This article presents a low-cost and flexible solution for acoustic startle response (ASR) tests that can be used in any laboratory with CED Power1401 or a similar Spike2-based interface. ASR is a reflexive response to an unexpected, loud acoustic stimulus, and prepulse inhibition (PPI) is a phenomenon in which the startle response is reduced when preceded by a weak prestimulus of the same modality. Measuring PPI is important because changes in PPI have been observed in patients with various psychiatric and neurological disorders. Commercial ASR testing systems are expensive, and their closed source code affects their transparency and result reproducibility. The proposed setup is easy to install and use, and simultaneous recording of ASR and brain activity (electrocorticogram or intracerebral local field potential) is possible. The Spike2 script is customizable and supports a wide range of PPI protocols. The article presents data obtained in female rats, both wild-type (WT) and dopamine transporter knockout (DAT-KO), showing the same tendency as the data obtained in males, with ASR on single pulse higher than ASR on prepulse+pulse, and PPI reduced in DAT-KO rats compared to WT.

Infectious diabetic wounds can result in severe injuries or even death. Biocompatible wound dressings offer one of the best ways to treat these wounds, but creating a dressing with suitable hydrophilicity and biodegradation rate can be challenging. To address this issue, we used the electrospinning method to create a wound dressing composed of poly(glycerol sebacate) (PGS) and gelatin (Gel). We dissolved the PGS and Gel in acetic acid (75 v/v%) and added EDC/NHS solution as a crosslinking agent. Our measurements revealed that the scaffolds' fiber diameter ranged from 180.2 to 370.6 nm, and all the scaffolds had porosity percentages above 70%, making them suitable for wound healing applications. Additionally, we observed a significant decrease (p < 0.05) in the contact angle from 110.8° ± 4.3° for PGS to 54.9° ± 2.1° for PGS/Gel scaffolds, indicating an improvement in hydrophilicity of the blend scaffold. Furthermore, our cell viability evaluations demonstrated a significant increase (p < 0.05) in cultured cell growth and proliferation on the scaffolds during the culture time. Our findings suggest that the PGS/Gel scaffold has potential for wound healing applications.

Published: May 2023

Integrating numerous renewable resources has been extensively researched and studied to create a dependable energy system. This study investigated the best techno-economical hybrid energy system configuration while using hydrogen energy to keep the system's energy balanced. Additionally, this study aims to determine the best hybrid system configuration for the location under investigation. A novel technique of DBM (Deterministic Balanced Method) was introduced to determine the total annual energy output for the project's lifetime. This approach is used to contrast the outcomes of other HOMER software tools. Then, using HOMER, it is possible to confirm the sizing optimization results for the suggested method by comparing the power ratings and yearly energy output. A detailed comparison between our proposed method and HOMER Pro has been conducted for validation and verification. Our method has been rigorously tested in various hybrid off-grid energy systems, ensuring its applicability and reliability across different scenarios and configurations. The results of our study indicate a high degree of similarity between the proposed approach and HOMER pro for computing annual energy power for the studied energy systems. Specifically, our analysis revealed that the difference between the approaches was within a range of 5%, indicating a high level of consistency and reliability in our method. These findings suggest that our approach can be confidently applied to determine the appropriate size of hybrid energy systems accurately. Overall, our study provides valuable insights into the development of effective sizing methodologies for hybrid energy systems. After considering the amount of solar radiation and wind speed gathered by global weather data platforms like NASA and METEONORM, this paper has also included a real case study of the Cairo International Airport's hybrid renewable energy production systems. To guarantee the viability of this study, the system design was founded on an actual load that was researched and simulated. A cluster of distributed networks was finally proposed to use the excess energy and enable energy conversion processes to be used in industry and transportation applications.

A review of pesticide residues detected in shrimp species of the Mexican Pacific and Gulf of Mexico coasts is presented. Most studies focus on monitoring organochlorine (OC) and organophosphate (OP) pesticides. The evaluated areas are mainly located in the northwestern zone of Mexico. Studies analyzing pesticides levels in shrimp of Mexico correspond to commercially important species, such as: Penaeus vannamei, Penaeus stylirostris, Farfantepenaeus duorarum, and Trachypenaeus similis pacificus. Extraction methods (sample preparation, extraction technique, solvent, and clean-up procedures) are presented, as well as chromatography and detector type used to quantify the analytes in the shrimp samples from the different ecosystems evaluated. Given that there is an under-evaluation of pesticides residues presence, there was a greater contribution of studies directed to geographical areas in the northwest of the country, with a monitoring gap in the Gulf of Mexico, as well as in the southern zone, considering that there are states that are among the main shrimp-producing entities. Hence, it is necessary to carry out recent evaluations, since the most current information is 17 years out of date, so presented data may not be a reflection of the current situation in the country.

Published: May 2023

This study aims to analyze the interconnection between the concepts of digital economy and sustainability. These concepts have become popular due to awareness of climate change and increased development and adoption of technologies. Researchers, business leaders and policymakers are exploring the many ways digital technologies can be used to address sustainability issues. Using a systematic literature review with a bibliometric analysis, we examined a sample of 92 studies indexed in SCOPUS to identify research activity on this topic through April 2023. We found that 2022 had the highest number of peer-reviewed papers on the subject, with 31 publications. During the research, we also identified multiple opportunities for this interconnection, such as developing renewable energy and sustainable technological solutions, smart cities and sustainable urbanization, and sustainable consumption. These opportunities enabled by digital technologies allow companies to adopt sustainable business strategies and develop sustainable products. Despite these opportunities, the digital economy presents several challenges that can hinder efforts to achieve sustainability goals, such as increased e-waste, high energy consumption and rising carbon emissions, digital divide, job insecurity, growing monopolies, and data protection. These issues must be addressed to enable optimal use of the opportunities presented in the digital economy to promote sustainability.
