Published: May 2023

The main objective of this paper is to investigate the mechanism of formation and evolution of a river mouth island in front of Cua Dai - a mouth of Vu Gia - Thu Bon river system. The combination of coastal morphodynamic analysis with remote sensing, mapping and GIS methods has shown that the formation and evolution of this island depends on a long-term and complex interaction between the dynamics of the Vu Gia - Thu Bon river system and the coastal littoral, including the Cu Lao Cham archipelago. This process has three stages: i) The formation of river mouth bar; ii) The formation of island in front of the river mouth; and iii) The deformation of island morphology in front of the river mouth. The materials that formed Cua Dai island are not only carried out by the Vu Gia - Thu Bon river system, but also from longshore sediment due to coastal and estuary erosion, mainly from the northern part of Cua Dai. Based on the interaction between material factors (river and longshore sediments) and energy (sea and river dynamics), the evolution of the river mouth bar in front of the Cua Dai island may follow one of two trends: i) The Cua Dai island will gradually move closer to the north shore of Cua Dai, erodes over time, then disappear, assuming no major flood in the Vu Gia - Thu Bon river system and wave and flow regimes are as normal as in the period before 2016; or ii) The Cua Dai island will continue to exist and change if there is an increase in climate change, especially extreme events such as storms, floods, and sea level rise.

Published: May 2023

Introducción.  La enseñanza es una profesión emocionalmente desafiante, que a veces resulta en altos niveles de estrés, agotamiento y desgaste de los maestros. A menudo se ha afirmado que ciertas competencias emocionales como la inteligencia emocional pueden reducir los sentimientos de agotamiento de los profesores.
 
Método.  Se analiza, de forma descriptiva y correlacional las dimensiones de la inteligencia emocional (evaluación de las propias emociones, evaluación de las emociones de los demás, regulación de las emociones, uso de las emociones) y los factores del burnout (agotamiento emocional, despersonalización y baja realización personal). Se aplicó como técnica estadística el análisis de red que representa conjuntamente las correlaciones parciales de todas las variables. Se tuvo en cuenta una muestra de 244 maestros de Educación Primaria (51.6% mujeres) y (48.4% hombres) con edades entre 25 a 65 años (M = 45.68, DT = 8.43) que laboraban en trece instituciones educativas ubicadas en áreas urbanas y semi-urbanas de la ciudad metropolitana de Lima, Perú.
Resultados. Las mayores conexiones positivas de red se encontraron entre el agotamiento emocional, la despersonalización, y la baja realización personal, así como entre la comprensión de las emociones de los demás y el uso de las emociones, ambas medidas fueron más influyentes en los demás patrones asociativos de red. Mientras la mayor asociación negativa se registró entre la baja realización personal y la comprensión de las propias emociones. Asimismo, se demostró la estabilidad de las medidas de centralidad de fuerza y la precisión de los nodos o variables de la red.
Discusión y conclusiones. Se puede concluir en la presente investigación una mayor importancia de los componentes de evaluación de las emociones de los demás y uso de las emociones, que refuerzan directa e indirectamente las conexiones de la dinámica de la Inteligencia emocional y reducen los niveles del burnout, especialmente afianzan un menor grado de agotamiento emocional, el cual fue el factor de mayor puntuación. La consideración de tales competencias emocionales es determinante para una mejor eficacia en la intervención y prevención del burnout en el profesorado. Asimismo, la medida de despersonalización es la variable nexo que influye en la manifestación de mayores niveles de sentimientos de agotamiento emocional y baja realización personal.

Published: May 2023

Introducción. La discusión en torno al logro académico en el contexto de la educación a distancia ha planteado la necesidad de desarrollar estudios que permitan identificar las variables que mejor lo predicen. El objetivo de esta investigación fue analizar el ajuste de un modelo de ecuaciones estructurales que presupone que las variables sociodemográficas, los rasgos de personalidad, la motivación y los estilos de aprendizaje como predictores del logro académico.
Método. Participaron voluntariamente 354 estudiantes de psicología a distancia de una universidad privada de Bogotá D.C., quienes fueron reclutados a partir de un muestreo probabilístico estratificado. Se trató de un estudio explicativo no experimental aplicando la técnica de ecuaciones estructurales.
Resultados. Los hallazgos indican que características como ser hombre, de mayor edad, con estilo teórico y/o reflexivo favorecen el promedio académico, así como la apertura mental y el tesón, mientras que la motivación identificada y la amotivación, afectan negativamente el PA en los estudiantes.
Discusión y conclusiones. El modelo propuesto concuerda con los estudios en modalidad presencial al demostrar que tanto las variables sociodemográficas como las no cognitivas son relevantes para explicar el logro académico en modalidad a distancia.

Authors: Suria Martinez Raquel
Published: May 2023

Introducción. En este trabajo se identifica si existen perfiles diferenciados en función del peso que cobra cada factor resiliente en el profesorado de secundaria y si los grupos resilientes obtenidos difieren en tecnoestrés.

Método. La Escala de resiliencia (1993) y el Cuestionario de Recursos, Emociones/Experiencias y Demandas en usuarios de TIC (2004), fueron administrados a 232 profesores, de entre 27 y 60 años (M = 30.60; DT = 10.44) de Alicante (España).

Resultados. El análisis de conglomerados halló una solución de tres clústeres de resiliencia: un perfil de resiliencia generalizada, un segundo perfil de niveles bajos en las tres dimensiones resilientes y un grupo con un elevado nivel de autodisciplina y bajo en aceptación de uno mismo y de la vida y en competencia social, reflejándose menor tecnoestrés en el perfil de alta resiliencia generalizada.

Discusión y conclusiones. Estos resultados apuntan la necesidad de incidir en el desarrollo de la resiliencia para enfrentar el estrés derivado de las tecnologías.

Authors: Emelyanova Olga O. , Zikirjahodzhaev Aziz D. , Saribekyan Erik K. , Filonenko Elena V.
Published: May 2023

Extramammary Paget's disease is a slow-growing cutaneous intraepithelial adenocarcinoma of the apocrine glands in the anogenital and axillary regions. The disease is extremely rare, affects predominantly postmenopausal women, and has nonspecific clinical caracteristics, so that it can take 210 years from the first clinical signs to diagnosis.
The vulva and the perianal region are the most affected zones. Extramammary Pagets disease is clinically manifested as well-defined erythematous plaques with secondary changes, such as scaling, ulceration and even bleeding.
Differential diagnosis is made between primary and secondary forms of Extramammary Pagets disease, candidiasis, contact dermatitis, Crohn's disease, eczema, erosive lichen planus, hydradenitis suppurativa, Langerhans cell histiocytosis, sclerosing lichen, psoriasis, squamous cell carcinoma in situ, amelanotic melanoma and mycosis fungoide.
Treatment mainly includes the surgical component, as well as the use of photodynamic therapy, cytostatic agents, and, depending on the stage, systemic chemotherapy.

Objectives:

Hepatitis B virus (HBV) infection is a global public health problem, even though its prevalence is disproportionately high in resource-limited countries, it is still under-reported. Mother-to-child transmission is a major route of HBV transmission in an endemic region like sub-Saharan Africa. This study assessed the prevalence of HBV infection and the effect of service charge on hepatitis B surface antigen (HBsAg) disease notification among pregnant women who attended the antenatal clinic at General Hospital, Otukpo, Benue State, Nigeria.

Materials and Methods:

A retrospective cohort study with convenient sampling techniques were used for all pregnant women enrolled for antenatal care (ANC) within the reviewed period. Chi-square (χ2) test was used for the test of association between the independent variable and the main outcome of the study, with statistical significance set at P = 5%.

Results:

Of the total 1144 cases reviewed, 843 (73.7%) were tested for human immunodeficiency virus (HIV) and 301 (26.3%) were tested for HBsAg. The test for HIV was free while that of HBsAg was done out of pocket expenses. The majority of the women were between 25 and 30 years with a mean age of 25 ± 9.54 years. The seropositive rate for HIV was 2.4% (n = 20) while that of HBsAg was 5.6% (n = 17). The relationship between underreporting of positive and negative cases of HBsAg and service charges was statistically significant (P < 0.005).

Conclusion:

To achieve the global goal of elimination of HBV and, or reducing the prevalence of HBsAg in general population, the free opt-in screening just like in the case of HIV must be adopted for all pregnant women accessing ANC in public health facilities. This will inform both prevention, control, and antiviral management intervention strategies.
The role of ligand shell density in the diffusive behavior of nanoparticles in hydrogels
Authors: Moncure Paige , Millstone Jill , Laaser Jennifer
Published: May 2023

The diffusion coefficients of poly(ethylene glycol) methyl ether thiol (PEGSH) functionalized gold nanoparticles (NPs) with different effective grafting densities were measured in polyacrylamide hydrogels. The NP core size was held constant, and the NPs were functionalized with mixtures of long polymeric ligands (either 1 or 2 kDa PEGSH) and short oligomeric ligands (254 Da PEGSH). The ratio of short and long ligands was varied such that the grafting density of the high molecular weight (MW) ligand ranged from approximately 1-100 high MW ligands/NP. The diffusion coefficients of the NPs were then measured in gels with varying mesh sizes. The measured diffusion coefficients decreased with increasing high MW ligand density. Interestingly, the diffusion coefficients for NPs with high effective grafting densities were well-predicted by their hydrodynamic diameters, but the diffusion coefficients for NPs with low effective grafting densities were higher than expected from their hydrodynamic diameters. These results suggest that crowding in the NP ligand shell influences the mechanism of diffusion, with lower grafting densities allowing ligand chain relaxations that facilitate movement through the gel. This work brings new insights into the factors that dictate how NPs move through hydrogels and will inform the development of models for applications such as drug delivery in complex viscoelastic biological materials.

Solution processed semiconductors are in demand for present and next-generation optoelectronic technologies ranging from displays to quantum light sources because of their scalability and ease of integration into devices with diverse form factors. One of the central requirements for semiconductors used in these applications is a narrow photoluminescence (PL) linewidth. Narrow emission linewidths are needed to ensure both color and single-photon purity, raising the question of what design rules are needed to obtain narrow emission from semiconductors made in solution. In this review we first examine the requirements for colloidal emitters for a variety of applications including light-emitting diodes, photodetectors, lasers, and quantum information science. Next, we will delve into the sources of spectral broadening, including “homogeneous” broadening from dynamical broadening mechanisms in single-particle spectra, heterogeneous broadening from static structural differences in ensemble spectra, and spectral diffusion. Then, we compare the current state of the art in terms of emission linewidth for a variety of colloidal materials including II-VI quantum dots (QDs) and nanoplatelets, III-V QDs, alloyed QDs, metal-halide perovskites including nanocrystals and 2D structures, doped nanocrystals, and, finally, as a point of comparison, organic molecules. We end with some conclusions and connections, including an outline of promising paths forward.
Effects of dietary tryptophan on cannibalism, survival and growth of Wallago attu (Bloch & Schneider, 1801) juveniles

Published: May 2023

This study aims to evaluate the effects of supplemented commercial diets with tryptophan (TRP) on plasma serotonin, cannibalism, survival rate, and growth of Wallago attu (helicopter catfish). After one week of acclimation, 3,200 juveniles of helicopter catfish (BW = 2.5 ± 0.27 g, total length = 5.6 ± 0.43 cm) were randomly assigned for the experiment in fifteen plastic tanks (200 L). The experiment was conducted with five treatments (CT – 0 g TRP/kg – control group, T1 – 5 g TRP/kg, T2 – 10 g TRP/kg, T3 – 20 g TRP/kg, and T4 – 40 g TRP/kg) in a completely randomized design with three replications for four weeks. The results from the enzyme-linked immunosorbent assay reveal that TRP-supplemented diets effectively increased the serotonin level (5-HT) in the plasma of the catfish. The serotonin level increased with the dose of TRP added to the feed. Furthermore, a higher TRP level significantly decreased cannibalism and improved the final survival of the fish. However, the fish’s growth rate among treatments T1, T2, T3, and T4 was not significantly different, but there was a statistical difference between the experimental treatments and the CT treatment. The findings of this study suggest that TRP could be supplemented at a dose of 20 g·kg–1 to the feed to reduce cannibalism and improve the final survival of helicopter catfish.
First-principles study on the structural and electronic properties of single-layer MoSi2N4
Authors: Nguyen Cuong Q. , Le Thi Thu Phuong , Nguyen Chuong V.
Published: May 2023

Motivated by the successful exfoliation of a novel two-dimensional MoSi2N4 materials, in this work, we investigate the structural and electronic properties of a novel single-layer MoSi2N4 and the effect of strain engineering by using the first-principles calculations based on the density functional theory. The single-layer MoSi2N4 has a hexagonal structure with a space group of P6m1, which is dynamically stable. The material exhibits a semiconducting characteristic with an indirect band gap of 1.80/2.36 eV calculated by using the PBE/HSE functional. The conduction band minimum at the K point of the material originates from the Mo atom, while its valence band maximum at the G point is contributed by the hybridization between the Mo and N atoms. The electronic properties of the single-layer MoSi2N4 can be modulated with strain engineering, giving rise to a transition from a semiconductor to a metal and tending to a change in the band gap. Our results demonstrate that the single-layer MoSi2N4 is a promising candidate for electronic and optoelectronic applications.

Published: May 2023

This paper presents a simple thermal-electrical model of a photovoltaic panel with a cooler-integrated sun tracker. Based on the model and obtained weather data, we analyzed the improved overall efficiency in a year as well as the performance in each typical weather case for photovoltaic panels with fixed-tilt systems with a tilt angle equal to latitude, fixed-tilt systems with cooler, a single-axis sun tracker, and a cooler-integrated single-axis sun tracker. The results show that on a sunny summer day with few clouds, the performance of the photovoltaic panels with the proposed system improved and reached 32.76% compared with the fixed-tilt systems. On a sunny day with clouds in the wet, rainy season, because of the low air temperature and the high wind speed, the photovoltaic panel temperature was lower than the cooler’s initial set temperature; the performance of the photovoltaic panel with the proposed system improved by 12.55% compared with the fixed-tilt system. Simulation results show that, over one year, the overall efficiency of the proposed system markedly improved by 16.35, 13.03, and 3.68% compared with the photovoltaic panel with the fixed-tilt system, the cooler, and the single-axis sun tracker, respectively. The simulation results can serve as a premise for future experimental models.
Methylation of lysine 36 on histone H3 is required to control transposon activities in somatic cells
Authors: Lindehell Henrik , Schwartz Yuri B , Larsson Jan
Published: May 2023

Transposable elements constitute a substantial portion of most eukaryotic genomes and their activity can lead to developmental and neuronal defects. In the germline, transposon activity is antagonized by the PIWI-interacting RNA pathway tasked with repression of transposon transcription and degrading transcripts that have already been produced. However, most of the genes required for transposon control are not expressed outside the germline, prompting the question: what causes deleterious transposons activity in the soma and how is it managed? Here, we show that disruptions of the Histone 3 lysine 36 methylation machinery led to increased transposon transcription inDrosophila melanogasterbrains and that there is division of labour for the repression of transposable elements between the different methyltransferases Set2, NSD, and Ash1. Furthermore, we show that disruption of methylation leads to somatic activation of key genes in the PIWI-interacting RNA pathway and the preferential production of RNA from dual-strand piRNA clusters.

Metagenomic exploration of natural product biosynthesis in marine microbial communities
Authors:   , Nowak Vincent
Published: May 2023

Marine environments are home to a staggering diversity of microbial life, the majority of which has yet to be cultivated in a laboratory setting. These microbes are the base of the food chain that supports marine life and key drivers of the planets biogeochemical cycles. Marine microbes also produce biologically active natural products, yet surprisingly little is known about the diversity and ecological roles of microbial natural products in marine ecosystems. Beyond their possible ecological roles, natural products from marine microbes are of immense interest as a source of new drug leads. The aim of this thesis was to develop experimental and bioinformatic approaches for the metagenomic exploration of marine microbes. Initial work was conducted on planktonic marine microbes and sea ice microbes with the goal of developing a robust method for constructing large insert (30-45 kb) metagenomic libraries from these challenging low-biomass samples. A series of optimisation experiments were conducted to this end, with some success, however this goal proved intractable given the sample availability and time frame of this thesis. Instead, direct shotgun sequencing, metagenome binning and biosynthetic pathway analysis was used to examine the microbiomes of six Tongan marine sponges. This collection included a sample of the marine sponge Cacospongia mycofijiensis, which contained high levels of the cytotoxic polyketides (-)-zampanolide, latrunculin A and laulimalide A. A large insert (30-45 kb) metagenomic library was ultimately constructed from this sponge sample. The newly sequenced Tongan sponge metagenomes were also compared to a collection of marine sponge metagenomes from New Zealand as well as publicly available metagenomes obtained from Mediterranean marine sponges. In addition to developing robust and cost effective experimental and bioinformatic techniques for marine sponge microbiome analysis, key findings from this work were: (1) Host taxonomy and large-scale oceanographic location both appear to be important drivers of microbial community composition (2) Tongan marine sponge microbiomes are more similar to Mediterranean sponge microbiomes than New Zealand marine sponge microbiomes (3) Tongan marine sponge microbiomes are rich in natural product biosynthesis, particularly in ribosomally synthesized and post-translationally modified peptides with potential antimicrobial activity that may play an important defensive role in the context of this symbiosis.

Business Ecosystems and Human Potential: Interrelation and Legal Regulation
Authors:   Financial University,  Moscow, Russia, Vasilyeva O.N.
Published: May 2023

The subject of the study is the impact of business ecosystems on human potential. The purpose of the work is to establish the procedure for regulating the activities of business ecosystems. The article examines the categories of business ecosystems, their impact on the development of markets for goods and services. Based on a survey of users of such major Russian business ecosystems as Yandex, Wildberries, Beber, etc., the most significant positive and negative aspects of the life of business ecosystems for participants in economic relations have been identified. The most optimal approaches to their regulation are determined based on the analysis of the results of a survey of users of business ecosystems and the activities of the largest Russian companies. It has been established that the level of efficiency, productivity and growth potential is significantly higher in the business ecosystem than in standard format enterprises, and the degree of its competitiveness in the eyes of consumers is significantly higher, i.e. ecosystem-specific features affect the expansion of human potential. It is determined that the formation of business ecosystems has significantly expanded human potential. An important element peculiar to ecosystems and affecting the capabilities of the enterprise is shown — technological equipment, which allows, on the basis of multifunctional Internet platforms, to personalize the approach to the relationship between the enterprise and consumers of its products as much as possible, making them more stable. Conclusions are drawn about the need to expand self-regulation of business ecosystems.

Esta pesquisa aborda aspectos do contexto funerário de engenhos, buscando compreender o registro arqueológico do cemitério da capela do Engenho Jaguaribe, litoral norte do estado de Pernambuco. Pesquisas sistemáticas realizadas entre 2015 e 2019 evidenciaram um espaço extramuros destinado às inumações de pessoas com identidades desconhecidas e associadas a uma estrutura de pedras parcialmente evidenciada, resultando em uma série de questionamentos acerca do funcionamento dessa área de enterramentos e a quais sujeitos sociais teria sido destinada. A obtenção de determinados elementos do perfil bioantropológico, como produto da interface de propostas metodológicas da Bioarqueologia, possibilitou analisar remanescentes ósseos de cinco indivíduos. Foram utilizados procedimentos métricos e morfológicos para diagnose sexual, estimativa de idade, ancestralidade geográfica e estatura. Os resultados indicam que os adros do templo se configuram como funcionalmente destinados aos indivíduos masculinos e femininos, contendo sepultamentos de crianças, jovens adultos, adultos e adultos maduros, com características que sugerem forte contato interétnico.

Local Microorganisms (MOL) is a type of organic fertilizer that is environmentally friendly, inexpensive and easy to produce independently. The hope is that MOL can support organic farming so that farmers can produce agricultural products that are safe and healthy for consumption. MOL is known to have a variety of multipurpose microorganisms and is rich in nutrients. Therefore, this information is important to be disseminated to the millennial generation on various occasions including Community Service activities carried out by lecturers at universities. The target of this activity is the students of the public school, Vocational High School (VHS) 2 Kota Komba, which is located in East Manggarai Regency, East Nusa Tenggara Province. This activity aims to provide students with an understanding of the importance of environmentally friendly agriculture by utilizing forage and household waste as raw materials for making MOL and how to make it independently. The implementation of this activity is in the form of socialization and training. The socialization was carried out to provide theoretical knowledge to partners about the benefits and advantages obtained from MOL, then continued with training and direct assistance in making it involving 22 students. The training was conducted by dividing participants into 4 working groups (5‒6 people/group). The process of making MOL is carried out according to the work procedures that have been prepared. The results of the socialization, training and mentoring activities for making MOLs can add new insights and knowledge and form work skills for partners in making MOLs. This is shown by the active participation of the students in discussions and enthusiasm in the process of making MOL until it is successful.

Kajian ini adalah sebuah refleksi kritis terhadap praktis pendidikan kewirausahaan untuk menemukan kelemahan dan upaya perbaikan yang potensial dilakukan. Kajian ini menggunakan penelitian kepustakaan yang dilakukan terhadap hasil penelitian yang ada di database google scholar. Data dalam penelitian ini dianalisis dengan pendekatan tematik. Kajian ini menunjukkan adanya inkonsistensi hasil penelitian terkait dampak pendidikan kewirausahaan bagi penyiapan lulusan sebagai agen perubahan dan pemberdayaan masyarakat. Kelemahan yang menjadi pemicu inkonsistensi hasil penelitian tersebut adalah lemahnya landasan filosofi pelaksanaan, tujuan dan orientasi yang rancu dan tidak terdefinisikan dengan jelas, rancangan dan implementasi pembelajaran yang tidak relevan dengan konteks dan karakteristik peserta didik, serta evaluasi terhadap hasil dan outcome yang menghasilkan informasi yang bias. Beberapa perbaikan yang bisa dilakukan antara lain reorientasi arah pelaksanaan, redesain implementasi pembelajaran, serta internalisasi nilai dan budaya kewirausahaan di internal dan eksternal kampus melalui kolaborasi antara lembaga pendidikan dengan pelaku usaha dan pemerintah. Rekomendasi perbaikan tersebut masih memerlukan investigasi lebih lanjut untuk mengembangkan model yang didukung oleh data empiris.
