Published: March 2023

The physical properties of meteoroids producing meteor plasma non-field-aligned irregularities (NFAI) in the Earth’s atmosphere are poorly known. Here we report a complete picture of a fireball and mesospheric NFAI that it produced for the first time. Simultaneous radar and optical observations were made by the recently completed facility, Meteor and ionospheric Irregularity Observation System. The observations show that the mesospheric NFAI were clustered into three patches where the optical meteor flares took place, instead of being generated continuously along the whole meteor path. It is very likely that nanometer-or-larger-sized dust particles could be directly generated via meteoroid fragmentation at the flaring points and thus promote the generation of NFAI patches. The properties of the parent meteoroid show a chondrite type and a Jupiter family comet orbit, with Na/Mg and Fe/Mg intensity ratios of 1.5 and 1, respectively, photometric mass of about 4 g, and fragmentation strengths of around 10–74 kPa. The results suggest that the direct generation of dust particles, which was previously observed in the atmospheric disintegration of a kiloton-scale meteoroid, could be extended to the much smaller gram-scale meteoroids. Since meteoroids having such characteristics or more fragile material are not unusual, further studies leading to a better understanding of meteor mass deposition in the upper atmosphere, which consider the dust particles directly generated via gram-scale meteoroid fragmentation, are extremely important.

Published: March 2023

We present a multi-epoch spectroscopic study of LkCa 4, a heavily spotted non-accreting T Tauri star. Using SpeX at NASA’s Infrared Telescope Facility (IRTF), 12 spectra were collected over five consecutive nights, spanning ≈1.5 stellar rotations. Using the IRTF SpeX Spectral Library, we constructed empirical composite models of spotted stars by combining a warmer (photosphere) standard star spectrum with a cooler (spot) standard weighted by the spot filling factor, f
spot. The best-fit models spanned two photospheric component temperatures, T
phot = 4100 K (K7V) and 4400 K (K5V), and one spot component temperature, T
spot = 3060 K (M5V) with an A

V
of 0.3. We find values of f
spot to vary between 0.77 and 0.94 with an average uncertainty of ∼0.04. The variability of f
spot is periodic and correlates with its 3.374 day rotational period. Using a mean value for f
mean
spot to represent the total spot coverage, we calculated spot corrected values for T
eff and L
⋆. Placing these values alongside evolutionary models developed for heavily spotted young stars, we infer mass and age ranges of 0.45–0.6 M
⊙ and 0.50–1.25 Myr, respectively. These inferred values represent a twofold increase in the mass and a twofold decrease in the age as compared to standard evolutionary models. Such a result highlights the need for constraining the contributions of cool and warm regions of young stellar atmospheres when estimating T
eff and L
⋆ to infer masses and ages as well as the necessity for models to account for the effects of these regions on the early evolution of low-mass stars.
Machine Learning Detects Multiplicity of the First Stars in Stellar Archaeology Data

Published: March 2023

In unveiling the nature of the first stars, the main astronomical clue is the elemental compositions of the second generation of stars, observed as extremely metal-poor (EMP) stars, in the Milky Way. However, no observational constraint was available on their multiplicity, which is crucial for understanding early phases of galaxy formation. We develop a new data-driven method to classify observed EMP stars into mono- or multi-enriched stars with support vector machines. We also use our own nucleosynthesis yields of core-collapse supernovae with mixing fallback that can explain many of the observed EMP stars. Our method predicts, for the first time, that 31.8% ± 2.3% of 462 analyzed EMP stars are classified as mono-enriched. This means that the majority of EMP stars are likely multi-enriched, suggesting that the first stars were born in small clusters. Lower-metallicity stars are more likely to be enriched by a single supernova, most of which have high carbon enhancement. We also find that Fe, Mg. Ca, and C are the most informative elements for this classification. In addition, oxygen is very informative despite its low observability. Our data-driven method sheds a new light on solving the mystery of the first stars from the complex data set of Galactic archeology surveys.
Association Between Magnetic Pressure Difference and the Movement of Solar Pores
Authors: Mendoza Merlin M. , Lin Chia-Hsien
Published: March 2023

Solar pores are closely related to the concentration, dissipation, and transportation of solar magnetic flux. Their observable characteristics can provide constraints on models and simulations of magnetic flux emergence and formation. The specific property investigated in this study is their horizontal movement. The aim is to investigate whether the movement is correlated with any observable quantities. Our statistical analysis of 61 compact pores identified from the Spaceweather HMI Active Region Patches (SHARP) from 2011 to 2018 indicates that the direction of movement is often either parallel or antiparallel to the direction of maximum magnetic pressure difference (dP
mag) at the opposite sides of the edges of the pores. The correlation coefficients for both the parallel and antiparallel cases are higher than 0.74. Despite the high correlation, our analysis using the transfer entropy indicates no significant causal relationship between the direction of motion and the direction of maximum dP
mag.
Green spaces in Sofia – analyses of spatial distribution
Authors: Todorova Elena
Published: March 2023

Green spaces in urban ecosystems is the main provider of a variety of ecosystem services. It is important for a city that undergoes dynamic changes in size, structure and number of inhabitants to manage bal-anced urban green spaces. Using the geographical information systems, this research investigates the green spaces within the building boundary of Sofia by administrative regions and confirms and demon-strates the spatial deficiencies in their distribution. The proportion of parks and gardens and open green spaces by region is taken into consideration and supplemented with analysis of the density of the tree coverage in the park. The green area per capita is calculated to demonstrate how the coverage with green spaces relates to the population. The results outline some main issues that urban development is facing towards sustainability. If considered by the planning and management of the city this could help respond to the contemporary challenges and adopt policies for a vital, healthy, and attractive environment for the capital’s residents.
Les majors pétrolières, du tout pétrole aux énergies renouvelables, décryptage d’un changement de modèle ou de communication
Authors: Augé Benjamin
Published: March 2023

Le changement climatique oblige les firmes pétrolières privées comme publiques à faire évoluer, à la marge, leur modèle, jusqu’alors basé uniquement sur la production d’hydrocarbures. Certains acteurs, comme les majors européennes, deviennent des énergéticiens généralistes utilisant l’extraordinaire capital généré par leur manne pétrolière en vue de financer les acquisitions dans les énergies renouvelables, tout en ne baissant pas la production d’hydrocarbures. D’autres au contraire, comme les firmes américaines, minimisent le changement, en ne parlant que de limiter les effets de leur production de pétrole et de gaz. Les acteurs asiatiques et golfiques des hydrocarbures sont quant à eux à des stades très différents de leur réflexion, certains finançant directement de grandes fermes solaires, pour maximiser l’exportation de gaz et de pétrole alors qu’en Chine, où les acteurs des énergies fossiles restent dans leur corps de métier traditionnel, c’est à d’autres acteurs étatiques et privés qu’échoie le rôle de développer les renouvelables. Si la plupart des régions bénéficient de ces nouveaux investissements des pétroliers dans les énergies vertes, l’Afrique reste à quai.
Enjeux géopolitiques autour du partage et du contrôle de trois grands fleuves transfrontaliers en Asie du Sud (Gange, Indus et Brahmapoutre)
Authors: Oulkebous Leila
Published: March 2023

Le Gange, le Brahmapoutre et l’Indus : ces trois fleuves majeurs de l’Asie du Sud constituent des artères centrales à l’échelle de la région et près de 700 millions de personnes dépendent de ces cours d’eau pour leurs besoins en eau. Ces fleuves transfrontaliers sont au cœur de rivalités géopolitiques importantes entre les États riverains. La Chine et l’Inde en particulier sont deux grandes puissances économiques rivales qui misent en grande partie sur le contrôle des ressources en eau à travers la mise en place d’aménagements comme des barrages ou des canaux de dérivation. Dans cet article, nous allons nous intéresser à l’eau en tant que ressource stratégique et voir dans quelle mesure elle se place au cœur d’enjeux de partage et de contrôle en Asie du Sud. Nous chercherons à analyser en quoi les problématiques d’usage et de répartition des ressources en eau à l’échelle de ces grands fleuves transfrontaliers mettent en lumière les rivalités entre puissances régionales.
Sécurité alimentaire et géopolitique des protéines : enjeux et perspectives d’une ressource en mutation
Authors: Antoine Olivier , Thiercelin Éloïse
Published: March 2023

Au cours des cent dernières années, l’accélération de la croissance démographique mondiale, l’urbanisation de la population et la hausse phénoménale de la consommation de viande ont provoqué une explosion de la demande de protéines, entraînant une évolution des systèmes alimentaires ainsi que des mutations agricoles au profit notamment de la culture du soja. Protéine star du système de production intensive de viande, elle s’est imposée comme un pilier de la sécurité alimentaire mondiale et l’objet d’enjeux géopolitiques. Lourdement critiquée pour les conséquences de sa production sur l’environnement, la production de soja est remise en question au profit de stratégies d’indépendance protéique privilégiant de nouvelles ressources. Ces alternatives, où l’agriculture ne joue plus un rôle central, pourraient redéfinir une nouvelle géopolitique des protéines et, à terme, marquer un possible tournant civilisationnel.

Authors: Palle Angélique
Published: March 2023

Cet article interroge la relation de dépendance entre la politique interne de l’énergie en Chine et le projet des routes de la soie. Il propose dans un premier temps une analyse des facteurs de transformation du mix énergétique chinois et de leurs effets sur la politique chinoise de l’énergie. Elle se trouve aujourd’hui face à un paradoxe, celui d’une double injonction au développement et à la croissance d’une part, et à la maîtrise des externalités environnementales de cette croissance d’autre part. Un paradoxe que le gouvernement chinois cherche à résoudre en s’appuyant sur une politique extérieure d’acquisition de ressources et de développement du secteur énergétique. Cette politique extérieure est contrainte par l’environnement régional de la Chine que l’on analysera dans un second temps avant de montrer comment le projet des routes de la soie constitue dans sa dimension énergétique une tentative de résolution de ce paradoxe énergétique chinois.

Authors: Li Hui , Gong Rongrong , Hou Pengfei , Xing Libao , Jia Dongbao , Li Haining
Published: March 2023

Due to the characteristics of online learning resource recommendation such as large scale, uneven quality and diversity of preferences, how to accurately obtain various personalized learning resource lists has become an urgent problem to be solved in the field of online learning resource recommendation. This paper proposes an online learning resource recommendation model based on the improved NSGA-Ⅱ algorithm, which integrates the Tabu search algorithm to improve the local search ability of NSGA-Ⅱ algorithm. It takes background fitness, cognitive fitness and diversity as the objective functions for optimization. The dynamic updating of crowding degree is used to avoid the risk that the individuals with low crowding degree in the same area are deleted at the same time. Meanwhile, an adaptive genetic algorithm is applied to assign the optimal crossover rate and the mutation rate according to individual adaptability level, which ensures the convergence of genetic algorithm and the diversity of population. The experimental results show that the proposed model is superior to the traditional recommendation algorithm in terms of accuracy index, mean fitness, recall rate, F1 mean, HV, GD and IGD, etc., thus verifying the feasibility and effectiveness of the algorithm.

Concepções e objetivos da política imigratória brasileira, 1850-1889
Authors: Da Silva Ferreira Luiz Mateus
Published: March 2023

Este artigo examina a discussão política em torno do ideal imigracionista brasileiro no período 1850-1889. As principais fontes utilizadas são os anais do parlamento brasileiro, relatórios oficiais e registros de época. O objetivo desta análise é captar as concepções de duas importantes correntes políticas imigracionistas brasileiras do século XIX: a governamental, especialmente representada pela classe política e intelectual próxima a D. Pedro II; e a da aristocracia de fazendeiros, principalmente os cafeicultores. Este artigo mostra que, apesar da influência política dessa classe fundiária, o governo imperial brasileiro procurou desvincular a imigração europeia para o Brasil dos interesses imediatos dos fazendeiros.
The interplay between physiotherapist and exercise physiologist in the exercise oncology program
Authors: Frajacomo Fernando , Deminice Rafael
Published: March 2023

Exercise is a relevant tool in the oncology rehabilitation program due to restoring functional capacity, improving quality of life, and preventing early cancer mortality, mainly in unfit cancer patients. According to a systematic physical evaluation and risk stratification model, exercise physiologists (or equivalent) and physiotherapists with additional cancer exercise training are candidates to provide and supervise exercise to cancer survivors. However, the referral pathways are unclear, and a few cancer survivors are educated about personalized exercise oncology programs. This article aims to engage and stimulate additional training of Exercise physiologists and Physiotherapists in a collaborative exercise oncology program and propose a dynamic and supervised model to attend to the emerging multidisciplinary scenario of cancer.

Published: March 2023

O objetivo deste estudo foi analisar as concepções e princípios de prática de liderança de treinadores de alta performance do futebol brasileiro. Participaram do estudo, por meio de entrevistas semiestruturadas, cinco treinadores de futebol masculino que já atuaram na 1ª divisão brasileira, conquistando títulos estaduais e nacionais e com experiência em equipes e seleções estrangeiras. As principais evidências apontam para competências gerais, estratégias de gestão, conhecimento profissional, princípios e valores individuais. Conclui-se que os treinadores possuem conhecimento processual tácito instintivo que resulta numa filosofia de liderança desconexa e competências interpessoais mais evidentes. Sugere-se que os treinadores utilizem o modelo trifásico de eficácia de liderança e a prática da reflexão sistematiza de forma a potenciarem a sua eficácia de liderança.
Physical education teachers in times of pandemic
Authors: Gutierrez Ariel , Tabora Adrian R. , Gama Jaymark L.
Published: March 2023

This paper reports on a study that investigated the experiences of 25 physical education (PE) teachers from public and private schools in Angeles City, Philippines, during the COVID-19 pandemic. The study found that many PE teachers encountered various challenges and were hesitant and unconfident about teaching PE during the pandemic. Additionally, many PE teachers were given non-teaching assignments and responsibilities, which added to their workload. The study highlights the importance of equipping teachers with the necessary skills and knowledge to adapt to the new teaching and learning modalities during the pandemic and providing support for PE teachers during this challenging time. The paper concludes by suggesting that future research could investigate the specific strategies and approaches that have been most effective in helping PE teachers overcome the challenges they face in teaching during the pandemic and the long-term effects of the pandemic on the teaching and learning of physical education.
A Therapeutic Vaccine in Combination with Cyclic GMP–AMP Cures More Differentiated Melanomas in Mice
Authors: Alam Md Masud , Gower Timothy , Jiang Mengmeng , Oppenheim Joost J , Yang De
Published: March 2023

We have identified a combinational immunotherapy termed TheraVac vaccine (TheraVac) that can cure multiple large established mouse tumors, but it failed to cure melanoma in mice. TheraVac consists of an immunostimulating arm containing an agonist (HMGN1 [N1]) for TLR4 and an agonist (R848) for TLR7/8 that synergize to activate tumor-infiltrating dendritic cells (DCs) and promote Th1 immune responses. The second arm uses an immune checkpoint blockade, anti-PDL-1, to diminish tumor-associated immunosuppression. In this study, we investigated supplementation of TheraVac by a stimulator of IFN genes (STING) agonist, cyclic GMP–AMP (cGAMP), because together they synergize in activating DCs and produced more immunostimulating IL-12p70 and TNF-α cytokines. The synergistic activation and maturation of DCs is dependent on the activation of tank binding kinase-1 (TBK1). Treatment of three different melanin-producing mouse melanomas (B16F1, M3, and M4) with intratumoral delivery of cGAMP and TheraVac eradicated 60–80% of these melanomas. Immunoprofiling of M3 tumor treated with TheraVac plus cGAMP showed an increase in CD8+ CTLs and macrophages in the tumor. There was also a marked increase of CD4, CD8 effector and memory T cells and generation of functional tumor-specific CTLs in tumor-draining lymph nodes. The resultant tumor-free mice were selectively resistant to subsequent challenge with the same tumors, indicating long-term tumor-specific protective immunity. Overall, our findings have important implications for clinical trials with a combination of these immunotherapeutics to cure melanin-producing human melanomas, without the need for exogenous tumor Ags and no clear toxic effects in mice.
Innate Immune Zonation in the Liver: NF-κB (p50) Activation and C-Reactive Protein Expression in Response to Endotoxemia Are Zone Specific

Published: March 2023

Hepatic innate immune function plays an important role in the pathogenesis of many diseases. Importantly, a growing body of literature has firmly established the spatial heterogeneity of hepatocyte metabolic function; however, whether innate immune function is zonated remains unknown. To test this question, we exposed adult C57BL/6 mice to endotoxemia, and hepatic tissue was assessed for the acute phase response (APR). The zone-specific APR was evaluated in periportal and pericentral/centrilobular hepatocytes isolated using digitonin perfusion and on hepatic tissue using RNAscope and immunohistochemistry. Western blot, EMSA, chromatin immunoprecipitation, and immunohistochemistry were used to determine the role of the transcription factor NF-κB in mediating hepatic C-reactive protein (CRP) expression. Finally, the ability of mice lacking the NF-κB subunit p50 (p50−/−) to raise a hepatic APR was evaluated. We found that endotoxemia induces a hepatocyte transcriptional APR in both male and female mice, with Crp, Apcs, Fga, Hp, and Lbp expression being enriched in pericentral/centrilobular hepatocytes. Focusing our work on CRP expression, we determined that NF-κB transcription factor subunit p50 binds to consensus sequence elements present in the murine CRP promoter. Furthermore, pericentral/centrilobular hepatocyte p50 nuclear translocation is temporally associated with zone-specific APR during endotoxemia. Lastly, the APR and CRP expression is blunted in endotoxemic p50−/− mice. These results demonstrate that the murine hepatocyte innate immune response to endotoxemia includes zone-specific activation of transcription factors and target gene expression. These results support further study of zone-specific hepatocyte innate immunity and its role in the development of various disease states.
Should extra virgin olive oil production change the approach? A systematic review of challenges and opportunities to increase sustainability, productivity, and product quality
Authors: Cappelli Alessio , Lupori Lucrezia , Cini Enrico
Published: March 2023

Extra virgin olive oil is constantly gaining interest for its outstanding health and nutritional properties. However, the production process generates roughly four times more waste than the quantity of oil. For this reason, improvements in extra virgin olive oil production and in the valorisation of olive mill by-products are urgently needed, thus motivating this work. The first aim of this review is to summarise current knowledge regarding machines, plants, and processes in extra virgin olive oil production. The second aim is to suggest specific innovations and improvement strategies to increase sustainability, productivity, profitability, and quality. This review clearly highlighted the copious advantages of modern production plants, which can control oxidation processes, avoid temperature increases, and significantly improve the quality of extra virgin olive oil. However, the production chain must face the monumental environmental sustainability challenge. In this direction, this review highlighted that scientific and technological research has made great strides in managing olive mill by-products, suggesting several strategies related to the recovery of polyphenols and applications in agriculture, feed, and food. However, to succeed in this ambitious project, harmonious teamwork between European policies, states, regions, and private companies is needed.

As a specific type of asthenoteratozoospermia, multiple morphological abnormalities of the sperm flagella (MMAF) is characterized by composite abnormalities, including absent, short, coiled, angulation, and irregular-caliber flagella. Mutations in cilia- and flagella-associated protein 43 (CFAP43) are one of the main causative factors of MMAF established to date. To identify whether there are other CFAP43 mutations related to MMAF and to determine the clinical outcomes of assisted reproductive technology for patients with MMAF harboring different mutations, we recruited and screened 30 MMAF-affected Chinese men using a 22-gene next-generation sequencing panel. After systematic analysis, seven mutations in CFAP43, including five novel mutations and two previously reported mutations, were identified from four families and related to MMAF in an autosomal recessive pattern. Papanicolaou staining, immunofluorescence, and electronic microscopy further clarified the semen characteristics and abnormal sperm morphologies, including disorganized axonemal and peri-axonemal structures, of the CFAP43-deficient men. The female partners of two patients were pregnant after undergoing assisted reproductive technology through intracytoplasmic sperm injection, and one of them successfully gave birth to a healthy boy. This study significantly expands the mutant spectrum of CFAP43, and together with the available information regarding male infertility and MMAF, provides new information for the genetic diagnosis and counseling of MMAF in the future.

ELECTROMAGNETIC WAVE MODEL OF HYDROGEN AND HELIUM DISTRIBUTION AT THE FORMATION OF THE SOLAR SYSTEM
Authors: Andrieieva O.L. , Tkachenko V.I. , Tkachenko G.A.
Published: March 2023

This paper considers the formation process of the protosolar hydrogen-helium cloud in chronological order. From the list of hypotheses about the solar system formation, the electromagnetic hypothesis of Alfvén was selected since it is based on the plasma state of the protosolar hydrogen-helium cloud. It presumably describes a supernova
explosion and its contribution to the solar system formation. The spatial-temporal dynamics of changes in the density and velocity of ions in a cylindrical two-component hydrogen-helium plasma is described. It is shown that the motion velocities of two-type particles represent Benard cells oscillating with different periods. The proposed
electromagnetic wave model was used to calculate the distribution of hydrogen and helium ions in the solar system at the beginning of its formation and after a supernova explosion.

O acometimento esofágico por doenças autoimunes tem sido cada vez mais reportado na literatura. A incidência e a prevalência de esofagite eosinofílica têm aumentado nas últimas décadas e as opções terapêuticas têm evoluído bastante, mas o corticoide tópico e o uso de inibidores de bombas de prótons permanecem como excelentes opções terapêuticas. Diversas doenças sistêmicas autoimunes podem cursar com acometimento esofágico secundário, com prejuízos da motilidade do corpo esofágico e do esfíncter esofagiano inferior. Esse acometimento se traduz principalmente em disfagia e refluxo gastroesofágico patológico, com suas complicações associadas. Atenção deve ser dada ao tratamento da doença do refluxo gastroesofágico nesses pacientes, de tal forma a melhorar a qualidade de vida e evitar complicações, como esôfago de Barrett e estenoses pépticas.

Published: March 2023

Nossas formas de comunicação estão em constante evolução desde a Pré-História. A expressão humana encontra diversos meios para gerar conexão e demonstrar ideias, planos e pensamentos. Uma das formas mais significativas da expressão humana se dá através da imagem. Orientamo-nos através de ícones, signos e imagens, como exemplificam as pinturas rupestres. Em paralelo, fomos desenvolvendo nossas noções de estética e de beleza, aprimorando nossas técnicas, criando e recriando padrões e interpretações sobre o mundo. Em constante evolução até os dias atuais, a comunicação através da imagem está presente em grande parte do nosso cotidiano, o que torna o design gráfico uma ferramenta muito importante e eficaz na funcionalidade desse processo. Dentre as atuações diversas do campo do design, focaremos no tema da Identidade Visual como estratégia fundamental na comunicação acerca de propósitos e valores profissionais ou empresariais. Para além do campo mercadológico, o papel de um bom projeto de identidade profissional tem como função primordial transmitir valores e objetivos de forma criativa e original, através da imagem, sem perder de vista a beleza e a harmonia, fatores importantes para o olhar humano desde sempre.

Published: March 2023

A publicidade na área médica sempre esteve sob a disciplina do Estado. O fato de “vender saúde” representa uma preocupação estatal protetiva, característica da forma de organização adotada pela sociedade brasileira. O avanço das redes sociais fez com que a exposição de profissionais e pacientes se potencializasse de maneira exponencial e sem fronteiras. As questões e reflexões que se colocam para os próximos anos são: devem-se estabelecer limites éticos para a utilização das redes sociais pelos médicos? Estamos preparados, enquanto sociedade, para as consequências de uma substancial modificação na relação entre médico, paciente e tecnologias digitais?

Climate change is a major concern around the world, particularly in developing countries like Mexico, where agriculture is the primary rural activity. As a hypothesis, it was proposed that high concentrations of CO2 in the atmosphere increase crop yields in Mexico, while the increase in temperatures and precipitation variations decrease them. The effect of climate change on agriculture in Mexico was examined using CO2 concentrations in the atmosphere, temperature, and precipitation. The climatic factor that has the greatest influence on agricultural productivity at the national level was identified. The ordinary least squares (MCO) method was used to estimate a Cobb-Douglas econometric model with statistical significance (p ≤ 0.05). CO2 concentration in the atmosphere was the climatic factor that had the greatest influence on agricultural production at the national level, with a direct relationship: if CO2 increased by 1 %, agricultural yield increased by 0.46 %. Corn and sugarcane, two of the three most important crops in terms of productive value in Mexico, are plants with a C4 photosynthetic pathway that benefit from the CO2 fertilization effect and mitigate the negative impact of climate change. However, in the last thirty years, global CO2 emissions have increased by an average of 0.5 % per year. If its growth continues to follow the same pattern in the short term, temperatures will rise, rainfall patterns will change, and agricultural production will be negatively affected.
Financial Dimension: A Tool for Teachers Financial Literacy

Teachers, as compared to the majority of the employed sectors in the country, are receiving salaries above the minimum wage set by law. This above the minimum salary, supposedly, places the average teacher above the poverty line as this is paramount to the demand of the job. But as can be observed around, many teachers experience financial struggles. With an end-view of improving financial literacy, this study was conducted to determine the level of financial literacy of the faculty of Isabela State University City of Ilagan Campus. A survey questionnaire was used to obtain the data needed to answer the objectives of the study. The results indicate that majority of the respondents are not financially literate to make critical decisions on financial concerns. The female respondents are more involved in the identified financial products compared to the male respondents. Included in the study was the respondents’ demographic profile as significant factor in their current financial literacy state. The results indicate that the demographic profile based on sex is not a significant factor that may spell a difference in the level of financial literacy among the respondents, while age, academic rank, and educational attainment are significant factors. The study also tested the relationship between the level of financial literacy of the respondents and their involvement on financial products. The data shows that there is a weak relationship between the two variables.

In this study, we investigated the effect of a heat source on blood flow through a gradient-tapered vessel under the influence of a gradient magnetic field by reformulating the problem using a mathematical model representing the blood momentum and energy equations. The partial differential equations were dimensionlessly scaled using a scaling parameter and further reduced to a system of ordinary differential equations. A coupled system of regular equations was solved using the series method to obtain analytical solutions for temperature and blood velocity profiles. Numerical simulations were performed using Wolfram Mathematica version 12 and varied parameters relevant to the investigation. The results showed that the relevant parameters—magnetic field, radiation parameter, Grashof number, and tilt angle contributed to liquid temperature and blood flow velocity, respectively. The novelty of this study is the fact that heat can be introduced from a heat source for the purpose of helping blood circulation, and magnetic fields tend to accelerate blood flow velocity.

This study focuses on investigating the effectiveness of Blended Learning in teaching Writing for English majors at Thai Nguyen University of Education. In order to eliminate subjectivity in the research, the author used simultaneously three means of data collection including test, questionnaire and observation. The results of the pre-test and post-test showed that students improved their Writing skills significantly after a semester of applying Blended Learning in teaching. The results of the students’ questionnaire and the teacher's observations also showed the students' positive attitudes towards this method. On this basis, Blended Learning is proposed to be applied more in teaching Writing for students at university.

Introduction: If someone dies, then all of his rights and obligations are transferred or transferred to his heirs. Purposes of the Research: This writing aims to find out the position of the heir to the inheritance, to find out who is entitled to the inheritance left by.Methods of the Research: The research method is very important to get accurate data so that it is said to be a tool or a way to guide in conducting research.Results of the Research: In the event of the death of a person, which is a legal event, it also causes legal consequences in the management and continuation of the matters and obligations of a person who dies. In addition, the occurrence of a position and the rights of the heirs will have consequences in the position and rights of the heirs to the inheritance. In addition, when viewed from the four groups above, they inherit sequentially, namely first those who are called or act as heirs of group I, then only groups II, III, and IV. In connection with the case example, all of the heirs have the same position and rights over the inheritance of the heirs, even Out-of-Marriage Children can inherit by replacement of place or better known as in Dutch "plaatsvervulling" and Out-of-Marriage Children inherit part of the rights from their parents. who has died Thus the Civil Code does not recognize the difference between men and women, married or unmarried, adults or underage, all of whom are considered as heirs who have the same position and rights over part of the inheritance which is an inherited property. left by the heir. Thus, if viewed from the examples of the cases studied, it can be seen that all children of the descendants of their heirs are entitled to enjoy the inheritance because the heirs have 7 children, so each division gets 1/7 of the inheritance. In addition, it is also necessary to know that if the testator wants to give his property before he dies to one of his children, it should be given with a written will or made by an authorized official.
