Half a century after the appearance of the celebrated paper by Serrin about overdetermined boundary value problems in potential theory and related symmetry properties, we reconsider semilinear polyharmonic equations under Dirichlet boundary conditions in the unit ball of $ \mathbb{R}^{n} $. We discuss radial properties (symmetry and monotonicity) of positive solutions of such equations and we show that, in conformal dimensions, the associated Green function satisfies elegant reflection and symmetry properties related to a suitable Kelvin transform (inversion about a sphere). This yields an alternative formula for computing the partial derivatives of solutions of polyharmonic problems. Moreover, it gives some hints on how to modify a counterexample by Sweers where radial monotonicity fails: we numerically recover strict radial monotonicity for the biharmonic equation in the unit ball of $ \mathbb{R}^{4} $.

English language proficiency of students in the Philippines is a point of concern by many institutions particularly as it was highlighted when the results of the first participation of the country in the Program for International Student Assessment (PISA) was released. The use of technology-aided educational applications dedicated to language learning, particularly those that can be accessed through mobile devices, is heavily studied internationally. However, in the Philippines, there is a limited number of developed mobile-supported applications that assist acquisition and learning of language, specifically English. Thus, the study aims were to develop a mobile learning application intended to assist students in learning a least mastered topic in English. The study utilized mixed-method descriptive research design. For the quantitative part, it employed a content-validated questionnaire to survey 132 fifth grade students, while for the qualitative part; it interviewed five English language teachers in the Philippines. A mobile learning application intended for smartphones in an Android OS was developed with focus on subject-verb agreement (SVA) as identified topic which was divided into 10 sub-topics. The application comprises two main parts: The Learn and Play Mode. Additionally, the application was also able to integrate an animated character named Alvin to simulate interaction. Alvin interacts with the user by narrating lessons, giving remarks, providing basic corrective feedback in the form of text, and expressing feelings based on the user’s inputs when doing exercises. The survey from students aged 10 to 12 years old showed that they have very often access to technological devices (i.e., desktop, laptops, tablet, smartphone) (M = 4.33) and that their technology aptitude in using them is high (M = 3.45). Furthermore, results also showed that students mostly prefer smartphones for their learning as it is their most available device at home. It is recommended to subject the developed mobile application to a user acceptance and usability testing in different educational contexts. Additionally, it is suggested to explore newer technologies like artificial intelligence to make the application intelligent and more responsive to students’ needs and inputs. Future studies may also include addition of new topics as well as developing similar applications that are localized and culturally-aware.

Alternative Computer Assisted Communicative Task-based Language Testing: New Communicational and Interactive Online Skills
Authors: Magal-Royo Teresa , Garcia Laborda Jesus , Mora Cantallops Marçal , Sánchez Alonso Salvador
Published: October 2021

Computer-assisted language learning knowledge tests should no longer be designed on traditional skills to measure individual competence through traditional skills such as reading, comprehension and writing, but instead, it should diagnose interactive and communication skills in foreign lan-guages. In recent years in online education, it has been necessary to review the concept of interactive competence in digital environments in a comple-mentary way to its traditional use. It is important to promote a new typolo-gy of alternative tasks and items in tests where examinees can prove a real interactive performance in communication and interaction through the digi-tal scenario. This should be done through tools that facilitate oral negotia-tion, the management and understanding of the information extracted from online repositories, the search for suitable online digital material, and the use of new modes of audio-visual communication. Although some of these tasks have been used in a complementary way in the design of language tests previously: it is true that they have not been applied in a coherent way to be used as an assessment tool. A first approach was made by Miguel Ál-varez, García Laborda & Magal-Royo (2021) in the development of oral ne-gotiation skills through the use of interactive tools. The current online as-sessment models analyzed by García Laborda & Álvarez Fernández (2021) indicate the need to seek new ways of assessing foreign languages through the design of tests that fit in the current digital and interactive world.

Published: October 2021

Undergraduate students are categorized as Generation Z. They prefer learning using video rather than the book. Demonstration videos are suitable for productive courses because they show step by step of product making.  This study aimed to 1) develop a video of pickled fruit production for the Food Preservation Technology course, Universitas Negeri Yogyakarta (UNY), Indonesia and 2) determine the video's feasibility. This study was a research and development (R&D) performed by ten steps, namely information collecting, planning, developing initial products, preliminary field testing, main product revision, main field testing, operational product revision, operational field testing, final product revision, as well as dissemination and implementation. Data analysis was performed descriptively. The video feasibility analysis was conducted by one material expert, one media expert, two teachers, two peer reviewers, four students in one-on-one testing, and 36 students in classroom testing. Based on the feasibility test, the video was declared very feasible as learning media. Text, images, animations, and effects appeared in several parts of the video, making it easier for the students to understand the content. This video can be embedded in the learning management system (LMS) such as Google Classroom, Moodle, and others to facilitate mobile learning, and implemented in a flipped classroom design. Pre-test and post-test were then performed on 29 students in operational field testing. The post-test was significantly higher than the pre-test (p<0.05), so the video was able to improve the students' cognitive skills.

Considérations sur le style joanin dans le décor religieux luso-brésilien du xviiie siècle
Authors: Oliveira Pedrosa Aziz José de
Published: October 2021

Cet article offre un aperçu des recherches sur la sculpture en bois doré et polychrome de style joanin, présente dans des églises et des chapelles luso-brésiliennes du xviiie siècle. Il présente le contexte culturel et artistique favorisé par l’action de dom João V (1689-1750), dont le règne a modifié le panorama de l’art portugais qui, à son tour, a exercé une influence au Brésil. L’analyse de ces aspects permet d’examiner l’ascendance de l’art lusophone sur les décors religieux brésiliens des années 1720 aux années 1760, tout en soulignant les moyens qui peuvent avoir nourri le répertoire formel des œuvres, la caractérisation formelle des pièces conservées ainsi que le nom de certains artistes impliqués dans ces processus. Cette approche fait ainsi naître de nouvelles questions relatives à l’ornementation en bois de style joanin au Brésil, une thématique encore insuffisamment étudiée.

Published: October 2021

The article discusses the advances of biomimetics in imitation of the laws of nature. Everything in nature is perfect. Nature is smart, rational and innovative, that’s why scientists and engineers from all over the world are trying to reproduce natural principles in the laboratory. The use of ideas borrowed from wildlife is called biomimetics. Since Leonardo da Vinci tried to design an airplane that simulates the flight of birds, the biomimetics - the science of using natural attributes, functions, and structures in technical equipment was first spoken about. Many scientists look to nature in the hope of finding solutions to the complex issues that humans face. In this regard, the nature provides many ready-made solutions - we just need to adapt them to specific technical problems.

Published: October 2021

Many of the African antimalarial ethno medicinal plants are good sources of promising antimalarial compounds. The stem bark of Plumeria alba Linn, was evaluated for in vivo chemosuppressive antimalarial activities in order to identify the most active solvent  fraction from which antimalarial constituents can be isolated. The stem-bark of Plumeria alba Linn, family Apocynaceae was   collected, air-dried, powdered, macerated in methanol and the extract concentrated in vacuo. The acute toxicity study was   performed on the extract using Lorke’s method. The extract was thereafter tested for chemosuppressive antiplasmodial activities against Plasmodium berghei berghei NK65- infected mice using Peter’s four-day test at doses 100-800 mg /kg with normal saline (0.2 ml) and chloroquine (10 mg/kg) as negative and positive control drugs respectively. The average percentage parasitaemia, percentage chemosuppression and effective doses (ED50 and ED90), the survival times and percentage survivors elicited in all the  mice were  determined as indices of antimalarial activity. The active extract was  subsequently partitioned successively into n-hexane, dichloromethane, ethyl acetate and butanol. The respective partitioned fractions with the aqueous phase were also tested as above at doses 0-80 mg/kg. All results were  subjected to statistical analysis using ANOVA with Student Newman Keul’s post hoc test. Crude extracts of P. alba gave considerable reduction of percentage parasitaemia up to 200 mg/kg. The percentage  chemosuppression at all doses, were significantly higher (p<0.05) than the negative but lower than the positive control with 200 mg/kg dose showing the highest activity of 65.88 %. The effective doses, ED50 and ED90 were  305.82±9.99 and 389.74± 9.60, respectively. The most active n-hexane partitioned fraction elicited a percentage chemosuppression of 67.75 and a significantly lower (p<0.05) ED50 and ED90 of 31.27±0.85 and 54.80±1.75 mg/kg. The butanol and ethyl acetate partitioned fractions gave significantly higher (p<0.05) survival time value than those of the crude extract, other partition fractions and the positive control, while the n-hexane, dichloromethane and the aqueous, just like chloroquine, gave high percentage survivors. The study concluded that Plumeria alba stem-bark extract was active as an antimalarial drug with its antiplasmodial and the survival time–enhancing activity concentrated in the n-hexane and ethyl acetate with butanol partitioned fractions respectively, thus confirming and justifying its ethnomedical application in malaria.

Biometal coordination bearing active donor atoms of medicinal plant extracts or herbal isolates (phytochemicals) in the recent approach of biomedical sciences is a new and advanced chemotherapeutics for combating antibiotics resistance. Stereochemistry of central metal ions around active plant molecules can give rise to robust solid state 3D metal complexes of antibiotics aiding better biological performance/affinity without any side effect compared with the parent biomolecules (organic ligands). This review therefore focuses on the applications of medicinal plant extracts as antibiotics. Structural systems of metal complexes of flavonoids, curcumins, alkaloids, carotenoids and coumarins from aloe vera, acalypha and henna leaf (AAH) are also described with a view to achieving the rationale for functional bioactive antibiotic drugs

The presence of various bioactive components makes it necessary to analyse plants for their potential to act as a source of useful treatments and cures for many inflammatory, infectious and pathogenic diseases. This study was carried out to determine phytochemicals and in-vitro antioxidant activities of the leaf extracts of Acalypha godseffiana. The leaves of A. godseffiana were collected, dried, pulverized and extracted separately with methanol and water using maceration method. The extract was concentrated in vacuo with rotary evaporator at 40oC. The extracts were subjected to quantitative phytochemical analysis and different anti-oxidant analytical procedures like FRAP, DPPH etc to determine the radical scavenging capabilities. The results of phytochemical analysis estimated the quantities and revealed the presence of alkaloids, flavonoids, tannins, saponins and terpenoids which varied in both extracts. The methanol and aqueous extracts exhibited antioxidant activities with relatively high IC50 (IC50 = 3.67 ìg/ml and 4.42ìg/ml respectively) which accounted for a low free radical-scavenging activity when compared with the reference antioxidant, vitamin C (IC50 = 1.51ìg/ml). The results of the study indicates that A. godseffiana leaf extracts contain secondary metabolites and possesses antioxidant properties.

BuddhistRoadPaper 1.2 "Toward A Typology of Chödrup’s (Tib. Chos Grub, Chin. Facheng 法成) Cursive Handwriting: A Palaeographical Perspective"
Authors: Li Channa
Published: October 2021

In this paper, I focus on the palaeography of a collection of eight Tibetan manuscripts hypothesised to have been written by the same scribal hand. The eight manuscripts—IOL Tib J 217, IOL Tib J 686, IOL Tib J 687, IOL Tib J 625, IOL Tib J 588, IOL Tib J 619, P. T. 770, and P. T. 783v—are closely related, not merely in light of their sophisticated cursive handwriting, but also by virtue of their common textual genre (being summaries or commentaries rather than direct scriptural translations) and thematic content: these Tibetan texts were all based on Chinese sources and attributed to Gö Chödrup (fl. first half of the 9th c., Tib. ’Gos Chos grub, Chin. Wu Facheng 吳法成), either directly or indirectly. Moreover, many manuscripts produced by the imperial Tibetan copying project contain editorial records written in the same hand; these records indicate that Chödrup acted as the final proofreader. Therefore, we can now more confidently attribute this hand to Chödrup himself. By establishing a typology of this handwriting and offering a table of how syllables are written by this hand in the appendix, this paper contributes to a better reading of manuscripts containing this type of script and can potentially provide a benchmark for further recognition of works written in the same hand.

Published: October 2021

A Contabilidade é uma Ciência Social aplicada que busca, através da sua função social, prestar informações sobre as relações das empresas com a sociedade na qual ela está inserida, em um mesmo contexto social. Sendo assim, o objetivo do presente trabalho foi o de identificar o grau em investimentos sociais da Petrobrás em comparativo de intervalo de 5 anos. Para identificar o referido grau, foram utilizados os valores divulgados, pela empresa em investimento social sobre a Receita de Vendas Consolidada e o Lucro Antes do Imposto de Renda e Contribuição Social.  A pesquisa mostrou que não há auditoria das informações. Foram encontradas informações sobre investimentos sociais com a mensuração de tributos incluídos dentro destes valores (excluindo os encargos sociais), prejudicando a apuração do grau em investimentos sociais. A empresa faz investimentos socioambientais, não identificando os valores sociais e os ambientais e realiza também os investimentos ambientais, os investimentos ambientais não foram levados em consideração.

Apendicite é uma das principais causas de dor abdominal e as taxas de diagnósticos falsos positivos variavam de 15-30%. Um sistema de pontuação com alta sensibilidade e especificidade e um número aceitável de apendicectomias negativas faz-se necessário. O escore RIPASA foi desenvolvido na Ásia, e apresentou maior sensibilidade, especificidade e acurácia diagnóstica que a escala Alvorado, especialmente na população asiática. Tendo isso em vista, este estudo teve como objetivo avaliar a eficácia do escore RIPASA no diagnóstico de apendicite aguda. Tratou-se de um estudo transversal realizado no interior do Rio de Janeiro com uma amostra consecutiva de 40 pacientes. Foram incluídos pacientes com suspeita de abdome agudo e excluídos aqueles que apresentavam apendicolito ou plastão da fossa ilíaca direita. A decisão de apendicectomia foi baseada no julgamento clínico do cirurgião. A sensibilidade e a especificidade do escore RIPASA encontrada neste estudo foram de 83% e 71%, respectivamente enquanto nos estudos de Naresh et al, 81% e 85%; e de Regar et al, 94% e 60%. O escore RIPASA mostrou-se eficiente, com resultados equiparáveis aos do oriente. É uma ferramenta útil no auxílio do diagnóstico da apendicite.

O processo de licenciamento ambiental, ferramenta da Avaliação de Impacto Ambiental (AIA), tem se tornado objeto de pesquisas que visam analisar a qualidade dos trabalhos desenvolvidos. Alguns dos objetivos da AIA se resumem em prevenir o meio ambiente das degradações ocasionadas por empreendimentos e sinalizar as mitigações dos impactos ocasionados por empreendimentos com potencial nível de degradação ambiental. A presente pesquisa se propôs a avaliar as questões relacionadas ao meio antrópico do licenciamento ambiental da siderúrgica Vallourec & Sumitomo Tubos do Brasil – VSB, localizada em Jeceaba/Minas Gerais. Para tanto, utilizou-se o Guia para Análise Técnica de Estudos de Impacto Ambiental, proposto por SÁNCHEZ (2008). Essa metodologia, adaptada para o estudo em questão, mostrou-se eficiente, mas sinaliza que o profissional responsável pela utilização deve ter conhecimento prévio sobre a temática em tela. Além disso, o método denuncia outras deficiências provenientes do processo de AIA, pois incita a discussão sobre o tema.
Influência de óxidos no aquecimento micro-ondas de arenitos
Authors: Silveira André , Petri Irineu
Published: October 2021

Na perfuração de poços que contém petróleo, são utilizadas brocas que ao penetrarem na matriz rochosa geram fragmentos, que são conhecidos como cascalho. O cascalho é transportado até a superfície pelo fluido de perfuração que possui baixa biodegrabilidade, fazendo com que seja necessária uma separação para que o cascalho possa ser descartado de forma adequada ao meio ambiente. A secagem via micro-ondas está sendo utilizada para a descontaminação desses cascalhos, pois apresenta alta eficiência de remoção comparada a equipamentos convencionais. O aquecimento micro-ondas é fortemente influenciado pela composição química da matriz rochosa. Sendo assim, neste trabalho foram verificados a influência da presença dos óxidos de ferro, alumínio, manganês e cálcio no aquecimento micro-ondas de um arenito. Os testes foram efetuados em um micro-ondas de bancada adaptado, a fim de se verificar como as variações de composição afetam a cinética de temperatura e taxa de aquecimento. Com base nos resultados obtidos, foi possível identificar que o óxido de ferro possui maior sensibilidade às micro-ondas comparado ao óxido de alumínio, devido ao fato das propriedades eletromagnéticas presente no ferro, acarretando em maior taxa de aquecimento. O óxido de manganês foi o que apresentou maior taxa de aquecimento, porém, foi observado uma anormalidade no aquecimento da amostra após certo tempo de exposição às micro-ondas. Por não absorver de forma adequada às micro-ondas, o óxido de cálcio foi o que apresentou menor taxa de aquecimento em comparação aos demais. Com os resultados obtidos, foi possível também desenvolver uma correlação para prever como cada tipo de óxido estudado comporta ao ser submetido ao aquecimento micro-ondas.

A frequência de sobrepeso e obesidade aumenta exponencialmente a cada ano no mundo todo, tornando-se uma comorbidade altamente prevalente em crianças e adolescentes, sobretudo em países desenvolvidos e emergentes. Diversos estudos têm demonstrado uma importante associação entre a prevalência destas comorbidades em portadores do transtorno do espectro autista (TEA), no entanto, poucos estudos têm se direcionado a crianças e adolescentes portadores deste transtorno. O objetivo deste artigo foi avaliar os principais estudos que foram realizados no período de 2009 a 2019, em relação à frequência de sobrepeso e obesidade neste público no Brasil. Para tanto, foi realizada uma revisão bibliográfica por meio da busca de artigos na Biblioteca Virtual em Saúde (BVS), PubMed e Google Acadêmico. Os descritores utilizados foram “sobrepeso”, “obesidade” e “autismo”. Verificou-se 11 artigos voltados estritamente para o público com TEA, mas apenas 5 analisaram a frequência de sobrepeso e obesidade. Existem muitas inconsistências metodológicas, especialmente no uso do IMC, na amostragem com poucos indivíduos e há a necessidade de incluir grupos de controle nas análises. O total de crianças e adolescentes diagnosticados com autismo em todos os artigos foi de 237 indivíduos, a maioria deles tinha entre 3 e 12 anos e do sexo masculino. Dessa forma, foi possível observar a necessidade da realização de mais estudos e pesquisas direcionados à temática apresentada no país, associados também atuações voltadas para a promoção de saúde e políticas públicas.
