Published: January 2021

IntroductionThere is a lack of data summarizing the current burden of stroke in Ghana. The establishment of data on the current burden, incidence, and mortality of stroke in this country may guide decision-making toward interventions to curb the stroke burden. This protocol aims to describe the methods for a systematic review of the literature on the incidence, prevalence, and mortality of strokes in Ghana.Methods and Design We will perform a comprehensive search strategy of relevant abstracts and articles published from 1st May 2013 to 31st May 2020, related to prevalence or incidence or mortality in Ghana. Relevant articles will be searched from electronic databases including MEDLINE (PubMed), CINAHL (EBSCO), Web of Science, and PsycINFO (EBSCOhost). Full text of eligible studies will be included if they estimated one of the following epidemiological measures: burden, incidence and mortality. Studies that will meet the eligibility criteria will be assess for overall study quality, reliability and risk of bias, using design-specific criteria. We will appraise the included studies' reporting and methodology quality and perform a quantitative summary of reported outcomes where applicable.DiscussionExisting knowledge on the incidence or prevalence, or mortality of strokes in Ghana are limited. This review aims to present relevant information that will inform local policy on cardiovascular diseases and future research. The final report of this protocol, in the form of a scientific paper, will be published in a peer-reviewed journal and findings will be submitted to relevant health authorities. We also plan to update the review in the future to monitor changes and guide health service and policy solutions.Trial registration number: https://doi.org/10.17605/OSF.IO/MW3H8

Authors: Yang Xinwei , Chen Hongyue , Li Pengfei , Wang Xin , Wei Yajing
Published: January 2021

Aiming at the severe vertical and pitching vibration of shearer in actual working conditions, the vertical-pitch coupled dynamics model of shearer with 13 degrees of freedom is established using multi-body dynamics theory. Based on the theories of elasticity, Hertz contact and collision dynamics, the connection stiffness model of traction part with rocker arm in existence of clearance and shearer body, the support stiffness models for the guide shoe and for the smooth shoe and the stiffness characteristics model of the rocker arm were constructed. Taking into account the convergence of solution process and the reliability of results, a modified drum load was proposed as the external excitation of the system and the dynamic characteristics of key parts of shearer under different working conditions were analyzed. The numerical model was validated against the vibration responses of a shearer and its critical components under different operating conditions obtained from a mechanical test.The research results provide theoretical basis for the structure optimization and process parameter optimization of the shearer.
Attitudes, Perceptions of Risk, and Behavior Change of Students During Pandemics: A Systematic Review
Authors: Bakshi Simran , Wasim Aghna , Truong Judy , Majid Umair
Published: January 2021

Students in higher education institutions such as universities are at a unique risk for COVID-19 because learning takes place in a manner that warrants frequent social interaction. This systematic review of 18 studies examined the awareness, risk perception, and health behaviors among students in higher education institutions across 15 high- and low-resource countries. We found that accurate knowledge of the disease varied across different countries. We also found that students were more likely to use informal networks and social media to obtain quick and easy-to-understand information about the infection. However, a “casual” or low risk attitude was prevalent from the start of each pandemic of outbreak. This casual attitude circumscribed the adoption of prevention behaviors. We conclude our paper by using the Information-Motivation-Behavioral Model to recommend how to maximize the impact of the design and delivery of public health interventions in the student population.
Eucalyptus Essential Oil Bioactive Molecules from against SARS-CoV-2 Spike Protein: Insights from Computational Studies
Authors: Sharma Arun Dev , Kaur Inderjeet
Published: January 2021

Background: SARS-CoV-2 (COVID-19), a positive single stranded RNA virus, member of corona virus family, is spreading its tentacles across the world due to lack of drugs at present. Being associated with cough, fever, and respiratory distress, this disease caused more than 15 % mortality worldwide. Due to its vital role in virus replication, Spike (S) protein has recently been regarded as a suitable target for drug design. The present in silico docking study was designed to evaluate the effect of potent 12 bioactive molecules present in essential oils of eucalyptus plant leaves against Spike (S) protein from SARS-CoV-2. Till date there is no work is undertaken on in-silico analysis of these compounds against Spike (S) protein of SARS-CoV-2. In the present study, molecular docking studies were conducted by using Patchdock analysis. Material and methods: Protein Interactions Calculator was used for protein interactions. In-silico absorption, distribution, metabolism, excretion and toxicity (ADMET) profile was also studied. Results: The calculated parameters such as docking score indicated effective binding of all bioactive components especially Toruatone to COVID-19 S-protein. Interactions results indicated that, Spike (S) protein / Toruatone complexes forms hydrogen and hydrophobic interactions. Furthermore, our study also highlights the key finding that the S2 domain of COVID-19 spike glycoprotein potentially interacts with Toruatone. In-silico absorption, distribution, metabolism, excretion and toxicity (ADMET) studies provided guidelines and mechanistic scope for identification of potent anti-COVID 19 drugConclusions: Therefore, essential oil from eucalyptus may represent potential herbal treatment to act as COVID-19 Spike (S) protein inhibitor, a finding which must be validated in Vivo. However, further research is necessary to investigate their potential medicinal use.

Published: January 2021

Brucellosis is a transmissible bacterial zoonotic disease caused by Gram-negative coccobacillus bacteria of the genus Brucella. The disease severely hinders the livestock industry and human health. In several instances, infected animals act as carriers for the cross-species transmission of brucellosis. Social issues, poor husbandry practices, irregularities in the marketing and movement of domestic animals, and lack of coordination between veterinary and human health services are some of the key factors responsible for the transmission and prevalence of Brucellosis. Human contact with infected domestic animals is often the transmission route of Brucellosis infection. Therefore, human brucellosis could be eradicated globally by eradicating animal brucellosis. This review describes the current status of brucellosis and the risk factors of the disease in animals and the human population. In addition, there is a further discussion of the various issues related to the control and prevention of brucellosis in domestic animals and humans.

Evaluation of domestic water measurement error: a case study
Authors: Mendoza Andrés A. , Benavides-Muñoz Holger
Published: January 2021

This study presents a method to determine the operation of the measuring equipment by analyzing the metrological quality and degradation of accuracy, depending on the accumulated volume and the installation time. Different types of counters at three flow rates were tested to assess the evolution of the relative error and to determine the average error curves and rate of deterioration. The volume of apparent losses caused by the inaccuracies of the meters was also calculated. The results of the investigation establish the sub-accounting errors and the annual degradation rate were −15 and −1.88%, respectively for consumption flows below 30 L/h represented by 23% of the subscribers. For flow rates of 120 L/h, the system accounts for a 68% consumption of subscribers and an error of −1.8% and a degradation of −0.14% were recorded. Finally, for consumption flows of 1,500 L/h, the system has accounted for 9% consumption of the subscribers; over-accounting values were obtained generating an average error of 16% and a degradation of 1.68%. It is concluded that the hydrometric district has a sub-accounting error equal to −3.24%, which results in a volume of apparent losses of 1.21 m3/connection/month.

HIGHLIGHT

This paper proposes a methodology that allows determining the operation of the domestic water meter by analyzing the metrological quality and degradation of accuracy, specifically by the statistical calculation of the weighted measurement error, the annual degradation and the volume of apparent losses of the domiciliary meters installed in urban areas, using a hydraulic bench test.

Contribuições do Estudo: Acredita-se que este trabalho traz uma contribuição para um diálogo ativo e contínuo quanto ao uso do Blockchain nos processos de auditoria, bem como o conhecimento de vantagens que essa tecnologia oferece aos profissionais e despertará o interesse de pesquisa sobre o uso da tecnologia Blockchain na auditoria contábil.
Aderência a teoria pecking order pelas firmas brasileiras: uma análise multisetorial
Authors: Thicia Stela Lima Sampaio  , Alan Bandeira Pinheiro  , Rubens Carlos Rodrigues  , Maia Lameu Eva Valéria
Published: January 2021

Objetivo: Esse artigo objetiva analisar, de acordo com a teoria pecking order, a associação do endividamento total, de curto e de longo prazo, das empresas que negociam ações na Brasil Bolsa Balcão (B3), distinguindo-as por segmento de atividade.

Metodologia: A amostra é composta por observações anuais de 177 empresas listadas na B3, no período de 2014-2017. Elaborou-se três modelos econométricos de regressão linear múltipla, cada um com uma variável dependente distinta, testados através do IBM SPSS®. Os modelos foram aplicados na amostra completa, e nos 12 segmentos de atividades das empresas que compõem a amostra.

Resultados: No Brasil segmentos de atividade distintos tem também distintas aderência a teoria pecking order, assim como há setores que não são aderentes a estrutura de capital que prioriza fontes próprias de recursos.  Além disso, percebeu-se que há uma maior aderência a teoria pecking order para dívidas de menor maturidade, indicando que para o longo prazo fontes de financiamento externas são mais utilizadas. Empresas que têm práticas e GC e compliance apresentaram menor aderência a teoria pecking order, e uma associação predominantemente positiva com o endividamento de longo prazo e total.

Contribuições do estudo: Ao se analisar a estrutura de capital deve-se considerar com fator relevante o segmento de atividade da empresa, pois diferentes atividades ensejam diferentes níveis de investimentos, maturidade de dívidas, e fontes de financiamento. Não considerar o fator setor de atuação pode gerar resultados enviesados que não refletem a realidade. As teorias de estrutura de capital não devem ser vistas com opostas, mas sim complementares, e para tanto os modelos econométricos para o endividamento total, de longo prazo e de curto prazo pedem variáveis independentes distintas, que capturem os efeitos temporais de cada um desses índices.
The principles underlying the IFRS and the measurement bases of the elements comprising the financial statements
Authors: Camila Teresa Martucheli  , Antonio Dias Pereira Filho
Published: January 2021

Purpose: This theoretical essay seeks to present concepts, arguments and discussions about the adoption and use of IFRS, focusing on their underlying principles and measurement bases.

Methodology: Literature review with presentation and discussion of arguments from authors who have researched the use of IFRS and its underlying principles and measurement bases.

Results: Principle-based accounting standards are seen by a number of authors as a possible solution to the problem of accounting harmonization. However, another stream of authors states that principle-based accounting standardization, although it may result in higher quality it is less assertive financial reporting, given the existence of subjectivity in the content of financial statements. This fact leads to the conclusion that absolute harmonization of accounting standards would be impossible.

Contributions of the Study: The study proposes notes regarding the discussion on IFRS, which are responsible for increasing the quality of financial statements, while at the same time reducing the reliability of the information produced, in view of the difficulties inherent to the application of the concept of fair value.

Published: January 2021

Flavonoids represent a large diverse group of natural products that are used as a traditional medicine
against various infectious diseases. They possess many biological activities including antimicrobial, antioxidant,
anti-inflammatory, anti-cancer and anti-diabetic activities. Commercially, flavonoids are mainly obtained from
plants, however, several challenges are faced during their extraction. Microorganisms have been known as natural
sources of a wide range of bioactive compounds including flavonoids. Actinobacteria are the most prolific group
of microorganisms for the production of bioactive secondary metabolites, thus facilitating the production of flavonoids.
The screening programs for bioactive compounds revealed the potential application of actinobacteria to
produce flavonoids with interesting biological activities, especially anticancer activities. Since marine actinobacteria
are recognized as a potential source of novel anticancer agents, they are highly expected to be potential
producers of anticancer flavonoids with unusual structures and properties. In this review, we highlight the production
of flavonoids by actinobacteria through classical fermentation, engineering of plant biosynthetic genes in a
recombinant actinobacterium and the de novo biosynthesis approach. Through these approaches, we can control
and improve the production of interesting flavonoids or their derivatives for the treatment of cancer.

The Moluccas' Surviving Aristocracy in Indonesian Politics: Fragmentation and Land-based Political Support
Authors: Dardias Kurniadi Bayu
Published: January 2021

The article demonstrates how the Sultanate of Ternate in the Moluccas has survived in post-authoritarian Indonesian politics by analysing the political performances of the Sultan of Ternate and his immediate family members. The success of Sultan Mudaffar Syah in the political arena has contextualised the literature on land-based political economy, something that has largely been neglected. Combining in-depth interviews, observations, and document study, I argue that the Sultan's political achievements were the result of his transforming Ternate's coastal aristocracy into a land-based one, sidestepping the Basic Agrarian Law (BAL) of 1960 by transferring land management and ownership to indigenous communities while still maintaining economic control. However, his wife and children have failed politically, not only because they are not part of the traditional aristocratic structure (and thus have no control over land) but also because of internal fragmentation.
Political Scandal and Public Figure
Authors: Cendani Arum Sekar , Perbawani Pulung Setiosuci
Published: January 2021

Indonesian society is familiar with the terms 'public figures' and 'celebrities', but the distinction is often not understood properly. The public's interest in content that focuses on entertainment, lifestyles, and gossip, as well as the presence of a media that facilitates such content, makes the process of 'celebrating' common. This process has resulted in the private space of public figures being transformed into objects of public consumption.Scandals are often quite popularly discussed among the public, especially when their subject is a public figure. However, studies of how scandals affect the public and its political behaviour have not been widely documented. In 2018, Indonesian news media began widely covering the divorce of well-known politician Basuki Tjahaja Purnama (BTP/Ahok) from his ex-wife Veronica Tan, and this brought questions of extramarital affairs to the surface in the midst of a heated local election atmosphere. This situation was divisive, and received various public responses. Previous studies have shown that scandals tend to negatively affect popular attitudes towards the politicians involved in them. In Indonesia, scandals have been common, widely recognised by the public, but their effects are never discussed in depth. Therefore, this study, which involved around 400 respondents, seeks to provide an overview of how the Indonesian public responds to politicians involved in scandals and how such scandals affect politicians' electability. The results of this study show that scandals do affect the public's political attitude, but not in the ways suggested by existing studies.
Interlanguage Driven by Bilingual Abstract Lexical Structure
Authors: Wei Longxing
Published: January 2021

This study explores the nature of interlanguage (IL) in terms of bilingual abstract lexical structure and its role in the formulation and development of IL as learners’ developing linguistic system. Adopting the Bilingual Lemma Activation Model (BLAM) (Wei, 2002, 2003), it assumes that IL is a composite developing linguistic system because at different times different linguistic systems are in contact, such as learners’ first language (L1), the developing IL, and the target language (TL), and each contributes different amounts to the developing system of IL. The important claim of this study is that the mental lexicon contains abstract entries, called “lemmas”, which contain pieces of information about particular lexemes, and the bilingual mental lexicon contains language-specific lemmas, which are in contact in IL speech production. The other important claim of this study is that IL is fundamentally driven by bilingual abstract lexical structure, which contains several discrete but interacting subsystems: lexical-conceptual structure, predicate-argument structure, and morphological realization patterns, and such an abstract lexical structure in IL may have different sources, such as those from learners’ L1 and/or the TL. The typical instances of learner errors discussed in this study offer some evidence that IL is a composite developing linguistic system.

The Potential of Noni (Moringa citrifolia) in Lowering Blood Glucose Levels in Diabetes Mellitus Patients
Authors: Putri Dafriani  , Mutiara Karamika  , Siska Sakti Anggraini  , Roza Marlinda
Published: January 2021

Background: Diabetes Mellitus is a chronic metabolic disorder caused by insulin resistance. Noni juice has the potential as herbal medicine which believed to reduce blood glucose levels. This study aims to determine the effect of noni juice on blood sugar levels on diabetic patients. Methods: This study used 16 respondents. They divided two groups, a control group and a treatment group. Each group consists of 8 respondents. The intervention group received 150 ml of noni juice which was given once a day for ten days. Glucose testing was carried out by the glucose-check method. The blood was taken from the respondent's fingertips capillary. The blood glucose levels between the control group and the intervention group were analyzed using independent t-test. Results: The average blood glucose level in the intervention group was 199.88 mg/dl, while the control group was 326.25 mg/dl. The test results of the mean blood glucose levels between the control group and the intervention group had a significant difference with a value of p = 0.003 (p ≤ 0.05). This indicates a significant effect between blood glucose levels in the control group and the intervention group. Conclusion: Noni can reduce blood glucose levels because it contains flavonoid. It has a hypoglycemic effect. Health workers can suggest consuming noni juice to decrease blood glucose in diabetic patients.
Application of a Four-Tier Diagnosis Test for Evaluating Student's Misconception about Blood Classification
Authors: Syarafina Syarafina , Zainul Mustofa
Published: January 2021

Background: A misconception is a form of error in scientific knowledge that is believed to be accurate. As a result, someone who has a misconception of something will reject scientific truth and will hinder the assimilation of new knowledge. The purpose of this study was to identify misconceptions that occur in students regarding the topic of blood classification. Methods: The survey method research was conducted on 97 students scattered in Malang and Tulungagung, Indonesia. The data analysis technique uses coding for categorization into four categories: conceptual understanding, partial understanding, misconception, and not understanding the concept. Results: The results showed that misconceptions occurred in all sub-topics of blood classification. Misconceptions were found in the concept of blood plasma (2.1%), white blood cells (6.2%), thrombocytes (17.5%), and blood classification system (8.2%). Misconceptions occur due to several misunderstandings of students such as red blood cells that play a role in transporting nutrients, haemoglobin only binds oxygen, and difficulty distinguishing between antigens and antibodies in determining blood groups, blood donation, and the impact arising from donations. Conclusion: The existence of misconceptions causes students' mastery of blood classification material to be hampered.

Background: Electric cigarette is a type of cigarette that change the liquid containing nicotine and other ingredients in the form of steam. This research aimed to identify the effect of exposure to e-cigarette smoke towards the thickness of bronchioles mucosa and the alveolar septa on male Balb'C mice (M. musculus). Methods: This research was an experimental design used 24 male divided into four groups, i.e., control dan three treatment groups. Treatment groups were given different volume of e-cigarettes liquid, i.e., 1 ml; 2 ml; and 4 ml. The exposure of e-cigarette was done in 4 weeks, respectively.  Results: Electric cigarette exposure with different fluid volumes leads to an increase in the bronchioles mucosa's thickness and the alveoli septa. Increasing the volume of fluid used results in an increase in bronchioles mucosal thickness, but decreases the alveoli septa's thickness, resulting in destruction and dilatation of the alveoli. Conclusion: Exposure to e-cigarette smoke with a liquid volume of 1 ml affects the increase in the average thickness of the bronchial mucosa and alveoli septa. An increase in the average thickness of the bronchioles mucosa occurs along with increased fluid volume in exposure to e-cigarette smoke.

Background: Gonad differentiation in some teleostei is a critical phase of gonad development. Gonad differentiation in some fish such as the tilapia group is influenced by environmental factors, namely temperature. The aim of this study was to determine the differentiation process of Nilem fish gonads (Osteochilus vittatus) under the influence of temperature. Methods: One day after fertilization (days postfertilization/dpf) fish were exposed to different medium temperature ranges, namely: 28-29 oC, 30-31 oC, 32-33 oC, and room temperature as a control for 35 days. The percentage of fish survival was calculated on the 35th day by calculating the number of surviving fish divided by the total number of fish in 1 tank times 100%. Thirty fish in each treatment were measured for body length at day 10 dpf and day 35 dpf to determine fish growth. Six fish 35 dpf from each treatment were fixed in 70% alcohol for making histological preparations using the paraffin method, Haematoxylin-Eosin staining. Fish survival data growth data in the form of fish length were analyzed using Anova. Gonadal differentiation data were analyzed descriptively. Results: There was no significant difference in the growth of fish in all treatment and control groups. The average survival rate of fish in all treatment and control groups was 100%. Observation of the gonads showed that the gonads were not differentiated in all treatment and control groups. Conclusion: The room temperature range up to 33 oC supports the growth of Nilem fish with gonad development in the indifferent gonad stage.

Entre a Terra e o corpo: a experiência da natureza na obra de Giuseppe Penone
Authors: Cabral Arthur Simões Caetano
Published: January 2021

O presente artigo procura discutir as possibilidades de experiência sensível da natureza suscitadas pelas obras de Giuseppe Penone. Entendida enquanto fenômeno estético, tal experiência pressupõe um contato direto entre o homem e a Terra. O espaço produzido nas obras de Penone, no qual torna-se possível esse contato, é aqui entendido como uma realidade sempre compartilhada, na qual sujeito e objeto confundem-se mutuamente. Nesse sentido, a produção de Penone situa-se a meio caminho entre a Terra – cuja materialidade é, a um só tempo, tema e suporte de expressões artísticas – e o corpo que a esculpe, a decalca, a imagina, a sonha, a experimenta.
Histórias críticas da fotografia nas Amazônias e arte é resistência decolonial
Authors: Leão Cláudia , Tremembé Izabelle Louise Anaúa
Published: January 2021

Este artigo pretende, a partir de relatos e reescritas, pensar sobre percursos das histórias da fotografia nas suas relações entre ética e uso da imagem e apropriação de histórias, na tentativa de repensar a relação de poder constituída a partir de um ponto de vista na história da imagem, partindo da Amazônia paraense como lugar de reflexão. Este texto tem a colaboração de Izabelle Louise Anaúa Tremembé, estudante indígena da Universidade Federal de Ceará (UFC), que fez um relato sobre a cultura da apropriação, da exotificação dos objetos sagrados e sexualização dos corpos femininos, assim como, em sua fala, ela afirma a ausência de conhecimento acerca de seus rituais e, ainda, que a autonomia dos povos indígenas em fazer arte sempre existiu. Os relatos foram articulados no encontro entre professores e produtores de fotografia e cinema em Alcântara/MA, em abril de 2019.

Pescaria Subversiva: um ato de comunicar a r-e-xistência dos povos e comunidades tradicionais do rio Xingu
Authors: Barbosa Ana Laide Soares
Published: January 2021

Por meio da arte de pescar, dos nossos saberes culturais e dos conhecimentos tradicionais, realizamos a Pescaria Subversiva, com o objetivo de defender o rio Xingu contra o complexo hidroelétrico de Belo Monte e visibilizar os(as) pescadores(as) que viviam desse rio. Materializamos a subjetividade simbólica que o rio exercia naqueles que o viam como pai e mãe; o antropocentrismo de mercantilização da natureza; a solidariedade entre os que pescavam; a identificação dos locais tradicionais de pesca; suas delimitações, conflitos socioambientais; e a falta de políticas públicas para os pescadores artesanais. Atualmente o rio está morrendo aos poucos e, com ele, centenas de vidas. Há ameaça de transformar o que restou do seu leito, na vazão reduzida, em polo de mineração.
