Authors: Rohana Rohana
Published: March 2021

The aim of this research is to reveal the deconstruction of male characters in the novel Atheis by Achdiat Karta Mihardja. The method that will be used by researchers in this research is descriptive method. The data collection technique that the writer uses in this research is the content analysis technique. The analysis technique in this research is (1) Identifying the oppositional hierarchy in the text, which usually shows which terms are systematically privileged and which are not. (2) The oppositions are reversed by showing the interdependence between the opposites or their privacy is reversed, and (3) introducing a new term or idea which apparently cannot be included in the old oppositional category. The results showed that ultimately the Atheists believed in God and regretted what they believed so far.

Authors: - Sukristiyonubowo - , Riyanto Damasus
Published: March 2021

The land allocated for newly opened lowland rice can be from ultisols, oxisols, inceptisols, and potential acid sulfate soils. The study was aimed to evaluate nitrogen (N), phosphorous (P), and potassium (K) inputs – outputs of newly developed lowland rice under different treatments and to validate the N, P, and K recommended applications rate according to N, P, and K balances. The study was conducted in Kleseleon village, Malaka District. Five treatments were tested namely T0: farmers practices, T1: NPK at recommendation rate + Rice straw compost, T2: NPK at recommendation rate + Smart + Rice straw compost, T3: ¾ NPK at recommendation rate + Smart + Rice straw compost, and T4: NPK at recommendation rate + Smart + Rice straw compost. The treatments were arranged in a randomized complete block design with three replications. The nutrient balances were constructed according to the difference between nutrient inputs and losses. The results indicated that there were surplus N, P, and K across the treatments and more than adequate to replace N, P, and K removed by harvest products. The suggested N, P, and K application rates were 100 kg urea, 100 kg SP-36, and 100 kg KCl with the addition of compost 3 Mg ha-1 season-1.

Authors: Al-Nofli Mohammed Abdullah
Published: March 2021

The research-teaching nexus is an important factor in the enhancement of the quality of teaching and learning in higher education institutions. The purpose of the study was to explore undergraduate students’ awareness and experiences of research in one faculty at Sohar University, Oman. Data were gathered from 240 undergraduate students using an online survey. Overall, results indicated that while there was good evidence of students’ awareness and experiences of research, less than half of the students in the sample were aware of or had experienced important research activities. Some students reported advantages arising from their participation in research—including developing research skills and gaining new knowledge. They also reported the need for more hands-on research experience and instructor support. Some findings were generally consistent with the literature on students’ awareness and experiences of research. The study provided important implications for the research-teaching nexus at Sohar University.

Authors: Thomas Cynthia M. , McIntosh Constance E. , Bantz Diana
Published: March 2021

The evolution from traditional on campus education to the current distance education modalities using online learning and technology systems have changed how higher education is delivered to thousands of students and faculty. Technology is changing how faculty teach and how students earn higher education degrees. Many students are seeking the flexibility, and independence online distance education offers to earn college degrees often without leaving home. However, some faculty may not be experienced at developing, delivering, and evaluating online distance courses to meet the needs of student learners. This initial paper will guide faculty through a short history of distance learning, the positives and negatives of online learning vs traditional on campus learning, advantages and disadvantages of distance online learning, and the initial considerations for establishing an online course.

Published: March 2021

COVID-19 pandemic obliged thousands of companies pertaining to all economic sectors to undergo the transformation from on-board work to working from home. Along such rush, the probability for companies being hacked incremented many folds. According to VMware cybersecurity strategist Tom Kellermann, quoted in Menn (2020), “There is a digitally historic event occurring in the background of this pandemic, and that is there is a cybercrime pandemic that is occurring” (para 5). In fact, Software and security company VMware Carbon Black declared during April, “that ransomware attacks it monitored jumped 148% in March from the previous month, as governments worldwide curbed movement to slow the spread of the novel corona virus” (Para 4). On the other hand, Anft (2020) reported that “more than 500 educational institutions, including colleges and K-12 schools, faced ransom attacks in 2019” (para 2). This paper uses a descriptive qualitative approach to shed light on the aforementioned subject depending on reported secondary literature about the topic, and offers an analysis to pinpoint weaknesses and barriers, as well as best practices to counterattack the breaches to cybersecurity in organizations. The outcomes serve as an eye opener for security officers in charge of the safety of organizational intellectual properties and stimulates organizations to adopt protection systems and safety practices.
Efficient and Privacy-Preserving Multi-User Outsourced K-Means Clustering
Authors: Li Na , Huang Lianguan , Li Yanling , Sun Meng
Published: March 2021

In recent years, with the development of the Internet, the data on the network presents an outbreak trend. Big data mining aims at obtaining useful information through data processing, such as clustering, clarifying and so on. Clustering is an important branch of big data mining and it is popular because of its simplicity. A new trend for clients who lack of storage and computational resources is to outsource the data and clustering task to the public cloud platforms. However, as datasets used for clustering may contain some sensitive information (e.g., identity information, health information), simply outsourcing them to the cloud platforms can't protect the privacy. So clients tend to encrypt their databases before uploading to the cloud for clustering. In this paper, we focus on privacy protection and efficiency promotion with respect to k-means clustering, and we propose a new privacy-preserving multi-user outsourced k-means clustering algorithm which is based on locality sensitive hashing (LSH). In this algorithm, we use a Paillier cryptosystem encrypting databases, and combine LSH to prune off some unnecessary computations during the clustering. That is, we don't need to compute the Euclidean distances between each data record and each clustering center. Finally, the theoretical and experimental results show that our algorithm is more efficient than most existing privacy-preserving k-means clustering.
Conceptualizing Microfinance Services, Government Regulation and Performance in the Context of Coffee Entrepreneurs: A Theoretical Review
Authors: Juliet Nakabugo Mary , Muathe Stephen , Mwasiaji Evans
Published: March 2021

Microfinance is a poverty reduction gadget since it offers financial assistance to those in need and therefore it is a game plan for uplifting small and medium enterprises. While it has been studied widely in the context of small and medium enterprises, little literature reflects coffee entrepreneurs. This paper, therefore, shows a review of existing theoretical and empirical literature on constructs of microfinance services, government regulations and performance in the context of coffee entrepreneurs. The specific objectives of the study were to discuss the key constructs, establish theories that link these constructs and then recommend a conceptual framework which guides future studies on the highlighted knowledge gaps. The study was anchored on resource-based view supported by, Harrod-Domar model, poverty alleviation and diffusion of innovation theories. The study was a desktop review, and the scores show that studies focused on a direct relationship between microfinance services and small and medium enterprises but did not incorporate coffee entrepreneurs and the moderating effect of government governments. It is therefore recommended that further research should include the context of coffee entrepreneurs to show the effects of microfinance on these entrepreneurs and the moderating variable of government regulations.
Fractional order heat conduction and thermoelastic response of a thermally sensitive rectangular parallelopiped
Authors: SRİNİVAS V. B. , MANTHENA V R , BİKRAM Jaya , KEDAR G. D.
Published: March 2021

In the present paper, the problem of finite dimensional rectangular parallelepiped in isotropic thermoelastic medium with convective type heating is considered. The heat conduction equation (HCE) of the region is described by time HC of fractional order with Caputo derivative form. The non-linear form of heat conduction equation is converted to linear form with Kirchhoff’s transformation. Integral transform technique is used to deal with the spatial variables and Laplace transform technique is used to deal with Caputo type time fractional derivative. Inverse Laplace transform and inverse finite Fourier transform are employed to expose the solution in the transformed domain. Numerical results are obtained for temperature distribution, deflection, stress resultants and thermal stress distribution for different values of time fractional order parameter. These results are presented graphically and discussed for various values of time fractional parameters. The obtained results show significant influence of the time fractional order derivative on the temperature as well as stress distribution. Thermosensitivity plays a vital role in the analysis of any real thermoelastic problems and one should consider their effect while dealing with materials in high temperature environment.
SOLVING THE PROBLEM OF THERMODYNAMIC INEQUALITIES
Authors: ETKİN Valeriy
Published: March 2021

It is shown that the combined equation of the 1st and 2nd principles of classical thermodynamics does not transform into inequality in the case of irreversible processes, if the external energy exchange of the system is expressed in terms of energy carrier flows. This means that thermodynamic inequalities are generated by attempts to take into account the irreversibility of real (non-static) processes, without taking into account explicitly its reasons - the inhomogeneity of the system and the presence of internal sources not only for entropy, but also for other parameters.On this basis, exact expressions of heat and work in open nonequilibrium systems, as well as their dissipative function, are obtained. The physical meaning of entropy as a thermal impulse and the unprovability of the principle of its increase in the framework of equilibrium systems are revealed. Non-entropy criteria for evolution are proposed and the latter is shown to be incompatible not only with the second law of thermodynamics, but also with the laws of conservation of energy carriers. The elimination of thermodynamic inequalities opens up the possibility of applying the equations of thermodynamics, taking into account energy dissipation, to other fundamental disciplines.
Carbon Intensity and the Cost of Equity Capital
Authors: Trinks Arjan , Ibikunle Gbenga , Mulder Machiel , Scholtens Bert
Published: March 2021

The transition from high- to lower-carbon production systems increasingly creates regulatory and market risks for high-emitting firms. We test to what extent equity market investors demand a premium to compensate for such risks and thus might raise firms’ cost of equity capital (CoE). Using data for 1,897 firms spanning 50 countries over the years 2008-2016, we find a distinct and robust positive impact of carbon intensity (carbon emissions per unit of output) on CoE: On average, a standard deviation higher (sector-adjusted) carbon intensity is associated with a CoE premium of 6 (9) basis points or 1.7% (2.6%). This effect is primarily explained by systematic risk factors: high-emitting assets are significantly more sensitive to economy-wide fluctuations than low-emitting ones. The CoE impact of carbon intensity is more pronounced in high-emitting sectors, EU countries, and firms subject to carbon pricing regulation. Our results suggest that carbon emission reduction might serve as a valuable risk mitigation strategy.

Authors: Dobson R. , Siddiqi K. , Ferdous T. , Huque R. , Lesosky M. , Balmes J. , Semple S.
Published: March 2021

BACKGROUND: Scientific understanding of indoor air pollution is predominately based on research carried out in cities in high‐income countries (HICs). Less is known about how pollutant concentrations change over the course of a typical day in cities in low‐ and
middle‐income countries (LMICs).OBJECTIVE: To understand how concentrations of fine particulate matter smaller than 2.5 microns in diameter (PM2.5) change over the course of the day outdoors (across a range of countries) and indoors (using measurements from Dhaka,
Bangladesh).DESIGN: Data on PM2.5 concentrations were gathered from 779 households in Dhaka as part of the MCLASS II (Muslim Communities Learning About Second‐hand Smoke in Bangladesh) project, and compared to outdoor PM2.5 concentrations to determine
the temporal variation in exposure to air pollution. Hourly PM2.5 data from 23 cities in 14 LMICs, as well as London (UK), Paris (France) and New York (NY, USA), were extracted from publicly available sources for comparison.RESULTS: PM2.5 in homes in Dhaka
demonstrated a similar temporal pattern to outdoor measurements, with greater concentrations at night than in the afternoon. This pattern was also evident in 19 of 23 LMIC cities.CONCLUSION: PM2.5 concentrations are greater at night than during the afternoon in homes
in Dhaka. Diurnal variations in PM2.5 in LMICs is substantial and greater than in London, Paris or New York. This has implications for public health community approaches to health effects of air pollution in LMICs.

OBJECTIVE: Interstitial lung diseases (ILDs) are associated with poor prognosis in the intensive care unit (ICU). We aimed to assess factors associated with hospital mortality in ILD patients admitted to the ICU and to investigate long-term outcome.MATERIAL AND METHODS:
This was a retrospective study in a teaching hospital specialised in ILD management. Patients with ILD who were hospitalised in the ICU between 2000 and 2014 were included. Independent predictors of hospital mortality were identified using logistic regression.RESULTS: A total of
196 ILD patients were admitted to the ICU during the study period. Overall hospital mortality was 55%. Two years after ICU admission, 70 (36%) patients were still alive. Of the 196 patients, 108 (55%) required invasive mechanical ventilation, of whom 21 (20%) were discharged alive from hospital.
Acute exacerbation of ILD and multi-organ failure were highly associated with hospital mortality (OR 5.4, 95% CI 1.9–15.5 and OR 12.6, 95% CI 4.9–32.5, respectively).CONCLUSION: Hospital mortality among ILD patients hospitalised in the ICU was high, but even where invasive
mechanical ventilation was required, a substantial number of patients were discharged alive from hospital. Multi-organ failure could lead to major ethical concerns.

BACKGROUND: Approximately 10% of incident TB cases worldwide are attributable to alcohol. However, evidence associating alcohol with unfavorable TB treatment outcomes is weak.METHODS: We prospectively evaluated men (≥18 years) with pulmonary TB in India for up to
24 months to investigate the association between alcohol use and treatment outcomes. Unhealthy alcohol use was defined as a score of ≥4 on the Alcohol Use Disorders Identification Test-Concise (AUDIT-C) scale at entry. Unfavorable TB treatment outcomes included failure, recurrence, and
all-cause mortality, analyzed as composite and independent endpoints.RESULTS: Among 751 men, we identified unhealthy alcohol use in 302 (40%). Median age was 39 years (IQR 28–50); 415 (55%) were underweight (defined as a body mass index [BMI] <18.5 kg/m2); and
198 (26%) experienced an unfavorable outcome. Unhealthy alcohol use was an independent risk factor for the composite unfavorable outcome (adjusted incidence rate ratio [aIRR] 1.47, 95% CI 1.05–2.06; P = 0.03) and death (aIRR 1.90, 95% CI 1.08–3.34; P = 0.03), specifically.
We found significant interaction between AUDIT-C and BMI; underweight men with unhealthy alcohol use had increased risk of unfavorable outcomes (aIRR 2.22, 95% CI 1.44–3.44; P < 0.001) compared to men with BMI ≥18.5 kg/m2 and AUDIT-C <4.CONCLUSION:
Unhealthy alcohol use was independently associated with unfavorable TB treatment outcomes, highlighting the need for integrating effective alcohol interventions into TB care.
Integrando Bases Autônomas Externas no Processamento de Consultas em Bases RDF Distribuídas
Authors: Takiuchi Hugo Paulino Bonfim , Penteado Raqueline Ritter de Moura , Hara Carmem Satie
Published: March 2021

No modelo RDF, uma consulta pode envolver tanto dados armazenados em bases autônomas de terceiros e acessados através de endpoints SPARQL, bem como dados armazenados em uma base proprietária. Sistemas federados processam esse tipo de consulta acessando as bases externa e proprietária como caixas-pretas. Um moderador envia subconsultas para as bases, que retornam os resultados das requisições. Por outro lado, um sistema RDF tradicional não acessa bases externas, mas utiliza sua base proprietária como caixa-branca, o que permite otimizações nas estratégias de processamento interno do sistema. Este artigo propõe uma alternativa a arquitetura federada, chamada de FeSHyD, que explora uma base proprietária distribuída, permitindo a comunicação dos seus servidores com bases de terceiros durante o processamento de consultas. A proposta promove o processamento paralelo de consultas na base proprietária, descentralizando a tarefa do moderador dos sistemas federados. Experimentos iniciais mostraram que o FeSHyD pode reduzir o tempo de resposta de consultas quando comparado com sistemas federados.
A Framework for Set Similarity Join on Multi-Attribute Data
Authors: Ribeiro Leonardo Andrade , Borges Felipe Ferreira , Oliveira Diego Junior do Carmo
Published: March 2021

Set similarity join, which finds all pairs of similar sets in a collection, plays an important role in data cleaning and integration. Many algorithms have been proposed to efficiently answer set similarity join on single-attribute data. However, real-world data often contain multiple attributes. In this paper, we propose a framework to enhance existing algorithms with additional filters for dealing with multi-attribute data. We then present a simple, yet effective filter based on lightweight indexes, for which exact and probabilistic implementation alternatives are evaluated. Finally, we devise a cost model to identify the best attribute ordering to reduce processing time. Our experimental results show that our approach is effective and significantly outperforms previous work.

Published: March 2021

Um problema essencial no pré-processamento de dados está relacionado a lidar com dados ausentes. Uma possível solução para esse problema é a imputação hot-deck, uma técnica composta de duas etapas: primeiro agrupar registros semelhantes no conjunto de dados de entrada e, em seguida, realizar a imputação em cada grupo separado. No entanto, selecionar o melhor algoritmo para a segunda etapa é uma tarefa desafiadora. Este artigo apresenta um estudo comparativo da imputação hot-deck considerando dois métodos de comitê: Bagging e Adaboost. Avaliamos esses métodos usando conjuntos de dados com diferentes correlações entre seus atributos, variando as taxas de valor ausente. Nossos resultados medindo a precisão dos dados imputados por ambas as técnicas indicam que o Adaboost resulta em melhor precisão e tempo de processamento razoável.

Published: March 2021

O tempo de duração do ciclo de vida no aprendizado por meio de redes neurais profundas depende do acerto em decisões de configuração de dados que levem ao sucesso na obtenção de modelos. A análise de hiperparâmetros e dados da evolução da rede permite adaptações que diminuem o tempo de duração do ciclo de vida. No entanto, há desafios não apenas na coleta de hiperparâmetros, mas também na modelagem dos relacionamentos entre esses dados. Este trabalho apresenta uma abordagem centrada em dados de proveniência para enfrentar esses desafios, propondo uma coleta com flexibilidade na escolha e representação de dados a serem analisados. Experimentos com a abordagem junto ao Keras, usando uma aplicação real com uma rede neural convolucional, dão evidências da flexibilidade, eficiência da coleta de dados, análise e validação dos dados da rede.

Authors: Yahyaie Maryam , Morovati-Sharifabad Majid , Salehi Elham , Sarkargar Fatemeh , Pourghanbari Gholamhosein
Published: March 2021

Background: Ovarian cancer is the second leading cause of death in Iran compared with other gynecological diseases. Considering the role of cyclooxygenase (COX) enzymes and prostaglandin E2 production in tumor lesions, nonsteroidal anti-inflammatory drugs (NSAIDs) show antitumor properties by inhibiting COX. Furthermore, some compounds can serve as non-selective inhibitors of COX (such as ketoprofen) and prevent cancer development. Human epididymis protein 4 (HE4) is one of the most sensitive tumor markers known in the study of the disease of ovarian epithelial cancer. The expression of HE4 increases in different types of ovarian cancer. Objectives: The aim of this study was to determine the anti-cancer effects of ketoprofen on the viability of ovarian cancer cells and expression of HE4 gene. Methods: To calculate half-maximal inhibitory concentration (IC50), A2780S cells were treated with different concentrations of ketoprofen for 24 hours, then the cells were incubated with appropriate concentrations of IC50 for 24, 48, and 72 hours. Real-time polymerase chain reaction (PCR) was used to measure changes caused by the effect of drugs on HE4 gene expression and analyzed by the 2-ΔΔCT method. Results: The IC50 level of ketoprofen for 24 hours was 583.7 μM. According to real-time PCR results, treatment of cells with ketoprofen reduced HE4 expression. Conclusions: HE4 gene expression decreased in cells treated with ketoprofen compared with the cells in the control group, which proves the anti-cancer activity of ketoprofen and a reduction in the viability of ovarian cancer cells.
Expression and Functional Assessment of Some Featured Coding and Non-coding RNAs Encoded by 8q24 Chromosomal Region in CML Patients
Authors: Zamani Mina , Galehdari Hamid , Bakhshinejad Babak , Hajjari Mohammad-Reza , Foroughmand Ali-Mohammad
Published: March 2021

Background: The association between the human chromosomal 8q24 region and cancer development remains dim. The proto-oncogene MYC is known as the most prominent target of this chromosomal region. However, numerous cancer-associated genetic alterations in the region extend beyond the MYC locus. Accordingly, it is likely that the MYC oncogene is not the only target of these carcinogenesis-related alterations. Objectives: In the present study, the expression of MYC and the correlation between MYC and two non-coding RNAs, namely PVT1 (circular and linear forms) and CASC11, which are residents of the 8q24 region in the MYC neighborhood, were investigated in chronic myeloid leukemia (CML). Methods: Real-time polymerase chain reaction (PCR) was used to assess BCR-ABL transcripts and categorize positive and negative (normal) samples for CML. Afterward, real-time PCR was exploited to evaluate the expression of different genes, including MYC, linear PVT1, circular PVT (CircPVT1), CASC11, and ACTB in CML and normal samples. Results: We found that the expression of linear PVT1 is significantly increased in CML compared with normal samples. However, CircPVT1, CASC11, and MYC did not show significantly altered expression between CML and normal groups. The experimental and in silico analyses of the correlation coefficients of gene expressions suggested changes in the correlations between the gene expressions in CML compared with normal samples. We also assessed the miR-trapping potential of PVT1 and CASC11 and the possible effects of these interactions on signaling pathways. Our findings indicated that these lncRNAs could have a possible regulatory link with critical pathways associated with leukemogenesis. Conclusions: Our results indicate that non-coding genes surrounding MYC within the 8q24 region might have regulatory roles in CML carcinogenesis.

This evaluation was targeted at providing the first evaluation of analgesics declared on Doping Control Forms (DCF) from football players in the highest German leagues, the Cup, and the A and B Juniors’ Bundesliga. Methods: The evaluation included a total of 8,344 DCF from doping controls performed by the National Anti Doping Agency Germany in the five football seasons from 2015/16 to 2019/20. This included both in-competition and out-of-competition doping controls in the Bundesliga, 2nd Bundesliga, 3rd League, Women’s Bundesliga, A and B Juniors’ Bundesliga, and the Cup. Results: On average, 33% of all DCF from the last five seasons of the adult and junior sector of the top football leagues in Germany declared use of analgesics within the seven days preceding testing. The A and B Juniors’ Bundesliga has significantly lower values, at an average of 14% ibuprofen was the most commonly reported among 14 analgesic active substances, across all leagues and seasons. Discussion: Some of the analgesic active substances recorded are used for self-medication, while others are prescription drugs. They are not considered doping substances under the current rules of the World Anti-Doping Agency (WADA). However, the calculated frequency of their use suggests that further scientific surveys in competitive sport should be initiated, e.g. via the WADA Monitoring Program. Since analgesics have a general potential for abuse, continuous information of athletes, supported by the sports environment, concerning the deliberate use of such medications is required.

O estudo teve como objetivo avaliar a acurácia de modelos mistos não lineares na projeção do crescimento em diâmetro de árvores individuais de Hevea brasiliensis. A área de estudo está localizada no município de Linhares, Espírito Santo e possui área total de 784 m². As árvores estão plantadas no espaçamento de 2,0 x 2,0 m. As medições do diâmetro a 1,3 m do solo das árvores foram realizadas anualmente dos dois aos 14 anos de idade. Foram ajustados três modelos não lineares considerando efeitos fixos e efeitos aleatórios, sendo estes os modelos de Pienaar e Schiver, Mitscherlich e Chapman-Richards. A avaliação das estimativas geradas pelos modelos mistos e fixos foi realizada, tanto para o ajuste como para a projeção, com base no coeficiente de correlação (r), viés [V (%)], relative root mean square error [RMSE(%)]. O desempenho dos modelos de regressão quando considerado também efeitos aleatórios foi superior aos modelos de efeito fixo, sendo capaz de modelar a heterocedasticidade e a autocorrelação observada na análise gráfica dos ajustes dos modelos com efeito fixo.  O RMSE mais baixo dos modelos de efeito fixo foi 4,53% e para o efeito misto foi 3,71%. Quando comparado o valor de RMSE da projeção, o menor valor obtido com o modelo de efeito fixo foi de 22% e com efeito misto de 4,38%. A utilização de modelos de efeitos fixos e aleatórios resultou em ganhos significativos de acurácia, boa aplicação em dados agrupados e permitiu modelar a heterocedasticidade e a autocorrelação dos dados.

O Vale do Taquari é uma região do estado do Rio Grande do Sul cuja produção de leite é uma das principais atividades econômicas desenvolvidas por pequenos produtores familiares em cooperação com empresas de laticínios, cuja renda com sua comercialização pode variar, pois recebe conforme qualidade do produto. Assim, o produtor vê a lavoura de grãos como complementação da renda, sendo que o método de plantio no RS é de monocultura, utilizando-se agrotóxicos para manutenção dos plantios, prática insustentável. O Sistema Agroflorestal (SAF) vem como uma proposta de manejo sustentável, podendo ser aplicado em áreas de Reserva Legal (RL), gerando-se renda em local não visualizado pelo produtor como rentável. Contudo, o objetivo do estudo é propor modelo de SAF na área de RL de uma propriedade produtora de leite no Vale do Taquari/RS. O método utilizado consiste em um roteiro de entrevistas com o produtor, análise de fertilidade do solo da RL, estudo florístico e conferência em bibliografias de cultivares adequados à área. Analisou-se que a área de RL possui um solo levemente ácido devido à predominância de K no solo, necessitando equilibrar com as substâncias básicas Ca e Mg em todas as Células Amostrais (CAs). Dos demais parâmetros de fertilidade, somente Fe não foi detectado. Para tanto, foram selecionadas espécies para adubação verde para recompor os nutrientes no solo, ao mesmo tempo que podem reduzir sua acidez. Foi observado que 29,5% das espécies registradas na RL possuíam potencial agroflorestal com comercialização de frutos, sementes e outras partes botânicas. Para manter a originalidade da floresta, foram selecionadas as frutíferas nativas cereja, guabiroba e morango-silvestre, bem como frutíferas exóticas mirtilo e fisális, para compor o SAF em RL. Para a área de possível expansão do SAF, foram selecionadas frutíferas nativas, espécies propostas pelo produtor rural (erva-mate, abacate e noz pecã) e hortaliças, além de espécie melífera para atrair polinizadores. Conclui-se que é possível realizar o manejo sustentável em área de RL por meio de SAF, onde este estudo pode mostrar à região uma nova forma de produção, além de oferecer à comunidade um produto diferenciado, sem uso de agrotóxicos, que preserva o meio ambiente e promove a qualidade de vida

O objetivo deste estudo foi identificar os principais distúrbios fisiológicos, relacionados às atividade laboral de trabalhadores expostos aos compostos BTEX (Benzeno, Tolueno, Etil Benzeno e Xileno) e os danos genéticos causados em função do grau de exposição, assim como,  a intercorrelação desses, com  as características sociodemográficas dos trabalhadores de postos de combustíveis de Ji-Paraná/RO. O estudo foi realizado com um grupo de 120 voluntários, sendo formado por 80 trabalhadores de postos de combustíveis e 40 indivíduos que não executam a mesma função, considerados como grupo controle. As características sociodemográficas dos indivíduos do estudo foram obtidas por meio da aplicação de um questionário semiestruturado. Após, esses, foram divididos em 3 grupos para a coleta de amostras da mucosa oral e análise citológica. O grupo 1 (GE1) composto por 40 trabalhadores expostos aos BTEX e usuários de bebida alcoólica e tabagistas; o grupo 2 (GE2) formado por indivíduos exposto, com igual número de trabalhadores, e não usuários de bebidas alcoólicas e tabagista. Esses grupos também foram subdivido por idade. O grupo três (GC) foi considerado como testemunha. Os resultado das análises citológicas da presença de micronúcleos e anormalidades celulares (cariorréxe, binucleação, brotamento e apoptose), demonstram que os indivíduos dos grupos expostos apresentam maior prevalência de danos genéticos e anormalidades celulares em comparação ao grupo controle, além de que, os indivíduos de faixa etária entre 26 à 55 anos apresentaram maior frequência de micronucleos. Observou-se ainda que quanto maior for o tempo de exposição aos combustíveis, maior é a incidência dos sinais clínicos e danos genéticos as células da mucosa oral.
visiting the Roman Iron Age Hoby chieftain burial after 100 years of its discovery - adding the strontium isotopic perspective
Authors: Frei Karin Margarita , Klingenberg Susanne
Published: March 2021

In 1920 on the island of Lolland, in southern Denmark the remains of one of northern Europe’s richest graves came to light, the Hoby chieftain burial. It revealed a large number of luxurious Roman goods, including two silver drinking cups decorated with Greek-inspired scenes from Homer’s Iliad. The burial dates to the beginning of the Roman Iron Age (1CE -200CE), and represents a key point in time when the Roman Empire failed to expand towards the north and changed its strategy towards a more political and diplomatic type of relationship with northern Europe. Hence, the Hoby burial is considered to be a key example of this type of relationship. We revisited the burial and present the first strontium isotope analyses of the human remains of the Hoby individual from three of his teeth and 10 additional environmental samples to shed light on his provenance. We discussed these results in light of the new insights provided by recent excavations of a contemporary nearby settlement. Our results indicate that the Hoby individual was most probably of local origin, corroborating previous interpretations. Furthermore, the associated settlement seems to confirm the central role of Hoby in the Early Roman Iron Age society.
Exploring radiation measurement after Fukushima: When media ecology meets citizen science
Authors: Abe Yasuhito
Published: March 2021

While various scholars have investigated the role of citizens in generating scientific data after the Fukushima Daiichi nuclear disaster under the labels of citizen science and citizen sensing, this essay draws on media ecology and explores its potential theoretical usefulness for enhancing our understanding of post-Fukushima citizen science practices. Taking Marshall McLuhan’s perspective of technology as a medium, this article creates a theoretical framework for foregrounding the role of a measurement device (of radiation levels, in this case) in extending its user’s body and mind. In doing so, this essay attempts to contribute to the fields of media studies and Science, Technology, and Society (STS).
Twitter y programas de televisión: una relación imperfecta
Authors: San Cornelio Gemma
Published: March 2021

Hace algunos meses que observo con cierta curiosidad el uso de Twitter que hacen los programas de televisión, tratando de entender hasta qué punto la relación con la red social de algún modo puede influir en términos positivos, negativos, o simplemente neutros, no sólo a la construcción de las audiencias, sino a los contenidos o dinámicas de los mismos. La forma en que se ha introducido esta herramienta en los programas de televisión es bastante variada: desde la publicación de comentarios en directo, sustituyendo claramente los SMS, hasta la elaboración de elementos narrativos.

Although sprains of the hallux metatarsophalangeal (MTP) joint ligaments occur in barefooted martial arts athletes, few studies discuss the surgical treatments for lateral collateral ligament damage. We report herein a case of lateral collateral ligament repair for chronic hallux MTP joint instability. A 21-year-old male collegiate sumo wrestler injured his left hallux by snagging it on a sumo straw bale at 14 years of age. After entering university (4 years after the injury), he could no longer put weight on his foot at the left hallux; his athletic performance deteriorated, and he was referred to our department by his doctor. He had instability in the MTP joint of the left hallux, and magnetic resonance imaging revealed a tear in the attachment of the lateral collateral ligament to the metatarsal bone. Conservative treatment, such as taping, did not improve the symptoms; thus, surgery was performed, which consisted of passing a strong suture attached to the capsular ligament through a burr hole made in the metatarsal bone and fixing it to the burr-hole wall using an anchor. Postoperatively, the patient's joint instability improved, and he returned to competitive wrestling 4 months after surgery. He was able to put weight on his left hallux, and his athletic performance improved. The follow-up period after surgery was 2 years. In competitive sumo wrestling, hallux weakness and joint instability lead to a significant reduction in performance. Thus, ligament repair is an effective treatment for hallux MTP joint instability that cannot be treated by conservative means.
