Efficient join algorithms for large database tables in a multi-GPU environment
Authors: Rui Ran , Li Hao , Tu Yi-Cheng
Published: February 2021

Relational join processing is one of the core functionalities in database management systems. It has been demonstrated that GPUs as a general-purpose parallel computing platform is very promising in processing relational joins. However, join algorithms often need to handle very large input data, which is an issue that was not sufficiently addressed in existing work. Besides, as more and more desktop and workstation platforms support multi-GPU environment, the combined computing capability of multiple GPUs can easily achieve that of a computing cluster. It is worth exploring how join processing would benefit from the adaptation of multiple GPUs. We identify the low rate and complex patterns of data transfer among the CPU and GPUs as the main challenges in designing efficient algorithms for large table joins. To overcome such challenges, we propose three distinctive designs of multi-GPU join algorithms, namely, the nested loop, global sort-merge and hybrid joins for large table joins with different join conditions. Extensive experiments running on multiple databases and two different hardware configurations demonstrate high scalability of our algorithms over data size and significant performance boost brought by the use of multiple GPUs. Furthermore, our algorithms achieve much better performance as compared to existing join algorithms, with a speedup up to 25X and 2.8X over best known code developed for multi-core CPUs and GPUs respectively.
Generalized almost even-Clifford manifolds and their twistor spaces
Authors: Hernández-Moguel Luis Fernando , Herrera Rafael
Published: February 2021

Motivated by the recent interest in even-Clifford structures and in generalized complex and quaternionic geometries, we introduce the notion of generalized almost even-Clifford structure. We generalize the Arizmendi-Hadfield twistor space construction on even-Clifford manifolds to this setting and show that such a twistor space admits a generalized complex structure under certain conditions.
Design and development of rigid coaxial line based variable stub tuner
Authors: Jain Abhinav , Yadav Rana Pratap
Published: February 2021

This paper presents a novel design of rigid coaxial line based variable stub tuner. It incorporates controlled drive for the movement of shorting ring along the length of the stub inside the coaxial line. The ring is housed inside stub through linear slot over the coaxial conductor. Inbuilt slot at outer conductor of coaxial line introduces undesirable discontinuity which deteriorates the performance of the stub. It needs to be compensated to get the desirable performance of tuner. The effect of discontinuity has been analyzed using circuit modelling and compensated in design itself for the desired performance. The compensated tuner has been fabricated and tested where test results are found as return loss better than 25 dB and Voltage Standing Wave Ratio (VSWR) in between 1.1 and 1.9 in the frequency range of 80–850 MHz. The presented work is useful for the development of high power stub tuner in the range of High Frequency (HF), Very High Frequency (VHF) and Ultra High Frequency (UHF) which is an interest of wide spread applications in areas of communication, defence, satellite, radar, tokamak etc.

Authors: Loochi Shiran Abargil , Demol Sharon , Nagelberg Nessia , Lebenthal Yael , Phillip Moshe , Yackobovitch-Gavan Michal
Published: February 2021

Background

The impact of gonadotropin-releasing-hormone-analogue (GnRHa) treatment on weight and body composition is controversial. Exploring the nutritional, psychological patterns of this population may aid to clarify this propensity to gain weight. This prospective observational study aimed to evaluate longitudinal changes in adiposity, nutrition and quality of life in girls with central precocious/early-fast puberty (CPP/EFP) during GnRHa treatment.

Methods

Thirty-two GnRHa-treated girls with CPP/EFP and 27 prepubertal girls (7–10 years) were included in the analysis. Outcome measures assessed at baseline for CPP/EFP and the control groups and during up to two years of GnRHa treatment for the CPP/EFP group, included anthropometrics, body-composition, basal-metabolic-rate (BMR), 3-day food-diaries, child eating-behavior questionnaire, and pediatric quality-of-life questionnaire (PedsQL).

Results

Girls with CPP/EFP had higher pretreatment BMI-SDS, fat percentages, waist circumference and waist-per-height (p<0.01 for all), and lower psychosocial functioning than controls (p<0.05). Changes in anthropometric and body composition measurements indicated a gradual increase in adiposity and a decrease in muscle mass (p<0.001 for all). Dynamics in body composition could not be explained by the participants’ self-reported dietary patterns and physical activity levels or by the measured BMR, which revealed an adequate and relatively low energy intake as compared to energy requirements. A gradual decline in physical functioning (PedsQL) after one and two years of GnRHa treatment was observed (p<0.001).

Conclusions

Our findings highlight the need for comprehensive surveillance in girls with CPP/EFP. Dynamics in weight status and body composition during GnRHa treatment indicate the need for tailored nutritional and physical activity counseling aimed at preventing obesity.

This is an attempt to showcase the most important events that happened while the polish troops were stationed in town and were still trying to provide peace and safety it and its people.
Time-varying threshold cointegration with an application to the Fisher hypothesis
Authors: Yang Lixiong
Published: February 2021

This paper extends the threshold cointegration model developed by Gonzalo, J., and J. Y. Pitarakis. 2006. “Threshold Effects in Cointegrating Relationships.” Oxford Bulletin of Economics & Statistics 68: 813–33 and Chen, H. 2015. “Robust Estimation and Inference for Threshold Models with Integrated Regressors.” Econometric Theory 31 (4): 778–810 to allow for a time-varying threshold, which is a function of candidate variables that affect the separation of regimes. We derive the asymptotic distribution of the proposed least-square estimator of the threshold, and study the convergence rate of the threshold estimator. We also suggest test statistics for threshold effect and threshold constancy. Monte Carlo simulations point out that the convergence rate of the threshold estimator is consistent with the asymptotic theory, and the proposed tests have good size and power properties. The empirical usefulness of the proposed model is illustrated by an application to the US data to investigate the Fisher hypothesis.
The PROMISE Model: An English-Learner Focused Approach to School Reform
Authors: Olsen Laurie
Published: February 2021

Findings from a 3-year (2006-2009) evaluation of the PROMISE Model pilot are presented in this policy brief that seeks to address three questions: 1) What is the PROMISE Model ?; 2) What changes occurred in schools as a results of implementing the PROMISE Model ?; and 3) What are the lessons learned from the PROMISE Model pilot that can contribute to an understanding of school reform for English Learners? A qualitative, ethnographic approach allowed for exploration of the research questions. The researcher identified five foundational elements to the PROMISE Model. Implementation of the PROMISE Model increased use of EL specific research-based approaches to student grouping, placement, instruction, school structures, curriculum choices, program design and practices in addition to more knowledgeable and advocacy-oriented leaders and distributive leadership. The brief presents five lessons learned that contribute to a deeper understanding of the impact of a school reform model on English Learners. Two policy recommendations include: 1) broadly disseminate research on effective EL education and provide an infrastructure of support with EL expertise; and 2) adopt the PROMISE Model or components of the model as a viable school improvement strategy.
ENTREPRENEURSHIP COMPETENCE FOR SOCIETY AND SCHOOLS IN TIME OF CRISIS. A SYSTEMATIC BIBLIOGRAPHIC REVIEW
Authors: Castellote López Cristina , Caballero García Presentación Ángeles
Published: February 2021

Entrepreneurship education plays an essential role in the development of countries. The purpose of this study is to conduct a systematic review of the literature to encourage Spanish education to organize more entrepreneurship proposals in schools that can reinforce the country after the coronavirus crisis. This competence's value lies in its perception as a strategy that engages actions to achieve social advantages. The databases used were Google Scholar, WOS, SCOPUS, Dialnet and Redalyc. After applying eligibility criteria and eliminating duplicates, 30 articles were selected, which are the main basis for the treatment of business competence and the proposal of an intervention for secondary school students, which aim to generate entrepreneurship competences among them, that improve their employability and their coping in crisis situations derived from health pandemics such as those we have recently experienced due to the coronavirus. The results are discussed by the positive impact of the work of this competence in the society and in the education of the students. In addition, the research offers a reflection on the feasibility of the proposal in the future.
Translation of Character Names in Le avventure di Pinocchio by Carlo Collodi
Authors: Lukančenko Brigita , Klioštoraitytė Rasa
Published: February 2021

Translating character names in fiction can be difficult, as names can perform different functions: not only naming, but also highlighting characteristic features. Translators of fiction have to make certain decisions how to render names in the Target Text and retain the functions and meanings they serve in the Source Text. The aim of this article is to analyse the translation of character names in C. Collodi’s Le avventure di Pinocchio into Lithuanian, Polish and Russian and to compare the translation startegies chosen by the translators. The results of this analysis show that the most common rendering method in the Lithuanian, Polish and Russian versions was direct translation. Also, it can be concluded that character names were rendered most accurately in their translation into Lithuanian, the second in terms of accuracy of rendering character names is the translation into Russian, and the third – into Polish.
Designation of the General Concept of Compensation for Work in English and Lithuanian
Authors: Tekoriūtė Aušra
Published: February 2021

As part of a systematic knowledge-based analysis of terms related to regulation of wages, the paper analyzes the meaning, usage, and translation of terms designating the general concept of compensation for work in English and Lithuanian. The analysis is based mainly on Chapter IX of the Labour Code of the Republic of Lithuania and its translation into English, as well as the translation of conventions of the International Labour Organization (ILO) and some other legal texts related to wages into Lithuanian. It has been established that while some English and Lithuanian terms with the general meaning of compensation for work are very similar both semantically and functionally, it is possible to trace certain smaller or greater differences between them.
Unexpected Laureate: Louise Glück in Lithuania
Authors: Užgiris Rimas
Published: February 2021

The aim of this paper is to give an overview of the work of the American poet, Louise Glück, winner of the 2020 Nobel Prize in Literature, with a discussion of what kinds of challenges her poetry might pose for translators. Very few people knew of her work in Lithuania prior to the Nobel Committee’s announcement. Her poems were only published in Lithuanian translation for the first time in July, 2020, and only a handful at that. This paper argues that her work has important similarities and differences to Lithuanian poetry of the twentieth century, and that despite her free-verse lyrics written in rather plain diction, there are still many challenges to rendering her work in another language. The Lithuanian translations reveal stumbling points over ambivalent word choices, surreal imagery caused by ambiguous syntax, and the need for careful attention to the tone of the narrative voice (the lyrical subject) of the poems.
Latvian Translation Scene at the Turn of the 19th and 20th Century
Authors: Veisbergs Andrejs
Published: February 2021

The paper looks at the Latvian translation scene at the end of the 19th and the beginning of the 20th century. It is a continuation of the study of translation history in Latvia reflected in previous issues of Vertimo studijos (vol. 7, 8, 11). These decades are marked by a huge growth of translation, especially in periodicals. German was gradually losing its dominant position as a source and intermediate language, Russian was advancing, so was also the scope of other languages. In contrast to previous periods there was a particular interest in the quality of the originals and modernity.This period also saw a change of generations among translators, and women became visible in translation scene. Translators among whom there were all the great Latvian writers gradually emerged as professionals. Frequently translations had prefaces and explanations by the translators. There were numerous parallel translations of the same works, some reaching up to ten versions. Translations included various genres and the traditional Latvian interest in plays was very obvious. So was the focus on specialised literature on agriculture. The translation method changed from localisation to a fidelity mode with a tendency to apply elements of foreignisation.
Nonlinearity of Competition-Stability Nexus: Evidence from Bangladesh
Authors: Dutta Kumar Debasis , Saha Mallika
Published: February 2021

Financial deregulation since the 1980s has been stimulating fierce competition among banks and influencing financial stability across the world. In pace with this, Bangladesh's banking industry is also experiencing intense competition since it is composed of many banks. The empirical evidence on competition and stability widely debate to date, perhaps for not considering the potential nonlinearity. Therefore, our study aims to explore the nonlinear impact of competition on the financial stability of Bangladeshi banks over 2010-2017. For achieving this objective, we compute the Boone indicator and Z-score using bank-level data to measure competition and stability, respectively, and examine the nonlinear dynamics of competition-stability nexus employing threshold analysis in a panel setup. Our findings confirm that the competition-stability relationship is nonlinear and implies that financial stability is more substantial (weaker) in a less (more) competitive market. Our results bear specific policy implications.JEL Classification: G21, G28How to Cite:Dutta, K. D., & Saha, M. (2021). Nonlinearity of Competition-Stability Nexus: Evidence from Bangladesh.

Increasing use of social media by patients and clinicians creates opportunities as well as dilemmas for pediatricians, who must recognize the inherent ethical and legal complexity of these communication platforms and maintain professionalism in all contexts. Social media can be a useful tool in the practice of medicine by educating both physicians and patients, expanding access to health care, identifying high-risk behaviors, contributing to research, promoting networking and online support, enhancing advocacy, and nurturing professional compassion. At the same time, there are confidentiality, privacy, professionalism, and boundary issues that need to be considered whenever potential interactions occur between physicians and patients via social media. This clinical report is designed to assist pediatricians in identifying and navigating ethical issues to harness the opportunities and avoid the pitfalls of social media.

Aim of the study: In this retrospective cohort study we have examined differences in survival profiles with respect to the body mass index in patients with mucosal melanoma on immune checkpoint inhibitor therapy. Materials and methods: The primary outcome included the association between the body mass index and overall survival in patients with metastatic mucosal melanoma. The secondary outcomes included the clinical presentation and management of vulvar and vaginal melanomas with oral and anorectal mucosal melanomas, as well as the surgical and radiological management of vulvar and vaginal melanomas. Kaplan–Meier analysis and log-rank test were used for the assessment of overall survival. Results: The results showed that patients with mucosal melanoma whose body mass index was ≥25 had better overall survival (p = 0.02). Overall survival was different between vulvar/vaginal vs. oral mucosal melanoma (p = 0.02). Overall survival was not different between vulvar/vaginal vs. anorectal melanoma (p = 0.77). Some immune toxicities were specific to patients with vulvar/vaginal melanoma. Conclusions: Obesity is associated with improved survival in patients with metastatic mucosal melanoma, although findings can be heterogeneous depending on the subtype of mucosal melanoma.

Published: February 2021

The purpose of the study was to learn more about readiness to pay for specialist health services and to learn about the acceptable level of co-payments through the opinions of anonymous respondents. A questionnaire was developed to conduct the survey and collect the data. The questionnaire was posted on an internet website and the respondents chose an appropriate answer variant. All questions were closed ones. The database was created in Excel. The analysis included 527 completed questionnaires. The analysis of the data collected identified the amount of acceptable co-payments for specialist medical consultations. According to the respondents, the co-payment amount should be equal for everyone, and privileged social groups should include only disabled and chronically ill people. The willingness to co-pay was declared most often by those with a higher monthly net income per person in a household and with a higher and secondary education. The study has shown that younger people accepted the subsidies more than the elderly. Due to the fact that younger people were the most represented in the data the least numerous declared level of education was basic education while the majority of respondents were urban residents, hence the results illustrated a number of essential and interesting observations. However, they cannot be applied as generalizations, although they inspire further expansion of the scope of the data collected and the conducting of further analyzes.

ABSTRACT Objectives: to understand the experiences of family members of drivers who violate the law against drinking and driving and the post-penal repercussions. Methods: a qualitative study, with family members of drivers who violated the law against drinking and driving who participated in the Projeto Justiça e Sobriedade no Trânsito de Maringá - PR (Traffic Justice and Sobriety Project in Maringá - PR). Data collection was carried through semi-structured interviews, analyzed through thematic analysis. Results: it was observed in the family members' reports: the suffering of families due to the consumption of alcohol and other drugs; the violation of the law against drinking and driving meaning turning point, with positive and negative changes in the family context; and the meanings of the Traffic Justice and Sobriety Project. Final Considerations: the law against drinking and driving penalties triggered unemployment and financial expenses, but the positive aspects were quitting alcohol use and/or not drinking and driving anymore. The Traffic Justice and Sobriety Project was informed as solidarity and a trigger for changing the offenders' behavior.
O Besouro na Caixa de Skinner,
Authors: Dourado Luiza Bacchi , Lopes Carlos Eduardo , Pompermaier Henrique Mesquita
Published: February 2021

Resumo A literatura tem indicado algumas aproximações entre as propostas de Skinner e Wittgenstein, como, por exemplo, a crítica às concepções tradicionais de linguagem psicológica. Wittgenstein assenta essa crítica na impossibilidade de uma linguagem privada, enquanto Skinner a faz por meio do conceito de eventos privados. Contudo, esse conceito parece não ser consistente com a proposta de Wittgenstein. Partindo dessa hipótese, este artigo pretende reavaliar o papel do conceito de eventos privados no comportamentalismo skinneriano à luz das discussões críticas de Wittgenstein. Para isso, é feita uma comparação entre as propostas de Wittgenstein e de Skinner, evidenciando que o conceito de eventos privados é suscetível às críticas de Wittgenstein às concepções tradicionais da linguagem psicológica.
Envolvimento Paterno em Pais de Crianças em Idade Escolar: Relação com Estresse Parental, Apoio Social e Variáveis Sociodemográficas
Authors: Arrais Ana L. , Vieira-Santos Salomé
Published: February 2021

Resumo Pretende-se averiguar se o estresse parental e o apoio social contribuem para o envolvimento paterno (EP), e analisar a relação desse envolvimento com variáveis sociodemográficas (pai/criança). Participaram do estudo 92 homens, pais de crianças em idade escolar (6 a 9 anos). Utilizou-se a Escala de Envolvimento Paterno e as adaptações portuguesas do Parenting Stress Index-Short Form e do Social Support Questionaire. Verificou-se que apenas o estresse parental (Interação e Criança) se constitui como preditor do EP (Cuidados e Disponibilidade). Verificou-se ainda uma associação entre o EP e o número de filhos. Os resultados sugerem que níveis elevados de estresse parental poderão ser prejudiciais para o envolvimento do pai em termos de cuidados e disponibilidade, sendo também relevante o maior número de filhos.

ABSTRACT: Myelolipoma is a benign neoplasm composed of mature adipocytes and hematopoietic elements. This tumor is rare in dogs and cats and can develop in several organs and tissues. This report describes a case of splenic myelolipoma in a dog characterizing its clinical-pathological and ultrasonography aspects. A 9-year-old, female, mixed-breed, castrated dog was referred to the veterinary hospital with increased abdominal circumference. Ultrasonography revealed splenomegaly with masses of not measurable dimensions along the entire length of the parenchyma. The spleen was removed, and a fragment was sent for histopathological analysis. Macroscopically, the spleen was enlarged, with irregularly nodular growths that project above the surface of the organ. Nodules were red with small yellow areas. Microscopically, the spleen was effaced by a well-demarcated and not encapsulated mass composed of histologically well-differentiated neoplastic adipose tissue with islands and nests of varying proportions of hematopoietic elements. Histological examination confirmed the diagnosis of myelolipoma. Myelolipomas are observed on ultrasound images as hyperechoic masses or nodules with homogeneous echo texture. Here, ultrasound appearance involved mixed echogenicity and heterogeneous echotexture, due to the mixture of fat and non-fatty material components of the tumor.

Published: February 2021

Resumo: Introdução: Erros de medicação são comuns e causam sofrimento e custos que podem ser evitados. A mitigação da ocorrência de eventos adversos a medicamentos é tratada como prioridade pela Organização Mundial da Saúde (OMS), que recomenda a inclusão do tema segurança do paciente nos currículos das profissões de saúde como medida para minimizar danos aos pacientes. Um curso on-line aberto e massivo (MOOC) sobre segurança no processo de medicação foi desenvolvido como estratégia educacional para a área da saúde e disponibilizado no Ambiente Virtual de Aprendizagem do Sistema Único de Saúde (Avasus), em março de 2018. Objetivo: Este estudo teve como objetivo avaliar a satisfação e o aprendizado dos participantes que concluíram o curso. Método: Trata-se de estudo de delineamento quase experimental não controlado. O MOOC possui uma carga horária de 30 horas e aborda temas sobre segurança na prescrição, dispensação, administração e notificação de incidentes relacionados a medicamentos. Aplicaram-se um pré-teste e um pós-teste de múltipla escolha para avaliar o nível de conhecimento dos participantes, e um questionário de satisfação foi respondido ao término do curso. Analisaram-se a confiabilidade dos instrumentos de medida, a significância da melhoria do conhecimento e os fatores associados (sexo, idade e profissão). Resultados: Dos 7.135 participantes inscritos no período de março a dezembro de 2018, 2.902 (40,7%) responderam aos instrumentos de pesquisa. A confiabilidade do questionário de satisfação foi boa (alfa de Cronbach = 0,83), e o curso foi bem avaliado como estratégia educacional (96,1%). Em relação ao nível de conhecimento, observou-se aumento significativo (antes = 8,10; depois = 8,74; p < 0,05) com melhoria relativa de 32%. O fator idade esteve diretamente associado à aprendizagem (β = 1,36; IC 95% = 0,35-2,36; p = 0,008). Conclusão: A utilização do MOOC mostrou-se efetiva para o ensino de segurança no processo de medicação, ferramenta que pode ser utilizada para a inserção do tema segurança do paciente nos currículos das profissões de saúde.

Published: February 2021

Resumo: Introdução: A medicina como área de conhecimento e prática tem invisibilizado a importância de gênero como categoria teórica na formação médica, bem como os impactos das diferenças e desigualdades de gênero expressas no contexto da prática clínica. Gênero é reconhecido como um aspecto crucial na educação médica, principalmente no sentido de promover a qualidade da assistência à saúde, considerando as diferenças de gênero nos sintomas, os fatores de risco da doença e o plano de assistência estabelecido no contexto da relação terapêutica. Objetivo: Com base nesse pressuposto, foi realizada pesquisa sobre a percepção da formação recebida sobre gênero no contexto da graduação e especialização médica de residentes em ginecologia e obstetrícia e medicina de família e comunidade de duas escolas públicas do município de São Paulo. Método: A pesquisa de abordagem qualitativa utilizou a técnica de entrevista em profundidade. Em 2016, 13 residentes de ambas as especialidades participaram da pesquisa, sendo sete de ginecologia e obstetrícia e seis de medicina de família e comunidade. O critério de inclusão era ser médico ou médica das residências em medicina de família e comunidade ou ginecologia e obstetrícia nas duas universidades públicas participantes do estudo. A fim de obter uma amostra não probabilística, utilizou-se a técnica de recrutamento em cadeia ou “bola de neve”, na qual os(as) participantes do estudo indicam outros(as) participantes até que se atinja o ponto de saturação. Resultados: Apesar de diferenças identificadas entre os(as) participantes, segundo os programas de residência, em relação à abordagem de gênero na formação médica e às suas repercussões na prática clínica, com maior apropriação pelos residentes de medicina de família e comunidade, sobressaem lacunas importantes na formação e no âmbito da graduação e especialização. Conclusão: O conhecimento e o desenvolvimento de habilidades e técnicas baseadas em abordagem de gênero na formação médica são fundamentais para o exercício do cuidado integral que considera as conformações socioculturais dos(as) pacientes e suas implicações para o processo saúde-doença.

Published: February 2021

ABSTRACT We aimed to improve the understanding of the establishment of Serrasalmus marginatus (non-native), which was followed by a decrease in the abundance of Serrasalmus maculatus (native) in the upper Paraná River floodplain. We estimated age, mortality rate, length and age at first maturity and variations in gonad development in three time-periods along a 26-year truncated time scale for both species. Population and reproduction parameters of both species showed substantial fluctuations among periods. Most age classes were sampled in all time-periods, but with considerable difference in abundance, with predominance of older individuals in the second time-period and younger individuals in the third time-period for both species. The mortality rates decreased for both species in the second time-period, but increased for the native in the third time-period. Length and age at first maturity decreased in the second time-period for both species, increasing the number of mature individuals on their populations. In the third time-period, the number of immature individuals increased for both species. We suggest that species experienced stressful conditions during cooccurrence and this have resulted in physiological responses in both species, reflecting in population and reproductive adjustments that may have relaxed competitive interactions between them, optimizing survival, reproductive effort and coexistence.

Resumo O objetivo deste artigo foi analisar o projeto educativo proposto como fundamento da Base Nacional Comum Curricular (BNCC). Realizamos uma pesquisa qualitativa e documental da versão final da BNCC, de abril de 2017, homologada em 20 de dezembro de 2017 pelo Conselho Nacional de Educação. Identificamos que a BNCC se fundamenta num projeto educativo de formação para a empregabilidade, com a centralidade das competências, a partir de um modelo de Ensino direcionado, prescritivo e vinculado a um modelo de avaliação eficientista, inspirado nas teorias comportamentais, e concluímos que as proposições da BNCC se distanciam de um projeto educativo que vise a uma formação crítica e emancipatória, ao formar para o trabalho segundo as demandas neoliberais.

Abstract: The objective of this work was to evaluate the agro-economic performance of sesame (Sesamum indicum) under nitrogen fertigation in the semiarid region of Northeastern Brazil. The experimental design was randomized complete blocks with four replicates, and the treatments were arranged in a split-plot, where the plots were assigned five N rates (0, 30, 60, 90, and 120 kg ha-1) and the sub-plots were represented by four sesame genotypes ('CNPA G2', 'CNPA G3', 'CNPA G4', and 'BRS Seda'). The following variables were evaluated in two agricultural harvests in 2016: gross and net incomes, rate of return, and profit margin. In both harvests, there was a variation in production costs between N rates. In the second harvest, the highest values of net income were achieved with 120 kg ha-1 N fertigation, being: R$7,428.36 ha-1 for 'CNPA G2', R$8,630.74 ha-1 for 'CNPA G3', R$9,828.64 ha-1 for 'CNPA G4', and R$8,354.06 ha-1 for 'BRS Seda'. Increasing N rates provide an increase in the gross income, net income, rate of return, and profit margin for sesame producers. Fertigation with 120 kg ha-1 N provides the maximum agro-economic performance for sesame, whereas the 'CNPA G4' genotype shows the greatest agro-economic efficiency.
Influence of creep on the small-strain stiffness of sand–rubber mixtures
Authors: Tian Yu , Senetakis Kostas
Published: February 2021

A series of bender element tests was carried out to investigate the variation of small-strain stiffness (Gmax) of sand–granulated rubber mixtures under long-term loading. Comparisons were made using two different host sands: a non-crushable material called Sydney sand and a crushable material composed of completely decomposed volcanic rock (CDV). The test results suggested that, at the selected stress states in the study (mean effective confining stress ranged from 250 to 333 kPa), the influence of creep on the stiffness of the pure sand specimens was more pronounced for CDV compared with Sydney sand and the presence of rubber amplified creep effects on both types of mixtures. The influence of creep on Gmax was therefore associated with two major mechanisms: the increased compressibility of specimens predominantly because of grain crushing (contribution of sand fraction), and the increased compressibility because of the presence of soft rubber grains (contribution of the rubber fraction). The significant influence of grain breakage on the relationship between stiffness and creep was confirmed by post-test examination of the grain-size distribution curves of pure CDV samples. For rubber–CDV mixtures, the inclusion of soft and viscoelastic rubber grains prevented breakage, in this way reducing the creep mechanism due to grain crushing, but increased the overall influence of creep on stiffness. These conclusions were drawn based on 20% of rubber by mixture weight, and very similar behaviour was observed for 10% rubber. It was therefore understood that the aggravation of creep induced by the increased deformations due to the presence of rubber, for the given contents of rubber included in the study, was more dominant compared with the adverse influence of rubber on samples’ creep by preventing sand grain breakage.

Klára Verseghy used the term “Fragm. typi” in her catalogue of the type specimens deposited in BP. However, this status is in conflict with the Code. “Fragm. typi” were replaced by lectotype and isolectotype of the following names: Buellia samothrakiana, Caloplaca servitiana, Catillaria servitii, Catillaria zsakii, Lecania nylanderiana var. ochracea, Lecanora atra var. aegaeica, L. cengiae-samboae, L. rhodi, Lecidea aegaeica f. acrustacea and Rinodina samothrakiana.
Middle Miocene (Badenian) chondrichthyan and osteichthyan remains from St. Margarethen (eastern Austria) in the vertebrate palaeontological collection of the Hungarian Natural History Museum
Authors: Szabó Márton
Published: February 2021

To actualize the available data regarding Cenozoic fi sh materials housed in the vertebrate fossil collection of the Hungarian Natural History Museum (HNHM), Middle Miocene (Badenian) chondrichthyan remains, unearthed at St. Margarethen (Burgenland, eastern Austria) are revised in detail. Among the specimens, a mislabelled, slightly disarticulated, partial dentition surrounded by associable placoid scales and portions of suggested cartilage, referred to a juvenile individual of an indeterminate Carchariidae or Odontaspididae has been found. This specimen represents the first articulated shark fossil ever discovered in the Miocene of the Central Paratethys. The material also includes a large-sized, pathological tooth of Otodus (Megaselachus) megalodon, which is the largest and most spectacular of all Otodus (Megaselachus) megalodon teeth of the HNHM collection. The HNHM collection includes osteichthyan remains, also unearthed at St. Margarethen, but these specimens are only shortly mentioned. Although the Middle Miocene marine vertebrate fossils of St. Margarethen are actively investigated for over one and a half centuries, the HNHM material adds new and important data to our knowledge on the locality’s chondrichthyan fauna. The present paper also highlights the importance of accurate re-investigation of museum fossil collections. With 112 figures.
South Africa's Weekly Media: Front-Page Reporting 9/11, Preventing Islamophobia
Authors: Abbasi Iskander
Published: February 2021

New York's twin tower bombings, popularly referred to as 9/11, are regarded as a watershed period in world affairs. It happened at the cusp of the new century and its impact, since then, has been enormous, for it radically changed many aspects of human life. Both the print and the electronic media were pivotal in these changes. Besides shaping the way that communities perceive others, it also influenced the manner in which communities are dealing with one another. Since a radical Muslim group was blamed for this dastardly deed and since Muslims were implicated for this reprehensible act, the secular media expectedly placed the Muslims - in majority and minority settings - around the world under the spotlight. The media's negative portrayal and reporting about Muslims did not only contribute towards a tendentious relationship between the media and the Muslims but it also contributed towards the spread of Islamophobia. This thus caused Muslims in both majority and minority settings to adopt a skeptical view of the role of the secular media. Considering these developments, this essay's focus turns to the South African print media that reported and analyzed their reporting of this event during that period. Since it is beyond this essay's scope to look at all the country' s daily and weekly tabloids, it restricted itself to two widely circulated South African weekly newspapers, namely the Sunday Times and Mail & Guardian. It first describes and discusses their front-page reports as they captured the tragic 9/11 event, before it reflects on their editorials -columns providing one with insights into the respective editors' understanding of this event and their perceptions of Muslims nationally and globally. Being a purely textual study, it conceptualizes Islamophobia as the essay's conceptual frame.

Objective:
Although the efficacy of the visual interpretation of 99mTc-MIBI myocardial perfusion imaging has been repeatedly confirmed in the diagnostic and prognostic evaluation of coronary artery disease (CAD), the efficacy of the automated quantitative evaluation dependent on computer programs is controversial. In our study, we compared automated quantitative data, such as the sum stress score (SSS) and the sum difference score (SDS), with coronary angiography results. We investigated the ability of SSS and SDS values to predict coronary artery disease.
Method:
SSS and SDS are measurements used in the global scoring of myocardial perfusion. While SSS indicates the degree of ischemia, SDS defines the reversibility degree of ischemia. In the global scoring of myocardial perfusion, when the SSS was 4 and above, MPI was evaluated as positive. In the coronary angiography, a stenosis value of >50% was evaluated as positive. We divided the SSS into three groups; mild (4-8), moderate (9-12), and advanced (>13) hypoperfusion. We divided the SDS into two groups as below and above 10%. We compared the subsequent quantitative data with the results of the three groups of coronary angiographies (70% stenosis).
Results:
A total of 104 patients who underwent angiography were included in the study. The accuracy in detecting positivity between the general quantitative MPI and angiography methods of the patients was calculated as 80.8%. The agreement value was found to be significant (Kappa=0.602; p
