A pair of commuting hypergeometric operators on the complex plane and bispectrality
Authors: Molchanov Vladimir F. , Neretin Yury A.
Published: March 2021

We consider the standard hypergeometric differential operator

\mathcal D

regarded as an operator on the complex plane

\mathbb C

and the complex conjugate operator

\bar{\mathcal D}

. These operators formally commute and are formally adjoint one to another with respect to an appropriate weight. We find conditions when they commute in the Nelson sense and write explicitly their joint spectral decomposition. It is determined by a two-dimensional counterpart of the Jacobi transform (synonyms: generalized Mehler–Fock transform, Olevskii transform). We also show that the inverse transform is an operator of spectral decomposition for a pair of commuting difference operators defined in terms of shifts in imaginary direction.
A quantitative stability theorem for convolution on the Heisenberg group
Authors: O'Neill Kevin
Published: March 2021

Although the convolution operators on Euclidean space and the Heisenberg group satisfy the same

L^p

bounds with the same optimal constants, the former has maximizers while the latter does not. However, as work of Christ has shown, it is still possible to characterize near-maximizers. Specifically, any near-maximizing triple of the trilinear form for convolution on the Heisenberg group must be close to a particular type of triple of ordered Gaussians after adjusting by symmetry. In this paper, we use the expansion method to prove a quantitative version of this characterization.

Published: March 2021

The soil seed bank is the primary source of regeneration in wetlands and has different assessment methods that vary according to the objective of the study. We evaluated the seed bank composition using three methods: seedlings emergence (EME), seedlings emergence with submersion trays in water (SUB) and screening and counting seeds (COU), and finally, we evaluated the applicability of COU to assess seed predation. The abundance and species richness were evaluated for two years at the end of the flood and dry seasons, in the Brazilian Pantanal. The abundance and species richness differed significantly between methods and seasons. The COU method showed the highest richness (84) and abundance (95.023) followed by EME and SUB. The SUB method reflected only the aquatic community. In the flood season, EME and COU methods showed similar species composition. There were no differences between COU and EME + SUB. The main advantage of COU method was the possibility to assess the seed predation, and we detected that Croton trinitatis had 32% of predated seeds. We consider that wetland ecosystems can be sampled by both methods COU and EME + SUB; however, the complete method that can be used for different purposes is COU, also, must be considered the infrastructure and objective of each study.

Among the rocky shores’ biota, the networks of interaction between macroalgae and associated organisms, especially gastropods, stand out. In order to contribute to the understanding of the ecology of rocky shores, this study aims to evaluate the relation between macroalgae and associated gastropods in Ribanceira Beach, Imbituba, Santa Catarina, Brazil. The survey of algae samples took place in a wet season, using 20 cm x 20 cm quadrants, allocated in 18 transects distributed equally in the infra and mesolittoral zones, with five points each. In the laboratory, algae were screened and associated gastropods identified. Concepts of network theory were applied for a better understanding of interactions among organisms, where connectance descriptors, niche overlap and centrality index for each species were calculated. Multivariate techniques were used to assess the significance of intertidal zones, morphofunctional group and other variables in the composition of the associated gastropods. The sampling resulted in a total of 1.466 gastropods, distributed in 14 species and nine families. In relation to the macroalgae, 14 species were identified, with seven presenting associated gastropods. The ecological network showed low connectance and niche overlap for both levels (gastropods and macroalgae), suggesting the existence of many specific interactions. The centrality values highlighted Eulithidium affine (C.B. Adams, 1850) and Sargassum cymosum C. Agardh as key species in the studied network. The mass and morphofunctional group of the macroalgae sampled showed influence in the composition of the associated community. Cortical algae, especially S. cymosum, stood out with high levels of species richness and species density of associated gastropods, suggesting importance in the structural complexity of macroalgae for gastropods. The non-significant effect of the tidal zone for the gastropod composition was highlighted, suggesting that the nesting and foraging stability provided by the macroalgae allows the same gastropod species to occur in both infralittoral and mesolittoral zones.
ENVIRONMENTAL STRESS AND FLUCTUATING ASYMMETRY IN ANTILOPHIA GALEATA, MYIOTHLYPIS FLAVEOLA AND BASILEUTERUS CULICIVORUS IN BRAZILIAN SAVANNA
Authors:   Universidade Federal de Uberlândia, Gonçalves Vanessa Fonseca , Melo Celine de
Published: March 2021

Fluctuating asymmetry (FA), defined as the random difference between two sides of a bilaterally symmetrical character, is often used to monitor biological populations in altered habitats. We aimed to compare the values of FA for wing and tarsi of three bird species (Antilophia galeata, Myiothlypis flaveola and Basileuterus culicivorus) in areas with different environmental stresses and to analyze their potential use as biomonitors. The birds were captured between March 2010 and March 2011, in seven forest fragments. In areas of high environmental stress, FA was higher for the wings of A. galeata and M. flaveola and the tarsi of B. culicivorus. FA depends on the functional importance of the character for each species. Thus, this study demonstrated that FA in wings and tarsi is a useful tool to assess the quality of the Brazilian Savanna (Cerrado) forest habitat.

The aim of this study was to assess the abundance and richness of microcrustacean, and water physical and chemical characteristics of a high-altitude pond in the Serra do Mar at State of Paraná. Water samples were collected quarterly between August 2015 and August 2016. Environmental conditions of pond were characterized by small pond size and depth, cold and well oxygenated water, and neutral or slightly acid pH. Mean total microcrustacean density was 945.0 ind m-3, whereas total taxon richness was 3.40. The most abundant species was Tropocyclops prasinus. The small size and the isolament of the pond, and the low temperatures were related to the low species richness and abundance. This study is unprecedented to the State of Paraná. Future studies attempt to understand the environmental conditions and distribution of microcrustaceans from high-altitude ponds.

It is about half a century since free-living amoebae were recognized as pathogenic organisms, but there is still much we should learn about these rare fatal human infectious agents. A recently introduced causative agent of granulomatous amoebic encephalitis, Balamuthia mandrillaris, has been reported in a limited number of countries around the world. A 3-year-old girl was referred to our tertiary hospital because of inability to establish a proper diagnosis. She had been experiencing neurologic complaints including ataxia, altered level of consciousness, dizziness, seizure, and left-sided hemiparesis. The patient's history, physical examination results, and laboratory investigations had led to a wide differential diagnosis. Computed tomography (CT) scan and magnetic resonance imaging analyses revealed multiple mass lesions. As a result, the patient underwent an intraoperative frozen section biopsy of the brain lesion. The frozen section study showed numerous cells with amoeba-like appearances in the background of mixed inflammatory cells. Medications for free-living amoebic meningoencephalitis were administered. PCR assay demonstrated B. mandrillaris as the pathogenic amoeba. Unfortunately, the patient died 14 days after her admission. To our knowledge, this is the first report of B. mandrillaris meningoencephalitis in the Middle East and the first time we have captured the organism during a frozen-section study.

O objetivo desta pesquisa foi investigar a influência do exercício resistido máximo e submáximo com diferentes períodos de intervalo de recuperação entre séries sobre as concentrações de testosterona total e cortisol em jovens treinados. Seis jovens treinados (22±3,3 anos) realizaram 4 sessões de treinamento resistido com diferentes intensidades e períodos de intervalo de recuperação entre séries (PI). As sessões apresentavam as seguintes características: (sub60): 3x10 rep., 70% de 10RM, PI 60seg.; (max60): 3x8-12 rep., 95% de 10RM, PI 60seg.; (sub180): 3x10 rep., 70% de 10RM, PI 180seg.; (max180): 3x8-12 rep., 95% de 10RM, PI 180seg. Os exercícios utilizados foram: supino reto, pressão de pernas, puxada pela frente na polia alta e cadeira extensora. Dez minutos antes e imediatamente após as sessões de treinamento, amostras de sangue foram coletadas para determinação das concentrações de testosterona total e cortisol. Foi constatado aumento na concentração de testosterona total na sub60 (17±10%; p=0,013), sub180 (20±12%; p=0,005) e max60 (20±14%; p=0,014). Para o cortisol, foi observado redução apenas na sub180 (-38±10%; p=0,001). Aumentos na relação testosterona/cortisol foram encontrados na sub60 (p=0,044) e sub180 (p=0,003). Os valores da testosterona total foram mais elevados na sub60 em relação a sub180 (p=0,039) e max180 (p=0,048) no momento POS. A sessão de treinamento resistido envolvendo exercícios submáximos e período de intervalo de recuperação entre séries longo (sub180) foi efetiva em elevar a testosterona total e reduzir o cortisol em jovens treinados, resultando em uma alta relação testosterona/cortisol e favorecendo um melhor ambiente anabólico.

Lymphomas are a heterogeneous group of hematological neoplasms that can occur in individuals of both sexes and of all ages. They are subdivided into Hodgkin's and non-Hodgkin's lymphoma, and originate from lymphocytes at different stages of development and can affect any organ. Its diagnosis is not always easy since it presents with varied symptoms, and for this reason, it is often diagnosed at an advanced stage. National data on the epidemiology of lymphomas are limited. The objective of this study is to analyze clinical and epidemiological data of individuals with lymphoma in a cancer treatment reference center in Paraná. Observational, retrospective study of analysis of medical records of patients over 18 years of age, of both genders, diagnosed with Hodgkin's and non-Hodgkin's lymphoma followed by the Londrina Cancer Hospital in the year of 2018. The data collected were number of cases, age, sex, municipality of origin and Ann Arbor clinical staging. Our study found a low incidence of non-Hodgkin's lymphoma and a high frequency of advanced disease compared to other centers. Patients with advanced disease came from cities with a lower median Human Development Index (HDI) compared to those with early disease. The analysis of patients with Hodgkin's lymphoma found data similar to that of other centers. The low incidence of non- Hodgkin's lymphoma and the high number of cases with advanced disease allows the development of strategies for recognizing the disease and improve assistance to the population in Londrina region.

No Brasil, o câncer é a principal causa de morte por doença em crianças e adolescentes. O Instituto Nacional do Câncer (INCA) estima a ocorrência de 8.460 novos casos de câncer em crianças e adolescentes no ano de 2020.O objetivo desse estudo foi identificar as manifestações bucais mais frequentes nos pacientes pediátricos em tratamento antineoplásico. Essa pesquisa incluiu 137 crianças e adolescentes de 0 a 19 anos de idade. Os dados incluíram um questionário semiestruturado para verificar as manifestações bucais mais frequentes decorrentes da terapia antineoplásica. Os testes estatísticos utilizados foram o teste Qui-quadrado de Pearson e para avaliar a força da associação foi obtido o Odds Ratio (OR) ou Razão das Chances (RC) com respectivo intervalo de confiança. Os resultados encontrados demonstram que a idade média dos pacientes pesquisados foi de 6,8 anos; o sexo masculino (57,7%) foi predominante na amostra; a neoplasia maligna mais incidente foi à leucemia (67,9%); 70,1% dos pacientes apresentaram pelo menos uma manifestação oral, sendo a mucositede maior prevalência (56,2%), seguida da xerostomia (46,7%), gengivite (41,6%), disfagia (35,8%), disgeusia (35,8%), candidíase (34,3%) e herpes (21,2%). Encontraram-se 54,7% dos pacientes com saúde bucal favorável e 40,9% deles com saúde bucal desfavorável. Concluímos que o paciente infantil deve ser avaliado por um odontopediatra previamente ao início da quimioterapia para minimizar as complicações bucais durante o tratamento antineoplásico.

As transformações fisiológicas decorrentes da gestação e hábitos durante a gravidez motivam o interesse sobre a necessidade de um pré-natal odontológico, para que se entenda as repercussões na saúde bucal da mãe e do recém-nascido. A gestação é uma fase adequada para promoção de saúde bucal, pois é um momento que a mulher é mais receptiva a aquisição de novas práticas que ajudam no autocuidado e favorecem o desenvolvimento de seu bebê. Este estudo teve como objetivo revisar a literatura acerca da importância do pré-natal odontológico e da repercussão das alterações fisiológicas na gestação e hábitos da mãe sobre o infante. Tratou-se de uma revisão de literatura, tendo por critério de elegibilidade a seleção de artigos nos idiomas inglês, português e espanhol, indexadosàs bases de dados PubMed e SciELO, de 2009 a 2019, através do operador booleano “AND”.A inclusão da Odontologia no acompanhamento das gestantes é vista como parte essencial dos cuidados no pré-natal, considerando que alterações físicas e comportamentais durante este período estão associadas às reações inflamatórias no tecido gengival, propiciando a instalação de manifestações bucais como a cárie dentária e a doença periodontal. Sãoressaltados os empecilhos encontrados quanto à falta de informação da gestante, despreparo profissional por falta de conhecimento para o atendimento e a dificuldade de acesso ao serviço. A inclusão da Odontologia no pré-natal é importante, visto que evita desordens na saúde geral e bucal materno-infantil

A anomalia dentária de desenvolvimento mais comum na dentição humana é a agenesia dentária, que pode acontecer nas dentições decídua e permanente. Os dentes mais acometidos pela agenesia são os terceiros molares, pré-molares e incisivos laterais superiores. Comumenteestá associada a outros tipos de anomalias como a microdontia, ectopias e atraso no desenvolvimento dentário. Portanto, o cirurgião dentista deve se atentar para o desenvolvimento de outras anomalias para que o diagnóstico e a interceptação ortodôntica aconteçam em momento oportuno. Foi realizada uma avaliação das radiografias panorâmicas da documentação de 50 pacientes, selecionados aleatoriamente, com idade entre 6 e 20 anos, de ambos os gêneros, excluindo pacientes sindrômicos, que buscaram tratamento ortodôntico no Curso de Pós-graduação em Ortodontia do Centro Universitário de Volta Redonda. O objetivo desse estudo observacional foi avaliar a presença de agenesia de algum elemento dentário permanente, excluindo os terceiros molares, identificar os dentes mais acometidos, bem como, a associação com outras anomalias dentárias.Avaliando os resultados observou-se que 9 pacientes apresentavam agenesia dentária (18%), com maior prevalência no gênero feminino (55,6%). Os dentes mais acometidos foram os incisivos laterais superiores, seguido dos segundos pré-molares inferiores e segundos pré-molares superiores. A presença de outras anomalias dentárias associadas à agenesia foi identificada em 4 pacientes (44,4%), com predomínio no gênero feminino (75%), que foram o atraso no desenvolvimento dentário, forma conóide, ectopia no posicionamento e dilaceração radicular. Concluiu-se que na amostra estudada houve alta prevalência de agenesia dentária, tendo como referência outros estudos com pacientes ortodônticos.

Embora o Brasil seja um país de tradição no futebol, pouco se tem investigado acerca dos aspectos relacionados à saúde de jogadores, sobretudo no que tange o futebol feminino. Com isso, o objetivo do estudo foi descrever o perfil dos fatores de risco para o desenvolvimento de doenças crônicas não transmissíveis (DCNT), de comportamento sedentário e sócio demográfico de jogadoras amadoras de futebol para mulheres. Participaram do estudo 41 jogadoras residentes em Ilhéus e Itabuna (BA), com 26, 8 ± 7, 3 anos de idade. Foi aplicado um questionário para avaliar informações sócio-demográficas (idade, sexo, nível de escolaridade, renda familiar), fatores de risco para o desenvolvimento das DCNT (nível de atividade física, tabagismo, consumo de álcool, consumo alimentar, sobrepeso/obesidade) e comportamento sedentário. Observou-se que 46,3% das jogadoras se autodeclararam pardas, 73,2% com Ensino Médio completo e que apresentaram renda familiar média inferior a dois salários mínimos. Sobre os fatores de risco, as jogadoras foram classificadas como ativas fisicamente (100%), sem hábito de fumar (92,7%), consumidoras de frutas e legumes (95,1%) e que apresentaram padrões antropométricos normais (63,4%). Entretanto, reportaram o consumo abusivo de álcool (51,2%) e dispêndio de grande parte do tempo livre em comportamento sedentário (75,6%). Conclui-se que as jogadoras apresentam em sua maioria bons indicadores de saúde, entretanto o consumo abusivo de álcool e o comportamento sedentário são indicadores preocupantes.

La educación física curricular es hoy un derecho de todo el alumnado de la escuela primaria en Uruguay, y tiene carácter de obligatoriedad desde el 2008. Este trabajo informa sobre la investigación que se originó en base a la preocupación de conocer cómo se enseña el deporte escolar en el ámbito de la educación física curricular de escuelas públicas y privadas de Montevideo, y si sus niños y niñas tienen oportunidad de acceder a competiciones, y en ese caso, a qué tipo de competiciones. El objetivo fue comprender las relaciones existentes entre el deporte escolar y sus propuestas de competición, estudiando los supuestos teóricos que lo sostienen. El diseño metodológico fue mixto: de nivel exploratorio-descriptivo para identificar cuáles son las competiciones existentes y describir sus características, y de nivel explicativo-interpretativo, a fin de estudiar las concepciones teóricas que fundamentan las estructuras de competiciones y establecer semejanzas y diferencias. Los hallazgos confirman que abordar el estudio de la competición deportiva escolar es un fenómeno complejo, que existen puntos de encuentro entre los ámbitos público y privado, pero también algunas tensiones. El objetivo de este artículo es además de divulgar la información, jerarquizar la profesión poniendo en discusión la temática que permita pensar mancomunadamente en la transformación de la enseñanza del deporte escolar hacia una educación deportiva más equitativa que promueva la igualdad de oportunidades al alumnado, independientemente si asisten a una escuela pública o privada de Montevideo.

Authors: Merianos Ashley , Vidourek Rebecca , King Keith
Published: March 2021

Over the past decade, cosmetic procedures have significantly increased in options available for females to achieve the American cultural standards of beauty. The purpose of this study is to conduct a content analysis of brochures and to observe what cosmetic procedures are made available to female customers from plastic surgery centers, and also to examine the medical and therapeutic framing techniques used to encourage females to undergo cosmetic procedures. Three plastic surgery centers (overall response rate= 60%) located in one metropolitan area served as participants for this study. The researcher observed the locations and collected all brochures made available. Twenty - one diverse brochures were used in this study as well as the researcher locate d the websites to view any missing information of services offered not included in the brochures. A content analysis was conducted of the brochures. All of the cosmetic surgery centers were accredited and advertised each plastic surgeon’s credibility. Various invasive and noninvasive cosmetic procedures were offered by each center including procedures that focus on the face, breasts, body, and skin care. Additionally, all cosmetic surgery centers marketed their elective surgeries to females by using medical terms as well as therapeutic terms. As the rates of cosmetic procedures have significantly increased overtime, cosmetic surgeons appear to benefit from employing medical terms to diagnose beauty among their target population of healthy females. In addition, using therapeutic terms to ensure increase self - esteem among females is another beneficial framing technique.

Authors: Chandler Rasheeta , Antsey Erica , Munro Cindy , Morrison-Beedy Dianne
Published: March 2021

Qualitative research emphasizes and honors the words of participants in an effort to generate meaning and knowledge, yet participants’ voices are rarely heard beyond data collection and analysis. We explore the potential to share participants' voices when disseminating research through audio - enhanced poster presentations. Technological advancements in multimedia could revolutionize poster presentations, especially for qualitative research. We describe the history of audio guides and how they can be applied to the dissemination of qualitative research. We also introduce the Experiencing Audio Recorded Research (EARR) Model to facilitate designing a multisensory approach to qualitative data dissemination through integrating audio technology into presentations.
Real Projects, Virtual Worlds: Coworkers, their Avatars, and the Trust Conundrum
Authors: Lohle Michael , Terrell Steven
Published: March 2021

This qualitative study informs project managers of the impact that the authentic projection of coworker identity via avatars has on trust and potential project management success when teams use virtual worlds to collaborate. By exploring the common experiences and reactions of potential virtual team participants to a demonstration that showed how to customize avatars and use them to communicate with others, it facilitated the development of a grounded theory that confirms whether the projection of authenticity via avatars is an antecedent of team trust and real project management success. Real management success was the main objective, since it is vital for the enterprise to use all means possible for competitive advantage in an ever-expanding technological society.
From Computer to Commuter: Considerations for the Use of Social Networking Sites for Participant Recruitment
Authors: Hirsch Lily , Thompson Kirrilly , Every Danielle
Published: March 2021

The rise in use and changing nature of the Internet has led to an increase in the number of people using discussion forums and social networking sites for the purpose of online social interaction, sharing experiences, and learning. Whilst researchers have begun to capitalize on the increasing pool of online participants for research online, very few studies have examined the benefits of online participant recruitment for offline data collection. Through the format of a ‘back stage’ essay, this paper follows the research process of participant recruitment using a social networking site to arrange offline interviews with local rail users in Mumbai and Chennai, India. This paper contributes to the literature about the methodological issues associated with ensuring authenticity of online-recruited research participants. It also builds on the existing literature about incorporating researcher safety into the method.
INFLUENCE OF ACCULTURATION ON THE BRAND SELECTION OF THE SOUTH ASIAN DIASPORA IN THE UK
Authors:   Bahauddin Zakariya University, Multan., Rizwan Muhammad
Published: March 2021

It is found throughout the literature that culture is an important influence on consumer behaviour. Those people who migrate to another country belong to a different class of consumers, who is influenced by home or host culture simultaneously. This study is aimed to explore the influence of acculturation on the brand choice of the South Asian immigrants in the UK. This study used a quantitative methodology to test a proposed model, developed with the help of past studies. A survey instrument was developed to collect data from the South Asian immigrant population living in the UK. Structural equation modelling was used to test the hypotheses. The study found that various personal factors like length of stay in the UK and income positively influence the acculturation, while acculturation decreasing with the increasing age among the South Asians in the UK.This study provides an insight about looking beyond the demographic variables while developing strategies to attract the market segments. The brand marketing management in the UK and other western countries while attracting the diaspora should understand the level of acculturation of their target market. The retailers may also consider the consumer cultural profile while deciding their product mix.

Published: March 2021

The sandworm (Sipunculus nudus) is an aquatic species of economic importance because of its high nutritional and medicinal value. Under the same culture conditions, substantial individual growth variation is often found in populations of sandworms. However, the genetic mechanisms of individual growth variation are poorly understood. In this study, the transcriptome of the body wall muscle of the sandworm at different growth rates was analyzed by Illumina sequencing and bioinformatics analysis. A total of 185 181 unigenes were obtained after processing raw reads and about 96,824 (47.72%) of them were annotated. Among the annotated transcripts, 418 differentially expressed genes were identified, of which 207 were upregulated and 211 were downregulated in large worms relative to small worms. We identified several genes that had a possible association with individual growth variation. These results will provide insight into the growth mechanism of sandworm, and will further assist in the selective breeding of improved strains of this species.

In the present study, highest SGR (Specific Growth Rate) was obtained in 20% in Lemna minor and 10% in Echhornia crassipes. The leaves of aquatic plants had considerable amount of crude protein and crude lipid, which improves the growth of fingerlings of fish upto a certain levels of inclusions, thereby reducing the feed cost. The slow growth performance might be due to absence of natural feed in the laboratory culture. The leaf meals inclusion has much advantage in growth performance of fish. However these leaf meals need processing to lower their fibre content, which to be used as fish feed.

Published: March 2021

A chegada do século XX trouxe significativos avanços de infraestrutura urbana, que repercutiram nas maneiras de habitar a cidade e consequentemente as residências. As exigências salutares do novo século impulsionaram a conformação de uma nova tipologia arquitetônica, as villas e casas de catálogo. Essas residências, caracterizadas pela sua premente ventilação e iluminação naturais buscam, por sua natureza, a característica de grandes lotes para suas implantações. Este artigo analisa como esse novo tipo edilício se implantou na região mais antiga da cidade de Pelotas-RS, o sítio do Primeiro Loteamento, que possui a característica de lotes estreitos e compridos. A investigação proposta pretende compreender como essa arquitetura se inseriu na malha urbana mais antiga da cidade, estabelecendo relações entre a tipologia arquitetônica e a morfologia urbana. A análise dos resultados foi realizada a partir dos dados coletados através de um inventário de varredura, que permitiu entender as principais características do sítio e das edificações estudadas.
Does Foreign Aid Contribute to HDI Improvement?
Authors: Signor Jordan , Vandernoot Julien
Published: March 2021

Foreign aid is aimed at creating a favourable environment capable to foster
economic growth and development in poorer countries. Accordingly, recipient
countries might rely to a certain extent on external aid to attaint higher welfare
levels. In principle, donour’s aid-allocation preference, aided country policies, its
institutional background, and economic environment are decisive in the aid
effectiveness. Should not the previous conditions be met, could the country fall into
the poverty trap. Contrary to a large strand of the literature measuring the role
external funding has with regards to its contribution to welfare and growth, we show
that Human Development Index is positively driven by internal factors, whilst
foreign aid, and private funding have no significant effect. This is coherent with a
more recent strand of the literature, suggesting that on average, aid is ineffective in
recipient countries.
