ABSTRACT

To enhance the field of continuous motor health monitoring, we present FAN-COIL-I, an extensive vibration sensor dataset derived from a Fan Coil motor. This dataset is uniquely positioned to facilitate the detection and prediction of motor health issues, enabling a more efficient maintenance scheduling process that can potentially obviate the need for regular checks. Unlike existing datasets, often created under controlled conditions or through simulations, FAN-COIL-I is compiled from real-world operational data, providing an invaluable resource for authentic motor diagnosis and predictive maintenance research. Gathered using a high-resolution 32 KHz sampling rate, the dataset encompasses comprehensive vibration readings from both the forward and rear sides of the Fan Coil motor over a continuous two-week period, offering a rare glimpse into the dynamic operational patterns of these systems in a corporate setting. FAN-COIL-I stands out not only for its real-world applicability but also for its potential to serve as a reliable benchmark for researchers and practitioners seeking to validate their models against genuine engine conditions.

ABSTRACT

The Wi-SUN FAN (Wireless Smart Ubiquitous Network Field Area Network) standard is attracting great interest in various applications such as smart meters, smart cities and Internet of Things (IoT) devices due to the attractive features that the standard offers, such as multihop and mesh topologies, a relatively high data rate, frequency hopping, and interoperability between manufacturers. However, the process of connecting nodes in Wi-SUN FAN networks, which includes discovering, joining, and forming the network, has been shown to be slow, especially in multihop environments, which has motivated research and experimentation to analyze this process. In the existing literature, to measure network formation time, some authors have performed experiments with up to 100 devices, which is a costly and time-consuming methodology. Others have used simulation tools that are difficult to replicate, because little information is available about the methodology used or because they are proprietary. Despite these efforts, there is still a lack of information to adequately assess the formation time of Wi-SUN FAN networks, since the experimental tests reported in the literature are expensive and time-consuming. Therefore, alternatives such as computer simulation have been explored to speed up performance analysis in different scenarios. With this perspective, this paper is focused on the implementation of the Wi-SUN FAN network formation process using the Contiki-NG open source operating system and the Cooja simultor, where a functionality was added that makes it possible to efficiently analyze the network performance, thereby facilitating the implementation of new techniques to reduce network training time. The simulation tool was integrated into Contiki-NG and has been used to estimate the network formation times in various indoor environments. The correspondence between the experimental and numerical results obtained shows that our proposal is efficient to study the formation process of this type of networks.

ABSTRACT

An increase in the frequency of severe hydrological events has highlighted the importance of sustainable water management in intensive agricultural regions. In a warming climate, improved understanding and stewardship of water resources are needed to guarantee water supply, ensure food security, and build resilience against extreme events. In this study, we evaluate a framework that combines spectral analysis and geochemical tracers as a potential tool for (1) gaining valuable insights into surface water (SW)-groundwater (GW) interactions, and (2) providing guidance for improved water management in an intensive agricultural basin in southern Guatemala. The framework proves to be useful in revealing important water dynamics, exposing key feedback mechanisms for water availability and quality. With the use of power density functions and hydrochemistry (T, pH, EC, and major ions), two specific interaction regimes (influent and effluent) were identified and delimited for the main watercourse. These segments are estimated to interact at high rates with the shallow aquifer in the river channel proximities and would lose influence towards the basin flanks. Furthermore, the δ2H and δ18O values indicate that regional groundwater flow systems play an essential role in the basin groundwater recharge. Lastly, we established three influence zones that depict the spatial extent of the SW-GW interactions within the basin. With these zones, we provide recommendations that will allow for further investigation and application into better water management strategies regulating groundwater development and land use activities within the agricultural context of the area.

ABSTRACT

Desde a década de 1980, os repasses por direitos de transmissão dos jogos de futebol representam parcela importante das finanças dos clubes brasileiros. Nas negociações para o período de 2019-2024, o ingresso do canal Esporte Interativo, da estadunidense Turner, alterou o modelo e os valores dos acordos. Porém, com a crise sanitária global provocada pelo surto de um novo coronavírus, em 2020, os mais variados negócios foram impactados pelas restrições de circulação de público, incluindo as atividades ligadas ao futebol. Deste modo, este artigo teve como objetivo identificar algumas das transformações nas relações do futebol nacional com os meios de comunicação, incluindo o debate acerca da nova "Lei do Mandante", aprovada em 2021. Com base em revisão de literatura narrativa e coleta de dados em sites diversos, os resultados apontam para o crescimento do uso de novas plataformas de mídia associado a mudanças da legislação esportiva brasileira.


Since the 1980s, transfers for broadcasting rights for football matches represent an important part of the finances of Brazilian clubs. In the derivations for the period 2019-2024, the entry of the Esporte Interativo channel, by the American Turner, changed the model and values of the agreements. However, with a global health crisis caused by the outbreak of a new coronavirus in 2020, the most varied businesses were impacted by restrictions on public circulation, including activities related to football. Thus, this article aimed to identify some of the transformations in the relationship between national football and the media, including the debate on the new "Mandante Law", approved in 2021. Based on a narrative literature review and data collection on different websites, the results point to the growth in the use of new media platforms associated with changes in Brazilian sports legislation.

ABSTRACT

Resumen En el presente trabajo, se registra por primera vez floraciones algales nocivas del dinoflagelado Blixaea quinquecornis (Abé) Gottschling, 2017 para aguas costeras del mar peruano. La determinación taxonómica de esta especie se realizó mediante microscopia de luz, electrónica de barrido y contraste interferencial diferencial (DIC). La fórmula tecal encontrada fue: pp, 3', 2a, 7'',5c, 5"' y 2''' 4s. Blixaea quinquecornis fue registrada en las bahías Sechura, Miraflores y Paracas entre el 2014 y 2017, usualmente con altas densidades de 3.2 x105 cel.L-1 (Miraflores) y 2.11x105 cel.L-1 (Paracas) en verano y 4.11 x104 (Paracas) en otoño 2016. Blixaea quinquecornis estuvo alternando con floraciones algales del dinoflagelado atecado Akashiwo sanguinea. El florecimiento de B. quinquecornis se observó con TSM entre 18.5 a 26.6 °C, salinidades entre 34.70 y 35.32 ups, pH entre 7.32 y 8.82 y oxígeno disuelto entre 3.8 y 12.5 mL/L. En Bahía Miraflores, la floración de B. quinquecornis fue asociado positivamente con el incremento de la TSM, salinidad y negativamente con la concentración de nitratos, mientras que las floraciones algales de A. sanguinea se correlacionó positivamente con la concentración de fosfatos y oxígeno disuelto. El registro de la floración de B. quinquecornis en las bahías de Miraflores y Paracas, coincidió con eventos de inusual calentamiento del mar asociado con el evento cálido El Niño 2015-2016.


Abstract In the present work, harmful algal blooms of the dinoflagellate Blixaea quinquecornis (Abé) Gottschling, 2017 are recorded for the first time for coastal waters of the Peruvian sea. The taxonomic determination of this species was done with light microscopy, Scanning Electron Microscopy (SEM), and Differential Interference Contrast (DIC) microscopy. The thecal formula is: pp, 3', 2a, 7'', 5c, 5"' and 2''' 4s. Blixaea quinquecornis was recorded in Sechura, Miraflores and Paracas bays between 2014 - 2016, mainly with algal blooms of 3.2 x105 cel.L-1 (Miraflores) and 2.11x105 cel.L-1 (Paracas) and 4.11 x104 cel.L-1 (Paracas) in autumn of 2016. Blixaea quinquecornis was found alternating with algal bloom produced by the athecate dinoflagellate Akashiwo sanguinea. The physicochemical variables associated with the bloom of B. quinquecornis were SST (18.5 to 26.6° C), salinities (34.7 to 35.325), pH (7.32 to 12.5), and dissolved oxygen (3.8 to 12.5 mL/L). The bloom of B. quinquecornis in Miraflores Bay was positively associated with the increase in SST, salinity and negatively with the concentration of nitrates, whereas the algal blooms of A. sanguinea were positively correlated with the concentration of phosphates and oxygen. The record of the bloom of B. quinquecornis in the 3 bays coincided with unusual sea warming event associated with the El Niño phenomenon 2015-2016.

ABSTRACT

Estádios periféricos como o Castor Cifuentes/MG e o Farião/MG, com capacidade inferior a 10 mil presentes, representam 77,4% do total de estádios brasileiros. Objetivamos aqui analisar a percepção que os torcedores de estádios periféricos têm sobre estádios e arenas. Para tanto, realizamos 19 incursões a campo, todas em dias de jogos. Para busca dos dados utilizamos a observação não participante e aplicação de formulários. Os dados foram analisados através do programa de análises estatísticas Statistical Package for the Social Sciences (SPSS) e da análise de conteúdo. Ao fim, participaram do estudo 107 torcedores. Os resultados obtidos evidenciaram que os participantes são favoráveis a tais transformações, mesmo cientes dos pontos negativos. Inclusive do risco de serem excluídos da vivência cotidiana nos estádios.


Peripheral stadiums like Castor Cifuentes/MG and Farião/MG, with a capacity below 10.000 people, represent 77.4% of the total Brazilian stadiums. We aim here to analyze the perception that fans who go to peripheral stadiums have of bigger stadiums and arenas. To do so, we conducted 19 visits to the stadiums, all on game days. Data were collected through non-participant observation and application of forms. Data were analyzed through the statistical analysis program Statistical Package for Social Sciences (SPSS) and content analysis. We had the participation of 107 individual fans. The main results show that fans are in favor of the changes even though they are aware of the negatives, including the risk of being hindered of frequent active life in stadiums.

ABSTRACT

BACKGROUND: The sabellid genera Anamobaea Krøyer, 1856 and Notaulax Tauber, 1879 are two of the most attractive polychaete worms in coral reefs. Anamobaea is represented by two Caribbean species and Notaulax with 24 species from around the world, six of them previously known to tropical America. During examination of fouling biota and sclerozoans from Mexico, Anamobaea orstedii Krøyer, 1856 was found in coral reefs from the southern Gulf of Mexico and three species of Notaulax were identified to the Mexican Pacific, two of them being new species to science. NEW INFORMATION: Anamobaea orstedii Krøyer, 1856 is first reported as sclerozoan of dead coral from the southern Gulf of Mexico. An amendment to the generic diagnosis of Anamobaea is provided, based on the presence of a higher number of skeletal cells than previously recorded; height, shape and exposition of the anterior peristomial ring; the non-fusion of dorsal collar margins to faecal groove; shape of collar chaetiger and abdominal chaetae and distribution and shape of radiolar ocelli. Notaulax californica (Treadwell, 1906) is reported as fouling in buoys and docks from the Gulf of California. Two new species of Notaulax are described: the former was found in hull and dock fouling from La Paz (Gulf of California) and the second one as sclerozoan of oysters from a dock fouling in Acapulco (south Mexican Pacific). In addition, reproductive features are described for the first time for A. orstedii which is a simultaneous hermaphrodite with female and males gametes found within the same segments of abdominal region. Oocytes develop synchronously and sperm morphology (spherical nucleus and rounded acrosome, four spherical mitochondria and a long free flagellum) suggest an adaptation to broadcast spawning and external fertilisation. Species of Notaulax here examined were gonochoric, with gametes distributed in abdominal segments.

ABSTRACT

Spinocerebellar ataxia type 3, or Machado-Joseph disease (SCA3/MJD), is caused by an expansion of CAG repeats, which is inversely correlated to age at onset (AO) of symptoms. However, on average, just 55.2% of variation in AO can be explained by expansion length. Additional modulators, such as polymorphic CAG tract in ATXN2 gene, can raise to 63.0% of the variation in AO. A sequence variation (rs3512) in FAN1 gene has previously been shown to be associated with late AO in Huntington's disease and polyglutaminopathies associated to ataxia. In the present study, genotype frequency of rs3512 was demonstrated in a cohort of SCA3/MJD patients from South Brazil, and these data were correlated to AO. The disease started 2.44 years earlier in subjects with the G/G genotype when compared to those subjects carrying the same CAGexp length at the ATXN3 gene and other genotypes (C/G and C/C) at rs3512. Placing together data on rs3512 genotype with data on CAG tract in ATXN2, AO of patients with G/G genotype was 2.58 years earlier, and a delay of 4.25 years was observed in patients that carry a short ATXN2 allele. Data presented here add further insights on the contribution of other factors in AO of SCA3/MJD beyond the causal mutation. Thus, well-known modifiers can help to unveil new ones and, as a whole, to better elucidate the mechanisms behind disease onset.

ABSTRACT

In recent years, site-specific spraying methods, which are capable of combining the image processing technologies with electronic and information technologies, have been started to be used in the weed control and target-oriented spraying. In this study, in addition to the site-specific spraying in laboratory conditions; a mobile spraying system, which can also perform broadcast application as a reference method, was set up. The spraying performance of the mobile system was tested for three different nozzle types (standard flat fan nozzle, cone nozzle, air induction nozzle) and at speeds of 0.48, 0.60, 0.72 and 0.84 km h-1. The mobile system was operated as both broadcast and site-specific for each nozzle type and travel speed. Three artificial weed samples were used at 75 cm intervals as sampling surfaces on the movement of the mobile system in the spraying operations; filter papers (FP) and water-sensitive papers (WSP) were placed behind them on the bars. While deposition values were measured with the filter papers, water-sensitive papers were used to measure the coverage rates. The spray distribution of the site-specific method in comparison with the reference method was investigated. According to the results, site-specific spraying applications did not cause any negative impact on depositions and coverage rates. The nearest results compared with the broadcast spraying were obtained with the air induction nozzle type at a speed of 0.48 km h-1 with a 60.5% deposition amount and 95.9% coverage rate.(AU)


Nos últimos anos, começaram a ser utilizados métodos de pulverização específicos do local, capazes de combinar as tecnologias de processamento de imagem com as tecnologias eletrônicas e de informação, no controle de ervas daninhas e na pulverização orientada para o alvo. Neste estudo, além da pulverização específica do local em condições de laboratório; foi instalado um sistema de pulverização móvel, que também pode executar a aplicação de transmissão como método de referência. O desempenho de pulverização do sistema móvel foi testado para três tipos diferentes de bicos (bico de ventilador plano padrão, bico de cone, bico de indução de ar) e nas velocidades de 0,48, 0,60, 0,72 e 0,84 km h-1. O sistema móvel foi operado como broadcast e específico do local para cada tipo de bico e velocidade de deslocamento. Três amostras de plantas daninhas artificiais foram usadas em intervalos de 75 cm como superfícies de amostragem no movimento do sistema móvel nas operações de pulverização; papéis de filtro (FP) e papéis sensíveis à água (WSP) foram colocados atrás deles nas barras. Enquanto os valores de deposição foram medidos com os papéis de filtro, papéis sensíveis à água foram usados para medir as taxas de cobertura. A distribuição de spray do método específico do local em comparação com o método de referência foi investigada. De acordo com os resultados, as aplicações de pulverização específicas do local não causaram impacto negativo nos depoimentos e nas taxas de cobertura. Os resultados mais próximos comparados com a pulverização por difusão foram obtidos com o tipo de bico de indução de ar a uma velocidade de 0,48 km h-1 com uma quantidade de deposição de 60,5% e taxa de cobertura de 95,9%.(AU)

ABSTRACT

Manual backpack sprayers are widely used in rural properties in Brazil. However, studies that assess their working characteristics, especially spray tip models and working pressure conditions, are scarce. Thus, the aim of this study was to assess how much the working pressure and spray tips influence the distribution quality of phytosanitary spray solutions in manual backpack sprayers. Four spray nozzles (standard flat-fan Magnojet TP11002, turbo flat-fan TeeJet TT11002, hollow-cone TeeJet TXA8002, and disc-core) were assessed in a patternator table at 1, 2, 3, and 4 bar. Analyses of spray distribution profile were performed by symmetry and the coefficient of variation (CV) analysed by the Tukey's test (p < 0.05). Spray tip models and working pressure influenced in more than 100% the distribution uniformity values of spray solution and in about 50% the useful range of the phytosanitary treatment. Among the models assessed in this study, the turbo flat-fan spray nozzle presents the best set of characteristics to be indicated for manual backpack sprayers aiming at field phytosanitary treatments.(AU)


O uso de pulverizadores costais manuais no Brasil é amplamente disseminado em propriedades rurais. Entretanto, são escassos os trabalhos de pesquisa que avaliem as suas características de trabalho, sobretudo modelos de ponta de pulverização e condições de pressão de trabalho. Desta forma, o objetivo deste trabalho foi avaliar quanto os modelos de pontas e a pressão de trabalho influenciam na qualidade da distribuição de caldas fitos-sanitárias com pulverizadores costais manuais. Foram avaliados em mesa de deposição quatro modelos de pontas de pulverização (jato plano convencional Magnojet TP 11002; jato plano defletor Teejet TT 11002; jatos cônicos vazios TeeJet TXA 8002 e "chapinha" original), a 1, 2, 3 e 4 bar de pressão. As análises do perfil de distribuição dos jatos foram realizadas por simetria e o coeficiente de variação analisado pelo teste de Tukey (p < 0,05). Os modelos de pontas de pulverização e a pressão de trabalho influenciaram em mais de 100% os valores de uniformidade de distribuição da calda, e cerca de 50% na largura da faixa útil de tratamento fitos-sanitário. Dentre os modelos avaliados neste trabalho, o de jato defletor é o que apresenta o melhor conjunto de características para ser indicado a equipar os pulverizadores costais manuais para os tratamentos fitossanitários de campo.(AU)

ABSTRACT

The complex geological and ecological processes that have generated high levels of biodiversity and endemism in the Baja California Peninsula have been the subject of intensive study. However, relatively little is known about phylogeography of the iconic endemic palm species of this region. We therefore analyzed a total of 2,294 bp of chloroplast and 738 bp of nuclear sequence data in 169 samples of five native palm species from Baja California, Sonora and Guadalupe Island. We found that Washingtonia and Brahea palms had low levels of genetic diversity and were highly structured, with the majority of species and major geographic regions being characterized by distinct haplotypes. We also found strong support for currently recognized species in Washingtonia, but our results were less clear cut for Brahea due to haplotype sharing. Furthermore, patterns of population structure were broadly consistent with historical vicariant events such as the inundation of the Isthmus of La Paz, the formation of the Sea of Cortez, and the more recent colonization and isolation of Guadalupe Island's palms. Our findings contribute toward a growing appreciation of the complexity of plant responses to past geological changes and also provide valuable baseline genetic data on relict American palm species.

ABSTRACT

Objetivo: O IV Consenso Brasileiro para Pesquisa de Autoanticorpos em Células HEp-2 (FAN) realizado em Vitória (ES), no dia 18 de setembro de 2012, objetivou discutir estratégias e recomendações relacionadas ao procedimento técnico, à padronização e à interpretação dos resultados da pesquisa de autoanticorpos em células HEp-2. Métodos: Participaram do evento 23 pesquisadores e especialistas de Universidades e laboratórios brasileiros. Foram abordados diferentes tópicos, discutidos amplamente a fim de se estabelecer recomendações específicas. Resultados e conclusão: O IV Consenso integrou à árvore de decisão o padrão citoplasmático em Anéis e Bastões, o padrão nuclear pontilhado Quasi-homogêneo (QH) e o padrão misto CENP-F. Discutiu-se ainda a necessidade de atenção para a classificação do padrão misto relacionado à presença de anticorpos anti-DNA topoisomerase I (Scl70), compreendendo os componentes nuclear pontilhado fino, nucleolar homogêneo, NOR na placa metafásica e citoplasmático pontilhado fino. Foram sugeridas diretrizes para o controle de qualidade do teste, diluição de triagem e diluição de esgotamento, e foi emitido alerta quanto à necessidade de atenção em relação à heterogeneidade de substratos disponíveis no mercado e a utilização de metodologias automatizadas para detecção de autoanticorpos. .


Objective: The Fourth Brazilian Consensus for Autoantibodies Screening in HEp-2 Cells (ANA) was held in Vitória, Espírito Santo, and aimed to discuss strategies and recommendations about the technique, standardization, interpretation and quality control of the indirect immunofluorescence reaction on HEp-2 cells. Methods: Twenty three ANA experts from university centers and private laboratories in different areas from Brazil discussed and agreed upon recommendations for the fourth edition of the Brazilian Consensus for Autoantibodies Screening in HEp-2 Cells. Results and conclusion: The 4th ANA Consensus included three novel patterns into the existing algorithm (cytoplasmic Rods and Rings, nuclear Quasi-homogeneous, and CENP-F). Emphasis was given to the need of attention in describing the peculiar mixed pattern elicited by anti-DNA topoisomerase I (Scl-70) autoantibodies, comprising nuclear fine specked, nucleolar homogeneous pattern, NOR staining in metaphase plates, and cytoplasmic fine speckled patterns. The group also emphasized the need for continuous quality control in indirect immunofluorescence assays, the establishment of screening dilutions, as well as conjugate titration. An alert was made regarding the heterogeneity of commercial kits in defining patterns and the use of solid phase methodologies to determine the presence of autoantibodies. .

ABSTRACT

The Neotropical palm swift, Tachornis squamata Cassin, 1853 (Apodidae), inhabits palm forests in the northern, northeastern and central regions of South America. At the Chapada do Apodi, Brazilian Caatinga, we investigated how the Neotropical palm swifts use palm trees to roost in two areas: urban and exurban. From May to November 2011 and from March to June 2012, out of the breeding season of the species, we compared the differences between the descriptive parameters of the palm-roosts and the activity levels of the swifts in urban and exurban roosting. We sampled 30 carnauba palm-roosts in exurban areas and 32 carnauba palm-roosts and 26 Chinese fan palm-roosts in urban areas for a period of 132 days, a total of 528 hours of sampling. The number of wasp nests was greater in carnauba palm-roosts in exurban areas than in palm-roosts in urban areas. However, there were greater numbers of swift nests and swifts in palm-roosts in urban areas than in exurban areas. Moreover, the activity levels (number of entry and exit events of swifts in the palm-roost) during sunrise (05:00-05:20 a.m.) and sunset (05:41-06:00 p.m.) were significantly lower in the exurban area than in the urban area. These results may contribute to establish better management practices for the coexistence between wildlife and humans in cities.

ABSTRACT

The Neotropical palm swift, Tachornis squamata Cassin, 1853 (Apodidae), inhabits palm forests in the northern, northeastern and central regions of South America. At the Chapada do Apodi, Brazilian Caatinga, we investigated how the Neotropical palm swifts use palm trees to roost in two areas: urban and exurban. From May to November 2011 and from March to June 2012, out of the breeding season of the species, we compared the differences between the descriptive parameters of the palm-roosts and the activity levels of the swifts in urban and exurban roosting. We sampled 30 carnauba palm-roosts in exurban areas and 32 carnauba palm-roosts and 26 Chinese fan palm-roosts in urban areas for a period of 132 days, a total of 528 hours of sampling. The number of wasp nests was greater in carnauba palm-roosts in exurban areas than in palm-roosts in urban areas. However, there were greater numbers of swift nests and swifts in palm-roosts in urban areas than in exurban areas. Moreover, the activity levels (number of entry and exit events of swifts in the palm-roost) during sunrise (05:00-05:20 a.m.) and sunset (05:41-06:00 p.m.) were significantly lower in the exurban area than in the urban area. These results may contribute to establish better management practices for the coexistence between wildlife and humans in cities.
