As an alternative to the International Organization for Standardization (ISO) method 22866, a method for the field measurement of spray drift was developed in the Department of Agricultural, Forestry and Environmental Economics and Engineering of the University of Turin, Italy. This new method, termed “test bench,” can be applied for wind conditions beyond those covered in ISO 22866. The aim of this study was to quantify the drift potential of three nozzles at two working pressures and two sprayer boom heights using the test bench method, under subtropical climate conditions. The experiment was conducted at Bandeirantes, Paraná State, Brazil, from 2018 to 2019 in a completely randomized design with 12 treatments, wherein three nozzles were used at the minimum and maximum working pressures, and two boom heights were tested, with four replicates for each combination. The following nozzles were used: XR11002 (100 and 400 kPa), AIXR11002 (100 and 600 kPa), and ATR 2.0 (400 and 2000 kPa), operating at boom heights of 0.50 and 1.00 m. The test bench method allows for drift assessment under subtropical climate conditions, and the results revealed that changes in meteorological conditions, nozzles, and pressure are key factors affecting the drift potential of boom sprayers. Relative air humidity and working pressure were the most important determining factors of the drift potential of the nozzles, whereas boom height had no effect on drift potential.

Pratylenchus brachyurus causes serious damage to soybean production and other crops worldwide. Plant molecular responses to RLN infection remain largely unknown and no resistance genes have been identified in soybean. In this study, we analyzed molecular responses to RLN infection in moderately resistant BRSGO (Chapadões—BRS) and susceptible TMG115 RR (TMG) Glycine max genotypes. Differential expression analysis revealed two stages of response to RLN infection and a set of differentially expressed genes (DEGs) in the first stage suggested a pattern-triggered immunity (PTI) in both genotypes. The divergent time-point of DEGs between genotypes was observed four days post-infection, which included the activation of mitogen-activated protein kinase (MAPK) and plant–pathogen interaction genes in the BRS, suggesting the occurrence of an effector-triggered immunity response (ETI) in BRS. The co-expression analyses combined with single nucleotide polymorphism (SNP) uncovered a key element, a transcription factor phytochrome-interacting factor (PIF7) that is a potential regulator of moderate resistance to RLN infection. Two genes for resistance-related leucine-rich repeat (LRR) proteins were found as BRS-specific expressed genes. In addition, alternative splicing analysis revealed an intron retention in a myo-inositol oxygenase (MIOX) transcript, a gene related to susceptibility, may cause a loss of function in BRS.
The present study observed significant effects of whole-body vibration (WBV) on bone mineral density (BMD) in postmenopausal women, with high-quality evidence for high-frequency, low-magnitude, and high-cumulative-dose use. The aim was to update a previous systematic review with meta-analysis to observe the effects of WBV on BMD in postmenopausal women. For the meta-analysis, the weighted mean difference between WBV and control groups, or WBV and conventional exercise, was used for the area of bone mineral density (aBMD) of the lumbar spine, femoral neck, total hip, trochanter, intertrochanter, and Ward’s area, or volumetric trabecular bone mineral density (vBMDt) of the radius and tibia. Methodological quality was assessed using the PEDro scale and the quality of evidence using the GRADE system. In total, 23 studies were included in the systematic review and 20 in the meta-analysis. Thirteen studies showed high methodological quality. WBV compared with control groups showed significant effects on aBMD in the primary analysis (lumbar spine and trochanter), sensitivity (lumbar spine), side-alternating vibration (lumbar spine and trochanter), synchronous vibration (lumbar spine), low frequency and high magnitude (lumbar spine and trochanter), high frequency and low magnitude (lumbar spine), high frequency and high magnitude (lumbar spine, trochanter, and Ward’s area), high cumulative dose and low magnitude (lumbar spine), low cumulative dose and high magnitude (lumbar spine and trochanter), and positioning with semi-flexed knees (trochanter). Of these results, only high frequency associated with low magnitude and high cumulative dose with low magnitude showed high-quality evidence. At this time, considering the high quality of evidence, it is possible to recommend WBV using high frequency (≈ 30 Hz), low magnitude (≈ 0.3 g), and high cumulative dose (≈ 7000 min) to improve lumbar spine aBMD in postmenopausal women. Other parameters, although promising, need to be better investigated, considering, when applicable, the safety of the participants, especially in vibrations with higher magnitudes (≥ 1 g).
Objetivo: analisar a prevalência e causas da mortalidade neonatal no Brasil. Método: estudo transversal dos óbitos neonatais ocorridos de 2010 a 2019. Foram utilizados registros do Sistema de Informação sobre Nascidos Vivos e do Sistema de Informação sobre Mortalidade. As análises ocorreram por meio de frequências absolutas e relativas. Resultados: ao analisar a prevalência da mortalidade neonatal no Brasil, percebe-se grande diversificação no coeficiente nas diferentes regiões brasileiras. Embora houve redução no período, notam-se flutuações, com coeficientes maiores para região nordeste. A maior proporção dos óbitos ocorrem por causas perinatais, os quais, na grande maioria são evitáveis. Conclusão: o estudo permitiu observar que apesar dos avanços no atendimento pré-natal e ao recém nascido, ainda prevalecem coeficientes significativos de mortalidade neonatal, tendo como causas principais as perinatais e malformações congênitas. Por outro lado, os dados permitem sinalizar regiões com proporções elevadas, possibilitando um planejamento regional mais efetivo.
Respiratory tract diseases are responsible for major economic losses in the poultry industry. Avian metapneumovirus is a pathogen that causes acute infections in the upper airways of turkeys and chickens, is associated with Swollen Head Syndrome, and generates variable morbidity between 1% and 20% in chickens. Turkey Rhinotracheitis has a morbidity of up to 100%. The frequent presence of secondary agents or infections associated with other microorganisms can aggravate the syndrome. The clinical diagnosis itself is not sufficient to determine metapneumovirus infections since the disease can be confused with other respiratory problems. Serological methods such as seroneutralisation, immunofluorescence and ELISA, immunohistochemistry, virus isolation from embryonated eggs or tissue cultures and PCR are the main techniques used in the diagnosis of avian metapneumovirus infections. Therefore, a laboratory diagnosis confirming the presence of this pathogen is necessary. Currently, several methods are available, with varying applications and sensitivity. This work describes the current diagnostic methods and presents their advantages and limitations.
This article examines the very atypical case of epagoge in Prior Analytics II, 23, aiming to situate it in the general framework of Aristotle’s conception of induction and in his epistemology. Besides offering a translation and a detailed commentary of the chapter, I have reassembled some of the main theories that support its character of exception – as if the philosopher were defending the existence of a “complete induction” – and then I close the article by refuting such theories, supported by other texts, such as Topics I, 8, and Posterior Analytics I, 5.
The purpose of this paper is to determine the ocular echobiometry and investigate its correlation with cranial and body morphometric parameters in 50 adult Shih Tzu dogs. The echobiometric measurements of the anterior chamber (AC), vitreous chamber (VC), lens axial thickness (LTA), transverse lens thickness (LTT), and axial length of the eyeball (ALE) were obtained by two-dimensional ultrasonography. Morphometric measurements of bizygomatic distance (BDIST), frontal-occipital distance (FOD), withers height (WH), thoracic circumference (TC), and body length (BL) were also obtained. The mean of the AC depth was 2.83±0.50mm, the VC was 9.18±0.54mm, the LTA was 6.42±0.32mm and the LTT was 9.17±1.18mm, while the mean of the ALE was 18.82±0.66mm. There was no correlation between ocular echobiometric variables and cranial and body morphometric variables in adult dogs of the Shih Tzu breed, as well as no significant difference of these variables when considering gender and age of the dogs (p ≥ 0.05). Keywords: canines; biometrics; ultrasonography; ocular anatomy; ophthalmology
Resumo A investigação que apresentamos neste artigo foi realizada no ano de 2019, junto aos alunos do terceiro ano do curso de licenciatura em história da Universidade Estadual de Londrina (Paraná, Brasil) e do mestrado em ensino de história da Universidade do Minho, na cidade de Braga (Portugal), e abordou o significado do estágio supervisionado para a formação dos professores de história. Defendemos que a disciplina se constitui no campo de diálogo entre a epistemologia da história e os procedimentos de ensino baseados na ciência da história. Neste texto, optamos por explorar um questionário aplicado às duas realidades com questões que dão face ao significado da história, de ser professor de história e da experiência vivenciada durante a implementação dos projetos de ensino nas regências realizadas dentro de escolas de rede pública dos dois países. A pesquisa nas duas instituições deu-se por duas razões principais: primeiro, por considerarmos que nessas instituições há um aprimoramento na formação de professores de história, traduzida por um modelo de estágio supervisionado com características de vanguarda, cuja realização se reflete em pesquisas que provocam a percepção da importância das práticas educativas supervisionadas; e, segundo, pelo fato de as experiências traduzidas nas entrevistas auxiliarem na compreensão deste momento como base epistemológica imprescindível para formação de professores.
The study presented in this article was carried out in 2019 with students from the third year of the History course at the State University of Londrina/Paraná/Brazil, and the students from the Master’s Degree in History Teaching at the University of Minho, in the city of Braga in Portugal, and addressed the meaning of the Supervised Practice for the training of History teachers. The discipline is formed within the field of dialogue between the epistemology of History and teaching procedures based on the science of History. In this text, we chose to explore a questionnaire applied to the two realities with questions that face the meaning of History, of being a History teacher and the experience lived during the implementation of teaching projects in the regencies carried out within public schools in both countries. The research in both institutions took place for two main reasons: first, because we consider that in these institutions there is an improvement in the training of History teachers, translated into a model of Supervised Practice with avant-garde characteristics, whose accomplishment is reflected in research that provokes the perception of the importance of supervised educational practices, and, second, because the experiences translated in the interviews will help understanding this moment as an essential epistemological basis for teacher training.
Introduction: Low back pain (LBP) is a major cause of physical disability in the world. The origin of this condition can be due to differents causes, with a specific cause or of unknown mechanical origin,being characterized as unspecific. In this case a physical therapy treatment approach with manual therapy is relevant, which includes the Muscle Energy Technique (MET) classified as a common conservative treatment for pathologies of the spine, mainly in LBP and disability. This study assessed the effectiveness of the muscle energy technique on nonspecific low back pain. Evidence acquisition: Patients with acute, subacute or chronic non-specific low back pain. The primary outcomes were pain and disability. This study was designed by a systematic review and meta-analysis, registered in PROSPERO (CRD42020219295). For the report and methodological definitions of this study, the recommendations of the PRISMA protocol and the Cochrane collaboration, were followed, respectively. Evidence synthesis: The search yielded 164 citations, which 19 were eligible randomised trials were included in the review (n = 609 patients with low back pain). The methodological quality of the studies averaged 4.2 points, with an interval of 2 to 7 points. Three RCTs showed satisfactory methodological quality (PEDro score ≥6). For patients with chronic LBP, a significant result on pain (but with a small and clinically unimportant effect) in favor of MET versus other (MD =-0.51 [95% CI,-0.93 to -0.09] p=0.02, n=376, studies=11, I2=80%). In patients with subacute LBP, MET enabled a significant and moderate effect to reduce pain intensity when compared to the control group (MD =-1.32 [95% CI,-2.57 to -0.06] p = 0,04, n= 120, studies=3, I2=88%). No significant effects were observed for the disability. Conclusions: MET is not considered an efficient treatment to improve the incapacity of the lumbar spine, but it may be beneficial in reducing the intensity of LBP, although showing a small clinical effect in chronic LBP and a moderate effect in subacute LBP.
Titanosaurian sauropods are known to exhibit remarkable body size disparity, with some taxa famed for nearing the zenith of terrestrial vertebrate body size. Here, we describe a new titanosaurian – Ibirania parva gen. et sp. nov. – from the Upper Cretaceous (Santonian– Campanian) São José do Rio Preto Formation of Bauru Basin, in which represents one of the smallest sauropods known to date. The new taxon is diagnosed by seven autapomorphies and had an estimated body length of 5.7 m. Histological and μCT scan analyses showed that this new taxon is represented by skeletally mature individuals, which had attained somatic maturity prior to death. Phylogenetic analyses recovered the new taxon deeply nested within Saltasaurinae, a clade previously known by small-sized forms. Ibirania parva gen. et sp. nov. brings new information indicating that the body size reduction in some titanosaurians could be driven by recurrent ecophysiographical settings, present in South America prior to the diversity peak attained by the group during the Campanian–Maastrichtian.
Background: The burnout syndrome can be avoided and/or have its signs and symptoms reduced by knowing the five associated factors that help identify the health and working conditions of the professors of graduate programs. Objective: To analyze the factors associated with burnout among faculty members of graduate stricto sensu programs. Design and setting: A cross-sectional study was conducted among 585 faculty members of Graduate Programs in Language Teaching and Linguistics in Brazil. Methods: Data were collected through an online questionnaire. The outcomes were the dimensions of burnout and its related factors identified through multiple templates of logistic regression. Results: Faculty members with increased chances of emotional exhaustion and depersonalization mentioned the use of medications due to labor activities. The negative influence of pace and intensity of work, thoughts about quitting the program, and having to produce three or more scientific articles were associated with higher chances of emotional exhaustion, while having to achieve nine hours per week in undergraduate programs was related to reduced personal accomplishment. Having a conjugal relationship, satisfaction with health and work, post-doctoral degree, autonomy, and good interpersonal relationships with faculty members of the program reduced the chances of emotional exhaustion. Reduced chances of depersonalization occurred among those who were satisfied with work, had good interpersonal relationships with advisees and faculty members, and received productivity funding. Conclusion: Sociodemographic, health, and occupational factors related to the dimensions of burnout were identified.
Sugarcane bagasse ash is a by-product produced by the energy cogeneration from biomass burning. Different processes can be applied to this material to adapt its chemical and physical characteristics to its use as pozzolan. This work aims to evaluate the effectiveness of the densimetric fractionation process in production of sugarcane bagasse ash with high pozzolanicity. Initially, a quartz-rich ash was collected in an industrial boiler and subjected to densimetric fractionation to remove the quartz particles through decantation. Then, the potentially pozzolanic ash portion was subjected to ultrafine grinding. The results showed high amorphous content (94.8%) in the ash after fractionation. Electrical conductivity and performance index tests confirmed the adequate pozzolanicity of the processed ashes. In addition, cement-based pastes with 20% cement replacement by bagasse ash (in mass) showed a reduction in the heat of hydration. Thus, the densimetric fractionation was efficient in producing a material with high reactivity compared to the original ash due to the reduction of contaminants and, consequently, the increase in the amorphous silica concentration.
The tobacco budworm Chloridea (Heliothis) virescens (F.) (Lepidoptera: Noctuidae) has been recently reported in corn crops. However, there is no information regarding the biology of this species feeding on corn cobs. Additionally, the relationship between temperature and tobacco budworm feeding habits is important to project the adaptation of the insect in corn crops at different times and regions. This study aimed to investigate the development of C. virescens feeding on corn cobs, under controlled laboratory conditions, at three temperatures (25 ± 1 ºC, 28 ± 1 ºC and 31 ± 1 ºC). Although adult budworms were observed at all temperatures, the larval development period was reduced at 31 ± 1 ºC, resulting in a lower grain consumption. On the other hand, biological parameters such as larval and pupal viability, pupal weight and sex ratio did not vary with temperature. During the adult stage, a similar fecundity was recorded at all temperatures; however, the egg viability was zero. The optimal temperature for the C. virescens development was between 25 ± 1 ºC and 28 ± 1 ºC. The temperature of 31 ± 1 ºC affects the eggs development, preventing the next generation of tobacco budworms. KEYWORDS Chloridea (Heliothis) virescens (F.); Heliothinae; corn pest; global warming
Cognitive sciences and neurosciences have advanced enormously during the last decades not only in the understanding of how mind and brain work but also in how that knowledge can be considered to improve educational practice. However, most of the evidence in this issue came from Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. Thus, there is not much information about how the integration of cognitive sciences and neuroscience could impact education in non-WEIRD populations, which are by far the biggest. This chapter introduces a book addressing how non-WEIRD societies’ research developments in cognitive science and neuroscience can impact education; in other words, this chapter introduces the central concepts to understand the interaction between cognitive science and education in cultural and social contexts that are quite unknown, mainly in Latin America. Also, this chapter provides an outline of the book that serves as a guide for reading it.KeywordsCognitive ScienceNeuroscienceEducationLatin AméricaNon-WEIRD societies
Students often adopt learning strategies that are suboptimal for memory retention, as reading multiple times the to-be-learned materials, for example. A more effective approach consists in trying to remember the materials after studying them, a strategy known as “retrieval practice.” Retrieval practice can be administered through various types of quizzes, tests, and exercises, and has shown to be beneficial for learning in laboratory contexts as well as in real classroom environments. Importantly, however, most studies demonstrating the benefits of retrieval practice involved college students from WEIRD populations. Thus, our goal here was to review studies on retrieval practice that focused on diverse populations (e.g., non-WEIRD students, elementary school children, students with special educational needs). Although the number of studies on retrieval practice involving these populations remains considerably low, their results are in general positive, and therefore favorable to the adoption of this strategy to benefit learning in these populations.KeywordsLearningMemoryLearning strategiesRetrieval practiceEducation
Objective: to assess the effectiveness of the interventions targeted at preventing and reducing the workplace violence suffered by health and support professionals. Method: a systematic review with meta-analysis conducted in eight databases and in the gray literature. Risk of bias was assessed by means of the Cochrane tools and certainty of the evidence, through Grading of Recommendations Assessment, Development and Evaluation. The analysis was performed in a descriptive manner and through the meta-analysis, including a heterogeneity assessment. Results: a total of 11 randomized and quasi-randomized studies were eligible, of which six (54.5%) implemented individual skills, four used a multiple approach (36.4%) and one (9.1%) resorted to governmental actions. Four studies (36.4%) exerted a positive and significant effect on reducing violence. Risk of bias was classified as high or uncertain. The meta-analysis was performed with two studies that tested individual skill (intervention group) versus individual skill (comparator group), although there was no scientific evidence (95% CI: -0.41 - 0.25, p=0.64) for the violence prevention/reduction outcome. Conclusion: this review did not obtain a high level of evidence in the prevention or reduction of workplace violence. The reduced number of randomized trials, the lack of studies with low risk of bias and the high consistency may have been factors that hindered recommending effective interventions.
This trial aims to investigate the effects of the ActTeens physical activity program, on adolescents’ physical activity level, health-related fitness, cardiometabolic and mental health. The trial will aim to recruit ~140 adolescents (aged 13–14 years). Participants will be randomized into either intervention or control groups. The intervention will be guided by social cognitive theory and self-determination theory and implemented over one school term (24-weeks). The ActTeens Program will include: (1) structured physical activity sessions delivered within physical education, including movement-based games and dynamic stretching warm-ups; resistance training skill development; high-intensity training workouts; and cool-downs; (2) self-monitoring plus goal setting for physical activity by pedometer-smart wearable; and (3) healthy lifestyle guidance (social support) by WhatsApp® messages about healthy eating and regular physical activity for the intervention and parents groups. Study outcomes will be assessed at baseline, 24-weeks from baseline, and 12-months from baseline. Physical activity (accelerometer) is the primary outcome. Secondary outcomes include muscular and cardiorespiratory fitness, cardiometabolic profile, and mental health. A process evaluation will be conducted (i.e., recruitment, retention, attendance, and program satisfaction). This project will have the potential to address many questions and debates regarding the implementation of physical activity interventions in low-and- middle-income countries. Trial registration: ClinicalTrials.gov NCT05070377 . Registered on 7 October 2021.
Objective to expand the debate on factors present in the daily life of rural older adults in Brazil, which contribute to the increase in elder abuse (EA) in the pandemic. Method a theoretical-reflective study, which presents the Brazilian National Comprehensive Health Policy for Rural and Forest Populations and the Vulnerability Theory as frameworks, proposed by Ayres, that seek to understand the exposure of individuals to aggravating health outcomes. The development was based on national and international literature, and was organized by the guiding axis “vulnerabilities, formal and informal networks of protection against EA: reflections in times of the COVID-19 pandemic in a context of rurality”. Results the social distancing necessary for mitigating the COVID-19 pandemic may be negatively impacting rural older adults facing EA. It is believed that the set of strategies of formal and informal networks has not adequately met older adults’ needs in rural areas. Final considerations and implications for practice it is of fundamental importance that, amidst the coronavirus pandemic, strategies are implemented for maintenance and expansion of the formal and informal network social equipment of protection against EA, taking into account rural people’s needs.

In linguistic studies, it is common to call “Lexicon Sciences” the disciplines (especially Lexicology, Lexicography, and Terminology) that study the lexical units of the language. This article presents a proposal for a Lexicon Sciences Dictionary, to organize the terminology of this area of knowledge. The research was based on Corpus Linguistics (Berber Sardinha, 2004Berber Sardinha, T. (2004). Lingüística de Corpus. Manole.) and on the principles of Communicative Theory of Terminology (Cabré, 1999Cabré, M. T. (1999). La Terminologia: representación y comunicación. Elementos para una teoría de base comunicativa y otros artículos. Universitat Pompeu Fabra.). The corpus is composed by the production (articles, books, theses, and dissertations) of the 50 permanent members of GTLex (ANPOLL), published between 2000 and 2018 and available online. After analyzing a corpus of 580 files (more than 7 million tokens), a provisional nomenclature of 717 terms was elaborated. About 60% of the nomenclature is composed of complex terms, confirming the tendency of syntagmatic formation in terminologies because of the specification of knowledge.
