Abstract Haemulidae represents one of the most diverse, widespread and conspicuous families of Perciformes, in which most species are marine, some brackish and rarely from freshwater. From April 2009 to July 2012, 120 specimens of Conodon nobilis, 60 Orthopristis rubra and 50 Anisotremus virginicus were collected off the State of Rio de Janeiro, Brazil, and analyzed for metazoan parasites. A total of 16 parasite taxa were found on/in A. virginicus, 19 on/in Co. nobilis and 21 on/in O. rubra, in which ectoparasites were most common on A. virginicus and Co. nobilis and endoparasites in O. rubra. All parasites showed aggregate pattern of distribution (discrepancy index values higher than 0.70). Mean abundance, species richness and Brillouin index (diversity) differed among the host species, i.e., O. rubra showed the highest values, followed by A. virginicus and Co. nobilis with intermediate and lowest values, respectively. At infracommunity level was possible to observe high similarity of parasite composition among the three host species. The digeneans Leurodera decora and Monorchis latus, and the acanthocephalan Koronacantha sp. represent new locality records off Brazil. Moreover, five, four and two taxa are reported, for the first time, parasitizing Co. nobilis, A. virginicus and O. rubra, respectively. diverse Perciformes marine freshwater 200 2012 12 6 5 Janeiro Brazil 1 onin Co 2 O discrepancy 0.70. 070 0.70 . 0 70 0.70) abundance diversity (diversity ie i e i.e. respectively latus sp Moreover five reported time 20 201 07 0.7 7 i.e 0.

ABSTRACT This article aims to analyze militarized schools stemming from the 2019 National Civic-Military School Program. Documentary and bibliographic research on the topic was conducted to that effect. Intervention Bioethics provides methodological tools to analyze conflicts when Public Security acquires a role in schools. The discussion instrumentalizes the concepts of Coloniality of Power and Intervention Bioethics as critical tools. Unconstitutional in nature, the militarization of schools follows a political agenda that materializes in the curtailment of rights and a threat to education. It is concluded that the militarization experience promotes an increase in violence in the school environment instead of promoting a culture of peace. 201 CivicMilitary Civic Military Program effect nature education peace 20 2

ABSTRACT This research aimed to verify the effect of the COVID-19 pandemic on mental illness risk (MIR) and confirm the association of PA levels with MIR in elderly women during the COVID-19 pandemic. This experimental longitudinal study involved 44 elderly women aged 67.3± 5.3 years. The SRQ-20 and IPAQ were applied from February 2020 to February 2021, prior to the onset and during the pandemic. Significant increase (242%) of positive responses to MIR between the two periods (p= 0.002, February: 7 vs August: 17, (χ2 (1)= 8.51; p= 0.003, RR= 3.02). Regarding PA levels, there was a significant increase (566%) with a large effect size (ES) in the number of elderly women with low PA levels, from 3 in February to 20 in August, p= 0.0001, V= 1. There was a significant reduction (450%) with high ES of 18 elderly women with high levels of PA from February to 4 in August, p= 0.0001, V= 1. An inverse correlation was identified, with moderate ES between the levels of MIR and PA during the pandemic, r= -0.40, R2= 0.16. The COVID-19 pandemic caused an increase in the MIR of elderly women with a moderate inverse association with PA levels during the COVID-19 pandemic.

Abstract This study aimed to evaluate the effect of synchronization with prostaglandin F2α in Baixadeiro mares during the rainy and dry seasons. Fourteen mares were synchronized by administering two doses of 1 mL prostaglandin PGF 2α and monitored by rectal palpation and ultrasound for the assessment of follicular development and uterine echotexture. Of this total, nine mares allowed the collection of blood, in which the blood was collected by venipuncture of the jugular vein to determine progesterone (P4) by ELISA. Mares showed no differences (P > 0.05) in weight, body score condition (BSC), tone, uterine edema, frequency of ovulation, synchronization interval, estrus, and the total number of follicles between periods. However, there was a difference in large increased follicle diameter (P < 0.05) during the dry season. The average concentrations of P4 in mares differed (P < 0.05) between the pre- and post-ovulatory phases for both seasons and after ovulation, with higher concentrations in the rainy season. Furthermore, statistical differences in daily light (P < 0.05) were observed between the dry and rainy periods. Thus, we conclude that mares from the genetic grouping Baixadeiro showed no reproductive seasonality, though there was a difference in luminosity between the rainy and dry seasons. The treatment with two doses of PGF 2α was effective in synchronizing the mares, promoting the return of estrus in the dry and rainy periods. The mares remaining cyclically active throughout the year provided there were appropriate forage availability and quality levels to allow for normal values of body weight and condition.

Abstract: This study presents the experience of using Arduino and the platform Tinkercard for developing programming competencies in first-year students at the Continental University of Huancayo (Peru). The study is conducted online during the COVID-19 pandemic by using a simulator. The development of programming competencies is a fundamental and essential milestone for students enrolled in systems engineering, information science, computer science, and informatics degrees. For students, it is challenging to work with programming languages that require compliance with complex syntactic and semantic rules. The results show and demonstrate a positive impact on the development of students' skills when compared to previous courses. Development of basic skills is observed on digital circuits and computational electronics. It is concluded that students are highly comfortable with Arduino and Tinkercard, even though, due to the pandemic, the experiments are not performed physically.

ABSTRACT Background: Non-metastatic castration resistant prostate cancer (M0 CRPC) has seen important developments in drugs and diagnostic tools in the last two years. New hormonal agents have demonstrated improvement in metastasis free survival in M0 CRPC patients and have been approved by regulatory agencies in Brazil. Additionally, newer and more sensitive imaging tools are able to detect metastasis earlier than before, which will impact the percentage of patients staged as M0 CRPC. Based on the available international guidelines, a group of Brazilian urology and medical oncology experts developed and completed a survey on the diagnosis and treatment of M0 CRPC in Brazil. These results are reviewed and summarized and associated recommendations are provided. Objective: To present survey results on management of M0 CRPC in Brazil. Design, setting, and participants: A panel of six Brazilian prostate cancer experts determined 64 questions concerning the main areas of interest: 1) staging tools, 2) treatments, 3) side effects of systemic treatment/s, and 4) osteoclast-targeted therapy. A larger panel of 28 Brazilian prostate cancer experts answered these questions in order to create country-specific recommendations discussed in this manuscript. Outcome measurements and statistical analysis: The panel voted publicly but anonymously on the predefined questions. These answers are the panelists' opinions, not a literature review or meta-analysis. Therapies not yet approved in Brazil were excluded from answer options. Each question had five to seven relevant answers including two non-answers. Results were tabulated in real time. Conclusions: The results and recommendations presented can be used by Brazilian physicians to support the management of M0 CRPC patients. Individual clinical decision making should be supported by available data, however, for Brazil, guidelines for diagnosis and management of M0 CRPC patients have not been developed. This document will serve as a point of reference when confronting this disease stage.

Abstract Trachypus Klug is a Neotropical genus of crabronid wasps comprising 31 ground-nesting species. Its species can be solitary or communal, and two diet ranges are known: they can forage on several bee subfamilies and wasps; or can be specialists on stingless bees. Natural history observations are scarce nowadays but are essential to contextualize ecological and evolutionary studies. Here we report new records and give biological notes for Trachypus elongatus (Fabricius, 1804), Trachypus taschenbergiRubio-Espina, 1975, and Trachypus varius (Taschenberg, 1875). Observations and samplings were carried out twice a month, during one year in the city of Curitiba, southern Brazil. Besides field observations, circular statistics were used to analyze seasonality. All species nest in sloped soil and are solitary. Trachypus elongatus and T. taschenbergi were active during most of the year with marked seasonality in the late spring and early summer. Both species were observed hunting only stingless bees, with T. elongatus specialized on Trigona spinipes (Fabricius, 1793), and T. taschenbergi specialized on Paratrigona subnuda Moure, 1947 drones. Trachypus varius was observed only in January and one female was recorded foraging on a Paratrigona subnuda worker. Our observations provide additional data for understanding the biology of bee-hunting wasps, and this is the first study to bring information for T. taschenbergi and T. varius. Our data corroborate that some species of the genus Trachypus are specialized on stingless bees.

Resumo Objetivo Avaliar fatores preditivos de morte em pacientes de idade igual ou superior a 70 anos com fratura proximal do fêmur submetidos a tratamento cirúrgico. Métodos Análise de prontuários médicos criando-se uma coorte retrospectiva com seguimento de 6meses. Foramanalisados 124 prontuários após aplicação dos critérios de inclusão e exclusão. Todos os pacientes foram tratados por um único cirurgião ortopédico em condições de uniformidade. Resultados Taxa de mortalidade de 34.7%, sendo o perfil mais comum de paciente o indivíduo do gênero feminino, com 85 anos e ao menos 1 comorbidade. Os pacientes com idade superior a 85 anos, internação hospitalar por mais de 7 dias, ao menos 1 comorbidade presente e internação em centro de terapia intensiva (CTI) apresentaram maior risco de óbito (respectivamente 2; 2,5; 4 e 4 vezes maior). Conclusão Em relação ao desfecho óbito, apesar de não encontramos diferença estatisticamente significativa no que se refere à topografia da lesão e como essas se comportamnomomento em que coexistemjunto a internação em CTI, acreditamos na necessidade de maiores investigações sob essa ótica na população com o perfil estudado.

Abstract Objective To evaluate predictive factors of death in patients aged ≥ 70 years old with proximal femoral fracture (PFF) submitted to surgical treatment. Methods An analysis of medical records by creating a retrospective cohort with a 6- month follow-up. A total of 124 charts were analyzed after applying the inclusion and exclusion criteria. All of the patients were treated by a single orthopedic surgeon under uniform conditions. Results The mortality rate was of 34.7%, and the most common profile was female, 85 years old, and with at least 1 comorbidity. Patients > 85 years old, hospitalized for > 7 days, with at least 1 comorbidity, and staying at the intensive care unit (ICU) had a higher risk of death (2, 2.5, 4, and 4 times higher, respectively). Conclusion Regarding the death outcome, although we did not find a statistically significant difference in the topography of the lesion and in its behavior in its coexistence with ICU hospitalization, we believe that further investigations under this perspective are required in a population with the studied profile.

Resumo Justificativa: O reflexo trigêmino-cardíaco é um fenômeno fisiológico passível de ocorrer em cirurgias da cabeça e pescoço, e normalmente é benigno. Contudo, pode apresentar respostas exageradas, com grave morbidade. Relato de caso: Paciente masculino, 26 anos, candidato a tratamento cirúrgico de fratura do complexo zigomático-orbitário. Ato cirúrgico sem intercorrências com tamponamento nasal bilateral ao final. Após admitido na sala de recuperação pós-anestésica, queixou-se de “falta de ar” e náusea. A oximetria de pulso caiu abaixo 90% em ar ambiente e foi ofertado então O2 a 100% sob máscara de Hudson. Não houve melhora da oximetria e apresentou piora da dispneia, com sibilos difusos, redução da frequência cardíaca e da pressão arterial. Administrada atropina, que elevou a frequência cardíaca, mas sem resolução da hipotensão arterial e broncoespasmo. Aventamos a hipótese de reflexo trigêmino-cardíaco e então foi feita a remoção do tamponamento nasal com remissão completa dos sinais e sintomas. Discussão: Florian Kratschmer (1870) foi o primeiro a descrever as influências de reflexos da mucosa nasal na respiração e na circulação, o que ficou conhecido como reflexo de Kratschmer. Trata-se de um arco reflexo cuja aferência é originária nas terminações nervosas do nervo trigêmeo. A apresentação clínica do reflexo trigêmino-cardíaco é a ocorrência de súbita bradicardia, hipotensão, apneia e hipermotilidade gástrica. Conclusão: O reflexo trigêmino-cardíaco pode ser uma resposta neurogênica protetora, oxigênio-conservadora, de baixa morbidade, contudo exacerbada em determinadas situações. A interação entre cirurgião e anestesiologista, aliada à monitoração criteriosa da pressão arterial e do ritmo cardíaco, é fundamental para o diagnóstico e o tratamento.

Abstract Background: Trigeminocardiac reflex is a physiological phenomenon that may occur in head and neck surgery, and is usually benign. However, it may present with exaggerated responses with severe morbidity. Case report: Male patient, 26 years old, candidate for surgical treatment of zygomatic-orbital complex fracture. The surgery with bilateral nasal packing placed at the end of the procedure was uneventful. After being admitted to the post-anesthesia care unity, the patient complained of shortness of breath and nausea. Pulse oximetry fell below 90% in ambient air, and 100% O2 was then offered through a Hudson mask. He showed no improvement in oximetry and presented with worsening dyspnea, diffuse wheezing, reduced heart rate, and blood pressure. Atropine was given, which raised the heart rate, but without resolution of hypotension and bronchospasm. Our suspicion was of a trigeminal-cardiac reflex, and then the removal of the nasal packing was done with complete remission of the signs and symptoms. Discussion: Florian Kratschmer (1870) was the first to describe the influences of nasal mucosal reflexes on respiration and circulation, which became known as Kratschmer's reflex. It is a reflex arc whose afferent originates in the nerve endings of the trigeminal nerve. The clinical presentation of trigeminocardiac reflex is the occurrence of sudden bradycardia, hypotension, apnea, and gastric hypermotility. Conclusion: Trigeminocardiac reflex may be a protective neurogenic, oxygen-conserving response with low morbidity, however, exacerbated in certain situations. The interaction between surgeon and anesthesiologist, together with a careful monitoring of blood pressure and heart rate are fundamental for diagnosis and treatment.

RESUMO Introdução: Os atletas arremessadores sofrem adaptações na amplitude de movimento (ADM) do ombro, como amplitude excessiva, ganho de rotação lateral (RL) e restrição de rotação medial (RM) devido à prática esportiva. Uma assimetria maior que 20° pode tornar o atleta mais suscetível a lesões. Existem semelhanças entre os esportes que utilizam arremesso devido à ampla quantidade de movimentos em rotação lateral máxima. Nesses esportes, a restrição de rotação medial (RM), o excesso de rotação lateral (RL) e as dores no ombro são frequentes, principalmente, em atletas que são expostos aos arremessos. Objetivo: Avaliar a ADM de RM e RL do ombro de atletas de diferente modalidades esportivas considerando sua influência nas lesões e no desempenho funcional. Métodos: Avaliou-se a ADM de rotação da articulação glenoumeral em 477 atletas jovens. Os atletas foram categorizados em três grupos de esportes: natação; arremesso e não-arremesso, distribuídos em relação à faixa etária. As Análises de Variância (ANOVA) foram realizadas para verificar diferenças nas RM e RL entre os grupos e o Teste t Student pareado para verificar diferenças entre os lados (assimetria). Resultados: Os atletas mais novos apresentaram média de RL significativamente menor em relação aos mais velhos, em ambos os lados. O presente estudo demonstrou que o lado direito possui menor RM e maior RL em todos os grupos. Conclusão: Os achados desse estudo comprovaram que os grupos de arremesso e natação têm características semelhantes quanto à ADM de rotação do ombro. Nível de evidência III; Estudos diagnósticos – Investigação de um exame para diagnóstico.

ABSTRACT Introduction: Overhead-throwing athletes undergo changes in shoulder range of motion (ROM) due to sports activities, such as excessive amplitude, lateral rotation (LR) increase and medial rotation (MR) restriction. Asymmetry greater than 20° may render athletes more prone to injuries. There are similarities among sports featuring overhead throwing due to the considerable amount of movements involving maximum lateral rotation. In these sports, medial rotation (MR) restriction, excess of lateral rotation (LR) and shoulder pain are common, particularly in overhead-throwing athletes. Objective: To assess shoulder MR and LR ROM in athletes participating in different sports, considering the influence of these variables on injuries and functional performance. Methods: The rotation ROM of the glenohumeral joint was assessed in 477 young athletes, who were categorized in three sports groups: swimming, overhead-throwing and non-overhead throwing, distributed by age group. Analyses of Variance (ANOVA) were performed to verify if there were differences in MR and LR between groups and paired Student t test was used to verify differences between sides (asymmetry). Results: Youngest athletes showed significant shorter LR than the oldest, in both sides. This study demonstrated that the right side has less MR and greater LR in all groups. Conclusion: The findings showed that overhead-throwing and swimming groups have similarities in shoulder rotation ROM. Level of evidence III; Diagnostic Studies - Investigating a Diagnostic Test.

RESUMEN Introducción: Los atletas lanzadores sufren adaptaciones en la amplitud de movimiento (ADM) del hombro, como amplitud excesiva, aumento de rotación lateral (RL) y restricción de rotación medial (RM), debido a la práctica deportiva. Una asimetría mayor que 20° puede hacer que el atleta sea más susceptible a las lesiones. Hay similitudes entre los deportes que utilizan el lanzamiento debido a la gran cantidad de movimientos en rotación lateral máxima. En estos deportes, la restricción de rotación medial (RM), exceso de rotación lateral (RL) y dolores en el hombro son frecuentes, principalmente en atletas que están expuestos a los lanzamientos. Objetivo: Evaluar la ADM de RM y RL del hombro de atletas de diferentes modalidades deportivas teniendo en vista su influencia en las lesiones y en el desempeño funcional. Métodos: Se evaluó la ADM de rotación de la articulación glenohumeral en 477 atletas jóvenes. Los atletas se clasificaron en tres grupos de deportes: natación; lanzadores y no Lanzadores, distribuidos con relación al grupo de edad. Los análisis de varianza (ANOVA) se realizaron para verificar diferencias en las RM y RL entre los grupos y el test t Student pareado para verificar diferencias entre los lados (asimetría). Resultados: Los atletas más jóvenes presentaron un promedio de RL significativamente menor con relación a los más viejos, en ambos lados. Este estudio demostró que el lado derecho posee menor RM y mayor RL en todos los grupos. Conclusión: Los hallazgos de este estudio comprobaron que los grupos de lanzadores y natación tienen características similares cuanto a la ADM de rotación del hombro.

RESUMO O Brasil apresenta uma demanda anual de mais de 2,83 milhões de toneladas de fertilizantes fosfatados. Parte disto se deve a baixa eficiência no uso do fósforo (EUP) pelas plantas, especialmente nos atuais cultivares de milho. Assim, objetivou-se foi elaborar índices que permitam a seleção acurada de genótipos de milho eficientes no uso de P para condições de baixa e alta disponibilidade deste nutriente. O experimento foi conduzido em casa de vegetação (20º45'14"S; 42º52'53"W), na Universidade Federal de Viçosa, em outubro de 2010. Foram avaliadas 39 combinações híbridas experimentais e 14 linhagens de milho, divergentes para a eficiência no uso de P, em duas condições de disponibilidade deste nutriente. Foi realizada a análise de importância relativa dos caracteres estudados, estimada por meio do método dos componentes principais, a análise de fatores e confecção dos índices de seleção. Para obtenção de genótipos responsivos a alta disponibilidade de fósforo é recomendado o índice ISAP = 0,3985 MRS + 0,3099 MPS + 0,5567 CRLAT + 0,2340 EAbP - 0,1139 SER. Para obtenção de genótipos tolerantes a baixa disponibilidade deste nutriente é sugerido o índice ISBP = 0,3548 MRS + 0,3996 CRLAT + 0,3344 MSP + 0,0041 PA/SR - 0,1019 SER.

ABSTRACT Brazil generates an annual demand for more than 2.83 million tons of phosphate fertilizers. Part of this is due to low P use efficiency (PUE) by plants, particularly in current maize cultivars. Thus, the aim of this study was to create indexes that allow accurate selection of maize genotypes with high PUE under conditions of either low or high P availability. The experiment was conducted in a greenhouse (20º45'14"S; 42º52'53"W) at the Universidade Federal de Viçosa in October 2010. We evaluated 39 experimental hybrid combinations and 14 maize inbred lines with divergent PUE under two conditions of P availability. The relative importance of the traits studied was analyzed and estimated by principal component analysis, factor analysis, and establishment of selection indexes. To obtain genotypes responsive to high P availability, the index SIHP (selection index for high phosphorus) = 0.3985 RDM + 0.3099 SDM + 0.5567 RLLAT + 0.2340 PUEb - 0.1139 SRS is recommended. To obtain genotypes tolerant to low P availability, the index SILP (selection index for low phosphorus) = 0.3548 RDM + 0.3996 RLLAT + 0.3344 SDM + 0.0041 SH/RS - 0.1019 SRS is suggested.

RESUMOO objetivo deste estudo foi avaliar o desenvolvimento motor de uma criança com Síndrome de Williams e verificar os efeitos de um programa de intervenção motora. Trata-se de uma pesquisa descritiva do tipo estudo de caso. Para a avaliação do desenvolvimento motor foram utilizados os testes da Escala de Desenvolvimento Motor - EDM. Essa criança participou de avaliação motora, intervenção motora (32 sessões, duas vezes semanais) e reavaliação motora. As intervenções motoras mostraram avanços positivos nas áreas da motricidade fina, equilíbrio e organização espacial. Verificou-se que o esquema corporal e a organização temporal foram as áreas de maior prejuízo. O quociente motor geral foi classificado como muito inferior o que caracteriza déficit motor. Esses dados justificam a relevância de programas de intervenção motora para essa população.

ABSTRACTThe objective of this study was to evaluate the motor development of a child with Williams syndrome and to verify the effect of a motor intervention program. This is a descriptive case study. Motor development was evaluated using the Motor Development Scale - MDS. The child's motor assessment, motor intervention (32 sessions, twice weekly) and motor reevaluation were carried out. Gains were demonstrated in motor intervention in the areas of fine motor skills, balance and spatial organization. Body Schema and temporal organization were found to be the areas of lesser achievement. The motor quotient generally for all items was classified as very low, characterizing motor deficit. The data justifies the relevance of motor intervention programs for children with Williams syndrome.

RESUMO Objetivo: identificar as vantagens e desvantagens associadas ao uso do método design-build de contratação, com vistas a uma possível adoção pelo setor público brasileiro. Método: estudo de caso de natureza qualitativa, no qual foram realizadas pesquisas documentais e de campo, na forma de entrevistas semiestruturadas. Sobre os dados documentais e de campo foi aplicada análise de conteúdo, bem como triangulação de métodos de coleta e fontes. Fundamentação teórica: a fundamentação teórica desta pesquisa reside na legislação brasileira para contratação de obras e estudos realizados por diversos autores nos quais abordam as vantagens do método de contratação design-build (uma única contratação para projeto e construção) em relação ao design-bid-build, método utilizado no Brasil, que contrata projeto e construção separadamente. Resultados: foram identificados vantagens, desvantagens e riscos prováveis associados à adoção do design-build, possibilitando a formulação de estratégias de enfrentamento caso venha a ser implantado. Contribuições: gestores cientes das vantagens, desvantagens e riscos associados ao design-build podem conceber estratégias de enfrentamento adotando medidas que eliminem ou minimizem seus efeitos. Os resultados podem contribuir não apenas para uma possível implantação do método em contextos inclusive distintos do público, como também para a melhoria dos processos concernentes a projeto e execução de obras.

ABSTRACT Objetivo: This paper aims to identify advantages, disadvantages and risks involved in the adoption of design-build contracting method in the Brazilian public sector. Design/methodology/approach: qualitative case study, in which were made documentary and field research in the form of semi-structured interviews. About the documentary and field data was used content analysis and triangulation of sources and collection methods. Findings: The theoretical basis of this research lies in the brazilian legislation for contracting works and studies conducted by various authors in which address the advantages of design-build procurement method (a single contract for design and construction) regarding the design-bid-build method used in Brazil, which hires design and construction separately. Practical implications: The research identified advantages, disadvantages and risks associated to the adoption of the design-build method , enabling the development of coping strategies if it is deployed. Originality/value: managers aware of these aspects could use coping strategies by adopting measures to reduce or eliminate their effects. The results can contribute not only to a possible implantation of the method in contexts even other than the public sector but also to improve the processes regarding the project and execution of works.

O melhoramento genético das eficiências no uso de N (EUN) e P (EUP) é um dos meios para se obterem produtividades de grãos satisfatórias, com menores custos e de modo sustentável. Todavia, pouco se sabe a respeito da relação entre os caracteres determinantes dessas eficiências, o que tem dificultado o uso da seleção precoce e indireta. Portanto, objetivou-se, com este trabalho, identificar a relação entre os caracteres determinantes das eficiências no uso de nitrogênio e fósforo, em milho. Para isso, avaliaram-se 14 linhagens e 39 híbridos simples, em dois experimentos, em baixa e alta disponibilidade de N e P, em delineamento inteiramente ao acaso, com duas repetições, em esquema fatorial simples. Os experimentos foram conduzidos em telado. Foram utilizados tubos cilíndricos de PVC, com 4 dm³ de capacidade, preenchidos com dois tipos de substrato, de acordo com o experimento. As soluções nutritivas foram fornecidas a partir do sétimo dia após o transplantio, aplicando-se 250 ml tubo-1, a cada dois dias. As plantas foram colhidas em estádio de seis folhas completamente expandidas (V6) e os caracteres avaliados foram: massa da parte aérea seca (MPS), área de raiz específica (ARE), comprimento de raízes laterais (CRLat) e axiais (CRAxi) e os dois componentes da EUN e EUP, as eficiências de utilização (EUt) e a de absorção (EAb). Foram realizadas análises de variância e de trilha dos dados coletados. Os caracteres de raiz não apresentaram efeitos significativos sobre as EUN e EUP. A MPS é o principal determinante das EUN e EUP, independentemente da disponibilidade nutricional.

The genetic improvement of N (EUN) and P (EUP) use efficiency is a less expensive and more sustainable way to obtain satisfactory grain yields. However, the lack of knowledge about the relationship among the determinant characters of nutrient use efficiency has made the use of early and indirect selection difficult. Therefore, the objective of this study was to identify the relationship among the determinant characters of nitrogen and phosphorus use efficiency in maize. In this study, 14 lines and 39 single-cross hybrids were tested in two experiments with low and high N and P availability, in a completely randomized simple factorial design with two replications. The experiments were conducted in a shade house. Were used PVC cylindrical tubes with 4 dm³ capacity filled with two types of substrate, according to the experiment. The nutrient solutions were provided from the seventh day after transplanting, applying 250 ml tube-1 every two days. Plants were harvested at the stage of six fully expanded leaves (V6) to evaluate the traits: shoot dry mass, specific root area, lateral and axial root length and the two components of EUN and EUP, i.e., the utilization (EUt) and uptake efficiency (EAb). According to the analyses of variance and path analysis of the collected data, EUN and EUP were not significantly influenced by the root traits. The main determinant character of EUN and EUP is shoot dry mass, regardless of the nutrient availability.
