Revista Brasileira de Cirurgia Cardiovascular , 1998,
Abstract: Objetivo: Os procedimentos conservadores sobre a valva mitral têm vantagens sobre a troca da mesma. Avaliamos os resultados a médio prazo em pacientes com valvopatia mitral de causa reumática quanto às variáveis clínicas e ecocardiográficas. Casuística e Métodos: Cinqüenta e seis pacientes foram submetidos a procedimentos conservadores sobre a valva mitral de etiologia reumática. Quarenta e seis (82,1%) pacientes eram do sexo feminino e 10 (17,9%) do sexo masculino. A idade média dos pacientes foi de 34,70 anos (desvio padr o 13,88 anos). O tempo médio de seguimento foi de 23,84 meses (desvio padr o 9,23 anos). Vinte e cinco (44,6%) pacientes estavam em classe funcional III ou IV e 11 (19,6%) pacientes apresentavam fibrila o atrial antes da cirurgia. Os procedimentos realizados foram comissurotomia com papilaromiotomia em 11 (19,6%) pacientes, comissurotomia com anuloplastia utilizando órtese maleável de pericárdio bovino em 27 (48,2%) pacientes e anuloplastia com órtese maleável de pericárdio bovino em 18 (32,1%) pacientes. Resultados: Houve um óbito (1,7%) per-operatório (30 dias) no grupo estudado. Um paciente apresentou acidente vascular transitório no período pós-operatório, com total recupera o. Ocorreu melhora quanto ao volume diastólico final do ventrículo esquerdo de 52,0 ± 12,4 mm para 48,8 ± 9,9 (p = 0,001), tamanho do átrio esquerdo de 53,0 ± 8,0 mm para 47,8 ± 7,6 mm (p < 0,0001). Ocorreu melhora significativa quanto à classe funcional (p = 0,0001), ficando apenas 1 (1,8%) paciente em classe III. Ocorreram duas reopera es com 28,5 meses e 2,93 meses de seguimento; ficaram livres de reopera o 96,43% no tempo de seguimento. Conclus o: Concluímos que o reparo da valva mitral a médio prazo proporciona bons resultados, com melhora de parametros ecocardiográficos e clínicos.

Abstract: the objective of this study was to determine the evapotranspiration and yield as well, as the appropriate irrigation scheduling, for mango. the experimental design was in randomized blocks, with four treatments and four repetitions. the irrigation treatments were established based on the reference crop coefficient (kcr), such as: treatment t1 (kcr - 20%), treatment t2 (kcr), treatment t3 (kcr + 20%) and treatment t4 (control). the evapotranspiration of mango was obtained by the soil water balance method and the production components were also evaluated. soil water pressure suction was measured based on twelve sets of mercury tensiometers positioned under the canopy of individual trees. measurements were recorded three times per week at 08:00, 12:00 and 16:00 h. throughout the mango fruiting cycle the mean daily evapotranspirations were 3.0, 3.2, 3.6 and 4.1 mm day-1 in the treatments t1, t2, t3 and t4, respectively. the maximum and minimum yields were 31.1 and 28.1 t ha-1 in the t3 and t4 treatments, respectively. the t3 treatment is more appropriate for the studied area.

Abstract: the objective of this study was to investigate the contribution of the heat storage above the soil heat flux plates and within the canopy upon the components of the energy balance in the mango orchard. the bowen energy-ratio balance method was used for obtaining the energy balance components and evapotranspiration of the mango orchard. the t-student test was applied to evaluate statistical significance of the difference between energy balance component averages under the following conditions: (i) considering and (ii) not considering the heat storage above the fluximeters. the results suggested that: 1) the canopy heat storage is irrelevant compared to the other energy balance components; 2) the above soil heat plates heat storage does not influence the sensible and latent heat fluxes nor the irrigated mango orchard evapotranspiration; 3) the soil heat flux, when corrected for the heat storage above the soil heat plates differs statistically, at the 5% probability level, from that obtained without correction.

Abstract: This article presents the main findings of a case study developed to analyze the relation between the practice of initial literacy of a teacher who taught to the 1 st grade of 1st cycle of Primary School and the learning of the pupils as for the teaching of the System of Alphabetical Writing. The research was carried out in a municipal school of Recife City (Pernambuco State) in which students had high levels of attainment in a national testing. The research involved as methodological procedures an interview with the teacher and the application of one diagnose with the pupils involving activities of writing of words and text. The analysis of the findings pointed out that the practice of the teacher based on “Alfabetizar Letrando” (teaching literacy using a variety of texts and ways of organising the pedagogic practice) helped 87% of the pupils to finish the school year in the alphabetical phase of writing, producing coherent and legible texts.

Estudio prospectivo, longitudinal tratado de cuantificar la variabilidad intra y inter-observador de medición de el altura uterina (AU) y verificar la contribución de un curso capacitación para enfermeras y estudiantes de enfermería en los sesgos de medición. Fueran seleccionados dos participantes que realizaron dos mediciones de cada 20 mujeres embarazadas antes y después del curso. Se calculó la variabilidad intra y inter-observador, el coeficiente de correlación intraclase, el error técnico de medición absoluta y relativa y la fiabilidad de la medida. El teste t de Student mostró reducción estadísticamente significativa (p=0,0396) en el sesgo. Se concluye que la formación de enfermeras y estudiantes de enfermería en la técnica de medición de la AU redujo significativamente la variabilidad intra y inter-observador. A prospective, longitudinal study sought to quantify the intra and inter-observer variability of the uterine height (UH) measurement and verify the contribution of a training course for nurses and nursing students in measurement bias. We selected two participants who performed two measurements in 20 pregnant women before and after the course. We calculated the intra and inter-observer variability, the coefficient of intraclass correlation, the absolute and relative technical error of measurement and the measure reliability. The paired t test showed a statistically significant reduce (p = 0.0396) in the measurement bias. We conclude that the training of nurses and nursing students in the technical measurement of UH significantly reduces intra and inter-observer variability.
