1. Productive traits of rye cultivars grown under different sowing seasons
RESUMO Objetivou-se neste estudo ajustar os modelos não lineares Gompertz e Logístico, para as massas de matéria fresca e seca de parte aérea e indicar o modelo que melhor descreve o crescimento de duas cultivares de centeio em cinco épocas de semeadura e caracterizar o crescimento das cultivares em relação às massas de matéria fresca e seca de part

2. Morphological sexual maturity of the freshwater anomuran crab Aegla parana (Crustacea, Decapoda, Aeglidae) from Negro River Sub-basin, Upper Iguaçu Basin, southern Brazil
RESUMO O comprimento da carapaça (CL) no início da maturidade sexual morfológica (MSM) em Aegla paranaSchmitt, 1942foi estimado em uma população que ocorre na Sub-bacia do Rio Negro, Bacia do Alto Iguaçu, sul do Brasil. Os animais foram capturados com rede Surber e com armadilhas iscadas no Rio Negro e no seu afluente Rio Totó, em dezembro/2017, junho

3. Uma nova abordagem para a medição da diluição de soldagem, baseada nos pontos de inflexão de um Contorno Ativo
RESUMO Em diversas aplicações, com ênfase nos processos de soldagem dissimilar, a diluição, em conjunto com outros fatores, pode afetar as propriedades mecânicas dos materiais soldados, sendo assim, capaz de gerar falhas durante as condições normais de serviço. Deste modo, a taxa de diluição geralmente é calculada a partir da análise de imagens

5. Inflection and stability points of diphasic logistic analysis of growth
Growth functions with inflection points following a diphasic model, can be adjusted by two approaches using segmented regression or the sum of two functions. In both cases, there are two functions, one for each phase, with inflection and stability points. However, when they are summed, the result is a new function and the points of inflection and stability a

6. Caracterização da curva de crescimento de fêmeas Crioulas Lageanas criadas em condições naturais
Morphometry and ultrasound of carcasses were used to estimate the growth curve of Criola Lageana cows, raised under natural conditions. A total of 111 cows, raised under extensively production system in Central Plateau of Santa Catarina, were evaluated. Morphometrics and ultrasound measurements were related with the age of the animals using the targeted univ

7. Modelagem computacional do efeito bystander das radiações ionizantes via autômato celular e técnica Monte Carlo
Until the 1990s it was believed that the DNA was the only target molecule of ionizing radiation. But some observations have questioned this theory. In 1992, the bystander effect was described by Nagasawa and Little. This effect is responsible for a series of answers as death, chromosomal instability or other abnormalities that occur in non-irradiated cells,

8. Critical points in logistic growth curves and treatment comparisons
Several biological phenomena have a behavior over time mathematically characterized by a strong increasing function in the early stages of development, then by a less pronounced growth, sometimes showing stability. The separation between these phases is very important to the researcher, since the maintenance of a less productive phase results in uneconomical

9. Morfodinâmica associada entre duna, praia e zona submarina como subsídio a adequada ocupação do espaço costeiro na Praia do Peró - RJ. / Morphodynamics associated between dune, beach and underwater area as an aid to proper occupation of coastal space in Praia do Pero - RJ.
The coastline offers a veritable mosaic of diversity in coastal landforms, which enable the development of a number of different economic activities. Coastal environments are highly dynamic and involve a complex series of continental and oceanic processes. The beach of Pero, located between Cape Buzios and Cabo Frio, Rio coast, appears as an area distinct fr

10. A sigmoidal fit for pressure-volume curves of idiopathic pulmonary fibrosis patients on mechanical ventilation: clinical implications
OBJECTIVE: Respiratory pressure-volume curves fitted to exponential equations have been used to assess disease severity and prognosis in spontaneously breathing patients with idiopathic pulmonary fibrosis. Sigmoidal equations have been used to fit pressure-volume curves for mechanically ventilated patients but not for idiopathic pulmonary fibrosis patients.

11. A scanographic assessment of alveolar recruitment and overinflation during high frequence ventilation : preliminary results in three patients
BACKGROUND AND OBJECTIVES: High-frequency ventilation (HFV) may offer an attractive alternative to conventional strategies in the ventilation of the acute respiratory distress syndrome (ARDS) or acute lung injury (ALI) because it can minimize lung injury. Maintaining ventilation between lower and upper inflection points, it can warrant alveolar recruitment w

12. Batalhas da memória política em Sergipe : as comemorações das mortes de Fausto Cardoso e Olímpio Campos (1906-2006)
This dissertation analyzes the memory conflicts that are present in the commemorations of the deaths of Fausto Cardoso and Olímpio Campos, in the period between 1906 and 2006. The antagonistic group political leaders, Fausto Cardoso and Olímpio Campos, were assassinated following a rebellion that occurred in Sergipe in 1906. Since then, faustistas and olim
