13. Ambulatory blood pressure monitoring parameters in hypertensive patients with and without chronic kidney disease / Comparação de parâmetros da monitorização ambulatorial da pressão arterial em pacientes hipertensos com e sem doença renal crônica
Systemic arterial hypertension (SAH) and chronic kidney disease (CKD) are two indissoluble clinical conditions; SAH is cause and consequence of CKD. Adequate blood pressure (BP) control can slow the progression of renal damage and diminish cardiovascular complications. Ambulatory Blood Pressure Monitoring (ABPM) has better accuracy than office blood pressure

14. Microestrutura e deformação a quente de um aço dinx20cr13 na laminação de tubos sem costura
The DIN X20Cr13 stainless steel is a high technological alloy usually used in oil industry for onshore and offshore tubing applications. In this study DIN X20Cr13 equilibrium diagrams were made by Thermo-Calc software to study transformation reactions in solid state phases. This stainless steel was submitted to different heat treatments in order to generate

15. Utilization of fluorescent probe association for simultaneous assessment of plasmatic, acrosomal, and mitochondrial membranes of rooster spermatozoa
This experiment was designed with the objective of developing a simple, practical, and high repeatability technique for the simultaneous evaluation of the integrity of the plasmatic and acrosomal membranes, as well as funcional mitochondria of domestic fowl spermatozoa using an association of fluorescent probes. Four ejaculates (motility > 80% and abnormal m

16. AvaliaÃÃo do dano provocado por Bipolaris maydis em Panicum maximum cv. TanzÃnia-1 / Assessment of the damage caused by Bipolaris maydis in Panicum maximum cv. TanzÃnia-1
A mancha foliar causada por Bipolaris maydis representa uma das principais doenÃas da gramÃnea forrageira Panicum maximum cv. TanzÃnia-1 (capim TanzÃnia), no entanto, nÃo hà informaÃÃes sobre o dano gerado por esta doenÃa. O objetivo deste trabalho foi avaliar o dano causado por B. maydis na quantidade e qualidade da produÃÃo do capim TanzÃnia-1.

17. On a continuum theory of brittle materials with microstructure
This paper deals with a finite strain continuum theory of elastic-brittle solids with microstructure. A single scalar microstructural field is introduced, meant to represent - even if in a summary way - the concentration of microdefects within the material. A system of microforces, dual to the microstructural field, is axiomatically introduced. The correspon

18. Modelagem matematica e simulação numerica do refriamento rapido com ar forçado de morango
The temperature is one of the main factors that affects the fruits life after harvest. Increasing the temperature, speeds up the metabolism of the fruits, taking them to faster deterioration. One of the best ways to prevent the fruits of this kind of damage, is to apply the pre-cooling immediately after harvest, and to control the temperature during its st

19. Estudos de Bacillus thuringiensis Berliner visando ao controle de Spodoptera frugiperda (J.E.Smith). / Bacillus thuringiensis berliner research applied for the control of Spodoptera frugiperda (J. E. Smith).
From 24 soil samples about 461 bacterial colonies have been isolated, and 190 were identified as Bacillus thuringiensis (Bt). The relation between soil chemical characteristics and the presence of this pathogen may be expressed by the equation iBt = -0,4 + 0,6Ca + 0,07Cu + 0,009Fe - 0,53Mg -0,12Mn + 1,26Zn. Among 83 Bt isolates assayed against Spodoptera fru

20. Damage theory: microscopic effects of vanishing macroscopic motions
This paper deals with a mechanical model describing the evolution of damage in elastic and viscoelastic materials. The state variables are macroscopic deformations and a microscopic phase parameter, which is related to the quantity of damaged material. The equilibrium equations are recovered by refining the principle of virtual powers including also microsco

21. Desenvolvimento de ferramentas computacionais para analise estrutural em fadiga e geração de malhas de elementos finitos
This work deals with the structural analisys of problems involving mechanical fatigue using the Finite Element Method and Software Engineering concepts. Initially, the basic concepts of mechanical fatigue, the conventional design techniques and the major research areas are reviewed. The material constitutive model to treat the fatigue process is developed ba

22. Analise transiente de pressão do fluxo linear multifaxco
The transient flow of fluids in linear homogeneous solution gas-drive reservoirs is studied in this work. Gravity andcapillary effects are assumed negligible. Wellbore storage and damage are not considered and water phase is assumed to be incompressible and immobile. In particular, theoretical support is provided for Well Test Analysis of hydraulic verticall

23. Reduction of nitrite to nitric oxide during ischemia protects against myocardial ischemia–reperfusion damage
Nitric oxide (NO•) is thought to protect against the damaging effects of myocardial ischemia–reperfusion injury, whereas xanthine oxidoreductase (XOR) normally causes damage through the generation of reactive oxygen species. In the heart, inorganic nitrite \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \us
