13. Mapping Three-dimensional Moisture Content of Wood Chip Piles for Energy Production
ABSTRACT The aim of this study was to apply geostatistics to predict the spatial pattern of variations in moisture content of eucalyptus wood chip piles to generate subsidies for adequate sampling and material handling. Wood chip piles were installed in three different storage cycles using newly cut material for 7, 30, and 60 days. Sampling was performed in

14. Effect of Aerodynamic Configuration Parameters on Lateral-Directional Stability of Double-Swept Flying Wing Aircraft
ABSTRACT: Poor lateral-directional stability due to the absence of vertical stabilizer is a great risk to the aircraft with flying wing layout. In this paper, an unmanned aerial vehicle with this kind of configuration is chosen as the research object. A three-dimensional model of the unmanned aerial vehicle is established, and then the sensitivity analysis i

18. The Use of Two-Dimensional Strain Measured by Speckle Tracking in the Identification of Incipient Ventricular Dysfunction in HIV-Infected Patients on Antiretroviral Therapy, Untreated HIV Patients and Healthy Controls
Resumo Fundamento: A maior parte das alterações cardiovasculares dos pacientes infectados pelo vírus da imunodeficiência humana (HIV) tem sido associada ao dano miocárdico causado diretamente pelo vírus. Alguns casos, porém, podem estar associados a efeitos adversos da terapia antirretroviral (TARV). Novas técnicas de avaliação da função ventric

19. 3-Dimensional Echocardiography and 2-D Strain Analysis of Left Ventricular, Left Atrial and Right Ventricular Function in Healthy Brazilian Volunteers
Resumo Fundamentos: Novas técnicas ecocardiográficas são utilizadas no diagnóstico e prognóstico de diversas cardiopatias. No entanto, muitos desses novos índices ainda carecem de valores de referência em diferentes populações. Estudamos esses novos parâmetros ecocardiográficos em um grupo de brasileiros sem doença cardiovascular conhecida. Obj

20. Numerical Study on Response Characteristics of Solid Rocket Pintle Motor
ABSTRACT: Pintle technology is currently a versatile technology used in a solid rocket motor (SRM) to control the desired thrust by changing the nozzle throat area, while effectively controlling the chamber pressure at the same time. The sudden movement of the pintle can induce rapid changes in the flow field and the occurrence of pressure oscillations insid

22. Morphology of the megaspore Lagenoisporites magnus (Chi and Hills 1976) Candilier et al. (1982), from the Carboniferous (lower Mississippian: mid-upper Tournaisian) of Bolivia
Abstract: The morphology and structure of megaspores assigned to Lagenoisporites magnus from the Toregua Formation, Retama Group, mid-upper Tournaisian of Bolivia were studied. The analysis was performed with light, fluorescence and scanning electron microscopy. Megaspores were laterally compressed and presented a spherical body with a proximal gula, of the

23. GRAPHICAL REPRESENTATION ANALYSIS OF COMPLEMENTARY CIVIL PROJECTS USING "CAD 2D", "BIM" AND "RA" AND IDENTIFICATION OF INTERFERENCES
Abstract Technical graphic representation presents problems concerning the reduction of dimensionality from 3D to 2D. AEC (architecture, engineering and construction) projects usually adopt the top view paradigm with two-dimensional orthogonal projection. Recently, three major changes in technical representation were the alteration of orthogonal projection i

24. Applicability of the Electro-Vectorcardiogram in Current Clinical Practice
Resumo O eletrocardiograma (ECG) foi revigorado com o reconhecimento de alterações elétricas que ainda não haviam sido observadas de maneira definitiva. Nesse contexto, principalmente na definição dos substratos arritmogênicos, a associação do ECG com o vetorcardiograma (VCG) propiciou mais informações sobre os fenômenos elétricos cardíacos, po
