13. Biologia da polinização, reprodução e genética de duas populações de Tibouchina pulchra Cogn. (Melastomataceae) em gradiente altitudinal no sudeste do Brasil / Pollination, reproductive biology and genetic of two populations of Tibouchina pulchra Cogn. (Melastomataceae) at altitudinal gradient in southeastern Brazil
As montanhas apresentam alta diversidade e diferentes condições ambientais ao longo de curtas distâncias. Assim, as montanhas são ideais para estudos ecológicos e evolutivos que podem somar valores e aprimorar projetos de conservação. Em altitudes elevadas as condições ambientais podem reduzir a quantidade de polinizadores, principalmente de abelhas

14. ANÃLISE TÃCNICO-ECONÃMICA DA RECUPERAÃÃO DE UM SOLO SÃDICO NO PERÃMETRO IRRIGADO CURU-PENTECOSTE-CE / Techno-economical analysis of the reclamation of a sodic soil in the Irrigated Perimeter Curu-Pentecoste-CE.
In the semi-arid part of Northeastern Brazil, the highest incidences of salinized areas are observed in land subjected to intense irrigated cultivation, in the âPerÃmetros Irrigadosâ (irrigated perimeters), particularly those where is used the surface method. The experiment was performed in the âNÃcleo Dâ (D Core) of the âPerÃmetro Irrigado Curu-Pent

15. Modelling the steady state and dynamic conditions of a biotrickling filter treating styrene and acetone in air
The aim of this work was the study a trickling biofilter, where water was circulated throughout the bed. In the first steady state experiment, the packing materials used were 25mm Pall rings. The airflow rate was increased gradually and the concentration of styrene in the air stream was held constant. In the second experiment, 15mm Pall rings were used. In t

17. A contribution to the study on cold forging of steel helical gears / Uma contribuição ao estudo do forjamento a frio de engrenagens helicoidais
The forging processes are classified in hot forging, warm forging, and cold forging, that usually provide products that need some further machining operations to achieve manufactured part specifications. Cold forging asks for a special attention when manufacturing complex geometry parts, because its limitation with the forgeability of the workpiece material,

18. Effects of pressure controlled ventilation and volume controlled ventilation on pulmonary function in cardiac surgery patients with cardiopulmonary bypass / Efeitos do suporte ventilatorio com pressão controlada e volume controlado na função pulmonar dos pacientes submetidos a cirurgia cardiaca com circulação extra-corporea
Postoperative lung injury after cardiac surgery with cardiopulmonary bypass (CPB) is usually related to the systemic inflammatory response syndrome (SIRS). Many patients undergoing this procedure develop acute lung injury (ALI), and some of them acute respiratory distress syndrome (ARDS). Many factors can be directly or indirectly related to the postoperativ

19. Distribuição e disponibilidade de recursos florais e estratégias de forrageamento na interação entre beija-flores e Palicourea rígida (Rubiaceae)
Some pollination mechanisms represent mutualistics interactions, in which the plants offer nectar and pollen and the pollinators carry the pollen grains. The hummingbirds are the more specialized pollinators among the birds, and their high energetic cost to fly, force them to develop feeding strategies to obtain the highest energetic gains with the lowest co

21. Avaliação do sistema informático perinatal (SIP CLAP OPS) no monitoramento da assistência hospitalar perinatal em Minas Gerais
Objective: To assess the quality of information and some perinatal indicators of the Perinatal Information System of the Latin-American Center of Perinatology (SIP-CLAP) of the Pan American Health Organization, and their use to monitor perinatal hospital care in Minas Gerais. The research was carried out in three stages: 1) analysis of the quality of the SIP

22. Efeito imediato da pressão positiva continua nas vias aereas não invasiva no volume pulmonar expiratorio final de pacientes com doença pulmonar obstrutiva cronica / Immediate effects of non invasive continuous positive airway pressure in end-expiratory lung volume in chronic obstructive pulmonary disease patients
Bachground: Flow limitation and dynamic hyperinflation are common findings in COPD patients. Inspiratory capacity (IC) has been proposed as a simple method to assess changes in end-expiratory lung volume (EEL V) and lung hyperinflation. However, few studies verified if the application of continuous positive airway pressure (CP AP) could decrease lung hyperin

23. Estudo experimental e de simulação da fluidodinâmica de um leito de jorro com tubo Draft
The spouted bed has been used in several processes as drying, granulation, catalytic polymerization, residues treatment and materials coating. This application is due to the excellent fluid-particle contact and to the characteristics of the solids circulation. In spite of its extensive application, the spouted bed has some scale-up limitations, so its necess
