1. PERFORMANCE AND WELFARE OF FINISHING PIGS SUBJECTED TO CLIMATECONTROLLED ENVIRONMENTS AND SUPPLEMENTARY LIGHTING
ABSTRACT An adequate thermal environment in pig farming facilities is essential to ensure productivity and animal welfare. The objective of this study was to evaluate the behavior and performance of finishing pigs, subjected to climate-controlled environments and supplementary lighting. Twenty-seven pigs (3/4 Duroc, 1/4 Pietrain) were kept in pens with no cl

2. Acondicionamiento del gas inhalado en pacientes con vía aérea artificial. Revisión narrativa
ABSTRACT Instrumentation of the airways in critical patients (endotracheal tube or tracheostomy cannula) prevents them from performing their function of humidify and heating the inhaled gas. In addition, the administration of cold and dry medical gases and the high flows that patients experience during invasive and non-invasive mechanical ventilation generat

3. EVATUATION SYSTEM OF EXHAUST FANS USED ON VENTILATION SYSTEM IN COMMERCIAL BROILER HOUSE
ABSTRACT: This study aim to develop a system, called FANS-N, for evaluation the exhaust fans in the ventilation system of broiler facilities. The system is divided into: 1) Mechanical Structure - consisting of two stepper motors for positioning a anemometer sensor in the vertical and horizontal coordinates; 2) Electronic Interface - control of the anemometer

4. PESTICIDES DEPOSITION IN VINEYARDS ON DIFFERENT CONDITIONS OF LEAF WETNESS
ABSTRACT The high susceptibility to diseases of fine table grapes cultivars demand intensive use of pesticides, and the presence of water on the leaf surface can worsen the deposition of these products. The objective of this study was to evaluate the spray deposition in vine leaves in different conditions of leaf wetness, and test the effectiveness of an art

5. Parameter estimation of an artificial respiratory system under mechanical ventilation following a noisy regime
Abstract Introduction: This work concerns the assessment of a novel system for mechanical ventilation and a parameter estimation method in a bench test. The tested system was based on a commercial mechanical ventilator and a personal computer. A computational routine was developed do drive the mechanical ventilator and a parameter estimation method was util

6. Estudo do funcionamento da ventilação assistida proporcional plus em um sistema pulmonar mecânico / Study of the functioning of the proportional assist ventilation plus in a mechanical lung model
INTRODUÇÃO: Ventilação assistida proporcional plus é um novo conceito de suporte ventilatório assistido que visa atuar de acordo com os níveis de esforço inspiratório, mecânica respiratória e níveis de porcentagem de apoio. A complexa interação entre esses fatores que comandam a sua função é de difícil interpretação na prática clínica.

7. Efeitos fisiológicos da ventilação de alta frequência usando ventilador convencional em um modelo experimental de insuficiência respiratória grave / Physiological effects of high frequency ventilation with conventional ventilator in an experimental model of severe respiratory failure
Introduction: Acute respiratory distress syndrome (ARDS) has a high incidence and mortality between critical ill patients. The mechanical ventilation is the most important support for these patients with ARDS. However, until now there is an important debate about how is the best ventilatory strategy to use, because the mechanical ventilation if not well set

8. Evaluation of reflective painting of the roof and artificial ventilation on performance and carcass yield of broilers
This study was developed with the objective of evaluating reflective paint on covering and artificial ventilation on performance of broilers (males and females). A randomized design with a 2 × 2 × 2 factorial arrangement of treatments was used, as follows: 2 external management systems (coverage with and without reflective paint), 2 internal management sys

9. Análise da cinemática dos compartimentos da parede torácica nas posições supino e sentada de pacientes com esclerose lateral amiotrófica
Amyotrophic Lateral Sclerosis (ALS) is characterized by deterioration of upper and lower motor neurons. The main components, which alter the respiratory muscles are the inspiratory, expiratory, and bulbar, leading to chronic respiratory failure. One way to improve gas exchange of these individuals is by employing non-invasive ventilation (NIV). Therefore, th

10. Ventilação mecânica não invasiva com pressão positiva em vias aéreas, em pacientes HIV/AIDS com lesão pulmonar aguda e insuficiência respiratória: estudo de avaliação do melhor valor de PEEP / Noninvasive ventilation with positive airway pressure in HIV/AIDS patients with acute lung injury and respiratory failure: study to assess the best level of PEEP
INTRODUÇÃO: A síndrome da imunodeficiência adquirida (AIDS) é atualmente uma pandemia, e as doenças pulmonares são a principal causa de morbidade e mortalidade dos pacientes com AIDS. Nesse sentido, as infecções respiratórias são frequente causa de hipoxemia e morte. Os pacientes com AIDS e insuficiência respiratória hipoxêmica frequentemente n

11. Avaliação dos efeitos de protocolos de manuseio mínimo em parâmetros fisiológicos de recém-nascidos pré-termo com doença de membrana hialina em ventilação mecânica
The literature recommends the practice of minimal handling during the first 72 hours of life to preterm newborn due to the risk of periventricular and intraventricular hemorrhage (PIVH) in the first days of life. However, there are few published studies that evaluate the effects of the use of minimal handling protocol in the group of preterm infants and the

12. Influência da estratégia ventilatória no desempenho funcional de enxertos pulmonares em um modelo experimental de transplante pulmonar unilateral de doadores após parada cardiocirculatória / Ventilation strategy and its influence on the functional performance of lung grafts in an experimental model of single lung transplantation using non-heart-beating donors
Objetivo: Comparar a influência de duas estratégias ventilatórias — ventilação controlada a volume (VCV) e ventilação controlada a pressão (VCP) — no desempenho funcional de enxertos pulmonares em um modelo canino de transplante pulmonar unilateral esquerdo, utilizando-se doadores cujos pulmões foram captados após três horas de parada cardioci
