1. Desestratificação de reservatórios por meio de aeração artificial
RESUMO No presente trabalho, avaliou-se em escala de laboratório e por meio de modelagem matemática o processo de desestratificação da coluna d’água usando aeração por ar difuso. Foram identificados dois padrões de escoamento: um regime de pluma, no qual o escoamento induzido pelas bolhas penetra na interface entre as duas camadas de diferentes den

2. PRODUCTIVE RESPONSES FROM BROILER CHICKENS RAISED IN DIFFERENT COMMERCIAL PRODUCTION SYSTEM - PART II: IMPACT OF CLIMATE CHANGE
ABSTRACT Broiler chickens are homoeothermic animals, i.e., animals capable of maintaining their body temperature within quite narrow limits; therefore, climate change poses a great challenge to poultry. With this in mind, this research aims to evaluate the performance of broilers submitted to different commercial production systems and exposed to different f

3. Physiological responses of growing pigs to high ambient temperature and/or inflammatory challenges
ABSTRACT Global warming is one of the major environmental threats facing the world in the 21st century. This fact will have a significant impact on pig production due to its direct effects on welfare, health, and performance of pigs. Besides, the effects of high temperatures will presumably become more important over the next decades due to the development o

4. PYROLIGNEOUS LIQUOR PRODUCED FROM ACACIA MEARNSII DE WILD WOOD UNDER CONTROLLED CONDITIONS AS A RENEWABLE SOURCE OF CHEMICALS
Acacia mearnsii de Wild (black wattle) is one of the most important trees planted in Southern Brazil for tannin extraction and charcoal production. The pyrolysis of the black wattle wood used for obtaining charcoal is performed in brick ovens, with the gas fraction being sent directly into the environment. The present study examines the condensable compounds

5. CONTEXT MANAGEMENT: TOWARD ASSESSING QUALITY OF CONTEXT PARAMETERS IN A UBIQUITOUS AMBIENT ASSISTED LIVING ENVIRONMENT
This paper provides an approach to assessing Quality of Context (QoC) parameters in a ubiquitous Ambient Assisted Living (AAL) environment. Initially, the study presents a literature review on QoC, generating taxonomy. Then it introduces the context management architecture used. The proposal is verified with the Siafu simulator in an AAL scenario where the u

6. Microstructure and mechanical properties of two Api steels for iron ore pipelines
This research compares the mechanical behavior of two API steels (X60 and X70) used in the longest pipeline in the world for the conveyance of iron ore. Tensile tests, Charpy impact tests, CTOD tests and fatigue crack growth tests are performed at ambient temperature. Metallographic examination showed a banded microstructure consisting of polygonal ferrite a

7. Assessment of microbiological air quality in hemato-oncology units and its relationship with the occurrence of invasive fungal infections: an integrative review
Worldwide aging of the human population has promoted an increase in the incidence of neoplasia, including hematological cancers, which render patients particularly vulnerable to invasive fungal infections. For this reason, air filtration in hemato-oncology units has been recommended. However, scarce literature has assessed the impact of microbiological air q

8. Lean diesel technology and human health: a case study in six Brazilian metropolitan regions
OBJECTIVE: Due to their toxicity, diesel emissions have been submitted to progressively more restrictive regulations in developed countries. However, in Brazil, the implementation of the Cleaner Diesel Technologies policy (Euro IV standards for vehicles produced in 2009 and low-sulfur diesel with 50 ppm of sulfur) was postponed until 2012 without a comprehen

9. Acceptability of goat meat in food habits and perceptions about the environmental impact the production of goats in the in the northeast between students / Aceitabilidade da carne caprina no hábito alimentar e percepção sobre o impacto ambiental na produção de caprinos no nordeste entre estudantes universitários
The present work has an objective of investigate the acceptability of consumption of the goat meat and studies the perception of university students on the productive sector of goats in the Northeast. The habit to eat goat meat has strong regional traditions and has been suffering the demographic, cultural, economic and personal influences. Currently, a new

10. Human risk assessment for air pollution by passive biomonitoring: a case study in São Mateus do Sul, Paraná, Brazil / Avaliação do risco humano a poluentes atmosféricos por meio de biomonitoramento passivo: um estudo de caso em São Mateus do Sul, Paraná
In developing countries significant sources of air pollution may go undetected in areas that do not have qualified structure to measure air contaminants. In this context, simplified methods of measuring ambient particles, such as portable impactors and trace elements accumulate in tree barks, may provide information to identify areas influenced by source emi

11. Analysis on the limitation of the law in the solution of environmental conflicts: the use of geographic information systems in judicial proceedings / Análise das limitações do direito na solução de conflitos ambientais: a aplicação de sistemas de informações geográficas a processos judiciais
There is a hiatus between the environmental law existence, mainly because of its great rigidity, and the fact of being considered an impediment to the economic development. The Permanent Preservation Areas (PPA) and Legal Forest Reserve (LFR) are institutes created by the Environmental Law that limit the economic exploitation in rural properties without an i

12. Characterization and estimation of occurrence of heat waves with impact on broiler mortality / Caracterização e previsão de ondas de calor com impacto na mortalidade de frangos de corte
As broiler production increases in Brazil it appears the need of optimizing production system mainly due to the market competitiveness, and technological resources application are required for reducing losses. Productive loss decurrently from heat wave (HW) incidence is quite common in broiler rearing under tropical conditions, and the solution for this is a
