13. Global warming decreases the morphological traits of germination and environmental suitability of Dipteryx alata (Fabaceae) in Brazilian Cerrado
ABSTRACT We experimentally evaluated how different temperatures affect germination of individual seedlings of Dipteryx alata, and estimated the impact of climate change on the species using ecological niche modeling. A total of 240 seeds were randomly distributed among three different temperature treatments (32 ºC, 36 ºC, and 40 ºC), and monitored for 35

14. Climatic Response of Cedrela fissilis Radial Growth in the Ombrophilous Mixed Forest, Paraná, Brazil
ABSTRACT We examined the climatic response of Cedrela fissilis radial growth based on precipitation, air relative humidity, temperature and monthly thermal amplitude. It was intended to assess how the secondary growth of C. fissilis is influenced by the climatic variables and which one are the best growth predictors in Ombrophilous Mixed Forest, southern Bra

16. Effect of observed individual data of performance and excretion on life cycle assessment of piglets
ABSTRACT: The objective was to evaluate the impact of producing piglets fed diets with different crude protein (CP) levels through life cycle assessment and experimental data. In Trial I (performance), 28 crossbred barrow piglets, with an initial average weight of 15.3 ± 1.15 kg were divided into a randomized block design with four treatments, seven replica

17. Avaliação do ciclo de vida do Sistema Municipal de Gerenciamento de Resíduos da Construção Civil da Região Metropolitana de Campinas
RESUMO A ausência ou ineficiência de Sistemas Municipais de Gerenciamento de Resíduos da Construção Civil (SMGRCCs) pode ocasionar impactos ambientais, os quais precisam ser avaliados sistematicamente, levando em consideração a realidade local. Existem poucos estudos sobre a quantificação dos impactos ambientais relacionados ao gerenciamento de res�

18. A CONSTRUÇÃO DO CONHECIMENTO CIENTÍFICO ESCOLAR: HIPÓTESES DE TRANSIÇÃO IDENTIFICADAS A PARTIR DAS IDEIAS DOS(AS) ALUNOS(AS)
RESUMO: A escola vem incorporando discussão cerca das questões socioam-bientais seja devido às orientações curriculares ou abordagens midiáticas. A forma como elas vêm sendo tratadas divergem significativamente, seja do ponto de vista das estratégias utilizadas ou da própria concepção de ciência. No último caso, nota-se certa preocupação em in

19. Anticipating the response of the Brazilian giant earthworm (Rhinodrilus alatus) to climate change: implications for its traditional use
Abstract Our understanding of the impacts of ongoing global warming on terrestrial species has increased significantly during the last several years, but how climatic change has affected, and will affect, the distribution of earthworms remains largely unknown. We used climate niche modeling to model the current distribution of the giant earthworm Rhinodrilus

20. SORÇÃO DE CO2 UTILIZANDO LÍQUIDO IÔNICO ADITIVADO COM EXTENSORES DE ÁREA SUPERFICIAL
The study of environmentally friendly CO2 sorption agents are growing due to the need of mitigate this gas from atmosphere. Ionic Liquids (ILs) present the advantage of having low vapor pressures and being chemically and thermally stable. Besides, their properties can be designed by varying the groups of the cation or anion. Yet, these compounds present a lo

21. Soil CH4 and N2O Emissions from Rice Paddy Fields in Southern Brazil as Affected by Crop Management Levels: a Three-Year Field Study
ABSTRACT Rice yield increases in response to improvements in crop management, but the impact on greenhouse gas (GHG) emissions in the subtropical region of Southern Brazil remains unknown. A three-year field study was developed aiming to evaluate the impact that an increase in crop management levels (high and very high) has on soil methane (CH4) and nitrous

22. Design and Analysis of a Novel Spacecraft for Mitigating Global Warming
ABSTRACT: A device called Huge Space Shield (HSS) has been put forward for mitigating global warming. This is a space tethers system, which use cables to connect a shielding surface and a mechanism control. In this study, orbital analysis was carried out to choose the best orbit for getting the best effect. Simulation studies were employed to understand the

23. 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

24. Population dynamics of Siderastrea stellata Verrill, 1868 from Rocas Atoll, RN: implications for predicted climate change impacts at the only South Atlantic atoll
ABSTRACT Coral reefs are one of the most vulnerable ecosystems to ocean warming and acidification, and it is important to determine the role of reef building species in this environment in order to obtain insight into their susceptibility to expected impacts of global changes. Aspects of the life history of a coral population, such as reproduction, growth an
