1. Uso de sistemas modulares vegetados para promoção da saúde urbana e atenuação do estresse térmico
RESUMO O processo de urbanização possui efeitos significativos no microclima local, resultando no surgimento das ilhas de calor e comprometimento das condições térmicas no interior de habitações. A aplicação de sistemas modulares vegetados em telhados ou coberturas surge como alternativa à melhoria das condições térmicas no interior de habitaç�

2. Behaviors of Embrittlement and Softening in Heat Affected Zone of High Strength X90 Pipeline Steels
Abstract The embrittlement and softening behaviors in heat affected zone of X90 pipeline steel were studied, and the influence of weld thermal cycle on microstructure and mechanical properties were discussed by combining the effect of peak temperature on the phase transition point (Ar3). Results show that there are embrittlement and softening zones existed i

3. Avaliação quantitativa e qualitativa do emprego de paredes como nova perspectiva para captação de água de chuva
RESUMO A poluição dos mananciais de abastecimento e a necessidade de se buscar água, cada vez mais distante, agregam à água tratada alto valor monetário, sendo a captação e a utilização da água de chuva uma forma de reduzir custos. Nos grandes centros urbanos, ocorre a formação de ilhas de calor, as quais favorecem a ocorrência de chuvas convec

4. GREEN ROOF: SIMULATION OF ENERGY BALANCE COMPONENTS IN RECIFE, PERNAMBUCO STATE, BRAZIL
ABSTRACT Green roof is a technology that consists of the use of soil and vegetation installed in the roof of buildings, being a great solution to combat heat islands. Thus, this study aimed to compare micrometeorological changes and their effect on the energy balance of non-vegetated (slab) and vegetated building roofs by means of a simulation model calculat

5. Formation of Microphases and Constituents from Remaining Austenite Decomposition in API X80 Steel Under Different Processing Conditions
AbstractThe main goal this work is to evaluate the occurrence of the constituents and microphases observed in as-received API X80 pipe through the microstructures transformed from rich-carbon remaining austenite obtained via heat treatments. These heat treatments comprised austenitization at 1000 °C for 30 minutes, followed by annealing at 700 °C, 623 °C,

6. São Paulo urban heat islands have a higher incidence of dengue than other urban areas
Urban heat islands are characterized by high land surface temperature, low humidity, and poor vegetation, and considered to favor the transmission of the mosquito-borne dengue fever that is transmitted by the Aedes aegypti mosquito. We analyzed the recorded dengue incidence in Sao Paulo city, Brazil, in 2010-2011, in terms of multiple environmental and socio

7. Temperatura de la superficie terrestre en diferentes tipos de cobertura de la Región Andina Colombiana
This study assessed the relationship of Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI) with land surface temperature (LST), using Landsat images of La Vieja river watershed, in the Andean region of Colombia. We evaluated land covered by Andean forest, forest plantation, coffee, pasture and urban area. Negative corr

8. Efeitos do revenimento realizado a baixa temperatura na resistência ao impacto em aços carbono e ligados temperados
This work has as main objective the determination of mechanical behavior, specially the impact resistance of martensitic structures based on carbon and on alloyed steels. The main concern is the response of these alloys when tempering at low temperatures (below 180C). Heat treatments were performed by quenching in water and oil in order to determine the seve

9. O CAMPO TERMO-HIGROMÉTRICO INTRA-URBANO E A FORMAÇÃO DE ILHAS DE CALOR E DE FRESCOR URBANAS EM SANTA MARIA/RS / THE THERMO-HYGROMETRIC FIELD INTRA-URBAN AND FORMATION OF HEAT ISLANDS AND URBAN COOL IN SANTA MARIA/RS
Urbanization and the changes imposed by man disturb the complex natural system, modifying the elements and characteristics of climate on a local scale. Considering the influence of urbanization as derived from the fact that the local climate and responsible for the generation of an urban environment specifically, this work was to analyze the field thermo-hyg

10. A influência da vegetação sobre o clima urbano de Palmas-TO / The influence of vegetation on urban climate of Palmas-TO
This study addresses the issue of urban climate. It is based on the assumption that vegetation may act to improve the microclimate conditions of cities, by reducing the temperature of the air, which is very important in warm climates. Aims to investigate the influence of vegetation on urban climate in Palmas, capital of the province of Tocantins. It was base

11. Urban climate Ponta Grossa-PR: an approach to climate dynamics in subtropical Brazilian city average / Clima urbano em Ponta Grossa - PR: uma abordagem da dinâmica climática em cidade média subtropical brasileira
The human being has led to changes in climate through the transformation of nature, whether for its occupation of space, is to develop its activities. To the extent that the man is concentrated in certain áreas, pressure on the natural conditions increases. The city is one of the best examples of the concentration of people and activities in one place and a

12. Rainfall interception in species of Sibipiruna (Caesalpinia pluviosa DC.) and Tipuana (Tipuana tipu O. Kuntze) / Interceptação da chuva nas espécies de Sibipiruna (Caesalpinia pluviosa DC.) e Tipuana (Tipuana tipu O. kuntze)
Climate studies are receiving more attention in the environmental field, especially concerning air quality (atmosphere pollution), thermal comfort (heat islands) and pluvial impacts (urban flood generators). In the latter, the rain causes disturbance of the population and the competent public organ, due the extreme events that are increasing in the whole wor
