1. Avaliação da energia incorporada e da emissão de CO2 em recipientes para refrigerantes: PET versus vidro
RESUMO Este artigo busca avaliar e comparar qual material (PET ou vidro) proporciona um ciclo de vida mais sustentável para os recipientes utilizados no envase de refrigerantes. Foram comparados quatro recipientes de vidro - três retornáveis e um descartável - com cinco recipientes em polietileno tereftalato (PET) - três descartáveis produzidos com mat

2. Energy embodiment in Brazilian agriculture: an overview of 23 crops
The amount of energy required to produce a commodity or to supply a service varies from one production system to another and consequently giving rise to differing levels of environmental efficiency. Moreover, since energy prices have been continuously increasing over time, this energy amount may be a factor that has economic worth. Biomass production has a v

3. Análise do ciclo de vida energético de projeto de habitação de interesse social concebido em light steel framing
A indústria de construção civil no Brasil possui grande importância tanto social quanto econômica, porém é geradora de mais de 50% dos resíduos sólidos urbanos e consumidora de grande quantidade de matéria-prima, energia e água. Desta forma o setor é estratégico sob o ponto de vista ambiental uma vez que pequenas mudanças em seus processos ocas

4. Incorporação de energia na vida útil de uma colhedora autopropelida de cana-de-açúcar / Energy embodiment in life cycle of a self-propelled sugarcane harvester
The energy subject is one of the main challenges of 21st century. The geopolitical and environment aspects, they are concern sources to the current economic model. Brazil presents advantages in comparison to the world due to the use of renewable energy. Since 2007, products from the sugarcane have assumed the first place as a renewable source in the Brazilia

5. Life cycle assesment of soybean. / Analise do ciclo de vida da soja.
The objective of this study is to assess the soybean life cycle to quantify the environmental and economic contributions at each stage of soybean and soybean products production, transport and processing phases. In order of that, it were used the Embodied Energy Analysis, the Material Intensity Analysis and the Emergy Synthesis as well other economic and soc

6. Face a ecaF : quando "tu" dança / Face a ecaF : when "other" dance
The objective is to understand the nature of the creative process observing the body experience that embodied in the tension between opposite forces in the dance movement. This study concentrated in the dance language following the tracks of the energy performance that emanates from the body. "Who dances in me when I dance? This "who" may not have a concrete

7. Optimal protein-folding codes from spin-glass theory.
Protein-folding codes embodied in sequence-dependent energy functions can be optimized using spin-glass theory. Optimal folding codes for associative-memory Hamiltonians based on aligned sequences are deduced. A screening method based on these codes correctly recognizes protein structures in the "twilight zone" of sequence identity in the overwhelming majori

8. Fragilities of liquids predicted from the random first order transition theory of glasses
A microscopically motivated theory of glassy dynamics based on an underlying random first order transition is developed to explain the magnitude of free energy barriers for glassy relaxation. A variety of empirical correlations embodied in the concept of liquid “fragility” are shown to be quantitatively explained by such a model. The near universality of
