13. Life Cycle Assessment (LCA) and Wind Power Generation: Application of the Methodology and the Generator to Power System
ABSTRACT Sustainability and economics are current issues in the generation of electricity. The energy matrix is diversified and some forms have stood out, such as wind. Some tools have been developed to improve project efficiency, one of which is Life Cycle Assessment (LCA). This presents solidity when assisting projects financially and environmentally, eval

14. Assessment of genetic mutation frequency induced by oxidative stress in Trypanosoma cruzi
Abstract Trypanosoma cruzi is the etiological agent of Chagas disease, a public health challenge due to its morbidity and mortality rates, which affects around 6-7 million people worldwide. Symptoms, response to chemotherapy, and the course of Chagas disease are greatly influenced by T. cruzi‘s intra-specific variability. Thus, DNA mutations in this parasi

15. Carbon footprint assessment for a local branded pure milk product: a lifecycle based approach
Abstract This paper provides a simplified life cycle based assessment for a local branded pure milk product, to measure its related carbon footprint, including production of raw milk, dairy processing, transportation of milk product and disposal of packaging waste. The results show that the total carbon footprint of the pure milk is 1120g CO2/L. The producti

16. Experimentally Validated Combustion and Piston Fatigue Life Evaluation Procedures for the Bi-Fuel Engines, Using an Integral-Type Fatigue Criterion
Abstract A relatively complete procedure for high cycle fatigue life assessment of the engine components is outlined in the present paper. The piston is examined as a typical component of the engine. In this regard, combustion process and transient heat transfer simulations, determination of the instantaneous variations of the pressure and temperature in the

18. Assessing environmental impacts using a comparative LCA of industrial and artisanal production processes: "Minas Cheese" case
This study uses the Life Cycle Assessment (LCA) methodology to evaluate and compare the environmental impacts caused by both the artisanal and the industrial manufacturing processes of "Minas cheese". This is a traditional cheese produced in the state of Minas Gerais (Brazil), and it is considered a "cultural patrimony" in the country. The high participation

22. Life Cicle Inventory for Lead Azide Manufacture
ABSTRACT: Like any other manufactured chemical compounds, explosives are produced using chemical reactants and other utilities (steam, heat, compressed air, feed water and electricity) and generate a set of environmental impacts (waste water, solid and water residue and waste heat, for example). On top of that, one can count the intrinsic hazard characterist
