13. Life cycle analysis of HCNG light-duty vehicle demonstration project
ABSTRACT The demonstration is an effective initiative to bridge the gap between a premature technology and its large-scale commercialization. A systematic method of LCA was used to perform the well-to-wheel analysis of a CNG light-duty truck operated with 0%, 15%, and 30% blends of hydrogen with compressed natural gas fuel under the system boundary of “per

14. Argamassas eco-eficientes com incorporação simultânea de material de mudança de fase e cinzas volantes
RESUMO Atualmente, a indústria da construção é um dos principais setores europeus responsáveis pelos elevados níveis de consumo de energia, extração de matérias-primas e produção de resíduos. Cada vez mais o consumo de energia proveniente de fontes renováveis e a reutilização de resíduos industriais constituem a única maneira de minimizar es

15. MONITORAMENTO DA COMPOSIÇÃO EM ÉSTERES DO BIODIESEL DO ÓLEO DE AMÊNDOA DA MACAÚBA (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) EM CONTATO DIRETO COM O AÇO CARBONO E O AÇO CARBONO GALVANIZADO
The oil from the macaúba (Acrocomia aculeata) fruit, a native palm in Brazil, has a real potential for the industrial production of biodiesel. This report describes an experimental work devoted to monitor the chemical behavior of the fatty acid methyl esters from oil of the macaúba fruit kernel and the leaching of metal elements into the biodiesel put in c

16. The devitrification kinetics of transparent silica glass prepared by gel-casting method
ABSTRACT The kinetics of the crystallization of cristobalite in the amorphous silica glass were studied for samples prepared by gel-casting and sintering in air. Avrami and rate equations were used to calculate the rate constants and the activation energy. The results showed that the crystallization obeys the first order and occurs mainly on the surface with

17. Exposição ocupacional ao mercúrio em cooperativas de triagem de materiais recicláveis da região metropolitana de São Paulo, SP, Brasil
Resumo A exposição ocupacional ao mercúrio (Hg) foi avaliada em 4 cooperativas de materiais recicláveis por meio de amostragens de ar em 9 áreas (monte de triagem, balança, prensa, sala de resíduos de equipamentos eletroeletrônicos-REEE, refeitório, escritório, empilhadeira, esteira e pátio externo). Das 83 amostras, apenas 14,5% apresentaram conc

18. Impacto do uso de resíduo de vermiculita no estado endurecido de argamassas
Resumo No processo de beneficiamento da vermiculita é gerado um resíduo fino para o qual atualmente ainda não foi desenvolvida uma aplicação que possibilite a utilização em larga escala. Uma alternativa que vem sendo estudada é a associação com cimento Portland em composições de argamassas e concretos, em função da composição química do res�

19. Cattle Manure Bioconversion Effect on the Availability of Nitrogen, Phosphorus, and Potassium in Soil
ABSTRACT The efficiency index (EI) refers to the ratio of nutrients mineralized/made available in the soil to the total amount of nutrients added by organic fertilizer. Therefore, understanding the EI is essential for recommendation of organic fertilization. The aim of this study was to evaluate the availability through mineralization and the efficiency inde

20. Synthesis and characterization of nanostructured TiO2 and TiO2/W thin films deposited by co-sputtering
ABSTRACT Nanostructured TiO2 and TiO2/W thin films were deposited on Corning glass substrates by RF and DC magnetron co-sputtering at room temperature, using three targets of TiO, Ti and W. After deposition, samples were subjected to an annealing treatment in air at 500 °C for 3 hrs. The effect of the annealing treatment and tungsten addition to the TiO2 ma

22. Salmonella Enteritidis in Layer Farms of Different Sizes Located in Northern China: On-Farm Sampling and Detection by the PCR Method
ABSTRACT Salmonella enterica subspecies enterica serotype Enteritidis (SE) has caused foodborne infections over decades. It is transmitted mainly from contaminated eggs to humans. SE is commonly present in layer houses, and closely interacts with environmental factors. The objective of the present study was to develop a viable PCR method to identify SE in en

23. INFLUÊNCIA DO ENVELHECIMENTO ACELERADO EM FLARES MAGNÉSIO/PTFE/FPM
Magnesium/PTFE/FPM decoy flares, also named conventional flares, were designed in order to protect combat aircraft from the threat caused by infrared-guided missiles. Adverse storage or transport conditions may cause reactions that deteriorates chemical properties of the conventional flares, causing the aging and compromising its performance. The aim of this

24. Optimization and application of spray-drying process on oyster cooking soup byproduct
Abstract Oyster drying processes have produced a large amount of cooking soup byproducts. In this study, oyster cooking soup byproduct was concentrated and spray-dried after enzymatic hydrolysis to produce seasoning powder. Response surface methodology (RSM) was performed on the basis of single-factor studies to optimize the feeding temperature, hot air temp
