1. Zeólita NaA sintetizada sobre fibra de vidro como estratégia para otimização do abrandamento de águas duras
NaA ZEOLITE SYNTHESIZED OVER FIBERGLASS AS A STRATEGY FOR OPTIMIZING HARD WATER SOFTENING. Zeolite NaA has been successfully synthesized over glass fiber surface previously activated by alkaline treatment. By varying the time of the treatment and the amount of silica and alumina precursors used in the reaction mixture, a sample with higher zeolite concentrat

2. Hepatitis C virus genotypes and associated risk factors in the state of Pará, Northern Brazil
Abstract Background Despite the emergence of more effective therapies, hepatitis C virus (HCV) infection remains a serious public health problem at the global level. Currently, this virus is classified into seven genotypes and 67 subgenotypes, which in turn are distributed heterogeneously in Brazil and worldwide. Studies have shown that this genetic diverge

3. 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

4. Produção de agregado sintético de argila com reaproveitamento de resíduo de vidro
RESUMO É objetivo da construção civil, reduzir o peso das estruturas e consequentemente os custos com as fundações. A substituição de britas por agregados leves é a alternativa mais utilizada. No entanto, sobretudo no Brasil, só existe uma única fábrica de agregados leves localizada em São Paulo, sendo oportuna a pesquisa de matériasprimas para

5. Editorial
Numerous silicates based wastes have been produced and considered for recycling and reuse. Among them, glass cullet is one of the most common silicate wastes and has considerable volume in the cities wastes. A big amount of this waste is recycled by the glass industry but another part is dumped in the cities garbage deposits. In the last few decades there ha

6. Compositos hibridos de poli (tereftalato de etileno) (PET) / fibra de vidro (FV) / modificador de impacto (E-MA-GMA) / Hybrid composites of PET / modifier of impact (E-MA-GMA) fibre glass
An important application of poly(ethylene terephtalate) - PET - to be considered, and still not well explored, is its re-use in other different sectors, such as the obtaintion of PET composites reinforced with fibre glass (FG) and elastomer, for several applications in the engineering area. In this way, it is necessary a systematic study of several PET compo

7. Programa de incentivo à destinação correta do vidro / Program of incentives to assign correct of glass
Many actions and concerns that aim the propoer destination of urban solid waste, guided to most correct glass packing management, do not get success due to the lack of adequate and very simple basic informations, which can be easily afforded. Trying to miminize the effect of the indiscriminate or unconscious discharge that conduct to an inadequate glass pack

8. GLASS AND GLASS-CERAMICS WITH HIGH METAL CONCENTRATION OF FROM INDUSTRIAL WASTES / Vidros e vitrocerâmicos com alta concentração de metais obtidos a partir de resíduos industriais
The reuse of industrial waste materials is considered as an important source of raw-materials to be employed at new products. However proper criteria is needed in order to obtain vitreous materials from industrial solid wastes like solid galvanic waste (metallurgical industry) as main raw material. Ajusting the composition silica fine powder (ceramic industr

9. NEW ALTERNATIVE FOR REUSE HAZARDOUS WASTE FROM THE PRIMARY ALUMINUM PRODUCTION PROCESS (SPL): PRODUCTION OF THE OPAL GLASS AND FRITS / Nova alternativa para reaproveitamento do resíduo perigoso gerado na produção de alumínio primário (SPL): obtenção de vidros opacos e fritas.
The solid waste from deteriorated linings of cells in the aluminum metal production is called spent pot lining or SPL. Because of the presence of leachable cyanide and fluoride compounds the SPL is classified by internationals standards and the Brazilian Association of Technical Standard (ABNT) as hazardous waste. The purpose of the present work is to evalua

10. Desenvolvimento, avaliação e aplicações de novas fases para extração por sorção em barra de agitação (SBSE) / Development, evaluation and applications of new phases for stir bar sorptive extraction (SBSE)
The development of different kinds of bars for stir bar sorptive extraction (SBSE) was described in this work. This technique has been applied for the extraction of organic compounds from aqueous matrices due to their sorption on the stir bar. Stir bars are composed of a magneto inserted into a glass tube and coated with a polydimethylsiloxane (PDMS) layer.

11. Comparison between glass bottles and PET bottles for energy utilization and carbon dioxide emission, using environmental life cycle assessment / Comparação do consumo de energia e emissão de CO2 entre garrafas de PET e de vidro, utilizando analise ambiental de ciclo de vida
Nowadays the packing market presents great evolution, this happens because the packing choice, which are used in several products, that also consider the search for c1eaner technologies, and not on1y the costs and the consumer s preference. To manage packing choice, which get to affect less the environment, is used LIFE CYCLE ANAL YSIS, this method gets to m
