15. Adsorção de o-xileno em argila fluidgel organofílica em fase gasosa / Adsorption of o-xylene onto organoclay fluidgel in gas phase
The industrial growth allied to use of petroleum products generate numerous volatile organic compounds (VOC) that are continuously emitted to the atmosphere, degrading air quality and causing serious problems to human health and environment. Among the VOC, the so-called BTEX (benzene, toluene, ethyl benzene, and xylene), are the most important in terms of to

18. Níveis de clorofórmio na água potável distribuída pela estação da tratamento de Boa Vista, Roraima e relação com insuficiência renal
The public water supply in terms of quality and quantity is a growing concern of mankind, because of water scarcity and deteriorating quality of water sources. Disinfection is the primary purpose of chlorination and more common, but it appears as the by-products like THMs products of the reaction between chemicals that are used to treat oxidative and organic

19. Challenges and potential of organic production: analysis of Project Cultivating Good Water (CAB), Parana Basin 3 / Os desafios e potencialidades da produÃÃo orgÃnica: anÃlise do Projeto Cultivando Ãgua Boa (CAB), na Bacia do Paranà 3
Family farming in organic agriculture sees a strategy to promote their economic and social development, adding value to their products. This new perspective has been constructed and expressed in the idea of "sustainability in the field." In this sense, the family farm and agro-ecological production, combined with the practices conscious consumption, can occu

20. Ozone application in water sources: effects of operational parameters and water quality variables on ozone residual profiles and decay rates
Systematic ozonation tests were conducted by means of a mobile pilot plant. Water source 1 was a low turbidity stream with very low solids content and very low turbidity, apparent color and alkalinity. Water source 2 was reservoir water with higher turbidity, solids content and alkalinity than source 1. The ozone plant was a counter-current contactor compose

22. Efeito da clorexidina e flúor na resistência coesiva da estrutura dental irradiada e não irradiada
Radiation therapy significantly reduces the resistance of the tooth structure and the damage is potentially higher in the organic matrix. The use of products that promote the stabilization of collagen and / or agents to intensify the cross-links may provide less damage to the resistance of teeth irradiated. This study aimed analyze the effect of the use of c

23. Utilização da dupla filtração, oxidação e adsorção com carvão ativado pulverizado no tratamento de água eutrofizada / Use of two-stage filtration, oxidation, and powdered activated carbon adsorption in the treatment of eutrophic waters
One problem that frequently arises in water treatment plants is the inadequacy of the chosen treatment processes with respect to the source water quality. Several studies have shown that processes encompassing conventional water treatment have limited capability to remove compounds associated with algae and their by-products. In Brazil, a technology known as

24. Acúmulo de ricina em sementes de mamona e silenciamento do gene em plantas geneticamente modificadas
Castor bean (Ricinus communis L.) is an oilseed of great economic and social importance. The oil extracted from its seeds is used in biodiesel production and as raw material for chemicals, cosmetics and lubricants. Besides the oil extracted from the seeds, their production chain generates side-products, which can be used as organic fertilizer of good quality
