14. Reações de obtenção de NOx empregado no processo Humifert para a produção de compostos organofosfatados. / NOx reactions applied in a organophosphated compounds production by Humifert process.
Humiphert process is an alternative used for producing phosphated compound fertilizers with a slower solubilization when compared to other traditional fertilizers, resulting in a longer period of plant nutrition. During the process, phosphatic rocks are used along with some sort of limitation according to the normal development, both by their lower content p

16. Transporte de nutrientes e bactÃrias por escoamento superficial devido a aplicaÃÃo de Ãgua residuÃria da suinocultura no solo
The swine activity is a characteristic of the south region of Brazil, and in the State of Parana it has been of outstanding economical and social importance. However, this activity presents low environmental quality due to the generation of great volumes of liquid residues with elevated pollutant power due to his physical, chemical and microbiological charac

17. O ÍNDICE DE SUSTENTABILIDADE AMBIENTAL DO USO DA ÁGUA (ISA) COMO FERRAMENTA DE CONTRIBUIÇÃO ÀS POLITICAS PÚBLICAS DE DESENVOLVIMENTO E CONSERVAÇÃO NA BACIA DO RIO BACANGA, SÃO LUÍS/ MA. / INDEX FOR ENVIRONMENTAL SUSTAINABILITY OF WATER USE (ISA) AS A TOOL FOR CONTRIBUTION TO THE POLICIES PUBLIC DEVELOPMENT AND CONSERVATION IN BACANGA RIVER BASIN, SÃO LUIS / MA.
A hydrographic basin is a complex environmental system, resulting from the interrelations between the physical-natural and socioeconomic subsystems. Its identity as the unifying of environmental processes and human interference is leading to its adoption as a research unit. It allows from the analysis of the physical-chemical, biological and socioeconomic fa
