Para o calculo do IQA em aguas subterraneas neste estudo, foram determinadas as variaveis pH, solidos totais (somatorio de solidos totais dissolvidos e solidos totais suspensos), fluoreto, cloreto, dureza e N-nitrato.
(19) baseou-se no mesmo principio, a formulacao matematica utilizada no IQA NSF e CETESB, em que o produto dos valores de qualidade das aguas subterraneas a partir das variaveis escolhidas atraves da opiniao de especialistas no assunto (qpH, qsolidos totais, qcloreto, qfluoreto, qdureza e qnitrato), e elevado ao peso definido para cada variavel de acordo com a importancia das mesmas, conforme a Equacao 01:
Os modelos matematicos construidos para o calculo do IQA em aguas subterraneas foram elaborados a partir de notas de qualidades aplicadas para cada variavel, sendo utilizada a nota 37 para a qualidade aceitavel no final de intervalo para cada variavel, tomando-se como referencia a os valores recomendados pela Portaria 2.914 de 2011 do Ministerio da Saude.
As aguas da Vila do Conde apresentaram qualidade impropria nos dois periodos, inclusive o poco utilizado para o abastecimento geral da sua populacao, com valores de IQA variando de 16 a 32.
Na comunidade Maranhao as aguas apresentam um padrao melhor refletido pelos indices mais elevados de IQA, ao contrario dos resultados de Vila do Conde, cujos valores de IQA mostram a degradacao dos aquiferos refletindo na qualidade das aguas subterraneas utilizadas para abastecimento da populacao.
In this paper, an objective NR IQA, S, is proposed to assess the quality of the tone mapped LDR image.
Table 3 compares NR IQA scores, which represent the quality of tone mapped LDR images.
Attempts have been made to overexpress the genes responsible for producing the enzymes involved in the rate-limiting steps of these processes with the aim of improving the yields of the associated IQAs. For example, the overexpression of C.
The recent identification of the transcription factors CjWRKY1 and CjbHLH1 as possible general regulators in IQA biosynthesis using a transient RNAi screening system could represent a significant discovery in the field and provide significant improvements in the yields of IQAs by enabling the regulation of the transcription processes associated with their production.
As well as providing improvements in the yield, improvements in the quality of the IQAs are perhaps more desirable, in that although increases in metabolic diversity would be useful for drug discovery, the reduction of the metabolic diversity is critical for the facile preparation of pure compounds.
The present investigation has opened up a new avenue for the microbial production of plant secondary metabolites, using IQAs as the model.
In this review, we have provided a summary of the progress that has been made towards the biochemical and molecular biological characterization of the IQA biosynthetic pathways using cultured C.
