Características fisiológicas e ecológicas de isolados de rizóbios oriundos de solos ácidos e álicos de Presidente Figueiredo, Amazonas
Hara, Francisco Adilson dos Santos;Oliveira, Luiz Antonio de;
Acta Amazonica , 2004, DOI: 10.1590/S0044-59672004000300002
Abstract: some isolated rhizobias, besides fixing n2, are also able to solubilize low soluble phosphates, making the p available both for plants and for themselves. some factors like toxic al and acidity, as in some amazonian soils, may decrease the population of these microorganisms. the present study evaluated the nodulation ability, tolerance to acidity and toxic aluminum, as well as the ability to solubilize ca and al phosphates of rhizobia isolated from agricultural soils the municipality of from presidente figueiredo, am. samples of soil under agricultural cultivation were collected and used as a source of inoculum for the cowpea bean. some rhizobia isolates were tested for tolerance to acidity and toxic al, as well as to verify their abilities to solubilize phosphates. the soil samples contained rhizobia populations capable of inducing the nodulation and improving the aerial biomass of cowpea bean under acidity (ph 4,5) and alic (2 cmolc al.l-1) conditions. the rhizobia population from the soil samples idnetified as inpa-pf2, inpa-pf3, inpa-pf4, inpa-pf5, inpa-pf13, inpa-pf15, inpa-pf22 and inpa-pf24 promoted increases of aerial biomass when compared to the control tratment (absence of inoculum). twenty-five percent of the isolates were tolerant to acidity and 23% to al. the ca phosphate was solubilized by 39% of the isolated rhizobia. however, just one isolate presented high solubilization index. the al phosphate solubilization ability was identified in 67% of the isolates. the majority of the isolates that solubilized ca phosphate (76.5% of the lineages) also solubilized the al phosphate.
Características fisiológicas e ecológicas de isolados de rizóbios oriundos de solos ácidos de Iranduba, Amazonas
Hara, Francisco Adilson dos Santos;Oliveira, Luiz Antonio de;
Pesquisa Agropecuária Brasileira , 2005, DOI: 10.1590/S0100-204X2005000700007
Abstract: aluminum content and acidity of amazonian soils may decrease the population of rhizobia, which fix n2, solubilize insoluble phosphates, and increase the availability of p in the productive systems. the aim of this work was to evaluate the nodulation capacity, tolerance to acidity and to toxic aluminum, as well as the capacity to solubilize calcium and aluminum phosphates of rhizobia isolates obtained from farm soil samples of iranduba, am, brazil. soil samples were used as source of inocula for cowpea bean, and isolates were extracted from the nodules, in order to test tolerance and solubilization. soil samples presented populations of rhizobia with potential to be used as source of inocula for cowpea. inpa-m10 tended to surpass all other inocula in relation to the shoot dry matter yield. there was a significant correlation between the number and mass of the nodules, indicating that isolated rhizobia presented nodules of similar sizes. the sensibility to acidity and aluminum was showed by 43% of the isolated rhizobia; the other presented itself as tolerant. the solubilization of calcium phosphate was observed in the presence of 57% of isolated rhizobia. the same proportion occurred in the solubilization of aluminum phosphate.

Revista Uniandrade , 2012,
Abstract: A violência contra crian as e adolescentes é t o antiga como a própria história da humanidade, sendo um grave problema de saúde que se apresenta no cotidiano do profissional de Enfermagem. Discutir os cuidados do Enfermeiro frente ao atendimento à crian a e o adolescente que sofre de violência sexual e abordar alguns aspectos legais que envolvem esta problemática. Realizou-se revis o de literatura nas bases de dados da Scielo e outras Revistas Eletr nicas de Saúde, em dois Trabalhos de Conclus o de Curso, no período de 2000 a 2011, nas legisla es sobre o assunto e também coletou-se dados nos relatórios de programas da Secretaria Municipal de Saúde (SMS) de Curitiba-Pr. Utilizou-se os seguintes descritores: “abuso”, “violência”, “sexual”, “crian a”, “adolescente”, “papel do Enfermeiro”, “maus tratos” sob a forma combinada ou isoladamente. Para que haja uma melhor compreens o sobre a temática da violência sexual que acomete a crian a e o adolescente no cotidiano da equipe de Enfermagem, apresentamos neste artigo os seguintes tópicos: as formas de violência intrafamiliar; os aspectos legais da violência sexual contra a crian a e o adolescente descritos no Estatuto da Crian a e do Adolescente; o Código de ética dos Profissionais de Enfermagem; o papel do Enfermeiro frente à crian a/adolescente vitimados sexualmente e a importancia da inclus o do tema violência sexual na grade curricular de Enfermagem. Percebe-se que mesmo com a crescente aten o em rela o ao atendimento à crian a/adolescente vitimados sexualmente, ainda há dificuldades a serem sobrepostas pelos profissionais de Enfermagem para que haja um atendimento efetivo a este público.

Abstract: molecular size fractionation of the natural organic matter (nom) in water samples from the serra de itabaiana national park (brazil) was used to characterize the temporal behavior of metal ion complexation. a special five-stage tangential-flow ultrafiltration device was used to separate nom in six size fractions (f1: > 100; f2: 100-50; f3: 50-30; f4: 30-10; f5: 10-5; f6: < 5 kda). the distribution patterns obtained for one in natura sample showed that metals (al, ba, cr, cu, fe, mn, ni, pb and sr) were preferentially complexed by the f1 fraction, which contained higher concentration of dissolved organic carbon (doc). the following decreasing order of carbon distribution in the different fractions was obtained: f1 >> f3 > f2 = f4 > f6 > f5. fractions f2 and f5 were the most humified, and f6 the least. new distributions of doc and metals were observed after 30 days when high concentrations of metals were added to filtered samples. highest doc was still found in f1, with carbon contents decreasing in the following order: f1 > f2 > f3 > f4 > f5 > f6. the studied metals presented similar and homogeneous distributions in all fractions. values of log k were similar for samples in natura and 30 days after addition of metals (7.1 and 7.0, 6.6 and 6.9, and 7.2 and 7.0 for al, cu and fe-nom, respectively), indicating a new dynamic equilibrium in the metals distribution after 30 days. the species formed between nom and spiked metals showed distribution patterns that changed as a function of complexation time, indicating a transformation of the nom binding sites, suggesting that the collective effect of the fractions is more important than individual site properties, and confirming that the most humified fractions exert a large influence on the complexation of metals in aquatic environments.
