1. Silicate fertilization in non-conventional vegetables in the southern region of Minas Gerais in Brazil
ABSTRACT Considering that the beneficial effects of silicon on human health and it´s accumulation in plants are little explored, studies of mineral nutrition in non-conventional vegetables are extremely relevant. Thus, the objective of this work was to identify non-conventional vegetables responsive to silica fertilization and evaluate the effect of fertili

5. DEVELOPMENT AND VALIDATION OF VOLTAMMETRIC METHOD FOR DETERMINATION OF IRON AND ITS CHEMICAL SPECIATION IN PORE WATER TO SEDIMENT OF THE PATOS LAGOON-RS / DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO VOLTAMÉTRICO PARA DETERMINAÇÃO DE FERRO E SUA ESPECIAÇÃO QUÍMICA EM ÁGUA INTERSTICIAL NO SEDIMENTO DA LAGOA DOS PATOS-RS
Sediments can act as accumulators as well as sources of pollutants. Depending on the port activities are in local growth rate by expanding the port of Rio Grande (RS), studies that show the location of the site investigation is important to predict the intake of iron in this environment. In this work, the chemical speciation of iron and measuring the concent

6. Desenvolvimento de uma metodologia para a estimativa de biomassa e de carbono em sistemas agroflorestais por meio de imagens orbitais / Development of a methodology to the estimation of biomass and of carbon in agroforestry systems for middle of orbits
Remarks indicate that naturals systems of the Earth are being affected for transformation about the ability of diverse region. Within the causes these changes, detach the emission of CO2 (Carbon Dioxide) way alteration in land use and land cover. The Amazonian region, in function of the occupation trajectory has received attention of the scientific community

8. Electrochemical and structural study of the electrode of hydroxide of nickel modified with cerium for stabilization of the phase 945;-Ni(OH)2 / Estudo eletroquímico e estrutural do eletrodo de hidróxido de níquel modificado com cério para estabilização da fase α-Ni(OH0)2
Ni(OH)2 is widely used as main active component for positive electrodes for secondary batteries such as Ni/Cd, Ni/Zn, Ni/Fe, Ni/H2 and recently in cell of Ni/MH. These accumulators show certain characteristics and they have several applications, such as: geostationary satellites, recharge feeding of computers, portable devices. Although the electrode of hydr

9. Autoradiographic method to screen for soil microorganisms which accumulate zinc.
An autoradiographic method was developed to screen for and isolate soil microorganisms which accumulate zinc (Zn). Diluted soil samples (Rubicon fine sand, Entic Haplorthods [pH 5.9]) were plated on soil extract-glucose agar containing radioactive 65Zn. After 7 days of incubation, individual colonies which accumulated sufficient 65Zn could be detected by aut

10. In Vitro Incorporation of Selenomethionine into Protein by Astragalus Polysomes 1
Selenium-accumulator plants synthesize selenium compounds that differ from those produced by nonaccumulators. To determine if there are any subcellular differences between accumulators and nonaccumulators in the use of selenomethionine in vitro, polysomes from Astragalus crotalariae (accumulator) and Astragalus lentiginosis (nonaccumulator) were translated i

11. l-Ascorbic Acid Metabolism in Vitaceae: Conversion to (+)-Tartaric Acid and Hexoses 1
The metabolic fate of l-ascorbic acid-1-14C and -6-14C has been investigated in two species in two genera of Vitaceae. Results suggest that ascorbic acid metabolism in the Vitaceae involves splitting the 6-carbon chain into 4- and 2-carbon fragments. The former, corresponding to C1 through C4 of ascorbic acid, is further oxidized to tartaric acid while the l

12. Exclusion of Selenium from Proteins of Selenium-Tolerant Astragalus Species 1
Protein fractions from three selenium-tolerant and three selenium-sensitive Astragalus species, grown in the presence of [75Se]selenate, were analyzed for their selenium content. Though tolerant species are known to accumulate considerably more selenium than do sensitive plants, protein fractions from the three selenium accumulators were found to contain sig
