Effect of pH and dye concentration on the n-octanol/water distribution ratio of phenothiazine dyes: a microelectrode voltammetry study
(Elsevier B.V., 2014-10-20)
Microelectrode voltammetry was employed to gain information on the n-octanol/water partition ratio of phenothiazine dyes. the data were obtained as a function of pH and dye concentration in aqueous solutions. All the dyes ...
Go/N ratio in tropical soils from Brazil
(2015-01-01)
The geotechnical behavior of tropical soils is complex and cannot be supported only by the classical soil mechanics. The Standard Penetration Test (SPT) is broadly used for geotechnical site characterization. However, it ...

The interaction between N-category and N-ratio as a new tool to improve lymph node metastasis staging in gastric cancer: Results of a single cancer center in Brazil
(ELSEVIER SCI LTD, 2011)
Background: Depth of tumor invasion (T-category) and the number of metastatic lymph nodes (N-category) are the most important prognostic factors in patients with gastric cancer. Recently, the ratio between metastatic and ...
Unbiased approach to diagnose the nutrient status of red guava (Psidium guajava)
(2012-09-30)
Fertilization of guava relies on soil and tissue testing. The interpretation of tissue test is currently conducted by comparing nutrient concentrations or dual ratios with critical values or ranges. The critical value ...

The mechanism of 234U 238U activity ratio enhancement in karstic limestone groundwater
(Elsevier B.V., 1993-01-05)
Experimental etch/leach of Carboniferous Limestone gravels on a laboratory time-scale has demonstrated that 234U 238U activity ratios (AR's) greater than the radiochemical equilibrium value may be generated on short ...
N-vinylimidazole-N-vinyl-2-pyrrolidone copolymers. Part I. Reactivity ratios, solubility and viscosimetric study
(JOHN WILEY & SONS LTD, 1998)
Copolymers of N-vinylimidazole M with N-vinyl-2-pyrrolidone (VP), (VI-co-VP) were obtained by radical polymerization using alpha,alpha'-azobisisobutyronitrile as initiator. The copolymers were characterized by H-1 NMR and ...
Sex ratio and morphological characteristics of Rufous Gnateaters, Conopophaga lineata (Aves, Passeriformes) in Atlantic forest fragments
(FUNDACAO ZOOBOTANICA RIO GRANDE SUL, MUSEU CIENCIAS NATURAIS, 2009)
Unequal sex ratios lead to the loss of genetic variability, decreasing the viability of populations in the long term. Anthropogenic activities often disturb the natural habitats and can cause alterations in sex ratio and ...
