1. Evaluation of the Direct Interaction between Amino Acids and Glutathione-Coated CdTe Quantum Dots and Application in Urinalysis for Histidine Determination
The present work aimed to direct amino acid (AA) sensing by quantum dots (QD) and development of an analytical method for potential fast clinical tests. Notably, AA with a positive charge or neutral polar chains, namely L-histidine (His) and L-threonine (Thr), responded to glutathione-coated CdTe (GSH-CdTe) (ΔF ≤ 90%, variation of fluorescence intensity).

2. Cinética de secagem e propriedades termodinâmicas da polpa de patauá (Oenocarpus bataua Mart.)
Resumo O patauá é uma fruta amazônica que, devido às suas propriedades sensoriais e nutricionais atrativas, tem despertado o interesse da comunidade científica. Entretanto, o elevado conteúdo de umidade confere alta perecibilidade ao produto fresco. Assim, objetivou-se estudar a cinética de secagem convectiva e determinar as propriedades termodinâmic

3. AVALIAÇÃO DO DESEMPENHO DE UMA FASE SENSORA DE POLIURETANO POR MEIO DA ENERGIA DE GIBBS DE SOLVATAÇÃO E ESPECTROSCOPIA DE INFRAVERMELHO PARA DETERMINAÇÃO DE TOLUENO EM ÁGUA
A novel sensing phase of polyurethane was predicted by quantum chemical calculations as capable of detecting toluene, with the experimental results revealing a limit of detection of 1.4 mg L-1 in the determination of toluene in water samples. The quantum chemical computational strategy was validated by assessing the impact of the polymer matrix sensing phase

4. Isolation and characterization of phenol degrading yeasts from wastewater in the coking plant of Zarand, Kerman
Abstract Phenol and phenolic compounds are environmental pollutants present in industrial wastewaters such as coal tar, oil refineries and petrochemical plants. Phenol removal from industrial effluents is extremely important for the protection of environment. Usually, phenol degradation is carried out by physicochemical methods that are costly and produce ha

5. Experimental determination of vapor-liquid equilibrium data of binary mixtures of fatty acids through Differential Scanning Calorimetry / Determinação experimental de dados de equilibrio liquido-vapor de misturas binarias de componentes de oleos vegetais atraves da calorimetria diferencial exploratoria
This work will contribute to some unpublished data of phase equilibria of compounds that form the biodiesel, which arouses the interest immediately. Vapor-liquid equilibrium (VLE) data for three binary mixtures of saturated fatty acids have been successfully measured through differential scanning calorimetry (DSC). These data are of great interest to the ind

6. COVARIANCE COMPONENTS ESTIMATED BY BAYESIAN METHODOLOGY FOR BIOLOGICAL PARAMETERS OBTAINED BY NONLINEAR MODELS FOR BUFFALO BREED MURRAH / COMPONENTES DE COVARIÂNCIAS ESTIMADOS POR METODOLOGIA BAYESIANA PARA PARÂMETROS BIOLÓGICOS OBTIDOS POR MODELOS NÃO LINEARES PARA BUBALINOS DA RAÇA MURRAH
The aimed of this work was to study the adjustment of classical non linear models, Von Bertalanffy, Brody, Gompertz, Logistic to growing records of buffaloes of Murrah breed, raised on lowlands in the State of Rio Grande do Sul, and to estimate covariance components by Bayesian focus, for growing curve parameters with biological interpretation. In paper 01 t

7. Remoção de Pb(II) e Cr(VI) de efluentes industriais utilizando resíduos de Ipê (Tabebuia spp.), Maçaranduba (Manilkara spp.) e Pequiá (Caryocar spp.)
(Brazilian) Sawdust samples of Caryocar spp.; Manilkara spp. and Tabebuia spp. have been used for Cr(VI) and Pb(II) adsorption from water at 25oC. The series of adsorption isotherms were adjusted to a modified Langmuir equation from data obtained by suspending the sawdust with K2Cr2O7 or Pb(NO3)2 solutions, which gave the maximum number of moles adsorbed as

8. Alloying in GeSi:Si (001) epitaxial nanocrystals / Formação de ligas em nanocristais epitaxiais de GeSi:Si (001)
The structural and electronic properties of nanoscale materials strongly depend on the chemical composition, as well as their size and shape. A big variety of morphologies can be achieved by controlling the experimental conditions during the epitaxial growth of Ge on a Si(001) substrate. In particular, three-dimensional islands with well defined size and sha

9. Variance components for body weight in Japanese quails (Coturnix japonica)
The objective of this study was to estimate the variance components for body weight in Japanese quails by Bayesian procedures. The body weight at hatch (BWH) and at 7 (BW07), 14 (BW14), 21 (BW21) and 28 days of age (BW28) of 3,520 quails was recorded from August 2001 to June 2002. A multiple-trait animal model with additive genetic, maternal environment and

10. Eficiência de produção: um enfoque Bayesiano. / Production efficiency: a bayesian approach.
The use of stochastic production frontier with multiple-outputs has been waking up a special interest in areas of the economy that are confronted with the problem of quantifying the technical efficiency of firms. In the classic statistics, when it is confronted with firms that possess several outputs, cost or profit functions are more used to calculate that

11. Fibre distribution in the lungs and pleura of subjects with asbestos related diffuse pleural fibrosis.
The lungs from 13 cases of diffuse pleural fibrosis associated with a history of exposure to asbestos were examined. Samples were taken from the visceral pleura and central and subpleural zones of the lungs for histopathological and mineralogical studies. The fibre type, size, and number were estimated for each of these regions by transmission electron micro

12. Histometric study of the localisation of lymphocyte subsets and accessory cells in human Mantoux reactions.
Intradermal injection of purified protein derivative produced typical delayed type hypersensitivity reactions in five healthy human subjects. The major subpopulations of lymphocytes and certain accessory cells were located in frozen sections of biopsies of the lesions with monoclonal antibodies and immunohistochemical staining. The densities (expressed as nu
