1. Multivariate Analysis: Use of Doehlert Design (DD) for Optimization of a Simple Sample Preparation Procedure for the Determination of Inorganic Constituents in Cocoa Beans Employing Microwave Acid Digestion and ICP OES
This study presents a microwave-assisted procedure for sample preparation of cocoa beans using diluted HNO3 with H2O2 for the determination of Ba, Ca, Cu, K, Mg, Mn, P, S, Sr and Zn by inductively coupled plasma optical emission spectrometry (ICP OES). Doehlert modified design was used for optimization of experimental condition, and the volume of H2O2 (0, 0.

3. Excesso de ruído no oscilador paramétrico ótico / Excess noise in optical parametric oscillator
In spite of the fact that the Optical Parametric Oscillator (OPO) is one of the most known experiments related with quantum information research, its experimental results did not have a good agreement with the theory, in the above threshold regime, because of an unexpected excess noise in the phase quadrature on its beams. In this work we sistematicaly prese

4. Use of Doehlert design for optimizing the digestion of beans for multi-element determination by inductively coupled plasma optical emission spectrometry
Neste trabalho a otimização de um procedimento rápido e de baixo custo para digestão ácida de feijão foi desenvolvida. Elementos essenciais (Ca, Cu, Fe, K, Mg, Mn, Ni, P, Zn) e não essenciais (Al, Ba, Sr) foram determinados por espectrometria de emissão óptica com plasma indutivamente acoplado (ICP OES). Foi utilizado planejamento fatorial de dois n

5. Variabilidade espacial de atributos fisico-hidricos do solo cultivado com feijão irrigado sumetido a diferentes sistemas de preparo / Soil physical-hydric attributes spatial variability doe diferent irrigated bean tillage systems
Since last decades irrigation practices are recognized as major water consumers, requiring specific agricultural producers education and awareness on water use and supply. Recent research reports indicate significant water economy, crop yielding as well as contribution to sustainable agricultural development, if direct seedling, when compared with convention

6. Optical properties of etiolated plant tissues
Etiolated tissues of several plants are multiple bundles of fiber optics capable of coherent transfer of light over at least 20 mm. The acceptance angles (the angles at which light can be intercepted and then internally reflected longitudinally) for mung beans, oats, and corn are 47°, 59°, and 52°-54°, respectively. The shapes of the curves that describe
