1. Concentration and accumulation of micronutrients in robust coffee
ABSTRACT. Knowledge on the dynamics of micronutrients in coffee tree assists nutritional diagnosis and fertilization management. Therefore, the objective of this study was to evaluate the concentration and accumulation of micronutrients in the leaves and fruits of Coffea canephora. The experiment was managed in crops propagated for 2.5 years in a split-plot-

2. Photosynthetic induction and activity of enzymes related to carbon metabolism: insights into the varying net photosynthesis rates of coffee sun and shade leaves
The shade leaves of coffee (Coffea arabica L.) apparently retain a robust photosynthetic machinery that is comparable to that of sun leaves and can fix CO2 at high rates when subjected to high light intensities. This raises the question of why the coffee plant would construct such a robust photosynthetic machinery despite the low photosynthetic rates achieve

3. Eficiência de estimadores robustos a observações discrepantes em modelo de regressão multivariada com aplicação na análise sensorial do café / Robust estimators efficiency to outliers in multivariate regression with application in the sensory analysis of coffee
Dada a sensibilidade do método de mínimos quadrados à presença de observações discrepantes, é sabido que as estimativas de mínimos quadrados são afetadas pela presença de uma ou mais dessas observações. Frente ao exposto, esse trabalho foi realizado com o objetivo de pesquisar o efeito de observações discrepantes no ajuste de modelos de regress

4. Método para determinação de carboidratos empregado na triagem de adulterações em café
The objective in this work was to validate a chromatography method for the determination of total carbohydrates in soluble coffee, using a HPLC-UV-VIS with postcolumn derivatization system, in order to verify adulterant additions. The validated method was accurate and robust. Adulteration could be observed by increasing xylose and glucose levels in samples w

5. Evaluation of the initial development of conilon coffee clones (Coffea canephora).
The Vitória Incaper 8142? variety of conilon coffee (Coffea canephora), presents superior productivity in relation to the others released so far. It consists of thirteen elite clones, whose cultivation is performed in lines. This work aimed to quantify the initial development of the clones which compose ?Vitória Incaper 8142? variety. The experiment was co

7. Estudos para determinação das melhores formulações de blends de cafe arabica (C. arabica) com cafe robusta (C. canephora Conilon) para uso no setor de cafes torrados e moido e de cafes expresso. / Study for determination of the best blends formularizations of arabian (C.arabica) with robust coffee(C. canephora Conilon) for use in the sector of roast and worn coffees and coffees espresso.
The main objective of this thesis was to study various blends of arabica and robusta coffees, prepared both by filtration and the espresso technique, by carrying out sensory evaluations with consumers. Initially, for each coffee studied, the most adequate degree of roast was determined using a sensory evaluation by experts and by a panel trained for Quantita

8. Modelagem e otimização do processo de liofilização : aplicação para leite desnatado e cafe soluve
Freeze drying is a separation process based on the sublimation phenomenon. This process has the following advantages compared to the conventional drying process: the material structure is maintained, moisture is removed at low temperature (reduced transport rates), product stability during storage is increased, the fast transition from moisturized product to

9. The TIME FOR COFFEE Gene Maintains the Amplitude and Timing of Arabidopsis Circadian ClocksW⃞
Plants synchronize developmental and metabolic processes with the earth's 24-h rotation through the integration of circadian rhythms and responses to light. We characterize the time for coffee (tic) mutant that disrupts circadian gating, photoperiodism, and multiple circadian rhythms, with differential effects among rhythms. TIC is distinct in physiological
