1. Chlorophyll content in beet cv. Early Wonder under nitrogen fertilization
ABSTRACT This study aimed to evaluate the effects of doses of nitrogen fertilizer in association with types of basal dressing fertilizers on the physiological characteristics of beet cultivar Early Wonder in a protected environment. The experiment was conducted in safe environment at the Federal University of Campina Grande, using a randomized block design

2. Conservation of Vriesea flammea L.B.Sm., an endemic Brazilian bromeliad: effects of nutrients and carbon source on plant development
Resumo Bromeliaceae é restrita à região neotropical, com alto grau de endemismo, que contribui para o aumento da biodiversidade, devido às características morfológicas dos indivíduos. Objetivando desenvolver uma tecnologia in vitro de conservação para obtenção de plantas com vistas à reintrodução, sementes de Vriesea flammea L.B.Sm. foram colet

3. Novel Food Supplements Formulated With S pirulina To Meet Athletes’ Needs
ABSTRACT The food, training, and health are crucial for a good performance in sports. Intense physical activity takes the athlete to maintain a very unstable balance between energy demand and consumption of nutrients. Spirulina microalga has a nutritional profile that renders it an ideal food supplement, because has high protein content, also contains vitami

5. Omission and Resupply of Nitrogen Affect Physiological and Enzymatic Activities and the Gene Expression of Eucalypt Clones
ABSTRACT: The mineral nutrient uptake of plants in the field occurs in pulses, due to variations in the substance concentrations at the root surface. The fluctuations in nutrient supply probably induce changes in the plant, which are to date unknown for Eucalyptus. This study evaluated these changes in plant growth, nutritional status, photosynthesis, and ge

6. Thermal Transformation and Characterization of Synthetic Al-Substituted Maghemites (γ-Fe2-xAlxO3)
ABSTRACT Burning is a common practice in tropical areas and related changes in mineralogy might affect the chemical and physical behavior of soils. Maghemite is a common iron oxide in soils formed from basic rocks in tropical regions. This mineral and hematite are the main pigments in these soils and exhibit high magnetization stemming from the precursor mag

7. Raman spectroscopy applied to the study of pigments in cultural goods: I - rupestrian paintings / Espectroscopia Raman aplicada ao estudo de pigmentos em bens culturais: I - pinturas rupestres
Neste estudo amostras coletadas de pinturas rupestres foram analisadas para identificação do material utilizado; análises da sua interação e de processos eventuais de degradação, além de atribuições quanto à sua origem, foram também feitas através da espectroscopia Raman. Pigmentos encontrados em pinturas rupestres em Minas Gerais foram identifi

8. Feijão-de-porco [Cnavalia ensiformis (L.) D.C.] cultivado com diferentes fontes de nitrogenio : fixação de N2, fotossintese e crescimento
Several reports point to a negative effect of mineral N on the fonnation and activity of root nodules in legumes that fix the N2 by simbiotic association with rizobia. However, there are few studies establishing a relation between aspects ofthe photosynthesis and the source of N. In this study, an investigation was carried out to verify the influence of the

9. Pigmentos minerais "in natura" e sua aplicação nas artes plasticas no Brasil : um recorte
Natural mineral pigments, constituted mainly by clay minerais, were collected and used by the author in his artistical work. They were studied and their mineralogical and chemical composition was charaterized. The geographicallocation of the collection of the pigments is described. A relate of the historical use of natural mineral pigments is mode as well as
