14. EVALUATION OF THE FLOCCULATION EFFICIENCY OF Chlorella vulgaris MEDIATED BY Moringa oleifera SEED UNDER DIFFERENT FORMS: FLOUR, SEED CAKE AND EXTRACTS OF FLOUR AND CAKE
Abstract Flocculation as a pre-separation method can help make production of biodiesel from microalgae economically feasible. In a previous study, Moringa oleifera seed flour (1 g.L-1) was shown to be a very efficient flocculant for Chlorella vulgaris, a microalga with high potential for biodiesel production. In this study, several aspects of C vulgaris floc

15. Production system and harvesting stage influence on nitrate content and quality of butterhead lettuce
Leafy vegetables such as lettuce grown under different production systems may accumulate different concentrations of nitrate which may reach to the levels potentially toxic to humans. Moreover, nitrate accumulation varies in various plant parts and physiological age of the plant. Therefore, to determine the effect of production system and harvesting stage on

16. Physicochemical and antioxidant properties of kiwifruit as a function of cultivar and fruit harvested month
The present study was carried out to find the effect of fruit harvesting stage (October, November and December) on the physicochemical and antioxidant properties in five kiwi cultivars (Abbot, Bruno, Allison, Hayward, Monty). Results showed that soluble solid content (SSC) and pH increased while ascorbic acid (Vit C), titrated acidity (TAD) and SSC/TAD decre

17. Physiological Changes in the Seeds of Jatropha curcas L. at Different Stages of Fruit Maturity
The objective of present study was to determine appropriate fruit harvesting stage for Jatropha curcas L. for getting seeds with good oil content and better germination. The seeds separated from the fruits harvested at yellow capsule stage (C2) showed maximum germination efficiency, both under laboratory and nursery conditions whereas seeds separated from th

18. Mudanças nos uso e preços de terras do Estado de São Paulo - período de 1995 a 2010 / Changes in land use and farmland prices in São Paulo State: from 1995 to 2010
This work has examined major changes in land occupation in different regions of São Paulo State to determine major vectors of the observed changes in farmland prices, between 1995 and 2010. This period encompasses both the period of retraction and deregulation of the sugarcane sector, after the extinction of Proálcool program, and the new stage of investme

19. AvaliaÃÃo da PolÃtica Nacional de Transplantes no CearÃ: AtuaÃÃo da Central Estadual e das ComiÃÃes Intra-Hospitalares / Evaluation of the National Transplant in CearÃ: Central Role of State and Intra-Hospital Commissions
In recent decades, the transplants have had a profound impact on the care of end-stage patients with several kinds of diseases. In Brazil, public policies regarding people who need transplants require thorough assessments. This research aimed to evaluate the performance of the Organ Notification, Harvesting and Distribution Center of the State of Cearà (CNC

20. Brazilian experience using high dose sequential chemotherapy followed by autologous hematopoietic stem cell transplantation for malignant lymphomas
OBJECTIVE: To evaluate the use of high-dose sequential chemotherapy in a Brazilian population. METHODS: High-dose cyclophosphamide followed by autologous hematopoietic stem cell transplantation is an effective and feasible therapy for refractory/relapsed lymphomas; this regimen has never before been evaluated in a Brazilian population. All patients (106 with

21. Changes in seed quality during fruit maturation of sweet pepper
Studies regarding seed maturation are important to determine the ideal fruit development stage for harvesting in order to obtain high-quality seeds. Changes in sweet pepper (Capsicum annuum L.) seed quality were monitored during seed development in order to identify the stage of maximum quality of the seeds and the optimum harvest date. Fruits harvested from

22. Induction of insect plant resistance to the spittlebug Mahanarva fimbriolata Stål (Hemiptera: Cercopidae) in sugarcane by silicon application
Changes in the agroecosystem with the increase of green cane harvesting in Brazil affected the insect populations associated to this crop, and secondary pests like the spittlebug Mahanarva fimbriolata Stål, became much more important. Many studies have demonstrated the active role played by silicon in plant defense against herbivory. The objective of this s

23. Discriminação entre estádios de maturação e tipos de processamento de pós-colheita de cafés arábica por microextração em fase sólida e análise de componentes principais
A fruit chemical composition reflects its maturation stage. For coffee, it is also the reflex of the post-harvesting processing type, dry, semi-wet and wet. The object of this work was to verify if headspace solid phase microextraction coupled to gas chromatography (HS-SPME-GC) could be used to discriminate between samples harvested in different maturation s

24. Relacao entre a idade do cacho de banana 'prata' a colheita e a qualidade dos frutos apos a colheita.
Metodos de colheita estabelecidos para bananas, como a verificacao do diametro ou desaparecimento da angulosidade dos frutos, nao sao adequados, quando se trata de banana 'Prata' (Musa AAB), visto que esta cultivar e de porte alto e apresenta frutos irregulares em tamanho e forma. O objetivo deste trabalho foi verificar a epoca ideal de colheita, por meio da
