Abstract: the aster ericoides is a cut flower crop recently introduced into brazil. it has great production potential and acceptation by consumer market but exist little information about fertilization management, essential to its development and quality. in this work we evaluated the nitrogen and potassium fertilization on dry matter yield and nutrient absorption by aster ericoides (white master) growing in a typic hapludox soil under greenhouse conditions. the experiment was set up in a completely randomized design factorial scheme (4 x 4) with 4 rates of n (0; 50; 75 and 100 kg ha-1 n), 4 rates of k (0; 52; 78; 104 kg ha-1 k2o) and 4 replicates at second cycle of culture. the population was maintained at 400,000 plants per hectare. after 105 days, ten stems of each plot were harvested. the stem and leaf dry matter production, number of flowers in each stem and number of principal lateral shoots in each stem were not influenced by treatments. the rate of 46 kg ha-1 of n resulted in maximum flower dry matter production (19.40 g plant-1) and potassium fertilization did not influence the evaluated characteristics. these results showed how necessary it is to be careful with n and k fertilization in this type of soil, to avoid reduced flower dry matter production. more studies about nitrogen and potassium fertilization should be done to define adequate recommendations for aster ericoides planting under tropical conditions.

Abstract: the hollow stem disorder is a common problem in cauliflower, resulting in similar symptom to b deficiency. its occurrence is associated, specially to nitrogen and boron rates. there is few information about this subject in brazil. the experiment was carried out from march to june/2006 in a randomized complete block design with 4 replications. the objective was to evaluate rates of nitrogen (100, 150, 200 and 250 kg ha-1) and b aplication (0 and 3 kg ha-1) on yield and hollow stem disorder of the cauliflower ?júlia? cultivated in kandiustalf at tietê region, s?o paulo state, brazil. the curd diameter was not influenced by treatments and corresponding mean value was 17.74 cm. nitrogen levels increased mean weight, yield and n content of curds. fertilization increased boron contents in curds, commercial yield and reduced hollow stem disorder. there was a negative correlationship between b concentration at curds and hollow stem disorder incidence. therefore, to reduce this physiological disorder the boron fertilization is required when cauliflower is grown even in soil with average b level.

Movimento , 2003,
Abstract: Las pruebas que componen el llamado rodeo completo en Brasil fueron reconocidas como actividades deportivas en el 2001 y sus practicantes fueron considerados deportistas profesionales. El movimiento por la creación de una legislacion nacional respecto al caracter deportivo de los rodeos empezo en los albores de los a os noventa. En aquella epoca, los rodeos ya eran megaeventos juntando actividades de ocio y competiciones en las arenas de las festas de pe o en muchas ciudades del interior brasile o. Este articulo intenta una descripción y un analisis del proceso de reconocimiento oficial de los rodeos y de la creacion de reglas para cada una de las modalidades de este nuevo deporte.

Abstract: This study aimed to investigate the association between the stress levels of parents of children with cerebral palsy and the degree of functional impairment of their children, as well as to explore socio-demographic variables that may potentiate the effects of the motor impairment degree generating high or low/standard stress levels in 92 parents of children with cerebral palsy treated at a federal public hospital of reference in the state of Pará. The instruments used were the Socio-demographic Inventory (ISD), the Gross Motor Function Classification System (GMFCS) and the Parenting Stress Index-short form (PSI/SF). Analyses were performed using SPSS version 20.0. The results showed a greater number of stressed parents in the Difficult Child subscale and a significant relation between the children classified with severe motor impairment and the manifestation of parenting stress. This research showed an approximate age range of children with cerebral palsy in both stressed and little stressed parent groups, but the presence of younger stressed parents in the group was observed. On the other hand, in the group of little stressed parents, a significant aspect found was the prolonged time of union of thecouple at the time of birth of the child with cerebral palsy. The findings of this study intend to contribute to the increase of research about the relation between stress in parents of children with cerebral palsy and the motor function of their children, a theme poorly addressed in national and international research.

Abstract: Efficient honey production requires knowledge about the behavior of the workers and the parameters that influence the strength of the colony. In this study, the objective was to analyze the interaction between the foraging behavior of worker honeybees and pollen storage levels in Africanized honeybees colonies. Colonies with low pollen storage increased pollen intake rates, but this value was 15% lower than colonies with high pollen storage, demonstrating a direct relationship between the pollen storage levels and foraging activity. The difference in pollen intake rates varied according to the number of foraging honeybees and pollen load collected by each individual. Under both high and low pollen storage, colonies returned pollen storage to initial level within 16 days, suggesting that honeybees regulate pollen storage levels around a homeostatic set point. Relationship between pollen storage levels and colony brood production was also found, indicating how alterations in the behavior of each individual can affect the strength of the colony.
