Microalgae Lipid and Biodiesel Production: A Brazilian Challenge  [PDF]
Carolina T. Miranda, Roberta F. Pinto, Daniel V. N. de Lima, Carolina V. Viegas, Simone M. da Costa, Sandra M. F. O. Azevedo
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.615254
Abstract: Global increases in atmospheric CO2 and climate change are drawing considerable attention to identify sources of energy with lower environmental impact than those currently in use. Biodiesel production from microalgae lipids can, in the future, occupy a prominent place in energy generation because it represents a sustainable alternative to petroleum-based fuels. Several species of microalgae produce large amounts of lipids per biomass unit. Triacylglycerol is the fatty acid used for biodiesel production and the main source of energy reserves in microalgae. The current literature indicates that nutrient limitations can lead to triacylglycerol accumulation in different species of microalgae. Further efforts in microalgae screening for biodiesel production are needed to discover a native microalgae that will be feasible for biodiesel production in terms of biomass productivity and oil. This revision focuses in the biotechnological potential and viability of biodiesel production from microalgae. Brazil is located in a tropical region with high light rates and adequate average temperatures for the growth of microalgae. The wide availability of bodies of water and land will allow the country to produce renewable energy from microalgae.

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.

Memórias do Instituto Oswaldo Cruz , 2007, DOI: 10.1590/S0074-02762007005000016
Abstract: the aim of the present study, in view of the widespread geographical distribution of lutzomyia (nyssomyia) whitmani s.l. in brazil, in close association with the regions of transmission of leishmania (viannia) braziliensis and l. (v.) shawi, is to investigate the distribution of this sand fly species and american cutaneous leishmaniasis (acl) in relationship to vegetation and landscape ecology throughout brazil. thematic maps were elaborated by the mapinfo programme, giving information on the spatial distribution of l. whitmani s.l., in accordance with types of vegetation and foci of acl. with regards to the known areas of transmission of acl in brazil, it is notable that l. (n.) whitmani s.l. occurs in most of them, where it has been implicated as a possible vector of l. (v.) braziliensis. the presence of l. whitmani s.l. has been registered in 26 states, the one exception being santa catarina; in some states such as roraima, acre, tocantins, and mato grosso do sul this sand fly species has been recorded in a large number of municipalities. l. whitmani s.l. has been found in association with a variety of vegetation types, including the amazonian forest, savanna ("campos cerrados"), and northeastern savanna ("caatingas nordestinas" or "savana estépica").

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.

Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.81004
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.
