Piperaceae species are of great importance for the Brazilian flora, due to their medicinal potential. However, work with these species is still very scarce, especially considering the divergence in the germination process. Given the above, the objective of this work was to evaluate the germinative development of the seeds of Piper marginatum, Piper umbellatum, Piper hispidum, Piper aduncumand Piper mollicomum maintained under different temperature levels.

L’alphabétisation constitue un facteur essentiel dans l’exécution des politiques éducatives. Elle permet aux bénéficiaires ciblés de se doter des compétences fonctionnelles nécessaires en vue de contribuer pleinement au développement économique et social. Dans le pilotage des programmes d’alphabétisation en Côte d’Ivoire, la fonctionnalité des contenus, l’efficacité de la stratégie et la qualité des enseignements participent à la mise en évidence de la rentabilité des résultats et à l’acquisition des niveaux d’alphabétisme par les apprenants.

Carbon emissions from land use change are insufficiently addressed in developing countries. While estimation of carbon stocks within different land management and cropping systems are an important element in design of productive land use systems that protect or sequester carbon. The aim of this study was firstly to assess SOC and N stocks and secondly to assess tree density, both related to different land use in savanna woodland. Results show that Savanna woodland soil organic carbon stocks (19.61±0.9 tC ha-1) was greater than cropland (15.07±0.84tC ha-1) and fallows (11.13±1.1 tC ha-1).

O Acidente Vascular Cerebral é definido como um distúrbio focal ou global da função cerebral, que evolui rapidamente e dura mais de 24 horas, provocando sequelas motoras, sensitivas e cognitivas. Constitui a razão mais comum de incapacidade neurológica no mundo. AEstimulação Transcraniana por Corrente Contínua é uma técnica que atualmente ressurgiu como um recurso promissor para modulação da atividade cerebral de modo não invasivo, representando uma potencial ferramenta para o tratamento de transtornos neurológicos como o Acidente vascular cerebral.

A Gestão do Conhecimento (GC) é um campo do conhecimento que vem alargando suas aplicações no Brasil. A conversão do conhecimento tácito em conhecimento explícito e acessível, tem-se constituído um dos principais ativos das organizações, o que não é diferente com as organizações de Ensino Superior. A taxonomia como ferramenta estratégica da GC atua diretamente no processo de recuperação e organização da informação, auxiliando na sistematização e identificação dos processos e nas rotinas das organizações.

O presente trabalho objetivou analisar a atuação do Psicólogo no processo de Mobilidade Social (Transformação Social) dos usuários do Sistema Único de Assistência Social (SUAS). Para a obtenção de dados foram realizadas entrevistas semiestruturadas e questionários sociodemográficos, respondidos por 4 profissionais de Psicologia que atuam nos Centros de Referência da Assistência Social (CRAS).

The research features how geophysical methods are used to optimize solutions for different types of environmental problems. To verify the use frequency of these methods today, a wide survey was carried out in recent articles from the scientific journals of the Geophysical Society of three countries: Journal of Environmental & Engeneering Geophysics (JEEG) and Near Surface Geophysics (NSG) and Revista Brasileira de Geofísica (RBGF).

This research was characterized as a quantitative cross-sectional descriptive. During the motor development process, a series of physical and mechanical changes occur, where the factors of physical growth, maturation, development of physical fitness, physical activity, age and experience are interrelated. The general objective of this study was to study the different effects of physical fitness on the motor performance of adolescents aged 13 to 16 years in the city of Itaituba / Pará.

For a solar farm to adequately meet the energy needs of electrically isolated Brazilian systems in the North Region, at prices compatible with local income, subsidies are necessary, whose establishment must correspond to a consensus of Brazilian society through its representative bodies.

It has been shown that the proposed solid state synthesis technique has advantages over the most commonly used coprecipitation methodology, by avoiding the undesirable polymerization of the VO43- ion in an aqueous medium. The formation of strontium vanadateapatite occurs at 600 ° C as a monophasic sample. According to X-ray diffraction, the substitution of strontium for calcium in the structure of apatite vanadate containing gallium was achieved. The intercalated gallium atoms produce no structural distortion or alteration of the hydroxyapatite matrix.
