Trocas gasosas, caracterização citogenética e vigor de sementes dos gêneros Opu...
Silva, Ronimeire Torres daWidely cultivated in the Northeast Region of Brazil, forage palm belongs to the family Cactaceae, with Opuntia and Nopalea as the main genera. Studies involving gas exchange, chromosome variation and physiological quality of seeds belonging to different species in this family are still incipient. The objectives of this study were to evaluate the gas exchange, to correlate the ploidy levels with phenotypic chara...
Simulação numérica de fraturamento hidráulico em um reservatório arenítico da B...
Silva, Gracimário Bezerra daHydraulic fracturing consists of a technique capable of stimulating oil wells that have suffered a decline in production over time, as well as allowing the production of reservoirs that have low permeability, through the creation of a network of channels in the rock, promoting the connection between the pores in the rocky environment. The hydraulically induced fracture in the formation is generally created and ...
Tvs legislativas e sua relação com a interatividade, produção de conteúdo, desi...
Santos, Rodolpho Raphael de OliveiraWith the reconfiguration of the technology and the transition from an era to an era where converging the connection is done, it has been constant in individualization of content the center point of a powerful debate about audience and content production reflecting the interactivity in TVs in Brazil, especially the Legislative TVs where the focus of the research will be directed to the experiences of the context...
Dinâmica estocástica de sistemas biológicos: caos e o efeito do predador de topo
Souza Filho, Carlos Alberto deTo understand how different species interact and the mechanisms responsible for maintaining biodiversity observed in nature is a still open issue in ecology. Several simplified models have been proposed and extensively studied in the last few decades. As an example we can mention the acyclic predator-prey model of Lotka-Volterra, used to study the transitive competing relationship (hierarchical) between two or mo...
Hörmander’s theorem for stochastic evolution equations driven by fractional Bro...
Nascimento, Jorge Alexandre Cardoso doIn this thesis, we prove the Hörmander’s theorem for a stochastic evolution equation driven by a trace-class fractional Brownian motion with Hurst exponent 1 2 < H < 1 and an analytical semigroup {S(t);t ≥ 0} on a given separable Hilbert space E. In contrast to the classical finite-dimensional case, the Jacobian operator in typical parabolicstochasticPDEsisnotinvertiblewhichcausesaseveredifficultyinexpressing the ...
Viabilidade técnica do biodiesel metílico do óleo de duas variedades de Cartham...
Medeiros, Petruccio TenórioThe safflower (Carthamus tinctorius L.) is an energetic oilseed with high oil contents ranging between 35 to 48% and has high adaptability to dry and arid regions, may be a good alternative source for biofuel production in the Brazilian semiarid. The methyl biodiesel was obtained via transesterification reaction of the oil from two safflower varieties: one with 76,87% of oleic acid (C18:1) and another with 60,1...
Problematizando a temática elementos metálicos em aulas de ciências (química) n...
Monteiro Júnior, José Maurício de AlbuquerqueThe pedagogical moments technique has been used as a possibility of knowledge organization in science classes, and has emerged as a proposal to teach this discipline aiming at scientific literacy. This research was carried out in a private elementary and middle school, located in the neighborhood of Bessa, in the city of João Pessoa, in the state of Paraíba, whose sample consisted of 37 students from the 8th gr...
Avaliação da mobilidade urbana e das áreas verdes do município de João Pessoa, ...
Fernandes, Hélder FormigaThe objective of this research was to evaluate the Urban Mobility and the Green Areas of the Municipality of João Pessoa, in the perspective of the development of a sustainable city. The theoretical basis of the research was elaborated with the aid of the norm ABNT NBR ISO 37.120:2017, which gives the necessary parameters to evaluate the sustainable development of communities. Periodic visits were made to the S...
A gestão participativa em áreas sobrepostas de unidade de conservação e terra i...
Costa, Ivys Medeiros daSocial participation in the planning and execution of indigenous territorial and environmental management is essential for participatory management in overlapping areas: territories that are Conservation Unit (CU) and also Indigenous Land (IL), simultaneously. However, although this participation is established in the legal norms in force, it is still a challenge due to conflicting and divergent interests of th...
Desenvolvimento de filmes e recobrimentos multifuncionais a partir de fontes de...
Guimarães, George Henrique CamêloThe use of biodegradable starch based films and recoveries goes beyond the conservation of plant products, as films and recoveries alter the physiology of these plant products. Given this, the studies should be directed to an evaluation of the physiological changes of the recovered or packaged products and deepen a discussion about several starch sources that can be used and what are the technological implicati...
