2. Technical and economic viability of the installation of a hybrid solar-wind generation system in a Brazilian industry
Abstract The demand for electricity is growing worldwide. At the same time, the non-renewable natural resources that account for a large proportion of the global energy matrix are rapidly depleting, which will pose a major challenge in the near future. Therefore, micro-grid models that use renewable energy sources, such as solar and wind, are rapidly develo

3. Isolation of quinoline alkaloids from three Choisya species by high-speed countercurrent chromatography and the determination of their antioxidant capacity
Abstract Choisya ternata Kunth, C. ternata var. sundance Kunth and the hybrid Choisya ‘Aztec-Pearl’ are three related species belonging to the Rutaceae family. Ethanol extracts were prepared from the leaves of these three species and evaluated in relation to their antioxidant activity using in vitro and ex vivo models. The ethanol extracts belonging to t

5. Integral transform solution of natural convection in a square cavity with volumetric heat generation
The generalized integral transform technique (GITT) is employed to obtain a hybrid numerical-analytical solution of natural convection in a cavity with volumetric heat generation. The hybrid nature of this approach allows for the establishment of benchmark results in the solution of non-linear partial differential equation systems, including the coupled set

9. Estruturas HÃbridas de Nanotubos de Carbono de Parede Simples e TelÃrio. / Single Wall Carbon Nanotubes and Tellurium Hybrid Structures
In this work we use Raman spectroscopy and electron microscopy to characterize hybrid carbon nanotube single-wall and tellurium nanostructures. Carbon nanotubes are important nanostructures due to their electrical, optical and mechanical properties, which makes them attractive for many applications in nanotechnology. However, for a wide range of applications

10. Produção e caracterização do anticorpo monoclonal aDEC205 acoplado a proteína MSP-1 (19) de Plasmodium chabaudi. / Production and characterization of a monoclonal antibody aDEC205 coupled to MSP-1(19) protein from Plasmodium chabaudi.
Despite the strong activation of the immune system that occurs during infection by Plasmodium, the immunological memory to infection is restricted to patients residing in endemic areas. Thus it is important to the generation of methods to induce an effective immune response against the parasite. In this context, the targeting of antigens to the central cells

11. Development and assessment of an upper limb hybrid system for quadriplegics / Desenvolvimento e avaliação de um protótipo de sistema híbrido para membro superior de tetraplégicos
Generally, individuals with motor impairments in the upper limbs have difficulties performing the movement of objects, which is essential for the execution of activities of daily living. Thus, these individuals do not perform these activities or perform them inefficiently. Toward satisfactory manipulation, reach and grasp movements of objects performed with

12. Dimensionamento ótimo de sistemas híbridos, com geração fotovoltaica e célula a combustível, para atendimento a comunidades isoladas na Amazônia / Optimal design of a hybrid photovoltaic and fuel cell power generation system, to supply isolated communities in the Brazilian Amazon.
The lack of electricity in isolated communities in the Brazilian Amazon has become one of the greatest barriers for the development of the region. Currently, the main technologies that provide electricity to these communities are diesel generators, batteries and dry cells. These non-renewable energy sources may pose serious problems to the environment and hu
