1. A Comparative Survey on Flight Software Frameworks for ‘New Space’ Nanosatellite Missions
ABSTRACT: Nanosatellite missions are becoming increasingly popular nowadays, especially because of their reduced cost. Therefore, many organizations are entering the space sector due to the paradigm shift caused by nanosatellites. Despite the reduced size of these spacecrafts, their Flight Software (FSW) complexity is not proportional to the satellite volume

2. Physical methods for topical skin drug delivery: concepts and applications
Topical drug delivery is an interesting approach to treat skin diseases and to avoid pain and low patient compliance in cases where a systemic delivery is required. However, the stratum corneum, which is the outermost skin layer, strongly protects the body from the entrance of substances, especially those hydrophilic. In this context, different physical meth

3. THEORETICAL RESEARCH ON THE MULTI-CHANNEL REACTION MECHANISM AND KINETICS OF HNCS WITH OH-
We presented a theoretical study on the detailed reaction mechanism and kinetics of the HNCS molecule with the OH-. The barrierless minimum energy path and the most favorable entrance channel have been determined by study the thermodynamic and kinetic characters of the channel with low energy barrier. The B3LYP/6-311++G** method was employed for all the geom

4. A concretização do direito ao trabalho e as pessoas com deficiência intelectual: uma análise a partir da situação da cidade de Osasco/SP / The concretization of the right to labor and the people with Intellectual disability: an analysis focused on the city of Osasco/SP
The aim of this research is to demonstrate that the right to labor (as a social right, according to the Federal Constitution of 1988) is not a reality to all Brazilian citizens, especially to people to with disabilities, therefore creating a barrier to the development of Human Rights. The entrance in the capitalist business world depends solely on the indivi

5. A CADEIA DE PRODUÇÃO DO MEL NO RIO GRANDE DO SUL: A ORGANIZAÇÃO E A GOVERNANÇA NAS TRANSAÇÕES DOS APICULTORES ASSOCIADOS À APISMAR / HONEY PRODUCTION CHAIN IN RIO GRANDE DO SUL: THE ORGANIZATION AND GOVERNANCE IN THE TRANSACTIONS OF APISMAR BEEKEEPERS
This study aims to determine the organization and governance in the transactions of APISMAR beekeepers and describe the honey production chain in Rio Grande do Sul. It is used as a theoretical framework the concept of agroindustrial production chain, the structure-conduct-performance paradigm (SCP), and the theory of transaction cost economics (TCE). The res

6. Formação e desenvolvimento das redes de cervejarias artesanais no Vale do Itajaí
The objective of this study is to demonstrate how the artisanal breweries were formed and developed in Vale do Itajaí, by having the city of Blumenau, more specifically, Oktoberfest as their boosters. It is known that the city of Blumenau has already had initiatives in the field and breweries with technology brought by German immigrants, which might have be

7. Interação da matéria de vórtices com estruturas de defeitos : detecção das primeiras penetrações
This thesis results from a systematic study of the interactions between penetrated vortices and pinning centers carried out on structured superconductors films of YBCO, Nb and Pb. A regular array of pinning centers (antidots, ADs) was inserted in those samples by mechanical indentations (in YBCO and Nb films), and by a lithographic processes (Pb). The struct

8. AdequaÃÃo da metodologia do teste de tetrazÃlio para avaliaÃÃo da viabilidade de sementes de cafà no armazenamento / Adaptation of the methodology of the tetrazolium test to assess the viability of coffee seeds during storage
Germination of coffee seeds occurs in a slow and uneven way, making it difficult to obtain results of quality evaluation of lots in time for the propagation. One of the factors that delay germination is the presence of parchment that acts as a physical barrier to water and gases entrance. The tetrazolium test is an alternative for fast evaluation of seeds vi

9. InserÃÃo da Rede Globo no mercado de televisÃo pernambucano
The purpose of this work is to analyse the Rede GloboÂs strategies to include itself in the state of PernambucoÂs television market. A historical study was done of the broadcasting station and of Brazil and PernambucoÂs television market, in which it is localized, as a local network and broadcasting station, respectively. The hypothesis is that the Rede G

10. Análise da concorrência no setor de supermercados de Salvador na perspectiva de uma política antitruste
This work represents a structural analysis of the supermarket sector in Salvador, considering theoretical, legal and market aspects, regarding rivalry conditions, competition patterns, market concentration, entry barrier levels and a survey of defensive techniques to competition used by regulatory organs in Brazil, in an attempt to understand the reasons for

11. Propriedades de equilÃbrio e de transporte da matÃria de vÃrtices em nanoestruturas supercondutoras
In the present thesis, we study theoretically the equilibrium properties and dynamics of the vortex matter in two classes of nanostructured superconductors: (i) mesoscopic samples, with dimensions comparable with the penetration depth; and (ii) films with periodic array of artificial traps. In both cases, the vortex lattice symmetry is strongly dependent on

12. ESTUDO DA PERMEABILIDADE À ÁGUA NA CAMADA DE COBRIMENTO DE PROTÓTIPOS DE CONCRETOS COM ALTOS TEORES DE CINZA VOLANTE
The civil construction industry is, as times goes by, more related with echo-social efficiency and society and the concrete, most used building material, has its use associated with concerns on the durability and the performance of the constructions, looking for the optimization of the natural resources. The durability esteem of a concrete is the function of
