1. Microstrip 3-Bit Fractal-based Phase Shifter
Abstract This paper presents the implementation of a 3-bit microstrip fractal-based phase shifter operating in the 430 MHz to 470 MHz frequency range. The fractal structure is used to confine different delay line lengths in the same area due to the space-filling properties of the used Hilbert fractal curve. The proposed design has three bits corresponding to

2. Fare etnografia delle migrazioni ai tempi della pandemia. Note di ricerca dal confine franco-italiano nel primo lockdown
Abstract The Covid-19 emergency and the legislation issued by European governments have a deep impact on the contemporary migratory dimension, as well on the forms and ways of studying it. This contribution, the result of a “quarantine research”, is contextualized in the first phase of the outbreak of the pandemic in Italy and France (late February - ear

3. Subverting the Ideal of Womanhood: Mary Lavin’s “Sarah” and Female Agency
Abstract: Women’s living conditions in the Republic of Ireland in the 1940s were strongly conditioned by Catholic beliefs since the Church still held great influence at institutional levels and maintained close relations to leading politicians. The 1937 Constitution was the clearest proof of such relation, and tried to confine women’s role merely to the

5. LAMPEDUSA TRA PRODUZIONE E RAPPRESENTAZIONE DEL CONFINE
Abstract Why is Lampedusa a synonym for the Euro-African border? Borders are social products, and turning a place into a border, or transforming the symbolic and practical role of a border place, is always the result of specific social acts. Starting from this assumption, the paper analyses the most important acts that increased Lampedusa’s “borderness�

7. Controle e interação de fonons e fotons em fibras opticas de cristal fotonico / Control and interaction of phonons and photons in photonic crystal fibers
Techniques that may allow control and tight confinement of photons and phonons in photonic crystal fibers (PCFs) are investigated in this thesis. By means of robust numerical methods to solve Maxwell equations, a new kind of PCF with a tubular core is proposed. Simulations and experimental results show that such structure is able to confine light tighly insi

10. Avaliação do comportamento fisico-quimico-mecanico de misturas cimento-cinza-casca de arroz por meio de corpos-de-prova cilindricos e placas prensadas
The recycling is an effective tool to minimize environmental impact that is caused by human civilization. The utilization agricultural residual for rural construction is an efficient way for retain or reduce carbon emission to the atmosphere. However, the present-day techno logy is not enough to be a satisfactory level. A part of the residue is not consumed,

11. Psychological evaluation: the social and family perspective on complementary strategies for the clinic practice of children / Avaliação psicológica: a perspectiva sócio-familiar nas estratégias complementares à prática clínica infantil
The psychological evaluation of the child stresses the importance of studying the familiar dynamics as an indispensable procedure, though it does not confine in itself the whole universe of relationships linked to the child. Studies on psychological evaluation, particularly the ones based on a comprehensive model, point to the need of considering the integra

12. Sustaibability in a structure of integrated systems / Sustentabilidade em uma estrutura de sistemas integrados
Decisions related to the sustainable development involve the following: what to sustain and how to sustain. In general, these decisions are based on assumptions about the permanence of certain characteristics of the systems involved, be them natural or socio-economic. Moreover, these decisions can be only of ethical character or may involve formulations that
