2. Design, development, and implementation of 3D-printed polylactic acid centrifuge rotors for laboratory-scale applications
In this work, self-made laboratory centrifuge equipment was developed for the separation of suspensions and immiscible liquids. This centrifuge was based on the Arduino microcontroller and fabricated from simple and recycled mechanical and electronic parts, spending an inexpensive budget suitably. The centrifuge frame and rotors were manufactured of Polylact

5. Dynamic Arrays Based on Magnetically Controlled Particles: Synthesis and Application
Growth mechanisms of dynamic granular arrays based on magnetically controlled particles are presented. Method of the external rotating magnetic field (ERMF), based on a dipole interaction of magnetic spherical Fe3O4 particles in highly ordered volume arrays is proposed and a design for its practical implementation is developed. The magnetic assembly can resu

6. A pH-responsive drug delivery matrix from an interpolyelectrolyte complex: preparation and pharmacotechnical properties
ABSTRACT Interpolyelectrolyte complexes, which constitute a type of polymeric material obtained through the self-assembly of oppositely charged polymers, exhibit interesting properties for use in the design of smart matrices for drug delivery. In the present study, a stoichiometric interpolyelectrolyte complex (SIPEC) composed of Eudragit E® and Eudragit®

8. Leaders or Loners? How Do the BRICS Countries and their Regions Vote in the UN General Assembly
The so-called emerging powers, including the BRICS nations (Brazil, Russia, India, China and South Africa), typically present themselves as natural leaders of their regions. Although physical size confers them the status of regional powers, their role as leaders depends on the consensual acceptance of their would-be followers. Can it be affirmed then that th

10. Emigración y representación especial: Evidencia de los Ecuatorianos Residentes en el exterior
Abstract A vast majority of countries worldwide have granted citizenship rights to their emigrants, in particular external voting and dual citizenship. However, there is a relatively new migrant political transnational practice that home-countries are gradually legislating and implementing: special representation, i.e. emigrant political representation in ho

12. Fins Module Conception of the Microsatellite Launch Vehicle Based on Design for Manufacture and Assembly Method
ABSTRACT: This paper presents the application of the Design for Manufacture and Assembly method (DFMA) during the conception of a space product. This approach enables to capture manufacture and assembly requirements in early phases of development. DFMA guides the manufacture processes and materials that rule the Fins Module interface to the Microsatellite La
