    La Materia y lo Imaginario o de la Danza de Maya en el Vacío por Narvaez Tijerina, Adolfo Benito

    Publicado 2017
    “…El artículo aborda el problema de la investigación sobre lo imaginario cuando se parte de la base de una investigación sobre el universo material. Se traza un panorama de la evolución del concepto de materia en la filosofía y ciencia de occidente, hasta llegar a las concepciones modernas basadas en los descubrimientos de la física contemporánea, se exploran las implicaciones filosóficas de la interpretación de Copenhague, frente a las interpretaciones deterministas de la física de partículas y la posibilidad de niveles de existencia de la materia que poseerían propiedades contra-intuitivas. …”

    Nanostructured titanium dioxide film preparation using inorganic nanoparticles instead of organic precursor materials por Jamali, A., Eghbali, M. H.

    Publicado 2011
    “…Comprehensive study on impact of different factors including temperature, type of surfactants, type of solvents, concentration of surfactants, and concentration of solvents on quality of thin film including band gap, particle size, strength and homogeneity was performed in this work. Material characterization tests including UV-Visible spectroscopy and field emission scanning electron microscopy were carried out to analyse the film characteristics. …”

    Carbon fiber recovery using subcritical and supercritical fluids for chemical recycling of thermoset composite materials por Morales Ibarra, Rodolfo

    Publicado 2014
    “…In this research, benzyl alcohol and water in subcritical and supercritical conditions, with and without addition of tripotassium phosphate (K3PO4) as a decomposition reaction catalyst, were used to recover carbon fibers from composite materials for potential reuse in high performance components; while, in the literature review, the composite materials and their manufacturing processes were revisited, as well as the legal implications of end-of-life composite components, justifying the need for a thermoset composite materials recycling research project. …”

    Hacia un modelo garantista de procedimiento en materia familiar para Bolivia por De la Fuente Jeria, Norma Tatiana

    Publicado 2013
    “…La realidad familiar en el mundo y, concretamente, en Bolivia, tiende a identificar las causas de los conflictos surgidos en los círculos familiares y se encuentran en un círculo cada vez más grande y en muchos casos difíciles de resolver que terminan en una ruptura o desvinculación o desintegración familiar, esto al no poder resolver objetivamente y en su momento, que a veces por este miedo de reconocer su realidad o tener que enfrentar, prefieren no afrontar hasta llegar a un punto en que no existe posibilidad de superar los conflictos a través de medios extrajudiciales o judiciales, que permita evitar la ruptura, desintegración familiar, buscando formas de solucionar, que además no deriven en problemas de mayor magnitud, que en materia familiar si derivan en otros conflictos como en casos penales.…”
