The influence of additives on the current carrying capacity of bulk YBa2Cu3OX

We studied the influence of using different powders and several additives on the shaping process and critical current density of sintered bulk YBa2Cu3OX. It was found that all additives used facilitated the shaping process. Silver and most organic additives influenced the critical current density only little, Zinc reduced it to zero, but an ethylenebisstearoylamide compound doubled the critical current density as compared to samples without additives

FACULTY IMPROVEMENT IN VENEZUELAN UNIVERSITIES: A PROPOSAL FOR THE DESIGN AND IMPLEMENTATION OF A DEVELOPMENT PROGRAM

Las universidades venezolanas se desenvuelven en un mundo globalizado y cambiante al cual le intentan dar respuesta instrumentando acciones relacionadas al mejoramiento de los profesores. Para acometer esa tarea, se propone un modelo de formación profesoral fundamentado en la satisfacción de necesidades individuales, institucionales y contextuales. Se describen las etapas de diseño e instrumentación del programa de formación, concluyendo con una reflexión sobre la importancia de atender apropiadamente lo relativo al desarrollo de los profesores universitarios y al compromiso que los gerentes educativos deben adquirir con el uso eficiente de los recursos y la gestión de instituciones que respondan cabalmente a lo que la sociedad requiere.Venezuelan universities develop in a changing and globalized word. They must fulfill what has been established in governmental policies regarding faculty development. This paper proposes a model for faculty development based on individual and societal needs.Design and implementation stages of the program are described in detail and followed by discussion of the importance of enough government support, university leaders’ commitment to efficient administration of funds and the implementation of programs that produced the changes needed by society
