Rivero Díaz,Raúl; Fuentes González,Leonardo;
Revista Cubana de Obstetricia y Ginecolog?-a , 1997,
Abstract: a study of 47 patients who underwent hysterectomy during the puerperal period between may, 1989, and november, 1992, was conducted. it was made an analysis of different variables. the results were compared with the findings of other authors, and it was concluded that the highest percentage of patients that were operated on had never given birth. it was stressed the use of cesarean sections to finish deliveries. sepsis and uterine atony were the fundamental causes of hysterectomy.

Abstract: Se realiza un estudio de 47 pacientes a quienes se les realizó histerectomía en el período puerperal entre mayo de 1989 y noviembre de 1992 y se analizan distintas variables. Estos resultados se comparan con los hallazgos de otros autores, y se concluye que el mayor porcentaje de operadas eran nulíparas, donde se destacó la cesárea como proceder para terminar los partos. La sepsis y la atonía uterina fueron las causas fundamentales de la histerectomía.

Revista Cubana de Ingeniería , 2010, DOI: 10.1234/rci.v1i3.28
Abstract: Diesel engine generator (RM) is one of the most used technologies on distributed generation (DG). The presence of RM, no manner its operation form need an analysis about differents problems: one of them is related with power quality (PQ). First results obained inside one study directed to obtain answers about differents perturbations for the RM presence like shortcircuit and voltage variation on RM termianls and rejected charge are presented in this paper. Entre las tecnologías de mayor difusión que en la actualidad se utilizan dentro de la generación distribuida (GD) están los grupos electrógenos (GE) Los GE en cualquiera de sus formas de explotación, exigen un análisis de los problemas que puedan manifestarse por su presencia; uno de estos problemas está relacionado con la calidad de la energía eléctrica (CEL). El presente trabajo expone los primeros resultados de un estudio que va dirigido a buscar respuestas sobre este tema ante diferentes tipos de perturbaciones que pueden presentarse en la red: Cortocircuito y variación de la tensión en los terminales del GE y la desconexión súbita de la carga (rechazo de carga).

(Ir)retroactividad de las modificaciones a la norma complementaria de una Ley Penal en Blanco
Baldomino Díaz,Raúl A;
Política criminal , 2009, DOI: 10.4067/S0718-33992009000100004
Abstract: the author, starting from the nullum crimen nulla poena sine lege principle, explains the scope of the legality principle for criminal laws in blank, stating that they must contain the main verb of the conduct and its subjective aspect, thus allowing their completion through statutory norms. recognizing legal certainty as the basis for irretroactivity of criminal laws, and proportionality and necessity of punishment as a justification for more benign criminal law retroactivity, shows the underlying retroactive application problems of amending the statutory norm.
(Ir)retroactividad de las modificaciones a la norma complementaria de una Ley Penal en Blanco
Raúl A. Baldomino Díaz
Política criminal , 2009,
Abstract: El autor, a partir del nullum crimen nulla poena sine lege, expone los alcances del principio de legalidad en las leyes penales en blanco, indicando que aquellas deben contener el verbo rector de la conducta y su faz subjetiva, permitiendo su complemento por las normas reglamentarias. Reconociendo a la seguridad jurídica como fundamento de la irretroactividad de la ley penal, y a la proporcionalidad y necesidad de la pena como justificación de la retroactividad de la ley penal más benigna, expone los problemas de aplicación retroactiva que pueden aparecer con la modificación de la norma complementaria.
Extender la interculturalidad a toda la sociedad: reflexiones y propuestas desde el sur argentino
Raúl Díaz,Jorgelina Villarreal
Cuadernos Interculturales , 2009,
Abstract: Preguntas geopolíticas una vez más. La apuesta es difícil dados los retrocesos de las reformas educativas latinoamericanas y en particular la de Argentina. A los indígenas lo de ellos y compensado, a nosotros lo mismo y descompensado. Y dentro del derecho, el reconocimiento de los Pueblos Originarios, formal, en principio. Nos interesa debatir acerca de los problemas que implica la interculturalidad como propuesta basada en la lengua y destinada a indígenas, promoviendo la curricularización de lo propio. Y la necesidad de una concepción extendida de lo intercultural hacia el resto de la sociedad por un lado, y hacia ámbitos como el jurídico, político, económico, social, y cultural, por el otro. Desde nuestra práctica colaborativa con organizaciones indígenas y con otras instituciones sociales, reflexionamos a partir de nuestra inclusión en los debates pedagógicos y políticos contextualizados en el sur argentino.

Abstract: Background: The rapid diagnosis of mycobacterial infections is essential to implement the adequate antimicrobial therapy. This study evaluates the performance of the BacT/ALERT 3D system for isolates and identification of mycobacteria from clinical samples. Methods: 1011 clinical specimens from nonsterile and sterile body sites were studied from August 2010 to December 2012 at the National Reference Laboratory of Tuberculosis, IPK, Cuba. The results obtained were compared with respect to time detection of mycobacteria and contamination rates, and performance indicators of BacT/ALERT 3D were calculated. Results: The time detection of growth (TDG) for Mycobacterium tuberculosis (Mtb) and nontuberculous mycobacteria (NTM) by BacT/ALERT 3D was 16,435 and 10,956, respectively; by LJ the TDG was 33.577 for Mtb and 35.952 for NTM. By culture method used the TDG for LJ was 33,577 and 6.435 by BacT/ALERT 3D, this difference being statistically significant. The overall contamination rate (CR) for BacT/ALERT 3D was 4.6% and 7.8% for LJ. Conclusions: BacT/ALERT 3D were a suitable method for recovering mycobacteria from clinical samples. It demonstrated a shorter time to detection of mycobacteria growth; it was very useful to provide faster treatment and a better prognosis in patients AFB smear negative with HIV. The use of LJ culture and BacT/ALERT 3D System was useful to assure a total mycobacterial recovery.
Calculating the Phase Transformation Kinetics Using Impedance Spectroscopy for Sb2Te3  [PDF]

This paper describes a simple form, the theory to determine the crystallization fraction during the phase transformation of a solid, at a constant heating rate, from data obtained by impedance spectroscopy, where the change of the applied alternating voltage and measured current are proportional to the microstructural changes at the sample, corresponding to the volume fraction of a series layer model of two phases. To determine the volume fraction of each phase present in the sample, electrical data are obtained: conductivity and permittivity at DC, which are modeled by an electrical circuit composed by 2-RC, taking into that the permittivity and the occupied volume correspond to the filling fraction of each phase. By Cathodic Ersion or Sputtering, samples were obtained in film form of about 500 in thickness, composed of an alloy of Sb2Te3, in amorphous phase. To ensure the existence of the phase transformation in the sample, phase transition tests are performed by changes in: Reflection Optics, Electrical Resistivity and X-Ray Diffraction, showing clearly the presence of such a transformation. In the final part of this work, it completely shows the experimental results, giving a clear and precise idea of the kinetics of phase transformation of Sb2Te3 alloy, by impedance spectroscopy technique, which proves to be a simple and practical calculation tool.
