Little is understood about which factors affect a software process improvement (SPI) initiative in a governmental organization and how the organization's environment determines these factors. This lack of understanding can inhibit SPI initiatives in organizations that find themselves too small for formal SPI models or standards. The main objective of our(More)
This study tested whether alpha-adrenoceptor-mediated coronary vasoconstriction is augmented during exercise in diabetes mellitus. Experiments were conducted in dogs instrumented with catheters in the aorta and coronary sinus and with a flow transducer around the circumflex coronary artery. Diabetes was induced with alloxan monohydrate (n = 8, 40 mg/kg(More)
The real value of electronic signatures is not in their application to software products but in the level of security and trust they provide in a process. They should be able to provide identification of a sender and at the same time, they should be easy to use, and meet all legal and regulatory requirements as indicated by the legislation. It is obvious(More)
As arterial partial pressure of O(2) (Pa(O(2))) is reduced during systemic hypoxia, right ventricular (RV) work and myocardial O(2) consumption (MVo(2)) increase. Mechanisms responsible for maintaining RV O(2) demand/supply balance during hypoxia have not been delineated. To address this problem, right coronary (RC) blood flow and RV O(2) extraction were(More)

A mis padres y hermano. por el apoyo económico que me brindó. El presente trabajo describe el proyecto de tesis llamado "Procesador Educativo con los Circuitos AMD29300" (que se le ha dado el nombre de MIRAGE), la cual se compone de dos partes principales: el diseño-físico del procesador (tipo RISC) y un modelo computacional del mismo. Teniendo como(More)
