Neonatal anoxia is a worldwide clinical problem that has serious and lasting consequences. The diversity of models does not allow complete reproducibility, so a standardized model is needed. In this study, we developed a rat model of neonatal anoxia that utilizes a semi-hermetic system suitable for oxygen deprivation. The validity of this model was(More)
This paper presents an enhanced 32-bit carry look-ahead (CLA) adder implemented using the multi-output enable /disable CMOS differential logic (MOECDL) style. The MOECDL structure proposed represents a promising technique for iterative networks and self-timed circuits. The recursive property of CLA algorithm has been efficiently exploited to demonstrate the(More)
Bradykinin (BK) produced concentration-related relaxations of cat middle cerebral arteries and was ineffective in cat basilar arteries. On rabbit basilar arteries, BK initially produced concentration-related relaxations; however, when repeated at 2-hour intervals, BK eventually produced pure contractile responses. After preincubation of the tissues with(More)
Neonates that suffer oxygen deprivation during birth can have long lasting cognitive deficits, such as memory and learning impairments. Hippocampus, one of the main structures that participate in memory and learning processes, is a plastic and dynamic structure that conserves during life span the property of generating new cells which can become neurons,(More)
The aim of this paper is to verify the nature of the relationship between the concept of legitimacy and the phenomenon of institutionalization of operational auditing at the Court of Auditors in a context of institutional isomorphism. A documental examination was conducted covering the period of 1987 to 2004 and 18 people involved in the aforementioned(More)
