ABSTRACT

Wireless fidelity (WiFi) networks are deployed in several varied environments all around the World. Usually, the wireless fidelity access points are always on in houses and other small companies. In buildings of large companies and public organizations and in university campuses the number of access points is elevated; they are powered using power over the ethernet and are always on. Consequently, they consume a considerable amount of electric energy. The last versions of the International Electric and Electronic Engineers 802.11 standardized procedures to save energy in a wireless fidelity terminal but not in the access point. We designed a formal method to show when energy can be saved in wireless fidelity access points considering different power supplies for the access point: an electric energy battery and a standard voltage supply. We use an external battery that stores electric energy during an interval of time from a standard voltage supply (Charge period). After that interval (Discharge period), the energy supply for the access point is the external battery. Those intervals of time are repeated sequentially (Charge and Discharge cycles). We verified our formal model implementing a hardware circuit that controls the power supply for the access point. The amount of energy saving for a large number of of access points during a long period of time is considerably high.

ABSTRACT

La técnica de cateterización de la arteria axilar es factible de utilizar para monitorización de rutina y su colocación es relativamente sencilla y accesible a personal no entrenado previamente. Su tasa de complicaciones evaluadas es baja, así como el mal funcionamiento y las retiradas accidentales. La alta tasa de puntas de catéter infectadas pueden deberse más a causas multifactoriales del tipo manipulación del catéter, incumplimiento de las normas del CDC y colocación en pacientes previamente sépticos. No hubo correlación entre punta de catéter positiva y el aspecto del sitio de entrada. Se planifica rediseñar un protocolo que permita evaluar mejor las complicaciones infecciosas comparándolos con otros sitios de abordaje

ABSTRACT

1.-Las cifras del recuento globular guardan paralelismo con el índice plasmático globular, 2.-La cifra media del recuento globular en los 200 casos estudiados es: 4.570.300, 3.-La cifra media de la relación plasmatico globular es de 45.735 porciento, 4.-La determinacion del recuento globular, la relación plasmático globular y la hemoglobina nos permiten obtener las constates hematimétricas de gran utilidad en la clsificación de las anémias, 5.-La cifra más baja del recuento globular es de 3.900.000 p.mm3, 6.-La cifra más elevada es de 5.900.000 p.mm3, 7.-En vista de los resultados obtenidos en la actualidad para tener una relacion exacta del número de hematies se debe solicitar el hematocrito
