Exogenous administration of 5-aminolaevulinic acid (ALA) is becoming widely used to enhance the endogenous synthesis of protoporphyrin IX (PpIX) in photodynamic therapy (PDT) and fluorescence photodetection (PD). Recently, results have shown that the chemical modification of ALA into its more lipophilic esters circumvents limitations of ALA-induced PpIX(More)
Heterogeneous wireless access networks (HWAN) will create a market for the delivery of an extensive collection of novel and attractive services and contents. Accounting and pricing the ubiquitous services will play a key role from both service providers and users point of view. By one hand, wireless service providers (WSP) look for the maximum revenue and(More)
Vehicular Ad-hoc Networks (VANETs) are currently in everyone's mouth when talking about future technologies that will be implemented in the automotive industry. In the last years the IEEE group has been working in the development of a standard for vehicular communications, this standard is the 802.11p. Most research work in this area has focused on(More)
In this paper we propose the application of intelligent agents in traffic-lights, for the road control of urban transit in the city of Colima, México; using a multi-agent approach for dynamic urban traffic-lights system coordination that relies on locally available traffic data and the traffic condition of the neighboring intersections. According to(More)
The evolution of wireless communications over the last years has resulted in a clear trend towards Beyond Third Generation (B3G) systems, supporting the integration and coexistence of multiple, diverse Radio Access Technologies (RATs) in a common composite radio environment. This integration gives user a great flexibility in choosing access cells with(More)
The next generation of mobile networks is expected to utilize multiple radio access technologies (RAT), seamlessly integrated to form a heterogeneous wireless network. On the arrival of service request, an access network must be assigned to the user. A request can be due to a new connection call within a cell, an intra- system or inter-system handover(More)

The morphology and ultrastructure of cell nuclei in neurons of the third abdominal ganglion of crayfish were studied from alternating series of ultrathin and semithin sections. The ganglion contains approximately 850 neurons with sizes between 10 and 200 microm. Cell nuclei show a great variability. Their size, the chromatin distribution, the number of(More)
