Our objectives were to assess the efficacy and toxicity of gemcitabine plus cisplatin as first-line therapy in metastatic breast cancer (MBC). Patients with stage IV MBC and no prior chemotherapy for metastatic disease were treated with gemcitabine 1200 mg/m on days 1 and 8, and cisplatin 75 mg/m on day 1 every 21 days. Up to 6 cycles were given. A total of(More)
Minix is a Unix clone Operating Systems to be run on IBM PCs and compatibles, designed by Tanembaum [10] for courses in the area.Accepting the Tanembaum's proposal, this document describes the results of some extensions on the internal work of Minix as an exercise on Operating Systems Design and Implementation that attempts to transfer that experience to(More)
Intelligent agents have to be provided with different skills and technological resources in order to deal with highly changing environments, uncertain, incomplete and potentially inconsistent information and bounded computational resources. BDI architectures, argumentation-based techniques and recent technologies like web services have been incorporated in(More)
This paper describes the kernel and user interface designs of a Network Operating System for a Local Heterogeneous Area Network. The main goal of the project is to create a kernel to manage the distribution of a restricted set of functions or services between the network nodes, allowing portability of these functions within machine and Operating Systems(More)

Direct irradiation of fenvalerate (FV) in aqueous solution (4 x 10(-3) M) gives rise to 2,3-diarylisohexanitrile through the homolytic CO-CH(i-Pr) bond cleavage, followed by a rapid decarboxylation of the primary carbonyloxy radical, and radical recombination. The unusual exclusive formation of the cross combination product suggests that the persistent free(More)
