13. Suporte ao serviço não orientado a conexão na rede digital de serviços integrados de faixa larga
Este trabalho aborda o suporte ao serviço não orientado à conexão pela Rede Digital de Serviços Integrados de Faixa Larga (B-ISDN), concentrando-se, especificamente, na interconexão de redes locais. São apresentadas as alternativas de arquitetura de rede, identificando os elementos de rede envolvidos e as opções de implementação destes elementos.

14. CONTROLE DE CONGESTIONAMENTO NA REDE DIGITAL DE SERVIÇOS INTEGRADOS DE FAIXA LARGA UTILIZANDO O MODO TRANSFERÊNCIA ASSÍNCRONO / CONGESTION CONTROL FOR BROADLAND INTEGRATED SWITCHED DIGITAL SYSTEMS USING THE ASYNCHRONOUS TRANSFER MODE
Broadbend Integrated Services Digital Networks (B-ISDN) are characterized by their flexibility of integrating a variety of traffic sources such as, voice, data and video. Congestion control of these networks is studied in this work. Through simulation of traffic sources, it have been possible to explore statistical multiplexing gain reached by the Asynchrono

15. Effect of isosorbiddinitrate on exogenously expressed slowly activating K+ channels and endogenous K+ channels in Xenopus oocytes.
1. The effects of isosorbiddinitrate (ISDN) were tested on membrane currents and resting potential in Xenopus laevis oocytes which were either uninjected or injected with cRNA encoding for K+ channels from three distinct families (slowly activating IsK channels, delayed-rectifying Kv1.1 or inwardly rectifying IRK1 K+ channels). 2. In uninjected oocytes ISDN

16. Dilation of coronary artery stenoses after isosorbide dinitrate in man.
The effect of isosorbide dinitrate (ISDN), 5 mg sublingually, on the diameters of coronary artery stenoses (n = 27) was examined in 20 patients. Another 18 patients with angiographically normal coronary arteries received the same amount of ISDN and were used as controls. Prestenotic and stenotic diameters were measured with a vernier calliper having an accur

17. Non-invasive measurement of endothelial function: effect on brachial artery dilatation of graded endothelial dependent and independent stimuli.
OBJECTIVE: To examine the relation between endothelial dependent and endothelial independent stimuli of varying intensity and measures of vascular function in the brachial artery of young healthy adults, to determine whether these responses are consistent and can be used to assess endothelial function. DESIGN AND SETTING: High resolution ultrasound was used

18. The Implementation of Telemedicine within a Community Cancer Network
Telemedicine is being used by physicians at the member hospitals of the Jefferson Cancer Network (JCN) for consultations regarding the diagnosis and management of cancer patients. The technology employed for this telemedicine system was chosen to meet three related specifications: low capital and operating cost, internal maintainability by community hos

21. The medical libraries of Vietnam--a service in transition.
The medical libraries of Vietnam maintain high profiles within their institutions and are recognized by health care professionals and administrators as an important part of the health care system. Despite the multitude of problems in providing even a minimal level of medical library services, librarians, clinicians, and researchers nevertheless are determine
