INTRODUCTION: Penetrating keratoplasty (PK) is one of the most common surgical procedure in corneal transplantation worldwide. Graft failure and rejection risk progressively increases with the increasing number of quadrants with corneal neovascularization (CNV). Optical coherence tomography angiography (OCTA) is a noninvasive imaging technique that has been widely used to visualize vascular abnormalities in the...
A queratoplastia penetrante (QP) é um dos procedimentos cirúrgicos mais realizados na transplantação corneana mundialmente. A falência do enxerto e o risco de rejeição aumentam progressivamente com o aumento do número de quadrantes com neovascularização corneana (NVC). A angiografia por tomografia de coerência ótica (OCTA) é um exame não invasivo que tem sido largamente utilizado na visualizaçã...
This paper addresses aspects of design and planning of a Wireless network WiMAX (IEEE 802.16) to establish a point-to-point, PTP, link from the Health Sciences Faculty of University of Beira Interior (FCS/UBI) to Hospital Sousa Martins (Guarda), and also presents a field trial where we tested point-to-point links with pre-WiMAX equipment. The design of the link had into consideration the carrier to noise ratio,...
