Evolução do coberto vegetal na rede de soutos demonstração

Patrício, Maria Sameiro; Nunes, Luís; Ramos, António; Raimundo, F.

O coberto vegetal foi avaliado anualmente de 2019 a 2022. Esta análise consistiu na caracterização da biodiversidade florística, fitovolume e biomassa do coberto herbáceo e arbustivo. Nos SD de Parada e Salgueiros o coberto vegetal foi avaliado 4 anos consecutivos. Nos restantes SD foi avaliado uma a duas vezes pelo facto de ter havido mobilização para controlo da vegetação nos primeiros anos. A caracterização ...

Peaches Detection Using a Deep Learning Technique - A Contribution to Yield Est...

Assunção, Eduardo Timóteo; Gaspar, Pedro Dinis; Mesquita, Ricardo; Simões, Maria Paula; Ramos, António; Proença, H.; Inácio, Pedro R. M.

Fruit detection is crucial for yield estimation and fruit picking system performance. Many state-of-the-art methods for fruit detection use convolutional neural networks (CNNs). This paper presents the results for peach detection by applying a faster R-CNN framework in images captured from an outdoor orchard. Although this method has been used in other studies to detect fruits, there is no research on peaches. ...

Apple and Pear Model for Optimal Production and Fruit Grade in a Changing Envir...

Sousa, Miguel L.; Gonçalves, Marta; Fialho, Délia; Ramos, António; Lopes, João P.; Oliveira, Cristina M.; Melo-Abreu, J.P.

Apple and pear crops are very important to the rural economy of Portugal. Despite significant improvements in productivity and quality, due to the introduction of new management techniques, model-based decision support may further increase the revenue of the growers. Available simulation models of orchard growth and production are scarce and are often highly empirical. This study presents a mechanistic model fo...


In sickness and in health: the oxygen reactive species and the bone

Reis, Joana; Ramos, António

Oxidative stress plays a central role in physiological and pathological bone conditions. Its role in signalment and control of bone cell population differentiation, activity, and fate is increasingly recognized. The possibilities of its use and manipulation with therapeutic goals are virtually unending. However, how redox balance interplays with the response to mechanical stimuli is yet to be fully understood. ...

A preliminary analysis of the wear pathways of sliding contacts on temporomandi...

Pinto-Borges, Henrique; Carvalho, Óscar Samuel Novais; Henriques, Bruno Alexandre Pacheco de Castro; Silva, Filipe Samuel; Ramos, António

In the last years, several materials and design have been assessed in an attempt to improve the mechanical performance of temporomandibular joint total joint replacement (TMJ TJR) prostheses. However, the wear of the TMJ TJR condyle to the polymer-based fossa component during loading and sliding movements. That promotes the release of debris and risks of toxicity to the surrounding tissues. The purpose of this ...

Pinto-Borges, Henrique; Carvalho, Óscar; Henriques, Bruno; Silva, Filipe; Ramos, António; Souza, Júlio

Temporomandibular joint (TMJ) prostheses can be a stock or custom-made replacement of the related maxillomandibular structures such as condyle and fossa. In the last years, several materials and design have been assessed in an attempt to improve the mechanical performance of TMJ prostheses. This study aims to report literature data on the wear of temporomandibular joint prostheses and potential biological risks...

Finite element model validation based on an experimental model of the intact sh...

Bola, Margarida; Simões, José; Ramos, António

The shoulder joint is a complex anatomical system. The main goal of this study was to build a Finite Element (FE) model of the intact shoulder joint and its validation was done using an experimental model comparing cortical strains. Considering the expected differences between the experimental model and an in vivo shoulder, the experimental model developed replicates adequately the in vivo functioning of the jo...
