Assessment of influential operational parameters in the mitigation of CO2 emiss...
Balanuta, Vítor; Baptista, Patrícia; Carreira, Fernando; Duarte, Gonçalo; Casaca, Cláudia S. S. L.The European decarbonization goals and requirement for energy independence are mostly relying on intermittent renewable energy sources for electrification. A numerical model was developed to simulate the operation of a steam generator, allowing a study of the potential impacts of retrofitting existing coal-fired power plants to operate with biomass or coal–biomass mixtures on combustion parameters and CO2 emiss...
Case Report and Literature Review of Cardiac Amyloidosis: A Not-So-Rare Cause o...
Baptista, Patrícia; Moura De Azevedo, Sofia; Alexandre, André; Dias-Frias, AndréRestrictive cardiomyopathy secondary to cardiac amyloidosis is an underdiagnosed cause of heart failure and it is associated with significant morbidity and mortality. The most common types of amyloidosis are light chain amyloidosis, transthyretin amyloidosis and secondary amyloidosis. We report the case of a 84-year-old man that presented with new onset signs and symptoms of heart failure. Multimodality imaging...
A Rare Case of Mediastinal Mass: Thymoma and Thymic Tumor
Moura De Azevedo, Sofia; Baptista, Patrícia; Pichel, Rita C; Dias, Rita R; Bertão, ManuelaThymomas and thymic carcinomas are rare mediastinal neoplasms arising from thymic epithelial cells, and the presence of synchronous or metachronous primary thymic neoplasms in a single patient is an extremely rare event. Thymoma patients appear to have an inherent predisposition toward developing additional neoplasms. This additionally presents a diagnostic challenge, revealing the importance of multidisciplina...
Osteogenesis Imperfecta in Adults: Experience of a Hospital Center
Sousa Martins, Rute; Baptista, Patrícia; Rocha, Sara; Guimas, Arlindo; Ribeiro, RosaIntroduction: Osteogenesis imperfecta (OI) is a rare genetic disease characterized mainly by bone fragility and can have a series of systemic manifestations. Its management involves a multidisciplinary approach. The authors intend to describe the characteristics of an adult population with OI and evaluate the treatment used. Material and Methods: An observational and retrospective study based on data obtained f...

Photovoltaic integrated electric vehicles: assessment of synergies between sola...
Sagaria, Shemin; Duarte, Gonçalo; Neves, Diana; Baptista, PatríciaElectric vehicles are promoting sustainable developments in the automotive industry. But the short driving range has been an inconvenience to the electric vehicle (EV) users. This paper evaluates the potential of Photovoltaic integrated into EV in real-world conditions to assess energy consumption, range and EV's charging frequency for battery and fuel cell powertrain configurations. A simulation model is devel...
Systematic method for developing reference driving cycles appropriate to electr...
Watling, David; Baptista, Patrícia; Duarte, Gonçalo; Gao, Jianbing; Chen, HaiboIncreasingly, demanding environmental standards reflect the need for improved energy efficiency and reduced externalities in the transportation sector. Reference driving cycles provide standard speed profiles against which future developments and innovations may be tested. In the paper, we develop such profiles for a class of electric L-category vehicles, which are anticipated to play an increasing future role ...
Including engine data for energy and pollutants assessment into the vehicle spe...
Mera, Zamir; Varella, Roberto; Baptista, Patrícia; Duarte, Gonçalo; Rosero Obando, FredyVehicle emission models are relevant for evaluating the performance of vehicle technologies and help in the definition of environmental policies. This paper presents an improved emissions modelling approach (named VSP+M) by combining the vehicle specific power (VSP) with load-regime engine maps for each VSP mode. The new modelling enabled to link tailpipe emissions to vehicle and engine operating conditions, ob...
Assessment of wireless charging impacts based on real-world driving patterns: C...
Duarte, Gonçalo; Silva, André; Baptista, PatríciaIn the current transition to a smarter and more efficient transportation system, battery electric vehicle mileage and the time required for charging are still two main constraints that need to be overcome to enable a larger penetration of electric vehicles. Moreover, the few charging stations available are a consequence of the "supply and demand" problem. Consequently, wireless dynamic recharging can be a compl...
