Evaluation of Employment Contentment among Nurses in Critical Care Settings
Fernandes, Filipe; Dias, Almeida; Araújo, Isabel; Ribeiro, Jorge; Vicente, Henrique; Neves, JoséIn Intensive Care Units (ICUs), nurses operate within an environment where data may be interpreted in entropic terms, directly influencing rapid decision-making and strategy formulation, i.e., this high-stakes environment necessitates seamless collaboration between nurses, physicians, and patients, which is vital for the association and consolidation of long-term objectives. Indeed, job satisfaction for nurses ...
Diary as a Tool to Mitigate Post-Traumatic Stress in Intensive Care Patients: A...
Araújo, Cristina; Alves, Tiago; Araújo, Isabel; Fernandes, Filipe; Araújo , Cristiana; Alves, Tiago; Araújo , Isabel; Fernandes , FilipeIntroduction: The Intensive Care Unit (ICU) environment may sometimes contribute to the development of Post-Traumatic Stress Disorder (PTSD) in critically ill patients. The use of ICU Diaries has been proposed as a promising tool to mitigate these effects and enhance patients’ emotional recovery. Objective: To analyse recent scientific literature on the impact of ICU Diaries as a tool to mitigate PTSD, identify...
O papel da neurossonologia em manter a estenose carotídea rádica assintomática
Delgado, Gabriela Rocha; Fernandes, Filipe; Nunes, Gil; Moreira, Mafalda; Costa, Elisa CamposIntrodução: A utilização de radiação ionizante nos casos de neoplasia da cabeça e do pescoço aumentou a sobrevivência, contudo, pode apresentar diversas manifestações e consequências adversas. O aumento do risco de estenose carotídea e doença cerebrovascular é significativo nestes doentes. Acredita-se que ela ocorra tanto por lesão endotelial direta como por alterações imunomoduladoras indiretas, processos este...
Exploring tribological characteristics of ZrN-MoSN composite films fabricated v...
Luan, Jing; Lu, Hongying; Xu, Junhua; Fernandes, Filipe; Evaristo, Manuel; Ma, Bingyang; Xie, Fuxiang; Cavaleiro, Albano; Ju, HongboAchieving the stringent demands of sustainable tribological industrial applications poses a significant challenge, particular in optimizing the self-lubricant performance of nitride-based films. This paper tackled this challenge by designing and depositing a series of ZrN-MoSN composite films with varying (Mo + S)/Zr ratios, employing RF magnetron sputtering, aimed to enhance the tribological properties through...
Effect of binder on oxidation properties of tungsten carbides: A review by a Co...
Fathipour, Zahra; Hadi, Morteza; Maleki, Mohammad Reza; Fernandes, Filipe; Fernandes, FilipeThis study presents a conceptual classification scheme to review the literature on improving the oxidation resistance of tungsten carbide by modifying the binder. The first parts of the article are dedicated to the specification of the databases, the search method, and the description of the criteria chosen to classify the articles. Then, the data collected are presented in statistical graphs according to the p...
Can ZrAlN thin films be used as thermistor sensors for temperature assessment?
Martins, Bruno; Patacas, Carlos; Cavaleiro, Albano; Faia, Pedro; Bondarchuk, Oleksandr; Fernandes, FilipeThe electrical characteristics and conduction mechanisms of ZrAlN thin films for their potential use as thermistor sensors were assessed. Various compositions of Zr1-xAlxN were synthesized by sputtering and studied up to 200 °C to understand their sensitivity and applicability. Among the compositions studied, the ones with x = 0.34 and x = 0.46 showed the highest sensitivities, reaching values close to 3000 K. ...
Design and development of porous CoCrFeNiMn high entropy alloy Cantor alloy wit...
Abid, Talha; Akram, M. Aftab; Karim, M. Ramzan Abdul; Fernandes, Filipe; Fernandes, Filipe; Zafar, Muhammad Farooq; Yaqoob, KhurramCoCrFeNiMn high entropy alloys are among the most well-studied high entropy alloys that exhibit reasonable strength and outstanding ductility. In the present study, porous CoCrFeNiMn foams have been developed by the addition of copper in the base high entropy alloy by arc melting followed by its removal through an electrochemical dealloying process. Microstructure characterization of the as-cast samples confirm...
Microstructure evolution and mechanical behavior of magnetron sputtering AlN–Al...
Ma, Bingyang; Sun, Boyuan; Li, Rongbin; Cao, Haoxin; Fernades, Filipe; Fernandes, FilipeIn this paper, a series of AlN–Al nanocomposite films are prepared by reactive magnetron sputtering. The effects of N2 flow rate on the microstructure and mechanical properties of the films are studied. The formation and evolution mechanism of the nanocomposite structure are revealed. The results show that with the decrease of N2 flow rate, the microstructure goes through three stages: pure AlN, amorphous Al su...
Expanding the applications of the wear-resistant titanium aluminum nitride thin...
Martins, Bruno; Patacas, Carlos; Cavaleiro, Albano; Faia, Pedro; Zorro, Fátima; Carbo-Argibay, Enrique; FGerreira, Paulo J.; Fernandes, FilipeThis study investigates an approach to temperature sensing by integrating Titanium Aluminum Nitride (TiAlN), originally engineered for wear and corrosion applications, as a temperature sensor within a multilayered thin film system. A nitride multilayer system was developed by physical vapor deposition (PVD) using a single four-target magnetron sputtering chamber; intermediate vacuum interruption steps were empl...
Effect of carburizing time treatment on microstructure and mechanical propertie...
Boumediri, Haithem; Touati, Sofiane; Debbah, Younes; Selami, Salim; Chitour, Mourad; Khelifa, Mansouri; Kahaleras, Mohamed said; Boumediri, KhaledGas carburizing significantly enhances the surface properties of low-alloy gear steels, resulting in superior micro-hardness, layer thickness, carbon content, and overall mechanical properties. Unlike other thermochemical processes such as nitriding and carbonitriding, which have limitations in core properties and hardening depth, gas carburizing offers unmatched surface hardness, wear resistance, and mechanica...
