Nutrient adequacy of Nfuma, the flour from Strychnos Madagascariensis fruit
Ribeiro, M.; Chemane, S.; Pinto, Edgar; Khan, M.; Ferreira, I.M.P.L.V.O.; Casal, S.; Pinho, O.; Viegas, O.African native fruits play a significant role in reducingmicronutrient deficiencies and increasing the income of poor rural communitiesin developing countries. In Mozambique, the fruit of Strychnosmadagascariensis is usually processed into flour, nfuma, and is consumed by local communities during staple food shortage.However, there is practically no data on its nutritional value. Therefore, this study aimed to ...
Simultaneous speciation analysis of Hg and Se in fish by high-performance liqui...
Ribeiro, M.; Galli, E.; Guérin, T.; Silva, J.A.L.; Castanheira, I.; Leufroy, A.; Jitaru, P.This study reports the development and validation of a new analytical method for simultaneous speciation analysis of Se and Hg in fish muscle. For this purpose, four Se species (selenite/Se(IV), selenate/Se(VI), selenomethionine/SeMet, and selenocysteine/SeCys) and two Hg species (inorganic mercury/iHg and methylmercury/MeHg) were extracted simultaneously by microwave-assisted enzymatic hydrolysis and then sepa...

Paz, G.; Vale, C.; Teles, E.; Teixeira, C.; Ribeiro, M.; Martins, I.; Viegas, A.; Pereira, T.; Rosa, M.; Fernandes, F.Introduction and Objectives: Increasing number of studies show an association between overweight and obesity with arterial hypertension in childhood. The aim of this study was to assess body mass index (BMI) and high blood pressure (HBP) and its association in children and adolescents.Methods: Observational, cross-sectional and analytical study. Data was collected from the medical records of patients between 5 ...
Assessment of the mercury-selenium antagonism in rainbow trout fish
Ribeiro, M.; Zephyr, N.; Silva, J.A.L.; Danion, M.; Guérin, T.; Castanheira, I.; Leufroy, A.; Jitaru, P.This study aims at the assessment of mercury (Hg)-selenium (Se) antagonism in fish. For this purpose, rainbow trout fish (Oncorhynchus mykiss) were exposed to methylmercury (MeHg) under controlled conditions, in the presence or absence of selenomethionine (SeMet) using an in-house prepared diet (enriched with MeHg and SeMet at 0.2 μg/g and 5.0 μg/g, respectively). The total duration of the exposure study was 3 ...
The influence of a dentin desensitizer on the microtensile bond strength of two...
Seara, S. F.; Erthal, B. S.; Ribeiro, M.; Kroll, L. [UNESP]; Pereira, G. D.S.Made available in DSpace on 2022-04-28T18:54:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2002-01-01; A laboratory study evaluated the influence of a dentin desensitizer (D/Sense 2) on the microtensile bond strength of two adhesive systems: a self-etching primer (Bistite II SC) and a one-bottle adhesive (Prime & Bond 2.1). Sixteen crown dentin discs were obtained from extracted sound human third molars....
System-level assessment of low complexity hybrid precoding designs for massive ...
Pavia, J. P.; Velez, V.; Souto, N.; Ribeiro, M.; Sebastião, P.; Correia, A.The fast growth experienced by the telecommunications field during the last few decades has been motivating the academy and the industry to invest in the design, testing and deployment of new evolutions of wireless communication systems. Terahertz (THz) communication represents one of the possible technologies to explore in order to achieve the desired achievable rates above 100 Gbps and the extremely low laten...
Phase shift optimization algorithm for achievable rate maximization in reconfig...
Praia, J.; Pavia, J. P.; Souto, N.; Ribeiro, M.Terahertz (THz) band communications are considered a crucial technology to support future applications, such as ultra-high bit rate wireless local area networks, in the next generation of wireless communication systems. In this work, we consider an ultra-massive multiple-input multiple-output (UM-MIMO) THz communication system operating in a typical indoor scenario where the direct link between the transmitter ...
Ribeiria pholadiformis Sharpe in Ribeiro (Rostroconchia): history of the study,...
Ribeiro, M.; Nunes, Andreia; Pereira, SofiaABSTRACT: Ribeiria pholadiformis Sharpe in Ribeiro, the type-species of Ribeirioida (Rostroconcha), was erected almost 170 years ago, based on portuguese fossils from the Middle Ordovician of the Buçaco Syncline. In this paper, we review the history of the study of this species and clarify the type-locality and unit for this taxon: the Cácemes Group (Darriwilian) in the Palheiros stream section (Penacova). The ...
