Comparison of milk-clotting activity measurement using the Berridge's operator-...
Gomes, Sandra; Martins, António P. L.; Reboredo, Fernando; Caeiro, José; Martins, João; Dias, João; Alvarenga, NunoThe milk clotting activity (MCA) analysis of coagulants used in the production of cheese is an important parameter used in the modern dairy industry. The MCA is calculated using the estimated milk-clotting time (MCT). The standard method used for estimation of MCT is presented in the ISO 23058/IDF 199 Standard using the Berridge’s operator-based approach. In this paper a new method is presented to estimate the ...
IoT lysimeter system with enhanced data security
Almeida, Carlos; Santos, João Miguel; Caeiro, José; Martins, JoãoDiverse sources of data related to precision agriculture may be acquired with devices using an IoT architecture. Lysimeters are used to measure the amount of actual evapotranspiration released by plants, which is an important parameter for agriculture. New proposals of lysimeters extend the capabilities of these devices taking advantage of modern electronics, sensors, Internet, and computing devices. The paper ...
Smart Lysimeter with Crop and Environment Monitoring
Almeida, Carlos; Santos, João Miguel; Caeiro, José; Oliveira, Henrique; Martins, JoãoA model of a smart lysimeter, adopting an IoT approach, enhanced with pest and crop state analysis is presented. Besides the measurement of the traditional evaporation-transpiration balance, the lysimeter senses additional parameters like the soil temperature and humidity at different depths; air temperature and humidity; sunlight exposition (visible and infrared). Additionally, the system can capture high-reso...
Hydrometeorological monitoring iot system: The software architecture
Carvalho, Raúl; João Miguel, Santos; Palma, Patrícia; Caeiro, José; Santos, João; Martins, JoãoAn Internet of Things system designed for the collection and processing of surface water quality and meteorological data is presented. The open source software architecture is an important aspect of the design of this system, based on common commercial of the shelf components. It integrates: low power microcontrollers and single board computers to acquire and process the data from the most common parameters mea...

Alvarenga, Nuno; Martins, João; Caeiro, José; Garcia, João; Passáro, João; Coelho, Luis Manuel Rodrigues; Santos, Maria Teresa; Lampreia, CéliaTraditional ewe’s cheese producers face certain challenges caused by fluctuating envi- ronmental parameters inside the ripening room, which lead to lack of homogeneity in the final product. The present research discusses the application of computer fluid dynamics for simulating the distribution of environmental parameters, predicting the airflow pattern, and identifying critical areas where such parameters coul...

Impact of environmental conditions on the ripening of Queijo de Évora PDO cheese
Lage, Patricia; Borrega, Joana; Lampreia, Célia; Pássaro, João; Caeiro, José; Gonçalves, Elsa M.; Martins, António; Dias, João; Alvarenga, Nuno‘‘Queijo de Évora’’ is a traditional Portuguese cheese from raw ewe’s milk and granted with PDO label. It is ripened traditionally in rooms with empirical control of temperature and humidity. Nowadays, almost all cheese factories use rooms with temperature and humidity control, but still a significant heterogeneity among cheeses is acknowledged due to unequal distribution of environmental conditions. This paper...
A nursing care intervention model for elderly people adopting self-care as a ce...
Lopes, Manuel; Marôco, João; Fonseca, César; Santos, Margarida; Caeiro, José; Oliveira, Henrique; Goes, MariaObjectives: A core set of International Classification of Functioning, Disability and Health codes was used, to ascertain the general profile of functionality as a function of biological and sociodemographic characteristics and to determine systematized nursing interventions in accordance with self-care needs identified with the study of self-care behavior, in elderly living in extensive and sparsely populated ...

Lopes, Manuel; Marôco, João; Fonseca, César; Santos, Margarida; Caeiro, José; Oliveira, Henrique; Goes, MariaObjectives: A core set of International Classification of Functioning, Disability and Health codes was used, to ascertain the general profile of functionality as a function of biological and sociodemographic characteristics, notably the age of the citizens. Methods: Data were collected by health professionals in the participants’ houses. The factorial validity of the construct was assessed by a confirmatory fac...
