- A participação ativa na liturgia : segundo a arte de celebrarPublication . Silva, Hélder Filipe Martins; Carvalho, Joaquim Augusto Félix deThe concept of “active participation” emerged in theological reflection in the 20th century. It became a fundamental concept in theological, liturgical, and pastoral reflection, which was developed and deepened before, during, and after the Second Vatican Council. This concept is examined from biblical, historical, and theological perspectives. The theological and liturgical reflection that evolved from the Liturgical Movement and with Vatican II emphasizes the importance of all the faithful participating in the liturgy, taking on their responsibility and commitment within the liturgical assembly and the ecclesial community, so that the liturgy may be experienced as an “art of good celebration.”
- Considerações sobre a divisão existente entre as marcas de forma e os desenhos ou modelos : confronto de regimes e cumulação de direitosPublication . Costa, Sebastião Maria Laranjeiro Corvo Gomes da; Rendas, Tito Filipe BugiaThe following work was elaborated as a thesis for the Masters of Law - Corporate Law program, of the Faculdade de Direito da Universidade Católica Portuguesa. We will reflect upon shape trademarks, and in particular, delimit them before the notion of industrial design. We will begin with an analysis of the trademark as one of the main rights of industrial property. Afterwards, we will characterize shape trademarks, with a heavy focus on the requirement of non-functionality. Subsequently we will go over the main elements of industrial designs. We will also do some consideration on the concept of trade dress. Lastly, we will undertake an evaluation of the key differences between shape trademarks and industrial designs as well as the possibility of them overlapping.
- The resilience of listeria monocytogenes to environmental stressorsPublication . Gonçalves, Catarina Ferreira; Magalhães, Rui Miguel Barros de Sousa; Teixeira, Paula Cristina MaiaThe protection of public health requires the implementation of rigorous food safety measures, particularly in relation to ready-to-eat products. Contamination by foodborne pathogens remains a major concern, especially in food-processing environments where microbial persistence can compromise hygiene standards. Among these pathogens, Listeria monocytogenes stands out due to its remarkable ability to survive under adverse conditions such as desiccation and high salinity. These traits complicate sanitation practices and increase the risk of contamination, especially when hygiene protocols in food processing environments are inadequate. Its ability to cross physiological barriers further reinforces its significance as a public health threat. In this context, the present study investigated the survival and stress responses of persistent, non-persistent, and clinical strains of L. monocytogenes under environmental conditions commonly associated with food products and processing facilities. The main objective was to advance the understanding of the bacterium’s adaptive responses, with implications for food safety and public health, by analyzing strain behavior under stress conditions. The specific objectives were: (i) to assess survival dynamics in sodium chloride at 20 °C; (ii) to evaluate survival following desiccation on stainless steel at 10 °C; and (iii) to determine the minimum inhibitory concentrations (MICs) of strains for benzalkonium chloride and peracetic acid. The results showed that persistent and non-persistent strains exhibited similar survival dynamics under osmotic and desiccation stress, with no statistically significant differences in inactivation kinetics. In contrast, disinfectant susceptibility assays revealed marked variability: while persistent and non-persistent strains demonstrated comparable responses to benzalkonium chloride, clinical isolates displayed significantly higher MIC values, indicating reduced sensitivity. For peracetic acid, susceptibility levels were similar across groups, although heterogeneity among individual strains indicated distinct adaptive responses. This study provides valuable insights into the survival and stress tolerance of L. monocytogenes under conditions relevant to food-processing environments. The findings reinforce the need for robust and comprehensive hygiene strategies, capable of addressing strain-level variability, thereby strengthening food safety management and public health protection.
