Optimization and performance studies of PES/SAPO-34 membranes for CO2/N2 gas separation

SAPO-34 nanocrystals were prepared and used as inorganic filler in polyethersulfone (PES) membranes. The influence of preparation conditions on permeation properties of CO2 and N2 gases and CO2/N2 selectivity were studied to achieve the highest separation performance possible for this mixed-matrix membrane. Gas permeation properties of PES/SAPO-34 MMMs with different contents of SAPO-34, PES and initial film thickness were investigated according to a full factorial design of experiments (DOE). The permeation tests and DOE results revealed that the optimized conditions to maximize the selectivity for PES/SAPO-34 are: composition of 18.5 wt % of SAPO-34, 15 wt% of PES, and a casted film thickness of 400 μm resulting in a CO2/N2 selectivity of 30.85. The findings showed that a multivariable model was validated and able to predict the selectivity with determination coefficient R2 of 0.969 and the results are in accordance with values presented in literature for PES/ SAPO-34 membranes. An economic analysis shows that the commercial grade price for the optimized membrane is EUR 9.43/m2 which represents around 2.2 times cheaper than polymeric commercial membranes.The authors gratefully acknowledge the fundings from the Strategic Project of CIEPQPF (UIDB/00102/2020), CICECO-Aveiro Institute of Materials (UIDB/50011/2020, UIDP/50011/2020 & LA/P/0006/2020), CIMO (UIDB/00690/2020 and UIDP/00690/2020) and SusTEC (LA/P/0007/2021), financed by Fundação para a Ciência e Tecnologia (FCT) through national funds.

Evaluating the fire behaviour of cement-based lightweight materials with textile waste incorporation using a cone calorimeter

The conscientious utilization of natural resources and the efficient waste management have become a matter of great concern in recent years due to the harmful impacts on the environment. The construction sector presents itself as one of the sectors that most contributes to raw materials consumption and waste generation, demanding the investigation of more sustainable and ecofriendly building materials, where the valorisation of wastes originated from other industries can be promising. Following the sustainability concept in construction materials, this work investigates the potential use of textile waste in cement-based lightweight construction material, evaluating the fire reaction of the material using the cone calorimeter equipment. The samples were tested at three different radiant heat fluxes (35 kW/m2, 50 kW/m2, 75 kW/m2) to simulate different fire situations. For the highest heat flux, the lightweight construction element with textile waste incorporation showed a Heat Release Rate Average ≤ 18 kW/m2, a peak Heat Release Rate Average ≤ 60 kW/m2, and a Total Heat Release Average ≤ 33 MJ/m2. These results reveal a very satisfactory fire behaviour compared to other materials and show the suitability of using textile waste as lightweight cement-based materials.info:eu-repo/semantics/publishedVersio

Fire resistance of austenitic stainless steel beams with rectangular hollow sections

This paper presents a study on the structural behaviour of stainless steel profiles under fire conditions. An experimental campaign of three-point bending tests on rectangular hollow section beams of the grade 1.4301 (also known as 304) were conducted, considering both steady-state and transient state conditions. Prior to those tests, the mechanical characterization of the stainless steel was investigated. The constitutive laws obtained by tensile tests at high temperatures are compared with those recommended in Eurocode 3, whose respective material models were recently proposed for modifications, still requiring complete validation. In addition, numerical modelling of the bending tests has been performed afterwards achieving close approximation to the observed experimental results. Finally, analytical methods to predict the load-deflection behaviour are also presented. Good agreement between the considered methodologies was attained validating their application on the prediction of the fire behaviour of stainless steel beams.This research work was performed within the framework of the project ‘StaSteFi – Fire design of stainless steel members’, PTDC/ECIEGC/ 30655/2017, supported by the Portuguese Operational Programme ‘Competitividade e Internacionalização’ in its FEDER/FNR component, and the Portuguese Foundation for Science and Technology (FCT) in its State Budget component (OE).info:eu-repo/semantics/publishedVersio

Comunicação eficaz na transição de cuidados de enfermagem à pessoa em situação crítica, no serviço de urgência – implementação da metodologia ISBAR

A segurança dos doentes nos serviços de saúde, foi sempre uma preocupação dos gestores em saúde. Um dos aspetos que a pode comprometer, é a transferência de cuidados do doente entre os profissionais responsáveis por ele. Seja nas passagens de turno, ou transferências intra e inter-hospitalares. É essencial que seja estabelecida uma comunicação eficaz, de modo a assegurar a fluidez de assunção de cuidados e responsabilidades. Estes pressupostos evitam a ocorrência de efeitos adversos, de eventuais atrasos no diagnóstico e tratamentos, que podem dar origem a atrasos no restabelecimento da pessoa em situação crítica. Objetivos: Conhecer a perceção dos enfermeiros do Serviço de Urgência (SU), relativamente à informação transmitida durante as passagens de turno. Tornar mais eficaz a comunicação interpares, e garantir, como consequência, a segurança e a melhoria dos cuidados de enfermagem, nos momentos de transição de doentes, no SU. Metodologia: Trabalho realizado com base na metodologia investigação-ação, dividido em três processos metodológicos parcelares e consecutivos. Primeiramente, foi aplicado um questionário, a 59 enfermeiros em SU, com prestação direta de cuidados à pessoa em situação crítica. No segundo momento, foi realizado um diagnóstico de situação com a aplicação do Guia de Observação, durante os momentos de passagem de turno. No terceiro momento, após a análise dos resultados emergentes do Guia de Observação, foi criado, e implementado, o instrumento estruturado para aplicar nas passagens de turno, baseado na metodologia Identify, Situation, Background, Assessment e Recommendation (ISBAR), e aplicado novamente o Guia de Observação, para estudo de eficácia e/ou eficiência trazida por este instrumento. Resultados: A perceção dos enfermeiros sobre a comunicação durante as passagens de turno é favorável em relação à maioria dos aspetos abordados. Estes valorizaram a comunicação no contexto da equipa multidisciplinar, e aspetos relacionados com a importância da formação e da experiência profissional com a qualidade da comunicação. A perceção favorável do enfermeiro traduz-se no elevado nível de situações significativas (70 a 90%) que cerca de 80% enfermeiros reportam conseguir transmitir durante a passagem de turno. 36% dos participantes apontam a necessidade de melhorias, 65% relacionadas com a organização do processo de transição de cuidados e 45% com o problema das interrupções. Após a implementação da metodologia ISBAR nas passagens de turno, houve uma melhoria em vários aspetos, como se depreende da percentagem média de conformidade ser cerca de 69%, tendo melhorado cerca de 48%. O tempo de transmissão de informação aumentou, em média, 0,4 minutos por doente. Conclusão: Os resultados do presente trabalho apontam uma perspetiva favorável da perceção dos enfermeiros sobre a comunicação durante a passagem de turno, ainda que alguns aspetos tenham margem para melhoria, relacionados com a objetividade e pertinência da informação, e com a necessidade de ter um contexto calmo que favoreça a concentração, logo sem interrupções. Este contexto é, por sua vez, facilitador da mudança, como se veio a verificar ao comparar a qualidade da passagem de turno antes e depois de implementar a metodologia ISBAR, a certificação das melhorias demonstra o interesse e eficácia da sua utilização.Patient safety in health services has always been a concern of health managers. One of the aspects that can compromise it is the transfer of the patient's care between the professionals responsible for it. Be it in handovers, or intra and inter-hospital transfers. It is essential that effective communication is established to ensure the fluidity of the assumption of care and responsibilities. These assumptions prevent the occurrence of adverse effects, possible delays in diagnosis and treatment, which can lead to delays in the recovery of the person in critical condition. Objectives: To know the nurses’ perception in the Emergency Department (ED) regarding the information transmitted during handover. To make peer-to-peer communication more effective, and to ensure, consequently, the safety and improvement of nursing care, in moments of patient transition, in the ED. Methodology: This work was carried out based on the research-action methodology, divided into three partial and consecutive methodological processes. First, a questionnaire was applied to 59 nurses in the ED, with direct care provided to the critically ill person. In the second moment, a diagnosis of the situation was carried out with the application of the Observation Guide, during handovers. In the third moment, after the analysis of the results emerging from the Observation Guide, a structured instrument was created and implemented to be applied in handover, based on the Identify, Situation, Background, Assessment and Recommendation (ISBAR) methodology, and the Observation Guide was applied again to study the effectiveness and/or efficiency brought by this instrument. Results: Nurses' perception of communication during handover is favorable in relation to most of the aspects addressed. They valued communication in the context of the multidisciplinary team, and aspects related to the importance of training and professional experience with the quality of communication. The favorable nurses’ perception translates into the high level of significant situations (70 to 90%) that about 80% of nurses report being able to transmit during handover. 36% of the participants point to the need for improvements, 65% related to the organization of the care transition process and 45% to the problem of interruptions. After the implementation of the ISBAR methodology in handovers, there was an improvement in several aspects, as can be seen from the average percentage of compliance being about 69%, having improved about 48%. The information transmission time increased by an average of 0.4 minutes per patient. Conclusion: The results of the present study point to a favorable perspective of nurses' perception of communication during handover, although some aspects have room for improvement, related to the objectivity and relevance of the information, and to the need to have a calm context that favors concentration, thus without interruptions. This context is a facilitator of change, as it turned out when comparing the quality of handovers before and after implementing the ISBAR methodology, the certification of improvements demonstrates the interest and effectiveness of its use

Effect of the cleaning and disinfection methods on the hygienic conditions of fermentation tanks of table olives (Olea europaea L.) Negrinha de Freixo cultivar

This study aimed to evaluate and identify the microbial community attached to the surfaces of fermenter tanks used in table olive Negrinha de Freixo cultivar processing through molecular analysis and verify if the cleaning/ disinfection was done correctly. Four fermentation tanks previously used in table olive processing were sampled at three different inside areas: upper, middle, and lower. Before sampling, four cleaning/disinfection methods were applied to the tanks, including (i) pressurised water; (ii) a disinfectant product used to clean bowls (Vasiloxe); (iii) 10% sodium hydroxide solution (caustic soda liquid); and (iv) a disinfectant product used by the wine industry (Hosbit). For each sample collected, mesophilic aerobic bacteria, yeast and moulds (YMC), lactic acid bacteria (LAB), as well as total coliforms (TC) and Pseudomonas aeruginosa were evaluated. The results showed significant differences between the different cleaning/disinfection methods applied. The fermenter sanitised with only pressurised water showed a greater abundance of microorganisms than the others. Mesophilic aerobic bacteria were the predominant population, with counts ranging between 2.63 and 5.56 log10 CFU/100 cm2, followed by the moulds (3.11–5.03 log10 CFU/100 cm2) and yeasts (2.42–5.12 log10 CFU/100 cm2). High diversity of microbial communities was observed between the different fermenter tanks. The most abundant species belonged to Aureobasidium, Bacillaceae, Cladosporium, and Rhodotorula genera. LAB, TC, and P. aeruginosa were not detected. This study hopes to improve hygienic conditions and increase the quality assurance and safety of the final product.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support through national funds FCT/MCTES (PIDDAC) to CIMO (UIDB/00690/2020 and UIDP/00690/ 2020) and SusTEC (LA/P/0007/2021).

Characterization and bioactivity of copaiba essential oil carried in a self-nanoemulsifying drug delivery system

Copaiba essential oil (CEO) is the volatile part of copaiba balsam, which has been topically used for various inflammatory conditions. However, there are some concerns about the CEO safety for oral use. The lipophilic character of CEO also limits its application in the pharmaceutical field. This study prepared a selfnanoemulsifying drug delivery system (SNEDDS) containing CEO and evaluated its toxic effects against a primary culture from pig liver (PLP2) and Green monkey kidney cell line (Vero). The inhibition of oxide nitric production was also evaluated on RAW 264.7 macrophage cell line to access the anti-inflammatory effect. The CEO was extracted by hydrodistillation and β-caryophyllene accounted for 51.8% of the oil. The formulation (FSNEDDS) consisting of CEO, Cremophor and ethyl linoleate was characterized in relation to morphology, stability, rheology, simulated digestion and bioaccessibility in vitro. FSNEDDS displayed Newtonian flow behavior with viscosity depending only on temperature and, in an aqueous medium, it formed small spherical particles (<100 nm size diameter). The FSNEDDS showed higher oxidative stability than the non-formulated CEO. In the simulated digestion, FSNEDDS formed nanoemulsifying droplets in gastric phase and tiny micelles in intestinal phase, and a bioaccessibility of 63%. The FSNEDDS showed a superior anti-inflammatory activity (+11%) than non-formulated CEO and this beneficial concentration was achieved with a non-toxic concentration for none of the cell lines tested. In conclusion, FSNEDDS improves the physicochemical stability, bioaccessibility and bioactivity of CEO, and it could be a phytotherapic option for per oral administration to treat inflammatory diseases.The authors wish to thank the financial support of the Coordenaç˜ao de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) and of the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq).

The years with the highest percentage of patients admitted to Via Verde Sepsis were 2019 (41.1%) and 2018 (37.0%). The majority were admitted during the afternoon work shift (51.3%) and triaged with "Yellow" priority (52.2%). The respiratory starting point stood out (54.1%). The first line of antibiotics used was Ceftriaxone (55.1%) and the second line of antibiotics was Clarithromycin (11.1%), of which 13.0% were men. The majority of patients were discharged from hospital (39.2%) and admitted to the Medical Service (38.9%). Almost all patients had their Via Verde Sépsis activated during triage (93.7%). There was a low rate of patients who died (2,5%) N=8, of whom 4 (50,0%) were men and 4 (50,0%) women, with 5 (62,5%) in the 56-75 age group and 3 (37,5%) aged over 75, 6 were triaged with orange priority and 2 (25,0%)with yellow priority. Conclusion: Accurate triage, rapid recognition, early resuscitation, early administration of antibiotics and eradication of the source of infection are the key components in providing quality care in the event of sepsis. It is therefore essential to increase the activation of the Via Verde Sépsis protocol in order to reduce mortality

Magnesium and manganese induced changes on chemical, nutritional, antioxidant and antimicrobial properties of the pansy and Viola edible flowers

composition was determined using standard methods. Free sugars, fatty acids, organic acids, tocopherols, and phenolic compounds were analyzed using various HPLC and GC devises. The extract’s antimicrobial, antioxidant, cytotoxicity, and anti-inflammatory activity were assessed. The results indicated that Mg enrichment negatively affected plant growth and mineral accumulation but improved photosynthetic performance. The edible flowers contained significant amounts of protein, low levels of fat, and varying sugar contents, such as glucose and fructose. Various fatty acids and phenolic compounds were identified, with different concentrations depending on the treatment. The flowers exhibited antioxidant potential, antimicrobial activity, cytotoxic effects, and antiinflammatory properties. The correlations between the investigated parameters not only expand knowledge on Mg and Mn interaction but also catalyze significant advancements in sustainable agriculture and food health, fostering a healthier and more conscious future.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support through national funds FCT/MCTES (PIDDAC) to CIMO (UIDB/00690/2020 and UIDP/00690/ 2020) and SusTEC (LA/P/0007/2020).

Vivências dos enfermeiros no cuidado à pessoa em fim de vida no serviço de urgência

O Serviço de Urgência (SU) é direcionado para o doente crítico, com necessidade de estabilização emergente, estando subjacente o cuidado emergente. Mas não são só estes doentes que procuram este serviço, também os doentes em fim de vida com necessidades de cuidados paliativos (CP) entram na porta do SU, sendo necessário que os enfermeiros(as) que lá exercem possam dar uma resposta efetiva neste âmbito. Daí ser fulcral colocar ênfase à investigação de forma a refletir nas estratégias de intervenção mais adequadas a estas pessoas. Objetivo: Analisar as vivências dos enfermeiros no cuidado à pessoa em fim de vida (PFV), no SU. Metodologia: Estudo qualitativo. A recolha de dados foi realizada com recurso a uma entrevista semiestruturada a um grupo focal de sete enfermeiros participantes no estudo, de uma Unidade Local de Saúde (ULS) do Norte de Portugal, durante a primeira semana do mês de abril de 2023. Resultados: Os enfermeiros (as) atribuem o conceito de PFV a uma doença incurável com pouco tempo de vida. Ao conceito de CP associam a promoção de conforto e bem-estar ao doente, a promoção do bem-estar da família, os cuidados promotores de dignidade. Os sentimentos negativos vivenciados pelos enfermeiros expressam sentimentos negativos (frustração) e emoções negativas, como a tristeza, raiva e revolta. As principais intervenções destes enfermeiros dirigidas à PFV enquadram-se no paradigma paliativo como alívio dos sintomas, apoio ao doente e à sua família e proporcionar medidas de conforto. Consideram intervenções fundamentais dirigidas à PFV, o conforto físico e psicológico, dando-se ainda enfâse ao toque. Apontam para a adoção de medidas terapêuticas centradas na abordagem curativa com a formatação e formação recebida e a pressão da família. Foi possível distinguir nas dificuldades a “Sobrecarga de trabalho”, “Dificuldades de apoio ao nível da instituição”, “Dificuldades ao nível dos recursos”. Por sua vez, de entre as necessidades sentidas emergiram a “Necessidade de uma estrutura física adequada”, “Necessidade de melhoria ao nível organizacional”. Todos foram unânimes em salientar a falta da dignidade para a PFV no SU, por razões físicas/estruturais e por défice de formação. Como estratégias de melhoria, os enfermeiros propõem: o investimento nas equipas multidisciplinares, a melhoria da estrutura física e a uniformização de procedimentos na abordagem da PFV. Conclusão: Os resultados apontam para um leque de dificuldades associadas às vivências dos enfermeiros no cuidado à PFV, contudo também emergem estratégias de melhoria. Devem ser promovidas estratégias organizacionais e individuais. Um exemplo seria a formação/ promoção de atividades de melhoria das estratégias de coping, visando facilitar a gestão dos sentimentos e emoções por parte dos enfermeiros. Das várias medidas propostas destaca-se a criação de uma rede de urgência de CP.The Emergency Service (ES) is geared towards critically ill patients in need of emergent stabilization, with emergent care as its underlying principle. But it's not only these patients who come to this service. End-of-life patients in need of palliative care (PC) also enter the ES, and nurses working in these services need to provide an effective response in this area. That's why it's crucial to put the emphasis on research in order to reflect on the most appropriate intervention strategies for these people. Objective: To analyze the experiences of nurses in caring for people at the end of life (PEL) in the ES. Methodology: A qualitative study. Data was collected using a semi-structured interview with a focus group of seven nurses participating in the study, from a Local Health Unit in Northern Portugal, during the first week of April 2023. Results: Nurses attribute the concept of PEL to an incurable disease with a short time to live. To the concept of PC they associate the promotion of comfort and well-being for the patient, the promotion of the family's well-being and care that promotes dignity. The negative feelings experienced by the nurses express negative feelings (frustration) and negative emotions, such as sadness, anger, and revolt. These nurses' main interventions aimed at the PEL fall within the palliative paradigm, such as relieving symptoms, supporting the patient and their family and providing comfort measures. They consider physical and psychological comfort to be fundamental interventions aimed at the PEL, with an emphasis on touch. They point to the adoption of therapeutic measures centered on the curative approach with the formatting and training received and pressure from the family. Difficulties included "Work overload", "Difficulties with support from the institution" and "Difficulties with resources". Among the needs felt, the following emerged: "Need for an adequate physical structure", "Need for organizational improvement". All were unanimous in highlighting the lack of dignity for PEL in the ES, due to physical/structural reasons and a lack of training. As strategies for improvement, the nurses propose: investing in multidisciplinary teams, improving the physical structure, and standardizing procedures for dealing with PEL. Conclusion: The results point to a range of difficulties associated with nurses' experiences in caring for people at the end of life, but strategies for improvement also emerge. Organizational and individual strategies should be promoted. One example would be training / promoting activities to improve coping strategies, with the aim of making it easier for nurses to manage their feelings and emotions. Of the various measures proposed, the creation of an emergency PC network stands out
