Water Enhancement on CO2 adsorption: Equilibrium studies on an amine sorbent for Direct Air Capture

This work aims to establish a relationship between CO2 adsorption capacity and water, in the context of CO2 removal directly from atmosphere (DAC). For this, experimental data was ob- tained for a broad range of humidity, temperatures and concentrations of CO2 , using a sup- ported amine sorbent. Subsequently, the CO2 adsorption results were fitted to equilibrium models from literature and compared with experimental trends. The Stampi-Bombelli and WADST models revealed the best fittings, being both values of SSR and R2 relatively close (SSR=0.338, R 2 =0.969 and SSR=0.360, R2 =0.968, respectively). The measurements were performed through the breakthrough method, on a pilot scale setup. These were featured with previous experimental work from SPT group for the same subject. After comparing both data sets, it was observed that the adsorbent had suffered ~20% degradation. Consequently, a correction factor was applied into previous values. Experimental results displayed some inconsistencies, which were attributed to the un- certainty of the correction factor and the complexity of co-adsorption mechanisms. The maxi- mum observed amount of CO2 adsorbed/kg of adsorbent was 2.25 kg.mol-1 (PCO2 =1000 Pa, T= 5ºC, RH= 84.97%), and ~2.7 mol.kg-1 after the correction factor, which is significantly close to values found in literature. The CO2 capacity under the presence of water in comparison with dry conditions (q/qdry ) was also considered to account its enhancement. At PCO2 = 40 Pa, the capacity adsorption nearly doubled in presence of high moisture content, while at the higher partial pressures (PCO2 =1000 Pa), humidity seemed to have a reduced impact. For DAC conditions, experimental trends were well characterized, which follows litera- ture remarks. Overall, the WADST and Stampi-Bombelli model represented the closest fits. In addition, an empirical model was proposed based on the observation of experimental trends. The model is described by a linear function, in which both values of slope and y-intercept were obtained through logarithmic equations.A tese visa estabelecer uma relação entre a capacidade de adsorção de CO2 e água, no contexto de captura de CO2 diretamente da atmosfera. Para tal, dados experimentais foram adquiridos dentro de um intervalo amplo de temperaturas, concentrações de CO2 e água, usando um ad- sorvente de aminas. De seguida, os dados foram ajustados a modelos mecanísticos da litera- tura e comparados. Os modelos Stampi-Bombelli e WADST foram os que melhor descreveram tendências experimentais, apresentando ajustes próximos (SSR=0.338, R2 =0.969 e SSR=0.360, R2 =0.968, respetivamente). As medições foram realizadas através do método breakthrough, numa instalação piloto de laboratório. Os valores foram complementados um trabalho experimental previamente re- alizados no grupo SPT para o mesmo tópico. Após comparar os dados, observou-se que o adsorvente sofreu uma degradação de ~20%. Consequentemente, foi aplicado um fator corre- tivo a valores anteriores. Os resultados experimentais mostraram algumas inconsistências, que por sua vez foram atribuídas à incerteza do fator de degradação e à complexidade dos mecanismos de co-adsor- ção. A quantidade máxima registada de CO2 adsorvido/kg de adsorvente foi de 2.25 kg.mol-1 (PCO2 =1000 Pa, T=5ºC, RH=84.97%), e ~2.7 mol.kg-1 após a fator corretivo, que é significativa- mente próximo da literatura. A quantidade de CO2 adsorvido em condições húmidas em rela- ção à de condições secas (q/qdry ) também foi considerada para quantificar o seu acréscimo. Nas condições de PCO2 = 40 Pa, a capacidade de adsorção quase duplicou na presença de um alto teor de água, enquanto que a níveis superiores de pressão parcial (PCO2 =1000 Pa), foi ob- servado um impacto reduzido na capacidade. Para condições DAC, as tendências foram bem caracterizadas, paralelamente a observa- ções da literatura. O modelo WADST e Stampi-Bombelli foram os que mais se aproximaram dos valores deste trabalho. Foi também proposto um modelo empírico com base em tendências experimentais. O modelo é descrito por uma função linear, cujos valores de declive e ordenada foram obtidos a partir de equações logarítmicas

Práticas artísticas no ensino básico e secundário

A educação pela arte faz-se através dos seus materiais, da sua operação, da transformação das matérias em ideias novas, em novas coisas. No seu sucesso está implicada uma literacia, uma capacidade interpretativa, ou crítica, sobre a semiosfera cada vez mais povoada, saturada de mensagens parasitárias. A educação implica uma leitura do mundo (Paulo Freire), que se projeta na interpretação de todas as camadas de expressão contemporânea, muitas vezes massificada, por vezes ainda identitária e significativa. Fala-se aqui de valorizar a identidade, exercer a pedagogia da diferença através de uma capacidade problematizadora. No seu contexto, podem exercer-se pedagogias que exploram a visão crítica do artista em interação com a escola, o artista em residência, no movimento A/ R/ Tography. Ou também exercer-se uma pedagogia triangular, centrando a arte, o contexto, a produção e a sua leitura como uma metodologia (Ana Mae Barbosa). O contexto contemporâneo é pós digital, os conteúdos não pesam nos suportes, e transmitem-se por “dentes azuis” ou redes com muitos Gs (G de Geração sem peso que sucede ao peso da aceleração gravítica). Neste campo pode delinear-se uma metodologia que alicerça o projeto ancorado nos estudos críticos sobre Cultura Visual (Fernando Hernández). Digamos que as práticas pedagógicas se cruzam em diversas direções, tacteando eficácias, expressões, capacidades, inovação. O contexto é cada vez mais voraz: a pele da cultura gosta de massagens (Kerkhove; McLuhan). A Matéria-Prima de que se fala nesta revista é aquela que devolve ao seu lugar um ponto crítico da pós modernidade: o do significante. Os sintagmas são sempre processos, e neles se formam as subjectividades, ou seja, as identidades: no desenrolar do ser, onde se produz verdadeiramente o sentido, bem junto do aqui-e-agora onde está a Matéria-Prima (Foucault).info:eu-repo/semantics/publishedVersio

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Mitochondrial physiology

As the knowledge base and importance of mitochondrial physiology to evolution, health and disease expands, the necessity for harmonizing the terminology concerning mitochondrial respiratory states and rates has become increasingly apparent. The chemiosmotic theory establishes the mechanism of energy transformation and coupling in oxidative phosphorylation. The unifying concept of the protonmotive force provides the framework for developing a consistent theoretical foundation of mitochondrial physiology and bioenergetics. We follow the latest SI guidelines and those of the International Union of Pure and Applied Chemistry (IUPAC) on terminology in physical chemistry, extended by considerations of open systems and thermodynamics of irreversible processes. The concept-driven constructive terminology incorporates the meaning of each quantity and aligns concepts and symbols with the nomenclature of classical bioenergetics. We endeavour to provide a balanced view of mitochondrial respiratory control and a critical discussion on reporting data of mitochondrial respiration in terms of metabolic flows and fluxes. Uniform standards for evaluation of respiratory states and rates will ultimately contribute to reproducibility between laboratories and thus support the development of data repositories of mitochondrial respiratory function in species, tissues, and cells. Clarity of concept and consistency of nomenclature facilitate effective transdisciplinary communication, education, and ultimately further discovery

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p&lt;0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p&lt;0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised
