Características do gás durante a gasificação de biomassa em leito fluidizado

Durante os últimos anos, a procura mundial de recursos energéticos renováveis tem sofrido um grande aumento. Neste grupo insere-se a biomassa, cuja conversão termoquímica, principalmente através de tecnologias de combustão e gasificação, é utilizada para a produção de energia térmica e elétrica. No processo de gasificação de biomassa é possível obter um combustível gasoso secundário com variadas aplicações, podendo inclusive servir como substituto do gás natural. No entanto, ao contrário da combustão, esta tecnologia aplicada à biomassa ainda está em fase de demonstração a nível industrial, apresentando algumas limitações em alguns aspetos tecnológicos, entre os quais a qualidade do gás produzido. Neste contexto, e com o objetivo de contribuir para o conhecimento da aplicabilidade desta tecnologia, surge o presente trabalho, onde a caracterização e definição das condições de operação de um gasificador de biomassa, bem como a caracterização do gás produzido foram objeto de estudo. Foi realizado um conjunto de experiências de gasificação direta, num reator de leito fluidizado borbulhante à escala piloto, com dois tipos de biomassa tipicamente encontrados em Portugal, e para diferentes condições de operação do gasificador, nomeadamente no que diz respeito à razão de equivalência. A biomassa utilizada consistiu em pellets comerciais de madeira e estilha de biomassa florestal residual derivada de pinheiro (Pinus pinaster), e resultante de operações florestais em Portugal. Na gama de temperatura do leito aplicada, tipicamente entre 800ºC e 875ºC, o reator funcionou em condições auto térmicas, isto é, sem a necessidade de recorrer a uma fonte de calor auxiliar externa. Em relação à composição do gás seco durante o processo de gasificação, os gases presentes em maior percentagem (em volume), para as experiências com ambos os tipos de biomassa, são o CO2 e o CO, com o primeiro a registar valores médios entre os 13.4% e os 16%, e o segundo entre 11.3% e 16.3%. Por ordem decrescente de concentração encontra-se o H2, na gama de 5.8% a 12.7%, o CH4 com valores médios entre 2.8% e 4.5%, e o C2H4 com concentrações médias entre 1.0% e 2.2%. Importa referir ainda a ausência de O2 no gás produzido. Verificou-se na concentração de H2, a principal diferença na composição do gás seco relativamente à gasificação dos dois combustíveis utilizados, com valores de concentração inferiores durante a operação com estilha de biomassa florestal residual derivada de pinheiro. Nas várias experiências realizadas, e para as condições operatórias utilizadas, observou-se que a razão de equivalência (RE) exerce um efeito significativo na composição do gás, verificando-se, genericamente, que com o aumento da RE a concentração de gases combustíveis diminui. Os valores de Poder Calorífico Inferior (PCI) obtidos para o gás seco produzido encontram-se na gama 3.4-5.6 MJ/Nm3, sendo que os valores mais elevados foram registados no decorrer dos ensaios de gasificação com pellets de madeira. Para ambos os combustíveis, o PCI do gás seco diminui com o aumento da RE.

Self-management of coronary heart disease in angina patients after percutaneous coronary intervention: A mixed methods study.

After having elective percutaneous coronary intervention (PCI) patients are expected to self-manage their coronary heart disease (CHD) by modifying their risk factors, adhering to medication and effectively managing any recurring angina symptoms but that may be ineffective. Objective: Explore how patients self-manage their coronary heart disease (CHD) after elective PCI and identify any factors that may infl uence that. Design and method: This mixed methods study recruited a convenience sample of patients (n=93) approximately three months after elective PCI. Quantitative data were collected using a survey and were subject to univariate, bivariate and multi-variate analysis. Qualitative data from participant interviews was analysed using thematic analysis. Findings: After PCI, 74% of participants managed their angina symptoms inappropriately. Younger participants and those with threatening perceptions of their CHD were more likely to know how to effectively manage their angina symptoms. Few patients adopted a healthier lifestyle after PCI. Qualitative analysis revealed that intentional non-adherence to some medicines was an issue. Some participants felt unsupported by healthcare providers and social networks in relation to their self-management. Participants reported strong emotional responses to CHD and this had a detrimental effect on their self-management. Few patients accessed cardiac rehabilitation.

The role of microRNA 21 in the development of in-stent restenosis

Coronary heart disease is a major cause of morbidity and mortality worldwide. Percutaneous coronary intervention (PCI) has become the most widely used method of coronary artery revascularisation. The use of stents to hold open atherosclerosis induced arterial narrowing has significantly reduced elastic recoil and acute vessel occlusion following balloon angioplasty. However, bare metal stents have been associated with in-stent restenosis attributed to vascular smooth muscle cell (VSMC) hyperplasia and excessive neointimal formation. The resultant luminal renarrowing may manifest clinically with the return of symptoms such as chest pain or shortness of breath. The development of drug eluting stents has significantly reduced the incidence of in-stent restenosis (ISR). Unfortunately the antiproliferative medications used not only inhibit VSMC proliferation but also re-endothelialisation of the stented vessel. In addition, the drug impregnated polymer coating has been associated with a chronic inflammatory response within the vessel wall predisposing patients to stent thrombosis. Thus the identification of novel therapies which promote vessel healing without excessive proliferative or inflammatory response may improve long term outcome and reduce the need for repeated revascularisation. MicroRNAs (miRs) are short (18-25 nucleotide) non-coding RNAs acting to regulate gene expression. By binding to the 3’untranslated region of mRNA they act to fine tune gene expression either by mRNA degradation or translational repression. Originally identified in coordinating tissue development microRNAs have also been shown to play important roles coordinating the inflammatory response and in numerous cardiovascular diseases. MiR-21 has been identified in human atherosclerotic plaques, arteriosclerosis obliterans and abdominal aortic aneurysms. In addition, its up regulation has been documented in preclinical models of vascular injury. This study sought to identify the role of miR-21 in the development of ISR. Utilising a small animal model of stenting and in vitro techniques, we sought to investigate its influence upon VSMC and immune cell response following stenting. 19 The refinement of a murine stenting model within the Baker laboratory and the electrochemical dissolution of the metal stent from within harvested vascular tissues significantly improved the ability to perform detailed histological analysis. In addition, identification of miRNAs using in situ hybridisation was achieved for the first time within stented tissue. Neointimal formation and ISR was significantly reduced in mice in which miR-21 had been genetically deleted. In addition, neointimal composition was found to be altered in miR-21 KO mice with reductions in VSMC and elastin content demonstrated. Importantly, no difference in re-endothelialisation was observed. In vitro analysis demonstrated that VSMCs from miR-21 KO mice had both reduced proliferative and migratory capacity following platelet derived growth factor stimulation. Molecular analysis revealed that these differences may, at least in part, be due to de-repression of programmed cell death 4 (PDCD4). PDCD4 is a known miR-21 target within VSMCs implicated in the suppression of proliferation and promotion of apoptosis. Unfortunately, initial attempts at antimiR mediated knockdown of miR-21 in vivo, failed to produce a similar change in the suppression of ISR. Furthermore, a significant alteration in macrophage polarisation state within the neointima of miR-21 WT and KO mice was noted. Immunohistochemical staining revealed a preponderance of anti-inflammatory M2 macrophages in KO mice. Analysis of bone marrow derived macrophages from miR-21 KO mice demonstrated an increased level of the peroxisome proliferation activating receptor-γ (PPARγ) which facilitates M2 polarisation. Importantly, significant alterations in numerous pro-inflammatory cytokines, which also have mitogenic effects, were also found following genetic deletion of miR-21. In Summary, this is the first study to look at miRs in the development of ISR. MiR-21 plays an important role in the development of ISR by influencing the proliferative response of VSMCs and modulating the immune response following stent deployment. Further attempts to modulate miR-21 expression following PCI may reduce ISR and the need for repeat revascularisation while also reducing the risk of stent thrombosis.

Características de cinzas e sua aplicação no tratamento de gases durante a gasificação de biomassa

Na procura de melhores combustíveis para a produção de energia térmica e energia elétrica, a biomassa apresenta-se como uma das fontes de energia renováveis menos prejudiciais ao meio ambiente, esta é considerada como um recurso neutro do ponto de vista de emissões de dióxido de carbono. Atualmente, a tecnologia predominante no domínio da conversão energética de biomassa por via termoquímica é a combustão. Contudo, verifica-se a procura de combustíveis de melhor qualidade produzidos a partir de biomassa, como por exemplo na forma gasosa (gás de combustível). A produção deste tipo de combustíveis gasosos envolvendo processos de gasificação carece do desenvolvimento de tecnologia que permita obter um gás combustível com características adequadas às utilizações pretendidas. Os problemas mais relevantes relacionados com a conversão termoquímica da biomassa incluem a produção de cinzas e de alcatrões, estes podem levar a vários problemas operatórios. O presente trabalho teve dois objetivos, a caracterização das cinzas resultantes do processo de combustão de biomassa e o estudo do efeito da aplicação das cinzas para melhorar as propriedades do gás produzido durante o processo de gasificação de biomassa, principalmente na redução de compostos condensáveis (alcatrões). As cinzas volantes da combustão de biomassa analisadas apresentam na sua constituição elementos químicos característicos da biomassa, onde o cálcio apresenta-se em concentrações mais elevadas. Em menores concentrações encontram-se sódio, magnésio, fósforo, enxofre, cloro, potássio, manganês e ferro. As cinzas de fundo, pelo contributo que a areia do leito tem, são caracterizadas por conterem grandes concentrações de silício. Durante os processos de gasificação de biomassa a concentração de compostos condensáveis diminuiu com o aumento da razão de equivalência. As cinzas, colocadas no reator de leito fixo, apresentam um efeito positivo sobre a qualidade do gás, nomeadamente um aumento de 47,8% no teor de H2 e de 11% de CO, consequentemente obteve-se um gás combustível com PCI (poder calorífico inferior) mais elevado.

Intervencionismo coronario percutáneo en Navarra: resultados de un centro de bajo volumen intervencionista

Fundamento. El intervencionismo coronario percutáneo (PCI) es una opción terapéutica fundamental en pacientes con enfermedad coronaria. Para realizarla los especialistas deben formarse y acreditarse. Se sabe que el número de procedimientos realizados al año influye en los resultados. Pretendemos mostrar que con un bajo volumen de PCI algunos centros obtienen buenos resultados. Método. Análisis prospectivo de las características clínicas y resultados inmediatos obtenidos en nuestro centro con el PCI entre 2006 y 2012 y análisis retrospectivo de la supervivencia global, supervivencia libre de eventos y reestenosis de los PCI realizados entre 2006 y 2009. Se compararon las características clínicas, los eventos agudos y a largo plazo (complicaciones, supervivencia y mortalidad) entre nuestros pacientes y los de algunos trabajos publicados. Resultados. Nuestra probabilidad de tener cualquier complicación en un PCI fue del 9% con una mortalidad global del 2%. La mortalidad del PCI en situación estable fue del 0,43% y en el síndrome coronario agudo del 6,25%. Las complicaciones en el lugar del acceso vascular fueron del 1,44% y la incidencia de reestenosis a los nueve meses, en pacientes sometidos por primera vez a PCI, fue del 5,2%. Conclusiones. Aunque el alto volumen intervencionista ha demostrado ser importante para tener una baja tasa de complicaciones y una buena evolución a largo plazo, hay centros con bajo volumen intervencionista que por sus características pueden obtener resultados equiparables a los de alto volumen.

Cortisol Reactivity and Observed Parenting among Mothers of Children with and without ADHD

Parenting is a robust predictor of developmental outcomes among children with ADHD. Early parenting predicts the persistence and course of ADHD and comorbid problems above and beyond risk associated with shared genetic effects. Yet, on average, mothers of children with ADHD are less positive and more negative in their parent-child interactions compared to mothers of non-disordered children. Little is known about psychobiological markers which may be associated with individual variations in maternal parenting in families of children with ADHD. Neurobiological models of parenting suggest that maternal cortisol levels following a stressor may be positively associated with hostile and intrusive parenting; however, to date no studies have examined maternal cortisol reactivity and parenting in school-age, or clinical samples of, children. Mothers’ regulation of physiological stress responses may be particularly important for families of children with ADHD, as parenting a child with chronically challenging behaviors represents a persistent environmental stressor. The current study sought to extend the existing literature by providing an empirical examination of the relationship between maternal cortisol reactivity following two laboratory stressors and parenting among mothers of children with and without ADHD. It was hypothesized that child ADHD group would moderate the relationship between cortisol reactivity and self-reported and observed parenting. Greater total cortisol output and greater increase in cortisol during the TSST were associated with decreased positive parenting and increased negative and directive parenting, with the exception of parental involvement, which was associated with increased cortisol output during the TSST. Conversely, cortisol output during the PCI was associated with increased positive parenting, increased parental involvement, and decreased negative parenting. In contrast to the TSST, a greater decrease in cortisol during the PCI indicated more positive parenting and parental involvement. These associations were specific to mothers of children with ADHD, with the exception of maternal directiveness, which was specific to comparison mothers. Findings add to our understanding of physiological processes associated with maternal parenting and contribute to an integrative biological, psychological, and cognitive process model of parenting in families of children with ADHD.

Os museus e o património cultural imaterial: Estratégias para o desenvolvimento de boa práticas

omando como referência fundamental o trabalho desenvolvido pela UNESCO em matéria de proteção do Património Cultural Imaterial (PCI), muito particularmente a Convenção para a Salvaguarda do Património Cultural Imaterial (2003), considerou-se oportuno refletir sobre as implicações que este enfoque traz para os museus. São indiscutíveis as repercussões que este instrumento trouxe para o reconhecimento da importância do PCI à escala internacional, motivando um crescendo de iniciativas em tomo da sua salvaguarda. São vários os agentes envolvidos na preservação deste património, no entanto o International Council of Museums (ICOM) reconhece um papel central aos museus nesta matéria. Mas para responder a este repto, os museus terão que repensar as suas estratégias de forma a relacionar-se mais com o PCI, contrariando uma longa tradição profundamente enraizada na cultura material. O presente estudo reflete sobre as possibilidades de actuação dos museus no sentido de dar resposta aos desafios da Convenção 2003, sendo certo que a partir das catividades dos museus é possível encontrar formas de estudar e de dar visibilidade a este património. Em função das especificidades de cada museu, podem ser encontradas estratégias de salvaguarda do PCI, entre as quais se pode incluir o inventário e a documentação (audiovisual, texto, áudio, imagem), a investigação, a divulgação através de exposições e publicações, difusão através da internet, educação não formal, entre outras actividades. Alguns museus começaram já a desenvolver abordagens integradas para a salvaguarda do PCI, cujos exemplos se apresentam. Este tema suscita vários desafios, implicando práticas museológicas inovadoras que possam reflectir o papel dos museus como promotores da diversidade e criatividade cultural. ABSTRACT: Recalling the UNESCO's work towards the protection of Intangible Cultural Heritage (ICH), in particular the Convention for the Safeguarding of the Intangible Cultural Heritage adopted in 2003, I took this opportunity to reflect upon the implications that this recognition brings to museums. The overwhelming success of this document has raised the importance of ICH at international level, motivating a growing number of initiatives towards its safeguard. Accordingly, to the 2003 Convention, there are many agents involved in the preservation of this heritage, yet the International Council of Museums (ICOM) recognizes a central role for museums. Nevertheless, to face this challenge, museums will have to rethink their relationship with ICH in opposition to their deep rooted tradition in material culture. The present study reflects upon the possibilities that museums have to answer the changeling 2003 Convention, recognizing that it’s possible through museum activities to find ways to study and give visibility to ICH. According to each museum specificities, it seems clear that strategies can be engaged in order to promote the safeguard of ICH, including inventory and documentation (audiovisual, audio, text and image), research, promotion through exhibitions, publications, dissemination trough internet and other means, informal education, among other activities. Many museums have already started exploring integrated approaches towards the safeguard of ICH and some of these examples are presented in this study. This theme is challenging, implying innovative museum practices which reflect on museums role towards the promotion of cultural diversity and creativity.

Desenvolvimento de uma unidade pirolítica com reator de cilindro rotativo: obtenção de bio-óleo

The demand for alternative sources of energy drives the technological development so that many fuels and energy conversion processes before judged as inadequate or even non-viable, are now competing fuels and so-called traditional processes. Thus, biomass plays an important role and is considered one of the sources of renewable energy most important of our planet. Biomass accounts for 29.2% of all renewable energy sources. The share of biomass energy from Brazil in the OIE is 13.6%, well above the world average of participation. Various types of pyrolysis processes have been studied in recent years, highlighting the process of fast pyrolysis of biomass to obtain bio-oil. The continuous fast pyrolysis, the most investigated and improved are the fluidized bed and ablative, but is being studied and developed other types in order to obtain Bio-oil a better quality, higher productivity, lower energy consumption, increased stability and process reliability and lower production cost. The stability of the product bio-oil is fundamental to designing consumer devices such as burners, engines and turbines. This study was motivated to produce Bio-oil, through the conversion of plant biomass or the use of its industrial and agricultural waste, presenting an alternative proposal for thermochemical pyrolysis process, taking advantage of particle dynamics in the rotating bed that favors the right gas-solid contact and heat transfer and mass. The pyrolyser designed to operate in a continuous process, a feeder containing two stages, a divisive system of biomass integrated with a tab of coal fines and a system of condensing steam pyrolytic. The prototype has been tested with sawdust, using a complete experimental design on two levels to investigate the sensitivity of factors: the process temperature, gas flow drag and spin speed compared to the mass yield of bio-oil. The best result was obtained in the condition of 570 oC, 25 Hz and 200 cm3/min, temperature being the parameter of greatest significance. The mass balance of the elementary stages presented in the order of 20% and 37% liquid pyrolytic carbon. We determined the properties of liquid and solid products of pyrolysis as density, viscosity, pH, PCI, and the composition characterized by chemical analysis, revealing the composition and properties of a Bio-oil.

Gender differences in presentation, coronary intervention, and outcomes of 28,985 acute coronary syndrome patients in Victoria, Australia

BACKGROUND: Differences in demographics, presenting characteristics, and treatment of heart disease in women may contribute to adverse outcomes. The purpose of this paper was to describe gender differences in the epidemiology, treatment, and outcomes of all admissions for acute coronary syndrome (ACS) in Victoria that occurred between June 2007 and July 2009. METHODS: We undertook a retrospective cohort study of all patients admitted to Victorian hospitals with a first time diagnosis of ACS. Use of angiograms, percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), and adverse outcomes (death and/or unplanned readmission) were compared by gender and hierarchical logistic regression models were used to account for confounding variables. RESULTS: Of a total of 28,985 ACS patients, 10,455 (36%) were women. Compared with men, women were older (aged ≥75 years: 54% vs 31%; p < .001), more likely to present with multiple comorbidities (>1 comorbidity: 53% vs 46%; p < .001), and more likely to be diagnosed with non-ST-segment elevation ACS (86% vs 80%; p < .001). Women were less likely to receive coronary interventions (angiogram: adjusted odds ratio [aOR], 0.71; 95% CI, 0.66-0.75; PCI: aOR, 0.73; 95% CI, 0.66-0.80; CABG: aOR, 0.58; 95% CI, 0.53-0.64). Adverse outcomes were similar in women and men after accounting for confounding variables. CONCLUSIONS: Our results show that women in Victoria were less likely to receive coronary interventions after an admission for ACS. Clinicians should be wary of inherent gender bias in decisions to refer patients for angiography.

Process capability estimation for leukocyte filtering process in blood service: a comparison study

This article considers a comparison study between different non-normal process capability estimation methods and utilizing themin the leukocyte filtering process in blood service sectors. Since the amount of leukocyte in a unit of the blood is a critical issue inthe blood transfusion process and patient safety, estimating and monitoring the capability of the leukocyte filtering process to meetthe target window is very important for blood service sectors. However, observed data from the leukocyte filtering process showthat the leukocyte levels after filtering demonstrate a right skewed distribution and applying conventional methods with a normalityassumption fails to provide trustful results. Hence, we first conduct a simulation study to compare different methods in estimating theprocess capability index of non-normal processes and then we apply these techniques to obtain the process capability of the leukocytefiltering process. The study reveals that the Box-Cox transformation method provides reliable estimation of the process capability ofthe leukocyte filtering process.

The Effects of Age, Ethnicity, Sexual Dysfunction, Urinary Incontinence, Masculinity, and Relationship with the Partner on the Quality of Life of Men with Prostate Cancer

Prostate cancer, the leading cause of cancer in men, has positive survival rates and constitutes a challenge to men with its side effects. Studies have addressed the bivaritate relationships between prostate cancer treatment side effects masculinity, partner relationship, and quality of life (QOL). However, few studies have highlighted the relationships among prostate cancer treatment side effects (i.e., sexual dysfunction, urinary incontinence), masculinity, and relationship with the partner together on QOL in men. Most studies were conducted with predominately Caucasian sample of men. Miami is a unique multiethnic setting that hosts Cuban, Columbian, Venezuelan, Haitian, other Latin American and Caribbean communities that were not represented in previous literature. The purpose of this study was to examine relative contributions of age, ethnicity, sexual dysfunction, urinary incontinence, masculinity, and perception of the relationship with the partner on the quality of life in men diagnosed with prostate cancer. Data were collected using self administered questionnaires measuring demographic variables, sexual and urinary functioning (UCLA PCI), masculinity (CMNI), partner relationship (DAS), and QOL (SF-36). A total of 117 partnered heterosexual men diagnosed with prostate cancer were recruited from four urology clinics in Miami, Florida. Men were 67.47 (SD = 8.42) years old and identified themselves to be of Hispanic origin (54.3 %, n = 63). Findings demonstrated that there was a significant moderate negative relationship between urinary and sexual functioning of men. There was a significant strong negative association between men’s perceived relationship with partner and masculinity. There was a weak negative relationship between the partner relationship and QOL. Hierarchal multiple regression showed that the partner relationship (β = -.25, t (91) = -2.28, p = .03) significantly contributed overall to QOL. These findings highlight the importance of the relationship satisfaction in the QOL of men with prostate cancer. Nursing interventions to enhance QOL for these men should consider strengthening the relationship and involving the female partner as an active participant.

A transformation technique to estimate the process capability index for non-normal processes

Estimating the process capability index (PCI) for non-normal processes has been discussed by many researches. There are two basic approaches to estimating the PCI for non-normal processes. The first commonly used approach is to transform the non-normal data into normal data using transformation techniques and then use a conventional normal method to estimate the PCI for transformed data. This is a straightforward approach and is easy to deploy. The alternate approach is to use non-normal percentiles to calculate the PCI. The latter approach is not easy to implement and a deviation in estimating the distribution of the process may affect the efficacy of the estimated PCI. The aim of this paper is to estimate the PCI for non-normal processes using a transformation technique called root transformation. The efficacy of the proposed technique is assessed by conducting a simulation study using gamma, Weibull, and beta distributions. The root transformation technique is used to estimate the PCI for each set of simulated data. These results are then compared with the PCI obtained using exact percentiles and the Box-Cox method. Finally, a case study based on real-world data is presented.

Process capability analysis in non normal linear regression profiles

When the distribution of a process characterized by a profile is non normal, process capability analysis using normal assumption often leads to erroneous interpretations of the process performance. Profile monitoring is a relatively new set of techniques in quality control that is used in situations where the state of product or process is represented by a function of two or more quality characteristics. Such profiles can be modeled using linear or nonlinear regression models. In some applications, it is assumed that the quality characteristics follow a normal distribution; however, in certain applications this assumption may fail to hold and may yield misleading results. In this article, we consider process capability analysis of non normal linear profiles. We investigate and compare five methods to estimate non normal process capability index (PCI) in profiles. In three of the methods, an estimation of the cumulative distribution function (cdf) of the process is required to analyze process capability in profiles. In order to estimate cdf of the process, we use a Burr XII distribution as well as empirical distributions. However, the resulted PCI with estimating cdf of the process is sometimes far from its true value. So, here we apply artificial neural network with supervised learning which allows the estimation of PCIs in profiles without the need to estimate cdf of the process. Box-Cox transformation technique is also developed to deal with non normal situations. Finally, a comparison study is performed through the simulation of Gamma, Weibull, Lognormal, Beta and student-t data.
