Use of computational fluid dynamics in the design of bubble column reactors

Investigations into the modelling techniques that depict the transport of discrete phases (gas bubbles or solid particles) and model biochemical reactions in a bubble column reactor are discussed here. The mixture model was used to calculate gas-liquid, solid-liquid and gasliquid-solid interactions. Multiphase flow is a difficult phenomenon to capture, particularly in bubble columns where the major driving force is caused by the injection of gas bubbles. The gas bubbles cause a large density difference to occur that results in transient multi-dimensional fluid motion. Standard design procedures do not account for the transient motion, due to the simplifying assumptions of steady plug flow. Computational fluid dynamics (CFD) can assist in expanding the understanding of complex flows in bubble columns by characterising the flow phenomena for many geometrical configurations. Therefore, CFD has a role in the education of chemical and biochemical engineers, providing the examples of flow phenomena that many engineers may not experience, even through experimentation. The performance of the mixture model was investigated for three domains (plane, rectangular and cylindrical) and three flow models (laminar, k-e turbulence and the Reynolds stresses). mThis investigation raised many questions about how gas-liquid interactions are captured numerically. To answer some of these questions the analogy between thermal convection in a cavity and gas-liquid flow in bubble columns was invoked. This involved modelling the buoyant motion of air in a narrow cavity for a number of turbulence schemes. The difference in density was caused by a temperature gradient that acted across the width of the cavity. Multiple vortices were obtained when the Reynolds stresses were utilised with the addition of a basic flow profile after each time step. To implement the three-phase models an alternative mixture model was developed and compared against a commercially available mixture model for three turbulence schemes. The scheme where just the Reynolds stresses model was employed, predicted the transient motion of the fluids quite well for both mixture models. Solid-liquid and then alternative formulations of gas-liquid-solid model were compared against one another. The alternative form of the mixture model was found to perform particularly well for both gas and solid phase transport when calculating two and three-phase flow. The improvement in the solutions obtained was a result of the inclusion of the Reynolds stresses model and differences in the mixture models employed. The differences between the alternative mixture models were found in the volume fraction equation (flux and deviatoric stress tensor terms) and the viscosity formulation for the mixture phase.

University-industry-relations - their role in technological innovation:the case of biotechnology in the UK

Biotechnology is one of a series of new `generic technologies' that have been identified by western governments as possessing stategic economic opportunities. In this thesis I examine the characteristics of the technology and the government policies that have been developed to both promote and exploit the underpinning scientific research for biotechnology. The approach I have taken involves an in-depth analysis of the role of university-industry research relations in the development of biotechnology. To this end I carried out a detailed survey of biotechnology companies in the UK on the nature of their interactions and objectives. Through individual case studies of the SERC and DTI club mechanisms in biotechnology, I provide a contemporary appraisal of the development of new mechanisms involving co-ordination and cooperation between industry, government and academia, established to couple state funded science and national economic development. The public policy implications of the club funding systems for science in the UK are examined.

Technology enhanced learning in Higher Education

Technology-Enhanced Learning in Higher Education is an anthology produced by the international association, Learning in Higher Education (LiHE). LiHE, whose scope includes the activities of colleges, universities and other institutions of higher education, has been one of the leading organisations supporting a shift in the education process from a transmission-based philosophy to a student-centred, learning-based approach. Traditionally education has been envisaged as a process in which the teacher disseminates knowledge and information to the student, and directs them to perform – instructing, cajoling, encouraging them as appropriate – despite different students’ abilities. Yet higher education is currently experiencing rapid transformation, with the introduction of a broad range of technologies which have the potential to enhance student learning. This anthology draws upon the experiences of those practitioners who have been pioneering new applications of technology in higher education, highlighting not only the technologies themselves but also the impact which they have had on student learning. The anthology illustrates how new technologies – which are increasingly well-known and accepted by today’s ‘digital natives’ undertaking higher education – can be adopted and incorporated. One key conclusion is that learning remains a social process even in technology-enhanced learning contexts. So the technology-based proxies we construct need to retain and reflect the agency of the teacher. Technology-Enhanced Learning in Higher Education showcases some of the latest pedagogical technologies and their most creative, state-of-the-art applications to learning in higher education from around the world. Each of the chapters explores technology-enhanced learning in higher education in terms of either policy or practice. They contain detailed descriptions of approaches taken in very different curriculum areas, and demonstrate clearly that technology may and can enhance learning only if it is designed with the learning process of students at its core. So the use of technology in education is more linked to pedagogy than it is to bits and bytes.

A qualitative study of the impact of an educational intervention on older parents of adults with disabilities engaged in the phenomenon of future-care planning

This phenomenological study describes the impact of an educational intervention on the day-to-day experiences of older parent caregivers of adults with developmental disabilities who were engaged in the process of future-care planning. Qualitative strategies of individual and focus group interviewing were used with a purposive sample of older caregivers. Participants were members of an existing parent support group. Twenty-three caregivers representing 18 families were queried before and after the education program. The disabilities represented were mental retardation, cerebral palsy and autism. Parents whose children live at or away from home were included. The intervention was conducted on five Saturdays over a two month period; the duration of the study was five months. Findings used typical words of the respondents from their individual and focus group interviews to describe feelings, attitudes and experiences in making future-care plans. Data from verbatim transcriptions and researcher's field notes were coded, analyzed, sorted into themes, and subjected to interpretive analysis. Respondents showed a positive change in attitudes and actions after participating in the education program, regardless of their initial stage in care planning. Fears were replaced by hope and determination; hesitation and ineptitude by feelings of competence and confidence; and procrastination and delay by purposeful actions. Other key findings: use of a planning document greatly aided caregivers; barriers to planning were often intrinsic and amenable to education; residential plans were the most difficult aspect of planning; listening to the experiences of other parent caregivers was helpful; and making burial plans for their offspring was one aspect of planning parents wished to do themselves. ^

Advances in Hospitality Education: Courseware, Audiographics, and Cyberspace

Technology will play an increasingly larger role in the education of students within the hospitality curriculum. There are a significant number of emerging educational technologies aimed at changing the delivery of the entire curriculum. The development of technological platforms for multimedia instructional courseware, distance learning through audiographics, and virtual reality simulation are expected to alter and enhance the learning process while extending the boundaries of the traditional hospitality classroom.

Mitigating Social Risk in the Extractive Sector: Developing Intercultural Competence as a Tool for Negotiating Western-Indigenous Perspectives within the Undergraduate Mining Engineering Curriculum

Drawing upon critical, communications, and educational theories, this thesis develops a novel framing of the problem of social risk in the extractive sector, as it relates to the building of respectful relationships with indigenous peoples. Building upon Bakhtin’s dialogism, the thesis demonstrates the linkage of this aspect of social risk to professional education, and specifically, to the undergraduate mining engineering curriculum, and develops a framework for the development of skills related to intercultural competence in the education of mining engineers. The knowledge of social risk, as well as the level of intercultural competence, of students in the mining engineering program, is investigated through a mixture of surveys and focus groups – as is the impact of specific learning interventions. One aspect of this investigation is whether development of these attributes alters graduates’ conception of their identity as mining engineers, i.e. the range and scope of responsibilities, and understanding of to whom responsibilities are owed, and their role in building trusting relationships with communities. Survey results demonstrate that student openness to the perspectives of other cultures increases with exposure to the second year curriculum. Students became more knowledgeable about social dimensions of responsible mining, but not about cultural dimensions. Analysis of focus group data shows that students are highly motivated to improve community perspectives and acceptance. It is observed that students want to show respect for diverse peoples and communities where they will work, but they are hampered by their inability to appreciate the viewpoints of people who do not share their values. They embrace benefit sharing and environmental protection as norms, but they mistakenly conclude that opposition to mining is rooted in a lack of education rather than in cultural values. Three, sequential, threshold concepts are identified as impeding development of intercultural competence: Awareness and Acknowledgement of Different Forms of Knowledge; Recognition that Value Systems are a Function of Culture; Respect for varied perceptions of Social Wellbeing and Quality of Life. Future curriculum development in the undergraduate mining engineering program, as well as in other educational programs relevant to the extractive sector, can be effectively targeted by focusing on these threshold concepts.

The Return of Institutions. On the Latest Change in the Research on Social and Economic Development

The paper describes the latest change in the research on social and economic development of states. This change is characterized mainly by a strong emphasis put on the role of institutions as key instruments of reducing the development gap between countries. It is argued that in the years after 1989 institutions have disappeared from mainstream academia and major intellectual debates because of: (1) the widespread belief in global convergence of capitalism and (2) the modernization theory which prevailed in the social science in the 1990s. The article indicates that institutions were once again brought into focus as a result of (1) a wider debate about the institutional sources of growth and development sparked by Acemoglu and Robinson’s Why Nations Fail, (2) the beginning of the global economic crisis of 2008 triggered by the fall of American investment bank Lehman Brothers (3) diversified consequences of the economic crisis seen all over Europe and the USA which illustrate (4) the institutional varieties of capitalism.

Proposal for Academic Achievement and Permanence of Students in the 7th Grade (1)

This paper analyzes the impact of change processes experienced by many student populations when completing primary education (1st-6th grade) and starting secondary education (7th-11th grade). Based on the research conducted, this paper describes situations and aspects that may result in conditional factors for the student’s adjustment at this level: time-space changes, as well as organizational and dynamic changes that would set the new educational environment and social context in which this new stage will be developed. Such conditional factors that affect learning in incoming students: programs, teaching methodology, learning styles and new evaluation methods will be discussed. As a result of this research, a proposal is presented to facilitate transition from primary to the secondary education. This proposal includes guidelines for awareness and strengthening of pedagogical mediation, which would contribute to the permanence of students from all types of institutions in the education system.  (1) [Translator’s note: The Costa Rican education system is composed of primary education (1st-6th grade) and secondary education (7th-11th grade).]

Strategies to Promote Research and Logical Reasoning in the Teaching of Mathematics in the Schools

The purpose of this paper is to raise a debate on the urgent need for teachers to generate innovative situations in the teaching-learning process, in the field of Mathematics, as a way for students to develop logical reasoning and research skills applicable to everyday situations. It includes some statistical data and possible reasons for the poor performance and dissatisfaction of students towards Mathematics. Since teachers are called to offer meaningful and functional learning experiences to students, in order to promote the pleasure of learning, teacher training should include experiences that can be put into practice by teachers in the education centers. This paper includes a work proposal for Mathematics Teaching to generate discussion, curiosity and logical reasoning in students, together with the Mathematical problem solving study.

Teacher’s Role in the Promotion of Two Emotional Intelligence Competencies in Fifth-Grade Children

This paper presents the results of a qualitative study aimed at analyzing the teacher’s role in promoting awareness and management of emotions in fifth-graders, as competencies of emotional intelligence. This resulted in a very significant study since, from the psychopedagogic perspective, it aims at breaking with the traditional role of teachers exclusively focused on transmitting knowledge, leaving aside the much-needed emotional support. Children demonstrated a poor vocabulary, as well as difficulty to identify some emotions and differentiate between them. This means a limitation for children to be aware of their own emotions and to control them.  As a conclusion, it is important to maximize the emotional capacities of students; it should be a primary task in the education centers, where teachers play a key role as a model and as a promoter of emotional intelligence.

Classificação de sons cardíacos usando Motifs: desenvolvimento de uma aplicação móvel

Este documento foi redigido no âmbito da Tese, do Mestrado em Engenharia Informática na área de Tecnologias do Conhecimento e Decisão, do Departamento de Engenharia Informática, do ISEP, cujo tema é classificação de sons cardíacos usando motifs. Neste trabalho, apresenta-se um algoritmo de classificação de sons cardíacos, capaz de identificar patologias cardíacas. A classificação do som cardíaco é um trabalho desafiante dada a dificuldade em separar os sons ambiente (vozes, respiração, contacto do microfone com superfícies como pele ou tecidos) ou de ruído dos batimentos cardíacos. Esta abordagem seguiu a metodologia de descoberta de padrões SAX (motifs) mais frequentes, em séries temporais relacionando-os com a ocorrência sistólica (S1) e a ocorrência diastólica (S2) do coração. A metodologia seguida mostrou-se eficaz a distinguir sons normais de sons correspondentes a patologia. Os resultados foram publicados na conferência internacional IDEAS’14 [Oliveira, 2014], em Julho deste ano. Numa fase seguinte, desenvolveu-se uma aplicação móvel, capaz de captar os batimentos cardíacos, de os tratar e os classificar. A classificação dos sons é feita usando o método referido no parágrafo anterior. A aplicação móvel, depois de tratar os sons, envia-os para um servidor, onde o programa de classificação é executado, e recebe a resposta da classificação. É também descrita a arquitetura aplicacional desenhada e as componentes que a constituem, as ferramentas e tecnologias utilizadas.

Diagnóstico cardíaco a partir de dados acústicos e clínicos

Este documento foi redigido no âmbito da dissertação do Mestrado em Engenharia Informática na área de Arquiteturas, Sistemas e Redes, do Departamento de Engenharia Informática, do ISEP, cujo tema é diagnóstico cardíaco a partir de dados acústicos e clínicos. O objetivo deste trabalho é produzir um método que permita diagnosticar automaticamente patologias cardíacas utilizando técnicas de classificação de data mining. Foram utilizados dois tipos de dados: sons cardíacos gravados em ambiente hospitalar e dados clínicos. Numa primeira fase, exploraram-se os sons cardíacos usando uma abordagem baseada em motifs. Numa segunda fase, utilizamos os dados clínicos anotados dos pacientes. Numa terceira fase, avaliamos a combinação das duas abordagens. Na avaliação experimental os modelos baseados em motifs obtiveram melhores resultados do que os construídos a partir dos dados clínicos. A combinação das abordagens mostrou poder ser vantajosa em situações pontuais.
