Influence of Angle of Air Injection and Particles in Bed Hydrodynamics of Swirling Fluidized Bed

The thesis presented here unveils an experimental study of the hydrodynamic characteristics of swirling fluidized bed viz. pressure drop across the distributor and the bed, minimum fluidizing velocity, bed behaviour and angle of air injection. In swirling fluidized bed the air is admitted to the bed at an angle 'Ѳ' to the horizontal. The vertical component of the velocity v sin Ѳ causes fluidization and the horizontal component v cos Ѳ contributes to swirl motion of the bed material.The study was conducted using spherical particles having sizes 3.2 mm, 5.5 mm & 7.4 mm as the bed materials. Each of these particles was made from high density polyethylene, nylon and acetal having relative densities of 0.93, 1.05 and 1.47 respectively.The experiments were conducted using conidour type distributors having four rows of slits. Altogether four distributors having angles of air injection (Φ)- 0°, 5°, 10° & 15° were designed and fabricated for the study. The total number of slits in each distributor was 144. The area of opening was 6220 mm2 making the percentage area of opening to 9.17. But the percentage useful area of opening of the distributor was 96.The experiments on the variation of distributor pressure drop with superficial velocity revealed that the distributor pressure drop decreases with angle of air injection. Investigations related to bed hydrodynamics were conducted using 2.5 kg of bed material. The bed pressure drop measurements were made along the radial direction of the distributor at distances of 60 mm, 90 mm, 120 mm & 150 mm from the centre of the distributor. It was noticed that after attaining minimum fluidizing velocity, the bed pressure drop increases along the radial direction of the distributor. But at a radial distance of 90 mm from the distributor centre, after attaining minimum fluidizing velocity the bed pressure drop remains almost constant. It was also observed that the bed pressure drop varies inversely with particle size as well as particle density.An attempt was made to determine the effect of various parameters on minimum fluidizing velocity. It was noticed that the minimum fluidizing velocity varies directly with angle of air injection (Φ), particle size and particle density.The study on the bed behaviour showed that the superficial velocity required for initiating various bed phenomena (such as swirl motion and separation of particles from the cone at the centre) increase with increase in particle size as well as particle density. It was also observed that the particle size and particle density directly influence the superficial velocity required for various regimes of bed behaviour such as linear variation of bed pressure drop, constant bed pressure drop and sudden increase or decrease in bed pressure drop.Experiments were also performed to study the effect of angle of air injection (Φ). It was noticed that the bed pressure drop decreases with angle of air injection. It was also noticed that the angle of air injection directly influence the superficial velocity required for initiating various bed phenomena as well as the various regimes of bed behaviour.

The recognition of rights to same-sex couples: the path towards a pluralistic concept of family

This paper presents the final results of the research project undertaken in 2010 and 2011 by the legal research group “Filius”, affiliated with Corporación Universitaria Empresarial Alexander von Humboldt of Armenia, (Quindío). The project’s general objective is “to establish the concept of family used by the Colombian legal system based on the judgments of the Constitutional Court granting rights to same-sex couples”. To this end, a line of jurisprudence was developed from the Court’s rulings that discussed the rights of same-sex couples, concluding that despite the great progress made in Colombia on the recognition of rights to these couples following Decision C-075/2007, in all these judgments the Court had always refused to recognize their family status, and it was not until 2011, in Decision C-577, that the Court accepted that same-sex couples constitute a family, thereby dramatically changing the constitutional doctrine that had maintained the criteria of heterosexuality as defining family.

The main contours of Richard S. Peters's concept of moral education.

Exponer de modo sistemático las ideas que la autora considera imprescindibles para comprender el concepto de la educación moral de Richard Stanley Peters . En el primer capítulo se ofrece el perfil de Peters y una visión general sobre la educación moral y sus obras. Los tres capítulos siguientes presentan 'el mapa' de su pensamiento. Concretamente, la exposición se desarrolla en torno a cuatro aspectos o utilizando la terminología de Peters, se refiere a estos aspectos como 'signposts'. El capítulo segundo está dedicado a la finalidad de la educación moral y el tercero al educando y su desarrollo. Los otros dos aspectos, -el contenido y los procesos, están tratados en el capítulo cuatro. Al final de la exposición y a modo de conclusión, la autora ofrece algunas valoraciones de las contribuciones de Peters. Una síntesis de las conclusiones se puede expresar en la siguiente fórmula: los aspectos que Peters cuestiona respecto a algunos planteamientos más influenciados por Kant tienen validez. Sin embargo, la solución que propone se puede decir que queda a 'mitad del camino' porque al final, Peters no consiguió superar del todo los reduccionismos que caracterizan los puntos de vista que él pretendió armonizar. Este fracaso está vinculado al método de la filosofía analítica.

Must the concept of the State be divided? : political and ethical challenges

Este artigo analisa a medida em que algumas discussões recentes na teoria política e social têm sido bem sucedidas em fornecer discursos que legitimam a ruptura de fronteiras nacionais/estatais (internas e externas). Isto está claramente evidente na Europa de hoje, uma Europa mista de estados grandes e pequenos. Duas das mais publicamente disseminadas discussões incluem por um lado o debate tão familiar sobre a globalização e por outro a própria teoria política, onde os temas são ou controvérsias sobre o nacionalismo e autodeterminação, ou o multiculturalismo, os direitos de grupos, a chamada política da diferença e a noção emergente da sociedade civil e associações civis.

On the concept of the public: the local museums’ case

Globally, the public is understood as the whole of a service’s users. In the specific case of the museums, the users are all those who make use of the service offered by the museum institution. Thus, the museum’s public corresponds not only to the visitors (people who enter or have entered the museum), but also to the part of those who, in some way, with no relationship of presence within the museum, have enjoyed the services or property made available by it (for instance the ordering of books or other material by catalogue, visit to travelling exhibitions, end users of pedagogical actions carried out in schools…) On the other hand, when we refer to the public, it is necessary to make another distinction: between the real or effective public and the potential public. The former is the group of individuals who have visited or have used the museum, while in the second case are included all the people who, due to their specific characteristics, are susceptible to become the real or effective public.

Museums and quality, from the concept of the museum that carries out functions to the museum that provides services

Quality management Self-evaluation of the organisation Citizens/customers satisfaction Impact on society evaluation Key performance evaluation Good practices comparison (Benchmarking) Continuous improvement In professional environments, when quality assessment of museums is discussed, one immediately thinks of the honourableness of the directors and curators, the erudition and specialisation of knowledge, the diversity of the gathered material and study of the collections, the collections conservation methods and environmental control, the regularity and notoriety of the exhibitions and artists, the building’s architecture and site, the recreation of environments, the museographic equipment design. We admit that the roles and attributes listed above can contribute to the definition of a specificity of museological good practice within a hierarchised functional perspective (the museum functions) and for the classification of museums according to a scale, validated between peers, based on “installed” appreciation criteria, enforced from above downwards, according to the “prestige” of the products and of those who conceive them, but that say nothing about the effective satisfaction of the citizen/customers and the real impact on society. There is a lack of evaluation instruments that would give us a return of all that the museum is and represents in contemporary society, focused on being and on the relation with the other, in detriment of the ostentatious possession and of the doing in order to meet one’s duties. But it is only possible to evaluate something by measurement and comparison, on the basis of well defined criteria, from a common grid, implicating all of the actors in the self-evaluation, in the definition of the aims to fulfil and in the obtaining of results.

Reflections on the concept of the central executive

Notes that the central executive lies at the heart of A. D. Baddeley's theory of working memory, but that what it does has been characterized in several different ways. This chapter reviews and brings together various interpretations of central executive functioning. The authors describe an experiment involving a novel cognitive task to point out the restrictive nature of the term 'executive capacity.' The chapter concludes by commenting briefly on the implications of a working memory model in which the executive does not play a major part.
