An interdisciplinary approach to designing and evaluating a hybrid solar-biomass power plant

Purpose: Energy security is a major concern for India and many rural areas remain un-electrified. Thus, innovations in sustainable technologies to provide energy services are required. Biomass and solar energy in particular are resources that are widely available and underutilised in India. This paper aims to provide an overview of a methodology that was developed for designing and assessing the feasibility of a hybrid solar-biomass power plant in Gujarat. Design/methodology/approach: The methodology described is a combination of engineering and business management studies used to evaluate and design solar thermal collectors for specific applications and locations. For the scenario of a hybrid plant, the methodology involved: the analytical hierarchy process, for solar thermal technology selection; a cost-exergy approach, for design optimisation; quality function deployment, for designing and evaluating a novel collector - termed the elevation linear Fresnel reflector (ELFR); and case study simulations, for analysing alternative hybrid plant configurations. Findings: The paper recommended that for a hybrid plant in Gujarat, a linear Fresnel reflector of 14,000 m2 aperture is integrated with a 3 tonne per hour biomass boiler, generating 815 MWh per annum of electricity for nearby villages and 12,450 tonnes of ice per annum for local fisheries and food industries. However, at the expense of a 0.3 ¢/kWh increase in levelised energy costs, the ELFR can increase savings of biomass (100 t/a) and land (9 ha/a). Research limitations/implications: The research reviewed in this paper is primarily theoretical and further work will need to be undertaken to specify plant details such as piping layout, pump sizing and structure, and assess plant performance during real operational conditions. Originality/value: The paper considers the methodology adopted proved to be a powerful tool for integrating technology selection, optimisation, design and evaluation and promotes interdisciplinary methods for improving sustainable engineering design and energy management. © Emerald Group Publishing Limited.

An Interdisciplinary Approach to the Management of Vocal Cord Dysfunction in an Elite Female Swimmer: a Case Study

Acute pulmonary disorders are commonplace within the athletic population, with exercise induced bronchoconstriction (EIB), and vocal cord dysfunction (VCD) common diagnoses. VCD is a condition that causes the adduction of the vocal folds during inhalation, causing obstruction at the larynx and thereby a severely impaired sporting performance. VCD can be brought on by laryngeal irritants, emotional and psychological stress and asthma. The gold standard of treatment for VCD centres on an interdisciplinary approach from specialists that often include a respiratory consultant, speech and language therapist (SLT) and a psychologist. The present case study details the interdisciplinary approach to the treatment of an elite female swimmer with VCD with an intervention programme that lasted nine weeks, instigated by a local general practitioner (G.P.) who chose to engage a Sport Psychology Consultant (SPC) due to the sport-specific nature of the psychological stress experienced by the individual. The steps involved in the design of the sport psychology interventions are outlined and the relationship of those interventions to the work of the other specialists is discussed. The 9 week intervention programme was aimed at reducing perfectionist tendencies and competitive state anxiety using a combination of cognitive behavioural therapy (CBT), goal-setting and imagery. Overall, the treatment programme was deemed a success as perfectionism and competitive state anxiety levels reduced over time along with the frequency of VCD occurrence. This case study demonstrates the breadth of roles that can be undertaken by a SPC and raises awareness of a complex respiratory disorder that is not yet fully understood.

The use of mixed methods research in interdisciplinary educational journals

Mixed methods research is becoming increasingly important in several scientific areas. The analysis of prevalence rates is a new line of research that has emerged in mixed methods research, and this methodological approach has only been applied carefully in a handful of journals. The purpose of this article was to analyse the prevalence of mixed methods research in interdisciplinary educational journals. Moreover, the main characteristics of the mixed methods articles identified were examined. This study used a mixed methods approach to analyse these aspects. Specifically, a partially mixed sequential equal status multiple-case study design was applied with a development mixed methods purpose. Three educational journals in different disciplines were reviewed from 2005 to 2010 (Academy of Management Learning and Education, Educational Psychology Review, Journal of the Learning Sciences). The findings show differences among the journals in the prevalence rates and characteristics of the mixed methods studies

A multidisciplinary approach to the functional and esthetic rehabilitation of amelogenesis imperfecta and open bite deformity: a case report

The treatment of amelogenesis imperfecta (AI) with an anterior open bite (AOB) is a challenge for the clinician and often requires a multidisciplinary team of specialists. Most often, patients suffering from these conditions are young and a good functional and esthetic long-term result must be aspired. This clinical report illustrates the orthodontic, maxillofacial, restorative, and prosthodontic rehabilitation of a 20-year-old woman with a hypoplastic form of AI and an AOB malocclusion, having received treatment for the last 6 years. It included adhesive resin composite restorations, orthodontical and maxillofacial surgery with a one-piece Le Fort I osteotomy, and a genioplasty. Subsequent prosthodontic therapy consisted of 28 all-ceramic crowns whereby a solid interdigitation, a canine guidance, and consistent and regular contacts between tooth crowns could be achieved to assure a good functional and esthetic oral situation. The tooth preparation techniques guaranteed minimally invasive treatment. The patient was affected very positively. CLINICAL SIGNIFICANCE: This article describes an interdisciplinary approach to the successful treatment of a patient with a hypoplastic form of amelogenesis imperfecta over a period of 6 years. It starts with a discussion of the conservative steps taken during adolescence and concludes with the final prosthetic rehabilitation with all-ceramic crowns after reaching adulthood.

A Case Based approach to assess Waiting Time Prediction at an Intensive Care Unity

Waiting time at an intensive care unity stands for a key feature in the assessment of healthcare quality. Nevertheless, its estimation is a difficult task, not only due to the different factors with intricate relations among them, but also with respect to the available data, which may be incomplete, self-contradictory or even unknown. However, its prediction not only improves the patients’ satisfaction but also enhance the quality of the healthcare being provided. To fulfill this goal, this work aims at the development of a decision support system that allows one to predict how long a patient should remain at an emergency unit, having into consideration all the remarks that were just stated above. It is built on top of a Logic Programming approach to knowledge representation and reasoning, complemented with a Case Base approach to computing.

A Case-base Approach to Workforces’ Satisfaction Assessment

It is well known that human resources play a valuable role in a sustainable organizational development. Indeed, this work will focus on the development of a decision support system to assess workers’ satisfaction based on factors related to human resources management practices. The framework is built on top of a Logic Programming approach to Knowledge Representation and Reasoning, complemented with a Case Based approach to computing. The proposed solution is unique in itself, once it caters for the explicit treatment of incomplete, unknown, or even self-contradictory information, either in terms of a qualitative or quantitative setting. Furthermore, clustering methods based on similarity analysis among cases were used to distinguish and aggregate collections of historical data or knowledge in order to reduce the search space, therefore enhancing the cases retrieval and the overall computational process.

Age Prediction through Pelvis X-Ray Images - A Case Based approach to Problem Solving

It is well known that the dimensions of the pelvic bones depend on the gender and vary with the age of the individual. Indeed, and as a matter of fact, this work will focus on the development of an intelligent decision support system to predict individual’s age based on pelvis’ dimensions criteria. On the one hand, some basic image processing technics were applied in order to extract the relevant features from pelvic X-rays. On the other hand, the computational framework presented here was built on top of a Logic Programming approach to knowledge representation and reasoning, that caters for the handling of incomplete, unknown, or even self-contradictory information, complemented with a Case Base approach to computing.

An Artificial Intelligence Approach to Individuals' Age Assessment

A link between patterns of pelvic growth and human life history is supported by the finding that, cross-culturally, variation in maturation rates of female pelvis are correlated with variation in ages of menarche and first reproduction, i.e., it is well known that the human dimensions of the pelvic bones depend on the gender and vary with the age. Indeed, one feature in which humans appear to be unique is the prolonged growth of the pelvis after the age of sexual maturity. Both the total superoinferior length and mediolateral breadth of the pelvis continues to grow markedly after puberty, and do not reach adult proportions until the late teens years. This continuation of growth is accomplished by relatively late fusion of the separate centers of ossification that form the bones of the pelvis. Hence, in this work we will focus on the development of an intelligent decision support system to predict individual’s age based on a pelvis' dimensions criteria. Some basic image processing techniques were applied in order to extract the relevant features from pelvic X-rays, being the computational framework built on top of a Logic Programming approach to Knowledge Representation and Reasoning that caters for the handling of incomplete, unknown, or even self-contradictory information, complemented with a Case Base approach to computing.

An Integrated Soft Computing Approach to Hughes Syndrome Risk Assessment

The AntiPhospholipid Syndrome (APS) is an acquired autoimmune disorder induced by high levels of antiphospholipid antibodies that cause arterial and veins thrombosis, as well as pregnancy-related complications and morbidity, as clinical manifestations. This autoimmune hypercoagulable state, usually known as Hughes syndrome, has severe consequences for the patients, being one of the main causes of thrombotic disorders and death. Therefore, it is required to be preventive; being aware of how probable is to have that kind of syndrome. Despite the updated of antiphospholipid syndrome classification, the diagnosis remains difficult to establish. Additional research on clinically relevant antibodies and standardization of their quantification are required in order to improve the antiphospholipid syndrome risk assessment. Thus, this work will focus on the development of a diagnosis decision support system in terms of a formal agenda built on a Logic Programming approach to knowledge representation and reasoning, complemented with a computational framework based on Artificial Neural Networks. The proposed model allows for improving the diagnosis, classifying properly the patients that really presented this pathology (sensitivity higher than 85%), as well as classifying the absence of APS (specificity close to 95%).

El uso de la prensa diaria en la docencia de la biblioteconomía: una propuesta interdisciplinar

En la Diplomatura de Biblioteconomia i Documentació de la Facultat de Biblioteconomia i Documentació de la Universitat de Barcelona, desde las asignaturas impartidas en el primer semestre del tercer curso, Classificació i Indexació en Ciències Socials (optativa) y Recursos i Serveis en Unitats d¿Informació (obligatoria), realizamos durante los cursos 2003-2004/2005-2006 una actividad interdisciplinar a partir de la prensa. La elección de ambas asignaturas respondió, primero, al hecho de que el trabajo conjunto refuerza en el alumno una concepción global de la biblioteconomía. En segundo lugar, porque había una mayoría de alumnos matriculados en ambas asignaturas. Y, en tercer lugar, porque la Gestión forma parte de las Ciencias Sociales. Nuestra propuesta consiste en la presentación del uso selectivo de la prensa diaria como recurso pedagógico de los contenidos teóricoprácticos. Así, una entrevista a un director de orquesta nos permite comparar la dirección orquestal con el liderazgo de una organización. La lectura obliga a un ejercicio de comprensión, análisis y síntesis que concluirá con la aplicación de los lenguajes documentales. Con esta actividad (individual o grupal) conseguimos diversos objetivos propuestos por el EEES: dominio del vocabulario básico de ambas asignaturas, las técnicas propias de éstas y la capacidad de interpretar situaciones y adaptar procesos. En lo que respecta a competencias transversales, se perfecciona la comunicación oral y escrita, la capacidad de análisis y síntesis y, también, la capacidad de razonar críticamente. En relación con las habilidades, se mejoran las operaciones de la gestión de la información y las técnicas de administración de centros y servicios.

Els fonaments científics transdisciplinaris de la integració

La autora reflexiona sobre la necesidad de profundizar en los fundamentos científicos de los nuevos planteamientos integradores de la Educación especial desde el análisis de la relación entre el dentro y el fuera de las instituciones, la normalidad y, la anormalidad, el conocimiento científico y la experiencia vivida, la ciencia y la ética, como binomios significativos en la construcción de dicha disciplina y sus prácticas. Ahondar en los fundamentos científicos de la integración supone, para la autora, plantearse el sentido de una interdisciplinariedad que requiere de unos planteamientos crìticos con las escisiones y dicotomìas tradicionales del pensamiento científico positivista para alcanzar una transdisciplinariedad que aborde la complejidad y la unidad diversa de lo real.

Reflexiones sobre el espacio público = Thoughts on Public Space

En este artículo planteamos una aproximación a la idea de espacio público como articulador del conjunto de acontecimientos que intervienen en la vida de las ciudades. Entendemos este fenómeno como una red poliédrica y multidimensional, cuyo estudio pasa por el análisis de diversas problemáticas: la identificación de los límites entre espacio público y esfera pública; la conformación del espacio público construido; la aproximación teórica al fenómeno desde la contemporaneidad; la dimensión social del espacio público; y finalmente la perspectiva de la gestión de las ciudades. Todas estas dimensiones expresan una mirada crítica del objeto i ponen en valor niveles de trabajo interdisciplinar y multiescala, fundamentales para entender e intervenir en el espacio público de la ciudad contemporánea.

Der Baum in der Gegenwartskunst: Nachhaltigkeitsindikator

[deu]Dieser Artikel analysiert wie der Baum, hauptsächlich als lebendiges Wesen, im Bereich der zeitgenössischen Kunst verwendet wird. Der Baum wird als Objekt und als Subjekt behandelt, wird jedoch auch zum Experimentier- und Forschungsfeld der Kunst. Abgesehen von seinem Wesen als Objekt und Pflanze, erlangt er gleichzeitig als Standort eine räumliche Bedeutung. Anhand ausgewählter Beispiele wird aufgezeigt wie der Baum als weltweite Ikone sowohl auf die Zerstörung der Umwelt als auch auf die Ökologische Erhaltung und Zerstörung des Planeten in der zeitgenössischen Kunst hinweist.[eng]This paper analyses how the tree, mainly as a living being, is used in contemporary art. The tree is approached as object and subject, but also becomes a territory-space of experimentation and research. But beyond its plant and objectual character, the tree itself adopts a territorial sense as place. The diverse examples selected corroborate the use of the tree in contemporary art as a universal global icon of conservation and the environmental destruction of the planet.
