With the increasing interest in energy efficiency and resource protection, waste heat recovery processes have gained importance. Thereby, one possibility is the conversion of the heat energy into electrical energy by thermoelectric generators. Here, a the... see more

Thermal efficiency of borehole heat exchangers (BHE) is of crucial importance for the design and optimization of ground source heat pump (GSHP) system. This paper investigates thermal efficiency of a BHE with three drillhole diameters: 121 mm, 165 mm and ... see more

We investigated the synergetic effect between light-emitting diode (LED) lighting efficiency and building energy savings in heating and cooling using an alternative thermal operating system (ATOS) of indoor LED lighting integrated with the ventilation sys... see more

A large portion of the energy consumed worldwide is used for heating and cooling environments. In Brazil, the use of solar energy in homes experiences an increasing, despite the fact that not always an exclusively solar system can meet the entire energy d... see more

Enfoque sistémico de la superación profesional para el tratamiento del contenido de inmunología en la formación posgraduada del médico especialista clínico / Systematical focus of professional upgrade for the treatment of immunological content in the post Enfoque sistémico de la superación profesional para el tratamiento del contenido de inmunología en la formación posgraduada del médico especialista clínico / Systematical focus of professional upgrade for the treatment of immunological content in the postObjetivo: argumentar la necesidad del enfoque sistémico de la superación de los profesionales sobre la base de premisas que deben cumplimentarse en este proceso.Métodos: se emplearon métodos teóricos como el análisis históricológico, la modelación y los procedimientos de análisis y síntesis e inducción y deducción estructural. Se argumenta la necesidad del enfoque sistémico de la superación de éstos profesionales sobre la base de premisas que deben cumplimentarse en este proceso.Resultados: el enfoque sistémico como herramienta metodológica permite modelar el proceso de superación de los médicos especialistas clínicos en el área de la inmunología, como ciencia transdisciplinaria, desde una perspectiva integradora, interpretándose en su aspecto estático (estructura, componentes) y en su aspecto dinámico (funcionamiento y relaciones), sobre la base de un aprendizaje desarrollador. Al modelar este proceso también está en condiciones de ampliar las ofertas educativas; y por ende; la adquisición y transformación de conocimientos,habilidades y valores por parte de este profesional, así como la adecuada actualización sistemática de acuerdo con el desarrollo científico-técnico, al contribuir a elevar la productividad, eficiencia y calidad del trabajo, lo que implica un avance y desplazamiento de las fronteras del conocimiento.Conclusiones: el enfoque sistémico de la superación profesional del médico especialista clínico en el área de la Inmunología, constituye el punto de partida para el establecimiento de estrategias que posibiliten su perfeccionamiento con una concepción científica más acabada.ABSTRACTObjective: to argument the systematical focus of professional upgrade on the base of premises that should be complemented in this process.Methods: theoretical methods as historical logical analysis, modelation and the analysis processing analysis, synthesis induction and structural deduction. The necessity of systemical focus of these professional’s update is argued on the base of premises that should be complemented in this process.Results: the systematical focus as a methodological tool allow to modelate the upgrade process of clinicalspecialist physicians in the Immunology area, as a transdisciplinary science, from an integrated perspective interpretating in its static aspect (structure, components) and in its dynamic aspect (functioning and relationships) on the base of a developing learning. Modelating this process, is also in conditions to extend the educative offers and within the accession and transformation of knowledge, abilities and valors by part of this professional, as well as the satisfactory and systematic update according to the scientific technological development, contributing to upheave the productivity, efficiency and quality of the work, that implicate an advance and displacement of the knowledge’s frontiers.Conclusions: the systematical focus of professional upgrade of clinical specialist physician in the Immunology area constitutes a point of reference for the establishment of strategies that allow its improvement with a scientific conception more completed.Keywords: professional upgrade; profesional; systematical focus; clinical specialist physician; Immunology.

Methods: theoretical methods as historical logical analysis, modelation and the analysis processing analysis, synthesis induction and structural deduction. The necessity of systemical focus of these professional’s update is argued on the base of premises ... see more

Thermally Activated Building Systems (TABS) play an essential part in the thermal response of buildings, in terms of dynamic adaptation and energy storage, enabling the separation between thermal energy generation and use. TABS can operate with low temper... see more

It is well known that personal cooling improves thermal comfort and save energy. This study aims to: (1) compare different personal cooling systems and (2) understand what influences users’ willingness to adopt them. A series of experiments on several typ... see more

Evacuated tube solar water heater systems are widely used in China due to their high thermal efficiency, simple construction requirements, and low manufacturing costs. CPC evacuated tube solar water heaters with a geometrical concentration ratio C of less... see more

Under-floor air distribution (UFAD) systems are occupied-area-based air conditioning systems that generally offer advantages over ceiling-based air distribution (CBAD) systems in terms of energy efficiency and thermal comfort; accordingly, UFAD systems ha... see more
