Potential applications of Salinity Gradient Power-Heat Engines for recovering low-temperature waste heat in cogeneration plants
2021
Abstract Salinity Gradient Power-Heat Engine is an innovative technology able to convert very low-temperature heat into electricity. Energy and economic benefits could be achieved by integrating this technology into cogeneration plants, where the exploitation of waste heat available during the operation could increase the revenues arising from “High-Efficiency” labels. For the first time, this paper proposes two potential applications in this field, and three illustrative case studies are purposely investigated. In the first case study, a salinity gradient-heat engine converts the waste heat available from a cogeneration plant serving an industrial process. In the second case study, a salin…
CHP retrofit for a large Med-Tvc Desalination Plant: High efficiency assessment for different design options under the current legislative EU framewo…
2015
Integrated power plants in "dual purpose" configuration may represent a viable option for energy cost abatement of desalted water produced by MED-TVC (Multiple Effect Distillation along with Thermal Vapour Compression). In this paper an existing large MED-TVC plant with a 36,000 m(3)/day capacity is studied: a plant retrofit is designed, based on a steam power plant with condensation and steam extraction used to drive the steam ejector. As the plant operates in CHP (Combined Heat and Power) mode, the possibility to assess the integrated "CHP + MED-TVC" as high efficiency cogeneration according to Directive 2004/8/EC is discussed. Based on a model developed in Engineering Equation Solver, a …
Environmental Stimulus Perception as an Incidence Factor in Social Interaction and Personality Development
2019
This paper seeks to analyze the impact of perceptual process, as a way of perceiving ourselves and others, as well as personality development and social attitudes which emerge from early interactions in the primary environment. Although many studies have highlighted the importance of early social interactions for both the genetic and psychobiological components of personality development, there is actually little data that examines the influence of these genetic factors on this process. This study focuses on the genetic bases of the perception process and its role in how we experience emotions and how we perceive the surrounding environment, starting with early interactions with caregivers.…
Estrategias emocionales en educación física a través del aprendizaje servicio: aplicación del programa siente jugando en alumnado de primaria
2019
Las emociones, la inteligencia emocional y la competencia socioemocional son algunos de los contenidos transversales que podemos desarrollar desde la Educación Física escolar. El juego motor es una fuente de estímulos y vivencias que favorece el desarrollo de las estructuras físicas y cerebrales que el alumnado de Primaria utilizará en su presente y futuro. El objeto de este estudio fue analizar las estrategias utilizadas para la resolución de conflictos tras la puesta en práctica de un programa de intervención denominado “Siente Jugando”, haciendo uso de la metodología Aprendizaje Servicio. La muestra estuvo formada por 93 participantes de Educación Primaria Obligatoria (EPO), de edades co…
Massive presence of insertion sequences in the genome of SOPE, the primary endosymbiont of the rice weevil Sitophilus oryzae
2008
Bacteria that establish an obligate intracellular relationship with eukaryotic hosts undergo an evolutionary genomic reductive process. Recent studies have shown an increase in the number of mobile elements in the first stage of the adaptive process towards intracellular life, although these elements are absent in ancient endosymbionts. Here, the genome of SOPE, the obligate mutualistic endosymbiont of rice weevils, was used as a model to analyze the initial events that occur after symbiotic integration. During the first phases of the SOPE genome project, four different types of insertion sequence (IS) elements, belonging to well-characterized IS families from γ-proteobacteria, were identif…

Children’s beliefs concerning school transition
2016
This study examines preschoolers’ beliefs concerning their transfer into primary education. Data from 1386 Finnish preschoolers were obtained using interviews with parents at the end of the children’s preschool year. The qualitative content analysis revealed categories, which encompassed peer relationships, relationship with teacher, learning, formal schoolwork, informal activities, comfortable school entry and no concerns. The results indicated that children’s beliefs concerning their prospective school entry centred on maintaining and making friendships, and that children possessed both negative and positive expectations about their relationship with their future teacher. Both girls and b…
Cultural Background and Second Language Acquisition
1988
Abstract Knubb‐Manninen, G. 1988. Cultural Background and Second Language Acquisition. Scandinavian Journal of Educational Research 32, 93‐100. The article examines – on the basis of a research study carried out in Swedish‐speaking schools in Finland – the significance that cultural conditions, such as gender and social background, have for second language learning. A model with gender and social background serving as the exogenous factors, school learning capacity and language use as the intervening variables, and proficiency in Finnish (second language) as a dependent variable was tested by means of the Lisrel method. The findings indicate that social background influences the learning of…
Curricular Reform, Constantly Changing Values and Consequences for Teacher Education
1996
Abstract In many European countries revised notions of learning and the dynamic nature of knowledge have brought about changes in teaching in primary education. The new views of learning, together with profound social changes, have similarly created pressures for curricular reform. This paper examines the repercussions of extensive curricular reform for teacher education, especially with respect to what can be done to develop teachers’ didactic skills and capabilities for curricular planning. The latter calls for profound skills and a sensitivity in following the changes taking place in society, and also the ability to discuss the values towards which the concrete goals of the teaching shou…
Grade repetition at primary school level "CP"
2005
This research on the grade retention to the CP erects a detailed inventory of the knowledge on this question which gives rise to the more of animated discussions between the researchers and the teachers, and this since a long time. By allying the historic, comparative, economical and educational approaches, she conveys principal empirical results attached to the many facets of this measure that is more than an educational done. The empirical contribution of this study is based on a longitudinal followed during two years about more than three thousand students on CP in public schools of the French department of the Côte d'Or. We highlight that the grade retention are received favourably by t…
