Reducing greenhouse energy consumption using novelty rooftop: a simulation

Recently, more than 80% of total energy of commercial greenhouse in the northern hemisphere is used just for heating. Mostly, the energy loss happens up to 40% caused by the poor U-value of the façades. Therefore, by lowering the U-value would decrease the energy consumption significantly. This simulation is conducted using EnergyPlus software to calculate the heat loss, heating demand and daylighting of a greenhouse with different envelope materials especially novelty rooftop. The orientation of buildings and its effect to electricity generated by semi-transparent PV double glazing are also discussed. In addition, the effect of the novel rooftop to daylighting inside the greenhouse is also investigated. The simulation shows that use materials with low U-value and novel rooftop could decrease the source energy consumption by 65% which is remarkable compared to commercial greenhouse. Besides, the best orientation for the PV module of the greenhouse in Nottingham, UK is facing west-south-east. While the indoor daylighting factor declined up to 65%. Therefore, using PVs with high efficiency would diminish the electricity losses and could be used for lighting energy alternative and others

99 p. Recurso Electr?nicoEn la formaci?n integral del ni?odesde los primeros a?os de la vida, es fundamental el desarrollo de la actividad creativa, la expresi?n gr?fico -pl?stica y la imaginaci?n, toda vez que constituye una actividad que promueve el desarrollo de la motricidad, el pensamiento cr?tico y la capacidad de proposici?n, como elementos fundamentales que le permiten al ni?o conocer, interactuar y transformar su entorno. Como parte del proceso de investigaci?n formativa que dispone el Programa de Licenciatura en Pedagog?a Infantil de la Universidad del Tolima, se llev? a cabo un proyecto enfocado hacia la implementaci?n de una propuesta pedag?gica que promueva el dise?o y la ejecuci?n de t?cnicas gr?fico? pl?sticascomo estrategia para el fortalecimiento de la motricidad fina en los ni?os y ni?as en nivel preescolar. El proyecto parte de la necesidad de permitir a los ni?os del nivel preescolar de la Instituci?n Educativa T?cnica La Sagrada Familia - Sede Versallesacceder a otros lenguajes a trav?s de actividades de su inter?s y agrado como espintar, modelar,rasgar, recortar, ensartar o dibujar, que se convierten en estrategias estimuladoras de su potencial creativo y creador, y a la vez fortalecen habilidades que son fundamentales para un adecuado desarrollo y desempe?o de su motricidad fina.Atrav?s del Proyecto Pedag?gico de Aula: Manitos creativas y juguetonas, se logra apropiar por los docentes, los padres de familia y los ni?os la expresi?n gr?fico ? pl?stica como una estrategia que fortalece la motricidad fina, a la vez que ofrece la instalaci?n de ambientes propicios para el aprendizaje desde el espacio preescolar. Palabras claves: Gr?fico - pl?stico, arte, motricidad fina, aprendizaje, expresi?n creativa.In the integral formation of the child from the first years of life, the development of the creative activity, the graphic expression - plastic and the imagination, since it constitutes an activity that promotes the development of the motor, critical thinking and the capacity for proposition, as fundamental elements that allow the child to know, interact and transform their environment. As part of the process of formative research provided by the Graduate Program in Pedagogy for Children at the University of Tolima, a project was carried out focusing on the implementation of a pedagogical proposal that promotes the design and execution of graphic techniques such as strategy for the strengthening of fine motor skills in preschool children. The project starts from the need to allow children of the pre-school level of the Educational Institution The Sagrada Familia - Versailles Headquarters to access other languages through activities of their interest and enjoyment such as painting, modeling, ripping, trimming, strumming or drawing , Which become strategies that stimulate their creative and creative potential, and at the same time strengthen skills that are fundamental for an adequate development and performance of their fine motor skills.Through the Pedagogical Project of Classroom: Creative and playful hands, it is possible to appropriate for teachers, parents and children the graphic - plastic expression as a strategy that strengthens fine motor skills, while offering the installation of environments Conducive to learning from preschool. Key Words:Graphic - plastic, art, fine motor skills, learning, creative expression

High-temperature magnetodielectric Bi(Fe0.5Mn0.5)O3 thin films with checkerboard-ordered oxygen vacancies and low magnetic damping

The possibility of affecting the magnetic properties of a material by dielectric means, and vice versa, remains an attractive perspective for modern electronics and spintronics. Here, we report on epitaxial Bi(Fe0.5Mn0.5)O3 thin films with exceptionally low Gilbert damping and magnetoelectric coupling above room temperature (<400 K). The ferromagnetic order, not observed in bulk, has been detected with a total magnetization of 0.44 μB/formula units with low Gilbert damping parameter (0.0034), both at room temperature. Additionally, a previously overlooked check-board ordering of oxygen vacancies is observed, providing insights on the magnetic and dielectric origin of the multifunctional properties of the films. Finally, intrinsic magnetodielectric behavior is observed as revealed by the variation of dielectric permittivity well above room temperature. These findings show the possibility of electric-field-controlled magnetic properties, in low Gilbert-damping-based spintronic devices, using single-phase multiferroic material

In Search of a Trade Mark: Search Practices and Bureaucratic Poetics

Trade marks have been understood as quintessential ‘bureaucratic properties’. This article suggests that the making of trade marks has been historically influenced by bureaucratic practices of search and classification, which in turn were affected by the possibilities and limits of spatial organisation and technological means of access and storage. It shows how the organisation of access and retrieval did not only condition the possibility of conceiving new trade marks, but also served to delineate their intangible proprietary boundaries. Thereby they framed the very meaning of a trade mark. By advancing a historical analysis that is sensitive to shifts, both in actual materiality and in the administrative routines of trade mark law, the article highlights the legal form of trade mark as inherently social and materially shaped. We propose a historical understanding of trade mark law that regards legal practice and bureaucratic routines as being co-constitutive of the very legal object itself

Bone marrow niche trafficking of miR-126 controls the self-renewal of leukemia stem cells in chronic myelogenous leukemia

Leukemia stem cells (LSCs) in individuals with chronic myelogenous leukemia (CML) (hereafter referred to as CML LSCs) are responsible for initiating and maintaining clonal hematopoiesis. These cells persist in the bone marrow (BM) despite effective inhibition of BCR–ABL kinase activity by tyrosine kinase inhibitors (TKIs). Here we show that although the microRNA (miRNA) miR-126 supported the quiescence, self-renewal and engraftment capacity of CML LSCs, miR-126 levels were lower in CML LSCs than in long-term hematopoietic stem cells (LT-HSCs) from healthy individuals. Downregulation of miR-126 levels in CML LSCs was due to phosphorylation of Sprouty-related EVH1-domain-containing 1 (SPRED1) by BCR–ABL, which led to inhibition of the RAN–exportin-5–RCC1 complex that mediates miRNA maturation. Endothelial cells (ECs) in the BM supply miR-126 to CML LSCs to support quiescence and leukemia growth, as shown using mouse models of CML in which Mir126a (encoding miR-126) was conditionally knocked out in ECs and/or LSCs. Inhibition of BCR–ABL by TKI treatment caused an undesired increase in endogenous miR-126 levels, which enhanced LSC quiescence and persistence. Mir126a knockout in LSCs and/or ECs, or treatment with a miR-126 inhibitor that targets miR-126 expression in both LSCs and ECs, enhanced the in vivo anti-leukemic effects of TKI treatment and strongly diminished LSC leukemia-initiating capacity, providing a new strategy for the elimination of LSCs in individuals with CML
