    The fully de novo design of protein building blocks for self-assembling as functional nanoparticles is a challenging task in emerging nanomedicines, which urgently demand novel, versatile, and biologically safe vehicles for imaging, drug delivery, and gene therapy. While the use of viruses and virus-like particles is limited by severe constraints, the generation of protein-only nanocarriers is progressively reachable by the engineering of protein-protein interactions, resulting in self-assembling functional building blocks. In particular, end-terminal cationic peptides drive the organization of structurally diverse protein species as regular nanosized oligomers, offering promise in the rational engineering of protein self-assembling. However, the in vivo stability of these constructs, being a critical issue for their medical applicability, needs to be assessed. We have explored here if the cross-molecular contacts between protein monomers, generated by end-terminal cationic peptides and oligohistidine tags, are stable enough for the resulting nanoparticles to overcome biological barriers in assembled form. The analyses of renal clearance and biodistribution of several tagged modular proteins reveal long-term architectonic stability, allowing systemic circulation and tissue targeting in form of nanoparticulate material. This observation fully supports the value of the engineered of protein building blocks addressed to the biofabrication of smart, robust, and multifunctional nanoparticles with medical applicability that mimic structure and functional capabilities of viral capsids.

    2012-06-01

    Full Text Available The need to produce more sustainable buildings has been influencing the design decisions all over the world. That’s why it is imperative, in Brazil, the development of strategies and method to aid the decision making during the design process, focused on high quality environmental. This paper presents a decision support tool based on the principles of sustainable construction developed by the Project, Architecture and Sustainability Research Group (GPAS of Federal University of Rio de Janeiro – Brazil. The methodology has been developed for the selection of a preliminary design of a laboratory to be built at Rio Technology Park at the University campus. The support provided by GPAS occurred in three stages: the elaboration of the Reference Guide for the competitors, the development of a methodology to evaluate the proposed solutions (based on environmental performance criteria and the assistance of the members of jury in the trial phase. The theoretical framework was based upon the concepts of the bioclimatic architecture, the procedures specified by the certification HQE® (Haute Qualité Environnementale and the method suggested by the ADDENDA® architecture office. The success of this experience points out the possibility to future application in similar cases.

    Tools and criteria for Cost-Benefit Analysis (ACB) of energy saving in bioclimatic designs (DB) are presented, for which a reference project is established. Based on the traditional design of air conditioning of a building and with the support of this one, the estimation of costs and benefits of the same building is made; but with passive systems. The tools used consider related resources such as time and money. Criteria are used such as: Present value (VP), Equivalent Annual Cost (EAC) and the Cost of the conserved Energy (CEC). The costs related to the construction, maintenance and operation of the design are taken into consideration. The differences between the design of reference and the Bioclimatic Design, established from the application of these criteria, allow evaluating the economic margin as far as operation and maintenance. Finally, the cost of the conserved energy of the bioclimatic measures is evaluated as an initiative for energy saving and calculates the present value from them in all of the period of useful life of the bioclimatic design.

  6. Digital models for architectonical representation

    Directory of Open Access Journals (Sweden)

    Stefano Brusaporci

    2011-12-01

    Full Text Available Digital instruments and technologies enrich architectonical representation and communication opportunities. Computer graphics is organized according the two phases of visualization and construction, that is modeling and rendering, structuring dichotomy of software technologies. Visualization modalities give different kinds of representations of the same 3D model and instruments produce a separation between drawing and image’s creation. Reverse modeling can be related to a synthesis process, ‘direct modeling’ follows an analytic procedure. The difference between interactive and not interactive applications is connected to the possibilities offered by informatics instruments, and relates to modeling and rendering. At the same time the word ‘model’ describes different phenomenon (i.e. files: mathematical model of the building and of the scene; raster representation and post-processing model. All these correlated different models constitute the architectonical interpretative model, that is a simulation of reality made by the model for improving the knowledge.

    Barth, Johannes V.

    2007-05-01

    The engineering of highly organized systems from instructed molecular building blocks opens up new vistas for the control of matter and the exploration of nanodevice concepts. Recent investigations demonstrate that well-defined surfaces provide versatile platforms for steering and monitoring the assembly of molecular nanoarchitectures in exquisite detail. This review delineates the principles of noncovalent synthesis on metal substrates under ultrahigh vacuum conditions and briefly assesses the pertaining terminology—self-assembly, self-organization, and self-organized growth. It presents exemplary scanning-tunneling-microscopy observations, providing atomistic insight into the self-assembly of organic clusters, chains, and superlattices, and the metal-directed assembly of low-dimensional coordination architectures. This review also describes hierarchic-assembly protocols leading to intricate multilevel order. Molecular architectonic on metal surfaces represents a versatile rationale to realize structurally complex nanosystems with specific shape, composition, and functional properties, which bear promise for technological applications.

    The energy world crisis of 1973 besides the problems of supplying and the raise of prices also propitiated in various countries, a reaction aimed at the efficient use and conservation of energy and to the application of a common sense architecture: the BIOCLIMATIC ARCHITECTURE, which is based in utilization in the buildings of the alternate energies, such as the wind power, etc. The obtaining natural environmental comfort conditions and the saving and efficient use of energy in the buildings are the fundamental objectives of the BIOCLIMATIC ARCHITECTURE. Under these considerations several passive systems for the thermal control in buildings have been set forth, which have been applied in different climatic regions of the planet. This paper presents and analyzes the potential saving of energy through the implementation of practices such as the installation of artificial high efficiency lighting systems and passive cooling systems for the thermal control of an educational building -the central library of the Universidad Autonoma Metropolitana, Azcapotzalco Unit, located in Mexico City. The objective of this study is aimed at the reduction of the consumption of energy in the library and the attainment of comfortable hygrothermal environment for its occupants. Studies performed during the first stage of the research, have permitted the identification of a excessive energy consumption and lack of comfort hygrothermal conditions and the need of high quality air inside the library. These actions have been focussed to two aspects. The first one is related to the improvement in the operation of the electric installation and in the library lighting. These actions were based in the substitution of lamps, load balancing of the secondary circuits, checking and improvement of the electric insulation a better selectivity of lighting switches installation in the vicinity of windows and areas with greater natural illumination.

    Hossam, M. K. Aboulfotouh

    The paper is an attempt to show the architectonic method of the ancient Egyptian designers for encoding the horizontal-projections of the moon's declinations during two events of the minor lunar standstills, in the design of the site-plan of the horizon of the Giza pyramids, using the methods of descriptive geometry. It shows that the distance of the eastern side of the second Giza pyramid from the north-south axis of the great pyramid encodes a projection of a lunar declination, when earth's obliquity-angle was ~24.10°. Besides, it shows that the angle of inclination of the causeway of the second Giza pyramid, of ~13.54° south of the cardinal east, encodes the projection of another lunar declination when earth's obliquity-angle reaches ~22.986°. In addition, it shows the encoded coordinate system in the site-plan of the horizon of the Giza pyramids.

  4. Intrinsic connections and architectonics of posterior parietal cortex in the rhesus monkey

    International Nuclear Information System (INIS)

    By means of autoradiographic and ablation-degeneration techniques, the intrinsic cortical connections of the posterior parietal cortex in the rhesus monkey were traced and correlated with a reappraisal of cerebral architectonics. Two major rostral-to-caudal connectional sequences exist. One begins in the dorsal postcentral gyrus (area 2) and proceeds, through architectonic divisions of the superior parietal lobule (areas PE and PEc), to a cortical region on the medial surface of the parietal lobe (area PGm). This area has architectonic features similar to those of the caudal inferior parietal lobule (area PG). The second sequence begins in the ventral post/central gyrus (area 2) and passes through the rostral inferior parietal lobule (areas PG and PFG) to reach the caudal inferior parietal lobule (area PG). Both the superior parietal lobule and the rostral inferior parietal lobule also send projections to various other zones located in the parietal opercular region, the intraparietal sulcus, and the caudalmost portion of the cingulate sulcus. Areas PGm and PG, on the other hand, project to each other, to the cingulate region, to the caudalmost portion of the superior temporal gyrus, and to the upper bank of the superior temporal sulcus. Finally, a reciprocal sequence of connections, directed from caudal to rostral, links together many of the above-mentioned parietal zones. With regard to the laminar pattern of termination, the rostral-to-caudal connections are primarily distributed in the form of cortical ''columns'' while the caudal-to-rostral connections are found mainly over the first cortical cell layer

  5. Changes in the architectonics of the root apical meristem at radiation mutagenesis

    International Nuclear Information System (INIS)

    Acute irradiation of pea germs induced an increase of the cell population polymorphism, vacuolation, and parenhimatization of individual cells and cell packets in the root meristem. The degree of topology disturbances is usually correlated with the dose of irradiation. Increasing the dose reduces the meristem size and increases the inactivation frequency of cells and the cell packet deformation. The structural architectonics of the meristem is deformed at the 33%-frequency of aberrant anaphases (FAA), but, nevertheless, it remains. At 50% FAA, the topology of cellular rows and the zoning of apex are destroyed, and sizes of the meristem are decreased to 'the critical' level.

    2014-12-01

    This work presents mineralogical and chemical characteristics of weathering crusts developed on sandstones exposed to various air pollution conditions. The samples have been collected from sandstone tors in the Carpathian Foothill and from buildings in Kraków. It has been stated that these crusts differ in both fabric and composition. The sandstone black crust from tors is rich in organic matter and composed of amorphous silica. Sulphate incrustations accompanied by dust particles have been only sometimes observed. Beneath the black crust, a zone coloured by iron (oxyhydr)oxides occurs. The enrichment of the surface crust in silica and iron compounds protects the rock interior from atmospheric impact. The sandstones from architectonic details are also covered by a thin carbon-rich black crust, but they are visibly loosened. Numerous salts, mainly gypsum and halite, crystallise here, thus enhancing deterioration of the rock. Moreover, spherical particles originated from industrial emissions are much more common. Gypsum in natural outcrops, forms isolated and well-developed crystals, whilst these found on the architectonic details are finer and densely cover the surface. Such diversity reflects various concentrations of acid air pollutants in solutions. PMID:25037099

    The domestic sector consumes almost one quarter of the national electrical energy. In order to reduce in an important manner the power consumption in dwellings there is an integral alternative based on three elements: the bio-climatic design, the saving and efficient use of the energy in equipment and apparatuses, and the use of centralized air conditioning systems. Besides saving the electrical and thermal power consumption, with this scheme, comfort conditions are pretended to be reached in dwellings and, contributing at the same time, to the diminution of polluting emissions. [Spanish] El sector domestico consume casi una cuarta parte de la energia electrica nacional. Con objeto de reducir de manera importante el consumo de energia en las viviendas, se presenta una alternativa integral, basada en tres elementos: el diseno bioclimatico, el ahorro y uso eficiente de la energia en equipos y aparatos, y la utilizacion de sistemas de climatizacion centralizados. Ademas del ahorro en el consumo de energia electrica y termica, con este esquema se pretende alcanzar condiciones de confort en las viviendas y, al mismo tiempo, contribuir a la disminucion de emisiones contaminantes.

    Since one of the restrictive problems when investing in energy saving is the uncertainty of obtaining the planed savings, a technique in the risk handling for energy efficiency projects, called Insurance for the Energy Saving (IES) is presented. IES economically stimulates those who implement projects for energy saving so they go beyond the normal measures and really obtain significant saving levels, thus contributing to the fulfillment of national objectives in energy saving. In order to reduce the risk of low performance in energy caused by saving projects there exist the international performance measurement and the protocol of investment (IMPVP) as well as diagnoses and starting processes, whereas in order to transfer the financial risk that a saving project represents, mechanisms such as FDIC insurance, conversion of the debt in values, Saving's Guarantees, Performance Bonuses or Guarantee Bonuses and Insurances for Energy Saving can be of great help. This article deals on the IES insurance policies, their loss control management, successful cases, benefits, particular advantages, place in the market and refers argued insurance exceptions and perception surveys. [Spanish] Dado que uno de los problemas restrictivos a la hora de invertir en el ahorro de energia es la incertidumbre de obtener los ahorros proyectados, se presenta una tecnica en el manejo del riesgo para proyectos de eficiencia energetica llamada Seguro para el Ahorro de Energia (SAE). SAE estimula financieramente a quienes implementan proyectos para el ahorro de energia con el fin de que vayan mas alla de las medidas normales y consigan niveles significativos de ahorro, contribuyendo asi al cumplimiento de objetivos nacionales de ahorro energetico. Para reducir el riesgo de bajo desempeno de energia provocados por proyectos de ahorro existe la medicion del desempeno internacional y el protocolo de inversion (IMPVP) asi como diagnosticos y procesos de arranque, mientras que para transferir el

    In the framework of the ERASMUS Intensive Programme (IP) on "Global Heritage and Sustainability: Geological, Cultural and Historical", a round table was organised on "Geoeducation and Geoethics in Earth and Planetary Sciences" taking advantage of the role of the IP coordinator also being responsible for the "Heritage Stone Task Group" (HSTG) at IUGS and in addition the presence of the responsible for the "IUGS Commission on Geoscience Education, Training and Technology Transfer" (IUGS-COGE) and President of the International Association of Geoethics (IAGETH). Another responsible for the round table was an expert on natural risks. This topic formed an important part of the program of this IP, that in 2013 was celebrating its third and final edition. This round table was one of the first exchanges of views among different IUGS commissions and task groups. It offered a very good opportunity to analyse how aware is the scientific community about the importance of education and ethics in communicating natural hazards risks and their relationship preserving architectonic heritage, which was the main subject of the Intensive Programme. Eighteen participants contributed to the event with the following backgrounds: Geology, Engineering Geology, Architecture, Civil Engineering, Environmental Engineering, Civil Protection and English Philology. All participants were either undergraduate students or graduate students, at a Masters and Doctoral level from the following countries: Spain, Portugal, Italy and Hungary. The purpose of this study is to establish an initial link between geoethics and geoeducation when teaching university students at different levels of subject such as natural hazards risks communication and the preservation of architectonic heritage. The respective IUGS Commissions and Task Groups can lead the debate. This work was sponsored by the ERASMUS Intensive Programme 2012-1-ES1-ERA10-54375 and it was done within the framework of the IUGS Heritage Stone Task

    The traditional sugar mill is inefficient from the energy point of view. Most of the sugar mills were designed to use all the available bagasse, due to the risk of spontaneous ignition and environmental pollution. Consequently, the steam generators, the turbines and other components were designed to work with low efficiencies. Each ton of sugar produced generates a power potential equivalent to four to six oil barrels (bagasse and residues). That is to say, a sugar mill is capable of producing 500 ton/day of sugar, equivalent to an oil well of 2000 to 3000 barrels/day and one thermoelectric power plant of 15,000 kW. Under this context an analysis is made of the sugar mills in Latin America and the Caribbean as one of the ways of increasing their efficiency and obtain great energy savings. As far as steam generation the appropriate use of energy is dictated by the boilers' efficiency. [Spanish] El ingenio azucarero tradicional es ineficiente desde el punto de vista energetico. La mayoria de los ingenios azucareros se disenaron para usar todo el bagazo disponible, debido al riesgo de ignicion espontanea y contaminacion. En consecuencia, los generadores de vapor, las turbinas y demas componentes fueron disenados para trabajar con bajas eficiencias. Cada tonelada de azucar producida genera una potencialidad energetica equivalente de cuatro a seis barriles de petroleo (bagazo y residuos). Es decir, un ingenio capaz de producir 500 ton/dia de azucar equivalente a un pozo de petroleo de 2000 a 3000 barriles/dia y una termoelectrica de 15000 kW. Bajo este contexto se hace un analisis del ingenio azucarero en Latinoamerica y el Caribe como una de las vias para incrementar su eficiencia y lograr grandes ahorros en la energia. En cuanto a generacion de vapor se refiere, el buen uso de la energia viene expresado por la eficiencia de las calderas.

  15. Consciousness as a phenomenon in the operational architectonics of brain organization: Criticality and self-organization considerations

    International Nuclear Information System (INIS)

    In this paper we aim to show that phenomenal consciousness is realized by a particular level of brain operational organization and that understanding human consciousness requires a description of the laws of the immediately underlying neural collective phenomena, the nested hierarchy of electromagnetic fields of brain activity – operational architectonics. We argue that the subjective mental reality and the objective neurobiological reality, although seemingly worlds apart, are intimately connected along a unified metastable continuum and are both guided by the universal laws of the physical world such as criticality, self-organization and emergence

    The design and construction of current buildings has been characterized, most of all, in the last 30 years, for the lack of consideration in the design process of aspects that nowadays represent a fundamental importance. These aspects are related to energy conservation and environmental protection, with man as the main center of attention for the optimum satisfaction of its physiological as well as psychological needs. In this paper are presented the causes for the lack of consideration of the mentioned aspects and guidelines to follow are set forth for their integration in the design process. Also the architecture potential with a bioclimatic approach is analyzed, for energy saving in buildings.

    For Plant CIVAC of Nissan Mexicana, the energy saving began in the year of 1990. From then, different programs have been developed using different strategies for energy saving until arriving at the Benchmarking with other Plants of Japan, which represents a new challenge, since it opened up an area of opportunity of saving in processes that generally were known in detail as far as to its main function (to make vehicles with quality, cost and opportunity of delivery), but the parameter of energy consumption of by unit and its benefits in relation to the cost was unknown. This was endorsed by the high Direction and began with the optimization of training for the operation of each equipment with the involvement of the user (Production), the engineering area (that establishes the process) and the maintenance area. We designed a general program where the basic activities were included, such as the general and special activities. Each one of them fulfilled its objective, but the special activities took us to the optimization of the processes, finding excess of energy in the design conditions.

    Full Text Available A partir del análisis de las cuentas nacionales de México por sector institucional se descubre una relación de sustitución perfecta entre el ahorro externo y el ahorro interno. Cambios en la disponibilidad de ahorro externo generan, mediante diferentes mecanismos, variaciones en el mismo sentido en la participación de los salarios y los dividendos en el producto y en sus propensiones al consumo; y en sentido opuesto en el ahorro interno de las empresas. La relación de causalidad es clara; a mayor disponibilidad de ahorro externo mayor ingreso de los hogares y mayor consumo, no al revés. Mediante una reformulación del modelo de N. Kaldor, (1955, para incluir el ahorro externo y diferenciando las ganancias entre dividendos y ganancias retenidas, se formalizan y estiman, econométricamente, las relaciones entre los coeficientes de inversión, ahorro externo y dividendos por un lado y la distribución del ingreso entre salarios y ganancias por otro. Se resalta la importancia estratégica que la conducta económica de los dirigentes empresariales, manifiesta en las decisiones de inversión y en la propensión a distribuir las ganancias , ejerce sobre el crecimiento económico la distribución del ingreso, el consumo, el ahorro y la balanza de pagos. Hasta hoy, México se ha endeudado con el exterior para aumentar su consumo no para ampliar su planta productiva.

    High energy consumption is one of the serious problems in the world today. Newly, this question has taken on not only economic, but also social and ecological importance. In order to reduce the amount of fossil energy, energy diagnosis are one of the most useful tools for increasing the energy efficiency in buildings. In the Faculty of Engineering, dependency of the Universidad Autonoma de Yucatan, Mexico a program of energy diagnosis was developed under an ongoing project entitled energy savings program, which begun in 1996. This paper describes a methodology about diagnosis building energy consumption building shell and energy efficiency in a case study. No doubt future developments are likely to lead to changes in the estimates. We hope that, nevertheless, this study will contribute to increased energy efficiency in this Faculty.

    The present work looks for integrating the actions of energy saving that can be applied in educative institutions, not concerning the level or size of the same ones. The actions go from questions of making aware the student population until those involved in the change in the operation, migration and implementation of technology. Without overlooking the formative aspect that the educative institutions have and the social commitment of these last ones. It is important that the saving measures have as mission to achieve a culture focussed to make efficient use of the resources, of energy as well as material. This culture must be born from the classrooms and must transform the way to be and act of the student community that will permeate itself with the society. Let us remember that actions are worth more than words, so the educative institutions must preach with the example. [Spanish] El presente trabajo busca integrar las acciones de ahorro de energia que pueden ser aplicadas en instituciones educativas, no importando el nivel o tamano de las mismas. Las acciones van desde cuestiones de concienciar a la poblacion estudiantil hasta las que involucran el cambio en la operacion, migracion e implementacion de tecnologia. Sin perder de vista el aspecto formativo que tienen las instituciones educativas y el compromiso social de estas ultimas. Es importante que las medidas de ahorro tengan como mision lograr una cultura enfocada a hacer uso eficiente de los recursos, tanto energeticos como materiales. Dicha cultura debe nacer desde las aulas y debe transformar la manera de ser y actuar, de la comunidad estudiantil que se permeara con la sociedad. Recordemos que las acciones valen mas que las palabras, asi que las instituciones educativas deben predicar con el ejemplo.

    Full Text Available In order to address architectural heritage conservation, we must be familiar with the medium with which we will be working, its function and response to incidents or external actions (natural or anthropogenic and how the buildings were conceived and constructed in order to understand how they will be affected by the intervention process to which they will be subjected and adopt the adequate measures so these processes will not harm the buildings. An important element is the foundation. This is a fundamental, yet often forgotten, element. It is important to know the history of the foundations, how and why they were constructed and for this, it is essential to study architectural treatises as the origin of their design. It is surprising to read classical architecture treatises and observe that they do not refer to calculations of dimensions, but to constructive solutions that today may seem clever because they are obvious, but in reality, they do not address the thoughts of the designer or builder. The historic architectural treatises on construction that significantly influenced Spanish construction, which we studied and will present in this article, include Vitruvius and Palladio as well as the developments in the eighteenth and nineteenth centuries, and even into the first half of the twentieth century: (Vitruvius (1st century BC, Palladio (1524, Alberti (1582, Cristóbal de Rojas (1598, Fray Laurencio San Nicolás (1639, Brizguz y Bru (1738, Rieger (1763, Fornes y Gurrea (1841, Espinosa (1859, Marcos y Bausá (1879, Ger y Lobez (1898 and Barberot (1927.

    Full Text Available Propõe-se, neste artigo, uma reconstrução da interpretação de Kant para a teoria da gravitação universal de Newton, em particular dos seus aspectos metafísicos e metodológicos, a partir da análise do §38 dos Prolegômenos a toda metafísica futura. A pretensão é mostrar que a interpretação da teoria newtoniana nessa passagem apóia-se integralmente no programa de uma "metafísica da natureza", que Kant elaborou nos Princípios metafísicos da ciência da natureza como condição necessária a uma autêntica ciência da natureza. Com respeito a esse programa, o desafio será mostrar que a sua sustentabilidade requer um tipo de unidade particular que permita reunir os princípios transcendentais heterogêneos da natureza formaliter e materialiter spectata; isto é, exige-se um modelo de unidade arquitetônica, cuja possibilidade real é exibida na complexa e bem-sucedida articulação de princípios de origens diversas que Newton operou em sua teoria da gravitação universal.In this article, we propose a reconstruction of Kant's interpretation of Newton's theory of universal gravitation, in particular, its metaphysical and methodological aspects, beginning by the analysis of §38 from the Prolegomena to any future metaphysics. The intention is to show that the interpretation of Newtonian theory in this passage rests completely on the program of a "metaphysics of nature" that Kant propose in Metaphysical principles of the science of nature as a necessary condition of an authentic science of nature. As to this program, the challenge will be to show that its sustainability requires a kind of particular unity that allows to put together the heterogeneous transcendental principles of formaliter and materialiter spectata nature, that is, it is required a model of architectonic unity, whose real possibility is exhibited in the complex and well succeeded articulation of principles from various sources that Newton worked in this theory of

    The objective of this project is to reduce the operation costs by means of the energy saving through the use of the compressed air system. For this purpose the solenoid valves controlled per time and the manually acted valves of sphere must be replaced by pneumatic purges that remove from the system the condensed humidity without discharging air and which act automatically when the water reaches the level of unloading in its deposit. The pressure level is the reduction of the operation rank of pressure in the compressors, satisfying the operation requirements of the process equipment. [Spanish] El objetivo de este proyecto es reducir el costo de operacion mediante el ahorro de energia en la utilizacion del sistema de aire comprimido. Para ello se tienen que remplazar las valvulas solenoides controladas por tiempo y valvulas de esfera actuadas manualmente por purgas neumaticas que remueven del sistema la humedad condensada sin descargar aire y que actuan en forma automatica al alcanzar el agua el nivel de descarga en su deposito. El nivel de presion es la reduccion del rango de operacion de presion de los compresores, satisfaciendo los requerimientos de operacion de los equipos de proceso.

    The enormous electric energy consumption in buildings represents an important area of saving opportunities. The design of installations without advanced technical illumination criteria, the absence of standardization over energy efficiency, the lack of observation of the existing standards and guides, the continuous load growth in existing installations and the lack of appropriate maintenance, are some of the causes of the inefficient use of electric energy in buildings. Although the problems, and consequently the solutions, are exclusive for each unit, some of the former are frequently repeated. In this paper the problems found along more than 40 audits conducted in large buildings of different types in Mexico city are commented. [Espanol] El enorme consumo de energia electrica en edificios representa una importante area de oportunidad para ahorro. El diseno de instalaciones sin criterios luminotecnicos avanzados, la ausencia de normalizacion sobre eficiencia energetica, la falta de observancia de las normas y recomendaciones vigentes, el continuo crecimiento de carga en instalaciones existentes y la falta de mantenimiento adecuado son algunas de las causas del uso ineficiente de la energia electrica en inmuebles. Aunque los problemas y por tanto las soluciones son particulares para cada unidad, algunos de los primeros se repiten frecuentemente. En este trabajo se comentan los problemas encontrados a lo largo de mas de 40 auditorias realizadas a inmuebles grandes de diversos tipos en la ciudad de Mexico.

    Full Text Available Tile imprecise use of terms such as money, savings, credit, and investment allow for various mix-ups. Several  of them can be cleared up if we take into account that the most important part of the means of payment is that I'lhich serves a different purpose, for which there exists a demand, and I'lhich entails a cost that the community pays in different ways. Money, defined as such, is subject to the laws of supply and demand, and to the control of its volume especially because it is a good which is found in limited quantities. Therefore, money demand is the inverse of the income velocity of money.El uso impreciso de términos tales como dinero, ahorro, crédito e inversión da lugar a diversas confusiones, varias de ellas se despejan si se toma en cuenta que la porción más importante de los medias de pago es aquella que presta un servicio diferente, para el cual existe una demanda y que entraña un costo que la comunidad paga de diversas maneras. El dinero, así definido, está sujeto a  las leyes de la oferta y la demanda y al control de su volumen, en especial porque es un bien que se encuentra en cantidad limitada. Se aclara entonces que la demanda no es más que el inverso de la velocidad ingreso del dinero.

    Full Text Available Landscape design research is important for cultivating spatial intelligence in landscape architecture. This study explores GIS (geographic information systems as a tool for landscape design research - investigating landscape designs to understand them as architectonic compositions (architectonic plan analysis. The concept ‘composition’ refers to a conceivable arrangement, an architectural expression of a mental construct that is legible and open to interpretation. Landscape architectonic compositions and their representations embody a great wealth of design knowledge as objects of our material culture and reflect the possible treatment of the ground, space, image and program as a characteristic coherence. By exploring landscape architectonic compositions with GIS, design researchers can acquire design knowledge that can be used in the creation and refinement of a design. The research aims to identify and illustrate the potential role of GIS as a tool in landscape design research, so as to provide insight into the possibilities and limitations of using GIS in this capacity. The critical, information-oriented case of Stourhead landscape garden (Wiltshire, UK, an example of a designed landscape that covers the scope and remit of landscape architecture design, forms the heart of the study. The exploration of Stourhead by means of GIS can be understood as a plausibility probe. Here the case study is considered a form of ‘quasi-experiment’, testing the hypothesis and generating a learning process that constitutes a prerequisite for advanced understanding, while using an adjusted version of the framework for landscape design analysis by Steenbergen and Reh (2003. This is a theoretically informed analytical method based on the formal interpretation of the landscape architectonic composition addressing four landscape architectonic categories: the basic, the spatial, the symbolic and the programmatic form.

    This paper presents some of the fundamental issues related to energy conservation programs in general and to the petroleum industry in particular with the purpose of integrating them both, that is, considering not only the energy issues, but also the ecological and economical aspects. This is achieved by using the two fundamental laws of thermodynamics (the science that studies energy, its characteristics, and its transformations) through the use of the exergy concept, which is a measure of the energy quality and of its withdrawal with respect to the environment. The origins of the present-day technologies, regarding energy conservation, the short, medium and long term general strategies and the implementation stages of the integral programs of energy conservation are presented, and it concludes with a series of general policies aimed at making the energy conservation programs more congruent with the maintenance of a sustainable development. [Espanol] En este trabajo se presentan algunos aspectos fundamentales relacionados con los programas de ahorro de energia en general, y en la industria petrolera en particular, con objeto de lograr que los mismos sean integrales, es decir que consideren no solo los aspectos puramente energeticos, sino tambien los aspectos ecologicos y economicos. Esto se logra utilizando conjuntamente las dos leyes fundamentales de la termodinamica (la ciencia que estudia la energia, sus caracteristicas y sus transformaciones), mediante la utilizacion del concepto de exergia, que es una medida de la calidad de la energia y de su alejamiento con respecto al medio ambiente. Se presentan los origenes de las tendencias tecnologicas actuales en materia de ahorro de energia, las estrategias generales a corto, mediano y largo plazos y las etapas en la implementacion de programas integrales de ahorro de energia, para concluir con una serie de politicas generales tendientes a lograr que los programas de ahorro de energia sean congruentes con el

    In the present paper the evaluation of the potential of saving of electrical energy in Mexico is presented, by means of the substitution of old refrigerators of low efficiency by modern high efficiency ones. This potential is very ample, since the replacement of the old models by new follows a very slow curve, if the economic difficulties of the Mexican families are considered and that, on the other hand, the technology of the domestic refrigerators is so reliable that they have a very long life and they are not easily rejected. In field work have been found refrigerators operating with ages of more than 30 years and still 40. In Mexico, it is estimated that the refrigeration is responsible for around 29% of the of electricity consumption in homes settled in tempered climate and of 14 % in those of warm climate in which air conditioning is used. The proposal of this work is the organization of a governmental program of accelerated substitution of refrigerators that helps to acquire an efficient refrigerator and to reject the old ones. The results indicate that if a total renovation of the park of domestic refrigerators is made, the saving of electrical energy would reach the 5.2 TWh/a which represents the 44.5% of the total consumption of 11.7 TWh in a year. [Spanish] En el presente trabajo se presenta la evaluacion del potencial de ahorro de energia electrica en Mexico, mediante la substitucion de refrigeradores antiguos de baja eficiencia por modernos de alta eficiencia. Este potencial es muy amplio, ya que el reemplazo de los modelos viejos por nuevos sigue una curva muy lenta, si se consideran las dificultades economicas de las familias mexicanas y que, por otro lado, la tecnologia de los refrigeradores domesticos es tan confiable que tienen una vida muy larga y no se desechan facilmente. En trabajos de campo se han encontrado refrigeradores operando con edades de mas de 30 anos y aun 40. En Mexico, se estima que la refrigeracion es responsable de alrededor del

Nevertheless, an important point is to know, in the most concrete and specific form, the nature and other possible utilization options of the different urban transportation systems, as well as its energy impact and the possibility of a well oriented energy conservation. The purpose of this paper is to present in a concrete manner the different types of vehicles used in the urban public transportation, making an energy comparison, besides setting forth a program of actions tending to the energy saving for the vehicles that nowadays operate in the main cities of our country. The main actions are pointed out and the basic characteristics for their initiation, which can be summarized in three large groups: -action in the proper enterprises and with existing vehicular park. -actions over the management and exploitation of the transportation systems. -action for the utilization of new equipment and more efficient vehicles. A detailed explanation of each one of these actions and their impact on the energy consumption are the final purpose of this study.

    In Mexico does not exist guides of bio-climatic design whose reading and interpretation be so simple that any architect or professional of the construction without experience in the bio-climatic area, can use when designing or remaking suitable a construction. A group formed by ten professors (project coauthors) of the Faculty of Architecture of the Universidad Michoacana have undertaken the task of making tables, with profuse graphical material, for each one of the main sub climates of our country, with respect to their economic and urban importance. The selection of the sub climates was done taking into account that they are those that are present in the capital cities and other cities of high urban importance. Basically each one of the tables contains: description of the sub climate and its location by climatic region, relevant physical-geographic aspects, excellent climatic conditions, strategically bio-climatic to use, proposed strategies of design from the solar and Aeolian axes (direction and location of spaces and openings, materials and constructive systems, solar and Aeolian control system). The present work is part of a book on bio-climatic design for architecture in Mexico of proximate publication, that will contain, divided according to the 10 proposed climatic regions by the Instituto de Geografia of the UNAM, folders with the sub climates that are presented in each one of the 10 climatic regions, and in each of them, tables with the different selected cities.

    Every one involved with the conservation and efficient use of electric energy, has listened in reiterative occasions to the causes that changed the conventional mentality at the beginning of the seventies. Nevertheless, there are many persons that still ignore that by using the energy rationally, their costs are significantly reduced, their comfort is enhanced and the environmental problems are minimized. Specifically, in the domestic sector, from the figures reported by the Comision Federal de Electricidad (CFE) in 1996, the electric energy sold was 28,410 Gwh, that is, 23.4% of the total consumption (121,579 Gwh). Table 1 presents the average by tariff in the national domestic sector, which shows that 20% of the electricity consumed was required for environmental conditioning (air conditioning, evaporative coolers and electric fans). The above figures quantitatively show that there is a strong impact in the consumption of electric energy due to weather conditions. For this reason, currently the Comision Nacional de Ahorro de Energia (CONAE) and the Fideicomiso para el Ahorro de Energia (FIDE) are promoting standards and projects to propitiate the rationalization in the use of energy, besides of achieving the improvement of thermal comfort conditions. One more case would be the Fideicomiso para el Aislamiento Termico de la Vivienda en Mexicali (FIPATERM), which promotes the financing of saving measures and efficient energy use in cities with extreme climate. This paper describes the strategy that was followed by the Instituto de Investigaciones Electricas (IIE), for the development of the human and material infrastructure, that has allowed the sustainment of several projects in the saving and efficient use of energy in CFE, CONAE, FIDE, FIPATERM and the Lawrence Berkeley National Laboratory (LBNL), concretely in relationship with the thermal analysis of dwellings.

    The projects for the energy saving in hotels represent a great opportunity to reduce the operation costs in the demand and consumption of electrical energy, since the existing facilities can take advantage of new technologies in illumination, air conditioning, refrigeration and heating. By their constitution, the hotels work the year around uninterruptedly and must provide all type of services to the guests and working personnel, which originates that they consume great amounts of energy in air conditioning, lightning, laundry, etc., since the prestige of the installation depends on it. [Spanish] Los proyectos para el ahorro de energia en hoteles representan una gran oportunidad para reducir costos de operacion en la demanda y consumo de energia electrica, ya que las instalaciones existentes pueden aprovechar nuevas tecnologias en iluminacion, aire acondicionado, refrigeracion y calefaccion. Por su constitucion, los hoteles trabajan ininterrumpidamente todo el ano y deben proporcionar toda clase de servicios a los huespedes y personal que labora, lo cual origina que consuman grandes cantidades de energia en aire acondicionado, iluminacion, lavanderia, etc., pues de ello depende el prestigio de la instalacion.

    termico generado al interior de las edificaciones por las inadecuadas propiedades de los materiales de construccion, se desarrollaron en este trabajo filtros solares con base en hierro por medio de los cuales se logra un control selectivo de la radiacion solar que se transmite a traves de las ventanas. Estos filtros solares consisten en peliculas delgadas de FeO depositadas sobre sustratos de vidrio cal-sosa (el mas usado en nuestro pais para las edificaciones) de 600x300x3 mm, por medio de la tecnica de sputtering asistida con radiofrecuencia y magnetrones planos, partiendo de un blanco de hierro puro de 127x254 mm y usando un plasma de argon. Para obtener el grado de oxidacion deseado en el hierro, pequenas muestras (45 x 22 mm) fueron sometidas a un proceso de calentamiento en una atmosfera reductora constituida de 50% H{sub 2} + 50% N{sub 2}, durante un periodo de tiempo de 10 minutos a una temperatura de 400 C. Los filtros solares con base en FeO presentan una transmisividad de 30.2% para el intervalo visible del espectro electromagnetico (radiacion con longitud de onda de 380-780 nm), y de 39.9% para el infrarrojo cercano (radiacion con longitud de onda de 780-2500 nm); mientras que su reflectividad es de 17.5 y 19%, para los intervalos visibles e infrarrojo cercano del espectro electromagnetico respectivamente. Se realizo una simulacion, a traves del software Energy 10, del comportamiento energetico de una casa-habitacion cuando utilizan en las ventanas vidrios simples (una lamina) tipo cal-sosa, asi como tambien cuando esta misma edificacion usa en las ventanas los filtros solares con base en FeO desarrollados. Ambos casos se comparan obteniendose asi los posibles ahorros de energia por el uso de dichos filtros solares en las ventanas. Las simulaciones fueron llevadas a cabo para diferentes localidades del pais, obteniendose que los filtros solares con base en FeO desarrollados, permiten ahorros de energia principalmente por concepto de acondicionamiento de aire

    1996-12-31

    The motor-compressors are a key part of the industrial processes. The reliability and efficient operation of a compressor is critical. The surge phenomenon is a threat in the reliability of a compressor and therefore for the process. Surge, in a centrifugal compressor is defined as a dramatic flow and pressure drop, including back-flow. This is always a significant process disturbance. Continuous surge results into costly process shutdowns and mechanical damages. To prevent surge, and control the discharge pressure with simple or obsolete controls it is needed to vent air to the surrounding atmosphere. This form of control is very inefficient and costly. An advanced control with leading technology, besides providing an economical value preventing surge damages, offers substantial energy saving reducing or eliminating the venting of air to the atmosphere. [Espanol] Los motocompresores son un aparte clave de los procesos industriales. La confiable y eficiente operacion de un compresor es critica. El fenomeno de surge es una amenaza a la confiabilidad de un compresor y por lo tanto del proceso. El surge en un compresor centrifugo es definido como una dramatica caida de flujo y presion, incluyendo flujo inverso. Esto es siempre un significante disturbio del proceso. El surge continuo resulta en costosos paros de proceso y danos mecanicos. Para prevenir el surge y controlar la presion de descarga con controles simples u obsoletos, es necesario ventear aire a la atmosfera. Esta forma de control es muy ineficiente y costosa. Un control avanzado con tecnologia de punta ademas de proveer valor economico previniendo danos por surge, provee sustanciales ahorros de energia reduciendo o eliminando el venteo de aire a la atmosfera.

    Full Text Available El entorno competitivo de las entidades de depósito ha sufrido fuertes cambios durante las dos últimas décadas, y en la actualidad se caracteriza por una fuerte rivalidad entre las empresas del sector. En este contexto, las entidades bancarias deben dotarse de sistemas de información ágiles y flexibles que les permitan dar respuesta a las nuevas necesidades gerenciales y a las actuales exigencias de la dirección estratégica. Desde esta perspectiva, en el presente trabajo se estudian las características de los distintos sistemas de transferencia interna de fondos aplicables en las entidades bancarias, procediendo a un análisis comparativo de los mismos, y, posteriormente, se presentan los principales rasgos que caracterizan a los sistemas de transferencia de fondos correspondientes a las cajas de ahorros y a las cajas rurales, a partir de los resultados obtenidos de una encuesta realizada en dichas entidades. The competitive environment of monetary financial institutions has undergone great changes over the last two decades, and at present is characterized by strong competition among the companies of the sector. In this context, the monetory financial institutions should be endowed with agile and flexible information systems that allow them to respond to the new managerial necessities and the current demands of Strategic Management. Thus, in this paper, first we analyse the characteristics of the different funds-tranfer- pricing methods applicable in the banks and go on to carry out a comparative analysis of the former. Secondly, we present the main features that characterize the funds-transfer-pricing methods in Spanish Savings Banks and Spanish Rural Banks, based on the results obtained from a survey carried out among these companies.

    connected to some Cultural Heritage element; this allowed to compare differences in recent substituted capitals, important reconstruction events, signs of the evolution of the building. All data were then treated and analysed to deepen the knowledge about the most meaningful aspects of different construction techniques and use of materials, provenance of raw materials, stone alterations and static-structure decay. As the result, a base was created to read common behaviours, design choices, recursive constructive solutions, and the "models" guiding the ancient intentions. A great effort has been made to keep together all these different kind of data, from the chemical and petrophysical information on the geomaterials to the geometrical description of the building, creating a robust relationship between the architectural and geological approach to the subject. The very specific photogrammetric survey of the stones sampled will be presented in details with a clear description of the applied processing and of the reached results. This contribution will present the progress state of this research, together with some widening about the most important churches between the investigated group, like: St. Saturnino in Cagliari (South Sardinia), St. Trinità of Saccargia (near Sassari, North), St. Antioco of Bisarcio in Ozieri (North-central), St. Giusta (near Oristano, central-Western).

    Full Text Available Las reformas legislativas que han afectado en los últimos tiempos a la organización y el funcionamiento del sistema financiero español han tenido una especial repercusión en el ámbito de las cajas de ahorros. La tramitación parlamentaria de la Ley 44/2002, de 22 de noviembre, de Medidas de Reforma del Sistema Fianciero, reavivó el debate sobre su régimen jurídico y la necesidad de acotar la intervención pública en su seno. Ahonda en ello la Ley 26/2003 , de 17 de julio, de Transparencia, que extiende al ámbito de las cajas la preocupación por el corporate governance. Ambas normas responden a la necesidad de dar respuesta a algunos de los problemas más inmediatos a que se enfrentan estas entidades, si bien adolecen de un defecto fundamental por cuanto no abordan de forma exhaustiva la regulación de la institución. Se perpetúa así la trayectoria tradicional de "parcheo" del régimen jurídico aplicable a las mismas, evitando entrar en la cuestión esencial de la definición de su naturaleza jurídica y abocando a las cajas, en consecuencia, al díficil reto de acompasar su vocación social tradicional a las nuevas exigencias legales en pro de una mayor eficiencia, racionalidad y neutralidad de su acitividad económica.Recent legal changes pertaining to the organization and performance of the Spanish financial system have had significant repercussions on the savings banks sector. The law on financial market reform passed in 2002, Ley Financiera, raised once again the debate on their legal situation and the urge to cut down public influence on their management. The 2003 Transparency Law, Ley de Transparencia, follows this reform and extends corporate governance to Spanish savings banks. Both Laws seek to confront some of the most important issues raised by these credit institutions, but they also share the flaw of not regulating its legal framework and status completely. They continue, therefore, to add "patches" to the savings

    The catalysis, defined by the alchemists since its appearance, as that something or Philosophical Stone, with a special power to transform matter by means of the energy, has always represented a challenge to mankind, even more now, when most of the goods needed for its survival are related to a chemical process and nowadays, when they can not be imagined without the presence of a catalyzer. In the reciprocity between the chemical change and the catalyzer, the energy utilized represents the critical point. Once stated the above, it becomes interesting the study of the impact and the consequence of the binomial catalysis-energy in relation to the fuel recovery processes and the emission control processes, originated by its combustion, where the main objective is in establishing an analysis criterion for energy conservation with different trends; the first one, on the impact of the application of optimum catalytic systems in the fuel recovery processes and the second one on the optimum catalytic processes for emissions control. [Espanol] La catalisis desde su aparicion definida por los alquimistas como ese algo o piedra filosofal, con una fuerza especial para la transformacion de la materia mediante la energia, siempre ha representado un reto para el hombre, mas aun en la actualidad donde la mayoria de los bienes necesarios para su supervivencia estan relacionados con un proceso quimico y que hoy en dia no se conciben estos sin la presencia de un catalizador. En la reciprocidad entre el cambio quimico y el catalizador, la energia utilizada representa el punto critico. Dado lo anterior, resulta interesante el estudio del impacto y trascendencia del binomio catalisis-energia en relacion con los procesos para la obtencion de los combustibles y de los procesos para el control de emisiones, producto de la combustion de los mismos, donde el objetivo primordial esta en establecer un criterio de analisis de ahorro de energia con diferentes directrices; la primera, el impacto

    In a lighting system the discharge lamps (fluorescent and high intensity discharge (HID)), ballast and controls are generating elements of harmonics. As a consequence of the tendency of saving energy, the use of electronic ballasts and controls that integrate dimmers, daylight and present sensors has increased in order to optimize the energy use. This paper presents the harmonics generation resulting from the fluorescent lamps operating different electronic ballasts as well as their electronic controls. Likewise, are also shown the effects caused by generation of harmonics components by the lighting system in the electric system that go from the voltage and current distortion, the presence of currents in the neutral conductor in balanced systems to the repercussions in the metering equipment such as watthour meters and the effects the lighting equipment suffer due to the presence of harmonics, such as the power factor decrease in ballasts that are of high power factor and the temperature increment in the magnetic type ballasts. [Espanol] Dentro de un sistema de iluminacion, las lamparas de descarga (fluorescentes y alta intensidad de descarga {sup H}ID{sup )}, balastros y los controles son elementos generadores de armonicas. A consecuencia de la tendencia al ahorro de energia se ha incrementado el uso de balastros electronicos y controles que integran atenuadores de luz (dimmers), sensores de luz natural y de presencia con el fin de optimizar el uso de la energia. Este trabajo presenta los resultados de generacion de armonicas para lamparas fluorescentes, operando diferentes balastros electronicos asi como con controles electronicos. Asi mismo son presentados los efectos causados por la generacion de componentes armonicas por el sistema de iluminacion dentro del sistema electrico que van desde la distorsion en voltaje y corriente, la presencia de corrientes dentro del conductor neutro en sistemas balanceados, asi como la repercusion en los equipos de medicion tales

    This paper presents a diagnosis of the electrical energy consumption in the library of the Azcapotzalco Unit of the Universidad Autonoma Metropolitana, to determine the actions that can be implemented for energy conservation. This without disturbing the lighting and thermal comfort. The analysis showed that, by changing the reflecting surfaces of the lighting lamps, the number of units can be reduced, without lowering the illumination level below the recommended values. The saving was estimated for replacement of the fluorescent lamps for others of metallic halogenides in the areas where the ceiling is high; for the installation of switches to improve the selectivity in turning on and turning off the lamps, achieving this way a better usage of the natural light; for the reduction of the electric load of the air conditioning units which will be obtained in incorporating induced draft shafts; and for an improvement in the electric and ballast installation. For the actions that turned out to be redeemable in three years the assistance of the Fideicomiso de Apoyo al Programa de Ahorro de Energia del Sector Electrico (FIDE) of the Comision Federal de Electricidad (CFE) has been available. It is expected that the execution of the modifications will be carried out in the November and December months of 1993, and the results will be evaluated in 1994.

    The bioclimatic design profits of the natural resources for the improvement of the construction quality as well as the user's life. The combination of these two concepts within the architectonic design generates an interesting duality to consider within the understanding of the user's physical and psychological environment and the obtaining of a correlation of reality and dreams. Environmental psychology is focused on the researching of the psychological effects of the architectonic environment on the human experience and behavior. Human behavior works under parameters established during its development. Through the habits and styles of life practiced in childhood those parameters establish themselves to later on obtain satisfiers in the search of the life quality of human beings. [Spanish] El diseno bioclimatico aprovecha los recursos naturales para el mejoramiento de la calidad de la construccion y vida del usuario. La combinacion de estos dos conceptos dentro del diseno arquitectonico, genera dualidad interesante de entender el medio ambiente fisico y psicologico de los usuarios y obtener una identificacion entre la realidad y los suenos. La psicologia ambiental se ha enfocado a investigar sobre la relacion de los efectos psicologicos del ambiente construido o arquitectonico sobre la conducta y la experiencia humana. La conducta humana trabaja bajo parametros establecidos durante el desarrollo del mismo, a traves de los habitos y estilos de vida desde su infancia van marcando esos parametros que despues sirven para lograr satisfactores en la busqueda de la calidad de vida de los seres humanos.

    A methodology is proposed that should be followed in any thermal electric power plant to determine the load value at which a unit requires a second circulation water pump without affecting the thermal regime and avoiding an excessive auxiliaries consumption in partial loads. In applying this method the power plant would have an energy saving equivalent to the auxiliaries consumption during an hour, when the unit as operating at full load. [Espanol] Se propone una metodologia que debe seguirse en cualquier central termoelectrica para determinar el valor de la carga en la cual una unidad requiere de la segunda bomba de agua de circulacion sin afectar el regimen termico y evitadose un excesivo consumo de auxiliares en cargas parciales.

    Full Text Available El aprovechamiento del agua lluvia es una práctica interesante, tanto ambiental como económicamente, si se tiene en cuenta la gran demanda del recurso sobre las cuencas hidrográficas, el alto grado de contaminación de las fuentes superficiales y los elevados costos por el consumo de agua potable en una institución educativa. Este proyecto presenta la ingeniería conceptual de una propuesta de diseño de un si stema de aprovechamiento de agua lluvia como alternativa para el ahorro de agua potable en usos tales como la descarga de sanitarios, el lavado de zonas comunes, entre otros. Se presenta, adicionalmente, un análisis aproximado de la viabilidad técnica y económica de dicho aprovechamiento en una institución educativa del municipio de Caldas, Antioquia. Se desarrollan en este documento tres aspectos principales: el cálculo de los volúmenes disponibles de agua lluvia en la zona, la evaluación del volumen de agua potable ahorrado con el aprovechamiento del agua lluvia, la estimación del presupuesto para la construcción del sistema y la proyección del ahorro generado al utilizarlo. Los resultados sugieren que el aprovechamiento de agua lluvia es una opción técnicamente viable, pero financieramente no, pues la inversión inicial es alta, por lo que es importante buscar financiación externa para desarrollar este tipo de proyectos que representan una solución interesante para contribuir al desarrollo sostenible de la institución educativa.

    An extension study of the Financing Program for Energy Saving looked for the evaluation of the electric energy saving potential obtained by the replacement of air conditioning equipment and the application of thermal insulation in 30 houses of two Mexican cities with warmth climate. In a joint effort with Comision Federal de Electricidad the consumption files of the users were analyzed and field measurements of electric demand and of refrigeration were made. As a following step the change of the refrigeration necessities derived from the application of thermal insulation were evaluated as well as the energy efficiency improvement obtained by the substitution of the air conditioning equipment and the favorable results obtained by the implementation of both measures - thermal insulation and change of air conditioning equipment in a joint form. This way, as a conclusion, the optimum sequence of application of these measures is revealed.

    Full Text Available El presente artículo se propone indagar sobre las especificidades que adopta el uso del dinero en sectores subalternos a partir de un trabajo de campo realizado en un asentamiento de la localidad de José León Suárez, provincia de Buenos Aires. Se sostiene que en el cruce entre, por un lado, las modalidades que asume la percepción del ingreso en dicha población y, por el otro, los mecanismos formales e informales que regulan la relación con el dinero, se generan prácticas específicas de consumo, crédito y ahorro que tienden a profundizar las desigualdades existentes en dichos sectores. En este sentido, el trabajo plantea que las prácticas de consumo son estructuradas en torno a las condiciones de percepción del ingreso, es decir, a partir del trabajo del que se disponga – formal o informal –, la regularidad del pago – fijo o no y, en el primer caso, con que frecuencia temporal se percibe – y la forma del mismo – si se halla bancarizado o no –. Vinculado a esto, se desprenden distintas posibilidades de acceso a créditos – en bancos, en casas de venta de bienes para el hogar, de “confianza” entre parientes y vecinos y/o en comercios del lugar– que suponen otras tantas formas de relación con el tiempo y de la vivencia y calculabilidad del mismo. Estas cuestiones, entrecruzadas por reglamentaciones, exclusiones y controles que operan modelando las formas que adopta el gasto, encuadran formas diferenciales del manejo del dinero y del ahorro.

    éthode wolffienne qu’il n’est supposé communément, et leur débat gagne en profondeur.This paper presents Christian Wolff’s argument on the evidence of metaphysical principles as expounded in his article Directive notions and the true use of the first science (1729. This article was a central and yet forgotten reference for those who responded to the 1762/1763 academy questions such as Kant. Wolff here asserts that metaphysics has a kind of certainty that is equal or even superior to mathematics and that it communicates such certainty to the remaining sciences. It is this Wolffian thesis that Kant attacked in 1763. A closer reading allows to acknowledge more philosophical premises of Wolff’s argument. Wolff’s thesis on the mathematical certainty of metaphysics inverts the former order of priorities between metaphysics (ontology and mathematics. According to Wolff (who here seemed to be influenced by Euclides’ geometry, metaphysical notions are at the foundation of mathematical and logical rules. Notions such as “identity”, “thing”, “possibility” etc. have a “directive” or methodical status : they direct the mind searching the truth. Together, these notions constitute a modern and “architectonic” ontology. This framework shows the methodological continuity between Wolff and Kant. Even though Kant contested the form of Wolff’s system, his response still formed part of the general program sketched by Wolff. Kant still attempted to found some kind of architectonic metaphysics containing a table of directive concepts. From this viewpoint, Kant owes more to Wolff than what has been commonly assumed, and the deep and complex debate between the two thinkers calls for more attention.

    The project of installation of speed variator in fossil power stations (CT's) of Comision Federal de Electricidad (CFE), as an energy saving measure, is a pilot project that began with the support of the Subdivision de Generacion, and promoted by the Energy Saving Program of the Electric Sector (PAESE), with the putting in operation of an equipment in the condensate pump of the Punta Prieta II C. T. U3. The energy saving observed was substantial, fluctuating between the 19.4% at high loads (at 90% load) and the 71.1% at low loads (at 40% load) of the generating unit. With these results, it was decided to extend the scope of the project with the installation of 6 more equipment for equal number of fossil power stations, located in 4 of the 5 Regions of Generation. The fossil power stations, selected for this stage of the project were: C. T. Felipe Carrillo Puerto U1, C.T. Lerma U4, C.T. Salamanca U1, C.T. Monterrey U6, C.T. Francisco Villa U3 and the C.T. Punta Prieta II-U1. The equipment was in operation during the first quarter of 1998, and the first results indicate an energy savings average per equipment, between 39% and 52%. The recovery of the investment fluctuates between the 48.4% and the 87.6% in less than two years of operation, with which a maximum period of recovery of 3 years is expected. The estimated potential of energy saving, considering the application of these devices in condensate pumps, feedwater pumps (where no speed variator is installed) forced draft fans, induced draft fans and gas recirculation fans, as well as circulation water pumps, of the existing Generating Power stations, ascends to an annual total of 830,000, which represents an approximate 9.4% of the National consumption of self services.

    Full Text Available Las cajas de ahorros Españolas son posiblemente el caso más significativo a nivel mundial de entidades multistakeholders, no sólo por su misión, sino también en su gobernanza. La teoría multifiduciaria de los stakeholders plantea, al menos de forma teórica lo que en las cajas de ahorros ha sido una realidad por más de un siglo. Así, las cajas se convierten en un “caso de laboratorio” para analizar la viabilidad e idoneidad de una gobernanza participada por el conjunto de stakeholders de la organización. Nuestra hipótesis es que la gobernanza multistakeholder, así como la orientación hacia los stakeholders, generan un planteamiento estratégico diferente, no centrado en los beneficios. Por tanto, la gobernanza multifiduciaria puede perfectamente ser más ineficiente en relación con indicadores económico-financieros referidos a los shareholders de una entidad. Sin embargo, estas entidades deberían ser más eficientes si se tienen en cuenta indicadores relacionados con la generación de valor social. Con el fin de contrastar la eficiencia relativa hemos utilizando la población de bancos y cajas de España y los datos de 2009, utilizando la técnica de Análisis Envolvente de Datos con objeto de comparar la eficiencia económica, social y global de ambos tipos de entidades. Los resultados indican una diferenciación significativa entre estos dos grupos de entidades financieras en relación con la eficiencia social y económica, si bien no ocurre lo mismo cuando se utiliza la eficiencia global –económica más social-. Por lo que podemos concluir que la eficiencia en la gestión entre inputs y outputs en cajas de ahorros y bancos es similar. / Probably, Spanish savings banks are the most significant worldwide multistakeholders entities, not only because of their mission, but also in their governance.

    In this paper the importance that the preventive maintenance has as an important ingredient of the internal policies of the companies for the promotion of the energy saving is discussed. It considers that the department of planning and production control must take into account very seriously the importance of programmed preventive maintenance in order to maintain the continuity of the production process and with this eliminate the bottle necks that adversely affect it and consequently the the company's image before the clients, besides contributing positively the promotion of energy saving. The faults that stop the production process inflict losses of income and adversely affect the yield of the company, in addition, they increase the production cost or the plant expenses associated to the repair of the damaged equipment, in the worst of the cases, important penalties will have to be paid for the delayed delivery of the product to the client. By keeping the correct operation of the equipment, increasing its availability and assuring that all the safeties of these operate correctly we will be contributing to the optimal operation of the enterprise system and avoiding the additional consumption of energy associated to the failure of an equipment and interruption of the production line. The preventive maintenance also promotes, the order and the cleanliness, the safety and hygiene in the work centers and the protection to the environment. Once the prevention has won the battle to the correction, one enters the field of diagnosis, handling the service periods in an optimal way in benefit of the production line. In this stage it can be spoken of entering the application of Total Productive Maintenance.

    This paper shows the results attained in energy saving through a project of potable water pumping, which took an investment of $433,043.00 and an internal rate of return of 126%. This project puts into evidence that it is possible to reduce between 15 and 30% of the total invoicing for energy consumption in potable water pumping if an equipment of poor efficiency is replaced by another of high efficiency. The project was requested by the Guanajuato's State Water Comision and the Municipal Bureau of Sewage and Potable Water, with the double intention of reducing the energy consumption along with the corresponding invoicing and incrementing the output of the wells in order to improve the potable water supply. In the site two high efficiency submersible motor-pumps were installed previously to the energy diagnosis that triggered profitable operation results and a convenient invoicing.

    In Mexico, the culture of energy saving began more than one decade ago, but the benefits are not yet concrete. The Mexican society, requires new designs of dwellings adapted to its needs and in addition modifies the present systems of construction that do not include criteria of design for the thermal comfort, the energy saving and the sustainability. It is urgent to reconsider the urbanism of the cities, as well as the promotion of the concept of sustainable development in all the branches of human activity. The design of dwellings must significantly integrate the energy and environmental components to reduce to the power consumption and the CO{sub 2} emissions. [Spanish] En Mexico, la cultura de ahorro de energia se inicio hace mas de una decada, pero los beneficios aun no son palpables. La sociedad mexicana, requiere de nuevos disenos de viviendas que se adapten a sus necesidades y que ademas modifiquen los sistemas de construccion actuales que no incluyen criterios de diseno para el confort termico, el ahorro de energia y la sustentabilidad. Es urgente reconsiderar el urbanismo de las ciudades, asi como la promocion del concepto de desarrollo sustentable en todas las ramas de la actividad humana. El diseno de la vivienda debe integrar los componentes energeticos y medioambientales, para reducir significativamente el consumo de energia y las emisiones de CO{sub 2}.

    Full Text Available A partir de una aproximación teórica y empírica a las empresas sociales y su rol en el desarrollo local, se buscó establecer cómo las cooperativas de ahorro y crédito constituyen una estrategia pertinente para el avance social y económico de las comunidades mexicanas. Para tal efecto se recurrió al método cualitativo recurriendo a la estrategia de estudio de caso, seleccionando cuatro organizaciones ubicadas en zonas clasificadas como de alta marginación de acuerdo con indicadores oficiales en México. Los casos corresponden a cooperativas fundadas con la participación de miembros de la iglesia católica y cuya actividad financiera ha sido fundamental en el ámbito local en el que funcionan. Los resultados muestran que la organización de cooperativas, la acción voluntaria de sus miembros y en algunos casos el apoyo del Estado, constituyen instrumentos eficaces en la promoción del desarrollo local. Los principales beneficios en favor de los asociados se traducen en el otorgamiento de créditos y de servicios adicionales como becas educacionales y servicios de salud. Pudo constatarse, que con la práctica de los principios y valores del cooperativismo se facilita el trabajo en equipo y los asociados desarrollan habilidades emprendedoras y directivas que los benefician individual y colectivamente mejorando su calidad de vida. / From an empiric and theoretical approach to the social enterprises and its role at the local development, it was sought to establish how the credit and saving cooperatives are a pertinent strategy for the economic and social advance from the Mexican communities.

    The technological advances generate far reaching changes in all types of installation. The new spaces and the existing ones justify the introduction of new technologies taking into account important economic considerations, mostly when the advantage of daylight is taken into consideration in industrial and commercial lighting. In the daylight design it is necessary to know the solar transit, the atmospheric conditions, the architectural design of the building, the materials and the control elements, etc. to apply with precision the calculation method. The fundamental lighting technic have varied little. In the greatest part of commerces and industries the general lighting is used, that produces an illumination more or less uniform on the working areas, which guarantees a total freedom for the placement of machinery, working benches, racks, exhibitors, clothes racks, etc.. This type of lighting is obtained by means of the use of a more or less regular series of skylights. The adequate localized lighting is used in those zones where because of the presence of obstructions or unfavorable slant of the working plan are not sufficiently well lighted by the general lighting system. The daylight use in accordance with the every moment availability will permit in many working centers a sensible diminution of the artificial lighting time, provided that the characteristics of the control operation of the installation permit it, along with modern controlling devices and the great variety of efficient saving lamps.

[Spanish] Se presentan los resultados de un esfuerzo por contribuir al desarrollo de nuevos elementos constructivos acordes a las necesidades bioclimaticas de las edificaciones en Mexico que propicien el ahorro de energia. Se desarrollaron ventanas con dos tipos de recubrimientos, uno exclusivamente de oxido cuproso (Cu{sub 2}O), y otro resultado del deposito sucesivo de una pelicula de sulfuro cuprico (CuS) sobre otra de oxido cuproso. El segundo tipo de ventanas presento un adecuado control al paso de la radiacion infrarroja, lo que permite reducir aun mas la cantidad de radiacion calorifica que pasa a traves de la ventana. Durante las condiciones de calentamiento, estas ventanas dejan pasar en el peor de los casos, la mitad del calor, reduciendo la carga termica al interior de la habitacion o del edificio. Durante condiciones de enfriamiento, la ventana permite la salida del calor a la mitad de la velocidad, manteniendo durante mas tiempo la temperatura de confort del interior. Los recubrimientos de los mencionados compuestos de cobre fueron fabricados en los laboratorios de los Institutos de Ingenieria y Fisica de la Universidad Nacional Autonoma de Mexico (UNAM). Se utilizo la tecnica de erosion ionica o sputtering de un blanco de cobre 99.999% con ayuda de un plasma compuesto de argon (70%) y oxigeno (30%), que posibilita la oxidacion del cobre y el deposito del Cu{sub 2}O. Se utilizo un sustrato de vidrio flotado comercial de 600x400 mm., este tamano del vidrio estuvo determinado por las limitaciones de espacio de nuestra camara de deposito. La ventana asi obtenida presenta una agradable coloracion amarillenta y gran luminosidad, sin embargo, en el infrarrojo cercano, unicamente bloquea el 50%. Para las propiedades deseadas de control termico era necesario reducir aun mas el paso del calor. Para ello se incorporo una pelicula de sulfuro cuprico con la cual fue posible alcanzar

    The Norm NOM-008-ENER-2001 no longer commands the efficient handling of energy from functional equipment or apparatuses but from a well planned architectural design that allows diminishing the energy use for cooling purposes, consequently this Norm refers to the conduction and radiation principles regulating the heat gain through the cover portions of a building. The Norm defines a reference theoretical building that will dictate the propitious heat gain for the projected buildings. Here the functioning logic of the Norm in respect to both principles is mathematically explained as well as an application example is developed considering the calculations made for the Norm's reference building and for the projected one, the final revision of the fulfillment of the norm, proposals of solutions and the conclusions. [Spanish] La Norma NOM-008-ENER-2001 comanda el manejo eficiente de energia electrica ya no a partir de equipos o aparatos funcionales sino a partir de un bien planeado diseno arquitectonico que permita disminuir el uso de energia para fines de enfriamiento.

    Altos Hornos de Mexico (AHMSA) is an iron and steel industry integrated to Grupo Acereros del Norte in Monclova, in the Coahuila state. With an a installed capacity of 3.1 millions of tons per annum o liquid steel. In its installations, AHMSA has the highest capacity blast furnace installed in Mexico, blast furnace No. 5, that has a useful volume of 2,163 cubic meters, designed to produce 4,800 tons of pig iron per day. The basic goal to achieve in the operations involved in the production of steel through the pig iron production in the blast furnace, is the hot metal production at the lowest attainable cost within the quality requirements specified by the steel makers. The most important criterion for the recognition of the attained success is the fuel consumption per ton of pig iron produced, with coke as the main fuel fed to the blast furnace and therefore of the greatest impact on the final product cost. AHMSA contemplated within its strategic plan, the reduction in the production of its coking plants derived from the natural aging of its furnaces, consequently it is pending the shortage of coke for productions higher than 2.6 MMT of liquid iron. In response to this, and faced to the true need of diminishing the production costs in the process of making pig iron, new practices have been implemented in the use of complementary fuels to partially substitute the metallurgical coke as an energy source for the blast furnace process. The use of natural gas, fuel oil and the gradual increase of the temperature of hot blow, have strongly impacted the metallurgical coke consumption, lowering it considerably and diminishing the costs per ton of pig iron in blast furnace No. 5. Another important issue, is the utilization of coke fines resulting form the sieving of the same, directly fed to the furnace load. This practice reduced the coke consumption, and most of all, the output of our coking plants was increased on being utilized at the maximum coke production

En primer lugar, se analizan las crecientes necesidades de financiación de la economía española durante el pasado ciclo expansivo y el decisivo papel de las instituciones financieras en la canalización del ahorro externo. Posteriormente, se analiza la evolución de la presencia territorial de las cajas de ahorro y de las cooperativas de crédito, así como la distribución de sus operaciones activas y pasivas. El análisis se realiza diferenciando dos períodos, uno desde el inicio de los noventa hasta el verano de 2007, momento en el que se inicia la crisis, y un segundo período, desde el cuarto trimestre de 2007 hasta la actualidad. / This paper examines the impact that the international economic and financial crisis is having on the behaviour of Spanish social banking institutions, particularly in their funding and localization strategies. First of all, we analyse the growing net borrowing of the Spanish economy in the former economic expansion cycle and how the national financial institutions were the primary source of foreign financing. Secondly, we analyse the evolution of territorial localization of saving banks and credit co-operatives, and of their lending and borrowing transactions. In this analysis we are going to difference two periods: since the beginning of nineties until August 2007, the start of the international financial, and a second period since the fourth quarter 2007 until now.

    Full Text Available The article presents a specific proposal of reading the Logic of Sense,which – referring to the philosophy of Kant – I call architectural. Architecturalreading consists in the simultaneous analysis of philosophical theory and the formalstructure of the work. Although this technique may be referred to a number ofclassic works, Logic’s case appears to be unique, as suggested by the author when henames each of the 34 chapters ‘series’ as a pivotal concept for the theory. ThereforeLogic is deliberately self-reflexive, which means that the structure of chapters andparagraphs, the nature of philosophical concepts, and even the difficulty in readingare justified by contents. Finally, it appears that Logic is constructed as a puzzlewaiting to be solved in accordance with subjective questions and problems of thereader. I intentionally do not present any particular proposal of reading, I merelytry to provide a ‘strategy’. In this sens, the article is a prolegomena to the properreading of the Logic of Sense.

Su modelo de banca “minorista”, centrada en la cercanía al cliente, se ha visto acompañado en los últimos años de un fuerte proceso de expansión geográfica que ha supuesto un sobredimensionamiento de su red de sucursales. Sin embargo, como consecuencia de las actuales circunstancias de la economía española en general, y del sistema bancario en particular, dicha estrategia de desarrollo interno no parece sostenible, siendo necesario que se produzca un redimensionamiento del sector, para ver recuperada la confianza en el sistema y para que éste vuelva a ser considerado como uno de los más solventes del mundo.

NO{sub x} emissions will increase from 6000 t/a in 2005 to 24,000 t/a in 2025, and CO{sub x} will rise from 3.4 million t/a in 2005 to 12.7 million t/a in 2025. The cost of generation will be affected by changes in the energy matrix, and the use of natural gas will predominate. In absolute values it will increase from $648 million USD in 2005 to $2273 million USD in 2025. The cost will depend on an use up to 70% of natural gas. The proposed goals of the Systemic Planning focused on: a) reduce own uses of electricity during generation, b) reduce electric own uses and electric losses during transmission and distribution, c) reducing the growth of electric consumption in the industrial sector, and d) increasing the share of geothermal energy. In a comparison of the Systemic Planning System with the Prospective, increasing in 500 MW the geothermal installed capacity will increase the investment cost, but the balance of net exports, carbon credits and reduced consumption of natural gas indicates a total savings of $11 billion USD and a decrease of 2.3 million tons of CO{sub x}.

    It is possible, and besides logic, the integration of programs such as the electric energy saving and an environmental management system. In managing the consumption and the demand of the electric service, there is an effect on the pollutants emitted for the generation. It is clear that the user in not, and can not be, responsible for the type of fuel used but its importance in project planning is out of question. In its turn the central point of the environmental management system, consists in identifying the main effects on the environment caused by its activities, services and products, as well as the current or potential control level of the enterprise on them. Such identification and further evaluation took us at JVC Industrial de Mexico, to integrate conceptually and operationally such programs. The commitment with the Management was concentrated and strengthened resulting in a fuller consciousness of resource administration.

A su vez el punto central del sistema de administracion ambiental, consiste en identificar los principales efectos en el medio ambiente causados por sus actividades, servicios o productos, asi como el nivel de control actual o potencial de la empresa sobre ellos. Dicha identificacion y la posterior evaluacion nos llevo, en JVC Industrial de Mexico, a integrar tanto conceptual como operacionalmente dichos programas.

    alternating current terminal is recovered from the power lines and there will not be generation restrictions because of the unavailability of alternating current power lines; the achieved reliability is not evaluated, but it will be another benefit. The other option proposed for the project of utilization of power lines with direct current, consists in modifying or using the tie that will be constructed for the Rio Escondido Thermal Electric Station to the Northern Zone and that will operate in parallel with the alternating current network. This project provides the benefits of saving losses of about 20 MW. It is also achieved the increase in effective transmission capacity towards the Northern Zone, due to the fact that it will be Also available a controlled power mean, which facilitates the dispatch functions and re-distribution of power flows in the alternating current network. This tie is proposed of 500 MW operating in bi-polar form at least of 400 KV and reaching up to the Chihuahua Zone, allowing besides the re-dispatching of units to the Northern Zone in counting with greater capacity of effective transmission. The saving in re-dispatching could be significative; additionally, this tie will free transmission capacity from the Coal Power Stations towards the Monterrey Zone. This paper does not get deeper into the advantages regarding the dynamic behavior of the electric system in operating these ties in direct current, but they are not less important, since they can contribute with great benefits to the system during disturbance or emergency conditions.

    During architectural conception phase,building maintenance problematic is mostly a result of the unintentional use of preconceived architectonical solutions rather than a consequence of a specific influence of maintenance requirements.Hardly the architect in the act of design understands the importance of these solutions in the service life span of a building.Being aware of this,is it possible for the architect to be supplied with a decision support system that allows him to consider the implications of building maintenance since the early design phases? Having awareness of this problem and its consequences in the early design phases a research project was started at the Faculty Engineering of the University of Oporto(FEUP),under which the implications of building maintenance in the act of architectural design is studied.This article presents the methodology developed to identify the needs of maintenance of buildings based on a DSS-decision support system that provides simple tools the architect can use in design phase.This methodology is based on decomposition of building parts-Elements Source of Maintenance ESM-,and subsequently,a set of functional requirements that determine the performance regarding building maintenance on account of architectural decisions.Relevant maintenance actions are defined:Inspection,Pro-action,Cleaning,Correction,Replacement,Legal enforcement,Limits of use.One can thus set up a relationship between the act of design and its performance framework based on behavior,intervention and the ownership of the work of architecture.Using a Multicriteria Analysis (MCA) a qualitative evaluation of different options based on maintenance requirements accomplishment.Conclusions on the importance of architectural conception concerning the building maintenance were clearly arrived at and the utility of the developed decision support tool was also highlighted.

This paper proposes a design process for a graphic design graduate class using activity theory as a theoretical background. This design process consists of three phases to solve the design problems within diverse design projects. Each phase was examined in terms of how the elements of activity theory could apply to the design process. As a research me...

    Full Text Available The continous appearance of new materials, the general tendency towards lighter structural charges, the increased personal welfare levels, tile extended use of mechanical equipments for environmental conditioning in most of the housings presently being constructed, and the incessant and considerable increase of the organic fuel costs have given rise to a new study, both in scope and precision, of the physical and construction basis of the fundamental problems of living spaces. In addition to the financial and engineering aspects of the separate installations the problem is here approached through three different angles: I. Analysis of the thermophysical characteristics of the materials and structural elements that define and quantify the insulating capacity of these. II. Constructive arrangements suitable for carrying out the architectural projects of the construction elements, in order to obtain their maximum efficiency, as regulators of the negative environmental influences. III. A relative study of existing national and foreign regulations of the hygrothermal needs that the elements and structural spaces must meet to achieve the required comfort within the envisaged budget. Each of the above mentioned items will be dealt with in this Journal from this number onwards.La continua aparición de nuevos materiales, la tendencia general al aligeramiento de las cargas estructurales, el incremento de los niveles individuales de bienestar, la extensión de los equipos mecánicos de acondicionamiento ambiental a la mayoría de las viviendas actualmente en construcción, y e! ininterrumpido y sustancial crecimiento en los costos de los combustibles orgánicos, han dado lugar al replanteamiento, en extensión y profundidad, de las bases físico-constructivas en las que descansa la problemática funcional de los recintos habitacionales.

    alternating current terminal is recovered from the power lines and there will not be generation restrictions because of the unavailability of alternating current power lines; the achieved reliability is not evaluated, but it will be another benefit. The other option proposed for the project of utilization of power lines with direct current, consists in modifying or using the tie that will be constructed for the Rio Escondido Thermal Electric Station to the Northern Zone and that will operate in parallel with the alternating current network. This project provides the benefits of saving losses of about 20 MW. It is also achieved the increase in effective transmission capacity towards the Northern Zone, due to the fact that it will be Also available a controlled power mean, which facilitates the dispatch functions and re-distribution of power flows in the alternating current network. This tie is proposed of 500 MW operating in bi-polar form at least of 400 KV and reaching up to the Chihuahua Zone, allowing besides the re-dispatching of units to the Northern Zone in counting with greater capacity of effective transmission. The saving in re-dispatching could be significative; additionally, this tie will free transmission capacity from the Coal Power Stations towards the Monterrey Zone. This paper does not get deeper into the advantages regarding the dynamic behavior of the electric system in operating these ties in direct current, but they are not less important, since they can contribute with great benefits to the system during disturbance or emergency conditions.

  9. The Experience of Consciousness: The Architectonic of the Grundlage der gesammten Wissenschaftslehre

    Directory of Open Access Journals (Sweden)

    Ronnie Mather

    2009-12-01

    Full Text Available The key work of the early Johann Gottlieb Fichte (at least in regard to the interpretation of his system is the Grundlage ser gesammten Wissenschaftslehre [Foundation of the Entire Doctrine of Science] of 1794-95. The very circumstances of its publication ensure that it is a rather terse and disjointed statement of Fichtean philosophy. It consists of a very short preface, a “famous” (at least in the sense of actually being read section devoted to first principles, the so-called “basic propositions of the entire doctrine of science,” and eight discourses of widely diverging length. The first discourse, devoted to the “theoretical” Wissenschaftslehre is one and a half times the length of the other seven. The third, fourth, fifth, sixth and eighth are barely a few pages long. It is an extremely peculiar work and not merely due to the circumstances of its publication. Its very argumentative structure threatens to trap the reader in forming hasty and preliminary judgements on the exact nature of the philosophical claims being made, and, quite specifically, those philosophical claims which might be ascribed to the author himself. The following contends that lack of attention to the structure of a work that, admittedly, exhibits very little in an overt fashion has led to wholesale confusion about the early system and its philosophical intent. Specifically, that too much attention has been paid to the famous section on grounding principles, and, furthermore, that attention only to these sections will lead to fundamental confusion and misunderstanding. This paper will attempt to examine this peculiar Fichtean text via the readings made by Dieter Henrich and Frederick Neuhouser, respectively.

    Cebus monkeys stand out from other New World monkeys by their ability to perform fine hand movements, and by their spontaneous use of tools in the wild. Those behaviors rely on the integration of somatosensory information, which occurs in different areas of the parietal cortex. Although a few studies have examined and parceled the somatosensory areas of the cebus monkey, mainly using electrophysiological criteria, very little is known about its anatomical organization. In this study we used SMI-32 immunohistochemistry, myelin, and Nissl stains to characterize the architecture of the parietal cortical areas of cebus monkeys. Seven cortical areas were identified between the precentral gyrus and the anterior bank of the intraparietal sulcus. Except for areas 3a and 3b, distinction between different somatosensory areas was more evident in myelin-stained sections and SMI-32 immunohistochemistry than in Nissl stain, especially for area 2 and subdivisions of area 5. Our results show that cebus monkeys have a relatively complex somatosensory cortex, similar to that of macaques and humans. This suggests that, during primate evolution, the emergence of new somatosensory areas underpinned complex manual behaviors in most Old World simians and in the New World cebus monkey. J. Comp.

    Human inferior parietal lobule (IPL) plays a key role in various cognitive functions. Its functional diversity, including attention, language, and action processing, is reflected by its structural segregation into 7 cytoarchitectonically distinct areas, each with characteristic connectivity patterns. We hypothesized that commonalities of the cytoarchitectonic, connectional, and functional diversity of the IPL should be reflected by a correlated transmitter receptor-based organization. Since t...

    Full Text Available The objective of this text is to examine proposals for a coursebook of Portuguese language for high school students, based on the reading of verb-visual texts. Supported by the concepts of “text” and “architectonics” from the theory of Bakhtin and the Circle, and considering how the study of language seeks to understand the production of meaning in a cultural, social and historical dimension, we discuss the orientation given to the written production of publicity texts. The theoretical and methodological approaches used in the didactic sequences allow the students to articulate different texts, verbal and visual, so that they can assume an ethical position in the real world.

    This paper is a proposal for the systematization of the process of bioclimatic design, particularly in its analytical stage. It is based on the proposals of the classic researchers such as: Olgyay, Givoni and Szokolay, but also in new contributions like those of Yeang. Nevertheless, it is about a methodology adapted to the specific requirements of teaching and research that are carried out in the Bioclimatic Design Laboratory of the Universidad Autonoma Metropolitana, Azcapotzalco Unit. What is presented here is a part of a very ample research project that intends to develop or to structure a design methodology that incorporates the environmental variables related to man and architecture: of course, with the objective of facilitating the designer work so that the final architectonic product has a more harmonic response to the environment, offers conditions of integral well- being to its occupants and be is efficient in the handling of the resources. It also looks for the definition of the necessary analysis, design and evaluation tools, necessary in order that the application of the methodology is clear, simple and can be carried out by any designer, even if he does not have a wide knowledge of bioclimatic design.

  7. ECO DESIGN IN DESIGN PROCESS

    PRALEA Jeni

    2014-05-01

    Full Text Available Eco-design is a new domain, required by the new trends and existing concerns worldwide, generated by the necessity of adopting new design principles. New design principles require the designer to provide a friendly relationship between concept created, environment and consume. This "friendly" relationship should be valid both at present and in the future, generating new opportunities for product, product components or materials from which it was made. Awareness, by the designer, the importance of this new trend, permits the establishment of concepts that have as their objective the protection of present values and ensuring the legacy of future generations. Ecodesig, by its principles, is involved in the design process, from early stage, the stage of product design. Priority objective of the designers will consist in reducing the negative effects on the environment through the entire life cycle and after it is taken out of use. The main aspects of the eco-design will consider extending product exploitation, make better use of materials, reduction of emission of waste. The design process in the "eco"domein must be started by selecting the function of the concept, materials and technological processes, causing the shape of macro and micro geometric of the product through an analysis that involves optimizing and streamlining the product. This paper presents the design process of a cross-sports footwear concept, built on the basis of the principles of ecodesign

  20. Tank design

    International Nuclear Information System (INIS)

    This paper reports that aboveground tanks can be designed with innovative changes to complement the environment. Tanks can be constructed to eliminate the vapor and odor emanating from their contents. Aboveground tanks are sometimes considered eyesores, and in some areas the landscaping has to be improved before they are tolerated. A more universal concern, however, is the vapor or odor that emanates from the tanks as a result of the materials being sorted. The assertive posture some segments of the public now take may eventually force legislatures to classify certain vapors as hazardous pollutants or simply health risks. In any case, responsibility will be leveled at the corporation and subsequent remedy could increase cost beyond preventive measures. The new approach to design and construction of aboveground tanks will forestall any panic which might be induced or perceived by environmentalists. Recently, actions by local authorities and complaining residents were sufficient to cause a corporation to curtail odorous emissions through a change in tank design. The tank design change eliminated the odor from fuel oil vapor thus removing the threat to the environment that the residents perceived. The design includes reinforcement to the tank structure and the addition of an adsorption section. This section allows the tanks to function without any limitation and their contents do not foul the environment. The vapor and odor control was completed successfully on 6,000,000 gallon capacity tanks

    The structural response velocities produced by pyroshocks are usually too low to cause structural damage beyond the immediate region of the pyrotechnic device where damage is intended. On the other hand, pyroshocks can cause malfunctions of equipment mounted near the pyrotechnic device, particularly equipment containing microelectronic or ceramic elements. These malfunctions are usually the result of the high frequency content (above 2 kHz) of pyroshocks, and are difficult to design against using conventional analysis procedures. On the other hand, adherence to simple design guidelines, which are summarized, can substantially suppress pyroshock-induced failures of equipment.

    This article is about two important scopes of the Bioclimatical Design (BD), the Social scope and the environmental scope. As an introduction, it is justified the importance of this topic through the association of the BD in the context of sustainability with our country's economic model. The analysis is done under the perspective of effects of the BD on social and environmental scopes. In social scope is used the Cost and Benefit Analysis according to social evaluation. In environmental scope, effects in water, air and ground are studied, but the measurement is done according to the emissions reduction of CO{sub 2} on atmosphere because of the earn on energy consumption. The results of the measurement of this effects are related with economical costs and benefits, which may show a general view about economical, social and environmental scopes. As conclusions, interest results are show and this is proposed to incorporate them in the economical politics.

El estudio se realiza bajo la perspectiva de los impactos que el DB tiene en el aspecto social y en el ambiental. En lo social, se recurre a la metodologia del Analisis Costo-Beneficio para evaluacion Social, en lo ambiental, aunque se tocan los puntos de impacto en aire, agua y uso de suelo, la medicion del impacto se realiza con base en la disminucion de emisiones de CO{sub 2} a la atmosfera por el ahorro en el consumo de energia electrica. Los resultados de la medicion de impactos se cruzan con los costos y beneficios economicos, para presentar un panorama completo en cuanto a aspectos economicos, sociales y ambientales.

In particular, we are interested in the consequence of changes of tax incentives on that behavior, Following a revision of theoretical aspects of saving behavior of firms, we analyze how tax variables affect internal and/or external financing decisions of firms. From empirical estimations, we can elude that the theory of capitalization of taxes, which states that the cost of capital is the transmission mechanism of tax changes, is not verified during the analyzed period, Indeed, the cost of capital, that aflects negatively the reinvestment profit rate, does not appear to be a significant variable of the model.

  19. Mechanical Design

    International Nuclear Information System (INIS)

    The particle beam of the SXR (soft x-ray) beam line in the LCLS (Linac Coherent Light Source) has a high intensity in order to penetrate through samples at the atomic level. However, the intensity is so high that many experiments fail because of severe damage. To correct this issue, attenuators are put into the beam line to reduce this intensity to a level suitable for experimentation. Attenuation is defined as 'the gradual loss in intensity of any flux through a medium' by (1). It is found that Beryllium and Boron Carbide can survive the intensity of the beam. At very thin films, both of these materials work very well as filters for reducing the beam intensity. Using a total of 12 filters, the first 9 being made of Beryllium and the rest made of Boron Carbide, the beam's energy range of photons can be attenuated between 800 eV and 9000 eV. The design of the filters allows attenuation for different beam intensities so that experiments can obtain different intensities from the beam if desired. The step of attenuation varies, but is relative to the thickness of the filter as a power function of 2. A relationship for this is f(n) = x02n where n is the step of attenuation desired and x0 is the initial thickness of the material. To allow for this desired variation, a mechanism must be designed within the test chamber. This is visualized using a 3D computer aided design modeling tool known as Solid Edge.

    International Nuclear Information System (INIS)

    The feasibility of constructing a TeV region electron-positron linear collider in Japan is discussed. The design target of the collider is given as follows: Energy, 1 TeV + 1 TeV; luminosity, 1032-1033/cm2/s; total length, 25km; electric power, 250MW; energy dispersion, 1%-10%; the start of the first experiment, early 1990s. For realizing the above target, the following research and developmental works are necessary. (a) Development of an acceleration tube with short filling time and high shunt resistance. (b) Short pulse microwave source with high peak power. (c) High current, single bunch linac. (d) Beam dynamics. As for the acceleration tube, some possibility is considered: For example, the use of DAW (Disk and Washer) which is being developed for TRISTAN as a traveling-wave tube; and the Jungle Gym-type acceleration tube. As a promising candidate for the microwave source, the Lasertron has been studied. The total cost of the collider construction is estimated to be about 310 billion yen, of which 120 billion yen is for the tunnel and buildings, and 190 billion yen for the accelerator facilities. The operation cost is estimated to be about 3 billion yen per month. (Aoki, K.)

    This paper presents the analysis of the tools commonly utilized in Bioclimatic Design, for the achievement of humidity an temperature comfort conditions in architectonic spaces. The analysis was performed by means of field studies and experimentally for different sport activities, carried out in spaces designed for each purpose. In the experimental part, inside ambient temperature and relative humidity were measured in the different spaces where sport activities were conducted, such as calisthenics, dance, judo, wrestling, weight lifting, boxing, basket-ball, volley-ball, gymnastics and fencing. At the same time an inquiry was conducted among their occupants in respect to the thermal sensation they experimented while conducting such activities. The results obtained in the inquiry were compared with the results reported by other researchers, by means of tables and psychometric diagrams as optimum values for temperature comfort. As a conclusion it was decided that the graphic and mathematical methods analyzed, are based on a sedentary activity, therefore in using them for the design of spaces for different activities uncomfortable conditions are experimented with the consequential necessity of air conditioning, which implies energy consumption and the corresponding expenditure, lastly it is necessary to adapt these tools, that is, consider the activity that is going to be performed in the buildings.

    The efficient handling of the economic and natural resources of the municipalities, is nowadays so much complex, that it requires a formal planning. In the public service of potable water supply, two fundamental approaches are conjugated to consider: the rational use of the water resource and the efficient use of the electrical energy, for its extraction from the underground deep reservoirs. In the paper that is presented, the individual features of the previous matters are described and the positive results in a municipality of the Guanajuato's Low Lands (Bajio ), where already the dual objectives are obtained and that with a more professional municipal hydraulic planning, these will be permanent, with the inherent benefit towards the population. [Spanish] El manejo eficiente de los recursos economicos y naturales de los municipios, es hoy en dia cada vez mas complejo, que requiere una planeacion formal. En el servicio publico de abastecimiento de agua potable, se conjugan dos enfoques primordiales a considerar: el uso racional del recurso agua y la utilizacion eficiente de la energia electrica, para su extraccion de los acuiferos subterraneos profundos. En el trabajo que se presenta, se describen las particularidades de lo anterior y los resultados positivos en un municipio del Bajio guanajuatense, donde ya se logran los objetivos duales y que con una planeacion hidraulica municipal mas profesional, estos seran permanentes, con el beneficio inherente hacia la poblacion.

    The cement plant Cruz Azul S.C.L. is located in the center of the Mexican republic at 70 km north of the capital. Nowadays the Direction of Cementos Cruz Azul has implemented measures allowing to reduce their production costs. The optimization department found a great area of opportunity at the ventilators of the plant. The ventilators are used in different stages of the process and their flow was normally controlled by means of dampers -due to the high costs of the initial investment and that of maintenance of the speed variation technology which in its majority used direct current equipments. In this case it existed the possibility of making a successful application in two large ventilators, with motors of 1000 HP fed in medium tension (4160 v) in our calcination unit Num. 8. This document shows the development of this project from its initial analysis to its application and results.

    A number of empirical studies have concluded that capital is internationally immobile. This result contradicts the empirical observation that a large volume of capital is traded every day in international capital markets. Is capital internationally mobile or not? This is the well known Feldstein-Horioka paradox. By estimating savings retention coefficients, we find that in Mexico, capital was immobile during the 1960’s and 1970’s but mobile during the 1980’s and 1990’s.

Pervasive games are computer games, played using the city as a game board and often using mobile phones with GPS. Some contextual design methods exist, but we propose an approach...... that calls for the designer to conceptualise and perform ideas in-situ, that is on the site, where the game is supposed to be played. The problem was to design a creativity method that incorporated in-situ design work and which generated game concepts for pervasive games. The proposed design method, called...... sitestorming, is based on a game using Situationistic individual exploration of the site and different types of game cards, followed by a joint evaluation of the generated ideas. A series of evaluations showed that the designers found the method enjoyable to use, that the method motivated idea generation...

    In order to succeed in today's global, competitive market, companies need continuous improvements in their product development processes. These improvements should result in expending fewer resources on the design process while achieving better quality. Automating the design process reduces resources needed and allows designers to spend more time on creative aspects that improve the quality of design. For the last three decades, engineers and designers have been searching for better ways to automate the product development process. For certain classes of design problems, which cover a large portion of real world design situations, the process can be automated using knowledge-based systems. These are design problems in which the knowledge sources are known in advance. Using techniques from Knowledge-Based Engineering, knowledge is codified and inserted into a knowledge-based system. The system activates the design knowledge, automatically generating designs that satisfy the design constraints. To increase the return on investment of building automated design systems, Knowledge management methodologies and techniques are required for capturing, formalizing, storing, and searching design knowledge.

    International Nuclear Information System (INIS)

    Nuclear fuel design is strictly dependent on reactor type and experiences obtained from performance of nuclear fuels. The objectives of the design are reliability, and economy. Nuclear fuel design requires an interdisciplinary work which has to cover, at least nuclear design, thermalhydraulic design, mechanical design, and material properties.The procedure of design, as describe in the quality assurance, consist of a number of steps. The most important parts are: Design description or inputs, preliminary design, detailed design and design output, and design verification. The first step covers objectives and requirements, as defined by the customer and by the regulatory authority for product performance,environmental factors, safety, etc. The second describes assumptions and alternatives, safety, economy and engineering analyses. The third covers technical specifications, design drawings, selection of QA program category, etc. The most important form of design verification is design review by qualified independent internal or external reviewers. The scope of the review depends on the specific character of the design work. Personnel involved in verification and review do not assume prime responsibility for detecting errors. Responsibility for the design remains with the personnel involved in the design work

In addition, security problems were minimized and a saving was realized in circuit cost. The custom CMOS IC's were designed at less than half the cost of designing with conventional techniques. In addition to the computer aided design, the prototype fabrication and testing capability provided by the semiconductor development laboratory and microelectronics computer network allows the circuits to be fabricated and evaluated before the designs are transferred to the commercial semiconductor manufacturers for production. The Sandia design and prototype fabrication facilities provide the capability of complete custom integrated circuit development entirely within the ERDA laboratories

  14. Software Architecture Design Reasoning

    Science.gov (United States)

    Tang, Antony; van Vliet, Hans

    Despite recent advancements in software architecture knowledge management and design rationale modeling, industrial practice is behind in adopting these methods. The lack of empirical proofs and the lack of a practical process that can be easily incorporated by practitioners are some of the hindrance for adoptions. In particular, the process to support systematic design reasoning is not available. To rectify this issue, we propose a design reasoning process to help architects cope with an architectural design environment where design concerns are cross-cutting and diversified.We use an industrial case study to validate that the design reasoning process can help improve the quality of software architecture design. The results have indicated that associating design concerns and identifying design options are important steps in design reasoning.

    This study explored the ways that design has been experienced by professionals in a variety of disciplines. Transcripts from semi-structured interviews with professional designers about concrete design experiences, and reflections and meanings associated with those experiences, comprised the data that were analyzed through a phenomenographic lens. The results of this study included six qualitatively different ways that design has been experienced. Represented in a hierarchical form, from less comprehensive to more comprehensive, these categories of description included: Design is (1) evidence-based decision-making, (2) organized translation, (3) personal synthesis, (4) intentional progression, (5) directed creative exploration, and (6) freedom. This hierarchy emerged from considering the relationships between the categories of description. An additional outcome of this study was the generation of themes of expanding awareness, including the role of the problem, the role of ambiguity, the task endpoint, and the task outcome. The results of this study inform the literature on design and have implications for design practice and education. Specifically, the results expand the ways that design can be viewed, building on and suggesting new lenses for describing and defining design. The results revealed areas of similarities and differences in the ways design is viewed by professionals, suggesting areas for which common ground can be built across disciplines, as well as highlighting differing ways of experiencing design that exist even within fields. The results also point to additional ways to view design expertise beyond the specific skills and technical knowledge that designers bring to tasks. The implications for design practice and education center on the idea of facilitating designers in being aware of their own ways of viewing and experiencing design as well supporting them in expanding their awareness to include how others view and experience design.

    International Nuclear Information System (INIS)

    Improved design techniques are needed to achieve high reliability at minimum cost. This is especially true of space systems where lifetimes of many years without maintenance are needed and severe mass limitations exist. Reliability must be designed into these systems from the start. Techniques are now being explored to structure a formal design processes that will be more complete and less expensive. The intent is to integrate the best features of design, reliability analysis, and expert systems to design highly reliable systems to meet stressing needs. Taken into account are the large uncertainties that exist in materials, design models, and fabrication techniques. Expert systems are a convenient method of integrating into the design process a complete definition of all elements that should be considered and an opportunity to integrate the design process with reliability, safety, test engineering, maintenance, and operator training. The approach being pursued to accomplish the design reliability engineering process is described. Potential benefits using the design reliability engineering approach are discussed. Design reliability engineering can become a very powerful and cost-effective design tool. The methodology takes advantage of recent developments in computers, expert systems, and reliability engineering to cost-effectively enhance the design process

    There are many examples of cards used to assist or provide structure to the design process, yet there has not been a thorough articulation of the strengths and weaknesses of the various examples. We review eighteen card-based design tools in order to understand how they might benefit designers....... The card-based tools are explained in terms of five design dimensions including the intended purpose and scope of use, duration of use, methodology, customization, and formal/material qualities. Our analysis suggests three design patterns or archetypes for existing card-based design method tools...... and highlights unexplored areas in the design space. The paper concludes with recommendations for the future development of card-based methods for the field of interaction design....

    When designing games with learning purposes used in a classroom, there often occur problems about the lack of learning content or the lack of game contents. Other disadvantages of existing educational games are the difficulty to provide a continual balance between the challenge and the pupils......’ skill to control and solve the given task. In this paper we suggest three different perspectives that need to be communicated across in order to design a useful educational game: teachers, pupils and game designers. It is our intention with this paper to suggest some design principles for educational...... games, and to integrate teachers, pupils and game designers needs and requirements. To set up these design principles for educational games we have used a holistic perspective. This means that the design principles must be seen in coherence within the social and physical environment. The design...

  18. Security by Design

    International Nuclear Information System (INIS)

    Security by design can reduce the intrinsic vulnerability of nuclear facilities while minimising costs and disruption to operations. The fundamental processes of a nuclear facility should be designed from the start to give the same priority to nuclear security objectives as to nuclear safety. Vital Areas should be designed out, minimising the need for protective security and reducing the risk from insiders. This requires a proactive approach, involving engineers, security managers, safety specialists and operators to optimise the benefits from the intrinsic features of the processes, materials and structures. A robust, threat tolerant design is required. In some areas, measures included in the design to improve nuclear safety will also assist security. In others, a design solution needs to be sought that will minimise conflicting requirements. Security by design requires appropriate organisational commitment and culture to enable full integration of the design for operations, security, safety and safeguards. (author)

    International Nuclear Information System (INIS)

    In the spring of 1985, the Department of Energy (DOE) directed the Design Center to take a lead responsibility in assessing the engineering feasibility of a very compact tokamak experiment with copper coils. Following this assessment, the Design Center studied the Ignitor concept at the request of DOE and arrived at a design configuration. Many features of this configuration have been incorporated into the national baseline conceptual design for a Compact Ignition Tokamak (CIT). The Design Center continued to participate in the mirror program by contributing to the Minimars design effort, a two-year program to develop and describe an attractive tandem mirror reactor concept. The Design Center's principal role is in configuration definition of the candidate concepts. The Design Center continues to lead the engineering activities for the International Tokamak Reactor program. Advanced commercial tokamaks were studied by the Design Center as part of the Tokamak Power Systems Studies project coordinated by the DOE Office of Fusion Energy. The Design Center also provided design integration of the US effort. A cost accounting system that is applicable to all magnetic fusion reactor design studies was developed and applied to different confinement concepts and types of projects. The system provides the structure for development of a fusion cost database and validated cost estimating procedures

  7. Designing synthetic biology.

    Science.gov (United States)

    Agapakis, Christina M

    2014-03-21

    Synthetic biology is frequently defined as the application of engineering design principles to biology. Such principles are intended to streamline the practice of biological engineering, to shorten the time required to design, build, and test synthetic gene networks. This streamlining of iterative design cycles can facilitate the future construction of biological systems for a range of applications in the production of fuels, foods, materials, and medicines. The promise of these potential applications as well as the emphasis on design has prompted critical reflection on synthetic biology from design theorists and practicing designers from many fields, who can bring valuable perspectives to the discipline. While interdisciplinary connections between biologists and engineers have built synthetic biology via the science and the technology of biology, interdisciplinary collaboration with artists, designers, and social theorists can provide insight on the connections between technology and society. Such collaborations can open up new avenues and new principles for research and design, as well as shed new light on the challenging context-dependence-both biological and social-that face living technologies at many scales. This review is inspired by the session titled "Design and Synthetic Biology: Connecting People and Technology" at Synthetic Biology 6.0 and covers a range of literature on design practice in synthetic biology and beyond. Critical engagement with how design is used to shape the discipline opens up new possibilities for how we might design the future of synthetic biology. PMID:24156739

  16. Preparing design students for strategic design

    Directory of Open Access Journals (Sweden)

    Jørgen Rasmussen

    2012-08-01

    Full Text Available This paper deals with how the visual approach from a design process can help inform companies about future opportunities at a strategic level. The paper follows an innovation project where design students worked with five companies at a 1-day workshop and with one company through a 2-week project. In both processes the students worked visually with mapping and making sense of large amounts of data that may influence the company’s strategy. They also synthesized these finding by creating conceptual suggestions for the company’s future products. This paper discusses the lessons learned from the innovation project and reflects on which new knowledge, methods and techniques designers should be aware of when participating in multidisciplinary strategic processes and new educational initiatives. This paper shows how the design profession’s traditional visual tools and methods for concept development can be used to facilitate discussions for companies facing strategic challenges. It also underlines the importance of rethinking design skills and communication when moving into strategic processes.

    Good lighting is essential to a building. An effective design is not just about introducing light into a space, but rather an appreciation of how the space will be used. A good lighting design is so intertwined with the building that it is only noticed in its absence. This book introduces the tools of the lighting designer and explains how to produce a lighting design for a home. Looking at the nature of light and introducing different lamps and light fittings available, it explains the basics of lighting design and how to provide atmosphere through the play of light and shadow.

    2006-12-01

    Full Text Available Sustainable design is fundamentally a subset of good design. The description of good design will eventually include criteria for the creation of a healthy environmentand energy efficiency. These goals will be achieved by an emergent paradigm of design practice: integration. At every level design interests will come together to facilitate common goals for the creation of a rewarding present and a healthy future. Interdisciplinary design teams will flourish. Inter-accommodating and fluidly communicating political structures will grow. Coalescing social values and economic forces will propel integrated strategies. Unique and innovative solutions will increasingly become the objective. One eventual outcome of this integrated or sustainable design practice will be the development of buildings that produce more energy than they consume.

  11. PRISM Spectrograph Optical Design

    Chipman, Russell A.

    1995-01-01

    The objective of this contract is to explore optical design concepts for the PRISM spectrograph and produce a preliminary optical design. An exciting optical configuration has been developed which will allow both wavelength bands to be imaged onto the same detector array. At present the optical design is only partially complete because PRISM will require a fairly elaborate optical system to meet its specification for throughput (area*solid angle). The most complex part of the design, the spectrograph camera, is complete, providing proof of principle that a feasible design is attainable. This camera requires 3 aspheric mirrors to fit inside the 20x60 cm cross-section package. A complete design with reduced throughput (1/9th) has been prepared. The design documents the optical configuration concept. A suitable dispersing prism material, CdTe, has been identified for the prism spectrograph, after a comparison of many materials.

  4. Rich Design Research Space

    Directory of Open Access Journals (Sweden)

    Birger Sevaldson

    2008-10-01

    Full Text Available This paper introduces and discusses a Rich Research Space as an inclusive methodological framework and scaffold for research-by-design. The Rich Research Space especially addresses the issue of richness in design processes and design-led research. There is a general trend towards increased complexity in design processes, caused on one hand by the increasing depth and width in the use of design media and methods, and on the other hand by the increasing complexity and interdependency of society due to globalisation. These issues confront the designer-researcher with new challenges. This paper formulates a research strategy for research-by-design in fields that have a high degree of richness in the use of media, the amount of information, and the methods involved. The Rich Research Space concept proposed takes into account the physical, social, and cultural spaces, and the virtual and visual media spaces in which the research-by-design takes place. The concept takes the form of a specific integral approach to design, and a holistic theoretical mindset. It embraces many types of investigation, from analytical to intuitive. The Rich Research Space provides a flexible framework within which the complexity of research-by-design can be interrelated, discussed, and reflected upon. Potentially, it can create a more involved role for the designer-researcher, a role that allows contributions towards the resolution of ever more pressing issues in our society. This approach is currently one of a limited number of possible frameworks that the design professions can utilize in order to make a difference in a world of at times overwhelming complexity. The concept of the Rich Research Space is discussed with reference to an art installation called Barely.Keywords: Research by design, collaborative design, complexity, creativity, research methods.

  5. Children Designing Serious Games

    Directory of Open Access Journals (Sweden)

    J.C. Read

    2013-03-01

    Full Text Available It has long been a tradition in interaction design to involve users in order to better capture user needs and preferences. The involvement of children as informants and design partners is well documented for interaction design but its use in serious games design is much less reported. Where children are contributing to the design of learning materials their knowledge may be incomplete. This paper reports on the organisation of, and the deliverables from, a participatory design activity with children in which they were charged with designing a game for children in another continent. The study found that children predominantly focussed on the learning aspects of the serious game during their design activities but they were also able to consider some of the game aspects. They demonstrated understanding of instruction but were less aware of some of the other aspects of learning including feedback on understanding. Involving children in the design of the serious game lead to some nice insights that were included in the game that was subsequently built and shipped. Taking Müller’s third place in HCI as inspiration, the paper concludes with some reflection for how to involve children in serious game design.

  9. Future steam generator designs. Single wall designs

    International Nuclear Information System (INIS)

    The easily removable 'U' tube design style adopted in the UK for the existing PFR Steam Generators, the Replacement Units now in production and for the future CDFR, gives the operator an extremely valuable option in the event of a water/steam leak occurring inside the Steam Generator. He can choose to shut-down, attempt to find the leak, assess damage, repair, revalidate and return to service in situ, or he can elect to remove the defect unit and replace with a 'proven' spare before returning the circuit to power. With the latter approach the resultant outage time is a known entity of about two weeks. If a repair is attempted in situ, predictions of outage time can become a matter of guesswork since one has no 'guaranteed' method of leak location and the assessment of secondary damage may be very time consuming, depending on the size and type of the original leak together with the particular design style of the Steam Generator. A further significant advantage of the removable 'U' tube design concept is that periodic interchanging of bundles with a spare enables routine chemical cleaning and thorough scheduled tube inspections, with specimen tube sample removal if required for monitoring purposes. If necessary, bundle decontamination can be undertaken to assess engineering deterioration to various degrees of thoroughness ranging from 100% equivalent factory final assembly inspection, to partial decontamination operating via a glovebox type of maintenance bag arrangement, examining local points of both shell and tube areas of the bundle. Many lessons from the last five years' experience of PFR will be incorporated into the design of the CDFR and PFR Steam Generators have two very good examples of how the designer can ease or severely handicap the operator in coping with sodium/water leakages. Good, quick access to tube ends is achieved in the existing PFR Evaporator by simply unbolting the steam/water closure head, but on the superheater and reheater hand-caps have

  13. Integrated building design

    Science.gov (United States)

    Sanguinetti, Jennifer

    2005-04-01

    For many years, building design has been a very linear process with owners speaking to architects who then design building shells that they pass along to sub-consultants who must fit their systems into the allotted spaces. While this process has some advantages, it provides little opportunity to optimize systems based on such factors as energy use or occupant comfort. This presentation will focus on the evolution and implications of integrated building design, a method that has provided greater opportunities for interaction between design disciplines and with building users early on in the design process. Integration has resulted in buildings that are more sustainable than typical buildings and that can respond better to the needs of the owner and users. Examples of the application of the process and the resulting buildings will be presented from the view of a design engineer with experience of both processes. Specifically, the potential contribution of an acoustical consultant in the integrated process will be explored.

  14. IMPROVING CONCEPTUAL DESIGN QUALITY

    DEFF Research Database (Denmark)

    Bush, Stuart; Robotham, Antony John

    This paper will consider how Quality Function Deployment (QFD) and Design for Manufacture and Assembly (DFMA) processes can be used to improve the design quality of products at the concept stage. We appreciate that both QFD and DFMA are techniques that have been used for some time by mature product...... quality is maintained in design project work. The projects described have been carried out with products manufactured by small to medium sized enterprises (SME's), where we have found significant opportunities for product improvement. The quantitative nature of DFMA analysis results allows the novice...... continuous improvement of their products. However, we consider that if novice designers are able to successfully utilise design tools like QFD and DFMA and achieve improvements in design quality, then SME’s have no excuses for ignoring the benefits they could bring to their own product development activity....

  16. Assembly tool design

    International Nuclear Information System (INIS)

    The reactor core of the International Thermonuclear Experimental Reactor (ITER) is assembled with a number of large and asymmetric components within a tight tolerance in order to assure the structural integrity for various loads and to provide the tritium confinement. In addition, the assembly procedure should be compatible with remote operation since the core structures will be activated by 14-MeV neutrons once it starts operation and thus personal access will be prohibited. Accordingly, the assembly procedure and tool design are quite essential and should be designed from the beginning to facilitate remote operation. According to the ITER Design Task Agreement, the Japan Atomic Energy Research Institute (JAERI) has performed design study to develop the assembly procedures and associated tool design for the ITER tokamak assembly. This report describes outlines of the assembly tools and the remaining issues obtained in this design study. (author)

    This paper explores innovation and social behaviourist theory in relation to sustainable urban projects in the highly institutionalized public sector (towns). Using empirical data from France, we examine the dynamics of a design process in which unexpected practices generated innovative urban...... design. We show how the fact that the design process did not follow the standard phases of planning meant that the actors redefined themselves in relation to one another. We point out how the absence of urban design plans during a precise phase of an innovative design process drew the actors...... into a movement of collective action, which presupposed the acquisition of a new identity. Ultimately, our objective is to combine social behaviourist theory and innovation theory and to facilitate innovative design in urban projects....

    2012-01-01

    We review adaptive designs for clinical trials, giving special attention to the control of the Type I error in late-phase confirmatory trials, when the trial planner wishes to adjust the final sample size of the study in response to an unblinded analysis of interim estimates of treatment effects. We point out that there is considerable inefficiency in using the adaptive designs that employ conditional power calculations to reestimate the sample size and that maintain the Type I error by using certain weighted test statistics. Although these adaptive designs have little advantage over familiar group-sequential designs, our review also describes recent developments in adaptive designs that are both flexible and efficient. We also discuss the use of Bayesian designs, when the context of use demands control over operating characteristics (Type I and II errors) and correction of the bias of estimated treatment effects.

  20. Conservation by design.

    Root-Bernstein, Meredith; Ladle, Richard J

    2010-10-01

    Conservation researchers are increasingly aware of the need to conduct interdisciplinary research and to engage nonscientists in practical applications of conservation biology. But so far, industrial designers have been left out of such collaboration and outreach efforts. Conservation of wildlife often depends on products such as nest boxes, feeders, barriers, and corridors, all of which have a designed component that is frequently overlooked. Furthermore, many products are adopted without testing on short or long time scales. We argue that the design of products for conservation, and hence their functionality, effectiveness, and value, can be improved through collaboration with industrial designers. We see four key benefits that can arise from interactions with industrial designers: improvement of product quality and value, innovation and improvement in functionality of products, harmonization of conservation products with local values, and development of a psychological biomimesis approach to design. The role of industrial designers in conservation projects would be to improve factors such as product durability, affordability, functionality, and aesthetic appeal to local people. Designers can also help to create multiple product options whose success can be tested in the field. We propose that collaborations with industrial designers can contribute to the development of improvements to existing products and innovations in the practice of animal conservation. PMID:20408866
