Assessing construction and demolition waste on masonry works to avoid future generation

The difficulty of dealing with construction and demolition waste (CDW) on construction sites is not new and continues to be a significant environmental problem. Currently the CDW collection system in Spain is done in a decentralized manner by each sub-contracted company, being necessary to implement effective waste management measures ensuring a correct management and minimization. During the last years several measures have been launched in order to improve and encourage the reuse and recycling of CDW. A widespread solution for CDW recovery is using them as a landscaping aggregate or for road bases and sub-bases. However, measures encouraging onsite prevention still need to be enhanced. This paper studies the major work stage generating CDW and analyses the categories of CDW produced during its execution. For this, several real building sites have been analysed in order to quantify the estimation of CDW generated. Results of this study show that a significant contributor to the CDW generation on building construction sites in Spain are the masonry works. Finally, a Best Practices Manual (BPM) is proposed containing several strategies on masonry works aimed not only at CDW prevention, but also at improving their management and minimization. The use of this BPM together with the Study and Plan of CDW management --required by law--, promotes the environmental management of the company, favouring the cohesion of the construction process organization at all stages giving rise to establishing responsibilities in the field of waste and providing a greater control over the process. Keywords: construction and demolition waste, management, masonry works, good practice measures, prevention.

Análisis de viabilidad para almacenamiento de Co2 en la estructura geológica Villameriel (Palencia)

El presente proyecto lleva a cabo un análisis de la viabilidad de la estructura geológica Villameriel, situada en la provincia de Palencia, para el almacenamiento geológico profundo de CO2. Las dos medidas determinadas para su análisis serán la determinación de la cantidad de CO2 que se puede inyectar en la formación y el comportamiento del mismo en su interior durante los próximos 100 años. Para calcular estas medidas utilizamos la simulación numérica, a través de dos programas de SCHLUMBERGER. El primero, PETREL, diseñando un modelo estático que escenifique las propiedades del medio geológico lo más real posible, llamado modelo estático. El segundo, ECLIPSE300, que simula el comportamiento del fluido según entra en la formación y a lo largo de todo el período de estudio. Como conclusión final llevaremos a cabo un estudio económico que analice el potencial que tiene este proyecto para llevarse a cabo en la sociedad en la que nos encontramos ahora mismo ABSTRACT This project analyzes the viability of Villameriel geological structure, which is situated in Palencia, Spain. There will be two measures to probe it. The first will be to calculate how much amount of CO2 can be stored in this structure, and second will be to see how the CO2 behaves inside the first 100 years. In order to obtain the answers from these questions, Schlumberger programs are used specifically PETREL and ECLIPSE300. This programs work with numerical methods and they simulate a static model and a dynamic model. Static model is created in order to build a geological model with the same properties than in the real life. Dynamic model works to obtain the maximum amount of CO2 that it can be introduced inside storage formation and to know how CO2 will move inside the first 100 years. At the end, an economic study will be done with the objective to know if it would cost money, if there would be profits or no.

Auto component supply chain: a path to global India

Supply chain management works to bring the supplier, the distributor, and the customer into one cohesive process. The Supply Chain Council defined supply chain as ‘Supply Chain: The flow and transformation of raw materials into products from suppliers through production and distribution facilities to the ultimate consumer., and then Sunil Chopra and Meindl, (2001) have define Supply chain management as ‘Supply Chain Management involves the flows between and among stages in a supply chain to maximize total profitability.’ After 1950, supply chain management got a boost with the production and manufacturing sector getting highest attention. The inventory became the responsibility of the marketing, accounting and production areas. Order processing was part of accounting and sales. Supply chain management became one of the most powerful engines of business transformation. It is the one area where operational efficiency can be gained. It reduces organizations costs and enhances customer service. With the liberalization of world trade, globalization, and emergence of the new markets, many organizations have customers and competitions throughout the world, either directly or indirectly. Business communities are aware that global competitiveness is the key to the success of a business. Competitiveness is ability to produce, distribute and provide products and services for the open market in competition with others. The supply chain, a critical link between supplier, producer and customer is emerged now as an essential business process and a strategic lever, potential value contributor a differentiator for the success of any business. Supply chain management is the management of all internal and external processes or functions to satisfy a customer’s order (from raw materials through conversion and manufacture through logistics delivery.). Goods-either in raw form or processed, whole sale or retailed distribution, business or technology services, in everyday life- in the business or household- directly or indirectly supply chain is ubiquitously associated in expanding socio-economic development. Supply chain growth competitive performance and supporting strong growth impulse at micro as well as micro economic levels. Keeping the India vision at the core of the objective, the role of supply chain is to take up social economic challenges, improve competitive advantages, develop strategies, built capabilities, enhance value propositions, adapt right technology, collaborate with stakeholders and deliver environmentally sustainable outcomes with minimum resources.

A supervised cooperative learning system for early detection of language disorders

The Quality of Life of a person may depend on early attention to his neurodevel-opment disorders in childhood. Identification of language disorders under the age of six years old can speed up required diagnosis and/or treatment processes. This paper details the enhancement of a Clinical Decision Support System (CDSS) aimed to assist pediatricians and language therapists at early identification and re-ferral of language disorders. The system helps to fine tune the Knowledge Base of Language Delays (KBLD) that was already developed and validated in clinical routine with 146 children. Medical experts supported the construction of Gades CDSS by getting scientific consensus from literature and fifteen years of regis-tered use cases of children with language disorders. The current research focuses on an innovative cooperative model that allows the evolution of the KBLD of Gades through the supervised evaluation of the CDSS learnings with experts¿ feedback. The deployment of the resulting system is being assessed under a mul-tidisciplinary team of seven experts from the fields of speech therapist, neonatol-ogy, pediatrics, and neurology.

La arquitectura religiosa de Luis Cubillo de Arteaga (1954-1974)

Esta Tesis Doctoral viene a cubrir el vacío existente referido a la arquitectura religiosa de Luis Cubillo de Arteaga, arquitecto conocido fundamentalmente por su aportación a la vivienda social madrileña en los años 50 y 60, pero con una abundante obra sacra. Para ello se ha estudiado la totalidad de su producción, que abarca desde 1954 hasta 1974. La Tesis analiza su arquitectura religiosa desde varios puntos de vista, que incluyen la implantación de los edificios y sus aspectos formales, constructivos y tipológicos, estos últimos especialmente destacados tras las directrices emanadas del Concilio Vaticano II. Previamente se analizan cuatro ámbitos relevantes en la arquitectura religiosa de Cubillo. En primer lugar se estudia la labor de la Dirección General de Asuntos Eclesiásticos, a la que estaba adscrito el arquitecto y para la que realizó sus primeros trabajos. Dentro de ella se expone la evolución del modelo de Seminario entre los años 40 y 60, para analizar la relevancia de la propuesta de Cubillo para el Seminario de Castellón. A continuación se trata la participación de Cubillo en la construcción de la periferia de Madrid, aunque no referida a sus conocidos trabajos sobre vivienda social, sino a los edificios dotacionales. Así mismo se expone una iniciativa hasta ahora inédita de la Comisaría de Ordenación Urbana de Madrid para dotar de centros parroquiales a los nuevos barrios. Un tercer bloque estudia un tema recurrente a finales de los años 50, la integración de las artes en la nueva arquitectura religiosa, propiciada principalmente por José Luis Fernández del Amo. En el caso de Cubillo, las colaboraciones más notables y objeto de estudio en esta Tesis, fueron las realizadas con los artistas Arcadio Blasco y José Luis Sánchez. Por último se describe la situación de la iglesia madrileña posconciliar y su plan de construcción de nuevos templos, en el que jugó un papel muy destacado Cubillo, convertido en arquitecto de confianza de la Oficina Técnica del Arzobispado-------------------------ABSTRACT------------------------------ This Doctoral Thesis fills the emptiness of knowledge about the religious architecture of Luis Cubillo de Arteaga, architect mainly known for his contribution to Madrid's social housing in the 50s and 60s, but with a wide sacred work. To this end it have been studied his entire production, ranging from 1954 to 1974. The thesis discusses his religious architecture from several points of view, including the implementation of the buildings and their formal, constructive and typological aspects, the latter especially important by following the guidelines issued by Vatican II. Previously, four relevant areas in Cubillo’s religious architecture are analyzed. First of all, it’s studied the work of the Department of Ecclesiastical Affairs, to which the architect was assigned and for whom he made his early works. As a part of it, is exposed the evolution of Seminar model between 40s and 60s, to discuss the relevance of Cubillo’s design for the Seminar of Castellón. Next, it´s studied the participation of Cubillo in the construction of the outskirts of Madrid, although not referring to his well known work on social housing, but to the design of the comunitary buildings. It’s also explained an unpublished initiative from Commissariat for Urban Planning of Madrid to provide parish centers to new neighborhoods. A third section examines a recurring theme in the late 50s, the integration of the arts in the new religious architecture, mainly leaded by José Luis Fernández del Amo. For Cubillo, the most notable collaborations, studied in this thesis, were with the artists Arcadio Blasco and José Luis Sánchez. Finally, it´s described the situation of the post-conciliar church in Madrid and its plan to build new temples, with a prominent role of Cubillo, that became in trusted architect of the Technical Office of the Archbishop.
