Effectiveness of improved cookstoves to reduce indoor air pollution in developing countries. The case of the Cassamance Natural Subregion, Western Africa

The Spanish NGO "Alianza por la Solidaridad" has installed improved cookstoves in 3000 households during 2012 and 2013 to improve energy efficiency reducing fuelwood consumption and to improve indoor air quality. The type of cookstoves were Noflaye Jeeg and Noflaye Jaboot and were installed in the Cassamance Natural Subregion covering part of Senegal, The Gambia and Guinea-Bissau. The Technical University of Madrid (UPM) has conducted a field study on a sample of these households to assess the effect of improved cookstoves on kitchen air quality. Measurements of carbon monoxide (CO) and fine particle matter (PM2.5) were taken for 24-hr period before and after the installation of improved cookstoves. The 24-hr mean CO concentrations were lower than the World Health Organization (WHO) guidelines for Guinea-Bissau but higher for Senegal and Gambia, even after the installation of improved cookstoves. As for PM2.5 concentrations, 24-hr mean were always higher than these guidelines. However, improved cookstoves produced significant reductions on 24-hr mean CO and PM2.5 concentrations in Senegal and for mean and maximum PM2.5 concentration on Gambia. Although this variability needs to be explained by further research to determine which other factors could affect indoor air pollution, the study provided a better understanding of the problem and envisaged alternatives to be implemented in future phases of the NGO project.

Can Lis : la huella de la arquitectura de Jørn Utzon a través de esta obra

La tesis “CAN LIS, La huella de la arquitectura de Jørn Utzon a través de su obra Can Lis” analiza en profundidad la vivienda que Jørn Utzon realizó para sí mismo en la entonces calle de la Media Luna, Porto Petro, Mallorca, entre los años 1970-74. La investigación plantea el análisis de esta obra maestra de la arquitectura, sus causas e intenciones, su proceso proyectual, su proceso constructivo, sus relaciones e influencias y sus significados últimos. Este estudio es fruto de una labor de investigación que comenzó hace más de 10 años. Enfrentarse a una obra cuya imagen es tan conocida es una tarea menos sencilla de lo que pudiera parecer. La descripción del proceso de trabajo de Jørn Utzon en Can Lis, y de su método en general, contiene un considerable número de mitificaciones que han sido comúnmente sostenidas por diversos estudiosos de prestigio, que han abordado esta obra sin un estudio razonable de la documentación existente, ni una investigación de los archivos, ni una comprobación de los hechos o una consulta de los testigos intervinientes. Por ello, cuestiones fundamentales habían quedado en el terreno de la conjetura y permanecía deformada la visión general de los procesos de Jørn Utzon en Mallorca. La tesis se ha estructurado en dos grandes apartados que permitan la comprensión de los elementos fundamentales para su gestación: por un lado, el proceso proyectual y constructivo con sus circunstancias y condicionantes y, por otro, el conjunto de hechos y conceptos que han influido de manera directa y significativa en su concreción. Esta investigación contiene una cantidad considerable de materiales y hechos inéditos, fruto de su desarrollo, así como documentación y dibujos nunca publicados anteriormente. Es por tanto, el estudio más completo realizado sobre Can Lis hasta la fecha. En la primera parte de la tesis “CAN LIS” se aborda todo el proceso proyectual de Can Lis desde los primeros croquis, con las condiciones y motivaciones iniciales, los proyectos sucesivos, el proyecto básico y el proyecto de ejecución, hasta el proceso de construcción, su desarrollo y circunstancias, así como las modificaciones posteriores introducidas. Estos elementos se estructuran en tres apartados 1) Las condiciones y condicionantes iniciales. 2) El proceso proyectual. 3) El proceso constructivo. En la segunda parte de la tesis “La huella de la arquitectura de Jørn Utzon a través de su obra Can Lis” se han analizado de manera particular algunos hechos arquitectónicos y vitales previos que fueron especialmente determinantes en la concepción de Can Lis y la serie de influencias directas que son imprescindibles para la comprensión de las condiciones en que se desarrolló y de las ideas que alumbra. Estudios previos de toda la trayectoria de Utzon y todo el corpus de influencias ayudaron a determinar cuáles de ellos son fundamentales para la comprensión del proceso. Estos elementos se pueden considerar directamente precursores de ideas desarrolladas específicamente en Can Lis: 4) La experimentación en Australia: la naturaleza, la dimensión humana y la técnica. La casa de Bayview. 5) Utzon y el descubrimiento de lo islámico: la secuencia espacial, la materia y la luz de la arquitectura islámica como experiencia de aprendizaje. 6) Paisaje sacro, hombre y arquitectura: la búsqueda de Utzon en Grecia. Las conclusiones de este estudio determinan una serie de certezas sobre los procesos de Jørn Utzon en Can Lis, y en su obra global, durante las diversas fases creativas que desmitifican muchos acercamientos precedentes: la visión universal de la arquitectura en su acercamiento al proyecto, el entretejido método proyectual de Utzon, la precisa búsqueda del desarrollo constructivo junto a la ejemplaridad en el rigor, la vitalidad y la espiritualidad con que Utzon aborda la arquitectura, la trascendencia de la forma de habitar de las personas y el valor que para Utzon tiene la arquitectura como medio para revelar el orden universal que nos rodea. ABSTRACT “CAN LIS. The footprint of Jørn Utzon´s architecture through his work Can Lis” carries out a thorough analysis of the house Jørn built for himself between 1970 and 1974 on the street formerly called Calle de la Media Luna, in Porto Petro on the island of Mallorca. The research focuses on the causes that brought about this masterpiece, its purposes, design and building processes, its relations with and influences on other buildings and its ultimate meanings. This study is the result of a research that started over 10 years ago. Approaching a piece of work whose image is so well-known is harder than one might think. Many aspects of Jørn Utzon´s working method in Can Lis particularly but also generally have been described inaccurately and mythicized by several renowned scholars, who hadn´t really studied the existing documents or archives nor confirmed their hypotheses or consulted witnesses of the creation of Can Lis. This is why many key issues have been uncertain all this time and the general idea about Utzon´s working process in Mallorca has been distorted. This dissertation has been structured into two main sections with the aim of helping understand all the facts that led to the creation of the building: the first part describes the design and building processes, as well as the circumstances and constraints under which they were carried out. The second part presents the events and ideas that directly and indirectly influenced the final work. This thesis contains a large amount of unpublished material and information, documents and drawings from the creation process as the inevitable result of a long lasting tenacious research. It probably is the most comprehensive study on Can Lis so far. The first section, “CAN LIS”, addresses the design process of Can Lis from the very first sketches all the way through the subsequent plans, including basic and execution plans and the building process up to the changes that were later carried out on the building. The project´s initial conditions and Utzon´s first motivations and the evolution and circumstances of the building process are also described in this section, which has been divided into three parts: 1. The initial conditions and constraints. 2. The design process. 3. The building process. The second section, “The footprint of Jørn Utzon´s architecture through his work Can Lis”, focuses on some events in Utzon´s life and some of his architectural experiences prior to the creation of Can Lis that were decisive to it. Also the direct influences on the process which are key to understanding the conditions under which the creation was carried out as well as the ideas Can Lis sheds a light on are illustrated in this section. A thorough study of the whole process Utzon went through and of all the influences he was subjected to helped determine what is crucial to comprehending Can Lis. These events or experiences can be considered as the direct precursors to the ideas that crystallised in this master piece: 4. Experiments carried out in Australia: nature, human and technical dimensions. The Bayview house. 5. Utzon´s discovery of Islamic architecture: spatial sequences, matter and light as a learning experience. 6. Sacred landscape, man and architecture: Utzon´s quest in Greece. The findings of this research determine some aspects of Utzon´s working methods at every stage of the creation process both in Can Lis and in general, thus shedding light on previous mistaken ideas about Utzon´s way of working. A universal understanding of architecture, an intertwined design method, a tenacious search for the exact construction solutions, an exemplary rigour, vitality and spirituality in the design approach, the transcendence of our way of living and architecture´s potential to reveal the Universal order that surrounds are all aspects that do define Utzon as an architect.

Discourses and values underpin public debate on fracking in Spain: a case study at the crossroad

In the EU context extraction of shale and oil gas by hydraulic fracturing (fracking) differs from country to country in terms of legislation and implementation. While fossil fuel extraction using this technology is currently taking place in the UK, Germany and France have adopted respective moratoria. In between is the Spanish case, where hydrocarbon extraction projects through fracking have to undergo mandatory and routine environmental assessment in accordance with the last changes to environmental regulations. Nowadays Spain is at the crossroad with respect to the future of this technology. We presume a social conflictt in our country since the position and strategy of the involved and confronted social actors -national, regional and local authorities, energy companies, scientists, NGO and other social organization- are going to play key and likely divergent roles in its industrial implementation and public acceptance. In order to improve knowledge on how to address these controverted situations from the own engineering context, the affiliated units from the Higher Technical School of Mines and Energy Engineering at UPM have been working on a transversal program to teach values and ethics. Over the past seven years, this pioneering experience has shown the usefulness of applying a consequentialist ethics, based on a case-by-case approach and costs-benefits analysis both for action and inaction. As a result of this initiative a theoretical concept has arisen and crystallized in this field: it is named Inter-ethics. This theoretical perspective can be very helpful in complex situations, with multi-stakeholders and plurality of interests, when ethical management requires the interaction between the respective ethics of each group; professional ethics of a single group is not enough. Under this inter-ethics theoretical framework and applying content analysis techniques, this paper explores the articulation of the discourse in favour and against fracking technology and its underlying values as manifested in the Spanish traditional mass media and emerging social media such as Youtube. Results show that Spanish public discourse on fracking technology includes the costs-benefits analysis to communicate how natural resources from local communities may be affected by these facilities due to environmental, health and economic consequences. Furthermore, this technology is represented as a solution to the "demand of energy" according to the optimistic discourse while, from a pessimistic view, fracking is often framed as a source "environmental problems" and even natural disasters as possible earthquakes. In this latter case, this negative representation could have been influenced by the closure of a macro project to store injected natural gas in the Mediterranean Sea using the old facilities of an oil exploitation in Amposta (Proyecto Cástor). The closure of this project was due to the occurrence of earthquakes whose intensity was higher than the originally expected by the experts in the assessment stage of the project.

ASSISTÊNCIA DE SAÚDE ÀS MULHERES MUÇULMANAS NO BRASIL: UMA ANÁLISE DA RELAÇÃO ENTRE O SISTEMA RELIGIOSO ISLÂMICO E A POLÍTICA NACIONAL DE ATENÇÃO INTEGRAL À SAÚDE DA MULHER.

A presente dissertação tem por objetivo analisar os aspectos religiosos islâmicos e as implicações das relações de gênero no islam sobre a assistência de saúde às mulheres muçulmanas, e através disto, discutir a importância do conhecimento prévio do islamismo pelos profissionais de saúde para propor uma assistência de saúde congruente a estas mulheres, tendo por referência a Política Nacional de Atenção Integral à Saúde da Mulher. Esta pesquisa tem abordagem qualitativa, com o desenvolvimento de pesquisa de campo e aplicação de um roteiro de perguntas semi-estruturado, com questões relacionadas ao islamismo e à saúde das mulheres. Ao todo, foram entrevistadas dez pessoas, sendo estas: quatro mulheres revertidas ao islam, três mulheres de família muçulmana, dois sheiks e uma assistente social. As entrevistas foram realizadas no Centro de Divulgação do Islam para a América Latina e o Caribe (CDIAL) e na Assembléia Mundial da Juventude Islâmica na América Latina (WAMY).

Second generation hybrid polar compounds are potent inducers of transformed cell differentiation.

Hybrid polar compounds, of which hexamethylenebisacetamide (HMBA) is the prototype, are potent inducers of differentiation of murine erythroleukemia (MEL) cells and a wide variety of other transformed cells. HMBA has been shown to induce differentiation of neoplastic cells in patients, but is not an adequate therapeutic agent because of dose-limiting toxicity. We report on a group of three potent second generation hybrid polar compounds, diethyl bis-(pentamethylene-N,N-dimethylcarboxamide) malonate (EMBA), suberoylanilide hydroxamic acid (SAHA), and m-carboxycinnamic acid bis-hydroxamide (CBHA) with optimal concentrations for inducing MEL cells of 0.4 mM, 2 microM, and 4 microM, respectively, compared to 5 mM for HMBA. All three agents induce accumulation of underphosphorylated pRB; increased levels of p2l protein, a prolongation of the initial G1 phase of the cell cycle; and accumulation of hemoglobin. However, based upon their effective concentrations, the cross-resistance or sensitivity of an HMBA-resistant MEL cell variant, and differences in c-myb expression during induction, these differentiation-inducing hybrid polar compounds can be grouped into two subsets, HMBA/EMBA and SAHA/CBHA. This classification may prove of value in selecting and planning prospective preclinical and clinical studies toward the treatment of cancer by differentiation therapy.

Gain of function mutations for paralogous Hox genes: implications for the evolution of Hox gene function.

To investigate the functions of paralogous Hox genes, we compared the phenotypic consequences of altering the embryonic patterns of expression of Hoxb-8 and Hoxc-8 in transgenic mice. A comparison of the phenotypic consequences of altered expression of the two paralogs in the axial skeletons of newborns revealed an array of common transformations as well as morphological changes unique to each gene. Divergence of function of the two paralogs was clearly evident in costal derivatives, where increased expression of the two genes affected opposite ends of the ribs. Many of the morphological consequences of expanding the mesodermal domain and magnitude of expression of either gene were atavistic, inducing the transformation of axial skeletal structures from a modern to an earlier evolutionary form. We propose that regional specialization of the vertebral column has been driven by regionalization of Hox gene function and that a major aspect of this evolutionary progression may have been restriction of Hox gene expression.

Uzbekistán: la configuración de un nuevo estado. Especial referencia al estatus de la mujer

Uzbekistan has a long and interesting heritage of ancient civilization linked to the historic “Silk Road”, through which transited people, goods, ideas and cultures. The major cities of the Silk Road - Samarkand, Bukhara, and Khiva are testimonies of the past and leave a deep impression on any visitor. As time goes by, Uzbekistan has become a key country in the whole Central Asian region, because it possesses mineral, agricultural and natural resources and has a huge potential for development. It is rich in energy resources such as oil and gas, but it is very difficult to commercialize them due to its landlocked position. The historical legacy of the Republic of Uzbekistan is a valuable heritage. The above mentioned ancient cities used to be centers of science and art, where important architects created palaces, mosques, madrassas, minarets, and mausoleums of the Islamic style, that still exist today. This cultural wealth is an element of internal cohesion and external outreach towards Islamic heritage, related to such Muslim countries as Turkey and the Gulf States. Moreover, this historical and architectural heritage has enormous economic potential for tourism, which can contribute to strengthen the relations of cooperation and friendship between Uzbekistan and the International Society. The influence of tradition and culture has still a huge impact on the society. This can be felt for example, in the traditional gender roles distribution. As a result of which, meńs presence in the areas of decision making is still slightly higher than womeńs one...

New Middle East Cold War: Saudi Arabia and Iran's Rivalry

The competing powers of Saudi Arabia and Iran continue to redress and reverse the strategic imbalance and direction of the Middle East’s regional politics. The 1979 Iranian Revolution catapulted these two states into an embittered rivalry. The fall of Saddam Hussein following the 2003 U.S. led invasion, the establishment of a Shi’ite Iraq and the 2011 Arab Uprisings have further inflamed tensions between Saudi Arabia and Iran. Iran and Saudi Arabia have not confronted each other militarily, but rather have divided the region into two armed camps on the basis of political and religious ideology in seeking regional allies and promulgating sectarianism as they continue to exploit the region’s weak states in a series of proxy wars ranging from conflicts in Iraq to Lebanon. The Saudi-Iranian strategic and geopolitical rivalry is further complicated by a religious and ideological rivalry, as tensions represent two opposing aspirations for Islamic leadership with two vastly differing political systems. The conflict is between Saudi Arabia, representing Sunni Islam via Wahhabism, and Iran, representing Shi’ite Islam through Khomeinism. The nature of the Saudi-Iranian rivalry has led many Middle East experts to identify their rivalry as a “New Middle East Cold War.” The Saudi-Iranian rivalry has important implications for regional stability and U.S. national security interests. Therefore, this thesis seeks to address the question: Is a cold war framework applicable when analyzing the Saudi Arabian and Iranian relationship?

Secularism, Sharia, and the Turkish Financial Markets

The financial markets in Turkey provide a laboratory to help resolve these competing views. Islamic law or Sharia contains a number of proscriptions that directly affect financial practices. The payment and receipt of interest is prohibited; so are most kinds of commercial insurance. These interpretations provided the impetus in the Islamic world for the creation of a class of banks that sought to offer Sharia compliant services. The first Islamic Banks in Turkey began operations in the 1980s. Their entry was initially tepid, in no small part because of secularist principles. Islamic financial institutions could not overtly advertise their religious orientation. The country had no “Islamic” banks, only finance houses. They were not Sharia compliant but “interest-free.” Moreover, the government left them in an uncertain regulatory status and subjected them to restrictions on growth. In this environment, the Islamic banks remained a peripheral part of the financial system. With the election of the AKP in 2002, however, the environment for Islamic banks in Turkey changed. Limitations on branch networks and capital raising were lifted. The government removed restrictions on the issuance of Sharia compliant bonds. Officials from the Islamic banks were appointed to the highest levels of government. This Article does several things. First, it examines principles of Islam that affect banking practices, with a particular emphasis on deposit insurance and credit cards. Second, the Article discusses the emergence of secularism in Turkey and the introduction of Islamic banks into the Turkish financial markets. The Article then examine their evolution, with particular emphasis on the changes implemented by the AKP. Finally, the Article examines the impact of these reforms, and what that impact says about Islamic influence in Turkey.

The assignment of credit through bills of exchange and transmission documents in Andalusi Law

The exchange traffic was a practice that suited the modus vivendi of caravanners and traders in the Islamic world. The inclusion of the Iberian.Peninsula into the most important commercial routes of Muslims – such as the silk route through the North Africa – provides a very solid reason to deepen in the study of the sources that have been preserved about the role that certain credit instruments, which represented an alternative to the coin, might have played in trade centres.

Gramática de la casa: perspectivas de análisis arqueológico de los espacios domésticos medievales en la Península Ibérica (siglos VII-XIII)

El espacio doméstico construido es un producto social que a su vez crea sociedad. La casa constituye un escenario privilegiado, un medio de expresión y transmisión de conductas y comportamientos. No obstante, resulta muy difícil comprender el espacio social a través de unas ruinas arqueológicas vacías y carentes de tercera dimensión, y se corre el riesgo de proyectar una imagen historiográfica previamente construida sobre las sociedades estudiadas. La comprensión del espacio social requiere formalizar y discutir los patrones formales de las estructuras domésticas y sus formas de agrupación. Este trabajo aborda el estudio de los espacios domésticos desde una perspectiva lingüística (una gramática de la casa), distinguiendo los elementos en sí y sus combinaciones. Se definen tres niveles distintos de análisis del hecho doméstico: el morfológico, que se ocupa de la forma de las unidades domésticas y de las transformaciones que experimentan; el sintáctico que enfatiza las relaciones entre las estructuras elementales en el marco de una estructura espacial organizada; y el semiótico, que las analiza como expresiones sociales, materialización e instrumento de significados culturales. De acuerdo a esta perspectiva se propone una reflexión metodológica sobre la caracterización de los espacios domésticos medievales e islámicos en la Península Ibérica; se plantean los problemas derivados del uso social del espacio, los modelos domésticos y su diacronía, y se discute acerca de la casa como indicador material de islamización.

Bibliografía sobre temas árabes de las Baleares

Se recogen 730 referencias bibliográficas que tratan de las Baleares durante el periodo andalusí, de la conquista cristiana y sus diferentes documentos (Repartiment, etc.), del período de dominio cristiano en el cual los musulmanes, primero –como mudéjares– eran un grupo social mayoritario, y luego –como meros esclavos, pasaron a ser minoría en la Edad Moderna, en la que además de este fenómeno de los esclavos musulmanes nos hemos fijado en el de la piratería islámica proveniente del norte de África. En las épocas sucesivas hemos creído conveniente recoger los trabajos que hagan referencia a las Baleares y sus relaciones de diversa índole con el mundo islámico. Además de otros muchos estudios de índole cultural, social, económica, arqueológica, política, etc., que se encuadren u ocupen de estos períodos cronológicos. Igualmente se han recogido los trabajos más generales en los que se halle referencia a las islas, bien de geógrafos árabes (descripciones geográficas), o literatos, científicos y demás personajes musulmanes, de tratados islámicos medievales, o de fuentes cristianas que las mencionen y nos muestren la huella o legado de lo árabe.

Tesorillo islámico de la calle Jabonerías de Murcia

Presentamos un conjunto de 424 monedas y 4 objetos de oro recuperados durante la excavación de una vivienda islámica en la calle Jabonerías de Murcia construida en el siglo XI. Las monedas se hallaban en el interior de una vasija cerámica que se ocultaba en uno de los muros de dicha casa. El tesorillo está compuesto por moneda procedente del norte de África y Sicilia, mayoritariamente fatimí, y fracciones de dinar de las taifas andalusíes.

The episcopal complex of Eio-El Tolmo de Minateda (Hellín, Albacete, Spain). Architecture and spatial organization. 7th to 8th centuries AD

The episcopal complex of Eio, located in El Tolmo de Minateda, was built between the end of the 6th century and the beginning of the 7th century, possibly as a political decision taken by the ecclesiastical authority in the capital of the Visigothic kingdom (Toletum). With the comprehensive study of the whole complex presented below (construction cycles, furniture, decoration and location of spaces), we can interpret the function of each space in the basilica and the domus episcopi, the liturgical and general movement routes, the existence of some hierarchical environments, and specify the chronological development of the buildings. After the Arab-Berber conquest of Hispania in the early 8th century, the whole complex will experience a series of transformations that will convert the religious and monumental public area into a private, residential and industrial Islamic quarter.
