Nutritive value of palm kernel meal in diets for growing rabbits

The aim of this work was to determine the nutritive value of palm kernel meal (PKM) in diets for growing rabbits. In Experiment 1, 20 New Zealand × Californian growing rabbits 50 d-old were used to determine energy, crude protein, fibre and fat digestibility of PKM. The nutritive value was estimated by the difference method using a basal diet and another diet made by substituting 200 g/kg of basal diet with PKM. Energy, crude protein, ether extract and neutral detergent fibre of PKM digestibilities were, respectively, 0.549 (±0.056, SE), 0.541 (±0.069), 0.850 (±0.048) and 0.430 (±0.101), and the digestible energy concentration was 10.9 MJ/kg (±1.03) DM. In Experiment 2, 412 rabbits were allocated at random to the two experimental diets to measure growing performance. Inclusion of 200 g PKM/kg in the diet did not affect feed or digestible energy intake but decreased slightly (by around 5%) average daily gain (P = 0.003) and feed efficiency (P < 0.001). Neither mortality nor Clostridium perfringens counts in soft faeces were affected by type of diet. Palm kernel meal can be considered a palatable source of fibre, protein and fat for rabbits and can substitute significant amounts of other fibrous ingredients in the diet without adverse effects on growth performance.

Determination of pH dependent antioxidant activity of Palm (Borassus flabellifer) Polyphenol compounds by Photoluminol and DPPH methods -A Comparison redox-reaction Sensitivity

Palm juice (Borassus flabellifer) is one of the most common and cheap natural juices. Fermented palm juice contains various phytochemical compounds that exhibit antioxidant activity. In the present study, we examined the effects of pH on the production of phytochemicals and their antioxidant activity during the fermentation process. The concentration of total phenolics and flavonoid compounds of fermented palm juice and their antioxidant activity were investigated at various pH. The results showed that total phenolics concentration and antioxidant activity of palm wine and palm vinegar increase as pH increases: 3.54.55.5. Maximum flavonoid concentration was obtained at pH 6.5. Measurements of antioxidant activity by conventional DPPH method and Photochem antioxidant analyzer technique were highly correlated, with a corresponding R2 value of 0.94.

Effects of nutrition on digestión efficiency and gaseous emissions from slurry in growing pigs: III. Influence of varying the dietary level of calcium soap of palm fatty acids distillate with or without orange pulp supplemention

The aim of this study was to establish the relationships between faecal fat concentration and gaseous emissions from pig slurry. Five diets were designed to meet essential nutrient requirements: a control and four experimental feeds including two levels (35 or 70 g/kg) of calcium soap fatty acids distillate (CSP) and 0 or 200 g/kg of orange pulp (OP) combined in a 2 × 2 factorial structure. Thirty growing pigs (six per treatment) were used to measure dry matter (DM) and N balance, coefficients of total tract apparent digestibility (CTTAD) of nutrients, faecal and urine composition and potential emissions of ammonia (NH3) and methane (CH4). Increasing dietary CSP level decreased DM, ether extract (EE) and crude protein (CP) CTTAD (by 4.0, 11.1 and 3.5%, respectively, P < 0.05), but did not influence those of fibrous constituents. It also led to a decrease (from 475 to 412 g/kg DM, P < 0.001) of faecal concentration of neutral detergent fibre (aNDFom) and to an increment (from 138 to 204 g/kg, P < 0.001) of EE in faecal DM that was related to greater CH4 emissions, both per gram of organic matter (P = 0.021) or on a daily basis (P < 0.001). Level of CSP did not affect N content in faeces or urine, but increased daily DM (P < 0.001), and N (P = 0.031) faecal excretion with no effect on urine N excretion. This resulted in lesser (P = 0.036) NH3 potential emission per kg of slurry. Addition of OP decreased CTTAD of EE (by 7.9%, P = 0.044), but increased (P < 0.05) that of all the fibrous fractions. As a consequence, faecal EE content increased (from 165 to 177 g/kg DM; P = 0.012), and aNDFom decreased greatly (from 483 to 404 g/kg DM, P < 0.001), which in all resulted in a lack of effect of OP on CH4 potential emission. Inclusion of OP in the diet also led to a significant decrease of CP CTTAD (by 6.85%, P < 0.001), and to an increase of faecal CP concentration (from 174 to 226 g/kg DM, P < 0.001), with no significant influence on urine N content. These effects resulted in higher N faecal losses, especially those of the undigested dietary origin, without significant effects on potential NH3 emission. No significant interactions between CSP and OP supplementation were observed for the gaseous emissions measured.

Oasis. La casa Loewy en el desierto de Palm Spring = Oasis. Loewy House in the Desert of Palm Spring

En los tiempos de la optimista eclosión del Estilo Internacional en América y del comienzo de una nueva domesticidad en California, la peculiar mirada que hiciera el fotógrafo Julius Shulman de la casa Loewy, construida por Albert Frey en el desierto de Palm Springs en 1947, nos permite reconocer las claves de una excepcional pieza de arquitectura. La simbiótica aportación que hiciera Loewy junto a Frey permite superar ampliamente los rigurosos estándares de lo moderno y consigue exaltar el hedonismo de la cultura del bienestar de la posguerra americana. Atmósfera e intención se unen en una fantástica creación tanto de un espacio como de un tiempo.

Influencia del ejercicio físico desarrollado durante el embarazo en la respuesta cardiaca fetal = Influence of a physical activity program performed during pregnancy on fetal heart response

INTRODUCCIÓN: El riesgo de padecer enfermedades cardiovasculares y los índices de obesidad infantil han ido en aumento durante los últimos años empobreciendo la salud de la población. La Teoría de Barker relaciona el estado de salud de la madre con el desarrollo fetal, asociando a un deficiente estado físico y hábitos de vida negativos de la mujer embarazada con el aumento del riesgo de padecer cardiopatías en la infancia y adolescencia, así como predisponer al recién nacido a padecer sobrepeso y/u obesidad en su vida posterior. Por otro lado los estudios efectuados sobre ejercicio físico durante el embarazo reportan beneficios para salud materna y fetal. Uno de los parámetros más utilizados para comprobar la salud fetal es su frecuencia cardiaca, mediante la que se comprueba el buen desarrollo del sistema nervioso autónomo. Si se observa este parámetro en presencia de ejercicio materno podría encontrarse una respuesta crónica del corazón fetal al ejercicio materno como consecuencia de una adaptación y mejora en el funcionamiento del sistema nervioso autónomo del feto. De esta forma podría mejorar su salud cardiovascular intrauterina, lo que podría mantenerse en su vida posterior descendiendo el riesgo de padecer enfermedades cardiovasculares en la edad adulta. OBJETIVOS: Conocer la influencia de un programa de ejercicio físico supervisado en la frecuencia cardiaca fetal (FCF) en reposo y después del ejercicio materno en relación con gestantes sedentarias mediante la realización de un protocolo específico. Conocer la influencia de un programa de ejercicio físico en el desarrollo del sistema nervioso autónomo fetal, relacionado con el tiempo de recuperación de la FCF. MATERIAL Y MÉTODO: Se diseñó un ensayo clínico aleatorizado multicéntrico en el que participaron 81 gestantes (GC=38, GE=43). El estudio fue aprobado por el comité ético de los hospitales que participaron en el estudio. Todas las gestantes fueron informadas y firmaron un consentimiento para su participación en el estudio. Las participantes del GE recibieron una intervención basada en un programa de ejercicio físico desarrollado durante la gestación (12-36 semanas de gestación) con una frecuencia de tres veces por semana. Todas las gestantes realizaron un protocolo de medida de la FCF entre las semanas 34-36 de gestación. Dicho protocolo consistía en dos test llevados a cabo caminando a diferentes intensidades (40% y 60% de la frecuencia cardiaca de reserva). De este protocolo se obtuvieron las principales variables de estudio: FCF en reposo, FCF posejercicio al 40 y al 60% de intensidad, tiempo de recuperación de la frecuencia cardiaca fetal en ambos esfuerzos. El material utilizado para la realización del protocolo fue un monitor de frecuencia cardiaca para controlar la frecuencia cardiaca de la gestante y un monitor fetal inalámbrico (telemetría fetal) para registrar el latido fetal durante todo el protocolo. RESULTADOS: No se encontraron diferencias estadísticamente significativas en la FCF en reposo entre grupos (GE=140,88 lat/min vs GC= 141,95 lat/min; p>,05). Se encontraron diferencias estadísticamente significativas en el tiempo de recuperación de la FCF entre los fetos de ambos grupos (GE=135,65 s vs GC=426,11 s esfuerzo al 40%; p<,001); (GE=180,26 s vs GC=565,61 s esfuerzo al 60%; p<,001). Se encontraron diferencias estadísticamente significativas en la FCF posejercicio al 40% (GE=139,93 lat/min vs GC=147,87 lat/min; p<,01). No se encontraron diferencias estadísticamente significativas en la FCF posejercicio al 60% (GE=143,74 lat/min vs GC=148,08 lat/min; p>,05). CONLUSIÓN: El programa de ejercicio físico desarrollado durante la gestación influyó sobre el corazón fetal de los fetos de las gestantes del GE en relación con el tiempo de recuperación de la FCF. Los resultados muestran un posible mejor funcionamiento del sistema nervioso autónomo en fetos de gestantes activas durante el embarazo. ABSTRACT INTRODUCTION: The risk to suffer cardiovascular diseases and childhood obesity index has grown in the last years worsening the health around the population. Barker´s Theory related maternal health with fetal development establishing an association between a poorly physical state and an unhealthy lifestyle in the pregnant woman with the risk to suffer heart disease during childhood and adolescence, childhood overweight and/or obese is related to maternal lifestyle. By the other way researches carried out about physical exercise and pregnancy show benefits in maternal and fetal health. One of the most studied parameters to check fetal health is its heart rate, correct fetal autonomic nervous system development and work is also corroborated by fetal heart rate. Looking at this parameter during maternal exercise a chronic response of fetal heart could be found due to an adaptation and improvement in the working of the autonomic nervous system. Therefore its cardiovascular health could be enhanced during its intrauterine life and maybe it could be maintained in its posterior life descending the risk to suffer cardiovascular diseases in adult life. OBJECTIVES: To know the influence of a supervised physical activity program in the fetal heart rate (FHR) at rest, FHR after maternal exercise related to sedentary pregnant women by a FHR assessment protocol. To know the influence of a physical activity program in the development of the autonomic nervous system related to FHR recovery time. MATERIAL AND METHOD: A multicentric randomized clinical trial was design in which 81 pregnant women participated (CG=38, EG=43). The study was approved by the ethics committee of all of the hospitals participating in the study. All of the participants signed an informed consent for their participation in the study. EG participants received an intervention based on a physical activity program carried out during gestation (12-36 gestation weeks) with a three days a week frequency. All of the participants were tested between 34-36 weeks of gestation by a specific FHR assessment protocol. The mentioned protocol consisted in two test performed walking and at a two different intensities (40% and 60% of the reserve heart rate). From this protocol we obtained the main research variables: FHR at rest, FHR post-exercise at 40% and 60% intensity, and FHR recovery time at both walking test. The material used to perform the protocol were a FH monitor to check maternal HR and a wireless fetal monitor (Telemetry) to register fetal beats during the whole protocol. RESULTS: There were no statistical differences in FHR at rest between groups (EG=140,88 beats/min vs CG= 141,95 beats/min; p>,05). There were statistical differences in FHR recovery time in both walking tests between groups (EG=135,65 s vs CG=426,11 s test at 40% intensity; p<,001); (EG=180,26 s vs CG=565,61 s test at 60% intensity; p<,001). Statistical differences were found in FHR post-exercise at 40% intensity between groups (EG=139,93 beats/min vs CG=147,87 beats/min; p<,01). No statistical differences were found in FHR at rest post-exercise at 60% intensity between groups (EG=143,74 beats/min vs CG=148,08 beats/min; p>,05). CONCLUSIONS: The physical activity program performed during gestation had an influence in fetal heart of the fetus from mother in the EG related to FHR recovery time. These results show a possible enhancement on autonomic nervous system working in fetus from active mothers during gestation.

Assessment of Hydrogen as suistinable clean energy

The progressive depletion of fossil fuels and their high contribution to the energy supply in this modern society forces that will be soon replaced by renewable fuels. But the dispersion and alternation of renewable energy production also undertake to reduce their costs to use as energy storage and hydrogen carrier. It is necessary to develop technologies for hydrogen production from all renewable energy storage technologies and the development of energy production from hydrogen fuel cells and cogeneration and tri generation systems. In order to propel this technological development discussed where the hydrogen plays a key role as energy storage and renewable energy, the National Centre of Hydrogen and Fuel Cell Technology Experimentation in Spain equipped with installations that enable scientific and technological design, develop, verify, certify, approve, test, measure and, more importantly, the facility ensures continuous operation for 24 hours a day, 365 days year. At the same time, the system is scalable so as to allow continuous adaptation of new technologies are developed and incorporated into the assembly to verify integration at the same time it checks the validity of their development. The transformation sector can be said to be the heart of the system, because without neglecting the other sectors, this should prove the validity of hydrogen as a carrier - energy storage are important efforts that have to do to demonstrate the suitability of fuel cells or internal combustion systems to realize the energy stored in hydrogen at prices competitive with conventional systems. The multiple roles to meet the fuel cells under different conditions of operation require to cover their operating conditions, many different sizes and applications. The fourth area focuses on integration is an essential complement within the installation. We must integrate not only the electricity produced, but also hydrogen is used and the heat generated in the process of using hydrogen energy. The energy management in its three forms: hydrogen chemical, electrical and thermal integration requires complicated and require a logic and artificial intelligence extremes to ensure maximum energy efficiency at the same time optimum utilization is achieved. Verification of the development and approval in the entire production system and, ultimately, as a demonstrator set to facilitate the simultaneous evolution of production technology, storage and distribution of hydrogen fuel cells has been assessed.

Pounding force assessment in performance-based design of bridges

Bridges with deck supported on either sliding or elastomeric bearings are very common in mid-seismicity regions. Their main seismic vulnerabilities are related to the pounding of the deck against abutments or between the different deck elements. A simplified model of the longitudinal behavior of those bridges will allow to characterize the reaction forces developed during pounding using the Pacific Earthquake Engineering Research Center framework formula. In order to ensure the general applicability of the results obtained, a large number of system parameter combinations will be considered. The heart of the formula is the identification of suitable intermediate variables. First, the pseudo acceleration spectral value for the fundamental period of the system (Sa(Ts)) will be used as an intensity measure (IM). This IM will result in a very large non-explained variability of the engineering demand parameter. A portion of this variability will be proved to be related to the relative content of high-frequency energy in the input motion. Two vector-valued IMs including a second parameter taking this energy content into account will then be considered. For both of them, a suitable form for the conditional intensity dependence of the response will be obtained. The question of which one to choose will also be analyzed. Finally, additional issues related to the IM will be studied: its applicability to pulse-type records, the validity of scaling records and the sufficiency of the IM.

Integrated assessment of policy interventions for promoting sustainable irrigation in semi-arid environments: A hydro-economic modeling approach

Sustaining irrigated agriculture to meet food production needs while maintaining aquatic ecosystems is at the heart of many policy debates in various parts of the world, especially in arid and semi-arid areas. Researchers and practitioners are increasingly calling for integrated approaches, and policy-makers are progressively supporting the inclusion of ecological and social aspects in water management programs. This paper contributes to this policy debate by providing an integrated economic-hydrologic modeling framework that captures the socio-economic and environmental effects of various policy initiatives and climate variability. This modeling integration includes a risk-based economic optimization model and a hydrologic water management simulation model that have been specified for the Middle Guadiana basin, a vulnerable drought-prone agro-ecological area with highly regulated river systems in southwest Spain. Namely, two key water policy interventions were investigated: the implementation of minimum environmental flows (supported by the European Water Framework Directive, EU WFD), and a reduction in the legal amount of water delivered for irrigation (planned measure included in the new Guadiana River Basin Management Plan, GRBMP, still under discussion). Results indicate that current patterns of excessive water use for irrigation in the basin may put environmental flow demands at risk, jeopardizing the WFD s goal of restoring the ?good ecological status? of water bodies by 2015. Conflicts between environmental and agricultural water uses will be stressed during prolonged dry episodes, and particularly in summer low-flow periods, when there is an important increase of crop irrigation water requirements. Securing minimum stream flows would entail a substantial reduction in irrigation water use for rice cultivation, which might affect the profitability and economic viability of small rice-growing farms located upstream in the river. The new GRBMP could contribute to balance competing water demands in the basin and to increase economic water productivity, but might not be sufficient to ensure the provision of environmental flows as required by the WFD. A thoroughly revision of the basin s water use concession system for irrigation seems to be needed in order to bring the GRBMP in line with the WFD objectives. Furthermore, the study illustrates that social, economic, institutional, and technological factors, in addition to bio-physical conditions, are important issues to be considered for designing and developing water management strategies. The research initiative presented in this paper demonstrates that hydro-economic models can explicitly integrate all these issues, constituting a valuable tool that could assist policy makers for implementing sustainable irrigation policies.

Abstract specialization and its applications

The aim of program specialization is to optimize programs by exploiting certain knowledge about the context in which the program will execute. There exist many program manipulation techniques which allow specializing the program in different ways. Among them, one of the best known techniques is partial evaluation, often referred to simply as program specialization, which optimizes programs by specializing them for (partially) known input data. In this work we describe abstract specialization, a technique whose main features are: (1) specialization is performed with respect to "abstract" valúes rather than "concrete" ones, and (2) abstract interpretation rather than standard interpretation of the program is used in order to propágate information about execution states. The concept of abstract specialization is at the heart of the specialization system in CiaoPP, the Ciao system preprocessor. In this paper we present a unifying view of the different specialization techniques used in CiaoPP and discuss their potential applications by means of examples. The applications discussed include program parallelization, optimization of dynamic scheduling (concurreney), and integration of partial evaluation techniques.

Termination and cost analysis: Complexity and precision issues

The research in this thesis is related to static cost and termination analysis. Cost analysis aims at estimating the amount of resources that a given program consumes during the execution, and termination analysis aims at proving that the execution of a given program will eventually terminate. These analyses are strongly related, indeed cost analysis techniques heavily rely on techniques developed for termination analysis. Precision, scalability, and applicability are essential in static analysis in general. Precision is related to the quality of the inferred results, scalability to the size of programs that can be analyzed, and applicability to the class of programs that can be handled by the analysis (independently from precision and scalability issues). This thesis addresses these aspects in the context of cost and termination analysis, from both practical and theoretical perspectives. For cost analysis, we concentrate on the problem of solving cost relations (a form of recurrence relations) into closed-form upper and lower bounds, which is the heart of most modern cost analyzers, and also where most of the precision and applicability limitations can be found. We develop tools, and their underlying theoretical foundations, for solving cost relations that overcome the limitations of existing approaches, and demonstrate superiority in both precision and applicability. A unique feature of our techniques is the ability to smoothly handle both lower and upper bounds, by reversing the corresponding notions in the underlying theory. For termination analysis, we study the hardness of the problem of deciding termination for a speci�c form of simple loops that arise in the context of cost analysis. This study gives a better understanding of the (theoretical) limits of scalability and applicability for both termination and cost analysis.

La iglesia de Santiago de los españoles en Roma y su entorno entre los siglos XV y XIX. Una historia a través del dibujo

Plaza Navona representa una de las visitas obligadas de Roma, pero solo algunos advertirán en ella la presencia española en la sala de exposiciones del Instituto Cervantes o en la inmediata Libreria Española. Todavía serán menos los que se percatarán de la huella española dejada en aquella iglesia de fachada anónima situada, en el extremo sur de la plaza: la antigua iglesia de Santiago de los Españoles. La presente tesis pretende, utilizando el dibujo como guía, herramienta y fin del proceso de análisis y estudio, reconstruir el proceso de conformación y construcción de la que fue iglesia española principal, cuya fundación hace patente el destacado papel jugado por la “nación” castellana en Roma durante la Edad Media; y en torno a la que se aglutinaron las actividades religiosas, diplomáticas y financieras de los castellanos que vivieron en la actual capital italiana. Se intentará recrear en el tiempo la que es hoy la iglesia de Nuestra Señora del Sagrado Corazón, sometiéndola a una restitución gráfica disciplinada, homogénea y objetiva en la medida de lo posible de las varias etapas que la han caracterizadas, desde su fundación hasta cuando en 1878 España se deshizo de ella, ya en ruina, vendiéndola. Como nos comenta Gaetano Moroni, de todas las comunidades nacionales que se encontraban en Roma la española parece ser efectivamente una de las más rica y prestigiosa. Aunque lo que no cuenta Moroni no haya sido todavía demostrado, dicho enunciado resulta de todas formas interesante puesto que pone el acento sobre el hecho de que ya desde el siglo X parece ser habitual de ocupar y reutilizar antiguas ruinas, usándolas como base para la construcción de hospitales para los peregrinos. Esta operación se hizo particularmente frecuente sobre todo antes del Gran Jubileo de 1450: de hecho desde la primera mitad del Quattrocento se fundan distintas iglesias y hospitales nacionales para acoger y prestar una adecuada asistencia y socorro a los innumerables peregrinos que llegaban a la ciudad, edificios que se van construyendo sobre los restos de antiguos edificios de época romana. Prueba de ello es en efecto la fundación originaria de la iglesia y hospital de los Españoles que, parte del conjunto de edificios que compone la Plaza Navona, situada en el corazón de Campo Marzio y cuya posición y forma corresponden a la del antiguo Estadio de Domiciano, y que ahora es en sus dimensiones, en su imagen arquitectónica y en su consistencia material, el resultado de la definición proyectual y de las transformaciones que se llevaron a cabo sobre lo que quedaba del antiguo templo español del siglo XV, entre finales del ‘800 y los años 30 del siglo XX . Transformaciones devastadoras, huellas grabadas o canceladas que encuentran una justificación en los acontecimientos históricos reflejados en el patrimonio urbano. El análisis de todas las fuentes permite trazar, si no la totalidad, buena parte de las modificaciones que la antigua iglesia de Santiago ha sufrido. La construcción del templo se puede dividir en tres momentos decisivos: una primera etapa de fundación en 1450-1478 en la que la iglesia tenía fachada y entrada en via de la Sapienza, hoy Corso Rinascimento; una segunda de significativa ampliación hacia Plaza Navona con una nueva fachada monumental hacia ese espacio público en 1496-1500; y una última importante ampliación entre 1525-1526, llevada a cabo por el arquitecto Antonio da Sangallo el Joven. Tras la intensa vida del templo, en el siglo XVIII, éste cae en ruina y finalmente es vendido en 1878 a la orden de los misioneros franceses de Nuestra Señora del Sagrado Corazón que la reconvierten en iglesia reformando totalmente el conjunto en 1881, según proyecto de Luca Carimini. En 1936, en plena fase de rectificación de trazados urbanos por obra del régimen fascista, según proyecto de Arnaldo Foschini, se mutila su extremidad hacia vía de la Sapienza dejando su estado tal y como se contempla en la actualidad. ABSTRACT The objective of this thesis is the reconstruction of the design and edification process -using drawings and sketches as a guide, tool and the end of the analytical process- of a church which was once the preeminent Spanish church in medieval Rome, known today as Nostra Signora del Sacro Cuore (Our Lady of the Sacred Heart). The founding of this church illustrates the important role held by the Castillian “nation” in Rome during the Middle Ages. It was the focal point of all the religious, diplomatic and economic activities of the Castillian community residing in today’s Italian capital. The aim of this proyect is a recreation the church in time by submitting it to a disciplined, homogenous and objective graphic restitution of the various stages most characteristic the temple, starting from its foundation until 1878 when, in a state of ruins, the church was finally sold off by Spain. Gaetano Moroni once commented that of all the international communities found in Rome, the Spanish community seemed to be one of the wealthiest and most prestigious. Such a statement proves interesting as it emphasizes that starting in the 10th century we see there was a widespread custom of occupying and reusing old ruins for use as the bases of new constructions of hospitals for pilgrims. This custom became especially frequent just before the Jubilee Year of 1450: in fact, in the first half of the Quattrocento we see the founding of many different national churches and hospitals which provided shelter and care to the countless pilgrims arriving in the city, buildings which were constructed on top of the ruins of ancient buildings left over from Roman times. Proof of this is the original foundation of the Spanish church and hospital forming part of the Piazza Navona, built upon and following the outline of the Stadium of Domitian, in the heart of Campo Marzio. Now, in its dimensions, its architectural image and its material substance, it represents the predominant result of the planning definitions and the transformations which affected the old 15th-century Spanish temple. Ocurring between the end of the 19th century and the 1930s, the transformations were devastating, erasing original peculiarities and engraving new ones, transformations made justifiable by the historical events reflected in its urban environs. Analyzing all sources allows us to trace, even if not in entirety, still a sizeable portion of the modifications undergone by the old Church of Saint James. The construction of the temple can be divided into three decisive moments: its foundation, from 1450 to 1478, when the church’s façade and main door looked out on to the Via della Sapienza, today’s central avenue of Corso del Rinascimento; the second stage being a major expansion towards the Piazza Navona (1496-1500) with a new, monumental façade facing the public space; and the third was the last significant expansion, carried out from 1525 to 1526 by the architect Antonio da Sangallo the Younger. Despite an intense and bustling life during the Modern Age, in the 18th century the church began to fall into ruin and was finally sold in 1878 to the order of French missionaries of Our Lady of the Sacred Heart, who reconverted it into a church and completely renovated the structure in 1881 in a project supervised by Luca Carimini. In 1936, the corrective urban redesign of Rome carried out by the fascist regime and implemented by Arnaldo Foschini mutilated the part bordering Via della Sapienza, leaving it as we see it today.

Exploring strategic farming choices to respond to mitigation and adaptation to climate change

Las alteraciones del sistema climático debido al aumento de concentraciones de gases de efecto invernadero (GEI) en la atmósfera, tendrán implicaciones importantes para la agricultura, el medio ambiente y la sociedad. La agricultura es una fuente importante de emisiones de gases de efecto invernadero (globalmente contribuye al 12% del total de GEI), y al mismo tiempo puede ser parte de la solución para mitigar las emisiones y adaptarse al cambio climático. Las acciones frente al desafío del cambio climático deben priorizar estrategias de adaptación y mitigación en la agricultura dentro de la agenda para el desarrollo de políticas. La agricultura es por tanto crucial para la conservación y el uso sostenible de los recursos naturales, que ya están sometidos a impactos del cambio climático, al mismo tiempo que debe suministrar alimentos para una población creciente. Por tanto, es necesaria una coordinación entre las actuales estrategias de política climática y agrícola. El concepto de agricultura climáticamente inteligente ha surgido para integrar todos estos servicios de la producción agraria. Al evaluar opciones para reducir las amenazas del cambio climático para la agricultura y el medio ambiente, surgen dos preguntas de investigación: • ¿Qué información es necesaria para definir prácticas agrarias inteligentes? • ¿Qué factores influyen en la implementación de las prácticas agrarias inteligentes? Esta Tesis trata de proporcionar información relevante sobre estas cuestiones generales con el fin de apoyar el desarrollo de la política climática. Se centra en sistemas agrícolas Mediterráneos. Esta Tesis integra diferentes métodos y herramientas para evaluar las alternativas de gestión agrícola y políticas con potencial para responder a las necesidades de mitigación y adaptación al cambio climático. La investigación incluye enfoques cuantitativos y cualitativos e integra variables agronómicas, de clima y socioeconómicas a escala local y regional. La investigación aporta una recopilación de datos sobre evidencia experimental existente, y un estudio integrado sobre el comportamiento de los agricultores y las posibles alternativas de cambio (por ejemplo, la tecnología, la gestión agrícola y la política climática). Los casos de estudio de esta Tesis - el humedal de Doñana (S España) y la región de Aragón (NE España) - permiten ilustrar dos sistemas Mediterráneos representativos, donde el uso intensivo de la agricultura y las condiciones semiáridas son ya una preocupación. Por este motivo, la adopción de estrategias de mitigación y adaptación puede desempeñar un papel muy importante a la hora de encontrar un equilibrio entre la equidad, la seguridad económica y el medio ambiente en los escenarios de cambio climático. La metodología multidisciplinar de esta tesis incluye una amplia gama de enfoques y métodos para la recopilación y el análisis de datos. La toma de datos se apoya en la revisión bibliográfica de evidencia experimental, bases de datos públicas nacionales e internacionales y datos primarios recopilados mediante entrevistas semi-estructuradas con los grupos de interés (administraciones públicas, responsables políticos, asesores agrícolas, científicos y agricultores) y encuestas con agricultores. Los métodos de análisis incluyen: meta-análisis, modelos de gestión de recursos hídricos (modelo WAAPA), análisis multicriterio para la toma de decisiones, métodos estadísticos (modelos de regresión logística y de Poisson) y herramientas para el desarrollo de políticas basadas en la ciencia. El meta-análisis identifica los umbrales críticos de temperatura que repercuten en el crecimiento y el desarrollo de los tres cultivos principales para la seguridad alimentaria (arroz, maíz y trigo). El modelo WAAPA evalúa el efecto del cambio climático en la gestión del agua para la agricultura de acuerdo a diferentes alternativas políticas y escenarios climáticos. El análisis multicriterio evalúa la viabilidad de las prácticas agrícolas de mitigación en dos escenarios climáticos de acuerdo a la percepción de diferentes expertos. Los métodos estadísticos analizan los determinantes y las barreras para la adopción de prácticas agrícolas de mitigación. Las herramientas para el desarrollo de políticas basadas en la ciencia muestran el potencial y el coste para reducir GEI mediante las prácticas agrícolas. En general, los resultados de esta Tesis proporcionan información sobre la adaptación y la mitigación del cambio climático a nivel de explotación para desarrollar una política climática más integrada y ayudar a los agricultores en la toma de decisiones. Los resultados muestran las temperaturas umbral y la respuesta del arroz, el maíz y el trigo a temperaturas extremas, siendo estos valores de gran utilidad para futuros estudios de impacto y adaptación. Los resultados obtenidos también aportan una serie de estrategias flexibles para la adaptación y la mitigación a escala local, proporcionando a su vez una mejor comprensión sobre las barreras y los incentivos para su adopción. La capacidad de mejorar la disponibilidad de agua y el potencial y el coste de reducción de GEI se han estimado para estas estrategias en los casos de estudio. Estos resultados podrían ayudar en el desarrollo de planes locales de adaptación y políticas regionales de mitigación, especialmente en las regiones Mediterráneas. ABSTRACT Alterations in the climatic system due to increased atmospheric concentrations of greenhouse gas emissions (GHG) are expected to have important implications for agriculture, the environment and society. Agriculture is an important source of GHG emissions (12 % of global anthropogenic GHG), but it is also part of the solution to mitigate emissions and to adapt to climate change. Responses to face the challenge of climate change should place agricultural adaptation and mitigation strategies at the heart of the climate change agenda. Agriculture is crucial for the conservation and sustainable use of natural resources, which already stand under pressure due to climate change impacts, increased population, pollution and fragmented and uncoordinated climate policy strategies. The concept of climate smart agriculture has emerged to encompass all these issues as a whole. When assessing choices aimed at reducing threats to agriculture and the environment under climate change, two research questions arise: • What information defines smart farming choices? • What drives the implementation of smart farming choices? This Thesis aims to provide information on these broad questions in order to support climate policy development focusing in some Mediterranean agricultural systems. This Thesis integrates methods and tools to evaluate potential farming and policy choices to respond to mitigation and adaptation to climate change. The assessment involves both quantitative and qualitative approaches and integrates agronomic, climate and socioeconomic variables at local and regional scale. The assessment includes the collection of data on previous experimental evidence, and the integration of farmer behaviour and policy choices (e.g., technology, agricultural management and climate policy). The case study areas -- the Doñana coastal wetland (S Spain) and the Aragón region (NE Spain) – illustrate two representative Mediterranean regions where the intensive use of agriculture and the semi-arid conditions are already a concern. Thus the adoption of mitigation and adaptation measures can play a significant role for reaching a balance among equity, economic security and the environment under climate change scenarios. The multidisciplinary methodology of this Thesis includes a wide range of approaches for collecting and analysing data. The data collection process include revision of existing experimental evidence, public databases and the contribution of primary data gathering by semi-structured interviews with relevant stakeholders (i.e., public administrations, policy makers, agricultural advisors, scientist and farmers among others) and surveys given to farmers. The analytical methods include meta-analysis, water availability models (WAAPA model), decision making analysis (MCA, multi-criteria analysis), statistical approaches (Logistic and Poisson regression models) and science-base policy tools (MACC, marginal abatement cost curves and SOC abatement wedges). The meta-analysis identifies the critical temperature thresholds which impact on the growth and development of three major crops (i.e., rice, maize and wheat). The WAAPA model assesses the effect of climate change for agricultural water management under different policy choices and climate scenarios. The multi-criteria analysis evaluates the feasibility of mitigation farming practices under two climate scenarios according to the expert views. The statistical approaches analyses the drivers and the barriers for the adoption of mitigation farming practices. The science-base policy tools illustrate the mitigation potential and cost effectiveness of the farming practices. Overall, the results of this Thesis provide information to adapt to, and mitigate of, climate change at farm level to support the development of a comprehensive climate policy and to assist farmers. The findings show the key temperature thresholds and response to extreme temperature effects for rice, maize and wheat, so such responses can be included into crop impact and adaptation models. A portfolio of flexible adaptation and mitigation choices at local scale are identified. The results also provide a better understanding of the stakeholders oppose or support to adopt the choices which could be used to incorporate in local adaptation plans and mitigation regional policy. The findings include estimations for the farming and policy choices on the capacity to improve water supply reliability, abatement potential and cost-effective in Mediterranean regions.

Modelado experimental de un sistema de e-Salud aplicado en cooperación al desarrollo

Los Objetivos de Desarrollo del Milenio comprometieron a los países con una nueva alianza mundial de alcanzar gradualmente una cobertura universal de los niveles mínimos de bienestar en los países en desarrollo (reducir la pobreza y el hambre y dar respuesta a problemas como la mala salud, las desigualdades de género, la falta de educación, el acceso a agua salubre y la degradación ambiental). Para dar continuidad a esta iniciativa, recientemente en septiembre de 2015, la ONU promulgó la declaración de los Objetivos de Desarrollo Sostenible. Los ODM sitúan la salud en el corazón del desarrollo y establecen un novedoso pacto mundial que vincula a los países desarrollados y los países en desarrollo por medio de obligaciones claras y recíprocas. En este sentido, diversos organismos de cooperación a través de sus programas de cooperación internacional, tratan de mejorar el acceso a la asistencia sanitaria, especialmente a la población vulnerable que vive en zonas rurales de países en desarrollo. Con el fin de ayudar a cumplir los ODM que apoyan los temas de salud en dicha población, estos organismos desarrollan proyectos que despliegan sistemas de e-salud. Las intervenciones se enfrentan a múltiples retos: condicionantes de los países en desarrollo, las necesidades y demandas de los sistemas sanitarios y la complejidad de implantar las TIC en entornos complejos y altamente dinámicos como son los países en desarrollo. Estos condicionantes ocasionan la mayoría de proyectos fallidos que terminan convirtiéndose en soluciones aisladas, que anteponen la tecnología a las necesidades de la población y no generan el impacto esperado en su desarrollo. En este contexto tuvo origen esta tesis doctoral, que persigue como objetivo analizar, planificar, diseñar, verificar y validar un marco arquitectónico de implantación de sistemas de e-salud en áreas rurales de países en desarrollo, que promueva el mejoramiento de la calidad de vida de la población vulnerable de estas regiones y la efectividad de las intervenciones de e-salud en el marco de proyectos de cooperación al desarrollo. Para lograrlo, tomé como punto de partida, diversas estrategias, modelos, metodologías de implantación de e-salud, modelos de gestión de proyectos propuestos por distintos organismos internacionales y propuse una instanciación de estos modelos a proyectos de implantación de sistemas de e-salud en países en desarrollo. Apliqué la metodología action research y los enfoques twin track, middle out y design thinking que me permitieron el refinamiento iterativo del modelo propuesto en la tesis doctoral mediante el trabajo de campo realizado en dos zonas rurales de países de Centroamérica: Jocotán (Guatemala) y San José de Cusmapa (Nicaragua). Como resultado obtuve un modelo experimental basado en cuatro componentes: un modelo de referencia tipo, un modelo conceptual de e-salud, los procesos de gestión y de implantación de sistemas de e-salud en países en desarrollo y una arquitectura de referencia. El modelo experimental resultante aporta herramientas importantes para el despliegue de sistemas de e-salud en países en desarrollo. Se ha propuesto un modelo de referencia que proporciona una visión holística del contexto del país en desarrollo donde se desarrollarán las intervenciones. Un modelo conceptual de e-salud que representa los principales conceptos involucrados en un sistema de e-salud. Los procesos ii- de gestión del proyecto y de implantación del sistema que proporcionan a los grupos de cooperación, herramientas para el análisis, diseño, desarrollo y despliegue de los sistemas de e-salud en áreas rurales de países en desarrollo. Y finalmente la arquitectura de referencia que sienta las bases para la aplicación de estos procesos a un contexto en particular. Las líneas futuras de trabajo sugieren extender el modelo a más casos de estudio que permitan su refinamiento y evaluar los futuros usos que pueden surgir de los sistemas de e-salud resultantes. ABSTRACT Millennium Development Goals (MDGs) committing the countries with a new global partnership to achieve universal coverage of minimum levels of well-being in Developing Countries (for addressing extreme poverty in its many dimensions-income poverty, hunger, disease, lack of adequate housing, and exclusion-while promoting gender equality, education, and environmental sustainability). From September 2015, these goals are replaces with Sustainable Development Goals (SDGs). The MDG place health at the heart of development and establish a novel global compact, linking developed and developing countries through clear, reciprocal obligations. Many public and private institutions promote international cooperation programs to support in achieving the MDGs. Some of these cooperation programs deal improving access to healthcare to poor people living in isolated areas from developing countries. In order to accomplish this goal organizations perform projects (interventions or cooperation projects) that deploy e-health systems in these zones. Nevertheless, this kind of projects face multiple challenges that dismiss the effectiveness of the projects results. In particular, cooperation teams face issues such as constraints in developing countries, lack of electrical and ICT infrastructure, scarce transport, extreme climate conditions, lack ICT capacity, lack of access to healthcare and inefficient delivery methods, etc. Hence, these issues increase the complexity of implementing e-health in developing countries and then causes the most projects fail. In other words, the solutions do not meet population needs and do not generate the expected impact on development. This context is the starting point of this doctoral thesis, which deals with analysing, planning, designing, testing and validating an architectural framework in order to implement e-health systems in rural areas from developing countries, promote development of the population in these regions, and thus improve the impact of interventions of development cooperation projects. To achieve this goal, I took as a starting point the strategies, models, e-health implementation methodologies and projects management models proposed by various international agencies. Then I proposed an instantiation of these models to manage the intervention and implement e-health systems in developing countries. I applied the action research methodology and the approaches twin track, middle out and design thinking which allowed me the iterative refinement of the model proposed in this doctoral thesis. The proposed framework was validated by running two cases studies in rural areas of Central America: Jocotán (Guatemala) and San José de Cusmapa (Nicaragua). As a result, I obtained an experimental model based on four components: a Type reference model, an e-health conceptual model, both process management and implementation e-health systems in developing countries and a reference architecture. The resulting experimental model provides important tools for the deployment of e-health systems in developing countries. The model become as reference model that provides a holistic view of the developing countries context where the interventions will be running. The conceptual model of e-health represents the main concepts involved into an e-health system. The project management and implementation processes of the iv- system provide to the cooperation teams with tools for analysing, designing, developing and deploying e-health systems in rural areas from developing countries. Finally, the reference architecture provides the basis for the implementation of these processes into a particular context. The future research suggest the extension the model to other cases studies in order to refine and evaluate the viability the model.

La Revista El Arquitecto Peruano: reseña de la Cultura Arquitectónica del Perú 1937/1977

La tesis se centra en el análisis de 356 números de la revista El Arquitecto Peruano publicados entre 1937 y 1977. La revista fue fundada en agosto de 1937 por Fernando Belaúnde Terry, arquitecto graduado en la University of Texas at Austin en 1935 quien la dirigió por 25 años hasta marzo de 1963. Desde abril de 1963 la dirige Miguel Cruchaga Belaunde. Durante esta última etapa la revista deja de ser regular, publicándose intermitentemente con varios años sin editarse, hasta desaparecer finalmente en 1977. La revista es la publicación periódica de arquitectura más importante del siglo XX en el Perú. La investigación ubica a la revista en el contexto nacional donde se desarrolló vinculando además los diversos eventos de la arquitectura y el urbanismo del panorama internacional sucedidos durante las tres décadas de estudio. El trabajo empieza por establecer una secuencia de periodos. Esta se basa en la identificación de una estructura fija existente en la revista conformada por las secciones permanentes. Una paulatina inserción de secciones temporales fue complementando y detallando nuevas temáticas y contenidos generando variantes de la estructura fija a lo largo del tiempo. Como resultado de este proceso se reconocen 5 periodos vinculados a una serie de temas vertebrales durante la dirección de Fernando Belaunde: Periodo 1 (Agosto de 1937 a marzo de 1942). Vivienda Unifamiliar. Periodo 2 (Abril de 1942 a mayo de 1944). Urbanismo moderno. Periodo 3 (Junio de 1944 a diciembre de 1949). Vivienda Colectiva. Periodo 4 (Enero-febrero de 1950 a enero-febrero de 1956). Proyectos y obras. Periodo 5 (Marzo-abril de 1956 a enero-febrero-marzo de 1963). Territorio. Los años finales bajo la dirección de Miguel Cruchaga conforman el último Periodo. En la década de los treinta, durante el primer periodo se analiza el rol que un grupo de revistas de arquitectura europeas y norteamericanas tuvieron en la construcción formal y temática de El Arquitecto Peruano. En sus inicios existen influencias de The Architectural Forum, The American Architect, Architecture, California Arts and Architecture y Architectural Digest . Y junto a estas, las revistas alemanas Moderne Bauformen e Innen Dekoration. A raíz de la Segunda Guerra Mundial, las referencias a las revistas alemanas desaparecen y las relaciones con Estados Unidos se intensifican por la posición del Perú dentro del área de influencia norteamericana. El canal de las revistas no fue el único medio de influencia, durante los años cuarenta hubo un marco de apertura hacia Latinoamérica que incluyó viajes de cooperación de arquitectos norteamericanos por el sur del continente. Como parte de estos vínculos, en 1945 Paul Lester Wiener de Town Planning Associates y Richard Neutra, - ambos miembros del CIAM y el segundo Presidente del CIAM USA- prestaron asistencia a la iniciativa más importante promovida por la revista peruana, un proyecto de vivienda popular para obreros y empleados llamado el Plan Peruano. La revista tuvo siempre una fuerte actitud de cambio de la realidad existente en el medio peruano. Para modelar su nueva versión de la realidad instrumentó una serie de campañas de prensa. En la más importante utilizó las ideas del urbanismo moderno que circulaban durante la guerra nacidas en los CIAM de entreguerras. El Arquitecto Peruano aprovecha la coyuntura de los primeros años de la posguerra para canalizar sus iniciativas, tomando como modelo de su propuesta la idea de la Neighborhood Unit, convirtiéndolo en proyecto y finalmente construyendo la Unidad Vecinal N°3, el proyecto de mayor escala asociado con la revista. A esta perspectiva favorable para las ideas vertidas por la publicación se une el hecho de que su Director, es elegido Diputado por Lima y es un miembro muy cercano al gobierno de turno que dio la cobertura legal y de gestión para cristalizar los proyectos desde 1945 hasta 1948. Durante este periodo se producen las propuestas de mayor alcance promovidas por Fernando Belaunde y difundidas por la revista, como el propio Plan Peruano de Vivienda, los Centros Climáticos de Invierno, el Plan Piloto de Lima y los Concursos de Vivienda popular. Existe un trabajo anterior sobre la revista, restringido al campo del urbanismo realizado en 1992 por el historiador Antonio Zapata y titulado El joven Belaunde: Historia de la revista El Arquitecto Peruano en donde se inclina el peso de la revista hacia la Vivienda Social y se señala a Walter Gropius como el arquitecto más influyente en la publicación. La presente tesis plantea que el Plan Peruano es la punta del iceberg, pero que todos estos proyectos relacionados con la revista, conforman un conjunto indisoluble y que el paquete completo tiene una directa influencia de proyectos, ideas y labor editorial de José Luis Sert desarrollada desde finales de los años veinte hasta los años cincuenta. Sus libros Can Our Cities Survive? , The Heart of the City y la revista del GATEPAC AC Documentos de Actividad Contemporánea tienen improntas claras en la revista peruana que atraviesan tres de los periodos propuestos. Durante la década de los cuarenta cuando Sert junto a Wiener fueron socios en Town Plannning Associates y tuvieron contacto directo con el director de la revista así como con los principales colaboradores, y durante la década posterior. A la luz de las evidencias analizadas, la figura de José Luis Sert emerge como la del arquitecto más influyente para la revista El Arquitecto Peruano a lo largo de todo su recorrido. ABSTRACT The thesis focuses on the analysis of 356 issues of the magazine El Arquitecto Peruano published between 1937 and 1977. The magazine was founded in august 1937 by Fernando Belaunde Terry, graduated from the University of Texas at Austin in 1935 who leaded it 25 years until March 1963. Since April 1963 was leaded by Miguel Cruchaga Belaunde. During this last stage the magazine ceases to be published on regular times, being published intermittently, unreleased several years, and finally disappear in 1977. El Arquitecto Peruano is the most important magazine of architecture of the twentieth century in Peru. The research located the magazine in the national context where was developed further by linking the various events of architecture and urbanism of the international scene occurred during the three decades of study. The research begins to establish a sequence of periods. This identification is based on a fixed structure existing in the journal formed by the permanent sections. A gradual insertion of temporary sections was complementing and detailing new themes and contents generating variants of the fixed structure over time. As a result of this process we recognize five periods linked to a series of central themes developed under the lead of Fernando Belaunde: Period 1 (September 1937 to March 1942): The Small House. Period 2 (April 1942 to May 1944). Modern urbanism. Period 3 (June 1944 to December 1949). Housing. Period 4 (January-February 1950 January-February 1956). Projects and Buildings. Period 5 (March-April 1956 January-February-March 1963). Territory. The final years under the direction of Miguel Cruchaga make the last Period. In the thirties, during the first period, is analyzed the role that a group of European and American magazines in architecture had in formal construction and thematic of the magazine. In the beginning there are influences of The Architectural Forum, The American Architect, Architecture, California Arts and Architecture and Architectural Digest. And along with these, the german magazine Moderne Bauformen and Innen Dekoration. Following World War II, the references to german magazines disappear and US relations are intensified by the position of Peru in the area of US influence. The magazines was not the only ways of influence, during the forties there was an open framework with Latin America that included cooperation trips of american architects on the south of the continent. As part of these links, in 1945 Paul Lester Wiener of Town Planning Associates and Richard Neutra, -both members of CIAM and the second President of the CIAM USAassisted the most important initiative promoted by the peruvian magazine, a popular housing project for workers and employees called El Plan Peruano. The magazine always has a strong attitude of change of the reality in the peruvian scene. To model the new version of reality created a series of media campaigns. In the biggest it used the ideas of modern urbanism that circulated during the war born in the CIAM of twenties and thirties. El Arquitecto Peruano take advantage of the situation of the early postwar years to direct their initiatives, modeled his proposal with the idea of Neighborhood Unit, making project and finally building the Unidad Vecinal N° 3, the larger scale project linked with the magazine. This favorable outlook for the ideas expressed by the publication joins the fact that its Director is elected deputy for Lima and is very close member to the current government who gave legal instruments and management to crystallize projects from 1945 to 1948. During this period of far-reaching proposals promoted by Fernando Belaunde and diffused by the magazine, as El Plan Peruano itself, the Centros Climaticos de Invierno, the Plan Piloto for Lima and the Concusos de Vivienda Popular. There is an earlier work on the magazine, restricted to the field of urbanism in 1992 by historian Antonio Zapata, entitled El Joven Belaunde: Historia de la revista El Arquitecto Peruano where the weight of the magazine leans Social Housing and notes Walter Gropius as the most influential architect in the publication. This thesis suggests that El Plan Peruano is the end of the iceberg, but these related projects to the magazine, form an inseparable whole and that the whole package has a direct influence of projects, ideas and editorial work of José Luis Sert developed from late twenties to the fifties. His book Can Our Cities Survive? , The Heart of the City and the magazine of GATEPAC AC Documentos de Actividad Contemporanea have clear signs in the peruvian magazine cross three of the proposed periods. During the forties when Sert and Wiener were partners in Town Plannning Associates and had direct contact with the director of the magazine as well as with key colaborators, and during the following decade. In light of the evidence examined, the shape of José Luis Sert emerges as the most influential architect to the peruvian magazine along its entire route.
