La tesis destaca la influencia que ejerció la teoría, las técnicas y la metodología de proyecto de los principales tratados de la época renacentista en la concepción, diseño y realización de algunos de los más importantes jardines de la época. Los tratados de Vitruvio, Alberti, Filarete, Di Giorgio, Serlio, Palladio, Colonna y Del Riccio establecen una nueva estética y una nueva visión del mundo, basadas en la geometría elemental y en los números simples. En la Grecia antigua, Platón y Pitágoras intuyeron la necesidad existencial del hombre de apoyarse en unas leyes seguras de orden superior. Sus teorías sobre las leyes del Universo son retomadas y aplicadas en el arte y en el jardín por Vitruvio y por los tratadistas del Renacimiento. Según los tratadistas, la estética es el núcleo generador del que se activan la información y las leyes hacia todos los campos del conocimiento y de la vida social y, por lo tanto, la finalidad de los tratados es buscar, a través de un procedimiento científico y racional, las reglas de la belleza. Las leyes estéticas formuladas por los tratadistas examinados se aplican con el mismo rigor y respeto ya sea al paisaje que al jardín, exaltando el elemento natural al igual que el construido (la ciudad y la arquitectura). De los tratados renacentistas se han extraídos términos y conceptos que ayudan a revalorizar, reinterpretar e integrar en el debate los temas del paisaje y del jardín. La tesis sostiene que: 1) una idea moderna de jardín se tiene que fundar en la historia; 2) que la historia es indispensable incluso para enfrentar el problema del mantenimiento y de la restauración de los jardines históricos; 3) que la teoría y las ideas que tienen valor, así como nos enseña Alberti, producen obras que también tienen valor; 4) la influencia de la estética de los tratadistas se encuentra incluso en algunos importantes jardines de época moderna y contemporánea. El capítulo 1 contiene la definición de tratado y la concepción estética del Renacimiento, analizada por medio de: a) la idea de ciencia y b) a través de las pinturas. Los capítulos 2 y 3 contienen respectivamente los principios teóricos de los tratados y el diseño, la metodología, las técnicas constructivas y los métodos de representación del proyecto según los tratadistas. Estos capítulos resultan propedéuticos de los capítulos siguientes por proporcionar el instrumento de lectura e interpretación de los jardines renacentistas y modernos. El capítulo 4 destaca la gran influencia de los tratados sobre las villas y jardines renacentistas y describe sus elementos. El último capítulo, el quinto, contiene un análisis de algunos jardines modernos. Entre ellos: Chiswick, la Villa “I Tatti”, Sutton Place, y la Villa “Il Roseto” que renuevan y prosiguen, en nuestra opinión, la lección de los tratadistas. El primer anexo contiene la propuesta de líneas de investigación que surgen a la luz de la tesis, y el segundo anexo contiene las noticias biográficas de los tratadistas examinados. ABSTRACT The thesis investigates the influence exercised by the theory, techniques and project methodology contained in the most relevant essays on art and architecture of the Renaissance on the concept, design and making of some of the most important gardens of that time. The essays of Vitruvius, Alberti, Filarete, Di Giorgio, Serlio, Palladio, Colonna y Del Riccio established a new concept of aesthetics and a vision of the world based on basic geometry and simple numbers. In ancient Greece, Plato and Pythagoras understood that humans needed “superior laws” to anchor their existences. Their theories on laws of the Universe were adopted and applied in art and gardening by Vitruvius and Renaissance essays authors. According to the authors of these essays, aesthetics represents the core generating information and laws that branch out toward all the fields of knowledge and social life. Therefore, the purpose of art and architecture essays consists in exploring, through a scientific and rational process, the rules of beauty. The laws of aesthetics proposed by the authors apply to landscaping and gardening with the same rigor and exalt the natural component as much as the artificial one (city and architecture). Several terms and concepts are also extracted that, despite their age, still help us to understand and enrich the contemporary debate revolving around landscaping and gardening. The thesis argues that: 1) the modern idea of gardening must be based on history; 2) history is fundamental even to address the topics of maintenance and restoration of historical gardens; 3) like Leon Battista Alberti maintains, valid theory and ideas produce valuable works; 4) the influence played by aesthetics on authors can be found in many important modern and contemporary gardens. Chapter 1 contains the definition of essay and of the Renaissance concept of aesthetics, analyzed by: a) the idea of science and 2) the analysis of some paintings of the period. Chapters 2 and 3 discuss respectively the theoretical principles of the essays and the design, methodology, construction techniques and the methods of representation of the project according to the authors. These chapters are preparatory toward the following chapters and provide us with the keys necessary to read and interpret Renaissance and modern gardens. Chapter 4 highlights the great influence exercised by those authors on the planning of important villas and gardens from the Renaissance while describing their elements. The 5th and final chapter analyzes some modern gardens among which Chiswick, Villa “I Tatti”, Sutton Place, Villa “Il Roseto”. These villas renew and in our opinion carry on the lesson of the essays written in the Renaissance. The first addendum suggests future lines of research derived from the thesis, while the second addendum contains biographical information regarding the authors examined.

On 22nd February '96, the space mission STS 75 started ,from the NASA facilities at Cape Canaveral. Such a mission consists in the launch of the shuttle Columbia in order to carry out two experiments in the space: the TSS 1R (Tethered Satellite Sistem 1 Refliight) and the USMP (United States Microgravity Payload). The TSS 1R is a replica of a similar mission TSS 1 '92. The TSS space programme is a bilateral scientific cooperation between the USA space agency NASA (National Aeronautics and Space Agency) and the ASI (Italian Space Agency. The TSS 1R system consists on the shuttle Columbia which deploys, up-ward, by means a conducting tether 20 km long, a spherical satellite (1.5 mt diameter) containing scientific instrumentation. This system, orbiting at about 300 km from the Earth's surface, represents, presently, the largest experimental space structure, Due to its dimensions, flexibility and conducting properties of the tether, the system interacts, in a quite complex manner, wih the earth magnetic field and the ionospheric plasma, in a way that the total system behaves as an electromagnetic radiating antenna as well as an electric power generator. Twelve scientific experiments have been assessed by US and Italian scientists in order to study the electro dynamic behaviour of the structure orbiting in the ionos phere. Two experiments have been prepared in the attempt to receive on the Earth's surface possible electromagnetic events radiated by the TSS 1R. The project EMET (Electro Magnetic Emissions from Tether),USA and the project OESEE (Observations on the Earth Surface of Electromagnetic Emissions) Italy, consist in a coordinated programme of passive detection of such possible EM emissions. This detection will supply the verification of some thoretical hypotheses on the electrodynamic interactions between the orbiting system, the Earth's magnetic field and the ionospheric plasma with two principal aims as the technological assesment of the system concept as well as a deeper knowledge of the ionosphere properties for future space applications. A theoretical model that keeps the peculiarities of tether emissionsis being developed for signal prediction at constant tether current. As a step previous to the calculation of the expected ground signal , the Alfven-wave signature left by the tether far back in the ionosphere has been determined. The scientific expectations from the combined effort to measure the entity of those perturbations will be outlined taking in to account the used ground track sensor systems.

This paper describes the preliminary results of an intercomparison of spectroradiometers for global (GNI) and direct normal incidence (DNI) irradiance in the visible (VIS) and near infrared (NIR) spectral regions together with an assessment of the impact these results may have on the calibration of triple-junction photovoltaic devices and on the relevant spectral mismatch calculation. The intercomparison was conducted by six European scientific laboratories and a Japanese industrial partner. Seven institutions and seven spectroradiometer systems, representing different technologies and manufacturers were involved, representing a good cross section of the todays available instrumentation for solar spectrum measurements.
