Multiple Wesen
Full text linkAbstract in tedesco del Poster Multiple Wesen, esposto al Simposio internazionale „Lunar Base. Bauen fuer ein Leben auf dem Mond” tenuto a Kaiserslautern il 12-13 Maggio 2009.
Was baut man auf dem Mond? Wie baut der Erdmensch auf dem Mond? Wofür wird gebaut? Für wem wird gebaut? Welche Nutzungen, wie groß, welche Materialien? Man kann weiter fragen,... Sind dieses überhaupt die richtige Fragen? Kann man überhaupt vom Bauen auf dem Mond sprechen? Oder geht es darum, was der Mensch auf den Mond mit bringt, aus seiner Kenntniss, seinen Vorstellungen, seinen Träumen, seiner Erfahrung: was bringt er von dem Reich des Bekannten (der Erde) in das Reich des nur Vorstellbaren (dem Mond). Also: sich mit dem Mond zu beschäftigen - ausgenommen für die sehr wenigen, die schon dort waren – heißt, sich mit sich selbst zu beschäftigen, mit dem eigenen Wissen und dem Bild vom Mond. Alle Voraussetzungen, die einem irdischen architektonischen Entwurf zu Grunde liegen, fehlen; zu diesem Zeitpunkt kann man sich arbiträr Rahmenbedingungen geben: (Größe, wo, welche Nutzung, welche Lebensdauer, welche Materialien) so zu sagen ein Mondprojekt in einem Erdprojekt zu entwickeln, dadurch schnell eine „abgesicherte“, unangreifbare Lösung zu erlangen. Aber macht dieses Sinn? Bedeutet dies, die Spannung und die Erforschung des Neuen sowie das kreative Potential örtlicher Schwierigkeiten im Vorfeld auszuschließen? Wir schlagen vor, anstatt auf hiesige Fragen irdische Antworten zu formulieren, Strukturen zum Mond zu bringen; Raumstrukturen, die durch mentale Konzepte begründet sind, welche die vielen Fragen - auch welche die wir jetzt nicht zu fragen gewagt haben - aufnehmen können. Diese Strukturen, aber auch kleine räumliche Gebilde, helfen dem Vorstellungsvermögen der Forscher, Ingenieure, Wissenschaftler und alle Mondinteressenten. Neutrale Strukturen, ohne jetzt genau alle physische Eigenschaften festlegen zu wollen, sollen Raum werden können für Wohnen, Arbeiten, Forschen, Landen, Binden, Schützen, Aufbewahren, usw. - abhängig von den Fragen, die sich zu gegebener Zeit formulieren lassen und ständig ändern werden. Wir denken an sehr flexible Strukturen, die viel aufnehmen und aushalten können, sich sehr schnell transformieren lassen, also multiple Wesen, die zunächst die Vorstellung eines belebten Mondes anregen sollen. Dieser Strukturenkatalog soll dem Wissenschaftler zur Verfügung stehen, um das Mitdenken seiner räumlichen Bedürfnisse zu stützen.

Contributo degli studenti di Architettura al Simposio “Lunar Base - Costruire per una vita sulla
Luna”
A Kaiserslautern in Germania è in corso (12-13-maggio) il Simposio “Lunarbase - Bauen fuer ein
Leben auf dem Mond” (www.lunar-base.net) organizzato dalla DLR (Agenzia aerospaziale tedesca)
e dalla TU Kaiserslautern. Scienziati, ingegneri, architetti e designer di tutto il mondo presentano i
loro piani e le loro visioni per una possibile vita sulla Luna. Alcune nazioni tra le quali la Cina, la
Russia e gli Stati Uniti stanno elaborando piani concreti per la costruzione di stazioni lunari come
basi per missioni equipaggiate su Marte, con un orizzonte temporale intorno al 2020. La proposta
degli studenti dei Laboratori di I anno di Progettazione architettonica, tenuti dal Prof. Gaetano
Licata con la collaborazione del dottorando in Design Michele Cammarata nel nuovo corso di
Laurea triennale in Scienze dell’Architettura (SdA) e nel Corso di Laurea quinquennale (4/s), è stata
selezionata dal comitato organizzatore che ne ha richiesto l’elaborazione sotto forma di un Poster
(A0) attualmente esposto durante il Simposio. Si tratta di un montaggio di modelli tridimensionali
elaborati dagli studenti e denominati “multiple Wesen”. Questi modelli, in quanto concetti di
architettura assolutamente astratti, si prestano a contribuire a quel bagaglio di conoscenze, visioni,
sogni e immaginazione, che chiunque voglia “confrontarsi” con una realtà solo immaginabile come
quella della Luna, ha bisogno di “portare con sé” dalla Terra. Concetti mentali di spazi possibili –
“Raumstrukturen” - a sostegno degli scienziati, per poter continuare a immaginare insieme sempre
più concretamene la vita e la ricerca direttamente sulla Luna.

Piccole figure che passano
No full textCura e concezione del libro. Ricerca, selezione critica, e attualizzazione di testi, disegni e fotografie di Roberto Collovà, alcuni già pubblicati singolarmente e altri inediti."Piccole figure che passano" è un libro fatto di testi scritti tra il 1994 e il 2012, sull'architettura e sul mestiere dell'architetto, a partire da questioni specifiche legate a propri progetti e ricerche.
Apparentemente ogni scritto è un mondo a sé, può essere letto indipendentemente dagli altri, ma insieme forniscono uno spaccato delle questioni più importanti intorno all'architettura e alla città degli ultimi decenni. Allo stesso tempo il libro è una speciale biografia indiretta dell'autore e ne rintraccia le fondamenta teoriche del proprio lavoro di architetto
Risposta sismica di edifici prefabbricati isolati con dispositivi elastomerici
Full text linkThe paper concerns the seismic behavior of precast concrete industrial buildings with an elevation equipped with seismic isolators. It’s examined a building with rectangular plan of m 40x 50. The structure is constituted of columns of square cross-section of 0.6 m, with continuum beams foundation. The desk is made with T section beams for each frame connected by Gerber joints in the main direction and they support precast pre-tensioned tiles with shape. A plate of concrete is casted of the wing tiles for obtain a connected rigid deck.
At the top of the pillars will be placed rubber bearings having high dissipation capacity (HDRB).
The dynamic behavior of the structure under recorded real strong accelerograms is examined. In this work are considered Friuli, Loma Prieta, Northridge and Kobe accelerograms, dynamic incremental analysis are conducted in order to obtain the response of structure.
The concrete behavior is assumed with Mander law for the pillars, while the beams have a linear elastic behavior.
For the isolators a linearized constitutive law, using equivalent stiffness, is assumed.
The design criteria of isolated precast systems are highlight, in detail the use of isolators permit to reduce the dimensions and the reinforcing bars amount of pillars. It is need to connect the precast beams of the deck for obtain a rigid deck motion
Ancient immunity. Phylogenetic Emergence of recognition-defense mechanisms
Full text linkAlthough still scarcely considered by the majority of the biomedical world, invertebrates
have greatly contributed to the elucidation of fundamental biological problems. Let
us think to the birth of cellular immunology with Meˇcnikov’s experiment on sea star larvae,
or the importance of squids for the comprehension of the molecular basis of nerve conduction,
or the contribution of sea urchins to the studies of fertilization and early development.
Indeed, invertebrates represent the overwhelming majority of animal biodiversity and this
simple assumption can explain the growing interest of the scientific community towards
various aspects of their biology. Invertebrate immunobiology is one of such aspects.
Invertebrate immunity is of the innate type, which means without the somatic recombination
events occurring in lymphocytes of jawed vertebrates and accounting for the high
specificity of their responses. However, even if lacking the adaptive branch, this does not
mean that invertebrate immune systems are as simple as originally thought. Indeed, the
huge variety of adaptations led to a high diversification of the responses, and this Special
Issue, including two research papers and six reviews, presents some examples
Lessons in immunity: from single-cell organisms to mammals
No full textLessons in Immunity: From Single-cell Organisms to Mammals stems from the activity of the Italian Association of Developmental and Comparative Immunobiology (IADCI), represented by the editors. This book is presented as a series of short overviews that report on the current state of various relevant fields of immunobiology from an evolutionary perspective. The overviews are written by authors directly involved in the research, and most are members of the IADCI or have otherwise been involved in the related research for their respective overview. This publication offers scientists and teachers an easy and updated reference tool. Provides simple and updated reviews on the immunobiology of a wide spectrum of organisms, considered in an evolutionary context. ocuses on both cells and humoral components of a variety of non-classical model organisms. Offers in a single volume many contributions which can help with understanding the evolution of immune responses and the main adaptations in animal phyla Presents a valuable holistic cross-sectional approach for teaching immunology and its application
Univacuolar refractile hemocytes from the tunicate Ciona intestinalis are cytotoxic for mammalian erythrocytes in vitro
No full textA discontinuous, Percoll density gradient was used to separate hemocyte populations from the hemolymph of Ciona intestinalis. Hemocytes from each band were examined for their frequency, morphology, and cytotoxic activity against rabbit and sheep erythrocytes; results were expressed as a percentage of hemolysis. Statistical analysis revealed that only the 'univacuolar' granulocytes from Band 5, which contain a vacuole of refractile material, were cytotoxic. Cytotoxic activity was inhibited by sphingomyelin. For the first time in tunicates, lytic activity against erythrocytes was assessed by an assay based on plaque-forming cells. Plaques of lysis were revealed against rabbit erythrocytes but not against sheep erythrocytes
