Correspondence collected here includes Roditi’s professional correspondence with individuals as well as organizations.However, the bulk of the collection consists of art catalogues, press release, photographs, and exhibit invitations dealing with Jewish artists in France. These materials have not been microfilmed and are available in the original form. There are no personal materials that shed light on Eduard Roditi’s life, nor any materials pertaining to his work as an interpreter for the Nuremberg trial, or San Francisco Conference, during which the United Nations Organization was established.Edouard Roditi was born in France into an American family. He was educated in England, France, Germany, and in the United States. During WWII and shortly after he worked for a number of United States agencies.

    Sostenibilità e innovazione nello sviluppo turistico : Milano e la Lombardia

    No full text
    Il tema della sostenibilità del turismo e della sua promozione in modo innovativo a Milano e in Lombardia. Tra gli argomenti analizzati: il Nuovo Polo Fieristico; la specificità della certificazione ambientale degli enti locali; i modelli di valutazione della sostenibilità applicati dal Comune di Milano; il mutato paesaggio urbano e l’importanza dei nuovissimi city hotel. Presentazione del volume Diversi approcci teorici e metodologici affrontano il tema della sostenibilità del turismo e della sua promozione in modo innovativo a Milano e in Lombardia. Le molteplici sfaccettature del tema sono affrontate sotto il profilo dell'aumento della qualità e della diffusione del turismo sul territorio. Il Nuovo Polo Fieristico viene esaminato come nuovo polo turistico e della connettività globale nonché dell'inserimento della Lombardia nel mercato internazionale. Si analizza la specificità della certificazione ambientale degli enti locali e la comunicazione da parte delle amministrazioni pubbliche. Si studiano i modelli di valutazione della sostenibilità applicati dal Comune di Milano, la componente dell'ospitalità per l'applicazione professionale e le problematiche del passato e del presente del turismo sostenibile nella fascia delle Alpi centrali. Milano viene ancora illustrata sotto il profilo del mutato paesaggio urbano e dell'importanza dei nuovissimi city hotel come icone del paesaggio e motori di sviluppo, nonché come capitale dello stile e della moda quali grandi dinamizzatori dell'immagine di Milano. Le azioni di marketing territoriale delle Film Commission e il cineturismo ampliano il ventaglio dei punti di osservazione dell'azienda turismo. Il tema del turismo sostenibile attraverso diverse tematiche

    Expression of procyclin mRNAs during cyclical transmission of <i>Trypanosoma brucei</i>

    &lt;i&gt;Trypanosoma brucei&lt;/i&gt;, the parasite causing human sleeping sickness, relies on the tsetse fly for its transmission. In the insect, EP and GPEET procyclins are the major surface glycoproteins of procyclic (midgut) forms of the parasite, with GPEET predominating in the early procyclic form and two isoforms of EP in the late procyclic form. EP procyclins were previously detected on salivary gland trypanosomes, presumably epimastigotes, by immunoelectron microscopy. However, no procyclins could be detected by mass spectrometry when parasites were isolated from infected glands. We have used qualitative and quantitative RT-PCR to analyse the procyclin mRNAs expressed by trypanosomes in the tsetse midgut and salivary glands at different time points after infection. The coding regions of the three EP isoforms (EP1, EP2 and EP3) are extremely similar, but their 3′ untranslated regions contain unique sequences that make it possible to assign the cDNAs amplified by this technique. With the exception of EP2, we found that the spectrum of procyclin mRNAs expressed in the midgut mirrors the protein repertoire of early and established procyclic forms. Surprisingly, procyclin mRNAs, including that of GPEET, are present at relatively high levels in salivary gland trypanosomes, although the proteins are rarely detected by immunofluorescence. Additional experiments using transgenic trypanosomes expressing reporter genes or mutant forms of procyclin point to a mechanism of translational or post-translational control, involving the procyclin coding regions, in salivary gland trypanosomes. It is widely accepted that T. brucei always has a coat of either variant surface glycoprotein or procyclin. It has been known for many years that the epimastigote form does not have a variant surface glycoprotein coat. The finding that this life cycle stage is usually negative for procyclin as well is new, and means that the paradigm will need to be revis

    Il turismo in montagna : cronologie, modelli residenziali, apparati ricettivi : esempi dalle Alpi centrali

    L'articolo esamina le modalità e i tempi secondo cui l'interesse scientifico e culturale per le Alpi ha generato forme di frequenza nell'area da parte di un pubblico generico che, mosso inizialmente da interessi estetici, paesaggistici, antropologici, storici, è progressivamente passato, nel corso del XIX secolo, all'attività alpinistica e poi alla villeggiatura e al turismo invernale, inducendo sul territorio e nella società locali profonde trasformazioni

    Vacuum polarization for compactified QED4+1 in a magnetic flux background

    Get PDF
    We evaluate one-loop effects for QED4+1 compactified to R4×S1 in a nontrivial vacuum for the gauge field such that a nonvanishing magnetic flux is encircled along the extra dimension. We obtain the vacuum polarization tensor and evaluate the exact parity-breaking term, presenting the results from the point of view of the effective (3+1)-dimensional theory.Fil: Ccapa Ttira, Claudio.

    Cytochrome oxidase subunit VI of Trypanosoma brucei is imported without a cleaved presequence and is developmentally regulated at both RNA and protein levels

    Mitochondrial respiration in the African trypanosome undergoes dramatic developmental stage regulation. This requires co-ordinated control of components encoded by both the nuclear genome and the kinetoplast, the unusual mitochondrial genome of these parasites. As a model for understanding the co-ordination of these genomes, we have examined the regulation and mitochondrial import of a nuclear-encoded component of the cytochrome oxidase complex, cytochrome oxidase subunit VI (COXVI). By generating transgenic trypanosomes expressing intact or mutant forms of this protein, we demonstrate that COXVI is not imported using a conventional cleaved presequence and show that sequences at the N-terminus of the protein are necessary for correct mitochondrial sorting. Analyses of endogenous and transgenic COXVI mRNA and protein expression in parasites undergoing developmental stage differentiation demonstrates a temporal order of control involving regulation in the abundance of, first, mRNA and then protein. This represents the first dissection of the regulation and import of a nuclear-encoded protein into the cytochrome oxidase complex in these organisms, which were among the earliest eukaryotes to possess a mitochondrion
