Improved Synthesis of gamma-nitro-alfa-Amino ester and Acid Derivatives
No full textA useful microwave-assisted synthesis of γ-nitro-α-amino esters and corresponding acids, under mild conditions and without solvent, is described. The desired products were obtained via Michael addition from methyl N-(diphenylmethylene)-2,3-didehydroalaninate and commercially available nitroalkanes
Compiler testing using a sentence generator
No full textA system for assisting in the testing phase of compilers is described. The definition of the language to be compiled drives an automatic sentence generator. The language is described by an extended BNF grammar which can be augmented by actions to ensure contextual congruence, e.g. between definition and use of identifiers. For deep control of the structure of the produced sample the grammar can be described by step-wise refinements: the generator is iteratively applied to each level of refinement, producing at last compilable, complete programs. The implementation is described and some experimental results are reported concerning PLZ, MINIPL and some other languages

Grimmiaceae in the Early Cretaceous: Tricarinella crassiphylla gen. et sp. nov. and the value of anatomically preserved bryophytes
No full textBackground and Aims Widespread and diverse in modern ecosystems, mosses are rare in the fossil record, especially in pre-Cenozoic rocks. Furthermore, most pre-Cenozoic mosses are known from compression fossils, which lack detailed anatomical information. When preserved, anatomy significantly improves resolution in the systematic placement of fossils. Lower Cretaceous (Valanginian) deposits on Vancouver Island (British Columbia, Canada) contain a diverse anatomically preserved flora including numerous bryophytes, many of which have yet to be characterized. Among them is the grimmiaceous moss described here. Methods One fossil moss gametophyte preserved in a carbonate concretion was studied in serial sections prepared using the cellulose acetate peel technique. Key Results Tricarinella crassiphylla gen. et sp. nov. is a moss with tristichous phyllotaxis and strongly keeled leaves. The combination of an acrocarpous condition (inferred based on a series of morphological features), a central conducting strand, a homogeneous leaf costa and a lamina with bistratose portions and sinuous cells, and multicellular gemmae, supports placement of Tricarinella in family Grimmiaceae. Tricarinella is similar to Grimmia, a genus that exhibits broad morphological variability. However, tristichous phyllotaxis and especially the lamina, bistratose at the base but not in distal portions of the leaf, set Tricarinella apart as a distinct genus. Conclusions Tricarinella crassiphylla marks the oldest record for both family Grimmiaceae and sub-class Dicranidae, providing a hard minimum age (136 million years) for these groups. The fact that this fossil could be placed in an extant family, despite a diminutive size, emphasizes the considerable resolving power of anatomically preserved bryophyte fossils, even when recovered from allochthonous assemblages of marine sediments, such as the Apple Bay flora. Discovery of Tricarinella re-emphasizes the importance of paleobotanical studies as the only approach allowing access to a significant segment of biodiversity, the extinct biodiversity, which is unattainable by other means of investigation.Fil: Savoretti, María Adolfina.

MEIS, architetture per un museo. Concorso internazionale per il Museo Nazionale dell’Ebraismo Italiano e della Shoah di Ferrara
No full textIl progetto "Abitare il Museo" opera tre scelte: 1. Qualificazione del MEIS come struttura di ospitalità rendendo possibile l'esperienza attiva delle consuetudini della tradizione ebraica, del suo radicamento in Italia, con la realizzazione di un ostello per lo studio. 2. Conservazione integrale del complesso monumentale storico in cui ha sede,. 3. Innovazione/integrazione attraverso innesti a forte connotazione estetica ispirati all'alfabeto ebraico, ai suoi rapporti culturali e significati simbolici
