Rumores da escrita, vestígios do passado: uma interpretação fonológica das vogais do português arcaico por meio da poesia medieval

A proposta do presente livro é oferecer ao leitor uma descrição fonológica das qualidades vocálicas vigentes na primeira fase (período trovadoresco) do português arcaico a partir da análise das rimas e da grafia das Cantigas de Santa Maria, de Afonso X, o Sábio, Rei de Leão e Castela, elaboradas na segunda metade do século XIII.

As vogais postônicas do século XIII: um olhar sobre a escrita da época

This work aims to obtain a phonological description of unstressed word-final vowels of Medieval Portuguese (MP). The corpus of this research is comprised of Alfonso X’s Cantigas de Santa Maria, composed on the second half of the 13th century. This work maps all the graphemes that represent, in the corpus considered, the unstressed word-final vowels. From the analyses of writing and rhymes in Alfonso X’s Cantigas de Santa Maria, it was possible obtain some important information about the realization of the unstressed wordfinal vowels in MP.

Studies on the Helminth Fauna of Alaska. XIII. Disease in the Sea Otter, with Special Reference to Helminth Parasites

During the spring of 1951, the U. S. Fish and Wildlife Service undertook the removal of sea otter, Enhydra lutris (L)., from the Aleutian Island of Amchitka, for the purpose of restocking range from which the animals have long been exterminated. The decision to undertake this activity was influenced by the nature of military operations planned for the island later the same year. The capture and removal of the otter were under the supervision of Mr. Robert D. Jones, Biologist, U. S. Fish and Wildlife Service. Heavy losses among the animals shortly after capture made the venture unsuccessful. Many deaths were concurrent among animals in the wild state. The writer was asked to investigate the causes of disease in the sea otter, and it is the purpose of this paper to report the results of these investigation, with special reference to helminth parasites.

Synthetic and mechanistic investigation of new radical processes: reaction of organic azides with group-XIII Lewis acids

Dichloroindium hydride revealed to be a valid alternative to tributyltin hydride for radical reduction of organic (alkyl, aryl, acyl, solfonyl) azides. The new approach entails mild reaction conditions and provides high yields of the corresponding amines and amides, also showing high degrees of selectivity. The system dichloroindium hydride / azides can be utilised in fivemembered ring closures of g-azidonitriles, as a new source of aminyl radicals for the attractive synthesis of interesting amidine compounds in the absence of both toxic reagents and tedious purification procedures. Allylindium dichloride seems a good substitute for dichloroindium hydride for generation of indium centred radicals under photolytic conditions, since it allows allylation of electrophilic azides (e.g. phenylsulfonyl azide) and halogen or ester δ-substituted azides, the latter through a 1,5-H transfer rearrangement mechanism. Evidences of the radical nature of the reactions mechanism were provided by ESR spectroscopy, furthermore the same technique, allowed to discover that the reaction of azides with indium trichloride and other group XIII Lewis acids, in particular gallium trichloride, gives rise to strongly coloured, persistent paramagnetic species, whose structure is consistent with the radical cation of the head-to-tail dimer of the aniline corresponding to the starting azide.
