Academic literature on the topic 'Lemma access'

Il presente contribuito descrive la struttura e i contenuti del Glossario Bergamasco Medioevale di Antonio Tiraboschi, attualmente conservato presso la Biblioteca Civica Angelo Mai di Bergamo, e costituito da quattro quaderni manoscritti e inediti, all’interno dei quali sono registrati oltre 2000 lemmi organizzati alfabeticamente. Si descrivono le fonti, edite e inedite, dalle quali Tiraboschi attinge i frammenti citati all’interno di ciascun lemma e si propone una classificazione delle annotazioni di cui il Glossario si compone in tre sottogruppi: 
 
 note di carattere dialettologico, riguardanti gli esiti di forme latine o proto-romanze in italiano e nei dialetti gallo-italici (bergamasco, in primis) o relative alle particolari sfumature semantiche osservabili nel lessico del bergamasco;
 annotazioni di natura linguistica sulla comparsa di costruzioni romanze in sostituzione delle costruzioni latine, e sulle innovazioni semantiche romanze ravvisabili all’interno dei frammenti citati ad esemplificazione di ciascun lemma;
 osservazioni di carattere onomastico, relative a toponimi, microtoponimi e – più raramente – nomi personali.
 
 L’analisi condotta rappresenta un passo preliminare alla realizzazione di una edizione digitale (consultabile in modalità Open access a partire dalla home page della Biblioteca Civica Angelo Mai) dei preziosi materiali linguistici di cui il Glossario si compone e di una corrispondente edizione cartacea, che favoriscano valorizzazione e la fruizione del lavoro svolto dallo studioso bergamasco.
 
 Notes for an edition of Glossario Bergamasco Medioevale by Antonio Tiraboschi
 This paper describes the structure and the content of Antonio Tiraboschi's Glossario Bergamasco Medioevale, currently preserved at the Biblioteca Civica Angelo Mai in Bergamo, consisting of four manuscripts and unpublished notebooks containing more than 2000 alphabetically organized headwords. The sources, both published and unpublished, from which Tiraboschi drew the fragments cited as part of each lemma are described and a classification of the annotations into three subgroups is proposed: 
 
 notes of a dialectological nature, concerning either Latin or proto-Roman forms in Italian as well as in the Gallo-Italic dialects (Bergamasque, in primis) or relating to particular semantic nuances observable in the lexicon of Bergamasque;
 linguistic notes on the appearance of Romance constructions replacing Latin constructions and questionable Romance semantic innovations in the fragments cited as examples of each lemma;
 onomastic observations, concerning toponyms, microtoponyms and - more rarely - personal names.
 
 This analysis is preliminary step towards creating a digital edition (available in Open access mode from the home page of the Biblioteca Civica Angelo Mai) of the precious linguistic materials which compose the Glossary and a corresponding paper edition, which will favor the valorization and fruition of the work carried out by the Bergamasque scholar.

External surfaces of barley florets have thick-walled epidermal cells resistant to direct penetration by the head blight pathogen, Fusarium graminearum. Surfaces within the floral cavity have thin-walled, susceptible cells. How the fungus gains access to the floral cavity, causing head blight, has not been determined. To investigate pathways of entry, field-grown plants were sprayed with macroconidial inoculum after heads emerged from the flag leaf sheath and then were mist irrigated daily in the morning and evening. On selected days, 1 to 8 days after inoculation (DAI), 80 to 190 florets per day were harvested, dissected, and examined for presence and location of mycelial colonies. At 1 to 12 DAI, 57 to 100 florets likewise were examined for lesions. Patterns of colonization indicated that the fungus entered florets principally through crevices between the overlapping lemma and palea or through the apical floret mouth. The crevices were open for entry until ≈8 days after heads emerged. Most florets had mycelial colonies on the external surface in a sheltered pocket near the base of the ventral furrow of the palea. Mycelia spread laterally from the furrow to the crevice between lemma and palea. Anther colonization had only a minor role in invasion of florets. Hyphal penetration of stomates was not seen. Lesions usually developed first within 3 mm of the floret apex or 3 mm of the floret base. Within florets, lesions often were contiguous between lemma and palea, palea and caryopsis, or in all three floret parts. However, lesions in the caryopsis developed later and were fewer in number than in the lemma and palea and always were associated with lesions in the palea. The results show the importance of initial mycelial colonization of floret outer surfaces, pathways of entry via lemma or palea crevices or floret mouth, and spread of lesions within the floret at interfaces between lemma, palea, and caryopsis.
