Formability enhancement in incremental forming operations through sheet local heating

Single Point Incremental Forming: analysis of sustainability of the process through an experimental approach
2013
In literature, manufacturing processes have been studied with different approaches, but a lack of knowledge on the analysis of the energy required is still present. The aim of this paper is to carry out energy analysis on Single Point Incremental Forming process. Accordingly, a wide experimental investigation was executed by taking into account different process parameters (i.e. tool depth step, punch velocity and product shape). The total energy consumption was monitored during all the experiments and properly weighted with respect to the deformation energy, required to execute the process. A sensitivity analysis was also carried out to highlight the conditions which allow to save energy r…
Lectotypification of the spikemosses Selaginella denticulata and S. ornithopodioides (Selaginellaceae, Lycopsida)
2015
The typification of the names Selaginella denticulata (L.) Spring (≡ Lycopodium denticulatum L.) and S . ornithopodioides (L.) Spring (≡ L . ornithopodioides L.) (Selaginellaceae) is discussed. A specimen at LINN is designated as the lectotype of S . denticulata , and a specimen at BM is designated as the second-step lectotype of the name S . ornithopodioides .
Studies on the genus Atriplex (Chenopodiaceae) in Italy. VIII. Names published by Vincenzo Tineo and Michele Lojacono-Pojero
2023
The typification of the Atriplex names published by Vincenzo Tineo and Michele LojaconoPojero is discussed. Atriplex ambigua, A. dealbata, A. graeci, A. halimoides, A halimoides var. glomerata, A. halimoides var. perglauca, A. polyphylla, and A. ratundifolia are neo- or lectotypified on specimens preserved at FI or PAL and ynonymized with A. glauca (= A. dealbata), A. halimus (= A. halimoides = A. halimoides var. glomerata = A. halimoides var. perglauca), A. rosea (= A. ambigua = A. graeci) and A. tornabenei (= A. polyphylla = A. rotundifolia). The Tineo’s A. arenaria, previously considered as replaced synonym of A. tornabenei, is clarified and typified (neotype) on a specimens deposited at…
Nomenclatural notes on the Polycarpon tetraphyllum aggregate (Caryophyllaceae)
2015
Nomenclatural notes on the aggregate Polycarpon tetraphyllum (Caryophyllaceae) are discussed. The names Hagaea alsinifolia, H. polycarpoides, Poycarpon colomense, P. diphyllum, and P. floribundum are typified, respectively, on an iconography by Boccone (lectotype), and specimens preserved in PAL (neotype), JE (lectotype), MA (Herbarium Cavanilles, lectotype), and COI (Herbarium Willkomm, lectotype). For the nomenclatural purposes, the names P. bivonae (nom. nov. pro P. polycarpoides), P. herniarioides (holotype in K), P. peploides (nom. superfl. et nom. illeg. according to the Arts. 52.1 and 52.2 of the ICN), P. polycarpoides subsp. catalaunicum (holotype in BC), and P. rotundifolium (holot…
Typification of the name Eryngium siculum (Apiaceae)
2020
As part of an ongoing study on the names of vascular plants described from Sicily, a nomenclature study of the name Eryngium siculum Lojacono-Pojero (Apiaceae Lindl.), which appears to be yet untypified, is here presented.
Orobanche australis Moris ex Bertol. the correct name for O. thapsoides Lojac. (Orobanchaceae)
2022
The taxonomic relationships between Orobanche australis and O. thapsoides are analyzed through the study of the original material. These species are also compared with other morphologically similar ones occurring in the Mediterranean (O. canescens, O. pubescens, O. palaestina, O. amethystea). The lectotype of O. palaestina is designated. From the comparison of these taxa it is evident that O. australis and O. thapsoides refer to the same taxon, to which the name O. australis must be given by priority. The distribution of this species includes Sardinia, Sicily, Peninsular Italy and Southern France. It grows on pastures from the sea level to about 1000 m of altitude, host of Asteraceae. An id…
New records of the genus Orobanche L. (Orobanchaceae) to the Tunisian flora with lectotypification of the name O. rapum-genistae Thuill.
2023
Based on several field surveys and on the study of original material, we have identified three new species of Orobanche L. s.s. (Orobanchaceae) new to the flora of Tunisia. Orobanche alba Willd., O. calendulae Pomel, and O. gracilis Sm. are reported as new for the country, and the occurrence of O. rapum-genistae Thuill. is confirmed. The lectotypification of O. rapum-genistae is here proposed with a specimen housed in Genève (G). The geographical distribution of the four taxa in Tunisia is given, and details of habitats and hosts are provided. Altogether, the genus Orobanche in Tunisia now includes 18 species; a dichotomous key is proposed to facilitate the identification of these taxa.
La ricerca dei tipi di Michele Lojacono Pojero nell’ “Herbarium Mediterraneum Panormitanum”
2011
La ricerca del materiale originale dei nomi di piante descritte da Michele Lojacono Pojero viene qui commentato e vengono riportati i problemi incontrati nel lavoro svolto finora su Asteraceae e Orobanchaceae. Lojacono, autore della Flora sicula e di considerevoli contributi relativi preminentemente alla flora della Sicilia, è stato uno tra i più prolifici autori italiani di nomi di piante vascolari della fine XIX e inizio XX secolo.
