On the senior authorship of Musca oleae (Diptera: Tephritidae)
No full textPietro Rossi (1738–1804), Professor at the University of Pisa, in 1790 described the olive fruit
fly Musca oleae in his opus Fauna Etrusca and for the next 121 years, Rossi was considered its
author. During all the 900 century, Gmelin was considered the senior author. In this paper we report that the date of Rossi's Fauna Etrusca has
been found to pre-date Gmelin's 13th Edition for the part that includes Musca oleae. Thus, we conclude that the senior author has to be considered definitively
Rossi and not Gmelin
On the evaluation of soil dynamic properties in centrifuge tests
No full textThis paper describes a method to compute the mobilised shear modulus, G, and
damping ratio, D, using the non-linear fit of experimental transfer functions obtained at
different depths in centrifuge models with the analytical expression of the amplification
function for a visco-elastic soil layer on a rigid base. The corresponding shear strain, ,
is computed as a function of the particle velocity and shear wave velocity. The sources
of potential error in the determination of G, D, and embedded in the proposed method
are identified and discussed in comparison with two other methods that have been
proposed in the literature, based either on the determination of the time lag of
accelerations between two accelerometers or on the evaluation of the shear stressshear
strain cycles from acceleration time histories recorded at different depths in the
model. The performance of the three methods is evaluated using the experimental data
obtained from nine centrifuge tests on dry sand. The values of G obtained by the
proposed method compare very well with the results of laboratory and literature data;
D values are more dispersed and slightly above literature data
Guidelines for comparing field or physical model observations with numerical simulations
No full textThis paper presents short report on the activities of TC204 Working Group on "Guidelines to compare field or physical model observations with numerical simulations". The main objective of the WG is that of proposing recommendations concerning the comparison between calculated and observed behaviour, specifically adapted for the type of works covered by TC204, i.e. tunnels and open excavations in soft groun
Camptopteroides (Camptopteroides) armata Viggiani 1974
No full textCamptopteroides (Camptopteroides) armata Viggiani, 1974 (Figs 26–30) Camptopteroides armata Viggiani, 1974: 4–6. Type locality: at 1400 m in a forested mountain E of Hatton (Nuwara Eliya District of Central Province), Sri Lanka. Camptopteroides armata Viggiani: Viggiani, 1989: 147 (illustration of male genitalia). Camptopteroides (Camptopteroides) armata Viggiani: Huber & Lin, 1999: 32. Diagnosis. MALE. Body dark brown; fore wing with uneven brown tinge. Antenna (Fig. 28) slender; scape with faint sculpture; flagellum 10-segmented, with fl 2 very short, ring-like, and all segments without mps but with setae. Mesoscutum with reticulate sculpture (Fig. 29). Fore wing (Fig. 30) with moderately pointed apex, 9.1× as long as wide, longest marginal seta about 3.3× maximum wing width. Digitus of genitalia with two spines. Type material. Holotype male (MHNG) on slide (Fig. 26) labeled: 1. “ Ceylon Hatton, 9.11.1970 1400 m. Montagne boisée à l’est de la ville. Tamisage au forêt”; 2. “ Camptopteroides armata n. gen. n. sp. Olotipe [sic] ♂ det. G. VIGGIANI 1974 coll. BESUCHET-LÖBL”; 3. “Prép. micr. MHNG No ENTO 84605”. Distribution. Sri Lanka. Remarks. This species is known from a single specimen, the holotype male, collected by the coleopterists C. Besuchet and I. Löbl by sifting in forest (almost certainly of soil and leaf litter and then extracting specimens using Winkler funnels). The holotype is poorly mounted in a darkened, water-soluble Faure medium. Only its digital images were examined (Figs 27–30).Published as part of Sankararaman, Hariharakrishnan, Manickavasagam, Sagadai, Triapitsyn, Serguei V., Huber, John T. & Kharbisnop, Bankerdonbor, 2020, Twonew species ofCamptopteroides Camptopteroides (Hymenoptera: Mymaridae) from the Oriental region with a key to Old World species, pp. 243-256 in Zootaxa 4868 (2) on pages 255-256, DOI: 10.11646/zootaxa.4868.2.4, http://zenodo.org/record/441763
Romagnosi’s Pedagogy and The Method of Political-Legal Education|LA PEDAGOGIA ROMAGNOSIANA E IL METODO DELL’EDUCAZIONE POLITICO-LEGALE
No full textThe aim of the article is to outline Romagnosi’s pedagogical thought, based on the teaching of law and the general renewal of legal studies. Although it is an intense and continuous commitment that extends throughout his mature life, Romagnosi does not disclose his own pedagogical teachings in specific treatises. These are then derived from some writings dedicated, on the one hand, to “civil philosophy” and, on the other, to the establishment of a course of study in legal studies
