New case of the Richieri-Costa/Guion-Almeida syndrome
No full textWe describe a boy with multiple congenital anomalies/mental retardation (MCA/MR) syndrome. He has growth retardation, microbrachycephaly, coloboma of the iris, and typical facial anomalies including cleft lip/palate. This phenotype overlaps with that described by Richieri-Costa and Guion-Almeida in three Brazilian brothers. The new patient provides further evidence of the existence of this rare clinical entity
Sous-facteurs de L(F∞) d'indice 4cos2π/n,n≥3
No full textLet Q be a factor of type II1, λ a number in the Jones discrete series {4cosπ/m:m≥3}, and {ei} the Jones projections associated with λ. Denote by A2n and A1n the finite-dimensional von Neumann algebras generated, respectively, by {1,e2,⋯,en} and {1,e1,⋯,en}, with the corresponding traces. The author shows that, for n sufficiently large, the index of the inclusion An=(Q⊗A2n)∗A2nA1n⊂(Q⊗A2n+1)∗A2n+1A1n+1=An+1 is equal to λ (here ∗ denotes the reduced, amalgamated free product of the algebras in question). Using the random matrix model of Voiculescu, he proves that if Q is the von Neumann algebra L(F∞) of the free group with infinitely many generators, then An is isomorphic to L(F∞).
The two facts together imply the existence, for any λ in the Jones discrete series, of an irreducible subfactor of L(F∞) of index λ. This constitutes the first example of a nonhyperfinite, non-Γ II1 factor such that its Jones invariant is fully computable (the existence of nonirreducible subfactors of L(F∞) for any index ≥4 is a simple consequence of known results)
Gomphosphenia minima C. Delgado, S. Blanco, L. Gonzalez-Paz & S. F. P. Almeida 2022, sp. nov.
No full textGomphosphenia minima C. Delgado, S. Blanco, L. González-Paz & S.F.P. Almeida sp. nov. (Figs 2–7 LM, Figs 20–26 SEM) Description:— Frustules in girdle view wedge-shaped (Fig. 24). Valves slightly heteropolar, narrowly clavate to linear-lanceolate with narrowly rounded and not protracted headpole and footpole (Figs 2–7, 20, 23, 25, 26). Largest width near the mid-valve. Valve dimensions (n = 12): length 5.0–8.0 µm, width 2.2–3.0 µm. Axial area rather wide, lanceolate, widening slightly towards the central area (Figs 20, 23, 25, 26). Raphe is straight with slightly expanded drop-like proximal endings (Figs 21–23). Internally, proximal raphe endings are short, unilaterally deflected as small hooks (Figs 20, 22). Distal external raphe endings are very short, straight, slightly expanded into drop-like pores and not extended into the valve mantle (Figs 23, 25, 26). At LM view, striae are difficult to resolve due to the small valve size (Figs 2–7). Transapical uniseriate striae weakly radiate, becoming almost parallel mid-valve, 18–25 striae in 10 μm. Each stria is composed of a single transversely elongated areola both externally and internally (Figs 20–23, 25, 26). A row of individual pores (elongated in the pervalvar direction) is located on the valve mantle in girdle view (Fig. 24). Type:— PORTUGAL. Municipality of Coimbra, district of Coimbra, Centro region, Coimbra subregion: Candal stream, 40°4´44”N, 8°12´10”W, 10th February 2012 (holotype BM 81051! Natural History Museum, London, UK = Fig. 5; isotype: GDA 69158 University of Granada Herbarium, Granada, Spain). Etymology:— The specific epithet minima (from the Latin minimum: very little, very least) refers to the size of this taxon. Distribution and ecology:— Gomphosphenia minima was found in a few of the studied samples. From the 48 samples in the Candal stream, it only occurred in two samples from the same sampling point collected in February 2012 with an average abundance of 0.7 %. It was present in oligotrophic waters (370–910 μg∙L- 1 of nitrate), with neutral pH values (7.7), low electric conductivity (26.3–26.8 μS∙ cm-1) and low water temperature (3.8–8.1 ºC). Associated species: —The diatom assemblage of the type locality (Coimbra) was composed of different species such as Planothidium lanceolatum (Brébisson ex Kützing) Lange-Bertalot (1999: 287) (27.1 %; Figs 7–14), Eunotia minor (Kützing) Grunow (in Van Heurck 1881, figs 20–21) (17.3 %; Figs 19–22, 45), Planothidium frequentissimum (Lange-Bertalot) (in Lange-Bertalot 1999: 282) (16.8 %; Figs 15–18, 41, 42) and Sellaphora nigri (De Notaris) Wetzel & Ector (2015: 221, Figs 319–393) (11.4 %; Figs 23–33, 43, 44).Published as part of González-Paz, Lorena, Almeida, Salomé F.

Politica e amministrazione, tra etica, managerialità e responsabilità
No full textIl volume raccoglie le versioni, approfondite e rielaborate, delle relazioni discusse in occasione del convegno dal titolo “Politica e amministrazione. Etica, managerialità e responsabilità”, organizzato in onore di Gianfranco D’Alessio. L’oggetto di analisi, la dirigenza amministrativa, è discusso e analizzato, da un lato, in relazione ai principi costituzionali di imparzialità e di buon andamento della Pubblica Amministrazione e, dall’altro, al rapporto che questa instaura con gli organi politici. Il tema è affrontato con approcci variegati e da prospettive molteplici, secondo una impostazione che riflette la pluralità delle competenze e delle esperienze, professionali ed accademiche di ciascun autore.The volume collects the expanded and revised versions of the presentations discussed during the conference titled "Politics and Administration. Ethics, Managerialism, and Accountability," organized in honour of Gianfranco D’Alessio. The focus is on administrative leadership, discussed and analysed from two perspectives. Firstly, in relation to the constitutional principles of impartiality and good administration. Secondly, with reference to the relationship it establishes with political bodies. The topic is approached from various angles and multiple perspectives, reflecting the diversity of skills and experiences, both professional and academic, of each author
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

On head moderately dense, plumose, and long, semi-decumbent on clypeus and lower paraocular area, semierect to erect on remainder of paraocular area, frons and vertex; on disc of mesoscutum short, plumose, and semi-erect to semi-decumbent; on mesosomal pleura long, plumose, and semi-erect; T 1 –T 4 lacking hair bands either on tergal bases or on marginal areas; on S 1 –S 4 apical margins with fringes of long, dense, semi-erect, plumose setae; disc of metasomal sterna covered with a sparse vestiture of short, simple, and erect setae (a layer of large pollen grains covers a good part of the sternal surface, possibly associated to these setae); on outer surface of hind basitarsus, setae moderately short, semi-decumbent, and weakly plumose. Scopa well-developed on hind tibia, constituted by long setae, branched at their distal half and forming a tangle. Femoral corbicula (sensu Michener, 1999), surrounded by moderately long, erect, and plumose setae. Type series.

[upper band of label colored in yellow]” (1 ɗ); deposited at the Bee Collection of the Packer Laboratory, Department of Biology, York University, Toronto, Canada (PYU). Comments. Four nuclear gene loci of Andrenopsis michenerianus were sequenced for the phylogenetic study of Almeida and Danforth (in press): elongation factor 1 alpha (F 2 copy), LW-rhodopsin, wingless, and 28 S rRNA; respective GenBank Accession Numbers of these sequences are: DQ 884637, DQ 884538, DQ 884785, DQ 768526. A. michenerianus was positioned as sister of the other species of Andrenopsis included in the phylogenetic analyses of that study, and the two were placed as sister group of Neopasiphae (Fig. 1; Almeida and Danforth, in press). Etymology. This species is named in honor of Prof. Charles D. Michener, whose research on Australian bees lead to great advancement on the understanding of the systematics of Paracolletinae.Published as part of Almeida, Eduardo A. B., 2008, Revised species checklist of the Paracolletinae (Hymenoptera, Colletidae) of the Australian Region, with the description of new taxa, pp. 1-24 in Zootaxa 1891 on pages 18-24, DOI: 10.5281/zenodo.18435
