Evidenze lessicometriche dal corpus Nulla dies sine linea
No full textL’obiettivo principale del progetto di ricerca Nulla dies sine linea è consistito nell’identificare oggettivamente le tendenze evolutive nella pratica della scrittura manuale in allievi della scuola primaria, in un periodo di circa quattro mesi, appartenenti a tre plessi scolastici di due Istituti Comprensivi del Comune di Roma, per un totale di 18 classi fra terza, quarta e quinta. I testi brevi analizzati nel contributo sono il prodotto di una traccia data agli scolari giorno per giorno. La lista degli argomenti assegnati è stata unica per tutte le clas- si interessate. È stato richiesto agli scolari di scrivere quattro righe di testo corsivo nella terza classe, cinque righe nella quarta e sei righe nella quinta
Cobitis linea
No full textCobitis linea (Heckel, 1848) (Fig. 18) Acanthopsis linea Heckel, 1848: 267 (type locality: Iran: creeks around Persepolis [Marvdasht Plain, about 70 km northeast of Shiraz]). Material examined. FSJF 2240, 15, 38–100 mm SL; Iran: Fars prov.: River Kor about 10 km south of Dashtak, 30.193 52.465.— FSJF 3219, 8, 32–39 mm SL; Iran: Shiraz prov.: Malous spring 10 km north of Shiraz, 29.877 52.481. Material used in molecular genetic analysis. FSJF DNA-1982, Iran: Shiraz prov.: Malous spring 10 km north of Shiraz, 29.877 52.482. (GenBank accession numbers: KP 050530, KP 050539). Diagnosis. Cobitis linea is distinguished from C. avicennae and C. kellei, two other species from the Persian Gulf basin, by having two laminae circularis in the male (vs. one). It is distinguished from C. elazigensis, the only other Cobitis species in the Persian Gulf basin having two laminae circularis, by the lack of an axillary pelvic lobe (vs. present) and the blotches in Z4 very small and roundish or comma-shaped along its whole length, densely set, often fused to short stripes or dissociated into an open field of several rows of small spots and blotches (vs. blotches in Z4 irregularly squarish, between vertical of pectoral-fin origin and dorsal-fin base, roundish and usually widely spaced posterior to the dorsal-fin base, not fused into stripes). Cobitis linea is distinguished from C. evreni and C. levantina by the blotches in Z4 very small and roundish or comma-shaped along the flank, densely set, often fused to short stripes or dissociated into a field of several rows of blotches (vs. blotches horizontally elongate or squarish anterior to the dorsal-fin origin, fused into a stripe in some C. levantina, Z4 is formed by a dark-brown stripe reaching from above the pectoral-fin base until the anus or beyond in C. evreni). Cobitis linea is further distinguished from C. evreni by the presence of the black spot at the uppermost caudal-fin base (vs. absent) and from C. levantina by the maxillary barbel reaching the vertical of the front margin or the middle of the eye (vs. not reaching). Distribution. Cobitis linea is endemic to the Kor River drainage, an endorheic basin in Central Iran. Remarks. Molecular data (Fig. 1) place Cobitis linea in a species group with C. aliyeae, C. anabelae, C. elazigensis, C. erkakanae, and C. levantina. Based on DNA barcoding it is well separated from all other included Cobitis and by a minimum K2P distance of 4.7% to C. elazigensis, also supported as PTP entity. See below for details to distinguish C. linea from other species in the C. linea species group.Published as part of Freyhof, Jörg, Bayçelebi, Esra & Geiger, Matthias, 2018, Review of the genus Cobitis in the Middle East, with the description of eight new species (Teleostei: Cobitidae), pp. 1-75 in Zootaxa 4535 (1) on pages 24-25, DOI: 10.11646/zootaxa.4535.1.1, http://zenodo.org/record/261577
SISTEMA DI CONTROLLO PER SEGNALI SISMICI TRASMESSI VIA LINEA TELEFONICA
No full textLa rete Sismica dell’Osservatorio Vesuviano – INGV è attualmente costituita da 28 stazioni analogiche a corto periodo (12 a tre componenti e 16 a componente verticale) e 3 stazioni digitali a larga banda (figura 1). La trasmissione dei segnali al centro di Acquisizione è effettuata prevalentemente mediante telemetria UHF; sei stazioni (NIS, STH, DMP, SFT, PE9 e TR9; figura 1) trasmettono i dati utilizzando linee telefoniche dedicate (Buonocunto et al., 2001). Al fine di migliorare il controllo sul funzionamento delle stazioni remote, negli ultimi anni sono stati sviluppati dal Laboratorio di Elettronica della Rete Sismica (U.F. Centro di Monitoraggio) una serie di sistemi automatici (Capello, 2001; Castellano et al., 2002). Tra le problematiche da affrontare relativamente alla diagnosi remota del funzionamento delle stazioni sismiche particolare attenzione è stata posta ai segnali trasmessi via linea telefonica. Infatti l’assenza del segnale presso il Centro di Acquisizione può essere dovuta sia ad un’avaria della strumentazione (es. rottura del modulatore, interruzione dell’alimentazione) che ad un’interruzione della linea telefonica.In questo rapporto viene descritto un apparato auto-alimentato che effettua un controllo remoto del sistema e che genera un segnale ad onda quadra di 3 Hz, modulato alla stessa frequenza portante della stazione sismica, in caso di assenza del segnale sismico. Il circuito in oggetto nasce con l’intento di analizzare la tipologia di guasto nei sistemi in trasmissione su linea telefonica dedicata e di capirne la natura al fine di ottimizzare gli interventi di manutenzione.INGV - Sezione di Napoli - "Osservatorio Vesuviano"Published1.1.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.
