The guide compiles six separate inventories created by Don Messina, who digitized the recordings detailed in the guide. It includes a unique identifier for each recording, date, personnel, instrumentation, recording location, information about the original media carrier, song titles, related commercial releases, and commentary by Messina. Messina, a jazz bassist, performed with Mosca and worked closely with his associates and descendants to gather and research the recordings and create the guide.This guide describes subseries 3.5 of the Sal Mosca business records, audiovisual recordings, and realia (MC 074), Institute of Jazz Studies, Rutgers University Libraries
Data on the positive synergic action of dimethylacetamide and trehalose on quality of cryopreserved chicken sperm
AbstractThis data article contains supporting information regarding the research article entitled “Combined effect of permeant and non-permeant cryoprotectants on the quality of frozen/thawed chicken sperm”(Mosca et. al., 2016) [1]. The combined effect of the permeant cryoprotectants agent dimethylacetamide and the non-permeant cryoprotectants agent trehalose on the quality of frozen-thawed chicken semen was assessed. In particular, the quantitative dimethylacetamide/trehalose ratio was investigated freezing semen samples according to the following treatments: trehalose 0.1M+0% dimethylacetamide (DMA-0), trehalose 0.1M+3% dimethylacetamide (DMA-3), trehalose 0.1M+6% dimethylacetamide (DMA-6)
Specificity of Dissociative Disorders in Survivors of Torture and Extreme Trauma: Identification of Some Specific ‘‘Clusters’’ in the Dissociative Experience Scale
In recent years several studies have shown the high incidence of dissociative symptoms in subjects who experienced extreme trauma, such as torture or prolonged physical or psychological abuse. These processes are now considered as a specific and central consequence of repeated interpersonal trauma. Thus, new nosographic categories have been formulated to overcome the concept of PTSD (Complex PTSD, Extreme Stress Disorder). The clinical research we carried on in our Centre explored the psychopathological consequences of extreme trauma.
Dissociative experiences were evaluated in a clinical population of 80 asylum seekers who had survived extreme trauma within the 12 months prior to the study. Every patient completed an assessment based on a specifically oriented semi-structured interview and a psychometric evaluation, including the Dissociative Experiences Scale.
Previous studies suggested the possibility to identify a specific pattern of dissociative experiences in victims of extreme trauma. The statistic elaboration of our cluster analysis of the DES, compared to a matched control population of asylum seekers with no previous experience of extreme trauma, highlights specific dissociative phenomena in the clinical group. If these results will be confirmed in future more extended studies, they could lead
towards a specific scale for post-traumatic dissociative experiences
Graft rejection after femtosecond laser-assisted deep anterior lamellar keratoplasty: report of 3 cases.
PURPOSE:
To report 3 cases of stromal rejection after deep anterior lamellar keratoplasty (DALK) assisted by a femtosecond laser.
METHODS:
Three keratoconus eyes of 2 men (22 and 30 years old) and 1 woman (24 years old) who had DALK with a 60-kHz femtosecond laser developed intrastromal graft rejection with superficial and deep neovascularization after 6, 15, and 12 months, respectively. All patients underwent confocal microscopy and were treated with topical steroid therapy.
RESULTS:
In vivo confocal microscopy revealed cellular inflammatory infiltrates in the subepithelial and middle stroma of the donor lamella without involvement of the endothelium. Graft rejection was rapidly reversed with topical steroid therapy, and a clear cornea was restored in all cases.
CONCLUSIONS:
Graft rejection remains a significant complication of lamellar surgery but is associated with good tissue restoration and complete visual recovery
La variazione linguistica in Europa attraverso un database tipologico. L’esperienza del Pavia Typological Database
L’uso di risorse elettroniche per documentare e descrivere fenomeni linguistici è una pratica ormai consolidata nella linguistica quantitativa, dati i vantaggi che un ausilio computazionale comporta in termini di velocità e precisione nella raccolta dei dati. L’estensione di tali strumenti ad ambiti di ricerca più tradizionalmente legati allo studio qualitativo del dato linguistico, come la tipologia, è invece più recente.
Obiettivo di questo articolo è analizzare il ruolo dei database elettronici nella ricerca tipologica, combinando riflessioni di natura teorica più generale con l’esperienza specifica del Pavia Typological Database (in seguito PTD, cfr. §2), un database che raccoglie e rende accessibili dati relativi ad alcuni fenomeni morfosintattici delle lingue d’Europa. Descrivendo la struttura, le problematiche e le soluzio-ni che hanno caratterizzato la creazione del PTD, intendiamo evidenziare i vantaggi che un database e-lettronico può portare alla comparazione interlinguistica e tipologica

Through the re-examination of known records and the analysis of unprecedented evidences, the author focuses on still problematic aspects regarding the history of viridarium and, particularly, on the role that the building may have played in pope Paul II’s plans for the Palace of San Marco in Rome
Increased root growth and nitrogen accumulation in common wheat following PGPR inoculation: Assessment of plant-microbe interactions by ESEM
The use of plant growth-promoting rhizobacteria (PGPR) meets the current need to reduce nitrogen input in order to attain greater sustainability in the production of crops, particularly cereals. This study investigated whether a commercial bio-fertiliser containing a consortium of PGPR and N-fixing bacteria (Azospirillum spp., Azoarcus spp. and Azorhizobium spp.) affects shoot and root growth, N accumulation and grain yield in common wheat (Triticum aestivum L.).
Trials were conducted in a fertile, silty loam soil, firstly in rhizoboxes, by applying bacteria either as a seed- coating inoculum or by foliar + soil spraying, and then in the field by spraying the canopy at the tillering stage with decreasing levels of N fertilisation (160, 120 and 80 kg ha−1) in two consecutive years. Culm height, leaf chlorophyll content, nitrogen accumulation and yield were recorded above ground, while below ground Root Length Density (RLD) patterns were investigated by soil coring and image analysis at the flowering stage. Environmental Scanning Electron Microscope (ESEM) imaging revealed an excellent ability of bacteria to adhere to the surface of intact leaves and roots, and to colonise both leaf mesophyll and root vascular tissues in aseptic conditions. Bacteria increased the number of root tips and ramifications (+65% vs. non-inoculated controls) in sterilised rhizobox soil, regardless of the method of application, and the volumetric root length density in the open field with medium (+29%) and high (+11%) N supply, resulting in greater N accumulation (about +25 kg ha−1). Although the N dose had clear positive effects, no significant variations in grain yield (only + 1–3% vs. non-inoculated controls) or other agronomic parameters could be ascribed to bacteria inoculation.
The conclusion drawn is that the use of a combination of PGPR and N-fixing bacteria offers an opportunity to improve root growth in wheat and increase plant resilience to environmental stresses, and helps to reduce N losses from agricultural ecosystems thereby offering partial fertiliser savings within crop rotations
GeoGebra e le curve di Bézier
Le curve di Bézier sono delle importanti curve parametriche, studiate nel campo matematico dell’Analisi Numerica, molto utilizzate nella Computer Grafica. Esse prendono il nome dall’ingegnere francese Pierre Bézier che nel 1962 le usò per disegnare le carrozzerie delle automobili, ma vennero realizzate già nel 1959 da Paul de Casteljau utilizzando l’algoritmo che porta il suo nome.
Le grandi potenzialità del software GeoGebra consentono di disegnare queste curve sia attraverso un metodo grafico, sia con l’utilizzo dell’algoritmo di de Casteljau.
GeoGebra infatti permette di lavorare simultaneamente in diversi ambiti matematici, quali l'Algebra e la Geometria, mentre l'uso del foglio elettronico, fornendo anche una simultanea visualizzazione grafico-geometrica degli oggetti, facilita la comprensione delle proprietà algebriche. Sfruttando le proprietà dinamiche del software è inoltre possibile realizzare costruzioni che riproducano passo a passo gli algoritmi studiati e, trascinando gli enti geometrici che intervengono nella costruzione, avere un riscontro immediato su come essa si
modifica.
Il lavoro “GeoGebra e le curve di Bézier” verte in particolare su due differenti procedimenti che possono essere seguiti per disegnare le curve di Bézier mediante tale software.
Il primo consiste nel costruire le curve quadratiche come inviluppo delle tangenti partendo da tre punti di controllo; nel secondo metodo viene applicato esplicitamente l’algoritmo di de Casteljau per disegnare una curva cubica partendo da quattro punti di controllo
