Characterization and Quantitation of Carbon Black Nanomaterials in Polymeric and Biological Aqueous Dispersants by Asymmetrical Flow Field Flow Fract…

2021

Characterization of carbon black (CB) nanomaterials is required in industrial and research areas. Hence, in this study, asymmetrical flow field flow fractionation coupled to UV–vis and DLS detectors in series (AF4-UV–vis-DLS) was studied to evaluate the CB dispersion behavior in polymeric and biological dispersants, given the relevance of these media in practical applications. Under the experimental conditions, the results indicated that polymeric and biological dispersions showed size distributions with hydrodynamic diameters of 404 and 175 nm, respectively, for a particle core diameter of 40 nm. The polymeric dispersant provided lower stability as a function of time than that achieved by …

Differential Leakage Factor in Electrical Machines Equipped with Asymmetrical Multiphase Windings: a General Investigation

2019

This paper presents an investigation in terms of degree of unbalance and leakage factor of electrical machines equipped with multiphase windings. The analysis has been carried out through 4800 combinations between slots/poles/phases/layers, analyzing the variability of the leakage factor for each condition and determining the optimal region for its minimization. The obtained results demonstrate that the leakage factor could be considerably reduced with the adoption of slightly asymmetrical windings, which represent a favorable option during the early design stage of electrical machines.

EARLINET observations of the 14-22-may long-range dust transport event during SAMUM 2006: validation of results from dust transport modelling

2009

We observed a long-range transport event of mineral dust from North Africa to South Europe during the Saharan Mineral Dust Experiment (SAMUM) 2006. Geometrical and optical properties of that dust plume were determined with Sun photometer of the Aerosol Robotic Network (AERONET) and Raman lidar near the North African source region, and with Sun photometers of AERONET and lidars of the European Aerosol Research Lidar Network (EARLINET) in the far field in Europe. Extinction-to-backscatter ratios of the dust plume over Morocco and Southern Europe do not differ. Ångstr¨om exponents increase with distance from Morocco. We simulated the transport, and geometrical and optical properties of the dus…

Biometrical Analyses of a Sicilian Green Toad, Bufo siculus (Stöck et al. 2008), Population Living in Sicily (Italy)

2013

Se realizo un estudio morfometrico de la estructura del sapo verde siciliano de la Reserva Natural "Monte Pellegrino" (norte-oeste de Sicilia). Un total de 666 individuos (354 machos y 312 hembras) fueron capturados desde el ano 2003 durante la epoca de reproduccion. Se encontraron diferencias estadisticamente significativas entre los dos sexos, donde el peso corporal fue el mejor parametro (hasta 92% de clasificacion correcta), seguido por la longitud corporal (hasta 90% de clasificacion correcta). El uso simultaneo de todos los caracteres examinados solo aumento un 1% la probabilidad de una correcta discriminacion del sexo. En comparacion con la dimension de otras poblaciones de sapos ver…

ANALISI ARCHEOMETRICHE DELLA CERAMICA A DECORAZIONE GEOMETRICA DIPINTA E A VERNICE NERA

2018

Di seguito vengono esposti i risultati derivanti dalla caratterizzazione petrografica e chimica di 20 reperti ceramici costituiti da scodelle, bacini, tazze, coppe, brocche a decorazione geometrica dipinta datati dalla fine del VII sec. alla metà del V sec. a.C. (campioni siglati da ER-1 a ER-10) e da coppe/skiphoi decorati a vernice nera (campioni siglati da ER-11 a ER-20), datati dalla fine del VI al V sec. a.C.. Tutti i campioni analizzati provengono dal contesto di fondazione delle mura arcaiche di Erice (TP). L’approccio metodologico ha previsto la caratterizzazione degli impasti ceramici in termini tessiturali (addensamento e distribuzione dimensionale degli inclusi, natura ed omogene…

Experimental conditions for respiration and growth studies of F0 and F1 larval and juvenile European seabass Dicentrarchus labrax

2022

Water parameters in the 2 years before spawning of F0 (08.02.2016-06.03.2018) and during larval and juvenile phase of F1: Larval period until 17.05.2018 (48 dph, 900 dd) and 01.06.2018 (63 dph, ~900 dd) for warm and cold life condition respectively, for the juveniles until 28.09.2018 (180 dph, ~4000 dd) and 12.02.2019 (319 dph, ~5100 dd) for warm and cold conditioned fish respectively. Means ± s.e. over all replicate tanks per condition. Temperature (Temp.), pH (free scale), salinity, oxygen and total alkalinity (TA) were measured weekly in F1 and monthly in F0; sea water (SW) measurements were conducted in 2017 and 2018. Water parameters during larval and early juvenile phase of F0: Larval…
