Shortwave Ultraviolet Persistent Luminescence of Sr2MgSi2O7: Pr3+

2023

Currently, extensive research activities are devoted to developing persistent phosphors which extend beyond the visible range. In some emerging applications, long-lasting emission of high-energy photons is required; however, suitable materials for the shortwave ultraviolet (UV–C) band are extremely limited. This study reports a novel Sr2MgSi2O7 phosphor doped with Pr3+ ions, which exhibits UV–C persistent luminescence with maximum intensity at 243 nm. The solubility of Pr3+ in the matrix is analysed by X-ray diffraction (XRD) and optimal activator concentration is determined. Optical and structural properties are characterised by photoluminescence (PL), thermally stimulated lumi…

Virszemes ūdeņu sastāva raksturojums meža meliorācijas sistēmās uz kūdras augsnēm: Kalsnavas piemērs

2020

Biogēno elementu palielinātās koncentrācijas ūdensobjektos ir galvenais eitrofikācijas cēlonis. Lielākoties tie ūdensobjektos nonāk no lauksaimniecības zemēm, taču meža teritorijas aizņem ~52 % no Latvijas teritorijas, tādēļ būtiski novērtēt to ietekmi uz virszemes ūdeņu sastāvu. Meža meliorācijas sistēmu (MMS) ierīkošana Latvijas apstākļiem atbilstošajos meža tipos būtiski uzlabo kokaudžu ražību, padarot to par neatņemamu mežsaimniecības sastāvdaļu, taču arī intensificē barības vielu izskalošanos. Potenciālo ietekmes novērtēšanai, bakalaura darbā raksturots ūdens sastāvs sešos ģeogrāfiski atdalītos MMS sateces baseinos uz kūdras augsnēm un saistītajā ūdenstilpē – Vesetas upē, kā arī aprēķi…

The campomelic syndrome: review, report of 17 cases, and follow-up on the currently 17-year-old boy first reported by Maroteaux et al in 1971.

1983

We report 17 cases of the campomelic syndrome (CS) and a follow-up of one of the original patients of Maroteaux et al who is now 17 years old. Our review is based on 97 patients, including our own. An infant with the CS presents at birth with spectacularly short and bowed femora and tibiae. The initial chest radiograph confirms the diagnosis by demonstrating extremely small bladeless scapulae and hypoplastic pedicles of many thoracic vertebrae. Ossification of the sternal segments, pubis, talus, and knee epiphyses is also retarded. Usually the hips are dislocated and talipes equinovarus deformities are present. There is a small chondrocranium and a disproportionately large neurocranium. The…

OMBRE E «SCONFINAMENTI» NELLA POESIA DI LUCIO PICCOLO

2018

«Sognanti, lontane ombre», presenze incorporee, «memorie insaziate» sono le protagoniste più singolari della poesia di Lucio Piccolo. Nella concretezza monumentale del barocco palermitano, nelle campagne orlandine e negli interni casalinghi l'autore intraprende la sua ricerca di un «senso del trascendente», dell'oltre il limite. Tale «sconfinamento» poetico, il varcare la soglia dell'inesistente, si riconnette direttamente a quella riflessione sulla caducità del corpo e sull'inarrestabile trascorrere del tempo che tanta parte ha nella lirica piccoliana. La dimensione del trascendente viene sottoposta a un continuo processo di normalizzazione, privata dei connotati più terrificanti e accolta…

'A possible source for the seofonfealdan Godes gifa'. In M. SWAN. Essays for Joyce Hill on her Sixtieth Birthday

2006

L’articolo prende in considerazione l’omelia anglosassone ‘De septiformi spiritu’ attribuita ad Ælfric – con successiva rielaborazione di Wulfstan – e dimostra come la parte iniziale, in latino, finora ritenuta opera originale dello stesso Ælfric, sia in realtà ripresa fedelmente da un commento all’Apocalisse di Ambrogio Autperto.

The role of light in the emergence of weeds: using Camelina microcarpa as an example

2015

When modelling the emergence of weeds, two main factors are considered that condition this process: temperature and soil moisture. Optimum temperature is necessary for metabolic processes that generate energy for growth, while turgor pressure is necessary for root and shoot elongation which eventually leads to seedling emergence from the soil. Most emergence models do not usually consider light as a residual factor, but it could have an important role as it can alter directly or indirectly the dormancy and germination of seeds. In this paper, inclusion of light as an additional factor to photoperiod and radiation in emergence models is explored and compared with the classical hydrothermal t…

G. MELI, La Buccolica

2013

Nella letteratura europea del Settecento l’antica tradizione della poesia pastorale conosce una ripresa vigorosa e viene reinterpretata alla luce di interessi del tutto moderni: la riflessione sull’ordine cosmico e il suo sistema di forze inaugurata dalle ricerche newtoniane, l’approccio filosofico allo studio del tempo naturale e del tempo storico (regolati entrambi da un andamento ciclico), la diffusione dei modelli di sviluppo economico fondati sulle teorie fisiocratiche. In questa nuova prospettiva si colloca anche il progetto de La Buccolica di Giovanni Meli, poema composto di egloghe e idilli in dialetto siciliano, suddiviso in quattro sezioni intitolate alle stagioni dell’anno e pubb…

"Risuoni e risuoni o chimera": Amelia Rosselli dialogue avec les "Canti Orfici"

2015

International audience; Après avoir fait un bilan des éléments biographiques et poétiques qui permettent de rapprocher l’œuvre d’Amelia Rosselli de celle de Dino Campana, l’article examine la reprise parodique des vers du poète de Marradi contenue dans le poème « Per la tua pelle olivastra per la tua mascella cadente» tiré de "Variazioni belliche" (1964). Il montre ensuite que le dialogue avec les "Chants Orphiques" ne se confine pas aux reprises parodiques mais qu’il nourrit de façon souterraine toute l’œuvre d’Amelia Rosselli, dans les domaines lexical, syntaxique et rythmique. L’article considère enfin certains procédés stylistiques typiques de la poésie campanienne tels que l’itération,…
