Growth patterns at distal radius and tibial shaft in pubertal girls: a 2-year longitudinal study.
2005
Bone changes, in terms of both size and BMD, were assessed longitudinally in pubertal girls. Before puberty, BMD at the distal radius declined, whereas bone size increased, suggesting that normal growing girls experience a transient period of increased bone fragility. This could explain the elevated low-trauma forearm fracture rates reported in earlier studies. Introduction: Longitudinal data on bone growth during puberty are sparse. Such information is needed to understand the sequence of biological changes, the physical and mechanical consequences for the growing skeleton, and the implications for later life. Materials and Methods: The geometric properties and volumetric BMD (vBMD) of the…
Some classes of topological quasi *-algebras
2001
The completion $\overline{A}[\tau]$ of a locally convex *-algebra $A [ \tau ]$ with not jointly continuous multiplication is a *-vector space with partial multiplication $xy$ defined only for $x$ or $y \in A_{0}$, and it is called a topological quasi *-algebra. In this paper two classes of topological quasi *-algebras called strict CQ$^*$-algebras and HCQ$^*$-algebras are studied. Roughly speaking, a strict CQ$^*$-algebra (resp. HCQ$^*$-algebra) is a Banach (resp. Hilbert) quasi *-algebra containing a C$^*$-algebra endowed with another involution $\sharp$ and C$^*$-norm $\| \|_{\sharp}$. HCQ$^*$-algebras are closely related to left Hilbert algebras. We shall show that a Hilbert space is a H…
Clarkson-McCarthy inequalities with unitary and isometry orbits
2020
Abstract A refinement of a trace inequality of McCarthy establishing the uniform convexity of the Schatten p-classes for p > 2 is proved: if A , B are two n-by-n matrices, then there exists some pair of n-by-n unitary matrices U , V such that U | A + B 2 | p U ⁎ + V | A − B 2 | p V ⁎ ≤ | A | p + | B | p 2 . A similar statement holds for compact Hilbert space operators. Another improvement of McCarthy's inequality is given via the new operator parallelogramm law, | A + B | 2 ⊕ | A − B | 2 = U 0 ( | A | 2 + | B | 2 ) U 0 ⁎ + V 0 ( | A | 2 + | B | 2 ) V 0 ⁎ for some pair of 2n-by-n isometry matrices U 0 , V 0 .
Da poeta a poeta, da traduttore a traduttore: il carteggio tra Umberto Saba e Tomàs Garcés
2015
Riassunto: Il rapporto personale tra Umberto Saba e Tomàs Garcés cominciò agli inizi degli anni Trenta e si interruppe poco prima della guerra civile spagnola. Quest’articolo analizza ed edita per la prima volta tutte le lettere scritte da Saba al poeta catalano che sono state conservate presso l’archivio della famiglia Garcés. Parole chiave: poesia, traduzione, Umberto Saba, Tomàs Garcés Abstract: The personal relationship between Umberto Saba and Tomàs Garcés began in the early thirties and stopped just before the Spanish Civil War. This article analyses and edits for the first time all the letters written by Saba to the Catalan poet that have been preserved in the archives of f…
Conversion of nadir, narrowband reflectance in red and near-infrared channels to hemispherical surface albedo
1997
Abstract Measured nadir-viewed narrow-band reflectanees in red and near infrared channels simulating AVHRR Channels 1 and 2 are compared with measured integrated solar spectrum hemispherical albedos. Reflectanees and albedos were measured from an aircraft over four widely different vegetation surfaces in southeastern Tasmania (Australia). A linear function is used to simultaneously correct for narrow band to broad band conversion errors and to convert nadir viewed reflectances to hemispherical albedos. While the application of the conversion equation presented is limited to the vegetation types of the study, the equation is independent of vegetation type. Results indicate that the reflectan…

La asistencia religiosa en centros penitenciarios y de internamiento de extranjeros
2017
El presente trabajo de investigación tiene como objeto el análisis de la fundamentación legal y de la realidad de la asistencia religiosa en establecimientos penitenciarios y en centros de internamiento de extranjeros (CIEs). El derecho a la asistencia religiosa de los internados en centros penitenciarios y de internamiento de extranjeros, como manifestación del derecho fundamental de libertad religiosa. El estudio busca responder a los siguientes interrogantes: ¿qué se entiende por asistencia religiosa y cuáles son sus claves de comprensión?; ¿cómo ha ido evolucionando la asistencia religiosa en lo centros de reclusión?; ¿cuál es el marco legal de la asistencia religiosa penitenciaria en E…
