Progress in the Development of CdTe and CdZnTe Semiconductor Radiation Detectors for Astrophysical and Medical Applications
2009
Over the last decade, cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) wide band gap semiconductors have attracted increasing interest as X-ray and gamma ray detectors. Among the traditional high performance spectrometers based on silicon (Si) and germanium (Ge), CdTe and CdZnTe detectors show high detection efficiency and good room temperature performance and are well suited for the development of compact and reliable detection systems. In this paper, we review the current status of research in the development of CdTe and CdZnTe detectors by a comprehensive survey on the material properties, the device characteristics, the different techniques for improving the overall detector…
Una aproximación económica a las Sociedades Musicales
1999
El presente trabajo es un extracto de un primer paso para un proyecto de mayor profundidad que pretende realizar un estudio sobre la dimensión socio-económica de las Sociedades Musicales. Para ello, una vez puesta de manifiesto la relevancia y significación de las Sociedades Musicales en la Comunidad Valenciana, tratamos de encuadrar su compleja delimitación organizativa e institucional en el marco de la teoría de las organizaciones sin ánimo de lucro, aspecto éste que nos permite explicitar muchas de las características y funciones que definen las actividades de las sociedades musicales. Finalmente, a partir de la caracterización de las sociedades musicales como unidades no asistenciales m…

ChemInform Abstract: Tuning the Band Gap of PbCrO4Through High-Pressure: Evidence of Wide-to-Narrow Semiconductor Transitions.
2014
Commercial polycrystalline and cleaved platelets from natural PbCrO4 are studied in a diamond anvil cell at ≤ 21 GPa.
Langer-Giedion syndrome with interstitial 8q-deletion.
1982
We describe a 12-year-old girl with Langer-Giedion syndrome (tricho-rhino-phalangeal syndrome type II) who also had vertebral malformations. Chromosome analysis identified an interstitial del(8q): 46,XX,del(8)(pter leads to q22::q234 leads to qter) as a cause of this syndrome.
TECHNOLOGICAL PERSPECTIVES REGARDING THE APPLICATION OF THE CONTACT BREAKING ELECTRICAL DISCHARGE MACHINING PROCESS USING AS ELECTRODE-TOOL - METAL B…
2020
The scientific paper presents the most important aspects of theoretical and practical nature regarding the possibilities of processing metallic materials using the contact breaking electrical discharge machining with transfer object-metal band. The exposed research is based on the experience gained over the years by a team of Romanian researchers and university professors who managed to patent a metal material cutting plant using the process of contact breaking electrical discharge machining with transfer object-metal band. The scientific paper presents a radiography of some studies and research carried out over the years in the previous field presented.
Smadzeņu aktivitāte un volumetriskais ekrāns
2020
Maģistra darbs uzrakstīts angļu valodā uz 32 lappusēm. Tas satur 15 attēlus un ir atsauces uz 37 literatūras avotiem. Strauji attīstoties trīsdimensiju (3D) vizualizācijas tehnoloģijai ir nepieciešams precīzi novērtēt cilvēka spēju pielāgoties tai. Šādos pētījumos plaši tiek izmantots EEG. Pētījuma mērķis bija izpētīt smadzeņu aktivitātes īslaicīgās izmaiņas, skatoties uz volumetriskiem attēliem un salīdzinot ar anaglifa 3D attēlu aplūkošanu. Uzdevums bija noteikt tuvāk esošo apli starp četriem projicētiem apļiem. Smadzeņu aktivitātes signālu reģistrēšanai tika izmantots EEG. Izsaukto potenciālu P300 komponentē darba slodzes ietekmē netika novērotas būtiskas izmaiņas. Būtiskas izmaiņas tika…
Dynamic Role of Gold d-Orbitals during CO Oxidation under Aerobic Conditions
2022
High-energy-resolution fluorescence detection-X-ray absorption near-edge structure (HERFD-XANES) at the Au L3 edge was used to study gold catalysts supported on ceria in order to unravel the role of gold 5d orbital modifications during the activation of molecular oxygen. The variations in the HERFD-XANES resonance peak, which are directly correlated with the d-band occupancy, were monitored in situ during the redox process of the CO oxidation at room temperature under both aerobic and anaerobic conditions. Interestingly, upon the oxidation treatment and also during the aerobic CO oxidation treatment, the gold d-band fluctuates around an average value, proving that the gold clusters are part…
Patres non tantum natura. L'expositio di minori nelle declamazioni in lingua latina. Il caso di Ps. Quint. min. 278
2019
L’expositio di minori è notoriamente un motivo che torna con insistenza nella letteratura antica, greca e latina. Alcuni generi letterari come la commedia o il romanzo trovano una precisa ragion d’essere nell’abbandono di un minore, sicché l’evoluzione dell’opera viene di fatto a coincidere con i lunghi e complessi passaggi che porteranno al rinvenimento di tracce certe utili alla ricomposizione di nuclei familiari e alla riacquisizione alle famiglie di provenienza di giovani rimasti lungamente lontani. Nondimeno, questo accade anche nell'ambito della letteratura declamatoria; di un caso in particolare - la decl. min. 278 dello Ps. Quintiliano - ci s'intende occuparsi
