Level structure above the 17+ isomeric state in 152 69 Tm83

2018

Excited states above the 17+ isomeric state in the proton-rich nucleus 152Tm were established by employing the recoil-isomer tagging technique. Data were collected using the JUROGAM gamma-ray array and the GREAT spectrometer together with the recoil ion transport unit (RITU) gas-filled recoil separator and analyzed to identify the prompt and delayed γ decays from the levels in 152Tm. Shell-model calculations, either in a large valence space or in a reduced model space with five protons in the π0h11/2 orbital and one neutron in the ν1f7/2 orbital, agree with the observed energies of the yrast levels up to angular momentum J = 21. The observation of near degeneracies in the energy spectrum ca…

L'implantation des gares TGV en France: tensions interscalaires, jeux d'acteurs et recompositions spatiales

2010

L’extension du réseau de lignes à grande vitesse renouvelle le problème du positionnement des gares, notamment en France qui privilégie une logique d’efficacité fondée sur des dessertes rapides et cadencées entre grandes métropoles au détriment des espaces intermédiaires. Cette option se traduit par deux types de localisation : gare principale centrale pour les plus grandes villes et gare périphérique pour les villes petites et moyennes. Ces choix d’implantation résultent de processus interactifs qui concernent tous les niveaux de l’organisation spatiale. Ainsi, si on examine les processus de décision ayant conduit à l’implantation des gares TGV en France, ces choix et les stratégies de val…

On Apache Log4j2 Exploitation in Aeronautical, Maritime, and Aerospace Communication

2022

Apache Log4j2 is a prevalent logging library for Java-based applications. In December 2021, several critical and high-impact software vulnerabilities, including CVE-2021-44228, were publicly disclosed, enabling remote code execution (RCE) and denial of service (DoS) attacks. To date, these vulnerabilities are considered critical and the consequences of their disclosure far-reaching. The vulnerabilities potentially affect a wide range of internet of things (IoT) devices, embedded devices, critical infrastructure (CI), and cyber-physical systems (CPSs). In this paper, we study the effects and feasibility of exploiting these vulnerabilities in mission-critical aviation and maritime environment…

Dicyclopentaannelated Hexa-peri-hexabenzocoronenes with a Singlet Biradical Ground State

2021

Abstract Synthesis of two dicyclopentaannelated hexa‐peri‐hexabenzocoronene (PHBC) regioisomers was carried out, using nonplanar oligoaryl precursors with fluorenyl groups: mPHBC 8 with two pentagons in the “meta”‐configuration was obtained as a stable molecule, while its structural isomer with the “para”‐configuration, pPHBC 16, could be generated and characterized only in situ due to its high chemical reactivity. Both PHBCs exhibit low energy gaps, as reflected by UV‐vis‐NIR absorption and electrochemical measurements. They also show open‐shell singlet ground states according to electron paramagnetic resonance (EPR) measurements and density functional theory (DFT) calculations. The use of…

El análisis marxista de las necesidades sociales

2018

The disappearance of the so-called «real socialism» has concealed the validity of the Marxist analysis of social reality. One of the sets of hypotheses that has best maintained its heuristic capacity is the Marxist theory of needs. The Marxist hypotheses have been developed in debate with other conventional conceptions. Currently, feminism and the ecological analysis of needs are renewing the views of Heller and Habermas.

Ligand mediated evolution of size dependent magnetism in cobalt nanoclusters.

2018

We use density functional theory to model the impact of a ligand shell on the magnetic properties of CoN (15 ≤ N ≤ 55) nanoclusters. We study three different ligand shells on each nanocluster core size, each known to have different electronic interactions with the surface: pure Cl ligand shells (X-type), pure PH3 ligand shells (L-type), and two component ligand shells with mixtures of Cl and PH3 ligands. The simulations show that the identity, arrangement, and total coverage of the ligand shell controls the distribution of local magnetic moments across the CoN core. On the surface of an unpassivated CoN nanocluster, the Co-Co coordination number (CN) is known to determine the local magnetic…

Increasing the drying efficiency of cylinder drying

2011

This PhD Thesis concentrates on paper drying: first on the drying rate in a cylinder covered with fabric, enhanced using hot air impingement through the fabric, and its potential effects on paper quality, and second, on the heat transfer rate from hot steam to paper through the cylinder shell. Cylinder drying is a drying method where a heated surface in contact with paper causes water removal from the latter by evaporation. Impingement through the fabric of hot air has been suggested to cause increase in the water removal and drying of paper. Increase in the drying rate by impingement of hot air was confirmed by laboratory tests and by simulations. In laboratory tests the increase in the dr…

2011

Il capitolo illustra le risultanze dello studio delle problematiche conservative e della caratterizzazione mineralogico petrografica dei materiali lapidei del teatro ellenistico di Morgantina (Enna). Tale attività è stata finalizzata alla definizione dell'intervento conservativo del teatro. The chapter illustrates the results of the study of conservation issues and petrographic mineralogical characterization of the stone materials of the Hellenistic theater of Morgantina (Enna). This activity was aimed at defining the conservative intervention of the theatre.

Dynamic tuning of the director field in liquid crystal shells using block copolymers

2020

When an orientationally ordered system, like a nematic liquid crystal (LC), is confined on a self-closing spherical shell, topological constraints arise with intriguing consequences that depend critically on how the LC is aligned in the shell. We demonstrate reversible dynamic tuning of the alignment, and thereby the topology, of nematic LC shells stabilized by the nonionic amphiphilic block copolymer Pluronic F127. Deep in the nematic phase, the director (the average molecule orientation) is tangential to the interface, but upon approaching the temperature TNI of the nematic– isotropic transition, the director realigns to normal. We link this to a delicate interplay between an interfacial …
