L'attualità della "ecclesiologia fondamentale" della Lumen gentium: invito a una rilettura in chiave del simbolismo cristologico-trinitario

Il presente contributo riflette sulla Lumen gentium dal punto di vista della sua attualità. Questa viene cercata non tanto nelle singole prese di posizione o formulazioni della Lumen gentium, considerate importanti perché in grado di stimolare l'ecclesiologia postconciliare. L'attualità che sta al centro dell'interesse dell'Autore viene intravista piuttosto nell'impostazione ecclesiologico-ermeneutica di fondo della costituzione. Si parte dal presupposto che tale impostazione si stagli con sufficiente chiarezza quando la Lumen gentium viene interpretata in quell'orizzonte fondamentale di pensiero, che fu adoperato dai padri conciliari per elaborare le loro riflessioni su tutti i grandi temi della dottrina cattolica. Esso consiste nella centralità ermeneutica della Rivelazione di Dio triuno in Gesù Cristo, ossia nel voler trattare ciascun tema, inclusi i temi di ecclesiologia, sub Revelationis luce. L'Autore si impegna a sviluppare l'interpretazione della Lumen gentium a partire da come questo presupposto viene concretizzato da K. Rahner. Il teologo gesuita considera, infatti, la Rivelazione trinitaria centrale per la teologia proprio per il fatto che essa permette di elaborare un pensiero credente adeguato, fondato sulla visione della persona di Cristo come "simbolo reale", in quanto in Lui si manifesta realmente Dio Padre. Secondo Rahner, ciò che vale di Cristo, vale anche della Chiesa, essendo essa "simbolo reale" della presenza di Cristo i mezzo agli uomini. Alla luce di una tale visione della Chiesa, l'Autore fa vedere come nella Lumen gentium è presente, in effetti, una prospettiva ermeneutica che segue la logica del "simbolo". Essa emerge in modo esplicito o implicito laddove, nella costituzione, viene tematizzato il rapporto tra vescovo e collegio dei vescovi, vescovo e Chiesa locale, Chiesa locale e Chiesa universale e via dicendo, rapporto per il quale vale che una realtà è simboleggiata dall'altra. Interpretare la Lumen gentium in questi termini significa ammettere che la Chiesa e tutto ciò che essenzialmente fa parte di essa sono di indole "simbolica". L'Autore cerca di dimostrare, che al centro di tale comprensione simbolica della Chiesa e degli elementi di ecclesialità sta, in ogni caso, quella verità che è centrale per la simbolicità della persona di Cristo: la Sua sostanziale identità relazionale di origine trinitaria. Questa verità porta a dover affermare che tutto ciò che è ecclesiale è sostanzialmente relazionale

O “canto do cisne” do Leonardo da Vinci russo: introdução à obra carcerária de Pavel A. Florenskij

P. A. Florenskij (1882-1937), pensador e cientista russo, reconhecido pelo seu poliédrico interesse no campo do conhecimento, foi um dos defensores da necessidade de um pensamento capaz de aproximar e descrever o real em sua multiforme complexidade. O eloquente e convincente testemunho deste pensamento é a sua copiosa e ampla produção filosófico-teológica e científica. Em 1933, quando regime soviético decidiu levar Florenskij para a prisão em um campo de concentração, as cartas escritas aos familiares tornaram-se ocasião para que ele pudesse refletir pela última vez sobre aquelas intuições originais que estavam na base do seu projeto sobre o “pensamento integral”. Este artigo pretende mostrar como esta particular intenção — com suas características e aplicações — está presente na correspondência carcerária. O objetivo principal será apresentar as cartas do gulag como uma obra que consegue concretizar o ambicioso e sempre atual projeto de Florenskij em um modo lúcido e exemplar, demonstrando sua funcionalidade até mesmo nas condições dramáticas e proibitivas de vida e trabalho

Editors' Introduction

The thought of P.A. Florensky is a peculiar expression of Russian philosophy and, more generally, of Russian cultural identity. At the same time, it can nevertheless be regarded as a legitimate heir to the cultural tradition which from its powerful Ionian roots unfolds through the peaks and abysses of Western philosophy stricto sensu, up to the ultimate crises of contemporary thought..

NdFeB permanent magnets with various Nd content

Three kinds of commercial Nd-Fe-B based materials were compared using 57Fe Mössbauer spectroscopy and X-ray analysis: near the Nd 2Fe14B stoichiometry and with both lowered and raised Nd content. Magnetically hard Nd2Fe14B is present in all three materials. In the Nd-low material it is accompanied with the magnetically soft Fe3B phase, building the nanocomposite structure. In the Nd-rich sample the overstoichiometric Nd atoms seem to build separate phase of Fe-Nd solid solution. None of the materials contain significant content of phases degrading magnetic characteristics, with except of minor Nd1.1Fe 4B4 one

STRUCTURE AND PROPERTIES OF NANOSIZE NiFe2O4 PREPARED BY TEMPLATE AND PRECIPITATION METHODS

Nanosize NiFe2O4 was prepared by template method and precipitation process using same starting materials. The use of soluble starch in both synthesis routes was investigated. The amount of the used precipitating agent (Na2CO3) for the precipitation approach was selected according to two adopted scenarios based on theoretical and average yield of possible side reaction expressed by the degree of substitution (DS). The results of SEM microstructural analysis of the prepared Ni-ferrite powders demonstrate evident influence of the applied preparation method whereas high-magnification FE-SEM images show very similar fine-grained structures characterized by different size of particles. According to the results of XRD analysis, the obtained ferrite powders exhibit only slight differences in phase composition with calculated crystallite size for template sample d(XRD) = 36 nm and for the both precipitation route samples d(XRD) = 21 nm. Additional sample characterization using Fe-57 Mossbauer spectroscopy supports the findings of the microstructural and XRD analysis. The "clearest" spectrum was obtained for the template sample while the strongest influence of nanocrystalline component was observed for the sample prepared with maximal amount of precipitation agent (DS=3). The room temperature magnetic hysteresis loops, recorded using vibrating sample magnetometer (VSM), are very similar and exhibit characteristic shape with values of magnetic properties within expected range for this type of material

Temporomandibular Disorders and Orthodontic Treatment Need in Orthodontically Untreated Children and Adolescents

The aim of this study was to explore the association between signs and symptoms of temporomandibular disorders (TMD) and orthodontic treatment need in orthodontically untreated children and adolescents. One thousand fi ve hundred and ninety-seven subjects aged 11–19 years, without previous orthodontic history, from sixteen randomly selected public schools in Zagreb, Croatia, were examined. Malocclusion characteristics were assessed by using the criteria proposed by Bjork et al., the Dental Aesthetic Index, and the Aesthetic Component of Index of Orthodontic Treatment Need. Data on TMD signs / symptoms and parafunctional behaviour were obtained by means of questionnaire and clinical examination, respectively. Multiple logistic regression models were used for analysis. Twenty-two percent of children and young adolescents had one or more signs of TMD, ranging from 17% in age of 11 years up to 24% in age of 19. There was poor correlation between presence of TMD and orthodontic treatment need. Multiple logistic regression models showed that Class III, crowding and spacing were related to mandibular defl ection on opening. Ectopic eruption was related to TMJ clicking, and severely tipped teeth with reduced mouth opening. Headaches presented a positive relationship with reverse overjet and severe rotations, and tooth wear with crowding, spacing and lateral openbite. Age, female gender and parafunctional habits were related to several TMD signs. Although logistic regression models were statistically signifi cant (p<0.05) malocclusions, parafunctional behaviours, age and gender accounted for less than 20% of the variability in TMD signs / symptoms. TMD signs and symptoms seemed to be poorly related to malocclusions or treatment needs

Structural and phase composition modification of nanocrystalline Nd14Fe79B7 alloy during thermomagnetic measurements

Changes in the microstructure parameters, phase composition and magnetic properties of rapid quenched Nd-rich Nd14Fe79B7 alloy caused by thermomagnetic measurement (TM) were studied using XRD methods of phase analysis, crystallite size and lattice microstrain determination. The observed changes were analyzed between the optimized magnetic state of this alloy and state after TM up to 800oC. Measurement of magnetic properties was carried out on the SQUID magnetometer at ambient temperature. The obtained experimental results show that the investigated alloy in the optimized magnetic state has nearly monophase composition with predominant content of hard magnetic Nd2Fe14B phase (up to 95 mass %) with mean crystallite size below 60 nm. In the state after TM, it was found that the decreased amount of Nd2Fe14B phase (75 mass%), increased amount of soft magnetic phases, predominantly of Fe7Nd5, formation of Nd-rich oxide Nd2O3 phase, as well as grain growth have caused the observed quality loss of hard magnetic properties
