LOCAL STRUCTURE OF THE CuCu (EDTA) (H2O)2, 2H2O AMORPHOUS COMPLEX : A JOINT MAGNETIC, LAXS, AND MOLECULAR MECHANICS INVESTIGATION
1985
The short range order in the amorphous CuCu (EDTA) (H2O)2, 2H2O is studied by Large Angle X-ray Scattering (LAXS) and molecular mechanics. Three conformations of the complex molecule are shown to be energetically equivalent, two of which are simultaneously present in the amorphous material.
Structure of doped polyaniline - dielectric spectroscopy measurements
1993
The role of doping reagents (residual water and acid anions) in determining the electric properties of a chemically synthesized polyaniline (PANI) was studied using a dielectric spectroscopy method. Dependencies of dielectric losses and susceptibility of PANI as the functions of temperature (-100÷+100°C) and electric field frequency (0.3÷30000 Hz) were examined at it was shown the role of water acts as a doping impurity similar to acid anions. The model is proposed to explain the role of water in terms of adsorption of H 2 O molecules at nitrogen sites of PANI chain and their dissociation
Un questionnaire sur les archives des sciences humaines et sociales en France
2006
Depuis une decennie au moins, plusieurs demarches ponctuelles ont porte l’attention sur l’importance d’une discussion sur les archives des sciences sociales et sur l’urgence de mesures conservatoires pour sauvegarder un patrimoine scientifique menace. Ces initiatives se prolongent aujourd’hui dans une demarche plus large, nationale, qui mobilise les etablissements de recherche et d’enseignement et les Archives nationales. La Maison des sciences de l’homme de Dijon a entrepris l’elaboration d’un inventaire des gisements conserves en France dans le domaine des sciences humaines et sociales en etablissant le questionnaire que nous proposons ici.
Framing Migrant Memories: Lampedusa's Fragmented Archives
2022
The small island of Lampedusa, a key destination of the Central Mediterranean Route connecting Africa to Italy, offers a special observatory on the contemporary trans-Mediterranean odyssey of migrants, although often transformed into a “border spectacle.” Upon landing, migrants are stripped of their belongings, as these are impounded by the authorities. Such an act of dispossession is intended to deprive them of their histories, family ties and cultural identity. Photographer Mario Badagliacca has portrayed a selection of these lost and retrieved items in his work Fragments (2013). Each object reveals expectations, fears, desires, endurance, but cannot tell a full story. They are fragments …
The Saving Narratives of Daša Drndić
2018
The starting point for this paper is the assumption that by obsessive revisiting the events of World War II, the Croatian writer Dasa Drndic attempts to influence indirectly the present. It parallels her narrators’ declarations who—with a great dose of probability—can be simultaneously read as her alter egos. Hence, the article investigates and describes the strategy whose main aim is to retain memory about the past. In Drndic’s texts this function is achieved through the acts of archiving, writing down, and grouping. These acts constitute non-standard ways to enhance the literary text with, for example, whole pages filled with the victims’ names (integrated within the text or acting as a p…
Guardar como. La historia y las fuentes digitales
2011
Este artículo pretende analizar los cambios que vive la historia en el mundo digital. En particular, se centra sobre la digitalización de las fuentes. Por un lado, trata las implicaciones de la conversión digital de antiguos documentos escritos; por otro, se plantea el significado de aquellas otras que llamamos "nacidas digitales". El ensayo repasa algunas de las distintas actitudes de los historiadores ante esas modificaciones y señala que necesitamos atender a sus críticas, pero que también hay otros aspectos que debemos estudiar. En suma, defiende que la historia digital supone un reto sobre el que los historiadores han de reflexionar. This article analyzes the changes that the discipli…
The interaction between social media, knowledge management and service quality: A decision tree analysis
2020
The existing literature fails to identify to which extent the utilization of social media could be relevant for increasing the effectiveness of knowledge management, in respect to overall business operations. In order to shed some light on this area we define three goals. Firstly, we investigate to what extent the different activities of clients on social media (SM), are important to the processes of knowledge management (KM) in companies. Secondly, we examine to what extent KM functions can be relevant in attaining the quality of IT services. Thirdly, we analyze to what extent KM mediates between SM and the quality of IT services, that is, which client activities on SM should be formalised…
Ferroelectric Domain Walls in BaTiO3: Fingerprints in XRPD Diagrams and Quantitative HRTEM Image Analysis
1997
The structure of ferroelectric domain walls in BaTiO3 has been investigated through two complementary approaches, a global one by the fine analysis of X-ray diffraction patterns, the other essentially local via a quantitative image analysis method developed and applied to High Resolution Transmission Electron Microscopy images. These two original approaches converge towards a clear description of 90○ walls which are shown to be a 4–6 nm wide region where the crystallographic discontinuity is accommodated by irregular atomic displacements. The results given here demonstrate that the usual structural theoretical description of walls commonly accepted for energy calculations are far too simpli…
Żagańska kolekcja listów i autografów w Rosyjskim Państwowym Archiwum Akt Dawnych w Moskwie
2021
The Russian State Archives of Historical Records in Moscow (Российский государственный архив древних актор) contains a group No. 1587, which the institutions resource list calls ‘Collection of Autographs Gathered by Princes Żagań.’ The article describes the history of the library of the dukes of Żagań in the 19th century, including the creation of a collection of manuscripts. This collection is of a particular importance as a testimony to the finał years of the Duchy of Courland and Semigalia and the extensive family ties of the princes of Żagań. The collection also includes autographs of important historical figures in Europę, sources concerning the Thirty Years War in Silesia, and relatio…
Short and Medium Range Order in Se1-xTexGlasses
1997
Complementary XAFS measurements (LURE and NSLS) of Se 1 - x Te x glasses have been carried out on both the Se and Te K-edges at low and room temperatures. Using a multi-shell best fit analysis procedure, we have reconstructed the Se and Te local environment: (i) first shell intrachain nearest neighbors (Se-Se 1 , Se-Te 1 , Te-Se 1 ,and Te-Te 1 ); (ii) second shell intrachain (Se-Se 2 and Se-Te 2 ) and interchain next nearest neighbors (Se⇔Se 3 single scattering in the chains Se-Se 1 -Se 3 and Se-Te 1 -Se 3 ). For the first and second coordination shells we suggest that the intrachain chemical order increases with Te content. On the other hand, we propose a model of random distribution of Se…
