FINANCIAL AND ACCOUNTING INFORMATION SYSTEMS INTEROPERABILITY

The current economic developments have led to substantial changes in terms of how thefinancial and accounting activities are carried. The business environment can be characterized by awidespread consolidation of companies and their grouping in holding companies. Thus, the focus ison consolidation the financial data, and the integration and interoperability of the financial andaccounting applications and also the integrated information systems have a major significance. Withthe development of the Internet, the architecture of the informatics applications has really beenaffected, this resulted in substantial changes in how the solutions are distributed and accessed aswell. The present paper analyses and provides viable solutions for the use of the technologieswhich are applied in the interoperability of the financial and accounting information systems, in thecontext of economic activity globalization. The dynamism and economic processes development in thenew context have generated important researches in the informatics field which had resulted insimplifying the access way to applications (by simply using a Web browser) and also developing theinterconnecting technologies for the financial and accounting information systems – theirinteroperability represents, in fact, the Keyword.On this economic scenery, the financial and accounting information systems become very importantsolutions to integrate different business applications and also to offer a complete perspective for allthe business.SOA (Service Oriented Architecture), Informational Integrated Systems, XML (eXtended MarkupLanguage), Visual Studio .NET, Web Services

Mechanical Alloying Process Applied for Obtaining a New Biodegradable Mg-xZn-Zr-Ca Alloy

The aim of the present paper is to apply the mechanical alloying process to obtain from powder components a new biodegradable Mg-based alloy powder from the system Mg-xZn-Zr-Ca, with high biomechanical and biochemical performance. Various processing parameters for mechanical alloying have been experimented with the ultimate goal to establish an efficient processing route for the production of small biodegradable parts for the medical domain. It has been observed that for the same milling parameters, the composition of the powders has influenced the powder size and shape. On the other hand, for the same composition, the highest experimented milling speed and time conduct to finer powder particles, almost round-shaped, without pores or various inclusions. The most uniform size has been obtained for the powder sample with 10 wt.%Zn. These powders were finally processed by selective laser melting, an additive manufacturing technology, to obtain a homogeneous experimental sample, without cracking, for future more systematical trials

The Characterization of a Biodegradable Mg Alloy after Powder Bed Fusion with Laser Beam/Metal Processing for Custom Shaped Implants

A new Mg-Zn-Zr-Ca alloy in a powder state, intended to be used for custom shaped implants, was obtained via a mechanical alloying method from pure elemental powder. Further, the obtained powder alloy was processed by a PBF-LB/M (powder bed fusion with laser beam/of metal) procedure to obtain additive manufactured samples for small biodegradable implants. A series of microstructural, mechanical and corrosion analyses were performed. The SEM (scanning electron microscopy) analysis of the powder alloy revealed a good dimensional homogeneity, with a uniform colour, no agglutination and almost rounded particles, suitable for the powder bed fusion procedure. Further, the PBF-LB/M samples revealed a robust and unbreakable morphology, with a suitable porosity (that can reproduce that of cortical bone) and without an undesirable balling effect. The tested Young’s modulus of the PBF-LB/M samples, which was 42 GPa, is close to that of cortical bone, 30 GPa. The corrosion tests that were performed in PBS (Phosphate-buffered saline) solution, with three different pH values, show that the corrosion parameters have a satisfactory evolution comparative to the commercial ZK 60 alloy

Microstructure Evolution during Mechanical Alloying of a Biodegradable Magnesium Alloy

The aim of the present work was to apply a mechanical alloying method to obtain a Mg-10Zn-0.5Zr-0.8Ca powder-alloy with morphological and dimensional characteristics, proper for subsequent selective laser melting (SLM) processing. The mechanical alloying process was applied at different values of the milling time. Thus, the evolution of the main morphological and dimensional characteristics of the experimented powder-alloy could be studied. The conclusion of this study is that mechanical alloying possesses good potential to obtain powder-alloy with almost rounded morphology and fine dimensions, proper for further additive manufacturing procedures such as selective laser melting
