    Data warehouse technology includes a set of concepts and methods that offer the users useful information for decision making. The necessity to build a data warehouse arises from the necessity to improve the quality of information in the organization. The date proceeding from different sources, having a variety of forms - both structured and unstructured, are filtered according to business rules and are integrated in a single large data collection. Using informatics solutions, managers have understood that data stored in operational systems - including databases, are an informational gold mine that must be exploited. Data warehouses have been developed to answer the increasing demands for complex analysis, which could not be properly achieved with operational databases. The present paper emphasizes some of the criteria that information application developers can use in order to choose between a database solution or a data warehouse one.data warehouse, database, database management systems, information systems, data organisation in externe memory, business intelligence

    A Few Implementation Solutions for Business Intelligence

    To succeed in the context of a global and dynamic economic environment, the companies must use all the information they have, as efficiently as possible, in order to gain competitive advantages and to consolidate their position on the market. They have to respond quickly to the changes in the business environment and to adapt themselves to the market’s requirements. To achieve these goals, the companies must use modern informatics technologies for data acquiring, storing, accessing and analyzing. These technologies are to be integrated into innovative solutions, such as Business Intelligence systems, which can help managers to better control the business practices and processes, to improve the company’s performance and to conserve it’s competitive advantages.Business Intelligence, competitive advantage, OLAP, data mining, key performance indicators.

    Data warehouses have been developed to answer the increasing demands of quality information required by the top managers and economic analysts of organizations. Their importance in now a day business area is unanimous recognized, being the foundation for developing business intelligence systems. Data warehouses offer support for decision-making process, allowing complex analyses which cannot be properly achieved from operational systems. This paper presents the ways in which a data warehouse may be developed and the stages of building it.data warehouse, data mart, data integration, database management system, OLAP, data mining

    Inhibition of the β-class carbonic anhydrases from Mycobacterium tuberculosis with carboxylic acids

    The growth of Mycobacterium tuberculosis is strongly inhibited by weak acids although the mechanism by which these compounds act is not completely understood. A series of substituted benzoic acids, nipecotic acid, ortho- and para-coumaric acid, caffeic acid and ferulic acid were investigated as inhibitors of three β-class carbonic anhydrases (CAs, EC 4.2.1.1) from this pathogen, mtCA 1 (Rv1284), mtCA 2 (Rv3588c) and mtCA 3 (Rv3273). All three enzymes were inhibited with efficacies between the submicromolar to the micromolar one, depending on the scaffold present in the carboxylic acid. mtCA 3 was the isoform mostly inhibited by these compounds (K(I)s in the range of 0.11-0.97 µM); followed by mtCA 2 (K(I)s in the range of 0.59-8.10 µM), whereas against mtCA 1, these carboxylic acids showed inhibition constants in the range of 2.25-7.13 µM. This class of relatively underexplored β-CA inhibitors warrant further in vivo studies, as they may have the potential for developing antimycobacterial agents with a diverse mechanism of action compared to the clinically used drugs for which many strains exhibit multi-drug or extensive multi-drug resistance

    Burning mouth syndrome (BMS) - possible pathogenesis related to pain pathways

    Get PDF
    Burning mouth syndrome (BMS) has been admitted relatively recently as a condition/syndrome within oral pathology, bordering various other medical specialties, which may collaborate to determine the diagnosis and especially to achieve therapeutic success. From a clinical point of view, BMS can present itself in 2 forms: the primary/essential form, whose etiopathogenesis is unexplained, justifying the permanent concern as a topic of research at the international level, and the secondary form, in which the causes of the syndrome can be identified and treated/ removed, allowing healing. Particular to the primary form of BMS is the discrepancy between the extent of subjective pain felt by the patient as “burning” and the lack of any objective (clinical) signs in the oral mucosa. In this form of BMS, the pathogenesis of pain can be explained by invoking the role and importance of the field and some favorable factors. In recent years it has been noticed that changes in taste perception and pain tolerance could be possible causes of the “burning” sensation. Thus, the involvement of the field allowed the following hypothesis to be issued, namely that taste is generated mainly at the level of the fungiform lingual papillae

    Myeloperoxidase (MPO) – possible diagnosis biomarker and risk stratification in myocardial inotropism deficit induced by chronic ischemic heart disease

    Get PDF
    The myeloperoxidase levels of 208 patients with ischemic heart disease hospitalized for congestive heart failure were tested at admission, and discharge after 14 days. The calculations for the serum average concentration/lot/date, were made, subsequent, using the values of the tested parameters regarding MPO (admission and discharge) the mean concentration/lot was made, regardless of time of determination. The calculated average values analyses of the three MPO serum parameters were constantly elevated and permanently matched the myocardial contractility deficiency class. The integrated data of the study, allows us to propose the MPO’s circulating concentration as a diagnosis and risk assessment biomarker in the etiology of myocardial ischemia for chronic cardiac failure

    Research and Science Today Journal is a publication founded in 2011 and it is dedicated to the students of all levels (license, master and doctoral) of faculties in the country and abroad. We want to offer the participants the opportunity to present their scientific works in the following areas: Social Sciences, Economic Sciences, Legal Sciences, Humanities, Education Sciences, Engineering, Medicine and Sport. This journal provides students the opportunity to create and / or to improve their abilities to write scientific papers. So each appearance (two appearances per year at which we can add supplements) contains a number of papers written by students, masters and doctoral from the faculties from the country or / and abroad. The journal promotes original studies contributing to the progress of knowledge and it is motivated by the need to address issues of theory and practice in the areas mentioned above. The Journal is a training means of the factors involved in the conceptualization, development, implementation and evaluation , aiming the formation of creative personalities who could be able to adapt through the changing conditions of life. Journal wants to be a forum for debates disciplinaries and interdisciplinaries theoretical topics, to become a research support, to leverage this work at regional, national and international levels. We believe that this gathering will enjoy the support from both parts of the researchers and of the practitioners, and will provide appropriate training sources held professional through the current problems

    Financial Decentralization Reflected in the Revenues and Expenses of Local Budgets in Romania

    No full text
    Decentralization process, due to its inter-sectoral feature, is a very difficult process and requires constant coordination between the actors involved, as well as the undertaking by them, including by the recipients (local public administration authorities), of the measures agreed on. Thus,for this process to be successfully implemented, the transfer of administrative responsibilities must be correlated with that of the financial resources
