The tools implemented for the new Regional Geochemical Database, called GEOBASI, are hereafter presented. The database has permitted the construction of a repository where the geochemical information (compositional and isotopic) has been stored in a structured way so that it can be available for different groups of users (e.g. institutional, public and private companies). The information contained in the database can in fact be downloaded freely and queried to correlate geochemistry to other non compositional variables. The repository has been aimed at promoting the use of the geochemical data already available from previous investigations through a powerful Web-GIS interface. The resulting graphical-numerical tools in such a complex database have been developed to: 1) analyse the spatial variability of the investigated context, 2) highlight the geographic location of data pertaining to classes of values or single cases, 3) compare the results of different analytical methodologies applied to the determination of the same element and/or chemical species, 4) extract the geochemical data related to specific monitoring plans and/or geographical areas, and finally 5) recover information about data below the detection limit to understand their impact on the behaviour of the investigated variable.

Definition Of

In this study the new Regional Geochemical Database (RGDB), called GEOBASI, is presented and illustrated in the framework of a joint collaboration among the three Tuscan universities (Florence, Pisa and Siena), CNR-IGG (Institute of Geosciences and Earth Resources of Pisa), ARPAT (Regional Agency for the Environmental Protection), LAMMA (Environmental Modelling and Monitoring Laboratory for Sustainable Development) Consortium and S.I.R.A. (Territorial and Environmental Informative System of Tuscany). The database has permitted the construction of a repository where the geochemical information (compositional and isotopic) has been stored in a structured way so that it can be available for different groups of users (e.g. institutional, public and private companies). The information contained in the database can in fact be downloaded freely and queried to correlate geochemistry to other non compositional variables. The first phase of the project was aimed at promoting the use of the geochemical data already available from previous investigations through a powerful Web-GIS interface to implement the exploratory statistics graphical-numerical tools used to: 1) analyse the spatial variability of the investigated context, 2) highlight the geographic location of data pertaining to classes of values or single cases, 3) compare the results of different analytical methodologies applied to the determination of the same element and/or chemical species, 4) extract the geochemical data related to specific monitoring plans and/or geographical areas, and finally 5) recover information about data below the detection limit to understand their impact on the behaviour of the investigated variable. Developments of this project will be focused on the definition of rules and standardized methods in a way that external users could also interactively pursue the RGDB. Furthermore, a detailed investigation of the Scarlino-Follonica plain will permit the improvement and test of statistical and geostatistical methods, using open source software (QGIS and R) to support the process of evaluation of the geochemical baseline.

Selection Of

Candidate selection has a direct impact on the quality of a company's human resources department, so it's an essential activity for public and private companies alike. Various ways have been created to assist and make it easier for organizations to select the best candidate, specifically the right people to do specific roles. As a result, the purpose of this study is to propose the use of multi-criteria decision-making techniques in personnel selection. Therefore, for the determination of the weights of the criteria will be employed the SWARA method, whereas, for the ranking of the alternatives, i.e. selection of the best candidate, a CoCoSo method will be applied.

The Subject

This article explores most relevant issues of responsibility of the members of the board of directors in corporations, limited liability companies and joint-stock companies. The object of this research is the relations formed as a result of violations by the members of the board of directors of fiduciary duties imposed upon them. The subject is the norms that regulate responsibility of the members of the oversight council of corporations in civil law, related law enforcement practice, as well as the theoretical provisions of various experts. The main goal of this work consists in determination of relevant problems of the institution of responsibility in form of losses of the members of the board of directors in public and private companies. The scientific novelty lies in the analysis of relevant issues pertinent to responsibility of the members of the board of directors. Detailed analysis is conducted on case law of the courts of superior jurisdiction on the matter. The scientific novelty lies in identification of most urgent problems associated with exercising of authorities of the members of the board of directors and proposal of the mechanisms for improvement of their responsibility in the current legislation, namely with regards to allocation of responsibility for the decisions of higher authorities.  The conclusion is made that the development of the institution of responsibility of the board of directors should correspond with the modern requirements, stimulate economic development, entrepreneurial initiative, allow the subjects of responsibility to predict the consequences of their actions (or inaction), and contribute to efficient fulfillment of their responsibilities.

A sensitive colorimetric determination of fluoride in drinking water has been developed using a polymeric zirconium complex of 5-(2-Carboxyphenylazo)-8-Hydroxyquinoline as fluoride reagents. The method allowed a reliable determination of fluoride in range of (0.0-1.5) mg L-1. The molar absorptivity of the complex formation is 7695 ± 27 L mol-1 cm-1 at 460 nm. The sensitivity, detection limit, quantitation limit, and percentage recovery for 1.0 mg L-1 fluoride for the proposed method were found to be 0.353 ± 0.013 μg mL-1, 0.1 mg L-1, 0.3 mg L-1, and 101.7 ± 4.1, respectively.
