Research ArticleOpen accessIn the abstractGroundwater Dynamics and Quality Assessment in an Agricultural AreaStefano Lo Russo, Adriano Fiorucci, Bartolomeo VignaProblem statement: The analysis of the relationships among the different hydrogeological Units and the assessment of groundwater quality are fundamental to adopt suitable territorial planning measures aimed to reduce the potential groundwater pollution especially in agricultural regions. In this study, the characteristics of groundwater dynamics and the assessment of its quality in the Cuneo Plain (NW Italy) were examined. Approach: … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 29 Sep 2011 · 7,367 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Stringent Authorization using Principles and Policy for Grid ComputingA. R. Jayasudha, T. PurusothamanProblem statement: The current information security mechanisms are insufficient to address authorization issues. The access control models today are mostly static and they are not wellsuited for the service-oriented environments where information access is dynamic in nature. Traditional authorization security techniques do not directly address these concerns as they primarily use access control lists for authorization, where the user whose … …Journal of Computer Science, Vol. 7, Issue 8 · 8 Aug 2011 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeographical Information System Techniques for Evaluation of Groundwater QualityShahram Ashraf, Hossein Afshari, Abdol Ghaffar EbadiProblem Statement: The present paper tries to assess groundwater suitability for irrigation purpose in Damghan plain (5400 ha). Approach: Twenty four water samples were collected from the active wells. Parameters such as Electrical Conductivity (EC), pH, Total Dissolved Solids (TDS), were recorded in the field and major anions and cations (Ca2+, Mg2+, K+, Na+, CO32-, HCO3-, Cl-, SO42- and NO3-) … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 24 Jun 2011 · 8,123 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting Daily Demand in Cash Supply ChainsMichael WagnerProblem statement: Previous studies focused on explaining the long run determinants of currency demand offering limited insight into the short-run determinants and co-variability of daily demand in cash supply chains. Approach: This study contrasted competing techniques of forecasting daily demand in cash supply chains in order to determine the overall performance and the potential of joint forecasting for integrated planning. … …American Journal of Economics and Business Administration, Vol. 2, Issue 4 · 28 Nov 2010 · 7,736 accessesView PDFCite
Research ArticleOpen accessIn the abstractAttributes of Domestic Water Sources in a Rapidly Urbanizing State Capital in a Developing EconomyA. E.
