Abstract: Online social networking sites carry a lot of information organized around the people who actually submit it. They rely a lot on the interconnections between the actors of the network and they relate the generated information in terms of connections or ties among those actors. On the other hand, social networks carry a lot of information in real time or almost real time since people “report” information as they see it unfolding before their eyes. We are targeting this information and we try to understand when this information can be related to refer to a single event, which has both a spatial and a temporal dimension. These social sensors can alert us on what is happening in the society when it happens and by aggregating the different reports from people who are on the scene. In order to achieve that we suggest and describe a set of services that can be used for collection of the information, identifying the discussion topics and provide at the end an alert if the discussion qualifies

Abstract: The main aim of this study was the synthesis and characterization of alternative composite inorganic coagulants, resulted from the incorporation of polysilicates and ferric salts in the structure of commonly applied polyaluminum chloride (PACl) in the coagulation–flocculation (C/F) process, in order to increase its efficiency for water and wastewater treatment. The new product is called polyaluminum ferric silicate chloride (PSiFAC) and is synthesized under various experimental conditions and two different preparation methods (copolymerization, or composite polymerization). The major typical properties of the prepared coagulants were examined, i.e. pH, turbidity, conductivity and Al species distribution (e.g. Keggin- Al13), employing the ferron technique. The composition, structure and morphology of the composite coagulants were studied in detail using (among others) the application of FT-IR and SEM techniques. The results show that the new composite materials have high Al13 content (5
