Colloidal semiconductor nanocrystals have attracted continuous worldwide interest over the last three decades owing to their remarkable and unique size- and shape-, dependent properties. The colloidal nature of these nanomaterials allows one to take full advantage of nanoscale effects to tailor their optoelectronic and physical-chemical properties, yielding materials that combine size-, shape-,...

the revival of chalcolithic sites have a particular importance in tracing the settlement patterns of the region, in the aegis of special biological features and replacing in environmental elements. by depicting the special features, the characteristics of plain of hamedan and its strength in northern plain (kaboodarhang) must be hinted. this plain is determined as a joint fund between central z...

Combining logics has become a rapidly expanding enterprise that is inspired mainly by concerns about modu larity and the wish to join together tailored made logical tools into more powerful but still manageable ones A natural question is whether it o ers anything new over and above existing standard languages By analysing a number of applications where combined logics arise we argue that combin...

Visualizing a complex network is computationally intensive process and depends heavily on the number of components in the network. One way to solve this problem is not to render the network in real time. PRE-render Content Using Tiles (PRECUT) is a process to convert any complex network into a pre-rendered network. Tiles are generated from pre-rendered images at different zoom levels, and navig...

The findings of the COMBINE Study have recently been published (Anton et al 2006). The COMBINE Study is a major, multisite RCT of acamprosate and naltrexone in conjunction with behavioural treatment. As such this study has the potential to significantly influence treatment of alcohol dependence. This brief critical appraisal of the COMBINE Study has been prepared to assess its implications in t...

The COMBINE Project analyses opportunities and problems provided by the Traffic Management System (TMS) when using the moving block signalling system for railway operation. The site chosen for verification is the Breda triangle in the Dutch part of the high-speed line Paris-Brussels-Amsterdam. Currently, there are no applications of moving block on main-line railways, apart from several test in...

The primary goal of the OPTIMA project is to optimize HVAC systems (heating, ventilation and air conditioning systems) and building structures with respect to energy consumption. Presently the focus is developing an integrated computerized system for simulation purposes. A central data repository defined by a data model provides data persistency. The existing data models developed in ATLAS [1,2...
