Pyrolysis techniques were used to characterize the organic matter contained within the penetrated section and to assess the presence of heavy hydrocarbon shows. The Rock-Eval data indicate a change in organic hydrogen enrichment within the middle Miocene sequence. It appears that the level of organic enrichment may be controlled by sedimentation rate, while the organic hydrogen enrichment, as s...

In the this research, the hydrocarbon generation potential of the Gadvan Formation as a probable source rock was investigated in the central part of the Persian Gulf at the borders of Iran. Type and maturity level of kerogen were investigated in six wells using the results of Rock-Eval pyrolysis and compared with results yielded by the modelling software program known as Pars Basin Modeler (PBM...

The middle Sarvak formation (Cenomanian) is one of the stratigraphic units of the Bangestan group in the south of Iran. This formation is stratigraphically equivalent to the Ahmadi member of Kuwait and Iraq. There is geochemical evidence that indicates this unit has a high level of organic richness and can be a possible source rock in various locations. This study focuses on the organic geochem...

One in nine adults in the United States has chronic kidney disease (CKD). Randomized studies show electronic health (e-health) systems improve health outcomes in chronic disease. This study describes a systematic evaluation of available CKD Web sites. We evaluated Web sites for educating patients with CKD, focusing on three specific design issues: usability, quality, and content. Thirty Web sit...

One of the problems in the use of evolutionary computer systems in artistic tasks is the lack of artificial models of human critics. In this paper, based on the state of the art and on our previous related work, we propose a general architecture for an artificial art critic, and a strategy for the validation of this type of system. The architecture includes two modules: the analyser, which does...

Empirical evaluation methods for visualizations have traditionally focused on assessing the outcome of the visual analytic process as opposed to characterizing how that process unfolds. There are only a handful of methods that can be used to systematically study how people use visualizations, making it difficult for researchers to capture and characterize the subtlety of cognitive and interacti...

Some years ago, the notion of attribute coupled grammars was introduced by Ganzinger and Giegerich 4], together with descrip-tional composition. The latter works essentially at the speciication level, i.e., it produces an attribute grammar which speciies the composition of two attribute coupled grammars. We introduce a new approach to this composition of attribute coupled grammars. This composi...

Dialogue is crucial to evaluation. Through dialogue, people are invited to develop new, shared ways of seeing and acting. From a hermeneutic perspective, dialogue implies consensus, based upon shared meanings and oriented towards reaching agreement. Dialogue also implies disagreement, in the form of a conflict between different, rival stories. The role of the evaluator is to enter into dialogue...
