This in vitro study evaluated the biocompatibility and abrasivity of whitening conventional toothpastes. Samples (non-whitening) - Edel White Infant (EWI) toothpastes Whitening (EWW), CAREFORTE (EWC), Colgate Total 12 Ò Professional (C), Oral-B (OB) were dissolved culture medium (0.2 g sample weight per mL). Human gingival fibroblasts (hGF) placed contact with different dilutions media that had...

Recent advances in artificial intelligent techniques embedded into a Field Programmable Gate Array (FPGA) allowed the application of such technologies in real engineering problems (robotic, image and signal processing, control, power electronics, etc.), however, the application of such technologies in the solar energy field is very limited. The embedded intelligent algorithm into FPGA can play ...

1. Remarks on semantics and pragmatics Jacob Mey has contributed most effectively to recognizing the importance of pragmatics. Even a specification of truth conditions (as Carnap's propositions, or in a situational framework) requires the reference of certain items in the sentence to be determined. Thus, pragmatic factors have to be reflected as fundamental and included into the procedure of in...

1 Determining the evolutionary relationship of a set of DNA or protein sequences is a notoriously important problem which becomes particularly difficult in the analysis of large sets of molecular sequence data. Presently used hierarchical clustering methods are not suited for such large scale data analysis due to their preventive algorithmic complexities. Here we discuss a simple approach, rout...

Modern Standard Arabic (MSA) has a wealth of natural language processing (NLP) tools and resources. In comparison, resources for dialectal Arabic (DA), the unstandardized spoken varieties of Arabic, are still lacking. We present Elissa , a machine translation (MT) system from DA to MSA. Elissa (version 1.0) employs a rule-based approach that relies on morphological analysis, morphological trans...
