Carl Gustav Hempel 's (19051997) classic account of explanation is widely known as the "cover ing-law model. " It includ es two species : the Deductive-Nomological Expla nation and the Probabilistic-Statist ical Explanation . Since its introduction in the semi nal pape r co-authored by Hempel and Paul Oppenheim (1948), the model has been intense ly debated and criticized in the philosophy of sc...

Background: We performed this study in order to investigate the role of chronic endometritis (CE) in unexplained recurrent spontaneous abortion (RSA) and to determine the correlation between hysteroscopic and histologic findings of CE in patients with unexplained RSA. We also tried to find out the relation between CE and primary vs. secondary RSA. Materials and Methods: One hundred and forty-two ...

Two N-donor ligands (L(1) and L(2)) derived from a β-cyclodextrin (βCD) monomer and dimer were employed to mediate the hydrolytic activity and stability of the Ce(IV) ion in aqueous solution. Complexes Ce(IV)-L(1) and Ce(IV)-L(2) were prepared in situ and characterized by means of UV-vis and NMR measurements. Ce(IV)-L(1) catalyzed the hydrolysis of a DNA model, bis(4-nitrophenyl)phosphate (BNPP...

OBJECTIVE We performed contrast-enhanced three-dimensional sonography (CE 3D US) with a perflubutane-based contrast agent to immediately evaluate the completeness of ablation of small hepatocellular carcinoma (HCC) lesions by extracorporeal high-intensity focused ultrasound (HIFU). SUBJECTS AND METHODS Twenty-one HCC lesions were treated by a single ultrasound-guided HIFU ablation session, an...

The integration between technology of remote sensing, information from the data of digital image, and modeling technology for the simulation of water quality will provide easiness during the observation on the quality of water changes on the river surface. For example, Ciliwung River which is contaminated with non-point source pollutant from household wastes, particularly on its downstream. Thi...

RÉSUMÉ. Cet article présente une approche sociale pour la recherche d’information dans les microblogs intégrant diverses sources d’évidence au sein d’un réseau bayésien. Notre contribution consiste à étendre la notion classique de pertinence, basée sur la similarité textuelle, par de nouveaux facteurs tels que l’importance sociale des blogueurs et la magnitude temporelle des microblogs. Dans ce...

PURPOSE The study was conducted to elucidate the detailed expression pattern of angiogenesis-related factors in human ocular surface epithelium. The focus was factors with significantly higher gene expression in corneal epithelium (CE) than in conjunctival epithelium (CJE). METHODS The relative gene expression of 36 angiogenesis-related factors was compared in human CE and CJE, by using the i...
