C-shaped configuration in the upper maillary first molar is an extremely rare appearance (0.12%). This case reports management of the tooth with such a configuration as well as depiction of its internal morpholgy and external morphology through spiral computed tomography and dentascan in the contralateral tooth with similar morphology. After careful clinical observation and confirmation through...

Early approaches to understanding intelligence have assumed that intelligence can be studied at the level of algorithms which is why for many years the major tool of artiicial intelligence (AI) researchers has been the computer (this has become known as classical AI). As researchers started to build robots they realized that the hardest issues in the study of intelligence involve perception and...

Euryhaliotrema russellum sp. n. and Euryhaliotrema tenuiaccessorium sp. n. are described from the gills of Lutjanus russellii (Bleeker) and L. argentimaculatus (Forsskål), respectively, in the South China Sea. Euryhaliotrema russellum sp. n. differs from all other members of Euryhaliotrema Kritsky et Boeger, 2002 by its unique male copulatory organ, a straight tube with a bulbous base and witho...

The effects of Russell’s viper venom on blood coagulation, platelets and fibrinolysis were studied after injecting MLD, 1⁄2 MLD and 1:10 MLD intramuscularly in rabbits. RVV was shown to be a strong coagulant in vivo resulting in thrombocytopenia, prolongation of PT, APTT, Thrombin Time and fall of fibrinogen levels. Process of intravascular clotting was very acute in animals receiving MLD and 1...

T bstract his study evaluated the time, occurrence of fracture, nd quality of apical cavity preparation with three ifferent ultrasonic diamond tips: Satelec, Trinity, and a ew type, CVD (chemical vapor deposition), using scaning electron microscopy (SEM) analysis. Thirty human ingle-rooted premolars were selected, submitted to picectomy, and prepared with ultrasonic tips; impresions were then o...

Rhombic cell analysis as outlined in the first paper of the present series is applied to samples of varying depths and liming luminosities of the IRAS/PSCz Catalogue. Numerical indices are introduced to summarize essential information. Because of the discrete nature of the anlaysis and of the space distribution of galaxies, the indices for a given sample must be regarded as each having an irred...
