In a recent paper Schwartz ('74) proposes revised homologies of the deciduous and permanent teeth in living lemuriform primates of the family Indriidae. However, new evidence provided by the deciduous dentition of Avahi suggests that the traditional interpretations are correct, specifically: (1) the lateral teeth in the dental scraper of Indriidae are homologous with the incisors of Lemuriadae ...

Production of aluminum alloy clad strips requires many processes, and a reduction in the number processes has long been demanded. A method to cast directly from molten metal using twin roll caster with copper rolls is proposed this work. Two types casters were designed tested. One was vertical-type tandem other equipped scraper. The casting conducted an oxidizing atmosphere. at speeds higher th...

Identifi cation of novel Hsp65 RFLPs for Mycobacterium leprae. To the Editor: Tongue scraping is advocated as a therapy for managing halitosis and as a technique for preventing dental caries by reducing bacterial counts in the mouth (1). The practice has been in existence for centuries (2). A Cochrane review has concluded that tongue cleaning is marginally and temporarily more effective than us...

While predetermined débitage technologies are recognized beginning with the middle Acheulian, the Middle Paleolithic is usually associated with a sharp increase in their use. A study of scraper-blank technology from three Yabrudian assemblages retrieved from the early part of the Acheulo-Yabrudian complex of Tabun Cave (ca. 415-320 kyr) demonstrates a calculated and preplanned production, even ...

During crystallization the control and effective distribution of heat transfer from the solution to the heat exchanger (HE) plays an important role. Inhomogeneity in temperature on the HEsurface limits the production capacity and increases the tendency of an isolating scale layer formation. To avoid scaling, scraper blades on the HE are commonly used. In a typical axi-symmetric geometry the sca...
