light is one of the many wonders in the architecture iranian houses. it is a major tool for space creation anddesign. an important consideration in the iranian architecture, which takes a functional and conceptual approach to the extensive subject of light, has been that light should create a beautiful and spiritual space in addition to being functional. the light used in a house should be plea...

The Advanced Photon Source (APS) design incorporated a positron accumulator ring (PAR) as part of the injector chain. In order to increase reliability and accommodate other uses of the injector, APS will run with electrons, eliminating the need for the PAR, provided another method of eliminating rf bucket “pollution” in the APS is found. Satellite bunches captured from an up to 30-ns-long beam ...

In this study, we developed 20 polymorphic microsatellite markers for the Korean black scraper, Thamnaconus modestus (Günther, 1877), Monacanthidae, and used them to compare allelic variation between wild and hatchery populations in Korea. All loci were readily amplified and demonstrated allelic variability, with the number of alleles ranging from 5-35 in the wild population and 5-22 in the far...

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 ...

Two new Xiphocentronidae species are described, Machairocentron falciforme sp. nov. and Xiphocentron (Antillotrichia) sclerothrix sp. nov. Illustrations of the males, females and pupae are presented. Adults were obtained through the emergence of pupae in the laboratory and from collections in traps suspended 1 m above the water in four streams in Presidente Figueiredo, Manaus and Barcelos munic...

The use of a two stage crystal collimation system in the RHIC yellow ring is examined. The system includes a copper beam scraper and a bent silicon crystal. While scrapers were installed in both of the RHIC rings before the year 2000 run, the crystal is installed for the 2001 run in one ring only, forming a two stage collimation system there. We present simulations of the expected channeling th...

Two types of high-speed twin-roll casters and a single-roll caster equipped with scraper were proposed. One the is vertical-type caster, other an unequal-diameter caster. The can cast strip at speeds up to 120 m/min. casts 60 superior point conveyance strip. A without center-line segregation 40 use copper alloy roll non-use parting material enable casting. Since loads these are smaller than 0.1...
