Randomized, evaluator-blind, split-face comparison study of single cross-linked versus double cross-linked hyaluronic acid in the treatment of glabellar lines
(BLACKWELL PUBLISHING, 2008)
BACKGROUND At present, various hyaluronic acids are being used to rejuvenate facial skin. There is no comparative study of single cross-linked hyaluronic acid (SCHA) versus double cross-linked hyaluronic acid (DCHA). The ...
Effect of Bleaching on Roughness of Dental Composite Resins
(TAYLOR & FRANCIS LTD, 2008)
This study investigated the effect of three bleaching agents (Whiteness Perfect, Whiteness Super, Whiteness HP) on roughness of three dental resin composites (Admira, Durafill VS, Gradia Direct). Twenty disk-shaped standard ...
Optimization of process parameters for producing graphite concentrate using response surface methodology
(ELSEVIER SCIENCE BV, 2008)
The optimization of process parameters for the production of a graphite concentrate was developed using response surface methodology (RSM). The relationship between the responses, i.e. total carbon grade and recovery, and ...
Ar-40/Ar-39 age and geochemistry of the post-collisional Miocene Yamadag volcanics in the Arapkir area (Malatya Province), eastern Anatolia, Turkey
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The Neogene Yamadag volcanics occupy a vast area between Sivas and Malatya in eastern Anatolia, Turkey. These volcanic rocks are characterized by pyroclastics comprising agglomerates, tuffs and some small outcrops of ...
The influence of priming solutions used in cardiopulmonary bypass on blood viscosity in hypothermic conditions
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
Vessel diameter, flow velocity, temperature, and viscosity are among the factors determining blood flow in vessels. To assess the influence of arterial blood flow on veins in a cardiac operation, the viscosity of blood ...
Determination of Grave Locations in Dedemezari Necropolis (Western Turkey) using Magnetic Field Derivatives
(WILEY, 2008)
The location of the study area for this research of a Middle Bronze Age Necropolis is situated in the west of Turkey near Afyonkarahisar. Magnetic surveying was carried out in two adjacent areas (Areas 4 and 5). Four ...
Adsorptive features of chitosan entrapped in polyacrylamide hydrogel for Pb2+, UO22+, and Th4+
(ELSEVIER SCIENCE BV, 2008)
Chitosan (Ch) was entrapped in polyacrylamide (PAA) by direct polymerization of acrylamide in a suspension of Ch. The adsorptive features of PAA-Ch and Ch were then investigated for pb(2+), UO22+, and Th4+ in view of ...
Effect of external tooth bleaching on dental plaque accumulation and tooth discoloration
(MEDICINA ORAL S L, 2008)
Objectives: Treatment of dental discolorations with external bleaching is becoming very common in dentistry, however, possible irreversible alterations on enamel surface due to bleaching procedures is a topic of discussion. ...
On strong forms of completely irresolute functions
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
In this paper, we introduce new classes of functions which are called completely beta-irresolute functions, perfectly beta-irresolute functions and perfectly irresolute functions. We obtain their characterizations, their ...
Laminarization of internal flows under the combined effect of strong curvature and rotation
(ASME, 2008)
The laminarization phenomenon for the flow under the combined effect of strong curvature and rotation is discussed based on numerical predictions of large-eddy simulation (LES). Initially, the laminarization process is ...
