In Chesapeake Bay, Maryland, USA, some of the most contaminated sediments are found in the highly industrialized Baltimore Harbor–Patapsco River area. As part of a comprehensive assessment of sediment quality in this system, sediment toxicity was assessed in 10-d acute tests with the estuarine amphipod Leptocheirus plumulosus. Mean amphipod survival was significantly reduced in 7 of the 25 samp...

This study aimed to investigate the free calcium released from different brands of toothpaste after incorporation with a beta-tricalcium phosphate (?-TCP)/amorphous (ACP) mixed powder and ?-TCP alone. Four were used for experiment: Nano-Bio Activation Toothpaste, Colgate Total Advanced Whitening BORONIA Herbal Whitening, BioMin F. The investigated ACP powders prepared by two-step sintering meth...

Aims: To determine and compare the antimicrobial activity of chewing stick Salvadora persica (Miswak), dental powder toothpastes sold in Umuahia, Abia state Nigeria against selected oral bacteria (Streptococcus spp, Staphylococcus Porphyromona spp Lactobacillus spp). Method: The (Miswak) extracts (ethanol aqueous), two (Agnes nwamma N-sol) five brand (Close-Up, Oral-B, Colgate, MacClean Pepsode...

Colour changes in Gradia Direct™ composite after immersion in tea, coffee, red wine, Coca-Cola, Colgate mouthwash, and distilled water were evaluated using principal component analysis (PCA) and the CIELAB colour coordinates. The reflection spectra of the composites were used as input data for the PCA. The output data (scores and loadings) provided information about the magnitude and origin of ...

This article provides a basic background for the professional who is interested in utilizing event-related potential (ERP) approaches to study language processes but has little background in or knowledge about the technique. First, a brief history of the emergence of this technology is presented, followed by definitions, a theoretical overview, and a practical guide to conducting ERP studies. T...

We introduce a phenomenological investigation of the evolution and large scale distribution of quasars using a modified version of the Field and Colgate gravitational contraction model for proto-galaxies. By studying the distribution of about 7000 quasars in 5 luminosity classes, it seems that, such a model is capable of solving the energy problem and discussing some of the observational proper...
