The purpose of this in vitro study was to measure the concentration of hydrogen ions (pH) of calcium hydroxide [(Ca(OH)2] pastes combined with different vehicles over 7 periods of time. The Ca(OH)2 was manipulated with the following vehicles: i: sterile water; ii: iodoform plus sterile water; iii: local anesthetics (Lydocaine 2% with 1: 100,000 epinephrine); iv: polyethyleneglycol; v: glycerin;...

Using 300 nm nanosphere monolayer mask on COOH terminated silane surface as mask, we fabricate a chemical pattern which has polyethyleneglycol (PEG) terminated surface patterned with carboxylic terminated holes. Lysozyme selectively absorbs on the COOH terminated holes forming a hexagonal packed lysozyme monolayer array. The patterned protein islands cover the whole 1x1 cm wafer and have a ring...

Measurement of the double longitudinal spin asymmetry in inclusive jet production in polarized p+p collisions at √ s = 200 GeV Abstract We present preliminary results for the first measurements of the double longitudinal spin asymmetry A LL in inclusive jet production at mid-rapidity in polarized proton-proton collisions at √ s = 200 GeV. The data amount to ∼ 0.5 pb −1 collected at RHIC in 2003...

1. Previous studies have indicated that the permeability of polyethyleneglycol across the human intestine is anomalously high in comparison with the permeability of sugars with similar molecular mass. In consequence it has been proposed that two or more distinct mechanisms must exist for the translocation of these classes of molecule or, alternatively, that the molecular parameter determining r...

We present the results on the mid-rapidity φ meson production in the K + K − decay channel in Au + Au collisions at √ s N N = 200 GeV measured by the PHENIX experiment at RHIC. The spectral shape of the φ resonance, studied at different collision centralities, is consistent with the particle data book. The transverse mass spectra are measured in four centrality bins. The inverse slopes (T), yie...
