Phosphate rock (PR) and phosphoric acid (PA) are an effective combination of P sources for immobilizing Pb in contaminated soils. This column experiment examined the effectiveness of different application methods on Pb immobilization in a contaminated soil. Phosphate was applied at a P/Pb molar ratio of 4 with half as PR and half PA. While PR was mixed with the soil or placed as a layer, aqueou...

Purpose To investigate the differences in prostate-specific antigen (PSA) bounce (PB) after high-dose-rate (HDR-BT) or low-dose-rate (LDR-BT) brachytherapy alone in prostate cancer patients. Materials and methods Ninety-four patients with localized prostate cancer (T1-T2cN0), age ranged 50-81 years, were treated with brachytherapy alone between 2008 and 2010. Patients were diagnosed with aden...

The "major" phenobarbital (PB)-induced cytochrome P-450 species present in livers of male Sprague-Dawley rats was resolved into two catalytically active heme-protein fractions on diethylaminoethyl cellulose. The two species, P-450 PB-4 (Mr = 49,000) and P-450 PB-5 (Mr = 51,000), were purified to homogeneity, and their chromatographic, spectral, catalytic, and structural properties were compared...

This tutorial paper examines the relation between the slope of a mean word recognition function and the homogeneity or variability (with respect to recognition) of the individual stimulus items that compose the test materials. This was studied in terms of both the location (Cartesian) and slope of the psychometric functions of the individual words that compose the materials. Word recognition pe...

the synthesis and single-crystal x-ray structure determination of the title compound (dinitrato) (1,4,8,11 -tetra-azaandecane) lead(ii) is described. crystals are monoclinic, p2 /ca= 10.271 (2)?,b= 13.524(4) ?,c= 11.298(6) ?,?=94.68(3),2=4,r,rw, 0.036 and 0.041, respectively. the lead atom is eight-coordinate [pb-n, 2.44 (2) - 2.55 (1)], [pb-0,2.87 (1) - 3.06 (2)].

Has the quark gluon plasma been discovered at the CERN SPS? Experiment NA50 has reported an abrupt decrease in ψ production in Pb+Pb collisions at 158 GeV per nucleon [1]. Specifically, the collaboration presented a striking ‘threshold effect’ in the ψ–to–continuum ratio by plotting it as a function of a calculated quantity, the mean path length of the ψ through the nuclear medium, L, as shown ...

We evaluated the transfer of Pb from shot to meat during the preparation of breasts of quails with 0, 1, 2 or 4 embedded Pb shot. A traditional Spanish recipe was used which utilizes vinegar during cooking to enhance the long-term preservation of the meat. The effect of the acidic conditions generated by the vinegar on Pb transfer was compared with the same recipe when the vinegar was substitut...

We have revealed the fundamental mechanism of specific Cs(+) adsorption into Prussian blue (PB) in order to develop high-performance PB-based Cs(+) adsorbents in the wake of the Fukushima nuclear accident. We compared two types of PB nanoparticles with formulae of Fe(III)4[Fe(II)(CN)6]3·xH2O (x = 10-15) (PB-1) and (NH4)0.70Fe(III)1.10[Fe(II)(CN)6]·1.7H2O (PB-2) with respect to the Cs(+) adsorpt...
