A long-term field-scale demonstration project on the feasibility of using P to immobilize Pb in a Pb-contaminated urban soil was conducted. Phosphate was applied at an average rate of 3040 mg Pykg soil based on a PyPb molar ration of 4.0, with four treatments: T , no P application; T , H PO only; T , 1y2 H PO q1y2 CaH PO ; and T , 0 1 3 4 2 3 4 2 4 3 1y2 H PO q1y2 phosphate rock.

Definition 1.6. Preemption-bound persistent sets. A set T ⊆ T of transitions enabled in a state s = final(S) is preemption-bound persistent in s iff for all nonempty sequences α of transitions from s in AG(Pb,c) such that ∀i ∈ dom(α), αi 6∈ T and for all t ∈ T , 1. Pb(S.t) ≤ Pb(S.α1) 2. if Pb(S.t) < Pb(S.α1), then t↔ last(α) and t↔ next(final(S.α), last(α).tid) 3. if Pb(S.t) = Pb(S.α1), then ex...

Sir, Pustular bacterid (PB) is a pustular disorder of the hands and/or feet. It was first described by Andrews and co-workers (1, 2). There is controversy as to whether PB is a separate disease or is a variant of psoriasis pustulosa palmaris et plantaris (PPP). We describe here a case of PB in a patient with ankylosing spondylitis (AS). This is the first report of PB associated with AS and supp...

The cupferronate ions in the centrosymmetric dinuclear title compound, [Pb(2)(C(6)H(5)N(2)O(2))(4)], O,O'-chelate to the two Pb(II) atoms; two of the four nitroso O atoms are also involved in bridging. The geometries of the five-coordinate Pb(II) atoms in the two independent mol-ecules are Ψ-octa-hedral; if more remote Pb⋯O inter-actions are also considered, the coordination number is increased...

Abelev et al.* (ALICE Collaboration) (Received 14 May 2013; published 5 September 2013) Azimuthally anisotropic distributions of D, Dþ, and D þ mesons were studied in the central rapidity region (jyj< 0:8) in Pb-Pb collisions at a center-of-mass energy ffiffiffiffiffiffiffiffi sNN p 1⁄4 2:76 TeV per nucleon-nucleon collision, with the ALICE detector at the LHC.

A spectroscopic investigation of the complexes formed between the Pb(II) ion and D-penicillamine (H2Pen), a chelating agent used in the treatment of lead poisoning, was carried out on two sets of alkaline aqueous solutions with CPb(II) ≈ 10 and 100 mM, varying the H2Pen/Pb(II) molar ratio (2.0, 3.0, 4.0, 10.0). Ultraviolet-visible (UV-vis) spectra of the 10 mM Pb(II) solutions consistently show...

To identify methylation-mediated silencing of genes in hepatocellular carcinoma (HCC), we surveyed genes induced by treatment with 5-aza-2'-deoxycytidine (5-Aza-CdR) in six human hepatoma cell lines using cDNA microarray analysis and determined the methylation status of 5' CpG islands by bisulfite DNA sequencing or methylation-specific PCR. Fifty genes exhibited a >5-fold induction in response ...

The reaction of lead acetate, benzoic acid and 1,10-phenanthroline (phen) in aqueous solution yielded the title complex, [Pb(C(7)H(5)O(2))(2)(C(12)H(8)N(2))]·C(7)H(6)O(2). In the crystal, the Pb(II) ion is hexa-coordinated by two N atoms from one 1,10-phenanthroline ligand and four O atoms from two chelate benzoate anions. If the second benzoate ligand is treated as one coordination site, the o...

In the crystal structure of the title salt, K(3)[Pb(CH(3)COO)(2)(NCS)](NCS)(2), the [Pb(CH(3)COO)(2)(NCS)](-) anion exists as a covalently bonded entity in which the acetate anions chelate in an anisobidentate manner. The Pb atom shows a distorted ψ-octa-hedral coordination to four acetate O atoms and one isocyanate N atom, with the stereochemically active lone pair occupying one of the six sit...

In this study the origin, behaviour and fate of anthropogenic Pb in sandy roadside soils were assessed by measuring soil characteristics, Pb isotope composition and content. In 1991 and 2003 samples were taken at different depth intervals at approximately 8 and 75 m from two highways in The Netherlands. The Pb isotope composition of the litter layer ((206)Pb/(207)Pb=1.12-1.14) differs from the ...
