In the title compound, [Pb(2)(C(7)H(4)FO(2))(4)(H(2)O)(2)](n), one Pb(II) atom is coordinated by seven O atoms and one F atom from five 2-fluoro-benzoate ligands, and the other Pb(II) atom is coordinated by five O atoms from four 2-fluoro-benzoate ligands and three water mol-ecules, resulting in distorted PbO(7)F and PbO(8) polyhedra. The 2-fluoro-benzoate ligands bridge Pb atoms, giving rise t...

OBJECTIVE To examine the associations between treatment/outcome expectations, alliance before and during treatment, and the impact of alliance on symptomatic improvement. METHODS One hundred and fifty-three depressed patients randomized to dynamic supportive-expressive psychotherapy (SET), antidepressant medication (ADM) or placebo (PBO) + clinical management completed ratings of treatment ex...

MAGNETO-OPTICAL current transformers (MOCT) based on the Faraday Effect provide numerous advantages over the conventional transformers. However the commonly used materials in MOCT are crystals that are very expensive and temperature dependence thus will cause many problems for the output signal. Cost efficient diamagnetic PbO-Bi2O3-B2O3 (PBB) glass system is fabricated in this study, for the ai...

The electrooxidation of aqueous solutions containing 5mM of o-, m- and p-cresol at pH 4.0 has been investigated using a flow filter-press reactor with a boron-doped diamond (BDD) under galvanostatic electrolysis. All cresols are degraded at similar rate up to attaining overall mineralization. Comparable treatment of the m-cresol effluent on PbO(2) leads to partial electrochemical incineration. ...

In this study we measured in vitro honey bee enzyme activities in presence of the synergist piperonyl butoxide (PBO) and some new benzodioxole and dihydrobenzofuran derivatives through absorbance and fluorescence spectrophotometric assays, to determine if and to what extent detoxification systems and acetylcholinesterases are affected by these compounds. Both Italian (Italy) and Carniolan (Czec...

Abstract The introduction of carbon nanotubes (CNTs) in the preparation nano-lead oxide (PbO) can effectively solve problem easy agglomeration oxide. This study used concentrated nitric acid and sulfuric mixed (volume ratio 1:3) to oxidize at 90 °C temperature for 0.5 h. Using oxidized CNTs as carriers, Pb(OAc) 2 · 3H O precursor, ammonia a precipitator, PbO/CNTs complexes were prepared by chem...

Unit propagation-based (UP) lower bounds are used in the vast majority of current Max-SAT solvers. However, lower bounds based on UP have seldom been applied in PseudoBoolean Optimization (PBO) algorithms derived from the DPLL procedure for Propositional Satisfiability (SAT). This paper enhances a DPLL-style PBO algorithm with an UP lower bound, and establishes conditions that enable constraint...

Given a set of taxa S and a complete set of quartet topologies Q over S, the problem of determining a phylogeny that satisfies the maximum number of topologies is called the Maximum Quartet Consistency (MQC) problem. The MQC problem is an NP-problem. MQC has been solved both heuristically and exactly. Exact solutions for MQC include Constraint Programming, Answer Set Programming and Pseudo-Bool...

As respostas eletroquímicas de eletrodos de Pb e de Pbs-3.4%Sb em H2SO4 5 M foram examinadas combinando as técnicas de varredura e saltos de potencial. A presença do antimônio evita o bloqueio completo da superfície ativa do eletrodo por cristais de PbSO4 du rante a eletrooxidação, mudando a composição e a estrutura da camada passiva. A eletrooxidação do Sb tem sido interpretada em termos de um...

During the last 5 years JPL has examined a number of concepts 2 for robotically controlled balloons or aerobots. The Venus Geoscience Aerobot (VGA) concept uses reversible fluid altitude control to carry out repeated descents to the surface of Venus. This concept uses frozen water to keep the electronics cool. The balloon must periodically go to high altitude so that the water can be refrozen. ...
