To develop an efficient and green method to recycling lead slag, a novel strategy fabricate nano-lead dioxide from slag was applied by the hydro-electrometallurgy. In leaching system, optimum condition of time 100 min, 80 °C, stirring rate 500 rpm, liquid/solid ratio 20 1 mol/L methanesulfonic acid resulted in recovery 89% residue obtained without toxicity. The kinetic study revealed that shows...

Polymer composites of polyvinyl chloride, PVC, were loaded up with micro and nano PbO/CuO particles. The added percentage each by mass was 10 wt.%, 20 30 40 plus wt.% mixed composite (20 CuO + PbO). linear attenuation coefficients the investigated measured as a function gamma-ray energies going from 59.53 keV to 1408.01 utilizing standard radioactive point sources. To confirm validity these res...

BACKGROUND Atomoxetine is FDA-approved as a treatment of attention-deficit/hyperactivity disorder (ADHD) in patients aged 6 years to adult. Among pediatric clinical trials of atomoxetine to date, six with a randomized, double-blind, placebo-controlled design were used in this meta-analysis. The purpose of this article is to describe and compare the treatment response and tolerability of atomoxe...

The structural and optical characterization of bulk GeO2-PbO glasses was the goal of this study. In this regard, six different (100-x)GeO2‌-xPbO (15<x<45) glasses were prepared by conventional melt quenching technique between two steel sheets. The produced samples were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) and UV-Vis s...

Resistance to insecticides remains a major problem for the successful control of the horn Xy, Haematobia irritans irritans (L.), one of the most important pests of cattle in many countries including the United States. The organophosphate (OP) insecticide diazinon has been used to control pyrethroid-resistant populations of the horn Xy. There are only a few reported cases of horn Xy resistance t...

Abstract In this work, a novel system composed of non-precious nickel-based metal oxide/reduced graphene oxide nanocomposite (Ni–PbO 2 –GN) is used for electrooxidation ethylene glycol (EG) in 1.0 M NaOH solution and compares its activity with that Ni, Ni–GN, Ni–PbO . The facile electrodeposition technique to prepare the catalysts on glassy carbon (GC) substrates. outcomes electrochemical measu...

The Pseudo-Boolean Optimization (PBO) and Maximum Satisfiability (MaxSAT) problems are natural optimization extensions of Boolean Satisfiability (SAT). In the recent past, different algorithms have been proposed for PBO and for MaxSAT, despite the existence of straightforward mappings from PBO to MaxSAT and viceversa. This papers proposes Weighted Boolean Optimization (WBO), a new unified frame...

Linear Pseudo-Boolean Optimization (PBO) is a widely used modeling framework in Electronic Design Automation (EDA). Due to significant advances in Boolean Satisfiability (SAT), new algorithms for PBO have emerged, which are effective on highly constrained instances. However, these algorithms fail to handle effectively the information provided by the cost function of PBO. This paper addresses th...
