Persulfate and sulfate radicals with strong standard oxidation potentials and relatively low cost be used in advanced oxidation processes. The object of this study was to evaluate the performance of a sulfate radical-based advanced oxidation process with surfactant-modified zeolite for treatment...

This paper proposes a novel method relating to the recycling of waste lead ash originated from procedure of lead alloy production. The spent lead ash was first disposed by acetic acid leaching system, where lead ash structure wrapping impurities would be destroyed. The synthesis of lead oxide pr...

Increasing global lead consumption has been mainly supported by the acid battery manufacturing industry. As the lead demand will continue to grow, to provide the necessary lead will require an efficient approach to recycling lead acid batteries. In this paper was performed a mathematical modelin...

Iron(III) chloride deoxygenated alkaline aqueous colloidal solutions in the presence of 2-propanol and dextran sulfate were γ-irradiated with doses of 36 and 130 kGy. The dose rate was ∼31 kGy h−1. The samples isolated by washing with water mainly consisted of γ-FeOOH (lepidocrocite), δ-FeOO...

In this study, ultra-fine lead oxide, lead carbonate and lead hydroxyl carbonate particles were synthesized and modified by a surface sulphidization route to form a sulphide surface layer which is interesting in electronic and optoelectronic device as well as vacuum tribological applications. Al...

Two new hadronic cross sections measured by the BaBar experiment are presented: e+e−→π+π−π0π0 and e+e−→π+π−η. For both channels, the contribution to the anomalous magnetic moment of the muon is calculated.

Ethnopharmacological relevanceFruits of Apium graveolens (celery) are used traditionally in Persian and European medicine for the treatment of uncomplicated urinary tract infections.Aim of the study: The study aimed at identifying potential antiadhesive compounds from celery extracts to provide ...

Chondroitin sulfate E (CSE) markedly enhanced plasminogen activation by tissue plasminogen activators (t-PAs) and urinary plasminogen activator (u-PA) in vitro; in the presence of 10 μg/ml of CSE, the potentiation factors of single chain of t-PA, two chain of t-PA and u-PA were 400, 140 and 130...

We introduce a new method for selecting exclusive semileptonic charmless B-decays in the presence of a large background. The method can be applied to charged and neutral B-mesons decaying into any exclusive semileptonic final state. The method is designed for high luminosity e+e− colliders opera...

We present a short review of our (e,2e) measurements of electrons emitted after 2p inner-shell excitation of argon. The LMM Auger electrons are measured in coincidence with the scattered electrons, producing the considered excited state. Particularly the 2p3/2→4s3/2 and the dipole forbidden 2p3...

The last enzyme (LytB) of the methylerythritol phosphate pathway for isoprenoid biosynthesis catalyzes the reduction of (E)-4-hydroxy-3-methylbut-2-enyl diphosphate into isopentenyl diphosphate and dimethylallyl diphosphate. This enzyme possesses a dioxygen-sensitive [4Fe–4S] cluster. This pros...

As part of a broad-based SAR investigation of E-resveratrol (strong sirtuin activator and antineoplastic) and the anticancer vascular-targeting combretastatin-type stilbenes, a series of twenty-three β-E-nitrostyrenes was synthesized in order to evaluate potential antineoplastic, antitubulin, a...

Endonuclease III, a highly conserved enzyme initiating the base excision repair of oxidized DNA bases, hosts a [4Fe-4S] cluster. Unlike many other iron–sulfur clusters, the [4Fe-4S] cluster of endonuclease III is stable and resistant to both oxidation and reduction. Here we show that the [4Fe-4...

Citrate, sulphate, oxalate, chromate, carbonate, fluoride, acetate, formate, iodate, bicarbonate, bromate, chloride, nitrite, chlorate, bromide, nitrate, iodide, perchlorate and thiocyanate (each with sodium as counter-ion) were applied to a column of Sephadex G-15, and elution was carried out w...

When a sample solution containing sodium-22-labelled sodium chloride and carrier-free phosphorus-32-labelled phosphoric acid was eluted from a Sephadex G-15 column with either 0.025 M sodium or potassium phosphate buffer (pH 7.0), the labelled phosphate ion was eluted earlier than the sodium-22....

When a mixed solution of 0.72 M potassium and sodium chloride was eluted from a Sephadex G-15 column with 0.025 M sodium phosphate buffer (pH 7.0), the elution profiles of ions showed that the potassium and chloride ion pair from the sample and the sodium and chloride ion pair produced by ion-ex...

Density-gradients centrifugation (DGC) and filtration columns (FC) are used to separate deformed or dead sperm, debris, and other cells that may negatively affect the fertilizing capacity of sperm in fresh, chilled and frozen/thawed semen. The present study was conducted to evaluate the suitabil...

There is good evidence that, in Sephadex gels, oligosaccharide series how (positive) linear free energy relations with respect to the degree of polymerisation. The distribution coefficients of disaccharides are thus a measure of the differences between the polyglucan series to which they belong....

The gel-permeation characteristics of selected sugars and sugar derivatives were determined on a column of Sephadex G-15. The following observations were made: (1) the Sephadex G-15 column does not distinguish between enantiomeric saccharides, (2) a decrease in Rg, value is observed on going fro...

When a mixed solution of sodium or potassium dihydrogenphosphate and disodium or dipotassium hydrogenphosphate was eluted from a Sephadex G-15 column with either a sodium or potassium chloride solution, the elution profiles of ions showed that the hydrogenphosphate ion was eluted more rapidly th...
