The aim of this study is separation of Fe2O3, TiO2 and V2O5 anomalies in Esfordi 1:100,000 sheet which is located in Bafq district, Central Iran. The analyzed elements of stream sediment samples taken in the area can be classified into 5 groups (factors) by factor analysis. The Concentration–Number (C-N) fractal model was used for delineation of the Fe2O3, TiO2 and V2O5 thresholds. According to...

In this study, solvent extraction method has been utilized for separation of molybdenum and vanadium from nitrate solution by utilizing coupling of acid and solvating extractants (D2EHPA and TBP extractants). The outcomes demonstrated that synergistic solvent extraction improves stability of formatted complexes for transfer to the organic phase. The main parameters such as pH value, concentrati...

An algebraic principle for blind source separation is presented in this paper. This separation principle identi"es a (smaller) set of equations whose solutions can blindly extract non-Gaussian signals. The concept of `Mth-order uncorrelatednessa is introduced and it is proven that for Mth-order uncorrelated source signals, signals with nonzero kth-order cumulant (2(k)M) can always be extracted ...

Blind source separation (BSS) and sound activity detection (SAD) from a sound source mixture with minimum prior information are two major requirements for computational auditory scene analysis that recognizes auditory events in many environments. In daily environments, BSS suffers from many problems such as reverberation, a permutation problem in frequency-domain processing, and uncertainty abo...

A simple and rapid method is described for separation of T-even bacteriophage deoxyribonucleic acid (DNA) from host (Escherichia coli) DNA by hydroxyapatite column chromatography with a shallow gradient of phosphate buffer at neutral pH. By this method, bacteriophage T2, T4, and T6 DNA (but not T5, T7, or lambda DNA) could be separated from host E. coli DNA. It was found that glucosylation of t...

Multilayer packaging, commonly referred to as composite materials, is widely utilized in food storage, distribution, and consumption. The employment of plastic which consists multiple layers polymers, ink, paper, metal, has elicited concerns regarding its detrimental impact on the environment. This article presents an in-depth study delamination process multilayer waste (MLPW) recycling, deemed...

The array factor (sidelobe level, SLL) of a linear array is optimized using modified continuous genetic algorithms in this work. The amplitudes and phases of the currents as well as the separation of the antennas are all taken as variables to be controlled. The results of the design using modified GA versions are compared with other methods. Two design problems were studied using several contin...

By the use of improved isolation and separation methods, it has been shown that the major componentsof the nebramycincomplexproduced by Streptomycestenebrarius are factor 2 (apramycin), factor 4 (6"-O-carbamoylkanamycin B), and factor 5' (6"-O-carbamoyltobramycin). Factor 5, which is identical to kanamycin B, and tobramycin are not produced by Streptomyces tenebrarius but arise from the acid or...
