The magnitude optimum (MO) technique provides non-oscillatory closed-loop response for a large class of process models. However, this technique is based on an accurate model which requires precise process identification and extensive computations. In the present lecture, it is shown that there exists a close relation between multiple integrations of the process step response and the MO criterio...

Dispersive liquid liquid microextraction (DLLME) combined with gas chromatography–mass spectrometry (GC–MS) was used for the extraction and determination of 13 polycyclic aromatic hydrocarbons (PAHs) in mineral water samples. In this procedure, the suitable combination of extraction solvent (500 µL chloroform) and disperser solvent (1000 µL acetone) were quickly injected into the water sample (...

Biosolids land application for beneficial reuse applies varying amounts of trace metals to soils. Measuring plant-available or total soil metals is typically performed to ensure environmental protection, but these techniques do not quantify which soil phases play important roles in terms of metal release or attenuation. This study assessed the distribution of Cd, Cr, Cu, Mo, Ni, Pb, and Zn asso...

The research area of information extraction (IE) aims to extract relevant structured information from natural language texts. In addition to the named-entity recognition (NER) task, the identification and classification of relations among entities, namely, the so-called relation extraction (RE) task, is particularly important for many real-world applications. Given the sentence in Figure 1, a R...

The hexaethylcyclohexaarsoxane complexes [{M(CO)3}2{c>’c/o-(C2H 5A sO)6}], M = Cr, Mo, W, 2 4 have been prepared by the reaction o f (C2H 5AsO)n with the respective metal hexacarbonyl in toluene and characterized by their IR and NM R spectroscopic data. For 2 the molec­ ular structure was established by X-ray structural analysis. The 12 atoms o f the As60 6 ring form a flattened cuboctahedron i...

We investigated curvature-enhanced spin-orbit coupling (SOC) and spinterface effect in carbon-based organic spin valves (OSVs) using buckyball C60 and C70 molecules. Since the naturally abundant (12)C has spinless nuclear, the materials have negligible hyperfine interaction (HFI) and the same intrinsic SOC, but different curvature SOC due to their distinct curvatures. We fitted the thickness de...

Cooperation of essential oil into film formation results in active packaging materials, which can improve the quality and freshness foods extend shelf life. In present study, extraction starch was performed. The films were developed through solvent casting method. influence avocado seed orange peel investigated optimized using response surface methodology an artificial neural network on tensile...

It has been suggested that administering vitamin A with the measles vaccine may reduce the vaccine's immunogenicity. This trial examined the effect of supplementing vitamin A during the early months of life on infants' immune responses to tetanus and polio vaccines. Young infants (n = 1085) were enrolled and individually randomized into 1 of 4 groups in a factorial, double-blind, placebo-contro...

photocatalytic decolorization of methyl orange (mo) solution has been studied using phosphotungstic acid (hpa) as photocatalyst. the decolorization reaction of mo solution is photocatalysis. the paper reveals that the optimal loading of photocatalyst for decolorization of mo solution (10 mg/l) is 0.6 g/l. the results show that the photocatalytic decolorization reaction of mo with hpa in a homog...
