The novel zeolite AgX/CdO NPs composite catalyst has been fabricated under an ultrasound assisted dispersion route and identified by various analysis including FTIR, XRD, FESEM-EDAX, AFM, TEM, and EDAX-Dot mapping. Afterwards, for the first time, the zeolite AgX/CdO NPs composite has been exerted for the effective removal (adsorption and degradation) of fenitrothion (FN, O,O-dimethyl-O-(3-methy...

A model of leucine metabolism in the hind-limb muscles of the milk-fed lamb was developed which permitted simultaneous estimation of the rates of protein synthesis (Ks, days-1), degradation (Kd) and therefore gain (Kg) of muscle in vivo. The conclusions drawn from the model were: the rate of protein synthesis in muscle was related to uptake of leucine; the rate of degradation of protein was rel...

The degradation of poly (vinyl pyrrolidone) (PVP) by means of ultrasound irradiation and itscombination with heterogenous photocatalysis (TiO2 nanoparticles) was investigated. Emphasiswas given on the effect of additive on degradation rate constants. 24 kHz of ultrasoundirradiation was provided by a sonicator, while an ultraviolet source of 30 W was used for UVirradiation. To increase the effic...

Body Bias (BB) control on Silicon On Insulator (SOI) mitigates power consumption on the stand-by mode. However, Negative Bias Temperature Instability (NBTI) changes by BB. We measure the NBTI of ring oscillators on thin buried oxide (BOX) fully-depleted SOI process. NBTI is suppressed and power consumption becomes lower by applying Reverse BB (RBB) because larger threshold voltage decreases car...

In this paper we investigate the existence of travelling wave solutions for a chemotaxis model under the scenarios of zero growth and constant growth rate. We use Lie symmetry analysis to generate generalized travelling wave solutions, a wider class of solutions than that obtained from the standard ansatz. Unlike previous approaches, we allow for diffusivity and signal degradation. We study the...

This paper details the adaptation and implementation of a proposed hierarchical model to the reliability assessment of LED-based luminaires. An Edison base 6 in., compatible can, downlight LED replacement bulb, cooled by active synthetic jets, is used as the test vehicle. Based on the identified degradation mechanisms and the experimentally obtained degradation rate of the cooling device, the r...

Pulp (CP) and ultrafiltered (UF) cactus pear extracts were encapsulated with Capsul (C) by applying a central composite design (CP-C and UF-C systems) by spray-drying. To evaluate the effect of the extract, microparticles obtained under optimal conditions were characterised and stored at 60 °C. Betacyanin and betaxanthin encapsulation efficiency reached values above 98% for both systems studied...

The objective of this study was to determine the effect of povidone. hydroxypropyl methylcellulose, hydroxypropyl cellulose, lactose and magnesium stearate on the stability of quinapril hydrochloride. The applied HPLC method was validated by the following parameters: selectivity, precision, linearity and accuracy. Binary 1:4 mixtures of quinapril hydrochloride and selected excipients were stabl...

The sphingomyelinase (Sphmase) activity degrading sphingomyelin (Sphm) monolayers shows a slow-reaction latency period before exhibiting constant rate catalysis. These two kinetic regions are regulated independently by the lateral surface pressure and by lipids that are biomodulators of cell function such as ceramide, glycosphingolipids, fatty acids, and lysophospholipids. Knowledge of the inte...
