Abstract The Boltzmann transport equation is the basic equation for solving the transport of charge carrier (electrons, holes) problems in semiconductor devices. The distribution function has been obtained from the solut...

ABSTRACT In this paper we study the existence, uniqueness and stability solution of fractional nonlinear integro-differential equation, by using the Picard approximation method , and Banach fixed point method. also we ex...

Abstract In a recent paper, Jc Beall and A. J. Cotnoir proposed a bi-modal solution to the fundamental problem of Christology - the problem of reconciling the apparent contradiction implied by Christ’s divine and human...

Abstract Carcass vascular rinsing and chilling involves infusing a chilled isotonic solution (98.5% water and a blend of mono- and di-saccharides and phosphates) into the vasculature immediately upon exsanguination. Prim...

Using quantitative content analysis, we explored how Japanese newspapers framed causal and solution responsibility for depression and whether they attributed more responsibility to individuals or society. The longitudina...

Nonlinear wave dynamics play an essential role in understanding energy localization, pulse transmission, and stability events in a variety of physical systems. Inspired by its importance, we study a fourth-order nonlinea...

We studied in this work a class of nonlinear Volterra integral equations with delay and present a sufficient condition for the bounded solution also we give an illustrative example which support the main result of this p...

One of the most significant and surprising recent developments in nanocrystal studies was the observation of superfluorescence from a system of self-assembled, colloidal perovskite nanocrystals [G. Rainò, M. A. Becker, ...

Abstract A simple, rapid and selective spectrophotometric method for the determination of arginine and lysine was developed. The method is based on the proton transfer reaction of arginine and lysine with alizarin red su...

To address the issues of low solution accuracy, premature convergence, and susceptibility to local optima in the Parrot Optimization (PO) algorithm, a Reinforced Multi-strategy Parrot Optimization (RMPO) algorithm has be...

IntroductionFresh-cut salads are increasingly recognized as possible carriers of foodborne pathogens, including Listeria monocytogenes (L. monocytogenes). As interest in their consumption rises, maintaining their microbi...

Using molecular dynamics experiments, we analyze the association of "Janus" 6-amino-6-deoxy-2O-carboxymethyl-β-cyclodextrins (JCD) in aqueous solutions. In JCD dimers, the free energy associated with the primary-rim-sec...

The scientific literature on the electrochemical conversion of CO2 on silver and silver-based cathodes in aqueous solutions and nonaqueous media has been analyzed. It has been shown that the most problematic issues regar...

Objetivou-se com este trabalho caracterizar espécies diploides, inclusive a espécie modelo Lotus japonicus, e linhas endogâmicas recombinantes do gênero Lotus, quanto à tolerância ao alumínio (Al) tóxico utilizan...

In this investigation, the experimental FT-IR and FT-Raman spectra of cholesterol in the solid phase and in ethanol solution have been combined with the B3LYP/6–311++G** calculations and the scaled quantum mechanical f...

The peculiarities of electronic and crystal structures of Zr1-xVxNiSn (x = 0-0.10) semiconductive solid solution were investigated. To predict Fermi level εF behavior, band gap εg and electrokinetic characteristics of ...

Brain and serum lipid peroxidation was studied in rats treated with vincristine sulphate and different doses of nandrolone decanoate. Thirty rats were distributed into six groups (n=5). The treatments were applied once a...

When at the beginning of 1600, Kepler arrived to work with Tycho Brahe, Longomontanus, Tycho’s principal assistant, who was working with a model for Mars that predicted with remarkable accuracy its longitudes at opposi...

In this paper, a numerical method for solving linear fractional differential equations using Chebyshev wavelets matrices has been presented. Fractional differential equations have received great attention in the recent p...

Abstract Background Myxomatous mitral valve disease (MMVD) is frequently diagnosed in small breed dogs. Pimobendan oral solution has been developed to improve dosing accuracy in small and toy breed dogs. Hypothesis/Objec...

In the work, the additive effect of the content of crystal-forming ions Сd2+ and S2- and the stabilizer L-Cys using the method of mathematical planning of the experiment on the process of formation of CdS/L-Cys nanopart...

The samples of ZrNi1-хVxSn solid solution (x = 0–0.10) based on the ZrNiSn half-Heusler phase (MgAgAs structure type) were synthesized by direct arc-melting with homogenous annealing at 1073 K. The electrokinetic and ...

The photoinduced reaction of 2-iodothiophene in n-heptane, dichloromethane and methanol was studied at room temperature from experiments carried out with degassed solutions. The photoproducts of the reaction were mainly ...

The influence of different parameters (solid–liquid ratio, initial pH, initial Cu concentration and anion type) on the cementation of aqueous copper (Cu) with nanoscale zerovalent iron (nZVI) has been studied. The work...
