nanocrystalline zno particles were prepared by a novel sonochemical route from zinc acetate and sodium hydroxide without any requirement of calcination steps at high temperature and without surfactants. variations in several parameters and their effects on the structural (crystal size and morphology) properties of nanoparticles were investigated. characterizations were carried out by x-ray diff...

Nanocrystalline ZnO particles were prepared by a novel sonochemical route from zinc acetate and sodium hydroxide without any requirement of calcination steps at high temperature and without surfactants. Variations in several parameters and their effects on the structural (crystal size and morphology) properties of nanoparticles were investigated. Characterizations were carried out by X-Ray ...

We study a novel property of large rapidity-gap events in deep inelastic scattering at HERA: splitting the pomeron into two jets in the photon-pomeron fusion reaction γIP → qq̄. It gives rise to the diffraction dissociation of virtual photons into the back-to-back jets. We find that at large invariant mass M of two jets, M ≫ Q, the transverse momentum of jets comes from the intrinsic transverse ...

In this paper we consider stochastic differential equations on Banach spaces (not Hilbert). The system is semilinear and the principal operator generating a C0-semigroup is perturbed by a class of bounded linear operators considered as feedback operators from an admissible set. We consider the corresponding family of measure valued functions and present sufficient conditions for weak compactnes...

The dual motor drives fed by a single inverter are purposely designed to reduce size and cost with respect to single motor drives fed by a single inverter. This paper presents the speed responses behavior of Dual Permanent Magnet Synchronous Motor (PMSM) driven by Mean and Differential Torque Control technique. The drive is simulated by using Hysteresis Current Controller. MATLAB/Simulink is ch...

BACKGROUND AND THE PURPOSE OF THE STUDY Different methods have been proposed to modify glassy carbon electrode in order to determine dopamine (DA), as one of the most important neurotransmitters in central nervous systems of mammalian. These methods are time comsuming and in some cases expensive. In this work, a very simple and cheap pretreatment method is developed for the bare glassy carbon e...

1 . I n t r o d u c t i o n Hashing method is a well suited method to achieve state-space exploration for verification of distributed systems. Hashing method is used as searching method to accelerate the retrieval process of a particular state among large state space under exploration. This method enables searching, insertion and suppression operations to be done on average at a constant cost i...

Large symptomatic pleural effusions can be seen in cirrhotic patients with ascites. In this report, two cirrhotic patients with ascites and large pleural effusions were evaluated. To determine the cause of pleural effusion and to understand whether there was a communication of fluid between peritoneal and pleural cavities, 99mTc sulfur colloid peritoneal scintigraphy was used. According to the ...
