Background & Objectives: Nanotechnology is one of great important part of technology. Nanoparticles can be used in different applications for industrial, medical, military and personal use. The objectives of this study were preparation of Polystyrene/ZnO nanocomposite films via a simple method and investigation of antibacterial activity of them. Materials and Methods: Polystyrene/ZnO nanopartic...

The high-resolution (2 + 1) resonance-enhanced multiphoton-ionization photoelectron spectroscopy (REMPI-PS) can be obtained by measuring the photoelectron intensity at a given kinetic energy and scanning the single π phase step position. In this paper, we further demonstrate that the high-resolution (2 + 1) REMPI-PS cannot be achieved at any measured position of the kinetic energy by this measu...

A parameterization for the power sums of GL(m|n) type quantum (super)matrix is obtained in terms of it’s spectral values. The work of D.G. is partially supported by the grant ANR-05-BLAN-0029-01. PP and PS are supported by the Russian Foundation for Basic Research, grant No. 08-01-00392-a. D.G. and P.P. would like acknowledge a warm hospitality of the Max-Planck-Institute f ur Mathematik where ...

Objective(s)CpG oligodeoxynucleotides (CpG ODNs) have been shown to have potent immunostimulatory adjuvant activity for a wide range of antigens. Due to susceptibility of phosphodiester CpG ODNs (PO CpG) to nuclease degradation, nuclease-resistant phosphorothioate CpG ODNs (PS CpG) were currently utilized in an in vivo model. In this study, according to some recently reported drawbacks with PS ...

0. Introduction Phonological representations include sequences of featural specifications, pq. Two properties can be observed about such sequences: (i) for a sequence pq to be of significance for the phonology of a language, p must be perceptibly different than q; (ii) to produce a sequence pq, the articulators must start in the configuration for p and then change into the configuration for q. ...

FEW cases of corneal ulceration, proved to be of Ps. pyocyaneus origin, have been described. The case described below is similar to two reported by Ainslie and Smith (1952), and to ten reported by Bignell (1951), all of which were seen in London. The clinical history and appearance of the ulcer were so typical, and the response to Polymyxin B was so prompt that this case is considered worthy of...

In this study we report on the ablation of steel using femtosecond double-pulse trains. Double-pulse trains with pulse-to-pulse separations between 1 ps and 1 ns were used to machine micro-channels in a steel sample. The depths of the laser-ablated channels were measured to characterize the efficiency of the ablation process. Results show that using a double-pulse train with an optimal separati...

OBJECTIVES The purpose of this study is to examine clinical and pathological features, treatment modality approaches in the elderly, especially in patients aged 80 years and older. METHODS From the databases at two educational hospitals during the period from January 1978 and December 2007, medical records of lung cancer patients were retrospectively reviewed. The patient population was divid...
