Electron transfer (ET) processes in DNA are of current interest because of their involvement in oxidative strand cleavage reactions and their relevance to the development of molecular electronics. Two mechanisms have been identified for ET in DNA, a single-step tunneling process and a multistep charge-hopping process. The dynamics of tunneling reactions depend on both the distance between the e...

Objective: Mallampati scoring is the most common examination method for predicting possible intubation problems. The purpose of this study is to investigate the relationship of facial anthropometric measurements with the modified Mallampati score (MMS). Material and Methods: The study population consisted of 153 male and 170 female volunteers (mean ages, 48,9±16,9 and 44,1±15,4 years, respectiv...

BACKGROUND The purpose of this study was to assess and compare nasal symmetry in patients who underwent correction of a complete unilateral cleft lip using the Afroze incision without and with primary septoplasty using a standardized two-dimensional photographic analysis. METHODS A prospective cohort study of 190 consecutive patients with complete unilateral cleft lip and alveolus with cleft ...

Ozone generation using screw-type electrodes with different distance peak to was studied, the view comparing effectiveness of two technologies in improving for high ozone concentration. Current density, heat flux, and distribution electric potential were performed by simulation software Ansys. These simulations indicate that electrode a 2 mm generates higher current result is same as initial as...

The paper solves a long standing problem of finding error bounds for a general perturbation of the Drazin inverse. The bounds are given in terms of the distance between the matrices together with the distance between their eigenprojections. Estimates using the gap between subspaces are also given. Recent results of several authors, including Castro, Koliha, Straškraba, Wang and Wei can be recov...

Diffractive scattering in the presence of a large momentum transfer is an ideal place to study the short distance rapidity gap producing mechanism. Previous studies (experimental and theoretical) in this area have focussed on gaps between jets and on high-t vector meson production. We propose the measurement of double dissociation at high-t. We examine the numerous advantages to studying this m...

Active modulation of the plasmon coupling in homodimers of polyaniline (PANI)-coated Au nanospheres is achieved by changing the proton-doping state of the PANI shell. Such a PANI-enabled modulation of the plasmon coupling in the dimers gives rise to remarkable spectral shifts, which show an exponential dependence on the interparticle gap distance. For the dimer with a 10 nm PANI shell thickness...
