Modern quantum theory introduces quantum
structures (decompositions into subsystems) as a new discourse that is not
fully comparable with the classical-physics counterpart. To this end, so-called
Entanglement Relativity appears as a corollary of the universally valid quantum
mechanics that can provide for a deeper and more elaborate description of the
composite quantum systems. In this paper we employ this new concept to describe
the hydrogen atom. We of ...

Zinc
oxide (ZnO) thin films have been deposited using a SILAR (Successive Ionic
Layer Adsorption and Reaction) technique, which is based on the alternate
dipping of substrate in the solution and distilled water. The thin films were
grown on copper, silicon and glass substrates. The precursors for ZnO films
were diluted aqueous solution ZnSO4 complexed with NH3.
The films were investigated by X-ray diffraction, scanning electron micr ...

A polyvinylpyrrolidone (PVP)/Ag
nanocomposite was prepared by reduction of silver nitrate in ethylene-glycol in
the presence of a polymeric protective agent (i.e., poly
(N-vinylpyrrolidone)). The size dependent color variation of this nanocolloid
is a clear indication of the presence of Ag as nanoparticles in the polymer
matrix. The nonlinear optical properties were studied by Z-scan technique in
which a Q-switched Nd: YAG laser with a pulse width ...

Qingshan Thermoelectric Plant located in Wuhan City,
Hubei Province, China, and it uses coal as a fuel. Coal combustion generates
not only gaseous pollutants like SO2 and NOx but also toxic and heavy metals to
the atmosphere. From the environmental point of view, the determination and
speciation of trace toxic and heavy metals released from coal combustion are
very important. In this work, the atomic spectroscopic methods for
determination of so ...

In the current article, the authors
present a new recurrence formula for the determinant of a banded matrix. An algorithm
for inverting general banded matrices is derived.

The question why it is necessary to build the mechanics of
the structured particles, which are the systems of potentially interacting of
the material points, basing on the laws of Newtonian mechanics is discussed. We
will show how to do it without the restrictive hypotheses and assumptions used
in the classical mechanics for construction of the Hamiltonian formalism of the
systems. We will show also how concept of entropy appears in the mechanic ...

Background: Vertical transmission of HIV among women who
have no access to ART is estimated to be 25% - 35% in Africa. Objective: The
aim of the study was to assess the time of MTCT of HIV-1 the efficacy of ART on
prevention of mother-to-child transmission (MTCT) of HIV-1 in two hospitals.
Methods: Prospective cohort study was conducted from November 2011 to May 2012.
A total of 162 participants, 81 mothers (24 non-breastfeeding and 57
breastfee ...

Titania nanopores were fabricated on silicon substrate. Ti thin films (600 nm) were first deposited by radio-frequency (RF) magnetron sputtering at two substrate temperatures and then anodized in glycerol electrolytes containing NH4F. The morphology and structure were identified by means of scanning electron microscopy (SEM), X-ray diffractometry (XRD). The effect of the temperature on the Ti thin films deposited by RF magnetron sputtering and the applied voltage on nanopore morphology were inve...

This study investigated the effects of doping on the etching of SiO 2 and in particular on the etched edge (parts). We have modelized and optimized using experimental data the etching rate of SiO 2. The effects of temperature and oxide nature are factors taken into account in the modelization. The optimization of temperature permits to define the ideal temperature to be used in order to approach anisotropy and to permit repeatability to the etching process in industry. The mo...

Selective methods of thermocatalytic determination of carbon oxide and hydrocarbons in exhaust gases of vehicles are based on measurement of different thermo effects of oxidation of a combustible mixture, obtained from two identical thermosensible elements working at different temperatures are developed. At one temperature there is an oxidation of all analyzed gas mixture, and on another—the mixture without a selectively determined component and by the difference of thermo effects an exact conce...
