One-Step Synthesis of Fe-Doped ZnO Thin Films by a Convenient Electrochemical Technique at Room Temperature

This paper reports on the synthesis and characterization of Fe-doped ZnO thin films deposited onto gold coated glass substrates, using electrochemical deposition (ECD) technique at room temperature and different concentrations of Fe. X-ray diffraction (XRD), scanning electron microscopy (SEM), photoluminescence (PL) and optical transmission measurements were used to characterize the films.  ...

A Computer Model for the Movement of Electrically Stimulated Paramecium

In this paper, I will study some parameters that affect the motion behavior of a Paramecium which is exposed to stimulation by electrical pulses. This study is conducted by simulation using a two – segment electrophysiological model computer program. The goal of the simulation program is to find the relation between the intraciliary calcium concentration, [Ca2+]i and the electric pulses’ amplitude applied to a free swimming Paramecium, as well as to explore the relationship between the electric pulse amplitude and the ciliary reversal time. ...

Particle Size Distributions Inside a University Office in Amman, Jordan

We studied the number based particle size distribution (diameter 0.3–10 µm with high time-resolution) inside an office (naturally ventilated) at a university building in Jordan during two weeks (18.09.2013 – 01.10.2013). We analyzed and investigated the particle number and mass concentrations, their differences between workdays and weekends and the effect of tobacco smoke and worker activities inside the office. ....

Structural and Mössbauer Studies of Ball Milled Co-Zn Y-type Hexaferrites

Y-type hexaferrite samples Ba2ZnxCo2-xFe12O22 with x = 0, 1 and 2 were prepared from precursors synthesized by the citrate sol-gel auto combustion method. The powders were sintered at 1100° C for four hours. X-ray diffraction, scanning electron microscopy and Mössbauer spectroscopy were used to investigate the effect of ball milling on the structure, microstructure and on the hyperfine parameters. ...

Some General Properties of the Emitted Fragments in Interactions at 4.5GeV per Nucleon

An attempt has been made to investigate some features of nuclear fragments produced in high energy heavy ion collisions. Emission characteristics such, as the nuclear cross- section and the normalized moments of relativistic charged particles and their dependence on the projectile and target mass and the projectile energy, produced in (4.5AGeV/c)silicon – emulsion interactions, are investigated. Results obtained in the present work are compared with those reported by other researchers.

Features of the Forward-Backward Particles in the Collisions of Carbon with Nuclear Emulsion at High Energy

Experimental data on relativistic (shower) and fast (grey) hadrons emitted in the forward and backward hemispheres        ( QUOTE  , (FHS,BHS), in the collision of  QUOTE  beam with emulsion nuclei at 4.5AGeV/c  QUOTE  QUOTE    are presented and analyzed. The correlations between multiplicities of shower particles are also investigated. ...
