Background: Positioning of premature newborns significantly affects their health status. However, the most suitable position remains controversial. The current study aimed to compare the effect of supine and prone positions on oxygen saturation and vital signs in premature newborns. Methods: In this crossover clinical trial, a total of 22 new...
The ionizing radiations are able to make either a permanent or temporarily damage in the electronic circuits. The temporary effects during irradiation can be used to detect the ionizing radiation. In this study a diode in reverse bias has been used to investigate the effects of ionization radiation on semiconductors. The variation of reverse current of diode has been monitored due to interactio...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
In this paper ZnO nanorods and nanodots (with and without a SiO2 buffer layer) were grown on p-Si, forming p–n heterojunctions. The nanorod devices showed no visible electroluminescence (EL) emission but showed rectifying behavior. Covering around 60% of the length of the nanorods with PMMA produced an ideality factor of 3:91 0:11 together with a reverse saturation current of 6:53 4:2 10 8 A. U...
This paper presents the characterization and analysis of a 16.8%-efficient 18 um silicon solar cell on steel substrate. Photoluminescence (PL) is used to monitor the solar cell’s fabrication step by step, and a correlation between PL intensity and implied open circuit voltage is established. PL images yield spatially resolved maps of key electrical parameters such as dark reverse saturation cur...

We present a study of transport in graphene devices on polar insulating substrates by solving the Boltzmann transport equation in the presence of graphene phonon, surface polar phonon, and Coulomb charged impurity scattering. The value of the saturated velocity shows very weak dependence on the carrier density, the nature of the insulating substrate, and the low-field mobility, varied by the ch...
