In this study, ZnO nanorods (ZnO-NR) were prepared on n-Si wafer by hydrothermal method. Structural and morphologic properties of nanostructures investigated through XRD SEM The illumination impacts the current-voltage (I-V) measurements Al/ZnO-NR/n-Si diode explored in dark different intensities (20–100 mW/cm2) between ± 1.5 V bias voltage range. Schottky barrier height value had an increasing...

The coupling of electronic degrees freedom in materials to create “hybridized functionalities” is a holy grail modern condensed matter physics that may produce versatile mechanisms control. Correlated electron systems often exhibit coupled with high degree tunability which sometimes lead hybridized functionalities based on external stimuli. However, the and sensitivity stimuli are determined by...

in our country, student transportations’ security and driving accidents statistics for students is one of the major concerns for relevant organizations such as educational organization. in current year, a system, was named sepand, was formed in city taxi driver :::::::union::::::: by educational organization, naja traffic and city taxi driver :::::::union:::::::. in this systems’ plan, basis on...

objective and aims intrauterine devices (iuds) are placed in the uterine cavity with the objective of providing long-term contraception, mainly by preventing fertilization. in this research has been tried to show that method of iud insertion is effective to decrease complications’ incidence . rotating withdrawal technique is presenting, has been using for this purpose. design and setting this h...

We report the use of optical pulse shaping to convert single femtosecond pulses into lower-intensity pulse sequences for excitation of photoconductive dipole antennas, which results in the generation of bursts of tunable narrow-band free-space terahertz radiation. Our experiments demonstrate that the use of such pulse sequences can significantly enhance the spectral amplitude of the narrow-band...

background implant removal is a common procedure in orthopedic surgery which can be associated with many complications such as scar formation, hematoma, nerve injury, infection, and refracture. indications for orthopedic implant removal have declined in recent years. most studies have considered orthopedic hardware removal as an unnecessary procedure in the absence of severe complications such ...

We present a general method for optimizing the configuration of an experimental diagnostic to minimize uncertainty and bias in inferred quantities from data. The relies on Bayesian inference sample posterior using physical model experiment instrument. mean squared error (MSE) samples relative true values obtained high fidelity (HFM) across multiple configurations is used as optimization metric....

craniospinal irradiation plus posterior fossa boost (cs1) is the standard modality of post-operative treatment of patient with medulloblastoma, but considering the technical difficulties and limited facilities, often whole- brain irradiation plus posterior fossa boost (wbi) had been used in our institution until 1991. tust a retrospective study was undertaken to compare the patients treated by ...
