the development of green approaches for the biosynthesis of silver nanoparticles (agnps) is of prime significance in the field of nanotechnology research. a fast and eco-friendly protocol for the biosynthesis of extracellular agnps using culture supernatant (cs) from the fungus cunninghamella phaeospora was studied in this work. this cs was proved as a potential new source for the extracellular...

A low-cost spectrum analyzer is presented, based on a commercial software defined radio and an open-source application package. Fundamentals regarding the receiving operation its sensitivity are along with measurements, of two 8 12-bits models. An application, run within GNU Radio, deployed to overcome hardware analog-to-digital converter limitation monitor wide bandwidths. Results shown for di...

Thirteen yr observation data of 4FGL J0824.9+3915 with the Large Area Telescope on board Fermi Gamma Ray Space (Fermi/LAT) are analyzed for revisiting whether 4C +39.23B, a compact steep-spectrum (CSS) source closed to flat-spectrum radio quasar (FSRQ) +39.23A in $\gamma$-ray emitting region J0824.9+3915, is emitter. We find that time-integrated emission overwhelmingly dominated by +39.23A. It ...

We present a method to constrain the injection spectrum of ultrahigh energy cosmic rays (CRs) from supposedly identified extragalactic sources, which can be applied even when only one or two events per source are observed, and is more efficient than a simple fit of the CR energy spectrum including only the contribution of all identified sources. The method is based on the analysis of the probab...

Introduction: Boron neutron capture therapy (BNCT) is recommended to treat the glioblastoma tumor. It is well known that neuron beams are more effective treatment than photon beams to treat hypoxia tumors due to interaction of neutron with nucleus and production of heavy particles such as 7Li and alpha particle. In this study to evaluate the suitability of BNCT for treating of ...
