ENHANCING THE TOLERANCE OF FENNEL PLANT TO SALINITY STRESS USING GAMMA RAYS AND LASER AND EVALUATING THE MUTATIONS BY ISSR AND RAPD MARKERS [PDF]
Scientific Journal of Flowers and Ornamental PlantsSalinity causes a decrease in plant growth and productivity, and the problem of salinity increases with the worsening impact of climate change. This work aimed to study the effect of the physical mutants, laser and gamma rays, on the vegetative growth ...

Development of SiC Nanocomposites Using Direct Ink Writing Process
Advanced Engineering Materials, EarlyView.Herein, feedstock inks containing polycarbosilane and various concentrations of SiC nanoparticles (SiCnp) are investigated for fabricating ceramic matrix composites using a DIW 3D printing process. Characterization results from physical measurement, microstructure analysis, and thermal and flexural testing suggested that high‐performance CMC samples ...

On the Detectability of Galactic Dark Matter Annihilation into Monochromatic Gamma-rays
, 2010 Monochromatic gamma-rays are thought to be the smoking gun signal for identifying the dark matter annihilation. However, the flux of monochromatic gamma-rays is usually suppressed by the virtual quantum effects since dark matter should be neutral and ...

Gamma-rays from molecular clouds illuminated by cosmic rays escaping from interacting supernova remnants [PDF]
, 2010 Recently, the gamma-ray telescopes AGILE and Fermi observed several middle-aged supernova remnants (SNRs) interacting with molecular clouds. It is likely that their gamma-rays arise from the decay of neutral pions produced by the inelastic collision ...

Production of Metallic Foam Precursors Using Current‐Activated Pressure‐Assisted Densification
Advanced Engineering Materials, EarlyView.A powder compaction metallurgical method, known as current‐activated pressure‐assisted densification, is applied to enhance the compaction of metal foam precursors. This method improves precursor quality by achieving higher density, lower electrical resistivity, and more uniform pore nucleation in the resulting foams, reducing energy consumption and ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...
