One-loop contributions to the decay process \(H \to Z*\gamma \to {v_e}{v_e} \gamma \) in standard model are performed in the paper "One-loop contributions to in standard model \(H \to Z*\gamma \to {v_e}{v_e} \gamma \)". The detailed computations are carried out in unitary gauge. In physical results, we present numerical results for partial decay width and its distribution. We find that the partial decay width is given to 0.466 KeV. This result is in the upper bound of the current experimental data at the Large Hadron Collider.

The nasal route for drug administration has the potential for local and systemic delivery of a wide variety of therapeutics. Nasal spray drug delivery has the potential to administer drugs to the bloodstream, avoiding the use of painful needles. While there is great potential, studies in the area are limited and somewhat conflicting. This study aimed to support the improvement of nasal drug delivery through experimental work on a model nasal cavity and through experimental characterisation of nasal spray behaviour. Four different brands of nasal spray were investigated.

The current research is undertaken by performing Computational Fluid Dynamics (CFD) simulations for a 2D aerofoil fitted with a shock control bump at a transonic flow condition. Reynolds-Averaged Navier-Stokes equation coupled with turbulence models is adopted to solve the flowfield. The bump has a conventional geometric feature which consists of a ramp, a crest and a tail, and it has eight variants for which the designed parameters are reasonably specified according to the compressible aerodynamics theory.
