Evaluation of Moonpool Effects on Hydrodynamic Resistance of a Supply Vessel, Using Experimental and Numerical Methods

Moonpool is an opening in the floor or base of a hull ship which can be used to lower tools and vehicles into the sea in a protected area. In this paper, the effect of a rectangular cross section moonpool on the resistance force of a supply vessel was investigated both by experimental and numerical methods. For both methods a 1:37.2 scale of Caspian3 surface vessel was used. Experiments were ca...

Evaluation of the Effects of Injection Velocity and Different Gel Concentrations on Nanoparticles in Hyperthermia Therapy

Background and objective: In magnetic fluid hyperthermia therapy, controlling temperature elevation and optimizing heat generation is an immense challenge in practice. The resultant heating configuration by magnetic fluid in the tumor is closely related to the dispersion of particles, frequency and intensity of magnetic field, and biological tissue properties.Methods: In this study, to solve he...

Evaluation of immunopathologic effects of aqueous extract of Echinacea purpurea in mice after experimental challenge with Pasteurella multocida serotype A

In order to assess the immunopathological effects of aqueous Echinacea purpurea extract (EPE) on mice experimentally challenged with Pasteurella multocida serotype A, forty female BALB/c mice were randomly divided into four groups. The groups included a control group (received sterile distilled water 2 times/week for 2 weeks, intraperitoneally and then 100 μl sterile saline intranasally), a PMA...
