A novel ISM band reflector type applicator design for microwave ablation systems.

In this paper, a radiation performance improved novel applicator is proposed which is called as reflector type microwave applicator as a part of microwave ablation (MWA) system operating at 2.45 GHz with experimentally measured bandwidth of 300 MHz in Industrial Scientific Medical (ISM) band for the local extermination of tumor with highly localized microwave power. The design principle of MW applicator is based on the structural formation of coaxial transmission line fed dielectric loaded with the metallic circular reflector for the near field energy concentration inside the tumorous tissue.

Formability of Ultrasonically Additive Manufactured Ti-Al Thin Foil Laminates.

This study investigates the effect of strain rates and temperatures on the mechanical behavior of ultrasonically consolidated Titanium-Aluminum thin foils to understand and characterize their formability. To this goal, laminated composite samples with a distinct number of layers were bonded using ultrasonic consolidation. Then, tensile and biaxial hydraulic bulge tests at different strain rates and temperature conditions were conducted.

Cardiac complications in Behçet's disease.

Behçet's disease (BD) is a multisystem disease of unknown aetiology characterized by chronic relapsing oro-genital ulcers, uveitis, and systemic involvement including articular, gastrointestinal, cardiopulmonary, neurologic and vascular pathology. Vascular involvement is observed in 30% of cases. Although the pathogenic mechanisms underlying the thrombotic disposition in BD are not well known, prothrombin (PT) gene mutations may be one factor that contributes to the development of vascular involvement in this disorder.
