Adjusting microwave sensing frequency through aspect ratio variation and bending repetitions in Permalloy ellipses.

The Ferromagnetic Resonance (FMR) phenomenon, marked by the selective absorption of microwave radiation by magnetic materials in the presence of a magnetic field, plays a pivotal role in the development of radar absorbing materials, high speed magnetic storage, and magnetic sensors. This process is integral for technologies requiring precise control over microwave absorption frequencies. We explored how variations in resonance fields can be effectively modulated by adjusting both the shape and stress anisotropies of magnetic materials on a flexible substrate.

Multimedia manuscript. Dual-scope guided (simultaneous thoraco-laparoscopic) transthoracic transdiaphragmatic intraoperative radiofrequency ablation for hepatocellular carcinoma located beneath the diaphragm.

Background: Among treatment modalities for unresectable hepatocellular carcinoma (HCC), radiofrequency ablation (RFA) is getting popular due to low morbidity and its effectiveness. However, when the tumor is located just under the diaphragm, a percutaneous approach for RFA is often impossible because of the difficulty in visualizing the tumor with conventional ultrasonographic examination.

Method: Simultaneous thoraco-laparoscopic transthoracic transdiaphragmatic intraoperative RFA was performed on a 55 year-old male with HCC just beneath the diaphragm as well as laparoscopic RFA for dysplastic nodule near the gallbladder.

Inflammatory pseudotumor of the liver treated by hepatic resection: a case report.

Inflammatory pseudotumor (IPT) of the liver is rare benign tumor. When the diagnosis of IPT is established with biopsy, simple observation or conservative therapy is preferred because of the possibility of regression. But IPT is unresponsive to the conservative treatment, surgical resection should be considered.

The role of splenectomy in patients with hepatocellular carcinoma and secondary hypersplenism.

Hypersplenism, secondary to portal hypertension, is common in hepatocellular carcinoma (HCC) with liver cirrhosis. Hepatic resection in the patient with hypersplenic thrombocytopenia (HSTC) may cause a perioperative bleeding episode and sometimes, liver failure. In order to investigate the effect of concomitant splenectomy in HCC patients with HSTC, clinical parameters are retrospectively reviewed for 18 HCC patients who underwent hepatic resection with or without splenectomy.

Numerical analysis for electrokinetic soil processing enhanced by chemical conditioning of the electrode reservoirs.

A numerical analysis was undertaken for enhanced electrokinetic soil processing. To perform chemical conditioning of the electrode reservoirs, the electrokinetic soil process employed a membrane as a barrier between the electrode reservoirs and the contaminated soil. An alkaline solution was purged in the anode reservoir that was bounded by the membrane.
