A simple clustering technique is presented in this paper to simplify the dynamic system via reducing the order of its transfer function. The reduced denominator polynomial of thesimplified model is determined by a simple pole clustering technique and the numerator coefficients are obtained byusing improved Pade approximations method. The dominant pole of a cluster may be inside or outside of th...

Despite marvelous advances in repair for acute type A aortic dissection over past decades, it remains challenging to repair the aortic root when aortic dissection extended to the sinuses causes the fragile root because of its thinner layers, which are susceptible to suture trauma. Here, we describe a modified Florida sleeve technique to strengthen the weakened aortic root. After mobilization of...

Using the tumescent technique, liposuction can remove large volumes of fat with minimal blood loss. A maximal safe dosage of dilute lidocaine using the tumescent technique is estimated to be 35 mg/kg. The slow infiltration of a local anesthetic solution of lidocaine and epinephrine minimizes the rate of systemic absorption and reduces the potential for toxicity. Dilution of lidocaine (0.05% of ...

This study investigated the oxidation of ascorbic acid (Vitamin C) using a platinum nanoparticle electrode coated with an iodine monolayer, called a modified electrode. The electrode were grown using the cyclic voltammetry technique and the electrochemical measurements were taken using the cyclic voltammetry and chronoamperometric technique. In the case of platinum nanoparticle electrode modifi...
