Method We report a case of 66 years Malay gentleman, diagnosed as large LV aneurysm (7.8 × 4.9 × 8.0 cm) secondary to previous anterior MI, Moderate aortic valve stenosis, Triple vessel coronary disease; underwent LV aneurysmectomy (Ferrazzi procedure) removal of LV thrombus, Sutureless aortic valve replacement (Perceval S), Coronary revascularization and Neo-fenestrated pericardial reconstruct...

In Wireless Sensor Network (WSN), sensor nodes have limitations of energy, so the lifetime of the network is directly proportional to energy factor. All kinds of obstacles exist in the sensing field. Hence the challenge is to determine the obstacle avoiding shortest path with energy efficient clustering. EECP (Energy Efficient Clustering using PEGASIS) presents energy efficient routing by reduc...

Despite many advantages of BrushLess DC motor, torque pulsation is one of the most important disadvantages of it. At first, an optimum primary design of BLDC motor is done using PSO algorithm. Then, other parameters for reducing the torque pulsation are considered by finite element method. It is shown that fractional slot structure has many advantages than conventional one. Both cogging and rip...

Background/Introduction Post-cardiotomy cardiogenic shock (PCCS) occurs in 2-6% of patients undergoing surgical revascularization or valvular surgery. Approximately 0.5-1.5% of patients are refractory to maximal inotropic and intra-aortic balloon counter pulsation (IABP) support. Refractory PCCS leads to rapid multi-organ dysfunction syndrome and is an almost universally fatal clinical state wi...

The hypothesis was tested that pressure and pressure pulsation modulate vascular remodeling. Arterioles ( approximately 200 microm lumen diameter) were dissected from rat cremaster muscle and studied in organoid culture. In the first series, arterioles were kept at a stable pressure level of either 50 or 100 mmHg for 3 days. Both groups showed a progressive increase in myogenic tone during the ...

To determine the extent to which electrophysiologic tests of the afferent visual pathway are affected by vitrectomy, the procedure was performed in 15 eyes of 11 adult Dutch-belted rabbits. An electroretinogram (ERG), visually evoked cortical potential (VECP), and electrically evoked cortical potential (EECP) were obtained preoperatively and sequentially after surgery. For electrical stimulatio...

Transition frequencies of two spherical gas bubbles interacting in an acoustic field are discussed theoretically. In the present study, transition frequency is defined as the frequency of external sound for which the phase difference between a bubble’s pulsation and the external sound is π/2. It is shown by a linear theory that a bubble interacting with a neighboring bubble has three (or fewer)...

The convective heat transfer enhancement in a turbulent boundary layer (TBL) employing pulsed, slot jet crossflow is investigated experimentally. A parametric study on actuation frequencies and duty cycles performed. actuator flush-mounted that injects fluid into well-behaved zero-pressure-gradient TBL over flat plate. heated-thin-foil sensor measures the time-averaged coefficient downstream of...
