Gas Flow Analysis inside Combustion Chamber of Two Stroke SI Engine

Computational Fluid Dynamics has become an essential tool in the design and development process of IC-engines. Due to increasing computer hardware performances and steady decreasing costs it is to expect that simulation technology becomes an unavoidable tool for the analysis of many technical problems. In present study the flow analysis of the charge in the cylinder of 2 stroke SI Engine using CFD ANSYS fluent is carried out. The variation of pressure, velocity, temperature of charge during its flow from inlet to outlet is studied. The effect of thermal barrier coating (TBC) on the piston crown is analysed. This study may help to optimize the engine performance

Intra-arterial thrombolysis in acute ischemic stroke: A single center experience

Intra-arterial thrombolysis (IAT) is a treatment modality in patients with acute large vessel occlusive ischemic stroke. To our knowledge, this is probably the first reported study of intra-arterial thrombolysis in acute ischemic stroke from India. Of the 17 patients treated who recieved IAT, successful recanalization was achieved in nine patients, Thrombolysis in Myocardial Infarction (TIMI) score of 2 or 3. At 90-day follow-up, eight patients achieved modified Rankin Scale (mRS) score of < 2

Endovascular Stent Graft for Post-traumatic Superficial Femoral Artery Pseudoaneurysms with Arteriovenous Fistula: 6 Months Follow-Up of 2 Cases

Pseudoaneurysms are common vascular abnormalities due to disruption of the vessel wall. Pseudoaneurysm with arteriovenous fistula is a rare presentation. Complications associated with them develop unpredictably and carry a high mortality rate. Traditionally pseudoaneurysms have been treated surgically. However, with the advent of new interventional techniques, management using endovascular approach have gained popularity in treating pseudoaneurysms. Here, we present two cases of large pseudoaneurysms with arteriovenous fistula treated by percutaneous stent graft. Present studies on pseudoaneurysms are all either iatrogenic or secondary to nephrologic dialysis treatment and only few present studies exist describing such large post-traumatic femoral pseudoaneurysms with arteriovenous fistulas were treated successfully by stent grafting through femoral approach, with good patency at 6 months follow up
