investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (lhr) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].the engine had different operating conditions...

A multi-pulse injection strategy for premixed charge compression ignition (PCCI) combustion was investigated in a four-valve, direct-injection diesel engine by a computational fluid dynamics (CFD) simulation using KIVA-3V code coupled with detailed chemistry. The effects of fuel splitting proportion, injection timing, spray angles, and injection velocity were examined. The mixing process and fo...

PURPOSE The development of a method for the sustained elevation of intraocular pressure in experimental glaucoma based on the anterior chamber injection of paramagnetic microbeads. METHODS Unilateral glaucoma was induced in adult male Norwegian Brown rats by the injection of paramagnetic polystyrene microspheres. A handheld 0.45 Tesla magnet was used to draw the beads into the iridocorneal an...

OBJECTIVE To study motor and sensory results of surgery for exotropia following botulinum toxin A injection to correct childhood esotropia. METHODS The medical records of 2445 patients treated with botulinum toxin bimedial injection were retrospectively reviewed to select patients operated on after 1 year of consecutive exotropia. We recorded age at onset of deviation, retinoscopic refractive...

The one dimension computational model of a sequential injection engine, which runs on compressed natural gas (CNG) with spark ignition, is developed for this study, to simulate the performance of gas flow pressure profile, under various speed conditions. The computational model is used to simulate and study of the steady state and transient processes of the intake manifold. The sequential injec...

CASE REPORT A 78-year-old man with phakic eyes underwent photodynamic therapy followed by intravitreal injection of triamcinolone. During the injection a white solution was observed in the anterior chamber. Slit lamp examination revealed white opacities in the inferior anterior chamber angle and neither inflammatory activity nor corneal changes were noticed. DISCUSSION Intravitreal triamcinol...

Injection water temperature is often different from that of the reservoir during injection development in tight reservoir. Temperature change causes fluid properties and oil-water interface properties, which further affects imbibition process. In this paper, a matrix-fracture non-isothermal flow model reservoirs established solved by finite element method based on phase-field method. The ideal ...
