A flow injection manifold is proposed for the sequential determination of titratable (total) acidity based on a pseudotitration and of tartaric acid based on the formation of a coloured vanadate complex. The method involves in-line dialysis prior to injection to avoid interference from the sample background absorption in the spectrophotometric detection. The changes in the colour of both reacti...

A multi-input-multi-output (MIMO) sliding mode control scheme was developed with guaranteed stability to simultaneously control air-to-fuel ratio (AFR) and fuel ratios to desired levels under various air flow disturbances by regulating the mass flow rates of engine port-fuel-injection (PFI) and direct injection (DI) systems. The sliding mode control performance was compared with a baseline mult...

We have described a hydro-visco-implantation technique (simultaneous use of sodium hyaluronate and balanced salt solution) for wound-assisted intraocular lens (IOL) implantation and passive removal of ophthalmic viscosurgical device (OVD). In the technique, the capsular bag was filled approximately up to half with OVD, and anterior chamber was formed by bimanual irrigation cannula with continuo...

A dedicated AMS system for biochemical 14C measurements is being built at Center for Accelerator Mass Spectrometry. The system is centered around a National Electrostatics Corporation Model 3SDH-1 1-MV Pelletron accelerator and is designed to accept two ion sources. The LLNL 64-sample Cs-sputter ion source with its zoom lens beam line is attached to one port of the electrostatic switching eleme...

Fluid flow models developed for pipe flows in gasoline port fuel injection system with different number of injectors working under steady state condition was simulated this study using Flow Master Software. Using existing equations, theoretical analysis were computed the same parameters and results obtained each parameter both simulation approach compared accordingly. The that had not shown muc...

• The influence of natural gas direct injection on gasoline port engine is investigated. CO and 2 emissions reduced when R CNG increased. RI decreased by 88.6 % for = 100 CR 12.5 compared to pure gasoline. Addition 25 the knock occurrence significantly. unique properties (NG), including high availability lower cost with other fossil fuels, make it attractive in internal combustion (ICE) applica...
