Following an experimental design, the impact of three factors (grinding pressure, injector pressure and feed rate) on the particulate attributes of micronised powders produced from the different size grades was assessed.
Morpholinos stocks were dissolved at 1 m m in water: 2 or 4 nl of injection solution (0.25% phenol red) containing 125 500 μ m morpholino was injected into fertilized eggs at the one- to two-cell stage using a pressure injector (Pressure System IIe, Toohey Company, Fairfield, NJ, USA).
Power injector pressure-time and flow rate-time graphs in a different patient with IV infiltration during the injection (b) shows rapid drop in pressure and cessation of flow at the time of contrast extravasation.

We compare the ignition effectiveness, in terms of the OH PLIF signal, between a series of test cases with different injector pressures and laser energies.
Current Audi TDI engines use very high fuel and injector pressures (2,000bar, or 29,400psi) to achieve high efficiency, a preference that stemmed from of the company's earlier engines that debuted at Le Mans in 2001.
In this study, several bio-source-fuels like fresh and waste vegetable oil and waste animal fat were tested at different injector pressures (120, 140, 190, 210 bar) in a direct-injection, naturally aspirated, single-cylinder diesel engine with a design injection pressure of 190 bar.
The truck was sent to Westport LD, one of six companies licensed to do conversions for Ford, for installation of C.N.G.-ready fuel injectors, pressure regulator, fuel and coolant lines and other parts.
In Part II of this paper, formulations for describing pressure fluctuations inside the injectors, pressure regulator, and fuel rails are derived and solved simultaneously.
Ignition delay (ID), as well as combustion duration decreased with advanced injection timing, injector opening pressure (IOP) and the compression ratio (CR), while the peak pressure and heat release rate (HRR) increased.
