Gas injection into carbonate formations is one of the most important activities to protect oil reserves that can guarantee a steady production. On-time injection of enough gas can result in the recovery of billions barrels of oil. In addition, it can preserve a huge amount of gas for the next generations. If the reservoir depth is shallow, or the reservoir fluid has a little amount of intermedi...
BACKGROUND The perceived pain on injection site caused by subcutaneous (SC) self-injection may negatively affect acceptance and adherence to treatment in patients with multiple sclerosis (MS). Pain on injection may be caused by inaccurate injection technique, inadequate needle length adjustment, or repeated use of the same injection body area. However, information is lacking concerning the opti...
[1] The evolution of bubbles in a turbulent oceanic boundary layer is simulated using a multi-size multi-gas bubble model coupled with a Large Eddy Simulation model. Bubbles injected by breaking waves are brought into the boundary layer by episodic bubble plumes, and they form near-surface streaks in the convergence zone of Langmuir circulations. The equilibrium bubble distribution decays expon...
Aiming at the melt splashing behavior in smelting process of an oxygen-enriched side-blowing furnace, volume fluid model and realizable k−ε turbulence are coupled simulated. The effects different operating parameters (injection velocity, immersion depth, liquid level) on splash height explored, simulation results verified by water experiments. show that bubbles with residual kinetic energy esca...
OBJECTIVE This study tested the hypothesis that minimally invasive microneedles cause less pain during injection of lidocaine, but induce local anesthesia in humans with the same rapid onset and efficacy as intradermal lidocaine injection using hypodermic needles. METHODS This study was a randomized, single-blinded, within participants, controlled design. Hollow, 500-μm long microneedles were...
Rahman, S., Chen, Y., Zhang, Q. and Lobb, D. 2005. Evaluation methods on manure exposure from liquid manure injection tools. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 47: 6.9 6.16. Laboratory and field studies were conducted to explore evaluation methods on manure exposure (refer as to manure being not covered by soil, but exposed to the air) for liquid manure injection...
