A subconjunctival injection apparatus for administering a pharmacological agent formulation to a subconjunctival compartment of an eye, the apparatus including a jet injector having force generating means that is adapted to generate sufficient force to expel the pharmacological agent formulation from the jet injector and through the conjunctiva. This noise is detected using a probe at the boiler waterwall surface that is connected to a corrosion monitor. A recessed handle structure is also provided, as are alternative embodiments of the internal ramp structure. Across the strip width a cushion of a compressed gas is generated and seals a gap between the ends of the partition facing the strip and the upper and lower strip surfaces. The oxide layer has a thickness of 10 nm or more. The membrane vesicle fission system includes: a membrane vesicle having a lipid bi-layer membrane including a cationic lipid; and a unit which applies, to the membrane vesicle, an anionic material having a hydrophobic group.
