purpose: to study the pattern of perfusion of central retinal artery (cra) after 0.1 ml intravitreal injection of bevacizumab to verify the need for any maneuver to decrease the intraocular pressure (iop) including anterior chamber paracentesis (acp) methods: this is a prospective, interventional, noncomparative case series. patients receiving intravitreal injection of bevacizumab for choroidal...

purpose : to evaluate the intraocular pressure (iop) rising effect of anterior versus posterior subtenon injection of triamcinolone in eyes with retinal vein occlusion methods : this prospective nonrandomized study was performed on 57 eyes of 57 patients with macular edema due to retinal vein occlusion. 26 eyes received posterior subtenon injection of 40 mg triamcinolone acetonide [pstt] and 31...

hydraulic conductivity variations around the boreholes in uniformly graded sands for cyclic water injection pressure have been evaluated by laboratory tests. prototype laboratory devices have been designed and constructed for this research. the cell has a capability to model the well, the boundary condition and to measure the hydraulic conductivity. while increasing water injection pressure, hy...

Abstract: In this study, the effect of fuel injection discharge curve and injection pressure simultaneously for upgrading power of heavy duty diesel engine by simulation of combustion process in AVL-Fire software are discussed. Hence, the fuel injection discharge curve was changed from semi-triangular to rectangular which is usual in common rail fuel injection system. Injection pressure with r...

investigations are carried out to evaluate the performance of a low heat rejection (lhr) diesel engine consisting of air gap insulated piston with 3-mm air gap, with superni (an alloy of nickel) crown and air gap insulated liner with superni insert with different operating conditions of crude jatropha oil with varied injection timing and injection pressure.  performance parameters of brake ther...

purpose: to evaluate the effect of intravitreal bevacizumab (ivb) injection on sustained intraocular pressure (iop) methods: this non-randomized prospective study was conducted on 359 eyes of 359 patients in amir almomenin (rasht) and labbafinejad (tehran) hospitals. after history taking and complete ocular examination, iop was measured one week and one day before injection (twice at each sessi...

for technical and economic success of miscible gas injection projects, an accurate laboratory measurement of minimum miscibility pressure (mmp) at reservoir conditions is essential. on the other hand, compositional reservoir simulator is a useful tool in gas injection studies and prediction of mmp. the main goal of this paper is to describe a procedure to generate a three phase sequential type ...

rock selection in modeling and simulation studies is usually based on two techniques; routinely defined rock types and those defined by special core analysis (scal). the challenge in utilizing these two techniques is that they are frequently assumed to be the same, but in practice, static rock-types (routinely defined) are not always representative of dynamic rock-types (scal defined) in the re...
