purpose : to compare results of different methods for true corneal power determination and intraocular lens (iol) power calculation formulas in 10 eyes of 7 patients with previous radial keratotomy (rk) with or without astigmatic keratotomy methods : in this case series study, we determined the corneal power of 10 eyes of 7 patients who had undergone rk with or without astigmatic keratotomy wit...
Density Modeling of High-Pressure Mixtures using Cubic and Non-Cubic EoS and an Excess Volume Method
A central issue in the equation of state (EoS) development is to describe accurately fluid density and thus other thermodynamic properties based on it. This study attempts investigate modeling high-pressure mixtures, particularly related reservoir fluids, by cubic non-cubic EoS. large database binary mixtures petroleum fluids was established used compare some typical EoS, including SRK, PR, PC-...
High-pressure phase equilibrium and volumetric properties of highly asymmetric mixtures related to reservoir fluids are critical the development high-pressure high-temperature (HPHT) reservoirs. However, there is a lack relevant data accurate modeling tools. In this work, we prepared pseudo-binary methane (CH4) + stock tank oil (STO) systematically measured their densities at temperatures from ...
In this paper, we describe stochastic Runge–Kutta (SRK) methods with strong order 1.0 for strong solutions of Stratonovich stochastic differential equations (SDEs) which was first introduced by Burrage and Burrage in 1996. In particular, three new SRK methods with strong order 1.0 are constructed. They are an explicit two–stage method, an explicit three–stage method with minimum principal error...
purpose: in the present study we have tried to find the most reliable intraocular lens (iol) power calculation formula in patients with keratoconus (kcn) and cataract. methods: in a prospective case series between october 2010 and march 2012, eligible patients with cataract and kcn underwent phacoemulsification with iol implantation. preoperatively, based on iol master keratometric data iol pow...
Comparison of results of intraocular lens implants with IOL powers obtained by Binkhorst and SRK Linear Regression formulae was done using various models and brands of intraocular lenses. Of 887 pseudophakic patients. 415 patients received IOL's with their powers calculated for planned emmetropia, by means of theoretic formula devised by R.D. Binkhorst and in the remaining 472 eyes the IOL powe...
To investigate the catalytic properties of the Brassica oleracea S-locus receptor kinase (SRK), we have expressed the domain that is homologous to protein kinases as a fusion protein in Escherichia coli. Following in vivo labeling of cultures with 32P-labeled inorganic phosphate, we observed phosphorylation of the fusion protein on serine and threonine, but not on tyrosine. In contrast, labelin...
purpose: to describe the biometric changes and their effect on intraocular lens (iol) power calculation after trabeculectomy and to compare the accuracy of four formulas namely srk/ii, srk/t, holladay and hoffer q for iol power calculation in these patients. methods: thirty-four eyes of 31 glaucoma patients who were scheduled for primary trabeculectomy were enrolled. a non-contact biometry devi...
