Background: In 1991, Wright described a superior oblique expander procedure for browns syndrome and superior overaction with good results. Originally, this procedure has been performed with silicone band expander. The aim of this study was to report the results of treatment of a series of patients with A-pattern strabismus associated with overacting superior oblique muscle using the fascia lata...

A theoretical investigation has been made on the propagation of ion-acoustic shock waves in a magnetized pair-ion plasma having inertial warm positive and negative ions inertialess super-thermal electrons positrons. The well known Burgers equation derived by employing reductive perturbation method. model supports both structures under consideration It is found that oblique angle (?) enhances ma...

Implanted gold fiducial markers are widely used in radiation therapy to improve targeting accuracy. Recent investigations have revealed that metallic fiducial markers can cause severe perturbations in dose distributions for proton therapy, suggesting smaller markers should be considered. The objective of this study was to estimate the dosimetric impact of small gold markers in patients receivin...

A theoretical investigation associated with obliquely propagating ion-acoustic shock waves (IASHWs) in a three-component magnetized plasma having inertialess non-extensive electrons, inertial warm positive and negative ions has been performed. Burgers equation is derived by employing the reductive perturbation method. Our model supports both structures under consideration of electrons. It found...

The instabilities of thermocapillary liquid layers with two free surfaces are examined by linear stability analysis. surface tension is big enough to keep the non-deformable. effect vertical temperature difference between interfaces (Q) considered. critical parameters preferred modes determined, which depend on Prandtl number (Pr) and Biot (Bi). When Q=0, oblique wave at small Pr streamwise lar...

purpose: to evaluate the effect of botulinum toxin-a (bta) injection into the inferior oblique (io) muscle in releaving the symptoms of superior oblique (so) palsy. methods: the study was conducted on patients who were referred for acquired so palsy with less than 2 years of duration. about 10-20 unit of bta was injected into the belly of the inferior oblique muscle through the inferotemporal q...

In this work, nonlinear variational optimization is used for obtaining minimal seeds the formation of turbulent bands in channel flow. Using together with energy bisection, we have found that threshold spatially patterned turbulence scales $Re^{-8.5}$ $Re>1000$ . The seed, which different to a much smaller domain, characterized by spot-like structure surrounded low-amplitude large-scale quad...

Multivariate multiple linear regression (MMLR), which occurs in a number of practical applications, generalizes traditional least squares (multivariate regression) to right-hand sides. We extend recent MLR analyses sketched MMLR general Schatten p-norms by interpreting the problem as multiplicative perturbation. Our work represents an extension Maher's results on p-norms. derive expressions for...

A theoretical investigation has been carried out on the propagation of non-linear ion-acoustic shock waves (IASHWs) in a magnetized degenerate quantum plasma system composed inertial non-relativistic positively charged light and heavy ions, inertialess non-relativistically or ultra-relativistically electrons positrons. The reductive perturbation method employed to derive Burgers' equation. It o...
