This study investigates the effect of lid motion on the optimal characteristics a thin rectangular fin attached on the hot wall of a square lid-driven cavity with active vertical walls. The optimal fin position is studied for Richardson numbers of 0.1-10. The effect of mounting a rectangular fin with a thermal conductivity of 1 and 1000 on minimization and maximization of heat transfer through ...

Magnetohydrodynamic (MHD) mixed convection flow of Cu–water nanofluid inside a two-sided lid-driven square enclosure with adiabatic horizontal walls and differentially heated sidewalls has been investigated numerically. The effects of moving lids direction, variations of Richardson number, Hartmann number, and volume fraction of nanoparticles on flow and temperature fields have been studied. Th...

The fluid flow and heat transfer in lid-driven enclosures filled with Cu-water nanofluid is numerically investigated. The moving vertical walls of the enclosure  are maintained in a constant temperature, while the horizontal walls are insulated. The hybrid scheme is used to discretize the convection terms and SIMPLER algorithm is adopted to couple the velocity field and pressure in the momentum...

Introduction: Aim of the study was to determine the efficacy of minor lateral tarsorrhaphy in conjunction with levator muscle recession in thyroid ophthalmopathic patients with severe lid retraction in order to correct the temporal flare in these patients Methods: In a before-after clinical trial study, 22 eyelids of 12 patients with severe lid retraction underwent surgery by this method and t...

Low-impact development (LID) practices are gaining popularity as an approach to manage stormwater close to the source. LID practices reduce infrastructure requirements and help maintain hydrologic processes similar to predevelopment conditions. Studies have shown LID practices to be effective in reducing runoff and improving water quality. However, little has been done to aid decision makers in...

In 1916 Pick described a nystagmus-like movement of the upper eyelids in a young woman with a slowly progressive neurological disease characterized by pseudobulbar and cerebellar signs. Her lids were motionless as she looked in the distance but, as she focused on an approaching object, they jerked up and down in rhythmic motions that increased as convergence increased. The lids also elevated in...

objective: to report a case of periocular dirofilariasis. patient and findings: a 27-year-old female referred with history of edema and redness in left eye for two days. on slit-lamp examination, a moving threadlike worm was seen in subconjunctival area. two days later a live filaria worm measuring 12 cm in length was extracted from lower lid subcutaneous tissue. the worm was diagnosed dirofila...
