Monkeys eyes were fixed with glutaraldehyde in vivo at positive intraocular pressure of 35 or 25 mm Hg and compared with eyes fixed without a positive pressure gradient, with the use of light microscopy and transmission and scanning electron microscopy. The entire endothelial lining of the inner wall of Schlemm's canal ballooned or distended toward the external wall of the canal at positive int...

Irrigation canals are generally made through porous soil formations, since the is loose media – a huge amount of canal water lost to conveyance losses. The situation becomes direr when these losses result in non-beneficial Sindh province Pakistan has more than 70% saline groundwater, such areas not only become unusable but also creates management problems. Perhaps cost-effective way address lin...

Conventional aqueous outflow pathway – Comprised of the trabecular meshwork, the juxtacanalicular connective tissue, the endothelial lining of Schlemm’s canal, Schlemm’s canal itself, the collecting channels, and aqueous veins. Flow resistance – The flow resistance (R=DP/Q) of a tissue is the ratio between the pressure drop across that tissue (DP) and the flow rate generated by that pressure dr...

Otitis externa is a common condition of the ear. It is manifested as narrowing of the lumen owing to the edematous swelling of the ear canal lining. Perichondritis may occur independently or as a complication of the otitis externa. We report a case of perichondritis after using a topical ear drop. Changing the medication provides immediate resolution of the condition.

Cytochalasin B at concentrations of 1, 5, 10, 15, 20, or 40 microgram/ml was continuously exchange-perfused into the eyes of nine living Macaca mulatta monkeys while intraocular pressure (IOP) was maintained at 25 mm Hg for 30 min. Pressures were then slowly reduced to 4 mm Hg to permit blood to reflux into Schlemm's canal as a tracer, and the eyes were fixed while maintained at 4 mm Hg IOP. Ti...

Abstract Open channels are one of the most used water conveyance systems for delivering different purposes. Existing models design open mainly assume uniform flow, focus on cross-section sizing, and generally decouple sizing from selection channel alignment profile. In this study, we developed an optimization model a comprehensive transmission channels. The minimizes sum costs earthwork, lining...
