A complete lattice L is constructively completely distributive CCD L if the sup map de ned on down closed subobjects has a left adjoint It was known that in boolean toposes CCD L is equivalent to CCD L We show here that the latter property for all L su ciently for characterizes boolean toposes Research partially supported by grants from NSERC Canada Diagrams typeset using catmac Introduction Th...

Experimental testing of deformed rebar anchors (DRAs) has not been performed extensively, so there is limited test data to understand their failure behavior. This study aims expand upon these tests and the behavior anchors, when loaded in tension. Analytical benchmark models were created using available a parametric was performed. Anchor diameter, spacing, embedment, number varied for total 49 ...

Radial or pincushion distortion problem of the wide angle charge-coupled device (CCD) camera is an important issue in the image calibration in case of close-up photography of real scene. We designed the auto-extraction method of the warping points in the calibration algorithm of the image acquired by the wide angle CCD camera. Proposed method extracts the distortion point by the wide angle CCD ...

The recent advances in ocular drug delivery have been successful surpassing conventional therapy, owing to its considerable limitations. This study aims develop and optimize in-situ liposomal system design once-daily liquid preparation treat Keratoconjunctivitis sicca. Liposomes of Hyaluronic acid were prepared using soya lecithin by a thin film hydration method. Eight trial formulations made k...
