to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...

Polyphosphate is a phosphate polymer which is effective for stain removal and prevention of stain deposition. Ultraphosphate belongs to the polyphosphate group and has a highly branched mesh-like structure. To evaluate stain control ability of ultraphosphate, we used HAP powder, glass-ionomer cement and detached human teeth for models of in vitro stain control experiments. When using HAP powder...

PURPOSE The innervation of the scleral spur region was investigated to learn whether mechano-receptors are present in this region. METHODS Serial tangential sections and whole-mount preparations of the scleral spur region of 18 human eyes of different ages were investigated with electronmicroscopic and immunohistochemical methods.
