The nose is a midline structure - cartilage from both sides of the face form the framework of the nose. Parts of the maxilla bones and palatine bone create the bony structure of the base of the nasal canal. The vomer, ethmoid, and nasal bone make up the roof and walls of the nose and the bony framework. The external appearance of the nose is formed predominately from cartilage. Since the nose lays in the middle of the face, it has an extensive blood supply. The blood that perfuses the nose is mainly from branches of the facial artery. The branches of the facial artery and the superior labial artery perfuse the nose via the septal branches, the angular artery, the external nasal artery, the dorsal nasal artery, and the lateral nasal artery. The nose also receives blood from arterial anastomoses adjacent to the nose. The lateral nasal artery predominately perfuses the structures that make the external appearan...

We have synthesized Silica from "petung"bamboo leaf ash as SiO2 source. This step used sol gel methode. SiO2 were characterized by Fourier Transform Infra Red (FTIR) to investigated the stucture andX-Ray Diffaction to know about structure and crystallinity. FTIR spectra show peak at 617,22 cm-1 area that spesific for Si-H bond, peak at 786,96 cm-1 and 1095,57 cm-1 area specific for Si-O-Si bonds. Difractogram of SiO2 show that there are peak at 2θ 21,99; 31,67 and 38,88 were specific for SiO2 that calcinated at 800 o C, while for SiO2 that calcinated at 400 o C there were no peak at 2θ 31,67 dan 38,88. That peaks not shown may be because low crystallinity of SiO2 that calcinated at 400 o C. Calcination temperature greatly affects the crystallinity of SiO2.
