We discuss the existence and non-existence of constant scalar curvature, as well extremal, Sasaki metrics. prove that natural Sasaki–Boothby–Wang manifold over admissible projective bundles local products non-negative CSC Kähler metrics, described in [3], always has a curvature (CSC) metric its Sasaki-Reeb cone. Moreover, we give examples show extremal Sasaki–Reeb cone, defined set vector field...

this study lias been carried out on 70 patients who were admitted to s'tna hospital emergency department with a clinical diagnosis of acute abdominal pain and underewent appendectomy. 70 pathologic specimens (appendices) were studied macroscopicaky and microscopically; 46 cases were consequently diagnosed as appendicitis and 24 as non-appendicitis. all 70 specimens were examined carefully for t...
