In this paper, the sectional curvature of non-degenerate tangent sections of time-like ruled surface with the central ruled surface in n-dimensional Minkowski space, R_1^n  is studied. The relationship between normal sectional curvature and the princ... see more

We obtain a conceptually new differential geometric proof of P. F. Klembeck’s result (cf. [9]) that the holomorphic sectional curvature k g (z ) of the Bergman metric of a strictly pseudoconvex domain O ? C n approaches -4/(n + 1) (the constant sectional ... see more

Purpose: To investigate the correlation between anterior corneal curvature power (CP) and axial ocular dimensions in emmetropic eyes of healthy children in Gaza. Methods: Ninety six emmetropic eyes of healthy female children aged 13 to 15 years (mean = 14... see more

In this paper, the sectional curvature of non-degenerate tangent sections of time-like ruled surface with the central ruled surface in n-dimensional Minkowski space, R_1^n  is studied. The relationship between normal sectional curvature and the princ... see more

There are several generalizations of the concept of semi-symmetric Riemannian manifolds. In the present paper, we consider some special types of generalized semi-symmetric Riemannian manifolds with positive or negative defined curvature operator or sectio... see more

We give non-degeneracy criteria for Riemannian simplices based on simplices in spaces of constant sectional curvature. It extends previous work (SoCG15) on Riemannian simplices, where we developed Riemannian simplices with respect to Euclidean reference s... see more

This study investigates the effect of curvature ratio on the liquid-gas mixing in an air humidification process by choosing the optimum positioning of nozzles matrix fixed prior to a bent duct. The present study is considered as a simulation of the gas tu... see more

Conduit (pipes) in reinforced concrete columns is still used to date. ACI 318M-95 code limits the hole up to maximum 4% of the column cross sectional area. If the percentage is more than 4%, its effect toward its strength should be considered. But the Cod... see more

Introduction: A large number of hormonal, metabolic, immunologic and haematological changes occur in all organ system of female body during pregnancy. Human eye and its function are no exception to these changes.Purpose: To evaluate physiological ocular c... see more
