BACKGROUND There is a limited data on the association between serum uric acid (SUA) and cardiovascular disease (CVD) among the very elderly population. AIMS We evaluated the association of SUA, highly sensitive C-reactive protein (hs-CRP, a marker of vascular and systemic inflammation), and coronary artery calcification (CAC, a marker of subclinical CVD)(More)
This paper presents the results of an experimental work carried out to find the wall pressure distribution in a suddenly expanded duct. The enlarged duct is attached to the exit of a convergentdivergent axisymmetric nozzle. The area ratio (i.e. ratio between cross sectional area of the sudden expansion duct and the nozzle exit area) considered in the(More)
The paper presents the study of unguided rolling projectiles at varying Mach numbers using aerodynamic coefficients. The aerodynamic coefficients are estimated using an aerodynamic prediction code, Missile DATCOM. The predicted dynamic derivatives will determine the design criteria, and also their effect on the design aspects (stability and accuracy) of the(More)
This paper presents results of an experimental investigation carried out to control the base pressure in a suddenly expanded axisymmetric passage. Four micro-jets of 1 mm orifice diameter located at 90 0 intervals along a pitch circle diameter of 1.3 times the nozzle exit diameter in the base region were employed as active controls. The tests were conducted(More)
BACKGROUND AND AIMS Depression is a mood disorder characterized by persistent feelings of loss of interest along with a cluster of clinical symptoms. It is a significant public health concern affecting 350 million people worldwide. Depression has an association with increased risk of cardiovascular disease. The World Health Organization estimates both(More)
The experiments were carried out to assess the effect of Mach number on base pressure and control effectiveness in a suddenly expanded duct. In the present study the Mach number at the nozzle exit and the nozzle pressure ratio (NPR) are the flow parameters considered. The area ratio (i.e. ratio between cross sectional area of the sudden expansion duct and(More)
