Compliant vertical access risers (CVARs) are considered as efficient and robust alternative options to achieve cost efficiency safety. Design uncertainties emerge owing the limited understanding of effects various parameters related structural properties marine loads. In this paper, a reasonable three-dimensional (3D) numerical model CVAR with internal flow is presented based on slender rod the...

Flexible cylinders, such as marine risers, often experience sustained vortex-induced vibrations (VIVs). Installing helical strakes on a riser is the most widely used technique to mitigate VIVs. This study was inspired by giant Saguaro Cacti which can withstand strong wind with shallow root system. In this study, numerical simulations of flow past stationary cylinder cactus-shaped cross-section ...

Many companies in India manufacture solar water heaters but these are not becoming popular in the domestic sector because of their high cost. The Ministry of Non-Conventional Energy Sources (MNES), New Delhi is recommending flat-plate collectors with copper (Cu) risers, headers and plate. Therefore, their cost is high. Long term studies have been carried out at the Central Arid Zone Research In...

Introduction Stair falls can be caused by inconsistent stair dimensions. During ascent, inconsistently taller risers lead to reduced foot clearances as the inconsistency goes unnoticed. A horizontal-vertical illusion increases perceived riser heights and clearance could offset over risers, though this might impact other safety measures. Method Twelve participants (age: 22 (3) years) ascended a ...

BACKGROUND The prognostic significance of ambulatory blood pressure (ABP) has not been established in patients with type 2 diabetes (T2DM). METHODS In order to clarify the impact of ABP on cardiovascular prognosis in patients with or without T2DM, we performed ABP monitoring (ABPM) in 1,268 subjects recruited from nine sites in Japan, who were being evaluated for hypertension. The mean age of...
