The manning of a ship is a major driver of total ownership cost. The Government Accounting Office (GAO) states that “the cost of the ship’s crew is the largest expense incurred over the ship’s lifetime” [1]. This cost is largely determined by decisions made during concept design, which may include significant new support costs ashore. Consequently, reliable manpower estimates and related design...

Counterion condensation is a basic feature of 2D electrostatics exhibited by highly charged rodlike polymers such as DNA. In the framework of the Poisson Boltzmann equation with salt, we show that such a polymer of radius a attracts a condensate of thickness RM=A(axi)1/2 where xi is the Debye length and A depends weakly on the polymer charge density q0. To leading order in 1/ln(xi/a), we derive...

OBJECTIVE The quality of documentation of signs and symptoms and validation of the diagnosis of irritable bowel syndrome (IBS) according to case definition criteria of Manning, Rome I and Rome II in an office setting has not been previously described. We sought to identify and validate cases of IBS based on the Manning, Rome I and Rome II diagnostic criteria in a rural practice setting. SETTI...

En el diseño de sistemas riego multisalidas es necesario calcular las pérdidas energía por fricción en tuberías y determinar diámetro más económico óptimo, para ello existen ecuaciones Manning, Hanzen & Williams Darcy Wesbach. De acuerdo con lo anterior objetivo este trabajo fue realizar un análisis físico matemático a rozamiento accesorios generar al menos una ecuación determinística basad...
