Navigation in crowded and restricted waters

Transport Reviews, 1981
Abstract The freedom of the seas, or the right of innocent passage whereby the Master of a ship may proceed as and how he chooses has, in recent years, come under considerable public scrutiny. This scrutiny has resulted in an increasing intervention by land‐based authorities to limit the traditional freedoms, by means of regulating the flow of shipping

The behaviour of a ship in restricted waters

International Shipbuilding Progress, 1977
This paper deals with the problem of the behaviour of a ship in restricted waters with special regard to underkeel clearance. The main factors affecting the keel clearance are squat, heaving and pitching motions, the occurrence of a heeling angle due to windpressure and ruddermovements and the rolling motion.

Enzymatic transesterifications of carbonates in water‐restricted environments

Biotechnology and Bioengineering, 1989
AbstractWe investigated the ability of several hydrolases to catalyze reactions with an abiotic water‐insoluble substrate, carbonic acid diphenyl ester, also known as diphenyl carbonate (DPC). In single‐phase water/organic systems, turnover numbers (TN) of greater than 2 × 104 min−1have been achieved for the hydrolysis of DPC.

Vessel Controllability in Restricted Waters

Journal of the Waterways, Harbors and Coastal Engineering Division, 1971
Existing knowledge of hydrodynamic factors affecting the movement of a ship in restricted waterways is critically examined. It is shown that the external forces can be either active, such as rudder power from either engine or rudder (and even tugboats), or passive, such as improved communications which enable quicker response to a change in ...

Liquid Water Restricts Habitability in Extreme Deserts

Astrobiology, 2017
Liquid water is a requirement for biochemistry, yet under some circumstances it is deleterious to life. Here, we show that liquid water reduces the upper temperature survival limit for two extremophilic photosynthetic microorganisms (Gloeocapsa and Chroococcidiopsis spp.) by greater than 40°C under hydrated conditions compared to desiccated conditions.

Enhanced self-diffusion of water in restricted geometry

Physical Review Letters, 1989
Self-diffusion of water contained in a porous glass is observed to be strongly enhanced if the pore space is only partially filled. This can be explained by a novel mechanism involving indirect molecular exchange between the liquid and the vapor phase.

The pathophysiological effects of water and feed restriction in chickens

Avian Pathology, 1991
Three-to-five days of water restriction in 5-week-old chickens produced mild dilatation of tubules in distal nephron segments and epithelial necrosis. Most dilated tubules were empty or contained proteinaceous casts. The histopathological changes were more frequent in the left kidney.

A navigation system for restricted waters

Ocean 73 - IEEE International Conference on Engineering in the Ocean Environment, 1973
A combination of Raydist "T" and WANG Programmable Calculator Systems provides a capability for local precise navigation over large areas of up to 10,000 square miles. Daytime positioning accuracy of 10 yards is usual for an unlimited number of users.

Endocrine and renal response to water loading and water restriction in normal man

Clinical Science, 1988
1. Nine normal subjects (eight male, one female) on a fixed daily intake of 150 mmol of sodium and 80 mnol of potassium, were randomized to receive either 3 days of 1.0 litre total water intake/24 h (food + fluid) or 4 days of 6.8 litres total water intake/24 h, and were then crossed over after a 3 day control period (2.7 litres water/24 h).
