Subject field(s)
  • Collaboration with the FAO
  • Ecology (General)
  • Environmental Management
  • Commercial Fishing
CONT

... the fish stock can be augmented to enable a continuing availability through time. Thus fish... have the special feature that even though their utilisation results in depletion, new stocks are created by a process of self-generation. The regeneration occurs at a "natural" rate, often directly dependent upon the amount of original stock remaining unutilised.

DEF

A stable crystalline form of nitric acid and water, consisting of three molecules of water for every molecule of nitric acid.

CONT

Studies of the Antarctic ozone hole have shown that polar stratospheric clouds(PSCs) play an important role in the depletion of ozone. The PSCs contribute to ozone depletion by cycling chlorine from inactive "reservoir" species such as ClONO2 and HCl into reactive chlorine atoms. Although it is known that one type of PSC particle(Type Ia) contains nitric acid and water in a crystalline form, the composition and formation mechanism of these particles is not yet known. We measured the crystallization rates of nitric acid trihydrate(NAT) and nitric acid dihydrate(NAD) to determine the amount of time which would be required for 3 : 1 and 2 : 1 water : nitric acid solutions to freeze to NAT and NAD, respectively, under stratospheric conditions.

CONT

Lorsque la température en hiver décroît au-dessous d'un seuil, approximativement 195 K, de petites particules solides contenant un mélange d'acide nitrique et d'eau (certainement de l'acide nitrique trihydrate - NAT) se forment et produisent des nuages stratosphériques polaires (polar stratospheric clouds - PSC) dits de type I.

CONT

[...] les PSC [polar stratospheric clouds, en français : nuages stratosphériques polaires] de type Ia [...] sont composés de particules solides de trihydrate d'acide nitrique (acronyme anglais «NAT» signifiant «Nitric Acid Trihydrate») avec une molécule d'acide nitrique pour trois molécules d'eau [...] La température de formation des NAT est typiquement de 5 à 6 degrés supérieure à la température du point de congélation de l'eau, ce qui confère aux PSC Ia une durée de vie plus longue que les PSC II dans l'hémisphère nord.

Subject field(s)
  • Aircraft Propulsion Systems
CONT

Fuel starvation and fuel exhaustion(sometimes referred to as fuel depletion) are problems that can affect internal combustion engines fuelled by either diesel, kerosene, petroleum or any other combustible liquid or gas. If no fuel is available for an engine to burn, it cannot function. All modes of transport powered by such engines can be affected by this problem, but the consequences are most significant when it occurs to aircraft in flight. There are two main ways that an engine can run out of fuel :-Using up fuel. This is the most common cause of fuel exhaustion. An engine can use up all available fuel due to insufficient fuel being loaded for the planned journey or the journey time extended for too long(in the case of an aircraft, due to in-flight delays or problems)... ;-Leaking. In some cases, the fuel tank or the supply piping to the engine leaks and fuel is lost. This can cause engines to starve.

Rosin-based : These antifoulings can have either low or high quantities of rosin. The products with a low level of rosin are hard and are referred to as contact leaching antifoulings. They are mechanically tough, have no polishing characteristics and commonly have a maximum in-service lifetime of 24 months... The high rosin products are softer, dissolve slowly in seawater over time and are referred to as controlled depletion polymer(CDP) antifoulings. These products have in-service lifetimes of up to 36 months on the vertical sides and up to 60 months on the flat bottom...

Record 6 2006-03-16

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
  • Hydrology and Hydrography
DEF

Period of abnormally dry weather sufficiently prolonged to give rise to a shortage of water as evidenced by below normal streamflow and lake levels and/or the depletion of soil moisture and a lowering of groundwater levels.

CONT

Hydrological drought refers to deficiencies in surface and subsurface water supplies. It is measured as streamflow, and as lake, reservoir and ground water levels. There is a time lag between lack of rain and less water in streams, rivers, lakes and reservoirs, so hydrological measurements are not the earliest indicators of drought. When precipitation is reduced or deficient over an extended period of time, this shortage will be reflected in declining surface and subsurface water levels.

CONT

Drought is viewed as a sustained and regionally extensive occurrence of below average natural water availability, either in the form of precipitation, river runoff, or groundwater. Droughts may be classified as meteorological or hydrological : A Meteorological Drought occurs when there is below average availability of precipitation.... A Hydrological Drought is marked by a deficit in the runoff of rivers where discharge(flow) remains below a low threshold or the rivers dry up completely and remain dry for a very long time and a significant natural depletion of aquifers(groundwater). The low threshold flow is the 10-year return period 7-day minimum mean flow.

DEF

Période de temps anormalement sec, suffisamment prolongée pour entraîner une pénurie d'eau caractérisée par un abaissement significatif de l'écoulement des cours d'eau, des niveaux des lacs et/ou des nappes souterraines, les amenant à des valeurs inférieures à la normale, et/ou un assèchement anormal du sol.

CONT

[...] si la sécheresse est un risque limité dans le temps, elle n'agit pas moins directement sur l'ensemble du milieu car son impact se transmet de la pluie (sécheresse climatique) au sol (sécheresse édaphique) aux produits de la terre (sécheresse agricole) et aux nappes aquifères (sécheresse hydrologique).

OBS

On écrirait mieux «sècheresse».
