Low atmospheric pressure tends to occur over warm water and high pressure occurs over cold water, in part because of deep convection over the warm water.

When the water level is below both switches, the switch contacts are closed providing signals to both the " Low Level " and " High Level " inputs to the PLC.

The software-created " Fill Valve " contact latches the circuit so that even when the " Low Level " input goes away as the water begins to rise, the fill valve remains on.

“ Low water and occasional drying of the wetland bottom during droughts ( dry marsh phase ) stimulate plant recruitment from a diverse seed bank and increase productivity by mobilizing nutrients.

Low water levels have caused groundwater contamination through the springs adding to the regional controversies over water use, endangered suckers ( fish ) and struggling salmon species, and farming.

Low water level uncovers the core, allowing it to heat up.

Low head dams are insidiously dangerous because their danger cannot be easily recognized by people who have not studied swift water.

Low humidity conditions or watering the plants with a water source which contains high levels of dissolved salts will result in the leaves yellowing and rapidly dying from the tips back to the rhizome.

Before the discovery of iron and sulphur rich water, Harrogate comprised two hamlets, High Harrogate and Low Harrogate, close to the historic town of Knaresborough.

Low water Bridge at Ponca

Low pressure at the center of a weather system also has a small secondary effect, as can the bathymetry of the body of water.

Low quality housing and the poor water supply near the dockyard led to a lack of workers and caused construction delays, and the first dry-dock was not completed until 1708.

Low water temperatures make it necessary for divers to wear diving suits and can cause problems such as freezing of diving regulators.

Low flow shower heads, less than or equal 7. 6 liters per minute ( 2. 0 gallon per minute ), can use water more efficiently by aerating the water stream, altering nozzles through advanced flow principles or by high speed oscillation of the spray stream.

In June, there is a firefly festival, and fireflies can easily be seen from many of the " chinkabashi " ( Low water crossing ).

Low temperature is a commonly reported trigger of acute gout: an example would be a day spent standing in cold water, followed by an attack of gout the next morning.

Low Flow policy pertains to states and tribes water quality standards that identify procedures applied to determining critical low flow conditions.

Circulation of surface wind and ocean water is anticlockwise in the Northern Hemisphere, around a low-pressure area, such as the persistent Aleutian Low and the Icelandic Low.

Low temperature thermometry.

* Lancaster University, Ultra Low Temperature Physics – includes a summary of some low temperature techniques

Low temperature, starvation of the cells and high multiplicity of infection ( MOI ) are known to favor lysogeny ( see later discussion ).

Low sea levels may have also exacerbated temperature extremes.

* Low temperature cooking

* Low thermal gradients coupled with a high wall rock temperature, explaining the preponderance for pegmatite to occur only within greenschist metamorphic terranes

Show Low has twice reached 100 ° F ( 38 ° C ), its record high temperature: once on May 31, 1969, and again on July 14, 2003.

Low temperature prolongs dormancy.

Low body temperature results in shivering becoming more violent.

" Low temperature thermal behaviour of chitins and chitin-glucans ".

Low dark current at room temperature.

The product describes the expected sky condition ( along with the chance of precipitation and precipitation type if liquid and / or frozen precipitation is forecast ), the temperature range for the county zone ( typically written out as for example: " Lows in the lower 50s ", though sometimes if temperatures in the county zone are forecast to be around a specific temperature it may be written as " Low around 55 ") and the forecast winds ; the wind forecast only appears within the first 72 hours of the seven-day period in the product.

* Low temperature.

It's clear, given these prerequisites, that contact pressure and developed temperature is highly dependent on the lumps geometry. Flow of material exhibits an increase in energy density, because initial phase transformation and displacement of material demand acceleration of material and high pressure. Low pressure is not compatible with plastic flow, only after deceleration may the flowing material be exposed to low pressure and quickly cooled.

Low temperature gas sterilizers function by exposing the articles to be sterilized to high concentrations ( typically 5-10 % v / v ) of very reactive gases ( alkylating agents such as ethylene oxide, and oxidizing agents such as hydrogen peroxide and ozone ).

Kuerten, Thermodynamics and hydrodynamics of < sup > 3 </ sup > He -< sup > 4 </ sup > He mixtures, Progress in Low Temperature Physics, XIII, 167-218 ( 1992 )</ ref > The pressure in the still is kept low ( about 10 Pa ) by the pumps at room temperature.

* Low temperature cooking

Low power pool-type reactors such as the SLOWPOKE and TRIGA have been licensed for unattended operation in research environments because as the temperature of the low-enriched ( 19. 75 % U-235 ) uranium alloy hydride fuel rises, the molecular bound hydrogen in the fuel cause the heat to be transferred to the fission neutrons as they are ejected.

Low air temperature higher up can be masked by high insolation under clear skies, but will take its effect with increased cloud cover.

* Low temperature polymer fuel cell membranes can be poisoned by the carbon monoxide ( CO ) produced by the reactor, making it necessary to include complex CO-removal systems.

Low melting temperature.
