In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area . Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), [ 1 ] while high-pressure areas are ...
In 2013, HSA convened a workshop on Low Atmospheric Pressure Stunning (LAPS), [42] [43] a proposal to kill chickens by withdrawing air from a chamber over the course of 5 minutes. The lack of oxygen induces unconsciousness without a rise in heart rate and with brain activity that resembles a sleep-like state before death.
More humane methods that could be used are low atmospheric pressure stunning and inert gas asphyxiation. [53] According to animal charities, carrying chickens by their legs is inhumane. The European Commission advocates for this practice and the UK government is intending to legalize it. [54] [55]
A low-pressure area is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere. [1] The formation process of a low-pressure area is known as cyclogenesis. [2]
Hypobaric decompression is the reduction in ambient pressure below the normal range of sea level atmospheric pressure. Altitude decompression is hypobaric decompression which is the natural consequence of unprotected elevation to altitude, while other forms of hypobaric decompression are due to intentional or unintentional release of pressurization of a pressure suit or pressurized compartment ...
Modified atmosphere packaging (MAP) is the practice of modifying the composition of the internal atmosphere of a package (commonly food packages, drugs, etc.) in order to improve the shelf life. [ 1 ] [ 2 ] The need for this technology for food arises from the short shelf life of food products such as meat, fish, poultry, and dairy in the ...
This fall in profitability was accompanied by a general fall in prices to the consumer, allowing poultry and eggs to lose their status as luxury foods. Robert Plamondon [36] reports that the last family chicken farm in his part of Oregon, Rex Farms, had 30,000 layers and survived into the 1990s. However, the standard laying house of the current ...
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars , [ 1 ] 760 mm Hg , 29.9212 inches Hg , or 14.696 psi .
